Embodiment 1

[0063] figure 1 The structure schematic diagram of the plasma display filter of the present embodiment 1 is provided, with reference to figure 1 , the coating laminate EO is coated on the light-transmitting base layer L0 by magnetron sputtering. The structure of the coating laminate is: on the light-transmitting base layer L0, titanium dioxide (TiO 2 ) film layer 11, AZO film layer 12, silver and silver alloy (Ag) film layer 13 constitute the basic lamination, and then repeat the above basic lamination twice, that is, there are three layers of silver and silver alloy (Ag) film layers in total, thus forming The coating laminated body E0. Finally, coat a layer of titanium dioxide (TiO 2 ) film layer 11-1. The transparent base layer L0 is transparent glass (but the present invention is not limited thereto). Considering the anti-oxidation protection of the silver-containing metal layer during the production process, titanium dioxide (TiO 2 ) layer 11-1 is sputtered with a ce...

Embodiment 2

[0068] figure 2 It is another schematic diagram of the structure of the plasma display filter in Example 2 of the present invention. This Example 2 is basically the same as Example 1, except that the coating laminate structure E1 is: on the light-transmitting base layer L0, titanium dioxide ( TiO 2 ) film layer 11, a silver and silver alloy (Ag) film layer 13, and a transparent metal oxide layer 12 are basically stacked. Repeat the above-mentioned basic lamination twice (or three or four or more times), that is, there are three (or four or five or more) silver and silver alloy (Ag) film layers in total, thereby forming the laminated film Body E1. Its product function is substantially identical with embodiment 1, and advantage is to utilize transparent metal oxide layer (preferably AZO, also can be SiO 2 , MgO, Sb 2 o 3 , SnO 2 、Al 2 o 3 , Y 2 o 3 , La 2 o 3 、In 2 o 3 , ZnO(Al), NiCrOx, ZnO, ZrO 2 At least one of , ITO, AZOY, X in NiCrOx is 1-6) to protect the s...

Embodiment 3

[0070] image 3 It is a schematic diagram of another structure of the plasma display filter according to Embodiment 3 of the present invention. Embodiment 3 is basically the same as Embodiment 1 and Embodiment 2, except that the light-transmitting base layer L0' is a contrast-enhancing film structure L. The contrast-enhancing film structure L uses a 180-200um PET film as the base layer L1, which is coated with a photocurable or thermosetting resin, and the transparent geometric structure LE2 is formed by embossing. The structure of the transparent geometric body LE2 is as follows: Figure 7 ~ Figure 12 As shown, the height of the geometry is 175um, the width of the light entrance LE4 is 75um, the width of the light exit LE1 is 50um, the length is infinitely long to the edge of the basement membrane, and the long side is horizontal. The LE perspective view of the transparent geometry structure layer is as follows Figure 4 shown. Then, on the cured resin structure, coat a ph...

Abstract

The invention provides a plasma display filtering plate which comprises a light transmitting substrate LO, a coating overlapped body coated on the light transmitting substrate LO, a titanium dioxide coating (11-1) coated on the coating overlapped body, a light transmitting substrate LO' coated on the titanium dioxide coating (11-1), a metal film contacting with the coating and used as a led-out electrode, and a film layer or a glue layer compounded or melted together with the light transmitting substrate LO or the light transmitting substrate LO', wherein the film layer or the glue layer is made by adding absorbing dye and has maximum absorbing peak valleys of yellow characteristic of 580nm to 600nm. The invention has the functions of display emitting color regulation, electromagnetic isolation (EMI), near infrared light cut (NIR-cut), Ne characteristic light cut (Ne-cut), light transmittance improvement, and the contrast of the plasma display, can be overlapped with most of other methods of contrast improvement without high disturbance and enables the high contrast of the original psalm display to be increased again. The invention also provides a psalm display using the filtering plate.

Description

Technical field: [0001] The present invention is related to the optical filter in the display device, is related to the optical filter with anti-electromagnetic radiation and light filtering functions in the plasma display (PDP), and is related to the optical filter with the contrast enhancement function in the plasma display (PDP) It is related to the plasma display device using the filter. Background technique: [0002] The anti-reflection, anti-electromagnetic radiation and filtering functions of the current PDP filter plate are formed in this way: a plastic film plated with an anti-reflection film layer is pasted on the outer surface of a piece of glass, and an anti-reflection film formed by two layers of plastic is pasted on the other side. Diaphragms for electromagnetic radiation and light filtering functions. One of the layers is to form a metal conductive grid on the diaphragm by photolithography or wire mesh wiring method to form an anti-electromagnetic radiation f...
