Abstract

A touch panel with fingerprint identification includes a fingerprint identification module disposed in a through hole of a first substrate. The fingerprint identification module and the first substrate are attached to a second substrate.

First claim

What is claimed is:

1. A touch panel with fingerprint identification, comprising:
a fingerprint identification module disposed in a through hole of a first substrate;
a glue between the fingerprint identification module and a sidewall of the first substrate defining the through hole to fix the fingerprint identification module to the first substrate;
a first adhesive layer disposed between the first substrate and a second substrate to attach the first substrate to the second substrate, wherein the first adhesive layer is different than the glue;
a second adhesive layer disposed between the fingerprint identification module and the second substrate to attach the fingerprint identification module to the second substrate, wherein the second adhesive layer is different than the first adhesive layer and the glue;
a covering layer disposed between the first adhesive layer and the second substrate;
a touch sensing structure disposed between and contacting the first adhesive layer and the first substrate; and
a conductive material layer disposed on a second side of the first substrate that is opposite a first side of the first substrate that contacts the first adhesive layer,
wherein the covering layer covers the glue, the second adhesive layer, the fingerprint identification module, the first adhesive layer, and the conductive material layer.

2. The touch panel with fingerprint identification of claim 1 , wherein, the first adhesive layer comprises a transparent optical adhesive.

3. The touch panel with fingerprint identification of claim 1 , wherein the second substrate comprises glass.

4. The touch panel with fingerprint identification of claim 1 , further comprising:
a shielding structure surrounding the fingerprint identification module and disposed between the first substrate and the second substrate.

5. The touch panel with fingerprint identification of claim 1 , wherein the second substrate has a thickness of less than or equal to about 0.3 mm.

6. The touch panel with fingerprint identification of claim 1 , further comprising:
a pattern structure for indicating a fingerprint identifying area.

7. The touch panel with fingerprint identification of claim 1 , wherein the covering layer comprises printed ink.

8. The touch panel with fingerprint identification of claim 1 , wherein the touch sensing structure comprises an electrode layer and a conducting wire layer.

9. The touch panel with fingerprint identification of claim 1 , wherein the second substrate has a concave portion over the fingerprint identification module.

10. A touch panel with fingerprint identification, comprising:
a fingerprint identification module disposed in a through hole of a first substrate;
a glue between the fingerprint identification module and a sidewall of the first substrate defining the through hole to fix the fingerprint identification module to the first substrate;
a first adhesive layer disposed between the first substrate and a second substrate to attach the first substrate to the second substrate, wherein the first adhesive layer is different than the glue;
a second adhesive layer disposed between the fingerprint identification module and the second substrate to attach the fingerprint identification module to the second substrate, wherein the second adhesive layer is different than the first adhesive layer and the glue;
a covering layer disposed between the first adhesive layer and the second substrate;
a touch sensing structure disposed between and contacting the first adhesive layer and the second substrate; and
a conductive material layer disposed on a second side of the first substrate that is opposite a first side of the first substrate that contacts the first adhesive layer,
wherein the covering layer covers the glue, the second adhesive layer, the fingerprint identification module, the first adhesive layer, and the conductive material layer.

11. The touch panel with fingerprint identification of claim 10 , wherein, the first adhesive layer comprises a transparent optical adhesive.

12. The touch panel with fingerprint identification of claim 10 , wherein the second substrate comprises glass.

13. The touch panel with fingerprint identification of claim 10 , further comprising:
a shielding structure surrounding the fingerprint identification module and disposed between the first substrate and the second substrate.

14. The touch panel with fingerprint identification of claim 10 , wherein the second substrate has a thickness of less than or equal to about 0.3 mm.

15. The touch panel with fingerprint identification of claim 10 , further comprising:
a pattern structure for indicating a fingerprint identifying area.

16. The touch panel with fingerprint identification of claim 10 , wherein the covering layer comprises printed ink.

17. The touch panel with fingerprint identification of claim 10 , wherein the touch sensing structure comprises an electrode layer and a conducting wire layer.

18. The touch panel with fingerprint identification of claim 10 , wherein the second substrate has a concave portion over the fingerprint identification module.

19. A touch panel with fingerprint identification, comprising:
a fingerprint identification module disposed in a through hole of a first substrate;
a glue between the fingerprint identification module and a sidewall of the first substrate defining the through hole to fix the fingerprint identification module to the first substrate;
a first adhesive layer disposed between the first substrate and a second substrate to attach the first substrate to the second substrate, wherein the first adhesive layer is different than the glue and is in direct contact with the first substrate;
a covering layer disposed between the first adhesive layer and the second substrate;
a second adhesive layer disposed between the fingerprint identification module and the covering layer to attach the fingerprint identification module to the second substrate, wherein the second adhesive layer is different than the first adhesive layer and the glue; and
a touch sensing structure disposed on the first substrate opposite the first adhesive layer,
wherein the covering layer covers the glue, the second adhesive layer, the fingerprint identification module, the touch sensing structure, and the first adhesive layer.

20. The touch panel with fingerprint identification of claim 19 , further comprising:
a pattern structure for indicating a fingerprint identifying area.
