Abstract
The present disclosure provides a display panel, a method for compensating a common voltage thereof, and a display device, belongs to the field of display technology and can solve the problem that the existing display panel cannot effectively compensate the common voltage in the middle region thereof. The display panel includes a plurality of compensation regions, each of the compensation regions is provided with a plurality of common electrodes. The display panel includes a compensation circuit corresponding to each compensation region. The compensation circuit may compensate an actual common voltage of the common electrode in a corresponding compensation region, according to an average value of a difference between an actual common voltage and a preset common voltage of each common electrode in the corresponding compensation region.
