In some embodiments, indicia from the at least three distinct sensor electrodes associated with at least three sensor electrode elements comprising the capacitive button are received, the indicia indicative of interaction of an input object with the at least three distinct sensor electrodes.

摘要： Embodiments for a capacitive sensing apparatus with attenuated electrical interference across a plurality of routing traces are provided. One embodiment forms a first sensor electrode on a substrate. In addition, a first routing trace is formed on the substrate, the first routing trace coupled with the first sensor electrode. One embodiment additionally forms a second sensor electrode on the substrate. A second routing trace differing in length from the first routing trace is also formed on the substrate, the second routing trace coupled with the second sensor electrode. To attenuate electrical interference, the second routing trace is formed having an approximately equal RC time constant characteristic as the first routing trace.

摘要： An input device is provided with improved electrostatic discharge protection. Specifically, the input device includes a plurality of capacitive sensing electrodes configured for object detection. An electrostatic discharge (ESD) shunt is disposed near the capacitive sensing electrodes and configured to provide ESD protection to the capacitive sensing electrodes. The input device also includes an extended-proximity capacitive sensing electrode configured to for object detection of relatively distant objects. The ESD shunt has an associated first resistance, and the extended-proximity capacitive sensing electrode has an associated second resistance. The second resistance is greater than the first resistance such that an electrostatic discharge at a first exposed location would be attracted to the ESD shunt via a first potential discharge path instead of being attracted to the extended-proximity capacitive sensing electrode via a second potential discharge path, where the first discharge path is longer than the second discharge path.

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.
