The light wave (Wave) that (not shown) is reflected is before the eyes for entering user first by destruction interference
(Destructive Interference) and repeal by implication, and then user is allowed not can be appreciated that the etched mark of sensor circuit layer 2
And achieve the effect that eliminate etched mark, and also simultaneously instead of index matching layer (Index in existing touch screen structure
Matching Layer) function.In addition, the refractive index for changing buffer layer 3 then can be by the clipped wire of change composition buffer layer 3
The modes such as material, quantity of son are reached, therefore, the metallic of composition buffer layer 3 need to regard the demand of 3 refractive index of buffer layer into
Row change, and the adjustment to 3 thickness of buffer layer of arranging in pairs or groups, to achieve the effect that and 1 index-matched of sensor circuit layer 2 and substrate.
In summary, in the present embodiment, buffer layer 3 can eliminate substrate 1 and induced electricity by lesser young's modulus
Stress between road floor 2.In addition, through the index matching of refractive index and sensor circuit layer 2 with substrate 1, to eliminate induced electricity

It tosses about, signal transport layer 7 is located at two opposite sides of the buffer layer 3 with shielding layer 6.Since sensor circuit layer 2 and signal pass
Sending layer 7 is the same side for being located at buffer layer 3, therefore signal transport layer 7 can be directly electrically connected with sensor circuit layer 2, so that this reality
The structure for applying example can more simplify, and then manufacturing cost can further be declined.And the feature of the present embodiment remaining each component
And material property is identical as above-mentioned 3rd embodiment, and so it will not be repeated.
Be the 5th embodiment of Touch Screen of the present invention refering to Fig. 5, the present embodiment and fourth embodiment the difference is that
