Abstract
Embodiments of the present disclosure provide a light emission control shift register and method thereof, a gate driving circuit, and a display device. An input circuit outputs a signal of a signal input terminal to a first node. A first control circuit outputs a voltage of a first voltage terminal to a second node. A second control circuit transmits the voltage of the first voltage terminal to a third node. A third control circuit transmits the voltage of the first voltage terminal to a fourth node, and the third control circuit can further transmit the voltage of the second voltage terminal to the fourth node. A fourth control circuit transmits the voltage of the first voltage terminal to a signal output terminal, and the fourth control circuit can further transmit the voltage of the second voltage terminal to the signal output terminal.
