Patent number: 9046628Abstract: A method of manufacturing a shaped polymer device comprises forming a planar polymer layer over a substrate which has a lower coefficient of thermal expansion than the polymer layer; and shaping the polymer layer using a laser ablation process. This method uses a substrate with low thermal expansion to limit the expansion of the attached polymer layer when it is being shaped by a laser ablation process. In addition there is provided a lens structure for an *autostereoscopic display device comprising a substantially planar glass substrate and a polymer layer defining a lenticular arrangement provided over the glass substrate.Type: GrantFiled: February 29, 2012Date of Patent: June 2, 2015Assignee: Koninklijke Philips N.V.Inventors: Hans Zuidema, Raymond Gijsbertus Anthonius Van Agthoven, Ivar Jacco Boerefijn, Henricus Joseph Cornelus Kuijpers

Patent number: 8207055Abstract: A method for generating an electrode layer pattern in an organic functional device (101; 201) comprising a first transparent electrode layer (103; 203), a second electrode layer (104; 204) and an organic functional layer (102; 202) sandwiched between said first and second electrode layers (103, 104; 203, 204). The method comprises the steps of arranging (601) a laser (704; 804) to irradiate said organic functional device (701; 801) through said first transparent electrode layer (103; 203), selecting (602) a set of laser parameters in order to enable said laser (704; 804) to locally modify an electric conductivity of said second electrode layer (104; 204), and locally modifying, by said laser (704; 804) in accordance with said set of laser parameters, the electric conductivity of said second electrode layer (104; 204), thereby generating said electrode layer pattern.Type: GrantFiled: June 27, 2006Date of Patent: June 26, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Michael Büchel, Ivar Jacco Boerefijn, Edward Willem Albert Young, Adrianus Sempel

Patent number: 7982211Abstract: A device comprising a first transparent and electrically conductive layer (102), a second electrically conductive layer (104), and a functional layer (103) comprising at least one organic layer, sandwiched between said first and second conductive layers and to form a functional organic stack. At least one via (110) is arranged to electrically interconnect said first layer (102) and at least one segment (112) of said second layer (104), the segment being electrically insulated from the reminder of the second layer. The present invention makes it possible to uniformly supply the first transparent layer with electrical power. The vias and segments are preferably formed by laser applied through the transparent conductive layer.Type: GrantFiled: June 26, 2006Date of Patent: July 19, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Michael Buchel, Adrianus Sempel, Ivar Jacco Boerefijn, Edward Willem Albert Young
