為了改善垂直配向式(Vertical Alignment；VA)液晶顯示器的側視角偏白(Color Washout)情形，在空間上將子畫素(或是畫素)分為兩個或兩個以上的群組，並且分別依據查找表中兩個或兩個以上的伽瑪函數 (亮度對灰階的函數)提供不同的電壓給不同的群組，藉此改善側視角偏白的情形。In order to improve the color washout situation of the vertical alignment (Vertical Alignment; VA) liquid crystal display, the sub-pixels (or pixels) are spatially divided into two or more groups, and Provide different voltages to different groups according to two or more gamma functions (functions of brightness vs. grayscale) in the look-up table, thereby improving the white side viewing angle.

然而，依據兩個或兩個以上的伽瑪函數提供不同電壓給不同群組，使得不同群組的子畫素所顯示的亮度根據空間上的劃分方式可能會產生亮暗紋路。舉例而言，在一個實際例子中，若顯示裝置的畫素陣列中第一列的子畫素依據較高亮度的伽瑪函數，產生較亮的亮度；相鄰的第二列的子畫素依據較低亮度的伽瑪函數，產生較低的亮度。依此類推，每一列的子畫素依序存在亮、暗、亮、暗的關係，在這種情形下，在整列的子畫素較亮以及另一整列的子畫素較暗的排列下，會產生較明顯的亮暗紋路。However, different voltages are provided to different groups according to two or more gamma functions, so that the brightness displayed by the sub-pixels of different groups may produce bright and dark lines according to the spatial division method. For example, in a practical example, if the sub-pixels in the first column of the pixel array of the display device generate brighter brightness according to the gamma function of higher brightness; the sub-pixels of the adjacent second column According to the gamma function of lower brightness, lower brightness is produced. By analogy, the sub-pixels of each column are sequentially bright, dark, bright, and dark. In this case, the sub-pixels in the entire column are brighter and the sub-pixels in the other column are darker. , Will produce more obvious bright and dark lines.

因此，為了降低視覺上可能會察覺的亮暗紋路的影響，將多個子畫素以較緊密的排列方式劃分為不同群組。舉例而言，在另一個實際例子中，假設在第一列上相鄰不同行的子畫素分別為亮、暗、亮、暗，另外，在第二列上相鄰不同行的子畫素分別為暗、亮、暗、亮，也就是說，每一個相對亮的子畫素附近上下左右均為相對暗的子畫素，每一個相對暗的子畫素附近上下左右均為相對亮的子畫素，以分散第一列全部的子畫素皆為較亮、第二列全部的子畫素皆為較暗的排列方式。在空間上將相鄰子畫素(或畫素)劃分為不同群組為最小菱格紋(mesh)的排列方式。Therefore, in order to reduce the influence of bright and dark lines that may be visually perceivable, multiple sub-pixels are divided into different groups in a tighter arrangement. For example, in another practical example, suppose that the sub-pixels in different rows adjacent to each other on the first column are bright, dark, bright, and dark, and in addition, the sub-pixels in different rows adjacent to each other on the second column They are dark, bright, dark, and bright respectively. That is to say, each relatively bright sub-pixel is relatively dark sub-pixels up, down, left, and right, and each relatively dark sub-pixel is relatively bright up, down, left, and right. The sub-pixels are arranged in such a way that all the sub-pixels in the first row are lighter, and all the sub-pixels in the second row are darker. Spatially divide adjacent sub-pixels (or pixels) into different groups as the arrangement of the smallest meshes.

一般情形下，同一行中的子畫素耦接於相同的資料線，同一行中的子畫素接收相同極性的顯示資料，相鄰行的資料線的顯示資料的極性相異。然而，在第一列中相鄰的子畫素為不同的亮暗設定，且第一列的子畫素與同一行的第二列的子畫素亦為不同的亮暗設定的排列下，這樣的畫素排列方式會導致嚴重的水平串擾(Horizontal Crosstalk)。In general, the sub-pixels in the same row are coupled to the same data line, the sub-pixels in the same row receive display data of the same polarity, and the data lines of adjacent rows have different polarities of display data. However, when the adjacent sub-pixels in the first column have different light and dark settings, and the sub-pixels in the first column and the sub-pixels in the second column of the same row are also arranged with different light and dark settings, Such pixel arrangement will cause serious horizontal crosstalk (Horizontal Crosstalk).

其中，子畫素的一側接收各自的顯示資料，另一側耦接於所有子畫素共用的共用電極。水平串擾為資料線提供給子畫素的顯示資料透過寄生電容拉高或拉低共用電極的電壓。共用電極的電位偏離原本給定的電壓準位，使得同時接收顯示資料的子畫素(耦接於相同閘極線的子畫素)不能在預期的電壓運作，產生過亮或過暗之偏差。亦即，在相鄰列的子畫素中，當複數條資料線的顯示資料的電壓變化之總和不為零時，便可能拉高或拉低共用電極的電壓，造成水平串擾。Among them, one side of the sub-pixels receives their respective display data, and the other side is coupled to a common electrode shared by all the sub-pixels. Horizontal crosstalk is that the display data provided by the data line to the sub-pixels pulls up or pulls down the voltage of the common electrode through the parasitic capacitance. The potential of the common electrode deviates from the originally given voltage level, so that the sub-pixels (sub-pixels coupled to the same gate line) that receive display data at the same time cannot operate at the expected voltage, resulting in excessively bright or excessively dark deviations . That is, in the sub-pixels of adjacent rows, when the sum of the voltage changes of the display data of the plurality of data lines is not zero, the voltage of the common electrode may be pulled up or down, causing horizontal crosstalk.

舉例而言，奇數行的資料線提供第一列的子畫素數值為正且數值較高的顯示資料，且提供第二列的子畫素數值為正且數值較低的顯示資料，則奇數行的資料線在提供第一列到第二列的子畫素的顯示資料時，電壓降低，並且拉低共用電極的電位；偶數行的資料線提供第一列的子畫素數值為負且數值較高的顯示資料，且提供第二列的子畫素數值為負且數值較低的顯示資料，則偶數行的資料線在提供第一列到第二列的子畫素的顯示資料時，電壓亦降低，並且亦拉低共用電極的電位。在這樣的群組分配以及資料線極性的設定，因此，隨著顯示資料同時增加或減少的幅值變化，影響了共用電極的電位，造成共用電極的電位頻繁變化偏離原本給定的電壓準位，形成水平串擾。For example, a data line in an odd row provides display data with a positive sub-pixel value in the first row and a higher value, and provides display data with a positive sub-pixel value in the second row and a lower value, then odd When the data line of the row provides the display data of the sub-pixels in the first row to the second row, the voltage is lowered and the potential of the common electrode is lowered; the data line of the even-numbered row provides the sub-pixel value of the first row is negative and Display data with a higher value, and provide display data with a negative sub-pixel value in the second row and a lower value. The data line of the even-numbered row provides display data for the sub-pixels in the first row to the second row. , The voltage is also reduced, and also pull down the potential of the common electrode. In such a group assignment and data line polarity setting, therefore, as the displayed data increases or decreases at the same time, the amplitude changes affect the potential of the common electrode, causing the potential of the common electrode to frequently change from the originally given voltage level. , The formation of horizontal crosstalk.

假設設定某些相鄰資料線提供相同極性的顯示資料以降低水平串擾。然而，相鄰的資料線提供相同極性的顯示資料，則會產生垂直串擾(Vertical Crosstalk)的問題。Assume that some adjacent data lines are set to provide display data of the same polarity to reduce horizontal crosstalk. However, adjacent data lines provide display data of the same polarity, which will cause vertical crosstalk (Vertical Crosstalk) problems.

因此，本揭示文件的一些實施例中提出的顯示裝置，讓相鄰資料線提供相異極性的顯示資料，並且利用調整空間上設定的群組排列的方式來降低視角偏白、亮暗紋路以及水平串擾。為了較佳地理解空間上設定的群組排列的方式以及如何降低水平串擾，將於後續實施例說明。Therefore, the display device proposed in some embodiments of the present disclosure allows adjacent data lines to provide display data of different polarities, and adjusts the spatially set group arrangement to reduce the viewing angle whiteness, bright and dark lines, and Horizontal crosstalk. In order to better understand the spatial arrangement of the groups and how to reduce the horizontal crosstalk, the following embodiments will be described.

請一併參閱第3圖，第3圖繪示根據本實施例當中第1圖及第2圖的畫素列內所顯示之亮度的顯示裝置100的示意圖。Please also refer to FIG. 3. FIG. 3 is a schematic diagram of the display device 100 according to the brightness displayed in the pixel rows of FIG. 1 and FIG. 2 in this embodiment.

如第3圖所示，顯示裝置100包含複數條資料線D1~D12、複數條閘極線G1~G2、資料驅動電路110、閘極驅動電路120以及畫素陣列130a。顯示裝置100的配置與第1圖中的顯示裝置100的配置大致相同，在此不再贅述。As shown in FIG. 3, the display device 100 includes a plurality of data lines D1 to D12, a plurality of gate lines G1 to G2, a data driving circuit 110, a gate driving circuit 120, and a pixel array 130a. The configuration of the display device 100 is substantially the same as the configuration of the display device 100 in Figure 1, and will not be repeated here.

如第3圖所示，畫素陣列130a中的子畫素被劃分為兩個群組。第一群組PH的子畫素包含子畫素P1A 、P1B、P1C、P1G、P1H、P1L、P2D、P2E、P2F、P2I、P2J、P2K，第二群組PL的子畫素包含子畫素P1D、P1E、P1F、P1I、P1J、P1K、P2A、P2B、P2C、P2G、P2H、P2L。As shown in Figure 3, the sub-pixels in the pixel array 130a are divided into two groups. The sub-pixels of the first group PH include sub-pixels P1A, P1B, P1C, P1G, P1H, P1L, P2D, P2E, P2F, P2I, P2J, P2K, and the sub-pixels of the second group PL include sub-pixels P1D, P1E, P1F, P1I, P1J, P1K, P2A, P2B, P2C, P2G, P2H, P2L.

請一併參閱第4A圖。第4A圖繪示根據本案一實施例的查找表。如第4A圖所示，橫軸為灰階(例如0~256灰階)，縱軸為12位元(2^ ¹²=4096個)亮度等級(色彩深度)。查找表中包含標準伽瑪函數(Gamma 2.2 function)G0、第一伽瑪函數GH以及第二伽瑪函數GL。 Please also refer to Figure 4A. Figure 4A shows a look-up table according to an embodiment of this case. As shown in Figure 4A, the horizontal axis is grayscale (for example, 0~256 grayscale), and the vertical axis is 12-bit (2^ ¹² =4096) brightness levels (color depth). The lookup table includes a standard gamma function (Gamma 2.2 function) G0, a first gamma function GH, and a second gamma function GL.

在1~255灰階中任一者，第一伽瑪函數GH的亮度等級大於標準伽瑪函數G0的亮度等級，第二伽瑪函數GL的亮度等級小於標準伽瑪函數G0的亮度等級。亦即，在1~255灰階中之任一者，依據第一伽瑪函數GH而驅動的子畫素與依據第二伽瑪函數GL而驅動的子畫素的亮度平均值，相等於依據標準伽瑪函數G0而驅動的子畫素的亮度。In any one of 1 to 255 gray scales, the brightness level of the first gamma function GH is greater than the brightness level of the standard gamma function G0, and the brightness level of the second gamma function GL is less than the brightness level of the standard gamma function G0. That is, in any one of the gray scales from 1 to 255, the average brightness of the sub-pixels driven according to the first gamma function GH and the sub-pixels driven according to the second gamma function GL is equal to The brightness of the sub-pixel driven by the standard gamma function G0.

第一群組PH子畫素可依據第一伽瑪函數GH決定其顯示的灰階與亮度關係。相較於第一群組PH子畫素，第二群組PL的子畫素可依據亮度等級較暗的第二伽瑪函數GL決定其顯示的灰階與亮度關係。The first group of PH sub-pixels can determine the relationship between the gray scale and the brightness of the display according to the first gamma function GH. Compared with the PH sub-pixels of the first group, the sub-pixels of the second group PL can determine the relationship between the gray scale and the brightness of the display according to the second gamma function GL with a darker brightness level.

在畫素陣列130a中，相同子畫素行且在第一列R1以及第二列R2的兩個相鄰的子畫素的其中一者為第一群組PH的子畫素，另一者為第二群組PL的子畫素。舉例來說，子畫素行C1具有相鄰的子畫素P1A與P2A，子畫素P1A為第一群組PH的子畫素；子畫素P2A為第二群組PL的子畫素。In the pixel array 130a, one of the two adjacent sub-pixels in the same sub-pixel row and in the first column R1 and the second column R2 is the sub-pixel of the first group PH, and the other is the sub-pixel of the first group PH. The sub-pixels of the second group PL. For example, the sub-pixel row C1 has adjacent sub-pixels P1A and P2A. The sub-pixel P1A is a sub-pixel of the first group PH; and the sub-pixel P2A is a sub-pixel of the second group PL.

並且，在畫素陣列130a的第一列R1的子畫素P1A~P1L以及第二列R2的子畫素P2A~P2L之中，由於在相同子畫素行(相同顏色的子畫素)的第一群組PH的子畫素以及第二群組PL的子畫素是依據相同灰階而驅動，並且第一群組PH的子畫素以及第二群組PL的子畫素分別是依據第一伽瑪函數GH以及第二伽瑪函數GL而驅動，使得在相同子畫素行(相同顏色的子畫素)的第一群組PH的子畫素的顯示電壓的絕對值可大於第二群組PL的子畫素的顯示電壓的絕對值，因此，在相同子畫素行(相同顏色的子畫素)的第一群組PH的子畫素以及第二群組PL的子畫素之間具有一電壓差，這個電壓差使得這兩個子畫素之間具有亮度對比。並且，在相同子畫素行的第一群組PH的子畫素的亮度以及第二群組PL的子畫素的亮度的平均亮度為依據標準伽瑪函數G0在相同灰階而驅動的子畫素的亮度。In addition, among the sub-pixels P1A~P1L in the first column R1 of the pixel array 130a and the sub-pixels P2A~P2L in the second column R2, since they are in the first row of the same sub-pixel row (sub-pixels of the same color) The sub-pixels of a group of PH and the sub-pixels of the second group of PL are driven according to the same gray scale, and the sub-pixels of the first group of PH and the sub-pixels of the second group of PL are respectively driven according to the first group A gamma function GH and a second gamma function GL are driven so that the absolute value of the display voltage of the sub-pixels of the first group PH in the same sub-pixel row (sub-pixels of the same color) can be greater than that of the second group The absolute value of the display voltage of the sub-pixels of the group PL, therefore, between the sub-pixels of the first group PH and the sub-pixels of the second group PL of the same sub-pixel row (sub-pixels of the same color) There is a voltage difference, which makes the brightness contrast between the two sub-pixels. In addition, the average brightness of the sub-pixels of the first group PH and the second group of PL in the same sub-pixel row are the sub-pictures driven in the same gray scale according to the standard gamma function G0. The brightness of the element.

亦即，在畫素陣列130a中，十二個子畫素行C1~C12具有12個電壓差。請一併參閱第1圖以及第3圖。P2A的顯示電壓減去P1A的顯示電壓為第一電壓差；P2B的顯示電壓減去P1B的顯示電壓為第二電壓差；P2C的顯示電壓減去P1C的顯示電壓為第三電壓差，依此類推，P2D~P2L的顯示電壓減去P1D~P1L的顯示電壓依序為第四電壓差至第十二電壓差。That is, in the pixel array 130a, the twelve sub-pixel rows C1 to C12 have 12 voltage differences. Please refer to Figure 1 and Figure 3 together. The display voltage of P2A minus the display voltage of P1A is the first voltage difference; the display voltage of P2B minus the display voltage of P1B is the second voltage difference; the display voltage of P2C minus the display voltage of P1C is the third voltage difference, and so on By analogy, the display voltage of P2D~P2L minus the display voltage of P1D~P1L is the fourth voltage difference to the twelfth voltage difference in order.

在紅色子畫素行中，電壓差的總和為子畫素行C1、C4、C7以及C10中紅色子畫素P2A、P2D、P2G、P2J的顯示電壓各自減去在相應子畫素行的紅色子畫素P1A、P1D、P1G、P1J的顯示電壓的電壓差的總和，且將在紅色子畫素行中的電壓差的總合稱為第一數值V1。In the red sub-pixel row, the total voltage difference is the display voltage of the red sub-pixels P2A, P2D, P2G, and P2J in the sub-pixel rows C1, C4, C7, and C10 minus the red sub-pixel in the corresponding sub-pixel row. The sum of the voltage differences of the display voltages of P1A, P1D, P1G, and P1J, and the sum of the voltage differences in the red sub-pixel row is referred to as the first value V1.

在綠色子畫素行中，電壓差的總和為子畫素行C2、C5、C8以及C11中綠色子畫素P2B、P2E、P2H、P2K的顯示電壓各自減去在相應子畫素行的綠色子畫素P1B、P1E、P1H、P1K的顯示電壓的電壓差的總和，且將在綠色子畫素行中的電壓差的總合稱為第二數值V2。In the green sub-pixel row, the sum of the voltage difference is the display voltage of the green sub-pixels P2B, P2E, P2H, P2K in the sub-pixel rows C2, C5, C8, and C11 minus the green sub-pixel in the corresponding sub-pixel row. The sum of the voltage differences of the display voltages of P1B, P1E, P1H, and P1K, and the sum of the voltage differences in the green sub-pixel row is referred to as the second value V2.

在藍色子畫素行中，電壓差的總和為子畫素行C3、C6、C9、C12中藍色子畫素P2C、P2F、P2I、P2L的顯示電壓各自減去在相應子畫素行的藍色子畫素P1C、P1F、P1I、P1L的顯示電壓的電壓差的總和，且將在藍色子畫素行中的電壓差的總合稱為第三數值V3。In the blue sub-pixel row, the sum of the voltage difference is the display voltage of the blue sub-pixels P2C, P2F, P2I, and P2L in the sub-pixel rows C3, C6, C9, and C12 respectively minus the blue in the corresponding sub-pixel row The sum of the voltage differences of the display voltages of the sub-pixels P1C, P1F, P1I, and P1L, and the sum of the voltage differences in the blue sub-pixel row is referred to as the third value V3.

亦即，在紅色子畫素行中的電壓差的總合(第一數值V1)為第一電壓差、第四電壓差、第七電壓差以及第十電壓差的總和；在綠色子畫素行中的電壓差的總合(數值V2)為第二電壓差、第五電壓差、第八電壓差以及第十一電壓差的總和；在藍色子畫素行中的電壓差的總合(第三數值V3)為第三電壓差、第六電壓差、第九電壓差以及第十二電壓差的總和。That is, the sum of the voltage differences in the red sub-pixel row (the first value V1) is the sum of the first voltage difference, the fourth voltage difference, the seventh voltage difference, and the tenth voltage difference; in the green sub-pixel row The sum of the voltage differences (value V2) is the sum of the second voltage difference, the fifth voltage difference, the eighth voltage difference, and the eleventh voltage difference; the sum of the voltage differences in the blue sub-pixel row (the third The value V3) is the sum of the third voltage difference, the sixth voltage difference, the ninth voltage difference, and the twelfth voltage difference.

如第3圖所示，在畫素陣列130a中，在第一列的子畫素P1A~P1L依序為PH、PH、PH、PL、PL、PL、PH、PH、PL、PL、PL、PH；在第二列的子畫素P2A~P2L依序為PL、PL、PL、PH、PH、PH、PL、PL、PH、PH、PH、PL。因此，在子畫素行C1~C12上且在第一列R1的第一子畫素的亮度相較於在相應的子畫素行C1~C12上且在第二列R2的第二子畫素的亮度具有十二個亮度對比，這十二個亮度對比依序為”亮、亮、亮、暗、暗、暗、亮、亮、暗、暗、暗及亮”。As shown in Figure 3, in the pixel array 130a, the sub-pixels P1A~P1L in the first column are PH, PH, PH, PL, PL, PL, PH, PH, PL, PL, PL, PH; The sub-pixels P2A~P2L in the second column are PL, PL, PL, PH, PH, PH, PL, PL, PH, PH, PH, PL in sequence. Therefore, the brightness of the first sub-pixel on the sub-pixel rows C1~C12 and in the first column R1 is compared with that of the second sub-pixel on the corresponding sub-pixel rows C1~C12 and in the second column R2. The brightness has twelve brightness contrasts, and the twelve brightness contrasts are sequentially "bright, bright, bright, dark, dark, dark, bright, bright, dark, dark, dark, and bright".

並且，資料驅動電路110分別經由資料線D1~D12提供給子畫素行C1~C12中的子畫素的資料訊號的極性依序為”正、負、正、負、正、負、正、負、正、負、正及負”。In addition, the polarity of the data signal provided by the data driving circuit 110 to the sub-pixels in the sub-pixel rows C1 to C12 via the data lines D1 to D12 are "positive, negative, positive, negative, positive, negative, positive, negative, respectively". , Positive, negative, positive and negative".

其中，在相同子畫素行的第一群組PH的子畫素的電壓的絕對值可大於第二群組PL的子畫素的電壓的絕對值，使得在極性為正的子畫素行，第一群組PH的子畫素的電壓相較於第二群組PL的子畫素的電壓為高準位；在極性為負的子畫素行，第一群組PH的子畫素的電壓相較於第二群組PL的子畫素的電壓為低準位。Wherein, the absolute value of the voltage of the sub-pixels of the first group PH in the same sub-pixel row can be greater than the absolute value of the voltage of the sub-pixels of the second group PL, so that in the sub-pixel row with a positive polarity, the first The voltages of the sub-pixels of a group PH are higher than the voltages of the sub-pixels of the second group PL; in the sub-pixel rows with negative polarity, the voltages of the sub-pixels of the first group PH are relatively high. The voltage of the sub-pixels in the second group PL is lower than that of the second group PL.

亦即，在畫素陣列130a中，在第一列R1的子畫素行C1~C12上的子畫素P1A~P1L的電壓相較於在第二列R2的相應的子畫素行C1~C12上的子畫素P2A~P2L的電壓依序為高準位、低準位、高準位、高準位、低準位、高準位、高準位、低準位、低準位、高準位、低準位及低準位。That is, in the pixel array 130a, the voltages of the sub-pixels P1A~P1L on the sub-pixel rows C1~C12 of the first column R1 are compared with those on the corresponding sub-pixel rows C1~C12 of the second column R2. The voltages of the sub-pixels P2A~P2L in sequence are high level, low level, high level, high level, low level, high level, high level, low level, low level, high level Level, low level, and low level.

在此情形中，當資料驅動電路110經由資料線D1~D12提供資料訊號給第一列R1的子畫素到第二列R2的子畫素時，資料線D1、D4、D7以及D10的電壓分別都從高準位降至低準位；資料線D2、D5、D8以及D11的電壓分別都從低準位升至高準位；資料線D3以及D6的電壓分別都從高準位降至低準位，資料線D9以及D12的電壓分別都從低準位升至高準位。In this case, when the data driving circuit 110 provides data signals to the sub-pixels of the first row R1 to the sub-pixels of the second row R2 through the data lines D1~D12, the voltages of the data lines D1, D4, D7, and D10 The voltages of the data lines D2, D5, D8, and D11 are all raised from the low level to the high level respectively; the voltages of the data lines D3 and D6 are all reduced from the high level to the low level, respectively Level, the voltages of the data lines D9 and D12 respectively rise from a low level to a high level.

在前述中，第一電壓差至第十二電壓差分別是子畫素行C1~C12中在第二列R2的子畫素的顯示電壓減去在相應子畫素行C1~C12中在第一列R1的子畫素的顯示電壓。In the foregoing, the first voltage difference to the twelfth voltage difference are the display voltages of the sub-pixels in the second column R2 in the sub-pixel rows C1~C12 minus the display voltages in the first column in the corresponding sub-pixel rows C1~C12. The display voltage of the sub-pixel of R1.

亦即，第一、第四、第七及第十電壓差為負數值；第二、第五、第八及第十一電壓差為正數值；第三及第六電壓差為負數值，第九及第十二電壓差為正數值。That is, the first, fourth, seventh, and tenth voltage differences are negative values; the second, fifth, eighth, and eleventh voltage differences are positive values; the third and sixth voltage differences are negative values, and the first The ninth and twelfth voltage difference is a positive value.

並且，在畫素陣列130a中，相同子畫素行的第一群組PH的子畫素以及第二群組PL的子畫素是依據相同灰階而驅動，相同顏色的子畫素也是依據相同灰階而驅動，使得對於相同顏色的子畫素行，資料線的電壓變化幅值一致。Moreover, in the pixel array 130a, the sub-pixels of the first group PH and the sub-pixels of the second group PL of the same sub-pixel row are driven according to the same gray scale, and the sub-pixels of the same color are also driven according to the same gray scale. The gray scale is driven, so that for the sub-pixel rows of the same color, the voltage change amplitude of the data line is the same.

亦即，第一電壓差相等於第四電壓差、第七電壓差以及第十電壓差；第二電壓差相等於第五電壓差、第八電壓差以及第十一電壓差；第三電壓差的絕對值與第九電壓差的絕對值相等；第三電壓差相等於第六電壓差，第九電壓差相等於第十二電壓差，並且第三電壓差為第九電壓差的相反數。That is, the first voltage difference is equal to the fourth voltage difference, the seventh voltage difference, and the tenth voltage difference; the second voltage difference is equal to the fifth voltage difference, the eighth voltage difference, and the eleventh voltage difference; the third voltage difference The absolute value of is equal to the absolute value of the ninth voltage difference; the third voltage difference is equal to the sixth voltage difference, the ninth voltage difference is equal to the twelfth voltage difference, and the third voltage difference is the opposite of the ninth voltage difference.

因此，由於資料訊號的極性以及畫素陣列130a空間上特定的群組劃分，在藍色子畫素行中的電壓差的總合(第三數值V3)為零。Therefore, due to the polarity of the data signal and the specific group division in the pixel array 130a, the sum of the voltage differences in the blue sub-pixel rows (the third value V3) is zero.

換而言之，在任一灰階驅動畫素陣列130a，第三數值V3皆為零。In other words, in any gray scale driving pixel array 130a, the third value V3 is all zero.

並且，在紅色子畫素行中的電壓差的總合(第一數值V1)為負數值，在綠色子畫素行中的電壓差的總合(第二數值V2)為正數值。In addition, the sum of the voltage differences in the red sub-pixel row (first value V1) is a negative value, and the sum of the voltage differences in the green sub-pixel row (the second value V2) is a positive value.

舉例而言，如第4B圖所示，畫素陣列100a待顯示的畫面的色彩灰階(R,G,B)為(192,192,64)，並且在192灰階，依據第一伽瑪函數而驅動的子畫素與依據第二伽瑪函數而驅動的子畫素的電壓差為1.7伏特。亦即，第一、第四、第七、第十電壓差皆為-1.7伏特；第二、第五、第八、第十一電壓差皆為1.7伏特。因此第一數值V1為(-1.7*4)=-6.8伏特，第二數值V2為(1.7*4)=6.8伏特。並且，在任一灰階驅動畫素畫素陣列130a，第三數值V3為零。第一數值V1、第二數值V2以及第三數值V3的總合大致上為零，或者三者總合趨近於零。For example, as shown in FIG. 4B, the color gray scale (R, G, B) of the picture to be displayed by the pixel array 100a is (192, 192, 64), and at the 192 gray scale, it is determined according to the first gamma function. The voltage difference between the driven sub-pixel and the sub-pixel driven according to the second gamma function is 1.7 volts. That is, the first, fourth, seventh, and tenth voltage differences are all -1.7 volts; the second, fifth, eighth, and eleventh voltage differences are all 1.7 volts. Therefore, the first value V1 is (-1.7*4)=-6.8 volts, and the second value V2 is (1.7*4)=6.8 volts. Moreover, in any gray scale driving the pixel pixel array 130a, the third value V3 is zero. The sum of the first value V1, the second value V2, and the third value V3 is substantially zero, or the sum of the three approaches zero.

綜上所述，將畫素陣列130a中的子畫素劃分為第一群組PH以及第二群組PL可以改善側視角偏白的影響。並且，在畫素陣列130a中的子畫素的排列方式可以改善亮暗紋路的情形。進一步而言，在畫素陣列130a中第一群組PH的子畫素以及第二群組PL的子畫素的特定排列方式下，當資料驅動電路提供顯示電壓給第一列R1到第二列R2的子畫素時，部分資料線的電壓降低且部分資料線電壓升高；而不會全部的資料線提供顯示電壓給第一列R1到第二列R2的子畫素時，資料線的電壓全部都是升高或降低。因此，複數條資料線的資料訊號在變化時的電壓差的幅值可以部分抵銷，以改善資料訊號從第一列R1到第二列R2的變化透過寄生電容拉高或降低共用電極的電壓所造成的水平串擾。使得共用電極的電壓準位可以維持在較穩定的電壓準位，以改善水平串擾的影響。In summary, dividing the sub-pixels in the pixel array 130a into the first group PH and the second group PL can improve the effect of the white side view angle. In addition, the arrangement of the sub-pixels in the pixel array 130a can improve the situation of bright and dark lines. Furthermore, in the specific arrangement of the sub-pixels of the first group PH and the sub-pixels of the second group PL in the pixel array 130a, when the data driving circuit provides display voltages to the first row R1 to the second row R1 to the second row When the sub-pixels of row R2, the voltage of some data lines decreases and the voltage of some data lines rises; while not all of the data lines provide display voltages to the sub-pixels of the first row R1 to the second row R2, the data lines All of the voltages are increased or decreased. Therefore, the amplitude of the voltage difference when the data signal of the plurality of data lines changes can be partially offset to improve the change of the data signal from the first row R1 to the second row R2. The parasitic capacitance raises or lowers the voltage of the common electrode. The resulting horizontal crosstalk. The voltage level of the common electrode can be maintained at a relatively stable voltage level to improve the influence of horizontal crosstalk.

為了進一步調整第一數值V1以及第二數值V2的總和，本案的畫素陣列130a中的第一群組PH的子畫素以及第二群組PL的子畫素所依據的查找表並不以第4A圖為限，請進一步參閱第5A圖。In order to further adjust the sum of the first value V1 and the second value V2, the sub-pixels of the first group PH and the sub-pixels of the second group PL in the pixel array 130a of the present case are based on different look-up tables. Figure 4A is limited, please refer to Figure 5A for further details.

第5A圖繪示根據本案另一實施例的查找表。第5A圖中縱軸、橫軸單位以及標號與第4A圖一致，在此不再贅述。如第5A圖所示的查找表包含標準伽瑪函數G0、第一區域中的複數個第一伽瑪函數GH00~GH10以及第二區域中的複數個第二伽瑪函數GL00~GL10。在亮度等級大於或等於標準伽瑪函數G0的第一區域中，包含複數個第一伽瑪GH00~GH10；在亮度等級小於或等於標準伽瑪函數G0的第二區域中，包含複數個第二伽瑪函數GL00~GL10。Figure 5A shows a look-up table according to another embodiment of this case. The vertical axis, horizontal axis unit and reference number in Figure 5A are the same as those in Figure 4A, and will not be repeated here. The look-up table shown in FIG. 5A includes a standard gamma function G0, a plurality of first gamma functions GH00~GH10 in the first region, and a plurality of second gamma functions GL00~GL10 in the second region. In the first area with a brightness level greater than or equal to the standard gamma function G0, there are a plurality of first gammas GH00~GH10; in the second area with a brightness level less than or equal to the standard gamma function G0, there are a plurality of second areas Gamma function GL00~GL10.

複數個第一伽瑪函數GH00~GH10依據複數個分離度比例0~1分別對應至複數個第二伽瑪函數GL00~GL10。複數個分離度比例是第一伽瑪函數GH以及對應的第二伽瑪函數GL與標準伽瑪函數G0分開程度的比例。在0~1的分離度比例中，複數個第一伽瑪函數GH00~GH10分別依據比例0、0.2、0.4、0.6、0.8、1對應至與第一伽瑪函數具有相同分離度比例的第二伽瑪函數GL00~GL10。舉例而言，第一伽瑪函數GH02依據比例0.2對應至第一伽瑪函數GH02；第一伽瑪函數GH06依據比例0.6對應至第一伽瑪函數GH06。然而，在比例0~1中可包含更多數值，本案不以此為限。The plurality of first gamma functions GH00~GH10 respectively correspond to the plurality of second gamma functions GL00~GL10 according to the plurality of resolution ratios 0~1. The plurality of separation ratios are the ratios of the separation degree of the first gamma function GH and the corresponding second gamma function GL from the standard gamma function G0. In the resolution ratio of 0 to 1, the plural first gamma functions GH00~GH10 correspond to the second gamma function with the same resolution ratio as the first gamma function according to the ratios 0, 0.2, 0.4, 0.6, 0.8, and 1. Gamma function GL00~GL10. For example, the first gamma function GH02 corresponds to the first gamma function GH02 according to a ratio of 0.2; the first gamma function GH06 corresponds to the first gamma function GH06 according to a ratio of 0.6. However, more values can be included in the ratio 0~1, and this case is not limited to this.

如第5A圖所示的查找表，分離度比例數值為0~1。分離度比例為0的第一伽瑪函數GH00以及第二伽瑪函數GL00皆為標準伽瑪函數G0。分離度比例為1的第一伽瑪函數GH10是第一函數區域中亮度等級最高的伽瑪函數；分離度比例為1的第二伽瑪函數GL10是第二函數區域中亮度等級最低的伽瑪函數。在0~1的分離度比例中，第一函數區域以及第二函數區域可包含更多伽瑪函數。然而，為易於理解，第5A圖的查找表僅出示部分伽瑪函數，以避免於視覺上過於複雜。As shown in the look-up table in Figure 5A, the value of the separation ratio is 0~1. Both the first gamma function GH00 and the second gamma function GL00 with a resolution ratio of 0 are the standard gamma function G0. The first gamma function GH10 with a resolution ratio of 1 is the gamma function with the highest brightness level in the first function area; the second gamma function GL10 with a resolution ratio of 1 is the gamma function with the lowest brightness level in the second function area function. In the resolution ratio of 0 to 1, the first function area and the second function area may contain more gamma functions. However, for ease of understanding, the look-up table in Fig. 5A only shows part of the gamma function to avoid visually too complicated.

其中，依據第一伽瑪函數GH中任一者而驅動的子畫素與依據對應的第二伽瑪函數GL而驅動的子畫素的平均亮度，相等於依據標準伽瑪函數G0而驅動的子畫素的亮度。請一併參閱第3圖以及第5A圖。如第5A圖所示的實施例，在畫素陣列130a中，在相同子畫素行中(相同顏色)的兩個子畫素分別是依據相同分離度比例的第一伽瑪函數GH以及第二伽瑪函數GL而驅動。舉例而言，在子畫素行C1的子畫素P1A是依據分離度比例為0.6的第一伽瑪函數GH06而驅動，子畫素P2A亦是依據分離度比例為0.6的第二伽瑪函數GL06而驅動。Wherein, the average brightness of the sub-pixels driven according to any one of the first gamma function GH and the sub-pixels driven according to the corresponding second gamma function GL is equal to the average brightness of the sub-pixels driven according to the standard gamma function G0 The brightness of the sub-pixel. Please refer to Figure 3 and Figure 5A together. As shown in the embodiment shown in FIG. 5A, in the pixel array 130a, the two sub-pixels in the same sub-pixel row (same color) are respectively based on the first gamma function GH and the second gamma function with the same separation ratio. Gamma function GL and driven. For example, the sub-pixel P1A in the sub-pixel row C1 is driven by the first gamma function GH06 with a resolution ratio of 0.6, and the sub-pixel P2A is also driven by the second gamma function GL06 with a resolution ratio of 0.6. And drive.

並且，畫素陣列130a中，在相同子畫素行中的兩個子畫素所依據的分離度比例係由所顯示畫面中各個顏色(紅色、綠色以及藍色)的灰階決定。由於在任一灰階，在藍色子畫素行中的電壓差的總合 (第三數值V3)皆為零，因此只需調整紅色子畫素的分離度比例或者調整綠色子畫素的分離度比例。In addition, in the pixel array 130a, the separation ratio of the two sub-pixels in the same sub-pixel row is determined by the gray scale of each color (red, green, and blue) in the displayed image. Since at any gray level, the sum of the voltage differences in the blue sub-pixel rows (the third value V3) is zero, only adjust the separation ratio of the red sub-pixels or adjust the separation of the green sub-pixels Proportion.

當紅色灰階與綠色灰階不相等時，調整紅色子畫素的分離度比例或者調整綠色子畫素的分離度比例，使在紅色子畫素行中的電壓差的總合(第一數值V1)的絕對值與在綠色子畫素行中的電壓差的總合(第二數值V2)的絕對值大致相等。When the red gray scale is not equal to the green gray scale, adjust the separation ratio of the red sub-pixels or adjust the separation ratio of the green sub-pixels to make the sum of the voltage differences in the red sub-pixel rows (the first value V1 The absolute value of) is approximately equal to the absolute value of the sum of the voltage differences in the green sub-pixel row (the second value V2).

在一些實際例子中，在亮度11.89~142.3燭光每平方公尺(cd/m ²)的亮度範圍內人類的視覺上可察覺的亮度差異與背景亮度的關係的比值約為1.7%。在本案中為了將亮度差異降低至人類的視覺上無法察覺的範圍內，設定第一電壓差、第二電壓差、第四電壓差以及第五電壓差之總和的絕對值小於450毫伏特，以避免人類的視覺上可察覺的亮度差異。上述總和的絕對值小於450毫伏特是舉例說明，實際應用中隨著顯示器具有不同的尺寸或是不同的驅動電壓規格，例如，具有較小驅動電壓的顯示器，可以將上述總和的絕對值設定在較小數值，以可避免人類的視覺可察覺的亮度差異。另一方面，對於具有較大驅動電壓的顯示器，則可將上述總和的絕對值設定在較大數值。因此，本揭示文件不以此為限。 In some practical examples, in the brightness range of 11.89-142.3 candles per square meter (cd/m ² ), the ratio of the relationship between the human visually perceptible brightness difference and the background brightness is about 1.7%. In this case, in order to reduce the brightness difference to a range that is imperceptible to human vision, the absolute value of the sum of the first voltage difference, the second voltage difference, the fourth voltage difference, and the fifth voltage difference is set to be less than 450 millivolts. Avoid human visually perceivable brightness differences. The absolute value of the above sum is less than 450 millivolts as an example. In practical applications, as displays have different sizes or different driving voltage specifications, for example, for displays with smaller driving voltages, the absolute value of the above sum can be set at A smaller value can avoid the difference in brightness that is perceivable by human vision. On the other hand, for a display with a larger driving voltage, the absolute value of the above sum can be set to a larger value. Therefore, this disclosure is not limited to this.

在本案的一些實施例中，藉由調整紅色子畫素的分離度比例或調整綠色子畫素的分離度比例，使得第一電壓差、第二電壓差、第四電壓差以及、第五電壓差之總和的絕對值小於450毫伏特。In some embodiments of this case, by adjusting the separation ratio of the red sub-pixels or adjusting the separation ratio of the green sub-pixels, the first voltage difference, the second voltage difference, the fourth voltage difference, and the fifth voltage The absolute value of the sum of the differences is less than 450 millivolts.

此外，藉由調整紅色子畫素的分離度比例或調整綠色子畫素的分離度比例，使得第七電壓差、第八電壓差、第十電壓差以及、第十一電壓差之總和的絕對值小於450毫伏特。並且，在藍色子畫素行中的電壓差的總合 (第三數值V3)皆為零。In addition, by adjusting the separation ratio of the red sub-pixels or adjusting the separation ratio of the green sub-pixels, the absolute sum of the seventh voltage difference, the eighth voltage difference, the tenth voltage difference, and the eleventh voltage difference The value is less than 450 millivolts. Also, the sum of the voltage differences in the blue sub-pixel rows (the third value V3) are all zero.

換而言之，第一電壓差至第十二電壓差的總和(第一數值V1、第二數值V2以及第三數值V3的總和)需小於900毫伏特，以避免人類的視覺上可察覺的亮度差異。In other words, the sum of the first voltage difference to the twelfth voltage difference (the sum of the first value V1, the second value V2, and the third value V3) needs to be less than 900 mV to avoid visually perceivable by humans.

舉例而言，請參閱第5B圖，畫素陣列100a待顯示的畫面的色彩灰階(R,G,B)為(192,64,128)，並且依據紅色灰階、綠色灰階、藍色灰階的分離度比例(0.8,1,1)來驅動子畫素。其中在192灰階，依據分離度比例為0.8的第一伽瑪函數以及第二伽瑪函數而分別驅動的子畫素的電壓差亦為1.35伏特。亦即，第一、第四、第七、第十電壓差皆為-1.35伏特。因此第一數值V1為(-1.35*4)=-5.4伏特。其中在64灰階，依據分離度比例為1的第一伽瑪函數以及第二伽瑪函數而分別驅動的子畫素的電壓差為1.25伏特。亦即，第二、第五、第八、第十一電壓差皆為1.25伏特。因此第二數值V2為(1.25*4)=5伏特。並且，在任一灰階驅動畫素畫素陣列130a，第三數值V3為零。第一數值V1、第二數值V2以及第三數值V3的總和為等於-0.4伏特(-5.4伏特+5伏特)，其絕對值小於900毫伏特。如此一來，可以避免人類的視覺上可察覺的亮度差異。For example, referring to Fig. 5B, the color gray scale (R, G, B) of the picture to be displayed by the pixel array 100a is (192, 64, 128), and according to the red gray scale, green gray scale, and blue gray scale The resolution ratio of (0.8,1,1) is used to drive the sub-pixels. Among them, in the 192 gray scale, the voltage difference of the sub-pixels respectively driven according to the first gamma function and the second gamma function with a resolution ratio of 0.8 is also 1.35 volts. That is, the first, fourth, seventh, and tenth voltage differences are all -1.35 volts. Therefore, the first value V1 is (-1.35*4)=-5.4 volts. Among them, at 64 gray scales, the voltage difference of the sub-pixels respectively driven according to the first gamma function and the second gamma function with a resolution ratio of 1 is 1.25 volts. That is, the second, fifth, eighth, and eleventh voltage differences are all 1.25 volts. Therefore, the second value V2 is (1.25*4)=5 volts. Moreover, in any gray scale driving the pixel pixel array 130a, the third value V3 is zero. The sum of the first value V1, the second value V2, and the third value V3 is equal to -0.4 volts (-5.4 volts + 5 volts), and its absolute value is less than 900 millivolts. In this way, the visually perceptible brightness difference of humans can be avoided.

在本案的一些實施例中，藉由調整紅色子畫素的分離度比例或調整綠色子畫素的分離度比例，使得第一數值V1與第二數值V2的總和大致上為零。In some embodiments of this case, by adjusting the separation ratio of the red sub-pixels or adjusting the separation ratio of the green sub-pixels, the sum of the first value V1 and the second value V2 is substantially zero.

第5C圖繪示根據本案的一實施例當中第3圖的畫素陣列130a依據第5A圖的查找表所產生之電壓差總和的示意圖。FIG. 5C is a schematic diagram of the sum of voltage differences generated by the pixel array 130a of FIG. 3 according to the look-up table of FIG. 5A according to an embodiment of the present application.

舉例而言，請參閱的5C圖，畫素陣列100a待顯示的畫面的色彩灰階(R,G,B)為(192,64,128)，並且依據紅色灰階、綠色灰階、藍色灰階的分離度比例(0.71, 1 ,1)來驅動子畫素。其中在192灰階，依據分離度比例為0.71的第一伽瑪函數以及第二伽瑪函數而分別驅動的子畫素的電壓差亦為1.25伏特。亦即，第一、第四、第七、第十電壓差皆為-1.25伏特。因此第一數值V1為(-1.25*4)=-5伏特。其中在64灰階，依據分離度比例為1的第一伽瑪函數以及第二伽瑪函數而分別驅動的子畫素的電壓差為1.25伏特。亦即，第二、第五、第八、第十一電壓差皆為1.25伏特。因此第二數值V2為(1.25*4)=5伏特。並且，在任一灰階驅動畫素畫素陣列130a，第三數值V3為零。第一數值V1、第二數值V2以及第三數值V3的總和大致上為零。For example, please refer to the figure 5C, the color gray scale (R, G, B) of the picture to be displayed in the pixel array 100a is (192, 64, 128), and according to the red gray scale, green gray scale, and blue gray scale The resolution ratio of (0.71, 1, 1) to drive the sub-pixels. Among them, in the 192 gray scale, the voltage difference of the sub-pixels respectively driven according to the first gamma function and the second gamma function with a separation ratio of 0.71 is also 1.25 volts. That is, the first, fourth, seventh, and tenth voltage differences are all -1.25 volts. Therefore, the first value V1 is (-1.25*4)=-5 volts. Among them, at 64 gray scales, the voltage difference of the sub-pixels respectively driven according to the first gamma function and the second gamma function with a resolution ratio of 1 is 1.25 volts. That is, the second, fifth, eighth, and eleventh voltage differences are all 1.25 volts. Therefore, the second value V2 is (1.25*4)=5 volts. Moreover, in any gray scale driving the pixel pixel array 130a, the third value V3 is zero. The sum of the first value V1, the second value V2, and the third value V3 is substantially zero.

如此一來，依據第5A圖的查找表所示的實施例，使得畫素陣列100b中的所有顏色的子畫素的電壓差總和大致上為零，以進一步改善資料訊號從第一列R1到第二列R2的變化透過寄生電容拉高或降低共用電極的電壓所造成的水平串擾。In this way, according to the embodiment shown in the look-up table in FIG. 5A, the sum of the voltage difference of all the sub-pixels of all colors in the pixel array 100b is substantially zero, so as to further improve the data signal from the first row R1 to The change of the second row R2 raises or lowers the horizontal crosstalk caused by the voltage of the common electrode through the parasitic capacitance.

在本案的另一些實施例中，如第6圖所示的實施例。第6圖繪示根據本案的實施例當中第1圖及第2圖的畫素列內所顯示之亮度所繪示的顯示裝置100b的示意圖。如第6圖所示，顯示裝置100包含複數條資料線D1~D12、複數條閘極線G1~G2、資料驅動電路110、閘極驅動電路120以及畫素陣列130b。顯示裝置100的配置與第3圖中的顯示裝置100的配置大致相同，在此不再贅述。In other embodiments of this case, such as the embodiment shown in Figure 6. FIG. 6 is a schematic diagram of the display device 100b drawn according to the brightness displayed in the pixel rows of FIG. 1 and FIG. 2 according to an embodiment of the present application. As shown in FIG. 6, the display device 100 includes a plurality of data lines D1 to D12, a plurality of gate lines G1 to G2, a data driving circuit 110, a gate driving circuit 120, and a pixel array 130b. The configuration of the display device 100 is substantially the same as the configuration of the display device 100 in FIG. 3, and will not be repeated here.

與第3圖中的畫素陣列130a相較，畫素陣列130b的不同之處在於第一群組的子畫素PH以及第二群組的子畫素PL的排列方式。第一群組PH的子畫素包含子畫素P1A、P1B、P1C、P1H、P1I、P1J、P2D、P2E、P2F、P2G、P2K、P2L，第二群組PL的子畫素包含子畫素P1D 、P1E、P1F、P1G、P1K、P1L 、P2A、P2B、P2C、P2H、P2I、P2J。Compared with the pixel array 130a in FIG. 3, the difference of the pixel array 130b lies in the arrangement of the sub-pixels PH of the first group and the sub-pixels PL of the second group. The sub-pixels of the first group PH include sub-pixels P1A, P1B, P1C, P1H, P1I, P1J, P2D, P2E, P2F, P2G, P2K, P2L, and the sub-pixels of the second group PL include sub-pixels P1D, P1E, P1F, P1G, P1K, P1L, P2A, P2B, P2C, P2H, P2I, P2J.

並且，資料驅動電路110分別經由資料線D1~D12提供給子畫素行C1~C12中的子畫素的資料訊號的極性依序為”正、負、正、負、正、負、正、負、正、負、正及負”。In addition, the polarity of the data signal provided by the data driving circuit 110 to the sub-pixels in the sub-pixel rows C1 to C12 via the data lines D1 to D12 are "positive, negative, positive, negative, positive, negative, positive, negative, respectively". , Positive, negative, positive and negative".

並且，畫素陣列130b亦可依據第4A圖或者是第5A圖所示的查找表驅動。In addition, the pixel array 130b can also be driven according to the look-up table shown in FIG. 4A or FIG. 5A.

第一群組PH的子畫素可依據第一伽瑪函數GH決定其顯示的灰階與亮度關係。相較於第一群組PH子畫素，第二群組PL的子畫素可依據亮度等級較暗的第二伽瑪函數GL決定其顯示的灰階與亮度關係。The sub-pixels of the first group PH can determine the relationship between the gray scale and the brightness of their display according to the first gamma function GH. Compared with the PH sub-pixels of the first group, the sub-pixels of the second group PL can determine the relationship between the gray scale and the brightness of the display according to the second gamma function GL with a darker brightness level.

因此，在子畫素行C1~C12的子畫素P1A~P1L的亮度相較於在相應的子畫素行C1~C12的子畫素P2A~P2L的亮度具有十二個亮度對比，這十二個亮度對比依序為亮、亮、亮、暗、暗、暗、暗、亮、亮、亮、暗及暗。Therefore, the brightness of the sub-pixels P1A~P1L in the sub-pixel rows C1~C12 has twelve brightness contrasts compared with the brightness of the sub-pixels P2A~P2L in the corresponding sub-pixel rows C1~C12. The brightness contrast is bright, bright, bright, dark, dark, dark, dark, bright, bright, bright, dark, and dark in order.

亦即，在畫素陣列130b中，十二個子畫素行C1~C12具有12個電壓差。P2A的顯示電壓減去P1A的顯示電壓為第一電壓差；P2B的顯示電壓減去P1B的顯示電壓為第二電壓差；P2C的顯示電壓減去P1C的顯示電壓為第三電壓差，依此類推，P2D~P2L的顯示電壓減去P1D~P1L的顯示電壓依序為第四電壓差至第十二電壓差。That is, in the pixel array 130b, the twelve sub-pixel rows C1 to C12 have 12 voltage differences. The display voltage of P2A minus the display voltage of P1A is the first voltage difference; the display voltage of P2B minus the display voltage of P1B is the second voltage difference; the display voltage of P2C minus the display voltage of P1C is the third voltage difference, and so on By analogy, the display voltage of P2D~P2L minus the display voltage of P1D~P1L is the fourth voltage difference to the twelfth voltage difference in order.

接著，將相同顏色子畫素行的電壓差加總，以區分紅色、藍色、綠色的子畫素在各自的灰階顯示時可能造成水平串擾的電壓差。Then, the voltage differences of the sub-pixel rows of the same color are summed to distinguish the voltage differences that may cause horizontal crosstalk when the red, blue, and green sub-pixels are displayed in their respective gray scales.

在紅色子畫素行中的電壓差的總合(第一數值V1)為第一電壓差、第四電壓差、第七電壓差以及第十電壓差的總和；在綠色子畫素行中的電壓差的總合(第二數值V2)為第二電壓差、第五電壓差、第八電壓差以及第十一電壓差的總和；在藍色子畫素行中的電壓差的總合(第三數值V3)為第三電壓差、第六電壓差、第九電壓差以及第十二電壓差的總和。The sum of the voltage differences in the red sub-pixel row (the first value V1) is the sum of the first voltage difference, the fourth voltage difference, the seventh voltage difference, and the tenth voltage difference; the voltage difference in the green sub-pixel row The sum of (the second value V2) is the sum of the second voltage difference, the fifth voltage difference, the eighth voltage difference, and the eleventh voltage difference; the sum of the voltage differences in the blue sub-pixel rows (the third value V3) is the sum of the third voltage difference, the sixth voltage difference, the ninth voltage difference, and the twelfth voltage difference.

第7圖繪示根據本案的一實施例當中第6圖的畫素陣列130b依據第5A圖的查找表所產生之電壓差總和的示意圖。FIG. 7 is a schematic diagram of the sum of voltage differences generated by the pixel array 130b in FIG. 6 according to the look-up table in FIG. 5A according to an embodiment of the present application.

請參閱第7圖，與畫素陣列130a不同的是，根據資料訊號的極性以及空間上特定的群組劃分，在畫素陣列130b中，在紅色子畫素行中的電壓差的總合(第一數值V1)為零。換而言之，在任一灰階驅動畫素陣列130b，第一數值V1為零。並且，在畫素陣列130b中，在綠色子畫素行中的電壓差的總合 (第二數值V2)為正數值，在藍色子畫素行中的電壓差的總合(第三數值V3)為負數值。Please refer to Figure 7. The difference from the pixel array 130a is that according to the polarity of the data signal and the specific group division in space, in the pixel array 130b, the sum of the voltage differences in the red sub-pixel rows (section A value V1) is zero. In other words, when the pixel array 130b is driven at any gray level, the first value V1 is zero. In addition, in the pixel array 130b, the sum of the voltage differences in the green sub-pixel row (the second value V2) is a positive value, and the sum of the voltage differences in the blue sub-pixel row (the third value V3) Is a negative value.

舉例而言，如第7圖所示，畫素陣列130b待顯示的畫面的色彩灰階(R,G,B)為(64,192,192)。在192灰階，依據第一伽瑪函數而驅動的子畫素與依據第二伽瑪函數而驅動的子畫素的電壓差為1.7伏特。並且，在任一灰階驅動畫素陣列130b，第一數值V1為零。亦即，第二、第五、第八、第十一電壓差皆為1.7伏特；第三、第六、第九、第十二電壓差皆為-1.7伏特。因此第二數值V2為(1.7*4)=6.8伏特，第三數值V3為(-1.7*4)=-6.8伏特。第一數值V1為零。第一數值V1、第二數值V2以及第三數值V3的總合大致上為零。For example, as shown in FIG. 7, the color gray scale (R, G, B) of the picture to be displayed by the pixel array 130b is (64,192,192). In the 192 gray scale, the voltage difference between the sub-pixels driven according to the first gamma function and the sub-pixels driven according to the second gamma function is 1.7 volts. Moreover, in any gray scale driving pixel array 130b, the first value V1 is zero. That is, the second, fifth, eighth, and eleventh voltage differences are all 1.7 volts; the third, sixth, ninth, and twelfth voltage differences are all -1.7 volts. Therefore, the second value V2 is (1.7*4)=6.8 volts, and the third value V3 is (-1.7*4)=-6.8 volts. The first value V1 is zero. The sum of the first value V1, the second value V2, and the third value V3 is substantially zero.

與第3圖相較，關於第6圖的畫素陣列130b的其它作動方式，大致相似於第3圖中的畫素陣列130a，在此不再贅述。Compared with FIG. 3, other operation modes of the pixel array 130b in FIG. 6 are roughly similar to those of the pixel array 130a in FIG. 3, and will not be repeated here.

綜上所述，本案的畫素陣列130a以及畫素陣列130b利用特定的群組排列方式以及依據兩個或兩個以上的伽瑪函數提供顯示電壓予不同群組，以降低側視角偏白、亮暗紋路以及水平串擾的影響。In summary, the pixel array 130a and the pixel array 130b of the present application use a specific group arrangement and according to two or more gamma functions to provide display voltages to different groups to reduce the whiteness of the side viewing angle, The influence of bright and dark lines and horizontal crosstalk.
