Abstract

The invention provides a compensation method and device for a display panel. The processing method comprises the steps of: obtaining a first gray-scale value of any sub-pixel in a target panel at a first gray scale and a second gray-scale value of any sub-pixel in the target panel at a second gray scale; acquiring position information of a target sub-pixel in a target compensation area of the target panel according to the first gray-scale value and the second gray-scale value; according to the position information of the target sub-pixel, obtaining a gray scale compensation value of a reference sub-pixel adjacent to the target sub-pixel; and obtaining the gray scale compensation value of the target sub-pixel according to the gray scale compensation value of the reference sub-pixel. The coordinates of the target sub-pixels located in the special-shaped area in the target panel are obtained through the high-gray-scale display image and the low-gray-scale display image, then the gray-scale compensation values of the sub-pixels adjacent to the target sub-pixels are obtained, accurate gray-scale compensation is conducted on the target sub-pixels through interpolation of the gray-scale compensation values of the adjacent sub-pixels, and the product quality is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel compensation method and device. Background technique [0002] Due to factors such as the driver and characteristics of the LCD panel, there will be a considerable degree of color shift difference in the white balance grayscale color performance. In order to achieve a certain degree of correctness and consistency in the color of the display, it is necessary to compensate the gray scale of the display one by one. [0003] In the existing display panel, due to the existence of rounded corners, grooves and other irregular-shaped areas in the panel, the sub-pixels located at the boundaries of the irregular-shaped areas are usually compensated by linear interpolation of the gray levels of adjacent sub-pixels. However, because the sub-pixels on one side are blocked, the gray scale of the sub-pixels on one side is an abnormal value, which causes the compensation value obtai...
