Panny Gets the Lead Out
Posted 29 November 2006 - 08:53 AM
Panasonic said its self-branded Plasma TVs are the first in the U.S. market to feature lead-
free plasma display panels, a move that's being viewed as an environmentally-friendly way
of producing next-generation television sets.
The display panel is the Plasma TV's glass-sealed image display device, equivalent to a
cathode ray tube in a conventional television. In addition to the elimination of lead in the
panel, Panasonic has also made advances in enhancing the performance of the phosphors
used to render colors on the screen.
In conventional manufacturing processes for plasma display panels, lead oxide glass is used
in the dielectric layer, electrodes, glass sealant and other structural elements. Lead oxide
glass was valued for its ability to stabilize production yields and quality. Today, however,
stable production yields can be secured without the use of lead oxide, Panasonic said.
The effort has allowed the company to eliminate all of the roughly 70 grams of lead used in
a 37-inch plasma panel.
