Abstract
The present application provides a gate drive circuit, a drive device and a display device. The gate drive circuit includes m switch groups, n first shift registers and m second shift registers. Each switch group includes n first switch units. The n first shift registers cyclically output a first row-scan signal, while each second shift register controls the n first switch units connected to each first controlled node corresponding to the second shift register to be turned on, so that the first row-scan signal is fed back to each gate-line in turn, to realize a line-by-line scan driver. The gate drive circuit only needs n+m shift registers to complete the gate drive, compared with the existing gate drive circuit requiring n×m shift registers, the number of shift registers is reduced, the cost is reduced and the manufacturing process is simplified.
