Abstract

The invention relates to a brightness compensation method and device of a display screen and a storage medium. The method comprises the following steps: acquiring a statistical value of historical display brightness of pixels in the display screen; and based on a preset brightness attenuation model and the statistical value of the historical display brightness, performing display brightness compensation of the display screen by adjusting the driving signal values of the sub-pixels included in the pixels. Through the method, the service life of the display screen can be prolonged, and the problem of display branding can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, in particular to a brightness compensation method and device for a display screen, and a storage medium. Background technique [0002] Currently, electronic devices with display functions (such as smart phones) mostly use organic light-emitting diodes (Organic Light-Emitting Diode, OLED) to make display screens. OLED display has the advantages of self-illumination, clear and bright, thin and light, fast response, wide viewing angle and low power consumption. [0003] The OLED display is mainly composed of a light-emitting layer and a control circuit. The light-emitting layer is prone to insufficient display brightness, such as aging due to excessive use, resulting in insufficient display brightness or burn-in. Contents of the invention [0004] The disclosure provides a brightness compensation method and device for a display screen, and a storage medium. [0005] Accordi...
