A motor vehicle control panel includes a front face including a control zone; a printed circuit board; at least one electrically conductive capacitive detection element extending along a vertical axis from the rear surface of the front face to an electrical contact zone of the printed circuit board; a light source mounted on the printed circuit board and able to produce a back lighting light beam toward the control zone through the capacitive detection element; the capacitive detection element also comprises at least one rigid tubular part forming a light guide for the light beam and at least one elastic part made in one piece with the rigid tubular part so as to compensate the clearances between the rear surface and the detection element and between the printed circuit board and the detection element.

A display device for a vehicle includes a display unit, a display layer, and a light guide.

A vehicle instrument device includes a housing for attaching a dial plate, a light guide plate housing recess formed in the housing, a light guide plate that is housed in the light guide plate housing recess, and guides illumination light to the dial plate, a claw that fixes the light guide plate to the housing, and a press-fitting rib that is provided in a side surface of the light guide plate, and extends toward a side wall of the light guide plate housing recess. The press-fitting rib includes a tapered portion for increasing a height from a back side to a front side of the light guide plate housing recess and a tapered portion for decreasing a width from the back side to the front side of the light guide plate housing recess.

A vehicular display device includes a facing member having a hole formed therein, an edge-light light guide that guides lights emitted from LEDs, a diffusion member that diffuses light leaking from the edge-light light guide, and a convex light guide having a main part interposed between the diffusion member and the facing member, and a projecting portion projecting into the hole. The lights emitted from the LEDs are guided to the edge-light light guide. The lights guided to the edge-light light guide are diffused by the diffusion member to enter the convex light guide, and leaves from the projecting portion.

This document describes a pedestrian alert system that can draw a driver's attention to a pedestrian on or near a roadway. The described pedestrian alert system can help prevent collisions with pedestrians and other objects in poor visibility environments or when drivers may be distracted. For example, a system can determine a presence of an object in or near a travel path of a host vehicle. The system can also determine the object's position relative to the host vehicle and control a light bar to provide an indication of the object. The indication can have specific characteristics to indicate the object's position relative to the host vehicle. In this way, the described pedestrian alert system can utilize sensors to focus a driver's attention on an object before a potential crash occurs and reduce the number of traffic-related deaths.

An optical system comprises a turning film and a lenticular diffuser. The lenticular diffuser comprises a structured surface comprising a plurality of microstructures each comprising a lenticular prism having linear end sections connected by a blend section separated by a substantially flat land area, wherein the blend section shape is a segment of an ellipse of 2nd, 4th or 6th order polynomial.

A display device including a cover body with a surface facing an observer and a back face facing away from the observer, the cover body has at least two translucent to transparent cover body components which each form a portion of the surface and a portion of the back face; at least one opaque masking layer on the surface facing the observer and which the portion of the surface of the less light transmissive cover body component delimits a first display area to be backlit and the portion of the surface of the more light transmissive cover body component delimits a second display area to be backlit; a support having a plurality of light sources arranged on the side of the cover body facing away from the observer to backlight the display areas; and a frame integrally bonded to the cover body to secure the cover body on the support.

An interior device for a passenger compartment of a transportation vehicle having a light guide to guide light and a viewing side and a rear side opposite to the viewing side, wherein, in the intended installation position of the interior device, light is coupled out from the light guide through the viewing side and the viewing side of the light guide is visible in the passenger compartment, wherein the light guide has at least one fastening element on the rear side, the structure of which predefines a light pattern coupled out on the viewing side, and a transportation vehicle component on which the light guide is held by the fastening element.

A display device displays a virtual image by projecting an image onto a windshield provided on a vehicle and having a curved shape. The display device includes: an image generation device that generates light (image light) representing an image; and a light guide that includes an emission hologram element having a non-rectangular quadrilateral shape. The emission hologram element emits, toward the windshield, the light representing the image and propagating through the light guide.

A display device for the interior of a vehicle comprises light sources, light guides, and holograms. The light guides are arranged next to one another and each has an entrance surface and a reflective area. Each light source emanates light that enters the entrance surface of an associated light. At least one of the holograms is arranged at or in each light guide. The light emanated by each light source enters the entrance surface of the associated light guide in a direction of the reflective area of the associated light guide, is reflected by the reflective area of the associated light guide in a direction of the hologram of the associated light guide, and interacts with the hologram of the associated light guide.
