Apparatus and method of adjusting power mode of a display of a device

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 percentage of an area of the touch surface of the display being covered by the set of contact signals, wherein the contact signature corresponds to one or more mappings of areas of contact of an object with the touch surface of the display;
• 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.

A non-transitory computer-readable storage medium storing computer-executable instructions executable by a processor for adjusting a power mode of a display of a device, comprising:

• instructions for determining 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 percentage of an area of the touch surface of the display being covered by the set of contact signals, wherein the contact signature corresponds to one or more mappings of areas of contact of an object with the touch surface of the display;
• 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.
