Nematic

Some articles on nematic, nematics:

LCD Classification - Bistable LCDs
... For some applications bistability of electro-optical effects is highly advantageous, since the optical response (visual information) is maintained even after removal of the electrical activation, thus saving battery charge ... These effects are beneficial when the displayed visual information is changed only in extended intervals (e.g ...
Liquid Crystal Display - Active Matrix Technologies - Twisted Nematic (TN)
... See also twisted nematic field effect Twisted nematic displays contain liquid crystals that twist and untwist at varying degrees to allow light to pass through ...
Liquid Crystal Phases - Thermotropic Liquid Crystals - Nematic Phase
... See also Biaxial nematic and Twisted nematic field effect One of the most common LC phases is the nematic ... The word nematic comes from the Greek νήμα (nema), which means "thread" ... This term originates from the thread-like topological defects observed in nematics, which are formally called 'disclinations' ...
Biaxial Nematic
... A biaxial nematic is a spatially homogeneous liquid crystal with three distinct optical axes ... This is to be contrasted to a simple nematic, which has a single preferred axis, around which the system is rotationally symmetric ... The symmetry group of a biaxial nematic is i.e ...
