A method or system can be used with an aircraft or other vehicle. The system can include or the method can use a waveguide disposed above and below a top surface of a glare shield. The waveguide can be part of a head up display (HUD). The waveguide can be disposed to cover at least part of the head down display to provide an integrated display.

A HUD for a helmet having an image projector attached to a body and configured to project images. The HUD has a projection optical combiner configured to produce a transparent display of the images. A holder supports the combiner outside the helmet such that the images are visible to a user of the helmet when the head-up display is in use. A forward facing part of the combiner, such as the entire combiner or its forward facing portion, is user replaceable. A system that has the HUD and a spare user replaceable forward facing part and a system having the HUD and the helmet are additionally disclosed.

The present technology enables a user wearing a head-mounted display having a display section provided in front of the eyes of the user to directly check a state in front of the user. A head-mounted display includes: a display section; a casing supporting the display section in front of eyes of a user; and an optical system supported by the casing, the optical system allowing the user to view an image of an object disposed in a rear of the display section as viewed from the user.

The disclosures relates to a display system for a vehicle that includes a screen with two unique and opposite curved portions, integrally provided with each other, and a projection surface. A surface of the screen is bent in such a manner that at least one curved surface and a second curved surface are formed. The first curved surface on which information can be displayed is arranged aligned in the direction of an observer. The second curved surface is constructed in such a manner that information to be displayed on the second curved surface so that it can be projected in the direction of the at least one projection surface. The projection surface is at a distance from the second curved surface and is arranged so that it can be seen behind the screen (2) by the observer in the direction of the view of the observer.

A display device includes a display device main body, a first display surface, and a second display surface, and the display device main body includes a first emitting portion, a second emitting portion, and a housing accommodating them. The first emitting portion emits first display light. The first display surface is provided on a transmission member transmitting light and reflects, to a viewing position side, the first display light being emitted from the first emitting portion. The second emitting portion emits second display light that is different from the first display light. The second display surface is provided on a non-transmission member shielding light and forming at least a part of a light path of the first display light to the first display surface from the first emitting portion and reflects, to the viewing position side, the second display light being emitted from the second emitting portion.

Head-up display, which is mounted on a vehicle, performs projection on a transparent reflective member, and allows an observer to visually recognize a virtual image, includes display device that displays an image, and a projection optical system that has refractive optical system and projects displayed image displayed by display device on eye box of the observer. As an angle formed between a vector of a light beam that is incident on refractive optical system and a vector of an output light beam, the angle is greater at a light beam on an image end passing through a vehicle inner side of refractive optical system than at a light beam on an image end passing through a vehicle outer side of refractive optical system.

A display device for a vehicle includes: a first display unit that displays a real image of first information in a first display portion; and a second display unit that displays a virtual image of second information in a second display portion by projecting an optical image to the second display portion, the second display portion being disposed above the first display portion and transmitting an external image. The display device includes: a light emission unit located adjacent to a side of the first display portion to form a light emission area; and a control unit that changes the light emission area in a guiding direction from the first display portion toward the second display portion during a linking period for linking a particular virtual image display of the second information with a real image display of the first information.

A display apparatus includes: a housing including a top plate having an opening and two opposed side plate units; a display member capable of moving through the opening; a shutter configured to open and close the opening; and a moving mechanism provided on at least one of the two side plate units, the moving mechanism including a first slide member and a second slide member each moving along the at least one side plate unit and a transmission member transmitting an amount of movement of the first slide member to the second slide member while increasing the amount of movement, wherein the shutter moves according to movement of the second slide member.

Disclosed herein is an HUD integrated cluster system for a vehicle camera. The HUD integrated cluster system displays captured images of the rear view of the vehicle on a cluster and an HUD in front of the driver's seat. Thereby, the gaze shift distance and time may be reduced in watching the environment behind the vehicle and a traffic accident resulting from distraction from the front view may be prevented. The HUD integrated cluster system also displays, on the cluster and the HUD in front of the driver's seat, an image of at least one of the views of the rear center, rear left side and rear right side of the vehicle according to the speed of the vehicle, gear shift, blinking of a turn signal, and a steering direction of the steering wheel. Thereby, the driver may easily observe the rear view according to respective situations. In addition, the HUD integrated cluster system displays a captured image of a rear view of the vehicle and a warning light according to an object which is positioned near or is approaching the vehicle. Thereby, the driver's attention may be readily drawn when the vehicle moves backward or changes lanes.

Examples of the disclosure relate to optical apparatus, modules, and devices. The apparatus includes; at least one light guide including at least; a diffractive in-coupler configured to in-couple one or more input beams of light into the light guide from a light engine, an expander configured to expand the one or more input beams of light, and a diffractive out-coupler configured to out-couple the one or more expanded beams of light from the light guide. The at least one light guide is configured to provide a first virtual image in a first location to provide images for a head-up display and is configured to provide a second virtual image in a second location to provide images for a control panel.
