This work was enabled by its work with Conductive Inkjet Technology and their joint 'NOMAD' project funded by the Government-backed Technology Strategy Board. \nProject NOMAD started in 2007 with the aim of developing technology for the next generation of low-cost OLED devices by combining advanced manufacturing methods with state-of-the-art polymer OLED materials (P-OLEDs) to enable significant reductions in manufacturing costs for devices such as P-OLED lighting panels. \nThis demonstration has shown the potential for patterned metal tracking using electroless metal deposition as a replacement for both Indium Tin Oxide (ITO) and traditional sputtered tracking. ITO is widely used as a transparent conductor in the displays, lighting and photovoltaics industries, but is in short supply and expensive. \nMoreover, ITO is very brittle and can crack during processing, limiting its attractiveness for the next generation of flexible electronic devices. ITO has a high resistivity, this creates problems for large area lighting panels due to the large voltage drops encountered towards the centre of the device giving rise to an unacceptable drop-off in light intensity \nThe manufacturing method demonstrated in the NOMAD project reduces costs by eliminating ITO along with significantly reducing the capital and processing costs for patterning metal bus bars which distribute current and ensure the uniformity of light emission. CIT's (www.conductiveinkjet.com) process eliminates the need for traditional vacuum sputtering equipment and etching tanks. \nCIT's photoimageable materials have been used to produce sub 10micron copp...
