Abstract

A display device including: a display panel; a first force sensor disposed under the display panel; and a waterproofing member disposed under the display panel and disposed adjacent to the first force sensor, a part of the first force sensor and a part of the waterproofing member overlap each other in a height direction of the display panel.

Claims (48)

1. A display device, comprising:

a display panel;

a first force sensor disposed under the display panel; and

a waterproofing member disposed under the display panel and disposed adjacent to the first force sensor,

wherein a part of the first force sensor and a part of the waterproofing member overlap each other in a height direction of the display panel.

2. The display device of claim 1 ,

wherein the waterproofing member is disposed on an inner side of the first force sensor.

3. The display device of claim 1 ,

wherein the waterproofing member is disposed on an outer side of the first force sensor.

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

a frame disposed under the first force sensor; and

a first bump disposed between an upper surface of the first force sensor and a lower surface of the display panel or between a lower surface of the first force sensor and an upper surface of the frame.

5. The display device of claim 4 ,

wherein a height of the first bump is higher than a height of the first force sensor.

6. The display device of claim 4 ,

wherein a side surface of the first force sensor facing the waterproof member and a side surface of the first bump are oblique with respect to the height direction of the display panel.

7. The display device of claim 4 ,

wherein a width of the first force sensor in a first direction is larger than a width of the first bump in the first direction.

8. The display device of claim 7 ,

wherein the waterproofing member comprises:

a base film;

a first adhesive film disposed on one surface of the base film and attached to a lower surface of the frame; and

a second adhesive film disposed on the other surface of the base film and attached to the upper surface of the frame.

9. The display device of claim 8 ,

wherein the first bump is disposed under the first force sensor, and

a width of the first adhesive film in the first direction is larger than a width of the second adhesive film in the first direction.

10. The display device of claim 8 ,

wherein the first bump is disposed on the first force sensor, and

a width of the first adhesive film in the first direction is smaller than a width of the second adhesive film in the first direction.

11. The display device of claim 8 ,

wherein the base film includes a main portion and a protrusion portion protruding from the main portion, and

the protrusion portion overlaps the first force sensor.

12. The display device of claim 1 ,

wherein the first force sensor comprises a force sensing cell, and

wherein the force sensing cell comprises a driving electrode and a sensing electrode disposed on one surface of a first substrate; and

a force sensing layer disposed on one surface of a second substrate facing one surface of the first substrate.

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

a second force sensor disposed under the display panel; and

a second waterproofing member disposed under the display panel and disposed adjacent to the second force sensor.

14. The display device of claim 13 ,

wherein the first force sensor is disposed on one side of the display panel, and the second force sensor is disposed on the other side of the display panel.

15. The display device of claim 1 ,

wherein the display panel comprises a first flat area and a first curved area extending from one side of the first flat area, and

the waterproofing member and the first force sensor are disposed in the first curved area.

16. The display device of claim 15 ,

wherein a height direction of the display panel in the first curved area indicates an extending direction of a radius of curvature of the first curved area.

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

a lower panel member disposed between the display panel and the first force sensor and between the display panel and the waterproofing member.
