[The electroluminescence of organic and polymer thin film materials]

In recent years, researches on electroluminescence (EL) of organic and polymer thin film materials have been made with an outstanding progress, and have attracted much interest because of its large-area, full color, high luminance displays which can be driven with low dc voltage. In this paper, the history of the development on electroluminescence, the devices and the selection of luminescent materials and the electroluminescence principle are introduced briefly.
