A scanning drive circuit (20) used for implementing a drive operation for cascaded scanning lines and having a simple overall structure and low power consumption, comprising a pull-down control module (21), a pull-down module (22), a pull-up module (23), a pull-up maintenance module (24), a bootstrap capacitor (C1), a constant-voltage low power level source and a constant-voltage high power level source; the scanning drive circuit (20) uses a P-type metal-oxide-semiconductor type transistor to control the pull-down control module (21), the pull-down module (22), the pull-up module (23) and the pull-up maintenance module (24). |
