A display device including a display panel, and a lifting part configured to move one end of the display panel in an upward or downward direction. The lifting part includes: a fixing unit fixed to the other end of the display panel a movable unit configured to move in the upward or downward direction, a motor connected to the movable unit and configured to move the movable unit in the upward or downward direction, and a panel connection block fixed to the movable unit and configured such that the one end of the display panel is fixed to the panel connection block.

Display device

Rollable display screen

A display device includes a display panel in which an image is displayed; a tape spring which is connected to the display panel to lift the display panel; a first roller on which the display panel is wound or unwound; a second roller on which the tape spring is wound or unwound; and a timing belt which rotates the second roller in the same direction as the first roller when the first roller is wound or unwound.

A display device includes a display part including a display panel for displaying an image, a roller part configured to wind or unwind the display part, and a tape spring configured to move the display part in an upward and/or downward direction in conjunction with an operation of the roller part, and the roller part includes: a motor; a tape spring drum configured to accommodate the motor and connected to the motor, the tape spring drum being configured such that one end of the tape spring is fixed to the tape spring drum, and the tape spring drum winds or unwinds the tape spring; a tape spring casing configured to accommodate the tape spring drum and the tape spring; and a plurality of roll drums connected to two opposite sides of the motor.

A display device can include a display panel, a roller which guides the sliding of the display panel, a rotary shaft which passes through both ends of the roller, and an elastic member having one end connected to an inner circumferential surface of the roller and the other end connected to the rotary shaft, and the roller and the rotary shaft are rotatably connected to each other. Accordingly, according to the present disclosure, one end and the other end of the elastic member are configured to be rotatable to minimize the excessive increase of the tensile stress of the elastic member which is transmitted to the display panel and improve the reliability of the display panel.

A display device includes a display assembly including a display panel and a back cover configured to support a rear surface of the display panel, a roller configured to wind or unwind the display assembly, a drive assembly configured to move the roller in an amount corresponding to a winding amount or an unwinding amount of the display assembly about the roller, and a housing configured to accommodate the display assembly, the roller and the drive assembly, the housing having an opening through which the display assembly moves in and out of the housing in response to rotation of the roller.

A display device according to an embodiment of the present disclosure includes a display panel, a roller on which the display panel is wound or unwound, and a lifting unit configured to move the display panel in a vertical direction, wherein the lifting unit includes a plurality of chain units configured to be coupled when ascending and separated from each other when descending, a first power transmission unit configured to lift the plurality of chain units, and a second power transmission unit configured to couple or separate the plurality of chain units by switching movement directions of the plurality of chain units, so that durability and wobbling of the display device can be improved.

A display device includes a display panel, a roller around which the display panel is wound or unwound, a housing unit which accommodates the display panel and the roller, a head bar connected to one end of the display panel, and a support plate which supports a rear surface of the display panel, has one side fixed to the head bar, and the other side fixed to the housing unit, and forms a mesh pattern.

A display device includes a display panel, a roller configured to wind or unwind the display panel, a flexible cable configured to transmit an electrical signal to the display panel and including an extension part to be wound around the end of the roller.

Provided is a display device. The display device includes a display panel including a plurality of pixels. The display device further includes a roller to which the display panel is wound or unwound. The display device further includes a lifting unit configured to move the display panel in a vertical direction. The lifting unit lifting unit includes a plurality of unit blocks and a plate to which the plurality of unit blocks is fixed. Therefore, the structure of the lifting unit is simplified to improve the durability and the rocking.

A display apparatus includes: a display panel configured to display an image, a vibration plate on a first surface of the display panel, a first structure on a second surface of the vibration plate, the first structure being configured to support the display panel, a first vibration-generating device configured to vibrate the vibration plate, and a separation part connected to the vibration plate and configured to separate a first space, facing a first surface opposite to the second surface of the vibration plate, from a second space facing the second surface of the vibration plate.

Display apparatus

A backlight unit, a liquid crystal display (LCD) device, and an electronic device including the same are provided. The backlight unit includes a light guide member having a light receiving edge provided on an outer wall, and a hole spaced apart from light receiving edge; a light source configured to provide light to the light receiving edge; and a reflective member on an inner wall of the hole of the light guide member.

Backlight unit, liquid crystal display device, and electronic device including the same

A light guide plate includes a main body having a light receiving edge and an opposite side, the opposite side being opposite from the light receiving edge; at least one variant portion having a protruded portion that protrudes from the main body from the opposite side, the at least one variant portion defining a hole vertically passing through the main body; and an optical pattern provided in the at least one variant portion.
