Embodiment 1
As shown in Figure 1, a kind of metal grill In-cell touch display screen provided in this embodiment comprising from top to bottom
It sets gradually: glass cover-plate 1, optical cement 2, upper polaroid 3, upper glass plates 4, colored filter (not shown) and black square
Battle array the 5, first metal grill 6, insulating layer 7, the second metal grill 8, protective layer 9, liquid crystal layer (not shown), lower glass plate
10, down polaroid 11；Wherein: black matrix 5 be laterally, it is longitudinal interlaced, first metal grill 6 is formed in described black
For matrix 5 towards in the transverse direction of liquid crystal layer side, second metal grill 8 is formed in the black matrix 5 towards liquid crystal layer side
Longitudinal direction on, the first metal layer is through 8 mutually insulated of insulating layer 7 and the second metal grill.
It designs using the above structure, double layer of metal grid 6,8 is respectively formed at the horizontal and vertical lower section of black matrix 5,
Since metal grill 6,8 is blocked by black matrix 5 invisible completely, the Moire fringe of metal grill and low shadow etc. on the market are overcome
Problem；Furthermore the resistance of metal grill and unconventional strip shaped electric poles, metal grill is significantly lower than strip shaped electric poles, realize more preferable
Touch effect.
First metal grill 6 and the second metal grill 8 can have identical material, and identical line width designs, but
It is not limited to this.
It is further improved, the touch screen further includes that the backlight positioned at 11 lower section of down polaroid (is not shown in figure
Show), one layer of APF film (not shown) is also set up between the down polaroid 11 and backlight.APF film is multilayer film reflection
Type polaroid, the backlight utilization ratio of touch display screen can be improved 30% or more by one side, to make full use of backlight energy
Source, energy saving extend equipment cruise duration；On the other hand, the color offset phenomenon under big viewing angles can be improved, thus right
There is good action in the display effect for improving touch display screen.
It is further improved, as shown in Fig. 2, the insulating layer and protective layer and black matrix correspond, i.e., the described insulation
Layer 12 is lateral strip, is covered in the transverse direction of the black matrix；The protective layer 13 is longitudinal strip, is covered on described
On the longitudinal direction of black matrix.The insulating layer 12 and protective layer 13 are the Bragg reflection structure of insulation, specifically, described exhausted
The Bragg reflection structure of edge is Si3N4And SiO2Alternating forms or silica (SiO2) and titanium oxide (TiOx) alternately form.By
It is high in the reflectivity of Bragg reflection structure, the backlight for being incident on its surface can be reflexed to other directions, wear backlight directly
It crosses colored filter to be utilized or can finally be re-used by multiple reflections or refraction, backlight is avoided to reach black matrix
The problem of reducing backlight utilization ratio, is absorbed by black matrix afterwards, improves the display brightness of In-cell touch screen.
It is highly preferred that as shown in figure 3, the cross section of the insulating layer 12 and protective layer 13 be it is trapezoidal, i.e., close to described black
The side width of matrix 5 is wider than the side width far from the black matrix 5, and the backlight for being incident on trapezoidal different zones will be reflected
To different directions, for example, light A ' is incident on the trapezoidal region parallel with glass plate, to lower glass plate (array base after being reflected
Plate) direction propagation, which passes through multiple reflections or refraction is finally re-used；Light B ' is incident on trapezoidal and glass
The region that glass plate tilts is propagated after being reflected to the direction of colored filter, is then directly projected.
As the alternate embodiments of the present embodiment, the glass cover-plate could alternatively be plastic cement composite plate cover board, plastic cement
Composite decking is easy molding, and the fraction defective in production process is low, and has excellent toughness and impact resistance.
It should be noted that the lower glass substrate is array substrate.The black matrix material is preferred but is not limited to black
Color organic resin material.
It should be noted that the patterning schemes of first metal grill and the second metal grill press capacitance touch structure
It designs, i.e., described first metal grill is the first touch function layer, for incuding touch point in the position of X-direction；It is described
Second metal grill is second touch control electrode, for incuding touch point in the position of Y direction.First metal grill and
Two metal grills are connected separately with external electrode, wherein external electrode, that is, golden finger, the transmission for signal.
Wherein, the material of first metal grill and the second metal grill be Cu, Ag, Al, Ti or Ni at least
It is a kind of.Wherein, the grid pattern of first metal grill and the second metal grill is rectangle, square, diamond shape, hexagon
Or other polygons.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, but those skilled in the art answer
Work as understanding: it is still possible to modify the technical solutions described in the foregoing embodiments, either to part of or complete
Portion's technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical
The range of novel each embodiment technical solution.
