Abstract

The invention provides an optical compensation method and device for a display screen, a storage medium and electronic equipment. The method comprises the steps of obtaining the refreshing time of a to-be-compensated screen; adjusting the exposure time to N times of the refresh time, wherein N is a positive integer; and sending the exposure time to a camera of the optical compensation equipment, so that the camera shoots the to-be-compensated screen according to the exposure time. According to the invention, the exposure time of the camera is adjusted to be integer multiples of the refreshingtime of one frame of the screen, so that all pixel areas of the whole screen are refreshed completely once or several times within the exposure time of the camera, the brightness accumulation conditions of all pixel areas are the same, the situation that light and shade boundaries exist in the original image due to screen refreshing is avoided, and then the split screen phenomenon of the screen display effect after optical compensation is conducted on the original image is avoided.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to an optical compensation method, device, storage medium and electronic equipment for a display screen. Background technique [0002] In the OLED screen manufacturing industry, each screen is composed of millions of small pixel circuits. Due to the purity of the luminescent material and the fineness of the manufacturing process, even in the same screen, there will be uneven display brightness. . Optical compensation technology (Demura) is a technology to compensate the brightness deviation (mura) caused by the screen mechanism / process and other reasons. It mainly obtains the brightness information of each pixel in the display screen by taking pictures, and calculates the compensation data accordingly. , apply the compensation data to the picture currently displayed on the display screen, so as to realize the adjustment of the display effect of the display screen.
