Description
Technical field
The invention relates to a kind of ceramic harden structure, a kind of especially ceramic harden structure suitable for contact panel.
Background technology
Currently with the element risen using range of the products such as intelligent mobile phone, tablet PC, make with contact panel
Additional function and its demand application surface also increasingly increase.And the known contact panel is typically more using clear glass sheet material or saturating
Bright plastic sheet etc. mainly forms one of component as panel, though can in cost of manufacture in accordance with the keyholed back plate of economy, only, sheet glass
Material is real more fragile in hardness, and easily by sharppointed article scratch, even influences its transparency and component outward appearance, edge this, be
The wearability so that contact panel is increased, subsequently it is easy to the surface of glass sheet or plastic sheet to be coated with or plated film
Method sets one layer of resistance to knifing, to reach the effect of scratch resistance.However, censure because of its lower hardness so the effect of scratch resistant can not be had concurrently.
In addition, user is to protect the contact panel of product, and the method for generally known pad pasting is used, and in the contact panel
The surface of clear glass sheet material or the surface of transparent plastic sheet material layer of plastic film is set, and well-known plastic film is generally divided into
High light-transmissive film and the class of frosted film two；Wherein, though use high light-transmissive film can so that the contact panel overall optics taste become compared with
To be clear, only, the material of its high light-transmissive film is more soft, and easily attachment is infected with fingerprint or extraneous dirty thing etc. and then influenceed overall
Perception, edge this, just must often change；Wherein, though can be apt to uniformly be distributed many molecules with it using frosted film
The relation of elements characteristic, and further improved the problems such as fingerprint or extraneous dirty thing etc. are infected with attachment, only, censure because of its translucency
Overall optics taste effect that is relatively low and causing the contact panel indirectly is non-to reach expected effect.
To improve quality and its work(such as the scratch resistance of foregoing carried contact panel, scratch resistant, high transmission rate and anti-fingerprint contamination
Effect, just has designer it is further proposed that using monocrystalline sapphire (monocrystalline sapphire carried in the present invention is made up of aluminum oxide)
For essential element, and one of base material of the contact panel is formed, even, a kind of sapphire paster is also made, it is copied public affairs
Know the method for the attachments such as glass patch or plastic adhesive film fitting, to be arranged at the surface of the contact panel, though because it is compared to public affairs
Under the aspect for knowing clear glass sheet material or transparent plastic sheet material, and with more high light transmittance, coefficient of heat conduction height, electric insulating quality
The advantages that good, mechanics good mechanical property, high rigidity, high-wearing feature and resisting wind erosion etc., only, because its processing technique equipment investment into
This high, highly energy-consuming, production cycle length, high-purity raw shortage etc. factor, make it be intended to the realization largely produced in industry
Actually it is not easy；Meanwhile sapphire has considerable degree of hardness, rather than soft and tool is preferably flexible such as well-known plastic pad pasting
Property, and the processing cost for causing the contact panel is increased.Therefore it is comprehensive it is foregoing carried, it is actually to be improved.
The content of the invention

It is able to lifting associative perception and answers yield and its effect.
To achieve the above object, ceramic harden structure provided by the invention, its include a matrix, one first antireflective coating,
One first coheres film layer, a conductive film layer, one second coheres film layer, one second antireflective coating and a ceramic layer；Wherein, the base
Body is a glass substrate；Wherein, first antireflective coating set between the matrix and this first cohere film layer between, to provide
The effect of light transmittance gain of the ceramic harden structure；Wherein, the conductive film layer, which is set, is attached to this and first coheres the another of film layer
Side simultaneously corresponds to first antireflective coating, and to aid conductive, the ceramic harden structure is electrical；Wherein, this second coheres film layer
The opposite side for being attached to the conductive film layer is set and corresponds to this and first coheres film layer；Wherein, second antireflective coating is set
Adhere to this second to cohere the opposite side of film layer and correspond to the conductive film layer, increase to provide the light transmittance of the ceramic harden structure
The effect of beneficial；Wherein, the ceramic layer, which sets the opposite side for being attached to second antireflective coating and corresponds to this, second coheres film
Layer, to lift the preferably translucency gain of the ceramic harden structure, coefficient of heat conduction, electric insulating quality, hardness property, wear-resisting
Property and resisting wind erosion and other effects.
In summary, the effect of of the invention is with feature, by the ceramic harden structure is in mainly polycrystalline transparent ceramic
Rotating fields and its have preferably translucency gain, the coefficient of heat conduction, electric insulating quality, hardness property, wearability and weather-proof concurrently
Property and other effects, meanwhile, the process production techniques of the known contact panel are further substituted with, to improve the contact panel because of script work
Time-consuming etc. the economic effect for not being inconsistent cost keyholed back plate of high cost feedstocks, highly energy-consuming and high production cycle attached by skill production technology
Benefit, to reach expection effect and purpose that the present invention is put forward.
