Abstract: Embodiments described herein include a display device having a capacitive sensing device, a processing system and a method for detecting presence of an input object using a capacitive sensing device. In one embodiment, the display device includes a plurality of sensor electrodes arranged in a matrix. The processing system performs absolute capacitive sensing with the matrix of sensor electrodes. When an area of interest is detected using the absolute capacitive sensing techniques, the processing system performs targeted transcapacitance sensing using a selected subset of the sensor electrodes in the area of interest.

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.

Abstract: A method and apparatus for operating an input device having a touch sensor and associated display device is discussed. While performing touch sensing, inactive transmitter electrodes of the touch sensor are electrically floated, and one or more source lines from the display device are operated to achieve shielding against interference, such as that coming from a backlight underneath the touch sensor.
