Touchscreen panel frequency response determination

Apparatuses and methods of frequency-response calculation are described. One method measures a charge on an electrode of a touch panel by a capacitance-sensing circuit of a processing device. The processing device measures a frequency response of the touch panel and selects an operating frequency of...

Summary:Apparatuses and methods of frequency-response calculation are described. One method measures a charge on an electrode of a touch panel by a capacitance-sensing circuit of a processing device. The processing device measures a frequency response of the touch panel and selects an operating frequency of the touch panel in view of the frequency response.
