Patent ID: 8289237

Claim:
An organic light emitting display, comprising: a scan driver configured to sequentially supply a scan signal to a plurality of scan lines during a plurality of subframe periods during one frame and to supply a reset signal to a plurality of reset lines; a data driver configured to apply data signals to a plurality of data lines such that the data signal is synchronized with the scan signal; a plurality of pixels configured to emit red light each connected to the scan lines and the reset lines; a plurality of pixels configured to emit green light each connected to the scan lines and the reset lines; and a plurality of pixels configured to emit blue light each connected to the scan lines and the reset lines; wherein the scan driver is configured to control the duration of light emission periods, and the duration of the emission period for each of the pixels is based on the color of the light emitted by the pixel, and wherein each of the pixels comprises: an organic light emitting diode, a first transistor having a gate electrode connected to a scan line and a first electrode connected to a data line, the first transistor configured to be turned on when a scan signal is supplied to the scan line, a second transistor having a gate electrode connected to a second electrode of the first transistor, a first electrode connected to a first power source and a second electrode connected to the organic light emitting diode, the second transistor configured to control an electric current flowing from the first power source to a second power source through the organic light emitting diode according to a data voltage from the data line, and a storage capacitor having one terminal connected to the second electrode of the first transistor and the gate electrode of the second transistor, and another terminal connected to a reset line, wherein if a reset signal is supplied to the reset line, the storage capacitor couples the reset signal to the second transistor, and in response to the coupled reset signal, the second transistor is turned off.
