1. A display device comprising:
a display panel including a pixel;
a data driver which provides a data voltage to the pixel;
a power voltage generator which provides a first initialization voltage and a first power voltage to the pixel; and
a driving controller which controls the data driver and the power voltage generator,
wherein the driving controller determines a difference between the first initialization voltage and the first power voltage based on an input luminance.
 
17. A method of driving a display device, the method comprising:
determining an input luminance;
determining a difference between a first initialization voltage and a first power voltage based on the input luminance;
determining the first power voltage; and
determining the first initialization voltage based on the difference and the first power voltage.
