Abstract

An electronic device according to various embodiments disclosed in this document may include: a display panel; a recognition member disposed under the display panel and including a conductive pattern to recognize a signal from a pen input device; a first shielding member disposed under the recognition member; and a second shielding member disposed under the first shielding member and made of a material different than the first shielding member, wherein the second shielding member includes a component region corresponding to at least one electronic component disposed under the second shielding member, and wherein at least a portion of the second shielding member is removed from the component region.

First claim

What is claimed is:

1. An electronic device comprising:
a display panel;
a recognition member disposed under the display panel and including a conductive pattern to recognize a signal from a pen input device;
a first shielding member disposed under the recognition member and including a soft magnetic material to shield a magnetic field generated from the pen input device;
a second shielding member disposed under the first shielding member and including a conductive material to shield electromagnetic waves generated from an electronic component; and
a third shielding member disposed under the second shielding member, covering electronic components from a bottom of the second shielding member, and including a soft magnetic material to shield magnetic fields generated from the electronic components,
wherein the second shielding member includes a component region corresponding to the electronic component, wherein the electronic component is disposed under the second shielding member, and at least one hole formed in the component region; and
wherein the hole corresponds to a magnetic material disposed inside the electronic component.

2. The electronic device of claim 1 , wherein the first shielding member includes the soft magnetic material capable of shielding a magnetic field generated by the pen input device so as to prevent the magnetic field generated by the pen input device from transmitting to the second shielding member.

3. The electronic device of claim 1 , wherein
the first shielding member is made of a soft magnetic material having a higher magnetic permeability than magnetic materials disposed from the display panel to the electronic component.

4. The electronic device of claim 1 , further comprising a printed circuit board electrically connected to the electronic component,
wherein the second shielding member is disposed to cover remaining regions on the printed circuit board other than a region corresponding to the component region and is made of a material capable of shielding electromagnetic waves generated from the printed circuit board.

5. The electronic device of claim 1 , wherein the component region of the second shielding member is formed in a mesh structure.

6. The electronic device of claim 1 , further comprising an insulation member made of an insulating material and disposed at the hole of the second shielding member.

7. The electronic device of claim 5 , further comprising an insulation member made of an insulating material and disposed at the mesh structure formed in the component region of the second shielding member.

8. An electromagnetic field shielding member comprising:
a first shielding member disposed under a recognition member that is disposed under a display panel and includes a conductive pattern configured to recognize a signal from a pen input device, including a soft magnetic material to shield a magnetic field generated from the pen input device;
a second shielding member disposed under the first shielding member and including a conductive material to shield electromagnetic waves generated from an electronic component; and
a third shielding member disposed under the second shielding member, covering electronic components from a bottom of the second shielding member, and including a soft magnetic material to shield magnetic fields generated from the electronic components,
wherein the second shielding member includes a component region corresponding to the electronic component, wherein the electronic component is disposed under the second shielding member and at least one hole formed in the component region, and
wherein the hole corresponds to a magnetic material disposed inside the electronic component.

9. The electromagnetic field shielding member of claim 8 , wherein the first shielding member includes the soft magnetic material capable of shielding a magnetic field generated by the pen input device so as to prevent the magnetic field generated by the pen input device from transmitting to the second shielding member.

10. The electromagnetic field shielding member of claim 8 , wherein
the first shielding member is made of a soft magnetic material having a higher magnetic permeability than magnetic materials disposed from the display panel to the electronic component.

11. The electromagnetic field shielding member of claim 8 , wherein the second shielding member is disposed to cover remaining regions on a printed circuit board other than a region corresponding to the component region and is made of a material capable of shielding electromagnetic waves generated from the printed circuit board.

12. The electromagnetic field shielding member of claim 8 , wherein the component region of the second shielding member is formed in a mesh structure.

13. The electromagnetic field shielding member of claim 8 , further comprising an insulation member made of an insulating material and disposed at the hole of the second shielding member.

14. The electromagnetic field shielding member of claim 12 , further comprising an insulation member made of an insulating material and disposed at the mesh structure in the component region of the second shielding member.
