Abstract
A shift register includes a control circuit, a switching circuit, a driving circuit, and a pull-down circuit. The control circuit is configured to output a control signal having a high level during a pull-up period and a voltage-regulating period respectively. The switching circuit is configured to provide a control voltage according to the control signal and a front stage signal outputted by a front x-stage shift register during the pull-up period. The driving circuit is configured to generate a driving signal according to the control voltage provided by the switching circuit, and output a home stage scan signal based on the driving signal. The pull-down circuit is configured to pull down a voltage level of the driving signal according to a scan signal outputted by a rear y-stage shift register during a pull-down period. The switching circuit is configured to regulate the driving signal and the home stage scan signal.
