An object of the present invention is to provide a head-up display apparatus further reduced in size, the head-up display apparatus having: an image display apparatus including a light source and a display element; and a virtual image optical system in which light emitted from the image display apparatus is reflected by a windshield or a combiner of the vehicle so that a virtual image is displayed in front of the vehicle, wherein the virtual image optical system has a concave mirror and a distortion correcting lens, and the distortion correcting lens is disposed between the image display apparatus and the concave mirror, the concave mirror is disposed in a housing including an outer case along a shape of an effective light path area of the image light from the image display apparatus, and the image display apparatus is attached to part of an outer periphery of the housing.

The invention relates to a head-up display device, a vehicle comprising such device and a method of forming an image in a head-up display device. The head-up display device is adapted to project an image on an image surface, such as a windshield. The device comprises a waveguide capable of guiding light carrying the image to be displayed, and an optical correction element. According to the invention, the waveguide is configured to couple light propagating therein towards the optical correction element, and the optical correction element is further configured to perform an optical function for said light and to direct the light towards the image surface through the waveguide.

A head-up display device is provided in a vehicle together with a headlamp. The head-up display device includes a light source, a control unit, and a projection unit. The light source emits white light whose correlated color temperature is changeable. The control unit adjusts the correlated color temperature of the white light emitted from the light source. The projection unit forms image light by the white light emitted from the light source. The projection unit projects the image light onto a projection target member disposed in front of a driver of the vehicle, thereby displaying a virtual image superimposed on a landscape for the driver. The control unit adjusts the correlated color temperature of the white light emitted from the light source in accordance with a correlated color temperature of irradiation light emitted from the headlamp.

A vehicle body motion informing device includes a vehicular interior part that configures an interior surface of a vehicular compartment of a vehicle, a lighting device mounted on a vehicular exterior side of the vehicular interior part and exiting light to a vehicular compartment, a control unit that receives an information signal relating to the motion of the vehicle body and controls the lighting device to exit light according to the information to inform the vehicle occupant of the motion of the vehicle body, and a surface member having semi-transmissivity and disposed to cover at least a lighting portion included in the vehicular interior part and a surrounding portion of the vehicular interior part. The lighting portion overlaps the lighting device and the light from the lighting device passes through the lighting portion to the vehicular compartment and the surrounding portion is near the lighting portion.

A vehicle display system is provided in a vehicle and includes: a first display device configured to project a light pattern onto a road surface outside the vehicle; a second display device inside the vehicle configured to display a predetermined image to an occupant of the vehicle such that the predetermined image is superimposed on a real space outside the vehicle; and a controller configured to control the first display device and the second display device. In a case where both the predetermined image and the light pattern are displayed, the controller causes a distance from the occupant to the predetermined image to match a distance from the occupant to the light pattern.

A display device includes a display panel and a lighting device. The lighting device includes a light source, a light guide panel including an emission surface from which a light of the light source is emitted toward the display panel, a first optical member including a prism array opposing the emission surface of the light guide panel, and a second optical member provided with a Fresnel lens on a surface opposing the emission surface of the first optical member, As viewed in a first direction orthogonal to a normal direction of the display panel, the Fresnel lens emit a light passing through a center of a transmissive region of the display panel in a direction inclined at a fifth angle with respect to the normal direction and bigger that a fourth angle between the display panel and the emission surface of the light guide panel.

A system for displaying information indicative of driving conditions, to a driver, using a smart ring are disclosed. An exemplary system includes a smart ring with a ring band having a plurality of surfaces including an inner surface, an outer surface, a first side surface, and a second side surface. The system further includes a processor, configured to obtain data from a communication module within the ring band, or from one or more sensors disposed within the ring band. The obtained data are representative of information indicative of one or more driving conditions to be displayed to the driver. The smart ring also includes a projector module display disposed on at least one of the plurality of surfaces, and configured to present information indicative of the one or more driving conditions.

A holographic display system for a motor vehicle includes a light source for generating a beam of coherent light and a spatial light modulator (SLM) having a two-dimensional pixel array. The two-dimensional pixel array modulates the beam of coherent light for generating a plurality of subframes, with each subframe being associated with one of a plurality of partial fields of view. The system further includes a scanner for directing the subframes onto associated sections of a display surface. The system further includes a computer having a memory including instructions, such that a processor is programmed to control the two-dimensional pixel array of the SLM for generating the subframes. The processor is further programmed to control the scanner for directing the subframes onto associated sections of the display surface and displaying a reconstructed image within a full field of view, which includes each of the partial fields of view.

A vehicle of the disclosure includes an apparatus for assisting driving of a host vehicle. The apparatus for assisting driving of the host vehicle includes a display configured to display vehicle driving information; an image obtainer configured to obtain an image of a road; a distance detector configured to detect surrounding objects; and a controller configured to calculate notification information based on the obtained image information of the road, the detected surrounding objects, and the vehicle driving information, and to display the calculated notification information to a driver in real time.

A display device of an autonomous vehicle is controlled based on data collected from sensors located in or on the vehicle. The display device is used to present one or more images to a driver and/or passengers of the autonomous vehicle. The display device can be, for example, a windshield and/or other window of the vehicle. Image data can be, for example, transformed to improve visual perception by passengers in the vehicle when the images are displayed on a curved shape of the windshield.
