Abstract
Adaptive power adjustment for a touch screen. A first level of voltage can be selectively applied to at least a first portion of a plurality of touch sensors of the touchscreen. A second level of voltage can be selectively applied to at least a second portion of the plurality of touch sensors, wherein the second level of voltage is lower than the first level of voltage and greater than 0 volts, or the second portion of the plurality of touch sensors can be deactivated.

10. A method of implementing voltage adjustment for a touchscreen, comprising:
-
identifying a user interface object visually presented by the touchscreen; responsive to identifying the user interface object visually presented on the touchscreen; selectively activating a first plurality of touch sensors configured to detect a touch event in a first region of the touchscreen where the user interface object is visually presented; and responsive to identifying the user interface object visually presented on the touchscreen, selectively deactivating a second plurality of touch sensors configured to detect a touch event in a second region of the touchscreen where the user interface object is not visually presented. - View Dependent Claims (11)
