Abstract:
The present disclosure relates to a display device. The display device includes a display panel, data lines, a constant voltage line, a feedback line, and a display driver. The display panel includes pixels. The data lines transfer data voltages to the pixels. The constant voltage line transfers a constant voltage to the pixels. The feedback line is coupled to the constant voltage line. The display driver is configured to sense a change amount of the constant voltage through the feedback line, generate compensated image data by compensating image data according to the sensed change amount of the constant voltage, and provide the data voltages corresponding to the compensated image data to the pixels.
