Abstract
A touch screen includes a plurality of single-layer ITO bars having a substantially rectangular shape and arranged in parallel to each other in order to detect touches on the touch screen. The location of a touch on the touch screen in the direction along an ITO bar is determined by applying a signal on one end of the ITO bar and measuring the change in the amplitude and the delay of the signal on the opposite end of the ITO bar. Such application and measurement of the signal can be repeated with the application of the signal occurring on the opposite end of the ITO bar and the measurement of the signal occurring on said one end of the ITO bar, in order to enhance the accuracy of the measurement.
