To adjust the size or brightness of augmented reality information provided through an electronic device, the present disclosure provides an electronic device comprising an optical driving assembly including an image source panel for emitting image light, an optical element wherein the emitted image light is incident and totally reflected, a plurality of pin mirrors distributed in a region of the optical element and for deepening a depth of the image light reached, and a variable lens member provided at one point of an optical path before reaching the plurality of pin mirrors to vary a region where the image light reaches among the region where the plurality of pin mirrors are provided.

A display system for a vehicle includes a display unit mounted to the vehicle and is selectively operable in a first mode as a holographic display and in a second mode as a mirror. Holographic images may include rear view images obtained from a camera or computer generated graphics. Holographic images are displayed at a virtual image plane behind the display to reduce the operator's eyes accommodation.

An optical system includes a picture generation unit (PGU), a correcting optical unit configured to create, in a direction of a horizontal field of view (HFoV), a monotonic variation of an optical path length of light rays propagating from the PGU, and a combiner configured to redirect light rays propagating from the correcting optical unit toward an eye box, producing one or more virtual images observable from the eye box. The optical system provides a virtual image surface inclined in the direction of the HFoV for displaying the virtual images. The virtual image surface has a non-zero angle between projections on a horizontal plane defined by a first axis perpendicular to the virtual image surface and extending through an arbitrary intersection point on the virtual image surface, and a second axis parallel to a line of sight and extending from the eye box through the intersection point.

Disclosed embodiments are related to an optical system of an augmented reality (AR) head-up display (HUD) devices. The implementation of disclosed optical system in AR HUD devices improves visual ergonomics by providing enhanced stereoscopic depth of field (SDoF). The SDoF is created by the formation of a proper shape and spatial orientation of a virtual image surface (VIS) where a convex side is oriented towards a user or observer. When such optical systems of AR HUD devices are implemented in a vehicle, the improved visual ergonomics provides improved driving comfort and safety.

Methods, apparatus, devices, and systems for three-dimensional (3D) displaying objects are provided. In one aspect, a method includes obtaining data including respective primitive data for primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each element of a display for each of the primitives by calculating an EM field propagation from the primitive to the element, generating a sum of the EM field contributions from the primitives for each of the elements, transmitting to each of the elements a respective control signal for modulating at least one property of the element based on the sum of the EM field contributions, and transmitting a timing control signal to an illuminator to activate the illuminator to illuminate light on the display, such that the light is caused by the modulated elements of the display to form a volumetric light field corresponding to the object.

A vehicular display device includes a reflection-type hologram disposed inside a windshield of a vehicle and a projection device that projects display light toward the hologram. The hologram outputs the display light from the projection device as diffracted light that travels toward the eye range of the vehicle. The projection device is arranged such that display light reflected off the windshield travels in a direction different, from the direction toward the eye range in a vehicle width direction.

A cab having a human-machine interface to generate a holographic image in order to control comfort equipment installed in the cab. The human-machine interface includes: a camera capable of capturing images representing a gaze of an occupant, one image generation unit having (a) a computer capable of calculating the position of the location of the occupant's gaze from the captured images, the computer being adapted to generate the digital holographic image according to the position of the occupant's gaze, (b) a spatial light modulator receiving the generated digital holographic image, and (c) a light source illuminating the spatial light modulator. The human-machine interface also includes a reflector reflecting the light beams emitted by the spatial light modulator into a visualizing window to form a holographic image positioned between the windscreen and the seat.

Virtual reality (VR) displays are computer displays that present images or video in a manner that simulates a real experience for the viewer. In many cases, VR displays are implemented as head-mounted displays (HMDs) which provide a display in the line of sight of the user. Because current HMDs are composed of a display panel and magnifying lens with a gap therebetween, proper functioning of the HMDs limits their design to a box-like form factor, thereby negatively impacting both comfort and aesthetics. The present disclosure provides a different configuration for a VR display which allows for improved comfort and aesthetics, including specifically at least one coherent light source, at least one pupil replicating waveguide coupled to the at least one coherent light source to receive light therefrom, and at least one spatial light modulator coupled to the at least one pupil replicating waveguide to modulate the light.

A light filed (LF) display system for displaying holographic performance content (e.g., a live performance) to viewers in a venue. The LF display system in the venue includes LF display modules tiled together to form an array of LF modules. The array of LF modules create a performance volume (e.g., a stage) for displaying the performance content in the venue. The array of LF modules displays the performance content to viewers in viewing volumes. The LF display system can be included in a LF presentation network. The LF presentation network allows holographic performance content to be recorded at one location and displayed (concurrently or non-concurrently) at another location. The LF presentation network includes a network system to manage the digital rights of the holographic performance content.

An approach for generating an illustrated digital map is disclosed. The approach comprises receiving map information specifying a plurality of points of interest. The approach further comprises retrieving characteristic information of the plurality of points of interest. The approach further comprises generating one or more icons representing the plurality of points of interest based on the characteristic information, wherein the one or more icons are illustrated images. The approach also comprises creating an illustrated digital map including the illustrated images, wherein the illustrated digital map is scaled to highlight the one or more icons and to factor in display size of a device. The approach further comprises presenting the illustrated digital map via a graphical user interface.
