Title
(EN) DRIVE METHOD FOR DISPLAY PANEL
(FR) PROCÉDÉ DE COMMANDE POUR PANNEAU D'AFFICHAGE
(ZH) 显示面板的驱动方法
Abstract
(EN)
A drive method for a display panel, the drive method comprising: making a first multiplexed signal, second multiplexed signal, third multiplexed signal, fourth multiplexed signal, fifth multiplexed signal and sixth multiplexed signal sequentially produce a high level pulse according to a preset sequence during each first row period of a 2i-1th multiplexing period, and making the first multiplexed signal, second multiplexed signal, third multiplexed signal, fourth multiplexed signal, fifth multiplexed signal and sixth multiplexed signal sequentially produce a high level pulse according to a sequence which is the reverse of the preset sequence during each second row period of the 2ith multiplexing period, thereby eliminating the streaky sensation in an image displayed by a display panel and improving the display quality.
(FR)
L'invention concerne un procédé de commande pour un panneau d'affichage, le procédé de commande consistant à : amener un premier signal multiplexé, un deuxième signal multiplexé, un troisième signal multiplexé, un quatrième signal multiplexé, un cinquième signal multiplexé et un sixième signal multiplexé à produire séquentiellement une impulsion de haut niveau selon une séquence prédéfinie pendant chaque première période de rangée d'une 2i-1 ième période de multiplexage, et amener le premier signal multiplexé, le deuxième signal multiplexé, le troisième signal multiplexé, le quatrième signal multiplexé, le cinquième signal multiplexé et le sixième signal multiplexé à produire séquentiellement une impulsion de haut niveau selon une séquence qui est l'inverse de la séquence prédéfinie pendant chaque deuxième période de rangée de la 2i ème période de multiplexage, ce qui permet d'éliminer la sensation de stries dans une image affichée par un panneau d'affichage et d'améliorer la qualité d'affichage.
