1. A method for fabrication on an interferometric modulator system comprising:

  • providing a light guide element which includes a plurality of scattering elements located therein;

    providing an interferometric modulator disposed with respect to the light guide to receive light therefrom; and

    applying ultra-violet (UV) light to at least a portion of a coating on at least a portion of said scattering elements, thereby masking at least a portion of said scattering elements,wherein the applying step comprises;

    activating the coating on a first side by providing UV light to the first side at a first wavelength; and

    deactivating the coating on a second side substantially opposite the first side to maintain the optical scattering character of the scattering elements.
