APPARATUS AND METHOD OF ADJUSTING POWER MODE OF A DISPLAY OF A DEVICE
First Claim
1. A method of adjusting a power mode of a display of a device, comprising:
- detecting a set of contact signals on a touch surface of the device;
determining whether the set of contact signals correspond to a contact signature associated with an in-use state of the display based on one or more of a signal strength or a duration corresponding to the set of contact signals, and based on a number of contacts of an object with the touch surface of the display or a movement of the contacts of the object, wherein the contact signature corresponds to one or more mappings of areas of the contacts of the object;
transitioning the power mode of the display to a power saving mode in response to determining that the set of contact signals do not correspond to the contact signature associated with the in-use state of the display; and
retaining the power mode of the display in a current power mode in response to determining that the set of contact signals correspond to the contact signature associated with the in-use state of the display.

Abstract
Methods and devices for adjusting a power mode of a display are disclosed. An example method includes detecting a set of contact signals on a surface of the device and determining whether the set of contact signals correspond to a contact signature associated with an in-use state of the display. The example method further includes transitioning the power mode of the display to a power saving mode in response to determining that the set of contact signals do not correspond to the contact signature associated with the in-use state of the display, and retaining the power mode of the display in a current power mode in response to determining that the set of contact signals correspond to the contact signature associated with the in-use state of the display. An additional example method may further include detecting whether a proximity sensor at the device is occluded prior to the transition.

8. An apparatus for adjusting a power mode of a display of a device, comprising:
-
a memory; and a processor in communication with the memory, wherein the processor is configured to; detect a set of contact signals on a touch surface of the device; determine whether the set of contact signals correspond to a contact signature associated with an in-use state of the display based on one or more of a signal strength or a duration corresponding to the set of contact signals, and based on a number of contacts of an object with the touch surface of the display or a movement of the contacts of the object, wherein the contact signature corresponds to one or more mappings of areas of the contacts of the object; transition the power mode of the display to a power saving mode in response to determining that the set of contact signals do not correspond to the contact signature associated with the in-use state of the display; and retain the power mode of the display in a current power mode in response to determining that the set of contact signals correspond to the contact signature associated with the in-use state of the display. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium storing computer-executable instructions executable by a processor for adjusting a power mode of a display of a device, comprising:
-
instructions for detecting a set of contact signals on a touch surface of the device; instructions for determining whether the set of contact signals correspond to a contact signature associated with an in-use state of the display based on one or more of a signal strength or a duration corresponding to the set of contact signals, and based on a number of contacts of an object with the touch surface of the display or a movement of the contacts of the object, wherein the contact signature corresponds to one or more mappings of areas of the contacts of the object; instructions for transitioning the power mode of the display to a power saving mode in response to determining that the set of contact signals do not correspond to the contact signature associated with the in-use state of the display; and instructions for retaining the power mode of the display in a current power mode in response to determining that the set of contact signals correspond to the contact signature associated with the in-use state of the display. - View Dependent Claims (16, 17, 18, 19, 20)
