A vehicle display system, which is provided in a vehicle, includes a first display device configured to emit a light pattern toward a road surface outside the vehicle; and a second display device located inside the vehicle and configured to display predetermined information toward an occupant of the vehicle such that the predetermined information is superimposed on a real space outside the vehicle.

A display includes a light-guide optical element (LOE) (20) and a projector arrangement (10a) for injecting an image into the LOE so as to propagate within the LOE by internal reflection at a pair of major faces. The image is coupled out from the LOE by a coupling-out arrangement, exemplified here as internal partially-reflecting surfaces (22b). The image is coupled out from the LOE in a direction away from the eye of the observer (24b), and a reflector (30) reflects the coupled-out image back through the LOE (32), towards the eye of the observer (26). Reflector (30) is preferably a selective partial reflector, and may be convex to provide a desired apparent image distance.

This display system includes: a projection device including a phase-modulation-type spatial light modulator element, a light source radiating light to a display part of the element, and a control circuit controlling the element and the light source; and projecting reflection light of the part of the element; and a reflecting mirror reflecting projection light of the device. The control circuit displays, on the part of the element, a first pattern and a second pattern associated with display information having different definition degrees. The reflecting mirror includes a first reflection region causing reflection light of a portion where the first pattern is displayed to enter, and reflecting the light toward a first display region, and a second reflection region causing reflection light of a portion where the second pattern is displayed to enter, and reflecting the light toward a second display region.

Provided is an interlayer film for laminated glass with which double images in laminated glass can be significantly suppressed. The interlayer film for laminated glass according to the present invention is an interlayer film for use in a laminated glass that is a head-up display, the interlayer film has one end, and the other end being at the opposite side of the one end, the other end has a thickness larger than a thickness of the one end, the interlayer film has a region for display corresponding to a display region of the head-up display, and when three regions obtained by equally dividing the region for display into three in a direction connecting the one end and the other end are named a first partial region for display, a second partial region for display, and a third partial region for display in sequence from the one end side, as to partial wedge angle A.sub.x, B.sub.x, and C.sub.x in the first, second, and third partial regions for display, and partial wedge angle φ.sub.x in the region for display satisfy, |A.sub.x−φ.sub.x| is 0.05 mrad or less, |B.sub.x−φ.sub.x| is 0.05 mrad or less, and |C.sub.x−φ.sub.x| is 0.05 mrad or less.

An interlayer film for laminated glass is disclosed which contains a thermoplastic resin and has a portion where the amount of increase in the thickness is increased in a direction from one end to the other end in the region where the thickness is increased, or has a portion where the amount of increase in the thickness is decreased in a direction from one end to the other end in the region where the thickness is increased, and the ten-point average roughness Rz of the surface at a center position of the portion where the amount of increase in the thickness is increased, or the portion where the amount of increase in the thickness is decreased is 20 μm or more.

An optical system includes a light guide member having a light-incident surface, a first surface, a light-emitting surface facing the first surface, a first end surface, a second end surface, a plurality of collimating lenses disposed on the light-incident surface and being arranged along a first direction, and a plurality of prism pieces. The plurality of prism pieces include two or more prism pieces having different inclination angles with respect to the light-incident surface depending on positions of the prism pieces in at least the first direction, and each of the inclination angles of the two or more prism pieces is an angle formed between the first direction and the longitudinal axis of a corresponding prism piece. Each of the inclination angles of the two or more prism pieces increases as the corresponding prism piece is positioned closer to any of the first end surface or the second end surface.

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.

A display or light blocking screen includes a liquid crystal (LC) array layer having a plurality of LC pixels, and a transparent LED layer having a plurality of LED pixels. A controller is operatively connected to the LC array layer and the transparent LED layer. The controller is configured to selectively trigger emission of light from a selection of the LED pixels, and to selectively darken a selection of the LC pixels that correspond directly to the selection of LED pixels. Therefore, the emitting LED pixels and the darkened LC pixels match and light is emitted from the LED pixels in substantially the opposite direction of the LC array layer. The display screen, or different aspects thereof, may be operatively incorporated into one or more windows of a vehicle, may be a standalone unit, or may be incorporated into a building.

A vehicle display apparatus has a display and a control unit. The control unit detects whether or not an error recognizable by users of the vehicle has occurred in an image on the display on the basis of the result of matching between a first error detection code, which is generated on the basis of image data transmitted to a display drive unit, and a second error detection code, which is generated on the basis of the image data received by the display drive unit, to determine whether notification is required or not, and provides notification on deterioration in the reliability of the image on the display by controlling light-emitting elements and sound output units provided on the vehicle display apparatus or by way of a superordinate device.
