Abstract

An image capturing device including a cover plate, an image capturing module, a frame body, a first adhesive layer, and a second adhesive layer is provided. The frame body and the image capturing module are located on the same side of the cover plate. The frame body is joined to the cover plate through the first adhesive layer. The image capturing module is joined to the frame body through the second adhesive layer. An orthographic projection of the second adhesive layer on the cover plate falls within an orthographic projection of the frame body on the cover plate.

First claim

What is claimed is:

1. An image capturing device, comprising:
a cover plate;
an image capturing module;
a frame body, wherein the frame body and the image capturing module are located on the same side of the cover plate;
a first adhesive layer, wherein the frame body is joined to the cover plate through the first adhesive layer; and
a second adhesive layer, wherein the image capturing module is joined to the frame body through the second adhesive layer, and an orthographic projection of the second adhesive layer on the cover plate falls within an orthographic projection of the frame body on the cover plate.

2. The image capturing device of claim 1 , wherein the cover plate comprises a transparent cover plate, an organic light emitting display panel, a touch panel or a combination of at least two of the above.

3. The image capturing device of claim 1 , wherein an air gap is present between the cover plate and the image capturing module.

4. The image capturing device of claim 1 , wherein the image capturing module comprises:
a carrier;
a sensor, disposed on the carrier;
a band pass filter component, disposed on the sensor;
a collimator, disposed on the band pass filter component, and an air gap being present between the collimator and the cover plate; and
at least one supporting member, disposed on the carrier and located at a periphery of the sensor.

5. The image capturing device of claim 4 , wherein the band pass filter component is an infrared filter.

6. The image capturing device of claim 4 , wherein the second adhesive layer is located between the carrier and the frame body.

7. The image capturing device of claim 6 , wherein the carrier is joined to the frame body through the second adhesive layer, the at least one supporting member is located between the second adhesive layer and the sensor, and an air gap is present between the at least one supporting member and the cover plate.

8. The image capturing device of claim 7 , wherein a distance is kept between the at least one supporting member and the sensor.

9. The image capturing device of claim 7 , wherein the at least one supporting member is in contact with the carrier, the sensor, the band pass filter component and the collimator, and the at least one supporting member fixes the sensor, the band pass filter component and the collimator on the carrier.

10. The image capturing device of claim 6 , wherein the at least one supporting member is located between the carrier and the frame body, the at least one supporting member is joined to the frame body through the second adhesive layer, and at least a portion of an orthographic projection of the at least one supporting member on the cover plate falls within the orthographic projection of the frame body on the cover plate.

11. A fingerprint image capturing device, comprising:
a cover plate;
an image capturing module, comprising:
a carrier;
a sensor, disposed on the carrier;
a band pass filter component, disposed on the sensor;
a collimator, disposed on the band pass filter component; and
at least one supporting member, disposed on the carrier and located at a periphery of the sensor;

a frame body, wherein the frame body and the image capturing module are located on the same side of the cover plate;
a first adhesive layer, wherein the frame body is joined to the cover plate through the first adhesive layer; and
a second adhesive layer, wherein the image capturing module is joined to the frame body through the second adhesive layer, and an orthographic projection of the second adhesive layer on the cover plate falls within an orthographic projection of the frame body on the cover plate.

12. The fingerprint image capturing device of claim 11 , wherein the cover plate comprises a transparent cover plate, an organic light emitting display panel, a touch panel or a combination of at least two of the above.

13. The fingerprint image capturing device of claim 11 , wherein an air gap is present between the cover plate and the collimator.

14. The fingerprint image capturing device of claim 11 , wherein the band pass filter component is an infrared filter.

15. The fingerprint image capturing device of claim 11 , wherein the second adhesive layer is located between the carrier and the frame body.

16. The fingerprint image capturing device of claim 15 , wherein the carrier is joined to the frame body through the second adhesive layer, the at least one supporting member is located between the second adhesive layer and the sensor, and an air gap is present between the at least one supporting member and the cover plate.

17. The fingerprint image capturing device of claim 16 , wherein a distance is kept between the at least one supporting member and the sensor.

18. The fingerprint image capturing device of claim 16 , wherein the at least one supporting member is in contact with the carrier, the sensor, the band pass filter component and the collimator, and the at least one supporting member fixes the sensor, the band pass filter component and the collimator on the carrier.

19. The fingerprint image capturing device of claim 15 , wherein the at least one supporting member is located between the carrier and the frame body, the at least one supporting member is joined to the frame body through the second adhesive layer, and at least a portion of an orthographic projection of the at least one supporting member on the cover plate falls within the orthographic projection of the frame body on the cover plate.
