OLEDs and carbon nanotubes push for market growth


LONDON — The market for printed and organic lighting will exceed $2.9 billion by 2012, according to a report from NanoMarkets LC.

The report claims that the higher energy efficiencies and ability to create novel lighting products provided by organic LEDs and carbon nanotubes in particular will push the entire printed and organic lighting market up to $5.9 billion by 2014.

Most of the new business will come from the backlighting, general illumination and architectural/specialty industrial lighting applications with significant opportunities also in vehicular lighting, signage and a variety of niche markets.

Because backlighting can represent as much as 38 percent of the cost of LCD displays, there is an immediate opportunity for OLEDs, especially printed OLEDs, to reduce costs. OLED backlighting is receiving serious attention from firms such as UDC, Toyota, Tohoku Device, OLED-T and Add-Vision.

Backlighting is an area where high-brightness LEDs (HB-LEDs) have achieved significant recent penetration, but ability of OLEDs to deliver light over a wide area, make them more suitable than the point source HB-LEDs. As a result, OLED backlighting will generate revenues of $1.9 billion by 2014 according to NanoMarkets (Glen Allen, VA).

An incandescent bulb lives for 1 Khr, while OLED lights have already achieved 100 Khrs and are approaching the efficiency of fluorescent lights. OLED general illumination products have been targeted for funding by a variety of government projects in the U.S. and Europe and this segment of the OLED lighting market is expected to generate $1.4 billion by 2014. The European Commission is preparing a study on domestic lighting that could lead to the phasing out of incandescent light bulbs by 2009.

Lighting markets based on carbon nanotubes are smaller but will be worth about $520 million by 2014 and much of this lighting will be printed. CNT lighting is very rugged and cost efficient and has the potential to create such novel products as transparent signage. CNT lighting is attracting attention from major electronics firms in Japan and is also getting some funding from the U.S. Department of Energy.

Late in 2006 NanoMarkets issued a report that predicted the market for organic light emitting diodes (OLEDs), organic thin-film transistors and other organic electronics is set to be $1.4 billion in 2007 and to grow to $19.7 billion in 2012, equivalent to a compound annual growth rate of 70 percent.
