摘要： There is provided a PDP filter for absorbing near infrared ray capable of significantly reducing the kind and amount of dyes that are used to block a near infrared ray (NIR) emitted from PDP, the filters having physical properties that are improved when compared to conventional PDP filters for absorbing near infrared ray in which a large amount of 2, 3 or more dyes are used to block wide NIR spectra. The PDP filter includes a dye whose maximum absorption wavelength to a near infrared ray ranges from 880 to 1000 nm, and preferably from 900 to 960 nm. The PDP filter can be useful to improve its productivity, reduce the manufacturing cost and prevent the decrease in the light transmittance by unnecessary dyes.

摘要： 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.
