Abstract
Light reflection from a metal mesh touch sensor is reduced or prevented by encasing the metal lines with a passivation coating and including non-reflective nanoparticles in the patterning photoresist. The photoresist is mixed with catalytic nanoparticles wherein the nanoparticles are formed to minimize light reflection. The nanoparticles may be carbon coated metallic particles, or uncoated palladium nanoparticles. Also, a standoff photoresist layer may be included between the substrate and the photoresist composition to prevent reflection from the edges of the metallic lines.
