Abstract:
An AMOLED pixel circuit and driving method are disclosed. The AMOLED pixel circuit comprises a first transistor (T1), a second transistor (T2), a third transistor (T3), a fourth transistor (T4), a fifth transistor (T5), a sixth transistor (T6), a seventh transistor (T7), an eighth transistor (T8), a first capacitor (C1), a second capacitor (C2), a current source and a light-emitting device (OLED). The AMOLED pixel circuit can perform a rapid charging in a low gray scale state; different currents may be provided according to information on a high or low gray scale, and thus the AMOLED pixel circuit may be applied widely; an output current during a light-emitting period is a normal operational current of the light-emitting device; therefore not only a charging process is expedited, but also a normal operation of the light-emitting device is ensured.
