A vehicle interior system is provided. The vehicle interior system includes a back structure that further includes one or more display devices for a vehicle user. A transparent cover material is attached to the back structure. The vehicle interior system includes a collapsible energy-absorbing support for attaching the back structure to a frame of the vehicle. The collapsible energy-absorbing support is configured to dissipate kinetic energy via plastic deformation. In particular embodiments, the collapsible energy-absorbing support comprises a hollow tube or a formed rectangular plate.

A vibration device includes a base substrate made of silicon and having a first surface and a second surface facing away from the first surface, a lid bonded to the base substrate, a vibrator disposed at the first surface of the base substrate and accommodated in a space between the base substrate and the lid, and a thermistor element disposed at the base substrate.

Provided is a head-up display which projects an image on a windshield and forms a virtual image visually recognizable by a viewer. The head-up display includes a display element which displays the image and a projection optical system which guides the image displayed by the display element to the windshield and forms the virtual image. The projection optical system includes at least two mirrors each having a reflective surface with a concave profile. The windshield has a curvature radius Rx in the right-left direction of the windshield which satisfies 0.05<EBx/Rxmax<0.50, where EBx denotes an eye box size in an X direction in which the virtual image is visually recognizable by the viewer, and Rxmax denotes a maximum value of Rx in an effective ray area of the windshield.

The invention is a robust lensless instrument cluster configured for installation in a vehicle. The instrument cluster comprises an outer case, a PCB and lighting structure, an inner frame, an optical bonding assembly, halo lighting portions, a seamless display comprising tell-tale indicators and gauges, and an outer visor. The instrument cluster further comprises a plurality of LEDs for compartmentalized and indirect lighting of the tell-tale indicators on the seamless display and the halo lighting portions around the edges of the seamless display. Because the instrument cluster is lensless and otherwise exposed to the environment, it comprises a seal system to prevent the ingress of water and dust into the interior components.

A head-up display for a vehicle in which an assembly structure of a screen and a picture generation unit (PGU) is reinforced. The head-up display for a vehicle according to one embodiment includes a lower case embedded with a board assembly, and a screen connected to the lower case in a plurality of directions and snap-fit-coupled to the lower case by passing through the board assembly in at least one direction.

The present invention aims to provide a luminescent display system capable of safely and easily displaying information at a predetermined luminance over a wide area, and a head-up display including the luminescent display system. Provided is a luminescent display system including: a luminescent resin film containing a thermoplastic resin and a luminescent material; and two or more light sources each configured to emit a light beam of excitation wavelength for the luminescent material, the luminescent resin film and two or more light sources being placed such that the light beams emitted from the light sources at least partly overlap on the luminescent resin film.
