Scanning driving circuit and display device

A display device, comprises a scanning driving circuit which comprises a plurality of stages of scanning driving units in cascade connection, the plurality of stages of scanning driving units comprise:

• a first stage scanning driving unit;
• a plurality of intermediate stage scanning driving units;
• a last stage scanning driving unit;
• wherein, the first stage scanning driving unit, each intermediate stage scanning driving unit, and the last stage last scanning driving unit each comprising:
• a forward and reverse scanning circuit, configured to control the scanning driving circuit to forward scanning or reverse scanning, wherein the forward and reverse scanning circuit of the first stage scanning driving unit receives a forward scanning control voltage, a reverse scanning control voltage, and an output voltage of a turn-on voltage terminal, wherein the forward and reverse scanning circuit of each of the intermediate stage scanning driving units receives the forward scanning control voltage and the reverse scanning control voltage, wherein the forward and reverse scanning circuit of the last stage scanning driving unit receives the forward scanning control voltage, the reverse scanning control voltage, the output voltage of the turn-on voltage terminal, and the output voltage of a turn-off voltage terminal;
• an input circuit, connected to the forward and reverse scanning circuit and configured to receive a first clock signal and a second clock signal opposite to the first clock signal in phase and to charge a pull-up control signal point;
• a latch circuit, connected to the input circuit and configured to receive the first clock signal and the second clock signal and to latch a signal of the pull-up control signal point;
• an output circuit, connected to the latch circuit and configured to receive a third clock signal and generate a scanning driving signal in response to the third clock signal and the signal of the pull-up control signal point;
• and
• a reset circuit, connected to the latch circuit and configured to receive reset signals and reset the pull-up control signal points.
