Abstract

Disclosed is a display apparatus including a display panel including a front portion, a bent portion, and a pad portion bent from the bent portion and positioned under the front portion, a first plate disposed between the front portion and the pad portion and disposed under the front portion, and a second plate disposed between the front portion and the pad portion and disposed on a top face of the pad portion, wherein the first plate includes a porous member, wherein the second plate includes a transparent area.

First claim

What is claimed is:

1 . A display apparatus comprising:
a display panel including a front portion, a bent portion, and a pad portion bent from the bent portion and positioned under the front portion; a first plate disposed between the front portion and the pad portion and disposed under the front portion; a second plate disposed between the front portion and the pad portion and disposed on a top face of the pad portion; and a flexible circuit board connected to a distal end of a bottom of the pad portion, wherein the first plate includes a porous member, wherein the second plate includes a transparent area and a non-transparent area, wherein the flexible circuit board vertically overlap the transparent area and vertically non-overlap the non-transparent area.

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

3 . The display apparatus of claim 1 , wherein the second plate includes at least one of polyethylene terephthalate (PET), polyimide (PI), or polyethylene naphthalate (PEN).

4 . The display apparatus of claim 1 , wherein the device further comprises a connection member disposed between the first plate and the second plate.

5 . The display apparatus of claim 1 , wherein thicknesses of the first plate and the second plate are different from each other.

6 . The display apparatus of claim 3 ,
wherein the non-transparent area includes a porous member.

7 . The display apparatus of claim 1 , wherein the first plate has a larger area size than an area size of the second plate.

8 . The display apparatus of claim 1 , wherein the second plate includes a second plate adhesive layer disposed on one face thereof,
wherein the second plate is fixed to the first plate via the second plate adhesive layer.

9 . The display apparatus of claim 1 , wherein the second plate is made of an adhesive material,
wherein the adhesive material includes at least one of OCA (Optical Clear Adhesive), OCR (Optical Clear Resin), or PSA (Pressure Sensitive Adhesive).

10 . The display apparatus of claim 9 , wherein the second plate is in direct contact with the first plate.

11 . A display apparatus comprising:
a display panel including a first portion for displaying an image and a second portion with a driver circuit, wherein at least a part of the display panel is bent such that the second portion is positioned under the first portion; a first plate disposed below the first portion of the display panel; a second plate disposed below the first plate and on a top surface of the second portion of the display panel, wherein at least a part of the second plate is transparent; and a circuit board attached to a bottom surface of the second portion of the display panel, wherein the circuit board overlaps the part of the second plate that is transparent, wherein another part of the second plate is non-transparent.

12 . The display apparatus of claim 11 , wherein the transparent part of the second plate is formed from at least one or a combination of polyethylene terephthalate (PET), polyimide (PI), or polyethylene naphthalate (PEN).

13 . The display apparatus of claim 11 , further comprising a connection member disposed between the first plate and the second plate.

14 . The display apparatus of claim 11 , further comprising an adhesive layer on the transparent part of the second plate, wherein the adhesive layer is attached to the first plate, and wherein the adhesive layer includes at least one or a combination of optical clear adhesive (OCA), optical clear resin (OCR), and pressure sensitive adhesive (PSA).

15 . The display apparatus of claim 11 , wherein at least the transparent part of the second plate includes an adhesive material, and wherein the transparent part of the second plate is directly attached to the first plate.

16 . The display apparatus of claim 11 , wherein at least a part of the first plate is formed of a porous member including a conductive metal and a plurality of pores formed within the conductive metal.

17 . A display apparatus comprising:
a display panel including a first portion for displaying an image and a second portion with a driver circuit, wherein at least a part of the display panel is bent such that the second portion is positioned under the first portion; a first plate disposed below the first portion of the display panel; a second plate disposed below the first plate and on a top surface of the second portion of the display panel, wherein at least a part of the second plate is transparent; and a circuit board attached to a bottom surface of the second portion of the display panel, wherein the circuit board overlaps the part of the second plate that is transparent, wherein one or more indentations are formed at an interface between the circuit board and the bottom surface of the second portion of the display panel.

18 . The display apparatus of claim 17 , wherein the circuit board is attached to the bottom surface of the second portion of the display panel with a conductive adhesive, and wherein one or more conductive balls in the conductive adhesive are disposed at the interface.
