3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
An electromagnetic wave shielding film electromagneticinterferenceshieldingfilm
Plastic film (e.g., polyethylene terephthalate PET) surface of the plated transparent metal layer or a metal mesh, an electromagnetic wave having a barrier
Radiation function of the functional film.
3.2
Optical filter opticalfilter
An electromagnetic wave shielding film and a film having other functions (e.g., near infrared resistance, hue correction neon discharge, and reduce the surface reflection) in a combination of
Since mounted directly on the plasma TV, or the like attached to the flat glass after the installation of special filters used on the plasma TV.
3.3
Shielding effectiveness shieldingeffectiveness
SE
In the same excitation level, the non-shielding materials and shielding material when received specific power or voltage, and logarithmic. which is
SE = 20lg (V0/V1) (1)
Or SE = 10lg (P0/P1) (2)
Where.
SE --- shielding effectiveness, in decibels (dB);
V0 --- without shielding material received voltage;
V1 --- when shielding material received voltage;
P0 --- without shielding material received power;
P1 --- when shielding material received power.
