1. An electronic device comprising:
a processor configured to provide input image data; and
a display device configured to receive the input image data from the processor, and to display an image based on the input image data, the display device comprising:
a display panel including pixels; and
a panel driver configured to sequentially apply data voltages to the pixels on a row basis in an active period of a frame period, and to perform a sensing operation on at least one pixel of the pixels in a blank period of the frame period,
wherein, within the blank period, the panel driver applies a pre-charge data voltage to the at least one pixel after the sensing operation, and applies a previous data voltage to the at least one pixel after a predetermined time from a time point at which the pre-charge data voltage is applied,
wherein the pre-charge data voltage is higher than a maximum gray data voltage.
