Abstract

The invention relates to a method and device for obtaining Mura compensation data, computer equipment and a storage medium. The method comprises the steps: obtaining the brightness data of a detectionframe displayed by a display panel by using a preset gray scale, wherein the detection frame includes a mixed color gray scale frame; determining luminance data of the three primary colors accordingto the luminance coefficients of the respective primary colors corresponding to the mixed colors and the luminance data; and further determining compensation data corresponding to the display panel according to the luminance data of the three primary colors. The method obtains the brightness data of the three primary colors by capturing the mixed color gray scale frame, shortens the shooting timeof a CCD camera, reduces the time cost, and solves a technical problem of low efficiency when acquiring the Mura compensation data.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method, device, computer equipment and storage medium for acquiring Mura compensation data. 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] At present, various manufacturers use CCD cameras to capture the detection pictures displayed on the display panel. Under multiple gray scales, the CCD ca...
