A modular Anti-EMI structure of PDP device

A modular Anti-EMI (Anti Electric Magnetic Interference) structure which can be assembled with a front cover set to form a PDP (Plasma Display Panel) device. The modular Anti-EMI structure comprises a rear cover, an optic filter, a first positioning plate, a PDP, a second positioning plate and a third positioning plate. The second and third positioning plates are made of metal. The PDP is fixed to the first positioning plate. One end of the second positioning plate is fixed to the rear cover, another end thereof is fixed to the third positioning plate in such a manner that the optic filter is clamped and fixed between the second and third positioning plates. One surface of the optic filter is formed with a conductive film. By means of the structure of the third positioning plate, not only the conductive sponge needed in the prior art technique can be omitted, but also the difficulty in designing the relative locations and structures of the above mentioned elements is decreased.
