Abstract
The present disclosure provides a gate driving circuit, a shift register, and a driving control method thereof. The shift register includes: a gate signal generation circuit configured to generate a first gate signal for gating transistors, wherein the gating transistors comprise a first gating transistor and a second gating transistor coupled in series; a gate signal output control circuit configured to receive a first level signal, and output a first gate signal from the gate signal generation circuit to the first gating transistor and the second gating transistor under control of the first level signal; and a control circuit configured to receive a second level signal, a first control signal, and a second control signal, and output the first control signal to the first gating transistor and output the second control signal to the second gating transistor under control of the second level signal.
