Abstract
A display device, a luminance compensation circuit thereof and a luminance compensation method are provided. In the luminance compensation method, the display device includes a display region and a peripheral region located on a periphery of the display region, where the display region includes a first pixel region and a second pixel region, a pixel density of the second pixel region is lower than a pixel density of the first pixel region; the luminance compensation method includes: adjusting a power supply signal of the first pixel region and/or a power supply signal of the second pixel region, respectively, according to the first light-emitting luminance information of the first pixel region and the second light-emitting luminance information of the second pixel region.
