A method for fabricating a metallic wire mesh touch sensor with reduced visibility. A metallic wire mesh is formed on a transparent substrate such that the surface of the metallic wires is roughened or textured, so as to cause high scattering of incident light, thereby minimizing specularly reflected light towards the user. The metal lines are formed over patterned catalytic photoresist. The rough or textured surface of the metallic wires is achieved by roughening or texturing the catalytic photoresist, by selecting parameters of electronless plating of copper, or both. An RMS surface roughness of about 50 nm would scatter approximately 70% of incident cyan light incident at 30&#xb0;.

Reduced visibility conductive micro mesh touch sensor

Touchscreen having a display device and a touch sensor adhered to the display device via optically clear adhesive; wherein the touch sensor comprises a transparent substrate; a top metal mesh divided into channels; a bottom metal mesh divided into channels; each of the top and bottom metal meshes having line spacing calculated to avoid first order moir&#xe9; patterns and then the intersections of the lines randomized to avoid secondary order moir&#xe9; patterns.
