Novaled - Page 8

Update: We have found photos of the new lamps, see below

Last week we reported that Ingo Maurer will soon show two new OLED designs using transparent panels from Novaled, and today we have some more information and photos of the lamps. The lamps will use OLEDs made on glass substrates that are transparent when in the off state.

The first lamp is called Flying Future, which uses 90 "Wing" OLEDs with an active area of 30 cm². The second lamp is "4 x 4 is 34" which includes four "Quadro" (100 cm²) light elements that the user can play with. Here are photos of the lamps, thanks to the anonymous commenter:

Flying Future

Ingo Maurer, who designed the world's first OLED lamp back in 2006 (using OSRAM's OLED Lighting panels) says they will soon show new OLED designs using transparent panels from Novaled and ORBEOS panels from OSRAM.

Update: We now have photos and more details on these OLED lamps...

Novaled is working with a European car maker to develop OLED Lighting - which will be used as interior lighting in cars, and also as backlight. A car that uses these new panels is likely to enter the market in the next 2 years. They are already beyond the concept phase, and are now now planning to start production.

Novaled 15x15 cm white OLED

Novaled is set to introduce new ultra-flat and long-life OLED lighting at the Light + Building show in April 11st. The OLEDs on display will range from warm white to clear cold white, and they will also show color OLEDs (orange, red & blue) and color-tunable OLEDs (from light-blue through white to orange), too.

Some of these panels are big - up to 225 cm². The OLEDs can be transparent or behave like a mirror depending on the substrate material (metal or glass) and device structure.

Yesterday Novaled released a new animation with some beautiful concepts. We'll have to wait for April to see which of these concepts have materialized to prototypes...

Novaled released a nice movie (or animation, really) with some nice OLED Lighting concepts. The video is no longer available, but here are some of the highlights:

Update: the video has been removed, sorry.

Janice Mahon from UDC is talking with Butterscotch's Andy Walker. She's giving a very nice introduction to OLEDs, and we can also see some nice examples such as Samsung's transparent laptop and 3D OLED TV and Novaled's OLED Lighting prototypes.

Novaled and Plextronics will jointly develop doped and solution processed OLED materials. The two companies will develop an advanced solution processable Hole Injection Layer (HIL) technology for OLEDs. By leveraging Plextronics’ organic conductive ink technology and Novaled’s organic dopant technology, the companies will target these advanced HIL materials for use with solution processed polymer and small molecule emitters, as well as with vacuum deposited small molecule emitters.

Novaled and Plextronics aim to offer a solution processed HIL with the same performance as a Novaled doped small molecule HIL deposited in a vacuum process. They will co-market Plexcore OC inks that incorporate Novaled dopany materials.

Novaled announces a new 15x15 OLED device that has a 30lm/W power efficiency and 1,000 cd/m2 brightness. The OLED white light has a CIE color coordinates in line with the DOE energy star specifications. The lifetime is quoted as 20,000 hours.

The panel thickness is less than 2mm, and the light is a very high color rendering index (CRI) of 90. The perception of this light is similar to sunlight or what is delivered by incandescent bulbs. The achieved color coordinates of (0.44, 0.41) are inside the US Department of Energy (DoE) quadrangles at Illuminant A and even meet the more restrictive 7step MacAdams Ellispis around Illuminant A.

Novaled calls this new technology 'liternity OLED', which they want to start commercializing. It will allow upscaling to very large sizes.

The OLED100.eu project is a European 3-year OLED lighting project. The 30M$ project is a followup to the OLLA project, ended in June 2008, and it is lead by Philips, OSRAM, Siemens, Novaled and the Franhofer IPMS.

Dr. Stefan Grabowsky, the project's manager has been kind enough to talk to us, answer a few questions and give us more info on the project. Dr. Stefan has a Ph.D in Physics,  from the University of Duisburg. In 2000 he joined Philips Research labs. He's working on OLEDs for several years now, with a focus on device physics and OLED stack development. Since September 2008 he is the project manager for OLED100.eu.

Q: Stefan, thanks for taking the time to do this interview. Can you tell us a bit about OLED100.eu?
OLED100.eu is an European integrated research project that has brought together a consortium of experts from leading industry and academic organizations to accelerate the development of organic light-emitting diode (OLED) technologies. It has received €12.5 million funding from the European Community’s Seventh Framework Programme to form the technological basis for efficient OLED applications for the general lighting industry in Europe.

Large-area OLED from Philips

Novaled and Kodak have developed  anew white PIN OLED, to be used in RGBW displays. The display is based on Novaled's p-type and n-type doped transprot layers and Kodak's emitter systems. The companies showed two devices - single unit and tandem-white OLEDs. 

For the single unit devices, 15.8-cd/A with a lifetime of 30,000 hours and color coordinates of 0.32/0.35 at 1,000 candelas per square meter were reached. In the tandem device approach a current efficiency of 33.2 cd/A at color coordinates 0.28/0.31 was achieved. The lifetime of the device was 77,000 hours compared to 51,000 hours that were reached with devices based on conventional Li-doping for the connector unit

In a display simulation the tandem device compares favorably with a conventional tandem device based on Li-doped p-n connectors; allowing display lifetime to be improved from 38,000 to 53,000 hours.
