Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail:
As in figure 2 it is shown, a kind of touch screen, including be provided with the mutual capacitance of emitter stage and receiving pole, (accompanying drawing is not marked
Know), fold the first conductive layer the 10th, first substrate 20 and the second conductive layer 30 that set successively from top to bottom, first
Being provided with emitter stage in conductive layer 10, the second conductive layer 30 is provided with ground wire, and first substrate 20 is provided with and ground wire
The golden finger (accompanying drawing does not identifies) connecting, wherein launches extremely TX, receives extremely RX.
During processing, the first conductive layer 10 is provided with the line pattern needed for emitter stage, and the second conductive layer 30 is provided with
Ground wire simultaneously overlaps with golden finger, it is achieved the interference of shielding liquid crystal.Ground wire is provided separately within by the utility model
On two conductive layers 30, increase the area of ground wire, advantageously reduce the interference of environment, improve the anti-interference of product
Property, product reliability is good.After machining, in order to prevent damaging in circular flow, at emitter stage
The side laminating second substrate 60 of line layer first substrate 20 dorsad, as process protective substrate, goes the most at last
Remove.Touch screen of the present utility model both can make individual layer multipoint configuration, it is also possible to makes hop structure or double
Layer film structure.
In the present embodiment, first substrate 20 and second substrate 60 are transparency carrier, wherein first substrate
20 is PET film, and second substrate 60 is turnover PET film, and first substrate 20 and second substrate 60 also may be used
