Abstract: A display apparatus includes a display panel including a plurality of pixels and configured to display an image; a housing module including a roller therein such that the display panel is configured to be wound on the roller to be housed in the housing module or unwound from the roller to extend from the housing module; a rolling module including a structure connected to the display panel and configured to wind or unwind the display panel according to a folding or unfolding of the structure; and a vibration device on the structure, the vibration device configured to vibrate the display panel in an unwound state.

Abstract: A rollable display device is disclosed. The rollable display device includes a display panel, a driving unit including a motion converting unit configured to linearly move in a width direction of the display panel in conjunction with a rotational motion of a motor, a lifting unit connected to one end of the display panel and the motion converting unit, and configured to move up and down the display panel in a longitudinal direction of the display panel in conjunction with a linear motion of the motion converting unit, and a panel roller unit connected to other end of the display panel, and configured to roll and unroll the display panel along a periphery of the panel roller unit in conjunction with moving up and down of the display panel.

Abstract: A rollable display includes a flexible display panel that can be rolled up and down, a back cover that rolls up and down along with the flexible display panel, with one edge fixed to one edge of the flexible display panel, and a flexible magnet fixed to either the flexible display panel or the back cover and interposed between the flexible display panel and the back cover.

Abstract: A rollable display comprises a flexible display panel; at least one BRC member having one end coupled with an edge of the flexible display panel; a roller assembly having a roller coupled with another end of the BRC member and a motor for rotating the roller, the roller assembly being ascended while rolling the BRC member onto the roller when the motor is rotated in a first direction, and being descending while unrolling the BRC member from the roller when the motor is rotated in a second direction opposite to the first direction; and a panel guide part connected to the roller assembly and moved along with the roller assembly; wherein the flexible display panel is rolled onto the panel guide part when the roller assembly and the panel guide part ascend, and is unrolled from the panel guide part when the roller assembly and the panel guide part descend.

Abstract: A method of fabricating backlight unit is disclosed. The backlight unit method of fabricating backlight unit includes, preparing a base member having a predetermined thickness, applying ultraviolet curing resin on a surface of the base member, transferring prism patterns to the ultraviolet curing resin using a flexible mold having engraved patterns corresponding to the prism patterns, and curing the prism patterns before the prism patterns are separated from the engraved patterns of the flexible mold.

Abstract: A backlight unit is disclosed. The backlight unit includes a light source unit generating light, a beam profile changer at the side of the light source unit, a reflective plate under the beam profile changer, and an optical film positioned on the beam profile changer and the reflective plate. The beam profile changer includes an incident surface facing the light source unit and an emitting surface positioned in a direction parallel to the incident surface. The reflective plate includes a first reflective surface having a first reflective area and a second reflective surface having a second reflective area. The second reflective surface is inclined from an end of the first reflective surface to an upward direction.
