For mixolimnion 103, the thickness of this mixolimnion 103 is micron order, and it can have two kinds of component composition forms.
The first component composition form is that mixolimnion 103 is mixed by smectic liquid crystal, conducting objects, spacer, blast thing.Smectic liquid crystal is category-A smectic liquid crystal, such as, with any one in silica-based compound, four cyano four octyl-biphenyl or tetraacethyl ester in last of the ten Heavenly stems four cyano biphenyl or several mixing.Conducting objects is the inorganic nano-particle of band conductive characteristic, carbon nano-tube, Graphene, sodium carbonate, cetyltriethylammonium bromide ethyltriphenylphosphiodide iodide phosphine, (ferrocenyl methyl) trimethyl ammonium iodide, 1,2-dimethyl-3-butyl imidazole hexafluorophosphate, tetraethyl amine p-toluenesulfonic acid ester, phenyl triethylammonium ammonium iodide, 1-octyl group-3-methylimidazole hexafluorophosphate, two (tetra-n-butyl amine) two (1,3-dithiole-2-thioketones-4,5-bis-mercaptan) palladium (II), tetra-n-butyl closes two (1,3-dithiole-2-thioketones-4,5-bis-mercaptan) nickel (III), two (tetra-n-butyl ammonium) closes two (1,3-dithiole-2-thioketones-4,5-bis-mercaptan) zinc, two (tetra-n-butyl ammonium) closes four cyano biphenol quinone bismethane, tetrabutyl ammonium bromide, cetyl ammonium perchlorate, cetyl bromination four ammonium, 1-butyl-3-methylimidazole tetrachloro ferrate, in methyl triphenyl phosphonium iodide or tetraphenylphosphoniiodide iodide phosphine any one or appoint several mixing.Spacer is the transparent batching sphere made of polyester material or polystyrene type macromolecular material or glass material or spacer rod.Transparent blast thing is high-refractive index particulate, and this high-refractive index particulate outer surface has charged material.The refractive index of high-refractive index particulate is greater than the refractive index of smectic liquid crystal, and the charged material of high-refractive index particulate outer surface is with positive charge or negative charge (this charged material is known technology, does not here describe in detail).High-refractive index particulate is by TiO
2, SiO
2, ZnO
2or Al

3in any one material make, the refractive index of these particulates be the 1.2-1.7 of the refractive index of smectic liquid crystal doubly.
Consisting of of the mixolimnion 103 of the first component composition form: smectic liquid crystal accounts for the 0.0002%-99.89% of mixing general assembly (TW), described conducting objects accounts for the 0.0001%-10% of mixing general assembly (TW), described spacer accounts for the 0.0001%-90% of mixing general assembly (TW), and described blast thing accounts for the 0.1%-1% of mixing general assembly (TW).Such as, this smectic liquid crystal can account for 99.89% of mixing general assembly (TW), and this conducting objects accounts for 0.0001% of mixing general assembly (TW), and spacer accounts for 0.0099% of mixing general assembly (TW), and blast thing accounts for 0.1% of mixing general assembly (TW).Again such as, this smectic liquid crystal can account for 0.0002% of mixing general assembly (TW), and this conducting objects accounts for 9.7998% of mixing general assembly (TW), and spacer accounts for 90% of mixing general assembly (TW), and blast thing accounts for 0.2% of mixing general assembly (TW).Again such as, this smectic liquid crystal can account for 89.4999% of mixing general assembly (TW), and this conducting objects accounts for 10% of mixing general assembly (TW), and spacer accounts for 0.0001% of mixing general assembly (TW), and blast thing accounts for 0.5% of mixing general assembly (TW).Again such as, this smectic liquid crystal can account for 15% of mixing general assembly (TW), and this conducting objects accounts for 7% of mixing general assembly (TW), and spacer accounts for 77% of mixing general assembly (TW), and blast thing accounts for 1% of mixing general assembly (TW).Again such as, preferably, this smectic liquid crystal can account for 80% of mixing general assembly (TW), and this conducting objects accounts for 7% of mixing general assembly (TW), and spacer accounts for 12.2% of mixing general assembly (TW), and blast thing accounts for 0.8% of mixing general assembly (TW).
For the mixolimnion of the first component composition form: conducting objects 1032 mainly increases the electric conductivity of mixolimnion 103, under voltage effect, conducting objects is changed the arrangement form of smectic liquid crystal molecule 1 031 by driving generation motion, thus change the photoelectric properties of smectic liquid crystal, so the consumption of conducting objects should be appropriate.If the ratio that conducting objects accounts for mixing general assembly (TW) is less than 0.0001%, then due to conducting objects very little, ion in conducting objects cannot change the arrangement form of smectic liquid crystal molecule according to the to-and-fro movement that electric potential difference change between row-column electrode produces, i.e. the color display of uncontrollable pixel.If the ratio that this conducting objects accounts for mixing general assembly (TW) is greater than 10%, then between first and second conductive electrode layer by likely because a large amount of conducting objects and short circuit, cannot to drive, meanwhile, a large amount of conducting objects can make the resistivity of mixolimnion 103 reduce, and have impact on its serviceable life.Spacer is passive, is used for controlling the thickness of mixolimnion 103.In actual applications, the consumption of spacer is less is advisable, as long as can reach the effect controlling mixolimnion 103 thickness.Namely the diameter of spacer is the thickness of mixolimnion, and the quantity of spacer suitably should be determined according to the mixolimnion thickness reached in advance and the selection adopting ball or rod.When smectic liquid crystal molecule is regularly arranged, because the optical refractive index of spacer is very close with the optical refractive index of smectic liquid crystal molecule, so spacer can not affect the transmittance of light, the optical properties of smectic liquid crystal molecule can not be affected, and spacer also can not affect astigmatism of the present invention and " multistable " characteristic.The refractive index ratio smectic liquid crystal of blast thing 1033 is much larger, when the out of order arrangement of smectic liquid crystal molecule, it is driven to side, be used for increasing the light-dispersing effect of corresponding mixolimnion 103 part, but when smectic liquid crystal molecule is regularly arranged, is distributed in corresponding mixolimnion part its general uniform, the transmittance of light can not be affected, can ignore the lifting of the light-dispersing effect of corresponding mixolimnion part, so the consumption of blast thing should be appropriate.If the ratio that blast thing accounts for mixing general assembly (TW) is less than 0.1%, then cannot reach the effect strengthening astigmatism.If the ratio that blast thing accounts for mixing general assembly (TW) is greater than 1%, then human eye can see blast thing, and blast thing can form precipitation, have impact on display effect.And smectic liquid crystal plays light modulation, image display effect, therefore, in actual applications, the consumption of smectic liquid crystal is more is advisable.
The second component composition form is that mixolimnion 103 comprises the potpourri being encapsulated in and being made up of smectic liquid crystal, conducting objects, spacer and blast thing in polymer architecture.Smectic liquid crystal is category-A smectic liquid crystal, such as, with any one in silica-based compound, four cyano four octyl-biphenyl or tetraacethyl ester in last of the ten Heavenly stems four cyano biphenyl or several mixing.Conducting objects 1032 is the inorganic nano-particle of band conductive characteristic, carbon nano-tube, Graphene, sodium carbonate, cetyltriethylammonium bromide ethyltriphenylphosphiodide iodide phosphine, (ferrocenyl methyl) trimethyl ammonium iodide, 1,2-dimethyl-3-butyl imidazole hexafluorophosphate, tetraethyl amine p-toluenesulfonic acid ester, phenyl triethylammonium ammonium iodide, 1-octyl group-3-methylimidazole hexafluorophosphate, two (tetra-n-butyl amine) two (1,3-dithiole-2-thioketones-4,5-bis-mercaptan) palladium (II), tetra-n-butyl closes two (1,3-dithiole-2-thioketones-4,5-bis-mercaptan) nickel (III), two (tetra-n-butyl ammonium) closes two (1,3-dithiole-2-thioketones-4,5-bis-mercaptan) zinc, two (tetra-n-butyl ammonium) closes four cyano biphenol quinone bismethane, tetrabutyl ammonium bromide, cetyl ammonium perchlorate, cetyl bromination four ammonium, 1-butyl-3-methylimidazole tetrachloro ferrate, in methyl triphenyl phosphonium iodide or tetraphenylphosphoniiodide iodide phosphine any one or appoint several mixing.Spacer is the transparent batching sphere made of polyester material or polystyrene type macromolecular material or glass material or spacer rod.Polymer architecture is transparent, it gets ready at equivalent layer (such as by single molecular material or (thermoplasticity) polymerizable molecular material by direct printing or etching or nano impression or spraying, first and/or second conductive electrode layer) medial surface on, heat curing or ultra-violet curing are that the polymerizable molecular material with setting structure is formed, and this single molecular material is any one in epoxy resin, polyacrylate or polymethacrylate monomer.This polymer architecture is formed with the accommodating chamber of the potpourri holding smectic liquid crystal, conducting objects, spacer and blast thing composition, polymer architecture can be rule spherical, micro-cylindric, thread, hemispherical, parallel strip, cube, rectangular parallelepiped, intersection are traditional thread binding, any one in the mixed structure of network structure (as hexagon cellular wall construction), square grid minor structure, irregular polygon structure or above-mentioned various structures, this polymer architecture can be uniform, may also be uneven.This polymer architecture and smectic liquid crystal, conducting objects, between spacer and blast thing can be mutually miscible, disperse, contact with each other or interval etc.Transparent blast thing is high-refractive index particulate, and this high-refractive index particulate outer surface has charged material.The refractive index of high-refractive index particulate is greater than the refractive index of smectic liquid crystal, and the charged material of high-refractive index particulate outer surface is with positive charge or negative charge.High-refractive index particulate is by TiO

Consisting of of the mixolimnion of the second component composition form: smectic liquid crystal accounts for the 0.0002%-99.89% of mixing general assembly (TW), polymerizable molecular material accounts for the 0.0001%-80% of mixing general assembly (TW), conducting objects accounts for the 0.0001%-10% of mixing general assembly (TW), spacer accounts for the 0.0001%-80% of mixing general assembly (TW), and blast thing accounts for the 0.1%-1% of mixing general assembly (TW).Such as, smectic liquid crystal accounts for 99.89% of mixing general assembly (TW), and polymerizable molecular material accounts for 0.0098% of mixing general assembly (TW), and conducting objects accounts for 0.0001% of mixing general assembly (TW), and spacer accounts for 0.0001% of mixing general assembly (TW), and blast thing accounts for 0.1% of mixing general assembly (TW).Again such as, smectic liquid crystal accounts for 0.0002% of mixing general assembly (TW), and polymerizable molecular material accounts for 45% of mixing general assembly (TW), and conducting objects accounts for 9.8998% of mixing general assembly (TW), and spacer accounts for 45% of mixing general assembly (TW), and blast thing accounts for 0.1% of mixing general assembly (TW).Again such as, smectic liquid crystal accounts for 15% of mixing general assembly (TW), and polymerizable molecular material accounts for 80% of mixing general assembly (TW), and conducting objects accounts for 2.5% of mixing general assembly (TW), and spacer accounts for 2% of mixing general assembly (TW), and blast thing accounts for 0.5% of mixing general assembly (TW).Again such as, smectic liquid crystal accounts for 84% of mixing general assembly (TW), and polymerizable molecular material accounts for 0.0001% of mixing general assembly (TW), and conducting objects accounts for 10% of mixing general assembly (TW), and spacer accounts for 4.9999% of mixing general assembly (TW), and blast thing accounts for 1% of mixing general assembly (TW).Again such as, smectic liquid crystal accounts for 14.2% of mixing general assembly (TW), and polymerizable molecular material accounts for 3% of mixing general assembly (TW), and conducting objects accounts for 2% of mixing general assembly (TW), and spacer accounts for 80% of mixing general assembly (TW), and blast thing accounts for 0.8% of mixing general assembly (TW).Again such as, smectic liquid crystal accounts for 55% of mixing general assembly (TW), and polymerizable molecular material accounts for 29.7% of mixing general assembly (TW), and conducting objects accounts for 5% of mixing general assembly (TW), and spacer accounts for 10% of mixing general assembly (TW), and blast thing accounts for 0.3% of mixing general assembly (TW).
For the mixolimnion of the second component composition form: conducting objects 1032 mainly increases the electric conductivity of mixolimnion 103, under voltage effect, conducting objects is changed the arrangement form of smectic liquid crystal molecule 1 031 by driving generation motion, thus change the photoelectric properties of smectic liquid crystal, so the consumption of conducting objects should be appropriate.If the ratio that conducting objects accounts for mixing general assembly (TW) is less than 0.0001%, then due to conducting objects very little, ion in conducting objects cannot change the arrangement form of smectic liquid crystal molecule according to the to-and-fro movement that electric potential difference change between row-column electrode produces, i.e. the color display of uncontrollable pixel.If the ratio that this conducting objects accounts for mixing general assembly (TW) is greater than 10%, then between first and second conductive electrode layer by likely because a large amount of conducting objects and short circuit, cannot to drive, meanwhile, a large amount of conducting objects can make the resistivity of mixolimnion 103 reduce, and have impact on its serviceable life.Spacer is passive, is used for controlling the thickness of mixolimnion 103.In actual applications, the consumption of spacer is less is advisable, as long as can reach the effect controlling mixolimnion 103 thickness.Namely the diameter of spacer is the thickness of mixolimnion, and the quantity of spacer suitably should be determined according to the mixolimnion thickness reached in advance and the selection adopting ball or rod.When smectic liquid crystal molecule is regularly arranged, because the optical refractive index of spacer is very close with the optical refractive index of smectic liquid crystal molecule, so spacer can not affect the transmittance of light, the optical properties of smectic liquid crystal molecule can not be affected, and spacer also can not affect astigmatism of the present invention and " multistable " characteristic.Polymer architecture bonds and supports two base layer effects.In mixolimnion 103, when smectic liquid crystal molecule is regularly arranged, because the optical refractive index of polymerizable molecular is very close with the optical refractive index of smectic liquid crystal molecule, so polymerizable molecular can not affect the transmittance of light, the optical properties of smectic liquid crystal molecule can not be affected, namely dimming capability (referring to transmittancy and astigmatism power) can not be affected, when the irregular alignment of smectic liquid crystal molecule, light can not be formed because the optical refractive index in the molecular axis both direction of smectic liquid crystal molecule itself is different transmitted through mixolimnion 103, have nothing to do with polymerizable molecular.And " multistable " of the present invention characteristic is the attribute of smectic liquid crystal molecule, have nothing to do with polymerizable molecular.But polymerizable molecular material is more, for image display area shared by overall ratio less, display effect will be deteriorated naturally.Therefore, in actual applications, the consumption of polymerizable molecular material is advisable in right amount, can not be too many.The refractive index ratio smectic liquid crystal of blast thing 1033 is much larger, when the out of order arrangement of smectic liquid crystal molecule, it is driven to side, be used for increasing the light-dispersing effect of corresponding mixolimnion 103 part, but when smectic liquid crystal molecule is regularly arranged, is distributed in corresponding mixolimnion part its general uniform, the transmittance of light can not be affected, can ignore the lifting of the light-dispersing effect of corresponding mixolimnion part, so the consumption of blast thing should be appropriate.If the ratio that blast thing accounts for mixing general assembly (TW) is less than 0.1%, then cannot reach the effect strengthening astigmatism.If the ratio that blast thing accounts for mixing general assembly (TW) is greater than 1%, then human eye can see blast thing, and blast thing can form precipitation, have impact on display effect.And smectic liquid crystal plays light modulation, image display effect, therefore, in actual applications, the consumption of smectic liquid crystal is more is advisable.
Below to arrange two floating control electrode layers, floating control electrode layer has the second structural form and has the display screen of the present invention (identical with the image displaying principle of the display screen with the second component composition form) of M × N standard of the mixolimnion of the first component composition form, and image display process of the present invention and principle are described.
First, initialization operation is carried out to display screen of the present invention, initialization operation be by smectic phase LCDs show piclear, to full frame carry out consistent initialization operation after display screen can be in full frame vaporific lucifuge (frosted) state.
Then, display screen is lined by line scan driving (also can adopt other order turntable driving, such as backward, random etc., belong to known technology).When turntable driving a line, by applying relevant voltage signal on column electrode corresponding to this row and each row electrode, each pixel on this row is made to become required display state (as all-transparent state, vaporific lucifuge state).After all line scannings drive, each pixel on display screen all becomes required display state.
Finally, with previous step line by line scan drive similar, electrode 1061,1071 on two floating control electrode layers 106,107 is driven (electrode 1061 on floating control electrode layer 106 can be regarded as " OK ", and the electrode 1071 on floating control electrode layer 107 can be regarded as " row ") line by line.When driving a line, by applying relevant voltage signal (this voltage signal can not make the arrangement form of smectic liquid crystal molecule change) on electrode 1061 corresponding to this row and each electrode 1071, floating control is carried out in the position of blast thing that just can be corresponding to each pixel on this row, the brightness of the pixel keeping vaporific lucifuge state is strengthened, and (reality slightly strengthens to drive the brightness for the pixel of all-transparent state to remain unchanged, can ignore, think substantially constant), thus strengthen the contrast between different colours pixel.After all row cutting are complete, the brightness of each pixel on display screen just adjusts complete, and display screen carries out image display with high-contrast effect.
For a pixel:
As Fig. 7, if this pixel will present vaporific lucifuge state (namely keeping the state after initialization), then first on a column electrode 1041, row electrode 1051 that this pixel is corresponding, apply relevant voltage signal (such as by Drive and Control Circuit, column electrode 1041, row electrode 1051 apply the positive and negative two-way hf and hv pulse of phase place identical about 100V, 1KHz, the voltage magnitude of the voltage waveform formed after the hf and hv pulse superposition that row-column electrode applies is 0, is less than threshold voltage magnitude.Threshold voltage is the magnitude of voltage changed for making smectic liquid crystal molecule that arrangement form be occurred by driving, and it is determined according to the composition of mixolimnion and thickness, is generally more than 5V.), conducting objects 1032 is not moved, and the out of order arrangement form of the smectic liquid crystal molecule 1 031 in mixolimnion 103 part that this pixel is corresponding does not change, and keeps the vaporific lucifuge state after original initialization, under the setting off of black backboard 110, this pixel is externally rendered as white.Afterwards, (this voltage signal can not make the arrangement form of smectic liquid crystal molecule 1 031 change on the electrode 1061,1071 that this pixel is corresponding, to apply relevant voltage signal by Drive and Control Circuit.Such as, electrode 1061,1071 applies respectively the voltage signal of+20V ,-20V), electronegative blast thing 1033 in mixolimnion 103 part that this pixel is corresponding is floated and gathers electrode 1061 side (to float and gather electrode 1071 side and be also fine, the object highlighted can be reached equally), the reflection of the light incided in this pixel corresponding mixolimnion 103 part and refraction number of times are increased greatly, thus promote astigmatism, strengthen the brightness of this pixel.
As Fig. 8, if this pixel will present all-transparent state, then first by Drive and Control Circuit at a column electrode 1141 corresponding to this pixel, a row electrode 1151 applies relevant voltage signal (such as, column electrode 1041, row electrode 1051 applies the 100V that phase place is contrary, the positive and negative two-way hf and hv pulse of about 1KHz, the voltage magnitude of the voltage waveform formed after the hf and hv pulse superposition that row-column electrode applies is 200V, be greater than threshold voltage magnitude), when voltage action time is less than 1 second, the motion of conducting objects 1032 just makes the smectic liquid crystal molecule 1 031 in mixolimnion 103 part that this pixel is corresponding become regularly arranged form, now, the long optical axis of smectic liquid crystal molecule 1 031 is perpendicular to first, second conductive electrode layer 104, 105 planes, the refraction of the light of incident each smectic liquid crystal molecule 1 031 does not produce acute variation, incident light can freely through this mixolimnion 103 part, present all-transparent state, under the setting off of black backboard 110, most of light completely transmitted through this mixolimnion 103 part is absorbed by black backboard 110, this pixel is externally rendered as black.Afterwards, by Drive and Control Circuit do not apply on the electrode 1061,1071 that this pixel is corresponding voltage signal (or, an electrode applies voltage signal wherein and another does not apply voltage signal, the applying of this voltage signal can not make the arrangement form of smectic liquid crystal molecule 1 031 change.), the general uniform in mixolimnion part of the electronegative blast thing 1033 in mixolimnion 103 part that this pixel is corresponding is distributed, and (if initial blast thing is evenly distributed in mixolimnion part, then this operation makes blast thing maintain the original state.If initial blast thing is gathered in certain side, then this operation makes blast thing turn back to also general uniform distribution in mixolimnion part), the blast thing be evenly distributed in mixolimnion part can not have too large lifting to astigmatism, can ignore, thus, the brightness of this pixel can not be enhanced.Just because of this, the contrast effect between this black pixel point that brightness is constant and the white pixel point that brightness strengthens enhances.
Certainly, by the voltage signal (if amplitude size, frequency, pulse are to number and action time etc.) on the row, column electrode that a certain pixel of conservative control is corresponding, the arrangement form of the smectic liquid crystal molecule in mixolimnion part corresponding to this pixel also can be made to become part distortion, to produce astigmatism effect in various degree, macro manifestations is produce the multiple progressive state with different gray scale rank between vaporific lucifuge state and all-transparent state two states, as translucent etc., this pixel is made to present the color of different gray scale.Correspondingly, according to the display needs of different gray-scale pixels point, by carrying out the brightness of corresponding enhancing pixel to the control of blast thing.
It should be noted that in the present invention, the control that the control of smectic liquid crystal molecules align form and blast thing fluctuate successively carries out.When giving each electrode on-load voltage signal of first, second conductive electrode layer 104,105 and after pixel changed by driving, just can removing the voltage signal of applying.And the maintenance of this luminous effect of pixel does not need voltage signal to maintain, namely after removing voltage signal, pixel still can keep the luminous effect produced during on-load voltage signal, and the arrangement form of the voltage signal of effect just in order to drive conducting objects 1032 to change smectic liquid crystal molecule 1 031.In the present invention, electric drive is not needed and the state maintaining luminous effect is called " multistable " or " quasistatic " by this.And this " multistable " is because with the addition of conducting objects in mixolimnion 103, when applying voltage signal, to-and-fro movement is produced according to electric potential difference change with the ion in the conducting objects of conductive characteristic, this motion can change the arrangement form of liquid crystal molecule, and the Liquid Crystal Molecules Alignment form after change does not need the persistent movement of ion to maintain, be stable.And the voltage signal applied when controlling blast thing thereafter can not produce any impact to the arrangement form of smectic liquid crystal molecule, the arrangement form of smectic liquid crystal molecule can not change.
For the display screen of the present invention with the second structural form, if only arrange a floating control electrode layer, then the control that together with the conductive electrode layer (the first or second conductive electrode layer 104 or 105) being arranged in different side, the blast thing 1033 of mixolimnion 103 fluctuated of this floating control electrode layer.Specifically, first each pixel is made to be shown as required state by the first conductive electrode layer 104 and the second conductive electrode layer 105, controlled by the blast thing that this floating control electrode layer is corresponding to each pixel with that conductive electrode layer corresponding more afterwards, thus make the brightness of each pixel reach default object.The image displaying principle of the display screen of the present invention of this kind of structural form is substantially identical with above-mentioned image displaying principle, does not here describe in detail.
Similarly, for the display screen of the present invention with the first structural form, the display state of a pixel is realized by the display sub-pixel point in this pixel, this display sub-pixel point is by going accordingly, row electrode controls, and the brightness of this pixel is realized by the blast sub-pixel point in this pixel, this blast sub-pixel o'clock controls (for arranging the display screen of two floating control electrode layers) by corresponding two electrodes on two floating control electrode layers or is controlled (for arranging the display screen of a floating control electrode layer) to the corresponding electrode on corresponding conductive electrode layer by the corresponding electrode on a floating control electrode layer.This image displaying principle with the display screen of the present invention of the first structural form is substantially identical with above-mentioned image displaying principle, does not here describe in detail.
In actual design, mixolimnion 103 also can be mixed with dichroic dye, preferably, dichroic dye can account for 5% of mixing general assembly (TW), by appropriate dichroic dye is mixed into mixolimnion 103, mixolimnion of the present invention can be made to realize all-transparent, coloured shading, the various switching had between color shade rank.The image displaying principle of the present invention being mixed with dichroic dye in mixolimnion 103 is substantially identical with the present invention not adding dichroic dye, therefore, no longer here describes in detail.
Advantage of the present invention is:
The blast thing added in mixolimnion of the present invention adds the refraction number of times of light in mixolimnion, add the order of reflection of light and backboard, when smectic liquid crystal molecule becomes out of order arrangement form, blast thing enhances the scattering strength of light, and when smectic liquid crystal molecule becomes regular arrangement form, blast thing can not affect the transmittance of light, and (scattering strength of light slightly improves because of blast thing, can ignore), thus the interpolation of blast thing greatly enhances the brightness (especially white pixel point) of light colour pixel, improve the contrast between the different colours pixels such as black and white, the sharpness of display screen is improved, and increase the visible angle of display screen.
Compared with existing smectic liquid crystal display screen, the brightness of display screen of the present invention improves about 1.2 times, contrast improves about 1.2-1.3 doubly, visible angle increases about 1.2-1.5 doubly, further, display screen of the present invention is radiationless, and energy consumption is low, cost is low, can be used as electronics stationery, commercial paper product uses.
The above-mentioned know-why being preferred embodiment of the present invention and using; for a person skilled in the art; when not deviating from the spirit and scope of the present invention; any based on apparent changes such as the equivalent transformation on technical solution of the present invention basis, simple replacements, all belong within scope.
