A light blocking screen includes a liquid crystal array mounted to a window. The liquid crystal array has a plurality of liquid crystal (LC) pixels, each of which is selectively darkenable. A controller is operatively connected to the liquid crystal array and configured to darken a set of the LC pixels, such that the darkened set of LC pixels limits light passage through the window in one or more selected areas. The LC pixels need not limit light passage through the entire window. The controller may determine a location of a glare source relative to the window and a location of a user proximate the window, and then darken the set of the LC pixels in an area between the glare source and the user, such that the glare source is limited from shining onto the user. The screen may be incorporated into vehicles or buildings.

The problem addressed by the present invention is to provide a head up display device capable of counteracting sunlight without using a shutter or a reflection type polarizing film. A first concave mirror has a curvature to cause the reflected display light to intersect vertically before reaching a second mirror, and a second concave mirror serves to reflect the received display light. A case is provided with a first shield and a second shield extending near an intersecting point to sandwich a light path between the first and second concave mirrors. The first and second shields can block external light entering into the case from outside the case and proceeding toward the first concave mirror after being reflected from the second concave mirror.

A vehicle lighting control system for controlling headlights of a vehicle and a display device comprises an illuminance detector for detecting an illuminance outside of the vehicle, and a lighting controller for controlling luminances of the headlights and the display device based on the detected illuminance. The lighting controller includes a headlight controlling module for turning the headlights off when the illuminance is above a first threshold, and turning the headlights on when the illuminance is the first threshold or below, and a display device controlling module for controlling the luminance of the display device to a first set value when the illuminance is above a second threshold, and controlling the luminance of the display device to a second set value when the illuminance is the second threshold or below, the second threshold being lower than the first threshold, the second set value being lower than the first set value.

A computer-implemented method includes receiving, with a vehicle computing system, global position system (GPS) data associated with a vehicle, determining a solar position relative to the vehicle, receiving trip information associated with the vehicle, and executing one or more vehicle actuators based at least in part on the GPS data, the trip information and the solar position relative to the vehicle. Determining the solar position can include determining a sun glare period during a future time period based at least in part on the trip information associated with the vehicle. The vehicle computing system may display a warning indicative of the sun glare period, generate a window tint command that causes the window to tint and/or generate a vent control command that causes the vent to change one or more of an airflow temperature, and an airflow velocity.

A display control device for a vehicle includes: a display controller that displays a determined display image including a display of a traveling state of the vehicle on a windshield of the vehicle; a visibility reducing area detector that detects a presence or an absence of a visibility reducing area on the windshield, the visibility reducing area reduces visibility of a driver; and a gaze detector that detects a gaze of the driver. When the visibility reducing area is detected, but the display of the traveling state does not overlap with the visibility reducing area, and the driver keeps the gaze on the visibility reducing area, the display controller displays, on the visibility reducing area, a traveling direction information necessary for driving the vehicle.

There is provided a head-up display for a vehicle. The head-up display has a first housing and a second housing. The first housing comprises a picture generating unit and optical system. The second housing comprises a substantially flat cover glass and a layer. The picture generating unit is arranged to output pictures. The picture generating unit comprises a light source and a spatial light modulator. The light source is arranged to emit light. The spatial light modulator is arranged to receive the light from the light source and spatially-modulate the light in accordance with computer-generated light-modulation patterns displayed on the spatial light modulator to form a holographic reconstruction corresponding to each picture. The optical system is arranged to receive the pictures output by the picture generating unit and relay the pictures using an optical combiner to form a virtual image of each picture. The optical combiner combines light output by the picture generating unit with light from a real-world scene to present combined images to a viewer within an eye-box. The second housing is disposed between the first housing and optical combiner. The substantially flat cover glass is arranged to protect the first housing. The layer is arranged to change the trajectory of light such that any sunlight reflected by the cover glass is deflected away from the eye-box.

A method for influencing light beams in the interior of a motor vehicle. The light beams come from the direction of a mirror bank associated with a head-up display. Different approaches are provided for providing an enhanced display option and simultaneously reducing a dazzling of a vehicle occupant by unwanted reflections. The light beams are generated in the mirror bank, wherein some of the generated light beams are blocked in the region of the mirror bank in such a way that a particular keep-clear region is created into which reflected light beams can no longer enter, or generated light beams in the region of the mirror bank are directed without reflection onto a particular viewing region, or the generated light beams in the region of the mirror bank are polarised and only such polarised portions of the light beams that cause no or only negligible reflections exit the mirror bank.

The vehicular display control device is mounted on an autonomous driving vehicle provided with a windshield display. The windshield display is configured to change a transmittance of external light. The vehicular display control device includes a transmittance control unit configured to reduce the transmittance in order to promote a sleep of at least one passenger.

A head-up display for a vehicle. The head-up display comprises a picture generating unit configured to project an image onto a glass surface and an optical stack. The optical stack comprises an infrared reflective waveplate and a dual brightness enhancement film. The infrared reflective waveplate transforms an incoming solar light beam from unpolarized light to incoming polarized light having an incoming S-polarization component and an incoming P-polarization component. The dual brightness enhancement film receives the incoming polarized light from the infrared reflective waveplate and eliminates substantially all of the incoming P-polarization component. The dual brightness enhancement film transmits substantially all of the incoming S-polarization component.

Embodiments of this disclosure pertain to a vehicle interior system comprising a base having a base surface; and a glass article coupled to the surface, wherein the glass article comprises a first portion comprising a first elastically deformed surface forming a first concave shape with a first radius of curvature from about 20 mm to about 2000 mm, and a second elastically deformed surface directly opposite the first elastically deformed surface that forms a second convex shape, wherein the second elastically deformed surface has a surface compressive stress that is less than a compressive stress at the first elastically deformed surface, and a second portion adjacent the first portion, wherein the second portion is substantially planar portion or curved.
