Abstract

The present invention relates to a Mura compensation method, device and computer equipment for a curved display screen. The display area of ​​the curved display screen includes a curved area and a plane area; according to the brightness data corresponding to the curved surface area and the flat area respectively and the preset target brightness data, determine the compensation data corresponding to the curved surface area and the flat area respectively; according to the curved surface area and the flat area The compensation data corresponding to the planar regions are respectively compensated for the curved surface region and the planar region. By obtaining the luminance data corresponding to the curved surface area and the flat area respectively, the curved surface area and the flat area are respectively compensated, and the display abnormality caused by directly using the luminance data for compensation in the traditional technology is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method, device and computer equipment for Mura compensation of curved display screens. Background technique [0002] With the rapid development of video display technology, large-size, ultra-high-resolution, and ultra-narrow bezel display technology has become the focus of competition among various panel makers. However, as the size increases, the difficulty in process control of display panels increases. Control deviation is likely to cause poor image uniformity and Mura. Among them, Mura refers to the display unevenness of the display panel, 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, each manufacturer uses a CCD camera to capture the detection picture displayed on the display panel. Under multiple gray scales, the thr...
