Patent ID: 8717272

Claim:
An organic light emitting display device comprising: a scan driver for sequentially supplying a plurality of first scan signals to a plurality of first scan lines, sequentially supplying a plurality of second scan signals to a plurality of second scan lines, and sequentially supplying a plurality of light emitting control signals to a plurality of light emitting control lines, the scan driver being adapted to supply one of the first scan signals to a first scan line of the plurality of first scan lines during a first period and a second period of a horizontal period, the second period immediately following the first period, to supply one of the second scan signals to a second scan line of the plurality of second scan lines during the first period, the one of the first scan signals and the one of the second scan signals being supplied starting at substantially the same time, and to supply one of the light emitting control signals to a corresponding one of the light emitting control lines during a period at least spanning the first period and the second period; a data driver for supplying in a sequential order a plurality of data signals to at least one of a plurality of output lines, the data driver being adapted to supply the data signals to the at least one of the output lines during the first period; a demultiplexer electrically coupled to the at least one of the output lines, the demultiplexer adapted to receive the data signals and supply the data signals to a plurality of data lines; and a plurality of pixels connected to the data lines, each of the pixels including a driving transistor and being adapted to receive a respective one of the data signals during the first period, to compensate a threshold voltage of the respective driving transistor during the second period, and to generate light having a brightness corresponding to the respective one of the data signals at a time after an end of the second period.
