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.
