University of Utah physicists invented a new "spintronic" organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used ...
Light-emitting diodes -- LEDs -- can do way more than illuminate your living room. These light sources are useful microelectronics too. Smartphones, for example, can use an LED proximity sensor to ...
Computers the size of dust particles could be fabricated thanks to newly developed light sources, which achieve high efficiency at low power. Networks of minuscule computers, although potentially ...
