Abstract

An electronic device includes a display panel having non-folding regions arranged along a first direction and a folding region disposed between the non-folding regions. The folding region is foldable along a virtual folding axis extending along a second direction crossing the first direction. The electronic device further includes a support plate disposed on a lower portion of the display panel and having first support lines extending in the first direction, and second support lines extending in the second direction and crossing the first support lines. In the non-folding regions, the first support lines and the second support lines cross each other to define first openings, and in the folding region, the first support lines and the second support lines cross each other to define second openings. An area of each of the first openings is different from an area of each of the second openings.

Claims (35)

1. An electronic device, comprising:

a display panel comprising a plurality of non-folding regions arranged along a first direction, and a folding region disposed between the non-folding regions,

wherein the folding region is foldable along a virtual folding axis extending along a second direction crossing the first direction; and

a support plate disposed on a lower portion of the display panel, and comprising a plurality of first support lines extending in the first direction and a plurality of second support lines extending in the second direction and crossing the first support lines, wherein

in the non-folding regions, the first support lines and the second support lines define a plurality of first opening by crossing each other,

in the folding region, the first support lines and the second support lines define a plurality of second openings by crossing each other, and

an area of each of the first openings is different from an area of each of the second openings.

2. The electronic device of claim 1 , wherein among the second support lines disposed in the folding region, a distance in the first direction between adjacent second support lines is about 50 um to about 150 um.

3. The electronic device of claim 2 , wherein among the second support lines disposed in the non-folding regions, a distance in the first direction between adjacent second support lines is about 10 um or less.

4. The electronic device of claim 1 , wherein a density of the first support lines and a density of the second support lines are relatively higher in the non-folding regions than in the folding region.

5. The electronic device of claim 1 , wherein the support plate has a weave shape in which the first support lines and the second support lines are alternately arranged in the first direction and the second direction.

6. The electronic device of claim 1 , wherein the support plate comprises at least one of polyethylene terephthalate (PET), nylon, acrylic, or spandex.

7. The electronic device of claim 1 , wherein an area of a cross-section of each of the first support lines and an area of a cross-section of each of the second support lines are the same.

8. The electronic device of claim 1 , wherein an area of a cross-section of each of the first support lines and an area of a cross-section of each of the second support lines are about 50 um to about 200 um.

9. The electronic device of claim 1 , further comprising:

a cushion member disposed between the display panel and the support plate.

10. The electronic device of claim 9 , further comprising:

a lower protective film disposed between the display panel and the cushion member.

11. The electronic device of claim 1 , wherein the support plate has a plate shape.

12. An electronic device, comprising:

a display panel comprising a plurality of non-folding regions arranged along a first direction, and a folding region disposed between the non-folding regions,

wherein the folding region is foldable along a virtual folding axis extending along a second direction crossing the first direction; and

a support plate disposed on a lower portion of the display panel, and having a weave shape in which a plurality of first openings overlapping the non-folding regions and a plurality of second openings overlapping the folding region are defined,

wherein an area of each of the first openings is smaller than an area of each of the second openings.

13. The electronic device of claim 12 , wherein the support plate comprises:

a plurality of first support lines extending in the first direction; and

a plurality of second support lines extending in the second direction and crossing the first support lines,

wherein the first openings and the second openings are formed by alternately arranging the first support lines and the second support lines in the first direction and the second direction.

14. The electronic device of claim 13 , wherein the second support lines are disposed in the non-folding regions and the folding region, and among the second support lines disposed in the folding region, a distance in the first direction between adjacent second support lines is about 50 um to about 150 um.

15. The electronic device of claim 14 , wherein among the second support lines disposed in the non-folding regions, a distance in the first direction between adjacent second support lines is about 10 um or less.

16. The electronic device of claim 13 , wherein a density of the first support lines and a density of the second support lines are relatively higher in the non-folding regions than in the folding region.

17. The electronic device of claim 12 , wherein the support plate comprises at least one of polyethylene terephthalate (PET), nylon, acrylic, or spandex.

18. The electronic device of claim 13 , wherein a width on a cross-section of each of the first support lines and a width on a cross-section of each of the second support lines are about 50 um to about 200 um.

19. The electronic device of claim 12 , wherein the support plate has a plate shape.

20. The electronic device of claim 12 , wherein at least one of the first openings and the second openings has a rhombic shape inclined with respect to a plane defined by the first direction and the second direction.
