Abstract

The present disclosure relates to a display device, a display substrate, a method and a device for display compensation. The method includes: before displaying an image, performing initial compensation on each of the pixel circuits to obtain an average reference voltage of the plurality of pixel circuits; controlling the display substrate to display an image and performing external compensation on each of the pixel circuits during a display duration of one frame of the image, obtaining a charging voltage on the sensing line of each of the pixel circuits during the external compensation, obtaining a first reference voltage of each of the pixel circuits according to the charging voltage on the sensing line and the average reference voltage, and performing internal compensation on each of the pixel circuits according to the first reference voltage.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display compensation method, a display compensation device, a display substrate and a display device. Background technique [0002] With the advancement of time, AMOLED (Active Matrix Organic Light Emitting Diode, active matrix organic light emitting diode) products are more and more widely used, with its advantages of high contrast, high color gamut, light and thin, and can be made into flexible screens. , is increasingly recognized by people. [0003] With the widespread use of AMOLED products, some problems in the display process need to be properly resolved. For example, due to reasons such as technology, materials, and design, the threshold voltage of the drive transistor in the AMOLED product drifts, which in turn leads to uneven display and poor display effect. Contents of the invention [0004] The present invention aims to solve one of the technical proble...
