ne·mat·ic

 (nə-măt′ĭk)
adj.
Of or relating to the mesomorphic phase of a liquid crystal in which the molecules are oriented in loose parallel lines.

[From Greek nēma, nēmat-, thread; see (s)nē- in Indo-European roots.]

nematic

(nɪˈmætɪk)
adj
(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
[C20: nemat(o)- (referring to the threadlike chains of molecules in liquid) + -ic]

ne•mat•ic

(nɪˈmæt ɪk)

adj.
(of liquid crystals) noting a mesomorphic state in which the arrangement of the molecules is linear. Compare smectic.
[1920–25; < Greek nēmat-, s. of nêma thread + -ic]

The traditional liquid crystal display (LCD) is a sandwich construction, starting from a bottom layer for the backlight and its associated optics, then a pair of glass layers on either side of a layer of nematic liquid crystals, a polarizing layer, a color filter, and perhaps an independent environmentally protective layer.
Davis Mok, vice president of Marketing in MagnaChip's Display Solutions Division, commented, "Our most recent a-Si TFT panel drivers are not only the most universal Twisted Nematic (TN) types, but also provide one of the best image qualities among high-end a-Si TFT panels supporting a wide viewing angle.
Key features include the use of FSTN (film supertwist nematic) LCD technology for visibility in direct sunlight; backlighting; a Deutsch connector interface to the CANbus; protection to IP67; and an operating temperature range of-40[degrees] to 75[degrees]F.
When aqueous suspensions of cellulose nanocrystals are allowed to dry, the chiral nematic orientational order present in the suspension remains in the solid (Revol et al., 1997, 1998).
Specific subjects in this area might include: Nematic ordered cellulose and varying levels of structure in the cellulosic phase, and the effect of structural modification on the physical chemistry of the cell wall during biosynthesis."

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.
Solomon Systech's display IC technologies include families of monochrome, gray scale and color Super Twisted Nematic (STN), Thin-Flim-Transistor (TFT) and OLED controller driver integrated circuits.
It said it was the first company to commercialize single-chip display drivers for full-color organic light-emitting diodes, or OLEDs, and its product portfolio includes color super-twisted nematic liquid crystal display and passive matrix OLED display drivers.
The company will operate in LCD module industry with an annual capacity to produce 4.8 million units of twisted nematic LCD module, 2.7 million units of super twisted nematic LCD module and 1.8 million units of thin film transistor.
We then poured them densely into the tray obtaining the nematic non-lattice structure like the spin glass (Fig.
