  • Patent number: 10423285
    Abstract: In a capacitive touch sensor device, to avoid floating touches causing signal inversion in mutual capacitance measurements, an electrode pattern is used of the type in which the mutual capacitance arises primarily from co-extending electrode portions of the drive and sense electrodes separated by a gap G. The pattern is dimensioned such that the sum of the gap G between co-extending drive and sense electrode portions and the widths Wy of the sense electrodes is made sufficiently small to avoid signal inversion. Namely, the width, Wy, plus the gap, G, is made less than or equal to one of: 4, 3 or 2 times the distance from the touch sensor electrodes to the touch surface, this distance being the touch panel thickness, h.
