Abstract: Embodiments of the present invention generally provide a processing system for a display device having an integrated sensing device. The processing system includes a driver module coupled to a plurality of source lines and a plurality of transmitter electrodes. Each transmitter electrode includes one or more common electrodes configured for display updating and input sensing. The driver module is configured for selecting a first display line for display updating and driving the sources lines with first display update signals to update the first display line. The drive module is further configured for driving a first transmitter electrode of the plurality of transmitter electrodes for input sensing during a non-display update period and driving the source lines with restore signals during a restart period. The processing system further includes a receiver module coupled to a plurality of receiver electrodes and configured for receiving resulting signals with the receiver electrodes.

Abstract: Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving common electrodes corresponding to pixels in a display line. In general, the input devices drive each electrode until each display line (and each pixel) of a display frame is updated. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a proximity sensing area. To do this, the input device may interleave periods of capacitive sensing between periods of updating the display based on a display frame. For example, the input device may update the first half of display lines of the display screen, pause display updating, perform capacitive sensing, and finish updating the rest of the display lines. Further still, the input device may use common electrodes for both updating the display and performing capacitive sensing.
