Abstract: A controller for a touch-screen sensor is described. The controller comprises a voltage generator for generating a first voltage signal and at least one output for outputting the first voltage signal such that the first voltage is applied across a resistive layer of the sensor in a first direction (e.g. X direction). The controller further comprises an input for receiving a second voltage signal representing the voltage on the resistive layer measured at a touch position by a measuring electrode of the sensor when the sensor is touched. A processor determines the co-ordinate in the first direction (e.g. X co-ordinate) of the touch position using the second voltage signal received during a first measuring period. Specifically, the co-ordinate is determined by determining the attenuation of the first voltage signal in the second voltage signal.
