顯示裝置Display device

本發明係相關於顯示裝置，尤指一種具有點(dot)排列像素結構以及可應用行反轉(column inversion)驅動方式之顯示裝置。The present invention relates to a display device, and more particularly to a display device having a dot array pixel structure and a column inversion driving method.

一般的顯示裝置，例如一般市面上常見的液晶顯示器(liquid crystal display，LCD)，其為了呈現不同的灰階效果並維持顯示裝置的運作效能，每一像素均需要應用不停變換極性的訊號來加以驅動。對於一般應用圖框反轉(frame inversion)驅動方式的顯示裝置而言，由於每次畫面更新都會伴隨著全面板驅動訊號的極性反轉，此一類型的顯示裝置往往會有較嚴重的閃爍(flicker)現象。而一般大尺寸的顯示裝置會傾向應用點反轉(dot inversion)或是行反轉(column inversion)來作為驅動方式。點反轉驅動代表每一相鄰畫素驅動電壓極性皆不同，請參照第1圖，其為應用點反轉驅動方式之一習知顯示面板的操作示意圖。在第1圖中，每一方格均代表一像素單元，而每一方格中由雙引號所標示的符號即代表了該方格代表之一像素單元所接收之訊號極性。由第1圖可知，各個像素單元會依其接收之訊號極性交錯(zigzag)排列。然而，由於相鄰的像素均需要接收不停變化且極性相反的驅動訊號，連結兩相鄰像素的同一條資料線也因此需要不停地變化其所乘載的驅動訊號，因而消耗大量的電力。另一方面來說，行反轉驅動代表同一行的所有像素均採用相同之驅動電壓極性，而相鄰之一行的所有像素則均採用另一極性，如此一來，同一條資料線上所乘載之驅動訊號所需要變化的頻率便可大量減少，是故能達到省電的效果。A general display device, such as a liquid crystal display (LCD) commonly used in the market, in order to present different gray scale effects and maintain the performance of the display device, each pixel needs to apply a signal that constantly changes polarity. Drive it. For a display device that generally uses a frame inversion driving method, since each screen update is accompanied by a polarity inversion of the full-board driving signal, this type of display device tends to have more severe flicker ( Flicker) phenomenon. Generally, a large-sized display device tends to use dot inversion or column inversion as a driving method. The dot inversion driving means that the polarity of each adjacent pixel driving voltage is different. Please refer to FIG. 1 , which is an operation diagram of a conventional display panel which is one of the application point inversion driving modes. In Fig. 1, each square represents a pixel unit, and the symbol indicated by double quotation marks in each square represents the polarity of the signal received by one of the pixel units. As can be seen from Fig. 1, each pixel unit is arranged in a zigzag manner according to the received signal polarity. However, since adjacent pixels need to receive driving signals with constant changes and opposite polarities, the same data line connecting two adjacent pixels also needs to continuously change the driving signals that are carried by the driving signals, thereby consuming a large amount of power. . On the other hand, the row inversion drive represents the same drive voltage polarity for all pixels in the same row, and all pixels in one adjacent row use the other polarity, so that the same data line is loaded. The frequency required to change the driving signal can be greatly reduced, so that the power saving effect can be achieved.

不同於液晶顯示器，電泳顯示器(Electro-Phoretic Display，EPD)是應用脈寬調變(pulse width modulation)的方式，來調整驅動時間以決定其所顯示的灰階效果，因此，電泳顯示灰階驅動方法需要考慮時間、次數、電壓、時序等問題，尤其是色階之間轉換驅動以及溫度補償機制等，以達到較佳的影像對比與色階顯示穩定性，所以往往需要應用特定的驅動訊號波形來達到特定的灰階效果。一般電泳顯示器常見的驅動方法是將不同的驅動方法儲存在對照表(lookup table)中，其中的每一驅動方法分別具有數個黑白閃動週期，依據不同之驅動方法來將每一像素結構預先重置至全黑或全白，再調整至預定的灰階值，然而，依據不同方法所驅動的像素結構，會分別在照光後呈現不同的顯示品質(分別會變得較白或是較黑)，是故在設計電泳顯示器時，通常會分別將重置至全黑或全白的像素結構交錯設置，以便經過長時間的日照後，應用不同驅動方式所產生的不同亮度變化可以相互抵消，進而保持原先預定的灰階值。Unlike liquid crystal displays, Electro-Phoretic Display (EPD) is a method of applying pulse width modulation to adjust the driving time to determine the gray scale effect displayed. Therefore, the electrophoretic display gray scale drive The method needs to consider the time, the number of times, the voltage, the timing, etc., especially the conversion drive between the color gradation and the temperature compensation mechanism, in order to achieve better image contrast and gradation display stability, so it is often necessary to apply a specific driving signal waveform. To achieve a specific grayscale effect. A common driving method for an electrophoretic display is to store different driving methods in a lookup table, each of which has several black and white flashing periods, and each pixel structure is pre-arranged according to different driving methods. Reset to all black or all white, and then adjust to the predetermined grayscale value. However, the pixel structure driven by different methods will display different display qualities after illumination (each will become whiter or darker). Therefore, when designing an electrophoretic display, the pixel structures reset to black or white are usually alternately arranged, so that after a long period of sunshine, different brightness changes generated by applying different driving modes can cancel each other out. In turn, the original predetermined grayscale value is maintained.

為了解決上述的問題，本發明的目的之一在於提供一種具有點(dot)排列像素結構以及可應用行反轉(column inversion)驅動方式之顯示裝置。In order to solve the above problems, it is an object of the present invention to provide a display device having a dot arrangement pixel structure and a column inversion driving method.

本發明所提出的顯示裝置可可應用同一資料線以同一極性或相同驅動方法來對其所連結的畫素單元加以驅動，以達到省電或簡化資料處理的效果。The display device proposed by the present invention can apply the same data line to drive the connected pixel units with the same polarity or the same driving method to achieve power saving or simplified data processing.

請參照第2圖，其為應用第三代半訊號源驅動(half source driving 3，HSD 3)技術之一顯示裝置200的部分示意圖，為了方便解說，第2圖僅繪示了顯示裝置200中的部分元件。顯示裝置100包含有複數個像素單元210、220、開關元件230、資料線D1、D2以及複數條閘極線G1、G2、G3，其中像素單元210以及220又分別包含有發光元件211與開關元件212以及發光元件221與開關元件222。開關元件211、212可應用薄膜電晶體(thin film transistor，TFT)來加以實現，而閘極線G1、G2、G3分別在橫向方向上傳送閘極訊號VG1、VG2、VG3，資料線D1則是在縱向方向上傳送資料訊號VD1。如同第2圖所示，顯示裝置中每一資料線可提供資料訊號給兩像素單元(例如，資料線D1傳送資料訊號VD1給像素單元210、220)，因此可減少資料線的數量為原本的一半，此外，每一資料訊號在傳送至預定的像素單元前，均需要經過兩個開關元件(例如，資料訊號VD1會先經過開關元件230、212，才會抵達像素單元210)，是故具有較佳的漏電流保護(current leakage protection)機制。然而，由於每一資料線均提供資料訊號給兩像素單元，在顯示裝置200的每兩條資料線之間，左右相鄰的兩像素單元會在同時段接收同極性的驅動訊號，例如，在資料線D1與D2之間，像素單元210、220會一同接收來自資料線D1的資料訊號VD1，請配合第2圖來參照第3圖，第3圖為應用第三代半訊號源驅動方式之一習知顯示面板的操作示意圖。由第3圖可知，應用了第三代半訊號源驅動方式的顯示裝置200，其像素的排列方式與點反轉驅動顯示面板相似，但是以兩個像素單元為一基本單位進行極性反轉，因此，相較於習知的點反轉驅動顯示面板，顯示裝置200雖具有許多的優勢，例如較少的資料線架構以及省電等優點，但其本身所具有的雙點(two dot)排列像素結構卻可能會伴隨著較嚴重的閃爍以及模糊(mura)的視覺效果，此 外，雙點排列像素結構亦會限制了顯示裝置200的解析度高低。Please refer to FIG. 2 , which is a partial schematic diagram of a display device 200 using one of the third generation half source driving 3 (HSD 3) technologies. For convenience of explanation, FIG. 2 only shows the display device 200. Some of the components. The display device 100 includes a plurality of pixel units 210 and 220, a switching element 230, data lines D1 and D2, and a plurality of gate lines G1, G2 and G3, wherein the pixel units 210 and 220 respectively include a light-emitting element 211 and a switching element. 212 and the light-emitting element 221 and the switching element 222. The switching elements 211 and 212 can be implemented by using a thin film transistor (TFT), and the gate lines G1, G2, and G3 respectively transmit the gate signals VG1, VG2, and VG3 in the lateral direction, and the data line D1 is The data signal VD1 is transmitted in the longitudinal direction. As shown in FIG. 2, each data line in the display device can provide a data signal to the two pixel units (for example, the data line D1 transmits the data signal VD1 to the pixel units 210, 220), thereby reducing the number of data lines as originally. In addition, each data signal needs to pass through two switching elements before being transmitted to a predetermined pixel unit (for example, the data signal VD1 will pass through the switching elements 230, 212 before reaching the pixel unit 210), so that A preferred current leakage protection mechanism. However, since each data line provides a data signal to the two pixel units, between each two data lines of the display device 200, the two adjacent pixel units receive the same polarity driving signal at the same time, for example, Between the data lines D1 and D2, the pixel units 210 and 220 receive the data signal VD1 from the data line D1 together. Please refer to FIG. 3 in conjunction with FIG. 2, and FIG. 3 shows the application of the third generation semi-signal source driving method. A schematic diagram of the operation of a conventional display panel. As can be seen from FIG. 3, the display device 200 to which the third-generation semi-signal source driving method is applied has a pixel arrangement similar to that of the dot inversion driving display panel, but the polarity is reversed by using two pixel units as a basic unit. Therefore, the display device 200 has many advantages, such as less data line architecture and power saving, compared to the conventional dot inversion driving display panel, but has its own two dot arrangement. The pixel structure may be accompanied by more severe flicker and mura visual effects. In addition, the two-dot arrangement pixel structure also limits the resolution of the display device 200.

請參照第4圖，其為依據本發明之一實施例所實現之顯示裝置400的部分示意圖。為了簡明起見，第4圖僅繪示了顯示裝置400中與本發明技術內容有關的部分元件。顯示裝置400(例如：一液晶顯示器(liquid crystal display，LCD)或是一電泳顯示器(Electro-Phoretic Display，EPD))包含有一第一閘極線G1、一第二閘極線G2、一第三閘極線G3、第一像素單元410、一第二像素單元420、一開關電路430以及一第一資料線D1。像素單元410以及420又分別包含有發光元件411與開關元件412以及發光元件421與開關元件422，此外，閘極線G1、G2、G3彼此相鄰且依序設置，並分別在橫向方向上傳送閘極訊號VG1、VG2、VG3，而資料線D1則是在縱向方向上傳送資料訊號VD1。請注意，在本發明的實施例中，開關元件均是以薄膜電晶體(thin film transistor，TFT)來加以實現，然而，這並非用來限制本發明之範圍，只要具有開關功能且可整合於顯示裝置內之元件，均可應用於本發明之中。Please refer to FIG. 4, which is a partial schematic diagram of a display device 400 implemented in accordance with an embodiment of the present invention. For the sake of brevity, FIG. 4 only shows some of the elements of the display device 400 that are relevant to the technical content of the present invention. The display device 400 (for example, a liquid crystal display (LCD) or an electro-optical display (EPD)) includes a first gate line G1, a second gate line G2, and a third The gate line G3, the first pixel unit 410, a second pixel unit 420, a switch circuit 430, and a first data line D1. The pixel units 410 and 420 further include a light-emitting element 411 and a switching element 412, and a light-emitting element 421 and a switching element 422, respectively. Further, the gate lines G1, G2, and G3 are adjacent to each other and sequentially disposed, and are respectively transmitted in the lateral direction. The gate signals VG1, VG2, and VG3, and the data line D1 transmit the data signal VD1 in the longitudinal direction. Please note that in the embodiments of the present invention, the switching elements are all implemented by thin film transistors (TFTs), however, this is not intended to limit the scope of the present invention, as long as it has a switching function and can be integrated in The components within the display device can be used in the present invention.

顯示裝置400中的像素單元410以及像素單元420之驅動方式與顯示裝置200中的像素單元210以及像素單元220相近，均是經由二個閘極訊號來決定是否將資料訊號傳送給一像素單元。例如經由閘極訊號VG1、VG3來決定是否將資料訊號傳送給像素單元410，以及經由閘極訊號VG2、VG3來決定是否將資料訊號傳送給像素單元420，然而，顯示裝置400與顯示裝置200之間最大的差異在於， 顯示裝置400中的像素單元410以及420是交錯(zigzag)的方式所排列的，如第4圖所示，像素單元410與像素單元420是分別配置在相鄰的兩像素行(pixel column)以及相鄰的兩像素排(pixel row)上，然而，這並非用來限制本發明的範圍，第一像素單元410與第二像素單元420亦可設置於相隔兩列以上之像素列以及相隔兩排以上之像素排中，凡是將第一像素單元410與第二像素單元420以交叉排設置在不同的兩像素行以及不同之兩像素列中的結構，均屬於本發明之範疇。The driving manners of the pixel unit 410 and the pixel unit 420 in the display device 400 are similar to those of the pixel unit 210 and the pixel unit 220 in the display device 200. Both of the gate signals are used to determine whether to transmit the data signal to a pixel unit. For example, whether to transmit the data signal to the pixel unit 410 via the gate signals VG1 and VG3, and whether to transmit the data signal to the pixel unit 420 via the gate signals VG2 and VG3, however, the display device 400 and the display device 200 The biggest difference is that The pixel units 410 and 420 in the display device 400 are arranged in a zigzag manner. As shown in FIG. 4, the pixel unit 410 and the pixel unit 420 are respectively disposed in adjacent pixel columns (pixel columns) and Adjacent to two pixel rows, however, this is not intended to limit the scope of the present invention. The first pixel unit 410 and the second pixel unit 420 may also be disposed in two or more columns of pixels and separated by two rows. In the above pixel row, any structure in which the first pixel unit 410 and the second pixel unit 420 are arranged in a cross row in two different pixel rows and two different pixel columns is within the scope of the present invention.

請再參照第5圖來進一步了解顯示裝置400的運作，第5圖為依據本發明之一實施例應用一特定波形之閘極訊號來驅動顯示裝置400中部分像素單元的示意圖。為了簡明起見，第5圖中僅標示了閘極線G1~G6、資料線D1~D3、像素單元A1~A8以及B0~B7。閘極線G1~G6分別用來依序傳遞具有該特定波形之閘極訊號VG1~VG6，資料線D1依據閘極訊號VG1~VG6，經由相對應之開關元件來驅動像素單元B0、B1、B4以及B5，資料線D2則同樣經由相對應之開關元件來驅動像素單元A1~A8，而資料線D3亦經由相對應之開關元件來驅動像素單元B2、B3、B6以及B7。Please refer to FIG. 5 to further understand the operation of the display device 400. FIG. 5 is a schematic diagram of driving a portion of the pixel unit in the display device 400 by applying a gate signal of a specific waveform according to an embodiment of the present invention. For the sake of brevity, only the gate lines G1 to G6, the data lines D1 to D3, the pixel units A1 to A8, and B0 to B7 are indicated in FIG. The gate lines G1~G6 are respectively used to sequentially transmit the gate signals VG1~VG6 having the specific waveform, and the data line D1 drives the pixel units B0, B1, B4 via the corresponding switching elements according to the gate signals VG1~VG6. And B5, the data line D2 also drives the pixel units A1~A8 via the corresponding switching elements, and the data line D3 also drives the pixel units B2, B3, B6 and B7 via the corresponding switching elements.

請再配合第5圖來參照第6圖，第6圖為第4圖所示之顯示裝置400中閘極訊號VG1~VG6的時序示意圖。由第6圖可知，閘極訊號VG1~VG6訊號係為具有同一時間位移的波形訊號(亦即，第三代半訊號源驅動(half source driving 3，HSD3))，當僅有閘極訊號VG1 與VG2為高電位時，串接於資料線D1與像素單元B0之間的兩個開關元件均會處理通路(導通)狀態，資料訊號VD1於是可順利驅動像素單元B0，而在下一個時序中，僅有閘極訊號VG1與VG3為高電位，串接於資料線D1與像素單元B1之間的兩個開關元件以及串接於資料線D2與像素單元A1之間的兩個開關元件均會處於通路(導通)狀態，資料訊號VD1與VD2於是可分別驅動像素單元B1與像素單元A1，以此類推。如此一來，像素單元B0、A1與B1、A2與B2、A3與B3、A4與B4、A5與B5、A6與B6、A7與B7、A8便可依序順利被驅動。Referring to FIG. 6 again, FIG. 6 is a timing diagram of the gate signals VG1 VG VG6 in the display device 400 shown in FIG. 4 . As can be seen from Figure 6, the gate signals VG1~VG6 are waveform signals with the same time shift (that is, the third generation of half source driving 3 (HSD3)), when only the gate signal VG1 When the VG2 is at a high potential, the two switching elements connected in series between the data line D1 and the pixel unit B0 will process the path (on) state, and the data signal VD1 can smoothly drive the pixel unit B0, and in the next timing, Only the gate signals VG1 and VG3 are at a high potential, and the two switching elements connected in series between the data line D1 and the pixel unit B1 and the two switching elements connected in series between the data line D2 and the pixel unit A1 are at In the path (on) state, the data signals VD1 and VD2 can then drive the pixel unit B1 and the pixel unit A1, and so on. In this way, the pixel units B0, A1 and B1, A2 and B2, A3 and B3, A4 and B4, A5 and B5, A6 and B6, A7 and B7, and A8 can be smoothly driven in order.

請再參照第7圖，第7圖為依據本發明之一實施例來驅動顯示裝置400中部分像素單元的操作示意圖。由第7圖可知，每一像素單元與其相鄰之像素單元會由相鄰而不同的資料線來加以驅動，像素單元A1~A8與像素單元B0~B7彼此交錯配置，而像素單元A1~A8是由資料線D2所驅動，像素單元B0~B7則是由與資料線D2相鄰的資料線D1與D3所驅動，隨著時序的推進，顯示裝置400會依據閘極訊號VG1~VG6來交錯驅動像素單元A1~A8與像素單元B0~B7，而在驅動顯示裝置400的操作中，可依循行反轉的驅動方式來分別變換資料線D1、D2與D3乘載的訊號極性，以達到省電的效果，同時並可保持單點(dot)排列結構，避免模糊(mura)與閃爍(flicker)現象的發生。舉例來說，請參照第8圖，第8圖為依據本發明之一實施例以行反轉驅動方式來驅動顯示裝置400中部分像素單元的操作示意圖。當資料線D2乘載正極性訊號”+”時，相鄰的資料 線D1與D3便會乘載著負極性訊號”-”，由於資料線D2僅用以驅動像素單元A1~A8，而資料線D1與D3僅用以驅動B0~B7，是故最後像素單元A1~A8與像素單元B0~B7便會呈現與點反轉的像素結構相同之正負極性交錯的單點排列結構。Referring to FIG. 7, FIG. 7 is a schematic diagram showing the operation of driving a part of the pixel units in the display device 400 according to an embodiment of the present invention. As can be seen from FIG. 7, each pixel unit and its adjacent pixel unit are driven by adjacent and different data lines, and pixel units A1~A8 and pixel units B0~B7 are alternately arranged with each other, and pixel units A1~A8 are arranged. It is driven by the data line D2, and the pixel units B0~B7 are driven by the data lines D1 and D3 adjacent to the data line D2. As the timing advances, the display device 400 is interleaved according to the gate signals VG1~VG6. The pixel units A1 to A8 and the pixel units B0 to B7 are driven, and in the operation of driving the display device 400, the signal polarity of the data lines D1, D2 and D3 can be respectively converted according to the driving method of the line inversion to achieve the province. The effect of electricity, while maintaining a dot arrangement, avoids the occurrence of mura and flicker. For example, please refer to FIG. 8. FIG. 8 is a schematic diagram showing the operation of driving a part of pixel units in the display device 400 in a row inversion driving manner according to an embodiment of the present invention. When the data line D2 is loaded with the positive polarity signal "+", the adjacent data Lines D1 and D3 will carry the negative polarity signal "-", because data line D2 is only used to drive pixel units A1~A8, and data lines D1 and D3 are only used to drive B0~B7, so the last pixel unit A1 ~A8 and pixel units B0~B7 will exhibit the same positive and negative polarity staggered single-point arrangement structure as the dot-reversed pixel structure.

綜上所述，本發明所提出的顯示裝置可以行反轉驅動來運作，並同時具有點排列的像素結構，不但可以應用較簡單的架構達到省電的目的，亦可保有點排列像素結構的優點，避免閃爍以及模糊的現象。In summary, the display device of the present invention can be operated by inversion driving, and has a dot-arrayed pixel structure, which can not only use a simpler architecture to achieve power saving, but also preserve a pixel structure. Advantages, avoiding flicker and blurring.
