摘要： Embodiments described herein include a method and apparatus for capacitive sensing in input devices integrated with a display device. In one embodiment, a processing system for a display device comprising an integrated capacitive sensing device is provided that includes a display driver module, a transmitter module, and a receiver module. The display driver and transmitter modules are configured to operate in a display update mode and a sleep mode. The receiver module is configured to, while operating in a doze mode, communicate with and trigger the transmitter module to enter the active sensing mode while the display driver module remains in the sleep mode when presence of an object is detected based on the resulting signals.

摘要： 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, while also using the display screen as a touch area for capacitive sensing. 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 switch which windows of time in a display frame are used as capacitive sensing periods based on measurements of interference.
