Abstract
Discussed is an organic light emitting display device including a display panel; a human body detection unit to detect a human body existing in front of the display panel; a human body determination unit to determine whether the human body exists and a location of the human body with respect to the display panel based on detection information from the human body detection unit; a brightness control unit to determine whether to control a brightness of the display panel based on a result of the determination by the human determination unit; and a timing controller to control image data provided to the display panel based on the determination from the brightness control unit. Accordingly, a viewer can view a sufficiently bright image, and energy can be saved and threshold voltage (Vth) difference can be compensated for.
