My mobile phone has an OLED display, It's a samsung jet. When I got it a couple of years ago I did a bit of research to learn a bit about OLED and there was a lot of hype about how OLED can produce better contrast and much richer colours. And I have found this very true especially when compared to nokias and HTC. I haven't compared it to an iphone but then samsung make the screen for the iphone and from the search I just did it looks like the iphone is probably using OLED as well so they are probably very similar.
seriously you need to do some more research....
iphone = ips led display with higher pixel density - think it's by lg... samsung do their processor/gpu and supply most of the memory/storage chips too - no oled on iphone, just 'relatively' higher pixel count
samsung = (mostly) super oled and super oled+ (basically better contrast)
htc = oled, higher quality led (pretty sure not ips)
nokia = improved oled (got a brand name I can't remember) and led
Contrast and richer colours do not make the colours accurate, they just make them pop off the screen.
Anyway, surely it is more challenging for a screen manufacturer to make a small 960*640px 326ppi display than it is to make a larger computer monitor which will only have a density of between 96 and 120ppi. And if they can afford to put OLED screens in mobile phones then what is stopping them from putting OLED in reasonably priced computer monitors? Especially if the hype about contrast and colour richness is true, which from my experience it is.
Nope, it's the other way round, led displays are basically made using one big sheet, meaning larger sheet has higher chance of faulty pixels, which means dead or rejected display.
And like I said above contrast and richness are no good without accurate colours..
OLED is still relatively expensive to manufacture and has the same issue as led when you scale up, it's also harder to manufacture than led.
