Single material layer process lowers LED manufacturing costs

"It can potentially revolutionize lighting technology," said 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 the LED technology using a combination of organic and inorganic materials. The material, which dissolve 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 engineers to put four or five layers of material on top of each other to create the desired product or effect. Yu’s material only requires one layer.

"In the future, to do manufacturing, it’s a big challenge if you have to deal with multiple layers," said Yu.

The research has resulted in an award by the 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 discovery was reported in the journal Advanced Materials.

According to the U.S. Department of Energy, residential LED lighting uses at least 75 percent less energy than regular incandescent lighting.
