More Information
Summary:A plasma display comprising a noise filter circuit connected with an AC power supply, having a noise filter (253), and arranged on the back side of a plasma display panel, and a back cover (12) of magnetic metallic material arranged on the back side of the plasma display panel to cover the noise filter circuit. The line of magnetic force in the core of a magnetic body constituting the noise filter (253) has substantially the same direction as the in-plane direction of the back cover (12). According to the arrangement, the quantity of leakage flux passing through the back cover (12) can be reduced and thereby the noise can be reduced. L'invention concerne un affichage à plasma constitué d'un circuit de filtration de parasites connecté à une alimentation électrique CA, comprenant un filtre antiparasites (253), et disposé sur l'arrière d'un panneau d'affichage à plasma, et un couvercle arrière (12) en matériau métallique magnétique agencé sur l'arrière du panneau de l'affichage à plasma afin de couvrir le circuit de filtration de parasites. La ligne de force magnétique du noyau d'un corps magnétique constituant le filtre antiparasites (253) possède sensiblement la même direction que celle du plan du couvercle arrière (12). Selon cet agencement, il est possible de réduire la quantité de flux de fuite passant par le couvercle arrière (12) et ainsi les parasites.
