large plasma display panel products for viewing high-definition television
broadcasts at Electronics
Show '98 in Osaka.
|NEC Corp., Pioneer Electronic Corp. and Matsushita Electric Industrial
Co., Ltd. all debuted 50-in. panels, while Sanyo Electric Co., Ltd.
exhibited a 42-in. model. and Hitachi Ltd. is showing two different
panels measuring 42-in. and 41-in.
Hitachi's 42-in. PDP was manufactured by Fujitsu Ltd. Although Sanyo
is not publicly saying so, it appears that Fujitsu also made the Sanyo
panel being exhibited.
The NEC panel on display at the show comprises 1,365 x 768 pixels and
its luminance is 250 cd/m2, which means that it is a full
50 cd/m2 brighter than the 200 cd/m2 panel the
company was exhibiting last year.
NEC said this improvement was achieved by increasing the efficiency of
the fluorescent matter used and by modifying the barrier ribs structure.
In dim light, the panel has a contrast ratio of 350 to 1. NEC has plans
to turn it into a product ready for release some time in the fall of
Pioneer's PDP has 1,280 x 768 pixels, its screen luminance is 180 cd/m2
and its contrast ratio is 250 to 1 in low light conditions. Its power
consumption is less than 500 W. The company said it is scheduled to
go on sale some time in 1999.
The Matsushita PDP being exhibited at the show has 1,125 x 650 pixels.
According to a source at Matsushita, the company would like to increase
the number of pixels to 1,280 x 768 before releasing it as a product,
although target dates for a product launch are yet to be decided. The
luminance of the panel's screen is 200 cd/m2 and its contrast
ratio is 70 to 1 in bright light and 300 to 1 in dim light. Its power
