Abstract: A capacitive touch panel includes first electrodes extending in first direction and second electrodes extending in a second (intersecting) direction. The first electrodes include parallel extending transmit first electrodes and receive first electrodes that are interleaved with each other. The second electrodes include parallel extending transmit second electrodes and receive second electrodes that are interleaved with each other. Transmit circuitry is coupled to the transmit first electrodes and transmit second electrodes. Receive circuitry coupled to the receive first electrodes and receive second electrodes. Processing circuitry controls activation of the transmit and receive circuitry in a manner which supports the making of adjacent line capacitance measurements and intersecting line capacitance measurements. The capacitance measurements are processed to identify and determine location of touches made on or near the capacitive touch panel.
