First screen layer 451 in certain embodiments, 541,641 and the material of secondary shielding layer 452,542,642 can be
Opaque material, including metal and alloy etc., for example, can be copper, nickel or its alloy etc.；The screen layer can also be saturating
Bright conductive material, such as ITO, IZO, nanometer silver, metal grill, Graphene or nanotube etc..
In certain embodiments, the material of the base material 462,562,652 of the first base material 461,561,651 and the second can be
Transparent conducting glass, cyclic polyolefin film, glass, cyclic olefin polymer, cyclic olefine copolymer, Merlon, poly- methyl-prop
E pioic acid methyl ester, transparent pi, mylar, polyethylene terephthalate or tri acetyl cellulose.
In certain embodiments, cover sheet 41 can be glass (such as sapphire etc.), protecting film, glued membrane or plastics
Plate.Pressure sensitive layer 471,571,671 and pressure-driven layer 472,572,672 be ITO, IZO, nanometer silver, metal grill or
Nanotube, can be radium-shine by ito thin film or etching, the upper silk-screened conductive slurries of PET, carbon nano-tube film or graphene film enter
The mode such as radium-shine of going is obtained, it is also possible to be made up of metal grill (Metal-mesh), you can with by forming conductive on base material
The mode of metal grill obtains required electrode pattern.The electrode of pressure sensitive layer 471,571,671 and pressure-driven layer
472,572,672 conductive electrode is arranged perpendicularly, in horizontal two-dimension graphic memory in the intersection region of certain area, so as to
Form some capacitance sensors that can be used to detect power.The detection of the capacitance of the capacitance sensor for being formed is existing with current
The test mode of capacitive touch screen is identical.Pressure sensitive layer 471,571,671 and pressure-driven layer 472, leading in 572,672
Electrode can also can be other shapes for some strip shaped electric poles, such as by a plurality of chain form for being connected with multiple electrodes block.
This utility model by by first screen layer and pressure sensitive layer be arranged on the relative first surface of the first base material and
Second surface, is arranged on the relative first surface of the second base material and second surface, in reality by pressure-driven layer and secondary shielding layer
Now touch and electromagnetic interference can be reduced during pressure sensitive, sensitivity is improved, while arranging through hole in corresponding stepped construction
Either tinfoil paper strip electrode incoming call connection pressure sensitive layer (or pressure-driven layer) and screen layer, can avoid the need for multiple flexibilities
The two-sided binding of circuit board, so as to simplify processing technology, improves yield, reduces cost.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, some deformations and improvement can also be made, these are belonged to
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
