Saint-Gobain Display Glass offers optical front filters for
the shielding of electromagnetic interferences (EMI) and infra-red
radiations (IR) emitted by plasma display panels.
Two products are available : a coating based filter
for class A applications, Plasmashield A, and a mesh based filter
for class B applications, Plasmashield B.
Both products have been respectively FCC class A or class B qualified
with numerous PDP modules. They feature adjustable light transmissions
in the range 50-75%. The overall light reflection can be decreased below
5% thanks to the use of Anti-Reflection treatments. Our products
differentiates from competition in durability thanks to highly
resistant AR treatments and very optically-stable components
(no change in optics and IR-cutting after aging).
Plasmashield A filters are available in 4.1 or 4.5 mm thickness,
and Plasmashield B in 4.6 mm.
Available sizes range between 32 to more than
63.
APPLICATIONS
These filters are suitable for Plasma
Display Panels. They can also be used for some LCD
applications that would require specific EMI shielding.
