Title (EN) DISPLAY DEVICE AND LIGHT GUIDING PANEL
(FR) DISPOSITIF D'AFFICHAGE ET PANNEAU DE GUIDAGE DE LUMIÈRE
(JA) 表示装置及び導光板
Abstract:
(EN) A display device comprises: a light guiding panel 2 with one lateral face formed as a plane of incidence 2a; multiple light sources (3-1 to 3-4) respectively corresponding to multiple displayable patterns; and a control unit 6 for controlling the switching on and off of each of the multiple light sources. The light guiding panel 2 has: first planes of reflection (2d, 2e), formed on another lateral face of the light guiding panel 2, for reflecting and changing the travel direction of light which is emitted from a first light source and enters the light guiding panel 2 through the plane of incidence 2a; and multiple prisms 11 formed on one face 2b of the light guiding panel so as to oppose light which is emitted from a light source corresponding to a pattern, enters the light guiding panel 2 through the plane of incidence 2a, and travels towards the pattern, the prisms reflecting the light so as to cause the exit thereof through another face 2c of the light guiding panel.
(FR) L’invention concerne un dispositif d'affichage comprenant : un panneau de guidage de lumière (2) dont une face latérale est formée comme un plan d'incidence (2a) ; de multiples sources de lumière (3-1 à 3-4) correspondant respectivement à de multiples motifs affichables ; et une unité de commande (6) permettant de commander l’activation et la désactivation de chacune des multiples sources de lumière. Le panneau de guidage de lumière (2) comprend : des premiers plans de réflexion (2d, 2e), formés sur une autre face latérale du panneau de guidage de lumière (2), permettant de réfléchir et de modifier la direction de déplacement de la lumière qui est émise par une première source de lumière et qui pénètre dans le panneau de guidage de lumière (2) par le plan d'incidence (2a) ; et de multiples prismes (11) formés sur une face (2b) du panneau de guidage de lumière de façon à s'opposer à la lumière qui est émise par une source de lumière correspondant à un motif, pénètre dans le panneau de guidage de lumière (2) par le plan d'incidence (2a) et se déplace vers le motif, les prismes réfléchissant la lumière de façon à provoquer sa sortie par une autre face (2c) du panneau de guidage de lumière.
(JA) 表示装置は、側面の一つが入射面2aとして形成される導光板2と、表示可能な複数のパターンのそれぞれに対応する複数の光源(3-1~3-4)と、複数の光源の点灯及び消灯を制御する制御部6とを有する。導光板2は、導光板2の他の側面に形成された、第1の光源から発して入射面2aから導光板2内に入射した光を反射して、その光の伝搬方向を変える第1の反射面(2d、2e)と、導光板の一方の面2bに形成された、パターンに対応する光源から発して入射面2aから導光板2内に入射し、かつ、そのパターンへ向かう光と対向し、その光を導光板の他方の面2cから出射させるように反射する複数のプリズム11とを有する。
