Paper Abstract

This review summarizes the recent progress in the development of light emitting diodes (LEDs) and their application that have been reported. New types LED's will become possible by the use of inorganic and recently new organic semiconductors. The main goal in inorganic nitride based device technologies is to increase the performance above 100 lm/W and to use blue high brightness (HB) LEDs as a basic light source in high brightness white light devices. Organic LEDs are an interesting, prospective choice as a source of light for applications. Recent improvements have taken OLEDs to luminous efficiency greater than 20 lm/W, lifetime in excess of 10,000 hours and driving voltage of 5V and below. As LEDs continue to advance in brightness and efficiency, their effect on general lighting, automotive headlamps and television application could be significant to produce a huge impact on our future daily life.
