A vehicular accessory system includes an overhead console configured to mount at an interior portion of a vehicle, and an interior rearview mirror assembly having a mirror head mounted via mounting structure at the overhead console. The overhead console includes a base portion configured to attach at the interior portion of the vehicle to mount the overhead console at the interior portion and an extending portion that, with the overhead console mounted at the interior portion of the vehicle, extends from the base portion along and spaced from a headliner of the vehicle. The overhead console includes a light source that, with the overhead console mounted at the interior portion of the vehicle, and when electrically operated to emit light, light emitted by the light source illuminates a surface at the interior portion of the vehicle above the overhead console.

A display apparatus and a display system are provided, and relate to the field of display device technologies, to enhance visual experience generated when a picture is displayed by using an existing reflective display window such as a windshield and a bathroom mirror, so that a sense of presence and immersion is improved. The display apparatus includes an image generation unit and an optical imaging unit. The image generation unit is configured to generate a real image whose display surface is a curved surface. The optical imaging unit is configured to perform imaging on the real image, to generate an enlarged virtual image corresponding to the real image, where a display surface of the virtual image is a curved surface adaptive to the display surface of the real image.

This application provides example multi-focal-plane image generation apparatuses, example head-up display apparatuses, example methods, and example devices. One example apparatus includes a pattern generation device and a focal length adjuster. The pattern generation device is configured to generate a light beam that carries image information, and irradiate the light beam to a surface of the focal length adjuster. The focal length adjuster is configured to perform focal length adjustment on the light beam that is irradiated to the surface of the focal length adjuster to generate a plurality of focal planes of the multi-focal-plane image generation apparatus.

A display system is provided. The display system includes a windshield, a picture generation unit (PGU), and an optical element, where the windshield includes a first windshield surface and a second windshield surface. The PGU projects a light beam corresponding to a picture generated by the PGU to the optical element. The optical element directs the light beam to the first windshield surface. The first windshield surface refracts the light beam to the second windshield surface, and reflects the light beam to a human eye for receiving. The first windshield surface refracts a light beam reflected from the second windshield surface to the human eye for receiving. After reflection by the first windshield surface, the light beam forms a first virtual image with the picture. After reflection by the second windshield surface and refraction by the first windshield surface, the light beam forms a second virtual image with the picture.

A head-up display device includes: light sources; a light source driver that drives the light sources; a second control unit that illuminates the light sources via the light source driver on the basis of illumination control data; and a DMD display element that generates display light on the basis of illumination light emitted by the light sources. The illumination control data includes control modes for generating the illumination light brightness corresponding to a requested brightness. The control modes have differing brightness ranges, which partially overlap each other. The second control unit switches modes between the control modes when the requested brightness has reached a mode switching value, which is located in a non-end part of an overlapping region where one of the brightness ranges of one of the control modes and another one of the brightness ranges of another one of the control modes overlap.

A floating-information display includes a first quarter-wave retarder disposed on a side of an optical plate. A reflective polarizer is disposed between the first quarter-wave retarder and the optical plate. A first display is configured to transmit a first image along a first axis through the first quarter-wave retarder to the reflective polarizer. The reflective polarizer redirects the first image along a second axis through the first quarter-wave retarder toward a viewer. The first image appears to the viewer to be oriented normal to the second axis and at a first location. A second display is configured to transmit a second image to the optical plate. The second image is transferred through the first quarter-wave retarder along the second axis toward the viewer. The second image appears to the viewer to be oriented normal to the second axis and at a second location.

According to at least one aspect, the present disclosure provides a head-up display device comprising: a housing including a receiving space within; a picture generation unit (PGU) disposed within the housing, for projecting an image related to vehicle driving information; one or more reflection members for reflecting an image projected from the PGU; a fixing member formed to be fixed to a vehicle body; and one or more length adjustment members coupled to the fixing member, for movably supporting the housing.

A carbon decorative panel includes a clear decoration body and a carbon color layer. The clear decoration body has a main body 10a transmitting light and includes a carbon-toned irregular surface provided on the opposite side to the viewer side of the main body and having a carbon-toned pattern formed with protrusions and depressions. The carbon color layer is laminated on the carbon-toned irregular surface, includes a reflective surface reflecting incident light transmitted through the clear decoration body, and is colored in a carbon color.

A display system includes an optical element through which light diverges and an imaging optical system configured to form an image by projecting diverging light diverging through the optical element. In the display system, the image formed by the imaging optical system is visually recognized by a viewer, and a condition in an equation tan 0≥(T×B)/(S×O) is satisfied, where θ denotes a divergence angle of the optical element, T denotes distance between the image forming optical system and the formed image, B denotes a range of an eye box that is an area through which the formed image can visually be recognized, S denotes distance between the formed image and a viewpoint of the viewer of the formed image, and O denotes distance between the optical element and the image forming optical system. In the above equation, each distance indicates length of an optical path that passes through a center of an image formed by the light when an object is observed from a reference eyepoint.

A holographic head-up display (HUD) including: a picture generation unit (PGU) including at least one laser light source to generate an optical image to be projected on a HUD; a first mirror to reflect the optical image from the PGU; a second mirror to reflect the optical image reflected by the first mirror; and a holographic optical element (HOE) to diffract the optical image reflected by the second mirror at a first diffraction angle to provide an output optical image in a target direction. The first mirror includes a reflective compensatory HOE to diffract the optical image from the PGU at a second diffraction angle, and in response to change of a wavelength of the optical image from the PGU, the reflective compensatory HOE is configured to diffract the optical image from the PGU at a third diffraction angle different from the second diffraction angle such that the HOE provides the output optical image in the target direction.
