Patent ID: 8610700

Claim:
An organic light emitting display, comprising: a scan driver for sequentially supplying a scan signal to a plurality of scan lines and sequentially supplying an emission control signal to a plurality of emission control lines; a data driver for supplying a data signal to a plurality of data lines in synchronization with the scan signal; a power source unit for supplying a first power source to a plurality of power source lines; and a plurality of pixels at respective crossing regions of the scan lines, the emission control lines, and the data lines, wherein each of the pixels at an ith (i is a natural number) horizontal line of a plurality of horizontal lines comprises: an organic light emitting diode (OLED); a first transistor coupled between a corresponding power source line of the power source lines and the OLED to control an amount of current supplied to the OLED; a second transistor having a gate electrode coupled to an ith scan line of the scan lines to be turned on when the scan signal is supplied to the ith scan line to supply the data signal to the gate electrode of the first transistor; a third transistor coupled between the OLED and the first transistor and having a gate electrode coupled to an ith emission control line of the emission control lines; and a storage capacitor having a first electrode directly coupled to the gate electrode of the first transistor and a second electrode directly coupled to an anode electrode of the OLED, wherein the second electrode of the storage capacitor is further coupled to the first transistor through the third transistor.
