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.

摘要： A processing system for a capacitive touch screen comprises sensor circuitry and control logic. The sensor circuitry is configured to communicatively couple with sensor electrodes of the capacitive touch screen. The control logic is configured to operate the capacitive touch screen in a first mode comprising interference sensing at a first level and input object sensing. The control logic is also configured to operate the capacitive touch screen in a second mode instead of the first mode in response to: interference measured in the first mode meeting an interference condition; and a determination that input is in a sensing region of the capacitive touch screen. Operating in the first mode, interference sensing is performed during a non-display update time. Operating in the second mode, interference sensing with the capacitive touch screen is either not performed or is performed at a second level, lower in fidelity than the first level.
