Latest Patents

One of Harper's key patents is for a guest-host liquid crystalline composition. This innovative nematic liquid crystalline composition includes a unique chiral compound, (+)5-(2-methyl) butyl-2(4-cyanophenyl)-1, 3-dioxane. When combined, these components create a phase-change cholesteric liquid crystalline composition that serves as an effective host medium in guest-host electrooptical displays. This composition is characterized by its low electrical threshold and optical saturation voltages, steep saturation curve, relatively low optical birefringence, low viscosity, and broad liquid crystalline mesomorphic range. The improved guest-host composition, when used with a suitable pleochroic dye, exhibits a contrast of greater than 3:1 in specific displays, particularly those with a moderate tilt angle of 10°-40° at the substrate/guest-host composition interface.
