An apparatus for displaying a three-dimensional image. The apparatus includes a light source, an intensity modulator to modulate an intensity of a given light beam, a mirror device to modulate spatially the intensity-modulated light beam at a given time instant, a first optics to collimate the spatially-modulated light beam and an image waveguide comprising an in-coupling structure to receive the collimated light beam and an out-coupling structure comprising out-coupling sites. The image waveguide directs the collimated light to the out-coupling structure which selectively redirects multiple reflections towards a segmented optical structure comprising at least two types of segments to redirect a first part of the multiple reflections to form a first type image point P1 at a first focal distance d1, d1′ and a second part of the multiple reflections to form a second type image point P2 at a second focal distance d2, d2′.

The liquid crystal display panel sequentially includes: a first polarizing plate; a first substrate; a first alignment film; a liquid crystal layer containing liquid crystal molecules; a second alignment film; a second substrate; and a second polarizing plate. The liquid crystal display panel is a normally black liquid crystal display panel capable of shifting into a transparent display state. The first alignment film and the second alignment film have been subjected to alignment treatment such that a first domain and a second domain in which alignment vectors are different from each other are arranged side by side in a column direction. In a plan view, a liquid crystal alignment axis of the first domain and a liquid crystal alignment axis of the second domain obliquely intersect a polarization axis of the first polarizing plate and a polarization axis of the second polarizing plate and are parallel to each other.

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an image capturing device to capture one or more images, the one or more images corresponding to a field of the view of a user of a head-mounted augmented reality device, and a processor communicatively coupled to the image capturing device to extract a set of map points from the set of images, to identify a set of sparse points and a set of dense points from the extracted set of map points, and to perform a normalization on the set of map points.

A head-up display is described. A spatial light modulator is arranged to display a diffractive pattern of first picture content and/or second picture content. A screen assembly has first and second diffusers arranged in a stepped configuration so that the first diffuser is spatially offset from the second diffuser by a perpendicular distance. A light source is arranged to illuminate the diffractive pattern such that the first picture content is formed on the first diffuser and/or the second picture content is formed on the second diffuser. An optical system comprising at least one optical element having optical power is arranged so that the first and second diffusers have different object distances to the optical system.

Systems and methods for generating multi-layer hologram projections are described. For example, a system generally comprises at least two projection layers in a spaced-apart arrangement; at least one layer-specific projector device associated with each of the at least two projection layers, each layer-specific projector device being configured to project one or more images on an associated projection layer; and a processor coupled to each of the at least one layer-specific projector device, the processor being configured to control each layer-specific projector device to project one or more images on the corresponding projection layer.
