Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model embodiment provides a kind of touch screen, and touch screen includes touch layer.Touch layer includes metal grill
Pattern layer.Metal grill pattern layer by multiple polygonal mesh with while while connect and form.The metal wire of metal grill pattern exists
It is bulge-structure on substrate layer.Using the grid lines polytropism of polygonal mesh, the bottom shadow effect of touch screen can be reduced and rubbed
That striped.Metal grill has good buckle resistance energy and low resistive energy.The metal grill pattern layer of polygonal mesh
Lattice node it is numerous, even if some lattice node therein disconnects when bending, the pathway electrode of touch layer is not yet
It can directly open circuit.Metal grill is usually that institute's shape is suppressed on substrate layer using the conductive metal materials such as silver, copper or oxide
At conductive metal mesh.
In order to avoid opaque metal grill influences display effect, the line width of metal grill metal wire is very thin, such as
It is 10 μm or less.Cause bad in order to avoid the line of metal grill is easy to disconnect, touch layer further includes ito film layer, ito film layer
For planar film layer and the covering metal grill pattern layer.The all conductive energy of the whole face of ito film layer.Even if such metal
Grid can also conduct the electric current of touch sensible generation in local disconnection by ito film layer, reduce fraction defective.
Ito film layer is to increase by one layer of ITO protection on the basis of metal grill, avoids that single ITO's is crisp not bent, is also increased
Add the bendable folding endurance of metal grill.Because of the buckle resistance energy of metal grill, make it compared with other materials such as list ITO in flexible touch screen
On have greater advantages.
If ITO grid identical with metal grill pattern is made on metal grill, since ITO grid is by right
ITO etching obtains, and will lead to second etch metal grill in ITO etching.Because the line width of metal grill is very thin, ITO erosion
It can be that metal wire disconnection leads to the bad of metal grill to the second etch of metal grill when quarter.
And the ito film layer in the application can not only touch in conduction due to being planar film layer when metal grill locally disconnects
Touch electric current, the reduction fraction defective that induction generates, it can also be ensured that the low resistivity of aisle resistance is conducive to provide the touching of touch screen
Control sensitivity.Meanwhile avoid production ITO grid and caused by the second etch of metal grill.
Preferably, ito film layer thinner thickness, the ito film layer covered on metal grill, that is, be layered on metal wire
Ito film layer, with a thickness of 100 ~ 3000 angstroms.Preferably, metal grill with a thickness of 2000 ~ 5000 angstroms.
In more specific one embodiment, touch layer includes the first touch layer 10 and the second touch layer 30.Such as Fig. 1 and figure
Shown in 2, the first touch layer 10 includes multiple first passage electrodes extended in a first direction.Fig. 1 only schematically illustrates two
A channel electrode, it is to be understood that, the quantity of first passage electrode is without being limited thereto.First passage electrode includes the first metal mesh
Trrellis diagram pattern layer 12 and the first ito film layer 11.First metal grill pattern layer 12 and the conducting of the first ito film layer 11.
Likewise, the second touch layer 30 also includes multiple second channel electrode (not shown) extended in a second direction.The
Two channel electrodes include the second metal grill pattern layer and the second ito film layer.The second metal grill pattern layer and the 2nd ITO
Film layer conducting.
First direction is substantially vertical with second direction, but not limited to this.The area DUMMY is provided between adjacent channel electrode
Domain, it is short-circuit between channel electrode for avoiding.
Ito film layer can partially cover the metal grill pattern, as shown in Figure 1.Or ito film layer can be completely covered
The metal grill pattern, coats metal grill completely by ito film layer.
Touch screen can be flexible touch screen or non-flexible touch screen.
Preferably, touch screen is flexible touch screen.Substrate layer is flexible parent metal.As a preferred option, flexible parent metal is
PET or film Film.
As shown in figure 3, first passage electrode and second channel electrode are the structure of stacking.First metal grill pattern layer
1210 polygon pattern and the wrong arrangement of the polygon pattern of the second metal grill pattern layer 30 submission, more specifically, the first gold medal
Belong to the center of 12 polygon of grid chart pattern layer, the intersection point of the corresponding polygon for being overlapped in the second metal grill pattern layer.
By setting, make the center of 12 polygon of the first metal grill pattern layer, correspondence is overlapped in second metal mesh
The intersection point of the polygon of trrellis diagram pattern layer makes the first metal grill pattern, in being staggered, not only may be used with the second metal grill pattern
To upset the vertical bar gap of the regularly arranged formation of existing metal grill, reduce metal grill touch screen bottom shadow effect and mole
Striped.By the setting of first passage electrode and second channel electrode, it can guarantee that the resistance value in each passage area is identical, driving electricity
Press identical to different touch point driving effects, drive relatively simple, and the induction point on unit area is more, touch performance compared with
It is good.
Polygon can be the regular polygon of irregular polygon or regular shape.Such as irregular triangle,
Quadrangle, pentagon, hexagon etc..Or regular polygon, the number of edges of regular polygon are greater than 4, as regular pentagon, regular hexagon,
Regular heptagon, octagon.
Preferably, polygon is regular polygon.More preferred, polygon is regular hexagon.
First touch layer 10 further includes the first substrate layer 20, and the first substrate layer 20 can be located at the top of first passage electrode
Or lower section.
Second touch layer 30 further includes the second substrate layer, the second substrate layer can be located at second channel electrode top or
Lower section.
As a specific embodiment, for example: the first substrate layer 20 is located at the lower section of first passage electrode.It can
The metal grill pattern of polygon is made on the first substrate layer 20 with elder generation, forms the first metal grill pattern layer 12.It is making
Whole face plating ITO makes first passage electrode after metal grill pattern.
Compared with the existing technology, the beneficial effects of the utility model are as follows:
Using the grid lines polytropism of polygonal mesh, the bottom shadow effect and Morie fringe of touch screen can be reduced.It is polygon
The lattice node of the metal grill pattern layer of shape grid is numerous, even if some lattice node therein is disconnected when bending
It opens, the pathway electrode of touch layer will not directly open circuit.The all conductive energy of the whole face of ito film layer.Even if metal grill exists
Part disconnects, and the electric current of touch sensible generation can also be conducted by ito film layer, reduces fraction defective.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
All these improvement or transformation all should belong within the protection scope of the appended claims for the utility model.
