The IFA 2008 show is opening officially tomorrow in Berlin. Panasonic is exhibiting five new prototype plasma display panels (PDPs) with new technologies.
The Panasonic Plasma prototypes include a 42-inch panel with double efficiency technology that halves energy consumption while maintaining the same brightness, a less than one-inch super-thin 50-inch PDP and for the first time ever a one-inch super-thin 58-inch and 65-inch PDP.
Panasonic will also be displaying the world’s largest 150-inch advanced high definition (HD) PDP.

The 150-inch PDP delivers dynamic, overwhelming image quality with an 8.84 million pixel resolution (2,160 x 4,096) - more than four times the 1080p HD specification (1,080 x 1,920). The prototype has a screen size equivalent to nine 50-inch PDPs with an effective viewing area of 11 ft (3.31 m) (W) x 6 1/4 ft (1.87 m) (H). With the enhanced PDP technologies Panasonic accumulated in the development of its 103-inch PDP, the 150-inch PDP provides stable and uniform images across the vast expanse of the screen and the same brightness as the 103-inch PDP. Featuring true-to-life color reproduction capability and quick response to moving images, the ultra-large PDP renders clear, crisp, spectacular images unrivaled by any other.
