Panasonic is developing a plasma set it will claim as the world's largest TV barring a surprise from rivals, says a claim in Japan's Daily Yomiuri. The paper points to anonymous sources which say the set will measure 150 inches diagonally, beating out screens such as JVC's 110-inch rear projector for the title of the largest home TV regardless of class. The size of the screen alone will be large enough to stand taller than an adult, the newspaper claims.

Other specifications are unknown for the set, though it should reach a minimum 1080p resolution and may represent the grafting together of four smaller sets to reach its anticipated dimensions. The story claims a public debut at the Consumer Electronics Show in Las Vegas next month but hints that production models are unlikely to reach buyers until 2009. Panasonic recently offered a 103-inch plasma set but has since discontinued it, though whether scarcity of parts or low demand resulted in the change is unclear.
