Abstract
A flexible display device includes a plurality of back bars coupled to the rear surface of a display panel, and a spacing member disposed up to a boundary between a non-display area and a display area such that the display panel can be prevented from being scratched and damaged by friction during the rolling of the display panel. According to the aspects disclosed herein, in a flexible display device capable of implementing a rollable display or a foldable display, when rolling a display panel, it is possible to prevent the display panel from being scratched or damaged.
Claims23
A flexible display device comprising:
- a display panel;
- a cylindrical roller having an outer peripheral surface on which the display panel is rolled and unrolled;
- a connection member having a first end attached to the outer peripheral surface of the cylindrical roller and a second end connected to an end of the display panel;
- a plurality of back bars coupled to rear surfaces of the display panel and the connection member and disposed in a horizontal direction with respect to a longer side of the display panel;
- and
- a spacing member coupled to a rear surface of the one end of the connection member and disposed from each of both side ends of the connection member to a boundary between a non-display area and a display area of the display panel.
A flexible display device comprising:
- a display panel;
- a cylindrical roller having an outer peripheral surface on which the display panel is rolled and unrolled;
- a connection member having a first end fixed to the outer peripheral surface of the cylindrical roller and a second end connected to an end of the display panel;
- and
- a plurality of back bars coupled to rear surfaces of the display panel and the connection member and disposed in a horizontal direction with respect to a longer side of the display panel,
- wherein the plurality of back bars adjacent to the first end of the connection member has a height sequentially reduced toward the first end of connection member.
A flexible display device comprising:
- a display panel;
- a cylindrical roller having an outer peripheral surface, around which the display panel is wound;
- a connection member having a first end fixed to the outer peripheral surface of the cylindrical roller and a second end connected to the display panel;
- a plurality of back bars coupled to rear surfaces of the display panel and the connection member and disposed in an extending direction of the cylindrical roller;
- and
- a fixing member configured to fix at least two adjacent back bars disposed on the display panel and the connection member with respect to a connection portion where the display panel and the connection member are connected to each other, so as to prevent the connection portion from protruding to outside when the connection member and the display panel are wound around the outer peripheral surface of the cylindrical roller.
A flexible display device comprising:
- a display panel;
- a cylindrical roller having an outer peripheral surface, around which the display panel is wound;
- a connection member having a first end fixed to the outer peripheral surface of the cylindrical roller and a second end connected to the display panel;
- a plurality of back bars coupled to rear surfaces of the display panel and the connection member and disposed in an extending direction of the cylindrical roller;
- and
- a wide back bar having first and second ends with respect to a connection portion where the display panel and the connection member are connected to each other, and disposed in the extending direction of the cylindrical roller.
