Fujitsu Hitachi Plasma Display (FHP) has introduced four high-definition Plasma display panels (PDP). The 32in., 37in., 42in. and 55in. models are the brightest Plasma screens currently available, according to FHP, and the 55in. model is the first WXGA unit to use Fujitsu's newly-developed e-ALIS (extended Alternate Lighting of Surfaces) technology, which features a progressive display and a brightness of 1,000cd/m2.

FHP first introduced a 42in. high-definition plasma display with ALIS technology in 1999. It then added an 32in. and 37in. model to the range in 2001. The new A1 series represents FHP's third-generation PDPs. The 42in. PDP provides a brightness of 1,100cd/m2, which is a 10 per cent increase compared to former versions. The other models, including the 55in. unit, offer a brightness of 1,000cd/m2. All four models use 10-bit signal processing and newly-developed LSI circuitry, which FHP claims offers improved picture quality.

FHP's e-ALIS technology adopts a common electrode on the front glass panel and a grid cell structure on the back glass panel. This means that only half the electrodes are required compared to other XGA panels, according to the company. This new method alternately addresses odd and even lines during addressing time, and after that, displays all lines at once (progressive display). By improving colour temperature (9,000K), e-ALIS should also allow for higher-quality colour reproduction for TV images, such as blue sky and white clouds. The new LSI should reduce noise level caused by error diffusion, making it more suitable for household use digital broadcast environments.

With the increased adoption of digital technology in household devices, exemplified by such developments as digital broadcasts and DVDs, FHP expects the market size for PDPs to increase to 1,400,000 units worldwide this year. The US is currently the largest market, with the majority of sales driven from a high demand for large TVs. FHP plans to expand its production capacity from its current 30,000 units per month to 50,000 units per month in the next month; then from 70,000 units per month in spring 2004 to 100,000 units per month in early 2005.
