Abstract.
We examine the utility of Light-Emitting Diodes (LEDs) for short-range intersatellite links (ISLs), and compare and contrast LEDs with existing laser technologies used for long-distance ISLs. A hypothetical low-end LED ISL page link is described, and applications are suggested

1. INTRODUCTION
Imagine having a high-definition TV that is 80 inches wide and less than a quarter-inch thick, consumes less power than most TVs on the market today and can be rolled up when you're not using it. What if you could have a heads up display in your car? How about a display monitor built into your clothing? These devices may be possible in the near future with the help of a technology called organic light-emitting diodes (OLEDs). OLED is a flat display technology, made by placing a series of organic t ....etc

Definition
Scientific research in the area of semiconducting organic materials as the active substance in light emitting diodes (LEDs) has increased immensely during the last four decades. Organic semiconductors was first reported in the 60:s and then the materials where only considered to be merely a scientific curiosity. (They are named organic because they consist primarily of carbon, hydrogen and oxygen.). However when it was recognized in the eighties that many of them are photoconductive under visible light, industrial interests were att ....etc

Flexible Organic LED s


Presented By: Ryan Evans



What the Flexible Organic Light Emitting Diode Consist of :

The Top Layer is the Cathode layer made of tungsten releases electrons when current is run through it.

Emissive Layer removes electrons from the cathode layer to make light.

Conductive layer is made from a type of organic plastic that removes the electron wholes

Then the Anode Layer that consist of removing and adding electron holes while the current is running through it and i ....etc

POLYMER LIGHT EMITTING DIODES (PLEDs)

Polymer LED (light-emitting diode) - sometimes called light-emitting polymer or polyLED - is a technology based on the use of polymer as the semiconductor material in LEDs.

Polymers are chemical substances that consist of large molecules that are themselves, made from many smaller and simpler molecules.

Polymers are largely identified with insulation.

Research institutes have come up with ideas to integrate polymers into main stream electronics as it has been established that certain poly ....etc

The seminar is about polymers that can emit light when a voltage is applied to it. The structure comprises of a thin film of semiconducting polymer sandwiched between two electrodes (cathode and anode).When electrons and holes are injected from the electrodes, the recombination of these charge carriers takes place, which leads to emission of light .The band gap, ie. The energy difference between valence band and conduction band determines the wavelength (colour) of the emitted light.
They are usually made by ink jet printing process. In this m ....etc

I am looking for olet ppt.Organic materials are of great interest for electronics applications, as they have many advantages over their inorganic counterparts.They may often be solution-processed, allowing the fabrication of devices such as circuits,displays,and radio-frequency identification deviceson plastic substrates, and deposition by unconventional means, such as screen and inkjet printing.The most attractive prospect, however, is the incorporation of functionality by design. The versatility of organic synthetic techniques and the wide sp ....etc
