发明名称 MODULATED POWER SUPPLY FOR REDUCED PARASITIC CAPACITANCE
摘要 <p>An input device comprising a display device having an integrated capacitive sensing device. The input device includes a plurality of sensor electrodes a plurality of display electrodes, a modulated power supply configured to provide a modulated reference signal, and a processing system. The processing system includes a sensor module configured to drive a plurality of sensor electrodes with a modulated capacitive sensing signal that is based on the modulated reference signal for capacitive sensing during a first time period. The processing system also includes a display driver module configured to drive a plurality of display electrodes of a display device with modulated signals based on the modulated reference signal during the first time period. The modulated signals cause voltage between the plurality of display electrodes and the plurality of sensor electrodes to remain substantially constant.</p>
