Abstract

A method for designing reflection stripes of an acoustic touch screen, comprising: dividing a 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 bar 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.
