Abstract
A touch-sensitive display for an electronic device may include a touch sensor comprising a low birefringence substrate, ultraviolet (UV) stabilizers, and a metal mesh disposed on at least a portion of the low birefringence substrate. The low birefringence characteristic of the touch sensor substrate causes the touch sensor to exhibit low haze, high transmittance, and substantially no color, which provides improved optical properties over conventional touch sensor substrate materials used with metal mesh film. In some embodiments, the retardation value of the touch sensor substrate may be no greater than about 15 nanometers (nm). Additionally, the UV stabilizers prevent the substrate from yellowing and becoming brittle from exposure to UV radiation.
