Title (EN) METHOD FOR OVERDRIVING FOUR-COLOUR PANEL
(FR) PROCÉDÉ DE SURCHARGE D'UN PANNEAU À QUATRE COULEURS
(ZH) 一种四色面板的过驱动方法
Abstract:
(EN) Disclosed is a method for overdriving a four-colour panel. The method comprises: looking for 10% and 90% luminance values in a normalized curve, calculating the difference between R or B and G luminance normalized curves from 10% to 90% segments, determining the overdriven gray-scale voltage value of each R/G in an overdriven gray-scale voltmeter by looking for the minimum value of the difference between luminance normalized curves, and substituting the overdriven target value of the obtained and altered R/G/B into calculation formulas for overdriven target values between gray scales with different W.
(FR) L'invention concerne un procédé de surcharge d'un panneau à quatre couleurs. Le procédé consiste : à rechercher des valeurs de luminance de 10 et 90 % dans une courbe normalisée, à calculer la différence entre des courbes normalisées de luminance R ou B et G depuis des segments de 10 % jusqu'à des segments de 90 %, à déterminer la valeur de tension d'échelle de gris surchargée de chaque R/G dans un voltmètre d'échelle de gris surchargée par recherche de la valeur minimale de la différence entre les courbes normalisées de luminance, et à remplacer la valeur cible surchargée des R/G/B obtenus et modifiés dans des formules de calcul par des valeurs cibles surchargées entre des échelles de gris avec différents W.
(ZH) 公开了一种四色面板的过驱动方法。该方法包括:在归一化曲线图中寻找10%,90%亮度值处,计算10%到90%段的R或B与G亮度归一化曲线的差异,通过寻求亮度归一化曲线差异的最小值,确定过驱动灰阶电压表中每个R/G的过驱动灰阶电压值。将得到的改变后的R/G/B的过驱动目标值带入W不同灰阶之间的过驱动目标值计算公式中。
