Abstract:
1. An organic light emitting display device for displaying an image, the organic light emitting display device having a plurality of scan lines, a plurality of light emission control lines and a plurality of data lines, and comprising: a display area including a plurality of pixels coupled to the scan lines, the light emission control lines and the data lines; a scan driver electrically coupled to the display area through the scan lines and the light emission control lines; a data driver electrically coupled to the display area through the data lines; an optical sensor for generating an optical sensor signal corresponding to a brightness of an ambient light; a first luminance control unit for providing to the data driver a first luminance control signal for controlling a gamma-corrected gray level voltage of a data signal applied to the data lines, in accordance with the optical sensor signal; and a second luminance control unit for providing to the scan driver a second luminance control signal for controlling a width of a light emission control signal applied to the light emission control lines, in accordance with the optical sensor signal and data of one frame of the image.
