To provide a mirror unit and a head-up display device capable of suppressing deterioration in image quality while further increasing strength with a simple configuration. A mirror unit includes: a substantially rectangular plate-shaped main body plate portion formed of a synthetic resin; a reflection layer that is formed on one surface of the main body plate portion and reflects display light; two shaft portions provided at end portions on both sides in an X direction; and a rib that is erected on the other back surface of the main body plate portion and extends in a rib extending direction V. The rib is formed such that a width of the rib in a direction orthogonal to the rib extending direction V has a length equal to or more than 50% of a thickness of the main body plate portion.

A presentation control method for in-vehicle glass of a vehicle, includes obtaining a physical parameter associated with the vehicle; and determining content presented on the in-vehicle glass according to the physical parameter. Further, the present disclosure relates to a presentation control device for in-vehicle glass of a vehicle, wherein the presentation control device includes: a processor; and a memory for storing computer executable instructions that, when executed, cause the processor to execute the presentation control method according to the presentation control method.

A method of displaying information on a head-up display of a vehicle comprises determining a direction of gaze of a driver of the vehicle and selecting a display mode from a group of display modes based on the direction of gaze. Each display mode of the group of display modes defines information to be displayed on the head-up display. The group of display modes comprises at least a normal mode and an extended mode. Information displayed in the extended mode differs from information displayed in the normal mode. The method further comprises displaying the information on the head-up display according to the selected display mode.

An optical system includes a display including an active display region configured to emit an image. The active display region includes a predetermined region including a display center. A windshield of a vehicle includes an embedded reflective polarizer. The reflective polarizer reflects between about 20% to about 40% of incident light polarized along a first direction, and transmits at least 60% of the incident light polarized along a second direction. The reflective polarizer receives the image emitted by the active display region and reflects a portion toward the eye. For at least one first location within the predetermined region, the emitted image includes an image cone having an emitted central image ray emitted from the first location. The emitted central image ray is polarized along a third direction when incident on the windshield in an incident plane. The first and third directions are substantially parallel to the incident plane.

A window display system for a vehicle is provided to display blind spot information to an occupant. The system includes a vehicle window with an interior side facing the passenger compartment and an exterior side facing away, a transparent display integrated with the window to present visual information to the occupant, environment sensors mounted on the vehicle to acquire visual data of the exterior environment corresponding to a blind spot region, turn signal sensors operatively coupled to a turn signal to detect activation, and a controller operatively connected to the transparent display, environment sensors, and turn signal sensors. The controller includes a processor and memory storing instructions that, when executed, detect an object in the blind spot region and activation of the turn signal, and in response, cause the transparent display to overlay a highlighted representation of the object on the interior side of the window.
