摘要:
A capacitive sense array configured to improve accuracy in detecting a presence of a conductive object is described. In one embodiment the capacitive sense array includes a first set of sense elements including a plurality of sub-sections and a second set of sense elements including a plurality of sub-sections such that the plurality of sub-sections of one sense element of the first set straddle at least one of the plurality of sub-sections of at least two of the sense elements of the second set. The straddle as defined in the present invention includes shifting and interleaving sub-section of one sense element with the sub-sections of at least two sense elements adjacent to the one sense element.
