An improved process for making a light valve includes cross-linking and curing an SPD light valve film carried by a substrate while the film is uncovered and then laminating a second substrate to the uncovered surface of the cured SPD light valve film.

Light modulating film of improved UV stability for a light valve

A method of making crystals of a light-polarizing material useful in a liquid light valve suspension with the addition of controlled amounts of water relative to the amount of reactants used in making the particles of the light-polarizing material.

Method of making light-polarizing particles

Light valve suspensions and light valve films are provided with a UV absorber.

Light valve suspensions and films containing UV absorbers and light

A film suitable for use as the light modulating unit of a light valve comprises a cross-linked polymer matrix having droplets of a liquid light valve suspension distributed in the cross-linked polymer matrix, and a light valve comprising such a film.

Light modulating film of improved clarity for a light valve

Light valve employing a film comprising an encapsulated liquid

A light valve suspension contains a trialkyl trimellitate and/or trimesate and is used as such as the light modulating element of a light valve or droplets thereof are distributed in a light valve film used as the light modulating element of a light valve.

Light valve suspensions containing a trimellitate or trimesate and light

Light-polarizing materials, and uses thereof in liquid suspensions, set suspensions and light valves.
