Abstract

Official abstract text for this publication.

A scan driving circuit is disclosed, and the scan driving circuit has a pull-up control module, a pull-up module, a pull-down module, a pull-down maintaining module, a down-stream module, a bootstrap capacitor, and a constant-voltage low-level source; the constant-voltage low-level source includes a first constant-voltage low-level source which provides a first low-level and a second constant-voltage low-level source which provides a second low-level; and an absolute value of the first low-level is smaller than an absolute value of the second low-level. The reliability of the scan driving circuit is thus improved.

First claim

Opening claim text (preview).

What is claimed is: 1. A scan driving circuit, executing a driving operation for cascaded scan lines, comprising: a pull-up control module receiving a previous-level down-stream signal, and generating a scan level signal corresponding to one of the scan lines according to the previous-level down-stream signal; a pull-up module pulling up a scan signal of the corresponding scan line according to the scan level signal and a present-level clock signal; a pull-down module pulling…
