UBI Research forecasts that the OLED lighting market will reach 82 million in 2015, and grow fast till 2020 - when it will reach $4.7 billion. As prices are expected to drop quickly when capacities expand, this means UBI sees very large OLED lighting panel shipments starting in 2016.
UBI is by far the most optimistic about OLED lighting from all market research we've seen. IDTechEx for example see a $200 million panel market in 2019 that will grow to $1.9 billion in 2025. Cintelliq sees OLED competing with LEDs in 2016, and 500 million 100x100 mm OLED lighting panels produced in 2023.
Some believe OLED lighting will never really manage to take off. IHS for example estimates the current OLED lighting market (at the panel level) at $2.7 million in 2014, and says that the market will only reach $26 million by 2020.
