An instrument cluster is provided with a display panel having a plurality of graphic areas and with a backlighting device arranged behind the display panel for backlighting the graphic areas. The backlighting device has at least one light source and at least one light-guide element, which is provided with a receiving portion facing the light source for directly receiving a light beam and with at least one transmitting portion for transmitting and guiding the light towards at least one of the graphic areas. A cover is provided for shielding rays of light passing through the receiving portion and directed onto the display panel. The cover defines a channel, which has an inlet facing the receiving portion and at least one outlet facing one of the graphic areas. The channel is shaped in such a way as to transmit light indirectly from its inlet to its outlet.

A gauge assembly includes a gauge surface including at least one graphic, which may be a plurality of graphics defining a scale in a generally circular pattern on the gauge surface. The gauge surface has a viewable side. A light guide has a main body portion disposed adjacent to the gauge surface and corresponding to the shape of the gauge surface. The light guide has a plurality of raised tick marks extending from the main body portion. Each tick mark is viewable via a viewing side of the gauge surface. The light guide includes ends that curve away from the gauge surface to receive light. The light guide is configured to provide illumination to the illuminable graphic(s) and the plurality of tick marks.

A vehicle-mounted display panel and a vehicle device are provided. The vehicle-mounted display panel includes a backplate, a first display panel, and a second display panel. A first groove and a second groove are respectively defined on two opposite sides of the backplate. The first display panel and the second display panel are respectively mounted in the first groove and the second groove to improve integration of the first display panel and the second display panel, which is conducive to saving mounting space and realizes lightweight design of vehicles.

A display input device includes a display panel, a knob member that protrudes forward from a display surface of the display panel and is formed of a transparent material, and a film-shaped louver film member that i) is provided between the display surface and the knob member, and ii) includes a plurality of first louvers extending in a first direction and a plurality of second louvers extending in a second direction intersecting the first direction and provided to intersect the plurality of first louvers, in which the louver film member suppresses light traveling toward an outer periphery of the knob member.

A head-up display system for a vehicle having a windshield is provided. The head-up display system includes a first image generation device and an optical system. The first image generation device is configured to provide a first light. The optical system is configured to reflect the first light. A first distance between the first image generation device and the optical system is greater than a second distance between the optical system and the windshield.

The present disclosure relates to a function display for selectively displaying several symbols representing one switching function, respectively, and/or at least two switching states, including a light guide stack which forms a display surface facing towards an observer; wherein the light guide stack is formed from at least planar light guides arranged in an overlaid manner in a stacking direction, which are arranged so as to be spaced apart by a transparent or translucent layer; at least one light source per light guide wherein, further, at least one microstructured symbol area in or on the light guide which is configured, if the light source is activated, to be visible to the observer; a circuit board on which the several light sources are arranged and fixed; a panel fixed to the light guide stack to which the circuit board is fixed while resting against a mounting surface.

A user interface for a vehicle includes a two-dimensional display and an optical faceplate. The display displays information on a display portion. The optical faceplate includes a contact surface, a three-dimensional display surface for displaying information, and an optic light guide material. The optical faceplate is integrated into the display such the areal extension of the display surface and/or the contact surface is smaller than an areal extension of the display. The contact surface receives light emitted from the display. The user interface further includes comprises a device that determines a context according to a state of the vehicle, information that is visible on the display portion and/or the display surface, and/or user input captured by the user interface. The user interface displays contextually dependent information so that the information that is visible on the display portion and on the display surface depend on the determined context.

A main controller of an HUD is configured to: acquire road surface information of a front road surface based on a plurality of measurement points on the front road surface, which is detected by a road surface detection sensor mounted on a vehicle with the HUD and is positioned forward of a traveling direction of the vehicle; calculate, by using the road surface information, a virtual image plane position on a virtual image plane where a virtual image of a display object is displayed, which is a display position of the virtual image for displaying the virtual image along the front road surface; and calculate a display position of a display surface within an image display device, which corresponds to the virtual image plane position, so as to output, to the image display device, a control signal for displaying the display object on the display position of the display surface.
