(EN) DRIVING METHOD AND DRIVING SYSTEM FOR DISPLAY PANEL
(FR) PROCÉDÉ D'EXCITATION ET SYSTÈME D'EXCITATION POUR ÉCRAN D’AFFICHAGE
(ZH) 一种显示面板的驱动方法和驱动系统
Abstract
(EN)
A driving method and driving system for a display panel. The driving method comprises: dividing two types of compensation regions by taking a sub-pixel as a unit (S41); and outputting a driving voltage according to the compensation region to which the sub-pixel belongs (S42).
(FR)
La présente invention concerne un procédé d'excitation et un système d'excitation pour un écran d'affichage. Le procédé de commande comprend : la division de deux types de régions de compensation en prenant un sous-pixel en tant qu'unité (S41) ; et la sortie d'une tension d'excitation selon la région de compensation à laquelle le sous-pixel appartient (S42).
