The trim element includes a switching module extending between the cover layer and the lighting module, the switching module having at least two optical shutter areas extending opposite every backlit pattern area of the cover layer and being configurable between an open position and a closed position.

A three-dimensional display device includes a display panel, a controller, and a communication unit. The display panel is configured to display an image. An optical element is configured to define a propagation direction of image light emitted from the display panel. The communication unit is configured to receive a captured image of first eye and second eye different from the first eye, of a user. The controller causes the display panel to display a calibration image. The controller is configured so that, based on cornea images of different parts of the calibration image in the captured image that are viewed with the first eye and the second eye of the user, respectively, a parallax image is displayed on the display panel.

A charging device for an electric vehicle includes a network connection unit, a display light-panel, and a processor. The network connection unit is coupled to a server through a network and receives an indication of an operation of a charging procedure performed by a user device corresponding to the electric vehicle via the network. The display light-panel has an optical light-guiding component and a backlight module, wherein the optical light-guiding component has a fixed pattern printed thereon and the backlight module includes light sources, and the optical light-guiding component and the light sources are respectively disposed to operate the display light-panel in at least one illumination mode. The processor respectively changes the illumination mode of the display light-panel in response to the received indication, such that the display light-panel changes the light sources to generate an interaction display effect corresponding to the operation of the charging procedure.

A light control apparatus includes a diffuser plate, a light source, a light pipe, and a light blocker. The diffuser plate includes at least one opening therein. The diffuser plate includes feature located around the opening in the diffuser plate that exposes a portion of the diffuser plate. A light source positioned proximate a second surface of the diffuser plate is optically coupled to a light pipe positioned around a portion of the opening near the second surface of diffuser plate. A light blocker is positioned near a second portion of the at least one feature. The light blocker is positioned between the light source and the second portion of the feature, the light blocker having an opening therein to allow light to pass from the light source to the diffuser plate proximate the second portion of the feature.

A switchable backlight for a switchable privacy display apparatus comprises a collimated waveguide and an optical turning film comprising first and second arrays of elongate prismatic elements. High image luminance and image visibility is provided for off-axis viewers in a public mode of operation while in a privacy mode of operation visual security level above a perceived privacy threshold may be achieved for off-axis snoopers.

A light source device that supplies light in a specific polarization direction to an information display device includes a point-shaped or planar light source, an optical means for reducing the divergence angle of light from the light source, and a light guide having a reflection surface that reflects light from the light source to propagate to the information display device. The reflection surface of the light guide is arranged so as to face the information display device, and reflects specific polarized image light displayed on the information display device to be displayed on the window glass, which is an information display surface. Therefore, an information display system is realized in which the inside of the window glass can be visually recognized from the outside or the outside of the window glass can be visually recognized from the inside when image information is not displayed.

A vehicular head-up display (HUD) for displaying an image to a user of a vehicle having a windshield (15) includes an image projector (14) outputting a collimated image and an optical aperture expander. The optical aperture expander includes a light-guide optical element (LOE) (10) having two major external surfaces (30a, 30b). The image projector (14) injects the collimated image so as to propagate within the LOE by internal reflection at the major external surfaces. The LOE also has a set of parallel partially-reflecting internal surfaces (12) which progressively couple out the image illumination from the LOE. The optical aperture expander is deployed such that the image illumination coupled-out of the LOE (12) follows a light path including a reflection from a surface associated with the windshield (15) of the vehicle so as to be visible to the user while the user looks at a scene beyond the windshield.

The present disclosure relates to a function display for selectively displaying symbols representing switching states for a motor vehicle including a light guide stack of at least two transparent or translucent, planar light guides arranged in an overlaid manner in a stacking direction, which are spaced apart by a transparent or translucent layer including a material that is optically thinner compared to the adjacent light guides so that the light guides have a main surface facing towards an observer and a main surface facing away from the observer that faces towards a light guide which is most closely adjacent in stacking direction; at least one light source per light guide arranged to couple light into the respective light guide via an end face; wherein one light-refractive and/or light-scattering microstructured portion per light guide, which is provided in or on the light guide, is provided for generating a symbol display.

A mode of transportation, an infotainment system, and a device for operating an infotainment system of a mode of transportation having a finger strip extending in a linear or curved manner for haptically guiding a finger of a user, a detection unit for detecting swipe gestures carried out on the finger strip, an analyzing unit for processing detected swipe gestures, and a linear light outlet extending at least approximately completely along the finger strip.
