  • Patent number: 10401559
    Abstract: A display device includes: a display panel; a lower frame including a bottom portion and side portions; a light source unit extending along a first side portion of the lower frame; a light guide plate including a light opposing surface opposing a light incident surface in a first direction; a first auxiliary frame in the lower frame to restrict movement of the light incident surface in the first direction; a second auxiliary frame fixable to the bottom portion of the lower frame to restrict movement of the light opposing surface in the first direction; and a coupling member with which the second auxiliary frame is fixed to the lower frame. The second auxiliary frame includes a through hole through which the coupling member is extendable, and a width of a head portion of the coupling member is larger than a width of the through hole.

  • Patent number: 10197719
    Abstract: A display device includes a display panel curved with respect to a plane defined by a first direction and a second direction crossing the first direction and about a first reference axis substantially parallel to the first direction, a light guide plate disposed under the display panel and including a first surface facing the display panel and a second surface facing the display panel such that the first surface is disposed between the second surface and the display panel, a light source which provides a light to the light guide plate, and a bottom chassis which accommodates the light guide plate and the light source. The first surface is curved with respect to the plane about a second reference axis substantially parallel to the first direction, and the second surface is substantially parallel to the plane.

  • Patent number: 10078174
    Abstract: A light guide unit includes: a light guide plate curved about a center of curvature, and including a first outer circumferential surface and a first inner circumferential surface disposed closer to the center of curvature than the first outer circumferential surface; and a restoring force-offset layer coupled to at least one of the first outer circumferential surface and the first inner circumferential surface. The light guide plate includes a first material having a first thermal expansion coefficient, and the restoring force-offset layer includes a material having a thermal expansion coefficient different from the first thermal expansion coefficient to offset a restoring force of the light guide plate.

  • Publication number: 20180039012
    Abstract: A display device includes a display module, a light guide plate, a light source disposed at a side of the light guide plate in a first direction, the light source including light source units arranged in a second direction, and a condensing sheet including reverse prisms. The display module includes first and second polarizing plates facing each other, a display unit including a liquid crystal layer, and a light-conversion structure. In a plan view, the light source units include first and second light source units, which are parallel to third and fourth directions, respectively. The third and fourth directions are at angles of +45° and ?45° to the first direction. Each reverse prism includes a base surface that is parallel to the plane and includes two sides parallel to the third and fourth directions, respectively.
