Examples of the disclosure relate to optical apparatus, modules, and devices. The optical apparatus includes a control panel and at least one light guide. The at least one light guide includes at least; a diffractive in-coupler configured to in-couple one or more input beams of light into the light guide from a first light engine, an expander configured to expand the one or more input beams of light, and an out-coupler configured to out-couple the one or more expanded beams of light from the light guide. The at least one light guide is transparent and is provided overlaying at least part of the control panel and is configured to display virtual images at a longer focal distance than the control panel.

Disclosed herein is an HUD integrated cluster system for a vehicle camera. The HUD integrated cluster system displays captured images of the rear view of the vehicle on a cluster and an HUD in front of the driver's seat. Thereby, the gaze shift distance and time may be reduced in watching the environment behind the vehicle and a traffic accident resulting from distraction from the front view may be prevented. The HUD integrated cluster system also displays, on the cluster and the HUD in front of the driver's seat, an image of at least one of the views of the rear center, rear left side and rear right side of the vehicle according to the speed of the vehicle, gear shift, blinking of a turn signal, and a steering direction of the steering wheel. Thereby, the driver may easily observe the rear view according to respective situations. In addition, the HUD integrated cluster system displays a captured image of a rear view of the vehicle and a warning light according to an object which is positioned near or is approaching the vehicle. Thereby, the driver's attention may be readily drawn when the vehicle moves backward or changes lanes.

A head-mounted display (HMD) system includes a head-mounted frame that encases a portable electronic device (PED) that includes a touch-less sensor, and the PED. The frame includes: a front slot to hold the PED and maintain contact with the PED's display face; an entry via dimensioned to prevent blockage of the sensor's field of view; and a light turning element positioned to redirect the sensor's field of view through an exit via in the frame and into open space outside of the frame. The PED includes: the sensor to detect a touch-less gesture; an image display to display image content on the PED's front display face; and processing circuitry configured to change modes from handheld mode to HMD operation mode based on a determination that the PED is encased by the frame and to select the image content based on input signals received from the sensor and the mode.

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 combined head up display and instrument cluster arrangement for a motor vehicle includes a substantially planar liquid crystal display having a first side and a second side opposite the first side. A first area of the liquid crystal display is viewable as an instrument cluster display by a human viewer who is disposed closer to the first side than to the second side. A backlight is disposed closer to the first side than to the second side. The backlight is aligned with a second area of the liquid crystal display such that a light field is emitted by the backlight through the second area. Head up display optics are positioned to receive the light field.

Head-up display, which is mounted on a vehicle, performs projection on a transparent reflective member, and allows an observer to visually recognize a virtual image, includes display device that displays an image, and a projection optical system that has refractive optical system and projects displayed image displayed by display device on eye box of the observer. As an angle formed between a vector of a light beam that is incident on refractive optical system and a vector of an output light beam, the angle is greater at a light beam on an image end passing through a vehicle inner side of refractive optical system than at a light beam on an image end passing through a vehicle outer side of refractive optical system.

A vehicular display apparatus includes a light source unit that emits laser light; a first optical system that uses a first projection surface, onto which a display image is projected, to make a virtual image discernible; a second optical system that uses a second projection surface, onto which the display image is projected, to make a real image discernible; a controller; and a switching mechanism that switch the two optical systems. The distance between the light source unit and first projection surface is smaller than the distance between the light source unit and second projection surface.

A projector includes a plurality of light-sources that outputs a laser light, a detector that detects a light amount of the laser light, and a controller that controls an output of the light-sources based on a characteristic indicating a relationship between a forward current value and a light output when a current value of the light-sources is smaller than a predetermined current value. When the current value of the light-sources is greater than or equal to the predetermined current value, the controller controls the output of the light-sources based on the detected light amount. The predetermined current value is a current value that can be laser-oscillated.

A method controls a transmission in a motor vehicle. The method involves displaying transmission information on a primary display, determining when a hand is approaching a gear selector, and initiating a display of, and then displaying, gear selection information on a secondary display when the hand is approaching the gear selector, before the hand touches the gear selector, the secondary display being a multi-use changeable display that, at different times, displays information for different systems of the motor vehicle. The method may therefore provide the information to the driver when it is needed, before the gear is shifted.

A display unit is equipped with an LED circuit body for irradiating light onto the windshield of a vehicle and a surface panel positioned on the front side in the light irradiating direction of the LED circuit body and constituting part of the surface of the instrument panel of the vehicle. The surface panel is provided with a plurality of pores formed in the direction connecting the LED circuit body to the windshield. The light irradiating direction of the LED circuit body is set to the direction in which the light irradiated from the LED circuit body and reflected by the windshield is visually recognized by the driver.
