I remember people were pessimistic about 4K IPS as well (inlcuding me), and IPS also initially suffered from various issues, like infamous image burn and backlight issues. And just in a few years most issues have been resolved, most kinks have been worked out, new tech emerged, and we went from $2000+ unobtainable professional monitors to sub-$350 consumer models. Two years ago I bought my sammy for just under $400. That was a case of IPS being already cheaper than equivalent TN (excluding off-brand chinese and korean stuff).
Now, regarding OLED, there are hints everywhere. Just look at latest smartphones, where AMOLED is now present not just in flagships, but pretty much everywhere across $150+ market segment (Galaxy J6 is actually under $150 nowadays), more laptops with OLED screens appear on the market every day(e.g. it finally became cost-effective for this segment), and a demand for OLED TVs and monitors is on the rise. Another big motivation for cheap OLED panels is competition, and now we know that not just Samsung and LG have the tech, but also AUO, Sharp and possibly Chimei Innolux (they had prototypes, but no confirmation on mass production yet).
It may cost you around $2500+ to get an OLED TV or monitor today, but mark my words - you'll be able to afford one no later than 2023.
EDIT: forgot one more thing, which may sound irrelevant, but is actually important to the topic of price... Some Chinese "entrepreneurs" started making counterfeit Samsung display modules that are actually real OLED, not TN or IPS. Same price as old IPS fakes, which means they already have the tech and a decent manufacturing capability, at least for small displays. Just found out about it today, when looked to restock some parts.
I bought a professional grade EIZO IPS monitor for £700 (about $1000) over 12 years ago. Maybe some were $2000+, but you could get damn good ones for far less. This isn't (and has never been) the case with OLED. There have only ever been insanely priced small sub-20" options, or big 55"+ TV's (which aren't monitors). Dell had a 30" OLED a couple of years ago, but it was discontinued because no one was interested in a 60Hz monitor for $3000 that was at risk of burn-in. And burn-in will never be fully resolved... OLED is an emissive technology and burn-in is simply inherent. I do think the problem is significantly overblown for TV use, and even gaming... unless you're playing the same game for 5+ hours a day, every day, for weeks on end. That may be a problem, but doesn't represent how the vast majority of gamers play. When it comes to general PC use though, especially people who work in front of a screen 12+ hours a day, using Photoshop, video editing, word/DTP applications etc. it IS a problem, and the risk of burn-in under these scenarios is massively increased.
Plenty of gamers would want (and could legitimately get away with using) a 27-32" OLED monitor... but they aren't going to pay the $10,000 price tag that it would most likely have. And OLED will never achieve mass market adoption beyond the gamer audience due to the burn-in risk.
As mentioned, TV's actually offer the best chance for people who want OLED for PC, with LG's cheaper 48" due next year. If that does well, they might see the market for smaller models. Yes, $2500 is what an OLED TV costs today... but it IS a TV, not a monitor, it's just that you can use it in the lounge hooked up to your PC. Smaller TV's, certainly 32", generally don't sell very well and feature lower specs. With HDMI GPUs sure to arrive next year, it's fantastic some OLEDs can now be used to their full potential for PC gaming... but no one is making smaller more practical desktop sizes, or even talking about doing so, and that's my point. We have two very divergent markets here, even though there is some crossover with PC lounge gaming.
Where in the market would you propose a sensibly priced OLED monitor sit exactly? It would involve such a major shake-up of the industry, I don't see any company standing for it given the money tied up in LCD production, sales and marketing. LCD isn't going anywhere for a long time, and we are seeing a push for further improvements on it, with FALD, Mini LED etc. and prices only increasing... $1000+ for a high end LCD is common, $2000+ for FALD options, $4,000 for professional models... ALL LCD, not an OLED in sight.
Micro LED will make an appearance at some point, which will offer all the benefits of OLED but minus its faults... although I believe this is a solid decade away at least.
Where are these cheap Chinese OLEDs and has anyone actually taken a good look at them? There have been some shocking LCD knock offs over the years, barely fit for purpose, so I wouldn't get too excited about that at this stage.
