Abstract
A display device, a gate drive circuit, a shift register and its control method are described. The shift register includes: an input circuit, a first output circuit, a second output circuit, a control circuit and an output drive circuit, wherein the output drive circuit is connected to a second signal input terminal, a pull-up node, a control terminal of the second output circuit and a low voltage signal terminal, and is configured to write a voltage of the second signal input terminal into the control terminal of the second output circuit and superimpose a voltage of the pull-up node onto the control terminal of the second output circuit under the control of a second input signal provided at the second signal input terminal, such that the second output circuit is fully turned on to ensure that it has good output capability when working at a low temperature.
