Disclosed is a display device for displaying a virtual image so as to be visually perceived by an occupant of a moving body through a transparent member. The display device includes an image generator configured to generate an image to be displayed as a virtual image; an orientation information acquisition unit configured to acquire information on an orientation of the moving body; and a display change processor configured to change the display of the virtual image in accordance with the information on the orientation acquired by the orientation information acquisition unit.

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 vehicle display device includes a display that emits a display image projected on a windshield provided outside as display light, two reflective mirrors that are disposed on a light path of the display light from the display to the windshield and reflect the display light, an optical sensor that detects the external light entering from an opening communicating between the outside and an internal space, and a controller configured to execute temperature decreasing operation of the display for decreasing a temperature thereof when the optical sensor detects the external light. The optical sensor is disposed at a position to which external light directed toward the display via the reflective mirror is reflected by the display to be directed.

A vehicle includes a controller programmed to, responsive to detecting a barcode displayed outside the vehicle via an exterior sensor, decode the barcode, and project an image representing an information decoded from the barcode on a windshield of the vehicle, the image overlaying the barcode from a perspective of a user.

A display system of one aspect according to the present disclosure includes: a display unit; a first optical member; and a second optical member. The display unit includes a display surface for displaying an image. The first optical member includes a first reflective surface for reflecting rays of light constituting the image. The second optical member includes a second reflective surface for reflecting rays of light reflected from the first reflective surface to form a virtual image in a target space. An angle of view in a length direction of an available area for display of the virtual image with regard to a point of view position for the virtual image is denoted by [deg]. A length of the display surface is denoted by W [mm]. W is equal to or greater than a prescribed value given by 12.026.6. is equal to or greater than 8.0.

The combiner has a reflecting surface that reflects incident light. When the incident light has an incident angle in a range from 0 to 25, inclusive, defined as a first value, in a wavelength range from 400 nm to 700 nm, inclusive, the upper limit wavelength of a wavelength range having a reflectance of 90% or more of the reflectance peak of the incident light is shorter than 700 nm. When the incident angle takes a second value in a range from 60 to 85, inclusive, in the wavelength range from 400 nm to 700 nm, inclusive, the reflectance peak of an S-wave component contained in the incident light has a wavelength shorter than 570 nm.

A vehicular display apparatus includes a display device, a magnifying mirror, and a turning back mirror. The display device emits display light corresponding to a display image to be visually recognized by a driver on a vehicle. The magnifying mirror reflects the display light to project the display image on a windshield of the vehicle. The turning back mirror is disposed on an optical path between the display device and the magnifying mirror and has a concave reflecting surface that reflects the display light. The magnifying mirror has the magnifying power that is set higher than that of the turning back mirror.

A vehicle system includes a warning device and at least one electronic control unit. The at least one electronic control unit is configured to present a light stimulus to a driver, and determine whether the driver is facing forward, determine whether the driver holds a steering wheel, and cause the warning device to perform a first warning when it is determined that the driver is not facing forward while the light stimulus is being presented. The first warning is either the vibration or the sound. The at least one electronic control unit is configured to perform a second warning when it is determined that the driver does not hold the steering wheel before a predetermined time elapses after the first warning is started. The second warning includes the vibration and the sound.

Arrangements of the present disclosure disclose a head-up display, a head-up display method, and a vehicle. The head-up display includes a head-up display component configured to display an image on a projection location. The display includes a master control component connected to a driving component. The master control component is configured to obtain vehicle information, analyze the vehicle information, and generate a control instruction based on an analysis result. The vehicle information includes vehicle positioning information and vehicle attitude information, or traveling road information and vehicle attitude information. The driving component, connected to the head-up display component, is configured to adjust the head-up display component based on the control instruction such that the projection location of the image displayed by the head-up display component remains at a consistent relative height with respect to the ground.

There is provided a vehicle including (i) a vehicle main body, (ii) an input device that receives a destination input operation, (iii) a first display that displays information on a route to a destination inputted by the input device, the first display being arranged in the vehicle main body, (iv) an acquisition device for acquiring location-related information based on a current location of the vehicle main body or a location of a goal point of the vehicle main body, and (v) a second display that displays the location-related information acquired by the acquisition device, the second display being arranged in the vehicle main body.
