Reducing touch sensor panel power consumption
First Claim
1. A method comprising:
- operating a touch screen in at least one of a plurality of modes, the plurality of modes including;
a first mode includes a first level of touch accuracy, a first touch sensing phase, and a first display phase, the first display phase having a first duration of time, anda second mode includes a second level of touch accuracy, a second touch sensing phase, and a second display phase, the second display phase having a second duration of time, different than the first duration of time,wherein a duration of the first mode is different from a duration of the second mode;
anddynamically changing the mode based on one or more applications running on a device, the device including the touch screen,wherein the one or more applications include a first application associated with the first mode and a second application associated with the second mode.

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.
