Description
Technical field
This application involves technical field of touch control, more particularly to conductive film and gold based on metal grill (Metal-Mesh)
Belong to grid touch sensor.
Background technology
Conductive film is that not only have high conductivity, but also have good translucency, is with a wide range of applications.In recent years
Through the transparent electrode transparent surface heater for being successfully applied in liquid crystal display, touch panel, electromagnetic wave proof, solar cell
And in the fields such as luminescent device.
In touch screen technical field, sensing element of the transparent conductive film usually as input signals such as induction touches.One
As, transparent conductive film includes transparent substrates and the conductive layer in transparent substrates.Currently, tin indium oxide (Indium Tin
Oxides, ITO) be conductive layer in transparent conductive film main material.
However, indium is a kind of metal material of costliness, therefore the material using ITO as conductive layer is largely promoted
The cost of touch screen.In addition, ITO conductive layer is in patterning process, need to the positive ito film good to plated film be etched, with
ITO pattern is formed, not only complex process, but also in this process, a large amount of ito film is etched, your a large amount of gold caused
Belong to waste and pollution.
Therefore, in the ascendant in the leading one chip glass touch technology solutions of OGS, touch technology of new generation
It Metal-Mesh-Sensor (metal grill/metalolic network sensor) and quietly shapes.
From the point of view of the current market structure, in recent years, due to lacking new technology and new material, domestic touch-control market is always
It is monopolized by the first, second generation touch-control product such as infrared, resistance, projecting type capacitor, optical panel.And it starts to walk relatively late
Metal-Mesh touch technologies then by offshore company's technical monopoly, stagnate because of import price height.What is Metal-
Mesh-SensorMetal-Mesh-Sensor is that a kind of metal fine gathers the touch-control sensing formed on by PET base material
Device.

The conductive thread of intersection is formed by the grid of regular shape, and for example, lattice shown in FIG. 1 can be square, into one
Step ground, diamond shape and hexagon are also feasible；Conductive film will appear more significantly not when being attached at liquid crystal display surface
That fringe phenomena, so as to cause the visual discomfort sense of user.Moire fringe is between two lines or two objects with constant
The visual effect that angle peace rate interferes can only see interference when human eye can not differentiate this two lines or two objects
Decorative pattern, seriously affect visual effect.
Currently, in the grid pattern of Metal-Mesh, mostly come by adjusting the angle, the length of side and direction on diamond shape side
Change the spatial frequency of Moire fringe, as shown in Figures 2 and 3.Although this lattice has reached the mesh of reduction Moire fringe
, however in the pattern described in Fig. 2 or Fig. 3, because there are various parallel lines, all directions are likely to can have More's item
Line.Thus, this lattice also is difficult to ensure effectively weaken Moire fringe in each direction.
