New 100Hz LCD TVs unveiled in Berlin
Almost every TV maker exhibiting at the IFA consumer electronics show in Berlin last week used the event to launch LCD TVs capable of a picture refresh rate of 100 images a second. You couldn’t move for bright-eyed booth staff there to demo 100Hz technology and persuade us to replace our LCD TVs already. The benefits were there to see right in front of your eyes: sharper pictures, with clearer and better-defined surfaces, and smoother movement than you get from today’s LCD screens. Current LCDs refresh the picture at a rate of 25-60Hz, depending on whether they’re aimed at the European or US markets, respectively. They essentially operate at the same rates as the HD source material: 25fps or 30fps for 720p and 1080p content, and 50 or 60 fields per second for 1080i pictures. Each field comprises only half the picture, so those 50Hz and 60Hz interlaced – hence the ‘i’ – are effectively 25 and 30 complete images per second.
Moving up to 100Hz means running the source at 100 fields per second or 50fps. Since there aren’t that many fields or frames in the source material, the TV has to invent them, using complex calculations to work out what the extra frames and fields look like. The upshot, the various vendors claimed, is an end to the ghosting effect sometimes seen in LCD TVs: that slight blurring of moving images caused because the new image is drawn even before the old one has faded away. Some TVs we saw did a better job than others, though with demo images it’s always hard to be sure the manufacturer hasn’t simply picked a sequence that shows the improvement rather better than a typical HD TV broadcast would. But hey, who watches TV in these days when we have the Internet?

“But hey, who watches TV in these days when we have the Internet?”
(on tv still some minor shows u can’t get)
truth in 90%
…who wants to watch damn commercials,
Screw LCD, bring on SED and laser projection!
LCD suxzzzz
I thought 100hz lcd’s have been around on the market for a while now…
TV is for LIVE sports.. Internet is for everything else.
100hz have been around on the market for quit a long time indeed, this is nothing new.
Uhm… i have a 1.500$ 42″ plasma. I DOUBT you can see much differens between that and a 15.000$ 100hz lcd, or whatever.
Go buy low budget, you’ll be happy you saved the money.
the only good these greater refresh rates do is give less strain on your eyes I’ve set my res to 85hz and when ever I lower it my eyes start to flicker a lit bit but still its nothing to drool over..
Three words..
LCD – Shutter – Glasses
Woo yeah they need 100Hz!
All movies are shot at 24fps, so we need more TV’s divisible to this, 72fps, 96fps etc, just wont be able to get the best picture without screen lagging and jolts with these rates
and 100hz tv’s have been around for ages, but not 100hz LCD tv’s, only CRT before this,

Sharp and sony already have 120hz tv’s geeez this is funny the new xbr4’s and 5’s are also 24p for film… and the d9 by sharp is 120hz
I wonder how overpriced those are going to be at launch ?
I smell a rip off for the first 6months – 1st year or so
You need to amend your article dude..
25 Hz for Europe and 60 Hz for the US….. you need to check your facts properly.
YOU got the story from here…..http://ohhmylord.blogspot.com/2007/09/latest-100-hz-lcd-tv-advantage.html and THEY got it wrong.
25 hz tv’s don’t exist… you can CHANGE the hz… but you can already do that type of thing on a monitor…. There are no source pictures that come in at 25hz… it’s only a frequency, which can be changed.
You should have said 50hz and 60 hz and even then there isn’t really a hard and fast rule separating Europe and US.
Sloppy.
Damn.. meant to write also that I didn’t expect this from you, you’re usually bang on.
@ 15 & 16 the name says it all really.
#17…. That all you’ve got?
