Who knows what OLEDs may bring in! Also, until we have a stable blue light source for organics, it is all talks. What we do know is, these potentially consume lesser energy, are aesthetically pleasing and have wider application areas. Do not forget the flexible wristbands or the curved displays in premium smartphones.
With research into TADF materials, we could potentially have a much cheaper lighting solution. Unless we have a stable blue light source, we will end up paying heavily for the touch bar in MacBook Pro 2016. I wonder if the OLED devices would be reasonably priced, once we have the appropriate solutions. Probably not, that could be just wishful thinking.
