Title:
DRIVING VOLTAGE POLARITY INVERSION METHOD AND CIRCUIT FOR LIQUID CRYSTAL PANEL, AND LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2022/116302
Kind Code:
A1
Abstract:
Disclosed are a driving voltage polarity inversion method and circuit for a liquid crystal panel, and a liquid crystal panel. The method comprises: dividing gate lines into X consecutive gate line groups; for a gate line group, successively turning on gate line rows to which first data voltage signals are applied; and after the first data voltage signals are loaded to pixel units on the gate line rows that are turned on, successively turning on gate line rows to which second data voltage signals are applied, and loading, to pixel units on the gate line rows that are turned on, second data voltage signals having polarities opposite to those of the first data voltage signals.
