Abstract
An output control unit of a shift register, a shift register and a driving method thereof, and a gate driving device. The output control unit includes N pull-up units, N pull-down units, and N signal output terminals. The nth pull-up unit is connected with a pull-up node, a high voltage source, an nth clock signal input terminal and an nth pull-down unit, the nth pull-down unit is connected to a pull-down node and a low voltage power source, and a connection point of the nth pull-up unit and the nth pull-down unit is further connected to the nth signal output terminal. The output control unit is configured to: provide clock signals from N clock signal input terminals to the N signal output terminals respectively under the control of a voltage of the pull-up node, and pull down levels of output signals of the N signal output terminals.
