Description
Technical field
Touch screen technology field is the utility model is related to, the touch-screen prepared more particularly to a kind of photosensitive material.
Background technology
Touch-screen is a kind of input equipment for significantly improving man machine operation interface, has the advantages of directly perceived, simple, quick.
Touch-screen has been obtained for being widely applied in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system
System etc..The making of touch-screen at present still using transparent conducting glass and nesa coating as main material, completes the conducting wire of each layer
It is bonded together again in the form of optics glue laminating afterwards.
But with market to low cost requirement, the material and production process that present touch screen overlay structure uses it
It is more, it can not be dropped again in cost.
Utility model content
The purpose of this utility model is to provide a kind of touch-screen, and the touch-screen can effectively simplify manufacture craft and reduction
Material.Therefore, the utility model uses following technical scheme：
A kind of touch-screen, it is characterised in that the substrate layer including touch-screen, the photosensitive layer of integrated electrically conducting layer；With substrate layer
Order from the close-by examples to those far off is the first photosensitive layer, the first conductive layer, the second photosensitive layer, the second conductive layer.
Further, the substrate layer is the cover plate of touch-screen, or the individually optics of carrying touch induction circuit
Material；The cover plate and optical material can be glass or plastic material.
Further, first conductive layer is attached on the first photosensitive layer, and second conductive layer is attached to the second sense
On photosphere.
The conductive material range of choice of conductive layer includes tin indium oxide（ITO）, development, pass through evaporation, magnetron sputtering
Or the method for coating is prepared on photosensitive layer.
Photosensitive material in photosensitive layer dissolves in alkali lye to ultraviolet-sensitive；Photosensitive layer passes through the technique system that exposes, develop
The circuit pattern of conductive layer thereon is integrated in, the material has very high light transmittance and low resistance.
Further, connection, the second photosensitive layer are pressed on the conglomerate and substrate layer of the first photosensitive layer and the first conductive layer
Press and be connected to above the conglomerate of the first photosensitive layer and the first conductive layer again with the conglomerate of the second conductive layer.
Further, the first conductive layer and the second conductive layer have the lead-out wire of circuit to be pooled to one end respectively, then with flexibility
Wiring board connects.
Exposed under ultraviolet light after circuit pattern completes, it is necessary to put, to reach the stable purpose of photosensitive layer molecule.
Due to using the technical solution of the utility model, the utility model can be only by pressing, exposing, developing, cleaning
Several procedures can complete the making of touch sensor；Base material and the photosensitive material with conductive layer are only needed on material, no
Need optical cement（OCA）With other optical materials, it will be apparent that reduce material and the process that structure uses, life can be effectively improved
Produce efficiency and reduce the requirement of cost, realize that touch-screen is lightening, and because conductive layer can directly be pressed together on arbitrary smooth high temperature resistant
On material, the abnormity and curved surface effect that can realize touch-screen simultaneously make, as touch-screen use answers the continuous extension in field, for
Flexible bendable touch-screen demand also constantly increases, and the utility model can solve the demand of flexible bendable characteristic.

Embodiment
In order that those skilled in the art is better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings and have
Body case study on implementation is described in further detail to the utility model.
Substrate layer 101, the photosensitive layer of integrated electrically conducting layer of reference picture 1, touch-screen of the present utility model, including touch-screen；
It is the first photosensitive layer 201, the first conductive layer 202, second the 301, second conduction of photosensitive layer with the order of substrate layer 101 from the close-by examples to those far off
Layer 302.
During making, it is necessary first to a substrate layer 101, the material of substrate layer 101 can be glass or plastics, it is flexible and
It is non-flexible；The first photosensitive layer 201 and the first conductive layer 202 are attached on substrate layer 101 by heat pressing process again, the first sense
The conductive layer 202 of photosphere 201 and first has been integrated with together before hot pressing.After the completion of hot pressing, then pass through exposure imaging work
Skill, the line pattern of the first conductive layer 201 is made, the principle of pattern-making is to etch certain thickness by alkali lye in developing process
The first photosensitive layer 201, the first conductive layer 202 being attached on the first photosensitive layer 201 is natural to be stripped, so as to form line
Road pattern.
For described substrate layer thickness in 0.2mm ~ 3.0mm, form can be small pieces or sheet；Then by heating and pressurizeing
The mode of power presses to the first photosensitive layer on substrate layer.According to the effect of pressing adjust temperature and pressure, it is desirable to photosensitive layer and
Bubble-free between substrate layer, and more than adhesive force 4B.
Placed when making the circuit pattern of conductive layer, on the photosensitive layer with whole face conductive material one it is pre-designed
Egative film, put and carry out single exposure under ultraviolet light, and then developed.In developing process, not by the photosensitive of ultraviolet irradiation
Material can be washed off by alkali lye；Because conductive material is attached on photosensitive material, the conductive material outside circuit pattern
It can be washed off together with photosensitive material.Complete to put after the first conductive layer and the first photosensitive layer to expose again under ultraviolet light, allow
Conductive layer and photosensitive layer are stable.
Reference picture 2, the semifinished part being ready in Fig. 1, the second photosensitive layer 301 is made according still further to the method for making Fig. 1
With the second conductive layer 302.
The circuit pattern of second photosensitive layer needs to expose to be made twice, makes to need to expose the first conductive sandwich circuit pin 203
The energy that is subject to of position be less than land.When exposing for the first time, needed in the surface of position of the first conductive sandwich circuit pin 203
A diaphragm is covered, needs to remove diaphragm when exposing for the second time；Double exposure is continuous, the mask bottom of exposure
Piece is different.Developed after second layer exposure, simultaneously can be made the circuit of the second conductive layer, while the circuit pin of first layer
It can expose.The parameter of exposure imaging adjusts according to circuit effect, it is desirable to line clear, no short circuit, breaking phenomena.
After the making for completing two layers of photosensitive layer and conductive layer, in each conductive sandwich circuit Pin locations hot pressing FPC
401, so as to form a complete touch screen products.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to
This, any those skilled in the art in field of the present utility model, all cover in this practicality newly by the change or modification made
Among the protection domain of type.
