Abstract

A method includes determining a presence of a protective liner on a display of a device using a capacitive sensor positioned proximate the display. An alignment guide is generated on the display responsive to determining the presence of the protective liner. A device includes a display, a capacitive sensor positioned proximate the display, and a processor to determine a presence of a protective liner on the display using the capacitive sensor and to generate an alignment guide on the display responsive to determining the presence of the protective liner.

First claim

What is claimed is:

1. A method, comprising: determining a presence of a protective liner on a display of a device using a capacitive sensor positioned proximate the display; and generating an alignment guide on the display for aligning the protective liner responsive to determining the presence of the protective liner.

2. The method of claim 1 , wherein the capacitive sensor comprises at least two electrodes, and determining the presence comprises determining the presence of a conductive element disposed on the protective liner proximate at least two electrodes.

3. The method of claim 1 , wherein the capacitive sensor comprises a touch sensor of the device.

4. The method of claim 3 , further comprising calibrating the touch sensor after determining the presence of the protective liner.

5. The method of claim 1 , further comprising determining an alignment of the protective liner relative to the display using the capacitive sensor.

6. The method of claim 5 , further comprising providing alignment feedback information on the display based on the determined alignment.

7. The method of claim 1 , further comprising generating a warning message on the display responsive to detecting an absence of the protective liner.

8. The method of claim 1 , wherein the protective liner comprises a conductive element.

9. The method of claim 8 , wherein the protective liner comprises a protective layer contacting the display and a release layer disposed above the protective layer, wherein the conductive element is disposed on the release layer.

10. The method of claim 1 , wherein the protective liner comprises a protective layer contacting the display and a release layer disposed above the protective layer, an alignment graphic is disposed on the release layer, and the alignment guide corresponds in position to the alignment graphic when the protective liner is aligned with the display.

11. A device, comprising: a display; a capacitive sensor positioned proximate the display; and a processor circuit to determine a presence of a protective liner on the display using the capacitive sensor and to generate an alignment guide on the display for aligning the protective liner responsive to determining the presence of the protective liner.

12. The device of claim 11 , wherein the capacitive sensor comprises at least two electrodes.

13. The device of claim 11 , wherein the capacitive sensor comprises a touch sensor of the device.

14. The device of claim 13 , wherein the processor is to calibrate the touch sensor after determining the presence of the protective liner.

15. The device of claim 11 , wherein the processor is to determine an alignment of the protective liner relative to the display using the capacitive sensor.

16. The device of claim 15 , wherein the processor is to generate an alignment guide indicating alignment feedback information on the display based on the determined alignment.

17. The device of claim 11 , wherein the processor is to generate a warning message on the display responsive to detecting an absence of the protective liner.

18. The device of claim 11 , wherein the protective liner comprises a conductive element.

19. The device of claim 18 , wherein the protective liner comprises a protective layer contacting the display and a release layer disposed above the protective layer, wherein the conductive element is disposed on the release layer.

20. The device of claim 11 , wherein the protective liner comprises a protective layer contacting the display and a release layer disposed above the protective layer, an alignment graphic is disposed on the release layer, and the alignment guide corresponds in position to the alignment graphic when the protective liner is aligned with the display.
