Title
(EN) VEHICLE DASHBOARD, CONTROL METHOD THEREFOR AND COLOR LIGHT-CONTROL DIAPHRAGM
(FR) TABLEAU DE BORD DE VÉHICULE, SON PROCÉDÉ DE COMMANDE ET DIAPHRAGME DE COMMANDE DE LUMIÈRE EN COULEUR

Abstract
(EN) Provided in the present invention are a vehicle dashboard, a control method therefor, and a color light-control diaphragm. The vehicle dashboard comprises a segment code screen, a light-guiding cover, a circuit board and a color light-control diaphragm. The color light-control diaphragm is provided between the segment code screen and the light-guiding cover, and comprises a front protective layer, a rear protective layer, a light-control layer and a UV color pattern layer. The UV color pattern layer is formed by means of UV printing. The light-control layer comprises transparent structures and non-transparent structures, wherein the transparent structures are arranged at intervals along a vertical direction, and the non-transparent structures are provided between the adjacent transparent structures. A line which connects the top front end and the bottom rear end of the transparent structures in a longitudinal section plane is labeled L1, a line which connects the top rear end and the bottom front end is labeled L2, and an included angle α between L1 and L2 is greater than or equal to 55°, and less than or equal to 65°. The segment code screen is a light-emitting plane of the vehicle dashboard. The provision of the color light-control diaphragm not only implements color display for the segment code screen, but also prevents light from being projected onto a front windshield to form a pattern that interferes with the line of sight of a driver.
(FR) La présente invention concerne un tableau de bord de véhicule, son procédé de commande et un diaphragme de commande de lumière en couleur. Le tableau de bord de véhicule comprend un écran de code de segment, un couvercle de guidage de lumière, une carte de circuits imprimés et un diaphragme de commande de lumière en couleur. Le diaphragme de commande de lumière en couleur est disposé entre l'écran de code de segment et le couvercle de guidage de lumière, et comprend une couche de protection avant, une couche de protection arrière, une couche de commande de lumière et une couche de motif de couleur UV. La couche de motif de couleur UV est formée au moyen d'une impression UV. La couche de commande de lumière comprend des structures transparentes et des structures non transparentes, les structures transparentes étant agencées à des intervalles le long d'une direction verticale, et les structures non transparentes étant disposées entre les structures transparentes adjacentes. Une ligne qui relie l'extrémité avant supérieure et l'extrémité arrière inférieure des structures transparentes dans un plan de coupe longitudinale est indiquée L1, une ligne qui relie l'extrémité arrière supérieure et l'extrémité avant inférieure est indiquée L2, et un angle inclus α entre L1 et L2 est supérieur ou égal à 55°, et inférieur ou égal à 65°. L'écran de code de segment est un plan d'émission de lumière du tableau de bord de véhicule. La fourniture du diaphragme de commande de lumière en couleur non seulement met en œuvre un affichage en couleur pour l'écran de code de segment, mais empêche également la lumière d'être projetée sur un pare-brise avant pour former un motif qui interfère avec la ligne de visée d'un conducteur.
(ZH) 本申请提出了一种汽车仪表盘及其控制方法、彩色控光片,汽车仪表盘包括段码屏、导光罩、电路板和彩色控光片,彩色控光片设置于段码屏和导光罩之间,彩色控光片包括前保护层、后保护层、控光层、和UV彩色图案层,UV彩色图案层通过UV打印方式形成,控光层包括透光结构和非透光结构,透光结构沿竖向间隔设置,非透光结构设置于相邻透光结构之间,将透光结构在纵切面内的顶部前端与底部后端的连线记为L1,顶部后端与底部前端的连线记为L2,L1与L2的夹角α大于或等于55度,小于或等于65度,段码屏为汽车仪表盘的出光面。通过设置彩色控光片既能够实现段码屏的彩色显示,又能够避免光线打到前挡玻璃形成干扰驾驶员视线的图案。
