Shift register circuit and display panel using same

A shift register circuit, comprising a plurality of stages of shift registers, wherein each shift register comprises:

• a first switch, wherein a control end of the first switch is electrically coupled to a first node, a first end of the first switch is electrically coupled to a frequency signal, and a second end of the first switch is electrically coupled to an output pulse signal;
• a second switch, wherein a control end of the second switch is electrically coupled to a control signal, a first end of the second switch is electrically coupled to the control signal, and a second end of the second switch is electrically coupled to the first node;
• a third switch, wherein a control end of the third switch is electrically coupled to the first node, a first end of the third switch is electrically coupled to the frequency signal, and a second end of the third switch is electrically coupled to a control signal;
• and
• a fourth switch, wherein a control end of the fourth switch is electrically coupled to the first node, a first end of the fourth switch is electrically coupled to the frequency signal, and a second end of the fourth switch is electrically coupled for generating a feedback signal.
