Patent number: 8405308Abstract: The strength of the whole OLED is increased by proposing a new method of fixing OLED panels. To address the problem, an OLED element is formed on a substrate, and a sealing substrate of a structure by which the substrate is sealed is fixed to a lower metallic frame via an elastic sheet. Silicon resin is preferably used as the sheet, and use of a sheet having a heat diffusion function based on radiation is more desirable.Type: GrantFiled: June 21, 2011Date of Patent: March 26, 2013Assignees: Hitachi Displays, Ltd, Panasonic Liquid Crystal Display Co., Ltd.Inventors: Noriharu Matsudate, Hironori Toyoda

Patent number: 8404125Abstract: In a metal processing method, a photoresist liquid is applied to both surfaces of a metal plate (210) to form photoresist films (220, 230), respectively (Step S102). Subsequently, the photoresist films (220, 230) are exposed and developed so that the photoresist films (220, 230) is removed while leaving the photoresist films (220, 230) corresponding to portions in which a hole is to be formed (Step S103). Next, metal thin films (240, 250) are formed on both the surfaces of the metal plate (210), respectively, on which the photoresist films (220, 230) are formed (Step S104). Subsequently, the photoresist films (220, 230) are removed, and metal thin films (245, 255) are also removed, which are formed on the photoresist films (220, 230), respectively (Step S105). Finally, the metal plate (210) is immersed in an etchant to be etched, to thereby form a high-precision hole in the metal plate (210) (Step S106).Type: GrantFiled: July 27, 2010Date of Patent: March 26, 2013Assignees: Hitachi Displays, Ltd., Canon Kabushiki KaishaInventors: Noriharu Matsudate, Takeshi Ookawara

Patent number: 8053976Abstract: The present invention aims at the suppression of chromaticity irregularities and brightness irregularities by reflecting a result of an analysis of film forming misalignment of an organic EL layer. For this end, a drive circuit chip 6 is mounted on a lower side of a display panel 4, and a terminal portion 7 for connection with an external device (a host device) is mounted on an end edge of the lower side of a display panel 4. Film forming misalignment vectors (indicated by arrows) of sub pixels at an arbitrary point in a display region 5 fall within a first quadrant and an angle made between the vectors falls within 90°.Type: GrantFiled: July 11, 2008Date of Patent: November 8, 2011Assignee: Hitachi Displays, Ltd.Inventors: Noriharu Matsudate, Takeshi Ookawara

Patent number: 7915814Abstract: A top-emission-type organic EL display device which exhibits uniform screen brightness is realized by preventing a voltage drop of an upper electrode formed of a transparent conductive film. Pixels each of which is sandwiched between an upper electrode and a lower electrode are arranged in a matrix array to form a display region. An auxiliary electrode extends in the lateral direction between the pixels and the pixels for preventing a voltage drop of the upper electrode. A current supply line which supplies an electric current to the upper electrode and the auxiliary electrodes are made conductive with each other by forming a through hole in an insulation layer. To ensure reliability of connection at the through hole, a contact electrode made of metal which overlaps with the auxiliary electrode is formed on the through hole by vapor deposition.Type: GrantFiled: October 10, 2008Date of Patent: March 29, 2011Assignee: Hitachi Displays, Ltd.Inventors: Noriharu Matsudate, Takeshi Ookawara
