Publication number: 20100233931Abstract: A method of manufacturing a light emitting device is provided in which satisfactory image display can be performed by the investigation and repair of short circuits in defect portions of light emitting elements. A backward direction electric current flows in the defect portions if a reverse bias voltage is applied to the light emitting elements having the defect portions. Emission of light which occurred from the backward direction electric current flow is measured by using an emission microscope, specifying the position of the defect portions, and short circuit locations can be repaired by irradiating a laser to the defect portions, turning them into insulators.Type: ApplicationFiled: May 7, 2010Publication date: September 16, 2010Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Hirokazu Yamagata, Yoshimi Adachi, Noriko Shibata

Patent number: 7701133Abstract: The present invention provides an organic electroluminescent display device and a method of repairing a defective pixel of an organic electroluminescent display device which can realize the repairing a defective pixel to a light emitting pixel by electrically separating a leak portion which generates a defective pixel. To be more specific, a peeling suppression layer is formed between an anode and an organic light emitting layer formed on a main substrate, and a cavity is formed between the main substrate and the peeling suppression layer due to the evaporation generated by an absorption of laser beams thus electrically separating a defective portion so as to repair a black-dot defective pixel to form a light emitting pixel.Type: GrantFiled: March 21, 2006Date of Patent: April 20, 2010Assignee: Hitachi Displays, Ltd.Inventors: Kenta Kajiyama, Toshihiro Sato, Naoki Tokuda

Patent number: 7258586Abstract: When any of pixels is not lit in an organic EL display having an organic EL layer between a first electrode and a second electrode, an organic layer of the pixel is observed. If the organic layer of the pixel contains foreign matter, the second electrode is separated into a region in contact with the foreign matter and a region not in contact with both the contact region and the foreign matter. Thus, not-lit display regions are reduced as less as possible, making it possible to manufacture an organic EL display excellent in display performance.Type: GrantFiled: June 29, 2004Date of Patent: August 21, 2007Assignee: Hitachi Displays, Ltd.Inventors: Takuo Tamura, Mikio Hongo, Masaaki Okunaka, Shinichi Kato, Eiji Matsuzaki, Masato Ito, Masatomo Terakado

Patent number: 7086919Abstract: A detection and repair system includes an optical microscope, an image-retrieving device, an emission detector, a data controller, and a laser beam generator. When detecting the location of a defect, the system charges a detected region of an organic electroluminescent device with a negative bias or low forward bias before the device is lighted on. Then, the emission detector detects the locations of defects, which generate emission such as photons, thermal or IR emission, in an enlarged image. The laser beam generator generates a laser beam, which is used to isolate one of the defects. Furthermore, this invention also discloses a method for detecting and repairing an organic electroluminescent device.Type: GrantFiled: May 21, 2003Date of Patent: August 8, 2006Assignee: RiTdisplay CorporationInventors: Meng-Chieh Liao, Jiun-Haw Lee, Chi-Chung Chen
