OLED Lighting

One of the more fun new technologies I saw at the TED conference this week was a demo of the newest form of 3-D film, seen behind glasses from RealD Cinemasony-glasses1These are the RealD glasses they gave us at TED.  They work and with no dizziness, headache, or other bad side-effects.  We saw a sampling of concerts (Bono), music videos, sports events, etc., all in 3-D, and the images were realistic and truly fun to watch.  There were a few gimmicky moments, such as when Bono extended his hand forward and it hovered as if outside the frame of the screen.  But overall, the effect of the 3-D simulation drew the viewer more into the experience of the film-making.  The best use of the 3-D in my opinion was for sports games. It was very cool to see football in 3-D for instance. I’m sure my football-playing son and his friends would love to watch games in 3-D if they couldn’t be there live.

As I’ve written about before on this Blog, OLED televisions are coming soon and in combination with the 3-D simulation, this will revolutionize the television watching experience exponentially.  Sony OLED television is likely to lead the way and Sony partnered with RealD Cinema on the TED presentation.  I can only imagine what RealD and Sony will accomplish together for full-size film experiences.  Their partnership may revitalize in-theater movie watching more than anything else has in a long time.



 Sony Bravia XEL features an OLED screen, measuring just 3mm thick

World's thinnest TV ? slimmer than a pound coin, but costing 3,489 of them   

The world’s thinnest television goes on sale, measuring a mere 3mm, no thicker than a penny, but costing thousands of them.

Sony’s Bravia XEL promises to transform the television industry, despite its high price, by offering viewers the crispest, most colorful pictures ever seen. Because it has such a lightweight screen, Sony predicts the Bravia XEL model will revive the idea of portable televisions, with users being able to move the TV from room to room like a laptop.  Indeed, the Sony will give portable and easily used laptop television a run for the money.

The XEL is the first Organic Light Emitting Diode (OLED) television to come to market and uses completely new technology from previous flat screen models such as LCD and Plasma.

Normal flat screen televisions use a backlight to produce the picture on screen, but OLED screens actually emit their own radiance, which means the blacks are pure black, rather than the dark grey you get on most televisions.  All those who see and compare OLED TVs to even the best of LCD and Plasma gasps at how realistic OLED  is. Indeed, OLED has been described by many as being BETTER than reality.

The contrast ratio on a good LCD television is about 30,000 to one. On the OLED it is 1 million to one.

OLED televisions were first unveiled as a prototype a year ago, but Sony is the first company to start selling them to consumers. However, because the technology is still so expensive and fragile, the biggest screen available is just 11 inches wide.

What is the excitement over OLED?

Well, it's extremely thin, light and durable — it may also be able to provide better images, use less electricity and come far cheaper than today's display technologies.  When you see OLED televisions, they are so bright and sharp, they're almost better than reality.

2009 CES was subdued this year due to the economy.  Many former exhibitors didn't show up this year, preferring to communicate with the public via email and press releases.  2009's advances are not that great.  In the OLED area, there are a few new screen prototypes that are worth mentioning. That's about it.


The most innovative of the OLED new screen designs are small and flexible, the sort of screens you might on cellphones or wristbands.

Sony has a new OLED screen that can be bent over like a piece of paper, and keeps displaying it's images. This is pretty cool, but not much different than the flexile OLED screen I was handed at the  TED conference (Technology, innovation and design) conference in 2006 (by Innovative).  

Samsung showed off a cellphone proptype that opened up like a book to reveal a large screen, also made of flexible OLED material.

Universal Display Corporation showed off the most impressive of all the prototypes — a video monitor embedded inside a wristband. Here's a photo:

In the OLED TV are, LG presented a 15 inch OLED model that measured less than a millimeter thick.  LG promises to have a commercial OLED TV model — albeit one that will measure a hefty 1.5 millimeters thick — available by this summer.

Sony, the only company that currently sells OLED televisions, showed off a 21 inch model, but did not say when it will hit store shelves.


Current OLED TVs are very expensive.  Sony sells an 11-inch OLED for $2,500. Prices will come down steadily though; OLEDs are the future.  Soon, manufacturers will be able to print OLED displays on continuous rolls of plastic.  That will be much cheaper than making screens in small batches.  When that happens, watch out! OLEDs will be the next leap forward

OLEDs are organic light-emitting diodes. In OLEDs, white light is generated by using electricity to send an electron into nanometer-thick layers of organic materials that behave like semiconductor materials. Typically, the light in the substrate is internally reflected and runs parallel and not perpendicular. That’s the crux of the problem because the light can’t escape in the vertical direction without some coaxing. In certain devices, the grids refract the trapped light, sending it to the five micrometers dome-shaped micro lenses. The light is sent off in a vertical orientation that helps release the trapped rays. Better and cheaper OLEDs can mean greener flat screens and light sources.

Until recently, OLEDs were made that produce 46 lumens per watt. Now researchers at the U. of Michigan and Princeton claim to have made OLEDs that can produce 70 lumens per watt (compared to 15 lumens per watt for incandescent), To achieve this impressive efficiency, the researchers are using a grid combined with micro-lenses, all of it on the nano-scale (the lenses are 5 micrometers wide).

We at LEDInsider.com keep up to date on the latest advances in LED technology to be able to bring you the best and most efficient options for your lighting needs.

Organic light emitting diodes (OLEDs) look very promising. They are more efficient than incandescents without the downsides of CFLs (mercury, fragile) and they have the potential to become less expensive than regular LEDs. Because of their thinness and flexibility, OLEDs also hold the promise of being used in all sorts of applications.

OLED technology is developing rapidly, although it’s not ready for us to sell to you at http://www.LEDInsider — yet!

In late 2005, Osram announced “a breakthrough in polymer-OLED technology by achieving a record 25 lumens-per-watt (lm/W) of device efficiency”. Now, they are announcing that they manufactured warm white OLEDs with an efficiency of 46 lm/W and a life of more than 5000 hours at a brightness of 1000 cd/m2. That’s close to the efficiency of CFLs, and more than twice that of incandescent lamps.

At LEDInsider, we are committed to bringing you the best and latest technology at the best prices. As soon as we can sell you OLEDs, we will have in on our website – http://www.LEDInsider.com. If you go to the website and sign up to receive notices of new developments, you will be the first to know when we can sell you OLEDs

OLEDs (Organic Light-Emitting Diodes) are paper-thin, flexible sheets of polymers or plastic materials that illuminate when an electrical charge is applied. A key advantage of OLEDs is that they are flexible so that they can be incorporated into things like clothing, wallpaper, refrigerators, cars.

General Electric Global Research has been working on OLEDs for the last decade. In 2003, GE came out with a 2’x2′ OLED light source. For a behind-the-scenes look at what is going on, check out this recent blog post by one the GE engineers involved in OLED development. http://www.grcblog.com/?cat=19

The world renowned lighting designer Ingo Maurer has developed the first organic LED OLED lamp from OSRAM in a function table light. The light, known as “Early Future”, is being produced as a limited edition of 25. It uses 10 OLED light panels, sized 132 x 33 millimeters. The OLED bulb in this lamp are actually thin square sheets…This lamp is actually more of a prototype – only 25 will be made.It works with tiles straight from the laboratory and demonstrates the enormous potential of OLEDs for future applications as eye-catching illumination and design elements.

OSRAM Opto Semiconductors made prototypes of OLEDs available to the Ingo Maurer for his exclusive creation. “We are proud that our OLEDs have inspired such a renowned artist as Ingo Maurer to create such an exciting work of art. “Early Future” is a vision that has become reality. It gives us a glimpse of just how versatile organic OLEDs can be in terms of their design options and applications”, said Martin Goetzeler, CEO of OSRAM.

The panels on Maurer's light have a lifetime of 5,000 hours (up from 2,000), and OSRAM says that these lamps will be available by 2011 or 2012. The efficiency is 46 lm/W (1000 cd/m2).

OLEDs – a journey from the laboratory to the home
Organic LEDs offer all the familiar benefits of LEDs such as high energy efficiency, low operating voltage and mercury-free design, and have some impressive properties of their own. The light source is not a collection of individual light points but
a uniform light-generating surface. Initial laboratory prototypes from OSRAM showed last year the property of transparent light in a usable tile size
. Thanks to the layer structure, it is possible to produce not only very thin OLEDs but also scalable ones.

OSRAM Opto Semiconductors has a team of around 50 research engineers working on the development of OLEDs.  “In the future it will be possible to use OLEDs as flexible or transparent light sources. A transparent OLED over a window in a roof would be able to allow natural light in during the day and provide fascinating illumination for the room at night”, said Dr. Bernhard Stapp, Head of Solid State Lighting at OSRAM Opto Semiconductors. 

At LEDinsider, we eagerly await being able to offer you OLED lights and will just as soon as they are available in a high quality, reasonably priced option.
