Abstract
Embodiments described herein include a method and apparatus for capacitive sensing in input devices integrated with a display device. In one example, an input device is provided that includes a display device, a plurality of transmitter electrodes integrated with the display device, and a processing system. The plurality of transmitter electrodes include at least a first transmitter electrode and a second transmitter electrode. The first transmitter electrode includes a plurality of transmitter electrode segments. The plurality of transmitter electrode segments includes at least a first transmitter electrode segment connectable with a second transmitter electrode segment. The processing system is configured to: when operating in a first mode, simultaneously drive the first transmitter electrode segment and the second transmitter electrode segment connected as the first transmitter electrode, and when operating in a second mode, drive the first transmitter electrode segment separately from the second transmitter electrode segment.
