Surface acoustic wave touch panel with interdigital transducers

摘要

A surface acoustic wave (SAW) touch panel with interdigital transducers (IDTs) includes a panel having a first edge, a second edge, a third edge and a fourth edge, a X-axis transmitting transducer, a X-axis receiving transducer, a Y-axis transmitting transducer, a Y-axis receiving transducer and a plurality of reflector structures for reflecting the surface acoustic waves generated by the X-axis transmitting transducer and the Y-axis transmitting transducer. The X-axis transmitting/receiving transducers or the Y-axis transmitting/receiving transducers includes at least one IDT.
