1. A display device comprising:
a pixel array;
a power line;
a ground line;
a plurality of power detection lines;
a plurality of ground detection lines; and
a power supply circuit, configured to provide to the pixel array a supply voltage via the power line and a ground voltage via the ground line, receive from the pixel array a plurality of detected supply voltages via the plurality of power detection lines and a plurality of detected ground voltages via the plurality of ground detection lines, and adjust the supply voltage and/or the ground voltage according to the plurality of detected supply voltages and the plurality of detected ground voltages;
wherein the plurality of detected supply voltages are obtained from a plurality of different locations in the pixel array, and the plurality of detected ground voltages are obtained from the plurality of different locations in the pixel array.
