Description

Make the method for elastic EL lamp

The application is that simultaneously pending trial, the application number of submitting on December 30th, 1996 of assigning simultaneously are dividing an application of 08/774743 U.S. Patent application " ELASTOMERIC ELECTROLUMINESCENT LAMP ", and this U.S. Patent number is 5856030.

Quote as proof in this application assign simultaneously and simultaneously the application number of submitting on May 30th, 1996 of pending trial be 08/656435 U.S. Patent application " ELECTROLUMINESCENT SYSTEM IN MONOLITHICSTRUCTURE ".

The application relates generally to electroluminescent lamp, be particularly related to independence (self-contained) the electroluminescence system that is disposed in the elastic construction, this electroluminescence system effectively and at low cost is pasted on the various substrates of variable 3D shape with transfer printing (trnasfer) form, perhaps is assemblied in the other products as membranaceous element independently.

Relate to by the inventive embodiment of above-mentioned U.S. Patent application " ELECTROLUMINESCENT SYSTEM IN MONOLITHICSTRUCTURE " (" formerly invention ") instruction and to have electroluminescence (EL) system that its layer forms the unit carrier of one-piece construction.Preferred unit carrier is a vinylite in this system.An advantage of the electroluminescence system of this one chip form is, layer therein can resemble in silk-screen printing technique the printing ink by copying on various substrates.

Known elastic construction in the prior art has unique and useful characteristic.Its effect is very as firm film, and the ductility of elastic construction and flexibility can be used for using in the application of the stronger or element that plasticity is stronger of rigidity.

Use elasticity electroluminescence (" EL ") lamp that many potential advantages are arranged.For example, in mobile phone or other personal communicator, can realize high submissive and resilient backlight keyboard plate.

In addition, elastic EL lamp can constitute by the transfer printing form, is pasted on then on the fibrous substrate such as fabric (fabric).Experiment shows, according to invention formerly, usually requires to prepare substrate in advance by best result to the substrate silk screen printing EL system such as fabric the time.At first, this fabric does not always have the chemical compatibility with the best of EL system ground floor.Secondly, found that fabric fibre has the trend of " uprightly " and conflicts with EL system smooth and uniform copying.As a result, although invention formerly has been found that all functions of this fabric, electroluminescent with low quality.Therefore find that on substrates such as fabric " podium level " of printing element carrier (not having the EL active component) is favourable to suppress these factors in advance.Thereby according to formerly inventing the copying of EL system on podium level.

Although dispose the performance that this podium level can strengthen the EL lamp, should be appreciated that, the manufacturing step that this need add, time, material and manufacturing process cost increase thereupon.

And, also show according to the further experiment of copying EL system of invention formerly, make the zone of the bearing printing printing operation that flattens when becoming the plane best.For example, for the printing of fabric, use the clothes such as T-shirt can easily realize this " flattening ", but use other clothes such as jacket or baseball cap so easily not realize, for them, the final profile of clothes can be damaged or belittle to " flattening " step.

Therefore in the prior art elastic EL lamp there is general demand.Such elasticity lamp is preferably as the parts in the product that requires flexible back lighting.Perhaps, with the transfer printing form, this elasticity lamp can improve the EL system of invention formerly in the application that comprises on the fibrous substrate of fabric, and does not cause additional cost and prepare substrate in advance to accept the manufacturing step of EL system.Elastic EL lamp also helps the EL system of formerly inventing less damage ground to be used for the substrate of 3D shape.

The EL lamp that the present invention relates to substantially according to invention formerly but make as discrete elastic construction.If desired, this structure can be fixed on the substrate subsequently so that utilize the benefit of " transfer printing ".Perhaps, elastic construction also can be used as discrete independent electroluminescent cell in the application such as finger-board, wherein the EL lamp of film like preferably.

According to the present invention, integrally make elastic EL lamp with silk screen printing or other printing technology.Therefore, with respect to according to formerly inventing the EL lamp directly being printed in situation on the substrate, common silk screen printing cost of the present invention and logistic work are more not complicated or thorny., lamp is constituted elastic structure and can obtain various advantages.If elastic structure is pasted on the substrate with the transfer printing form, can prepare to have fabric or other substrate of podium level so.And, have significant ductility and flexibility according to the present invention with the elastic EL lamp of transfer printing form, can be pasted on subsequently actual for any 3D shape and need not " it is smooth to flatten " implement on the substrate in zone of typography.On the other hand, if elastic construction is used as independent component, it can be produced in batches and easily be assemblied in the product resembling pad or other film like element thereafter potentially so.

In sum, according to the EL lamp of elastic construction of the present invention, at first first outer shell is printed in the heavyweight of purchasing in market and shifts on the peeling paper (heavy-grade transfer release paper).But first outer shell of copying subsequently is with the one chip first outer shell thickness of realizing being scheduled to.And, can and/or print one or more layers according to figure dyeing, thereby can make the ground floor of shell that predetermined outward appearance (for example indicating icon or keyboard flaggy) is arranged under natural daylight.

The material of shell ground floor best (although and not requiring) is limpid or half limpid polyurethane.Experiment shows that this material has excellent elastic performance.And, confirmed that this material and similar all materials and the most of substrate itself that may run into all have chemical stability in the EL lamp is used, these materials comprise the layer that shifts peeling paper, EL system and forme can be pasted on adhesive on the substrate that these substrates comprise fibrous substrate.Polyurethane also is the material that fabulous flexibility and ductility are arranged, can adaptation easy to manufacture or " packing " and all can not have the elastic EL lamp that wound ground receives on the substrate of similar any 3D shape.

Shift on the peeling paper in case the ground floor of shell is printed on, best (although and not requiring) just according to invention formerly, is imprinted on the EL system on first outer shell.The EL system is less on first outer shell, reserves the first shell border around externally.Then with the second outer shell copying on the top of EL system, around the edge and the first shell boundary combinations, thus with the EL system sealing in the enclosure.In shell, prepare or keep suitable window, can electrically contact the EL system that introduces.Have, second outer shell is preferably by the polyurethane of several middle layers printing with the realization predetermined thickness again.In the predetermined thickness of realizing polyurethane, this design is preferably guaranteed EL lamp and external electric isolation in the enclosure, and shell is a waterproof.

When the expectation elastic EL lamp when the transfer member (transfer), best is on second outer shell with the form copying or the last thermal adhesive layer of heat seal of film.Thermal adhesive layer is polyurethane preferably, although this is not special requirement.By heating and pressurization, this thermal adhesive layer is pasted on transfer member on the substrate., it should be noted that also available other method known in the art will be pasted on the substrate as the EL lamp of elastic construction, for example contact bondingly etc., under the bonding situation of contact, do not need thermal adhesive layer.And,, do not need heat adhesive probably when elastic EL lamp during as the independent component in another product yet.

Obviously, technical advantage of the present invention is, can prepare the EL lamp of elastic construction discretely by transfer form and with the substrate surface that will be applied thereto (for example fiber), and this has eliminated the requirement of preparation substrate surface before the EL system applies.However equal substantially the EL system itself is applied directly to situation on the substrate as the silk screen printing step of the EL lamp of elastic construction and needed cost by the transfer form manufacturing.Therefore, the resource expense with equivalence can be used for fibrous substrate with more general and more reliable EL lamp, for example has on the fiber of various 3D shapes.

Further technical advantage of the present invention also is, as the EL lamp of elastic construction fabulous ductility and flexibility arranged.Therefore,, can easily be provided with, be fixed in fast and easily on the substrate with various 3D shapes, for example on the front of baseball cap with transfer form.In addition,, can produce in batches and can be easily and for example be installed in mobile phone etc. apace and need in the product of keyboard, wherein be configured as membranaceous finger-board and more have superiority with the form of independent component

Further technical advantage of the present invention also is, shell can comprise the dye layer that for example indicates icon or other figure according to chromatic graph shape, thus as elastic construction the outward appearance of EL lamp under the natural daylight when being excited under soft light the outward appearance of EL lamp visually be consistent.

Further technical advantage of the present invention also is, by producing a large amount of elastic EL lamps in batches to individual a series of copyings of shifting peeling paper.Can make these in the aligned in position that shifts a large amount of EL lamps on the peeling paper, dash by single hammer and wear and to sweep away the EL lamp from peeling paper in large quantities.The resource during but this optimum utilization EL lamp is made provides than the more effective saving of conventional method that respectively the EL lamp is offered substrate.

More than summarize and broadly clear feature of the present invention and technological merit, to understand detailed description of the present invention better.The supplementary features of the present invention and the advantage that constitute claim theme of the present invention will be described below.Should be realized that those skilled in the art can easily utilize disclosed design and specific embodiment, revise or design other structure based on this and implement to realize identical purpose of the present invention.Those skilled in the art it should further be appreciated that this equivalent structure does not break away from the spirit and scope of the present invention that proposed by claims.

In order more completely to understand the present invention and its advantage, carry out following explanation with reference to the accompanying drawings, wherein:

Fig. 1 is the profile of the preferred embodiment of elastic EL lamp of the present invention;

Fig. 2 is the perspective view of profile shown in Figure 1;

Fig. 3 is from shifting the perspective view of the elastic EL lamp of the present invention that peeling paper peels off;

Fig. 4 represents power supply is supplied with the method for optimizing of elastic EL lamp of the present invention;

Fig. 5 represents power supply is supplied with another method for optimizing of elastic EL lamp of the present invention; With

Fig. 6 represents to have the zone that part cuts the elastic EL lamp 300 of part 601, has disclosed the various dye technologies of layer, to produce not luminous/luminous outward appearance of selecting.

Fig. 1 represents the profile as the most preferred embodiment of the EL lamp of elastic construction according to the present invention.By reference above-mentioned U.S. Patent application " ELECTROLUMINESCENT SYSTEM IN MONOLITHICSTRUCTURE ", be shown among Fig. 1 excitation EL system substantially as described in the application disclosed like that, use at first the common unit carrier such as vinylite with the gel form coating.However, should be understood that the present invention does not have special requirement to concrete EL used herein system, and scope of the present invention expectation comprise can be as the many different EL system of elastic structure.

According to Fig. 1, all layers copying shifted on the peeling paper 102.In most preferred embodiment, shifting peeling paper 102 is paper of making such as with Midland Paper-Aquatron Release Paper.Will be further appreciated that another example as this paper, also available according to transfer stripping film of the present invention.

The most handy silk-screen printing technique coating well known in the prior art all shown in Fig. 1 (with figure subsequently) layers subsequently., should also be understood that the present invention is not limited to be equipped with the elastic EL lamp that only applies its layer with silk screen print method, also other method of available overlay constitutes elastic EL lamp of the present invention.

With 104 copyings of first outer shell in shifting on the peeling paper 102.Best form copying first outer shell 104 with several middle layers is with total combination thickness of realizing being scheduled to.Also help to dye or the dyeing of other special layers by form copying first outer shell 104 in many intermediate layers, to realize the predetermined natural daylight outward appearance of EL lamp.First outer shell 104 best (although and not requiring) is a polyurethane, for example the Nazdar DA 170 that mixes with catalyst DA 176 in 3: 1 ratios.This is commercial purchase and will be used for the polyurethane printing ink of silk screen printing.As mentioned above, this polyurethane present the desired elastic characteristic of outer shell, with the chemical stability of the other parts of EL lamp and fabulous ductility and flexibility.This polyurethane also is set with by the multilayer copying, reaches the final thickness of monolithic when cured.At last, this polyurethane is colourless and normally limpid basically, therefore its layer also will be set so well, with accept dyeing or other painted processing (as following further specified), provide its outward appearance to be designed to natural daylight to compensate the EL lamp of its exciting light outward appearance by soft light.

Turn back to Fig. 1, obviously, 104 copyings of first outer shell are being shifted on the peeling paper 102, and be provided as 105 spaces, border at the edge of EL system layer 106-112.Can provide bonding second outer shell 114 to seal the zone of EL system fully so thereon, will describe this scheme in more detail below.

Preferably disclosed like that according to above-mentioned U.S. Patent application " ELECTROLUMINESCENT SYSTEM IN MONOLITHICSTRUCTURE ", follow the copying of EL system on first outer shell 104.As seen, according to Fig. 1, the EL lamp constitutes with " facing down ", so tin indium oxide (" ITO ") layer 106 at first is formed on first outer shell 104.

Then, with front busbar 107 (preferably silver) copying on ITO layer 106.Then with electroluminescence layer 108 (preferably fluorophor/barium titanate mixture) copying on the ITO layer 106 and front busbar 107 on.Although the present invention does not have special requirement, experiment shows, when front busbar 107 be arranged on the surface of ITO layer 106 rather than during opposite situation (ITO layer 106 is printed on the front busbar 107) performance improve.This is because when ITO layer 106 is stacked and placed on front busbar 107 surperficial going up, finds that the vinylite carrier in ITO layer 106 has the trend of curing, thereby form the barrier layer of the conductivity of the front busbar 107 that suppresses formerly stacked., otherwise then do not produce this phenomenon, and such front busbar 107 is printed in preferably on the ITO layer 106.

Refer again to Fig. 1, dielectric layer 110 (preferably barium titanate) copying is on electroluminescence layer 108, and backplate layer 112 (preferably silver or carbon) copying is on dielectric layer 110 then.Note, according to disclosing of above-mentioned U.S. Patent application " ELECTROLUMINESCENT SYSTEM IN MONOLITHIC STRUCTURE ", ITO layer 106, front busbar 107, electroluminescence layer 108, dielectric layer 110 and backplate layer 112 are so constituted an EL system example that possesses electroluminescence characters of the present invention.

Again referring to Fig. 1, copying second outer shell 114 on the electrode layer 12 overleaf then.From Fig. 1 as seen, the best copying of EL system layer 106-112 must be reserved 105 spaces, border.This allows copying second outer shell 114, it is adhered on first outer shell 104 around 105 on the border, thereby EL system electricity is isolated in (1) sealing EL system and (2) make whole EL lamp assembly moistureproof basically.Preferably also use with first outer shell, 104 identical materials to prepare second outer shell 114, so that when finishing, two parts capable of being combined form the one chip shells around the EL system.As mentioned above, the polyurethane of Shi Heing for example is the Nazdar DA 170 that mixes with catalyst DA 176 in 3: 1 ratios.And also as mentioned above, second outer shell 114 can also be with the form copying in a series of intermediate layers, to reach preset thickness.

Last (top) layer that is shown among Fig. 1 is an optical adhesive layer 116.As described, elastic EL lamp of the present invention application is to be pasted on the substrate as transfer member.In this case, can use heat adhesive to paste transfer member, for example contact other bonding and so on method of attaching although can use.The advantage of heat adhesive is, can use the method for manufacturing technology printing identical with other layer of assembly, can store or store transfer member then, prepares to use simple hot-pressing technique that it is pasted on the substrate subsequently.In this case, as shown in Figure 1, adhesive phase 116 is printed on second outer shell 114.

Certainly, be during of the present invention other of the independent component of another product used, not need optical adhesive layer 116 probably at the EL lamp.

The further feature that is shown among Fig. 1 is back side contact window 118A.Obviously, for electrical power being introduced, require back side contact window 118A to arrive backplate layer 112 by the adhesive phase 116 and second outer shell 114 with excitation EL system layer 106-112.Similarly, require another window to arrive front busbar 107 by adhesive phase 116, second outer shell 114, backplate layer 112, dielectric layer 110 and electroluminescence layer 108.Described another window is not shown among Fig. 1, for clarity sake omits, but can see this part 118B on Fig. 2 of perspective section view of the present invention.

Turn back to Fig. 2, Fig. 2 is the section perspective view partly that exploded view 1 is described.First outer shell 104 at first copying in shifting on the peeling paper 102.Border 105 also is tangible.106 copying of ITO layer are on first outer shell 104, and busbar 107 copyings in front are on ITO layer 106.Then with electroluminescence layer 108 copyings on ITO layer 106 and cover front busbar 107, so, with dielectric layer 110 copyings on electroluminescence layer 108.112 copying of backplate layer on dielectric layer 110, are sealed whole assembly around border 105 usefulness copyings then on backplate layer 112 and with second outer shell 114 of first outer shell 104 combination.Then with adhesive phase 116 copyings on second outer shell 114.

As mentioned above, Fig. 2 has also showed anterior contact window 118B, and obviously this window passes all layers arrival front busbar 107 and easily electrical power is supplied in this thus.According to Fig. 2 obviously as seen, second outer shell 114 is set, is sealed in the edge of each insert layer on front busbar 107 in the anterior contact window 118B.

It is also ready after Fig. 3 is illustrated in and finishes like that as mentioned above substantially from shifting the whole assembly that peeling paper 102 shifts.After on being pasted on substrate, peel off elastic EL lamp 300 (comprising each layer and part 104-116 as illustrated in fig. 1 and 2) from shifting peeling paper 102 back sides.Also can see pass away contact window 118A and anterior contact window 118B.

Also will be appreciated that (although not shown), when the lamp of a large amount of same design of demand, the present invention also can provide than the more economical manufacturing of traditional E L lamp method of manufacturing technology.Screen printing technique allows a large amount of EL lamps 300 can be formed in big opening on the transfer peeling paper 102 simultaneously.Can with these lamp 300 location registration on individual peeling paper 102, bore a hole simultaneously with suitable big punch then.

As mentioned above, according to the present invention, but also design and use dyeing or the preparation on the intermediate layer of first outer shell of selecting 104 of other technology present the frontal appearance of the elastic EL lamp 300 of natural daylight.According to this technology, Fig. 3 has also described the first of the sign icon 301 that appears when elastic EL lamp 300 is peeled off at the back side.

, at first, two selective preferred embodiment electrical power being supplied with elastic EL lamp of the present invention to be discussed also thereupon.With reference to Fig. 4, can behind the upper right side, turn over observation elastic EL lamp 300, to represent back of the body contact window 118A and anterior contact window 118B.Introduce electrical power from far end supply by soft bus 401, for example, as known in the field, bus 401 can be the printed circuit that is printed in the silver on the polyester.Perhaps, Rou Ruan bus 401 can comprise the conductor (for example silver) that is printed on the thin bar of polyurethane.Soft bus 401 terminates in connector 402, and the size of predetermined connector 402, shape and configuration are to closely cooperate with back of the body contact window 118A and anterior contact window 118B.Connector 402 comprises two contacts 403, and each is loaded into respectively among back of the body contact window 118A and the anterior contact window 118B, and by mechanical pressure, contact 403 is with the EL system in the required power supply elasticity of supply EL lamp 300.

In most preferred embodiment, contact 403 comprises the conductive silicon rubber contact pad, and this pad is connected to electrically contacting on the contact in back of the body contact window 118A and the anterior contact window 118B with the terminal of soft bus 401.This set advantageous particularly when being pasted on elastic EL lamp 300 on the substrate with heat adhesive.Be used for the hot pressing that transfer member is pasted on the substrate is produced mechanical pressure, with enhancing silicon rubber contact pad and in the electrically contacting between the contact surface that electrically contact on the contact 403 and in contact window 118A and 118B.The coating silicon adhesive also can further strengthen and electrically contacts between contact surface.Can make (enabling) silicon rubber contact pad of energizing with Chromerics, the producer is called " conductive silicon rubber ".The silicon adhesive of energizing is Chromerics 1030.

Use the concrete advantage of silicon rubber contact pad to be, they have the trend of the relative shear displacement that absorbs elastic EL lamp 300 and connector 402.For example, compare with the epoxide-resin glue mechanical splice point.Adhesion itself between transfer member 300 and connector 402 is very strong, but rigidity is so arranged and be difficult for bending, so that on these two parts or one of them can not be directly transferred in the relative shear displacement between transfer member 300 and the connector 402.Finally, always there is an interface to be cut off probably in epoxide-resin glue interface (epoxy resin/transfer member 300 or epoxy resin/connector 402).

, on the contrary, the elasticity of silicon rubber contact pad makes the silicon rubber interface that provides absorb such relative shear displacement thus and does not make pad or electromechanical joint become bad.Make because of electrical pickoff and suffer catastrophic shear stress premature loss power.

Another preferred embodiment that electrical power is supplied with elastic EL lamp of the present invention is shown among Fig. 5.In this case, when printing front busbar 107 and backplate layer 112 (such just described with reference to Figure 1), the border that also surpasses elastic EL lamp 300 is thereon extended printing and is reached on the hangover printed busbar 501.The suitable substrate of printed busbar 501 of being used to trail can be for example from " hangover " of first outer shell 104 or second outer shell, 114 extended polyurethane.Obviously, if desired, in the also salable hangover at first outer shell 104 or second outer shell 114 of the conductor of printed busbar 501 is extended.Utilize hangover printed busbar 501 to connect electrical power then from transfer member 300 far-ends.

Be noted that power supply in a preferred embodiment uses the battery/inverter printed circuit with very little profile.For example, the inverter based on silicon disposes very little profile and size.These power units can easily, safely and be hidden abruptly and use thereon in the product of elastic EL lamp of the present invention.For example, in clothes, these power supply units can be hidden in the special pocket effectively.For safety salable this pocket (for example false lining).Power supply in this area the 6V lithium battery of standard also will provide ductility and flexibility to make battery folding and crooked with clothes.Also can find out, can easily seal as shown in Figure 4 soft bus 401 or all as shown in Figure 5 hangover printed busbar 501, be hidden in the product structure easily then to provide completely electricity to isolate.

Turn back to printing technology, the invention also discloses the improvement aspect EL lamp printing technology, developed EL lamp (comprising elastic EL lamp), its passive natural daylight appearance design becomes and the complementation of active electroluminescence outward appearance.This complementation comprises that the passive natural daylight outward appearance that designs this EL lamp seems substantially identical with active electroluminescence outward appearance, thereby at least aspect image and tone, whether the EL lamp is luminous or not luminous seems it all is identical.In addition, also can design lamp, show constant image, but when with not luminous when luminous on the contrary mutually, its part can change tone.In addition, can design the outward appearance of EL lamp, so that it changes outward appearance when luminous.

Can be in conjunction with comprising that with the printing technology that produces these effects (1) changes the kind (in the glow color) of the fluorophor that is used for electroluminescence layer 108, (2) selective staining, make the layer of copying on electroluminescence layer 108 painted with it, (3) use the spot size printing technology, realize the change gradually of the obvious tone of luminous and not luminous EL lamp.

Fig. 6 shows these technology.The part of elastic EL lamp 300 is cut away part 601 and is showed electroluminescence layer 108.Cutting away in the part 601 in part, the electroluminescence of three separation of copying zone 602B, 602W and 602G, the electroluminescent material of the fluorophor that comprises emission different colours light (being respectively blue, white and green) is used in zone of each printing.Be noted that screen printing technique known in the art can copying three separate areas 602B, 602W and 602G.By this way, but the various zones of different colours light are launched in copying, if desired, can make up with the zone of not luminous (promptly not having the copying electroluminescent material), can show any design, sign icon or the information that will show when excitation electroluminescence layer 108.

Select painted (preferably by dyeing) other layer between electroluminescence layer 108 and EL lamp front portion, thereby when being subjected to encouraging, also can change the outward appearance of electroluminescence layer 108.Also this selection of may command is painted by layer that copying in the institute's favored area on electroluminescence layer 108 only is painted.

Refer again to Fig. 6, elastic EL lamp 300 has first outer shell 104 that is positioned on the electroluminescence layer 108, and as illustrated in fig. 1 and 2, second outer shell 104 can print by stacked multilayer intermediate layer and meet the requirements of thickness.One or more in these layers comprise the outer shell material that is colored to predetermined color and copying, thus the described painted exciting light outward appearance that can replenish expectation thus.This is that the EL lamp replaces desired entire combination result when luminous and not luminous.

For example.In Fig. 6, suppose regional 603B dyeing for blue, regional 603X is unstained, and 603R dyeing is purple for red and regional 603P dyeing.The natural daylight outward appearance of elastic EL lamp 300 should be redness and the purple bar paten 605 with blue border 606 substantially.Red area 603R and violet region 603P will change the white color of regional 602W below, the cream-coloured tone of regional 602B below the regional 603X that is unstained will keep is constant, blue region 603B will change light green/cream-coloured tone of following regional 602G, become the outward appearance of some dark blueness.Should be realized that, go back the blue color of selectable region 603B, during with the green combination of box lunch and following regional 602G, the natural daylight outward appearance is identical blueness substantially.

, when excitation elastic EL lamp 300, regional 603R, 603P and 603X will keep redness, purple and blueness respectively, launch the light time when the blue color with regional 603B changes from following bottle green fluorophor, and white portion 603B will become dark green.Like this, produce the effect as example, although promptly because of excitation, the part of image has changed outward appearance, and no matter elastic EL lamp 300 is luminous or not luminous, and another part of image is designed to seem identical.

Obviously, by the various painted phosphor areas of copying and in conjunction with above various pigmented section, make the luminous of lamp and not the possible design that interrelates of shiny appearance be hard-core.Should be appreciated that, in traditional E L manufacturing technology, can not utilize this luminous/not shiny appearance design flexibility and scope, in this technology, be difficult to accurately print various painted " zone " or as the intermediate layer in one chip thickness.It is also to be understood that, by the present invention and invention formerly (above-mentioned U.S. Patent application " ELECTROLUMINESCENT SYSTEMIN MONOLITHIC STRUCTURE "), with the whole EL of screen printing technique copying system, lamp and forme, can realize this luminous/not shiny appearance design flexibility and scope.

It is again emphasized that in above-mentioned tone technology, the fluorescent color dyestuff is preferably sneaked in the material that will mix colours, for example the situation with colouring or other dyed layer is opposite.Such dyeing helps at the reflection natural daylight and activates in the EL light from visually realizing the tone of equivalence.Sneak into by " repetition test " or with color of for example sneaking into the more traditional COMPUTER CALCULATION of colouring relatively well-known in the art, can realize that color sneaks into.

Still with reference to Fig. 6, Fig. 6 also shows the transitional region 620 between regional 603B and the 603X.Transitional region 620 expression is the navy blue tone of regional 603B (when the elastic EL lamp 300 is energized) zone of changing the light blue tone of regional 603X gradually into wherein.This is the new and unexpected effect that causes by the screen printing technique of making the present invention and the EL system utilization of invention formerly.

" some printing " is standardized in the printing industry.And, think and implement easily " to put and to print " technology with silk screen printing.The border " merging " that known " some printing " can make the adjacent area of two printings forms the zone of obvious transition together.By each point is extended to the transitional region from each adjacent area, and when stretching in the transitional region, these points reduce spot size and the interval that increases between the point just can form transitional region.Thereby in overlapping or when stack, enter its effect of adjacent areas from an adjacent area by transitional region and change gradually when the dot pattern in the transition zone.

Should be appreciated that, can easily realize this effect according to the present invention.Refer again to Fig. 6, copying provides the dye layer of special colour in regional 603B, and it has the point in transitional region of extending into 620, and wherein described point reduces size and increases interval between the point when described point stretches in the transitional region 620.The dye layer of special colour is provided in regional 603X with corresponding mode copying then, and it has the point in transitional region of extending into 620.The effect that obtains in natural daylight and excitation luminescence is that transitional region 620 presents the gradual change from a kind of tone to another kind of tone.
