A scanning drive circuit comprises a pull-up control module (201), a pull-up module (202), a pull-down module (203), a pull-down maintaining module (204), a download module (205) and a bootstrap capacitor (206). When the pull-up control module (201) generates a scanning signal, the pull-up control module (201) and the pull-down maintaining module (204) avoid electric leakage through a constant-voltage high level (DCH), and the pull-down module (203) avoids electric leakage through a scanning signal at the same level (G(N)). The scanning drive circuit can avoid electric leakage very well. |
