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.

摘要： Embodiments of the invention generally provide a method and system that is able to minimize or remove the affect of substantially non-random electrical interference on an input device's ability to reliably and accurately sense the position of an object. In one embodiment, the input device is configured to systematically correct for a cyclic variation in the electromagnetic interference (EMI) generated by components within the electronic system, such as interference generated by the process of refreshing or updating an image on a display module that affects the capacitive sensing measurements acquired from a plurality of capacitive sensing elements. However, in some embodiments of the invention, the performance of an input device is improved by reducing the affect that external interference generated outside of the electronic system have on the position sensing data acquired by the input device.

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： A capacitive input device includes first and second pluralities of sensor electrodes disposed in a first region of a substrate. The first and second pluralities of sensor electrodes are substantially orthogonal to one another. The first region is configured to overlap a display screen. At least one routing trace is disposed in a second region of the substrate and is ohmically coupled to a sensor electrode of one of the first and second pluralities of sensor electrodes and also to a processing system. The second region comprises a non-display screen overlapping portion of the substrate. A compensation trace is disposed in the second region and ohmically coupled to the processing system. The compensation trace has substantially the same length as and is substantially parallel and proximate to the at least one routing trace. The compensation trace is not ohmically coupled to any sensor electrode located in the first region.

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.
