ABSTRACT:
An organic light emitting diode (OLED) display device, including a pixel unit including a plurality of pixels connected to scan lines and data lines, a scan driver adapted to generate and supply scan signals to the scan lines, a data driver adapted to generate and supply data signals to the data lines, an optical sensor adapted to generate an optical sensor signal to correspond to an intensity of light, and a data conversion unit adapted to compare a predetermined reference value with the optical sensor signal so as to generate a selection signal for selecting one of at least three modes. The data conversion unit may be adapted to store an input image data or a changing data changed from the input image data to correspond with the selection signal. The data driver may generate the data signals to correspond to the input image data or the changing data stored in the data conversion unit.
