Abstract

A display device includes a display panel, a first force sensor, a first vibration generator, and a first electromagnetic wave shielding member. The first force sensor is disposed under the display panel. The first vibration generator is disposed under the display panel and adjacent to the first force sensor. The first electromagnetic wave shielding member surrounds side surfaces of the first vibration generator.

2. The display device of claim 1 , wherein an upper surface of the first electromagnetic wave shielding member is closer to the display panel than an upper surface of the first vibration generator.

3. The display device of claim 1 , further comprising:

a first adhesive layer attached to the first electromagnetic wave shielding member, the first adhesive layer being between the lower surface of the display panel and the first electromagnetic wave shielding member; and

a second adhesive layer attached to the first electromagnetic wave shielding member and the first upper surface of the middle frame.

4. The display device of claim 1 , wherein:

the first electromagnetic wave shielding member is integrally formed with and protrudes from the first upper surface of the middle frame; and

the display device further comprises a third adhesive layer attached to the first electromagnetic wave shielding member, the third adhesive layer being between the lower surface of the display panel and the first electromagnetic wave shielding member.

5. The display device of claim 1 , wherein the first vibration generator and the first electromagnetic wave shielding member are accommodated in a first accommodating hole formed in a second upper surface of the middle frame, the second upper surface of the middle frame being closer to the display panel than the first upper surface of the middle frame.

6. The display device of claim 5 , wherein the first electromagnetic wave shielding member is between the lower surface of the display panel and a floor surface of the first accommodating hole, the floor surface of the first accommodating hole corresponding to the first upper surface of the middle frame.

7. The display device of claim 5 , further comprising:

a first adhesive layer attached to the first electromagnetic wave shielding member, the first adhesive layer being between the lower surface of the display panel and the first electromagnetic wave shielding member; and

a second adhesive layer attached to the first electromagnetic wave shielding member and the floor surface of the first accommodating hole.

8. The display device of claim 5 , wherein the first electromagnetic wave shielding member is integrally formed with the middle frame and protrudes from the floor surface of the first accommodating hole.

9. The display device of claim 1 , wherein the first vibration generator is configured to vibrate in response to detection of a force via the first force sensor.

10. The display device of claim 1 , further comprising:

a second force sensor disposed under the display panel;
