Fujitsu Hitachi Plasma Display and NEC have both unveiled prototype plasma display panels (PDPs) that push up sizes further and further. Fujitsu Hitachi Plasma Display (FHP), a joint venture formed by Fujitsu and Hitachi in April 1999 to consolidate research, development and production of PDPs, took the wraps off a prototype 37-inch screen that boasts both high brightness and high resolution. The new widescreen display has a resolution of 1,024-x-1,024 pixels, can display 16.8 million colours and has a brightness of 650 candelas per square meter. The largest screen in FHP's range of screens, which use a widescreen aspect ratio (16:9), is a 42-inch model. A recently launched 32-inch model was the second panel added. The 42-inch model has a resolution of 1,024-x-1,024 pixels, while the 32-inch model's resolution is 1,024-x-852 pixels. Both have high brightness, of 600 and 650 candelas per square meter, respectively. NEC has shown off a prototype 61-inch display, its largest yet. It was first unveiled several weeks ago at the CeBIT show in Germany, but the company provided more details about the screen at the currently-running EDEX show in Tokyo. It has a resolution of 1,365-x-768 pixels, brightness of 600 candelas per square meter and contrast ratio of 700:1. The largest PDP screen yet produced is a 63-inch model unveiled at CeBIT by Samsung.
