Abstract

A slidable display device includes: a display panel; and a support member supporting the display panel. The support member includes a first portion maintaining a form and a second portion adjacent to the first portion and being transformable, the second portion includes a plurality of bars, and each of the plurality of bars includes an edge side including a first side, a second side connected to the first side and being inclined from the first side, a third side including two sides forming a step, a fourth side connecting between the two sides of the third side, a fifth side including two sides facing the third side and forming a step, and a sixth side connecting between the two sides of the fifth side.

First claim

What is claimed is:

1. A slidable display device comprising:
a display panel; and
a support member supporting the display panel, wherein
the support member includes:
a first portion maintaining a form, and
a second portion adjacent to the first portion and transformable,

the second portion of the support member includes a plurality of bars, and
each of the plurality of bars includes an edge side including:
a first side;
a second side connected to the first side and being inclined from the first side;
a third side including two sides forming a step;
a fourth side connecting between the two sides of the third side;
a fifth side including two sides facing the third side and forming a step; and
a sixth side connecting between the two sides of the fifth side.

2. The slidable display device of claim 1 , wherein the first side of each bar faces the display panel.

3. The slidable display device of claim 2 , wherein
the plurality of bars include a first bar and a second bar that are adjacent to each other and engaged to each other, and
the third side and the fourth side of the first bar face the fifth side and the sixth side of the second bar.

4. The slidable display device of claim 3 , wherein
the third side and the fourth side are alternately disposed in a linear shape or a curved shape, and
the fifth side and the sixth side are alternately disposed in a linear shape or a curved shape.

5. The slidable display device of claim 3 , wherein
the third side and the fourth side form a concave shape, and
the fifth side and the sixth side form a convex shape.

6. The slidable display device of claim 1 , wherein
the slidable display device includes:
a curved portion of which a position is changeable according to a sliding operation, and
a first non-curved portion connected to the curved portion, and

the first non-curved portion includes the first portion of the support member.

7. The slidable display device of claim 6 , wherein the curved portion includes the second portion of the support member.

8. The slidable display device of claim 7 , wherein, in case that a slide-out operation is performed, a position of the curved portion is moved and the first non-curved portion extends.

9. The slidable display device of claim 8 , further comprising:
a second non-curved portion connected to the curved portion in case that a slide-in operation is performed, wherein
the second non-curved portion faces the first non-curved portion, and
the second non-curved portion includes the first portion of the support member.

10. The slidable display device of claim 6 , wherein
a gap between neighboring bars disposed on the curved portion is less than a gap between neighboring bars disposed on the first non-curved portion.

11. The slidable display device of claim 6 , wherein
the plurality of bars include:
a first bar and a second bar adjacent to each other and disposed on the curved portion and
a third bar and a fourth bar adjacent to each other and disposed the first non-curved portion, and

a distance between the first side of the first bar and the first side of the second bar is substantially equal to a distance between the first side of the third bar and the first side of the fourth bar.

12. The slidable display device of claim 1 , further comprising
a support plate disposed between the display panel and the support member,
wherein the support plate includes a planar plate portion overlapping the first portion of the support member and a flexible portion overlapping the second portion of the support member.

13. The slidable display device of claim 12 , wherein the flexible portion of the support plate includes a plurality of pattern portions from which at least part of the support plate is removed.

14. The slidable display device of claim 13 , wherein
the first side does not overlap the plurality of pattern portions, and
the second side overlaps the plurality of pattern portions.

15. The slidable display device of claim 1 , further comprising:
a pair of guide portions disposed on a lateral side on which respective end portions of the bars are disposed,
wherein the guide portion includes a guide rail that guides movement of the bars.

16. The slidable display device of claim 15 , wherein
the plurality of bars further include a combining portion disposed on respective end portions, and
the combining portion includes a first fixing portion and a second fixing portion disposed on respective sides of the guide rail.

17. A slidable display device comprising:
a display panel; and
a support member supporting the display panel, wherein
the support member includes:
a first portion maintaining a form, and
a second portion adjacent to the first portion and transformable,

the second portion includes a plurality of bars,
the display panel and the support member include a curved portion of which a position is changeable according to a sliding operation and a first non-curved portion connected to the curved portion,
the first non-curved portion includes the first portion of the support member, and
a gap between neighboring bars of the plurality of bars disposed on the curved portion is less than a gap between neighboring bars of the plurality of bars disposed on the first non-curved portion.

18. The slidable display device of claim 17 , wherein
the curved portion includes the second portion of the support member, and
the position of the curved portion is moved and the first non-curved portion extends in case that a slide-out operation is performed.

19. The slidable display device of claim 17 , wherein
each of the plurality of bars respectively includes a first side facing the display panel,
the plurality of bars include:
a first bar and a second bar adjacent to each other and disposed on the curved portion, and
a third bar and a fourth bar adjacent to each other and disposed the first non-curved portion, and

a distance between the first side of the first bar and the first side of the second bar is substantially equal to a distance between the first side of the third bar and the first side of the fourth bar.

20. A slidable display device comprising:
a display panel;
a support member supporting the display panel; and
a support plate disposed between the display panel and the support member,
wherein the support member includes:
a first portion maintaining a shape, and
a second portion disposed near the first portion and being transformable,

the second portion includes a plurality of bars,
the display panel and the support member include a curved portion of which a position is changeable according to a sliding operation, and a first non-curved portion connected to the curved portion,
each of the plurality of bars includes an edge side including:
a first side contacting a support plate, and
a second side bent on the first side, wherein

the second side of the bar disposed on the first non-curved portion is spaced from the support plate by a first gap, and
the second side of the bar disposed on the curved portion is spaced from the support plate by a second gap that is less than the first gap or contacts the support plate.
