'Nano-paper' chips end up in compost heaps, not landfills
Today's cast-off gadgets are far more likely to end up in a landfill than they are being responsibly disposed of. In fact, 41.8 million tons of e-waste were scrapped last year alone. To combat this, a team from the University of Wisconsin-Madison has invented a radically new kind of ecologically-friendly semiconductor chip made from wood. No, seriously.
Corning unveils slim, flexible Willow Glass (video)
That is not plastic in the image above, it's glass. In particular it's a sheet of Corning's new 100-micron-thick Willow Glass, a new ultra-thin and flexible substrate for LCDs and OLEDs. The extreme thinness of the glass should lead to lighter, svelter devices, but it also means that shape is no longer a barrier for design. In fact, Corning expects Willow Glass will eventually lead substrates to be manufactured "roll-to-roll" instead of "sheet-to-sheet" -- similar to how newspapers are printed. Even though the glass is as thin as paper (literally) it doesn't give up its patented Corning toughness. Though, we wouldn't subject this to the same sort of abuse that the more brolic Gorilla Glass is built to withstand. Willow will start showing up in smartphones first, but the company is already looking into additional applications, such as solar cells and lighting. For more, check out the video and PR after the break.
Sony's new cameraphone CMOS jams bigger gear into the same space (video)
Sony's done gone and developed a new back-illuminated CMOS designed to improve the state of your casual camerawork. Traditional units mount a merged pixel-sensor and circuit on a supporting substrate -- the innovation here is to produce the two separately and layer them without any additional material. This makes manufacturing easier and without a mount, you're able to lever-in bigger kit into the same space. It's also packing HDR Movie, which like the still-image version, will produce better moving pictures in tricky light. An eight-megapixel version will ship to cellphone producers in March, with a 13-megapixel edition following in June and if Sony's really successful, it might earn enough to buy a copy of Photoshop rather than producing release images in MS Paint.
Samsung breakthrough could turn your window pane into a big ol' LED
Samsung's quest for transparency won't end with laptops, apparently. Today, the Samsung Advanced Institute of Technology announced that its engineers have successfully created "single crystalline Gallium Nitride on amorphous glass substrates" -- an achievement that would allow the manufacturer to produce jumbo-sized LEDs from normal glass, including window panes. Samsung says this scaled-up approach will allow them to lower production costs relative to most LED manufacturers, which rely on sapphire, rather than glass substrates. And, whereas most Gallium Nitride (GaN) LEDs on the market measure just two inches in size, Sammy's technique could result in displays about 400 times larger. "In ten years, window panes will double as lighting and display screens, giving personality to buildings," a Samsung spokesperson told the Korea Herald. Unfortunately, however, it will likely be another ten years before the technology is ready to hit the market. Until then, we'll just have to do our late night window coding the old fashioned way.

Samsung's new AMOLED production line should help ease smartphone display shortages
AMOLED displays may be in relatively short supply nowadays, but Samsung is doing its best to bridge the gap. Today, the company's Mobile Display unit announced that its 5.5th-generation AMOLED production line is now open, some two months ahead of schedule. The line uses glass substrates that are substantially larger than those found in its existing factories, allowing Samsung to increase output, while lowering costs. This increase in production comes in response to growing demand for the Galaxy S II and an AMOLED market that, according to DisplaySearch, should triple in value this year to $4.26 billion. For now, the production line is focusing on smartphone displays, since that's where demand is growing fastest, but will eventually turn its attention to tablet PC displays, as well. The new factory assembling the displays can currently churn out about three million screens per month, but is capable of ramping that up to 30 million, at full capacity. No word yet on when it will achieve this rate, but if SMD continues to boost its output, we may even see that market surplus we've been hearing about.
Styrofoam touches electrodes to create incredibly fast-charging wonderbatteries
Elon Musk's heart may have already given up on the humble battery, lusting after capacitors, but researchers at the University of Illinois have think there's life in the 'ol cells yet, creating batteries that charge and discharge in seconds. They've found a way to create electrodes using polystyrene beads as a sort of substrate, tiny spheres helping to set the porosity of either the nickel-metal hydride or lithium-manganese capacitor material. By adjusting the size and density of the bean bag innards the team was able to create an electrode porosity of 94 percent, which is just a few ticks short of theoretically ideal for exposing the maximum surface area of the electrode to the battery material. This results in extremely fast charges and discharges, the NiMH cell hitting 90 percent capacity in just 20 seconds and discharging in as quickly as 2.7 seconds. While we don't know just what kind of charging system the team was using to achieve this, even assuming a high-amperage stream of electrons this is still a remarkable feat. But, like most major advances there's a drawback: similar to Toshiba's SCiB batts the capacity of these cells is only about three quarters what it would be using normal battery construction, meaning you'd need roughly 25 percent more mass to get the same range in your ultra-fast charging EV of the future. That might just be a worthy trade-off.
Corning battons down the hatches for rough LCD waters
Even if the economic climate favors RPTVs for one last hurrah, things are looking grim for LCD demand -- just ask Corning, which has backed off of its previous financial guidance for the near-term future. The global economy being what it is, production from Taiwanese manufacturing plants in particular has decreased demand for the LCD glass substrates "more precipitously than expected," and similar pains are being felt at the Samsung Corning Precision Glass operation in Korea. The news gets more ominous still when the company cites uncertainty in both LCD supply chain and retail sales as reasons to decline any updated guidance for Q4 2008 or 2009. It's not all doom and gloom, of course -- this environment can play in your favor if you're in the market for a new TV.
Corning considers the color of its crystal, chooses TV glass
If you ask folks around Engadget HD to name a luxurious work of art, chances are you'll hear something like "Samsung LN70F91BD." Outside these walls, though, if you ask around a crowd of a more wine-and-cheese bent, you might get a response like "Verre de Soie Steuben Vase." Those two worlds have Corning glass in common, at least for a little while longer. On one hand, Corning is the largest supplier of glass substrates for flat panel displays. On the other, it also has a long history (since 1903) of glass artisanship in its Steuben brand. Times being what they are, though, Steuben is losing money and the flat panel display glass business accounts for about half of the company's sales, with growth expected to rise along with LCD's fortunes. Sadly, Corning is looking at either selling off Steuben or closing it down. We're hoping a buyer is found; as much as we love our TVs, we'd hate to see them associated with the end of artwork we've seen in the Corning Museum of Glass.
Samsung, LG get 2006 started off right
Does it look like April to you? Sure doesn't to me, cuz I haven't started pestering people for birthday presents yet. Anyway, Samsung's second 7G LCD production facility wasn't supposed to open till April, but they're opening today. I guess all those rumors of HDTV LCD oversupply will be coming true in the near future, because 4 screens per substrate, 45,000 substrates per month.....is a whole lot.I wonder if you drive by the plant, they have those signs like Krispy Kreme announcing fresh....LCD's?Edit: Looks like LG couldn't wait to get the party started either, as this later Reuters report mentions they are also kicking off production at their own seventh generation production facility, as we reported earlier. Geez man, before long everybody is going to have one, why buy an LCD when you can just get a whole LCD plant?From LG's press release: "LG.Philips LCD will be the only panel maker who operates both 6th and 7th generation lines, which will strengthen its position as a leader in the LCD TV market.Based on its system of fab dedication, LG.Philips LCD has developed a portfolio of facilities that concentrate on specific product categories. The 6th generation line in Gumi focuses on 32- and 37-inch TV panels while the 7th generation line in Paju will focus on 42- and 47-inch TV panels. This gives LG.Philips LCD an efficient production base, and will allow it to continue its leading role in the global standardization of LCD TV sizes."
