Abstract

Disclosed by the present invention are a fingerprint recognition module and a mobile phone, the mobile phone comprising a fingerprint recognition module, a display screen, a touch screen chip disposed on the display screen and a touch screen panel disposed on the touch screen chip, a display touch integrated circuit (IC) and a display screen touch circuit board being disposed at one end of the display screen. The present invention reduces the length of a bottom frame of a mobile phone as well as the entire mobile phone by means of silk printing, transfer printing or electroplating a decorative ring on the touch screen panel to take the place of the fingerprint recognition metal decorative ring of an ordinary mobile phone.

Claims

1. A fingerprint identification mobile phone comprising:

a display screen;

a touch screen chip, disposed on the display screen and configured to sense an external touch signal;

a touch screen panel, disposed on the touch screen chip and configured to protect the touch screen chip;

a fingerprint identification decorative ring, formed around a reserved hole of the touch screen panel;

a display screen touch circuit board, disposed at one end of the display screen;

a fingerprint identification module chip, disposed in the reserved hole and configured to sense fingerprint information; and

a fingerprint identification module circuit board, disposed under the fingerprint identification module chip and configured to connect a fingerprint identification module circuit;

wherein a shape of the fingerprint identification module chip matches a shape of the reserved hole, a width of the fingerprint identification module chip is smaller than a width of the reserved hole, and a thickness of the fingerprint identification module chip is smaller than a thickness of the touch screen panel.

2. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification decorative ring is formed around the reserved hole, and is formed by screen printing on the touch screen panel.

3. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification decorative ring is formed around the reserved hole, and is formed by transferring on the touch screen panel.

4. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification decorative ring is formed around the reserved hole, and is formed by electroplating on the touch screen panel.

5. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification decorative ring is formed around the reserved hole, and is formed by etching on the touch screen panel.

6. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification decorative ring is formed around the reserved hole, and is formed by carving on the touch screen panel.

7. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification module further comprises a reinforcing steel sheet disposed under the fingerprint identification module circuit board and configured to enhance a strength of the fingerprint identification module.

8. The fingerprint identification mobile phone as claimed in claim 7, wherein a position where the fingerprint identification module is disposed at corresponds to the one end of the display screen where the display screen touch circuit board is disposed at.

9. The fingerprint identification mobile phone as claimed in claim 8, wherein the fingerprint identification module circuit board and the reinforcing steel sheet are embedded in a gap between the touch screen panel and the display screen.

10. The fingerprint identification mobile phone as claimed in claim 1, wherein the fingerprint identification module and the touch screen panel are bonded through glue.

11. The fingerprint identification mobile phone as claimed in claim 7, wherein the reinforcing steel sheet and the fingerprint identification module circuit board are bonded through glue.

12. The fingerprint identification mobile phone as claimed in claim 1, wherein the width of the fingerprint identification decorative ring is one tenth of the width of the fingerprint identification module chip.

13. A fingerprint identification module comprising:

a fingerprint identification module chip configured to sense fingerprint information; and

a fingerprint identification module circuit board, disposed under the fingerprint identification module chip and configured to connect a fingerprint identification module circuit; and

a fingerprint identification decorative ring, disposed around the fingerprint identification module chip.

14. The fingerprint identification module as claimed in claim 13, further comprising a reinforcing steel sheet disposed under the fingerprint identification module circuit board and configured to enhance a strength of the fingerprint identification module.

15. A fingerprint identification mobile phone comprising:

a display screen;

a touch screen chip, disposed on the display screen and configured to sense an external touch signal; and

a touch screen panel, disposed on the touch screen chip and configured to protect the touch screen chip;

a fingerprint identification decorative ring, formed around a reserved hole of the touch screen panel;

a display screen touch integrated circuit (IC) and a display screen touch circuit board, disposed at one end of the display screen;

a fingerprint identification module chip, disposed in the reserved hole and configured to sense fingerprint information; and

a fingerprint identification module circuit board, disposed under the fingerprint identification module chip and configured to connect a fingerprint identification module circuit.

16. The fingerprint identification mobile phone as claimed in claim 15, wherein a position where the fingerprint identification module is disposed at corresponds to the one end of the display screen where the display screen touch IC and the display screen touch circuit board are disposed at.

17. The fingerprint identification mobile phone as claimed in claim 16, wherein the fingerprint identification module circuit board and the reinforcing steel sheet are embedded in a gap between the touch screen panel and the display screen.

18. The fingerprint identification mobile phone as claimed in claim 15, wherein a shape of the fingerprint identification module chip matches a shape of the reserved hole for the fingerprint identification module, and a width of the fingerprint identification module chip being smaller than a width of the reserved hole for the fingerprint identification module.

19. The fingerprint identification mobile phone as claimed in claim 15, wherein the fingerprint identification module and the touch screen panel are bonded through glue.

20. The fingerprint identification mobile phone as claimed in claim 15, wherein a thickness of the fingerprint identification module chip is smaller than a thickness of the touch screen panel.
