Abstract:
A touch sensing device including digital filter is provided. The touch sensing device includes a touch panel and a touch sensor configured to sensing a touch through the touch panel. The touch sensor includes a plurality of sensing units connected to the touch panel through a plurality of sensing lines. Each of the plurality of sensing units includes a digital filter configured to generate a valid filtered value at a time and invalid filtered value at other times by performing an operation on a plurality of input digital samples and a plurality of filter coefficients.
