Problems solved by technology

[0004] The current peak luminance algorithm determines the final luminance based on the sum of the average picture luminance (APL) of the display area. However, due to the large differences in the characteristics of OLED materials of different colors, the final display luminance will be limited by the worst efficiency. material, resulting in less than perfect contrast

Abstract

The embodiment of the invention discloses a display compensation method, a display compensation device, a display panel and a storage medium. The method comprises the steps of calculating an average sub-pixel brightness proportion of sub-pixels of each color in a to-be-displayed image; calculating to obtain a brightness gain value under a preset current according to the average sub-pixel brightness proportion of each color sub-pixel and the brightness current of each color sub-pixel; and calculating the peak brightness of each sub-pixel in the to-be-displayed image according to the brightnessgain value. And the highest display contrast is ensured to be achieved within the available range of power consumption.

Description

technical field [0001] This article relates to the technical field of displays, in particular to a display compensation method, a display compensation device, a display panel and a storage medium. Background technique [0002] As a current-mode light-emitting device, electroluminescent elements have been increasingly used in display panels. Due to its self-luminous characteristics, electroluminescent display panels do not require a backlight source, and have the advantages of high contrast, thin thickness, wide viewing angle, fast response, bendable, simple structure and manufacturing process, etc., so electroluminescent display panels have gradually become the next A generation of mainstream display panels. Generally speaking, a pixel circuit includes a display unit (such as a liquid crystal display (LCD), an organic light-emitting diode (OLED) or other display units), a thin film transistor (Thin Film Transistor, TFT) and a storage capacitor (Capacitance). The wave switc...
