Super broadband wave absorption film (Transparent film)

Configulation of a plasma display and a liquid crystal display, countermeasuring points are shown below (a picture : Configuration of display and countermeasuring points of leakage of electric wave).
Usually, iron or aluminium, plastic with aluminum evaporation are used for cases.
On this occasion, as countermeasures, holes of the case is blocked by conductive sheet, the case is mounted through conductive gaskets and the case is floating in the air electrically so that it won't become an antenna.
But thesedays, it is a big problem that inside of a case may become a resontor and unnecessary electromagnetic wave is amplified a hundredfold and even 500 times, then some amount of wave leak from holes of a case or cables, display. To improve such problem, this super broadband wave absorption film is effective.
