立體顯示系統Stereo display system

本發明是有關於一種顯示系統，特別是有關於一種具有均勻亮度顯示之立體顯示系統的操作。This invention relates to a display system, and more particularly to the operation of a stereoscopic display system having a uniform brightness display.

立體顯示技術由於可提供觀看者生動的立體影像，已成為現今顯示技術發展的重要方向之一。習知技術中包括空間式立體顯示技術，其原理係使顯示面板同時顯示出兩組分別供左眼及右眼觀看之畫面，並使觀看者之左眼僅接收左眼畫面，右眼僅接收右眼畫面。Stereoscopic display technology has become one of the important directions in the development of display technology today because it can provide vivid stereoscopic images of viewers. The prior art includes a spatial stereoscopic display technology, the principle of which is to enable the display panel to simultaneously display two sets of images for the left eye and the right eye, and to make the left eye of the viewer only receive the left eye image, and the right eye only receives the image. Right eye picture.

一般平面顯示系統的畫面切換頻率是60Hz。然而，立體顯示系統為了能夠分別顯示左眼和右眼觀看的畫面，就必須將畫面切換頻率提升到120Hz。在習知的技術中，當立體顯示系統工作在畫面切換頻率為120Hz的模式下時，以及液晶自身轉態速度特性，導致開啟時間及關閉時間不夠快，在立體顯示系統下造成串擾(crosstalk)的現象。為了解決此串擾現象，習知技術中可在左眼畫面和右眼畫面間插入一黑畫面改善液晶轉態關閉時間不夠快的串擾現象。為達到此目的採用降解析度方式增加畫面切換頻率至240Hz。The screen switching frequency of a general flat display system is 60 Hz. However, in order to be able to display the pictures viewed by the left eye and the right eye separately, the stereoscopic display system must raise the screen switching frequency to 120 Hz. In the prior art, when the stereoscopic display system operates in a mode in which the screen switching frequency is 120 Hz, and the characteristics of the liquid crystal's own transition state, the turn-on time and the turn-off time are not fast enough, causing crosstalk under the stereoscopic display system. The phenomenon. In order to solve this crosstalk phenomenon, a black screen can be inserted between the left-eye picture and the right-eye picture in the prior art to improve the crosstalk phenomenon that the liquid crystal transition state is not fast enough. To achieve this goal, the resolution of the screen is increased to 240 Hz using a down-resolution method.

然而，在習知的解決方法中，提供給立體顯示系統之面板上每一畫素的灰階訊號位準可能不盡相同。此時，就會造成立體顯示系統所顯示的畫面有亮度不均勻的情況發生。However, in conventional solutions, the gray level signal levels for each pixel provided to the panel of the stereoscopic display system may vary. At this time, there is a case where the brightness of the screen displayed by the stereoscopic display system is uneven.

有鑑於此，本發明提供一種立體顯示系統，可以輸出亮度均勻的立體影像。In view of this, the present invention provides a stereoscopic display system capable of outputting a stereoscopic image with uniform brightness.

本發明提供一種立體顯示系統，包括顯示面板、多個掃描線、多個資料線、多個伽瑪查找表。在此顯示面板上具有多個沿一列方向排列之畫素列，並且每一畫素列沿一行方向依序排列有多個畫素。其中，各畫素列中的畫素包括一第一組畫素和一第二組畫素，並且每一畫素包括一第一子畫素和第二子畫素。每一畫素列分別對應電連接至掃描線其中之一。而掃描線包含多個第一掃描線和多個第二掃描線交替排列，而每一第一掃描線與相臨設置的第二掃描線接收的掃描訊號具有相同的致能時間。資料線也包含多個第一資料線和多個第二資料線，並且各第一資料線和第二資料線分別電連接於對應的畫素。另外，伽瑪查找表包括第一伽瑪查找表和第二伽瑪查找表。其中，每一第一組畫素之第一子畫素電連接於第一資料線，並且第一組畫素之第二子畫素電連接於第二資料線。此外，每一第二組畫素之第一子畫素電連接於第二資料線，並且第二組畫素之第二子畫素電連接於第一資料線。第一組畫素與第二組畫素於行方向交替設置，並且於列方向交替設置。本發明會依據一控制訊號選擇第一伽瑪查找表和該第二伽瑪查找表其中之一所產生的灰階訊號傳送至對應的畫素。The present invention provides a stereoscopic display system including a display panel, a plurality of scan lines, a plurality of data lines, and a plurality of gamma lookup tables. The display panel has a plurality of pixel columns arranged in a column direction, and each pixel column has a plurality of pixels arranged in a row direction. The pixels in each pixel column include a first group of pixels and a second group of pixels, and each pixel includes a first sub-pixel and a second sub-pixel. Each pixel column is correspondingly electrically connected to one of the scan lines. The scan line includes a plurality of first scan lines and a plurality of second scan lines alternately arranged, and each of the first scan lines has the same enable time as the scan signals received by the adjacent second scan lines.

According to the invention, the gray level signal generated by one of the first gamma lookup table and the second gamma lookup table is selected to be transmitted to the corresponding pixel according to a control signal.

由於在同一顯示週期期間，提供給畫素的灰階訊號是來自相同的伽瑪查找表，因此在一顯示週期期間，左眼畫面和右眼畫面的亮度是相同的。另外，在下一顯示週期期間，會由另一個伽瑪查找表提供灰階訊號給同一位置之畫素，因此每一畫素列的亮度會被平均。如此一來，本發明之立體顯示系統就可以輸出亮度均勻的立體影像。Since the gray scale signals supplied to the pixels during the same display period are from the same gamma lookup table, the brightness of the left eye picture and the right eye picture are the same during one display period. In addition, during the next display period, the gray level signal is supplied to the pixel at the same position by another gamma lookup table, so the brightness of each pixel column is averaged. In this way, the stereoscopic display system of the present invention can output a stereoscopic image with uniform brightness.

當於下一個顯示週期之第一畫面1st frame起始時，第一列掃描線G1與第二列掃描線G2被致能，控制訊號XSFT的狀態位於第二位準，可例如是高電位H，第一組畫素之第一子畫素120a就可以接收來自第二伽瑪查找表106的灰階訊號，以B表示之，而第一組畫素之第二子畫素120b接收來自第一伽瑪查找表104的灰階訊號，以A表示之，而第二組畫素之第一子畫素130a接收來自第一伽瑪查找表104的灰階訊號，以A表示之，第二組畫素之第二子畫素130b接收來自第二伽瑪查找表106的灰階訊號，以B表示之，以此類推；當第一列掃描線G1與第二列掃描線G2被禁能，而第三列掃描線G3與第四列掃描線G4被致能時，控制訊號XSFT的狀態位於第一位準，可例如是低電位L，第一組畫素之第一子畫素120a就可以接收來自第一伽瑪查找表104的灰階訊號，以A表示之，而第一組畫素之第二子畫素120b接收來自第二伽瑪查找表106的灰階訊號，以B表示之，而第二組畫素之第一子畫素130a接收來自第二伽瑪查找表106的灰階訊號，以B表示之， 第二組畫素之第二子畫素130b接收來自第一伽瑪查找表104的灰階訊號，以A表示之，以此類推。請再搭配圖3B參照圖1，因此第一列畫素R1的第一子畫素接收的灰階訊號由左而右依序為BAABBAAB...，而第一列畫素R1的第二子畫素接收的灰階訊號由左而右依序為ABBAABBA......。When the first frame 1st frame of the next display period starts, the first column scan line G1 and the second column scan line G2 are enabled, and the state of the control signal XSFT is at the second level, which may be, for example, a high potential H. The first sub-pixel 120a of the first set of pixels can receive the gray-scale signal from the second gamma look-up table 106, denoted by B, and the second sub-pixel 120b of the first set of pixels is received from the first The grayscale signal of a gamma lookup table 104 is represented by A, and the first subpixel 130a of the second set of pixels receives the grayscale signal from the first gamma lookup table 104, denoted by A, and second The second sub-pixel 130b of the group of pixels receives the gray-scale signal from the second gamma look-up table 106, denoted by B, and so on; when the first column scan line G1 and the second column scan line G2 are disabled When the third column scan line G3 and the fourth column scan line G4 are enabled, the state of the control signal XSFT is at the first level, which may be, for example, a low potential L, the first sub-pixel 120a of the first group of pixels. It is possible to receive the gray scale signal from the first gamma lookup table 104, denoted by A, and the second subpixel 120b of the first group of pixels is received. Gamma gray signal from the second lookup table 106, and when B is, the first sub-pixel and the second set of pixel gray level of the received signal 130a from the second gamma lookup table 106 to represent the B, The second sub-pixel 130b of the second set of pixels receives the grayscale signal from the first gamma lookup table 104, denoted by A, and so on. Referring to FIG. 1 again, FIG. 3B, so that the first sub-pixel of the first column of pixels R1 receives gray-scale signals from left to right in the order of BAABBAAB..., and the second column of the first column of pixels R1. The gray-scale signals received by the pixels are sequentially from left to right for ABBAABBA.

本發明之一實施例提供於不同的顯示週期，藉由切換控制訊號XSFT於每一個不同的顯示週期具有不同的初始位準，使得毎兩個顯示週期第一組畫素120與第二組畫素130導通的伽瑪查找表不同，來提高顯示畫面的亮度均勻度。即使伽瑪查找表是用以校正灰階訊號的誤差，然由於不同的伽瑪查找表電路之間仍然存在些許的誤差值，藉由兩個顯示週期交替地切換將低電路間的誤差更能提高顯示畫面的亮度均勻度。An embodiment of the present invention provides different display periods, and the switching control signal XSFT has different initial levels for each different display period, so that the first group of pixels 120 and the second group of paintings are displayed for two display periods. The gamma lookup table in which the prime 130 is turned on is different to improve the brightness uniformity of the display screen. Even if the gamma lookup table is used to correct the error of the gray-scale signal, since there are still some error values between different gamma look-up table circuits, the error between the lower circuits can be more easily switched by alternately switching between two display periods. Improve the brightness uniformity of the display.

由以上可知，當子畫素亮度不同時，即第一伽瑪查找表104與第二伽瑪查找表106輸出的灰階訊號亮度A與B不相等，在顯示畫面下就會產生亮暗線，然後在同一顯示週期下，為了避免左右眼亮度不均，因此一顯示週期下，4個畫面(frame)其XSFT訊號波形相同，下一顯示週期中XSFT訊號波形與上一週期波形互補，利用空間上灰階電壓切換，因此每一畫素列的亮度值能夠藉由互補進行補償，而解決畫面亮暗線的問題。It can be seen from the above that when the sub-pixel brightness is different, that is, the gray level signal brightnesses A and B output by the first gamma lookup table 104 and the second gamma lookup table 106 are not equal, a bright dark line is generated under the display screen. Then, in the same display period, in order to avoid uneven brightness of the left and right eyes, the XSFT signal waveforms of the four frames are the same in one display period, and the XSFT signal waveform is complementary to the waveform of the previous period in the next display period, and the space is utilized. The upper gray scale voltage is switched, so the luminance value of each pixel column can be compensated by complementation, and the problem of bright and dark lines of the picture is solved.

在一些實施例中，資料線的個數為2M條，而掃描線的個數則是N條。因此，在這些實施例中所提供的畫面解析度，是M*N。然而，由於在本實施例中，第N列的掃描線與第N+1列掃描線會同時被致能，因此實際上的解析度則是M * N/2，其中M與N為自然數。In some embodiments, the number of data lines is 2M, and the number of scan lines is N. Therefore, the picture resolution provided in these embodiments is M*N. However, since in the present embodiment, the scan line of the Nth column and the X+1th column scan line are simultaneously enabled, the actual resolution is M * N/2, where M and N are natural numbers. .

雖然本發明已以較佳實施例揭露如上，然其並非用以限定本發明，任何熟習此技藝者，在不脫離本發明之精神和範圍 內，當可作些許之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and those skilled in the art without departing from the spirit and scope of the invention In the meantime, the scope of protection of the present invention is defined by the scope of the appended claims.
