Abstract:
The present disclosure provides a scanning driving circuit and a display device. The scanning driving circuit includes a plurality of stages of scanning driving units in cascade connection. The plurality of stages of scanning driving units include a first stage scanning driving unit, a plurality of intermediate stage scanning driving units and a last stage scanning driving unit each including a forward and reverse scanning circuit configured to control the scanning driving circuit to forward scanning or reverse scanning, an input circuit configured to charge a pull-up control signal point, a latch circuit configured to latch a signal of the pull-up control signal point, an output circuit configured to generate a scanning driving signal, and a reset circuit configured to reset the pull-up control signal point, which reduces the number of signal lines, simplifies the signal line design, saves space and facilitates the narrow frame design.
