ABSTRACT:
A PDLC modulator is fabricated using at least one of a selection of specially-formulated UV curable organic hard coatings as a protective layer on the exposed side of polyester (Mylar) film. The hard coatings of various related types show good adhesion on a polyester film substrate, superior hardness and toughness, and have a slippery top surface, which minimizes unnecessary wear. The coating as applied on the modulator surface significantly reduces scratch damage on modulators caused by unexpected particles on the panels under test. In addition, the slip surface will reduce stickiness to particles and therefore also reduce the possibility of panel damage.
