Abstract
(EN) A display device and a vehicle. The display device comprises a segment code screen (10), a light control sheet (40), a color film (70), a light guide cover (20), and a circuit board (30). The light control sheet (40) comprises a front protective layer (41), a rear protective layer (42), and a light control layer (43); the light control layer (43) is provided between the front protective layer (41) and the rear protective layer (42), the front protective layer (41) is attached to the rear side face of the segment code screen (10), and the rear protective layer (42) is attached to the front face of the color film (70); the light control layer (43) comprises light-transmitting structures (431) and non-light-transmitting structures (432) which are arranged in a staggered manner in the vertical direction. By providing the light control sheet (40), a pattern which interferes with the sight of a driver due to the fact that light hits the front windshield (200) can be avoided, and driving safety is guaranteed.
(FR) La présente invention concerne un dispositif d'affichage et un véhicule. Le dispositif d'affichage comprend un écran de code de segment (10), une feuille de commande de lumière (40), un film de couleur (70), un couvercle de guide de lumière (20) et une carte de circuit imprimé (30). La feuille de commande de lumière (40) comprend une couche de protection avant (41), une couche de protection arrière (42), et une couche de commande de lumière (43) ; la couche de commande de lumière (43) est disposée entre la couche de protection avant (41) et la couche de protection arrière (42), la couche de protection avant (41) est fixée à la face latérale arrière de l'écran de code de segment (10), et la couche de protection arrière (42) est fixée à la face avant du film coloré (70) ; la couche de commande de lumière (43) comprend des structures de transmission de lumière (431) et des structures de non-transmission de lumière (432) qui sont disposées en quinconce dans la direction verticale. En fournissant la feuille de commande de lumière (40), un motif qui interfère avec la vue d'un conducteur en raison du fait que la lumière frappe le pare-brise avant (200) peut être évité, et la sécurité de conduite est garantie.
(ZH) 一种显示装置及汽车,显示装置包括段码屏(10)、控光片(40)、彩色胶片(70)、导光罩(20)和电路板(30),控光片(40)包括前保护层(41)、后保护层(42)和控光层(43),控光层(43)设置于前保护层(41)和后保护层(42)之间,前保护层(41)与段码屏(10)的后侧面贴合设置,后保护层(42)与彩色胶片(70)的正面贴合设置,控光层(43)包括沿竖向交错设置的透光结构(431)和非透光结构(432)。通过设置控光片(40)能够避免光线打到前挡玻璃(200)形成干扰驾驶员视线的图案,保证驾驶安全。
