Description
Technical field
The utility model is related to capacitance type touch control screen technical field, more particularly to a kind of transparent conducting film and touch-control
Screen.
Background technology
Transparent conducting film is the core element of capacitance type touch control screen.With the rapid development of intelligent terminal, to transparent
The demand of conductive membrane is also increasingly to increase.Transparent conducting film generally comprises base material and is set to the hard of base material both sides
Coating, conductive layer and metal layer.Currently, since amorphism thin polymer film is compared with crystalline polymer film, have two-fold
Penetrate the less and uniform advantage of rate, therefore the base material that most of transparent conductive film is formed using armorphous polymer thin film.
Amorphism thin polymer film is more fragile than crystalline polymer film, and surface is easier to be damaged.It is crimping
Transparent conducting film make its be tubular when, the metal layer that can have adjacent transparent conductive film generates adhesion and crimping each other
The problem of.Therefore, occur adding particle in hard conating, so that layer on surface of metal forms the transparent conducting film of protrusion.
Protrusion can make adjacent metal layer form point contact, to avoid sticking together and crimp.
However, protrusion can make the surface of hard conating have difference in height, so that the surface roughness of hard conating increases.This
Sample can influence the crystallinity of conductive layer, cause its sheet resistance uneven, so that conductive film is poor quality
Utility model content
Based on this, it is necessary to the uneven, inferior quality for the existing transparent conductivity sheet resistance with resist blocking and that function
The problem of, a kind of transparent conducting film and touch screen that can effectively promote quality is provided.
A kind of transparent conducting film, including：
Base material, including the first surface and second surface that are oppositely arranged；
It is sequentially formed in the first hard conating, the first transparency conducting layer and the first metal layer of the first surface；
It is sequentially formed in the second hard conating, the second transparency conducting layer and second metal layer of the second surface；
First hard conating contains multiple particles, described to form multiple protrusions on the surface of the first metal layer
The ranging from 0.25um of the height Rz of multiple protrusions<Rz<0.5μm.
Due to the presence of protrusion so that transparent conducting film has the function of resist blocking and that.Moreover, the height Rz of protrusion
Ranging from 0.25um<Rz<0.5μm.Compared with traditional conductive film, protrusion is highly effective while meeting resist blocking and that demand
Reduce, therefore the difference in height between protrusion also reduces therewith, so that the roughness of hard coating surface reduces.Further, shape
Crystallinity at the conductive layer in hard coating surface is improved, so that sheet resistance is uniform.Moreover, because the only first hard painting

It states.
In addition, the first hard conating 12 contains multiple particles 15, to form multiple raised 16 on the surface of the first metal layer 14.
Moreover, the ranging from 0.25um of multiple raised 16 height Rz<Rz<0.5μm.Therefore, there is leading for resist blocking and that function with existing
Electrolemma is compared, and the highly significant of 10 protrusions 16 of transparent conducting film reduces.Wherein, the height of protrusion 16, refers to protrusion
16 protrude from the height on 14 surface of the first metal layer.
It should be pointed out that since 15 size of particle is smaller, therefore be difficult to accurately control each raised 16 height
System.Therefore, the height of protrusion 16 is controlled in above-mentioned altitude range.Further, in actual production, due to being difficult to
The height for having few partial particulate 15 and being formed by protrusion 16 that the progress of each particle 15 is accurately controlled, therefore is difficult to avoid that
Degree is located at outside above range.But it is influenced caused by part protrusion 16 negligible.In addition, what height Rz also can refer to
It is the average value of a certain number of raised 16 height in preset range.
Specifically, particle 15 can irregularly, can also preset rules (as equably) be distributed in the first hard conating 12
It is interior.Particle 15 can be spheric granules or the particle of other shapes.
Particle 15 is only contained in the first hard conating 12, to obtain the transparent conducting film that single side is formed with protrusion 16
10.Wherein, the process that protrusion 16 is formed by particle 15 is specific as follows：
Particle 15 protrudes from the surface of the first hard conating 12, to make the surface of the first hard conating 12 form the area of evagination
Domain, and the region that the first hard conating 12 is not provided with particle 15 then forms flat site 17.Due to the first transparency conducting layer 13 and
One metal layer 14 is cascading the surface with the first hard conating 12, therefore the table of the surface shape of the two and the first hard conating 12
Face shape is identical.Therefore, in the region corresponding with particle 14 of the first metal layer 14, multiple raised 16 can be formed.
When using transparent conductive film 10 of the roll-to-roll process (roll to roll process) to manufacture strip, by
The surface of the first metal layer 14 is set to form multiple raised 16 in particle 15.Therefore, multiple when crimping transparent conducting film 10
Protrusion 16 can make to form point contact between two neighboring metal layer, to prevent its stick to each other, crimping.
Moreover, the ranging from 0.25um of the height Rz of protrusion 16<Rz<0.5μm.Compared with traditional conductive film, meeting
The height of protrusion 16 reduces while resist blocking and that demand, therefore the difference in height between protrusion 16 also reduces therewith, so that hard apply
The roughness of layer surface reduces.Further, being formed in the crystallinity of the conductive layer of hard coating surface is improved, so that
Sheet resistance is uniform.Moreover, because contain particle in only the first hard conating 12, therefore the roughness on 22 surface of the second hard conating is further
It reduces.Therefore, the quality of transparent conducting film 10 is effectively promoted.
Further, since the roughness of hard coating surface reduces, therefore the flatness for the conductive layer and metal layer being subsequently formed
Increase, to which the cracking resistance of transparent conducting film 10 can also be promoted.
In the present embodiment, particle 15 is identical as the material of the first hard conating 12.
Since particle 15 is identical as the material of the first hard conating, therefore its optical parameter is also identical.Therefore, in particle 15 and
The linkage interface of one hard conating 12, light propagation institute is impacted smaller, and particle 15 and the first hard conating 12 are closer whole for one
Body.When light passes through the first hard conating 12 containing particle 15, the distortion that round generates is smaller.Therefore, transparent to lead
Electric thin film 10 is achieving the purpose that resist blocking and that, resistance to compression connect simultaneously, moreover it is possible to its optical property be avoided to be adversely affected.
Further, in the present embodiment, the material of particle 15 is silica, organosilicon polymer, acrylic polymer
Close object or styrene polymer.
The above material has the advantage that translucency is good, is easily obtained, can be in the premise for meeting performance requirement for particle 15
Decline low cost.Certainly, also other suitable materials can be selected according to actual performance and cost needs.
In the present embodiment, the distribution density of protrusion 16 is 100~3000/mm2。
When the distribution density of protrusion 16 is excessive, it can lead to that the haze value of transparent conducting film 10 is excessive, light transmission rate drop
It is low, and then seriously affect the appearance and optical effect of transparent conducting film 10.And if the distribution density of protrusion 16 is too small,
The effect of resist blocking and that is limited.In above-mentioned density range, transparent conducting film 10 can preferably take into account resist blocking and that and optics effect
Fruit.
Fig. 2 and Fig. 3 is please referred to, in the utility model another embodiment, particle 15 is elongated, and particle 15 is hanging down
Directly it is more than the size on being parallel to the direction of first surface in the size on the direction of first surface.
Traditional particle is spherical in shape or unsetting, laterally (being parallel to substrate surface) and longitudinal (perpendicular to base material table
Face) size is suitable.Therefore, when needing to increase raised 16 height, longitudinal and transverse direction size is both needed to equal proportion increase.However,
When the lateral dimension of particle 15 is excessive, the interception caused by particle 15 is more apparent, so as to cause the mist degree of conductive film
Increase.
And it is elongated by particle 15 in this present embodiment, when particle 15 is vertical or is approximately perpendicular to first surface setting
When, the size of (longitudinal direction) on the direction perpendicular to first surface of particle 15 is more than on being parallel to the direction of first surface (horizontal
To) size.That is, particle is longitudinal bigger with lateral size.Therefore, even if the height of protrusion 16 increases, particle
15 lateral dimension can still be maintained to a lesser extent, to promote the same of 10 resist blocking and that effect of transparent conducting film
When, moreover it is possible to effectively reduce its mist degree.

Prefabricated improved efficiency, and then promote the preparation efficiency of transparent conducting film 10 and reduce cost.
In another embodiment, there are gaps between multiple particles 15 and the surface of base material 11.
Therefore, particle 15, which is equivalent to, is suspended in the first hard conating 12, is not in direct contact with base material 11.Existing anti-
In the conductive film of adhesion, the grain size of particle must be more than the thickness of hard conating, otherwise can not form protrusion on the surface of metal layer.Cause
This, the particle size of particle is limited to the thickness of hard conating, can not further reduce.
In the present embodiment, since particle 15 is suspended in the first hard conating 12.Therefore, even if the grain size of particle 15 is less than
The thickness of hard conating nor affects on it and forms protrusion 16 on the surface of the first metal layer 14.That is, the grain size of particle 15 is not
It being limited by hard coat layer thickness, the grain size of suspended particulate 15 can further reduce, to reduce haze value, promote light transmission rate,
It is final to improve optical effect.
In order to realize that more preferably resist blocking and that and resistance to compression connect effect, for the table of the first metal layer 14 and second metal layer 24
The dense degree of face protrusion 16 has corresponding requirement.
Above-mentioned transparent conducting film 10, due to the presence of protrusion 16 so that transparent conducting film 10 has resist blocking and that
Function.Moreover, the ranging from 0.25um of the height Rz of protrusion 16<Rz<0.5μm.It is anti-meeting compared with traditional conductive film
The height of protrusion 16 reduces while adhesion demand, therefore the difference in height between protrusion 16 also reduces therewith, so that hard conating
The roughness on surface reduces.Further, being formed in the crystallinity of the conductive layer of hard coating surface is improved, so that side
Resistance is uniform.Moreover, because contain particle in only the first hard conating 12, therefore the roughness on 22 surface of the second hard conating further drops
It is low.Therefore, the quality of above-mentioned transparent conducting film 10 is effectively promoted.
