Abstract
Methods, Integrated Circuits (IC) and computer programs for decoding contacts in a digital resistive screen overlay (DRSO) are presented. The method includes coupling in succession columns of the DRSO to a first voltage while floating a remainder of the columns. Further, the method includes the operation of checking during a sampling time if each row of the DRSO is connected through closed switches in the DRSO to the column coupled to the first voltage. The sampling time is configured such that the sampling time for a given row is previous to the arrival time of a signal that started with the coupling of a column and that propagated to the given row through more than one closed switch in the DRSO.
