Abstract: Disclosed are a touch sensor and a method for determining a position, in three dimensions, of a conducting object with respect to a display device of the touch sensor. The determination of the position of the conducting object is done by performing at least one measurement of the capacitive load of at least one display electrode of the display wherein the measurement is performed by charging the capacitive load of the at least one display electrode by a predefined signal. The charging results in at least one charging curve, from which the capacitive load of the at least one display electrode may be determined by measuring the rise time of the charging curve of the charging, and calculating the position of the at least one conducting object, with respect to said display device based on the determined capacitive load.
