    • 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 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 ΔT of >57%.
    • 一种光阀膜,其形成光阀的光调制元件,所述膜由交联聚合物基质和多个液滴的液体光阀悬浮液分散在其中。 该膜具有相位比:通过下式计算的%粒子数值:矩阵/胶囊比例%凝聚粒子呃凝胶胶囊的相位⁢比率 数量在一个实施例中,光阀膜在无电力关闭状态下具有相对较低的可见光透射率,使得膜具有 T> 42%的%T。 在另一个实施例中,光阀膜在接通状态下具有相对较高的可见光透射率,使得膜的%T> 70%,&Dgr; T> 57%。
