Abstract

The present invention provides a method and a device of compensation for eliminating uneven brightness of a screen body. The problems are solved that the brightness compensation data is not accurate and the uniformity of the screen body brightness is poor. The method comprises the steps of: collecting brightness data of a screen body corresponding to different gray scales in multiple brightness modes; obtaining the brightness compensation data of the screen body corresponding to the different gray scales in the multiple brightness modes according to the collected brightness data; and fitting acompensation function of the screen body corresponding to each gray scale in different gray scales according to the obtained brightness compensation data; and calculating the brightness compensationdata in any one brightness mode according to the compensation function.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compensation method and device for eliminating uneven brightness of a screen body. Background technique [0002] Due to the complex production process of the display panel, the control is difficult, and the phenomenon of uneven brightness display is prone to occur during the production process, also known as the Mura phenomenon, that is, a block-like trace phenomenon caused by a certain area of ​​​​the panel due to the difference in display brightness. This further affects the image display quality of the screen body. [0003] Currently, mura defects are mainly eliminated through demura technology. Specifically, when the image is displayed, the brightness of the image is compensated, usually the gray scale of the pixels in the brighter area on the display screen is multiplied by a smaller brightness compensation coefficient, and the gray scale of the pixels in the darker area...
