Abstract
A display device includes: a plurality of pixels; a degradation compensator for using a temperature weight value for a reference temperature, a luminance weight value for a reference luminance, and a material weight value for a reference material, for calculating a reference using time when a degradation rate of the pixels is changed to a reference degradation rate of a reference degradation curve, and for generating a control variable according to the reference using time; and a power supply for controlling a voltage difference between a first power source voltage for supplying a driving current to the pixels and a second power source voltage according to the control variable.
