New LED technology 'can be applied like paint'

28 August 2015

A Florida State University academic has developed an efficient, low cost light emitting diode technology that is far simpler to manufacture than existing products.

"It can potentially revolutionise lighting technology," claims Assistant Professor of Industrial and Manufacturing Engineering Zhibin Yu. "In general, the cost of LED lighting has been a big concern thus far. Energy savings have not balanced out high costs. This could change that."

Yu developed his new LED technology using a combination of organic and inorganic materials. The material, which dissolves and can be applied like paint, shines a blue, green or red light and can be used to make a light bulb. But what makes it really special is that it's far simpler to manufacture than existing products on the market.

Most LED materials require four or five layers of material placed on top of each other to create the desired product or effect. Yu's material only requires one layer.

His research has resulted in an award by the US National Science Foundation to further investigate the essential materials and establish the processing platform for the development of intrinsically stretchable, active-matrix organic LED displays.

The work is reported in the journal, Advanced Materials.
