SYSTEMS AND METHODS FOR REDUCING POWER CONSUMPTION IN A TOUCH SENSOR DISPLAY
First Claim
1. An information handling system comprising:
- a processor;
a user interface comprising;
a display;
a touch sensor overlaid on the display and configured to detect tactile touches on the user interface; and
a touch sensor controller communicatively interfaced between the touch sensor and the processor and configured to;
translate signals received from the touch sensor and communicate such translated signals to the processor; and
control a rate of sampling of tactile touches on the touch sensor; and
a proximity sensor communicatively coupled to the processor and configured to detect a human finger or stylus proximate to the touch sensor;
wherein the processor is configured to;
based on information communicated to the processor from the touch sensor and information communicated to the processor from the proximity sensor, determine a desired rate of sampling; and
cause the touch sensor controller to control the rate of sampling such that the touch sensor operates at the desired rate of sampling.

Abstract
In accordance with embodiments of the present disclosure, a method may include receiving information communicated from a touch sensor controller configured to translate signals received from the touch sensor and control a rate of sampling of tactile touches on the touch sensor. The method may also include receiving information communicated from a proximity sensor configured to detect a human finger or stylus proximate to the touch sensor. The method may further include, based on the information communicated from the touch sensor controller and information communicated from the proximity sensor, determining a desired rate of sampling. The method may additionally include causing the touch sensor controller to control the rate of sampling such that the touch sensor operates at the desired rate of sampling.
