why there are no AMOLED/OLED desktop screens?

In 2006 samsung had 17" 1600x1200 desktop AMOLED prototype

Yet its 2014 and there are actualy no progress, actualy compared to ccfl color gamut, wled is degradation ( most modern screen backlit are far below of what i consider acceptable )

I'd personaly would be much better off with some kind 17" oled that has perfect blacks and contrast and overall quality, then 30" with terrible backlit

Japan and south Korea are the countries that are receiving these new technologies first (It's still damn new tech even for them). They are always light years ahead of the world and so instantly there is a market for these Oleds.

As such, I think they are being demonstrated/promoted to show there full capabilities, TV/Home movie screens seem the perfect example.

I remember the talk of OLED being the business and then I heard they were having major problems with the life span and that was the last i heard. I would sure like to see this tech on the market.
 
Those rumours are true but apparently it takes ages for the colours to fade. Sony and Samsung are convinced consumer will have many years of usage before fading starts.

This is from wikipedia:

Lifespan: The biggest technical problem for OLEDs was the limited lifetime of the organic materials.[55] In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at 8 hours a day) when used for flat-panel displays. This is lower than the typical lifetime of LCD, LED or PDP technology—each currently rated for about 60,000 hours to half brightness, depending on manufacturer and model. However, some manufacturers displays aim to increase the lifespan of OLED displays, pushing their expected life past that of LCD displays by improving light outcoupling, thus achieving the same brightness at a lower drive current.[56][57] In 2007, experimental OLEDs were created which can sustain 400 cd/m2 of luminance for over 198,000 hours for green OLEDs and 62,000 hours for blue OLEDs

I'm guessing 4 years of perfect Image. IMO I think this new technology is best suited to Mobile phones and tablets.
 
My galaxy note 2 wasnt even 18 months old before the screen was noticeably dimmer (colour temp had gone well down the kelvin chart to a yellowy tint) and has screen burn from the browser icons. I couldn't own a monitor that would degrade that quickly.
 
I think I read somewhere that the biggest problem with OLED is the manufacturing yeild rates. So when you see these perfect panels at trade shows there were probably 4 or 5 that went in the bin because they had defects (should have sent them to korea ;)).

I guess with phones they can negate this by selling more of them, but TVs and monitors aren't sold in high enough volumes.

This is a bit of a naive question but how on Earth do they know it takes say, 14,000 or 60,000 hours to half brightness? Surely they don't test them for that long.
I guess they must have some function of decline which can be modelled in silico.
 
Some manufacturers cited problems with production, resulting in a low yield and high cost.
Another problem appears to be burn in of images, like the old plasmas.
 
It feels like I've been waiting ages for the chance to buy an oled monitor.

The main "issues" with oled are well known, from manufacturing issues, to longevity, screen burn etc.

However there are good signs, aside from Lg and Samsung, AUO have started production of oled panels, granted they're small panels at the moment (used in phones, watches etc) and JOLED (a new japanese amoled company) are starting production from January 2015 and they are making mid sized displays.

If I was to bet on it I'd say we'll see a pc monitor with an oled panel that is actually sold at retail in the UK in 2016.

It's frustrating as I'd love one now. I'd gladly pay 800 quid for even a 24" with a 1080p panel. I'd much rather the stunning contrast oled screens produce than a high resolution ips panel with backlight bleed, grey blacks and ips glow.

OLED has only really started to be taken seriously in the TV market now, however, still with lots of problems, burn in being the main thing, uniformity issues, dead pixels etc. I say in 2-3 years we should start seeing a lot more OLED TV's on the market. Unfortunately I think it will be at least 5 years for cost affordable OLED monitors. Only way I would consider OLED for my monitor is if they can somehow avoid burn in, it happens pretty easily on the TV's atm so imagine what it would be like for desktop and gaming usage....

Until then, VA panel is the only decent choice if you want better blacks.
