Patent ID: 8232933

Claim:
An organic light emitting display, comprising: a scan line; a data line; and a pixel coupled to the scan line and the data line; wherein the pixel comprises: a first switching transistor including a control electrode coupled to the scan line, and a first electrode coupled to the data line; a driving transistor connected between a first power supply line and a second power supply line, the driving transistor including a control electrode coupled to the first switching transistor; a first storage capacitor connected to the first switching transistor, the first power supply line and the driving transistor; a second switching transistor connected between the first power supply line and the driving transistor, the second switching transistor comprising a control electrode coupled to an emission control line; a second storage capacitor connected to the first switching transistor and connected to the first storage capacitor and connected to the second switching transistor and connected to the driving transistor; and an organic light emitting diode coupled between the driving transistor and the second power supply line, wherein the second storage capacitor is not a parasitic capacitor of the driving transistor.
