Publication number: 20240123757Abstract: A laminate with a decorative layer over an electrical functional layer such as a touch sensor panel, which provides for example a touchpad functionality, as well as a production method for it. It is possible for the first time to perform an individualization of prefabricated laminates with functionality such as touch functionality of a touch sensor in an uncomplicated manner. This is achieved by supplementing a functional laminate with a laser protective layer between the electrical functional layer and a decorative layer which can be lasered and written on with simple measures.Type: ApplicationFiled: February 22, 2022Publication date: April 18, 2024Inventors: Wolfgang CLEMENS, Martin HAHN, Jörg STIERAND, Mathias GRUBER, Johannes SCHAD

Patent number: 10884523Abstract: A film, a method for producing a film, the use of a film for application to a target substrate as well as a method for producing an electrical functional element. The film here includes a carrier substrate, an adhesion-promoting layer for applying the film to a target substrate, and at least one electrically conductive layer, wherein the at least one electrically conductive layer forms an electrical functional structure in a functional region, wherein the at least one electrically conductive layer forms at least one contacting structure for contacting the electrical functional structure in at least one contacting region, and wherein the adhesion-promoting layer does not cover the at least one contacting region at least in areas when viewed perpendicularly to a plane spanned by the carrier substrate or wherein the adhesion-promoting layer is applied over the whole surface when viewed perpendicularly to a plane spanned by the carrier substrate.Type: GrantFiled: November 21, 2016Date of Patent: January 5, 2021Assignee: LEONHARD KURZ STIFTUNG & CO. KGInventors: Matthias Heinrich, Andreas Hirschfelder, Martin Hahn, Johannes Schad

Patent number: 9465261Abstract: The invention relates to a display device (10), in particular in the form of a multi-layer film body. The display device (10) has, in a first area (22), a first electrode (41), a second electrode (42), a third electrode (43) and a display layer (122) with a display material. The display layer (122) is arranged between the first electrode (41) and the second electrode (42). The third electrode (43) is arranged on the side of the display layer (122) facing away from the first electrode (41). The first electrode (41) is formed as an isolated electrode. The first electrode (41) overlaps both the second electrode (42) and the third electrode (43) at least in areas when viewed perpendicular to the plane spanned by the display layer (122).Type: GrantFiled: October 16, 2012Date of Patent: October 11, 2016Assignees: POLYIC GMBH & CO. KG, LEONHARD KURZ STIFTUNG & CO. KG, OVD KINEGRAM AGInventors: Rainer Stahl, Klaus Ludwig, Johannes Schad, Wayne Robert Tompkin

Patent number: 8896501Abstract: The invention relates to a security element for the identification of a security document, in particular a banknote, a valuable paper or a paper document, comprising at least one electrically controllable display element and at least one piezoelectric energy source which controls the at least one display element. The security element is formed by a flexible multilayered film body comprising the at least one electrically controllable display element containing a display layer having liquid crystals that can be oriented in an electric field, and comprising the at least one piezoelectric energy source which controls the at least one display element and has at least one layer composed of piezoelectric material, wherein the security element has a thickness of at most 70 ?m in a direction perpendicular to the plane of the film body.Type: GrantFiled: September 16, 2008Date of Patent: November 25, 2014Assignee: Poly IC GmbH & Co. KGInventors: Rainer Stahl, Gerrit Hackl, Steffen Weiss, Klaus Ludwig, Johannes Schad

Patent number: 8604907Abstract: The invention concerns a multi-layer flexible film body (6), in particular a label film or packaging film as well as a goods identification system and uses of such a film body. The film body (6) has a carrier layer and a decorative layer system (11) which provides optically recognisable information. A plurality of layers of the decorative layer system form an electronically controlled display element (65), by the activation of which the optically recognisable information becomes visible.Type: GrantFiled: September 11, 2008Date of Patent: December 10, 2013Assignees: PolyIC GmbH & Co. KG, Leonhard Kurz Stiftung & Co. KGInventors: Klaus Ludwig, Wolfgang Clemens, Johannes Schad
