Embodiment Construction

[0029] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown.

[0030] In the following embodiments, a filter for a PDP device will be exemplified, but as above, the present invention is not limited thereto.

[0031] figure 1 It is an exploded perspective view of the PDP device 100 .

[0032] refer to figure 1 , the PDP device 100 includes a housing 110, a cover portion 150 covering the housing 110, a drive circuit board 120 housed in the housing 110, a panel assembly 130 including a light emitting unit and a PDP filter 140, and gas discharge occurs in the light emitting unit .

[0033] The PDP filter 140 may include an electromagnetic wave blocking layer including a material excellent in electrical conductivity and grounded to the case 110 through the cover 150 . Before the electromagnetic wave reaches the audience, the electromagnetic wave is released to the housing 110 through...

Abstract

A method of fabricating an external light blocking film for a display device is provided. The method includes a step of applying a curable resin in which a photochromic colorant is mixed on a backing of a transparent resin; a step of disposing a photo-mask having a predetermined pattern on the curable resin and then irradiating the photochromic colorant through the photo-mask with light having a first wavelength which makes the photochromic colorant color-changed; a step of removing the photo-mask and then curing the curable resin. The method can improve fabrication efficiency.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2007-0104721 filed with the Korean Intellectual Property Office on October 17, 2007, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an external light blocking film, a filter having the external light blocking film and a manufacturing method of the external light blocking film, more particularly, the present invention relates to an external light blocking film capable of improving bright room contrast and manufacturing efficiency, Filters and methods of manufacture.
