Researchers achieve new efficiency record of blue OLEDs

by Darren Murph posted Dec 23rd 2008 at 3:55PM

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.

South Korean scientists claim development of "true blue" for OLED displays

by Darren Murph posted Nov 24th 2008 at 3:52AM


It's no secret that OLED gurus have had the toughest time improving the life of blue luminance to match the lifespans of its red and green counterparts, but a team of South Korean scientists have purportedly stumbled upon (or developed, as it were) a breakthrough "true blue" material that can "accelerate the development of next-generation organic light-emitting diode (OLED) displays." Up until now, scientists have been able to create highly efficient green and red OLED materials, but the inability to make a true blue OLED material was really holding things back. So, now that this little hurdle has been hopped, how's about we get some big screen OLED HDTVs out to the people?

Canon develops pair of LCoS reflective LCD panels

by Darren Murph posted May 21st 2008 at 10:58AM


Though Canon has been focusing on SED and locking down LCD partnerships throughout the earlier part of the year, the firm will be showcasing its very own LCoS reflective LCD panels at InfoComm next month. The first panel is a 0.71-inch WUXGA (1,920 x 1,200) model, which is said to be the "world's first LCoS panel of its size to achieve such a level of resolution." The second is a 0.55-inch SXGA (1,400 x 1,050) version, which can also be used in conjunction with other Canon technologies to bring new projectors to market. Beyond that, it seems we'll have to wait until June before finding out more, but you can certainly peek the read link and attempt to read between the lines.

LED / LEC hybrid lights could infiltrate flat-panels

by Darren Murph posted Mar 20th 2008 at 9:45AM


As if you didn't have enough display technologies to wrap your noggin around, here comes yet another dark horse around turn three. Reportedly, researchers in California have "developed a hybrid light that is cheaper, longer lasting, more energy efficient and is as bright as traditional light emitting diodes (LEDs)." Interestingly enough, the resulting light actually blends the aforementioned LED technology with newer light emitting electrochemical cells (LECs) in order to create a hybrid light that would play nice in flat-panel HDTVs. LECs by their lonesome have experienced lifetime issues in the past, but the new combination seems to nix that quirk altogether. Not surprisingly, there's no word on when this discovery could actually find its way into the commercial display realm, but here's to hoping it fares slightly better than the ill-fated SED.

DuPont unveils host of flat-panel HDTV technologies

by Darren Murph posted Jun 8th 2007 at 2:35PM


While we knew the company famous for bringing miracles of science into our daily lives was lending a helping hand with OLEDs, a recent announcement has detailed that the company plans on getting into a whole lot more than just that. Among the technologies it hopes to integrate into tomorrow's flat-panel displays are thermal color filters, direct bonding, Optilon anti-reflective coatings, advanced composite reflectors film for improved luminance, Drylox, and a smattering of niceties around field emission displays. Of course, there's way more here than we could possibly cover in this space, so do your curious mind a favor and dig right in to the detailed read link.
