Embodiment 1
[0043] See figure 1 , figure 1 A schematic diagram of a pixel arrangement design provided for the prior art. At present, liquid crystal display devices can adopt column inversion (column inversion) driving method and flip pixel (flip pixel) pixel arrangement design at the same time, so the arrangement method of pixels is H-stripe (horizontal stripes), and this arrangement method is used in the display If the screen needs to be turned on for a long time, the drive device will overheat. For example, when the light is turned on for 30 minutes, the measured temperatures of the same position of different COF (Chip On Film, chip-on-film) are 105.2°C, 100.4°C, 105.9°C, 108.2°C, 106.7°C.
[0044] See figure 2 , figure 2 It is a schematic flowchart of a method for optimizing pixel data provided by an embodiment of the present invention. Based on the above phenomenon, this embodiment proposes a method for optimizing pixel data. The method for optimizing pixel data may specificall...
Embodiment 2
[0066] On the basis of the first embodiment, this embodiment further describes the pixel data optimization method proposed in the first embodiment. The pixel data optimization method proposed in this embodiment is mainly explained by reducing the amplitude. This embodiment A specific implementation manner of step 4 in the first embodiment is mainly introduced.
[0067] Specifically, step 4 in Embodiment 1 may include: judging the magnitude of the initial amplitude difference and a preset threshold, where the preset threshold includes a first preset threshold and a second preset threshold, and the second preset threshold is greater than the first A preset threshold, if the initial amplitude difference is less than the first preset threshold, the initial pixel gray scale value of the pixels in n rows*M columns remains unchanged, if the initial amplitude difference is greater than the first preset threshold and less than the second preset threshold, Then, according to the initial...
Embodiment 3
[0106] Based on the first embodiment, this embodiment further describes the pixel data optimization method proposed in the first embodiment. The pixel data optimization method proposed in this embodiment is mainly described by reducing the frequency. This embodiment Another specific implementation manner of step 4 in the first embodiment is mainly introduced.
[0107] Specifically, step 4 in Embodiment 1 may include: judging the magnitude of the initial amplitude difference and a preset threshold, wherein the preset threshold includes a third preset threshold, and if the initial amplitude difference is smaller than the third preset threshold, then n rows The initial pixel grayscale value of the pixels in the M column remains unchanged. If the initial amplitude difference is greater than the third preset threshold value, the initial pixel grayscale value of the subpixel in the first row and the second row of the pixels in the n row*M column The initial pixel grayscale value of ...
