Patent number: 8384838Abstract: A liquid crystal display device is provided, capable of minimizing deterioration in display quality of a liquid crystal panel due to external force generated by connection with an external chassis such as a customer's chassis. The liquid crystal display device has, at least, a front frame, a liquid crystal panel, and a backlight unit having at least a rear frame, arranged in this order. A back fixing frame to be fixed to the front frame is provided on the back face of the liquid crystal display device, and attachment portions to be attached to an external chassis are provided in the back fixing frame. This makes it difficult for external force generated by connection with the external chassis to be transmitted to the liquid crystal panel or the backlight unit, suppresses deformation of the liquid crystal panel or reflection sheet and prevents deterioration in display quality.Type: GrantFiled: April 25, 2008Date of Patent: February 26, 2013Assignee: NLT Technologies, Ltd.Inventors: Hideaki Sugawara, Yasushi Takada

Patent number: 7852424Abstract: A film member is provided between a liquid crystal panel and the front panel of a front frame. The film member is thinner than the gap between the liquid crystal panel and the front panel. The film member is strip-shaped, one end part thereof in the width direction is attached to the front panel, and the other end part thereof is in contact with the liquid crystal panel. The film member is formed from PET, has a thickness of 25 to 100 ?m, and is black or gray in color. Four such strip-shaped film members are positioned so as to surround the opening of the front frame. A large load is thereby not placed on the liquid crystal panel, the thickness of the device as a whole in not increased, and the ingress of debris and light leakage can be prevented.Type: GrantFiled: December 27, 2005Date of Patent: December 14, 2010Assignee: NEC CorporationInventor: Hideaki Sugawara

Patent number: 7641373Abstract: Disclosed is a backlight unit which illuminates a display panel from a rear surface thereof, including at least: tubular lamps arranged in parallel to the panel; and a reflecting member which reflects light from the lamps toward the panel, wherein the reflecting member is divided into a first region opposed to an area near an electrode provided in an end portion of the lamp and a second region nearer to a middle area than the first region, the first region having a higher reflectance than the second region. In another backlight unit, a reflecting member is divided, with respect to the arrangement direction of the lamps, into an end lamp near region which is opposed to a lamp arranged in end portion and a middle region which is nearer to a middle area than the end lamp region, the end lamp region having a higher reflectance than the middle region.Type: GrantFiled: September 7, 2006Date of Patent: January 5, 2010Assignee: NEC LCD Technologies, Ltd.Inventors: Hideaki Sugawara, Hiroshi Ishida

Patent number: 7190423Abstract: A liquid crystal monitor incorporating therein a liquid crystal module having a direct backlight is configured to have receiving portions in a reflector 8 of the direct backlight that constitutes a liquid crystal module 13, in order to attach together the liquid crystal module 13 and a liquid crystal monitor member 12. The receiving portions are constituted by reflector extensions 111 that are formed by extending a bottom face of the reflector 8 toward a space between an inclined face of the reflector and an upper frame 2 of the liquid crystal module 13. Then, the liquid crystal monitor member 12 is fixed to the reflector extensions 111 by screws 407. Thus, the use of a space near the inclined face of the reflector allows a liquid crystal monitor to be thinned and reduced in its size and the width of monitor frame.Type: GrantFiled: June 17, 2003Date of Patent: March 13, 2007Assignee: NEC LCD Technologies, Ltd.Inventors: Hideaki Sugawara, Hiroshi Ishida
