Cree Demonstrates High Quality 150-mm Silicon Carbide Substrates
LIGHTimes News Staff
September 3, 2010...Cree of Durham, North Carolina USA, has reported a silicon carbide advance that the company says will help lead to wide scale commercialization of SiC.
The company demonstrated high quality, 150-mm SiC substrates with micropipe densities of less than 10/cm2. The current Cree standard for SiC substrates is 100-mm diameter material.
SiC is a high-performance semiconductor material used in the production of a broad range of lighting, power and communication components, including LEDs, power switching devices and RF power transistors for wireless communications. The company contends that the significant size advancement of single crystal SiC substrates to 150-mm can enable cost reduction and increased throughput, while bolstering the continued growth of the SiC industry.
“Cree’s achievement of 150-mm SiC substrates further demonstrates Cree’s leadership in SiC materials technology,” said Dr. Vijay Balakrishna, Cree Materials product line manager. Steve Kelley, Cree chief operating officer, added, “We expect that 150-mm substrates can reduce device cost, boost manufacturing output and expand our product range."
AUO Raising LED backlight Proportion for Notebook and Monitor Panels
September 3, 2010...AU Optronics (AUO) is increasing its applications of LED backlights for its TFT-LCD panels used in notebooks and LCD monitors, according to Digitimes article. The company reportedly plans to increase the LED backlight proportion for its notebooks from 98% currently to 100% at the end of 2010. AU Optronic says it also plans to increase the proportion of LED backlit LCD monitors from 25 percent in the second quarter of 2010 to 100% in 2013. AUO points out that its LED-backlit TV panels range between 24- to 65-inch models, and the LED-backlit LCD monitors go up to as large as 27 inches. The company says it is developing LED backlit 3D panels for TV, monitor and notebook applications. AUO plans to introduce its 65-inch TV panels with built-in 3D display function in the fourth quarter of 2010, and AUO notes that LED backlit 3D notebook panels and 23- and 27-inch LED-backlit 3D monitor panels will come in 2011. For touch panel products, AUO indicated that it can provide 5- to 10-point multi-touch solutions, and all-in-one PCs and tablet PCs.
Tel Aviv University Researchers Developed OLED made with Self-Assembled Peptide Nanotubes
LIGHTimes News Staff
August 31, 2010...Researchers from Tel Aviv University’s Department of Electrical Engineering have developed self-assembled peptide nanotubes which they hope will “green” the optics and electronics industry, according to an article in ScienceBlog.com. Researchers Nadav Amdursky and Prof. Gil Rosenman of Tel Aviv University’s Department of Electrical Engineering say their technology could make flat screen TV production green and can even make medical equipment such as subcutaneous ultrasound devices more sensitive.
The technology is reportedly inspired by a biomaterial involved in Alzheimer’s disease research discovered by Prof. Ehud Gazit of the university’s Department of Microbiology and Biotechnology. The scientists from the Electrical Engineering Department developed a new nano-material, applying the scientific disciplines of both biology and physics. This biological material is the basis for their new, environmentally-friendly variety of OLEDs which might someday be used in consumer and medical electronics.

LED Lighting Summit Buzz: Walking the walk with decision makers
Tom Griffiths - Publisher
August 26, 2010...It's interesting when you arrange something like the LED lighting-focused SSL Summit to see who's really ready to walk the walk, rather than just talking the talk. Here you have an conference that's bringing in real facilities-oriented decision makers that should represent somewhere between 200 and 300 million square feet of commercially managed property in NYC, and that demands the "product visible" companies to meet some basic quality criteria. Suddenly more than a few of the hundreds of manufacturers that you see at the big lighting shows, and in the news, seem to have cold feet. Time to walk the walk.
That's not to say that if a company isn't there that you should assume there's an issue. There are plenty of great companies that are simply looking at where the bodies have to be, and when, and not able to fit it in all into the schedule. "Attend the board meeting or go to the Summit... hmmm. I'll just blow off my investors, they'll understand," says the CEO (not). There are also more than a few startups that simply have $XXX per month to travel on, and those sales calls are already scheduled. Hey, we all have budgets, and the discipline to live with them is one key to success. There are also the ones who haven't heard about it (consciously). We have more than one industry friend who are avid readers, must have the banners in their faces at least weekly, and that reply with, "Oh shoot... I didn't notice the dates. Is that coming up in just a few weeks?" The sign-up typically follows the next day or two, as soon as they have the flights.
There will also be plenty of attending manufacturers that are bringing quality to the market, but didn't choose to be in the sponsor's showcase or didn't get in early enough to have a talk. Lack of product on display is not a measure of whether they have a worthwhile product or not. Those are decisions to be made about promotion and exposure. We all have our opinions on where and how it's best to invest, and we'd all do things differently with an unlimited budget, but no one in their right mind would ever give marketing an unlimited budget. (Insert your favorite political diatribe on government spending programs here for illustration...)
The companies that we find interesting are those big talkers that stormed Lightfair with their "wide range of products" and "great performance", who are suddenly confronted with the possibility of facing actual high-level customers. "We're not quite ready to be there yet." Interesting. If they could get through to the decision makers at all, they'd be qualifying with just the right words such as, "Looks good for availability this fall," when it could be rightly restated as, "If everything went smoother than ever has happened, we can make one available to the labs for testing to see if it comes close to matching what we put on our preliminary spec sheet." I guess that means, "Would look good for availability...". What I suspect they're hoping is that the only thing that will stick is the company name so they can get through again "when they're ready" and start things rolling for real. Good luck with that. Again, don't assume this is condemnation of anyone with a schedule slip versus expectations. If you don't plan aggressively, you won't achieve aggressively, and quite frankly, the only way you know you've gotten to the edge is to slip a bit and catch your balance. Ask anyone in motorsports. You need to go to the edge to find out where the edge is. The talent is in learning to hang on that edge without blowing out of the corner. That's why many, many entrepreneurs have a failure in their past. It's how they learned to do it right (and faster) this time.
So who will you find there? Winners. Not the only winners, but a good representation of companies that are offering competent solutions. All have made mistakes, I am sure, with some of those mistakes being visible and others having escaped the light of day. That decision making audience will also be made up of winners, whether they are designers, consultants or engineers, or personally managing a few million square feet (let's see... 2M sqft x $50/sqft rent makes a tidy little $100M business they're running with an equivalent market cap of a quarter to a half billion). Winners will also be there in lower key ways, even if their product isn't yet to the point they want to shine the kind of spotlight on it that others might. They're winners because they're working to engage with other winners.
Special thanks to our 2010 Summit NY and Series supporters, including diamond sponsors Lithonia Lighting and LEDnovation. Platinum sponsors include Wiedenbach Brown, Greenlight Initiative, Toshiba, Graftech and Array Lighting. This year's showcase participants also so far include Gold sponsors CRS, Cree, and Philips Lumileds.
================
Don't miss the SSL Summit Series, kicking off September 14-15 in New York City, conveniently located on Manhattan in the financial district. It's all about quality, so if you are a luminaire manufacturer that would like to connect with some of the top lighting decision makers in the area, you won't find a more efficient two days during this year. Any luminaire manufacturer receiving product visibility is being vetted for basic quality criteria, but if your company doesn't quite have those LM-79 reports and datasheets all matched up yet, fear not. You're absolutely welcome to attend for the top-level networking and "how to get it done" discussions that can make it even more critical that you find your way there. Visit www.SSLsummit.com for series details, or jump directly the NY overview here.
