Problems solved by technology

[0004] However, the thickness of the tempered glass filter will significantly increase the weight and manufacturing cost of conventional PDPs
More importantly, the difference between the materials used to form the tempered glass filter and the PDP front substrate can cause dual reflection due to refraction, thereby degrading the image quality of the PDP
Furthermore, conventional tempered glass filters may exhibit insufficient bright-room contrast and include complex fabrication methods due to their complex structures (i.e., combined layers performing different functions).

Abstract

A filter assembly (10;20) includes a film type filter (17;27) with a base film (13;23) and a plurality of light absorption pattern units (11;21) thereon, and an adhesion pattern layer (15;25) attached to the film type filter. The adhesion pattern layer may include a plurality of protrusions, each having a convex lens shape, arranged in a zigzag structure with respect to the light absorption pattern units of the film type filter.

Description

technical field [0001] The invention relates to an optical filter and a plasma display panel using the optical filter. In particular, the present invention relates to an optical filter capable of enhancing brightness in a plasma display device. Background technique [0002] In general, a plasma display panel (PDP) refers to a flat panel display device that can display images using a gas discharge phenomenon, thereby providing superior display characteristics such as high brightness and contrast, clear Latent images, wide viewing angles, thin / large screen sizes, and more. [0003] A conventional PDP may include an optical filter having multiple thin layers. A conventional optical filter may be attached to the front substrate of the PDP in order to control external light transmitted therethrough in order to reduce light reflection, thereby improving the image quality and clarity of the PDP. A conventional filter such as a tempered glass filter may be formed with a uniform t...
