Abstract

A dam member and display apparatus including the same. According to an embodiment of the present invention, a dam member includes an interception block having a long side and a short side, and a cover sheet attached to an upper surface or a lower surface of the interception block, wherein the cover sheet includes a surface extending in a direction of the long side of the interception block.

Claims

1. A dam member comprising:

an interception block having a long side and a short side, an upper surface and a lower surface; and

a cover sheet attached to the upper surface or the lower surface of the interception block,

wherein the cover sheet has a surface projecting in a direction of the long side of the interception block.

2. The dam member of claim 1, wherein a length of the cover sheet extending in the direction of the long side of the interception block is equal to or smaller than a length of the long side of the interception block.

3. The dam member of claim 1, further comprising an adhesive member on a surface of the interception block opposite to a surface to which the cover sheet is attached.

4. A display apparatus comprising:

a display module comprising a display region and a circuit region;

a window facing the display module and comprising a button portion;

a bonding member between the display region of the display module and the window, and configured to bond the display module and the window to each other; and

a dam member along a boundary between the display region and the circuit region to prevent or reduce the bonding member from overflowing from the display region,

wherein the dam member comprises an interception block configured to prevent or reduce the bonding member from penetrating into the circuit region, and a cover sheet configured to prevent or reduce the bonding member from penetrating into the button portion.

5. The display apparatus of claim 4, wherein the cover sheet is on an upper surface or a lower surface of the interception block and covers at least a part of the button portion.

6. The display apparatus of claim 5, wherein the cover sheet is between the interception block and the display module, and has a surface that projects toward the circuit region.

7. The display apparatus of claim 6, wherein the projecting surface of the cover sheet is between the button portion and the circuit region of the display module.

8. The display apparatus of claim 4, wherein the cover sheet is attached to the interception block.

9. The display apparatus of claim 4, wherein the interception block and the cover sheet are integrated as one body.

10. The display apparatus of claim 4, wherein the interception block is between the display module and the window, and along a circumference of a side surface of the bonding member.

11. The display apparatus of claim 4, wherein the window comprises a button driving portion corresponding to the circuit region, the button driving portion is on a lower side of the window,

wherein the cover sheet covers at least a part of the button driving portion.

12. The display apparatus of claim 11, wherein a surface of the interception block that faces the display module and a surface of the button driving portion that faces the display module are positioned on a same horizontal line.

13. The display apparatus of claim 11, wherein the cover sheet comes in contact with a surface of the button driving portion that faces the display module.

14. The display apparatus of claim 11, wherein the cover sheet further has a surface that projects toward the circuit region, and

the projecting surface and the bottom driving portion overlap each other at least partly on a same vertical line.

15. The display apparatus of claim 4, further comprising an integrated circuit chip in the circuit region.

16. The display apparatus of claim 15, wherein the interception block covers at least a part of the integrated circuit chip.

17. The display apparatus of claim 15, wherein the display module comprises a first substrate and a second substrate, the second substrate corresponds to the display region and is on the first substrate, and

the integrated circuit chip is on the first substrate corresponding to the circuit region.

18. The display apparatus of claim 4, further comprising a connection member having one side connected to the display module.

19. The display apparatus of claim 18, wherein the cover sheet covers one side of the connection member.

20. The display apparatus of claim 18, wherein the display module comprises a display panel and a touch panel on the display panel, and

one side of the connection member is connected to the touch panel.
