High refresh LCDs are Ultra HD solution

Japans NHK is working on assorted research projects that will the broadcaster hopes lead to ultra high-definition (Ultra HDTV). 8000-line displays with super-tiny pixels are part of the scheme, as well as high-resolution cameras and a little help from the BBC image compression technologists. South Koreas Samsung is already preparing the groundwork. Samsung has just announced a pair of 3840 x 2160 pixel high-resolution displays (at the Los Angeles Society for Information Display 2008 event). We have already reported on the giant 82 inch device, with a double refresh rate of 120 Hz designed to give flicker-free images (pictured, left). Thats step one, and already a four-fold resolution on todays typical HD sets.

But step two takes the improved size and pixel count a stage further but doubling again the refresh rate to an impressive 240 Hz designed to exploit Blue Phase self-aligning LCDs that say Samsung - wholly eliminate any flicker, motion blur or screen blocking. These units are little more than lab demo units, and while impressive are unlikely to see a retail store much before 2010-2011, and they will not be cheap.
