Abstract

The invention discloses a compensation method and an embedded touch control display panel. The method comprises the steps: storing a gray scale brightness compensation table in a time sequence controller, and searching a gray scale brightness compensation value corresponding to the current gray scale of each pixel region in the gray scale brightness compensation table according to the current grayscale of a touch control display panel; judging whether the gray scale brightness compensation value corresponding to the current gray scale of each pixel region is equal to a preset gray scale brightness compensation value or not; adjusting the voltage of a common electrode corresponding to the corresponding pixel region when the ray scale brightness compensation value corresponding to the current gray scale of each pixel region is not equal to the preset gray scale brightness compensation value, so as to carry out the gray scale compensation for the current gray scale of the embedded touchcontrol display panel. Compared with the prior art, the method just need to store the gray scale brightness compensation value corresponding to each pixel region, and reduces the quantity of stored data, so that the data can be stored in the time sequence controller of the embedded touch control display panel. The method reduces the cost of a product while improving the display effect of the embedded touch control display panel.

Description

technical field [0001] The invention relates to the display field, in particular to a compensation method and an embedded touch display panel. Background technique [0002] Due to defects in the manufacturing process of the in-cell touch display panel, it often leads to uneven brightness and various mura (mura refers to the phenomenon that the brightness of the display panel is uneven, resulting in various traces). [0003] In order to improve the brightness uniformity of the in-cell touch display panel, the existing compensation method converts the gray scale brightness compensation value of each pixel into a corresponding voltage and loads it on the pixel electrode, so that the internal The embedded touch display panel achieves relatively consistent brightness as a whole. However, it needs to store the grayscale brightness compensation values ​​of all pixels of the in-cell touch display panel, so the in-cell touch display panel needs a large amount of storage space for st...
