A capacitive touch sensor has at least a sensing column (410) comprising a plurality of sensing elements (420a-420g). The touch sensor comprises a substrate (10), and a conductive layer (11) disposed over the substrate. The sensing column comprises n first electrodes (D1 - D7), wherein n ≧ 2, and at least a second electrode (Sj). The first electrodes and the second electrode are defined in the conductive layer and extend generally parallel to a first direction. The first electrodes comprise a plurality of first electrode unit areas (440) disposed along the first direction and electrically connected with one another and to a voltage supply line by conductive tracks defined in the conductive layer. The sensing elements (420a-420g) extend generally in a second direction crossed with the first direction, each sensing element of the sensing column including a respective first electrode unit area of at least two of the first electrodes of the sensing column and a portion of the second electrode of the sensing column. |
