SCAN DRIVING CIRCUIT AND LCD DEVICE

摘要

A scan driving circuit includes a pull-up assembly, a pull-up control assembly that drives the pull-up assembly, a pull-down maintaining assembly, and a reference low-level signal. The reference low-level signal includes a first reference low-level signal and a second reference low-level signal. When the current scanning line is inactive, the pull-down maintaining assembly controls the reference low-level to be sent to the current scanning line and the output end of the pull-up control assembly according to a pull-down maintaining signal.

主权项

1. A scan driving circuit, comprising:
a pull-up assembly; a pull-up control assembly that drives the pull-up assembly; a pull-down maintaining assembly; and a reference low-level signal comprising a first reference low-level signal and a second reference low-level signal; wherein an output end of the pull-up assembly is coupled to a current scanning line, an output end of the pull-up control assembly is connected to a control end of the pull-up assembly, and the second reference low-level signal is sent to the output end of the pull-up control assembly through the pull-down maintaining assembly, the first reference low-level signal is sent to the current scanning line through the pull-down maintaining assembly, electric potential of the second reference low-level signal is less than electric potential of the first reference low-level signal; when the current scanning line is inactive, the second reference low-level signal is sent to the output end of the pull-up control assembly trough the pull-down maintaining assembly, and the first reference low-level signal is also sent to the current scanning line through the pull-down maintaining assembly.
