In September 2018 Taiwan's ITRI institute demonstrated a foldable AMOLED display prototype. The company now released this nice video showing the new display:
This AMOLED display, according to ITRI, is "rapidly approaching commercial standards". The panels are abrasion-resistant and folding resistant, and can be folded up to 200,000 times with a folding radius of 3 mm. The panels can also withstand being subjected to 1 kg of steel wool friction over 50,000 times.
There are over 500 million OLED displays produced each year (and growing), so not sure your comment about "prototype technology" is correct. There are/were also commercial OLED monitors and laptops, but for several reasons that market is not taking off. I don't think Micro-LED will enable monitors or laptop displays any time soon, the current focus is on wearables, VR and large-area TVs.
OLED is known as best technology for prototypes, but no real products in terms of monitors, laptops and other. No doubt everyone is rushing for micro LED
