Title: GOA CIRCUIT AND LIQUID CRYSTAL DISPLAY
Abstract:
Disclosed are a GOA circuit and a liquid crystal display. The GOA circuit (10) comprises a plurality of cascaded GOA units (11) and a control module (12). Each GOA unit (11) is used for, when driven by a first stage clock (CK-A1), a second stage clock (CK-A2), a first control clock (CK-B1), and a second control clock (CK-B2), charging a corresponding horizontal scanning line in a display area. The control module (12) is used for controlling, by means of a starting pulse signal (STV), gate driving signals (GATE (1), GATE (M), GATE (N)) on the horizontal scanning lines to be reset to a first level, namely, invalid level, after the GOA circuit (10) simultaneously charges all of the horizontal scanning lines. Generation of a redundant pulse signal before a first gate driving signal (GATE (1)) is output can be avoided, thereby ensuring normal operation of the GOA circuit (10).
