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

POLYMER LIGHT EMITTING DIODES (PLEDs)

Ø 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.

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

Ø Polymers are largely identified with insulation.

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

ABSTRACT
Organic light emitting diode (OLED) display technology has been grabbing headlines in recent years. Now one form of OLED displays, LIGHT EMITTING POLYMER (LEP) technology is rapidly emerging as a serious candidate for next generation flat panel displays. LEP technology promises thin, light weight emissive displays with low drive voltage, low power consumption, high contrast, wide viewing angle, and fast switching times.
One of the main attractions of thi ....etc

Flexible Organic LEDâ„¢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 i ....etc
