Abstract: Disclosed is an imaging directional backlight apparatus comprising a waveguide, a light source array, and a further optical element for providing large area directed illumination from localized light sources. The imaging directional backlight may comprise a stepped waveguide that 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. Viewing windows are formed through imaging individual light sources. The further optical element may comprise a superlens comprising first and second aligned lens arrays that may be arranged to modify the output viewing windows to achieve enhanced window imaging from the directional backlight.

Abstract: An autostereoscopic display apparatus may include a stepped waveguide, optical elements, and one or more reflective imaging and/or directional elements. These elements may be arranged to return light from the stepped waveguide into an array of viewing windows. Such elements can be used to achieve observer tracking autostereoscopic display for landscape and portrait modes of operation. System thickness and cost may be reduced and system brightness can be increased or low operating power modes may be achieved.

Abstract: Disclosed herein are displays and related methods for providing stereoscopic imagery, wherein an air gap may be provided between components of the display to allow a reduction in the amount of bonding material used to bond a stereoscopic display panel with a polarization control panel (PCP) element comprising an active switchable retarder. In some embodiments, the PCP element is at least the size of the display panel such that the entirety of the display panel is covered by the PCP element, and thus there would be neither tight tolerance horizontal nor vertical alignment requirements between the PCP element and the display panel. Structural support of the components of the display may be provided by bonding around the edges of the rigid or semi-rigid stereoscopic display panel and PCP element. For example, the air gap may be created with uniform spacers between the stereoscopic display panel and the PCP element.
