Touch Sensing With A Common Driver

摘要

In one embodiment, an apparatus includes a touch sensor including drive electrodes. The apparatus also includes sense electrodes arranged along a first axis and a second axis. The first and second axes are substantially perpendicular to each other. The apparatus also includes one or more computer-readable non-transitory storage media coupled to the touch sensor that embody logic that drives all the drive electrodes substantially simultaneously with a common drive signal.
