摘要： The invention relates to an illumination system (4) comprising at least one light source (10) for emitting light of a predominant wavelength (W), and a light-transmitting panel (14) which comprises a light-emitting window (16), a rear wall (18) situated opposite said light-emitting window, and edge walls (20) extending between the light-emitting window and the rear wall. Light from the LED is coupled into the light-transmitting panel and is transported substantially via total internal reflection. The rear wall is provided with a two-dimensional array of recesses (22, 24). A sub-set of recesses (22) is distributed substantially regularly on the rear wall. Each recess (22A, 22B, 22C) from the sub-set (22) comprises scattering material (26). When light from the light-transmitting panel reaches the scattering material of the recess, part of the light (W′) is coupled out of the light-transmitting panel via scattering. The regular distribution of the scattering material on the rear wall improves the uniformity of the light emitted via the light-emitting window. In an embodiment of the illumination system, the scattering material comprises a luminescent material (28), which absorbs light of the predominant wavelength (UV) and emits light of a further predominant wavelength (R, G, B).

摘要： A display device includes a display panel having separately addressable pixels for displaying an image. A first pixel group of provides emergent light in a first polarization state, and a second pixel group provides emergent light in a second polarization state. A barrier layer in optical association with the display panel partially occludes the emergent light. The barrier layer has a first set of regions for passing light in one of the first or second polarization states, a second set regions for passing light in the other polarization state, and a third set of regions for occluding the emergent light. The first and second regions of the barrier layer are respectively registered with the first and second groups of pixels so as to provide different views of an image displayed by the display panel.

摘要： An optical path length adjuster enables electro-optical control of a physical path length between two optical elements, suitable for use in the adjustment of an optical path length within three dimensional display devices that generate a virtual image within a defined imaging volume. The adjuster varies an optical path length between an input optical path and an output optical path and includes: a first polarisation switch for selecting a polarisation state for an input beam on the input optical path; first and second beam splitters having at least two possible optical paths of different lengths therebetween, for passing the input beam along a selected one of said at least two possible optical paths according to the selected polarisation state of the input beam and for providing an output beam of light, on said optical output path, that has traveled along the selected optical path.

摘要： A display comprises a display panel, a polarizer, a polarization rotator, and a scatterer arranged to scatter light having a first polarization as compared with a second polarization. The display can be switched between 2D and 3D modes by operating the polarization rotator. In 3D mode, the polarization rotator transmits light with relatively little change to its polarization. Light transmitted by the scatterer is used to present three-dimensional images. In 2D mode, the polarization rotator alters the polarization of the light, and light that is scattered by the scatterer is used to present a two-dimensional image. The polarization rotator may be arranged so that light incident on a first area thereof undergoes a different change in polarization to light incident on a second area, to simultaneously present 2D and 3D images.
