Abstract

There are provided a shift register, a gate driving circuit and a relevant display device, comprising a first node controlling module (1), a second node controlling module (2), a third node controlling module (3), a first outputting module (4) and a second outputting module (5). The first node controlling module (1) adjust a potential of a first node (A), the second node controlling module (2) adjust a potential of a second node (B), the third node controlling module (3) adjust a potential of a third node (C), the first outputting module (4) adjust a potential of a driving signal output terminal (Output), and the second outputting module (5) adjusts the potential of the driving signal output terminal (Output). Through mutual coordination of the five modules, the shift register could control a time length of a scanning signal outputted by the driving signal output terminal (Output) by only changing a time length of an input signal (Input), without changing clock signals (CK,CB) and changing the circuit and process, so that difficulty of the gate driving circuit and complexity of process could be reduced, thereby the cost is reduced.
