Abstract

A flexible keyboard cover film and a control process of the flexible keyboard cover film are provided. The flexible keyboard cover film allows a user to perform a touch function and is suitable for covering a keyboard of a computer, and the flexible keyboard cover film includes a flexible transparent base material, a touch device, and an input/output (I/O) interface. The flexible transparent base material covers the keyboard. The touch device is located on the flexible transparent base material and is electrically connected to the computer through the I/O interface.

Claims

1. A flexible keyboard cover film allowing a user to perform a touch function, the flexible keyboard cover film being suitable for covering a keyboard of a computer and comprising:

a flexible transparent base material used for covering the keyboard;

a touch device located on the flexible transparent base material; and

an input/output interface for connecting the computer, wherein the touch device is electrically connected to the input/output interface and is pervious to light.

2. The flexible keyboard cover film of claim 1, wherein a material of the flexible transparent base material comprises silicone, polyimide resin, or a multi-layered polymer composite material.

3. The flexible keyboard cover film of claim 1, wherein a thickness of the flexible transparent base material is within a range from about 1 mm to about 8 mm.

4. The flexible keyboard cover film of claim 1, wherein the flexible transparent base material has a first surface and a second surface opposite to the first surface, the touch device is located on the first surface, and the second surface is configured to be in contact with the keyboard.

5. The flexible keyboard cover film of claim 1, wherein the flexible transparent base material has a first surface and a second surface opposite to the first surface, the first surface is a flat surface, the touch device is located on the first surface, and the flexible transparent base material has a plurality of cavities located on the second surface.

6. The flexible keyboard cover film of claim 1, wherein the flexible transparent base material has a first surface and a second surface opposite to the first surface, the first surface is a flat surface, the touch device is located on the first surface, and the flexible transparent base material has a plurality of protrusions located on the second surface.

7. The flexible keyboard cover film of claim 1, wherein the flexible transparent base material and the touch device are capable of being bent or rolled 180 degrees or 360 degrees.

8. The flexible keyboard cover film of claim 1, wherein the input/output interface comprises a cable input/output interface.

9. The flexible keyboard cover film of claim 1, wherein the input/output interface comprises a wireless input/output interface.

10. The flexible keyboard cover film of claim 1, wherein the touch device comprises a flexible substrate and a sensing electrode layer.

11. The flexible keyboard cover film of claim 10, wherein the sensing electrode layer is located on the flexible substrate and between the flexible substrate and the flexible transparent base material.

12. The flexible keyboard cover film of claim 1, further comprising an adhesive arranged between the touch device and the flexible transparent base material.

13. The flexible keyboard cover film of claim 1, wherein the input/output interface comprises a universal serial bus interface or a wireless transceiver module.

14. The flexible keyboard cover film of claim 1, wherein a transmittance of the flexible transparent base material and a transmittance of the touch device are respectively within a range from 80% to 100%.

15. The flexible keyboard cover film of claim 1, further comprising an adhesive arranged between the flexible transparent base material and the sensing electrode layer, wherein the sensing electrode layer is located on the flexible transparent base material.

16. A control process of a flexible keyboard cover film, comprising:

determining whether the flexible keyboard cover film is connected to a computer;

if no flexible keyboard cover film is detected to be connected to the computer, processing an input signal from a keyboard acting as a user input interface;

if the flexible keyboard cover film is detected to be connected to the computer, further determining whether an input signal from the flexible keyboard cover film and the input signal from the keyboard are both received;

if the input signal from the flexible keyboard cover film and the input signal from the keyboard are not both received, the computer processing the input signal from the flexible keyboard cover film; and

if the input signal from the flexible keyboard cover film and the input signal from the keyboard are both received, the computer ignoring the input signal from the flexible keyboard cover film and processing the input signal from the keyboard;

or the computer ignoring the input signal from the keyboard and processing the input signal from the flexible keyboard cover film.

17. The control process of claim 16, wherein when the computer detects both the input signal from the flexible keyboard cover film and the input signal from the keyboard, and a continuously detected frequency of the input signal from the keyboard is higher than a predetermined frequency, the control process comprises determining a user is using the keyboard and ignoring the input signal from the flexible keyboard cover film.

18. The control process of claim 16, wherein if the computer detects both the input signal from the flexible keyboard cover film and the input signal from the keyboard, and if no sliding action performed by a user on the flexible keyboard cover film is detected, the control process comprises determining the user is using the keyboard and ignoring the input signal from the flexible keyboard cover film.

19. The control process of claim 16, wherein if the computer detects both the input signal from the flexible keyboard cover film and the input signal from the keyboard, and if a sliding action performed by a user on the flexible keyboard cover film is detected, the control process comprises determining the user is performing the action on the flexible keyboard cover film and ignoring the input signal from the keyboard.

20. The control process of claim 16, wherein when the computer detects both the input signal from the flexible keyboard cover film and the input signal from the keyboard, and a continuously detected frequency of the input signal from the keyboard is lower than a predetermined frequency, the control process comprises determining a user is performing an action on the flexible keyboard cover film and ignoring the input signal from the keyboard.
