Shots fired in NEC Fujitsu PDP battle
avid Manners NEC and Fujitsu are locked in a battle for supremacy in plasma display panels (PDPs). The campaign is being fought on three fronts: in the law courts, in superior technology and in manufacturing prowess. NEC appears to have won the legal battle following a Fujitsu court action alleging that NEC’s technology was not proprietary. According to Sumito Seko, general manager of NEC’s colour PDP division, NEC has now established in the courts its rights to the technology it is using. The company also claims a superior manufacturing process. “Only NEC has a production line capable of making two panels (42in. on the diagonal) from one glass substrate,” said Seko. “That will give Fujitsu problems when it comes to competitive production costs.” An advantage in brightness with its latest 400 candela/m2 panels is another NEC claim. Seko said that this derives from the ability to encapsulate the filters within the glass substrate which only NEC can do. At the moment NEC’s disadvantage is that it started production some time after Fujitsu and is now running 5,000 panels a month with a 70 per cent yield to achieve 3,500 working displays a month. NEC plans to increase production sixfold over the next four years.
