(Chemistry) chem (of a substance) existing in or having a mesomorphic state in which a linear orientation of the molecules causes anisotropic properties. Compare smectic See also liquid crystal

There are a number of types of LCD technology such as Super Twisted Nematics (STN), Dual Scan Twisted Nematics (DSTN), Ferroelectric Liquid Crystal (FLC) and Surface Stabilized Ferroelectric Liquid Crystal.
Despite this limitation, the model incorporates all features believed to be essential to LCPs: director tumbling in shear, interdomain interactions mediated by distortional elasticity, and texture refinement (the generation of new defects under shear in tumbling nematics).
Liquid crystals can be nematic; i.e., having molecules oriented along one axis, but disordered along the perpendicular axis; smectic, which have the same orientation order of nematics, but align themselves in layers or planes, and cholesteric (Lipocrystals) which produce molecular forces that align the molecules at slight angles to one another.
Displaytech faces competition from start-ups such as San Pablo, California-based MicroDisplay Corp, which says its twisted nematics LCDs offer in- between states for greyscale displays, and therefore avoid the power-consuming on-off switching mode used by Displaytech.

The orientational response of nematics to shear flow is profoundly affected by [lambda].
Currently LCD has various technologies such as Super Twisted Nematics (STN), Dual Scan Twisted Nematics (DSTN), Ferroelectric Liquid Crystal (FLC) and Surface Stabilized Ferroelectric Liquid Crystal
It is now possible to link this model to the theory of nematics in a constant external field.
The most common configuration of the PDLC droplets is the so-called bipolar configuration arising from the well known tendency of many nematics to anchor tangentially to polymer surfaces [ILLUSTRATION FOR FIGURE 1 OMITTED].
