DisplaySearch says that the OLED industry's material growth is going to be lower than expected due to high manufacturing cost, delays in OLED TV and "very few breakthroughs in AMOLED displays". DisplaySearch now estimates the total material market in 2014 to reach $795 million (previously they estimated it to reach over $1 billion).
According to DisplaySearch, in 2014 the material market will grow 77% and in 2015 it will again grow by 70%. Growth will be much slower in 2016 and 2017. Interestingly, in 2014 the green emitter and host materials (EML) will grow by 228%. I think the reasoning is that Samsung will convert more lines to PHOLED greens (which cost more than fluorescent green). This is good news for Universal Display. In addition, it seems that blue EML costs will not grow much which probably means DisplaySearch is not seeing blue PHOLED adoption at all.
