Abstract
An organic light emitting diode display device is disclosed which adjusts brightnesses and color temperatures of RGBW data signals and matches the brightnesses of organic light emitting diodes and the color temperature of a white organic light emitting diode with the target brightness value and the target color temperature of a white pixel. As such, an overcompensation and the reduction of a lifespan can be prevented. Also, relatively high brightness and color temperature can be maintained.
