SPD FILMS AND LIGHT VALVES COMPRISING SAME |
摘要 |
<p>A film suitable for use as the light-modulating unit of an SPD light valve, the film comprising a cross-linked polymer matrix and having droplets of a liquid light valve suspension distributed in the cross-linked polymer matrix, the liquid light valve suspension comprising particles suspended in a liquid suspending medium, wherein the matrix and the droplets each have a refractive index within a range of from about 1.455 to 1.463 and wherein the refractive index of the droplet and the matrix components of the film are preferably matched as closely as possible within RI 0.005 of each other.</p> |
