Abstract
A multifunctional device layer may include a lightguide substrate having an optically patterned surface and an opposing non-patterned surface. The non-patterned surface of the lightguide substrate is coated with a first material having a first refractive index and the patterned surface is coated with a second material having a second refractive index. The first refractive index may be lower than the second refractive index and each may be lower than a refractive index of the lightguide substrate. A touch sensor may be formed on the coated non-patterned surface of the lightguide substrate, the coated patterned surface, or on an interstitial layer deposited on the coated non-patterned surface or the coated patterned surface. An anti-glare/anti-reflective coating potentially having ultraviolet (UV) absorption properties may be applied to the touch sensor.
