This finding can help to produce low-cost OLED displays in the coming years, instead of technicians using costly microfabrication facilities to construct small-scale structures such as computer chips, smartphone displays, etc. The detailed study is published in Science Advances . OLED Technology- Overview OLED stands for Organic Light-Emitting Diode- a technology that uses LEDs to produce light by organic molecules. This technology helps to create the world’s best display panels. Organic displays are prepared by placing thin films of organic semiconductors such as silicon or gallium arsenide between two conductors. These films emit a bright light when an electric current is applied. Each pixel emits its own light and is controlled indivi

Can we 3D print our organs?

Right from an actual firing gun to a camera lens , funky phone holders to even a musical flute, 3D printing has expanded our horizons of what can be made by with the help of a computer. But can we trust this technology to go beyond these everyday things and make something that can be truly life saving? Well, there have been reports where 3D printing has helped doctors create a replica model of a faulty heart before attempting surgery on a two year old   or even help trauma patients rebuild their faces with 3D printed parts , but we would like to push these frontiers even further and get these printers to print something more amazing, more like a liver we could transplant or a heart that could pump blood for real.  While this might sound like a technology stolen from the future, the fact is that there are companies working today towards making this possible and have even got as far as printing a particular tissue on demand.
