Abstract
The present disclosure provides a gate driving module, including a gate driving circuit and a control circuit. The gate driving circuit includes a first shift register sub-circuitry and a second shift register sub-circuitry connected to each other in a cascaded manner. A first shift register unit is connected to a corresponding gate line at a first display sub-region. A second shift register unit is connected to a clock signal line and a corresponding gate line at a second display sub-region, and configured to generate a gate driving signal in accordance with a voltage signal on the clock signal line and output the gate driving signal to the gate line. The control circuit is configured to, when a display panel is in a non-planar state and the second shift register unit is performing a gate driving scanning operation, apply a first voltage signal to the clock signal line, so as to enable the second shift register unit to output a signal for turning off a transistor corresponding to the gate line.
