Title (EN) DISPLAY PANEL AND MANUFACTURING METHOD THEREOF
(FR) PANNEAU D'AFFICHAGE ET SON PROCÉDÉ DE FABRICATION
(ZH) 显示面板及其制作方法
Abstract:
(EN) Provided are a display panel and a manufacturing method thereof. Matrix electrodes (15) corresponding to black matrices (12) are disposed at one side of a color filter substrate (10) close to a liquid crystal layer (30). Since the matrix electrodes (15) are in signal connection with common electrodes (25), no voltage difference exists between the matrix electrodes (15) and the common electrodes (25). Accordingly, the liquid crystal layer (30) located between the matrix electrodes (15) and the common electrodes (25) of an array substrate (20) does not rotate either in a conduction state or in a nonconduction state and remains in a non-optically transparent state, such that light beams of adjacent pixels in an LTPS display panel do not interfere with each other, thereby eliminating color shift of the panel at a wide angle of view, and improving display quality of the panel.
(FR) L'invention concerne un panneau d'affichage et son procédé de fabrication. Des électrodes matricielles (15) correspondant à des matrices noires (12) sont disposées sur un côté d'un substrat de filtre coloré (10) proche d'une couche de cristaux liquides (30). Étant donné que les électrodes matricielles (15) sont en connexion de signal avec des électrodes communes (25), aucune différence de tension n'existe entre les électrodes matricielles (15) et les électrodes communes (25). En conséquence, la couche de cristaux liquides (30) située entre les électrodes matricielles (15) et les électrodes communes (25) d'un substrat matriciel (20) ne pivote pas soit dans un état de conduction soit dans un état de non conduction et reste dans un état non optiquement transparent, de telle sorte que des faisceaux de lumière de pixels adjacents dans un panneau d'affichage à silicium polycristallin à basse température (LTPS) n'interfèrent pas les uns avec les autres, ce qui élimine un décalage de couleur du panneau à un grand angle de vision, et améliore la qualité d'affichage du panneau.
(ZH) 一种显示面板及其制作方法,通过在彩膜基板(10)上靠近液晶层(30)的一侧设置与黑色矩阵(12)相对应的矩阵电极(15),由于矩阵电极(15)与公共电极(25)信号连接,因此矩阵电极(15)和公共电极(25)之间不存在电压差,无论在通电和不通电状态下,位于矩阵电极(15)与阵列基板(20)的公共电极(25)之间的液晶层(30)都不会发生偏转,一直呈不透光状态,使得面板相邻像素之间的光线不会产生干扰,消除了面板的大视角色偏,改善LTPS显示面板的显示品质。
