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 providing a roll of an EMI film 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 integrating the EMI film with the functional film by feeding them into a gap between the first and second compression rollers.

This invention relates to a filter for a plasma display panel having excellent re-workability, durability, and reliability and a plasma display panel including the same. The filter for a plasma display panel of this invention is characterized by including an acrylic pressure-sensitive adhesive composition layer having adhesion after the lapse of a predetermined time period that is at least 1.5 times as great as initial adhesion. Since the inventive filter for a plasma display panel has low initial adhesion, when a defect occurs in a process of attaching the filter for a plasma display panel to an upper glass plate of the panel, a separation process may be easily conducted, and also adhesion increases with the lapse of time, thus exhibiting good durability and reliability without air bubbling and peeling.

摘要:
An electron emission display comprising an electron collector or metal member is provided. The electron emission display comprises an electron emission substrate comprising at least one electron emission device and an image forming substrate comprising at least one emission region and at least one non-emission region. Images are formed in the emission regions by the collision of electrons emitted from the electron emission devices with the emission regions. The image forming substrate further comprises a metal layer positioned on at least the emission regions, and at least one electron collector positioned in the non-emission region. The electron collector may comprise first and second ends, wherein the first end is attached to the image forming substrate and the second end faces the electron emission substrate. The electron collector stabilizes the metal layer and fluorescent layers, thereby reducing arc and maintaining uniform brightness by re-directing scattered electrons toward the fluorescent layers.
