  • Patent number: 9367172
    Abstract: The present invention provides a method for detecting touch trace while preventing interruption of the touch traces in the presence of interfering noise, comprising: changing frequency of driving signals in response to a detection of noise; setting a plurality of lines of first sensing signal values obtained from a first sensing as a plurality of baselines; obtaining a plurality of difference values by comparing a plurality of lines of second sensing signal values obtained from a second sensing against said plurality of baselines; determining whether all said plurality of difference values are smaller than a threshold value; determining whether the flatness of said plurality of baselines is greater than a flatness threshold value if all said plurality of difference values are determined to be smaller than said threshold value; and reporting, in response to the flatness of said plurality of baselines is determined to be greater than said flatness threshold value, a first proximity or touch event, said first pr
