Display panel and bi-directional shift register circuit

A bi-directional shift register circuit for generating a plurality of gate driving signals and comprising a plurality of shift registers, wherein at least one shift register comprises:

• an input circuit, coupled to a first input terminal and a second input terminal for respectively receiving a first input signal and a second input signal;
• an output circuit, coupled to a first clock input terminal for receiving a first clock signal and outputting a pulse signal at an output terminal according to the first clock signal;
• a control circuit, coupled to the output circuit via a first control node, a second control node and a third control node and controls voltages at the first control node, the second control node and the third control node according to the first input signal or the second input signal, and further controls operations of the output circuit;
• a second clock input terminal, receiving a second clock signal;
• and
• a third clock input signal, receiving a third clock signal,
• wherein when the shift register operates in a forward scan, a falling edge of the first clock signal closes to a rising edge of the second clock signal, and when the shift register operates in a reverse scan, the falling of the first clock signal closes to a rising edge of the third clock signal.
