Patent ID: 8242984

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