US Patent 7758773 - Nanocrystal modifiers for LCDs


This patent from Kent State Universiy teaches how doping liquid crystal films with ferroelectric nanoparticles can improve the properties of LCDs. Claim 1 reads:

1. A liquid crystal material comprising a suspension of inorganic anisotropic ferroelectric nanoparticles in a liquid crystal, wherein said ferroelectric nanoparticles function to change at least one of the following properties of the suspension when compared to the pure liquid crystal:

a) the dielectric anisotropy;

b) the phase transition temperature;

c) the birefringence; and

d) the order parameter.
