Problems solved by technology
[0003] OLED (Organic Light-Emitting Diode) curved surface display due to the influence of process stability, technology maturity, etc., there are often mura defects in the display panel, that is, the actual brightness of some pixels is darker or brighter than the theoretical brightness that should be displayed.
Generally, the method of optical compensation can be used to improve the product yield. However, when performing optical compensation on foldable curved displays, the compensation of the curved surface becomes a major difficulty. Currently, there is no mura external compensation equipment and solutions for curved displays. put forward

The invention provides a display screen mura compensation system and method. The display screen mura compensation system comprises a fixing base which is used for fixing a display screen; an image acquisition device which is used for acquiring the image data under the light emitting state of the display screen; and a data processing device which is connected with the fixing base and the image acquisition device and used for receiving the image data and performing analytical calculation so as to obtain the mura compensation data of the display screen. Display screen mura compensation can be realized by the display screen mura compensation system and method.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to a mura compensation system and method for a display screen. Background technique [0002] 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. 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. The control deviation will easily lead to poor image uniformity and mura, which will directly cause a decrease in the yield rate of the display panel and cause losses to the manufacturer. Although the probability of occurrence of the mura phenomenon can be reduced by improvin...
