Background technology
There are many kinds of conductive film production structures and technique, and mainstream is oxygen indium tin (Indium Tin Oxide, abbreviation at present：
ITO) etch process and sodium rice silver coating process.ITO is divided into glass ITO and film ITO according to the difference of base material, is in glass
Or by splashing or being deposited ITO conductive layer on film, then conductive film made by etch process.This conducting membrane material is of high cost and work
Skill is complicated, and because ito surface resistance value is big, and generally in the Ω of 50 Ω/side~150/side, touch-control sensitivity is poor, and big ruler should not be made by existing
The shortcomings of very little touch screen.Sodium rice silver coating process is that sodium material silver paste is coated on containing on recess mesh film, by low-temperature solid
Change, the technique for forming conductive film.This technique manufacture conductive film can not ensure appearance requirement, and ag material is of high cost, is not suitable for making list
Layer two-sided structure (single-sided conductive layer needs repeatedly coating, wiping, low-temperature setting to complete), difficulty of processing is high, and yield is low.
Traditional One-layer multi-point touch control conductive film is mostly to be set on the same surface of film (FILM) material, such as Fig. 1 institutes
Show, traditional GFF structures of touch screen have a five-layer structure, including protective glass (COVER GLASS), upper glue layer (TOP OCA),
Upper film layer (TOP FILM), intermediate gelatine layer (MID OCA) with metal grill and the lower film layer (BOT with metal grill
FILM).Above structure is more demanding to design, and bridging structure is formed in conductive pattern or more, need in addition print or
Outer plating layer protective layer is filled and led up and is protected, and increases product thickness and production link, leads to traditional one-layer multi-point touch control
The thickness of conductive film is larger, production technology is complex.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of single-layer double-side conductions
Membrane structure, manufacture craft and touch screen.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of single-layer double-side conductive film structure, including a film substrate, the tow sides of the film substrate be all provided with it is fluted,

Further, the metal grill uses reduced copper gauze lattice.
A kind of manufacture craft of single-layer double-side conductive film structure as mentioned, includes the following steps：
1) positive and negative lattice mold is designed；
2) by way of two-sided UV coinings, positive and negative lattice is transferred to one using the positive and negative lattice mold
On film substrate, formed with reeded film substrate；
3) the applying conductive coating on the positive and negative with reeded film substrate；
4) film substrate obtained to step 3) is electroplated, the forming metal grid in the groove.
Further, the film substrate is optical grade flexible film substrates.
Further, the film substrate is PET, PC or PMMA.
Further, the conductive coating includes electrically conductive ink or conductive glue.
Further, it in the step 4), while forming nanoscale in the positive and negative groove of film substrate and restoring layers of copper.
A kind of touch screen, including the protective glass layers, OCA glue-lines and the conductive film layer that set gradually, the conductive film layer are adopted
With single-layer double-side conductive film structure as mentioned.
Compared with prior art, the present invention has the following advantages：
1) present invention realizes a kind of single-layer double-side conductive film structure, simple in structure.
2) present invention positive and negative one-pass molding conductive layer on a FILM material, it is simple for process.
3) present invention selection is resistant to the FILM materials of 130 degree of low temperature below, improves product yield.
4) at present Metal Mesh generally scrape silver process, this technique is that slurry directly blows into FILM materials surface with scraper
In groove, FILM materials surface can be remained in by not blowing into the slurry of groove, and such appearance is difficult to management and control, and the present invention is using plating
The technique for forming nanoscale reduction layers of copper, membrane material appearance are controllable.
5) the conductive film structure prices of raw materials of the present invention are cheap, effectively reduce the cost of touch screen.
6) present invention realizes metal grill using metallic copper, and electric conductivity is excellent, and face resistance value is suitble to do within 5 Ω/side
Large touch screen.
