Abstract: A display device can include a display panel having a plurality of subpixels; a gate driving circuit configured to supply a plurality of scan signals to the display panel through a plurality of gate lines, and output a feedback voltage; a data driving circuit configured to supply a plurality of data voltages to the display panel through a plurality of data lines; a power management circuit configured to supply a plurality of driving voltages to the gate driving circuit and the data driving circuit, and supply a compensating high-potential gate voltage to the gate driving circuit based on the feedback voltage transferred from the gate driving circuit. The display device can further include a timing controller configured to control the gate driving circuit, the data driving circuit, and the power management circuit.
