Abstract: The present invention relates to optical elements comprising fluorochemical surface treatments. The invention further relates to materials such as retroreflective sheetings, pavement markings and beaded projection screens comprising a binder and the surface treated optical elements. The fluorochemical surface treatment is substantially free of perfluoroalkyl groups having more than four carbon atoms. Preferably, the surface treatment is a polyfluoropolyether-based compound comprising at least one polar group or polar group-containing organic radical.

Abstract: Plasma addressed liquid crystal display ribs are produced by introducing a glass paste which includes a curable medium into cavities formed in an intaglio collector to define rib structures, which are transferred from the collector to a surface of a substrate, and removing the curable medium from the rib structures on the substrate surface to generate pores in the rib structures. The substrate having rib structures is then dipped into a solution containing an opaque pigment which is absorbed into the rib structure.

Abstract: An assembly of rib structures sandwiched between a dielectric glass layer and a glass substrate for use in a flat panel display, such as plasma addressed liquid crystal (PALC) displays, is formed by a number of methods. One method includes molding thermoplastic glass frit containing paste into rib structures, transferring the rib structures to a thin transparent layer of a thermoplastic dielectric glass frit containing composition on a drum, and transferring the rib structures with the thin transparent dielectric glass layer to a glass substrate having metallic electrodes already formed thereon.

Abstract: In a method of manufacturing a ferroelectric liquid crystal device, the following steps are applied in order to effect spacing apart of two substrates and by spacers. The spacers are applied to a surface of a transfer member, and the transfer member is then pressed onto a receiving surface of one of the substrates. The transfer member is then removed so as to transfer the spacers from the transfer member to the receiving surface at the required positions. Finally the other substrate is pressed onto the spacers on the receiving surface so as to form an assembly of the two substrates spaced apart by the spacers. Such a sequence of steps enables the spacers to be placed in the required positions in a particularly straightforward manner, whilst minimising the number of fabrication steps used in the process.

Abstract: In the method of fabricating a CRT including a sputtering method for forming an anti-static layer and a spin-coating or spray-coating method for forming an anti-reflection layer on a CRT panel, a method of fabricating a low-resistance, anti-reflection CRT is characterized by applying a silicon oxide (SiO2) coating between the anti-static layer and the anti-reflection layer by a sputtering method. As a result, the CRT has enhanced strength of layers and a low surface resistance. Also, the screen is provided with a charge protection function in the surface, with reflectivity of an external light being mitigated. As a result, it is possible to enhance the contrast characteristics of the screen, to avoid leaving fingerprints on the screen, and also to eliminate unpleasant feeling of static electricity.
