An integrated capacitive touch screen connection structure comprises a sensor part and a connection part, wherein the connection part is connected with a main board; and the sensor part and the connection part of the capacitive touch screen are arranged as an integrated structure on a flexible substrate. Connection between the capacitive touch screen and the main board is not realized through a flexible circuit board again, but realized by directly printing conductive substance carbon paste on the flexible substrate which is made of touch sensing unit material, so that process of pre-pressing and pressing FPC (Flexible Printed Circuit) are omitted and cost of FPC is saved; and manufacture processes and comprehensive yield are simplified and improved, so that price of the capacitive touch screen is reduced.
Description
Technical field
The utility model relates to a kind of new structure of capacitance touch screen, belongs to the technical field of capacitive touch screen.
Background technology
Along with popularizing of computer technology, in early 1990s, there is a kind of new human computer interaction's technology-touch screen technology.Utilize the user of this technology as long as just can realize host service function with icon or word that finger touches on computer display lightly, broken away from like this keyboard and mouse action, make man-machine interaction more simple and direct.Therefore, touch screen technology has become the easiest current man-machine communication output device.It has given multimedia with brand-new looks, is extremely attractive brand-new multimedia interactive equipment.
Along with the products such as apple IPhone, iPad Touch pull the brute force of touch-screen, touch-screen has become the industry of several hundred million ten dollars, is in highly growth, estimates within 2016, to grow to 14,000,000,000 dollars, and a year multiple growth rate reaches 18%.The consumption sum of capacitive touch screen will account for main share in various touch-screens.Therefore, only have the price of continuous reduction capacitive touch screen, could keep the sustained competitiveness of product on market.
At present capacitive touch screen is generally used tin indium oxide (ITO) and tempered glass as touch sensing unit and cover plate, simultaneously, use flexible PCB to realize being connected of TP and mainboard, in manufacturing process, first need on FPC, press in advance ACF conducting resinl, and then carry out and this pressure process of base material, this production process is more complicated.
Utility model content
The utility model provides a kind of new structure of capacitive touch screen, and the production process of capacitance plate is simplified greatly, has improved the cost that reduces capacitive touch screen when making yield.
The utility model is adopted following technical scheme by its technical matters of solution:
Integral type capacitive touch screen syndeton, comprises Sensor section, coupling part, and described coupling part is connected with mainboard, it is characterized in that, on flexible parent metal, the sensor part and coupling part is made of one to formula structure.
The beneficial effects of the utility model are as follows:
The utility model capacitive touch screen was realized by flexible PCB with being connected no longer of mainboard, directly on the flexible parent metal of touch sensing unit material, printing conductive material carbon is starched to realize and being connected of mainboard, can save like this precompressed of FPC and the cost of this pressure process and FPC, make production process and comprehensive yield be simplified and promote, thereby reduced the price of capacitive touch screen.
The conductive materials such as the preferred creative use Nano Silver of the utility model capacitive touch screen, Graphene, metal mesh, can reduce the cost of raw material of capacitive touch screen like this, avoid indium rise in price and cause the rise of capacitive touch screen price; Utilize the feature that this type of material pliability is good simultaneously, be convenient to the bending of junction.
The cover plate of this touch-screen, except adopting tempered glass, can also be used the materials such as PMMA, PC composite plate; Can reduce the cost of capacitive touch screen.
The use occasion of the utility model capacitive touch screen can be on the electronic products such as mobile phone, flat board, notebook, desktop computer, game machine, navigating instrument, has expanded the use occasion of capacitive touch screen, has improved the synthesized competitiveness of product.
Accompanying drawing explanation
Fig. 1 is the structure diagram of conventional condenser touch-screen.
Fig. 2 is the structure diagram of the utility model capacitive touch screen.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
Fig. 1 is the structure of existing conventional condenser touch-screen, comprises Sensor section, and Sensor section needs flexible PCB to realize with being connected of mainboard.
The utility model integral type capacitive touch screen syndeton as shown in Figure 2, comprise Sensor section, on described Sensor section, by a junction, divide with mainboard and be connected, on flexible parent metal, the Sensor section of above-mentioned capacitive touch screen and coupling part are made of one to formula structure.
The method for making of the utility model integral type capacitive touch screen syndeton, comprises following step:
The first step, according to touch-control scheme and the structure selected, carry out the layout design of capacitance plate Sensor section;
Second step, the drawing designing according to the first step, at first sputter layer of transparent conductive layer of flexible parent metal;
The 3rd step, by printing etch process, produce the tactility apparatus of capacitive touch screen and peripheral contact conductor simultaneously, herein because the face resistance value ratio of Nano Silver and Graphene is lower and the good feature of pliability, directly adopt Nano Silver, Graphene is as peripheral lead-in wire;
The 4th step, on described coupling part, print the anti-oxidation conductive materials of one deck again, thereby complete the making of Sensor section and coupling part;
The 5th step, at described Sensor section upper surface, cover OCA optical cement;
The 6th step, the cover plate of fitting on the Sensor section that is covered with OCA optical cement, finally carry out deaeration and test, thereby complete the making of whole capacitive touch screen.
Preferably, the material that described transparency conducting layer is used is for a kind of arbitrarily in Nano Silver, Graphene and metal mesh three.
Further, the conductive materials in described the 4th step is carbon slurry.
Preferably, the one that the material that described cover plate is used is tempered glass, PMMA, PC composite plate any materials.
The utility model integral type capacitive touch screen syndeton, makes all-in-one-piece structure by inductive layer and coupling part; Compared with traditional technique, capacitive touch screen of the present utility model has also obtained simplifying greatly at production process, has improved when making yield and can be reduced in cost of manufacture, and the competitiveness of product in market is promoted; Meanwhile, because the material using is beneficial to bending, therefore the capacitive touch screen of this utility model is highly suitable for, on the electronic products such as mobile phone, flat board, notebook, desktop computer, game machine, navigating instrument, having expanded the use occasion of capacitive touch screen.
