Abstract

A display device includes: a display panel having a display area; a protective cover disposed on a surface of the display panel in a position overlapping the display area, the protective cover having an opening overlapping the display area and extending in a thickness direction opposite from the display panel, the protective cover including a first layer; and a fingerprint sensor disposed at least partially in the opening.

Claims (40)

1. A display device comprising:

a display panel having a display area;

a flexible circuit board disposed on the display panel and having an opening therein;

a protective cover disposed on a surface of the display panel between the display panel and the flexible circuit board in a position overlapping the display area, the opening extending through the protective cover, the protective cover overlapping the display area and extending in a thickness direction opposite from the display panel, the protective cover including a first layer; and

a fingerprint sensor disposed at least partially in the opening.

2. The display device of claim 1 , wherein the opening exposes at least a part of the surface of the display panel, and

wherein the fingerprint sensor has a surface directly facing the display panel without any intervening layers.

3. The display device of claim 2 , wherein the surface of the fingerprint sensor is directly disposed on the display panel.

4. The display device of claim 2 , wherein the surface of the fingerprint sensor is spaced away from the display panel by an air gap.

5. The display device of claim 1 , wherein the protective cover comprises a first adhesive layer disposed on a surface of the first layer facing the display panel.

6. The display device of claim 1 , wherein the first layer comprises a light shielding pigment.

7. The display device of claim 1 , wherein the display panel comprises a plurality of light emitting elements, and

wherein the fingerprint sensor is configured to recognize a fingerprint of a user using the light emitted from the organic light emitting elements.

8. The display device of claim 1 , wherein at least a part of the fingerprint sensor is inserted into the opening, facing the display panel.

9. The display device of claim 8 , further comprising an adhesive member attaching the fingerprint sensor to the surface of the display panel, wherein the adhesive member is spaced apart from sidewalls of the opening.

10. The display device of claim 1 , wherein the protective cover further comprises a second layer disposed on a surface of the first layer.

11. The display device of claim 10 , wherein the opening comprises a first opening formed in the first layer and a second opening formed in the second layer,

wherein the first opening has a planar surface area smaller than that of the fingerprint sensor, and

wherein the second opening has a same planar surface area as that of the fingerprint sensor.

12. The display device of claim 11 , further comprising a shoulder between the first and second layers,

wherein the fingerprint sensor is attached to the shoulder.

13. The display device of claim 10 , wherein the protective cover comprises a cover member including the first layer, which comprises protective tape, and the second layer which comprises a cushioning member including at least one of a heat dissipation member and a latent heat member.

14. The display device of claim 1 , wherein the protective cover further comprises a third opening overlapping the display area.

15. The display device of claim 14 , wherein at least one optical sensor is received in the third opening.

16. A display device comprising:

a display panel having a display area;

a flexible circuit board disposed on the display panel and having an opening therein;

a protective cover disposed on a surface of the display panel, the protective cover comprising a first layer overlapping the display area; and

a fingerprint sensor disposed on a surface of the protective cover, and at least partially in the opening,

wherein the first layer comprises a first area and a second area surrounding the first area, the first area being a light transmitting area, and

wherein the fingerprint sensor is disposed overlapping the first area and is co-planar with the protective cover.

17. The display device of claim 16 , wherein the second area is an opaque area.

18. The display device of claim 16 , wherein the protective cover comprises a first adhesive layer disposed on a surface of the first layer facing the display panel.

19. The display device of claim 16 , wherein the display panel comprises a plurality of light emitting elements, and

wherein the fingerprint sensor is configured to recognize a fingerprint of a user's finger positioned on the display panel using the light emitted from the organic light emitting elements.

20. The display device of claim 16 , wherein at least a part of the fingerprint sensor is inserted into the protective cover overlapping the first area.

21. The display device of claim 20 , further comprising a second layer disposed on the surface of the protective cover, the second layer comprising an opening overlapping the first area.

22. The display device of claim 21 , wherein the first layer further comprises a second adhesive layer overlapping the second area facing the second layer, wherein the first area has a planar surface area smaller than that of the fingerprint sensor, and the opening has a planar surface area same as that of the fingerprint sensor.

23. The display device of claim 22 , wherein the first layer comprises a non-overlap area which does not overlap with the second layer, and the fingerprint sensor is attached to the non-overlap area of the protective cover.

24. The display device of claim 21 , wherein the protective cover comprises a cover member including the first layer, which comprises protective tape, and the second layer which comprises a cushioning member including at least one of a heat dissipation member and a latent heat member.
