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.
