ABSTRACT:
An acoustic wave touch panel comprising a substrate formed of a first material. The substrate is capable of supporting an acoustic wave for propagation therein. A reflective array upon the substrate is provided for reflecting an acoustic wave to propagate in the substrate. The reflective array is formed in the substrate. An inlay is formed of a second material. The inlay is disposed in the reflective array, wherein the acoustic wave has a velocity of propagation in the second material that is slower than the velocity of propagation of the acoustic wave in the first material.
