ViewSonic PLED-W200 DLP pico projector hands-on
Just two days ago, we brought you word of a Texas Instruments powered pico projector by ViewSonic. We found the 0.9-pounder and snapped some pics of an (unfortunately) non-functioning unit. It features a 4-in-1 card reader, mini USB cable, and adapter for an included dongle that supports VGA and composite cables. With a 1280 x 800 WXGA resolution, the 200 lumen bulb is LED-based and has a lamp life of 20 to 30 thousand hours. The scrolling wheel, that you can peek at in the gallery below the fold, rests atop the projector and focuses the image. As for size limitation, the rep said up to 300 inches. The company said it'll retail at $479 when it ships in April. %Gallery-113303%
Researchers tout better, brighter LEDs
A pair of researchers at UCLA's Henry Samueli School of Engineering and Applied Science seem to think they're well on their way to building a better LED -- one that's not only brighter than existing LEDs, but more energy efficient and less expensive to boot. According to Physorg, the team's biggest success so far is red phosphorescent LED (or PLED) that delivered a record-breaking 18 lumens per watt (compared to an average of 12 lumens per watt with current red LEDs). The key to that, it seems, was to simplify the LED as much as possible, which they did by adding a polymer powder and liquid mixture to a "previously top-secret material" developed by Canon. The resulting "paint-like product" was then used to coat a layer of glass, with a charge then added to get the whole thing going. From the sound of it, these new wonder LEDs should be making their way into consumer products sooner rather than later, with Canon (naturally) reportedly already having licensed the technology and the first commercial products expected in "about three years."
