For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to the embodiment of the utility model application, structure, feature and effect thereof, be described in detail as follows.In the following description, the not necessarily same embodiment that different " embodiment " or " embodiment " refers to.In addition, special characteristic, structure or feature in one or more embodiment can be combined by any suitable form.
As shown in Figure 1, a kind of touch screen that an embodiment of the present utility model proposes, comprises touch layer 10 and cushion 20.The front of described touch layer 10 is for the touch operation pointed to realize good in interactive function, and described cushion 20 is arranged on the back side of described touch layer 10, and described cushion 20 is connected with described touch layer 10 close contact.Wherein, described cushion 20 is one deck mantle, and the thickness of described cushion 20 is 1 ~ 2 micron.When the front of described touch layer 10 is subject to impulsive force, the stress that described impulsive force produces by described cushion 20 spreads to its surrounding.Find after deliberation, OGS touch screen of the prior art is easily split reason and is that its back side is after every technique (plated film-exposure-development-etching), the glass of touch screen at high temperature easily produces ion-exchange, causes the stability of touch screen glass, compactness to weaken.Therefore, when touch screen glass surface is subject to impacting, glass can produce reclinate strain, that is: its upper surface shrinks because being subject to compressive stress, and its lower surface extends because being subject to tension stress.Wherein the tension stress of the contact ring normal direction of stress point and glass is maximum.The lower surface of glass can produce stress and concentrate under tension stress effect, and when stress reaches its fracture toughness, fracture occurs.
The technical scheme that the utility model provides is by arranging described cushion at the back side of described touch layer, and described cushion is connected with described touch layer close contact, because described cushion is one deck mantle, therefore when the front of described touch layer is subject to impulsive force, the stress that described impulsive force can produce by described cushion spreads to its surrounding, thus makes described touch layer not easily broken.Simultaneously because the thickness of described cushion is only 1 ~ 2 micron, and the thickness of described touch layer is approximately 0.55 millimeter, described cushion is relatively negligible with the thickness of described touch layer, and therefore described cushion can not significantly increase the thickness of described touch screen.
Further, the material of described touch layer can be glass.Thickness of glass at present for touch screen is about 0.55 millimeter, and GFF structure is the structure of one deck glass and double-layer films, and the thickness of every layer film is about 0.07 millimeter; And OGS structure is one deck glass and one deck ito thin film.ITO is the abbreviation of IndiumTinOxides, as nano indium tin metal oxide, has good electric conductivity and the transparency, can cut off harmful electron irradiation, ultraviolet and far infrared.Therefore, be sprayed on after in glass, plastics and electronic display, while enhancing electric conductivity and the transparency, cut off harmful electron irradiation and ultraviolet, infrared.Because the thickness of above-mentioned ito thin film is at Nano grade, therefore almost negligible.As can be seen here, OGS structure compare GFF thickness can be much thin.For OGS touch screen, the thickness of described touch layer 10 is the integral thickness of described touch screen, and therefore the thickness of described touch layer 10 is not more than 0.55 millimeter, namely represent the integral thickness of described touch screen may be limited to 0.55 millimeter or within.Although the touch screen in the present embodiment adds described cushion 20, but the thickness due to described cushion is only 1 ~ 2 micron, therefore the thickness of described cushion 20 is also negligible, thus when making the thickness of described touch screen constant, its intensity improves greatly.
Further, described cushion 20 is one deck plated film at the back side of described touch layer 10, and that is, described cushion 20 realizes close contact by the technique of coating with described touch layer 10 to be connected.Coating method mentioned here mainly comprises: plating, electroless plating, mechanical plating, Vacuum Deposition etc.
Wherein, plating utilizes the principle of electrolysis by the method for electric conductor layer overlay metal.Except electric conductor, plating also can be used on the plastic cement of special processing.The aesthetic property and the current density size that are plated object after plating have relation, and can in operating current density range, current density be less, and the object be plated just can be more attractive in appearance; Otherwise then there will be some irregular shapes.
Electroless plating also claims electroless plating or autocatalytic plating, be when without when impressed current by suitable reductive agent, make reducing metal ions in plating solution become metal, and deposit to a kind of coating method of piece surface.Electroless plating technology is under the catalytic action of metal, by the metallic deposition process of controllable redox reaction.Compared with plating, electroless plating technology has that coating is even, pin hole is little, do not need DC power supply device, can deposit on nonconductor and have the features such as some property.In addition, because electroless plating technology discharging of waste liquid is few, environmental pollution is little and cost is lower, progressively replaces plating in a lot of fields, becomes a kind of process of surface treatment of environment-friendly type.At present, electroless plating technology is widely used in the industry such as electronics, valve manufacture, machinery, petrochemical complex, automobile, Aero-Space.
Mechanical plating is that a kind of physics, chemisorption deposition and mechanical collision of utilizing at normal temperatures and pressures makes metal powder form the technique of coating at surface of the work.Metal powder can be metallic zinc, zinc-aluminium, zinc-Xi or other non-ferrous metal and alloy.Typical mechanical plating craft is the cylinder part through treatment before plating being put into mechanical rotation, adds water and impact media (glass ball), and rotary drum forms a fluidised form environment having collision and rub stone roller effect with the hands.Add metal powder and medicament according to predetermined thickness of coating, under the acting in conjunction of chemical agent and mechanical collision, make the surface of part form coating.The coating of mechanical plating is without hydrogen embrittlement, and thickness is even, and coating microstructure is fine and close, and hole is few, and corrosion stability comparatively electrodeposited coating is good, but outward appearance is level and smooth, bright not as electrodeposited coating.The metal being suitable for mechanical plating has soft metal or their alloys such as zinc, cadmium, tin, aluminium, copper; The part being suitable for mechanical plating has the findings such as screw, nut, pad, iron nail, pin, reed and to the high-strength steel of hydrogen embrittlement sensitivity and spring.Workpiece shapes has a definite limitation for the workpiece being unsuitable for barrel plating, such as, has the position of protruding tip or the yielding workpiece of very thin appearance etc. all can not adopt mechanical plating on.
Vacuum Deposition mainly comprises vacuum evaporation, sputtering plating and ion plating several types, they are all adopt under vacuum, by distill or the mode such as sputtering at the various metal of plastic surface deposition and nonmetal film, very thin overlay coating can be obtained by such mode, there is the outstanding advantages that the fast adhesion of speed is good simultaneously, but price is also higher, the metal types can carrying out operating is less, is generally used for the functional coating of higher gears product.
In practical operation, which kind of method to form described plated film especially by, can consider according to the combined factors of each side such as the material of wanted coating and the material of plated film, in addition price, not do concrete restriction here.
Further, described cushion 20 is organic resin material.Resin is a kind of from various plants, the particularly secretion of hydrocarbon (hydrocarbon) class of coniferae.Because the chemical constitution that it is special, and can use as the material such as latex paint and adhesive, therefore resin has higher commercial value.Resin can be divided into natural resin and synthetic resin two kinds.Along with the development of chemical industry, have and much produced by the polymkeric substance of Prof. Du Yucang, the chemical property of some polymkeric substance and physical property can be very similar with natural resin, and therefore, polymkeric substance can be called as synthetic resin.Resin can be divided into carbochain polymer, heterochain polymer and elemento-organic polymer by molecular resin main chain composition.Elemento-organic polymer and organic resin, refer to not necessarily containing carbon atom on main chain, primarily of the atomic building of the elements such as silicon, oxygen, aluminium, titanium, boron, sulphur, phosphorus, as organosilicon.
