Abstract
A shift register circuit has a plurality of shift registers. Each of the shift registers has at least four input terminals, a signal input terminal, an output terminal, a pull-up circuit, a driving circuit, a stability driving circuit, and a pull-down circuit. The signal input terminal receives an input signal, and the pull-up circuit is configured to pull up a voltage level of a node of the shift register. The driving circuit outputs a gate driving signal according to the voltage level of the node. The pull-down circuit is configured to pull down the voltage level of the node. The stability driving circuit can pull down the voltage of the output terminal according to the voltages of the four input terminals, and, thus, can reduce the response time of the shift register circuit and increase the operation region of the shift register circuit.
