Abstract:
A pixel compensation circuit is disclosed. The circuit includes a light-emitting device, a reset module, a storage capacitor, a first, a second, a third, a fifth, and a sixth thin-film transistors. The reset module resets the gate of the first thin-film transistor and the anode of the light-emitting device according to a second scanning signal. A drain and a gate of the second thin-film transistor are connected to a data signal and the first scanning signal. The first scanning signal includes one or at least two continuous pulses in one frame time. When the AMOLED display panel needs a black insertion, a black insertion time is between a first pulse of the first scanning signal and a pulse of the second scanning signal, when the second scanning signal includes at least two continuous pulses within one frame time, at least two continuous pulses correspond to pulses of the data signal.
