Abstract: Embodiments of the present disclosure provide a technique for input sensing using an input device having a display device with an integrated sensing device. Input sensing is performed over a long sensing interval to attain narrow-band filtering, and is temporarily suspended for short intervals (within the long sensing interval) to refresh the row selection logic of the display device.

Abstract: Techniques for varying aggregate area of a sensor electrode used for capacitive sensing. Sensor electrodes are driven for capacitive sensing. Resulting signals are received from the sensor electrodes. Based on signal strengths of the resulting signals, aggregate area of the sensor electrodes may be varied. The aggregate area of the sensor electrodes may be varied by connecting or disconnecting segments of the sensor electrodes from a sensor module that drives the sensor electrodes for capacitive sensing. The ability to vary the aggregate area of the sensor electrodes expands the overall dynamic range of a receiver module coupled to the sensor electrodes.
