Abstract: 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.
