Liquid Crystal Technology

Colloids hold a considerable potential for applications that are unusual in the classical sense. Most of us are familiar with imaging devices such as the picture tube in a television set. These tubes are bulky and consume large amounts of electrical power. There is, therefore, a large incentive to develop compact imaging devices, known as flat-panel devices, that are easily portable and have lower power requirements. (Displays based on liquid crystal technology fall in this class.)...

Over a century ago, Professor Otto Lehmann of the University of Karlsruhe - who is acknowledged as the pioneer of liquid crystal technology - disagreed with the scientific establishment about the existence of the liquid crystalline state of aggregation. Lehmann turned to Merck. He asked the company to supply him (and others) with liquid crystalline compounds so that he could clarify what no amount of theoretical debate could resolve. This was Merck s first foray into the LC business - although there was no actual business at this stage. Nevertheless, it was already well known that Merck supplied products of the highest purity, which allowed results to be replicated accurately. 

In a related process, or //o-dialkoxybenzenes undergo an unusual anodic trimeriza-tion reaction, leading to hexaalkoxytriphenylenes (LXIV) [Eq. (30)], certain of which have found application in the field of liquid crystal technology [72,73].

Other forms ofvery fine oxide fibers exist or are being developed. Single crystal whiskers which pose health risks and also present difficulties for handling, because of their very small dimensions, have not found wide use. Nano-oxide fibers are being developed which may be fine enough for liquid crystal technology to be used so as to handle them but as yet remain a possibility for the future.

New electro-optic technologies continue to be developed, and some of them make inroads into the LCD market. Nevertheless, liquid crystal technology - the first other than the CRT to make a significant breakthrough into the mass market and which made possible flat displays and transformed projection display technology - continues to hold a dominant position. This second edition of Fundamentals of Liquid Crystal Devices, with its additions which include references to some very recent work, will ensure that this volume will continue to provide students and other readers at the professional level with a most useful introduction to the subject.
