Abstract

A display apparatus is disclosed, which includes: a display panel; a first adhesive layer disposed on the display panel; a cover layer disposed on the first adhesive layer; and a biometric sensor disposed between the first adhesive layer and the cover layer.

Claims

1. A display apparatus, comprising:

a display panel including an active substrate, wherein the active substrate includes a display area and a non-display area adjacent to the display area;

a first adhesive layer disposed on the display panel;

a cover layer disposed on the first adhesive layer;

a biometric sensor disposed between the first adhesive layer and the cover layer;

an integrated circuit disposed at a side of the display panel opposite to the cover layer; and

a conductive adhesive layer;

wherein the integrated circuit is attached to the non-display area through the conductive adhesive layer.

2. The display apparatus of claim 1, wherein the first adhesive layer has a first thickness in a range from 10 μ

m to 200 μ

m.

3. The display apparatus of claim 1, wherein the cover layer includes a recess portion and at least a part of the biometric sensor is embedded in the recess portion.

4. The display apparatus of claim 3, wherein the cover layer has a second thickness corresponding to the recess portion and the second thickness is in a range from 30 μ

m to 300 μ

m.

5. The display apparatus of claim 3, wherein the cover layer includes a protruding portion corresponding to the recess portion, the protruding portion is disposed at a first side of the cover layer, the recess portion is disposed at a second side of the cover layer, and the first side is opposite to the second side.

6. The display apparatus of claim 1, further comprising a second adhesive layer disposed between the biometric sensor and the cover layer.

7. The display apparatus of claim 6, wherein the first adhesive layer has a first thickness, the second adhesive layer has a third thickness, and the third thickness is less than the first thickness.

8. The display apparatus of claim 6, wherein the first adhesive layer and the second adhesive layer respectively have a refractive index in a range from 1.41 to 1.51.

9. The display apparatus of claim 1, wherein the cover layer has a fourth thickness in a range from 30 μ

m to 300 μ

m.

10. The display apparatus of claim 1, wherein the integrated circuit is disposed on the non-display area and the integrated circuit is electrically connected to the biometric sensor.

11. The display apparatus of claim 1, wherein the biometric sensor overlaps the display area in a first direction perpendicular to the active substrate.

12. The display apparatus of claim 11, wherein the biometric sensor further overlaps the non-display area in the first direction.

13. The display apparatus of claim 1, wherein the display panel further includes a counter substrate disposed opposite to the active substrate, the non-display area includes a first region and a second region, the first region overlaps the counter substrate in a first direction perpendicular to the active substrate, and the second region does not overlap the counter substrate in the first direction.

14. The display apparatus of claim 13, wherein the biometric sensor overlaps the first region in the first direction.

15. The display apparatus of claim 14, wherein the biometric sensor further overlaps the second region in the first direction.

16. The display apparatus of claim 13, wherein the biometric sensor overlaps the second region in the first direction.

17. The display apparatus of claim 1, wherein the cover layer includes an extending portion which does not overlap the display panel in a second direction perpendicular to the cover layer and the biometric sensor is disposed on the extending portion.

18. The display apparatus of claim 1, wherein the biometric sensor comprises a fingerprint sensor, an iris sensor, a retina sensor, a facial sensor, a vein sensor, a voice sensor, a motion sensor, a gesture sensor, or a DNA sensor.
