A foil structure with generation of visible light via LED technology has a carrier foil and an LED chip for generation of UV light. The LED chip is disposed on a first portion of the carrier foil and is provided with a light output face for emission of the UV light. The foil structure further has a color reaction layer for conversion of the UV light into the visible light, wherein the color reaction layer is disposed on a second portion of the carrier foil. The carrier foil is folded over in such a way that the second portion of the carrier foil is disposed above the first portion of the carrier foil and the color reaction layer is disposed above the LED chip or in a manner laterally offset relative to the LED chip.

Foil structure with generation of visible light by means of LED technology

A foil structure with generation of visible light using LED technology includes a carrier foil and an LED chip for generation of UV light. The LED chip is disposed on the carrier foil and is provided with a light output face for emission of the UV light. Furthermore, the foil structure includes a color reaction layer for conversion of the UV light into the visible light. The color reaction layer is disposed above the LED chip or in a manner laterally offset relative to the LED chip. The color reaction layer is provided with a structuring, so that the UV light emitted from the light output face of the LED chip is not emitted into the surroundings of the foil structure.

A sensor device for integration in an electrical circuit, including a support layer ('), which is formed with a release layer; at least one flexible insulating layer (), which is made using a printing method; and at least one flexible electrical conductor structure (), which is applied with a printing method onto the insulating layer (). The insulating layer () and the conductor structure () form a flexible unit, which is removable without damage from the support layer (&#x2032;).

An electrode layer () formed by a transparent conductive varnish is applied to a mineral or plastic glass carrier. Afterwards, a luminescent layer () formed by a transparent matrix () provided with electroluminophors () incorporated therein is disposed within contours defining an image surface. Said luminescent layer () is dividable into several discrete partial areas. A rear silver-containing electrode layer () extends within the a luminescent layer () contours above a surface whose size is approximately equal to the size of the luminescent layer () but leaves a narrow edge area () thereof free. The structure also comprises an insulating transparent layer () provided with recesses () in the area of the rear electrode layer () in order to bring it into contact for voltage supply from a rear face. Said rear electrode layer () is brought into contact through the recesses () of the insulating layer () by means of a transparent conductive varnish contact layer (). The inventive electroluminescent display is insulated on the rear face thereof by a rear transparent insulating layer ().
