Introduction

A type of display screen that has a touch-sensitive transparent panel covering the screen. Instead of using a pointing device such as a mouse or light pen, you can use your finger to point directly to objects on the screen.
Although touch screens provide a natural interface for computer novices, they are unsatisfactory for most applications because the finger is such a relatively large object. It is impossible to point accurately to small areas of the screen. In addition, most users find touch screens tiring to the arms after ....etc

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 to produce an image.

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 Müller in 1936. In FEM, ....etc

FIELD EMISSION DISPLAY
What is Field emission?
Definition:
The emission of electrons stripped from parent atoms by a high electric field via quantum mechanical tunneling.
It is also called as Fowler-Nordheim tunneling because they explained the basic principles in 1928.
FED Principles
In Field emission display, electrons coming from millions of tiny micro-tips pass through gates and light up pixels on a screen.
This principle is similar to that of cathode-ray ....etc
