Abstract: A flexible electrooptic display material comprising two sets of elongated elements. The first set elements are tape yarns comprising a layer of electrooptically active (EOA) substance, one or more transparent conductive layers disposed on one side of the EOA layer, and a transparent carrying layer. The elements of the second set comprise at least a conductive layer. The two sets form a matrix display structure in which the elements of each set are in contact with the elements of the other set. Single display elements (pixels) are formed in the overlapping regions between the elements where the EOA substance is disposed between a conductive layer of a first set yarn and a conductive layer of a second set element. The two sets of elements are preferably interlocked in woven arrangement, and preferably two sets of tape yarns having the same structure are used.

Abstract: A method of manufacturing a multi-layer optical information carrier with fluorescence reading/recording is presented. A structure is fabricated, being formed of a substrate carrying a fluorescent film on one or both surfaces thereof, wherein the substrate is transparent with respect to incident radiation used for the fluorescence reading/recording. A patterned structure is applied to the fluorescent film under predetermined process conditions, such as to produce a fluorescent patterned structure with a surface relief in the form of an array of discrete fluorescent regions. The same procedure is repeated a required number of times, so as to obtain at the end of the process a multi-layer optical information carrier.
