Permanent gray-scales in bistable twisted nematic liquid-crystal displays: Permanent gray-scales in bistable twisted nematic liquid-crystal displays. Xie, Z. L.; Meng, Z. G.; Wong, M.; Kwok, H. S. (Center for Display Research, Hong Kong University of Science and Technology, Hong Kong, Peop. Rep. China). Applied Physics Letters, 81(14), 2553-2555 (English) 2002 American Institute of Physics. CODEN: APPLAB. ISSN: 0003-6951. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Permanent gray-scales in a p bistable twisted nematic-liq.-crystal display have been demonstrated. This display can be switched between the -22.5° and 157.5° twist states by a combination of a strong in-plane elec. field and a vertical elec. field for creating both planar anchoring breaking and an electrohydrodynamic back-flow. The switching of the twist states during the Frederiks transition is sufficiently inhomogeneous such that domains of -22.5° and 157.5° twisted states can coexist permanently. The ratio of these domains can be controlled by the vertical elec. 87321-20-8 and 488114-45-0 are just another two chemicals used in this study. field. .
