In touch-screen field, form touch control electrode usually just like under type:
(1) directly in substrate, conductive layer is formed.Be example with ITO (Indium Tin Oxide, tin indium oxide) conductive layer, need first to carry out ITO plated film, then graphical treatment is carried out to the ITO layer obtained, to obtain touch control electrode.Because touch control electrode is outside exposed, be easily scratched, and then cause the electric conductivity of touch control electrode to reduce.
(2) transparent matrix layer is set in substrate, then adopt the modes such as impression on transparent matrix layer, form latticed groove, in latticed groove, filled conductive material is (such as again, metal, Graphene etc.), form latticed conductive layer, latticed conductive layer comprises the touch control electrode of many mutually insulateds.Because the side of touch control electrode is exposed to outside transparent matrix layer, and the easily oxidation by air of a lot of conductive materials (such as, argent).And the oxidized meeting of conductive material causes the electric conductivity of touch control electrode to reduce.
For solving the problem, in the present embodiment, in the following way:
As shown in Figure 5, transparency conducting layer 18 comprises matrix 181 and is filled in the electrical-conductive nanometer silk thread 182 in matrix 181.This matrix 181 is the transparent feel photopolymer resin of solidification.
In the present embodiment, the interlaced overlap joint of electrical-conductive nanometer silk thread 182 and being uniformly distributed in matrix 181 entire scope, makes the overall homogeneous conductive of transparency conducting layer 18.Also be, transparency conducting layer 18 comprises many spaced matrix bands, there is barish substrate in the interval between adjacent two matrix bands, this substrate is second substrate 17 (as shown in Figure 1) or is upper polaroid 19 (as in Figure 2-4).In each matrix band entire scope, the staggered overlap joint of equally distributed many electrical-conductive nanometer silk threads 182 forms each touch control electrode.Partially conductive nanometer silk thread 182 exposes the surface of matrix 181 second substrate 17 dorsad, makes this surface conduction, thus is convenient to be connected with perimeter circuit and spread out of touching signals.Consider that can the adhesion of transparency conducting layer 18 and electrical-conductive nanometer silk thread 182 preferably in filling substrate 181, the thickness of transparency conducting layer 18 is preferably 0.1 μm ~ 50 μm.
The diameter range of electrical-conductive nanometer silk thread 182 can be 10nm ~ 1000nm, and the length range of electrical-conductive nanometer silk thread 182 can be 0.02 μm ~ 50 μm, and the diameter of electrical-conductive nanometer silk thread 182 is less than the visual width of living human eye, thus ensures visually-clear.Electrical-conductive nanometer silk thread 182 can be easy to prepare for gold nanowires line, silver nanoparticle silk thread, Cu nanowire line, aluminium nanometer silk thread, carbon nanometer silk thread etc. and have the conductive thread of better electric conductivity.In the present embodiment, comprehensive electric conductivity and cost, electrical-conductive nanometer silk thread 182 adopts silver nanoparticle silk thread.
The square Standard resistance range of transparency conducting layer 18 can be 0.1 Ω/ ~ 500 Ω/.Compared to ITO conductive layer, there is better electric conductivity, being more suitable for for making as panel computer (pad), all-in-one (All in one, AIO), touch-control product that notebook (Notebook) equidimension is larger.
The electric conductivity of transparency conducting layer 18 is relevant to the diameter of electrical-conductive nanometer silk thread 182 and electrical-conductive nanometer silk thread 182 distribution density, and diameter is larger, and distribution density is larger, then electric conductivity is better, and namely sheet resistance is lower.But the diameter of electrical-conductive nanometer silk thread 182 is larger, distribution density is larger, the transmitance of transparency conducting layer 18 is lower.Therefore, in order to ensure the balance of transmitance and electric conductivity, the sheet resistance of transparency conducting layer 18 is preferably 50 Ω/ ~ 200 Ω/.
As shown in Figure 6, in other embodiments, electrical-conductive nanometer silk thread 184 is uniformly distributed in the region of matrix 183 wherein side certain limit dorsad, and do not have electrical-conductive nanometer silk thread 184 to distribute in the region of the relative opposite side certain limit of matrix 183, make transparency conducting layer 18 form nonconductive regions 185 and conduction region 186 in a thickness direction.When transparency conducting layer 18 is arranged on second substrate 17 surface, the nonconductive regions 185 of transparency conducting layer 18 adjoins second substrate 17.And when transparency conducting layer 18 is arranged on upper polaroid 19 surface, the adjacent upper polaroid 19 of nonconductive regions 185 of transparency conducting layer 18.
Further, the thickness of nonconductive regions 185 is greater than the thickness of conduction region 186, and the thickness of nonconductive regions 185 is 0.5 μm ~ 50 μm, and the thickness of conduction region 186 is 0.01 μm ~ 1 μm.Because one of the effect of nonconductive regions 185 is the adhesive strengths that improve transparency conducting layer 18, thus the thickness that reduce conduction region 186 under transparency conducting layer 18 has the prerequisite of good electric conductivity as far as possible can ensured.Owing to only needing to carry out patterning (formation touch control electrode) to conduction region 186 during transparency conducting layer 18 patterning, the thickness of conduction region 186 reduces to contribute to reduce the difference in height of drafting department and background portion after patterning, avoids the outward appearance that easily caused by identification due to pattern not good.
