Title (EN) DISPLAY DEVICE AND DRIVING METHOD THEREFOR
(FR) DISPOSITIF D'AFFICHAGE ET PROCÉDÉ DE COMMANDE ASSOCIÉ
(ZH) 显示装置及其驱动方法
Abstract:
(EN) A driving method for a display device, comprising: dividing pixels of a display panel into a plurality of pixel groups, each pixel group comprising an even number of adjacent pixels arranged in sequence (S110); calculating the display hue of each pixel group according to a picture input signal (S120); obtaining a lookup table according to a hue range within which the display hue falls, the lookup table being a correspondence table of color gray-scale values of blue sub-pixels and driving voltage pairs, and the driving voltage pair comprising a high driving voltage and a low driving voltage (S130); obtaining a driving voltage pair according to the average gray-scale value of blue sub-pixels in each pixel group by means of the lookup table (S140); and driving the blue sub-pixels in the corresponding pixel group according to the driving voltage pair (S150).
(FR) L'invention concerne un procédé de commande d'un dispositif d'affichage, comprenant les étapes consistant à : diviser des pixels d'un panneau d'affichage en une pluralité de groupes de pixels, chaque groupe de pixels comportant un nombre pair de pixels adjacents agencés en séquence (S110) ; calculer la teinte d'affichage de chaque groupe de pixels conformément à un signal d'entrée d'image (S120) ; obtenir une table de conversion conformément à une gamme de teintes à l'intérieur de laquelle se situe la teinte d'affichage, la table de conversion étant une table de correspondance de valeurs échelle de gris de couleur de sous-pixels bleus et de paires de tension d'excitation, et la paire de tensions d'excitation comprenant une tension d'excitation élevée et une tension d'excitation faible (S130) ; obtenir une paire de tensions d'excitation conformément à la valeur moyenne d'échelle de gris des sous-pixels bleus dans chaque groupe de pixels au moyen de la table de conversion (S140) ; et exciter les sous-pixels bleus dans le groupe de pixels correspondant conformément à la paire de tensions d'excitation (S150).
(ZH) 一种显示装置的驱动方法,包括:将显示面板上的像素划分为多个像素组,每个像素组包括偶数个依次相邻的像素(S110);根据画面输入信号求取每个像素组的显示色相(S120);根据显示色相所属的色相范围获取查找表,查找表为蓝色子像素的颜色灰阶值与驱动电压对的对应关系表,驱动电压对包括一高一低的驱动电压(S130);根据每个像素组中的蓝色子像素的平均灰阶值利用对应的查找表获取驱动电压对(S140);以及根据驱动电压对对相应的像素组上的蓝色子像素进行驱动(S150)。
