Abstract:
1. A method of making a PSCT-based panel comprising the steps of: (a) combining within a PSCT material mixture, liquid crystal (LC) material and at least two different types of monomer referred to as type-A monomer and type-B monomer, (b) depositing said PSCT material mixture between a pair of substrates and arranging said substrates so that said substrates are substantially parallel and result in a panel-like structure; and (c) polymerizing said type A and type B monomers so as to produce a PSCT layer between said pair of substrates having a substantially reduced level of haze when said PSCT-based panel is operated in its light transmission state, due to a matching of the indices of refraction of said liquid crystal material and said type-A monomer, and having high uniformity of optical characteristics across the surface of said panel due to the matching of viscosity characteristics of said liquid crystal material and said type-A and type-B monomers during steps (a) and (b) and prior to step (c).
