  • MULTI-SCAN TOUCH SENSING SYSTEM AND METHOD
    Publication number: 20230205365
    Abstract: In some examples, a touch screen can perform a first touch scan to obtain first touch data and a second touch scan to obtain second touch data. The touch data resulting from the second touch scan may exclude respective noise (e.g., display-to-touch crosstalk (DTX) noise) or may include a reduced amount of the respective noise. In some examples, the electronic device can subtract the second touch data from the first touch data to obtain an estimate of the noise in the first touch data. In some examples, this noise estimate can be subtracted from the first touch data and an action can be performed based on the first touch data with the noise estimate removed.
