Abstract
Multi-layered paint on a border of a surface acoustic wave touch device may reduce attenuation. The touch substrate has a front surface and a back surface where the front surface has a touch region. Multi-layered paint is formed on the back surface to form a border along the touch substrate. The multi-layered paint includes a minor layer and a color layer. The surface acoustic waves propagate over at least a portion of the border region such that the surface acoustic waves propagate on the multi-layered paint without excessive wave attenuation.
