摘要：Embodiments of the invention generally provide an input device with displayscreens that periodically update (refresh) the screen by selectively driving commonelectrodes 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. Inaddition to updating the display, the input device may perform capacitive sensing usingthe display screen as a proximity sensing area. To do this, the input device may interleaveperiods of capacitive sensing between periods of updating the display based on a displayframe. For example, the input device may update the first half of display lines of thedisplay screen, pause display updating, perform capacitive sensing, and finish updatingthe rest of the display lines. Further still, the input device may use common electrodesfor both updating the display and performing capacitive sensing.
