Abstract

The present application discloses a display screen brightness correction method, device and electronic equipment. The method includes: obtaining the brightness value of each light-emitting unit of the display screen under a white screen. The light-emitting unit is obtained by dividing the backlight source of the display screen. The backlight source is Matrix backlight; according to the luminance value, determine the light-emitting unit that meets the preset condition as the target light-emitting unit; set the current value of the target light-emitting unit to correct the brightness of the display screen. In the present application, by correcting the current value of some regions of the matrix backlight, light spots or dark spots caused by the structure of the display screen can be reduced, and the consistency of the brightness of the screen can be improved, thereby improving the user's visual experience.

Description

technical field [0001] The present application belongs to the technical field of image display, and in particular relates to a display screen brightness correction method, a display screen brightness correction device, electronic equipment, and a computer-readable storage medium. Background technique [0002] When the glass cover of an ordinary display screen is exposed to direct sunlight and high-brightness lighting and other viewing conditions are not good, the clarity will be affected due to the reflection of the screen, and the picture will be deformed and distorted. In severe cases, the light reflected by the glass will also affect the human body. eyesight. The solution of using atomized polarizer and atomized cover can effectively solve the problem of poor picture quality caused by reflection. However, after replacing the glass cover with an atomized polarizer and an atomized cover, the images displayed on the display are easily affected by light interference and diff...
