Abstract: A bi-directional scanning unit, a driving method and a gate driving circuit are provided. The bi-directional scanning unit includes a first stage subunit and a second stage subunit. The bi-directional scanning unit outputs a scanning signal stage by stage in a direction from the first stage subunit to the second stage subunit and outputs a scanning signal stage by stage in a direction from the second stage subunit to the first stage subunit. During the scanning, the first stage subunit and the second stage subunit cooperate with each other, so that one of the stage subunits does not output a scanning signal while the other one outputs a scanning signal. With the technical solutions according to the embodiments, the bi-directional scanning unit can output two-stage scanning signals stage by stage, have a simplified structure, and satisfy diverse demands on the gate driving circuit.

Abstract translation: 提供双向扫描单元，驱动方法和栅极驱动电路。 双向扫描单元包括第一级子单元和第二级子单元。 双向扫描单元在从第一级子单元到第二级子单元的方向逐级地输出扫描信号，并且在从第二级子单元到第一级子单元的方向逐级输出扫描信号。 在扫描期间，第一级子单元和第二级子单元彼此协作，使得一个级子单元不输出扫描信号，而另一个输出扫描信号。 利用根据实施例的技术方案，双向扫描单元可以逐级输出两级扫描信号，具有简化的结构，并满足对栅极驱动电路的不同要求。
