Driving circuit and driving method for AMOLED pixel circuit

A control unit which is connected to an output terminal of a gate driver and receives driving pulses (Gn) from the gate driver, comprising a first module (T5, T6) and a second module (T7, T8), and input terminals of the first module (T5, T6) and the second module (T7, T8) are connected with a first control voltage (VGL1) and the pulses (Gn), respectively, wherein

• the first module (T5, T6) converts the received pulses (Gn) into a first group of pulses (Sin) and outputs them under control of a first group of control signal lines (SEL1, SEL2);
• and
• the second module (T7, T8) converts the received pulses (Gn) into a second group of pulses (S2n) and outputs them under control of a second group of control signal lines (SEL3, SEL4),
• the first module (T5, T6) comprises a first control transistor (T5) and a second control transistor (T6), the second module (T7, T8) comprises a third control transistor (T7) and a fourth control transistor (T8);
• the first group of control signal line (SEL1, SEL2) comprises a first control signal line (SEL1) and a second control signal line (SEL2);
• and the second group of control signal lines (SEL3, SEL4) comprises a third control signal line (SEL3) and a fourth control signal line (SEL4).
