Description
Technical field
The utility model is related to a kind of thick cover board capacitance projection-type touch modules.
Background technology
In the prior art, the cover sheet thickness for holding projection touch-screen is 0.4mm-1.5mm, is mainly used for small-medium size, because
The touch module deformation of small-medium size is relatively small.But this structure can not meet large-sized touch module, be squeezed in external force
It is big that pressure is easy to cause deformation.
Utility model content
Shortcoming present in regarding to the issue above, the utility model provide a kind of thick cover board capacitance projection-type touch-control mould
Group, case hardness is high, and mechanical deformation is small, highly reliable, the function modules such as SENSOR below the preferable cover sheet glass of energy.
To achieve the above object, the utility model provides a kind of thick cover board capacitance projection-type touch module, including cover board glass
Glass, OCA optical adhesive layers and sensor layer, the sensor layer are fitted in the cover-plate glass by the OCA optical adhesive layers
Lower surface；
Wherein, the thickness of the cover-plate glass is 3.4~4.6mm, and the thickness of the OCA optical adhesive layers is 0.175mm, institute
The thickness for stating sensor layer is 0.55mm.
It is further improved as the utility model, the thickness of cover-plate glass is 3.4mm.
It is further improved as the utility model, the thickness of cover-plate glass is 4.6mm.
It is further improved as the utility model, the unilateral length of OCA optical adhesive layers surrounding is equal to the sensor
The layer unilateral length of surrounding, and the edge of the OCA optical adhesive layers is close to the edge of the sensor layer；
The unilateral length of cover-plate glass surrounding is all higher than being equal to the unilateral length of OCA optical adhesive layers surrounding, and described
Cover-plate glass is fully wrapped around by the OCA optical adhesive layers.
It is further improved as the utility model, being bound on the sensor layer has FPC.
The beneficial effects of the utility model are：
1st, cover-plate glass thickness increases so that the surface strength of touch module, which has, significantly to be promoted, module entirety
Flexural capacity promoted, resistance to compression prevents that pounding performance gets a promotion, better reliability；
2nd, case hardness is high, and mechanical deformation is small, highly reliable, the functions such as SENSOR below cover sheet that can be relatively good
Module can make touch module be applied to broader field, such as smart home, commercial Application, banking terminal device etc.；
3rd, while touch-control effect is taken into account, meet highest reliability conditions, solve large scale conventional cover plate touch module
The problem of deformation is big under external force extruding.

In figure：
1st, cover-plate glass；2nd, OCA optical adhesive layers；3rd, sensor layer.
Specific embodiment
As shown in Figure 1, a kind of thick cover board capacitance projection-type touch module of the utility model embodiment, including cover-plate glass
1st, OCA optical adhesive layers 2 and sensor layer 3.Sensor layer 3 is fitted in the lower surface of cover-plate glass 1 by OCA optical adhesive layers 2.Its
In, the thickness of cover-plate glass 1 is 3.4~4.6mm, and the thickness of OCA optical adhesive layers 2 is 0.175mm, and the thickness of sensor layer 3 is
0.55mm.Binding has FPC on sensor layer 3.
The unilateral length of 2 surrounding of OCA optical adhesive layers is equal to the unilateral length of 3 surrounding of sensor layer, and OCA optical adhesive layers 2
It is close to the edge of sensor layer 3 at edge.Preferably, the unilateral length of 2 surrounding of OCA optical adhesive layers is equal to 3 surrounding of sensor layer
Unilateral length.
The unilateral length of 1 surrounding of cover-plate glass is all higher than being equal to the unilateral length of 2 surrounding of OCA optical adhesive layers, and cover-plate glass 1 will
OCA optical adhesive layers 2 are fully wrapped around.
Preferably, the thickness of cover-plate glass 1 is 3.4mm.At this point, by touch module carry out three-point bend test, 4 points it is curved
Bent test, bicyclic strength test, ball falling impact test, test result show the anti-of the touch module of the cover-plate glass of 3.4mm thickness
Folding endurance energy, bending resistance and shock resistance are all higher than the touch module of general thickness cover-plate glass (0.4mm-1.5mm).Together
When, the parameter of modification touch-control IC can be so that the properties of touch module reach industry level.
Preferably, the thickness of cover-plate glass 1 is 4.6mm.At this point, by touch module carry out three-point bend test, 4 points it is curved
Bent test, bicyclic strength test, ball falling impact test, test result show the anti-of the touch module of the cover-plate glass of 4.6mm thickness
Folding endurance energy, bending resistance and shock resistance are all higher than the touch module of general thickness cover-plate glass (0.4mm-1.5mm).Together
When, the parameter of modification touch-control IC can be so that the properties of touch module reach industry level.
In addition, increasing with the thickness of cover-plate glass, the mechanical performances such as fold resistance, bending resistance can all have a degree of
Increase namely the performance of 4.6mm thickness is better than 3.4mm.But with the increase of thickness, touch-control performance has a degree of decrease,
Because the driving force of touch-control IC is limited at this stage, the limit that cover board thickens is also limited, within certain thickness, some effects
Fruit is all that can optimize, and can be improved, but after thickness reaches certain value, a part of performance in can only ensureing.According to more
Secondary test verification, the thickness of the cover-plate glass of the utility model is preferably in the range of 3.4~4.6mm.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
