System and method for reducing display interference

A method for reducing effects of interference, the method comprising:

• acquiring, by a sensor driver, resulting signals via a plurality of sensor electrodes, wherein the plurality of sensor electrodes is disposed over a display panel, and wherein the resulting signals include effects of display-related interference;
• receiving, by the sensor driver, a display signal from a display driver;
• generating, by the sensor driver, an interference metric based on the display signal, the interference metric corresponding to an amount of display interference;
• and
• after acquiring, via the plurality of sensor electrodes, the resulting signals which include the effects of the display-related interference, adjusting, by the sensor driver, the acquired resulting signals using the interference metric to reduce the effects of the display-related interference included in the acquired resulting signals.

A processing system for an input device, comprising:

• a display driver configured to drive a plurality of display electrodes of a display panel;
• and
• a sensor driver communicatively coupled to a plurality of sensor electrodes and the display driver, wherein the sensor driver is configured to:
• acquire resulting signals via the plurality of sensor electrodes, wherein the resulting signals include effects of display-related interference;
• receive a display signal from the display driver;
• generate an interference metric based on the display signal, the interference metric corresponding to an amount of display interference;
• and
• after acquiring, via the plurality of sensor electrodes, the resulting signals which include the effects of the display-related interference, adjust the acquired resulting signals using the interference metric to reduce the effects of the display-related interference included in the acquired resulting signals.
