Embodiment Construction

[0028] As mentioned in the background art, in the conventional technology, in areas with severe Mura, after brightness compensation, the display effect becomes worse. The inventors found that for larger-sized display panels, the distribution of Mura areas is discrete. If the luminance data corresponding to multiple Mura areas are processed in the same way to generate compensation data, the display effect of the display panel will be more abnormal after luminance compensation in areas with severe Mura than before compensation, that is, the brightness compensation leads to worse display. Effect. After research, the inventors found that the root cause of this problem is that the luminance data corresponding to the multiple mura areas in the display panel are quite different, that is, the severity of the multiple mura areas in the display panel is different. Areas of different degrees of mura require different treatments. However, in the traditional technology, the multiple mura ...

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: determining at least one Mura region in a display panel according to the brightness data of a detection frame, performing the level dividing of at least one Mura region in the display panel, and determining the compensation data of the displaypanel according to the Mura level and the brightness data of the detection frame. According to the Mura level of the Mura region in the display panel, the method can select different modes for generating more accurate compensation data, solves a technical problem of poorer display effect, caused by the employing of the same mode in the conventional technology, of the Mura severe region, and improves the display effect of the display panel.

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] In the traditional technology, in order to compensate for the mura phenomenon caused by defects in the production process, brightness compensation is gene...
