Abstract: A method for capacitive sensing includes acquiring a mutual capacitive measurement including effects of sensing signals of a sensing region, and acquiring an absolute capacitive measurement including effects of the sensing signals. The method further includes performing a comparison of the mutual capacitive measurement and the absolute capacitive measurement, and detecting a presence of an input object proximate to a side surface of an input device based on the comparison. The side surface is at least substantially orthogonal to the sensing region on the input device. The method further includes reporting the presence of the input object.

Abstract: An electrode matrix that is used for capacitive sensing may be integrated into a display panel of an input device. In one embodiment, source drivers may be mounted on the display panel which drive the display signals and capacitive sensing signals into the display panel. In one embodiment, the capacitive sensing signals may be routed on wires or lines that are interleaved on the same layer as the source lines used for setting a voltage on the pixels in the display panel during display updating. Using the interleaved wires, the source drivers may drive the capacitive sensing signals in parallel to a plurality of the electrodes in the matrix in a predefined pattern that spans one or more touch cycles.

Abstract: 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.
