1. A display device, comprising:
a plurality of pixels;
a power supply configured to generate an initialization voltage to be supplied to a sensing pixel, among the pixels;
a voltage measurer circuit configured to measure a first value of the initialization voltage supplied to the sensing pixel during an active period of a frame period and measure a second value of the initialization voltage supplied to the sensing pixel during a vertical blank period of the frame period; and
a timing controller configured to generate rewrite image data supplied to the sensing pixel during the vertical blank period, dependent on a difference between an initialization voltage that is supplied during the active period and an initialization voltage that is supplied during the vertical blank period.
