DOE announces US$10 million of new investments to drive cost-competitive OLED and LED lighting
03 June 2013

The U.S.DoE has announced two OLED lighting manufacturing research and development projects to support energy efficient lighting products. The projects will focus on reducing manufacturing costs, while continuing to improve the quality and performance of organic light-emitting diodes (OLEDs).

While life-cycle costs are attractive, the initial price OLED lighting is currently higher than the price of traditional lighting. The projects announced today will help achieve significant cost reductions in manufacturing equipment and processes, while improving lighting quality and performance

OLEDWorks : $1 million investment

The OLEDWorks project will develop and demonstrate new spray printing equipment that reduces overall manufacturing costs and could help support cost-competitive mass production. This technique will give manufacturers greater spray control to take full advantage of expensive organic materials and maximise the visible light produced from this material.

CPI produces large area small molecule and polymer OLED lighting demonstrators
03 June 2013

Researchers at the UK's Centre for Process Innovation (CPI) have recently produced defect free OLED lighting demonstrators with emissive areas of greater than 250cm2.

The device structure produced is hybrid in construction consisting of a solution processed hole injection layer, and a small molecule emissive layer deposited by a co-evaporation technique.>/p>

Slot die coating technology has been utilised to provide a large area, defect free, thin film coating. An encapsulation process utilising glue dispense and getter placement completes the panel assembly to maximise lifetime and device performance.

Philips to license OLED display patents
03 June 2013

Intellectual Property Exchange International, Inc. (IPXI) has recently announced that it will conduct two public web presentations on June 5 that will unveil IPXI's first Unit License Right (ULR) contract offering, present important offering details and launch the marketing campaign for the ULR contracts.

This first-of-its-kind offering will enable operating companies, investors and other market participants to buy and sell ULR contracts covering a large portfolio of more than 600 patent assets, including 225 issued patents worldwide, related to organic light-emitting diode (OLED) technology for display screen applications. The portfolio is the result of nearly 20 years of research in the field by Koninklijke Philips N.V. (Philips).

Sumitomo Chemical shows printed flexible OLED panel
03 June 2013

According to a Tech-On news report Sumitomo Chemical recently exhibited a flexible printed OLED lighting panel at the recently held Automotive Engineering Exposition (AEE) 2013 in Yokohama, Japan.

Sumitomo Chemical showed several flexible printed polymer OLED panels, these panels had been manufactured using both with a ink-jet printing and roll-to-roll (slot-die) coating technology at ordinary temperatures and pressures.

Flexible and curved OLED lighting is very attractive to designers, and offers them greater flexibility in the development of innovative and creative lighting products. Sumitomo Chemical specifically said that they expect these OLED panels to be used as ceiling and floor illumination.

In order to enter volume production Sumitomo Chemical intends to further extend the lifetimes of the emissive polymers, improve overall brightness and improve production yields.

The company expects to use both ink-jet and roll-to-roll technologies when the lamp is commercialised.

A spokesperson for Sumitomo Chemical said, "Many other companies are using small molecule. In many cases, small molecules require vacuum deposition and, thus, are not very much suited for printing. On the other hand, printing technologies can be easily applied to our polymer OLEDs."

Philips installs a large-scale OLED lighting luminaire at their US Light Application Centre
27 May 2013

Philips have recently install a large OLED lighting luminaire at their Light Application Centre in the US. The installed LivingSculpture consists of 36 separate modules, each with their own 16 OLED panels - a total of 576 individal white OLED panels.
