Abstract

A display device and a method of manufacturing the same are disclosed. The display device includes a first panel, a panel supporter including a bottom part in which the first panel is received, a first pad that is positioned on the bottom part of the panel supporter and attaches the first panel to the panel supporter, a second panel positioned on the first panel, a cover including a surface part covering a partial outer wall of the second panel, and a second pad that is positioned under the surface part of the cover and attaches the second panel to the cover.

First claim

The invention claimed is:

1. A display device comprising:
a first panel configured to display an image on the first panel;
a panel supporter including a bottom part to which the first panel is attached and a side wall extending vertically from the bottom part, the panel supporter being an L-shape component, the bottom part and the side wall defining an L shape, the bottom part having a lower flat surface;
a first pad positioned on the bottom part of the panel supporter to attach the first panel to the panel supporter;
a second panel positioned on the first panel and displaying an image in the same manner as the first panel or controlling the image that has been displayed on the first panel, the first panel displaying the image on the first panel independently of an operation of the second panel;
a cover including a surface part covering a partial outer wall of the second panel and an outer wall part extending vertically from the surface part;
a second pad positioned under the surface part of the cover, the second pad configured to attach the second panel to the cover; and
a cover bottom attached to the lower flat surface of the bottom part,
wherein the cover and the panel supporter do not share any component.

2. The display device of claim 1 , wherein at least one of the first pad and the second pad is divided into a plurality of portions or is formed in a closed curve.

3. The display device of claim 1 , wherein the first pad and the second pad are substantially equal to or different from each other in a size and a thickness.

4. The display device of claim 1 , further comprising a third pad configured to attach an outer wall of the first panel to an outer wall of the second panel.

5. The display device of claim 4 , wherein at least one surface of each of the first to third pads has an adhesive strength.

6. The display device of claim 1 , wherein the second panel is a panel controlling the image displayed on the first panel.

7. The display device of claim 1 , further comprising a backlight unit that includes a light guide plate guiding light from light sources and a reflection plate reflecting the light incident on the light guide plate,
wherein the cover bottom and the bottom part of the panel supporter define a space between an upper surface of the cover bottom and the lower flat surface of the bottom part of the panel supporter, the light guide plate and the reflection plate of the backlight unit being received in the space.

8. A method of manufacturing a display device comprising:
forming a first pad on a bottom part of a panel supporter, the panel supporter including a side wall extending vertically from the bottom part, the panel supporter being an L-shape component, the bottom part and the side wall defining an L shape, the bottom part having a lower flat surface;
attaching a first panel configured to display an image to the first pad, the first panel displaying an image on the first panel;
forming a second pad under a surface part of a cover, the cover including an outer wall part extending vertically from the surface part;
attaching a second panel to the second pad, the second panel displaying an image in the same manner as the first panel or controlling the image that has been displayed on the first panel, the first panel displaying the image on the first panel independently of an operation of the second panel;
aligning the cover on the panel supporter; and
attaching a cover bottom to the lower flat surface of the bottom part,
wherein the second panel is a panel displaying an image or a panel controlling an image, and
wherein the cover and the panel supporter do not share any component.

9. The method of claim 8 , wherein at least one of the first panel and the second panel is transferred and attached using a vacuum adsorption method.

10. The method of claim 8 , wherein at least one surface of each of the first pad and the second pad has an adhesive strength,
wherein at least one of the first pad and the second pad is divided into a plurality of portions or is formed in a closed curve.

11. The method of claim 8 , wherein the first pad and the second pad are substantially equal to or different from each other in a size and a thickness.

12. The method of claim 8 , further comprising attaching an outer wall of the first panel to an outer wall of the second panel using a third pad.

13. The method of claim 12 , wherein at least one surface of each of the first to third pads has an adhesive strength.

14. The method of claim 8 , wherein the second panel is a panel controlling the image displayed on the first panel.

15. The method of claim 8 , further receiving a backlight unit including a light guide plate and a reflection plate in a space between the lower flat surface of the bottom part of the panel supporter and an upper surface of the cover bottom.

16. The display device of claim 1 , wherein at least one of the first pad and the second pad is formed in a closed curve.

17. The display device of claim 1 , wherein the first pad and the second pad are different from each other in a size and a thickness.

18. The method of claim 8 , wherein at least one surface of each of the first pad and the second pad has an adhesive strength,
wherein at least one of the first pad and the second pad is formed in a closed curve.

19. The method of claim 8 , wherein the first pad and the second pad are different from each other in a size and a thickness.

20. The display device of claim 1 , wherein wherein the cover bottom includes a bottom part parallel to the bottom part of the panel supporter and a vertical wall extending vertically from the bottom part of the cover bottom, the vertical wall of the cover bottom being aligned with the side wall of the panel supporter, the bottom part of the panel supporter being spaced apart from the bottom part of the bottom cover by the vertical wall of the cover bottom.
