Title (EN) DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE
(JA) 表示装置
Abstract:
(EN) This display device comprises: a light guide plate (2) that is formed of a transparent member, can display one or more patterns, and has one or more incident surfaces; and a plurality of light sources (3-1 to 3-3) that are disposed so as to face any of the one or more incident surfaces and that emit light beams of mutually different colors. The light guide plate (2) includes a plurality of prisms (11) that are arrayed along a pattern (21) on one surface of the light guide plate and that reflect light beams, which have been emitted respectively from the plurality of light sources, have passed though the one or more incident surfaces, and have entered inside the light guide plate, so as to be outputted from another surface of the light guide plate. For each of the plurality of light sources (3-1 to 3-3), the arrangement density of the prisms that reflect the light beam from each light source, from among the plurality of prisms (11), is set in accordance with the color of the pattern (21).
(FR) L’invention concerne un dispositif d'affichage qui comprend : une plaque de guidage de lumière (2) constituée d'un élément transparent, pouvant afficher au moins un motif, et comportant au moins une surface incidente ; et une pluralité de sources de lumière (3-1 à 3-3) qui sont disposées de manière à faire face à n’importe laquelle desdites surfaces incidentes et qui émettent des faisceaux lumineux de couleurs différentes les unes des autres. La plaque de guidage de lumière (2) comprend une pluralité de prismes (11) qui sont disposés en réseau le long d'un motif (21) sur une surface de la plaque de guidage de lumière et qui réfléchissent des faisceaux lumineux qui ont été émis respectivement à partir de la pluralité des sources de lumière, qui ont traversé lesdites surfaces incidentes, et qui ont pénétré à l'intérieur de la plaque de guidage de lumière, de façon à être émis à partir d'une autre surface de la plaque de guidage de lumière. Pour chacune de la pluralité des sources de lumière (3-1 à 3-3), la densité d'agencement des prismes qui réfléchissent le faisceau de lumière à partir de chaque source de lumière, parmi la pluralité de prismes (11), est réglée en fonction de la couleur du motif (21).
(JA) 表示装置は、透明な部材で形成され、少なくとも一つのパターンを表示可能であり、かつ、少なくとも一つの入射面を有する導光板(2)と、少なくとも一つの入射面の何れかと対向するように配置され、かつ、互いに異なる色を持つ光を発する複数の光源(3-1~3-3)とを有する。そして導光板(2)は、導光板の一方の面に、パターン(21)に沿って配列され、複数の光源のそれぞれから発して入射面から導光板内に入射した光を導光板の他方の面から出射させるように反射する複数のプリズム(11)を有し、パターン(21)の色に応じて、複数の光源(3-1~3-3)のそれぞれについて、複数のプリズム(11)のうちのその光源からの光を反射するプリズムの配置密度が設定される。
