摘要： 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.

摘要： A method is disclosed for controlling a pretilt angle direction for a liquid crystal cell comprising the steps of first setting the magnitude of pretilt angle and a plurality of pretilt angle directions in an alignment layer. This first step is achieved by irradiating linearly the alignment layer with polarized or unpolarized UV light. One of the plurality of pretilt angle directions is then selected by exposing the alignment layer to UV light a second time.
