Abstract

The present disclosure relates to a display panel, which comprises a first test circuit, the first test circuit comprising a first test trace extending along a first direction and a second test trace extending along a second direction, the first test trace being located between two adjacent sub-pixel columns, and the second test trace being located between two adjacent sub-pixel rows, the resistance values of the first test trace and the second test trace changing with temperature, and the resistance values being converted into a current temperature of a corresponding position of the display panel. Thus, the display panel can well reflect the temperature of the display panel itself. The present disclosure further provides a display module comprising the display panel, a display device comprising the display module, and a display effect adjusting method of the display device.
