Panasonic showed off its new high definition plasma TV today and it is a whopping 103inches. It is claimed to be the world's largest plasma screen and has a resolution of 1080p, giving it stunning image quality.

It's way too big to fit into the homes of most people, but in the UK that won't be an option as Panasonic currently has no plans to release it anywhere but in the US. Which is a shame because from what we saw, the image quality was impressive. Hopefully you can get a sense of its size from the photo - check out the DVD players sitting underneath.

It is also releasing a 65inch 1080p plasma in the US, so in the UK we continue to miss out on such high quality TV. Hopefully this will change once high def broadcasts launch in Britain. If you want really big screens, plasma still rules, but LCDs are beginning to catch up, and this year there will be 52, 56 and 61inch models hitting the streets. Yet again though, they'll be US only.

There was a lot of jockeying for position today in the flat panel TV market, with Philips and Sony also stressing their credentials. Naturally, every company was a market leader...

Philips launched the latest generation of its ambient light TVs - Ambi Light 3 - and Sony announced seven Bravias. These are from 26 to 46inches in size.
