Scanning Electron Microscopy

Abstract

Displays provide the essential human interface to virtually all electronics instrumentation. The market is large with new applications appearing every year; sometimes with profound impact. Digital watches with liquid crystal displays appeared in the early 1970s and have virtually wiped out the mechanical timepiece industry. Personal computers with cathode ray tube (CRT) displays are proliferating with diverse applications in the industry and in the home. Work stations with high-resolution color displays are changing the way architects, draftsmen, and IC designers perform their job. The CRT is the dominant technology in today's market, and will, no doubt, continue to be for some years to come. High-resolution shadow-mask tubes will capture a larger and larger market share in the coming years. Projection displays will grow rapidly with the introduction of systems based on new technologies and with the advent of high definition TV. The flat panel industry is growing at 30 percent per year, not so much from taking business away from CRTs, as in the creation of new applications. This is an area rich in technologies with many contenders such as plasma, electro-luminescence, liquid crystal, vacuum fluorescent, electro-chromic, and others.
