Patent number: 9882170Abstract: The invention provides an organic light-emitting device (OLED) comprising: a transparent substrate; a first, transparent electrode layer arranged on said substrate; one or more organic light-active layers arranged on said first electrode layer; a second electrode layer arranged on said one or more organic light-active layers; and a discontinuous layer comprising discrete, randomly distributed nanometer-sized domains of a low refractive index material, arranged between said first electrode layer and said one or more organic light-active layers. The discontinuous layer of discrete, randomly distributed nano-sized domains increases the light extraction efficiency of the OLED.Type: GrantFiled: May 23, 2012Date of Patent: January 30, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jan Frank Strömer, Marcus Antonius Verschuuren

Patent number: 9748486Abstract: The invention relates to an organic light-emitting device (OLED) comprising at least: a first electrode; a second electrode; an organic light emissive layer arranged between said first electrode and said second electrode; and an organic charge transport layer arranged between said first electrode and said emissive layer, wherein i) the charge transport layer is patterned or provided with a periodic surface structure on a surface of the charge transport layer facing the emissive layer, and/or ii) an alignment layer which allows for charge transport to the emissive layer is provided between said charge transport layer and said emissive layer, which alignment layer promotes alignment of the optical dipoles of molecules of said light emissive layer towards a common preferred direction of the molecular axes. The use of the patterned or structured charge transport layer and/or the alignment layer provides improved light out coupling from the OLED layer stack, i.e. increased external quantum efficiency.Type: GrantFiled: December 3, 2015Date of Patent: August 29, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jan Frank Strömer, Marcus Antonius Verschuuren, Dagobert Michel De Leeuw, Thomas Nicolaas Maria Bernards

Publication number: 20120069599Abstract: The invention relates to a luminous window which can function both as a broad area light source and as a transparent window. The broad area light source is achieved by coupling light into a plate-shaped light guide, e.g. via the edges of the light guide, and extracting light from the light guide using geometric protrusions or diffraction gratings into a scattering layer which outputs the broad area light. The transparent window is achieved by switching the scattering layer into a non-scattering state, and possibly switching off the light source, so that light can propagate freely through the light guide and the scattering layer.Type: ApplicationFiled: May 18, 2010Publication date: March 22, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Hugo Johan Cornelissen, Gerrit Oversluizen, Jan Frank Strömer

Patent number: 8059247Abstract: A liquid crystal display device has pixels, and each pixel has a lower substrate and an upper substrate with a liquid crystal material in between. The each pixel also has an electrode structure between the lower substrate and the upper substrate. The electrode structure has electrodes, and each electrode has a polygon-shaped electrode surface and a plurality of electrode edges. The electrodes are arranged such that if an electrode edge is facing an electrode edge of an adjacent electrode then the electrode edge and the electrode edge of the adjacent electrode define a distance which is substantially constant along the entire electrode edge.Type: GrantFiled: December 31, 2008Date of Patent: November 15, 2011Assignee: Chimei Innolux CorporationInventors: Jan Frank Strömer, Nathalie Magali Danielle Dessaud
