The present invention is characterized in that titanium metal material is directly sputtered on the surface of a display panel of the information display by using an ion sputtering plating mode to form the antistatic and anti-reflective coating layer used for adjusting the penetration rate. The sputtering thickness and density of the antistatic and anti-reflective coating layer are adjusted so as to achieve the effect of effectively adjusting the electrical conductivity of the antistatic and anti-reflective coating layer and the evenness of the penetration rate of the entire display panel.
Description
Technical field
The invention relates to a kind of method that on information display, forms the antistatic and ARC of adjusting penetrance, refer in particular to a kind of ion beam sputtering deposition mode of utilizing respectively, on the panel surface of information display, form titanium coating and silica membrane in regular turn, by thickness and the density of adjusting this titanium coating, effectively adjust the uniformity of penetrance on the electric conductivity of formed antistatic coating and the whole display floater.
Background technology
As everyone knows, the intensity of reflected light on the cathode ray tube (CRT) surface of general video display, the 4-8% that is about incident light, this reverberation is for long user, very easily cause the eye fatigue injury, and can reduce due resolution and color contrast on the video display, in addition, in the High Resolution and high image quality display popularized day by day now,, very easily on display surface, form electrostatic pressure because its driving voltage is general all up to 25KV, cause that micro dust particle is adsorbed on its surface in the atmosphere, destroy the image quality of display, and when in the low humidity zone, using this kind display, also made the user get shocked easily.So be generally and address the above problem, make video display meet relevant quality requirements, all can be on the display floater outer wall surface of cathode-ray tube, carry out anti-dazzle, antireflection and antistatic etc. surface treatment, by being coated with the method for most antistatic and ARCs, with effective minimizing light source reflex to the harmful effect that video image was caused, and the electrostatic pressure that significantly reduces on it to be accumulated.In recent years, because the popular image quality to display of consumption requires day by day to improve, the dealer of video display is there's no one who doesn't or isn't towards being target with the display that designs and manufactures more high-quality and level, therefore, the quality of the antistatic and anti-reflection effect of video display promptly becomes criticism quality major criterion just.
When making cathode-ray tube, employed antireflection and antistatic treatment generally with spraying, rotary coating or ion beam sputtering deposition mode, will contain antimony tin oxide (hereinafter to be referred as ATO, as tin ash antimony: Sb-SnO at present
2) or indium tin oxide (hereinafter to be referred as ITO, as: tin ash-indium sesquioxide composition: In
2O
3-SnO
2) the antistatic coating solution of composition, be coated on the outer surface of the display floater that is curved surface on the cathode-ray tube, to form an antistatic coating, on antistatic coating, be coated with the antireflection coating solution that contains silica (as siliceous gel) composition again, form ARC, to realize antistatic and antireflecting effect.
Be visible angle and the appearance and modeling of improving cathode-ray tube, will be curved display floater now and be designed to the flat sided straight horn shape, liked by the consumer.The structure of cathode-ray tube commonly used as shown in Figure 1-Figure 3, Figure 1 shows that widely used now flat square cathode-ray tube schematic diagram, the glass that is positioned at middle position on its display floater than the glass of its peripheral position for thin, the penetrance that causes its middle position glass is 80%, and the penetrance of peripheral position glass only is 68%, for the whole display floater that makes plane cathode-ray tube has than the uniform penetration rate, it generally is method by the penetrance that reduces whole display floater, approximately penetrance is reduced to 50%, to dwindle on the display floater gap ratio of glass penetrance between central authorities and peripheral position, make display floater present more uniform whole picture.
Figure 2 shows that the vertical section schematic diagram of general traditional color cathode ray tube 10, mainly comprise a sealed glass body 12, this canals of stilling 12 is provided with face glass 14, tube neck 18 and middle pars infundibularis 16, the inner wall surface coating fluorescence coating 24 of this face glass 14, this fluorescence coating 24 comprises most the unit and fluorescence units 241 that can distribute fluorescence respectively, be provided with most the electron guns 20 that are arranged in a linear in the tube neck 18 of the canals of stilling 12 of sealing, in order to produce three-color electron beam 22, electron beam 22 is through the control of a magnetic deflection scanning yoke, along level and vertical direction deviation, and focus on this fluorescence coating 24, when the three-color electron beam that produces when this color cathode ray tube 10 focuses on each unit and fluorescence unit 241 on these face glass 14 inner wall surface, this unit and fluorescence unit 241 will give out coloured light, to show video image on this face glass 14.
Figure 3 shows that tradition is applied to partial cutaway schematic on the display floater of color cathode ray tube with antistatic and ARC, the inner wall surface coating of this face glass 40 has fluorescence coating 42, and its outer wall surface is coated with coating 44.This fluorescence coating 42 is by most each intervals and be point-like or the unit and fluorescence unit of zonal distribution is formed.This coating 44 comprises the antistatic coating 46 and the outer field ARC 48 of internal layer, the surface of this antistatic coating 46 is provided with conducting element 50, by this conducting element 50 this face glass 40 is connected to earth terminal, the electrostatic charge of being accumulated with these face glass 40 outer wall surface of effective removal; This ARC 48 is in order to reduce these face glass 40 outer wall surface environment reflection of light to external world, to make on this face glass 40 to present video image more clearly.
Employed coating way is an example on the flat sided straight horn shape face-plate of a cathode-ray tube at present, except utilizing the ion beam sputtering deposition mode, outside the material that will contain antimony tin oxide, titanium and titanium nitride composition is coated on the display floater, it mostly is the antistatic coating that utilizes the conductive material that contains silver-colored palladium or silver-colored golden composition, by rotary rubbing method, it is sprayed on the display floater, to reduce the penetrance of whole front panel, and then dwindle the gap ratio of glass penetrance between central authorities and peripheral position, its major defect is:
Owing to use noble metal, its cost of manufacture is quite expensive, is not suitable for using widely.
At the defective of prior art, the inventor researchs and develops, and creates technical scheme of the present invention.
Summary of the invention
Main purpose of the present invention is to provide a kind of method that forms the antistatic and ARC of adjusting penetrance on information display, by the ion beam sputtering deposition mode, titanium metal material directly is coated on the panel surface of information display, form antistatic coating, on antistatic coating, utilize the ion beam sputtering deposition mode, sputter layer of silicon dioxide film, by adjusting the sputter thickness and the density of this antistatic coating, reach the inhomogeneity purpose of penetrance on the electric conductivity of the formed antistatic coating of effective adjustment and the whole display floater.
The object of the present invention is achieved like this: a kind of method that forms the antistatic and ARC of adjusting penetrance on information display, it is characterized in that: it is by the ion beam sputtering deposition mode, the direct sputter of titanium metal material on the panel surface of information display, is formed the antistatic and ARC of adjusting penetrance.
Be the ion beam sputtering deposition mode of utilizing on this antistatic coating, sputter has the layer of silicon dioxide film.The thickness of this antistatic coating is at 2-8nm.The thickness of this silica membrane is at 70-100nm.
