What is organic EL?

As well as supplying OLED materials with world-class performance to meet market needs, Idemitsu uses technologies developed over many years to offer total solutions including recommending optimum device structure.

When electric current is run through a certain organic compound, the molecules of the compound situated between positive and negative electrodes are excited by the electric energy and emit light due to the energy difference when they return to their original state.
OLED makes use of this light-emitting phenomenon, which is called electroluminescence.
