  • Patent number: 10460671
    Abstract: The present application discloses a scanning driving circuit and a display apparatus. The scanning driving circuit includes a scanning signal output terminal; a pull-up circuit controlling the scanning signal output terminal to output a high level scanning signal; a transmission circuit for outputting a stage transmission signal of a current stage; a pull-up control circuit to charge the pull-up control signal point; a pull-down maintaining circuit maintains the low level of the pull-up control signal point and the scanning signal output terminal and releases the high potential of the pull-up control signal point; a bootstrap circuit raises the potential of the pull-up control signal point; a pull-down circuit controls the scanning signal output terminal to output a low level, thereby solving the problem of the large current generated when the display device is turned on and off.
