This disclosure outlines a new method of modifying the properties of existing liquid crystals by doping them with ferroelectric micro- and nanoparticles. We show that this approach, in contrast to the traditional time consuming and expensive chemical synthetic methods, enriches and enhances the electro-optical performance of many liquid crystal materials. We demonstrate that by changing the concentration and type of ferroelectric particles the physical properties of the nematic, smectic, and cholesteric liquid crystal materials can be changed, including the dielectric constants, the birefringence, the phase transition temperatures, and even the order parameter. We also demonstrate the performance of these new materials in various devices, including displays, light modulators, and beam steering devices.

Non-synthetic method for modifying properties of liquid crystals

A method is provided for forming an alignment layer for a liquid crystal cell that is made from a liquid crystal film that has been irradiated with light. The method includes the steps of disposing a liquid crystal film on a substrate and then irradiating the liquid crystal film with light. Also, a liquid crystal display that includes an alignment layer that is a liquid crystal film that has been irradiated with light.

Method for alignment of liquid crystals using irradiated liquid crystal films

An optical compensation film for a liquid crystal display is provided wherein the film is a polymer that is capable of producing light induced anisotropy. The film is irradiated with light to form an optical axis or axes.
