  • Patent number: 9817160
    Abstract: To obtain a white reflective film that is hard to warp and can ameliorate unevenness in the luminance even when used in such a manner as to be superimposed on a chassis having convex and concave portions for placing circuits and the like or used with an LED, and can prevent uneven close contact with a light guide plate and damage of the light guide plate, the white reflective film for edge-lit backlight is made to meets the requirements (i) to (iii): (i) the stiffness is 2 to 10 mN·m; (ii) convex portions are formed on at least one surface (A) and the maximum height of the convex portion is 15 to 60 ?m; and (iii) the cushion rate at the side of a surface (B) opposite to the surface (A) is 12% or more.

  • Publication number: 20170184777
    Abstract: 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.

  • Patent number: 9046638
    Abstract: A white reflection film includes a coating layer including spherical particles on at least one surface of a white film, wherein, when particle diameters of the spherical particles are R and a thickness of the coating layer is H, an average number of the particles satisfying R>H in 100H square in a surface area of the coating layer is at least 10. The white film, which is capable of contributing to the improvement of luminance of a backlight being used in the backlight, can be provided.

  • Patent number: 8557370
    Abstract: 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.

  • Publication number: 20110126144
    Abstract: 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.
