WHITE REFLECTIVE FILM FOR EDGE-LIGHT TYPE BACKLIGHT, AND LIQUID CRYSTAL DISPLAY BACKLIGHT USING SAME
Publication number: 20170184777Abstract: A white reflective film for an edge light backlight improves the luminance and unevenness therein, voids uneven close contact with, and scraping of, the light guide plate, and minimizes the crushing of convexes formed on at least one side, even in cases where the reflective film is laid directly over a corrugated chassis designed to house circuitry or the reflective film is used in combination with LEDs. The film satisfies (i) to (iii): (i) a stiffness of 2 to 10 mN·m; (ii) convexes have been formed on at least one face (A), and their maximum height is 5 to 60 ?m; (iii) the convexes contain an aromatic polyester.Type: ApplicationFiled: March 9, 2017Publication date: June 29, 2017Inventors: Yoshihiko Sakaguchi, Yuji Kawata, Motoyuki Suzuki -

Patent number: 8557370Abstract: A white film including polymer film wherein both the thermal shrinkage rate in the longitudinal direction and that in the transverse direction of the film are not less than ?0.2% and not more than 0.5% at 90° C., and a backlight for liquid crystal displays using such a white film. Since the white film hardly suffers from undulation or rise in its end portions, it is most suitable as a reflection film for backlights of liquid crystal displays. Since a backlight for liquid crystal displays using this white film can be used for a long time, it is applicable to liquid crystal displays of various electrical/electronic devices.Type: GrantFiled: October 13, 2011Date of Patent: October 15, 2013Assignee: Toray Industries, Inc.Inventors: Tomoko Kanaya, Tadami Matsuyama, Yoshihiko Sakaguchi, Osamu Watanabe

Publication number: 20110126144Abstract: An equipment management apparatus is configured to provide a management screen in order to manage a plurality of equipments scattered within a superordinate space including a plurality of subordinate spaces. The equipment management apparatus includes a first display control section and a condition determination section. The first display control section displays a superordinate object and a plurality of subordinate objects in a tree structure on the management screen. The superordinate object corresponds to the superordinate space, and the subordinate objects correspond to the subordinate spaces. The condition determination section determines whether or not the equipments satisfy a predetermined condition.Type: ApplicationFiled: May 19, 2009Publication date: May 26, 2011Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Yoshihiko Sakaguchi, Toshiyuki Miki, Masahiro Kaneko
