  • Patent number: 11320934
    Abstract: Bi-phase touch scanning of a touch sensor panel can reduce interference between touch and display operations for a touch screen including a display and a touch sensor panel. The bi-phase touch scan can include concurrently driving a first plurality of touch electrodes with a first drive signal having a first phase and a second plurality of touch electrodes with a second drive signal having a second phase, different from the first phase (e.g., 180° out of phase for improved charge balancing). In some examples, the bi-phase touch scan can be locally guarded such that adjacent touch electrodes to a sensed touch electrode can be driven with the same drive signal as the sensed touch electrode. In some examples, the bi-phase pattern of driving and sensing can balance charge along an axis and/or in a localized region.
