April Launch For Toshiba 100Hz LCD TVs

By Caroline Warnes | Wednesday | 28/02/2007

Toshiba will release a range of 100Hz LCD panels to complement the launch of its high-end HD DVD player, due in April.

The HD-XE1

Managing director Mark Whittard confirmed that the range will include models up to 50-inches, all of which will be capable of 1080p resolution.

A number of manufacturers showed 100Hz TVs at the CES in las Vegas in January, including Toshiba, Sharp, Sony and Samsung.

Televisions currently run at 60Hz, however 100Hz technology virtually eliminates any motion blurring seen on current models.

Industry experts speculated that vendors who came to market first with 100Hz panels would have the advantage, and it looks like Toshiba might be one vendor to secure a strong position in the LCD market in 2007.

The HD DVD player in question is the HD-XE1, which will retail for $1599. Toshiba currently has an entry-level HD DVD player on the market, the HD-E1 (RRP $1099).

Whittard points out that both players are significantly cheaper than any high-end Blu-ray players, with the high-end HD-XE1 being on a par in terms of cost with the entry-level Blu-ray player from Samsung, the BDP-1000.

The company remains confident with HD DVD technology, despite a recent onslaught by Blu-ray in the Australian market, Whittard says.

"Globally, it's roughly a fifty-fifty split in terms of players being shipped," he says. "In fact, HD DVD players are outshipping Blu-ray players, when you remove the PS3 factor.

"However Blu-ray has had more hype in Australia recently."

Would be nice if it could display at 48/72/96hz as well, but i guess its still a bit too early for those panels.

Now that's a point.

It's about time Toshiba started doing some serious promotion of HD DVD, after all it has a lot of supporters here on this forum and elsewhere and it would be nice to see they actually support us in the marketplace here in Australia.

I notice Castel is still linked to Toshiba.com.au/ as if they were still handling Toshiba products.

this is great news CM

hope the competition will bring the price of the new "100Hz" LCD tvs down....

If you were a serious TV devotee back in the day when TVs were anything but flat, you might remember a little something appearing on the poshest CRT TVs that went by the name of ‘100Hz processing’. We certainly remember it perfectly, nerds that we are, and so we’re feeling really quite nostalgic about the apparent return of 100Hz - or at least something very like it - for the flat TV world, in the shape of Toshiba’s ‘Active Vision M100’ image processing system.

If all this talk of ‘100 this’ and ‘100 that’ is causing you major brow furrowage, then allow us to explain. The idea behind the original 100Hz system was that if you use processing to double the UK’s normal 50Hz TV image refresh rate, you can remove the subtle flickering effect many people experienced with large CRT TVs - as well as, it seemed to us, making the picture look more solid and colour-rich..

With Toshiba’s M100 system the core principal is the same; scanning the picture 100 times a second rather than 50. But here, with LCD being a largely flicker-free technology, the reason for doubling the scanning rate is actually to counter the problems LCD traditionally has showing rapid motion. The thinking being that adding extra frames of picture – which is effectively what 100Hz processing does – will make motion across the screen look smoother and sharper.

The home for this M100 is the 37WLT68. And a very attractive home it is too, looking suitably high-tech in its shiny black and silver finish and slenderness-emphasising lines.

It’s a supremely well-connected TV too, giving you not one, not two, but three HDMI inputs – just the job for simultaneous connection of a PS3, Blu-ray/HD DVD deck (or both!), and Sky HD receiver. It’s great to discover, too, that these HDMIs can take premium 1080p content as well as the customary 720p and 1080i options. However, the HD support only goes so far; the screen isn’t a ‘full HD’ 1,920 x 1,080 model, instead ‘only’ carrying the normal 1,366 x 768 pixel count.

I gather the current range is 720p

BTW I remember how good the Metz 100Hz widescreen CRTs looked.

Id love to see what they look like but doesnt the 100hz CRTs relate to flicker?

LCDs dont actually flicker as such but what 100hz LCD does is reduce the motion judders or "image lag" doesnt it?

Is that how it works?

They went 100Hz on the CRT as the signal used to be interlaced, so this basically eliminates flicker from the interlaced signals.

In regards to 100Hz on LCD, I assume because movies are at 25fps in PAL, doing a mulitple of 4 will eliminate any judder that you would normallly see if that material was displayed on 60Hz. I think image lag or ghosting might be related to response times.

I thought 100hz was only relevant to analogue sets not digital[ as long it was a factor of 24fps]

cheers laurie

100hz is still nto a factor of 24hz so judder we're still stuck with ?

Umm.. I still think their market is PAL users... 50Hz television and 50Hz movies. Our movies are just sped up 4%, so as long as you're watching a PAL SD-DVD, or Aussie TV, there will be no judder. If you're watching NTSC or HD-DVD/BD, then it needs to be a factor of 24.

so with blu-ray or hd-dvd judder would still be an issue gino ?

I saw some pretty awefull judder on the iceage demo on the pana blu-ray player & 65" 1080p plasma. strangely the judder wasnt apparent on any of the other material on that demo disk.

I mainly notice "flicker" during the credits.. and I have noticed it on both LCDs and Plasma screens .. Is "judder" the proper term for this?

' Judder' is sometimes seen as jerkiness of motion when the camera pans horizontally.

'Flicker' most often results from an inadequate frame rate, thus the use in interlaced 100HZ CRT TV's to give a higher refresh rate to the phosphors on the screen. A side effect was unfortunately a slight motion blur as the phosphors were already 'pumped up' by the additional scan (over that of a 50Hz CRT).

LCD TV's are progressive by design so increasing the scan rate would only be to make them compatible with 50Hz video as it has already been mentioned.

One would think they would also be 96 Hz as well for HD DVD/Blu-ray compatibility.

You would call this judder, panning scenes and credits really show it up and jerkiness, flicker is more like a strobe light effect

Judder is an issue already for most on these HD formats unless they are watching at 24/48/72/96Hz ... I think most are watching at 50/60Hz... so they will be seeing some degree of judder. As for whether they notice or realise is a different matter.
