Abstract

Disclosed is a method for making a film assembly used in a PDP filter positioned on the front surface of a PDP, a film assembly manufactured by the method, and a PDP filter using the film assembly. The method includes the steps of providing a roll of an EMI film having a number of conductive effective screen portions formed on a surface of a long transparent polymer resin film with a predetermined spacing and mounting the wound roll of the EMI film on a first feed roller; providing a roll of at least one long transparent functional film capable of covering at least partially the effective screen portions of the EMI film and mounting the wound roll of the functional film on a second feed roller which is spaced a predetermined distance from the first feed roller; and positioning first and second compression rollers with a predetermined distance from the first and second feed rollers while facing each other closely and feeding the EMI film from the first feed roller and the functional film from the second feed roller into a gap between the first and second compression rollers so that the EMI film and the functional film are integrated with each other and form a film assembly.

Description

technical field [0001] The present invention relates to a method for preparing a film module for a PDP filter located on the front surface of a plasma display panel (hereinafter referred to as PDP), a film module prepared by the method, and a PDP filter having the same , more particularly, the present invention relates to the preparation method of the film module that is used for PDP optical filter, this method can mass-produce the EMI film comprising the conductive effective screen part that is formed on the transparent polymer resin film, and roll-to-roll (roll-to-roll) mode is attached to the film assembly of the functional film of the effective screen part of the EMI film, and the present invention also relates to the film assembly prepared by the method and the PDP optical filter with the film assembly. Background technique [0002] In general, a PDP is an image display device that displays images using plasma generated by gas discharge. The PDP can be manufactured to ...
