Abstract
The present disclosure provides a shift register, a display device, and a method for driving the display device. A pull-down module and a stop module are added in the shift register. When a full screen picture is displayed, the signal output port outputs a high-level signal to the gate line connected with the signal output port, such that the gate line scans the display panel of the display device normally. The pull-down module may maintain the pull-up node and the signal output port at a low-level during the non-working time of the shift register, so as to prevent the shift register from outputting noise. When a local picture is displayed, under the control of the stop signal input port Stop, the stop module outputs the low-level signal to the gate line connected with the signal output port, such that the gate line stops scanning the display panel.
