A head-up display is mountable on a movable body, and includes a first display panel, a reflective optical element, and an optical member. The first display panel displays a first image. The reflective optical element at least partially reflects image light from the first image displayed by the first display panel toward a user of the movable body. The optical member is between the display panel and the reflective optical element and is light transmissive. The display panel includes a surface facing a surface of the optical member. Each of the surface of the display panel and the surface of the optical member includes a reflection reduction layer to reduce light reflection.

A head-up display system includes a first projection module that projects a first image to display the first image in a forward direction not directly facing a user, a second projection module that projects a second image to display the second image in a forward direction directly facing the user, and a reflective optical element that reflects at least a part of the first image and at least a part of the second image.

A hybrid projector apparatus for a vehicle includes a heads-up display (HUD) projector disposed in a housing that includes a transparent area. The hybrid projector apparatus includes a holographic optical elements (HOE) projector supported by and at least partly exterior to the housing and is arranged to project light through the transparent area.

A head-up display system includes a first projection module, a second projection module, and a first reflective optical element. The first projection module projects a first image. The second projection module projects a second image. The first reflective optical element reflects at least a part of the first image and at least a part of the second image. The first projection module includes a first display panel that displays the first image and projects the first image toward the first reflective optical element. The second projection module includes a second display panel that displays the second image, and an optical system that directs the second image toward the first reflective optical element.

A vehicle display device, includes: a curve information acquisition section configured to acquire information relating to a degree of curvature of a travel lane; a deceleration determination section configured to determine whether or not deceleration of a vehicle is required based on the degree of curvature of the travel lane and a vehicle speed; and a marking display section configured to, in a case in which deceleration is required, cause a display device to display a predetermined first marking superimposed along the travel lane at a display region inside a vehicle cabin.

The invention relates to a user interface for a vehicle adapted to present visible information; the user interface comprises a two-dimensional display for displaying information on a display portion, and an optical faceplate comprising a contact surface, a three-dimensional display surface for displaying information, and an optic light guide material provided between the contact surface and the three-dimensional display surface; wherein the two-dimensional display comprises a pixel arrangement and a cover layer covering the pixel arrangement; wherein the contact surface contacts the display to transmit information from the pixel arrangement to the three-dimensional display surface; wherein the faceplate is integrated into the display. The invention also relates to a vehicle.

An electronic device attachable to a vehicle, according to various embodiments of the present invention, comprises: a communication interface; a memory for storing instructions; and at least one processor connected to the communication interface and the memory, wherein the at least one processor can be configured so as to execute the stored instructions in order to: acquire, from another device embedded in the vehicle, information on a plurality of objects located within a designated distance from the vehicle; identify, among the plurality of objects, a designated object located within a designated distance from the vehicle; generate configuration information of at least one piece of content to be displayed through a head-up display (HUD), on the basis of a state of the designated object; and display, through the HUD, content for guiding the operation of the vehicle, on the basis of the generated configuration information.

An information display apparatus and an information display method configured to display video information of a virtual image on a windshield of conveyance is provided. The information display apparatus includes: a display configured to display the video information; and a virtual image optical system configured to display a virtual image at a front of the conveyance by reflecting light emitted from the display by means of the windshield. The virtual image optical system includes a concave mirror and an optical element. A reflective film is formed on a reflecting surface of the concave mirror. A protective film for preventing moisture absorption is formed on a facing surface. By forming end surfaces of the two surfaces as a curved surface or an inclined surface and forming them on the end surfaces to block moisture, moisture absorption of plastic is prevented.

A head-up display device includes: a display unit that produces a display light for the left eye by modulating a first illumination light derived from superimposing first illumination light beams output from a first region of a fly eye lens and produces a display light for the right eye by modulating a second illumination light derived from superimposing second illumination light beams output a second region of the fly eye lens; and an image processing unit that produces an image for the left eye and produces an image for the right eye; and a display control unit that causes a display unit to display the image for the left eye when the first illumination light is produced and causes the display unit to display the image for the right eye when the second illumination light is produced.
