ABSTRACT
With a 100-year head start over more modern screen technologies, the CRT is still a formidable technology. It s based on universally understood principles and employs commonly available materials. The result is cheap-to-make monitors capable of excellent performance, producing stable images in true colour at high display resolutions. But in the world of miniaturization, Cathode ray tubes (CRT) are giant dinosaurs waiting for extinction. A CRT uses a single-point hot electron source that is scanned across the screen ....etc

ABSTRACT


A surface-conduction electron-emitter display (SED) is a flat panel color television technology currently being developed by a number of companies. Surface-conduction Electron-emitter Displays are a new, emerging technology co-developed by Canon and Toshiba Corporation. The hope for this technology is a display which reproduces vivid color, deep blacks, fast response times and almost limitless contrast. In fact, if you take all of the claims made by the backers of SED you wou ....etc

A LOW COST FIELD USABLE PORTABLE DIGITAL GRAIN MOISTURE
METER WITH DIRECT DISPLAY OF MOISTURE (%)

ABSTRACT:-
Moisture content of grain is one of the important parameters always considered
when deciding the quality and price of grain, at the stage of harvesting, storage, processing and
marketing. Grain having excess moisture content, if stored for long duration, will spoil due to
insect/fungus infestation. Portable, field usable, and easy-to-use direct moisture (%) display Grain
Moisture Meter is a necessi ....etc

INTRODUCTION
Various types of displays have become common in the every day life. The displays are used in televisions, computers etc. They also have wide use in laboratories and in medical applications. The displays are those devices by which we can view moving objects. The displays are manufactured depending upon their application.

One of the hottest markets driving physics research is the demand for a perfect visual display. People want, for example, large, thin, lightweight screens for high-definition TV and outside displays and very hi ....etc

Field emission microscopy (FEM)
abstract

Microscopy techniques are used to produce real space magnified images of a surface showing what it looks like. In general microscopy information concerns surface crystallography (i.e. how the atoms are arranged at the surface, surface morphology (i.e. the shape and size of topographic features making the surface), and surface composition (the elements and compounds the surface is composed of).
Field emission microscopy (FEM) was invented by Erwin M ller in 1936. In FEM, ....etc
