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.

Abstract: A display panel (100) and a display device (1) are disclosed. The display panel (100) includes: a first group of scan lines (110), a second group of scan lines (120), pixel units (150), data lines (140), and a switching module (160). In the first display mode, the switching module (160) controls the first group of scan lines (110) to be turned on to charge the corresponding pixel units (150). In the second display mode, the switching module (160) controls the second group of scan lines (120) to be turned on to charge the corresponding pixel units (150).
