More Information
Summary:A scan driving circuit and a display panel are disclosed. A scan driving unit includes a pull-up control circuit configured for receiving a stage transmission signal of the previous two stages to charge a pull-up control signal node. A first reset circuit receives an input signal, a first clock signal and a second clock signal to reset the pull-up control signal node, wherein the input signal is a DC voltage. A pull-down holding circuit receives a low frequency clock signal and a second low frequency clock signal to hold the electric potential of the pull-up control signal node. A pull-down circuit receives a scan driving signal of the next two stages to pull down the electric potential of the pull-up control signal node. A pull-up circuit receives the first clock signal to output a stage transmission signal and a scan driving signal of the current stage.
