Abstract
A shift register circuit includes a set circuit, a first reset circuit, a first control circuit, and an output circuit. The output circuit is configured to change an active potential at the first node further away from an inactive potential in response to a first clock signal transferred to a signal output terminal being active, and the first control circuit is further configured to, responsive to the first clock signal transferred to the signal output terminal being active, restrict a change in the active potential at the first node based on a second reference voltage from a second reference voltage, the second reference voltage having a magnitude between an active input pulse and the inactive potential.
