Quantum dot LED approaches theoretical maximum efficiency
New LED packaging technology improves performance
Inkjet-printed graphene electrodes may lead to low-cost, large-area, possibly foldable devices
Nano-LEDs emit full visible spectrum of light
White LEDs with super-high luminous efficacy could satisfy all general lighting needs
Scientists build thinnest-possible LEDs to be stronger, more energy efficient
(Phys.org) —Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors ...
Wagon-wheel pasta shape for better LED: 'Rotelle' molecules depolarize light more efficiently than 'spaghetti'
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or ...
LG Chem cable batteries may reshape mobile designs
New material could speed up underwater communications by orders of magnitude
(Phys.org) —University of California, San Diego electrical engineering professor Zhaowei Liu and colleagues have taken the first steps in a project to develop fast-blinking LED systems for underwater optical ...
Toward a truly white organic LED: Physicists develop polymer with tunable colors
By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to "tune" the plastic-like polymer to emit light of different colors – a step toward more efficient, less ...
Soraa LED light may dim 50-watt halogen rivals
Cause of LED efficiency droop finally revealed: Auger recombination responsible
(Phys.org)—Researchers at University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have conclusively identified Auger recombination as the mechanism ...
TED SpaceTop presenter is redefining hands-on computing (w/ video)
PEDOT:PSS: Improving thermoelectric materials that convert heat to electricity and vice-versa
Thermoelectric materials can be used to turn waste heat into electricity or to provide refrigeration without any liquid coolants, and a research team from the University of Michigan has found a way to nearly double the efficiency ...
