As on this area, technician is known, touch control line need connect through flexible circuit board (FPC), so in the present invention, described polarisation inductive component also comprises flexible circuit board, and described flexible circuit board is fixedly electrically connected to described conductive layer.
Present invention also offers the preparation method of above-mentioned polarisation inductive component, it is characterized in that, comprising:
Under S1, normal temperature, form conducting film on polaroid surface;
At S2,30-50 DEG C, form photosensitive glue-line on conducting film surface;

According to the present invention, first, as step S1, form conducting film on polaroid surface, make conducting film cover polaroid surface.Because polaroid is the vitals that LCD assembly realizes Presentation Function, the deterioration of polaroid and distortion directly can affect display effect.And usually, polaroid heat resistance is poor.Prepare insulation course (solidification) when the method (such as high temperature plating ITO transparency conducting layer) of conventional making conducting film and gap bridge connection all to need to carry out at relatively high temperatures, very easily cause deterioration and the distortion of polaroid.
In the present invention, when preparing above-mentioned conducting film, need make at normal temperatures.Concrete, the method making conducting film under above-mentioned normal temperature can adopt existing various method, such as, can for normal temperature plating tin indium oxide, be coated with nanometer silver paste and normal temperature cure, carbon nanotubes slurry normal temperature cure.The concrete technology step of above-mentioned various making conducting film itself can adopt existing, repeats no more in the present invention.Can form conducting film on polaroid surface by above-mentioned various method, the material of the conducting film of above-mentioned formation is specifically as follows the one in indium oxide tin film, nanometer silverskin, carbon nano-tube film.
According to the present invention, for ensureing the stable of the final conductive layer formed, avoid manufacturing process to the damage of polaroid, under preferable case, the thickness of the conductive layer prepared on polaroid surface is 10-50nm simultaneously.

As described in step S6, employing concentration is that the curing area of sodium hydroxide solution to described photosensitive glue-line of 0.2-0.5mol/L processes, removed the curing area of photosensitive glue-line, form conductive layer, described conductive layer pattern is the individual layer multiple spot conductive pattern of single-ended outlet or two induction pattern.
After preparing above-mentioned conductive layer, flexible circuit board can be fixedly electrically connected to this conductive layer by those skilled in the art.Concrete grammar can adopt existing, such as, by conductive hot melt glue, flexible circuit board is tied to conductive layer.
Polarisation inductive component provided by the invention can be obtained by said method.By said method, by preparation, there is the individual layer multiple spot conductive pattern of single-ended outlet or the conductive layer of two induction pattern, carrying out gap bridge connection without the need to making insulation course, can preparation technology be simplified, the damage carrying out passing a bridge to polaroid when connecting can be avoided simultaneously; On the other hand, said method carries out all at normal temperatures, can not produce damage, be beneficial to guarantee yield to polaroid.Finally, effectively touch control line can be combined with polaroid by said method, while Simplified flowsheet, can raw materials cost be reduced, improve and produce yield.
Further, after using for a long time, insulation course is easily oxidized and aging, or under the long-time erosion of comparatively rugged surroundings (raining, high temperature etc.), and decreasing insulating and the occurring not enough touch controllable function caused that insulate is bad.
The present invention effectively can avoid the various bad situation caused because of insulation course, substantially increases the quality of touch control display device.
