Abstract

An electrode arrangement has a matrix with rows and columns of capacitive touch sensors arranged in a single layer, wherein each touch sensor has a first electrode and an associated second electrode, wherein the first electrodes in each row of the matrix are connected and the second electrodes in each column of the matrix are connected, and wherein the electrode arrangement further has a capacitive coupling operable to feed an alternating transmission signal only to the top and bottom row of connected first electrodes and to the most left and most right column of connected second electrodes.
