  • SPD FILMS WITH DARKER OFF-STATE TRANSMITTANCES AND LIGHTER ON-STATE TRANSMITTANCES
    Publication number: 20130208342
    Abstract: A light valve film forming a light-modulating element of a light valve, the film comprised of a cross-linked polymer matrix with a plurality of droplets of a liquid light valve suspension distributed therein. The film has a phase ratio: % particle number value calculated by the formula: Matrix / capsule ? ? ratio % ? ? particles ? ? in ? ? the ? ? capsule = Phase ? ? ratio ? : ? ? % ? ? particle ? ? number In one embodiment the light valve film has a relatively low visible transmittance in the unpowered Off state such that the film has a % T of <0.05 and a ?T of >42%. In another embodiment the light valve film has a relatively high visible transmittance in the On state such that the film has a % T of >70% and a ?T of >57%.
