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.

Abstract: Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving electrodes corresponding to pixels in a display line. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a touch area. To do this, the input device uses common electrodes for both updating the display and performing capacitive sensing, and interleaves periods of capacitive sensing between periods of updating the display lines (and pixels) based on a display frame. To avoid noise and mitigate interference during capacitive sensing, the input device may change the capacitive frame rate relative to the display frame rate based on measurements of interference. The changed capacitive frame rate may result in re-timed periods of capacitive sensing based on each display frame.

Abstract: An input device may include various sensor electrodes that define various sensor pixels. The input device may further include a processing system coupled to the sensor electrodes. The processing system may obtain a first resulting signal and a second resulting signal from the sensor electrodes. The processing system may determine, using the first resulting signal, an in-phase estimate of a phase delay at a sensor pixel among the sensor pixels. The processing system may determine, using the second resulting signal, a quadrature estimate of the phase delay at the sensor pixel. The processing system may determine, based at least in part on the in-phase estimate and the quadrature estimate, a phase baseline estimate of the sensor pixels.
