摘要： A parallax barrier includes a polarisation modifying layer having aperture regions, for supplying light of a second polarisation when receiving light of a first polarisation, separated by barrier regions, for supplying light of a third polarisation different from the second polarisation when receiving light of the first polarisation, and a polariser selectively operable in a first mode and a second mode. At least one of the aperture regions and the barrier regions alters the polarisation of light passing therethrough. The polariser passes light of the second polarisation and blocks light of the third polarisation in the first mode and passes light of the third polarisation in the second mode.

摘要： A 3D printer comprises a scanning laser system. A donor sheet is located in the focal plane of the optical system and carries a thermally transferable colourant such as a dye or pigment. A lenticular screen has a colourant receiving layer which receives colourant from the donor sheet to form 3D pixels, each comprising interlaced 2D pixels, aligned with lenticules of the screen. A detector array responds to laser light which has been transmitted through the lenticular screen, and a print register control system uses the detector output correctly to position the scanning laser beam to compensate for irregularities in the lenticular screen.

摘要： A passive polarisation modulating optical element comprises a layer of birefringent material. The layer has substantially fixed birefringence and comprises retarder regions forming a regular pattern, for instance to act as a parallax barrier for a 3D display. The retarders have optic axes aligned in different directions from each other. The element may be associated with a polariser, for instance an output polariser of a liquid crystal device, with the polarising direction of the polariser being parallel to the optic axis of the retarders. Thus, the retarders have no effect on the intensity of light passing through the element whereas the retarders act as half waveplates and rotate the polarisation vector of light passing therethrough, for instance by 90.degree..

摘要： A spatial light modulator comprises a plurality of picture elements arranged as rows and columns. The columns are arranged as adjacent groups, for instance for association with an element of a parallax device to provide an autostereoscopic 3D display. Adjacent picture elements disclosed in each row and in adjacent columns of each group overlap horizontally so that there are overlapping regions and non-overlapping regions. The vertical extent of each picture element is substantially constant throughout the non-overlapping region and is substantially equal to the sum of the heights of the adjacent picture elements throughout the overlapping regions.

摘要： In order to provide an active matrix liquid crystal spatial light modulator suitable for use in autostereoscopic displays, the conventional delta arrangement of liquid crystal pixels is formed. However, instead of forming the conventional black mask, a new type of black mask is provided. This black mask defines groups of two or more columns of pixel openings such that the columns of each group are substantially contiguous.

摘要： Disclosed is an optical valve or light valve for providing large area collimated illumination from localized light sources, and system and method thereof for 2D, 3D, and/or autosteroscopic displays. An optical valve may include a stepped structure, in which the steps include separated extraction features which may be optically hidden to light propagating in a first direction. Light propagating in a second direction may be refracted, diffracted, or reflected by the features to provide illumination beams exiting from the top surface of the optical valve. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality.
