Abstract

The invention relates to a pixel compensation method, a pixel compensation system and a display device. The pixel compensation method comprises the following steps: in a current detection period, generating a source voltage signal according to gray scale data and compensation values of a plurality of sub-pixels so as to control the light emitting brightness of each sub-pixel; Generating a sensingvalue according to the current light-emitting brightness of each sub-pixel; And according to the gray scale data and the sensing value of each sub-pixel and the compensation value of the current period, determining the compensation value of each sub-pixel in the next detection period. According to the pixel compensation method provided by the invention, the comprehensive aging condition of each sub-pixel can be obtained according to the current light-emitting brightness of each sub-pixel, and the comprehensive aging condition of the whole pixel of each sub-pixel unit can be compensated once.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a pixel compensation method, a pixel compensation system, and a display device. Background technique [0002] Nowadays, human beings not only have strict requirements on the performance and quality of products, but also pay more attention to the price and practicality of products. In the field of display, especially in the field of OLED (Organic Light-Emitting Diode) display, it is widely recognized by the people because of its wide color gamut, wide viewing angle, thinner, lighter, lower energy consumption, high contrast ratio, and excellent flexibility. The reception has gradually become the development direction of the future display technology. [0003] However, in the field of large-scale display, the instability of each sub-pixel unit causes the picture quality to decrease, and improving the picture display quality has always been the direction of technical ...
