    The holy grail of OLED is upon us. With scientists around the world working to improve efficiency of the short-lived blue OLED in order to better align with lifespans of the green and red counterparts, a team from Pacific Northwest National Laboratory has reportedly taken a huge leap in solving the whole thing. These gurus have conjured up new host materials for a blue phosphorescent OLED that's at least 25 percent more efficient than existing blue OLEDs, but regrettably, details beyond that are few and far between. Word on the street has it that PNNL scientists are expected to gather and discuss the findings before heading to a meeting of the American Chemical Society later this spring, and we'll be crossing our fingers that whatever they've found is both a) cheap and b) easily implementable.[Via OLED-Display]

  • Researchers achieve new efficiency record of blue OLEDs

    Ever since Sony's XEL-1 hit the market, pundits have pointed to the (comparatively) short-lived blue OLED material as its biggest hamstring. Researchers have been toiling around the clock in order to bring the blue lifepsan in line with its green and red siblings, and now it seems like a team of Gators are that much closer to the promise land. Reportedly, a gaggle of whiz-kids from the University of Florida have "achieved a new record in efficiency of blue organic light-emitting diodes, and because blue is essential to white light, the advance helps overcome a hurdle to lighting that is much more efficient than compact fluorescents." Franky So (pictured) and his diligent crew were able to reach a peak blue OLED efficiency of 50 lumens per watt, which is halfway to his goal of at least 100 lumens per watt. Hurry it up, folks -- CES is just around the corner.[Via Physorg]
