Patent ID: 8810484

Claim:
An organic light emitting display comprising: a display unit comprising a plurality of pixels at crossing regions of a plurality of scan lines, a plurality of data lines, and a plurality of emission control lines, the display unit being divided into at least k blocks, wherein k is a natural number greater than 1, each of the blocks comprising a plurality of corresponding scan lines of the scan lines; a plurality of k scan drivers each coupled to a corresponding one of the blocks for supplying a plurality of scan signals to the corresponding scan lines; a plurality of emission drivers included in the blocks for supplying a plurality of emission control signals to the emission control lines, each of the blocks comprising a plurality of corresponding emission control lines of the emission control lines; a data driver for supplying a plurality of data signals to the data lines; and a timing controller for controlling the scan drivers, the emission drivers, and the data driver, for supplying a plurality of start signals, for supplying a plurality of scan control signals, and for supplying a plurality of emission block control signals to control light emission of the pixels, wherein the pixels in a same one of the blocks are configured to receive a same one of the emission block control signals, wherein the pixels are configured to be set in a non-emission state when the pixels receive a corresponding one of the emission block control signals, and wherein a first scan driver of the scan drivers is controlled by a first scan control signal of the scan control signals, and a second scan driver of the scan drivers is controlled by a second scan control signal of the scan control signals, the first scan control signal being different from the second scan control signal, wherein each of the scan control signals overlaps a corresponding start signal of the plurality of start signals.
