Samsung showcased 31" OLED prototype at the CeBIT in Hanover. These are expected to be in mass production by some time next year, possibly available for purchase in early 2010. Samsung didn't release the specs on this prototype; but displays are expected to have a contrast ratio of up to a million to one! (Super dark blacks and super bright whites.) And response times of less than a tenth of a millisecond. They are much thinner than LCD's (and use less energy) because they don't need a backlight (since they emit their own light). They also had an 82" 2160p LCD display there. (The largest single LCD display in the world, which can already be purchased.) http://www.tomshardware.com/2008/03/...oled_displays/
I am sure these will be out of my price range initially. But it is something to look forward to eventually.
