Problems solved by technology

[0005] However, film filters are less capable of blocking or alleviating external impact applied to the front of the PDP than glass filters
Therefore, a PDP having a conventional film filter may cause malfunction and external deformation due to external impact applied to the front of the PDP

Abstract

A film unit which can protect a screen of a display device by absorbing and spreading an impact applied from the outside of the display device, and a plasma display panel having the film unit. The film unit includes a base film 10 having a predetermined area and thickness and provided with a plurality of openings 14 formed therein; and a cover layer sealing tops of the plurality of openings thereby forming self-elasticity by an air layer trapped within the closed space of the openings.

Description

technical field [0001] The present invention relates to a film unit which can protect a screen of a display device by absorbing and dispersing impact applied from the outside of the display device, and a plasma display panel having the same. Background technique [0002] Since a plasma display panel (PDP) is larger in size and smaller in thickness than a CRT, the PDP has been continuously researched and developed as one of the next generation display devices. [0003] Since the PDP is driven by discharge, it radiates strong electromagnetic waves, which affect other electronic devices. Therefore, it is necessary to shield electromagnetic waves radiated from conventional PDPs below a standard value. To this end, most conventional PDPs employ a front filter that shields electromagnetic waves and near-infrared light, and enhances bright room contrast by reducing reflectance of external light. [0004] The front filter can be classified into a glass filter formed with glass and...
