Is it true that outdoor on a clear sky Oled is still readable? It is very hard to read on lcd. Maybe like what you said, led is the next smart phone screen generations?
OLED is much* better in direct sunlight in my experience. I don't know if that's due to higher brightness OLED displays I've used, the core light coming from the LED itself instead of backlight, or otherwise.

A dim OLED screen is still hard to see in direct sunlight, in similar ways to an LCD. Maybe with less ghosting.
