Display device

A display device includes a display panel, a plurality of flexible films electrically connected to one end of the display panel, a source printed circuit board electrically connected to the plurality of flexible films, a roller on which the display panel is wound or unwound, a control printed circuit board disposed in the roller and a wiring sheet including a first wiring line electrically connecting at least one of the plurality of source printed circuit boards and the control printed circuit board. By disposing the wiring sheet in which the first wiring and the sheet are integrated, damage of the first wiring due to repeated winding and unwinding can be minimized.

A display device may include a display panel, a first back cover disposed on a rear surface of the display panel, at least one flexible film which is electrically connected to one end of the display panel and is bent toward a rear surface of the first back cover or a front surface of the display panel, and a printed circuit board which is electrically connected to the at least one flexible film and disposed on the rear surface of the first back cover or the at least one flexible film. The printed circuit board overlaps one end of the display panel. Accordingly, one end of the display panel in which the pad area which is vulnerable to the stress is disposed and the printed circuit board are maintained to be flat, to minimize the damage of the display device.

A display device includes a display panel, a first cover supporting a rear surface of the display panel and a second cover with a first end of the second cover connected to the first cover. The display device also includes a roller to which a second end of the second cover is fixed with the roller configured to wind or unwind the display panel. The display device further includes a fastening member configured to fix the second end of the second cover to the roller. The roller includes a flat part and a curved part, and the flat part includes a first flat portion and a second flat portion that is closer to a center surface of the roller than the first flat portion. The fastening member is disposed on the second flat portion.

Disclosed herein is a display device. The display device comprises: a mid cover; a display panel disposed on the mid cover and having a plurality of pixels defined therein; a plurality of back bars disposed under the mid cover; and a roller fixed to the mid cover. The mid cover, the display panel and the plurality of back bars are wound around or unwound from the roller.

A display device includes a display panel including a display area where images are displayed, a first cover configured to support a rear surface of the display panel, a roller configured to wind or unwind the display panel and the first cover, a second cover with a first end of the second cover fixed to the roller and a second opposite end of the second cover connected to an end of the first cover, and a cover assembly connecting the first cover and the second cover, wherein a boundary of the display area overlaps the cover assembly, and the cover assembly is configured to expose the display area.

A display device includes a display panel in which a plurality of pixels is defined, a back cover disposed on a rear surface of the display panel, a roller which is connected to the back cover to wind or unwind the back cover and the display panel, and a protective sheet which is disposed on a rear surface of the back cover and has a relatively small tensile strength in a rolling direction of the roller to reduce the stress generated during rolling and improve the lateral rigidity of the display unit.

A display device includes a display panel including a display area on which a plurality of display elements is disposed and a non-display area on which one or more wires for driving the plurality of display elements are disposed. A back cover is attached to one surface of the display panel and has a plurality of openings. A roller unit winds or unwinds the back cover and the display panel, and a lifting unit moves the back cover and the display panel in a vertical direction. The plurality of openings overlaps the display panel, and each of the plurality of openings is disposed to be staggered with one or more of the openings in an adjacent row. A size of the back cover is larger than a size of the display panel.

A display device includes: a display panel and a back cover which is disposed on one surface of the display panel and has a plurality of openings in which a left edge and a right edge among a plurality of edges of the back cover are bent toward the display panel. Therefore, a display device in which the left edge and the right edge of the back cover are bent to improve a sharp edge is provided and an injury risk of the user due to the sharp edge may be avoided.

A display device includes: a display panel and a back cover which supports the display panel on a rear surface of the display panel and includes a plurality of openings and a length of a lower edge of the back cover is larger than a length of an upper edge of the back cover. Therefore, when the display device is rolled, a rolling position of the display device may be guided.

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.

Display apparatus

A disclosed display device may include a display panel including a plurality of sub-pixels, and a back cover configured to support the display panel and configured be wound or unwound along with the display panel. The display device may further include a base plate on a first surface of the back cover to support the back cover and a top cover on a second surface of the back cover opposite the first surface so that the back cover is between the base plate and the top cover. The top cover may be fixed to the back cover. The top cover may have a curved outer peripheral surface.

A display device includes: a display panel, a back cover which supports the display panel on a rear surface of the display panel; at least one flexible film which is electrically connected to one end of the display panel and is on one surface of the back cover; a printed circuit board which is electrically connected to the at least one flexible film and on one surface of the back cover; and a roller on which the display panel and the back cover are wound or unwound, the roller being configured by a first flat portion, a second flat portion, and a curved portion. When the display panel and the back cover are fully wound around the roller, the at least one flexible film corresponds to the first flat portion, and the printed circuit board corresponds to the second flat portion.

A rollable display device is disclosed. The rollable display device includes a rollable display panel, a roller configured to roll and unroll the rollable display pane, and a first printed circuit board electrically connected to the rollable display panel. The first printed circuit board comprises a curved surface having a curvature that matches a curvature of a curved surface of the roller. The first curved surface of the printed circuit board is in contact with the curved surface of the roller.

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.
