A display device includes: a display that generates image display light; a concave mirror that reflects the image display light such that the image display light is projected onto a transparent member; and a drive mechanism that moves the display in a range in which a distance from the concave mirror to the display is smaller than or equal to a reference distance at which the image display light traveling from the concave mirror to the transparent member becomes parallel light.

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 picture generation unit comprises a light emitter array that is disposed on a substrate and provides a projection imaging light. The light emitter array includes a plurality of light emitting units. Each of the light emitting units includes a plurality of mini LED chips. An electronic control unit is electrically coupled to the substrate to control the mini LED chips to generate the projection imaging light. The light emitter array may emit light as well as present controllable images simultaneously. Because the picture generation unit abandons using the conventional backlight source and the module thereof, it can effectively utilize light energy and reduce radiation heat/waste heat. A vehicular head-up display system using the picture generation unit may improve operation reliability thereof.

An apparatus may include a first emitter and a second emitter. The first emitter may be configured to emit visible light comprising first heads up display information to be displayed to a driver of a vehicle. The second emitter may be configured to emit infrared light comprising second heads up display information to be displayed to one or more rear seat passengers of the vehicle.

An optical system includes a display system including a display having first and second display pixels interspersed with each other across the display. The first and second display pixels emit superimposed different respective first and second images polarized along the first direction. The display system includes a patterned retarder having pluralities of first and second retarder pixels aligned and registered with the respective first and second display pixels in one-to-one correspondence. The first retarder pixels are configured to receive and transmit the first emitted image as the first output image polarized along the first direction. The second retarder pixels are configured to receive, change the polarization direction, and transmit the second emitted image as the second output image polarized along the second direction. A reflective polarizer is configured to receive the first and second output images and substantially transmit the first output image and substantially reflect the second output image.

There is provided a small-sized HUD device having a high image display reliability and a high thermal reliability. A HUD device 1 includes: an image display unit 2 including a display panel (liquid crystal panel) 22 that displays an image, and an optical system 3 that projects image light of the displayed image onto a windshield of a vehicle, in which a virtual image of the image is visually recognized by light reflected off the windshield. In the image display unit 2, an effective display region 22a that displays the image is set to a region on a side close to one end of the display panel 22. The optical system 3 includes a first reflector 31 that reflects the image light emitted from the image display unit 2 and a second reflector 32 that reflects the reflected light of the first reflector 31 toward the windshield. The image display unit 2 is disposed to face the first reflector 31, and the display panel 22 is disposed in an attitude in which the one end faces the second reflector side 32.

The disclosure relates to the technical field of intelligent devices for vehicles, and particularly provides an augmented reality head-up display system for a vehicle, and a vehicle. The disclosure aims to solve the problem of an augmented reality head-up display system for a vehicle in the prior art usually having a large volume of a head-up controller host, poor heat dissipation of an image projection main optical head, a complex imaging light path, large space requirements for a dashboard, and poor imaging quality. To this end, in the disclosure, the vehicle includes a dashboard, and the augmented reality head-up display system includes an image projection main optical head, a head-up controller host, and a reflective imaging plate. The head-up controller host is arranged inside the dashboard, the image projection main optical head is arranged outside the dashboard, the dashboard is further provided with a light path capable of allowing for light to enter and exit the dashboard, imaging is achieved by means of the combined action of the image projection main optical head, the head-up controller host, the reflective imaging plate and the light path, and the imaging quality is improved.

The invention relates to a motor vehicle instrument cluster, comprising a digital display screen which is intended to be hidden from the vehicle passengers and capable of displaying a source image containing a multitude of indicator modules for the driver of the vehicle, and a panel (20) located below the digital display screen, at least the main central (20A) and upper (20B) portions of said panel being opaque and reflective, the panel (20) being inclined relative to the display screen so as to reflect the source image towards the driver so that the latter perceives, in his/her field of vision, a virtual image located in front of the panel (20), characterized in that the lateral (20C) and lower (20D) portions of the panel (20) are transparent.

An apparatus for a passenger compartment of a vehicle includes a display panel having an external portion and an internal portion. The passenger compartment is delimited by paneling to separate the passenger compartment from a region outside of the passenger compartment. The internal portion of the display panel is in the passenger compartment of the vehicle. The external portion of the display panel, separated from the passenger compartment by the paneling, is in the region outside of the passenger compartment of the vehicle. The external portion of the display panel is to generate an external display content inside of the region. The apparatus includes a strip in a first opening of the paneling. The strip is to project the external display content of the external portion of the display panel out of the region that is separated from the passenger compartment by the paneling and into the passenger compartment.

A display device includes: a display; an optical element including a first surface and a second surface; and a reflective member provided on the second surface. The first surface is a convex cylindrical surface whose axial direction is a first direction (parallel to the X axis), allows light emitted from the display to enter, and allows the light reflected by the reflective member to exit. The second surface is a convex cylindrical surface whose axial direction is a second direction (parallel to the Y axis) orthogonal to the first direction. The reflective member includes a reflective surface that reflects the light that has entered from the first surface toward the first surface. The reflective surface is a concave cylindrical surface whose axial direction is the second direction.
