Title (EN) LIQUID CRYSTAL DISPLAY DEVICE INCORPORATING OPTICAL SENSOR
(FR) DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES COMPRENANT UN CAPTEUR OPTIQUE
(JA) 光センサ素子内蔵の液晶表示装置
Abstract: front page image
(EN)A liquid crystal display device (1) incorporates an optical sensor element (20) for detecting the position of an object. The optical sensor element (20) comprises: an insulating layer (25); a photonic crystal structure (24) constituted by disposing a plurality of column shaped dielectric rods (26) that are covered by the insulating layer (25) and have a refractive index that differs from the insulating layer (25); an i-type semiconductor (23b) disposed beneath the photonic crystal structure (24); an insulating layer (22) on which the i-type semiconductor (23) is laminated; and a shielding layer on which the insulating layer (22) is laminated. Thus, a liquid crystal display device provided with an optical sensor that efficiently converts light to an electrical signal is provided.
(FR)Le dispositif d'affichage à cristaux liquides (1) selon l'invention incorpore un élément capteur optique (20) servant à détecter la position d'un objet. L'élément capteur optique (20) comprend : une couche isolante (25) ; une structure de cristal photonique (24) constituée en disposant une pluralité de baguettes diélectriques en forme de colonnes (26) qui sont couvertes par la couche isolante (25) et ont un indice de réfraction différent de celui de la couche isolante (25) ; un semi-conducteur de type i (23b) disposé sous la structure de cristal photonique (24) ; une couche isolante (22) sur laquelle est stratifié le semi-conducteur de type i (23) ; et une couche de blindage sur laquelle est stratifiée la couche isolante (22). Ainsi, la présente invention concerne un dispositif d'affichage à cristaux liquides comportant un capteur optique qui convertit efficacement la lumière en un signal électrique.
(JA) 液晶表示装置(1)は、対象物の位置を検知するための光センサ素子(20)を内蔵し、光センサ素子(20)は、絶縁層(25)と、絶縁層(25)に覆われており、絶縁層(25)とは異なる屈折率を有する柱状の誘電体ロッド(26)が複数配されて構成されているフォトニック結晶構造(24)と、フォトニック結晶構造(24)の下方に配されているi型半導体(23b)と、i型半導体(23)が積層されている絶縁層(22)と、絶縁層(22)が積層されている遮光層とを備えている。これにより、効率よく、光を電気信号に変換する光センサ素子を備えた液晶表示装置を提供する。
