The first and second subpixel electrodes are electrically connected through first and second switching elements to a data line supplied with a data voltage. The first subpixel electrode is electrically connected through a third switching element to one of the first and second reference voltage lines. A polarity of the first reference voltage is different from a polarity of the second reference voltage with respect to the common voltage supplied to the common electrode. Liquid crystal molecules are disposed between the first subpixel electrode and the common electrode and between the second subpixel electrode and the common electrode.

Abstract: An organic light emitting display device includes a data driver, a pixel unit, a timing controller, and a power generator. The data driver generates data signals to be supplied to data lines based on gamma voltages. The pixel unit controls the amount of current flowing from a first power supply to a second power supply in each of a plurality of pixels based on the data signals and a reference power voltage. The timing controller limits the maximum brightness of the pixel unit corresponding to a plurality of dimming levels. The first power generator changes the voltage of the first power supply corresponding to the dimming levels.
