Title (EN) PIXEL ELECTRODE AND LIQUID CRYSTAL DISPLAY PANEL
(FR) ÉLECTRODE DE PIXEL ET PANNEAU D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 像素电极及液晶显示面板
Abstract:
(EN) A pixel electrode (1) and a liquid crystal display panel; the pixel electrode (1) is provided with a first sealing frame (15) which connects a trunk (11) and ends of all pixel electrode branches (13), and at least one second sealing frame (17) sleeved on the periphery of the first sealing frame (15) and connected to the trunk (11); by means of the first sealing frame (15) and the second sealing frame (17), an electric field at the edge of the pixel electrode (1) is regularized, thus orientation of liquid crystal molecules located at the edge of a sub-pixel is relatively uniform, which may eliminate dark lines at the edges all around the sub-pixels and improve optical transmittance of the liquid crystal display panel; in addition, a new domain is formed between the first sealing frame (15) and the second sealing frame (17), which may further improve the viewing angle of the liquid crystal display panel at low and medium gray levels.
(FR) La présente invention concerne une électrode de pixel (1) et un panneau d'affichage à cristaux liquides ; l'électrode de pixel (1) est pourvue d'un premier cadre d'étanchéité (15) qui relie un tronc (11) et des extrémités de toutes les branches d'électrode de pixel (13), et au moins un second cadre d'étanchéité (17) emmanché sur la périphérie du premier cadre d'étanchéité (15) et relié au tronc (11) ; au moyen du premier cadre d'étanchéité (15) et du second cadre d'étanchéité (17), un champ électrique au bord de l'électrode de pixel (1) est régularisé, ainsi l'orientation des molécules de cristaux liquides située au bord d'un sous-pixel est relativement uniforme, ce qui peut éliminer les lignes sombres au niveau des bords tout autour des sous-pixels et améliorer la transmittance optique du panneau d'affichage à cristaux liquides ; en outre, un nouveau domaine est formé entre le premier cadre d'étanchéité (15) et le second cadre d'étanchéité (17), ce qui peut en outre améliorer l'angle de visualisation du panneau d'affichage à cristaux liquides à des niveaux de gris bas et moyen.
(ZH) 一种像素电极(1)及液晶显示面板,像素电极(1)设置有连接所有像素电极分支(13)的末端和主干(11)的第一封闭框(15)、以及至少一个套设在第一封闭框(15)外围并与主干(11)连接的第二封闭框(17),通过第一封闭框(15)与第二封闭框(17)使得像素电极(1)的边缘电场规整,从而使位于子像素边缘的液晶分子的取向较为均匀一致,能够消除子像素四周边缘的暗纹,提高液晶显示面板的光学穿透率;此外,第一封闭框(15)与第二封闭框(17)两者之间形成一个新畴,能够进一步改善液晶显示面板在中低灰阶下的视角。
