An operation input apparatus for a vehicle, comprising: a touch panel display that extends in a vehicle width direction; an instrument panel that has a flat surface that extends from a position near a lower end of the touch panel display, in a rearward direction of the vehicle; and an operation input unit that is provided in the flat surface, wherein the operation input unit includes one or more button switches, and upper surfaces of the one or more button switches are flush with the flat surface, or are located on a lower side of the vehicle relative to the flat surface.

A head-up display system includes a projector adapted to project an image, a primary reflector, and an exit pupil replicator, the primary reflector adapted to reflect an image projected by the projector to the exit pupil replicator, and the exit pupil replicator adapted to split the projected image into a two-dimensional array of identical projected images having equal intensity.

An optical system includes a light guide member and a prism. The light guide member has: an incident surface on which light is incident; and a first surface and a second surface facing each other. The second surface is a light emergent surface. The prism is provided for the first surface and reflects, toward the second surface, the light passing inside the light guide member. The light guide member includes a direct optical path, along which the light that has entered the light guide member through the incident surface is directly reflected from the prism and allowed to emerge from the second surface.

A head-up display system includes a three-dimensional display device, an optical member, and an accelerometer. The three-dimensional display device includes a display panel, an optical element, and a controller. The display panel displays an image. The optical element defines a traveling direction of image light emitted from the display panel. The optical member reflects the image light from the three-dimensional display device toward a user's eye. The optical member is at a fixed position relative to the three-dimensional display device. The accelerometer detects acceleration of the three-dimensional display device. The controller controls a position of the image on the display panel based on the acceleration.

A head-up display system includes a first projection module, a second projection module, and a first reflective optical element. The first projection module projects a first image. The second projection module projects a second image. The first reflective optical element reflects at least a part of the first image and at least a part of the second image. The first projection module includes a first display panel that displays the first image and projects the first image toward the first reflective optical element. The second projection module includes a second display panel that displays the second image, and an optical system that directs the second image toward the first reflective optical element.

A method for operating a display arrangement of a motor vehicle, which includes at least two display devices each with a display surface. A visible display content can be shifted here three-dimensionally between two display planes. A detection and evaluation device of an operator control device carries out: acquisition of an operator control action by a touch-sensitive operator control surface, preferably a pulling and/or shifting gesture, and of its extension direction, and, on the basis of the determined extension direction, determination of a data set which describes the display content, as well as determination of a predetermined shift of a virtual image of the display content from one of the display planes to the other of the display planes.

A carbon decorative panel includes a clear decoration body and a carbon color layer. The clear decoration body has a main body 10a transmitting light and includes a carbon-toned irregular surface provided on the opposite side to the viewer side of the main body and having a carbon-toned pattern formed with protrusions and depressions. The carbon color layer is laminated on the carbon-toned irregular surface, includes a reflective surface reflecting incident light transmitted through the clear decoration body, and is colored in a carbon color.

The head-up display device projects a virtual image and includes: an image processor that processes an image to be displayed as a virtual image; an image display that projects the processed image; and a display controller that controls the displaying of the image display. The image display includes: a projector that projects an image; a diffusion plate that forms the image projected by the projector; and a lens that guides the image formed by the diffusion plate. The diffusion plate is constituted by a plurality of functional liquid crystal films that are located at different distances from the lens. The display controller is configured such that, by controlling a transmissive state and a white state of each functional liquid crystal film, the position and distance for displaying the virtual image can be changed.

Vehicle projection assemblies are described. In particular, vehicle projection assemblies within a housing including a projection module, and selective reflective polarizing element are described. Particular selective reflective polarizing elements may enable advantageous configurations for such vehicle projection assemblies.

A head up display may include a combiner having a semi-transparent mirror to reflect light projected by a head up display light source. A dimmable element may be disposed adjacent to the combiner and opposite the semi-transparent mirror. The dimmable element may be configured to reduce the transmission of light reflected by the combiner through the dimmable element. The dimmable element may include a control system configured to reduce the transmission of light reflected by the combiner according to a plurality of light transmission reduction steps and may include a feedback control system configured to adjust the transmission of light through the dimmable element based on at least a light sensor and a light source measuring light transmission through the dimmable element.
