Flexible LEC Components for Efficient Light Emission

Researchers from Umeå University and Uppsala University have developed a new method to con-trol the light emission of light-emitting electrochemical cells, in short LEC. The study is published in Advanced Materials. The LEC light source is extremely thin, flexible and light and can now be easily modified to be up to 60% more efficient through simple and inexpensive changes to the materials in the active layer. “We show that you can control the position where light is formed in the ac...
