Philips Working on LCD TV Smearing & Ghosting

Philips is working on a new lamp technology to eliminate smearing. Smearing, also known as ghosting, is a problem in thin liquid crystal display (LCD) televisions because the tiny pixels that create the image take time to switch on and off.

The problem, widely recognized as the main drawback of LCD TVs, is apparent in fast moving objects such as tennis balls, but even slower moving images get fuzzy around the edges. Old-fashioned tube TV screens have no such issue, because they light up 50, 60 or 100 times per second for just a split second -- much shorter than the time to light up a flat screen pixel -- with large inactive or dark periods in between. Philips will do something similiar to a Cathode Ray Tube (CRT) by switching the fluorescent backlight on and off at a rapid pace.

I hope this works. I really hate smearing and you see it all the time on movies that are action packed.
