Abstract
Embodiments of this disclosure provide a touch device, a touch system and a control method thereof. The touch device includes: a touch screen including: a plurality of touch electrodes, and a plurality of switch circuits corresponding to the plurality of touch electrodes respectively; and a drive chip bound and connected with the touch screen. The touch electrodes are coupled to the drive chip through the corresponding switch circuits. The drive chip is configured to: determine that the touch screen is contacted by an interference object and determine an interference area, according to capacitance values of the touch electrodes during a time period when a stylus is interacting with the touch screen, and disconnect touch electrodes in the interference area from the drive chip through corresponding switch circuits.
