Abstract

A display device includes a display panel, a touch screen panel and a receiving container. The display panel displays an image. The touch screen panel is spaced apart from the display panel. The receiving container receives the display panel and has a venting part facing a side surface of the display panel to reduce a pressure difference between a pressure in a space between the display panel and the touch screen panel of the display device and a pressure exterior to the display device.

Claims

1. A display device comprising:

a display panel which displays an image;

a touch screen panel disposed above the display panel; and

a receiving container which receives the display panel and has a venting part facing a side surface of the display panel to adjust a pressure of a space between the display panel and the touch screen panel.

2. The display device of claim 1, wherein the receiving container comprises a mold frame which supports the display panel.

3. The display device of claim 2, wherein the venting part has an air hole formed through the mold frame, the air hole extending from an inner side surface to an outer side surface of the mold frame.

4. The display device of claim 3, wherein the air hole has a zigzag shape.

5. The display device of claim 3, wherein the air hole has a serpentine shape.

6. The display device of claim 2, wherein the venting part has an air hole formed through the mold frame, the air hole extending from the inner side surface toward a lower bottom surface of the mold frame.

7. The display device of claim 6, wherein the air hole comprises:

a first straight portion extending from an opening at the inner side surface of the mold frame in a first direction substantially toward an outer side surface of the mold frame;

a first bent portion connecting the first straight portion to a second straight portion, the second straight portion extending from the first bent portion in a second direction substantially perpendicular to the first direction downward toward the bottom surface of the mold frame;

a second bent portion connecting the second straight portion to a third straight portion, the third straight portion extending from the second bent portion in the first direction;

a third bent portion connecting the third straight portion to a fourth straight portion, the fourth straight portion extending from the third bent portion in the second direction;

a fourth bent portion connecting the fourth straight portion to a fifth straight portion, the fifth straight portion extending from the fourth bent portion in a third direction substantially opposite to the first direction; and

a fifth bent portion connecting the fifth straight portion to a sixth straight portion, the sixth straight portion extending from the fifth bent portion in the second direction to an opening at the bottom surface of the mold frame.

8. The display device of claim 6, wherein the air hole has a serpentine shape.

9. The display device of claim 2, wherein the venting part comprises:

an expansion space formed in the mold frame;

a first air hole formed from the expansion space to an outer side surface of the mold frame; and

a second air hole formed from the expansion space to an inner side surface of the mold frame.

10. The display device of claim 9, wherein a width of the expansion space is greater than a width of the first air hole and a width of the second air hole.

11. The display device of claim 9, wherein the venting part further comprises a plurality of first air holes.

12. The display device of claim 2, wherein the venting part further comprises a porous venting portion formed through the mold frame from an inner side surface of the mold frame to an outer side surface of the mold frame.

13. The display device of claim 12, wherein the porous venting part further comprises a foam resin or a porous fabric.

14. The display device of claim 1, wherein the receiving container further comprises:

a mold frame which supports the display panel;

a chassis member on the mold frame to support the touch screen panel;

a first adhesive member interposed between the mold frame and the chassis member; and

a second adhesive member interposed between the chassis member and the touch screen panel.

15. The display device of claim 14, wherein the venting part comprises an air hole formed through the first adhesive member between the mold frame and the chassis member.

16. The display device of claim 1, further comprising:

a backlight assembly disposed under the display panel to supply the display panel with light; and

a bottom chassis combined with the receiving container to receive the backlight assembly.

17. A method of compensating for pressure changes of a display device, the method comprising:

injecting air into a space between a chassis member and an outer surface of a mold frame;

injecting the air in the space between the chassis member and the outer surface of the mold frame into an expansion space through a first air hole having a width less than a width of the expansion space;

injecting the air in the expansion space into a second air hole having a width less than the width of the expansion space; and

injecting the air in the second air hole into a space between a display panel and a touch screen panel of the display device to increase a pressure of the space between the display panel and the touch screen panel of the display device.

18. The method of claim 17, wherein the air is injected into the expansion space through a plurality of first air holes.

19. The method of claim 17, wherein a pressure of the air in the expansion space is greater than a pressure of the air in the first air hole and the second air hole.

20. A method of compensating for pressure changes of a display device having a first air hole, a second air hole and an expansion space, the method comprising:

injecting air from a space between a display panel and a touch screen panel of the display device into the second air hole, the second air hole having a width less than a width of the expansion space;

injecting the air in the second air hole into the expansion space;

injecting the air in the expansion space into the first air hole, the first air hole having a width less than the width of the expansion space; and

injecting the air in the first air hole into a space between a chassis member and an outer surface of a mold frame to decrease a pressure of the space between the display panel and the touch screen panel of the display device.

21. The method of claim 20, wherein the air is injected into the space between the chassis member and the outer surface of the mold frame through a plurality of first air holes.

22. The method of claim 20, wherein a pressure of the air in the expansion space is greater than a pressure of the air in the first air hole and the second air hole.
