Patent ID: 7239296

Claim:
A circuit for driving pixels of an organic light-emitting display, comprising: a thin-film transistor having a source terminal connected to a voltage source; a storage capacitor having a first terminal connected to a gate terminal of the thin-film transistor; and an organic light-emitting diode having a cathode grounded; wherein when in a clamping phase, the gate terminal of the thin-film transistor is connected to a drain terminal of the thin-film transistor and a second terminal of the storage capacitor is grounded; when in a light-emitting phase, the second terminal of the storage capacitor is connected to a data line and an anode of the organic light-emitting diode is connected to the drain terminal of the thin-film transistor; when in a reverse phase, the gate terminal of the thin-film transistor is connected to the drain terminal of the thin-film transistor, the second terminal of the storage capacitor is connected to the data line, and the anode of the organic light-emitting diode is connected to the drain terminal of the thin-film transistor.
