Stealing LG and Samsung's thunder at the 2006 consumer electronics show (CES) in Las Vegas (the two Korean manufacturers had previewed 102in panels), Panasonic introduced their 103in TH-103PF9 plasma which held the title of worlds biggest flat screen for a year.
Sharp introduced a 208in LCD at the 2007 CES, and this coming year, Panasonic is set to regain its crown at the 2008 CES with a leviathan 150in Plasma. Panasonic have not released any details of the new screen simply saying that it was; "putting its efforts into developing larger screens" because the 103-inch was well received.
Available in the UK for around £56,000, Panasonic's 103in TH103PF9 Plasma has not exactly hit the best selling list, but it has shown that there is a market for screens on this scale. If the 150in screens does make it to the UK, it may actually retail for a lot less than you may imagine.
It is likely that the 150in screen would be an early prototype from the Panasonic's state-of-the-art PDP production line in Amagasaki, western Japan. Operating with larger 'Mother Glass' the new production line is more advanced than Panasonic's current production facilities, and has the potential for significant cost savings and improved quality.
Whether or not Panasonic's leviathan 150in plasma actually breaks cover at CES 2008 is not certain, but what we can be sure of is that manufacturers will be striving for the 'worlds largest' crown for some time yet.
