A display apparatus providing a virtual image to user is provided. The display apparatus may include a hologram optical element on a path of light emitted from a display panel. The display panel may emit light having different peak wavelength ranges. The reflection angle or the refraction angle recorded in the hologram optical element is different according to the peak wavelength range. Thus, the display apparatus may provide a plurality of virtual images having different focal lengths to the user without physical movement or mechanical operation of the display panel.

A gauge assembly according to this disclosure includes a dial a dial face defining a scale indicative of an operating parameter, a conduit containing a first fluid and a second fluid that are immiscible during normal operating conditions. The conduit arranged about a periphery of the scale, wherein a visible demarcation between the first fluid and the second fluid is movable to correspond with the current operating parameter indicated on the scale.

An electronic controller of a vehicle is in electronic communication with lamp cover condition sensors, a headlamp switch, an off-road lamp switch and an electronic display. The electronic controller is configured to turn on the off-road lamp device in response to the off-road lamp switch being switched to the on condition and further in response to each of a plurality of predetermined conditions being met, the electronic controller further being configured to prevent the off-road lamp device from turning on in response to the off-road lamp switch being switched to the on condition and further in response to at least one of the plurality of predetermined conditions not being met, the predetermined conditions including at least a determination that the removable lamp cover of the off-road device has been removed, and a determination that the headlamp switch is in the second operating condition.

A display device is provided, such as for motor vehicles. The device comprises a display element that is backlit via a light source. A lightguide conducts light from the source. A pre-assembled back-lighting module serves to illuminate the display element, and facilitates manufacture and assembly of the device.

A vehicle head-up display includes a liquid crystal panel, a light source, a first polarizing panel, and a second polarizing panel. The liquid crystal panel has opposing input and output surfaces. The liquid crystal panel is configured to form an image oriented relative to a horizontal axis. The light source is configured to direct light toward the input surface, through the liquid crystal panel, and out of the output surface to project the image onto an interior surface of a vehicle windshield. The first polarizing panel is secured to the output surface and has a first polarization axis oriented at a first angle relative to the horizontal axis. The second polarizing panel is disposed between the first polarizing panel and the windshield. The second polarizing panel has a second polarization axis oriented oriented at a second angle relative to the horizontal axis.

A vehicle control apparatus comprises a shooting unit configured to shoot a periphery of a vehicle, a display unit configured to display an image shot by the shooting unit, an acquisition unit configured to acquire illuminance information regarding peripheral illuminance of the vehicle, and a control unit configured to control a display mode of the display unit based on the illuminance information acquired by the acquisition unit. The control unit changes the control of the display mode of the display unit between a case where peripheral illuminance of the vehicle increases and a case where the peripheral illuminance of the vehicle decreases.

A display device for a vehicle including: a first display configured to output first light forming first visual information; a second display configured to output second light forming second visual information; a light synthesizing unit located on an advancing path of each of the first light and the second light and forming a first acute angle with the first display and a second acute angle with the second display and configured to transmit therethrough the first light from the first display and reflect the second light from the second display; a first tiltable reflector; a second tiltable reflector; and a driving unit configured to: tilt the first tiltable reflector to form a first angle with the second display so the first tiltable reflector reflects part of the second light directed toward the light synthesizing unit toward a first direction, and tilt the second tiltable reflector to form a second angle with the first display so the second tiltable reflector reflects part of the first light directed toward the light synthesizing unit toward a second direction different from the first direction.

A vehicle lamp includes: a light source unit including one or more light sources and configured to generate light; a reflector configured to reflect at least part of the light generated by the light source unit; and a lens configured to transmit therethrough a first portion of the light that is generated by the light source unit and that is reflected by the reflector to the lens. The reflector includes: a reflective part configured to reflect, to the lens, the first portion of the light generated by the light source unit; and a non-reflective part configured not to reflect, to the lens, the light generated by the light source unit. The reflective part and the non-reflective part of the reflector are configured to selectively reflect the light generated by the light source unit towards the lens to output a light distribution pattern from the vehicle lamp.

A vehicle luminous signaling glazing forming, for example, a laminated vehicle windshield includes a first exterior glazing, with first main face and second main face, a lamination interlayer made of polymeric material with an other edge face, a second interior glazing, with third main face and fourth main face, the second main face and the third main face being the internal faces of the laminated glazing. The glazing also includes a flexible carrier for the diodes including a diode zone, an emerging electrical supply zone emerging from the other edge face, divided into a plurality of track strips, carrying electrical tracks, with an individual width Wi of less than 5 cm.

An optical display knob is mounted on an electronic display, such as a touch-screen display found in a vehicle interior cabin, and includes a knob body with an optical guide and a button located therein. The knob body is rotatable, whereas the optical guide is adhered to the electronic display via a transparent adhesive so that it is stationary, with respect to the electronic display. When the electronic display generates graphics or images, the corresponding light is transmitted through the transparent adhesive and the optical guide to a front display surface. At the front display surface, the graphics appear to be emanating from the front of the optical display knob, and not from the surface of the electronic display itself.
