Abstract
The present disclosure provides a luminance adjustment method and device of a display panel. In the method, firstly, a difference between the luminance parameters of different regions of the target panel are obtained, and temperatures of different regions of the target panel are obtained according to the difference of the luminance parameters of the different regions of the target panel. Then, luminance compensation parameters of the corresponding regions are obtained according to a correlation of the luminance to the temperature and a difference of the operating temperatures of the different regions, and finally, the luminance of a corresponding region is compensated according to the luminance compensation parameters.
