Abstract: An addressable receptor in laminate form, and advantageously in PTF laminate form, comprising a front conductive layer including a plurality of substantially parallel front electrode strips and a rear conductive layer also including a plurality of substantially parallel rear electrode strips. The conductive layers are orientated with respect to each other so that an array of electrode regions of intersection is formed corresponding to the regions at which the front electrode strips cross over the rear electrode strips. The first and second conductive layers are separated by a reactive layer comprising a plurality of defined reactive regions. The reactive regions are deployed in a reactive array substantially in register with the array of electrode regions of intersection, so that the reactive regions are electrically addressable by coordinate pairs of first and second electrode strips. The front electrode strips are partially transparent to radiation in a selected waveband.

Abstract: A polymer Thick Film (“PTF”) laminate, in which selected (and advantageously all) of the layers are deployed using UV-curable inks. In one embodiment of the invention, the UV-curable PTF layers are deployed in an exemplary monolithic and membranous EL structure, in which UV-cured urethane envelope layers encapsulate UV-cured urethane electroluminescent layers. When deployed in layer form during manufacture and subsequently exposed to UV radiation, the inventive inks cure in a few seconds without any appreciable layer height shrinkage. Manufacturing cycle time is significantly optimized over traditional heat curing processes. Flexible circuitry is also disclosed herein. The flexible circuitry may be embodied using the UV-curable urethane inks disclosed herein, although the flexible circuitry is not limited to UV-curable or urethane embodiments. Successive insulating layers are deployed. The insulating layers have conductive pathways deployed thereon.

Abstract: A membranous electroluminescent structure including membranous envelope layers encapsulating electroluminescent layers. The envelope layers comprise a UV-curable ink, such as a urethane acrylate/acrylate monomer. When deployed in layer form and exposed to UV radiation, the ink cures in a few seconds without any appreciable layer height shrinkage. Manufacturing cycle time is significantly optimized over traditional heat curing processes. The resulting membranous UV-cured EL structure nonetheless has all the advantages of membranous EL structures.

Abstract: A membranous electroluminescent structure with selected layers suspended, prior to deployment, in a carrier comprising (1) a vinyl resin in gel form and (2) a polymeric hexamethylene diisocyanate catalyst. During curing, the catalyst facilitates transformation of the vinyl resin carrier into a urethane. Once cured, the transformed urethane carrier compound enables electroluminescent layers to bond in a monolithic structure also comprising other contiguous urethane layers, such as envelope layers. As a result, membranous electroluminescent structures made in accordance with the present invention are even more rugged than their predecessors. A high degree of crosslinking also becomes available between neighboring urethane layers.

Abstract: A polymer thick film (PTF) electroluminescent device generating images described by contact, in which the contact itself closes an open circuit to generate radiation in a pattern in register with the contact. The resulting irradiated image corresponds directly to the contact pattern energizing the radiation. In a preferred embodiment enabled by an electroluminescent system without a back electrode, a fingerprint is disposed to close the open circuit by making contact and thereby serving as a “temporary” back electrode. The electroluminescent then energizes in a pattern in register with the contact (i.e. the fingerprint) to emit a high-resolution image of visible light with high fidelity to the contact. This visible light image may then be directed on to a photosensitive array standard in the art suitable for pixelation and conversion into an electrical signal representative of the image. This signal is available for computerized storage, analysis, processing and comparison.

Abstract: An electroluminescent system in which neighboring layers are suspended, prior to application, in advantageously a unitary carrier compound, so that after curing, the layers form active strata within a monolithic mass. The carrier compound in a preferred embodiment is a vinyl resin in gel form. The invention enables several manufacturing advantages, including the ability to screen print the entire electroluminescent system on a variety of porous or fibrous substrates.

Abstract: A method for treating a deployed conductive translucent layer that includes exposing the layer to ultra-violet (“UV”) radiation for the design purpose of increasing the conductivity of the layer. The layer advantageously includes a metal oxide dopant such as an indium-tin-oxide. The invention includes exposing the layer to UV radiation both during and/or after curing. The exposure to UV radiation has been shown to increase the conductivity of the layer without appreciably affecting the translucence. In one embodiment, the method includes confining the exposure to UV radiation to preselected zones on the layer so as to create pathways of increased conductivity on the layer.

Abstract: A device generating images described by three dimensional contact (such as the grip of a human palm), in which the contact itself closes an open circuit to generate radiation in a pattern in register with the contact. The resulting irradiated image corresponds directly to the contact pattern energizing the radiation.

Abstract: Apparel is disclosed, including an elastomeric electroluminescent (EL) lamp in which an electroluminescent system, advantageously monolithic, is provided in an elastomeric structure. As a result, the lamp is thin, pliable and membrane-like. A first envelope layer is applied advantageously by screen printing to transfer release paper. An EL system is then applied, again advantageously by screen printing to the first envelope layer, and then a second envelope layer is applied to seal the EL system within the envelope. Appropriate windows are cut or left open to allow electrical contact with the EL system. An optional adhesive layer then may be applied if the lamp is to be used in transfer form for later affixation to the apparel.
