There is nothing inherent in OLED having lower yields.
Two TFT layers, metal , PEDOT, oled layer ,ITO, metal
Not much different from LCD in its basic form.
I'd say that there is a potential to make them even cheaper when printed OLEDs will finally get production ready

Yes, I should have mentioned that wOLED is the way around the yield issue, but you don’t gain much. That is why srgb is what Samsung uses for small displays and which look much better than srgb (because woled is essentially lcd, just replacing white with a giant white pixel with the rest of the LCD stack the same, which can handle defects because you can hide where it is dark with the layers above)
Large format displays will be LCDs for many years due to inherent yield issues. (60” OLED displays is analogous to Intel trying to make a CPU the size of a full 300 mm wafer, one dust particle...). As the middle class grows, they will purchase large format displays.
R&D investment is Foxconn trying to move up the value chain. A dollar spent on R&D in China on innovative new ideas is less effective than that same dollar in the U.S. Especially since leading top tier LCD technology suppliers reside in the U.S./Korea/Japan.
