ABSTRACT:
An exemplary shift register (20) includes a plurality of shift register units (200) connected one by one. Each of the shift register units includes a clock signal input terminal (TS), a reverse clock signal input terminal (TSB), a high level signal input terminal (VH), a low level signal input terminal (VL), an output terminal (VOUT), a reverse output terminal (VOUTB), a first input terminal (VIN1), a second input terminal (VIN2), a common node (P), a first switch circuit (31) providing a high level signal to the common node, a second switch circuit (32) providing a low level signal to the common node, a third switch circuit (33) providing a clock signal to the output terminal, a fourth switch circuit (34) providing a low level signal to the output terminal, and an inverter (36) connected between the output terminal and the reverse output terminal.
