N-Tech Research (Nanomarkets) released a new OLED lighting report (OLED Lighting 2015-2022). The company acknowledges that OLED lighting still lacks the momentum they expected by now, by they still see the OLED lighting market reaching $1 billion in sales by 2020 and over $2.2 billion by the end of 2022.
N-Tech says that we've seen impressive gains with OLED performance, and they expect to see increased emphasis on efficacy now. But of course the biggest issue with OLED lighting is the cost, and suppliers remain cautious and so the capacity expansion that is needed to lower costs are not here yet.
