1. An organic light emitting diode (OLED) display including a plurality of data lines, a plurality of scan lines, and a plurality of pixels connected to a corresponding data line, a corresponding scan line, a first power source voltage application line, and a second power source voltage application line, wherein the plurality of pixels respectively include first to third subpixels emitting light according to first image data for a first color, second image data for a second color, and third image data for a third color, comprising:
a power supplier respectively supplying a first power source voltage and a second power source voltage to the first and second power source voltage application lines; and a power source controller calculating a reference power source voltage corresponding to a maximum average grayscale using a distribution for each grayscale of the first to third image data, modeling each voltage drop of the first and second power source voltages for the first to third subpixels, and reflecting the voltage drop to the reference power source voltage to change the second power source voltage. |
