Organic LED light source for home electronics

Organic LED light source for home electronics

Electronic products pollute our environment with many heavy metals before, during and after they're used. In the U.S. alone, an estimated 70% of heavy metals in landfill come from discarded electronics. With flat screen TVs getting bigger and cheaper every year, environmental costs continue to mount.

To counter this, a new Tel Aviv University solution applies a discovery in nano-technology, based on self-assembled peptide nanotubes, to "green" the optics and electronics industry. Scientists Nadav Amdursky and Prof. Gil Rosenman of Tel Aviv University's Department of Electrical Engineering say their technology could make flat screen TV production green and can even make medical equipment - like subcutaneous ultrasound devices - more sensitive.

Inspired by a biomaterial involved in Alzheimer's disease research discovered by Prof. Ehud Gazit of the university's Department of Microbiology and Biotechnology, the researchers developed a new nano-material, applying the scientific disciplines of both biology and physics. This biological material is the basis for their new, environmentally-friendly variety of light-emitting diodes (LED) used in both consumer and medical electronics.

TV in a test tube?

Their new invention is more than a clean, green way to create light, the scientists say. It also generates a strong signal that can be used in other applications in the nano-world of motors, actuators and ultrasound.........
