Title (EN) DISPLAY DEVICE AND LIGHT GUIDE PLATE
(FR) DISPOSITIF D'AFFICHAGE ET PLAQUE DE GUIDAGE DE LUMIÈRE
(JA) 表示装置及び導光板
Abstract:
(EN) This display device comprises a light guide plate 2 which is formed from a transparent plate-shape member and which can display multiple patterns (21-1 to 21-14) representing numbers or symbols, multiple light sources (3-1 to 3-14) which are arranged opposite of incident surfaces (2a-1 to 2a-4) of the light guide plate 2 and which correspond to the patterns, and a control unit 6 which controls lighting and extinction of each light source in accordance with display control information that represents the symbols or numbers to be displayed. On one surface 2b, the light guide plate 2 has multiple prisms 11 arranged along the patterns, and each prism is formed as a triangular pyramid-shape groove, wherein one inclined surface of the triangular pyramid-shape grooves is formed as a reflective surface that reflects, in a direction within a prescribed range of angles, light that is emitted from the light source corresponding to the pattern where the prism is arranged and that has entered the light guide plate.
(FR) L’invention concerne un dispositif d'affichage comprenant : une plaque de guidage de lumière (2) qui est formée à partir d'un élément en forme de plaque transparente et qui peut afficher de multiples motifs (21-1 à 21-14) représentant des nombres ou des symboles ; de multiples sources de lumière (3-1 à 3-14) qui sont disposées en regard des surfaces incidentes (2a-1 à 2a-4) de la plaque de guidage de lumière et qui correspondent aux motifs ; et une unité de commande (6) qui commande l'éclairage et l'extinction de chaque source de lumière en fonction des informations de commande d'affichage qui représentent les symboles ou les nombres à afficher. Sur une surface (2b), la plaque de guidage de lumière (2) comprend de multiples prismes (11) agencés le long des motifs et chaque prisme est conçu comme une rainure ayant la forme d’une pyramide triangulaire, une surface inclinée des rainures en forme de pyramide triangulaire étant conçue comme une surface réfléchissante qui réfléchit, dans une direction dans une plage d'angles prescrite, la lumière qui est émise par la source de lumière correspondant au motif où est disposé le prisme et qui a pénétré la plaque de guidage de lumière.
(JA) 表示装置は、透明な板状の部材で形成され、数字または記号を表す複数のパターン(21-1~21-14)を表示可能な導光板2と、導光板2の入射面(2a-1~2a-4)と対向するように配置され、かつ、各パターンに対応する複数の光源(3-1~3-14)と、表示する記号または数字を表す表示制御情報に従って、各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、その一方の面2bに、各パターンに沿って配列される複数のプリズム11を有し、各プリズムは三角錐状の溝として形成され、三角錐状の溝の一つの斜面が、そのプリズムが配列されるパターンに対応する光源から発して導光板内に入射した光を所定の角度範囲内の方向へ向けて反射する反射面として形成される。
