Abstract:
A touch screen includes a display layer for displaying information. An inductor grid includes a plurality of inductive elements arranged on a single layer. At least one switch matrix selects an inductive element in response to the selection signal. A driver generates the selection signal, drives the selected inductive element to detect a touch object in proximity to the selected inductive element and generates touch screen data in response thereto.
