  • Patent number: 10600990
    Abstract: A display device includes a display panel and a back cover coupled and fixed to each other via a resin layer to manufacture a lightweight, thin display device having a slim bezel while increasing the drooping resistance of the display device. In addition, since the drooping resistance of the display device is increased, it is possible to reduce the thickness of the back cover, whereby it is possible to further reduce the weight of the display device. Furthermore, a through-hole is formed in a cover shield such that a portion of the upper part of an IC chip of a substrate can be inserted into the through-hole, with the result that the coupling structure of a circuit unit is improved, whereby it is possible to further reduce the thickness of the display device.

  • Publication number: 20190141843
    Abstract: Disclosed is a rollable display, which prevents slippage between a flexible display panel and a back plate attached to the flexible display panel for supporting the same. The rollable display has a feature in different patterns of the back plate for each area. In addition, the rollable display has a feature in that a display unit is foldable and non-foldable via a link unit so as not to be folded or rolled multiple times in the same direction.

  • Patent number: 9019443
    Abstract: A backlight unit adapted to prevent light leakage and damage of its internal components due to a thermal deformation is disclosed. The backlight unit includes: a bottom cover with an opened upper surface; a printed-circuit-board disposed on at least one inner side surface of the bottom cover; a plurality of LEDs loaded on the printed-circuit-board; and a plurality of slits formed on at least one edge of the bottom cover opposite to the printed-circuit-board and configured to reduce thermal deformation of the bottom cover.
