摘要:
Embodiments of the present invention generally provide an integrated input device. The integrated input device includes a plurality of sensor electrode sets including a plurality of common electrode sets, a plurality of gate electrodes, and a gate selector. A processing system is configured to drive the sensor electrode sets for capacitive sensing during a plurality of sensing periods and update display lines by driving the common electrode sets during display update periods. A sensor electrode of a first sensor electrode set that is driven last during a first sensing period and a sensor electrode of a second sensor electrode set that is driven first during a second sensing period are spatially non-sequential sensor electrodes. The first display update period, second display update period, and third display update period are non-consecutive and non-overlapping with the first sensing period, the second sensing period, and the third display update period, respectively.
