I just came off of a Elite Plasma as well. I spent a few years looking for a replacement as nothing in the LCD screen whether LED or Flouressant backlighting compares, so be prepared. I researched the OLED as I have be rolling that technology since I bought the Elite 8 Years ago. I told myself at that time, my next TV would be OLED. Sony was leading the OLED technology at that time on the consumer level. But they have failed to deliver, they had indicated that they were on the verge of releasing OLED but never did. They still leak that rumor, but it supports the acronym S.O.N.Y.-Soon Only Not Yet.
i did buy the XBR930D55 and and content with it but not thrilled. As mentioned I looked at the OLED and decided against it regardless of it's brilliance and true blacks. My personal finding was 1) the blacks lack edge detail, the processing is lacking to produce the details. Panasonic has a LG panel they are marketing with Panasonic processing and chassis and has solved this issue but expensive. 2)
i noticed some motion artifacting that could be annoying. 3) the Model I wanted was 4500 and I felt with no track record as the life expectancy of OrganicLED, I choose the Sony at 2100 (now less) and figured I would wait a few years. I think that OLED may be the future but Sony is also working on another nonLCD system known only as Crystal Vision at this time. So I will live with the Sony till then.
As far as my opinion of the Sony after 3-4 months is that it has a great picture. I still am working on dialing it in, but I am satisfied with my decision between the Samsung, LG and the Sony. The picture is, in my opinion very comparable in color reproduction to the plasma. But off axis it just dulls, and I have noticed that the edges of the picture can sometimes appear to lose contrast. But the detail is very good, bordering again with the plain of the Elite.
Hope pe this helps, and as mentioned, all my opinion based on my experiences. Others will draw their own conclusions and in the end
we all seek our own happiness.
ome last note, Philips has just announced and OLED, but I haven't investigated, as I am happy for now and my reason number 3 above still applies. Only time will provide the real life expectancy period.
