Title
(EN) LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) PANNEAU D'AFFICHAGE À CRISTAUX LIQUIDES ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 液晶显示面板及液晶显示装置
Abstract
(EN) A liquid crystal display panel (100). A micro-lens array (50), a black matrix layer array (40), and a detector array (60) are arranged in sequence between a cover plate (10) and an array substrate (30). More interference light is filtered out by means of the cooperation of the micro-lens array (50) and the black matrix layer array (40), so that most of the light incident into the detector array (60) is fingerprint reflected light, improving the accuracy of fingerprint recognition. Also provided is a liquid crystal display device (200) comprising the liquid crystal display panel (100).
(FR) La présente invention concerne un panneau d'affichage à cristaux liquides (100). Un ensemble de microlentilles (50), un ensemble de couches de matrice noire (40) et un ensemble de détecteurs (60) sont agencés les uns à la suite des autres entre une plaque de recouvrement (10) et un substrat d'ensemble (30). Davantage de lumière d'interférence est filtrée au moyen de la coopération de l'ensemble de microlentilles (50) et de l'ensemble de couches de matrice noire (40), de telle sorte que la majeure partie de la lumière incidente dans l'ensemble de détecteurs (60) est la lumière réfléchie par l'empreinte digitale, ce qui améliore la précision de la reconnaissance d'empreintes digitales. La présente invention concerne également un dispositif d'affichage à cristaux liquides (200) comprenant le panneau d'affichage à cristaux liquides (100).
(ZH) 一种液晶显示面板(100),通过在盖板(10)和阵列基板(30)之间依次设置微透镜阵列(50)、黑矩阵层阵列(40)和探测器阵列(60),利用微透镜阵列(50)和黑矩阵层阵列(40)的配合滤除较多的干扰光,使得射入至探测器阵列(60)中的光绝大部分均为指纹反射光,提高指纹识别的准确率。还提供一种包括该液晶显示面板(100)的液晶显示装置(200)。
