Title
(EN) LIQUID CRYSTAL DISPLAY PANEL AND DISPLAY APPARATUS
(FR) ÉCRAN D'AFFICHAGE À CRISTAUX LIQUIDES ET APPAREIL D'AFFICHAGE

Abstract
(EN)
Provided are a liquid crystal display panel (100, 101, 102, 103) and a display apparatus (1000). When no voltage is applied between electrode layers of an under-screen camera area (CUP, CUP’) of a liquid crystal display panel (100, 101, 102, 103), the major axis direction of a plurality of liquid crystal molecules (51, 51’) is parallel to a first substrate (10) and a second substrate (11); and when a first voltage is applied between the electrode layers, the major axis direction of the plurality of liquid crystal molecules (51, 51’) is perpendicular to the first substrate (10) or the second substrate (11). By means of a special electrode design of the under-screen camera area (CUP, CUP’), the plurality of liquid crystal molecules (51, 51’) in the under-screen camera area (CUP, CUP’) stand vertically, thereby reducing an effective optical path difference.

L'invention concerne un écran d'affichage à cristaux liquides (100, 101, 102, 103) et un appareil d'affichage (1000). Lorsqu'aucune tension n'est appliquée entre des couches d'électrode d'une zone de caméra sous-écran (CUP, CUP') d'un écran d'affichage à cristaux liquides (100, 101, 102, 103), la direction de grand axe d'une pluralité de molécules de cristaux liquides (51, 51') est parallèle à un premier substrat (10) et un second substrat (11) ; et lorsqu'une première tension est appliquée entre les couches d'électrode, la direction d'axe principal de la pluralité de molécules de cristaux liquides (51, 51') est perpendiculaire au premier substrat (10) ou au second substrat (11). Au moyen d'une conception d'électrode spéciale de la zone de caméra sous-écran (CUP, CUP'), la pluralité de molécules de cristaux liquides (51, 51') dans la zone de caméra sous-écran (CUP, CUP') se dressent verticalement, ce qui permet de réduire une différence de trajet optique effective.

一种液晶显示面板(100,101,102,103)及显示装置(1000)。在液晶显示面板(100,101,102,103)的屏下摄像头区(CUP,CUP')的电极层之间未施加电压时,多个液晶分子(51,51')的长轴方向与第一基板(10)及第二基板(11)平行,在电极层之间施加第一电压时,多个液晶分子(51,51')的长轴方向垂直于第一基板(10)或第二基板(11)。屏下摄像头区(CUP,CUP')通过特殊电极设计,使屏下摄像头区(CUP,CUP')的多个液晶分子(51,51')垂直站立,减小有效光程差。
