Abstract

The invention relates to a novel concept for the production of an encapsulated and at least partly organic electronic unit. Said unit embodies a novel concept for the combination of different electronic components to form an electronic unit, such as antennae, diodes (rectifier diodes and/or light-emitting diodes), transistors, etc. and a circuit, which is optimized therefore. According to the invention, similar components of the unit and/or the circuit are combined to form an arrangement on a substrate (region) and/or in an encapsulation, said arrangement being then electronically interconnected.

Claims

1. Organic electronic unit comprising at least three groups of components:

one group comprising essentially inorganic units,

one group of passive units,

one group of active units, wherein

the group comprising passive units contains no active units or components and the group of active units essentially contains organic field-effect transistors, wherein the three groups can be produced independently from one another, wherein said units are connected via electric contact on a substrate and/or via encapsulation forming a circuit, through which electrical contacts run between passive and active units from one group to another.

2. Organic electronic unit in accordance with claim 1, wherein the substrate and/or the encapsulation is a flexible film.

3. Organic electronic unit in accordance with claims 1 or 2, wherein at least one electronic contact is produced through gluing and/or by means of an electrically conductive adhesive.

4. Utilization of an organic unit in accordance with one of the claims 1 through 2 including an RFID tag, inside the RFID tag are a sensor array and a photovoltaic cell, wherein the tag is useful as any one selected from the group consisting of wearable electronics, an active display, an electronic bar code, an electronic watermark, an electronic stamp, a bag tag and an electronic ticket.

5. Organic electronic unit in accordance with one of the claims 1 and 2, wherein a circuit, comprising the following components:

an antenna, a first capacitor, a diode, and a modulation transistor in front of an integrated circuit, in which a second and a third capacitor and an additional diode are switched in such a way as to supply the integrated circuit via the second capacitor, and where, at the same time, the additional diode prevents said modulation transistor (4) from depriving said second -capacitor with energy, is produced.

6. A method to produce an organic electronic unit comprising at least one group with an antenna, a passive group and an active group, said antenna, passive and active groups being pre-assembled separately, the circuit then being assembled through simple electric interconnection of the individual groups.

7. A method to produce an organic electronic unit in accordance with claim 6, including a capacitor on a substrate film, conductive regions on the antenna and an encapsulation film wherein a conductive polymeric region capable of metallization is generated for the capacitor on the substrate film in such a way as to create capacity by means of said region and conductive regions on the antenna after assembling the substrate film and active and passive groups or the encapsulation film.
