The projection display device is configured such that a position of a mirror surface of the first mirror and the second mirror is adjustable in accordance with a position of an eye point of a user so as to project the light toward the projection position that corresponds to the position of the eye point. The shielding plate is provided such that the shieling plate does not interfere with the regular optical path and such that the shielding plate interferes with the different optical path.

A head-up display system for a motor vehicle includes a projection unit for providing a display image; a transparent, holographic optical fiber display panel for outputting, on a display surface, a display image that is coupled into the display panel via a coupling-in region; and a guide device designed to move the display panel between an operational position and a parked position.

The embodiments disclosed in this application describe a displaying system, a displaying method, and a head-up display. The heads-up displaying system includes a display window including a transflective film, an image source emitting light incident on the imaging window, and the light emitted by the image source before reaching the transflective film only comprising s-polarized light. The transflective film is configured to directly reflect a first portion of the s-polarized light emitted from the image source. The transparent substrate reflects a second portion of the s-polarized light, and transmits a third portion of the s-polarized light to the air, the first portion of the s-polarized light, the second portion of the s-polarized light and the third portion of the s-polarized light are all s-polarized light.

There are provided a screen image-displaying laminated glass that reduces the distortion of a projected display image, a method for producing the screen image-displaying laminated glass, and a screen image display system including the screen image-displaying laminated glass. The screen image-displaying laminated glass has a half-mirror film that has a transparent support and that has a selectively reflecting layer which wavelength-selectively reflects light, a first glass plate disposed on one surface of the half-mirror film, and a second glass plate disposed on the other surface of the half-mirror film. The longitudinal directions of bright and dark lines observed by a magic mirror method match each other at the first glass plate, the second glass plate, and the transparent support.

A display device for a vehicle includes: a display, a polarization switching unit, a reflector, and a controller. The polarization switching unit includes a wave plate that can cause emission light of the display to be emitted while changing a polarization direction thereof, and a drive device that can rotate the wave plate between a position of not using polarizing sunglasses and a position of using polarizing sunglasses. The controller rotates the wave plate within a prescribed range, detects luminance values for each fixed rotation angle of the wave plate within a prescribed range from imaging information of an imaging device that transmits a principal component of transmitted light of the wave plate at a position of the eye box, and sets, as a correction angle, a rotation angle of the wave plate corresponding to a maximum luminance value among the luminance values.

An electronic device includes a substrate, an electronic component, a first blocking structure and a packaging layer. The substrate defines a normal direction perpendicular to a surface of the substrate. The electronic component is disposed on the substrate. The first blocking structure is disposed adjacent to a side of the electronic component. The packaging layer is disposed on the electronic component and has a refractive index n at a wavelength of 550 nm. The electronic component has a width W in a first direction perpendicular to the normal direction. A distance H is between a surface of the first blocking structure away from the substrate and the surface of the substrate in the normal direction. A spaced distance P1 is between the surface of the first blocking structure away from the substrate and the electronic component in the first direction. Following relationship is satisfied:

H=n[(P1+W)/tan ].

In an information display apparatus displaying information onto a vehicle, an information display apparatus capable of acquiring a lot of pieces of image information while reducing point-of-view motion of a viewer is provided. An information display apparatus displaying information onto a vehicle includes a first information display apparatus displaying image information of a virtual image by allowing a windshield glass of a vehicle to reflect light, a second information display apparatus acquiring a practical image by scanning the windshield glass with laser light using a MEMS element and a third information display apparatus using an instrument panel of the vehicle.

It is aimed to provide a projection system for projecting signal data on a windscreen or side screens of a motor vehicle cabin. The system comprises a light source arranged for emitting a beam and a housing, to be configured at an elevated position in the cabin. The housing comprising a digital mirror device, the digital mirror device arranged pattern the beam of the light source to project an image on at least a front and side window portion of the cabin. Part of the housing is shaped with a reflective surface that is optically inverse to the cabin window geometry, so that, when the digital mirror device projects a single image on the optical surface, it is imaged on the windscreen and at least one of side windows.

A vehicle display device includes a housing to be mounted on a vehicle and having an opening, a display unit disposed inside the housing and configured to project a display image toward a reflection unit arranged in front of a driver seat through the opening, and a controller configured to cause the display unit to exhibit a range display that defines a maximum range for a display image, upon detection of information indicating a change in the viewpoint of a driver on the vehicle

Vehicle driving assistance systems, methods, and programs display a recommended driving marking superimposed on a real view on a display. The recommended driving marking includes (i) a recommended route marking representing a recommended route, the recommended route being a traveling route with a relatively low likelihood of interference with one or a plurality of obstacles present in a traveling direction of a vehicle; and (ii) a recommended speed marking representing a recommended speed index, the recommended speed index being an index related to a travel speed recommended when the vehicle travels the recommended route. The recommended route marking and the recommended speed marking are displayed so as to be associated with each other.
