A PHOLED Ceiling Tile

The Universal Display Corporation released a video about their phosphorescent organic LED (PHOLED) ceiling tile recently – it’s an OLED using the principle of electrophosphorescence to efficiently convert electricity into light.  UDC and Armstrong World Industries is getting two million bucks over two years to work on this project – I expect good things.

About the project video, which is below the quote:

This video demonstrates a highly energy-efficient OLED white lighting panel concept for use in commercial or residential lighting. Universal Display and Armstrong World Industries developed this device, in part through support by the U.S. Department of Energy’s Solid State Lighting program, to demonstrate the potential energy-savings and other exciting features of solid-state white OLEDs for lighting.

Power-efficient white OLED lighting may reduce energy consumption dramatically and also lower the amount of by-product heat from the light source. Enabled through the use of Universal Displays PHOLED technology, energy-efficient white OLED lighting are a key element to the U.S. Department of Energys solid-state lighting initiative to help reduce worldwide energy burdens created by lighting, a significant consumer of energy. White OLEDs are also environmentally benign, especially compared to mercury-containing fluorescent lamps and newer compact fluorescent lamps (CFLs). Combining these important green features with a very thin, lightweight and durable form factor, white OLEDs offer significant new lighting design opportunities, such as the one envisioned in this ceiling system concept.

Thanks, OLED-Info!

OLED Demo – Hey, Should I Get A Hole Punch?

GE’s research lab working with OLEDs made a short video of some interesting OLED durability “tests” for all to see.  Now every solid state device needs to come with a hole punch and some scissors so I can cut light into pieces.

<chirp, chirp>

I’ll be right back, I have to run to the joke store and return that glistening piece of crap I just laid on you.  Check out this video:

You Fade to Light

You remember Chris O’Shea?  Chris worked with Cinimod Studio to create a work called Beacon a while back.  Chris just did some more programming on another work, this time an OLED love fest with Philips’ LumiBlade OLEDs and a company in London called rAndom international.  “You Fade to Light” is a project that takes your image and essentially reverses it in large OLED pixels as you pass in front of the interface.  Of course it also makes the exploit of LumiBlade’s ability to be transparent.  Of course.

Check out a video of the work:

Philips is Shipping LumiBlade Samples

Philips now has a section of their website to order samples of the LumiBlade OLED line – all kinds of shapes, a small selection of colors, all with a power supply. This is a very, very cool product, as many of Philips’ products happen to be, and I like it.

I will say this, and it’s going to come across as negative – but I hope you have better luck getting through to them than I did.  I sent four emails and left two phone calls about LumiBlade, and didn’t get as much as a “go stick it up your rear, lighting blogger.”  Funny enough, I had the possibility for a very, very large lamp supply for a project; I called Philips one afternoon, and after being sent around to six different phone numbers and having about seven people tell me they couldn’t help get us to the right department, I decided that maybe Philips wasn’t the right company for my (and my client’s) needs.  It’s too bad – I think the Master LED is pretty great.

Okay, frustrated writer rant over.  Check out these pretty great LumiBlade OLED designs:

NovaLED Unveils Ultra-Stable OLED

novaled-oled-light

A German company called NovaLED will be revealing what they’re calling a “fault-tolerant OLED” at Finetech Japan in May.  The NovaLED OLED will apparently be resistant of electrical shorts and faults which have, in its short history, killed other OLEDs.  The NovaLED OLED is intended for large area illumination or long maintenance cycle applications.

From the press release:

Dresden, Germany, 14th April 2009

Novaled AG, leading technology and material provider for a new generation of lighting and display products, will introduce a novel defect tolerant OLED structure at Finetech Japan in Tokyo from 15th to 17th April 2009.

Novaled’s Defect Tolerant OLEDs maintain the appearance of a homogeneously lighted-up surface even in the case of electrical shorts, thanks to the use of its proprietary electrode design. One OLED element consists of two comb-shaped interlocked electrodes, which give a uniform light emission. If a short in one of the stripes appears, the resistance of the stripe will limit the current flow and prevent a further rise of current and temperature, which would otherwise destroy the OLED.

“OLED devices based on the new Novaled structure are well suited for large area lighting or other lighting applications which require a long maintenance cycle”, says Gerd Guenther, VP Marketing and Sales of Novaled AG. ”We are looking forward to presenting an OLED-wall demonstrator at the Novaled booth illustrating the concept of the Novaled defect tolerant structure. The topic will be also discussed in the talk of Mr. Philipp Wellmann of Novaled at Lighting Japan.” Further demonstrators like the Victory OLED Lamp with Novaled PIN OLED® inside will be exhibited to introduce possible lighting applications.

In time for the Lighting & Finetech event Novaled is going to launch its web site in Japanese and Korean languages underlining the importance of the Asian markets.

About OLEDs
OLEDs (organic light-emitting diode) are semiconductors made of thin organic material layers of only a few nanometers thickness. They emit light in a diffuse way to form an area light source. In a fast growing display market OLEDs are key part of a revolution: the dream of paper-thin, highly efficient displays with brilliant colors and great flexibility in design. OLEDs represent the future of a vast array of completely new lighting applications. By combining color with shape, organic LEDs will create a new way of decorating and personalizing personal surroundings with light. At the same time OLEDs offer the potential to become even more efficient than energy-saving bulbs.

About Novaled
Novaled AG is a world leading company in the OLED field specialized in high efficiency long lifetime OLED structures and an expert in synthetic and analytical chemistry. The company offers complete solutions to the organic electronic markets, commercializing its Novaled PIN OLED® technology along with its proprietary OLED materials.

Now With 25% More Blue OLED Output

pnnl_light_lab_041-copy-copy

While I was digging around over at the DoE website, I discovered that there’s been a small breakthrough on OLED output.  OLED technology has been lacking a real solid blue in research so far, and the folks at the Pacific Northwest National Laboratory have gotten a 25% increase in blue light output from a blue OLED.

From the PNNL press release:

Lighting consumes one-fifth of the electricity generated in the United States. Solid-state lighting offers tremendous potential to improve the situation – once major research challenges are overcome.

The most promising technology is the organic light-emitting diode, or OLED. These multi-layered devices produce light by running an electrical current through a specially engineered host material into which light-producing phosphorescent molecules are embedded or “doped.” The white light envisioned for large-scale applications, such as rooms and buildings, consists of red, green and blue light.

“The weakest link in OLED research is the absence of an efficient, long-lasting blue light to accompany the red and green,” said Pacific Northwest National Laboratory scientist Asanga Padmaperuma. Development of better host materials to manage the flow of electricity through the device could help solve that problem.

Padmaperuma and his collegues have designed, synthesized and tested new materials that improve the power efficiency of blue OLEDs by at least 25 percent.

Modistech’s Ultra-Thin Flexible OLED

It’s been said that OLEDs are going to hit their party day some time in 2011, but a company called Modistech has started having those drinks that you have at home before the tavern.  Modistech has developed a super-thin, flexible OLED panel that looks pretty awesome.  There are not a lot of details right now on their product, but the price figure is about $213.00 USD per square meter – about 300,000 South-Korean Won.

OLED100.EU

OLED Info, one of the blogs I read, posted an article and the video above about OLED100.EU – which is a European standards group fighting to develop efficient OLED technology for use by the European Lighting industry.  After I watched the video, I didn’t know much abotu OLED100.EU, so I dug into their website a little and found out more on what they are interested in gaining.

OLED100.EU wants to establish, in OLED technology:

  • a 100 Euro or less cost per square meter of OLED
  • more than 100,000 lifetime hours for OLED sources
  • a unit area of 100cm x 100cm
  • 100 lumens per watt efficiency
