摘要: In a method of capacitive sensing using an integrated capacitive sensor device and display device, a transmitter signal is transmitted with a combination electrode of the integrated capacitive sensor device and display device. The combination electrode is configured for both capacitive sensing and display updating. The transmitter signal transitions at least twice during a non-display update time period associated with row update of the display device. A display of the display device is updated during an update time period. A resulting signal is received with a receiver electrode of the integrated capacitive sensor device and display device during the non-display update time period. The resulting signal corresponds to the transmitter signal.

摘要: In a method of interference avoidance for a capacitive sensor device, a transmitter signal is transmitted with a transmitter electrode of the capacitive sensor device. A resulting signal is received with a receiver electrode of the capacitive sensor device. The resulting signal corresponds to the transmitter signal. A first demodulated output is acquired by demodulating the resulting signal in a first way. A second demodulated output is acquired by demodulating the resulting signal in a second way, where the second way and the first way differ. A shift is made from using the first demodulated output for determining positional information to using the second demodulated output for determining positional information. The shift is based at least in part upon an amount of interference.
