The technology of display has been developing rapidly. Modern displays have been able to express the brightness and color changes of the physical world quite accurately. However, in the case of a single pixel with a sub-pixel of red, green and blue, the two primary colors When the pixel changes the color gradation and the other primary color sub-pixel is a fixed color gradation, the high gradation and low gradation in the sub-pixel of the fixed gradation will not be changed due to the change of the other two sub-pixel gradations. Different combinations of changes, for example, the first three shades of red, green, and blue sub-pixels are (160, 120, 100), and the gradation of the blue primary sub-pixels corresponds to the high gradation The low gradation system is (137, 30). In this case, if the gradation of the blue primary sub-pixel is fixed at 100, the gradation of the three sub-pixels of red, green, and blue is adjusted to (192, 128, 100), according to the modified gamma curve, it can be found that the high gradation and low gradation of the gradation of the blue primary sub-pixel are still maintained (137, 30), that is, in the conventional In the display, the color gradation of each primary sub-pixel does not follow the other sub-pictures in the system. Gradation changes generating mutual influence. Therefore, the color coordination of the overall image may be made poor, and when calculating the gradation combination of different sub-pixels, the range of the combined solution obtained has a small elastic space.

The third picture is a picture with red, green and blue. Schematic diagram of the color management system, in the display system with red pixel 10, green pixel 12, blue pixel 14 three pixels, the bright area of each pixel 10, 12, 14 The ratio of the areas 102, 122, and 142 to the dark area 104, 124, and 144 is one to one. When the target levels of the red pixel 10, the green pixel 12, and the blue pixel 14 are set to (160, 128, 96), in order to enable these pixels 10, 12, 14 to exhibit better color coordination under the target color gradation, each pixel 10, 12, 14 under its target gradation, due to different viewing angles, For example, under the condition of looking at the viewing angle and the side viewing angle of 60 degrees, a plurality of different gray scale combinations can be derived, and after the operation is returned by the driving method provided by the present invention, each pixel can be made 10, 12, 14 Under the condition of looking at the angle of view and viewing the angle of view on the 60 degree side, an optimal positive side view color gradation solution is obtained. The following is an example of the actual operation flow. First, the target of the blue pixel 14 is first The color gradation is fixed at 96. At this time, the possible viewing angle of the red pixel 10 and the color gradation group of the 60 degree side viewing angle are set. In combination, or a combination of high gradation 102 and low gradation 104, there are (198, 99), (167, 153), (180, 136), etc., and the possibility of green pixel 12 The combination of the viewing angle and the color gradation of the 60 degree side viewing angle, or a combination of the high gradation 122 and the low gradation 124, is (130, 126), (173, 0), (171, 29). And so on; then, based on the combination of the gradation of one set of red pixels 10 calculated above, for example, the high gradation 102 and the low gradation 104 of the fixed red pixel 10 are (167, 153). Under the condition of the above, the green pixel 12 and the blue pixel 14 are again calculated under various conditions corresponding to the combination of the color gradations, and the green pixel 12 possible viewing angle and the 60 degree side viewing angle are obtained. The gradation combination has (130, 126), (173, 0), (171, 29), etc., and the blue pixel 14 possible viewing angle and 60 degree side viewing angle gradation combination There are (97, 95), (104, 88), (134, 7), etc.; and then, based on the above-mentioned calculation of a set of green pixel 12 color scale combination as a benchmark, for example, fixed green The high gradation 122 and the low gradation 124 of the pixel 12 are (173, 0) Next, calculate the various color gradation combinations that the red pixel 10 and the blue pixel 14 may hold under the corresponding conditions, and obtain the possible color viewing combination of the red pixel 10 and the 60 degree side viewing angle. There are (198, 99), (167, 153), (180, 136), etc., while the blue pixel 14 may look at the angle of view with 60 The color gradation combination of the degree of view is (97, 95), (104, 88), (134, 7), etc.; and then, one of the blue pixels 14 calculated by the above is calculated. The gradation combination is used as a reference. For example, under the condition that the high gradation 142 of the fixed blue pixel 14 and the low gradation 144 are (104, 88), the red pixel 10 and the green pixel 12 are calculated again corresponding to this. The various color gradation combinations that may be established under the condition, and the possible gradation of the red pixel 10 and the color gradation of the 60 degree side viewing angle are (198, 99), (167, 153), (180, 136). ...and so on, while the green pixel 12 possible viewing angle and the 60 degree side viewing angle combination are (130, 126), (173, 0), (171, 29), etc. And after repeating the above operation under the condition that the gradation combination of one of the pixels 10, 12, and 14 is used as a reference, the red pixel 10, the green pixel 12, and the blue pixel can be used. The target gradation of the three pixels of 14 is set at (160, 128, 96), so that each of the pixels 10, 12, and 14 can obtain one of the best positive side gradation solutions corresponding thereto.

In addition, when the target color gradation of the three pixels of red, green, and blue is converted from (160, 128, 96) to (192, 120, 96), based on the driving method provided by the present invention, although blue The target color scale of the pixel is still set to 96, but since the target color gradation of the red pixel and the green pixel in this case is different from the original set value, the red pixel and the green pixel are The gradation combination solution is also different from the solution provided above, and it is obvious that the blue texel corresponding to the red pixel whose target gradation is set to 192 and the green pixel whose target gradation is set to 120 corresponds to each other. The gradation combination solution must be different from the gradation combination solution obtained in the previous paragraph, so that each pixel can also use different combinations of high gradation and low gradation when the other gradation changes in the target gradation. Achieve better display quality.
