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.

Claim (Index 1):
A device incorporating a capacitive touch sensor, the device comprising:\n a touch panel having on an upper side a touch surface and on a lower side an internal surface, the touch panel being made of a dielectric material and having a thickness, h, of less than or equal to 400 micrometers; drive and sense touch sensor electrodes, X and Y, arranged under the touch panel so as to cross each other at crossing points to form a two-dimensional array of nodes, the X and Y electrodes of each node comprising mutually co-extending X and Y electrode portions of respective widths, Wx and Wy, that are separated by a gap, G, suitable for making a mutual capacitance measurement of a touching object impinging on the touch surface, wherein the width, Wy, of the co-extending Y electrode portions plus the gap, G, between co-extending X and Y electrode portions is less than or equal to 4 times the thickness, h, of the touch panel.
