1. A display device comprising:
a pixel;
a sensor to sense characteristic values of a circuit element of the pixel in a sensing period of a frame period; and
a controller to adjust an initialization voltage supplied to the pixel based on the characteristic values and a margin value of the initialization voltage, wherein after a first time is elapsed, the initialization voltage supplied to the pixel in the sensing period is set to a first voltage value, after a second time different from the first time is elapsed, the initialization voltage supplied to the pixel is set to a second voltage value greater than the first voltage value.
