Abstract

The present invention provides a backlight compensation method, device, system and storage medium. The method includes: performing brightness compensation on a plurality of mini-LEDs in a backlight module, the plurality of mini-LEDs including M rows and N columns, M and N are both positive integers greater than 1, and controlling the brightness of the backlight module by obtaining , and obtain the row compensation value corresponding to each row of mini LEDs and the column compensation value corresponding to each column of mini LEDs, and compensate the mini LEDs in each row and column according to the row compensation value and column compensation value. According to the control signal after compensation, the brightness of the backlight module is controlled according to the compensated control signal, so as to realize brightness compensation without changing the structure of the backlight module, reduce the production time and cost of the backlight module, and use the row and column as the basic unit Compensation can not only be corrected in a wide area, but also can reduce the amount of data storage and data read, and improve the control efficiency.

Description

technical field [0001] The present invention relates to backlight compensation technology, and in particular, to a backlight compensation method, device, system and storage medium. Background technique [0002] A backlight unit (BLU for short) is a light source located behind the liquid crystal display, and its lighting effect will directly affect the visual effect of the liquid crystal display module. A backlight module in the prior art may include a plurality of direct type mini-LEDs. Since there are many mini LEDs as light sources in the backlight module, uneven brightness of the mini LEDs may occur. [0003] At present, the problem of uneven brightness of mini LEDs can be solved by changing the structure of the film or reflector. However, this method will cause the problems of longer manufacturing time and higher cost of the backlight module. SUMMARY OF THE INVENTION [0004] The present invention provides a backlight compensation method, equipment, system and stora...
