Flexible display screen 25 is LCD display, LED display, OLED display screen, CNT CNT
Any one in display screen, display paper or Graphene display unit.
Graphene film 21 is arranged between flexible base board 23 and cover plate 22.Cover plate 22 and Graphene
Thin film 21 is bonded together by optics gelatin 24.Flexible base board 23 be transparent glass plate, film,
Any one in acrylic board, poly (methyl methacrylate) plate or PC composite plate.
This utility model also includes flexible PCB 26.Flexible PCB 26 is with graphene film 21 even
Connect for calculating touch point and being sent to processor and process.
Graphene film 21 can be made up of graphene fiber braiding, it is also possible to by graphene fiber and stone
Ink alkene bar section combined knitting is constituted.As shown in Figure 6, graphene fiber 1 has braiding overlap joint each other
Point 11.It is positioned at the graphene fiber at braiding overlapped points 11 contact with each other and produce certain bending, mutually
Get around.Particularly, there is weak section 12 in the graphene fiber around braiding overlapped points 11.It is positioned at
The graphene fiber microstructure of weak section 12 is relatively weak, loose, wherein has crackle.Concrete table
Being now that the spacing between graphene wafer is relatively big, the number of plies of wafer is the most relatively fewer.When graphene film 21
When producing tensile deformation, weak section 12 easily produces bigger crackle and/or fracture separates, and constitutes open circuit.
It addition, in braiding overlapped points 11, there is between graphene fiber bigger contact resistance.Work as Graphene
When thin film 21 produces deformation, between the graphene fiber of braiding overlapped points 11, relative displacement can be produced,
Close to each other or be located remotely from each other, cause the contact resistance between graphene fiber to increase or reduce.

Connect composition.Graphene band can be arranged in order or be arranged side by side, and scrabbles up and has segmentation structure
Graphene fiber.
Under in working order, touch screen alives.When graphene film produces tensile deformation, weak
Section 12 cracks and/or ruptures, and the resistance of graphene film is substantially increased thus electric current is produced shadow
Ring.When graphene film produce vibration time, braiding overlapped points 11 on graphene fiber bonding state and
The structure impact vibrated of weak section 12, causes the resistance variations of graphene film thus affects electric current.
Graphene film, by macroscopic view braiding structure and the common effect of microstructure, had both had good deformation
Amount, has again bigger resistance-strain sensitivity coefficient.

Ink alkene wafer stacking is arranged in flake type structure.Flake type structure is a kind of film configuration, and this structure has row
Arrange little wafer regular, that be stacked with to constitute, not only maintain the characteristic of single wafer itself, also make
Integral membrane structure becomes soft, it is possible to realize the deformation of large scale, wide-angle.Stone when flake type structure
When ink alkene material produces tensile deformation, the lap W between wafer and wafer0Can reduce, i.e. Fig. 7
Middle W0Diminishing, thus cause the electric conductivity of grapheme material to reduce, resistance rises.So, by micro-
Seeing structure is that the graphene film that is knitted to form of the grapheme material of flake type structure has more preferable deformation
Ability and higher resistance-strain sensitivity coefficient.
The graphene film 21 being knitted to form by graphene fiber can have the pore structure of rectangle, also
Can have the pore structure structure of triangle.Such as, graphene film 21 can be by longitudinal Graphene
Fiber and the braiding of horizontal graphene fiber are constituted.Graphene film 21 has rectangular apertures, Graphene
Fiber intersects vertically at braiding overlapped points 11.Or, graphene fiber is knitted to form from three directions
Graphene film 21, so that the graphene film 21 formed has triangle hole.There is three-dimensional
Graphene film 21 structure of fiber is more stable, it is possible to the stretcher strain to all directions responds.
Those skilled in the art can also form graphene film 21 with other type of weaves.This utility model is not
It is limited to the graphene film 21 with rectangular apertures and triangle hole.
