The first OLED monitor for the public was released almost 4-5 years ago, yet prices have remained stagnant for the past years. There has been no price evolution whatsoever. Every year, I consider getting one, but I change my mind when I see that prices have sometimes even increased in the meantime. It seems odd to me. I would expect an increase in production of these panels over such a period.
It is not produced by China yet. But it will be in a year or so.
