  • Patent number: 6551726
    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.

  • Publication number: 20030017371
    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.

  • Publication number: 20010055412
    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.

  • Patent number: 6309764
    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.

  • Patent number: 5856031
    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, whose inherent thixotropic properties lend themselves to pre-suspending ingredients in the unitary carrier. The suspended ingredients may then be provided in kit form, ideally in the correct volumetric proportions. The invention enables several manufacturing advantages, including the ability to screen print the entire electroluminescent system on a variety of substrates, including cloth, metals, plastics, wood or even stone.
