Flexible electronic control dimming medium of the present invention is produced by following method for making.As shown in Figure 2, this method for making comprises the steps:
Clean: first base layer 101 and second base layer 102 are cleaned up.
Electrode layer is established in plating: first conductive electrode layer 103 is established in plating on this first base layer 101, and second conductive electrode layer 104 (as Fig. 3 A) is established in plating on this second base layer 102.In actual the enforcement, if flexible electronic control dimming medium is applied in the production display screen, then establish first in plating, second conductive electrode layer 103, after 104, also need be on this first base layer 101, first conductive electrode layer 103 that plating is established carries out photoetching, make M strip line electrode that is arranged in parallel by lithography, and on this second base layer 102, second conductive electrode layer 104 that plating is established carries out photoetching, make N strip row electrode that is arranged in parallel by lithography, for the flexible electronic control dimming medium of having made, this M column electrode and this N row electrode should be perpendicular, and this M column electrode and this N row electrode have formed the pixel array of a M * N.
Coated polymer film: the thin polymer film 108 (getting final product UV cured polymer monomer) (as Fig. 3 B) that on this first conductive electrode layer 103, applies UV-curable.This coating step can adopt methods such as spin coating, spraying or silk-screen.
Place mask plate: have the mask plate 107 of setting pattern with one and place these thin polymer film 108 1 sides or this first base layer, 101 1 sides.Place in the mask plate step at this, if mask plate 107 is placed thin polymer film 108 1 sides, as Fig. 3 C-1, then mask plate 107 can not contact with thin polymer film 108,108 of mask plate 107 and thin polymer films are separated, generally, the distance that mask plate 107 and thin polymer film are 108 is greater than 5 μ m, ultraviolet light can directly be radiated on the thin polymer film 108 via the open-work on the mask plate 107, light utilization efficiency is higher, but because 108 of mask plate 107 and thin polymer films certain distance apart, thus mask plate 107 to put precision relatively poor.Certainly, can before placing the mask plate step, add a precuring thin polymer film step, at a certain temperature promptly, within a certain period of time, make this thin polymer film 108 of UV-irradiation of certain light intensity, thereby precuring thin polymer film 108, reduce the flowability of thin polymer film 108, like this, in ensuing placement mask plate step, mask plate 107 just can be close on the thin polymer film 108, has not only guaranteed efficiently light utilization efficiency but also has improved and put precision.If mask plate 107 is placed first base layer, 101 1 sides, as Fig. 3 C-2, then mask plate 107 can be close to first base layer 101, it is higher that mask plate 107 is put precision like this, but because ultraviolet light needs just can be radiated on the thin polymer film 108 via the open-work on the mask plate 107, first base layer 101 successively, thereby light utilization efficiency is lower.In actual the enforcement, the pattern of this mask plate 107 (being the shape, position, quantity etc. of open-work) should be suitable with pattern to be shown, the corresponding non-display area of open-work part on the mask plate 107, the corresponding viewing areas of other parts on the mask plate 107.For example, make row-column electrode by lithography as if establishing in the electrode layer step in plating, then the open-work on the mask plate 107 partly should correspondingly be answered non-pixel zone, and other parts on the mask plate 107 are corresponding corresponding with the pixel zone.
Cure polymer film: under design temperature, in one section setting-up time, make this mask plate 107 of UV-irradiation of setting light intensity, the corresponding part of open-work on this thin polymer film 108 and this mask plate 107 (for example point out among Fig. 3 D 1081) is cured because of the irradiation that is subjected to wearing via open-work the ultraviolet light of ejaculation, the remainder of this thin polymer film 108 (for example point out among Fig. 3 D 1082) is not because of relative with open-work on the mask plate 107, ultraviolet light can't shine on it, thereby maintain the original state (as Fig. 3 D), solidify the back that finishes and remove mask plate 107.In actual the enforcement, in this cure polymer film step, the light application time of temperature, ultraviolet light, the irradiates light of ultraviolet light depend on the material and the thickness of thin polymer film 108 by force.As can be known, in same light application time same thin polymer film 108 is cured in actual the enforcement, temperature is high more, and the irradiation light intensity of ultraviolet light is strong more, and curing rate is fast more; Under same temperature, same irradiation light intensity, thin polymer film 108 is thick more, and light application time required during curing is long more.Generally, Controllable Temperature is built in 0～100 ℃, and the irradiation light intensity of ultraviolet light can be controlled in 1W/cm
2～10000W/cm
2, the light application time of ultraviolet light can be between 1s～10h.
Clean the uncured polymer film portion: use the maintain the original state polymer thin membrane portions (for example point out among Fig. 3 D 1082) of (promptly uncured) of cleaning fluid flush away, formed accommodating chamber 1051 (as Fig. 3 E) by the polymer thin membrane portions of flush away, thereby accommodating layer 105 making finish.This cleaning fluid can use isopropyl alcohol, acetone or high purity water etc.The key factor that forms and influence accommodating layer 105 has: temperature, ultraviolet light light application time and light intensity etc. when the proportioning proportion of the kind of polymer monomer, polymer monomer, curing.
Fill the light modulation thing: under preset temperature (being controlled at-50 degree) between 150 degree, the light modulation thing 106 (as Fig. 3 F) that fillings in each accommodating chamber 1051 on this accommodating layer 105 are completely mixed.This filling light modulation thing step can adopt spraying, dip-coating, ODF or selectivity to apply methods such as (serigraphys).Wherein, spraying is to utilize flush coater that light modulation thing 106 is sprayed onto on accommodating layer 105 surfaces with vaporific form; Dip-coating is that the taking-up back dries, the uniform rete of the serious and difficult formation of this dip-coating method waste material in first base layer, the 101 immersion light modulation thing solution that formed accommodating layer 105 on it; ODF adopts drip, and light modulation thing 106 is accurately instiled in accommodating chamber 1051; Serigraphy is that light modulation thing 106 is evenly distributed on the equal liquid roller through doctor roll, thereby is imprinted on the APR version via equal liquid roller coat, and then is coated with and is imprinted on the accommodating layer 105.

When using medium of the present invention, earlier this medium is bent to required form, change the arrangement form of the smectic phase liquid crystal molecule in the light modulation thing 106 by being controlled at the driving pulse (being voltage signal) that applies on first, second conductive electrode layer 103,104 then, thereby medium is switched between the different light rays state, make medium of the present invention demonstrate required pattern.
The transparency electrode that is whole piece with first, second conductive electrode layer 103,104 is an example below, and the light modulation principle (is that 200810102000.7 Chinese invention patent application " electric-controlled light-regulating medium " is understood but referenced patent application number is 200710175959.9 Chinese invention patent application " a kind of electric-controlled light-regulating medium " and number of patent application) of flexible electronic control dimming medium of the present invention is described.
By drives control device output control voltage, on first, second conductive electrode layer 103,104, apply the driving pulse about 100v, 50Hz, when driving pulse action time the time less than 1 second, smectic phase liquid crystal molecule in the light modulation thing 106 (being the potpourri in the application for a patent for invention of institute's reference) just twists, and forms out of order arrangement form.Because each of smectic phase liquid crystal molecule (promptly passed through the long optical axis difference of each liquid crystal to diversity owing to incident ray, the anaclasis angle difference of each liquid crystal, thereby the refractive index difference of each liquid crystal), make the ray refraction of each smectic phase liquid crystal molecule of incident exist very big difference, promptly in the light modulation thing 106 of this meagre thickness, optical index is producing violent variation, thereby strong scattering has taken place in light in accommodating chamber 1051, on macroscopic view, the medium of the present invention of this moment is a kind of astigmatic effect, present vaporific shading state, as acute-matte.
By drives control device output control voltage, first, second conductive electrode layer 103, apply 100v on 104, driving pulse about 1kHz, when driving pulse action time the time less than 1 second, smectic phase liquid crystal molecule in the light modulation thing 106 just becomes regularly arranged form, at this moment, the long optical axis of smectic phase liquid crystal molecule is perpendicular to first, second conductive electrode layer 103,104 plane, the ray refraction of each smectic phase liquid crystal molecule of incident does not produce acute variation, light can freely see through light modulation thing 106, therefore, on macroscopic view, this moment, medium of the present invention presented the bright state of full impregnated.
After producing luminous effects such as scattering, full impregnated be bright for first, second conductive electrode layer 103,104 load driver pulses, medium of the present invention, just can remove voltage.The maintenance of this luminous effect does not need voltage to keep, promptly remove voltage after, the luminous effect that medium of the present invention produces in the time of still can keeping on-load voltage, and the voltage signal of effect is just in order to change the arrangement form of smectic phase liquid crystal molecule.In the present invention, this state that does not need electricity to drive and keep luminous effect is called " multistable " or " quasistatic ".And this " multistable " is because the additive in the light modulation thing 106 has adopted the compound of band conductive characteristic, when electric signal is applied on first, second conductive electrode layer 103,104, ion in the compound of band conductive characteristic changes the generation to-and-fro movement according to electric potential difference, this motion can change the arrangement form of smectic phase liquid crystal molecule, and the smectic phase Liquid Crystal Molecules Alignment form after changing does not need the persistent movement of ion to keep, and is stable.
Certainly, be applied to the pulse of the driving pulse on first, second conductive electrode layer 103,104 to number, frequency, voltage magnitude or action time by reasonable control, can make the arrangement form of smectic phase liquid crystal molecule become the part distortion, to produce astigmatic effect in various degree, thereby on macroscopic view, make medium of the present invention between bright two states of vaporific shading and full impregnated, produce multiple progressive state, as translucent etc. with different gray scales rank.
In addition, also can be mixed with dichroic dye in the light modulation thing 106, as flaxen azo group dichroic dye.By mixing dichroic dye, can make the switching between the bright and coloured shading of media implementation full impregnated of the present invention.
