In Figure 13, on the electrode of incidence surface one side, apply the electric signal that electric polarity is contrary with reflective hemisphere.Half spheroid of e-inks 132 is reflective, and is electronegativity, and another half spheroid is light tight, and is electropositivity, does as a wholely, and e-inks 132 integral body are electropositivity.Now, the first electrode structure 133 and the second electrode structure 134 in raster unit are all bipolar electrode structures, comprise respectively two sub-electrodes that are oppositely arranged, wherein the second electrode structure 134 comprises the electrode that is located at cavity bottom and top, and the first electrode structure 133 comprises the electrode being located on two sidewalls that are oppositely arranged.While forming light restraining barrier at needs in container cavity, can on second electrode structure 134 at cavity top, apply negative voltage, on the second electrode structure 134 of cavity bottom, apply after positive voltage (is to apply the electric signal that electric polarity is contrary with light tight hemisphere on the electrode of exiting surface one side, on the electrode of incidence surface one side, apply the electric signal that electric polarity is contrary with reflective hemisphere), e-inks 132 moves to cavity top under the effect of electric field E, forms and hinders the restraining barrier that incidence surface light enters.When needs form light transmission passage in container cavity, can on left side the first electrode structure 133 shown in Figure 13, apply negative voltage, on the first electrode structure 133 of right side, apply positive voltage, now e-inks 132 moves near the side-walls the first electrode structure 133 of left side, make the incident ray of incidence surface be able to by.
Above Figure 11-13 for example in, the overall electrode of e-inks is identical with light tight hemispheroidal polarity.Be appreciated that, in the utility model embodiment, the overall electrode of e-inks can be identical with reflective hemispheroidal polarity, in this case, when realizing restraining barrier and wish reflective hemisphere towards incidence surface one side, the electric signal applying is with above identical for example.Difference is, because e-inks overall electrode is with above contrary for example, therefore, the region that e-inks moves to is contrary with Figure 11-13, and for example, in the diagram of the left side of Figure 11, e-inks moves to cavity top area, and in the situation that the overall electrode of e-inks with can be identical with reflective hemispheroidal polarity, e-inks will move to cavity bottom region, for saving length, repeat no more.
Partial electrode structure and the electric field/voltage applying mode that more than only for the utility model, can adopt for example.Under the enlightenment of above structure, those skilled in the art can understand, and can also adopt single electrode at the first electrode structure, and the second electrode structure adopts bipolar electrode, or adopts single electrode at the second electrode structure, and the first electrode structure adopts bipolar electrode.Further, the utility model embodiment can also adopt different electrode structures in different raster units, for saving length, repeats no more.
Finally, the e-inks described in the utility model embodiment is briefly described.In the utility model embodiment, e-inks can be to be formed by polymers manufacturing.Preferably, this e-inks can be a kind of charged e-inks spheroid, and is half black half white type, comprises a black hemisphere and a white hemisphere.Wherein black part mainly plays extinction/stop the effect that light passes through, and white portion mainly plays reflection action.Charged ball black part is with positive charge, and white portion is with negative charge, and integral body can present electropositivity.This electric globule can adopt existing microchannel method to make.
Microchannel manufacture method is to use painted external phase and spherical particleization to have each other mutually the relation that is O/W (oil-in-water) or W/O (Water-In-Oil) type, from transferring the first microchannel of painted external phase, to the spherical particleization of flow media mobile in the second microchannel mutually in, spray successively the painted external phase of 2 looks, produce thus 2 form and aspect sphere polymers particles and aspect electric charge, there is the bipolarity peloid bulbec of positive-negative polarity.Concrete:
In the mobility medium of the oiliness that contains polymerism resinous principle or water-based, utilization be take the polymerizable monomer of mutually different positive negative charging and is formed on and in this medium, contains the polymerism resinous principle in the painted external phase that insoluble painted phase-splitting of dying pigment is 2 looks, and is transplanted on the first microchannel;
Next, by this painted external phase, continuously or the spherical particleization that is intermittently ejected into successively water-based mobile in the second microchannel or oiliness mutually in;
Next, be ejected into the ejecta of spherical particleization in mutually, on one side in a series of ejection/dispersion/handover in microchannel by spherical particle, on one side spherical particleization mutually in by spherical materialization successively, therefore, make the polymerism resinous principle polymerization sclerosis under U V irradiates and/or under heating in this spheroidizing particle, thereby bead is suitably modulated.
Above-mentioned painted external phase, by phase-splitting, be the continuous form and aspect of 2 form and aspect, for example, can list from black/white as the colorant that forms this form and aspect, can in the mobility dispersion medium that contains polymerism resinous principle described later, have insoluble or dispersed, do not do special restriction, can suitable selection and use.
As above-mentioned colorant, the main carbon black of selecting of black part, white portion, in order to reach better reflecting effect, mainly adopts chemical silver plating method to realize.
In the manner, can be with respect to every 100 weight portions of full polymerism resinous principle of the polymerization hardener as in painted external phase, with 0.1 weight portion～80 weight portion, the scope that is preferably 2 weight portion～10 weight portions is suitably added well.
As the polymerism resinous principle (or polymerizable monomer) using in above-mentioned ball, according to functional group or the substituent kind of reversing the polymerizable monomer using in ball, can list the monomer kind that charging property in above-mentioned torsion ball demonstrates respectively (-) charging property and (+) charging property tendency.Therefore, in the situation that using various of monomer at least of more than two kinds polymerism resinous principle in the manner and using, known its shows (+) and (-) charging property tendency, is preferably, by a plurality of combinations and suitably using aptly each other of the monomer in charging property tendency of the same race.
Above, use painted external phase and spherical particleization to have each other mutually the relation of O/W type or w/o type, from transferring the first microchannel of painted external phase, to the spherical particleization of flow media mobile in the second microchannel mutually in, spray successively the painted external phase of 2 looks, produce thus 2 form and aspect sphere polymers particles and aspect electric charge, there is the bipolarity spherical particle of positive-negative polarity.And black and white live part institute is electrically charged asymmetric, thereby keeps on the whole a kind of charged type, rather than electric neutrality.
More, about microchannel manufacture method, can also, with reference to the patent application document of Chinese Patent Application No. 200380104921.2, for saving length, repeat no more herein.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
