Method for designing reflection stripes of an acoustic touch screen
First Claim
1. A method for designing reflection stripes of an acoustic touch screen, wherein said acoustic touch screen has at least one reflection stripe, and each reflection stripe has a plurality of reflection bars, said method comprises the steps of:
- dividing each reflection stripe of an acoustic touch screen into a plurality of groups according to an integral times wavelength of an acoustic;
according to the distance between said reflection bars increasing principle, increasing the distance between said reflection bars from rear to front; and
according to a condition of the transmission loss of a glass surface, cutting the border of said reflection bars in one group with different length.
