436476	2006-03-07 19:24:00	Yeah, I have read about these. Something like all the good bits from crt/lcd in one? I want to get one of these to replace my crt. I have never been tempted enough to buy an lcd (althought if we rewind back a few months to just before I bought my crt, then I would buy an lcd, but it is the whole then/now thing) Come faster SED's	mejobloggs (264)
436477	2006-03-07 19:56:00	The SED could prove to be a winner, but I think it will depend on OLED (Organic Light Emitting Diode) technology as well. If OLED becomes too much of a hassle, SED just may succeed	Myth (110)
436478	2006-03-07 20:42:00	If I remember correctly, one of the problems with OLED is that the pc size screens had a life time of something like 1000 hours. But maybe they have fixed that since I last read that (was last year or something, a while ago)	mejobloggs (264)
436479	2006-03-07 23:16:00	There was an article in the latest PC Authority on pages 18-19 (yes I do read other mags as well as PC World :p). It did say there were still quite a few issues with the technology, but to start looking for screens to appear at/by the end of the decade.	Myth (110)
436480	2006-03-08 00:27:00	No!!! I want it yesterday!	mejobloggs (264)
436481	2006-03-08 00:55:00	Toshiba have them now although they are $10,000US. They aim to have 40% market share by 2007. So....say 2010 for us poor people?	pctek (84)
436482	2006-03-08 01:35:00	If it turns out to be as good as they say it is it should force the prices of plasma and lcd screens down to where the average person will be able to afford one and crt's will probably go away finally.	CYaBro (73)
436483	2006-03-08 02:03:00	Like all new technology it's perfect.:D And very expensive. Like all new technology it will be much better when the bugs are out (if ever) and when the manufacturers discover how to make it. Josephson Junction technology was going to be the miracle successor to silicon technnology for computers. CRTs have been in mass production for over 50 years. They know how to make them.	Graham L (2)

"People don't really know that from a technical standpoint, it is the grey-scale reproduction of a TV that determines how well it reproduces colour." Now that is a mouthful of misinformation. Purity of black?? I don't think so. No visual display system (other than printing I guess) can "produce" black, in reality all you see is the "power off" colour contrasted to the lighted pixels around the "black" area. The "off" colour of a CRT varies from dark grey/green to a fairly solid and very dark grey. The same applies to LCD screens, plasma screens, and even the good-old white screen used for projection technology (not projection TVs, they are still good-old CRTs). Whatever technology you use, there ain't no black!! He is partially correct about the importance of greyscale, but that only applies to CRTs where the "black level" has to be set individually for each gun and an imbalance will produce incorrect colours. It doesn't apply to projection technology or LCD/Plasma, or this new technology. As for contrast ratios, they depend entirely on how bright you can drive the pixels, because the "black" reference is simply zero light emission from variously coloured backgrounds. Black on a movie screen is produced by killing the house lights and using sufficient lumens to fool your eyes into thinking the unlit areas on the white(ish) screen are actually black. You can achieve any contrast ratio you like, provided you are able to pour enough lumens onto or out of the screen, and the viewers are prepared to wear dark glasses to watch! Hype aside, the technology sounds interesting. Cheers Billy 8-{) :rolleyes:	Billy T (70)
