A multi-view display includes a view forming arrangement having a first view forming structure spaced by a first distance from a display panel for providing multiple views across a first direction, and a second view forming arrangement spaced by a second distance from the display panel for providing multiple views across a second perpendicular direction. An angular width of the multiple views in the two directions can thus be independently defined.

An optical connector system for reversible optical connection between two optical fibers () with their end parts inside respective ferrules. A receptacle arrangement has a receiving body () for receiving at least one of the ferrules (). An optical element () of the receptacle arrangement serves to provide optical connection between the two optical fibers in a connected state of the optical connector system, and at the same time, the optical element () serves as a sterility barrier between the two optical fibers. The optical element () can be an optical waveguide, e.g. a piece of optical fiber similar to the two optical fibers (), and arranged within the receiving body (). Alternatively, the optical element may be a thin flexible membrane () which is optically transparent. As a further alternative, the optical element may be a sterilizing fluid () arranged in side a container that can be punctured upon insertion of one of the ferrules () into the container (), to allow an optical fiber end to be sterilized by the fluid () prior to entering into the connected state. In a further embodiment, an optical lens () is used to project light from one fiber end through a membrane () to the opposite fiber end.

An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a hexagonal grid, and the lenses also repeat in a hexagonal grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimensional space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

Autostereoscopic display device

A display backlight comprises an edge-lit waveguide having an array of light out-coupling structures which for example each comprise a projection into the waveguide. Each projection has a beam redirecting face which is at an angle a to the normal. The angle a and the refractive index of the waveguide as well as outside the waveguide (over the output face) are designed to satisfy various relationships, which ensure that the optical output can be selected to be within a desired angular range in a generally forward direction (and thus not clipped).

Display device with directional control of the output, and a back light for such a display device

A display backlight comprises an edge-lit lightguide having an array of light out-coupling structures to enable light to escape from the lightguide at the location of the light out-coupling structures. A light source arrangement is used for providing light into the lightguide at one or both of the opposite side edges. The light source arrangement is controllable to provide a selected one of at least first and second light outputs into the lightguide, the two light outputs having a different angle to the general plane of the lightguide and resulting in light which escapes from the lightguide with a different range of exit angles. In this way, a directional backlight output is enabled, based on the way light is coupled into a lightguide. This provides a simple structure only requiring control of the light provided to the lightguide. The backlight may for example enable an auto stereoscopic display to be formed without the need for a lenticular array.
