Latest Patents
One of his notable patents is for "Polymer enhanced cholesteric electro-optical devices." This invention provides liquid crystal devices that consist of a composite of an internal polymer network localized on substrate surfaces and short-pitch dual-frequency switchable cholesteric liquid crystal. These devices operate in two different modes, including in-plane switching (amplitude modulation) and out-of-plane switching (phase modulation). The invention also outlines a method for creating a liquid crystal device that demonstrates a uniform lying helical axis, which can be utilized in flat panel displays and spatial light modulators for various applications such as optical waveguides and adaptive optics.
Another significant patent is the "Method of fabricating electro-optical devices with polymer-stabilized liquid crystal molecules." This preparation method involves a chiral or cholesteric liquid crystal, a photoreactive monomer, and a photoinitiator within a liquid crystal cell. The method includes illuminating a principal surface of the cell with ultraviolet light, which polymerizes the photoreactive monomer to generate a polymer network that biases the liquid crystal toward a selected helical alignment direction.
