Embodiment Construction

[0025] As mentioned in the background art, in the edge area of ​​the display screen, after brightness compensation, the display effect becomes worse. The inventors found that in the edge area adjacent to the border of the display screen, if the pixels in the edge area have Mura areas caused by individual pixels being dark or not bright at all, after brightness compensation, the pixels in the edge area are always brighter , affecting the display and making it worse. After further research, the inventor found that in the process of performing corresponding brightness compensation according to the data captured by the image acquisition device, all mura areas in the display area, including the mura area in the edge area, can be detected, and the display area Compensate for all mura regions within. In fact, the resolution of the human eye is not sufficient to perceive the mura area in the edge area. The compensation for the mura area in the edge area instead emphasizes or magnifi...

Abstract

The present invention relates to a Mura compensation method, device, computer equipment and storage medium of a display screen, the display screen includes a main display area and at least one edge area adjacent to the main display area, the method includes: acquiring the The brightness data corresponding to the edge area and the main display area respectively, so as to determine the edge area and the main display area according to the brightness data respectively corresponding to the edge area and the main display area and the preset target brightness data Compensation data corresponding to the regions respectively, and then compensate the edge region and the main display region respectively. Therefore, the technical problem in the traditional technology that the same compensation is performed on the display area of ​​the display screen in the same way leads to a worse display effect is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method, device, computer equipment and storage medium for Mura compensation of a display screen. Background technique [0002] With the rapid development of video display technology, large-size, ultra-high-resolution, and ultra-narrow bezel display technologies have become the focus of competition among various panel makers. Control deviation is likely to cause poor image uniformity and Mura. Among them, Mura refers to the display unevenness of the display screen, which is caused by factors such as the level of technology and the purity of raw materials, and is a common technical problem in the field of display technology. [0003] In the traditional technology, in order to compensate for the mura phenomenon caused by defects in the production process, brightness compensation is generally used to correct the brightness of each pixel in the display screen, thereby eliminating ...
