摘要： Embodiments of the present disclosure provide a shift register unit and a driving method thereof, a gate driving circuit and a display device. The shift register unit comprises a latch module and a latch output module. Switching on and off of the transmission gates is controlled by using an intermediate signal generated based on a clock signal and an inputted signal, instead of by using the clock signal, such that the shift register unit will not be influenced by frequent flips of the clock signal in a non-operational state, thus avoiding a great deal of useless power consumption.

摘要： An OLED AC driving circuit, a driving method and a display device are disclosed in the present disclosure. The OLED AC driving circuit includes a light-emitting control unit, a charging unit, a driving unit, a first storage unit, a second storage unit, a first light-emitting unit, a second light-emitting unit, a first voltage control unit and a second voltage control unit. The present disclosure employs the first light-emitting unit and the second light-emitting unit which are connected reversely with each other to make the first light-emitting unit and the second light-emitting unit emit light alternately during two adjacent frames. In one frame, only one light-emitting unit emits light for display while the other one is reversely biased. When the next frame comes, the two units exchange their operating states. The AC driving of the light-emitting units is realized, thus improving the energy utilization efficiency. The cause of the aging of the light-emitting unit is removed completely, and the lifespan of the light-emitting unit is extended largely. The influence of the internal resistance of the lines on the light-emitting current is eliminated, and the display quality of pictures is improved.
