  • Touchpad with interleaved traces
    Patent number: 6147680
    Abstract: A unique layout with a matrix of traces having at least traces in one direction provided with portions which are interleaved with portions of adjacent traces. Unlike the prior art zigzag pattern, the extensions of the traces of the present invention are actually interleaved, so that they overlap with portions of the adjacent trace. Thus, a finger moving from one trace to the next will contact the interleaved portions of the adjacent trace before it leaves the interleaved portions of the first trace.
