Why Aren't OLEDs monitors a thing yet?

Ok, just some thoughts - feel free to explain to me why this hasn't been done yet.

1) Blue OLEDS dying faster than other colours - this has been solved already - just use WHITE OLEDS with a colour filter over the top. That way the RGB pixels will all die at the same rate...

2) Image burn in/Retention - OLEDs have a sub 1ms (0.01ns~) response time. Why can't we just strobe the OLEDS for 1ms every frame? Need more brightness, strobe it twice (so in a 16ms interval, strobe it at the 8ms and 16ms mark). If you strobe the OLEDs, you wont get burn in (right?)

3) Brightness - now that you're strobing, the brightness will reduce. Since OLEDs are basically transparent, why can't we stack 2 (or even more) layers of White OLEDS on top of each other? (http://www.laserfocusworld.com/articles ... etime.html)

4) Hold and sample motion blur - see 2). Everything solved.

At 1ms strobe every 8ms, OLEDS will last 8x longer - a cheap strobe controller should surely cost negligible amounts to implement? (vs the cost of researching new materials)

We know that the technology already exists (e.g. oculus rift has a rolling scan strobe), and panels can't be that expensive to make (we have 1920x1080 amoleds in our phones)

longevity is still a thing. Some people leave their screens on 24/7. An OLED wouldn't last longer than a few months under those conditions. I'm aware that the blue issue has been worked on. Still not fit for prime time, though.

Price is the main issue. They are EXPENSIVE (you and I won't be able to afford one unless you have some nice big bills to spend) and won't be in consumer price points for at least several more years. OLED monitors are currently being produced and used but mainly by the *MEDICAL* industry for use in surgery and screening (the 100% accurate colors helps immensely).

Check Andy's post. Even though what the Samsung tech said should be taken with a grain of salt.....

OLED monitors do exist, and have so for a while.

Good point spacediver, but I think XeaLouS is wondering why he doesn't have a ROG Swift OLED 1000Hz ULMB display on his desk right now (as am I). Obviously there's no consumer level OLED stuff as far as desktop monitors go at this point, and if longevity is still a big issue, then I imagine that strobing potentially 1000x/sec will kill an OLED even quicker. So even longer time to wait for low-persistence gaming OLEDs, but they must be on the horizon!

Well, the 1khz part would necessitate a very low resolution and/or compression, given the bandwidth of the connection between GPU and monitor.
And any longevity issues would be more dependent on brightness(pulse width and voltage) than on frequency.

Nah, the sony OLED monitors use rolling-scan (basically strobing parts of it at a time) so i don't think it kills it any quicker.

Well we don't need 1khz worth of frames (yet) - we can have 1khz refresh but only 200hz signal @ 1080p or so.

They are thing now!
And not just in the medical world!

Be prepared to dig deep though, they're not cheap.
