Patent number: 10120183Abstract: A display device or optical switch, based on layer break up or layer displacement having at least two different states, in which one fluid, e.g., oil, in a first state adjoins at least a first support plate, and in a second state another fluid at least partly adjoins the first support plate. Sub-picture elements are separated by areas having a hydrophilic surface.Type: GrantFiled: July 20, 2015Date of Patent: November 6, 2018Assignee: Amazon Technologies, Inc.Inventors: Bokke Johannes Feenstra, Robert Andrew Hayes, Ivo Godfried Jozef Camps

Patent number: 9470609Abstract: Apparatus for producing thin layers of a fluid sample for analysis, has a two dimensional array of analysis chambers (45), and a branching pattern of entry channels (25) coupled to the array to enable the analysis chambers to be filled in parallel. The analysis chambers are planar with a height less than that of the entry channels so as to produce the thin layers when filled with the fluid sample. The array enables more spacers between chambers in a given area, so that variations in height of the chambers can be reduced, while still enabling fast filling of the chambers. The analysis chambers can be suitable for capillary filling by a specified fluid sample such as blood. A pattern of exit channels (35) can be coupled to the array. The entry and exit channels can form comb patterns, fingers of the comb patterns being interdigitated, and the analysis chambers being arranged between the interdigitated fingers of the comb patterns.Type: GrantFiled: April 9, 2010Date of Patent: October 18, 2016Assignee: Koninklijke Philips N. V.Inventors: Reinhold Wimberger-Friedl, Nicolaas Petrus Willard, Ivo Godfried Jozef Camps, Markus Laubscher, Emiel Peeters, Oana Mihaela Piciu

Patent number: 7122957Abstract: An electroluminescent device (21) comprises a first (23) and a second (26) electrode layer, at least the second electrode layer (26) being provided in accordance with a desired pattern and one or more functional layers (24, 25R, 25G, 25B), the one or at least one of said functional layers being an electroluminescent layer. In order to pattern the second electrode layer (26) the EL device (21) comprises a relief pattern (27) having one or more overhanging sections (29). The EL device has means for hindering the transport of fluid along a capillary channel (33) formed by an overhanging section (29) and the surface (28a) supporting that section, an example of such means being protrusions (35) which block and/or reroute the capillary channel (33). Thus the transport of fluid by the channels (33) during manufacture of the EL device is hindered and color bleeding between pixels of the EL device and/or leakage current among electrodes of the first electrode layer is prevented.Type: GrantFiled: November 8, 2001Date of Patent: October 17, 2006Assignee: Koninklijke Philips Electronics N. V.Inventors: Paulus Cornelis Duineveld, Coen Theodorus Hubertus Fransiscus Liedenbaum, Eliav Itzhak Haskal, Ivo Godfried Jozef Camps

Patent number: 7011561Abstract: A method of manufacturing an electroluminescent device comprising forming a pattern, depositing a liquid, and processing the liquid to form an electroluminescent region. The pattern includes an overhanging structure with a negatively-sloped section thereunder and a functional region bounded on at least one side by a positively-sloped section. The overhanging structure is on a side of the positively-sloped section that is opposite the functional region. The liquid is suitable for forming a functional layer within the functional region such that the liquid contacts the a positively-sloped surface of the positively-sloped sections. The positively-sloped sections have a shape and size such that at least some of the liquid is prevented from reaching the negatively-sloped section and being taken up by a capillary channel of the negatively-sloped section.Type: GrantFiled: August 27, 2004Date of Patent: March 14, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Paulus Cornelis Duineveld, Ivo Godfried Jozef Camps, Coen Theodorus Hubertus Fransiscus Liedenbaum, Eliav Itzhak Haskal, Maria Henrica Wilhelmina Antonia Van Deurzen, Jochem Petrus Maria De Koning

Patent number: 6891327Abstract: An electroluminescent device (1) has a relief pattern (17) comprising overhanging sections (13) for patterning an electrode layer (11) of the device (1). In order to prevent the take up and transport of fluid, from which a functional layer (7, 9) is obtainable, along the capillary channels (23) formed by the overhanging sections (13), the relief pattern (17) comprises accompanying sections (15) which are positioned at distance of the overhanging sections (13) and between the sections (13) and the electroluminescent areas (21) comprising the functional layers (7, 9). A method of manufacturing the EL device (1) comprises depositing the functional layer or layers (7, 9) by means of a wet deposition method such as inkjet printing.Type: GrantFiled: April 24, 2002Date of Patent: May 10, 2005Assignee: Koninklijke Philips Electronics N.V.Inventors: Paulus Cornelis Duineveld, Ivo Godfried Jozef Camps, Coen Theodorus Hubertus Fransiscus Liedenbaum, Eliav Itzhak Haskal, Maria Henrica Wilhelmina Antonia Van Deurzen, Jochem Petrus Maria De Koning

Patent number: 6583584Abstract: An electroluminescent device has at least two electroluminescent elements arranged on a substrate in accordance with a desired pattern, each element comprising a first and a second electrode layer and, disposed therebetween, an electroluminescent layer obtained from a liquid layer. A partitioning relief pattern including partitioning ribs of an insulating material protruding from the substrate, forms enclosure areas for containing the liquid layer in accordance with the desired pattern. In order to prevent mixing of liquids between adjacent electroluminescent elements and to allow filling of a maximum amount of liquid in each element, the partitioning element between adjacent elements is comprised of at least two partitioning ribs with an intermediate groove in the area between the partitioning ribs. The invention also refers to a method for manufacturing of an electroluminescent device.Type: GrantFiled: April 24, 2002Date of Patent: June 24, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Paulus Cornelis Duineveld, Coen Theodorus Hubertus Fransiscus Liedenbaum, Jochem Petrus Maria De Koning, Ivo Godfried Jozef Camps
