Weird article. Burn in is never mentioned. I can buy OLED displays if burn in is no longer concern for PC monitor. I wish it lasts at least 5 years without care. I'll buy even if price is high. I don't want to too much care about burn in, and throw away it every two years.
For TV, I don't replace it frequently so I hope it lasts a decade.
At least one of the recent OLED monitors (I forgot which one, maybe the LG 32") has a physical resolution of 4K plus an extra width/height of 16 (?) pixels, and uses slow pixel shift to slightly move the image around to prevent/reduce burn-in. That strikes me as a good approach.
