Abstract
A shift register circuit, a scan driving circuit, a display device and method for driving the scan driving circuit are provided. The shift register circuit includes: an input circuit for providing an active level for the first node upon receiving the active level of scan trigger signal; a trigger circuit for outputting the active level of scan trigger signal at the second node when first node is at the active level and a first clock signal is at first level; a locking circuit for locking the level of first node as inactive level when a first control signal is at the active level; and an output circuit for outputting a gate turn-on voltage during a period in which the second node is at an active level of the scan trigger signal, and outputting a voltage same as voltage of a second control signal during other periods other than the period.
