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.
