OLED Displays Technology Primer and Forecasting
HawKe writes "OLEDs are back in the news and Audioholics reports on what makes the technology so special as well as who leads the pack in currently shipping products, vaporware, and displays that are on the horizon. The crux of the matter is whether or not OLEDs, the "eco-friendly" choice, can outpace current LCD and plasma display advances. In order to enter and dominate the home theater and computer display markets, they must not only establish themselves, but also beat the leaders in price and performance."
Finally a new type of display to use. Normal CRT monitors and TVs screen burn, while being really bulky, lcds have shadow effects and can be damaged REALLY easily sometimes, and plasma displays screen burn easiest. I wonder how this will compare to the rest of the other displays we, as consumers, have used for quite some time!
If so, what is the MTBF (mean time before failure, right term here?)
or what is the lifetime of such a LED device?
Imagine your display goes fuzzy and blurred in the middle of a good film.
Hey, that's my password you are typing
My big gripe with standard LCD displays is the complete inability to truly display black. This leads to a pretty crummy contrast ratio relative to conventional displays and good plasma displas. LCDs are getting better, but OLED might just be what we need. The article desribes it as self-illimunating, though, so I don't see why it can't display true-black, since there's no backlight, but for a technical article, it sure is weak on the details.
How often does your company buy new printer paper? Do you use fountain pens and ink wells, or cheap ballpoint pens that you throw out every three months?
If OLED displays really will be so much cheaper, maybe it's time to start thinking of displays as a disposable resource.
5h a day, 200 days in a year, that's 2 years.
Are there actually jobs like this? If so, where do I sign up?
Actually, he's right. If you actually bothered to do research on the process, you'd know that the article is wrong. It's not like it's the first time that the /. editors have posted something without doing fact checking.
I'm probably at the karma cap. Mod up a funny troll instead, it lightens the mood
OLEDs die.
I was under the assumption that this was the main reason holding OLED displays back. Now it would seem that the panel described here is only for lighting purposes (white light only, no colors or even pixels for that matter), but presumably it will still die or at least dim after a few thousand hours of use.
I recognize that this is not a major problem with cell phone displays and such, but if you plan on building the lighting of your house with these, you won't be too happy if next year or the year after that you get only 300 lumens instead of the promised 1200.
I am glad that OLED's are making their way into the market now, but, as my stance is with all technology, I will wait until it matures to be cheaper, last longer, and overall, be better. Remember Wi-Fi when it first came out? Ugh, dreadful. But now, it's a very mature technology that performs great for most people's needs. I have the same opinion on what will happen to OLED's. This has great potential, it just won't be seeing any of my hard-earned dollars until it proves its worth. ~1000 hours isn't worth it to me as of yet.
And how long do you think it will take them to jack the price of the "refills" sky-high...
You know, like printer ink and razor blade cartridges?
Lets not give the megacorps yet another "disposable" item they can soak us for... besides, wouldn't it suck if your monitor suddenly "died" at 7pm on a Saturday night or something. Good luck finding a "refill" for it.
I've got to wonder if that's a typo. The last time I read something about OLED lifetime it was lamenting that blue only had a 10,000 hour half-life as opposed to 20,000 hours for red -- and that claim was probably from a pdf found on some university's faculty home pages.
D'oh, I forgot to be more specific, the fade isn't lag time, but rather, as the screens age, some colors will go dimmer faster than others, changing the overall "color tone" of the screen. I see no point in buying an OLED screen when only one good color is still useful. Now, using the "white" compound with color filters in front of them might have to suffice, provided the color of white is stable.
I haven't seen any word on whether the primary colors can be truly SMPTE compatible. If it isn't, then it would be much harder to calibrate the screen to make it look the way it should.
OLED panels don't just suddenly "die" (unless an electronics defect occurs). They'll probably get gradually darker, and the color balance will start to be off.
You'll have plenty of warning before having to buy a "refill".
I like the idea, but you may be right about the price thing.
Don't whistle while you're pissing.
