Abstract
Embodiments described herein include a method, processing system, and input device having a display device with an integrated sensing device. The method comprises selecting, using first gate driver circuitry, a first subset of a first plurality of gate electrodes of the display device for performing display updating during a first period. The method further comprises selecting, using second gate driver circuitry, a first subset of a second plurality of gate electrodes of the display device for display updating during a second period. The method further comprises operating, during a third period between the first and second periods, at least a first sensor electrode of a plurality of sensor electrodes for capacitive sensing.
