Electronic device with capacitive touch-sensitive display

1. A method comprising:

detecting a cover on a touch-sensitive display of an electronic device;

automatically increasing sensitivity of the touch-sensitive display to a touch when the cover is detected.

2. The method according to claim 1 , wherein automatically increasing comprises maintaining increased sensitivity while the cover covers the touch-sensitive display.

3. The method according to claim 1 , wherein automatically increasing sensitivity comprises automatically decreasing a threshold value utilized to detect a touch based on a comparison to signals from touch sensors of the touch-sensitive display.

4. The method according to claim 1 , wherein automatically increasing sensitivity comprises automatically increasing a drive voltage applied across electrodes of the touch-sensitive display.

5. The method according to claim 1 , wherein detecting a cover comprises detecting a sheet sized to overlie the display.

6. The method according to claim 1 , wherein detecting a cover comprises detecting a case around a housing of the electronic device.

7. The method according to claim 1 , wherein detecting comprises utilizing at least one sensor of the electronic device to detect the cover.

8. The method according to claim 1 , wherein detecting comprises utilizing at least one of a magnetic sensor, a Hall effect sensor, and a switch to detect the cover.

9. A computer-readable storage device having computer-readable code executable by at least one processor of the electronic device to perform the method of claim 1 .

10. An electronic device comprising:

a capacitive touch-sensitive display;

a sensor arranged and constructed to detect a cover on the touch-sensitive display;

a processor coupled to the sensor and the touch-sensitive display to automatically increase sensitivity of the touch-sensitive display to a touch when the cover is detected.

11. The electronic device according to claim 10 , wherein increased sensitivity of the touch-sensitive display is maintained while the cover covers the touch-sensitive display.

12. The electronic device according to claim 10 , wherein the sensitivity is increased by decreasing a threshold value utilized to detect a touch based on a comparison to signals from touch sensors of the touch-sensitive display.

13. The electronic device according to claim 10 , wherein the sensitivity is increased by automatically increasing a drive voltage applied across electrodes of the touch-sensitive display.

14. The electronic device according to claim 10 , wherein the sensor is disposed on a housing of the electronic device.

15. The electronic device according to claim 10 , wherein the sensor comprises at least one of a magnetic sensor, a Hall effect sensor, and a switch.
