REDUCING TOUCH SENSOR PANEL POWER CONSUMPTION
First Claim
1. A method of operating a touch screen, the method comprising:
- determining a number of concurrent modes of operation to operate the touch screen,for each mode of operation;
determining one or more portions of the touch screen having a respective touch accuracy, andoperating the one or more portions at a touch frequency associated with the respective touch accuracy; and
wherein;
each mode of operation and each touch frequency are different with respect to other modes of operation when the touch screen operates in a plurality of concurrent modes of operation.

Abstract
Reducing power consumption in a touch screen. In some examples, a first level of touch accuracy can be determined, and a first portion of the touch screen can be operated in a first mode corresponding to the first level of touch accuracy. In some examples, a second level of touch accuracy can be determined, and a second portion of the touch screen can be operated in a second mode corresponding to the second level of touch accuracy. The first and/or second levels of touch accuracy can be determined based on an application running on a device including the touch screen and/or a user interface displayed on the touch screen. In some examples, in the first and/or second modes, the respective portions of the touch screen can transition between a touch sensing phase and a display phase at different transition frequencies and/or can sense touch at different ratios of touch sensors.
