Provided are a projection assembly, a display system and a vehicle. The projection assembly is applied to the vehicle, and the projection assembly includes: a housing, a bottom cover, a display module, a heat dissipation assembly and an imaging lens. The housing is connected with the bottom cover, and the housing and the bottom cover form an accommodating space, the heat dissipation assembly, the display module and the imaging lens are all disposed in the accommodating space, and the display module is disposed on the heat dissipation assembly; and the imaging lens includes a lens barrel and a lens assembly, the lens barrel is disposed on the heat dissipation assembly, the lens assembly is disposed in the lens barrel, and the lens barrel surrounds the display module, the display module faces the lens assembly, the housing is provided with an opening, and the lens assembly faces the opening.

A projection unit for a field-of-view display device designed to superimpose, via reflection, a virtual image on a reflection pane, in particular a vehicle pane, arranged in the field of view of a user, includes at least one rectangular imaging display area arranged in or below a top side of an instrument panel of a vehicle and formed by a mechanically movable belt with at least one light source bar fastened thereon which extends across its direction of belt movement and carries strung-together light sources in its direction of extent. The light sources are contactlessly controllable synchronously with the belt movement and independently of one another for creating a desired display content in the display area. At least one receiver circuit board is fastened to the belt and electrically connected to the light sources. At least one associated transmitter circuit board is arranged stationarily in the projection unit in a manner mechanically decoupled from the belt and designed for contactless power and video signal transfer to the light sources via the at least one receiver circuit board.

Provided is a display device capable of adequately displaying in accordance with a condition. In a HUD device including a projector projecting an image that is to be a virtual image, a screen to which an image from the projector is projected, a magnifying optic magnifying the image projected on the screen, the screen is moved by an actuator in a direction parallel to an optical axis of the projector.

A dustproof cover having a reduced size in a depth direction is formed. In displaying a virtual image (53) visible to a driver by reflecting projection light projected in front of a driver on a windshield (light-transmitting member), a dustproof cover provided in a path of the projection light to close an opening (29) includes a recessed surface provided throughout a front and rear direction of a vehicle (10) and a cylindrical surface provided such that the recessed surface is continuous throughout a right and left direction of the vehicle (10). Curvatures of the recessed surface are configured to increase toward a front side of the vehicle (10), and therefore outer light entering the opening (29) from a position above the vehicle (10) is reflected in a direction invisible to the driver.

A head-up display device displays information to a driver in a form of a virtual image by projecting display light onto a reflection member. The head-up display device includes a display device which displays a virtual image of a first display image in a first display plane by emitting display light including the first display image and which displays virtual images of a plurality of second display images in a plurality of second display planes by emitting display light beams including the plurality of second display images, respectively. The first display plane is substantially perpendicular to a reference plane. The second display planes are substantially perpendicular to the reference plane and are arranged in a front-rear direction of the driver in a layered manner, and in which the virtual images of the plurality of second display images are displayed so as to be arranged along the reference plane.

There is provided an HUD main body for displaying front display information formed as front virtual image on a line of sight of a passenger, lower display information formed as lower virtual image below the front virtual image, and upper display information formed as upper virtual image above the front virtual image. The lower virtual image and the upper virtual image are formed to be closer to the passenger as they are farther away from the front virtual image, or toward the lower side and the upper side, respectively.

A vehicle display device includes: a housing mounted on a vehicle and having an opening facing a windshield; an image display device that is disposed inside the housing and outputs display light of an image; a mirror that is disposed inside the housing, faces the windshield through the opening, and reflects the display light toward the windshield; a cover that is transparent, disposed at the opening and having a free-form surface formed to have an optical function; and a suppression means that is disposed at an edge of the cover and suppresses reflection of light on an end surface of the cover.

This application provides an optical display and a transport means. The optical display includes a housing, a light source unit, a transmissive-reflective optical element, and a curved mirror. The housing is provided with a first opening. The light source unit is fastened to the housing and is configured to emit imaging light. The transmissive-reflective optical element is fastened to the housing, covers the first opening, and is configured to: transmit and reflect the imaging light. The curved mirror is fastened to the housing and is configured to reflect the imaging light. The imaging light emitted by the light source unit is reflected to the curved mirror through the transmissive-reflective optical element, and the curved mirror transmits the imaging light to the outside of the housing through the transmissive-reflective optical element.
