glass plates

21 and 22 around be added with sealed partition 25.

Image display controller system 30 has a magnetic field that is fixed on the outside surface of the glass plate 22 on the magnetic fluid display board 20 that substrate 31 takes place.

Substrate 31 takes place and comprises the first transparent pattern electrode 33 and the second transparent pattern electrode 34 in magnetic field, the former is installed on the limit of magnetic fluid display board 20 or on the front surface of glass 32, the latter then is installed in glass 32 rear surfaces, both installations all adopt one known as Fig. 4 to shown in meticulous operation finish.

First pattern electrode 33 comprises and a series ofly clearly shows like that the directions X public line electrode 331 that uniformly-spaced is provided with along directions X and a plurality ofly be provided with and from the electrode 331 spiral pattern electrodes 332 of extensions clockwise along above-mentioned directions X common electrode 331 as Fig. 5 and 7.Especially, clockwise the screw electrode 332 that extends is arranged along X and Y both direction, thereby forms a matrix, and wherein the distance between two of the spiral pattern electrode 332 adjacent centers is represented with pixel pitch P.

Second pattern electrode 34 comprises a series of Y direction common electrodes 341, and it extends with the center of arranging and pass spiral pattern electrode 332 like that along pixel pitch P ground such as Y directions shown in Fig. 6 and 7.

Glass plate 32 has a plurality of through holes 35, and each hole is passed the center of spiral pattern electrode 332 as illustrated in fig. 8 and extended.Conductive electrode 36 is filled in each of through hole 35, thereby the Y direction that makes the spiral pattern electrode 332 on top and bottom is with being electrically connected between the electrode 341.

As shown in Figure 4, an end of the directions X common electrode 331 of first pattern electrode 33 is connected to power supply 42 by the corresponding on-off element 411 of a directions X matrix switch 41.

In addition, an end of the Y direction common electrode 341 of second pattern electrode 34 is then as shown in Figure 4 by corresponding on-off element 431 ground connection of matrix switch 43 in the Y direction.First and

second pattern electrodes

33 and 34 whole circuit all are covered with transparent insulating layer.

Directions X and Y direction matrix switch 41 and 43 are suitable for responding from the clock signal of time schedule controller 45 and carry out the ON/OFF conversion.Say that more properly time schedule controller 45 determines a series of on/off operation of two matrix switches 41 and 43, activate with the pixel that makes some corresponding to a picture intelligence.

The function and the magnetic fluid display board among the embodiment 1 of the magnetic fluid display board among the embodiment 2 are roughly the same, but an advantage is arranged, and the generation in the magnetic field that Here it is is caused by a picture intelligence directly takes place for magnetic fluid 24.Therefore, bigger effect can take place to magnetic fluid 24 in the magnetic field of Chan Shenging like this, and the excitation of spiral pattern electrode 332 can be finished with less current simultaneously.

Embodiment 3

Figure 11 shows the 3rd routine allocation plan according to magnetic fluid display of the present invention.

As shown in the figure, the magnetic fluid display board 20 of magnetic fluid display 10 comprises the display box unit 70 that a plurality of cardinal principles are grid-like, and they interconnect and form a display screen.

In this scheme, display box unit 70 is divided into unit, angle 71, edge element 72 and unit, middle part 73; Unit, angle 71 has two adjacent edges to be made into straight line, and two limit 71a do waviness in addition, so that interconnected; Edge element 72 has the straight line limit, and three limit 72a do waviness in addition; The four edges 73a of unit 73, middle part does waviness so that interconnected, as shown in figure 11.

More specifically, the temporary location 73 of display box unit 70 is made up of a plurality of fritters 75 that are filled with magnetic fluid, and it is to be arranged in equidistantly in the aluminium box substrate 74, and pitch is P; As shown in figure 12.

The cross-section illustration of fritter 75 that is filled with magnetic fluid is in Figure 13.

As shown in the figure, box substrate 74 has the hole 751 of some to arrange with spacing (pitch is P).Radially strengthen district 752 on 751 front sides, hole have, it has the major diameter and the little degree of depth (its diameter is 3 millimeters in this programme); Hole 751 dorsal parts have radially to strengthen down distinguishes 753, and it has the bigger diameter (also being 3 mm dias) and the bigger degree of depth here.Hole 751 also be included in central authorities, the chamber 754 that is filled with magnetic fluid, the latter radially strengthens

district

752 and 753 by two and limits and have a less diameter (this programme is 2 millimeters), while very shallow (200 microns).

Imbed the color filter 755 that one of red, green, blue three primary colours light of permission sees through last radially the increasing in the district 752, the latter is fixed on the inwall of aperture 751 tightly.Then inlay a transparent glass sheet 756 tightly at the interior place that radially strengthens district 753 down.Magnetic fluid chamber 754 just just in time is encapsulated between color filter 755 and the glass sheet 756.

More specifically, after loading onto glass sheet 756, and do not adorn before the color filter 755, toward being full of the indoor filling magnetic fluid 24 of magnetic fluid.

In addition, the following inwall that radially strengthens district 753 in district 75 is equipped with a solenoid 80 with winding of some, thereby the mesopore 81 of solenoid 80 can make light pass through.

Solenoid 80 by from embodiment 1 in the image control signal excitation selectively of similar visual display control program, thereby in the thickness range of magnetic fluid display board 20, produce magnetic field, thereby the magnetic fluid 24 in the district that is filled with magnetic fluid 75 of excitation pixel.

More specifically, in case after having accepted the electric current of picture intelligence, solenoid 80 just produces a magnetic field, the latter passes the magnetic fluid 24 in the district 75 of magnetic fluid, makes the magnetic particle of magnetic fluid 24 be orientated along magnetic direction.

As a result, magnetic fluid 24 just changes the printing opacity attitude into from suspended state, and this is the same with embodiment 1, thereby allows light by district 75 or pixel.

If solenoid is energising not, the fluid zone 75 that magnetizes still keeps opaque attitude, and does not have light to see through.

So the combination of diaphanous spot on the magnetic fluid display board 20 and light tight point will constitute an images on magnetic fluid 24.

By the display unit 70(with predetermined number mainly is unit 71 and 73) couple together, just can be made into the display screen of desired size of the matrix of the capable and n row pixel of m.

Embodiment 4

Figure 14 is used for describing the 4th routine allocation plan proposed by the invention, and it has done modification to the magnetic fluid display board 20 of embodiment 3.

As shown in the figure, the magnetic fluid display board 20 after the variation is made by following steps, and these steps comprise: form a plurality of grooves 93 that are filled with magnetic fluid equally spacedly with pitch P on one of two blocks of

transparent rubber plates

91 and 92; Be joined together two blocks of

transparent rubber plates

91 and 92 and make groove 93 to be in inside; The pin 95 of syringe 94 and air guide pin 96 are inserted into each groove 93 by transparent rubber plate 91; And, by syringe 94 a certain amount of magnetic fluid 24 is charged into groove 93.In addition, load onto a solenoid 80 for each groove, identical in its effect and the example 3.

After having filled magnetic fluid 24 and having removed air guide nail, because the elasticity of rubber, pin hole on transparent rubber plate 91 and nail hole can be sealed, and magnetic fluid 24 is enclosed in the alcove and does not reveal.

Because the main assembling process of magnetic fluid display board 20 had just been finished before filling magnetic fluid 24, so the step of sealed groove 93 has just been omitted subsequently.Therefore improved the production efficiency of magnetic fluid display board 20.

In addition, the present invention will obtain as the image display control apparatus that is used for the magnetic fluid display describing.As shown in figure 15, image display control apparatus is contained in the back side of magnetic fluid display board 1, and plate 1 is made up of two transparent panels 2,2; Transparent panel separates with space 3 each other, magnetic fluid 4 just is filled in the space 3, wherein magnetic particle 4a evenly distributes and keeps stable, and produces magnetic field B by the image control signal of certain specific pixel in the thickness range of whole magnetic fluid display board 1, thereby activates magnetic fluid 4.More specifically, image display control apparatus of the present invention comprises that substrate 15 takes place in a magnetic field, and it mainly is made up of a plurality of magnetic fields genetic horizon 16.Each magnetic field genetic horizon 16 has a plurality of photic zones 7 corresponding with pixel, be arranged on the magnetic fluid display board 1 with equidistant pixel pitch, and layer 16 is equipped with two spiral electrode bars 9 on its two sides, and the latter is round photic zone 7.These spiral electrode bars 9 are by insulating coating 8 protections.Be electrically connected to each other by the hole 16a on magnetic field genetic horizon 16 at the spiral electrode bar 9 on the two sides.Any two direct spiral electrode bars 9 of contact between two magnetic field genetic horizons 16 by with electroconductive binder 11, contact the tail end of one of them, and couple together with head end at another.Like this, a series of spiral electrode bars 9 have constituted the multiturn coil 12 round photic zone 7, and extend on the thickness range of whole magnetic fluid generation substrate 15.Multiturn coil 12 comes excitation by image control signal, to activate pixel.

In such scheme, the magnetic particle 4a in magnetic fluid 4 can be selected from magnetic ferrites, iron oxide, nickel, molybdenum disulfide and other material.

4a is as far as possible little for magnetic particle, and evenly to be distributed and to keep stable, preferably diameter is between 0.001 to 10 micron.Magnetic particle 4a is the staple fibre slice preferably, and they can distinguish opaque and clear state.

For the magnetic particle 4a in the magnetic fluid 4 is evenly distributed and the maintenance suspended state, magnetic particle 4a and surfactant can be mixed by a certain percentage or are suspended in the suitable liquid (for example water), the effect of surfactant can make the magnetic particle 4a of high concentration stably be distributed in the magnetic fluid.

The distance in space 3 can equal the length of the magnetic particle 4a of delegation, and very good is diameter (being generally 0.5 millimeter to 2 millimeters) much larger than magnetic particle 4a, to guarantee the opacity of suspended state.

Magnetic fluid 4 on the magnetic fluid display board 1 can continuous distribution on the monoblock panel is long-pending, also can be divided into several cells.

At latter event, the magnetic fluid cell of given number is combined into, and corresponding with corresponding pixel, to constitute sliceable display unit.So, when the sliceable display unit of some is combined, then constitute the display screen of a large-size.

Substrate 15 takes place and can separate with magnetic fluid display board 1 in magnetic field, also can make an integral body with its transparent panel 2.

In the previous case, damage or lost efficacy if substrate 15 takes place in the magnetic field that separates with magnetic fluid display screen 1, can easily change one new, magnetic fluid display board 1 is kept intact, thereby improves mission life.

Under latter event, the transparent panel 2 of substrate 15 as magnetic fluid display board 1 takes place in magnetic field, directly be exposed to magnetic fluid 4, thereby magnetic fluid passed in its magnetic field more consumingly.This just can reduce the electric current to multiturn coil 12 excitations.

If magnetic field genetic horizon 16 itself is transparent, the photic zone 7 on the magnetic field genetic horizon 16 can directly use, if it is opaque, just need get through the light hole corresponding with pixel of some on magnetic field genetic horizon 16.Photic zone 7 can be made garden shape, square or any other suitable shape.When the pixel of magnetic fluid display board 1 is by filling when determining with the chamber of magnetic fluid, the shape of photic zone 7 should be consistent with the shape of the fluid chamber of magnetizing.

Spiral electrode bar 9 is not limited to the only photic zone 7-circle on magnetic field genetic horizon 16, and it can be two circles or multiturn more, as long as the space permission.

The electrically conducting adhesive 11 that is used for bonding a series of spiral electrode bars 9 can apply by the printing conductive inks material.In order to make technological process simple, electrically conducting adhesive 11 is hot melt materials, for example scolder.

In fact, preparation comprises that the step that substrate 15 takes place in the magnetic field of one group of magnetic field genetic horizon 16 comprises: form spiral electrode bar 9 around each photic zone 7 on magnetic field genetic horizon 16 and form hole on the limit; Heat-fusible materials electrically conducting adhesive 11 is coated on the side relative with the open sides of perforation 16a between per two adjacent spiral electrode bars 9; And, under certain pressure, one group of magnetic field genetic horizon 16 is heated to the uniform temperature that makes electrically conducting adhesive 11 fusings.

On the lead-in wire that the multiturn coil 12 corresponding with each pixel can be connected respectively to separately.In order to simplify the mode of connection, a plurality of multiturn coils 12 all are coupled on the concentric line 13.

Note that electric current adjustment element 14 is connected in series with multiturn coil 12 and concentric line 13, flows on the multiturn coil 12 from concentric line 13 to prevent current reversal ground.

Electric current is adjusted the preferably diode of clear glass encapsulation of element 14, and the latter is with respect to being provided with the photic zone 7 of nethermost magnetic field genetic horizon 16, to be convenient to be provided with circuit.A good practice is to make the diode of glass-encapsulated can be used as optical lens, makes light focusing on the corresponding pixel of magnetic fluid display board 1.

The process that preparation has the image display control apparatus of electric current adjustment element 14 may further comprise the steps: form the hole on spiral electrode bar 9 and next door around the photic zone everywhere 7 on magnetic field genetic horizon 16, the electrically conducting adhesive of simultaneously heat-fusible materials being made 11 is added on the side relative with the open sides of hole 16a between the adjacent spiral electrode bar 9; Under the situation of pressurization, one group of magnetic field genetic horizon 16 is heated to makes the required temperature of electrically conducting adhesive 11 fusing, extend on the thickness that substrate 15 takes place in whole magnetic field with formation, still the multiturn coil 12 that does not link to each other with concentric line 13; And adjust element 14 with electric current the multiturn coil 12 that magnetic field takes place in the substrate 15 is coupled together with concentric line 13.

When work, image display control apparatus is carried out control action, and with under the control of image control signal, decision produces or do not produce the magnetic field of passing the corresponding pixel on the magnetic fluid display board 1.More specifically, it changes the orientation (becoming light tight or pellucidity) of the magnetic particle 4a of the magnetic fluid 4 of each pixel on the magnetic fluid display board 1, so that light is by some pixel (see figure 2) that ascertains the number.

Take place in the substrate 15 in the magnetic field of the magnetic field genetic horizon 16 that comprises some, each multiturn coil 12 that is used to produce the magnetic field of passing pixel is made of a series of spiral electrode bars 9, these electrode strips are contained on two faces of each magnetic field genetic horizon 16, and are joined to one another by perforation 16a on these layers 16 and by directly using electrically conducting adhesive.Therefore, produce the magnetic field B that is used for pixel effectively by multiturn coil 12, and coil 12 is provided with the current i of image control signal, thereby has been activated the magnetic fluid 24 of the pixel of magnetic fluid display board 1.

Because one group of multiturn coil 12 and concentric line 13 by they separately, the electric current that is provided with of connecting adjusts that element 14 couples together, it has stoped the inverse current that flows to multiturn coil 12 from concentric line.

151 and 152 are closely combined; Passing rubber slab 151 injects respectively during the syringe needle of syringe and air guide nail magnetize fluid alcove 153 to each; And, because the effect magnetic fluid 153 of syringe fills into magnetic fluid alcove 154.

Especially, magnetize about 1.5 millimeters of the degree of depth of alcove 154 of fluid.Magnetic fluid 154 is potpourris of the magnetic particle 154a that does of surfactant (for example, fatty acid solution soap) and Ferrite Material, and magnetic-particle 154a makes pellets (staple fibre shape), 0.001 micron of diameter, and length is 0.1 micron.Both mix by proper proportion.

The multiturn coil 161 that substrate 134 is useful on each pixel takes place in magnetic field, as shown in figure 21.The row of the multiturn coil of arranging along directions X 161 are connected respectively on the power supply 166 to each on-off element 165a on the matrix switch 165 by X.The Y that worked of the multiturn coil of arranging along the Y direction 161 is to the on-off element 167a of matrix switch 167 ground connection respectively.

Multiturn coil 161 interrelates with diode 162, and the latter links to each other with concentric line, and concentric line ground connection, and electric current can only flow to concentric line from multiturn coil.

X is to the ON/OFF effect to matrix switch 165 and 167 is to be controlled by the clock signal of time schedule controller 168 with Y.The clock signal of time schedule controller 168 is determined by picture intelligence, and is distributed to the pixel of magnetic fluid display board 133.

Now the structure to magnetic field generation substrate 134 is described in detail.

Shown in Figure 22-24, substrate 134 takes place and comprises that 6 magnetic field genetic horizon 170(are labeled as #1 to #6 in magnetic field), they stack mutually.For the purpose of illustrating, the X among Figure 22-24 is decided to be 15 to number of picture elements, and Y is 16 to number of picture elements.

Figure 22 (a) and 22(b) the signal first magnetic field genetic horizon 170(#1 that drawn respectively) forward sight and rear view.

Magnetic field genetic horizon 170(#1) be to be done by the transparent resin material that contains some garden shape photic zones 171, photic zone is assigned to pixel.

Shown in Figure 22 (a), some spiral fashion electroplax bars 172 that shape almost resembles whole garden are configured in magnetic field genetic horizon 170(#1 respectively) the photic zone 171 of front around.Though at each spiral electrode bar 172(that lists not is line spread, but the half pitch that staggers each other links together by line 173 as shown in the figure).And 172 row of the spiral electrode bar of arranging along directions X respectively by lead-in wire 174 be connected to X to lead end 175, the latter further with X to matrix switch 165 link to each other (seeing Figure 21).

Similarly, at magnetic field genetic horizon 170(#1) the back side on photic zone 171 around, be respectively arranged with almost some spiral electrode bars 176 configurations of garden shape, shown in Figure 22 (b).

The lead end of the spiral electrode bar 172 of front is by magnetic field genetic horizon 170(#1) perforation 177 link to each other with an end of the back side spiral electrode bar 176 of each photic zone 171.The other end of back side spiral electrode bar 176 at perforation 177 places does not have a solder joint 178.

The hand work preparation that spiral

electrode bar

172 and 176 usefulness are known.Electrode strip 172,176, line 173, and go between and 174 all use protective finish (perhaps insulation course) 179 to protect, except the solder joint part 178, (seeing Figure 26).

Figure 23 (a) and 23(b) be second magnetic field genetic horizon 170(#2) forward sight and the synoptic diagram of backsight.

Similarly, magnetic field genetic horizon 170(#2) do by transparent resin material, have the garden shape photic zone 171 corresponding with pixel.

Shown in Figure 23 (a), almost some spiral electrode bars 172 of garden shape are separately positioned on this magnetic field genetic horizon 170(#2) front surface on photic zone 171 around.Similarly, the approximate spiral electrode bar 176 in some shapes and garden is separately positioned on this magnetic field genetic horizon 170(#2) the lip-deep photic zone 171 of the back of the body around, shown in Figure 23 (b).

The terminal of the spiral electrode bar 172 on the front surface is by this magnetic field genetic horizon 170(#2) on perforation 177 link to each other with the top point of the back of the body surface spiral electrode bar 176 of this photic zone 171.The top of front surface electrode bar 172 is linked to each other by solder joint with the terminal of back of the body surface electrode bar 176.

The known careful technology of

spiral electrode bar

172 and 176 usefulness prepares, and protects with protective finish (or insulation course) 179, but (sees Figure 26) except the welding portion.The magnetic field genetic horizon 170(#3-#5 that tightly joins) structurally with previous 170(#2) be the same haply, just spiral

electrode bar

172 and 176 direction slight change.

Figure 24 (a) and 24(b) be respectively last a kind of magnetic field genetic horizon 170(#6) forward sight and the synoptic diagram of backsight.

Magnetic field genetic horizon 170(#6) the same with (#1), the garden shape photic zone 171 of some is distributed to pixel.

Shown in Figure 24 (a), the spiral electrode bar 172 that some shapes are close to garden shape is configured in magnetic field genetic horizon 170(#6 respectively) front surface on photic zone 171 around.

Similarly, some spiral electrode bars 176 that are close to garden shape are set at magnetic field genetic horizon 170(#6 respectively) the lip-deep photic zone 171 of the back of the body around, shown in Figure 24 (b).Spiral electrode bar 176 on each row is connected to each other by line 180.The row spiral electrode bar of arranging along the Y direction 176 by lead-in wire 181(at this magnetic field genetic horizon 170(#6) forward and backward two surfaces go up extend) be connected respectively to Y to terminal 182, the latter further is connected to matrix switch 167 with Y, (seeing Figure 21).The terminal of front surface electrode bar 172 is by magnetic field genetic horizon 170(#6) on perforation 177 link to each other with an end of the electrode strip 176 on back of the body surface.The top of front surface electrode bar 172 has solder joint 178.Shown in this programme, one section of the back of the body surface electrode bar 176 of this last one deck will be removed, so that disconnect (seeing Figure 25).

Spiral electrode bar

172 and 176 adopts known technology preparation, and protects with protective seam (or insulation course) 179, but except the solder joint part (Figure 26).

Mark is that 183 part is a pilot hole among Figure 22 and 24, is positioned on four angles of every magnetic field genetic horizon 170, to determine the position of these magnetic field genetic horizons 170 when assembling.

At magnetic field genetic horizon 170(#1-#6) these spiral electrode bars 172 and 176 between positioning relation be shown in Figure 25 and 26.

Draw each magnetic field of Figure 25 produces a layer 170(#1-#6) spiral electrode bar 172 and 176 top view.The front surface electrode bar 172 of ground floor (#1) links to each other with top with the back of the body surface electrode bar 176 of one deck by through hole 177.The terminal of back of the body surface electrode bar 176 is by part that abutment A(solder joint 178 adds) link to each other with the top of the front surface electrode bar 172 of second layer #2, the latter passes through through hole 177 successively and links to each other with its back of the body surface electrode bar 176.Then, the terminal of the back of the body surface electrode bar 176 of second layer #2 has solder joint 178 by abutment B() be connected with the top of the 3rd layer front surface electrode bar 172, thereby continue again to be connected with its back of the body surface electrode bar 176.The back of the body surface electrode bar 176 of the 3rd layer of #3 has solder joint 178 by abutment C() be connected with the forward and backward electrode strip 172,176 of the 4th layer of #4, the latter has solder joint 178 by abutment D(again) link to each other with 176 with two surface electrode bars 172 of layer 5 #5.The spiral electrode bar 172 and 176 of layer 5 #5 has solder joint 178 by contact E(again) and layer 6, also be that the electrode strip of last one deck #6 links to each other.

According to this scheme, all these spiral electrode bars 172 and 176 can couple together as follows: under certain pressure six magnetic field genetic horizon 170(#1-#6) be stacked together, and heat a period of time making under the required temperature of solder joint 178 fusing, so that this six layer 170 be soldered at the A-E point respectively by solder joint 178, as shown in figure 27.

As a result, these six magnetic field genetic horizons 170 have become magnetic field substrate 134 have taken place, and these electrode strips 172 and 176 form one 12 coil 161 together simultaneously.

In embodiment 5, be used as diode 162, this former introduction with the diode of clear glass sealing-in.When magnetic field generation substrate 134 assembled up by the mode of narrating above, multiturn coil 161 did not have diode 161, as shown in figure 28.After the assembling of layer is finished, diode 162 is coupled together with their multiturn coils 161 separately by bonding 190, as shown in figure 29.

After these diodes 162 and their multiturn coils 161 separately are together in series, as shown in figure 30, they just prevented electric current from the concentric line reverse direction flow to multiturn coil 161, as shown in figure 30.In Figure 25-31, Xo represents the value of Building X mark and Building Y punctuate respectively to Yn to Xm and Yo.

Especially, diode 162 is placed on the photic zone that substrate 134 takes place in magnetic field, and makes it and last piece magnetic field genetic horizon 170(#6) the broken string place 180 of back of the body surface spiral electrode bar 176 be electrically connected, shown in Figure 25 and 31.

So transparent diode 162 can not prevent that light from passing magnetic field substrate 134 takes place.

The work of magnetic fluid display will be introduced below among the embodiment 5.

After receiving image control signal, time schedule controller 168 control X to the ON/OFF of Y to matrix switch 165 and 167.

Suppose that for certain particular pixels its image control signal is " 0 ", then X is to opening to two the corresponding on-off element 165a and the 167a of matrix switch 165 and 167 with Y.So, there is not electric current to flow through the multiturn coil 161 at this pixel place, just there is not the magnetic field deactivation to be filled in the magnetic fluid 154 of pixel area G, so the latter still remains on the OFF state, shown in figure 32 yet.

Because the magnetic particle 154a in the regional G still is suspended in stable dispersed, magnetic fluid 154 is exactly opaque, does not allow light transmission.

When the image control signal of pixel is " 1 ", the X corresponding with this pixel is to just closed to the on-off element 165a and the 167a of matrix switch 165,167 with Y, the multiturn coil 161 of this pixel just has electric current to flow through, thereby the generation magnetic field B is passed the magnetic fluid 154 among the area G, thereby transfer the ON attitude to, shown in figure 32.

As a result, be in the magnetic particle 154a ON attitude, the magnetic fluid in regional G 154 along magnetic field B direction orientation, so light 100 is passed through.

The combination in photic zone and resistance light district on the magnetic fluid display board 133, thus constitute the picture pattern of a width of cloth magnetic fluid.

Embodiment 6

Figure 33 and 34 describes another magnetic fluid display exemplary scheme that the present invention proposes.On the magnetic fluid display board 201 location-plate 206 is housed herein, location-plate 206 is used for controlling flow direction.

As shown in the figure, magnetic fluid display board 201 comprises substrate 202, and substrate 208 takes place for package board 205 and magnetic field, and they are all made by transparent glass material substantially.Substrate 202 has inlayed a plurality of magnetic fluid filled chambers 203, and they press the equidistant arrangement of pixel pitch.Magnetic current body cavity 203 is marked with the magnetic fluid 211 that comprises magnetic particle 211 and is sealed in package board 205 and magnetic field takes place between the substrate 208.Blacking enamelled coating 204 is inserted in magnetizing between the fluid cavity 203 of any two vicinities on the substrate 202, with against sunshine from boundary leakage.

Magnetic field take place substrate 208 contain with substrate 202 on the multiturn coil 209 of cavity 203 corresponding numbers, their modes similar to Figure 22 to 27 are arranged.The magnetic fluid display board 201 tops plate 209 that is positioned fully is topped; Location-plate 209 is made by ferromagnetic material, such as Cobal(Westinghouse house mark name), it is Fe, Ni, Co alloy.Location-plate 206 also has the shape hole, garden 207 that ascertains the number, and the position in hole 207 is corresponding with 203 positions, chamber on the substrate 202.

In this kind scheme, location-plate 206 thickness are 0.5mm, and package board 205 thickness are 0.25mm, and substrate is thick to be 0.25mm, and substrate 208 takes place in magnetic field is 0.2mm.The thickness of location-plate 206 and package board 208 is preferably as far as possible little, and for example location-plate 206 is 0.1 to 0.5mm, and package board 205 is 0.1 to 0.25mm.The diameter in the shape hole, garden 207 on the location-plate 206 is 0.45mm.

During work, when magnetic field is produced by the multiturn coil 209 that passes to electric current, its magnetic line of force 215, (marking with solid line in Figure 34) be because the existence of location-plate 206, and possible magnetic line of force 214(marks with dotted line during than no location-plate by substrate 202 thickness the time) much straight.So, the magnetic line of force 215 make magnetic particle 211 in the chamber 203 along the Width of substrate 202 by desirable line spread.Particularly, as be among Figure 34 the ON attitude 212 shown in, 211 one-tenth of magnetic particles are vertically arranged along stretching line, provide the transparency range of broad.Therefore the transmitance of light will increase.In addition, the magnetization of multiturn coil 209 only needs little electric current, so just can save the energy and magnetizing power.

When multiturn coil 209 is disconnected when keeping OFF213, magnetic particle 211 makes that owing to the effect of the remanent magnetism of location-plate 206 remains on suspended state magnetic fluid 211 is opaque.So, have the magnetic particle 211 of high specific weight also not accumulate in the bottom that magnetic fluid is filled chamber 203, and can be arranged in vertical row fast and not free delay when magnetic particle 211 when the OFF attitude converts the ON attitude to.

Being appreciated that location-plate 206 is not limited to the Cobal material, can be other ferrimagnet, Ni alloy for example, Ba ferromagnet, perhaps γ iron oxide.Though the diameter in the hole, garden 207 on the location-plate 206 and the diameter of the cavity 203 on the substrate 202 are 1: 1,, corresponding to the single cavity 203 on the substrate 202, the more aperture 217 of more number can be arranged, as shown in figure 35 on location-plate 206.Under the kind situation of back, the xsect of aperture 217 is hexagon preferably, thereby constitutes honeycomb.So just can reduce lighttight area and make the xsect of opening reach best.Obviously in embodiment 1 to embodiment 6, can equally successfully use the location-plate 206 that has shape hole, garden 207 or 217.

The display that the present invention proposes helps increasing screen size, and not only 50 inches but also can be 100 inches or 200 inches wide, the common liquid crystal display of this point be difficult to realize.Also may realize giant-screen wall-hanging TV receiver, perhaps be used for the indoor and outdoors medium of advertisement, for example billboard and various visual commodity show.

According to the present invention, the piece that a plurality of magnetic fluids are filled be assigned to they separately pixel and also can be activated respectively by the effect in corresponding magnetic field so that under strictness control accurately, clearly produce image.

According to the present invention, the magnetic fluid filled chamber of given number is combined to form a display unit; A desirable screen size just can constitute by the display unit of respective number is linked together.

According to the present invention, when a plurality of magnetic fields genetic horizon (each all has respectively in front two spiral electrode bars with the back side) is repeatedly put together mutually so that each series helix shape electrode strip when all constituting a multiturn coil, the thickness of substrate takes place in whole magnetic field, compared with using common coil, reduced greatly.So,, make the magnetic field generator of magnetic fluid orientation can use littler electric current and realization effectively along with reducing of magnetic fluid display thickness.

And, according to the present invention,, be connected with the electric current regulating element between each multiturn coil and the concentric line when one group of multiturn coil and concentric line electric connection mutually, only allow the electric current folk prescription to flow to concentric line from multiturn coil to ground.Thereby stoped do not wish the electric current from the concentric line to the multiturn coil that occurs to make the corresponding circuit arrangement extensive use be arranged.

According to the present invention, this Current Regulation element is a clear glass encapsulation diode; The latter can be installed on the transmitance region, thereby the dirigibility on the layout is provided.

According to the present invention, the multiturn coil with desirable output can stack each other and be bonded together and prepare by the magnetic field genetic horizon with respective number.

According to the present invention, the spiral electrode bar on all layers is being connected, when the formation multiturn coil is connected with concentric line, realize that also one prevents that inverse current from flowing to the device of multiturn coil from concentric line.
