An input-display device includes a display screen disposed on a display substrate, the display screen including a multitude of display pixels. The input-display device further includes a multitude of capacitive sensing electrodes for capacitive sensing in a sensing region of the display screen. The input-display device also includes a source driver circuit configured to generate a data voltage for driving a pixel circuit associated with one display pixel of the multitude of display pixels and determine a timing for a compensatory modulation of the data voltage. The timing is determined using a sensing waveform of the capacitive sensing. The source driver circuit is also configured to determine an amplitude of the compensatory modulation, generate a modulated data voltage by applying the compensatory modulation to the data voltage, and drive the pixel circuit using the modulated data voltage.
