Abstract

A shift register includes a first voltage stabilizing unit, a second voltage stabilizing unit, a main pull-down unit and a main pull-up unit. The first voltage stabilizing unit is used to pull a first driving control signal to a low voltage terminal when a first stabilizing control signal is high. The second voltage stabilizing unit is used to pull the first driving control signal to the low voltage terminal when a second stabilizing control signal is high. The main pull-down unit includes a first sub-pull-down unit controlled by a second gate-terminal signal for pulling down the first driving control signal to the low voltage terminal during a first display mode, and a second sub-pull-down unit controlled by a third gate-terminal signal for pulling down the first driving control signal to the low voltage terminal during a second display mode. The main pull-up unit is used for pulling up a first gate-terminal signal.
