Title
(EN) DISPLAY PANEL DRIVING METHOD, SYSTEM, AND DISPLAY DEVICE
(FR) PROCÉDÉ D'ENTRAÎNEMENT DE PANNEAU D'AFFICHAGE, SYSTÈME ET DISPOSITIF D'AFFICHAGE

Abstract
(EN)
A display panel (401) driving method, a system (10), and a display device (40). When the pixel voltage of a basic pixel unit in the display panel (401) is less than a minimum value of a preset threshold voltage range, a precharge time in a scan signal output by scan lines (G1-G6) is increased, and if the pixel voltage is greater than a maximum value of the preset threshold voltage range, the precharge time in the scan signal output by the scan lines (G1-G6) is decreased.
(FR)
La présente invention concerne un procédé d'entraînement de panneau d'affichage (401), un système (10) et un dispositif d'affichage (40). Lorsque la tension de pixel d'une unité de pixel de base dans le panneau d'affichage (401) est inférieure à une valeur minimale d'une plage de tension de seuil prédéfinie, un temps de précharge dans un signal de balayage délivré par des lignes de balayage (G1-G6) est augmenté, et si la tension de pixel est supérieure à une valeur maximale de la plage de tension de seuil prédéfinie, le temps de précharge dans le signal de balayage délivré par les lignes de balayage (G1-G6) est diminué.
(ZH)
一种显示面板(401)的驱动方法、系统(10)及显示装置(40)中,当显示面板(401)中的原像素单元的像素电压小于预设阈值电压范围的下限值,则增加扫描线(G1-G6)输出的扫描信号中的预充电时间,若像素电压大于预设阈值电压范围的上限值,则降低扫描线(G1-G6)输出的扫描信号中的预充电时间。
