Patent ID: 8138997

Claim:
An organic light emitting display, comprising: a scan driver configured to sequentially supply a scan signal to scan lines and sequentially supply a light emitting control signal to light emitting control lines; a data driver configured to supply a data signal to data lines; and pixels arranged coupled to the scan lines, the data lines and the light emitting control lines, wherein: each of the pixels includes: an organic light emitting diode, a second transistor controlling an amount of electric current supplied to the organic light emitting diode, a storage capacitor coupled between an i−1 th light emitting control line and a gate electrode of the second transistor, a first transistor coupled between an i th scan line, a data line and a first electrode of the second transistor, the first transistor being turned on when a scan signal is supplied to the i th scan line, a third transistor coupled between the gate electrode and a second electrode of the second transistor, the third transistor being turned on when the scan signal is supplied to the i th scan line, and a boosting capacitor coupled between the gate electrode of the second transistor and the i th scan line, the light emitting control signal has a base voltage and a positive pulse voltage, the scan signal has a base voltage and a negative pulse voltage, and the positive pulse voltage of the light emitting control signal is greater than the base voltage of the scan signal.
