The filter of above-mentioned plasma scope (PDP), the anti-reflection layer that utilizes vacuum continuous magnetron sputtering method to be coated with on the plastic film aspect of compound prevention coatings oxidation or erosion on the coatings is TiO2 or Nb2O5/SiO2 two membranes system or TiO2 or Nb2O5/SiO2/TiO2 or Nb2O5/SiO2 four layer series.As previously mentioned, filter is an optics, the reflectivity that reduces by two air interface can greatly improve the optical index of filter and the image of display, the color index, adopt vacuum continuous magnetron sputtering method to make filter obtain the antireflective coatings, compare with tradition and prior art, especially with usefulness sol-gel process and organic coating method ratio, the production efficiency height, thickness and optical index are easy to control, production cost is low, and particularly the AR of four layer series (antireflection) coating makes filter single face reflectivity can drop to below 0.5%, two membranes system also can reach below 2.5%, is preferably below 1.5%.Adopt the collocation of this filter and display screen; can greatly improve the optical index of display; particularly image definition and contrast; because of between display and the filter because of reflectivity below 0.5%; basic areflexia phenomenon; substantially the image that exists between having eliminated repeatedly reflects and phenomenon that image definition is reduced; this filter collocation is arranged; can change and worry that image is clear inadequately and filter is attached to the technical scheme of eliminating the air gap on the display screen, filter is played being worth the protective effect of high display screen anticollision.
The filter of above-mentioned plasma scope (PDP), on the another side of glass substrate, be compounded with one deck plastic film, in deposition on the another side of glass substrate and/or on the plastics face or be coated with that antireflective is anti-reflection, oxygen obstruct, UV Absorption, increase the organic layer of hard scratch resistance, antistatic, antifog at least a function.In order to improve the optical property index of filter, in the face of display screen with in the face of watching face all to need reducing the reflectivity of glass substrate and plastics face, need carry out antireflective to the surface and handle, so that image is more clear, the contrast that improves display screen.The useful life of filter is most important to be to protect silver or silver alloy to belong to the not oxidated and erosion of layer; therefore protection not oxidation of dyestuff and light aging need adopt the coating protection of oxygen barrier function and coating need increase UV absorbers to reduce its light, oxygen aging to it.Because of plastic membranous layer surface pencil test hardness is HB, scratch resistance not, the easy generation in surface static easily adheres to dust in addition influences brightness of display screen and image quality, therefore need add the antistatic auxiliary agent and increase hard scratch resistant auxiliary agent by organic coating, because filter can be with arbitrary in the face of display screen, and and the air gap arranged between the display screen, might this simultaneously produces knot mist phenomenon in short-term in the face of display screen at filter because of the variation of temperature and humidity, need increase the fog resistance energy of this face in order to improve the filter quality, realize that this performance also needs organic coating and adds antifog prescription and auxiliary agent.The best way is the high transparent resin at above-mentioned surface-coated heat or photocuring, wherein preferentially select oleic series coating for use, and need add above-mentioned auxiliary agent and prescription therein because of function, this existing disclosed formula technique of various maturations is selective, adopt acrylic resin, the single face reflectivity preferably can reach 2% less than 3%, pencil hardness reaches 2H, preferably can reach 5H.
The filter of above-mentioned plasma scope (PDP), the anti-reflection layer that utilizes vacuum continuous magnetron sputtering method to be coated with on the another side of glass substrate and/or plastics face is TiO2 or Nb2O5/SiO2 two membranes system or TiO2 or Nb2O5/SiO2/TiO2 or Nb2O5/SiO2 four layer series.
The filter of above-mentioned plasma scope (PDP), the another side of glass substrate is by the binding agent compound one deck plastic film that bonds, and the plastics face deposits that antireflective is anti-reflection, oxygen barrier performance, UV Absorption, increase the organic layer of hard scratch resistance, antistatic, antifog at least a function.The compound one deck plastic film of bonding on the glass substrate of coatings another side can make filter have the ability that high strength more and anticollision destroy.But owing to increased one deck plastics face than aforesaid filter more; and the hardness of face only reaches the HB pencil hardness; therefore need on the plastics face, increase hard scratch resistance function and antireflective function at least; if the 596nm yellow characteristic light absorbing dyestuff of filter; and the dope dye resin bed is capped below this layer plastic membranous layer; also should increase oxygen barrier in the coating and/or UV Absorption function on this plastics face, not destroyed by photooxidation resistance as far as possible to protect the dyestuff under its covering.Because it is the most surperficial that the plastics face is in, need be at its surface anti-static even anti-caking mist, therefore with these functions that need of the easiest realization of organic coating, organic coating heat and/or the easiest realization above-mentioned functions of light-cured acrylic resin.
The filter of above-mentioned plasma scope (PDP), utilize the vacuum magnetic-control sputtering method to be coated with the anti-reflection layer on the organic layer of deposition on the plastics face of the another side of glass substrate or coating, they are TiO2 or Nb2O5/SiO2 two membranes system or TiO2 or Nb2O5/SiO2/TiO2 or Nb2O5/SiO2 four layer series.Utilize organic layer to realize aforementioned functional at the plastics face, but the antireflective of organic layer is limited in one's ability, can be reduced to 2.5% at most.If filter need improve light transmittance and reduce reflectivity, adopting above-mentioned AR film system two-layer or four layers is the best-of-breed technology scheme, and production is continuous, efficient is high, cost is low.Particularly on existing organic layer, plate again and state film, can state film higher pencil hardness is arranged, can reach more than the 3H than directly plating at the plastics face, if existing organic layer has reached 3H, then coatings can reach 5H, and single face reflectivity 2 tunics systems can reach below 2%, and four layer series can reach below 1%.
The filter of above-mentioned plasma scope (PDP), the absorbing dye of the yellow characteristic light of 596nm is in the molten resin glue that is mixed in acrylic acid series, independent film forming, this rete be coated on the coatings or the glass substrate of coatings another side on or between plastic film and the adhesive layer.In order to make dyestuff stable as far as possible under the effect of light oxygen; improve its function life-span; particularly reduce because of other of the trace metal ion in 596nm yellow characteristic light absorbing dyestuff and the miscible material under the heat effect of light oxygen and its molecule rock-steady structure of destructible and influence ion; the effect of the factor; with dyestuff and the higher independent film forming in the molten mixed back of organic binder material of purity; reduce with the molten of pure organic materials not and mix; can improve useful life; can reduce the cost of material of other organic materials again, this is the important technology safeguard measure that dyestuff will stand the strong illumination in 60,000 hour useful life of display.
The filter of above-mentioned plasma scope (PDP), the absorbing dye of the yellow characteristic light of 596nm are in the molten adhesive layer that is mixed between plastic film and the glass substrate or in the adhesive layer between plastic film and the coatings.With direct molten being mixed in the binding agent of dyestuff, convenient production, technological process is simple, when pasting plastic film, utilize dyestuff in binding agent, just to finish the dye resin layer coating simultaneously, but need the high dyestuff of stable performance and purity, the material of binding agent also requires quality higher, on the existing market, there has been a large amount of binding agents can reach requirement, the acrylate pressure sensitive adhesive bonding agent of particularly adopting light and heat to solidify, can not only satisfy stay-in-grade requirement, can raise the efficiency greatly simultaneously, the minimizing dye resin layer applies and reduces cost.
The filter of above-mentioned plasma scope (PDP), adding between molten mixed resin bed of the absorbing dye of the yellow characteristic light of 596nm and the plasma display or in any organic layer between the extraneous natural light irradiation face has ultra-violet absorber.Ultraviolet light in that can absorb that display sends and the natural daylight to be reducing the irradiation of ultraviolet light to dyestuff, protection dyestuff performance, keep dyestuff absorb 596nm yellow characteristic light ability and keep the redness and the green colorimetric purity and bright-coloured of display.Plasma display is provided with the filter of any described plasma display (PDP) of claim 1 to 11 before the plasma display.
Plasma display of the present invention, filter be that the plated film face of 13 layers or 17 layers coatings of basic rete is in the face of plasma display with silver or silver alloy.
Above-mentioned plasma display, filter be that the another side of plated film face of 13 layers of basic rete or 17 tunics is in the face of plasma display with silver or silver alloy.Filter all is coated with the AR antireflection layer because of the two sides; the conduction coatings be the EMI layer around post the copper-foil conducting electricity that is in contact with it and glass substrate be the U type and coat; can be communicated with the chassics earth circuit of display equipment on the filter two sides as the conduction extraction electrode; so filter can be faced display with any one side easily; the glass that is coated with the AR anti-reflection layer is to watching face; another side is compounded with the plastic film that is coated with the AR anti-reflection layer; filter leaves the certain gap ratio of display as 3 to 5 millimeters; can not only not influence picture quality, can play the effect of protection screen.Particularly glass substrate be tempering or half tempered, have very high intensity, costly display screen is played best protective effect.Install if filter is close to display, can reduce the gross thickness of display equipment.
Above-mentioned plasma display is to rely on organic layer on binding agent or the filter not have the air gap to be pasted together between filter and the plasma display.Utilize binding agent and display to be pasted together filter, the AR anti-reflection coating of binding face can be reduced in air gap between the elimination, can reduce the thickness of glass substrate, can save cost, and the image between eliminating fully reflects repeatedly and improves picture quality and contrast.Because the filter finished product has the blocking capability of ultraviolet light, attaching process can not adopt the optic-solidified adhesive of acrylic acid series to realize the bonding applying of display, but binding agent needs long-term anti-photooxidation and thermal oxidation again, so the pressure sensitive adhesive of preferred acrylic acid series or organosilicon alkanes heat-curable glue realize that it is technical scheme preferably that bonding between them is fitted.
