Patent ID: 8648775

Claim:
An organic light emitting display including an organic light emitting display panel, the organic light emitting display comprising: an emission control driver of the organic light emitting display panel; a sensor unit for outputting an electrical output signal by sensing an external light; a signal processing unit for determining an indoor mode or an outdoor mode in accordance with the output signal outputted from the sensor unit; an onscreen display control unit electrically connected to the signal processing unit and for controlling the emission control driver of the organic light emitting display panel; a first display area comprising a plurality of first pixels electrically connected to the emission control driver through a plurality of first emission control lines; and a second display area comprising a plurality of second pixels electrically connected to the emission control driver through at least one second emission control line, wherein at least two of the second pixels are immediately adjacent each other and are electrically connected to one of the at least one second emission control line and the first pixels coupled to a portion of a same scan line as the at least two of the second pixels are electrically connected to one of the first emission control lines, such that light emission of the at least one of the second pixels is controlled according to the external light independently of the first pixels coupled to the same scan line, and wherein the second display area is smaller than the first display area.
