Abstract

A display apparatus can include a display panel, a cover glass disposed on a top face of the display panel, a core plate disposed on a bottom face of the display panel and supporting the display panel, and a bonding structure disposed between the cover glass and the core plate. The core plate can include a core groove defined therein, and the core groove is configured to accommodate the bonding structure therein.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel;
a cover glass disposed on a top face of the display panel;
a core plate disposed on a bottom face of the display panel and supporting the display panel; and
a bonding structure disposed between the cover glass and the core plate,
wherein the core plate includes a core groove defined therein, and a core lead portion,
wherein the core groove is configured to accommodate the bonding structure therein,
wherein the core lead portion protrudes from an inner wall of the core groove,
wherein the bonding structure includes a bonding upper portion and a bonding lower portion protruding from the bonding upper portion, and
wherein a protrusion protruding outwardly from the bonding lower portion and spaced apart from the bonding upper portion has a separation distance from the bonding upper portion which is greater than a height of the core lead portion.

2. The display apparatus of claim 1 ,
wherein the core lead portion of the core plate supports the bonding lower portion of the bonding structure.

3. The display apparatus of claim 2 , wherein the core lead portion of the core plate includes at least two pairs of core lead portions.

4. The display apparatus of claim 2 , wherein a cross-section of the bonding lower portion of the bonding structure has a polygonal shape.

5. The display apparatus of claim 2 , wherein a width of the bonding upper portion is greater than a width of a central area of the bonding lower portion, and
the width of the central area of the bonding lower portion is greater than a width of an area in contact with the bonding upper portion on a top face of the bonding lower portion.

6. The display apparatus of claim 2 , wherein a height of the bonding upper portion is smaller than a height of the bonding lower portion.

7. The display apparatus of claim 6 , wherein the height of the bonding lower portion is smaller than a height of the core groove.

8. The display apparatus of claim 2 , further comprising a damper installed on a bottom face of the core groove,
wherein a width of the damper is greater than a width of the bonding lower portion.

9. The display apparatus of claim 2 , wherein a cross-section of the bonding lower portion has an angular shape without an inclined face.

10. The display apparatus of claim 1 , further comprising a bonding adhesive disposed on top of the bonding structure,
wherein the bonding structure and the cover glass are attached to each other via the bonding adhesive.

11. The display apparatus of claim 1 , wherein, when an external force is applied to the cover glass and the bonding structure, the core lead portion of the core plate is bent.

12. The display apparatus of claim 1 , wherein the core lead portion of the core plate includes a plurality of core lead portions spaced apart from each other in the core groove.

13. The display apparatus of claim 12 , wherein the plurality of core lead portions are disposed at regular spacings.

14. The display apparatus of claim 12 , wherein a spacing between adjacent core lead portions among the plurality of core lead portions is greater than a width of each of the plurality of core lead portions.

15. The display apparatus of claim 1 , wherein the bonding structure has a first width, the core groove has a second width, and the first width is smaller than the second width.

16. The display apparatus of claim 1 , wherein the bonding structure has a first height, the core groove has a second height, and the first height is equal to or smaller than the second height.

17. A display apparatus comprising:
a display panel;
a cover glass disposed on a top face of the display panel;
a core plate disposed on a bottom face of the display panel and supporting the display panel; and
a bonding structure disposed between the cover glass and the core plate,
wherein the core plate includes a core groove defined therein and a core lead portion protruding from an inner wall of the core groove,
wherein the bonding structure includes a bonding upper portion and a bonding lower portion protruding from the bonding upper portion, and
wherein a protrusion protruding outwardly from the bonding lower portion and spaced apart from the bonding upper portion has a separation distance from the bonding upper portion which is greater than a height of the core lead portion.

18. The display apparatus of claim 17 ,
wherein the core lead portion of the core plate supports the bonding lower portion of the bonding structure.

19. The display apparatus of claim 18 , wherein the core lead portion of the core plate includes at least two pairs of core lead portions.

20. The display apparatus of claim 18 , wherein a cross-section of the bonding lower portion of the bonding structure has a hexagonal shape.

21. The display apparatus of claim 17 , further comprising a bonding adhesive disposed on top of the bonding structure,
wherein the bonding structure and the cover glass are attached to each other via the bonding adhesive.

22. The display apparatus of claim 17 , wherein, when an external force is applied to the cover glass and the bonding structure, the core lead portion of the core plate is bent.

23. The display apparatus of claim 17 , wherein the core lead portion of the core plate includes a plurality of core lead portions spaced apart from each other in the core groove.

24. The display apparatus of claim 17 , wherein the bonding structure has a first width, the core groove has a second width, and the first width is smaller than the second width.

25. The display apparatus of claim 17 , wherein the bonding structure has a first height, the core groove has a second height, and the first height is equal to or smaller than the second height.
