Abstract
A display device, a gate drive circuit, a shift register and a control method are disclosed. A first shift register unit of the shift register is configured to write a first control signal to a first node under control of a first input signal, write a first clock signal to a first signal output terminal; a second shift register unit of the shift register is configured to write a second control signal to the first node under control of a second input signal, write a second clock signal to a second signal output terminal; during the first frame, the first clock signal and the first input signal are pulse signals, the second clock signal and the second input signal are DC signals; during the second frame, the first clock signal and the first input signal are DC signals, the second clock signal and the second input signal are pulse signals.
