Below with reference to accompanying drawings specific embodiments of the present invention is explained in more detail, wherein:
Fig. 1 is the synoptic diagram according to the electric paper apparatus of first embodiment of the invention;
Fig. 2 is the synoptic diagram of the electrode strip of lower floor's anisotropic conductive film;
Fig. 3 is the synoptic diagram of the electrode strip of upper strata anisotropic conductive film;

Embodiment
Anisotropic conductive film is the novel conductive film that grew up in recent years.It comprises a plurality of orderly CNTs, and these CNTs are arranged of preferred orient along same direction.Carbon nano-tube film comprises single-walled nanotube, double-walled nanotubes and many walls nanotube.In an example, can adopt preparation carbon nano pipe arrays such as carbon-source gas reaction method, graphite electrode Constant Electric Current arc discharge sedimentation, laser evaporation sedimentation, adopt stretching tool from carbon nano pipe array, to pull then and obtain the carbon nanometer film.Because the effect of Van der Waals force, a plurality of CNT segments are pulled out respectively end to end, and the orientation of CNT is basically parallel to the draw direction of carbon nano-tube film thus.
The conducting film that forms thus improves a lot aspect conductivity, and shows significant anisotropism.Through selecting CNT in the orientation on the same film and be controlled at uniformly dispersed on the direction vertical, can select the conducting direction of conducting film with orientation.Can in conducting film, form many buss of evenly equidistantly arranging along conducting direction.
Fig. 1 is the synoptic diagram according to the electric paper apparatus of first embodiment of the invention.As shown in Figure 1, electric paper apparatus comprises substrate 110, lower floor's anisotropic conductive film 120, Electronic Paper 130 and upper strata anisotropic conductive film 140.
Lower floor's anisotropic conductive film 120 follows the direction conduction, insulate along column direction.Nano conducting powders in the conducting film is arranged according to the order of sequence, thereby forms many electrode strips that follow direction, equidistantly arrange.Therefore, the direction of lower floor's anisotropic conductive film 120 its high conductivities of employing is as conducting direction.The synoptic diagram of the electrode strip of lower floor's anisotropic conductive film 120 is referring to Fig. 2.The electrode strip number scale is M.Also having illustrated among Fig. 2 through these electrodes, can provide driving voltage to electric paper apparatus by the electrode 210 that several orientations are vertical with line direction.
Upper strata anisotropic conductive film 140 follows the direction insulation along the column direction conduction.Nano conducting powders in the conducting film is arranged according to the order of sequence, thereby forms many along column direction, the equidistant electrode strip of arranging.Therefore, the direction of upper strata anisotropic conductive film 140 its high conductivities of employing is as conducting direction.The synoptic diagram of the electrode strip of upper strata anisotropic conductive film 140 is referring to Fig. 3.The electrode strip number scale is N.
Certainly; The conducting direction of lower floor's anisotropic conductive film 120 and upper strata anisotropic conductive film 140 can change; Upper strata anisotropic conductive film 140 follows the direction conduction such as lower floor's anisotropic conductive film 120 changes into along column direction conduction, as long as both conducting directions are perpendicular to one another.
In an example, can on the anisotropic conductive film of upper strata, paste layer protective layer, play protective effect to anisotropic conductive film.
When needs to certain point (m for example, n, 0＜m＜M, 0＜n＜when N) writing or rewriting, drive lead-in wire that links to each other with m column electrode bar and the lead-in wire that links to each other with n row electrode strip with different voltages with different respectively.Such as the lead-in wire that links to each other with positive voltage driving m column electrode bar, the lead-in wire that links to each other with n row electrode strip with negative voltage driving.Therefore, Electronic Paper (m, n) some place upper and lower has different voltages with different respectively.If this voltage and voltage before are different, then cause the display change of this pixel.
Fig. 4 is the synoptic diagram according to the electric paper apparatus of second embodiment of the invention.Electric paper apparatus comprises substrate, lower floor's anisotropic conductive film, Electronic Paper and upper electrode plate.From the purpose of simple signal, only illustrated in the drawings lower floor's anisotropic conductive film and upper electrode plate to have omitted substrate and Electronic Paper part.
The same with first embodiment, in the present embodiment, substrate can be transparency carrier, such as but not limited to materials such as glass, plastics.Electronic Paper can adopt cholesterol liquid crystal display technique, electrophoretic display technology (EPD) or electric wetting display technique or the like preparation
Lower floor's anisotropic conductive film 420 has the high conductivity direction of the direction of following, and therefore follows the direction conduction, insulate along column direction.Nano conducting powders in the conducting film is arranged according to the order of sequence, thereby forms many electrode strips that follow direction, equidistantly arrange.
Upper electrode plate 220 by many along column direction, equidistantly arrange electrode strips (440-1 ..., 440-n ... 440-N) constitute, therefore along the column direction conduction, follow the direction insulation.Battery lead plate can be processed by transparent material.
When needs write or rewrite certain point, respectively with different voltages with different drive with lower floor anisotropic conductive film 420 on the lead-in wire that links to each other of m column electrode bar and the lead-in wire that links to each other with n row electrode strip on the upper electrode plate 220.Such as the lead-in wire that links to each other with positive voltage driving m column electrode bar, the lead-in wire that links to each other with n row electrode strip with negative voltage driving.Therefore, Electronic Paper (m, n) some place upper and lower has different voltages with different respectively.If this voltage and voltage before are different, then cause the show state of this pixel to change.
Obviously, the present invention described here can have many variations, and this variation can not be thought and departs from the spirit and scope of the present invention.Therefore, the change that all it will be apparent to those skilled in the art all is included within the covering scope of these claims.
