Abstract

Fingerprint identification control methods, touch panels and display devices are provided. The touch panel includes a substrate, a touch film layer arranged on a side of the substrate, an image processing module arranged on a position corresponding to a preset region of the touch film layer, and the image processing module includes a first module and a second module performing fingerprint identification and image capturing in a time share manner.

First claim

What is claimed is:

1. A touch panel comprising:
a substrate, and
a touch film layer arranged on a side of the substrate, an image processing module arranged on a position corresponding to a preset region of the touch film layer, and the image processing module comprising a first module and a second module performing fingerprint identification and image capturing in a time share manner,
wherein the first module is an image collecting module collecting a fingerprint image in a fingerprint identification mode and a scene image in a shooting mode in a time share manner, and the second module is an image processing module processing the fingerprint image and the scene image in a time share manner.

2. The touch panel according to claim 1 , wherein
the first module and the second module are integrated together, and are arranged at a side of the touch film layer adjacent to the substrate.

3. The touch panel according to claim 1 , further comprising: a display film layer interposed between the substrate and the touch film layer.

4. The touch panel according to claim 3 , wherein the first module is separated from the second module; and the first module is arranged between the display film layer and the touch film layer, and the second module is arranged at a side of the display film layer adjacent to the substrate.

5. The touch panel according to claim 4 , wherein an orthographic projection of a position occupied by the first module on the substrate coincides with an orthographic projection of a position occupied by the second module on the substrate.

6. The touch panel according to claim 3 , wherein the first module and the second module are integrated together, and are arranged at a side of the display film layer adjacent to the substrate.

7. The touch panel according to claim 1 ,
wherein the first module is a fingerprint identification module collecting fingerprint information and performing comparison and identification of the fingerprint information in a fingerprint identification mode; and the second module is a shooting module capturing scene images and processing the scene images in a shooting mode.

8. The touch panel according to claim 3 , wherein the first module comprises: image sensing elements arranged in an array and a fingerprint identification processor in the first module, or, an ultrasonic transmitter, a receiver, and a fingerprint identification processor located in the first module.

9. A display device, comprising the touch panel according to claim 1 .

10. A touch panel comprising:
a substrate, and
a touch film layer arranged on a side of the substrate, an image processing module arranged on a position corresponding to a preset region of the touch film layer, and the image processing module comprising a first module and a second module performing fingerprint identification and image capturing in a time share manner,
a display film layer interposed between the substrate and the touch film layer,
wherein the first module is separated from the second module; and the first module is arranged between the display film layer and the touch film layer, and the second module is arranged at a side of the display film layer adjacent to the substrate.

11. The touch panel according to claim 10 , wherein an orthographic projection of a position occupied by the first module on the substrate coincides with an orthographic projection of a position occupied by the second module on the substrate.

12. A touch panel comprising:
a substrate, and
a touch film layer arranged on a side of the substrate, an image processing module arranged on a position corresponding to a preset region of the touch film layer, and the image processing module comprising a first module and a second module performing fingerprint identification and image capturing in a time share manner,
wherein the first module is a fingerprint identification module collecting fingerprint information and performing comparison and identification of the fingerprint information in a fingerprint identification mode; and the second module is a shooting module capturing scene images and processing the scene images in a shooting mode.
