Wide Viewing Angle Liquid Crystal Displays
… applied to the designs of wide viewing angle and high transmittance liquid crystal displays. First, a design of wide viewing angle liquid crystal displays utilizing crossed linear polarizers is proposed. The designed multi-domain vertical-alignment liquid crystal display predicts superb contrast …

Microstructuring and domain-engineering of lithium niobate using combinations of light, etching and poling
… The total internal reflection switch shows high contrast ratio switching of greater than 20dB and is less wavelength dependent than other electro-optic switches, such as the Pockels cell. The beam deflector can produce large angular deflections, which are increased by faceting of the output …

Photoluminescent quantum-dot light emitting devices controlled by electric field induced quenching
… potential applications for a new generation of display and lighting technologies. The emission control of QDs in a QD light-emitting device (LED) is usually achieved by changing the injection current density. However, these devices face issues with lifetime and stability as well as low …

High Birefringence And Low Viscosity Liquid Crystals
… anisotropic LCs, we have developed some high birefringence isothiocyanato tolane LC compounds with birefringence ~0.4, and super high birefringence isothiocyanato biphenyl-bistolane LC compounds with birefringence as high as ~0.7. Moreover, we have studied the photostability of several …
