Provided is a structural body including a transparent plate and an interior member, the structural body being prevented from causing the reflection of the interior member on the transparent plate. The refection-preventing structural body of the present invention includes a transparent plate and an interior member. The transparent plate is arranged at the position at which reflected light on the interior member arrives, and the interior member is configured to reflect a larger quantity of P-polarized light than that of S-polarized light toward the transparent plate. In one embodiment, the reflection-preventing structural body is a vehicle interior structure.

Disclosed herein are structures and methods for assembling said structures to provide a glass-based and flush implementation of a display structure for a vehicle-based context. Employing the aspects disclosed herein, an implementer is provided a structure capable of passing head-impact tests, while prevent stray shard creation and providing an aesthetically superior design to convention implementation.

A windscreen display system for a motor vehicle has a head-up display device. The head-up display device has a projection device for emitting a projection light beam with a first item of image information towards a display region of a windscreen so that the information is reflected there and can be perceived in an eye region, and a transparent covering for protecting the projection device, the covering having a cover pane and an antireflection layer applied to one or both sides.

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.

In a head-up display, a cover member includes a first transmissive member and a second transmissive member that transmit a light beam including an image generated by an image generation unit. The first transmissive member is formed to face upward from a front end to a rear end. Likewise, the second transmissive member is formed to face upward from a front end to a rear end. The rear end of the first transmissive member is offset to an upper side from the front end of the second transmissive member.

A vehicular head-up display system provides a driver with two virtual images in different image distances, wherein each of the virtual images utilizes all pixels of a single image source. Linearly polarized light beams, which are emanated from the image source, pass through a dynamic polarization converter, whereby to form two image light beams with orthogonal polarization states that are switched fast for time-multiplexing. The two image light beams are selected by a polarization selection component for transmission and reflection respectively. The reflected image light beam is handled by an optical relay component to form an intermediate image. A curved mirror reflects the two image light beams to a virtual image reflecting surface to form two virtual images in different virtual image distances in respect to eyes of a driver in front of the virtual image reflecting surface.

A resin molded product that is applied to a vehicle display device has a surface on which a plurality of fine irregularities having surface roughness of equal to or larger than 1.0 μm and equal to or smaller than 10.0 μm and an array pitch of equal to or larger than 3.0 μm and equal to or smaller than 18.0 μm are molded. In other words, the resin molded product has the surface on which the fine irregularities causing a gloss value at an incident angle of 85° to be equal to or lower than 2 are molded. This configuration provides an effect that the resin molded product and the vehicle display device can lower gloss of the surface.

The present invention relates to the technical field of head-up display, and particularly relates to a head-up display system for an automobile. The head-up display system comprises a projection light source and laminated glass, and further comprises a transparent nanofilm; said film comprises at least two dielectric layers and at least one metallic layer; the projection light source is used for generating p-polarized light; the p-polarized light is incident on a surface of an internal glass panel distal to an intermediate film, said light having an angle of incidence of 42 to 72 degrees, such that the transparent nanofilm can reflect part of the incident p-polarized light.

A refractive optical system is disposed in an optical path from a display surface to a viewing area and between a projection optical system and the viewing area. A housing receives a display device, the projection optical system, and the refractive optical system, and is provided with an opening. An opening cover has at least partially a curved portion, and is disposed in the opening so that light emitted from the display surface is incident on a convex side of the curved portion. When a light beam that is emitted from a center of the display surface and reaches a center of the viewing area is referred to as a reference light beam, a head-up display satisfies the following condition (1):

L2≦L1  (1)

where

L1 is a distance from an end on the anterior side of the observer of the refractive optical system to the opening cover, and

L2 is a distance from a position at which the reference light beam passes through the refractive optical system to the opening cover.

An image display apparatus mounted in a head up display apparatus includes: an image display element that outputs display light; a diffusing member that receives the display light at a light receiving surface and outputs the display light as diffused light from a light output surface; and a light deflecting means that deflects the display light output from the image display element, provided between the image display element and the diffusing member. An image display surface of the image display element and the light output surface of the diffusing member are parallel, and the image display element, the diffusing member, and the light deflecting means are arranged in a state such that a line normal to the light output surface of the diffusing member is inclined with respect to the optical axis of the display light after being deflected by the light deflecting means.
