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.
