Abstract
An organic light emitting diode display including a display panel having a plurality of data lines, a plurality of gate lines, and a plurality of pixels, a data drive circuit that converts input digital video data into data voltage with reference to gamma reference voltages and supplies the data voltage to the data lines, a gamma reference voltage generation circuit that generates the gamma reference voltages by dividing a high potential gamma power; and a gamma power adjusting circuit that adjusts display luminance by extracting a number of white pixels from the input digital video data and adjusting the output level of the high potential gamma power depending on the number of white pixels.
