Abstract

An electroluminescence generating device comprising e. a channel of organic semiconductor material, said channel being able to carry both types of charge carriers, said charge carriers being electrons and holes; f. an electron electrode, said electron electrode being in contact with said channel and positioned on top of a first side of said channel layer or within said channel layer, said electron electrode being able to inject electrons in said channel layer; g. a hole electrode, said hole electrode being spaced apart from said electron electrode, said hole electrode being in contact with said channel and positioned on top of said first side of said channel layer or within said channel layer, said hole electrode being able to inject holes into said channel; h. a control electrode positioned on said first side or on a second side of said channel; whereby light emission of said electroluminescence generating device can be acquired by applying an electrical potential difference between said electron electrode and said hole electrode.
