System and methods for allowing a person or a process to select between multiple spatial-temporal sub-channels provided within a multi-sub-channel video-audio stream being output to a viewer, where selection causes a specific sub-channel within the stream to be received when viewing through an active filter device. A single image of the stream comprises at least two spatial sub-channels and the stream comprises at least two temporal sub-channels, where spatial sub-channels are formed using polarization and restrictive narrow-band color filtering. The stream is output by a display or projector and viewed using an active filter device. The active filter device comprises a combination of an active spatial channel filter and an active temporal channel filter and is responsive to sub-channel selections indicated through either a manual or automatic content selection means, where an automatic selection means includes a program for example directing the person through an adjustable story movie.

Systems and methods are described for mirroring 3D content from a first display (which may be a handheld 2D display) to a second display (which may be a 3D display, such as a light field display). The 3D content is initially displayed (e.g. as a 2D projection) on a the first display. The relative positions and/or orientations of the first and second displays are determined. The position of a user viewing the content may also be determined or may be inferred from the position and orientation of the first display. The second display is provided with information used to display the 3D content with a size and/or orientation that preserves the original apparent size and/or apparent orientation of that content from the perspective of the user.

Embodiments of the present invention provide a computer system, a computer program product, and a method that comprises identifying a first user of a plurality of users; identifying a location for the first user; transmitting input of the first user to a server computing device; and simultaneously displaying multiple personalized, dynamic displays using diffraction grating based off of input of the first user and location of the first user.

In one implementation, a method of operating a lenticular display is performed by a device including a processor, non-transitory memory, an image sensor, and a lenticular display. The method includes displaying, via the lenticular display, first content at a horizontal angle of a first user and second content, different than the first content, at a horizontal angle of a second user. The method further includes displaying, via the lenticular display, the first content at a second horizontal angle of the first user and the second content at a second horizontal angle of the second user.

A multi-view display device is provided. The multi-view display device includes a display panel having a plurality of pixels disposed in a matrix arrangement, adjacent first and second pixels of the plurality of pixels constituting a group pixel; a barrier disposed on the display panel and having an opening that transmits light and a shielding portion that shields light; and a driver configured to selectively drive the display panel in a normal driving mode, a narrow viewing angle mode, and a multi-view mode by controlling signals applied to the first and second pixels. The opening is overlapped with the first pixel, and the shielding portion is overlapped with the second pixel.

An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. The directional backlight may be arranged to switch between at least a first wide angular luminance profile mode and a second narrow angular luminance profile mode. The directional backlight is arranged to illuminate an LCD with a bias electrode arranged to switch liquid crystal directors in black state pixels between a first wide angular contrast profile mode and a second narrow angular contrast profile mode. Performance of privacy operation for off-axis snoopers is enhanced in comparison to displays with only directional backlights or switchable contrast properties.

An imaging directional backlight apparatus includes a waveguide and light source array for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure in which steps may include extraction features optically hidden to guided light, propagating in a forward direction. Returning light propagating in a backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and defines the relative positions of system elements and ray paths. Alignment of the waveguide to mechanical and optical components may be provided by surface relief features of the waveguide arranged in regions adjacent the input surface and intermediate the light emitting regions of the light sources. Efficient, uniform operation may be achieved with low cross talk for application to autostereoscopic and privacy modes of operation.

A privacy display comprises a luminance-privacy arrangement and a contrast-privacy arrangement. In a privacy mode of operation, ambient light levels are detected and a visual security level is calculated. At and above a visual security level threshold the luminance-privacy arrangement is operable and below the threshold both the luminance-privacy and contrast-privacy arrangements are operable. Image quality for on-axis users is optimised and high levels of visual security are achieved for off-axis snoopers over a wide range of display illuminance conditions.

Disclosed is an imaging directional backlight including an array of light sources, and a control system arranged to provide variable distribution of luminous fluxes, scaled inversely by the width associated with the respective light sources in the lateral direction, across the array of light sources. The luminous intensity distribution of output optical windows may be controlled to provide desirable luminance distributions in the window plane of an autostereoscopic display, a directional display operating in wide angle 2D mode, privacy mode and low power consumption mode. Image quality may be improved and power consumption reduced.
