Provided is a scan driving circuit (10) for use in performing a driving operation on cascaded scan lines. The driving circuit (10) comprises a pull-down control module (11) used for receiving a scan signal (G_N-1) of an upper level or a scan signal (G_N+1) of a lower level and generating a corresponding scan level signal; a pull-down module (12) used for pulling down a scan signal (G_N) of the scan lines; a reset control module (13) used for receiving a clock signal (CK_N-1) of the upper level or a clock signal (CK_N+1) of the lower level and generating a reset signal for the corresponding scan lines; a reset module (14), used for pulling up the scan signal (G_N) of the scan lines on the basis of the reset signal; a download module (15) used for generating and transmitting a clock signal (CK_N) and a pull-down control signal (ST_N) of the present level on the basis of the scan signal (G_N) of the scan lines; also comprises a first bootstrapping capacitor (C1), a constant voltage low-level source (VGL), and a constant voltage high-level source (VGH). The scan driving circuit (10) has a simple overall structure and reduced energy consumption. |
