Abstract
In a capacitive touch sensor device, to avoid floating touches causing signal inversion in mutual capacitance measurements, a segmented conductive layer of conductive material is embedded in the touch panel. The segmented conductive layer comprises a plurality of segments of the conductive material which are separated by gaps. The segmented conductive layer effectively pre-loads the mutual capacitance of the touch sensor to the same or similar level of that of a floating touch of the maximum size for which it is desired to avoid signal inversion.
