Publication number: 20100289985Abstract: An illumination unit of the present invention includes: a light guide plate; a point light source for illuminating at least one side surface of the light guide plate; and an anisotropic light diffuser provided between the light guide plate and the point light source for diffusing light emitted from the point light source. The anisotropic light diffuser has anisotropy by which a degree of diffusion differs depending on directions. The anisotropic light diffuser is an anisotropic light diffusion sheet with a particulate dispersion phase defined in an anisotropic light diffusion layer thereof.Type: ApplicationFiled: May 3, 2010Publication date: November 18, 2010Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Yoshihide NISHIDA, Yuji TSUCHIYAMA

Patent number: 7641377Abstract: An object of the present invention is to provide a display device with high withstand mechanical-shock property, and improve quality of the product by controlling occurrence of display defects such as uneven luminance. The display device includes a light guiding plate 1 being provided a light source 5 on an upright surface 1b, optical sheets 2 being provided at a side of light emitting surface of said light guiding plate, a light source supporting member being provided for supporting said light source and a frame 4 having a protrusion 4a for supporting said light guiding plate from the upright surface 1b of said light guiding plate 1. Furthermore, a projection is formed at optical sheets, and cut-out, which includes the projection therebetween, is provided at the frame 4.Type: GrantFiled: January 11, 2005Date of Patent: January 5, 2010Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yoshihide Nishida, Yuji Tsuchiyama, Masayuki Kawano

Patent number: 6806921Abstract: A liquid crystal display device including a liquid crystal display panel, an illumination unit including a light-conducting plate having a protrusion protruded from a side surface of the light-conducting plate, and a housing having a bottom plate and a casing provided onto a bottom plate peripheral area for holding the light-conducting plate. A depression portion is formed to the casing of the housing. An inside of the bottom plate peripheral area is processed from roots of the end surfaces along the end surfaces so that a first slit which continues to the end surfaces is formed. The casing in a position separated from the end surfaces with a predetermined interval and an inside of the bottom plate peripheral area in this position are processed so that a second slit is formed.Type: GrantFiled: August 29, 2002Date of Patent: October 19, 2004Assignee: Advanced Display Inc.Inventors: Yoshihide Nishida, Hiroyuki Nakano, Yuji Obuchi

Patent number: 6784951Abstract: A display device comprising a front frame having an annular picture frame and having a pair of side faces and a pair of end faces provided in outer circumferential sides of the picture frame, a mold frame sandwiched by the pair of side faces and the pair of end faces, and a display panel arranged between the front frame and the mold frame. Stopper pieces for alignment of the display panel are formed in the side faces and the end faces. A display device in which the picture frame of the front frame can be narrowed is obtainable.Type: GrantFiled: August 6, 2001Date of Patent: August 31, 2004Assignee: Advanced Display Inc.Inventors: Takuya Kuroki, Yoshihide Nishida

Patent number: 6608748Abstract: In order to prevent the display quality of a display device from deteriorating due to an external stress, a liquid crystal panel for displaying images and characters, and an illuminator for projecting light from the back of the liquid crystal panel are supported by a mold frame (1) in FIG. 3 and a front frame fixed to the mold frame (1). The mold frame (1) is formed with mounting holes for attaching the liquid crystal panel to an external device such as personal computer, and is at its corners with cutouts (20) for absorbing the external stresses which are propagated through the mounting holes in a state where the display device is attached to the external device.Type: GrantFiled: August 15, 2000Date of Patent: August 19, 2003Assignee: Kabushiki Kaisha Advanced DisplayInventors: Ikuo Ogo, Yoshihide Nishida, Masayuki Kawano, Hisashi Ohta, Kazutoshi Shimojo

Patent number: 6533428Abstract: A thin flat-surface type display device having a transmissive display panel is provided, which is capable of securing a space of an essential electric circuit for driving the display device without deteriorating an optical performance (luminance and uniformity thereof) of a surface light source device of an edge light system employed as a backlight. A light guide plate forming the surface light source device of the edge light system has a flat light emitting surface, and a back surface arranged so as to include (1) an inclined flat surface portion where a thickness of the light guide plate decreases linearly from a light-incident portion on which light emitted from a linear light source is incident toward a light-anti-incident portion, and (2) a parallel flat surface portion which is parallel with the light emitting surface in the vicinity of the light-anti-incident portion.Type: GrantFiled: January 16, 2001Date of Patent: March 18, 2003Assignees: Kabushiki Kaisha Advanced Display, Mitsubishi Denki Kabushiki KaishaInventors: Ikuo Ogo, Shigeru Yachi, Yoshihide Nishida, Atsushi Ito, Toshiyuki Yoneda
