Fujitsu Hitachi Plasma Display Limited (FHP) has announced the development of its new 55-inch full spec high definition plasma display panel (PDP). It realizes finely detailed and magnificent expression with twice pixels (2mega-pixels : horizontal 1920 x vertical 1080) compared with conventional XGA panel. It boasts high brightness of 1000cd/m2, high contrast of 5000:1, employing newly developed grid cell structure, electrode structure, discharge gas mixture, high speed driving and high contrast processing (full-black driving method). This product will be launched in summer 2006.
Unlike LCDs or projection-type displays, PDPs are self-emissive devices that have won wide acclaim for their superior ability to reproduce the subtlety and emotional depth of original video imagery, and wide viewing angle. Incorporating technologies to increase brightness and improve image quality, the new 55 inch full spec HD PDP beautifully reproduces images where impressive display performance and feeling of presence are paramount, such as subtlety gradation in movies, cottony clouds or snowfield in natural scenery.
The United States and Japan already have systems in place to handle high-definition programs, while China and countries in Europe are planning to introduce their own high-definition broadcasts. Therefore, the infrastructure enabling people worldwide to enjoy top-quality high-definition images is expanding, which will give rise to calls for further progress in image quality and screen size. Full spec HD PDP makes it possible to realize the original images from high definition broadcast without any conversion. Since 55 inch full spec HD PDP is advanced display device that meets those needs, we believe it will continue to rapidly proliferate.
55inch full spec HD PDP was unveiled at HITACHI booth in CEATEC Japan 2005 in early October 2005.
Main Features of 55-inch full spec HD PDP
High definition of 2.07mega-pixels (horizontal 1920 x vertical 1080)
In general, high-resolution panel brings some demerits, such as lower brightness and luminous efficiency. FHP resolves those demerits by newly developed high density grid cell structure(0.21 x 0.63mm2 per each cell), electrode structure and discharge gas mixture. Moreover, by establishing stable process technology for fine cell forming, FHP achieved 2.07 mega-pixels with high brightness and contrast.
Brightness 1000cd/ m2 (peak), Dark-room contrast of 5000:1
Adopting high speed driving method (1.3 times faster than the previous model), this PDP realizes high brightness of 1000cd/ m2 (peak) in spite of high resolution. (2.07 mega-pixels)
Full-black driving method for lowering background brightness results in a dramatic improvement in dark-room contrast of 5000:1.
Enhanced-quality picture control for various images
By progressing our original algorithm for various signals processing, this PDP enhances an optimal matching of motion/motionless pictures, and obtains high expressiveness of gradation and excellent image quality for motion picture. This brings beautiful reproduction of dark images requiring a delicate touch, such as in movies.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
