Title
(EN) LIQUID CRYSTAL PANEL AND DRIVE METHOD THEREOF
(FR) PANNEAU À CRISTAUX LIQUIDES ET SON PROCÉDÉ DE COMMANDE
(ZH) 液晶显示面板及其驱动方法
Abstract
(EN)
A liquid crystal panel and a drive method thereof. A gate drive unit (41) alternately inputs a scanning signal to multiple scanning lines (G~G2k) at multiple lines, and a source drive unit (42) alternately inputs a gray-scale voltage to multiple data lines (D1~D2m) extending along a column direction. The liquid crystal panel and the drive method thereof avoid the inconsistent charging efficiency of pixel units caused due to the voltage drop of a signal line.
(FR)
L'invention concerne un panneau à cristaux liquides et son procédé de commande. Une unité de commande de grille (41) entre de manière alternée un signal de balayage dans de multiples lignes de balayage (G~G2k) au niveau de multiples lignes, et une unité de commande de source (42) entre de manière alternée une tension en niveau de gris dans de multiples lignes de données (D1~D2m) s'étendant le long d'une direction de colonne. Le panneau à cristaux liquides et son procédé de commande évitent l'efficacité de charge incohérente d'unités de pixel provoquée par la chute de tension d'une ligne de signal.
(ZH)
一种液晶显示面板及其驱动方法,栅极驱动单元(41)向多条各行扫描线(G~G2k)之间间隔地输入扫描信号;源极驱动单元(42)向多条沿列方向延伸的数据线(D1~D2m)间隔地输入灰阶电压。这种液晶显示面板及其驱动方法,避免了由于信号线存在的电压降而造成的对像素单元的充电效率不一致的问题。
