Title (EN) LIQUID CRYSTAL DISPLAY APPARATUS
(FR) APPAREIL D’AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶表示装置
Abstract:
(EN) A liquid display apparatus comprises a light source (10) for emitting light having a high directivity, a reflection plate (20) for reflecting the light emitted from the light source (10), a liquid crystal layer (30) allowing the light reflected on the reflection plate (20) to pass through, a position detector (40) for detecting an eye position of the viewer (100) who view a display image and generating position information on the eye position, a reflection angle controller (50) for controlling the rotation angle of the reflection plate (20) based on the position information, and a light emission controller (60) for controlling the light emission intensity and light emission angle of the light source (10) according to the rotation angle of the reflection plate (20). This configuration can effectively radiate the light emitted by the light source (10) to the eyes of the viewer, thereby enhancing the visibility of the liquid crystal apparatus and reducing the power consumption thereof.
(FR) L’invention concerne un appareil d’affichage à cristaux liquides comprenant une source lumineuse (10) pour émettre une lumière de forte directivité, une plaque réfléchissante (20) permettant de réfléchir la lumière émise depuis la source lumineuse (10), une couche de cristaux liquides (30) laissant passer la lumière réfléchie sur la plaque réfléchissante (20), un détecteur de position (40) permettant de détecter une position oculaire du spectateur (100) qui visualise une image d’affichage et permettant de générer des informations de position sur la position oculaire, un contrôleur d’angle de réflexion (50) pour contrôler l’angle de rotation de la plaque réfléchissante (20) sur la base des informations de position, et un contrôleur d’émission de lumière (60) permettant de contrôler l’intensité d’émission de lumière et l’angle d’émission de lumière de la source lumineuse (10) selon l’angle de rotation de la plaque réfléchissante (20). Cette configuration peut irradier de manière efficace la lumière émise par la source lumineuse (10) vers les yeux du spectateur, augmentant ainsi la visibilité de l’appareil à cristaux liquides et réduisant la consommation.
(JA)  本発明の液晶表示装置は、指向性が高い光を発光する光源(10)と、光源(10)が発光した光を反射する反射板(20)と、反射板(20)で反射された光が透過する液晶層(30)と、液晶層(30)の表示画像を見る利用者(100)の目の位置を検出し、目の位置に関する位置情報を生成する位置検出器(40)と、位置情報に基づいて、反射板(20)の回転角を制御する反射角制御部(50)と、反射板(20)の回転角に従って、光源(10)の発光強度と発光角度を制御する発光制御部(60)とを備える。この構成により、光源(10)が発光した光を、無駄なく、利用者の目の方向に射出でき、液晶表示装置の可視性と省電力化を実現できる。
