I doubt about that R&D being entirely spent on microLED. Small microLED lens are very difficult to produce and very costly. As optimistic as people can be, there's no microLED in VR anytime before 30s when we won't even get affordable microLED TV anytime for the next 4 years.Kalston is right, there is a big Trade off in VR when you use OLED. Brightness, motion blur, persistence, mura Manufacturers aren't pushing for MicroOled, they are spending their R&D on Micro LED. That's the future.
