DRIVING CIRCUIT OF AMOLED AND METHOD FOR DRIVING THE AMOLED

摘要

A driving circuit of an active matrix/organic light emitting diode (AMOLED) includes a first semiconductor controllable switch, a second semiconductor controllable switch, an energy-storage. capacitor, an organic light emitting diode, and a sequential control unit that divides a driving time of one frame of the organic light emitting diode into driving times of N subframes. An output end of the second semiconductor controllable switch is coupled to an anode of the organic light emitting diode, a source electrode of the first semiconductor controllable switch receives a data driving signal of the AMOLED, a gate electrode of the first semiconductor controllable switch receives a scan driving signal of the AMOLED, a drain electrode of the AMOLED is connected with a gate electrode of the second semiconductor controllable switch, and the energy-storage capacitor is connected in series between a source electrode and the gate electrode of the second semiconductor controllable switch. The data driving signal is divided into an active signal that drives display of the organic light emitting diode and a blanking signal that turns off display of the organic light emitting diode in the driving time of each of the subframes.
