Problems solved by technology

[0010] However, the method of first coating the thermoplastic resin on the electromagnetic shielding net 132 is to carry out block coating (Sheet Coating) of the thermoplastic resin, so the coating equipment used is very expensive, so the production cost of the process will be increased; in addition , regardless of vacuum and high temperature methods, or high temperature and high pressure methods to remove air bubbles, the required process costs are higher and the conditions are stricter
Moreover, when air bubbles are extracted in the vacuum process, it is not economical to even produce them in batches of single wafers, and it will lead to an increase in production costs.

[0083] As shown in FIG. 3 , the manufacturing method of the optical filter of the present invention includes: setting a metal mesh layer step (S100), coating a pressure-sensitive adhesive on a first filter film step (S200), and bonding the first filter film step (S200). The step of filter film and the metal mesh layer (S300).

[0084] Please refer to FIG. 3 and FIG. 6 , in the step of disposing a metal mesh layer ( S100 ), the metal mesh layer 211 is disposed on a first surface 213 of a first resin layer 212 to form an anti-electromagnetic wave film 21 . The first resin layer 212 has a second surface 214 opposite to the first surface 213 .

[0085] Wherein, the first resin layer 212 is polyethylene terephthalate (PET) with a thickness of about 75 to 125 μm. The metal mesh layer 211 is formed by exposure, development and etching, with an aperture ratio of 85-95%, and the material can be copper. In this embodiment, in order to achieve good penetration efficiency of visible lig...

[0100] Please refer to FIG. 9, the optical filter manufacturing method of the present invention includes a step of setting a metal mesh layer (P100), coating a pressure-sensitive adhesive on a substrate step (P200), and bonding the substrate and the metal mesh layer step ( P300).

[0101] Wherein, the step of setting a metal mesh layer ( P100 ) is the same as the step of setting a metal mesh layer ( S100 ) in the first embodiment, and will not be repeated here. In addition, the same component symbols in this embodiment represent the same components, and detailed component descriptions will not be repeated here.

[0102] As shown in FIGS. 9 and 10 , in the step of coating a pressure-sensitive adhesive on a substrate (P200), a pressure-sensitive adhesive 22 with a Ball Tack Value of less than 9.5 is coated on the substrate 24 . Among them, cheaper continuous coating equipment can be used for coating.

[0103] As shown in FIGS. 10 and 11 , in the step of bonding the substrate ...

Abstract

This invention refers to a method for making optical filter piece for electric slurry displace panel, which contains setting a metal screen layer on first surface of first resin layer, said resin layer having a second surface, coating a pressure sensitive glue with less than 9.5 of ball viscosity value on first light filter film, adhering first light filter film and metal screen layer.

Description

technical field [0001] The invention relates to a method for manufacturing an optical filter, in particular to a method for manufacturing an optical filter for a plasma display panel. Background technique [0002] A plasma display panel (Plasma Display Panel, PDP) is a flat-panel display that emits visible light through the conversion of an inert gas into a plasma discharge. It has the characteristics of thin thickness, high image quality, and wide viewing angle. There is a tendency to gradually replace cathode ray tube (Cathode Ray Tube; CRT) displays in the field. [0003] In addition to emitting visible light, plasma display panels also emit neon light (Neon Light, with a wavelength of about 560-620nm), electromagnetic waves (Electro-Magnetic Wave), and near-infrared rays (Near Infrared Ray, with a wavelength of about 800-1000nm) etc. Among them, neon light will interfere with the color rendering of the display, and excessive electromagnetic waves are harmful to the hum...
