New bistable twisted nematic liquid crystal displays
We have developed new bistable twisted nematic ~BTN! displays that operate between the 2p/2 and 3p/2 twist states and between the p/2 and 5p/2 twist states. Together with the ~0,2p! BTN, this forms a set of all possible transmittive BTNs. Experimentally, it was confirmed that several switching wave forms could be used to switch the BTN from one state to another. Voltages below 10 V are sufficie...
متن کاملExperimental and Theoretical Study of Electroconvection in Homeotropic Nematic Liquid Crystal
Electroconvection patterns have been studied in a homeotropic nematic liquid crystal, experimental and theoretical, with unusual combination of material parameters, negative conductivity and positive dielectric permittivity anisotropies. Exploring the complete phase diagram in the (U, q) space three distinct morphologies, rolls and squares, soft squares and hard squares have been identified. We...
متن کاملEffect of material properties on reverse flow in nematic liquid crystal devices with homeotropic alignment
Reverse flow is undesirable in liquid crystal devices with vertical alignment. The influence of the material properties on the onset of backflow is investigated for commercially available negative dielectric liquid crystals. It is shown that the threshold voltage VBF for the occurrence of backflow is an important material characteristic. This threshold is relevant for applications and a large v...
متن کاملOptimization of reflective bistable twisted nematic liquid crystal displays
The contrast ratio of reflective bistable twisted nematic displays are optimized by means of a parameter space approach. By plotting the contrast ratio as a function of the twist angle and thickness-birefringence product of the display, the regions where the display shows the best contrast ratio are clearly shown. Both the absolute reflectance and wavelength dispersion of two bistable twisted s...
متن کاملThree-terminal bistable twisted nematic liquid crystal displays
A three-terminal bistable twisted nematic liquid crystal display has been demonstrated. This display makes use of a combination of strong in-plane electric fields and vertical electric field for switching between the f and the f1p twist states. The lifetimes of the two bistable twist states are infinite, which is a significant improvement over conventional bistable twisted nematic displays. © 2...
