Problems solved by technology

However, as the panel wire length becomes longer and longer, the wire resistance also increases
Inevitably, the power supply voltage will produce a voltage drop (IR Drop) on the wire, and the resistance value of the wire makes each pixel circuit obtain a different power supply voltage, so that under the same data signal voltage input, different pixels have different Current and brightness output, resulting in uneven display brightness of the entire panel, affecting the display quality of the panel

Abstract

The present application provides a grayscale compensation method, device and system for a display panel. The method includes: acquiring the actual brightness value in the brightness parameters of each display block in the display panel; Relationship, and the actual brightness value of each display block, determine the compensated gray scale value of each display block; determine the corresponding display gray scale value of each display block according to the compensated gray scale value, to display the gray scale value is displayed. The gray scale compensation method of the display panel provided by this application is based on the actual brightness value of each display block on the display panel, the corresponding relationship between the compensated gray scale value and the brightness parameter, and the actual brightness value of each display block. The gray scale of each display block is compensated, and the brightness output of different pixels is reasonably adjusted, so that under the same data signal voltage input, the display brightness of the entire panel tends to be uniform, and the actual display quality of the panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a grayscale compensation method, device and system for a display panel. Background technique [0002] OLED (Organic Light Emitting Display, organic light-emitting diode) display device has the advantages of self-illumination, fast response, high contrast, high color gamut, wide viewing angle, etc., and can also be bent. Compared with LCD (Liquid Crystal Display, liquid crystal display) , OLED does not require a backlight, and can also achieve ultra-thin. [0003] With the advancement of the times and technology, large-size, high-resolution AMOLED (Active-Matrix Organic Light-Emitting Diode, active-matrix organic light-emitting diode) display devices are gradually developed, and correspondingly, large-size AMOLED display devices are also A larger size panel and a larger number of pixels are required. However, as the length of the p...
