Embodiment

See also shown in the accompanying drawing 1,2,3, one has the current type touch screen 10 that the plural layer material is constituted, system is printed on one to have on the plastic transparent thin slice 12 of pliability, constitutes a pliability current type touch control sheet 100, and this touch control sheet 100 can be done the pliability bending between 0 to 180 degree at least; Wherein, its flexible of touch control sheet 100 mats, or be attached on the display panel of the bent radian of any tool on 85, on plastic transparent thin slice 12, can print the touch screen 10 more than at least, and can be attached on the collapsible display panel; Wherein, the plural layer material of touch-control control screen 10 comprises:

One is transparent or be tending towards the ITO conductive film 20 of transparence, is printed in the surface of plastic transparent thin slice 12 with mode of printing;

One thin shape protective seam 30 transparent or that be tending towards the transparence conduction is printed on the ITO conductive film 20 with mode of printing;

Once insulation course (isolation) is printed in the edge all around of protective seam 30 with rectangular box-like;

One plural silver-colored line layer 50 (silver printing) is printed in down on the surface of insulation course 40 with mode of printing;

One rectangular linear layer 60 (linerization pattern) is printed on the protective seam 30 with mode of printing, and is positioned at the frame inboard of silver-

colored line layer

50, and 60 4 jiaos of systems of linear layer are connected with

link

51,52,53,54 within the silver-colored line layer 50;

Insulation course on one (isolation) 70 is to be one rectangular box-like, is printed on silver-colored line layer 50 and the linear layer 60 with mode of printing.

Another flexible flat cable 80 (tail) link 80a system is connected with link 50a outside the silver-colored line layer 50, the current value signal output that 100 receptor sites of touch control sheet can be touched, but the bottom surface mat layer of transparent adhesive 121 of plastic transparent thin slice 12 is attached on the display panel 85 uniformly; The utility model has following characteristics when implementing:

1, described plastic transparent thin slice 12 preferably is made of the PE plastic material, thickness is good between 0.3-1.5mm preferably, as shown in Figure 6, full wafer touch control sheet 100 two ends are stressed, can do the bending of some angles, base two ends angle of bend each other can be between between the 0-180 degree, because the prosperity of information industry, some individual figure place processor (PDA) or e-book or mobile telephones ... devices such as .., its display panel no longer is restricted to planarity, display panel can be designed to arc or collapsible, see also shown in the accompanying drawing 7, but the transparent stick 121 of touch control sheet 100 its plastic transparent sheet 12 bottom surface mats is attached at display panel 85 (LED uniformly, LCD) on the arcwall face, further make the display panel (LED of tool curved surface, LCD) after the binding of the utility model touch control sheet 100, make the user can finger or other conductors to the some contact of touch control sheet 100, can be write, drawing, click every functions such as guiding.

2; see also accompanying drawing 1; shown in 2; the material of conductive film 20 can be a tin indium oxide (ITO:Indium Tin Oxide); it is with mode of printing; be printed on plastic transparent thin slice 12 surfaces with quite thin thickness; and make conductive film 20 be transparence or be tending towards transparent; because conductive film 20 is to be distributed on the plastic transparent thin slice 12 with as thin as a wafer sample attitude; therefore, very easy impaired by scratch, therefore; conductive film 20 upper surfaces must republish the thin shape protective seam 30 that one deck has higher hardness; avoiding conducting electricity spinach film 20 by scratch, this protective seam 30 is that the film by layer of transparent is constituted, and has electric conductivity.

Following insulation course 40 is the rim all around that is printed in protective seam 30 with the kenel of framework; linear layer 60; system is mixed with contact agent solution with the silver powder and the carbon dust of high conductive material; become a kind of ink lay that prints; so linear layer 60; be actually an ink lay (C-Slier); with this material on protective seam 30 peripheries; print out a frame line body; in other words; be to print out uniform resistance frame line periphery outside protective seam 30; silver line layer 40 cording have the silver slurry lines of plural number, directly are printed in down with mode of printing on the surrounded surface of insulation course 4, and wherein silver-colored line layer 40 preferably is distributed as good with four bullion lines; link 51 within its four silver medal line; 52; 53; 54 are connected to the link 80a of a flexible flat cable 80, and winding displacement 80 outer links are to be connected with controller (not showing on the figure).

Last insulation course 70 is with mode of printing, is printed on linear layer 60 and the silver-colored line layer 50, with

linear layer

60 and 50 insulation of silver-colored line layer, forms a current type touch screen 10 and is printed on the pliability plastic transparent thin slice 12.

Controller (not showing on the figure), can export four four corners of waiting voltage to this touch screen linear layer 60, and the variations of measuring the last electric current in touch screen 10 surfaces at any time, see also accompanying drawing 4, when the user touches at the surface point of touch control sheet 100 with finger or conduction utensil, promptly produce capacity effect, promptly the equivalent voltage Va that is exported by controller is in four ends of linear layer 60, these four are waited voltage can measure the current reference value Ia of the electric current variation of capacity effect, to determine the position of contact, point touches the position difference, the reference value Ia of electrorheological galvanic current is promptly different, controller changes reference value with the electric current that detects and does the interpretation processing by the controller CPU in the host computer, and this interpretation is handled the current reference value Ia of back, it changes signal and is manifested by plastic transparent thin slice 12 by transmission display panel 80, then the user directly the touch screen on transparent sheet 12 10 directly write, draw or click every function (as the switching of function form).

3, please join accompanying drawing 8,9, touch control sheet 100 is installed in an embodiment in the collapsible electrical equipment 90, a slice plastic transparent thin slice 12 is printed in the touch screen 10 of two independences simultaneously, 10 ', cording has two independent displaying panels 85 in the electrical equipment 90,85 ', the adhesive 121 that the back side mat of a slice plastic transparent thin slice 12 is transparent evenly is attached at display panel 85,85 ', and make the touch screen 10 of two independences, 10 ' respectively correspondence be attached at display panel 85, on 85 ', by this when electrical equipment 90 folds, touch control sheet 100 can be done and be tending towards angle 180 degree and also do not have any folding line with interior pliability bending and produce, further when electrical equipment 90 was opened, touch control sheet 100 is recovery of elasticity original state (plane) rapidly.
