According to the Korea Herald, Samsung Electronics demonstrated several new display technologies in a private room during the Mobile World Congress last month. All of these technologies are expected to enter production within the next year or two, according to the source quoted by the report.
1,200 PPI AMOLED for VR
The report claims that Samsung demonstrated a high-resolution AMOLED panel for VR applications. The AMOLED on display featured a 1,200 PPI - much higher than Samsung's current highest density displays which are 577 PPI. Samsung's aim is to reach 1,500 PPI which will greatly enhance the VR experience.
In November 2016 Sunic Systems announced that it developed an plane-source evaporation-FMM based AMOLED production process that can reach very high densities. The 100um mask announced in November can achieve a PPI of 1,500. This may be the system that Samsung is now testing. Sunic says that eventually this technology will enable even 2,250 PPI.

Can you quote a study or something? Because the claims about PWM causing all sorts of health issues sound fishy to me considering that people used CRTs at 60Hz for many years basically just fine.
PWM is a way to control brightness, not to prevent burn-in.
CRT displays had luminophor that continued emitting light for some time after it’s formally off, so flickering was somewhat smoothed. With OLED, we have hard on/off with almost no afterglow.
I have sensitive eyes and after looking at my samsung galaxy s7 for half an hour my eyes start paining me, while I can look at my LG OLED tv all day long without any issues.
It's for both
How exactly could PWM prevent burn-in?
Samsung uses PWM technology in its OLEDs to prevent burn-in, but it causes eye pain, Does any of these new technologies will make it possible for samsung to get rid of PWM?
And what technology does LG uses to prevent burn-in?
