    • Composite or layered flakes (12) having a plurality of layers of different materials, which may be dielectric materials, conductive materials, or liquid crystalline materials suspended in a fluid host (14) and subjected to an electric field, provide optical effects dependent upon the angle or orientation of the flakes (12) in the applied electric field. The optical effects depend upon the composition and thickness of the layers, producing reflectance, interference, additive and/or subtractive color effects. The composition of layered flakes (12) may also be selected to enhance and/or alter the dielectric properties of flakes, whereby flake motion in an electric field is also enhanced and/or altered. Devices having a system of flakes (12) in a fluid host (14) are useful as active electro-optical displays, polarizers, filters, light modulators, and wherever controllable polarizing, reflecting and transmissive optical properties are desired.
    • 具有多层不同材料的复合或层状薄片(12),其可以是悬浮在流体主体(14)中并经受电场的电介质材料,导电材料或液晶材料,提供依赖于 在所施加的电场中的薄片(12)的角度或取向。 光学效果取决于层的组成和厚度,产生反射率,干涉,添加和/或减色效果。 也可以选择层状薄片(12)的组成以增强和/或改变薄片的介电性能,由此电场中的薄片运动也被增强和/或改变。 具有流体主体(14)中的薄片(12)系统的装置可用作有源电光显示器,偏振器,滤光器,光调制器,并且需要可控的偏振,反射和透射光学性质。
