Title
(EN) DRIVE METHOD FOR DISPLAY PANEL
(FR) PROCÉDÉ D'EXCITATION 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: m multiplexing signals starting to produce high level pulses sequentially according to a preset sequence at the starting time of a 2i-1th row period, wherein the high level pulse of the last multiplexing signal to produce a high level pulse in the 2i-1th row period continues until the ending time of the 2i-1th row period (S2); and the m multiplexing signals starting to produce high level pulses sequentially according to a sequence which is opposite to the preset sequence at the starting time of a 2ith row period, wherein the high level pulse of the last multiplexing signal to produce a high level pulse in the 2ith row period continues until the ending time of the 2ith row period (S3). Thus, the number of times which the level of multiplexing signals changes within a frame period is reduced, which reduces power consumption.

Un procédé d'excitation pour un panneau d'affichage, le procédé d'excitation comprenant: m signaux de multiplexage commençant à produire des impulsions de haut niveau séquentiellement selon une séquence prédéfinie au moment de démarrage d'une 2i-1 ième période de rangée, l'impulsion de haut niveau du dernier signal de multiplexage pour produire une impulsion de haut niveau dans la 2i-1 ème période de rangée continuant jusqu'à ce que le temps de fin de la 2i-ième période de rangée (S2); et les m signaux de multiplexage commençant à produire des impulsions de haut niveau séquentiellement selon une séquence qui est opposée à la séquence prédéfinie au moment du démarrage d'une 2 ième période de rangée, l'impulsion de haut niveau du dernier signal de multiplexage servant à produire une impulsion de haut niveau dans la 2 ième période de rangée continuant jusqu'à ce que le temps de fin de la 2 ième période de rangée (S3). Ainsi, le nombre de fois où le niveau de signaux de multiplexage change dans une période de trame est réduit, ce qui réduit la consommation d'énergie.
