Description
Technical field
The present invention relates to a kind of method for making of monolithic substrate capacitance formula touch-screen, belong to the electronic product field.
Background technology
Touch-screen (touch screen) is called again " touch screen ", " contact panel ", it is a kind of induction type liquid crystal indicator that receives the input signals such as contact, when having contacted the graphic button on the screen, haptic feedback system on screen can drive various hookup mechanisms according to the formula of programming in advance, can be in order to the push button panel of dessert machine tool formula, and produce lively visual and sound effects by liquid crystal display picture.Touch-screen is as a kind of up-to-date computer input apparatus, and it is the simplest, convenient, natural at present a kind of man-machine interaction mode.It has given multimedia with brand-new looks, is extremely attractive brand-new multimedia interactive equipment.
Existing touch-screen has resistive touch screen, capacitive touch screen, infrared-type touch-screen and ultrasonic surface formula touch-screen.Wherein, capacitive touch screen, because it has the advantages such as the life-span is long, degree of accuracy is high, the volume production feasibility is strong, has been widely applied in each field, and so-called capacitive touch screen is exactly the touch-screen that a kind of peculiar electrical characteristics of utilizing human body reach the touch control operation purpose.
Monolithic substrate capacitance formula touch-screen is on a laminar substrate, directly to prepare conductive pattern to form touch sensing, to reach the purpose of touch control.That monolithic substrate touch-screen product has is simple in structure, transmittance is high, frivolous, low cost and other advantages.Existing monolithic substrate capacitance formula touch screen structure comprises a transparency carrier, one dielectric ink layer is arranged on transparency carrier, on the dielectric ink layer, evaporation has a transparency conducting layer, and a dielectric isolation layer is arranged on transparency conducting layer, and dielectric isolation layer is provided with metal and builds bridge and trace layer.
The method for making of existing monolithic substrate capacitance formula touch-screen is: by a sheet of substrate intensive treatment, large plate base colorful insulation ink layer is made, large plate base multilayer touch-control graphic making, and large plate base cuts into small size.Because cutting is carried out after the touch-control graphic making, if hardness is too high, in cutting process, easy fragmentation and edge are impaired extremely serious, and easy damaged transparency conducting layer, thereby can cause producing the sheet qualification rate, greatly reduce, therefore, in prior art, the strengthening hardness of touch-screen does not reach optimum efficiency.
Summary of the invention
Technical matters to be solved by this invention is: a kind of method for making of monolithic substrate capacitance formula touch-screen is provided, has solved the problem that existing monolithic substrate capacitance formula touch-screen yield rate is low, intensity is low.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of method for making of monolithic substrate capacitance formula touch-screen, the method sets gradually dielectric ink layer, transparency conducting layer on the substrate after intensive treatment; Transparency conducting layer is carried out to the exposure imaging etching, form the touch-control circuit plate; Described touch-control circuit plate is cut into to the touch controllable function sheet; The touch controllable function sheets of at least two are carried out to the stacked stepped construction that fits into; And this stepped construction is carried out to the chemical enhanced processing of secondary; Stepped construction after processing is split as to independently touch controllable function sheet.
Described touch controllable function sheet also comprises before stacked laminating: to the touch controllable function sheet hole, edging, chamfered.
Described transparency conducting layer is arranged on the dielectric ink layer by a kind of mode in vacuum evaporation, sputter plating, ion plating.
The touch controllable function sheet of described at least two is by insulation optical clear colloid or carry out stacked laminating without shadow glue.
Preferably, described substrate is glass substrate.
Compared with prior art, beneficial effect of the present invention is:
Carry out strengthening process twice, solved the low problem of primary reinforcement hardness, make strengthening hardness reach optimum efficiency, after secondary hardening, the mechanical resistance pressure result can reach 4 times of primary reinforcement.
At first the touch-control circuit plate is cut into to the touch controllable function sheet, then by the stacked laminating to the touch controllable function sheet, carry out again secondary chemical enhanced, avoided like this touch controllable function sheet in the secondary hardening process, product is broken, edge strength is impaired, when effectively having improved intensity, improved product percent of pass.

Embodiment
Below in conjunction with the technical scheme of drawings and Examples to invention, be elaborated:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of method for making of monolithic substrate capacitance formula touch-screen, at first, carry out substrate 1 intensive treatment and print the dielectric ink layer in a side of this substrate 1; On described dielectric ink layer, transparency conducting layer is set; In a side that is coated with transparency conducting layer, by the exposure imaging etching, carry out the making of touch-control circuit 2, make the rear formation touch-control circuit of touch-control circuit 2 plate; Described touch-control circuit plate is cut into to a slice touch controllable function sheet 3 at least; The touch controllable function sheets 3 of at least two are carried out to stacked laminating by colloid 4; And the touch controllable function sheet after fitting 3 carries out the chemical enhanced processing of secondary.
The present embodiment colloid 4 is selected insulation optical clear colloids or without shadow glue.
Preferably, in order further to optimize the performance of touch controllable function sheet 3, described touch controllable function sheet 3 also comprises before laminating: to touch controllable function plate 3 hole, edging, chamfering, make touch controllable function sheet 3 be applicable to product demand.
Described transparency conducting layer is arranged on the dielectric ink layer by a kind of mode in vacuum evaporation, sputter plating, ion plating.
Mechanical resistance pressure after described touch controllable function sheet secondary is chemical enhanced for the strengthening before more than 4 times.
In order to make touch screen transparent Du Genggao of the present invention, preferably, described substrate is selected glass substrate.
The monolithic substrate capacitance formula touch-screen that utilizes this method to make, its hardness reaches optimum efficiency, after secondary hardening, after the test of mechanical resistance pressing detecting device, test result shows, the effect of its mechanical resistance pressure can reach before secondary hardening more than 4 times, efficiently solve the not high enough problem of the similar touch-screen hardness of prior art.
By the touch-control circuit plate being cut into to several touch controllable function sheets, and then to the stacked laminating of touch controllable function sheet, after laminating, carry out secondary chemical enhanced, avoided like this touch controllable function sheet in the secondary hardening process, product is broken, edge strength is impaired, when effectively having improved intensity, improved product percent of pass.Effectively evade after the conventional touch screen graphic making in cutting process the problems such as impaired serious, the product yield reduction of the easy fragmentation of product and edge strength.
