Claim 0:
1. A display device comprising:
a display panel which displays an image based on a data voltage;
a driving controller which generates a data signal based on input image data;
a data driver which converts the data signal into the data voltage and outputs the data voltage to the display panel; and
a power supply voltage generator which senses a power supply current applied to the display panel in a frame and adjusts a power supply voltage applied to the display panel based on a current level of the power supply current,
wherein the driving controller performs a net power control operation for an (N+1)th frame, which adjusts a gray scale of (N+1)th frame data based on a load of Nth frame data, where N is a natural number greater than or equal to 2.
