  • Patent number: 12131845
    Abstract: A wiring member includes: a flat wiring member including a sheet member, and a plurality of wire-like transmission members fixed on the sheet member in a parallel state; and a protective member configured to accommodate the flat wiring member. The protective member includes a placement surface on which the sheet member is placed. The sheet member includes a disposition region in which the plurality of wire-like transmission members are disposed. The sheet member is placed on the placement surface so that at least the disposition region extends along the placement surface.

  • Patent number: 9102783
    Abstract: A strippable coating composition for floors which contains at least 50% by weight of an aqueous polyurethane resin relative to the total solid content, wherein the hydroxyl-containing compound component constituting the aqueous polyurethane resin comprises (A) a polyester polyol component prepared from 1,6-hexanediol and either an aliphatic dibasic acid and/or an aromatic dibasic acid, (B) a low-molecular alicyclic diol component, and (C) an unsaturated fatty acid ester polyol. The strippable coating composition can form a coating film that has a tear strength of 0.3N or more, a break strength of 10 MPa or more, and an elongation at break of 50% or more.

  • Publication number: 20120026215
    Abstract: A display device supplies, during a vertical blanking interval, a data signal for a gray display to each data signal line so as to cause the each data signal line to retain the data signal for the gray display. In at least one example embodiment, the data signal for the gray display has a polarity identical to a polarity of a data signal supplied immediately before the vertical blanking interval.

  • Patent number: 8094108
    Abstract: A gradation voltage adjustment section for increasing a positive gradation voltage VHX of an X-th gradation and a negative gradation voltage of the X-th gradation so that the increment corresponds to a charge pull-in amount ?V is provided in a gradation voltage generation circuit of each source driver. In at least one embodiment, a center value between the positive and negative gradation voltages is adjusted for each driver in accordance with a slant of the charge pull-in amount ?V in a direction of a gate signal line, thereby suppressing a flicker without varying a gradation characteristic. Further, a center value between the positive and negative gradation voltages is adjusted for each horizontal line or for every plural lines in a single frame in accordance with a horizontal direction deviation and a vertical direction deviation of the charge pull-in amount ?V in a transfer block, thereby suppressing a flicker without varying a gradation characteristic.

  • Publication number: 20110249216
    Abstract: A liquid crystal panel (2) is equipped with a first transparent substrate (21) on which a TFT is formed, a second transparent substrate (22), and a liquid crystal layer (23) interposed therebetween. An illumination device is disposed on the first transparent substrate side of the liquid crystal panel. When viewed along the normal direction of the primary surfaces of the first and second transparent substrates, a portion of the first transparent substrate protrudes beyond the second transparent substrate and a portion of the second transparent substrate protrudes beyond the first transparent substrate. The portion of the second transparent substrate which protrudes beyond the first transparent substrate is supported by a support part (41). Thus, it is possible to reduce display anomalies generated when pressure is applied to the display screen by a finger or the like.
