Abstract
A shift register unit, a shift register and the scanning method thereof, and a display device are disclosed. Bidirectional scanning can be achieved while the number of the switches used in the shift register could be reduced, and the spaces are saved. Furthermore, the problem of large coupled noise voltage is solved, and the performance of the shift register is improved. The circuit comprises: a second switch connected with a first switch; a fourth switch connected with a third switch; a fifth switch connected with a sixth switch; a first input and a eighth switch connected with a seventh switch; a output end and a ninth switch connected with the eighth switch; an eleventh, a twelfth, and a thirteenth switch connected with a tenth switch; a fourteenth switch connected with the thirteenth switch; a fifteenth switch connected with the fourteenth switch; a capacitor positioned between a first node and a second nodes.
