Lighting manufacturer Verbatim is planning to showcase a new range of OLED light panels produced using a wet coating method at the beginning of April. The panels will be unveiled at the lighting industry event Light + Building 2014, held in Frankfurt from 30 March to 4 April.
The lights are an extension of Verbatim's existing Velve OLED range and will complement the company's existing conventional LED products. The new panels use a white (W)OLED technology and are produced using the wet coating process which Verbatim has jointly developed with its parent company, Mitsubishi Chemical, and Pioneer.
Costs cut?
The new production technique is offering a reliable method to make large, high-quality WOLED panels. For the new Velve panels, the wet coating process is only used on the base layer, while the emissive and top layers are deposited via vacuum thermal evaporation.

In 2013, the companies claimed that the process could cut production costs by 90%, removing a key business barrier to the roll out of high performance, long lifetime, low energy consumption OLED lighting products. The colour-tuneable Velve OLED panels have received a positive reception since evaluation models were first unveiled in 2011.
A year later a development kit to demonstrate the potential design options OLED lighting can create; these came with a price tag of $800 (€578).
A roadmap developed by Mitsubishi Chemical calls for the development toward commercialisation for the rest of 2014, resulting in sales revenue of ¥3 billion (€20 million) from the new panels in 2015.
Modular and beyond
Philips has also invested heavily in OLED lighting including development packages under its Lumiblade brand. It too will be displaying new products at Light + Building 2014. These include a new modular OLED lighting system designed for installation in commercial and office environments. The Philips lights will have a lifetime of 50,000 hours and give a brightness of 500 lumens from each four-panel module.

The company has also announced that Lumiblade technology is being sent into space. It will be installed on the payload of the Flacon9 rocket, a commercial space venture, due to launch in late March 2014, carrying a cargo package to the International Space Station.
Screen production
The impulse to cut the costs of WOLED lighting may also benefit from advances in the consumer goods market. Research published in February has indicated that WOLED screens, like those now made by LG, will dominate sales in the second half of this decade; creating potential synergies in production for light manufacturers.
