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

ABSTRACT
In the present world, the display technology is usually analog. But, we present the future technology i.e., the digital technology. The analog display technologies limit the full potential of digital video. So, the digital display devices will be in the market soon. In our paper, we emphasize on Digital Light Processing (DLP). This DLP display technology manipulates the light digitally to produce all-digital images. This technology reproduces color images with precision accuracy in a seamless fashion. The picture ap ....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

Powered by digital electronics, this optical solution facilitates the entire digital connection between a graphic or video source and the screen, in movie video projectors, televisions, home theatre systems and business video projectors. Digital Micro mirror Device or DLP® chip which is a rectangular array of up to 2 million hinge- mounted microscopic mirrors (each of these micro mirrors measures less than one-fifth the width of a human hair) controls the light in optical semiconductor of the DLP projection system.

ABSTRACT
In the Modem era where technology is at high state, need for new machineries and instruments are a prerequisite. Demand for high efficient measuring system and interactive displays make user-friendly capabilities. In the entertainment section high precision imaging is needed for efficient operation.
With advent of OLEDs, conventional LEDs and LCDs are becoming history. High imaging techniques of OLEDs make the critical fields such as defense and research more efficient in operation.
With this ....etc

ABSTRACT
A head-up display system projects an image directly onto the human retina with low-energy lasers or LCDs. Head-up displays can give the user ' the illusion of viewing a typical screen-sized display hovering in the air several feet away. In principle the technology can provide full-color, high¬resolution dynamic displays, but in practice the components necessary to achieve the full potential of the technology are either highly expensive. ; Although the technology was invented by the University of Washingt ....etc
