  • Publication number: 20140268595
    Abstract: A flexible display device includes a flexible display panel, a flexible printed circuit board extending from the display panel, an integrated circuit chip that is mounted on at least one surface of the flexible printed circuit board and is configured to drive the display panel, and a protection member attached to a rear surface of the display panel. When the flexible printed circuit board is flexed to be partially positioned on the rear surface of the display panel, the protection member is positioned between the display panel and the integrated circuit chip. The flexible display device prevents the integrated circuit chip stacked with the display panel from making direct contact with the display panel using the protection member. Thus, even if the display device is deformed into, for example, a flexed or rolled state, it is possible to prevent the display panel from being damaged.

  • Patent number: 8835057
    Abstract: The present invention relates to an anode for a secondary battery, comprising: a spiral anode having at least two anode wires which are parallel to each other and spirally twisted, each of the anode wires having an anode active material layer coated on the surface of a wire-type current collector; and a conductive layer formed to surround the spiral anode. The anode active material layer of the spirally-twisted has a thin thickness as compared with a single strand of an anode having the same anode active material. Therefore, Li ions can be easily diffused to enhance battery performance.
