Patent number: 9614191Abstract: A method of manufacturing an organic-light emitting diode (OLED) display can include providing on a substrate a first electrode associated with a first sub-pixel and a second electrode associated with a second sub-pixel, wherein a gap is formed between the first electrode and the second electrode and wherein the first electrode and the second electrode are positioned in a well having boundaries defined by a confinement structure on the substrate. The method can also include depositing in the well with the electrodes positioned therein, active OLED material to form a substantially continuous layer of active OLED material that spans the boundaries of the well such that a surface of the layer of active OLED material that faces away from the substrate has a non-planar topography. The depositing can be via inkjet printing.Type: GrantFiled: September 18, 2013Date of Patent: April 4, 2017Assignee: Kateeva, Inc.Inventor: Conor Francis Madigan

Patent number: 8298830Abstract: The present invention generally relates to polymers with lasing characteristics that allow the polymers to be useful in detecting analytes. In one aspect, the polymer, upon an interaction with an analyte, may exhibit a change in a lasing characteristic that can be determined in some fashion. For example, interaction of an analyte with the polymer may affect the ability of the polymer to reach an excited state that allows stimulated emission of photons to occur, which may be determined, thereby determining the analyte. In another aspect, the polymer, upon interaction with an analyte, may exhibit a change in stimulated emission that is at least 10 times greater with respect to a change in the spontaneous emission of the polymer upon interaction with the analyte. The polymer may be a conjugated polymer in some cases. In one set of embodiments, the polymer includes one or more hydrocarbon side chains, which may be parallel to the polymer backbone in some instances.Type: GrantFiled: June 7, 2010Date of Patent: October 30, 2012Assignee: Massachusetts Institute of TechnologyInventors: Aimee Rose, Timothy M. Swager, Zhengguo Zhu, Vladimir Bulovic, Conor Francis Madigan
