LCD

abbreviation for liquid crystal display, a video display device that is more compact and uses less electrical power than the conventional cathode ray tube (CRT). Laptop computers use LCD displays. LCD monitors are frequently used instead of CRTs for desktop computers. An LCD is composed of electrically sensitive liquid crystals laminated between layers of plastic. Application of small electrical currents alters the orientation of the crystals, producing the image.

corneal dystrophy, lattice type 1

An autosomal dominant (OMIM:122200) form of corneal dystrophy characterised by wispy, greyish, cotton-like threads limited to a zone between the centre of the cornea and the periphery, with slowly progressive loss of vision by the fifth or sixth decade of life.

Molecular pathology
Has been linked to defects of TGFBI, which encodes an RGD protein that binds to type I, II and IV collagens and plays a role in cell–collagen interactions.

The dielectric anisotropy is higher in the nematic phase as compared to the temperature near N-I transition indicating a decrease in orientational order near transition temperature.
The mineral oil based emulsion with and without twisted nematic liquid crystal (cholesteryl stearate or stearin acid cholesteryl ester) additive was approved as an object of the investigation.
Use of either sulphuric or phosphoric acid yields a chiral nematic phase, but hydrochloric acid hydrolysis gives a viscous suspension that forms a birefringent, glassy phase after a "post-sulphation" treatment (Araki et al.
Nonetheless, for the widely used nematic liquid crystals that his group has investigated, "nothing like this has ever been done before," Patel asserts.
The highly ordered but non-crystalline chiral nematic state has only recently gained attention.
Types of PMLCD include twisted nematic (TN) LCD, super twisted nematic (STN) LCD, and color STN LCD.
The liquid crystalline mesophase exhibits a fine grained texture upon heating and fine nematic droplets, which coalesce firstly in small batonnets and then organize in more ordered mesophases displaying a fan-shaped texture, typical for smectic A phase (Figs.
Bulgaria) offer the first book devoted to the theory and practical application of partially oriented colloidal systems in nematic liquid crystals for infrared spectroscopic and structural elucidation in an embedded chemical in the solid state.
The author also describes the solid-state IR-LD spectra of samples of the various compounds studied as suspensions in nematic liquid crystal.
In its report, Flat Panel Monitor Trends 1999, the San Jose, California-based company says that STN-LCD super twisted nematic technology has now been all but squeezed out of the monitor market by thin firm transistor displays, and that the industry is moving towards a hybrid digital/analog interface that will speed up the transition from analog to digital.
The original VA technology was the first to introduce the use of liquid crystals with negative dielectric anisotropy and was able to achieve the faster response time and higher contrast of twisted nematic LCDs.
Out of the many different kinds of liquid crystals available, Yurke chose the nematic type, which consists of large, rod-shaped organic molecules.
