piezoelectric as example as ZnO, because its direction of growth is corresponding to the C direction of principal axis of ZnO crystal, because the existence of ZnO material piezoelectric effect will be at the high electromotive force of the top of the first piezoelectric nano linear array 15 generation, at the low electromotive force of the bottom of the first piezoelectric nano linear array 15 generation.At this moment, if external circuit is conducting state, for example as shown in Figure 9, the first electrode 11 is connected by reometer 31 with third electrode 17, free electron will flow to from the first electrode 11 of the lower bottom of electromotive force the third electrode 17 at the higher top of electromotive force so, thereby in the external circuit of the first piezoelectric nano master section, form electric current, namely have electric current to flow through from reometer 31.And the third high Molecularly Imprinted Polymer insulation course 16 of the first piezoelectric nano linear array 15 tops will prevent that electronics from neutralizing in inside.When each layer of this mixing nano generator returns to original state, each layer in the first piezoelectric nano master section also recovers its original dull and stereotyped state, because the existence of ZnO material piezoelectric effect will produce electric potential difference again between the top of the first piezoelectric nano linear array 15 and bottom, at this moment free electron will be from third electrode 17 via external circuit (namely, the circuit that connects the first electrode 11 and third electrode 17 through reometer) flowing back into an original lateral electrode is on the first electrode 11, thereby forms inverse current in external circuit.The electricity generating principle of the electricity generating principle of the second piezoelectric nano master section and the first piezoelectric nano master section recited above is similar, when each layer of this mixing nano generator is bent downwardly, the first piezoelectric nano linear array 15 in the first piezoelectric nano master section is in extended state, and the second piezoelectric nano linear array 18 of the second piezoelectric nano master section is in compressive state, because the existence of ZnO material piezoelectric effect will be on the top of the second piezoelectric nano linear array 18 (because the second piezoelectric nano linear array 18 be growths downwards, its top is corresponding to the bottom of the second piezoelectric nano linear array 18 among the figure) produce low electromotive force, produce high electromotive force in the bottom (top of the second piezoelectric nano linear array 18 in corresponding to figure) of the second piezoelectric nano linear array 18.At this moment, if external circuit is conducting state, for example as shown in Figure 9, the second electrode 13 connects by reometer 32 with the 4th electrode 20, free electron will flow to the second higher electrode 13 of electromotive force from the 4th lower electrode 20 of electromotive force so, thereby in the external circuit of the second piezoelectric nano master section, form electric current, namely have electric current to flow through from reometer 32.And the 4th high molecular polymer insulation course 19 on the second piezoelectric nano linear array 18 tops will prevent that electronics from neutralizing in inside.When each layer of this mixing nano generator returns to original state, each layer in the second piezoelectric nano master section also recovers its original dull and stereotyped state, because the existence of ZnO material piezoelectric effect will produce electric potential difference again between the top of the first piezoelectric nano linear array 18 and bottom, at this moment free electron will be from the second electrode 13 via external circuit (namely, the circuit that connects the second electrode 13 and the 4th electrode 20 through reometer) flowing back into an original lateral electrode is on the 4th electrode 20, thereby forms inverse current in external circuit.Because two groups of piezoelectric nano master sections are relatively independent, so the two is each other without impact.In sum, this mixing nano generator is comprised of three parts, i.e. two piezoelectric nano master sections and a friction susceptance rice master section between described two piezoelectric nano master sections.When the first electrode 11 and the 4th electrode 20 are linked together as an output branch road, when the second electrode 13 and third electrode 17 link together as an output branch road, this three part satisfies the linear superposition theorem that basic circuit connects, i.e. Downward addition or when oppositely superposeing, total output current can be enhanced in parallel no matter.
Therefore, when using this to mix nano generator, be equivalent in single mixing nano generator, can realize the parallel connection of three nano generators (two piezoelectric nano generators and a friction susceptance rice generator), so that the generating efficiency of nano generator is obviously promoted.Therefore, utilize this friction susceptance rice generator not only can realize the self-energizing of the liquid crystal display among the utility model embodiment and the full flexible design of liquid crystal display, but also can improve the generating efficiency of generator.
The above introduces as example as 611 as friction susceptance rice generator and piezoelectricity and friction electricity mix this dual mode of nano generator take nano generator, those skilled in the art should be understood that, nano generator in the flexible liquid crystal display of the utility model embodiment is 611 can also pass through an independent piezoelectric nano generator, perhaps, realize by a plurality of mixing nano generator stacks.
In addition, friction susceptance rice generator can also adopt another structure shown in Figure 10 to realize except can adopting structure shown in Figure 4.The key distinction of friction susceptance rice generator shown in Figure 10 and friction susceptance rice generator shown in Figure 4 is, need not to make film between two parties, directly generates electricity by the friction between two high molecular polymers insulation.
Friction susceptance rice generator shown in Figure 10 comprises the first electrode 11, the first high molecular polymer insulation course 10, the second high molecular polymer insulation course 12 and the second electrode 13.Particularly, the first electrode 11 is positioned on the first side surface 10a of the first high molecular polymer insulation course 10, and the second electrode 13 is positioned on the first side surface 12a of the second high molecular polymer insulation course 12.The first electrode 11 and the second electrode 13 can be the metallic film of conduction, and it can be plated on the surface of corresponding high molecular polymer insulation course by vacuum sputtering or vapour deposition method.Wherein, the second side surface 12b of the second high molecular polymer insulation course 12 contacts with the second side surface 10b of the first high molecular polymer insulation course 10, and on the second side surface 12b of the second high molecular polymer insulation course 12, and on the second side surface 10b of the first high molecular polymer insulation course 10, be respectively equipped with micro-nano concaveconvex structure 80.Therefore, between the micro-nano concaveconvex structure 80 on the second side surface 10b of the micro-nano concaveconvex structure 80 on the second side surface 12b of the second high molecular polymer insulation course 12 and the first high molecular polymer insulation course 10, form a frictional interface.Particularly, the second high molecular polymer insulation course and the first high molecular polymer insulation course be over against applying, and at the edge of two weak points by common adhesive plaster sealing, guarantee the appropriateness contact of two polymer insulation layer.Certainly, also can be fixed in other way contact between the second high molecular polymer insulation course and the first high molecular polymer insulation course.
Figure 10 shows the synoptic diagram of micro-nano concaveconvex structure 80 of the second side surface 10b of the second side surface 12b of the second high molecular polymer insulation course 12 and the first high molecular polymer insulation course 10, this micro-nano concaveconvex structure can increase frictional resistance, improves generating efficiency.Described micro-nano concaveconvex structure can directly form when film preparation, and method that also can enough polishings makes the surface of high molecular polymer film form irregular micro-nano concaveconvex structure.Particularly, Figure 10 shows semicircular micro-nano concaveconvex structure, and in Figure 10, the recess of the micro-nano concaveconvex structure of the second side surface 12b of the second high molecular polymer insulation course 12 is relative with the protuberance of the second side surface 10b of the first high molecular polymer insulation course 10, so that the contact area between the micro-nano concaveconvex structure is maximum, therefore, the micro-nano concaveconvex structure among Figure 10 is preferred version, can improve generating efficiency.But, what those skilled in the art should understand that is, also can make the protuberance of micro-nano concaveconvex structure of the second side surface 12b of the second high molecular polymer insulation course 12 relative with the protuberance of the second side surface 10b of the first high molecular polymer insulation course 10, perhaps, adjust the position relationship between recess and the protuberance, for example, it is not just relative making between recess and the protuberance, but certain distance that staggers a little, to regulate generating efficiency.And the shape of micro-nano concaveconvex structure also is not limited to this, can also be made into other shape, for example can be striated, cubic type, rectangular pyramid or cylindrical etc.In addition, this micro-nano concaveconvex structure be generally regular nanoscale to micron-sized concaveconvex structure (because the micro-nano concaveconvex structure is very little, in Figure 10 for so that the micro-nano concaveconvex structure can see clearly, therefore, the micro-nano concaveconvex structure is amplified, and namely the micro-nano concaveconvex structure among Figure 10 is that not to scale (NTS) is drawn.Those skilled in the art can be understood that in actual conditions, the micro-nano concaveconvex structure on the high molecular polymer insulation course is that nanoscale is to micron-sized very little concaveconvex structure).
The first above-mentioned high molecular polymer insulation course, the first electrode, the second high molecular polymer insulation course, the second electrode are the flexible flat structure, and they cause electrification by friction by crooked or distortion.Material about the first high molecular polymer insulation course, the first electrode, the second high molecular polymer insulation course, the second electrode can be selected with reference to friction susceptance rice generator shown in Figure 4.
The electricity generating principle of the electricity generating principle of friction susceptance rice generator shown in Figure 10 and friction susceptance rice generator shown in Figure 4 is similar, repeats no more herein.
