  • Publication number: 20170097507
    Abstract: A display subsystem for a virtual image generation system comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted as a fixed-free flexible cantilever. The drive assembly is configured for displacing a distal end of the optical fiber about a fulcrum in accordance with a scan pattern, such that the emitted light diverges from a longitudinal axis coincident with the fulcrum. The display subsystem further comprises an optical modulation apparatus configured for converging the light from the optical fiber towards the longitudinal axis, and an optical waveguide input apparatus configured for directing the light from the optical modulation apparatus down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to an end user.

  • Publication number: 20150346495
    Abstract: Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a spatial light modulator operatively coupled to an image source for projecting light associated with one or more frames of image data, and a variable focus element (VFE) for varying a focus of the projected light such that a first frame of image data is focused at a first depth plane, and a second frame of image data is focused at a second depth plane, and wherein a distance between the first depth plane and the second depth plane is fixed.

  • Patent number: 9121999
    Abstract: An optical film and a display device having the same are provided. The optical film has a light input face, a light output face opposite to the light input face, and a light-output structure disposed on the light output face. The light-output structure includes a plurality of light output microstructures such as prisms disposed side by side along a first direction on the light output face. Each prism has a first quadrilateral cross section parallel to the first direction. A first side of the quadrilateral cross section is connected to the light output face and includes a first angle with the light output face, wherein the first angles of the prisms continuously arranged have angle values varying in a periodic manner.

  • Publication number: 20150222884
    Abstract: Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a scanning device for scanning one or more frames of image data. The scanning device may be communicatively coupled to an image source to receive the image data. The system may further comprise a variable focus element (VFE) operatively coupled to the scanning device for focusing the one or more frames of image data on an intermediate image plane, wherein the intermediate image plane is aligned to one of a plurality of switchable screens. The plurality of switchable screens may spread light associated with the intermediate image plane to specific viewing distances. The system may also comprise viewing optics operatively coupled to the plurality of switchable screens to relay the one or more frames of image data.

  • Patent number: 8804067
    Abstract: A display device includes a display module, a light source module and a guiding optical film. The display module includes a first substrate, a second substrate and a display medium. The light source module generates directional light. The display module has a vertical electric field. The display medium is optically isotropic, and the display medium is optically anisotropic when driven by the vertical electric field. The directional light is not perpendicular to the first substrate when the directional light enters the display nodule. The directional light is not perpendicular to the second substrate when the directional light exits the display module. The guiding optical film is disposed on the second substrate and has a light incident surface and a light emitting surface. After the directional light exits the guiding optical film, emitting light is formed, and the emitting light and the light emitting surface has an included angle there between.

  • Publication number: 20120280953
    Abstract: A display device including a display module, a light source module, a turning optical film, a first compensation film and a second compensation film is provided. The display module includes a first substrate, a second substrate and a display medium. The light source module generates directional light. The display module is disposed above the light source module. The second substrate is disposed opposite to the first substrate. The display medium is disposed between the first substrate and the second substrate and is optically isotropic. The turning optical film is disposed on the second substrate of the display module. The directional light enters the turning optical film and then exits the turning optical film to form an output light. The first compensation film is disposed on the first outer surface of the first substrate. The second compensation film is disposed between the second substrate and the turning optical film.

  • Publication number: 20120113357
    Abstract: Method, system and device for a transflective liquid crystal display with both transmissive and reflective functions is realized by using a transflective component into a transmissive LCD. The transflective component can be a transparent substrate with patterned reflectors on one surface and repetitive patterned lenses or prisms formed on the opposite surface facing the backlight unit. The transparent areas substantially allow the optical beams to pass through. The light from the backlight is refracted or focused by the optical structures onto the transparent areas or apertures of other surface, thus a substantial amount of backlight transmits to the LC for light modulation for different gray levels. For the incident ambient light incident on the transflective component, the majority is reflected back to the viewer by the reflectors on the transflective component, and the remainder transmits the transflective component to the backlight unit and be recycled to be used again.
