Abstract
Provided is an organic light emitting diode display including a display panel having data lines, gate lines, and pixels disposed in a matrix form in a crossing region of the data lines and the gate lines, a gamma reference voltage adjustment unit that calculates a weighted average picture level of digital video data, adjusts gamma reference voltages so that peak luminance of the display panel is reduced as the weighted average picture level is increased, and outputs the adjusted gamma reference voltages, a data driving circuit converting the digital video data into analog data voltages by using the gamma reference voltages, and supplying the data voltages to the data lines, and a gate driving circuit sequentially outputting gate pulses to the gate lines.
