Aixtron is to take part in the OPAL 2008 (Organic Phosphorescent lights for Applications in the Lighting market 2008) R&D project in a consortium with Osram, Philips, BASF and Applied Materials. The project will use Aixtron's Organic Vapor Phase Deposition (OVPD) technology platform.

OPAL 2008's aim is to develop OLED production technology capable of achieving a target cost of a few Euro cent per cm² for a high performance white OLED device, with the ultimate goal of introducing the new lighting technology into the market.

With the Joint Innovation Lab (JIL) BASF is opening a research laboratory for organic electronics in Ludwigshafen on September 11. BASF will conduct research at the JIL with both industrial and academic partners into new materials in the field of organic electronics.

At present the JIL researchers are concentrating on organic light emitting diodes (OLED) and organic photovoltaics. OLEDs are flat, thin light-emitting devices made from organic semiconductive materials. As lighting panels, they offer completely new options in lighting technology, such as windows as transparent light sources or credit card sized flashlights. The researchers have calculated that in their current form OLEDs are likely to consume less than half as much power as conventional fluorescent tubes. OLEDs also have a long lifetime.

In this area, BASF Future Business GmbH has launched the project "OLEDs for appliances in the lighting market" (OPAL) together with partners from industry such as OSRAM, Philips, Aixtron AG and Applied Materials. The goal of the project is to create the scientific and technological basis for initiating the production of OLED-based lighting in Germany.

Philips and Novaled reached a new record for the power efficiency of a white OLED, obtaining 32 lm/W with colour coordinates of 0,47/0,45 and a CRI of 88 at a brightness of 1000 cd/m2. That same device structure thereby simultaneously shows a lifetime of more than 20000 hours which is a major achievement for a future commercialization of the OLED technology for lighting applications.

The efficiency of the device was measured using an integrating sphere using only the forward emission cone of the OLED device without attaching any lens or any other volume type luminaire to the OLED device. This is the only method to reliably predict power efficiency values for large area lighting tiles.

Novel display technologies will complement LCDs, OLEDs, and plasma technologies at the 44th Society for Information Display Conference to be held in San Francisco, June 4 to 9.

One of the most intriguing new technologies is Liquavista, a spinoff from Philips launched in April, which is developing products using electrowetting technology for portable displays.

DisplaySearch indicated in its latest Quarterly OLED Shipment and Forecast Report that OLED shipments grew to 14.2M and revenues hit $124.8M in Q2'05. OLED displays compete with LCDs in small/medium applications such as mobile phone main displays and subdisplays, MP3s and automotive consoles. OLED shipments increased 82% Y/Y due to 95% growth in main display sales, and 1,300% growth in MP3 player displays. All of the growth is in PMOLEDs using small molecule material; AMOLED producers--Sanyo Kodak, AUO and Sony--shipped less than 50K displays in Q2'05. PLED material panel producers dropped to two suppliers as Philips sold their facility to OTB and now represent less than 3% of the total shipments.

Samsung SDI led in units and revenue in Q2'05 with slightly over 3.8M displays shipped and $37.2M in revenue. RiTdisplay was #2 in both shipments and revenue. LGE experienced the strongest growth of the top five, with shipments up 111% Q/Q to 740K and revenue growing 92% Q/Q to $6.5M.

The Top five applications are Subdisplays, MP3, Car Audio, Main Displays and Auto Consoles.

Philips NV has signed a deal to sell its PolyLED unit to OTB Display, a company specialising in developing and building manufacturing lines.

Philips New Displays CEO Harrie Brunklaus said in a statement that PolyLED "did not become as viable as we expected within an acceptable period of time."

A Philips spokeswoman commented to AFX News that it was better to sell PolyLED "at this time," adding that the technology provided by PolyLED "no longer fitted into our displays strategy." She also said that the sale does not mean a shift in Philips' strategy.

Philips and German firm Novaled have announced white OLEDs operating at a brightness of 1000cd/m² with a record-breaking efficiency of 25lm/W.

work between Philips’ Lighting and Research divisions, and Dresden-based Novaled, combined Philips’ materials selection, optical outcoupling technology, and layer schemes for building up OLED devices, with proprietary doping technology from Novaled.

This is an encouraging result that clearly demonstrates the potential of OLED technology for lighting applications, said Klaas Vegter, chief technology officer of the Lamps business group at Philips Lighting.
The results of the research will be used in future developments, ongoing projects, and the recently started European project OLLA (Organic LEDs for Lighting Applications), in which both companies are involved.

The government has already started up a €100 million ($130 million) initiative to support research and production of OLED's. Firms like Merck, Osram, Philips and Samsung have pledged to invest over €500 million.

Cambridge Display Technology (CDT) announced that the EU-funded STEPLED project has concluded - with "outstanding success". The STEPLED project was undertaken with the aims of understanding the science which controls the spin states of polymer-based OLED (PLEDs), critical to developing more power efficient displays.

The STEPLED project focused on establishing high efficiency materials using high singlet-ratio fluorescent polymers, but also worked on soluble phosphorescent emitter. CDT said that STEPLED achieved the production of a standard two-layer device structure with an external quantum efficiency (EQE) of 6%. This has been described as 'outstanding', being almost twice the efficiency of previous materials. The impressive performance was achieved using red emitting polymers, typically the lowest efficiency color in RGB displays.

The EU launched a new OLED lighting product (as part of the 6th framework) called OLLA. This is an integrated R&D project to advance OLED technologies with a goal to demonstrate (in 2008) high-brightness white OLED light tiles for use in general lighting applications, with a long lifetime and high energy efficiency.

The OLLA consortium consists of 24 partners from 8 European countries, lead by Philips.
