Report compares environmental impacts of LED, CFL and incandescent lights RICHLAND, Wash. – Today’s light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps. And that gap is expected to grow significantly as technology and manufacturing methods improve in the next five years, according to a new report from the Department of […]

LG Display’s tablet panel sales revenue more than doubles in Q2
LG Display more than doubled its tablet display sales revenue in the second quarter compared to the first, thanks to panel shipments for Apple Inc.’s iPad, according to the IHS iSuppli Small and Medium Display Service from information and analytics provider IHS. During its most recent results announcement with industry analysts, LGD said its tablet panel […]
Clemson researchers make optical fibers from common materials
CLEMSON — Clemson researchers are taking common materials to uncommon places by transforming easily obtainable and affordable materials into fiber. Their findings are published in Nature Photonics, the world’s top journal focused on light-based technologies. “We have used a highly purified version of beach sand (silica) for fiber for the last 40 years,” said John […]
LED light tower provides high-power and full portability
The WAL-18LED-BP portable and rechargeable LED light tower from Magnalight.com provides the high output of LEDs and the portability of rechargeable battery powered operation in a compact and easily deployed system. Designed for reliability and portability, this LED tower light can provide 14 hours of illumination in any location on a single charge and is […]
Chemists advance clear conductive thin films
PROVIDENCE, R.I. [Brown University] — In a touch-screen display or a solar panel, any conductive overlay had better be clear. Engineers employ transparent thin films of indium tin oxide (ITO) for the job, but a high-tech material’s properties are only half its resume. They must also be as cheap and easy to manufacture as possible. […]
Sharp to start shipping iPhone screens to Apple this month
(Reuters) – Japan’s Sharp Corp. said it will start shipping screens destined for a new Apple iPhone that is widely expected to be released in October ahead of the pre-Christmas shopping season. “Shipments will start in August,” Sharp’s new president, Takashi Okuda, said at a press briefing in Tokyo on Thursday after the company released […]
Researchers almost double light efficiency in LC projectors
Researchers from North Carolina State University and ImagineOptix Corporation have developed new technology to convert unpolarized light into polarized light, which makes projectors that use liquid crystal (LC) technology almost twice as energy efficient. The new technology has resulted in smaller, lower cost and more efficient projectors, meaning longer battery life and significantly lower levels […]
University of Utah physicists invent ‘spintronic’ LED
SALT LAKE CITY, July 12, 2012 – 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 in television and computer displays, lighting, traffic lights and numerous electronic devices. “It’s a completely different technology,” says […]
Carnegie Mellon’s smart headlight system will have drivers seeing through the rain
PITTSBURGH—Drivers can struggle to see when driving at night in a rainstorm or snowstorm, but a smart headlight system invented by researchers at Carnegie Mellon University’s Robotics Institute can improve visibility by constantly redirecting light to shine between particles of precipitation. The system, demonstrated in laboratory tests, prevents the distracting and sometimes dangerous glare that […]
What happened to transflective displays?
The most notable feature of this year’s SID Display Week was what wasn’t there: transflective displays. Sure, they were somewhere, tucked away in a corner or hidden in plain sight. But no one was talking about them anymore. Their conspicuous absence was underscored by their ubiquitous presence at the last two Display Weeks. So why […]
