Abstract
A display device includes a pixel array, a power line, a ground line, at least one power detection line, at least one ground detection line, and a power supply circuit. The 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 at least one detected supply voltage via the at least one power detection line and at least one detected ground voltage via the at least one ground detection line, and adjust the supply voltage and/or the ground voltage according to the at least one detected supply voltage and the at least one detected ground voltage.
