INTRODUCTION

Light emitting polymers or polymer based light emitting diodes discovered by Friend et al in 1990 has been found superior than other displays like, liquid crystal displays (LCDs) vacuum fluorescence displays and electro luminescence displays. Though not commercialised yet, these have proved to be a mile stone in the filed of flat panel displays. Research in LEP is underway in Cambridge Display Technology Ltd (CDT), the UK.

Light-emitting polymers




ABSTRACT
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 ....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

Light Emitting Polymers

-A light emitting polymer is an electro-luminescent plastic. The molecules of this plastic emit light when an electric field is applied.

-Polymer based light-emitting diodes (LED) were discovered in 1990.

-Cambridge Display Technology has the core patents for the Technology of LEP.

ABSTRACT
PHOLED (phosphorescent organic light-emitting device) is a proprietary display technology developed by the Universal Display Corporation (UDC) that uses soluble phosphorescent small molecule materials to create organic light-emitting devices (OLEDs). PHOLED technology works on the principle that certain organic molecules emit light when an electric current is applied.
Although PHOLED was originally developed as a display technology for use in mobile phones, the U.S. Department of Energy . PHOLED-based lighti ....etc
