A display device for a vehicle including: a first display configured to output first light forming first visual information; a second display configured to output second light forming second visual information; a light synthesizing unit located on an advancing path of each of the first light and the second light and forming a first acute angle with the first display and a second acute angle with the second display and configured to transmit therethrough the first light from the first display and reflect the second light from the second display; a first tiltable reflector; a second tiltable reflector; and a driving unit configured to: tilt the first tiltable reflector to form a first angle with the second display so the first tiltable reflector reflects part of the second light directed toward the light synthesizing unit toward a first direction, and tilt the second tiltable reflector to form a second angle with the first display so the second tiltable reflector reflects part of the first light directed toward the light synthesizing unit toward a second direction different from the first direction.

A head-up display system includes an image generating apparatus configured to emit light having a first polarization and including image information; a polarization beam splitter provided on an optical path of the light having the first polarization and configured to transmit the light having the first polarization; a wave plate configured to transmit the light transmitted through the polarization beam splitter while changing a phase of the light; and a mirror configured to reflect the light sequentially transmitted through the polarization beam splitter and the wave plate back to the polarization beam splitter through the wave plate. The polarization beam splitter may reflect light having a second polarization that is different from the first polarization and obtained by transmitting the light reflected by the mirror back through the wave plate.

An HUD system, includes at least one first HUD device, namely an AR-HUD device, with at least one first image source for displaying a first image produced by at least one hologram in a first display section of a display region and at least one second HUD device with at least one second image source for displaying a second image produced using geometric projection optics in a second display section of the display region.

A heads up display system of a vehicle includes a combiner screen having a first substantially transparent substrate defining a first surface and a second surface, a second substantially transparent substrate defining a third surface and a fourth surface. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic material is positioned within the cavity and a transflective layer having a multilayer polymeric film positioned on one of the first and second surfaces, and a projector for projecting light having a first polarization toward the first surface of the first substrate.

A multi-layer display system may include three, four, or more display panels/screens arranged in an overlapping manner, a backlight configured to provide light to the plurality of display screens, and a processing system. The processing system may be configured to display, on a first display screen of the plurality of display screens, a first image including a first gradient area, display, on a second display screen of the plurality of display screens, a second image including a second gradient area, and display, on a third display screen arranged in an overlapping manner between the first display screen and the second display screen, a third image including. The third image may include a third gradient area overlapping at least a portion of the first gradient area displayed on the first display screen and at least a portion of the second gradient area displayed on the second display screen.

An information display apparatus irradiates a transmissive reflection member with light for forming an image so as to make a virtual image of the image visible on the transmissive reflection member. The information display apparatus includes a memory, and a processor coupled to the memory and configured to control, upon a change in depth of a scene position at which to superimpose the virtual image, a degree of change in a part or an entirety of the virtual image to be displayed, differently from a degree of the change in depth.

A display device for a vehicle includes an operating unit which a passenger can operate, and a display unit which displays various types of images based on an operation input at the operating unit. The operating unit and display unit are disposed separated from each other. The operating unit is situated between the eyes of a driver performing the operation input and the display unit, and overlays the display unit on the line-of-sight direction of the driver performing the operation input.

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 multi-eyebox head-up display device and a multilayer combiner are disclosed. The device comprises a projector generates a projected image to a reflector. The reflector generates a reflected image to a multilayer combiner. The multilayer combiner includes at least two superimposed imaging plates, and the semi-reflective surfaces of the superimposed imaging plates are tilted to each other. While the reflected image is projected to the semi-reflective surface of the topmost superimposed imaging plate, the semi-reflective surface of the topmost superimposed imaging plate generates a virtual image. Simultaneously, the reflected image penetrates through the topmost superimposed imaging plate and reaches the lower superimposed imaging plate, and the semi-reflective surface of the lower superimposed imaging plate reflects the light to generate another virtual image. The present invention enables the driver to view the vehicular information at different viewing angles.

When a vehicle stops due to a red light, an image of a scene viewed from a virtual point of view, which moves along a virtual point-of-view moving route, in a virtual line-of-sight direction is displayed on a head-up display. Assuming that a next intersection at which to change lane according to a guidance route is the target intersection, a combination of the virtual point of view and virtual line-of-sight direction is gradually changed from a combination in which a scene is viewed from the point of view of the user in the forward direction of the vehicle to a combination for taking a bird's eye view of a geographic range that includes the current position of the vehicle and then to a combination for taking a bird's eye view of a geographic range that includes the target intersection from a point near the target intersection.
