Therefore, in the kth rendering pixel, the sub-pixels on the side of the kth rendering pixel that are close to the jth rendering pixel and corresponding to the compensation rendering pixel are on the corresponding data line. The data voltage is actually composed of two parts: one is the data voltage required for the display of the kth rendering pixel itself, and the other is the data voltage allocated according to the above allocation conditions when it is borrowed by the jth rendering pixel.
