ABSTRACT:
An organic light emitting display device includes a display area including pixels coupled to scan, light emission control, and data lines; a scan driver electrically coupled to the display area through the scan and light emission control lines; a data driver electrically coupled to the display area through the data lines; an optical sensor for generating a sensor signal corresponding to an ambient light brightness; a first luminance control unit for outputting a first luminance control signal (Vc1) for controlling a gamma-corrected gray level voltage of a data signal in accordance with the sensor signal; a second luminance control unit for outputting a second luminance control signal (Vc2) for controlling a width of a light emission control signal in accordance with data of one frame; and a comparator/selector for comparing the first and second luminance control signals to output one of them into the data driver or the scan driver.
