  • TDK starts mass production of transparent OLEDs, makes texting and walking safer

    TDK is taking those transparent OLED screens we saw back in October and putting them into mass production. The 2.4-inch, QVGA (240 x 320) UEL476 display has a transmittance of 40 percent, but obscures light passing through the front so others won't be able to read your text messages from behind. Obviously, these aren't going to find their way into high-end Android handsets, but they may have a home in fashion phones like Lenovo's S800. And, you know, they seem perfect for SMS addicts who can't stop their thumbs from flying even while walking. Check out the full PR after the break.

  • TDK's see-through and curved OLED display eyes-on (video)

    Remember the Sony Ericsson Xperia Pureness? At a list price of $1,000, it'd be hard to forget -- but with a monochrome see-through display, the whole transparency thing was little more than a novelty on a phone that served little practical purpose. TDK might have the solution with its new transparent QVGA OLEDs, available now to manufacturers in monochrome and in a lovely color variant by the end of the year. At two inches, they offer 200ppi pixel density and are more secure than you might think: the light only shines in one direction, so you actually can't see any data from the back even though you can still see through the display. At a glance, the display's didn't seem as vibrant as the best AMOLEDs on the market, but then again, these are passive matrix -- and you can really tell in our videos after the break where the refresh scans stand out. Guess that's the price you pay for transparency, right? We've also got some video of the 3.5-inch flexible OLED screens TDK's got on hand; they're not transparent, but considering the long, narrow resolution, we can't help but think they'd make for amazing wristwatches (or high-tech glowstick replacements at raves). %Gallery-104249%

  • Samsung SDI to back away from PMOLED, focus efforts on AMOLED

    Unbeknownst to most, there are actually quite a few flavors of OLED out there. We've got passive-matrix (PM), active-matrix (AM) and transparent, and evidently Samsung SDI isn't really feeling the former anymore. Reportedly, the outfit will begin to phase out of the PMOLED business, and it will begin looking for ways to alter its existing PMOLED production line for "other uses." The plug is being pulled (at least partially) as decreasing panel prices and a small bucket of buyers have reduced profitability, leaving it little option but to readjust its focus on the more promising AMOLED. The move isn't entirely surprising -- after all, LG Display suspended its entire PMOLED business last year, and while there is a slight possibility that the firm keeps a small bit of PMOLED production going, it'll be minor (if there's any at all). Our take? We're stoked. It's the AMOLEDs that'll end up in that mythical 40 inch (and beyond) OLED HDTV, so we're all about giving more attention to that baby's commercialization date.
