The LED paint
LED lighting is already sold in stores, but widespread adoption has been slow because of the costs associated with the material and the quality. Energy savings are not balancing out high costs. This could change with a new LED technology, which is using a combination of organic and inorganic materials. It 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. The new material only requires one layer. In the future, to do manufacturing, it's a big challenge if you have to deal with multiple layers.
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.
