Title (EN) LIGHT GUIDE STRUCTURE AND DISPLAY APPARATUS
(FR) STRUCTURE DE GUIDAGE DE LUMIÈRE ET APPAREIL D'AFFICHAGE
(ZH) 导光结构、显示装置
Abstract:
(EN) Disclosed are a light guide structure (100) and a display apparatus (101). The light guide structure (100) comprises a first substrate (1), a second substrate (3) and at least one optical fibre bundle (5), wherein the first substrate (1) comprises at least one first through hole (2); the second substrate (3) is arranged opposite the first substrate (1) and comprises at least one second through hole (4); each optical fibre bundle (5) comprises a first end and a second end, the first end of each optical fibre bundle (5) is fixed in one first through hole (2), and the second end of the optical fibre bundle (5) is a free end; the distance between the first substrate (1) and the second substrate (3) is adjustable; and at least part of an orthographic projection, on the second substrate (3), of the first through hole (2) overlaps the second through hole (4). By means of the light guide structure (100), a scattering angle of the second end of the optical fibre bundle (5) can be controlled so as to control an emergent angle of light passing through the second end of the optical fibre bundle (5), thus realizing the switching between a wide viewing angle and a narrow viewing angle of the display apparatus (101) and satisfying a user's requirements regarding switching between anti-peeping and display content sharing.
(FR) L'invention concerne une structure de guidage de lumière (100) et un appareil d'affichage (101). La structure de guidage de lumière (100) comprend un premier substrat (1), un second substrat (3) et au moins un faisceau de fibres optiques (5), le premier substrat (1) comprenant au moins un premier trou traversant (2) ; le second substrat (3) est disposé en regard du premier substrat (1) et comprend au moins un deuxième trou traversant (4) ; chaque faisceau de fibres optiques (5) comprend une première extrémité et une seconde extrémité, la première extrémité de chaque faisceau de fibres optiques (5) est fixée dans un premier trou traversant (2), et la seconde extrémité du faisceau de fibres optiques (5) est une extrémité libre ; la distance entre le premier substrat (1) et le second substrat (3) est réglable ; et au moins une partie d'une projection orthographique, sur le second substrat (3), du premier trou traversant (2) chevauche le second trou traversant (4). Au moyen de la structure de guidage de lumière (100), un angle de diffusion de la seconde extrémité du faisceau de fibres optiques (5) peut être commandé de façon à commander un angle émergent de lumière traversant la seconde extrémité du faisceau de fibres optiques (5), réalisant ainsi la commutation entre un angle de vision large et un angle de vision étroit de l'appareil d'affichage (101) et satisfaisant les exigences d’un utilisateur concernant la commutation entre un mode de partage de contenu d'affichage et un mode anti-observation.
(ZH) 一种导光结构(100)、显示装置(101)。该导光结构(100)包括第一基板(1)、第二基板(3)和至少一个光纤束(5);第一基板(1)包括至少一个第一通孔(2);第二基板(3)与第一基板(1)相对设置且包括至少一个第二通孔(4);每个所述光纤束(5)包括第一端和第二端,每个光纤束(5)的第一端固定于一个第一通孔(2)内,光纤束(5)的第二端为自由端;第一基板(1)和第二基板(3)之间的距离可调;第一通孔(2)在第二基板(3)上的至少部分正投影与第二通孔(4)重合。利用该导光结构(100)可以控制光纤束(5)的第二端的散射角度,以控制光经由光纤束(5)的第二端的出射角度,实现显示装置(101)的宽视角和窄视角变之间的切换,满足用户对防窥和显示内容共享的转换需求。
