Abstract: The present disclosure discloses a shift register and a driving method thereof, a gate driving circuit, an array substrate, and a display device. With a signal control circuit, a branch control circuit, a cascade signal output circuit and at least two scanning signal output circuits, each shift register can output at least two different scanning signals to correspond to different gate lines in an array substrate. This can reduce the number of shift registers in a gate drive circuit and the space occupied by the gate drive circuit and can achieve an ultra-narrow bezel design, as compared with an existing shift register that can only output one scan signal. Furthermore, as signals of different output control node do not influence each other, the stability of waveforms of the output scanning signals may also be improved, and a difference in the waveforms of the scanning signals is avoided.
