My big takeaway from The Display Summit is the progress being made in Micro-LED (inorganic LEDs). There was a particularly interesting presentation by Yole. Micro-LED could be a serious threat to OLED in a lot of different areas, big and small. There was a lot of information on (true) Light Field displays, I was a big surprise how much work was going on but it is still a very high end and specialized solution, not something for mass production anytime soon.
I have a big project I am working on right now that is going to take a lot of my time. I will see it I can squeeze out a summary.
