Universal Display and Fraunhofer IPMS – COMEDD – announce OLED material agreement for white OLED lighting
23 April 2012

Fraunhofer IPMS – COMEDD (Center for Organic Materials and Electronic Devices Dresden), a unit of Europe’s largest application-oriented research and development organization, and Universal Display Corp. have announced an agreement for Universal Display to provide its proprietary phosphorescent OLED materials as a key ingredient for driving energy efficiency in COMEDD’s white OLED lighting panels.

In this new two-year agreement, COMEDD will develop and fabricate energy-efficient, white OLED panels for market development.

Prof. Karl Leo, director of the Fraunhofer IPMS – COMEDD, said, “The contract with Universal Display allows us to realize OLED lighting devices using the leading phosphorescent emitter technology. This is a key step toward increasing the efficiency of white OLED to levels where broad market acceptance can be reached.”

Steven V. Abramson, President and CEO of Universal Display, said, “We are delighted to work with Fraunhofer IPMS - COMEDD, a leading European research institution in white OLED panel development. The work that Fraunhofer is performing at their Center for Organic Materials and Electronic Devices may help accelerate the commercialization of energy-efficient white OLED lighting products.” Steven added, “We look forward to supporting COMEDD with our ‘all-phosphorescent’ solution for its development and demonstration of OLED lighting panels with enhanced energy efficiency. Through programs like this, we believe that we can contribute to forging a more energy-efficient, environmentally sustainable future for Europe, the U.S., and the world at large.”

Georgia Tech publishes research on stable low-work function electrodes
16 April 2012

Making say an OLED or organic photovoltaic device require conductors, usually calcium, magnesium or lithium, that have a low-work function. However, these metals are chemically very reactive, and oxidise and stop working if exposed to oxygen and moisture. To overcome this organic photovotlaics must be encapsulated either via another sheet of glass or by a thin-film encapsulation technique. Both of these approaches increases material costs, and makes it more difficult to produce truly flexible devices.

However, a research team from the Center for Organic Photonics and Electronics (COPE) at Georgia Tech have recently published in the journal Science what the researchers believe could be a universal technique for reducing the work function of a conductor. This would reduce the need for using reactive metals for electrodes.

The approach involves spreading a very thin layer of a polymer, approximately one to 10 nm thick, on the conductor’s surface to create a strong surface dipole. The interaction turns air-stable conductors into efficient, low-work function electrodes.

The commercially available polymers can be easily processed from dilute solutions in solvents such as water and methoxyethanol.

To illustrate the new method, the research team evaluated the polymers’ performance in organic thin-film transistors and OLED devices. In addition, the team build what they claims is the first “completely plastic” photovoltaic.

LG Display opens new research and development centre in Paju
16 April 2012

LG Display has announced that the company has officially opened a research and development centre that will focus on developing next-generation display panels, including the OLED based displays, in Paju, Gyeonggi Province. About 2,500 workers are expected to complete their relocation to Paju by May.

According to an LG Display executive previously the company’s R&D workforce where based across several different research facilities spread across the country. By bringing together everyone into one single location it is hoped that LG Display will reap the benefits of co-located research as they focus on accelerating the development of next-generation displays.

Han Sang-beom, CEO, said, “It’s a pleasure to open up a new R&D space for the talented workers of the display industry, where they could work on projects with their passion.” Han Sang-beom, added, “We’re planning to lead the next-generation display market by transforming our Paju R&D plant into a mecca of high-tech display technologies such as OLED, e-paper and ultra-high resolution AH-IPS displays.”


OLED lighting gathers momentum as European luminaire manufacturers embrace OLEDs
16 April 2012

At the recently held Light & Building 2012 there where many OLED panel manufacturers and luminaire manufacturers using OLED panels than seen at Light & Building 2010. While a number of device manufacturers chose the exhibition to launch new OLED lighting panels and it was the growth in the number of luminaires manufacturers who also announced that was the real indicator of commercial progress at the show.

It is clear that the major lighting companies Osram and Philips are making substantial efforts to push OLED panels on to the market. Each company dedicated a significant section of their stand to OLED lighting. Both companies chose to show “art” based OLED luminaires along with the standard product lines. Philips took the opportunity to announce the latest addition GL350 while Osram introduced the Orbeos SDW-058. It is interesting to note that Philips has moved to using the company’s naming convention rather than use the Lumiblade name.

Luminaire manufacturers such as Tridonic devoted substantial amounts of stand space for the OLED lighting. In previous shows LEDON OLED was used for branding the OLED lighting – however it would now appear that all lighting, OLEDs included, are being marketed under the Tridonic brand name for the foreseeable future. Their influence spread further as they promoted six of their customers who where using OLED panels supplied by Tridonic. These where luminaire manufacturers - Selux, Ridi, Ludwig, Spittler, Hatec and IDL and these all used square panels with the exception of Ludwig who presented a circular luminaire that used round panels. Selux in association with ART+COM presented the beautiful and almost magical Manta Rei – a kinetic luminaire based on the use of 140 OLED panels. This animated luminaire appeared to glide effortlessly and majestically through the air, although it was securely attached to the ceiling. Although the Manta Rei maybe considered as art it can be purchased in one of several different configurations.

European luminaire are beginning to show first OLED products and while many are destined for commercial sale it is nonetheless a strong indicator that OLED lighting is becoming an important addition to their product range. Several of the luminaire companies I spoke with said they needed to demonstrate they where working with OLEDs for next generation products.

The increasing umber of luminaire manufacturers using OLED – even for one off products can be seen as an indicator that OLED lighting is gaining attention and worth spending significant sums of money to construct luminaires that demonstrate the attributes of OLED.

Unlike other OLED technology providers and device manufacturers Novaled chose to present themselves as a luminaire manufacturer – operating under the Liternity brand name. The stand showed the Victory table lamp, the company is focused at the luxury end of the market as each lamp is hand-made and therefore unique. There other products on show where branded Linfinity, Trinity and Lucentury. All three luminaires used OLED panel where transparent when switched-off. Giving an interest visual appearance in their off-state, as the lamps almost disappeared as they blended into their surroundings.

No pictures: Unfortunately I left my camera behind at the hire car rental desk with all my pictures from the show. I have been informed by the hire car company the camera has been posted back to me. So I’ll compile a follow-up show report focusing more on the technical details for next weeks’ newsletter and hopefully be able to include pictures.
