Abstract

A display device includes a display module, a first supporter under the display module, a second supporter under the display module, the first and second supporters being arranged in a first direction with a space therebetween, and a digitizer module under the first and second supporters and including a first opening extending in a second direction crossing the first direction and second openings respectively extending along the first direction from both ends of the first opening. The first opening overlaps with the space between the first supporter and the second supporter.

First claim

What is claimed is:

1. A display device comprising:
a display module;
a first supporter under the display module;
a second supporter under the display module, the first and second supporters being arranged with each other along a first direction; and
a digitizer module under the first and second supporters,
wherein the digitizer module comprises:
a first portion under the first supporter;
a second portion under the second supporter and separated from the first portion; and
a flexible printed circuit board that connects the first portion to the second portion.

2. The display device of claim 1 , wherein each of the first and second portions comprises a pair of first sides facing oppositely away from each other in the first direction and a pair of second sides facing oppositely away from each other in a second direction crossing the first direction, and
wherein the flexible printed circuit board extends in the first direction and is connected to one of the second sides of the first portion and one of the second sides of the second portion.

3. The display device of claim 1 , wherein a distance in the first direction between the first portion and the second portion is smaller than a distance in the first direction between the first supporter and the second supporter.

4. The display device of claim 1 , further comprising:
a first case under the first portion; and
a second case under the second portion.

5. The display device of claim 4 , wherein a distance in the first direction between the first portion and the second portion is smaller than a distance in the first direction between the first case and the second case.

6. The display device of claim 1 , wherein the display module comprises:
non-folding areas arranged along the first direction; and
a folding area between the non-folding areas,
wherein the first and second supporters are under the non-folding areas, respectively.

7. The display device of claim 6 , a distance in the first direction between the first portion and the second portion is smaller than a length in the first direction of the folding area.

8. A display device comprising:
a display module including non-folding areas arranged along a first direction and a folding area between the non-folding areas;
a first supporter and a second supporter under the non-folding areas, respectively; and
a digitizer module under the first and second supporters and having an opening overlapping the folding area, the opening extending in a second direction crossing the first direction,
wherein a length in the second direction of the opening is smaller than a length in the first direction of the digitizer module.

9. The display device of claim 8 , wherein a length in the first direction of the opening is equal to a length in the first direction of the folding area.

10. The display device of claim 8 , wherein a length in the first direction of the opening is larger than a distance in the first direction between the first supporter and the second supporter.

11. The display device of claim 8 , further comprising:
a first case under the digitizer module and overlapping the first supporter; and
a second case under the digitizer module and overlapping the second supporter.

12. The display device of claim 11 , wherein a length in the first direction of the opening is larger than a distance in the first direction between the first case and the second case.
