Patent number: 10305067Abstract: The invention relates to a substrate (2) for manufacturing an organic conversion device for converting electrical energy into light energy or light energy into electrical energy, wherein the substrate comprises a) an encapsulation layer (3) on the substrate, wherein the encapsulation layer includes a first inorganic layer (7), a second inorganic layer (9) and an intermediate organic layer (8), and b) a getter reservoir (6) in contact with the organic layer of the encapsulation layer. Water molecules will therefore not only be transported along the intermediate organic layer, but will also be gathered, especially absorbed, by the getter reservoir, if the encapsulation is damaged. This can slow down a transport of water molecules along a leakage path towards an organic conversion layer of the organic conversion device and hence slow down a possible degradation of the performance of the organic conversion device, if the encapsulation layer is damaged.Type: GrantFiled: August 4, 2015Date of Patent: May 28, 2019Assignee: OLEDWorks GmbHInventors: Stefan Peter Grabowski, Herbert Lifka, Peter Van De Weijer, Rainald Manfred Gierth, Jens Meyer, Manfred Stephan Ruske, Helga Hummel

Patent number: 9831467Abstract: The present invention relates to an encapsulated semiconductor device (20) provided on a flexible substrate (1), a method of providing an at least partially encapsulated semiconductor device (20) on a flexible substrate (1) and a software product for providing an at least partially encapsulated semiconductor device (20) on a flexible substrate (1). In a preferred embodiment, an encapsulation method is presented in which the organic layer (3) of an inorganic/organic/inorganic multilayer barrier (5) on a plastic foil (1) as a substrate is removed at the edges of an OLED (13). The edges are subsequently sealed with a standard TFE process to encapsulate the OLED (13). This enables cuttable OLEDs (20) that are cut out of a larger plastic substrate (1) and gives a method to reduce side leakage in OLEDs (20) that have been manufactured in a roll-to-toll process.Type: GrantFiled: January 13, 2015Date of Patent: November 28, 2017Assignee: OLEDWORKS GMBHInventors: Jens Meyer, Rainald Manfred Gierth, Stefan Peter Grabowski, Herbert Lifka, Peter Van De Weijer, Petrus Cornelis-Paulus Bouten, Volker Lambert Van Elsbergen, Manfred Stephan Ruske, Soren Hartmann

Patent number: 9780330Abstract: The invention relates to OLEDs (1) having a substrate (2), a first electrode layer (3), a layer of organic electroluminescence material (4), a second electrode layer (5), a cover layer (6), moisture-absorbing means (9) and a separating foil (10) of resilient material. According to the invention, said foil (10) is positioned between the second electrode layer (5) and the moisture-absorbing means (9). This feature results in a longer mean life-time of the OLED. Advantageously spacer structures (12) (preferably formed as dots) are applied on the separating foil (10) between the foil (10) and the cover (6). This prevents discoloring effects around the rim of the OLED material.Type: GrantFiled: July 5, 2016Date of Patent: October 3, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Herbert Friedrich Boerner, Rainald Manfred Gierth, Stefan Peter Grabowski, Petrus Cornelis Paulus Bouten, Peter Van De Weijer

Publication number: 20170271621Abstract: The present invention relates to a current-light conversion device (1), such as an OLED or an OPVD, wherein the current-light conversion device comprises a substrate (10), a current-light conversion arrangement (11) comprising a current-light conversion material (111) provided between a first and a second electrode layer (110, 112), and a barrier layer (12) comprising a transparent organic layer (121) provided between a first and a second transparent inorganic barrier layer (120, 122). A getter material is provided in the transparent organic layer (121) in a pattern of getter dots (1210). Since the getter material is provided in a pattern of getter dots (1210), the light scattering effect resulting from dispersed getter particles can be avoided, resulting in improved transparency characteristics of the barrier layer (12) while still providing the desired getter functionality.Type: ApplicationFiled: August 17, 2015Publication date: September 21, 2017Inventors: Herbert LIFKA, Roy Gerardus Franciscus Antonius VERBEEK, Petrus Cornelis Paulus BOUTEN, Peter VAN DE WEIJER, Matheus Godefridus Johannus BEL, Manfred Stephan RUSKE, Rainald Manfred GIERTH, Jens MEYER, Stefan Peter GRABOWSKI, Helga HUMMEL

Publication number: 20160111675Abstract: The invention relates to an OLED(1) comprising an etch stop layer (3) between a first electrode (2) and anorganic layer stack (4) and an electrically conductive element (13) arranged in an etched region (6) within a second electrode (5) and the organic layer stack such that the electrically conductive element is electrically connected with the first electrode. The etch stop layer is a hole-injection layer comprising a metal oxide with semi conducting properties. In particular, the OLED may comprise several electrically conductive elements in several etched regions, wherein the electrically conductive elements can be electrically connected with different parts of the first electrode and with each other via an electrical connector (14) for shunting the different parts of the first electrode, which can lead to a more homogenous light emission. The electrical conductive elements may also be used to provide a color tunability.Type: ApplicationFiled: May 15, 2014Publication date: April 21, 2016Applicant: KONINKLIJKE PHILIPS N.V.Inventors: Jens MEYER, Rainald Manfred GIERTH, Stefan Peter GRABOWSKI
