    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.
