I'm just about literally waiting on the edge of my proverbial seat for this technology, but unfortunately there are some strategic hurdles that are hindering its widespread adoption. From what I've read, the major display manufacturers fully intend on adopting OLED technology as it is superior to LCD's and even plasma in just about every way. Better contrast rations, more responsive, more efficient, better inherent color gamut, hell, the stuff can in theory be used as wallpaper or even a billboard. Most importantly, it's actually CHEAPER than LCD's are to manufacture. Or at least they will be, once the factories are converted over at great cost to produce OLED displays. That's the kicker. For the time being, even though LCD's are more expensive to manufacture since they require several major components (glass, several layers of crystal, fluorescent tubes, etc.) the manufacturing conversion to produce LCD's has already occurred so now they must fully recoup their investment in these facilities and allow the technology to mature more fully before they're willing to incur the expense of yet another facility conversion.
As for the manufacturing difficulties OLED's face, those have largely been eliminated. The biggest issue OLED manufacturing faced was the rigor with which facility sterility was ensured in order to prevent the carbon-based displays from being contaminated with foreign "stuff" that would literally cause the displays to "rot". A "clean" environment" is an expensive environment, therefore OLED's were an expensive technology to produce. Fortunately, a couple of years back a technique was devised that involved using a protective spray-on sealant that was applied to the displays directly after the manufacturing process largely eliminating the single biggest issue (rot) with OLED adoption.
Although the technology has now improved to be considered not only feasible, but inevitable by some accounts, it is not without it's issues. The life span of OLED based displays is still relatively short at 7 years (last I'd read), but that is not necessarily a bad thing for consumers and DEFINATELY not a bad thing for manufacturers. If everyone adopts this technology (which I hope they/we do) then periodically consumers will have to ?refresh? their purchase, thereby sustaining the profitability of the market indefinitely. With consumers purchasing displays at periodic intervals, hopefully that will translate into a continuous reduction in cost since so many panels will be purchased throughout the lifespan of OLED technology.
To me, seven years is not that bad for having to repurchase a display since most of us have probably purchased several iterations of displays within the last seven years anyways. So, at worst, arguing against OLED?s due to limited their limited life-cycles is a moot point and, at best, it?s a good thing for both the industry and the consumer.
Anyhow, long story short, the technology is awesome; it?s just waiting for the LCD market to fully mature and retire.
