摘要： In one aspect, there is provided an apparatus. The apparatus may include a waveguide layer to guide an optical beam, and a lenslet layer, coupled to a surface of the waveguide layer, to focus a portion of the optical beam. The apparatus may further include a first active layer, coupled to another surface of the waveguide layer, to allow the portion of the optical beam to decouple from the waveguide layer by passing through the first active layer in at least one selectable region of the first active layer. The apparatus may further include a redirecting layer, coupled to or proximate to the first active layer, to redirect the portion of the optical beam decoupled from the waveguide towards the lenslet layer.

摘要： In a light guide device, a step between optical surfaces connected to each other by a connection portion can be limited (e.g., to 1 mm or smaller) so that a large stepped portion is not allowed to be formed at the connection portion in a hard coat formation process, whereby a coating liquid that flows along portions that are to form the optical surfaces forms no liquid pool or causes no liquid sagging. The light guide device can thus maintain satisfactory light guiding performance at the light guide portion.

摘要： 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.

摘要： Disclosed is a light guiding valve apparatus including at least one transparent stepped waveguide optical valve for providing large area collimated illumination from localized light sources, and at least one further illumination source. A stepped waveguide may be a stepped structure, where the steps include extraction features 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. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality. Light from a separate illumination source may pass through the transparent stepped waveguide optical valve to provide at least one further additional illumination function.

摘要： Backlit display systems, such as those employed with LED backlit displays, including those configured for autostereoscopic operation, may employ synchronization between the backlight and the presentation of sequential left and right eye images at a frame rate exceeding approximately 100 Hz. To successfully directionally illuminate isolated frames, the disclosed principles provide for segmenting the directional illumination and introducing a phase shifted, synchronized, pulsed drive scheme for the illumination segments. Accordingly, the principles disclosed herein are directed to segmented directional illumination systems and related techniques for segmented directional backlight illumination.
