Provided are a projection-type display device, a safe-driving support method, and a non-transitory computer readable recording medium storing a safe-driving support program capable of securing safety while providing sufficient information to a driver even in a situation where a field of vision in a traveling direction of a motor vehicle is poor. An HUD includes a light modulation unit that modulates light emitted from a light source unit; a projection unit that projects the light modulated by the light modulation unit onto a combiner; a first image information generation unit that generates first image information and outputs the first image information to the light modulation unit; a second image information generation unit that generates second image information and outputs the second image information to a display device; and a control unit that controls operations of the first image information generation unit and the second image information generation unit.

A vehicular heads-up-display system includes a windshield-mountable partially reflective mirror that allows a vehicle user to view material displayed on the partially reflective mirror while, at the same time, viewing the road ahead without obstruction. A mount configured to accept a portable electronic device, such as a smartphone, may be situated to project the display of the portable electronic device to the windshield mountable partially reflective mirror when mounted in a vehicle. A tactile input device, including a wireless interface for entry of and transmission of input from a vehicle user to a smartphone may be configured for mounting on a vehicle steering wheel.

A vehicle-mounted apparatus includes a cluster display unit attached to an instrument panel and a HUD. The vehicle-mounted apparatus determines a running state of the vehicle and adjusts the focal length in the HUD such that the position of a virtual image of a projected image is near the cluster display unit or is a forward position on the windshield.

An image generation device having: a spatial light modulator; a source of light; a beam deflector; an illumination waveguide and an image transport waveguide, each waveguide containing at least one switchable grating; and a coupler for directing scanned light into a first set of TIR paths in said illumination waveguide. A switchable grating in the illumination waveguide diffracts light onto the SLM, a switchable grating in the image transport waveguide diffracting image-modulated from the SLM into a waveguide path.

A head-up display is mounted to a vehicle having a windshield, and includes a display element configured to display an image, a first optical system configured to reflect the image displayed by the display element and project the image onto the windshield; and a second optical system configured to reflect the image displayed by the display element and project the image onto the windshield. The image projected with the first optical system is projected onto the windshield at a position below a position of the image projected with the second optical system.

A display device for a vehicle includes: a first display unit that displays a real image of first information in a first display portion; and a second display unit that displays a virtual image of second information in a second display portion by projecting an optical image to the second display portion, the second display portion being disposed above the first display portion and transmitting an external image. The display device includes: a light emission unit located adjacent to a side of the first display portion to form a light emission area; and a control unit that changes the light emission area in a guiding direction from the first display portion toward the second display portion during a linking period for linking a particular virtual image display of the second information with a real image display of the first information.

A compact, lightweight, multi-wavelength display system which can be used for simultaneous viewing with both eyes is provided. The system utilizes a field flattener lens to remove abrasions introduced by the system's lenses. The system also uses a polarization selective optical element that reflects one linear polarization state while transmitting radiation of the orthogonal linear polarization state. The PS element is used in combination with a quarter wave plate and an optical element, the optical element including a partially reflective surface. The optical element may either be a single element or an optical doublet. In the latter configuration, the partially reflective surface is at the interface between the two singlets that comprise the doublet. The system also includes an image source that either alone, or in combination with other optical elements, produces circularly polarized light of the desired rotary sense.

A method for enhancing a field of view of a driver of a transportation vehicle with supplementary information, in which the supplementary information is depicted via a display unit display. Observation of the surroundings of the transportation vehicle takes place and, in response to the observation of the surroundings having detected a relevant object for which a potential significance arises, the relevant object is depicted on the display unit and the relation to the real object is emphasized in the field of view of the driver by the depicted object being visually highlighted in an environmentally synchronous state with respect to the real object. Also disclosed is an appropriately designed apparatus for use in an observer transportation vehicle, an appropriately designed apparatus for use in an object, and a transportation vehicle.

A head-up display apparatus is provided with an image emission mechanism that emits image display light, and a combiner arranged in front of an eye (or eyes) of a pilot to introduce the image display light to the eye(s) of the pilot. The head-up display apparatus is equipped with a light guide including first and second plane arranged in parallel planes, an incidence plane including a first reflector and an emission plane including a second reflector disposed between the first and second planes. The light guide is configured to reflect image display light from the emission mechanism to the combiner.

A wearable computing device having a main computing element having a center portion and at least two arms and a display element operably connected to arms to enclose a region within which a body part may be inserted. Each arm may include a docking element connectable to the display element and may be configured to slide within the arm to move the display element relative to the center portion of the main computing element. A pivot arm may pivotably connect the display element to the slider arm to permit pivoting of the display element relative to the plane of the main computing element.
