Abstract
A shift register circuit includes a driving unit outputting a first scan signal according to a first clock signal; a pull up unit outputting a driving voltage according to one of a second scan signal and a third scan signal; a pull down unit pulling down voltage of an output end according to a second clock signal; a pull down control unit controlling the voltage of the output end and a driving node according to the first clock signal; a reset unit pulling down the voltage level of the driving node according to a touch-enable signal; and an electric storage unit adjusting the voltage of the driving node according to a touch-stop signal. When the touch-enable signal is enabled, the clock signals and the touch-stop signal are disabled, and when the touch-stop signal is enabled, the clock signals and the touch-enable signal are disabled.
