In its new report “OLED for Lighting”, Yole Développement presents all OLED Lighting applications and associated market metrics for the period 2012-2020. As the market research firm puts it, the OLED industry is just entering the lighting market, and on this new battleground, OLED will have to compete with LED technology which has already paved the way with a revolution in Solid State Lighting (SSL). The high cost of OLED technology will not make mass market penetration easier and current low efficacy could slow its adoption. OLEDs will develop slowly in the lighting market and attract mainly niche applications, differentiating through design possibilities. To access traditional market segments such as commercial lighting or office lighting, OLED technology will have to find a spark, as well as combine enough different niche markets to achieve the economies of scale that will decrease costs. In Yole Développement estimation, this should be triggered by 2014 with the use of larger substrates and better process control.
“OLED lighting panels will reach a market size of nearly $2.8M in 2012 and will peak to nearly $1.7B by 2020”, estimates Pars Mukish, Technology & Market Analyst, LED & OLED at Yole Développement. Growth will be driven mainly by general lighting applications, representing more than 70% of the overall OLED Lighting Business in 2020.
Which technology approaches can drive OLED into mass production?
As for any emerging technology, a large variety of materials and OLED structures are used in production or tested. Moreover, alternatives to existing materials are still actively researched in order to improve the light performance, lifetime, and decrease manufacturing costs. Although the uncertainty about the future winning material approach between small-molecule OLED materials and polymer materials remains, polymers continue to struggle to demonstrate the ability to turn their cost and performance potential into an industrial reality.
Rigid glass maintains its exclusivity as a substrate material in OLED lighting panel production. However, progress has been made
