Yes, the inkjet OLED has also been around for quite a few years and still hasn't made it to market either. It is a nice idea that isn't entirely ready or companies would be doing it. For OLED, unless they have solved the issue, OLEDs were known to dim over time, not unlike a Plasma. I know they have minimized some issues with Plasmas in the last few years, and Plasma still isn't a growing market. So until they make it competetive with LCD/LED on a cost basis, it isn't really a factor. Sure they can put it into production, but if they can't sell it at a price comparable to other displays of the same size, they just aren't going to sell that many, at least not right away. LCD and Plasma were in the same boat at one point, but now they are less expensive and the performance is there, so only time will tell if OLED will be able to do the same.
CRT is still the best display method for the blackest blacks and excellent brightness and you don't see those around anymore do you? So being the best isn't always what sells. People want thin. My new TV is a 55" and it weighs less than the 40" it replaced and is about 1/3 as thick. That happened in just 2 years time.
LG is touting 100,000 hours lifetime on all colors, which, as I understand it, is equivalent to current plasma and LCD lifetimes. (I previously posted this link to this thread.
) There's a lot more info at that link on, say, greater than 100 % NTSC color gamut, contrast ratios - in what is likely a "real" contrast ratio than a bunk one, etc. I hope you enjoy browsing it.
Actually, I do see CRTs still because I still have one as my main HT display.
Yet, I think my wait to retire the 'ole tube will be well worth it.
Did I mention also that Samsung is hinting that they, too, will have a 55" OLED TV at CES?
Yes, you are absolutely correct. None of us can go to our favorite HT store, where ever that may be, and buy an OLED TV today; however, the ability to do that act appears imminent. As I see it, because no one is selling them yet does not mean that some manufacturer somewhere has not employed the technology to make them, printed or otherwise. If an announcement of their impending sale is made at CES, IMHO, that, by extension, means they have at least come very close to solving the "problems" OLED is claimed to still have.
When OLEDs show up for sale somewhere will be the point in time whereby it is determined whether they have solved the cited problems. OLED R&D has been going on behind the scenes in full force. AFAIK, the problems cited are said to have been solved.
