Description
Technical field
The utility model relates to touch field more particularly to a kind of metal grill touch screen.
Background technique
As shown in Figure 1, existing metal grill touch screen has two layers of OC glue, wherein the first OC glue is located at the first metal
Between layer and second metal layer, main function is that the peripheral leads of the first metal layer are protected and be dielectrically separated from the first gold medal
Belong to layer and second metal layer, and the 2nd OC glue is located in second metal layer, main function is drawn to the periphery in second metal layer
Line is protected.Due to needing two layers of OC glue, existing metal grill touch screen has twice OC technique, and processing step is more,
And step is more, then yields is lower.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of metal grill touch screen, which reduce
One of OC technique, yields are higher.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of metal grill touch screen, including transparent substrate and the first metal being sequentially laminated on the transparent substrate
Layer, transparent insulating layer and second metal layer；The first metal layer includes the first metal grill and position on visible area
In the first peripheral leads and the second peripheral leads in peripheral region, first peripheral leads draw first metal grill
To the binding region of side；The second metal layer includes the second metal grill on the visible area, outside described second
Lead is enclosed to lead to second metal grill in the binding region of side by the overlap joint slot on the transparent insulating layer.
Further, the transparent insulating layer has at least one overlap joint slot, and the overlap joint slot is correspondingly arranged at described
On lap position between second peripheral leads and the second metal grill.
Further, the transparent insulating layer avoids the binding region.
Further, the peripheral region of the transparent insulating layer is towards being provided with anti-lid in the one side of the second metal layer
Ink, the anti-lid ink avoid the binding region.
Further, the transparent substrate is terminal cover board, and peripheral region is towards in the one side of the first metal layer
It is provided with frame ink, first peripheral leads and the second peripheral leads are arranged on the frame ink.
Further, the transparent substrate is rigid substrate or fexible film.
Further, a protective film is fitted in the second metal layer.
Further, the protective film is rupture pressure disc.
Further, the transparent insulating layer is OC glue or inorganic non-metallic sull.
The utility model has the following beneficial effects: the metal grill touch screen is etching the first metal layer to make
When first metal grill and the first peripheral leads, the second peripheral leads for being connected to the second metal layer make together, so
Remain for overlapping the overlap joint slot of second metal grill and the second peripheral leads in advance when making the transparent insulating layer afterwards,
Second metal grill can be only made when etching the second metal layer in this way, and since the second metal layer does not have
There are peripheral leads, no longer need to covering second layer transparent insulating layer, reduce the manufacture craft (OC technique) of one of transparent insulating layer,
Yields is higher.
Detailed description of the invention
Fig. 1 is the stacking schematic diagram of existing metal grill touch screen；
Fig. 2 is the stacking schematic diagram of metal grill touch screen provided by the utility model；
Fig. 3 is the schematic diagram of the first metal layer of metal grill touch screen shown in Fig. 2；
Fig. 4 is the schematic diagram of the second metal layer of metal grill touch screen shown in Fig. 2；
Fig. 5 is the schematic diagram of the transparent insulating layer of metal grill touch screen shown in Fig. 2.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Fig. 2, a kind of metal grill touch screen, including transparent substrate and is sequentially laminated on the transparent substrate
The first metal layer, transparent insulating layer 3 and second metal layer；As shown in figure 3, the first metal layer includes being located on visible area
The first metal grill 11 and the first peripheral leads 121 and the second peripheral leads 122 in peripheral region, outside described first
Lead 121 is enclosed to lead to first metal grill 11 in the binding region of side；As shown in figure 4, the second metal layer packet
The second metal grill 21 being located on visible area is included, second peripheral leads 122 pass through taking on the transparent insulating layer 3
Access slot hole 31 leads to second metal grill 21 in the binding region of side.
The metal grill touch screen is etching the first metal layer to make outside first metal grill 11 and first
When enclosing lead 121, the second peripheral leads 122 for being connected to the second metal layer make together, then described transparent exhausted in production
The overlap joint slot 31 for remaining for overlapping second metal grill 21 and the second peripheral leads 122 when edge layer 3 in advance, is etching in this way
It can only make second metal grill 21 when the second metal layer, and since the second metal layer is drawn without periphery
Line no longer needs to cover another transparent insulating layer, reduces one of transparent insulation technique (OC technique), yields is higher.
First metal grill 21 forms a plurality of first sense wire for sensing the touch location on first direction, institute
It states the second metal grill 22 and forms a plurality of second sense wire for sensing the touch location in second direction, first sensing
It is interlaced between line and the second sense wire.
As shown in figure 5, the transparent insulating layer 3 has at least one overlap joint slot 31, the overlap joint slot 31 is correspondingly arranged
On lap position between second peripheral leads 122 and the second metal grill 21.
The transparent insulating layer 3 is preferably but not limited to as OC glue, or the inorganic non-metallics oxygen such as silica membrane
Compound film is engraved structure on the position for corresponding to the binding region, to avoid the binding region；It is described transparent
The peripheral region of insulating layer 3 is towards anti-lid ink is provided in the one side of the second metal layer, and the anti-lid ink is in correspondence
In being also engraved structure on the position of the binding region, to avoid the binding region；The color of the anti-lid ink is preferred
First peripheral leads are reduced for black to carry out shading to first peripheral leads 121 and the second peripheral leads 122
121 and second peripheral leads 122 to the volume reflection of light.
The transparent substrate can be terminal device terminal cover board, peripheral region towards the first metal layer one
Frame ink is provided on face, first peripheral leads 121 and the second peripheral leads 122 are arranged on the frame ink,
The first metal layer and second metal layer are directly produced on the terminal cover board, to form OGM(On Glass Metal)
Structure；The transparent substrate may be the rigid substrates such as the glass substrate of Rimless ink, plastic base or PI film, PE thin
The fexible films such as film, the first metal layer and second metal layer are first produced on the transparent substrate, then are fitted in terminal and are set
On standby terminal cover board, to form GG(Glass-Glass) or GF(Glass-Film) structure.
A protective film is fitted in the second metal layer, to protect to second metal grill 21, it is preferable that
The protective film is rupture pressure disc, to improve the reliability and explosion-proof of the metal grill touch screen, is suitable for vehicle-mounted or industrial aobvious
Show device.
The above-mentioned embodiments merely express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
