Abstract

Disclosed is a display apparatus including a display panel and a cushion plate disposed under the display panel. The cushion plate may include a porous member and a reinforcing plate. A step in a side area of the display apparatus may be removed, thereby improving impact absorption ability and rigidity.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel for displaying an image; and
a cushion plate disposed under the display panel;
wherein the cushion plate includes a porous member, a first reinforcing plate, and a first adhesive member,
wherein a distal end of the display panel and a distal end of the cushion plate coincide or are aligned with each other, and
wherein the cushion plate includes the porous member, the first reinforcing plate, and the first adhesive member sequentially stacked in order.

2. The display apparatus of claim 1 , wherein a planar size of the display panel and a planar size of the cushion plate are same as each other.

3. The display apparatus of claim 1 , wherein the first reinforcing plate includes stainless steel (SUS) or amorphous alloy.

4. The display apparatus of claim 1 , wherein the cushion plate further includes a second reinforcing plate disposed on the first reinforcing plate.

5. The display apparatus of claim 1 , wherein a coating layer made of an alloy of copper (Cu) and nickel (Ni) is disposed on the first reinforcing plate.

6. The display apparatus of claim 1 , wherein the porous member includes a conductive metal, and is formed with a plurality of pores located inside the conductive metal.

7. The display apparatus of claim 6 , wherein the porous member is a compressed porous member having a porosity in a range of 60% or smaller, wherein the porosity is defined as a ratio of an area occupied by the plurality of pores to a unit area.

8. The display apparatus of claim 1 , wherein the first reinforcing plate is in direct contact with a top surface of the porous member.

9. A method for manufacturing a display apparatus, the method comprising:
providing a first reinforcing plate having a first surface and a second surface opposite to each other;
placing a precursor of a porous member including metal powders on the first surface of the first reinforcing plate;
sintering the precursor of the porous member to form a porous member disposed on the first reinforcing plate;
placing an adhesive member on the second surface of the first reinforcing plate;
placing a display panel on the first adhesive member; and
cutting a portion of a side area of each of the display panel and the porous member at once using a laser device.

10. A display apparatus comprising:
a display panel including a display area and a non-display area, the display area of the display panel including a pixel array for displaying an image; and
a cushion plate disposed under the display panel, wherein the cushion plate includes:
a porous member formed with a plurality of pores,
at least a first reinforcing plate on the porous member, the first reinforcing plate including a metal material, and
an adhesive member on the first reinforcing plate,
wherein for at least one side of the display apparatus, a side surface of the display panel and a side surface of the cushion plate are aligned with one another.

11. The display apparatus of claim 10 , wherein a thickness of the first reinforcing plate is 30 μm or smaller.

12. The display apparatus of claim 10 , wherein the first reinforcing plate is a metal plate or a metal sheet including at least one or a combination of stainless steel (SUS), copper (Cu), aluminum (Al), and amorphous alloy.

13. The display apparatus of claim 10 , further comprising a support member between the display panel and the cushion plate, wherein a side surface of the support member at the at least one side is aligned with the side surface of the display panel and the side surface of the cushion plate, and wherein the adhesive member is attached to the support member.

14. The display apparatus of claim 13 , wherein the supporting member is formed of plastic material including at least one or a combination of PET (polyethylene terephthalate), PC (polycarbonate), and PI (polyimide).

15. The display apparatus of claim 10 , wherein the cushion plate further comprises a second reinforcing plate between the porous member and the first reinforcing plate, the second reinforming plate including a metal material.

16. The display apparatus of claim 15 , wherein a thickness of the second reinforcing plate is 30 μm or smaller.

17. The display apparatus of claim 10 , wherein the first reinforcing plate is integrally formed with the porous member.

18. The display apparatus of claim 10 , wherein the cushion plate further includes a coating layer on the first reinforcing plate, wherein the coating layer includes at least one or a combination of copper (Cu) and nickel (Ni).

19. The display apparatus of claim 10 , wherein the porous member is a compressed porous member and a porosity of the porous member is 60% or smaller.
