Abstract: Touch sensing performance can be improved using display noise correction. In some examples, a touch sensor panel in proximity to a display can capture first touch data at a first time interval and second touch data at a second time interval, different from the first-time interval. In some examples, third touch data can be generated by removing noise from the first touch data using at least a portion of the first touch data and at least a portion of the second touch data.

Abstract: Touch sensing performance can be improved using display noise correction. In some examples, a touch sensor panel in proximity to a display can capture a first touch image from a touch sensor panel concurrently with updating the display and a second touch image from the touch sensor panel concurrently with blanking the display (e.g., while the display is not updating). A composite touch image can be generated by summing a filtered first touch image and a filtered second touch image. The composite touch image can be further filtered using robust regression techniques to remove residual display noise.
