摘要： Described is a sensing device of a surface acoustic wave (SAW) touch panel having a new reflector columns and rows arrangement. As compared to the conventional design in the art where each of the reflector columns and rows are arranged from thinness to thickness, each of the arrangements of the reflector columns and rows herein is composed of a plurality of uniformly disposed reflectors having several sub-reflectors isolated with a gap or gaps. In this manner, a vibration wave transmitted through each of the reflector columns or rows can be reflected and then collected at a target transducer in an uniform pattern with respect to each portion of each of the reflecting columns and rows, thereby avoiding the problem encountered in the prior art.
