Cheaper, 'Greener' Lighting with Inkjet

To make OLEDs more cheaply and easily, researchers from the University of Louisville in Kentucky are developing new materials and production methods using modified quantum dots and inkjet printing.The team will discuss its work developing more commercially feasible QD-OLED devices at the Conference on Lasers and Electro-Optics (CLEO: 2013)  in San Jose, Calif.




It's not easy going green. For home lighting applications, organic light emitting diodes (OLEDs) hold the promise of being both environmentally friendly and versatile. Though not as efficient as regular light-emitting diodes (LEDs), they offer a wider range of material choices and are more energy efficient than traditional lights. OLEDs can also be applied to flexible surfaces, which may lead to lights or television displays that can be rolled up and stowed in a pocket.
