Abstract: A visual display panel (1) comprising: a front face (3); an array of optical display elements, a plurality of fluid flow conduits, each conduit extending through the panel from an aperture on the front face; and a manifold (32) in fluid communication with one or more of the plurality of fluid flow conduits, the manifold having one or more manifold inlets (38) fluidly coupled to a fluid pump (33) for displacing fluid through the conduits.

Abstract: A switchable autostereoscopic display device comprises a display panel having an array of display pixel elements for producing a display, the display pixel elements being arranged in rows and columns. An imaging arrangement directs the output from different pixel elements to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement is electrically switchable between at two 3D modes, wherein the effective position of the imaging arrangement is shifted laterally between the modes with respect to the display pixel elements by an amount which is a non-integer multiple of the pitch between the pixel elements. These two modes enable the resolution per mode to be increased, by adding views at inter-pixel locations, or enables the number of views to be increased.

Abstract: The present invention relates to a camera arrangement as for instance used in a mobile phone that utilizes a liquid crystal based lens for providing an adjustable depth of focus. The camera arrangement comprises a photo sensor (201) array and at least two lenses (202, 203, 204) that are arranged in a fixed and unitary arrangement. At least one of the lenses (202) comprises a liquid crystal layer (101) that provides for adjustable focal length in that lens. The additional lens(-es) (203, 204) might have fixed or adjustable focal length depending on the application. According to one embodiment, the camera arrangement comprises at least one additional adjustable lens ant the lenses are arranged so as to provide for adjustable depth? of focus as well as for an adjustable depth of field.

Abstract: The invention relates to a method of manufacturing a replica, which method comprises the provision of a polymerizable resin composition between a front mold having a pre-shaped surface and a back mold having a pre-shaped surface, carrying out a curing treatment and removing the replica thus manufactured from the molds. The invention further relates to a replica obtained by carrying out a UV light-initiated cationic polymerization.

Abstract: The invention relates to a method of manufacturing a replica, which method comprises the provision of a bondable resin composition between a mold and a substrate or a blank, carrying out a curing treatment and removing the replica thus manufactured from the mold, which replica comprises the substrate and the reproduction of the mold provided thereon. The invention further relates to a replica obtained by carrying out a UV light-initiated cationic polymerization.

Abstract: In a method of manufacturing a replica, a bondable resin composition is provided between a mold and a substrate or a blank, the resin is cured and the replica thus manufactured is removed from the mold. The replica includes the substrate and the reproduction of the mold on the substrate. The curing includes a UV light-initiated cationic polymerization.
