A display-system includes a transparent-display-body having a first-surface and a second-surface opposite to the first-surface, a sensor to detect a brightness of the transparent-display-body or a brightness around the transparent-display-body, an arithmetic-unit configured to derive, based on the brightness detected by the sensor, a background luminance caused by outside-light as when the transparent-display-body is viewed from a side of the second-surface, and a controller to cause video to be displayed on the first-surface, wherein where rear-show-through-luminance that is a luminance of the video that occurs on the side of the second-surface is denoted as BB and the background luminance is denoted as SB, the controller controls a video luminance in accordance with the background luminance derived by the arithmetic-unit such that (BB/SB) is less than or equal to a predetermined-contrast-value, the video luminance being a luminance at which the video is to be displayed on the first-surface.

A pointer device for an indicator instrument, in particular for a vehicle, is provided with a light-guide body defined by a single piece, which, in use, receives light from a light source and has a hub and a pointer radially protruding from the hub; the hub has a surface covered by a shield and a light transmission portion, which, on the opposite side, ends with at least one light emission area; the device is provided with a cap defined by a single piece, which is separate from said light-guide body and has an intermediate portion and a lateral portion arranged in an inner and outer radial position, respectively, relative to the light transmission portion; the cap has at least one through opening aligned with the light emission area and connection portions extending radially and joining the intermediate portion to the lateral portion.

A component for a vehicle interior may comprise a light guide to allow light transmission from a light source for a user interface, and a cover to cover the light guide. The user interface may be presented at the cover. The cover may comprise a depression in an inner surface of the cover and the light guide may comprise a projection comprising a light-transmissive resin fit within the depression. The projection may comprise an icon to be presented at the user interface when illuminated, and to be hidden by the cover when not illuminated. The user interface may comprise a light display and an input device connected to a sensor. The icon may comprise an image. The cover thickness may be greater than the projection height. The component may comprise a steering wheel, console, floor console, center console, instrument panel, door panel, dashboard, display, armrest, or cockpit.

A main controller of an HUD is configured to: acquire road surface information of a front road surface based on a plurality of measurement points on the front road surface, which is detected by a road surface detection sensor mounted on a vehicle with the HUD and is positioned forward of a traveling direction of the vehicle; calculate, by using the road surface information, a virtual image plane position on a virtual image plane where a virtual image of a display object is displayed, which is a display position of the virtual image for displaying the virtual image along the front road surface; and calculate a display position of a display surface within an image display device, which corresponds to the virtual image plane position, so as to output, to the image display device, a control signal for displaying the display object on the display position of the display surface.

A trim element having an outer surface that is at least partially translucent, the outer surface defining a main display surface and a peripheral display surface, the peripheral display surface extending around at least a portion of the main display surface, a screen of a display device extending opposite the main display surface. The trim member includes an illumination device having a luminous sheet extending opposite the main display surface and the peripheral display surface so as to emit at least a first luminous signal onto the screen and at least a second luminous signal illuminating at least a portion of the peripheral display surface when the luminous sheet is activated.

This document describes a pedestrian alert system that can draw a driver's attention to a pedestrian on or near a roadway. The described pedestrian alert system can help prevent collisions with pedestrians and other objects in poor visibility environments or when drivers may be distracted. For example, a system can determine a presence of an object in or near a travel path of a host vehicle. The system can also determine the object's position relative to the host vehicle and control a light bar to provide an indication of the object. The indication can have specific characteristics to indicate the object's position relative to the host vehicle. In this way, the described pedestrian alert system can utilize sensors to focus a driver's attention on an object before a potential crash occurs and reduce the number of traffic-related deaths.

A three-dimensional (3D) projector includes a 3D display device and a camera. The 3D display device includes a backlight, a display including a display surface, a barrier, and a controller. The camera has an imaging direction that may be a direction of the image light emitted from the display or may be different from the direction of the image light. With the imaging direction of the camera being different from the direction of the image light, the controller performs a process to correct distortion on a captured image output from the camera with reference to the direction of the image light.
