    摘要: In a color liquid crystal projection display in which three differently-colored illuminating beams (R,G,B) are incident from mutually different directions on an LC panel (20) having an array of display elements (40) with a microlens array (21) at the input side of the panel end of whose elements (42) overlies a respective group of three adjacent display elements in row or delta configuration and through each of which light of the three colours (R,G,B) is directed at different angles respectively and converged towards respective ones of the display elements in its associated group, a deflecting element array (25), comprising, for example, microlens element (44) or microprisms (46) formed in a glass substrate of the panel, is positioned close to the plane of the display elements to deflect the directions of light of at least two of the three colours from each microlens element (42) to bring the directions of light of the three colours at the output side of the panel towards a common direction, and preferably substantially parallel to one another. A significant reduction in the amount of spread of light if the output side is thereby achieved, such that, inter alia, a comparatively small aperture projection lens (30) can be used.

    摘要: A process for making a mould piece having a main curved surface bearing an utilitary microstructure which comprises transferring a utilitary microstructure from a master piece main surface to a main surface of a flat cured elastomeric film; pressing the cured elastomeric film and a master article against each other so as to conform the overall shape of said cured elastomeric film to the curved shape of the main surface of the master article and to spread over a curable coating composition between the curved main surface of the master article and the main surface bearing the replica of the said utilitary microstructure of the cured elastomeric film; curing the coating composition; removing the cured elastomeric film and depositing a layer of a metal or a metallic alloy on the exposed main surface of the hard coating of the master article; and recovering said metal or metallic alloy layer to obtain a mould piece having a curved main surface bearing a replica of said transferred utilitary microstructure.

    摘要: Embodiments of the present invention relate to a cholesteric liquid crystalline material which may be usable in an electro-active element for providing fail safe operation, polarization insensitivity, low electrical power consumption requirements, and a small number of electrical connections. The cholesteric liquid crystalline material may be usable in an electro-active element for providing a diffractive efficiency or focusing efficiency above 90% in an activated state of the electro-active element and a diffractive efficiency or focusing efficiency below 10% in a deactivated state of the electro-active element.
