Fig. 1～5 are continuous to show that preparation according to the embodiment of the present invention is used for the method for the filter 100 of shield electromagnetic interference.By using offset printing device 500 can prepare this filter that is used for shield electromagnetic interference 100.With reference to Fig. 1～5, will explain successively that below preparation is used for the method for the filter 100 of shield electromagnetic interference.
At first, Fig. 1 has schematically shown the process of discharging conductive paste 10a from distributor (dispenser) 51.The surface that circle has shown the gravure roll 55 of amplifying is amplified on Fig. 1 top, and the surface profile that circle shows gravure roll 55 is amplified in Fig. 1 bottom.
As shown in Figure 1, offset printing device 500 comprises distributor 51, scraper 53, gravure roll 55 and blanket roll 57.The adherography of use offset printing device 500 comprises removes step (off process) and fixing step (set process).In removing step, conductive paste 10a is shifted out from gravure roll 55.In fixing step, the conductive paste 10a that shifts out is coated on the glass substrate 20.Distributor 51 is discharged conductive paste 10a with the predetermined time interval.The conductive paste 10a that discharges from distributor 51 is contained in the groove 551 that forms in the gravure roll 55.
Described conductive paste 10a can comprise rubber-like organic material, conducting metal, flux, adhesive etc.Boiling point is not less than 200 ℃ material can be used as flux, and frit (glass frit) can be used as adhesive.Described organic material can comprise acrylate, acryl resin (acrylresin), polyester, polyurethane, oligomer etc.In the plasticizing process of glass substrate 20, remove described organic material.Described conductive paste 10a can further comprise black pigment.
Because conducting metal can absorb the electromagnetic interference by the filter 100 that is used for shield electromagnetic interference, so the effect excellence of shield electromagnetic interference.Silver, copper, nickel or its alloy can be used as conducting metal.Because above-mentioned conducting metal has good electrical conductivity, they are shield electromagnetic interference effectively.
It is represented to amplify circle as the top of Fig. 1, and groove 551 is formed on the surface of gravure roll 55.Groove 551 comprises first and second groove parts 5511 and 5513.Described first and second groove parts 5511 and 5513 intersect each other.Described first and second groove parts 5511 and 5513 intersect each other to form angle α 1.This angle α 1 can be at 60 degree to the scope of 120 degree.If described angle α 1 is too big or too little, the aperture opening ratio of shield member 10 (being shown among Fig. 6) can become too small, because the distance between first and second groove part 5511 and 5513 becomes too small.More preferably, described angle α 1 can be at 80 degree to the scope of 100 degree.In this case, can suitably keep distance between first and second groove parts 5511 and 5513.In addition, most preferably, described angle α 1 is 90 degree substantially.
In embodiments of the present invention, by using the netted shield member 10 (being shown among Fig. 6) of gravure roll 55 (being shown among Fig. 3) preparation that forms meshed grooves 551 therein.If the direction of the extension of the direction of rotation of gravure roll 55 and groove 551 intersects each other with the right angle, the conductive paste 10a that is contained in the groove 551 can not finely shift out from groove 551.
That is to say,, be not easy from gravure roll 55, to shift out conductive paste 10a because conductive paste 10a is subjected to the influence of the rotatory force of gravure roll 55 hardly.On the contrary, if the direction of rotation of gravure roll 55 is identical with the direction of the extension of groove 551, the rotatory force by gravure roll 55 can fully shift out conductive paste 10a.
As amplifying as shown in the circle on the top of Fig. 1, first groove part 5511 adjacent one another are intersects each other to form polygon 111 with second groove part 5513 adjacent one another are.This polygon 111 is square substantially.In this case, the shape optimization of shield member 10 (being shown among Fig. 6), thus make the maximum effect of shield electromagnetic interference.
Form the same length of the four edges of polygon 111.Because the same length of four edges, the shape of shield member 10 is regular.Therefore, owing to the light intensity that sends by the opening 105 (being shown in Fig. 6) corresponding to polygon 111 is even, can show uniform image.Simultaneously, in the amplification circle of Fig. 1, this polygon 111 is shown as square, but this only is diagram the present invention, and the present invention is not limited to this.Therefore, can form and have difform polygon 111, for example rectangle, rhombus etc.
As amplifying as shown in the circle, less and make the aperture opening ratio maximization can improve exploration on display resolution ratio by making the width W that forms first groove part 5511 on the top of Fig. 1.Based on this, the width of first groove part 5511 can be greater than 0 but is not more than 50 μ m.In this case, with the naked eye can not observe the shield member 10 (being shown in Fig. 6) that forms by first groove part 5511.If the width W of first groove part 5511 is too big, because aperture opening ratio reduces the exploration on display resolution ratio deterioration.More specifically, the width W of first groove part 5511 is preferably in the scope of 15 μ m～30 μ m.
Simultaneously, the mean pitch P of described first groove part 5511 can be greater than 0 but is not more than 500 μ m.If the mean pitch P of described first groove part 5511 is excessive, owing to do not form shield member 10 densely, electromagnetic interference may not can be absorbed but escapes into the outside.Therefore, the effect of shield electromagnetic interference will deterioration.More particularly, the mean pitch P of described shield member 10 is preferably in the scope of 200 μ m～400 μ m.
If groove only forms along the direction corresponding to the gravure roll direction of rotation, can not form the mesh shields member in embodiments of the present invention.That is to say that this netting gear has rectangular shape.Because groove also should form along the direction that intersects vertically with the gravure roll direction of rotation, described conductive paste is difficult to transfer on the blanket roll.
Amplify as shown in the circle as the bottom of Fig. 2, be formed in the gravure roll 55 along oblique extension and first and second groove parts 5511 and 5513 that intersect each other.Therefore, because groove part does not form along the direction perpendicular to the direction of rotation of gravure roll 55, described conductive paste 10a can transfer on the blanket roll 57 effectively.
Described first groove part 5513 along oblique extension becomes angle α 2 with the contact wire J-shaped, and described contact wire J intersects each other to form by gravure roll 55 and blanket roll 57.At this, described angle α 2 can be at 20 degree to the scope of 70 degree.If described angle α 2 is excessive or too small, groove part forms along the approaching direction of direction that will be parallel with contact wire J, thereby conductive paste 10a can not transfer on the blanket roll 57 effectively, and more particularly, described angle α 2 can be at 35 degree to the scopes of 55 degree.
Then, Fig. 2 has schematically shown the step of removing the conductive paste 10a that overflows from groove 551.
As shown in Figure 2, owing to the amount that is contained in the conductive paste 10a in the groove 551 is bigger, conductive paste 10a may overflow to the outside of groove 551.Therefore, when gravure roll 55 when the direction shown in the arrow (counterclockwise) is rotated, the conductive paste 10a that overflows is removed by scraper 53.Because scraper 53 contacts with the outer surface of gravure roll 55, overflow can be removed effectively to the conductive paste 10a of groove 551 outsides.Therefore, the groove 551 of gravure roll 55 can suitably be filled by conductive paste 10a and can not be overflowed conductive paste 10a.
Fig. 3 shows that schematically the conductive paste 10a that will be contained in the groove 551 transfers to the step of blanket roll 57.
As shown in Figure 3, blanket roll 57 is oppositely arranged with gravure roll 55.Blanket roll 57 is with direction (clockwise direction) rotation opposite with the direction of rotation of gravure roll 55.Therefore, when gravure roll 55 contacted with blanket roll 57, the conductive paste 10a that is contained in the groove 551 was transferred on the blanket roll 57.Therefore, conductive paste 10a adheres on the outer surface of blanket roll 57.
Fig. 4 has shown that schematically blanket roll 57 is coated in step on the glass substrate 20 with conductive paste.
As shown in Figure 4, when along the direction of arrow indication on glass substrate 20 when mobile, blanket roll 57 is coated in conductive paste 10a on the glass substrate.Therefore, netted conductive paste 10a is formed on the glass substrate 20 to form shield member 10 (being shown in Fig. 1).
Fig. 5 schematically shows the step that the glass substrate 20 that will be coated with conductive paste 10a plastifies.Also can before plastifying step, make conductive paste 10a drying.
As shown in Figure 5, pack glass substrate 20 into heating furnace 90 heating under the temperature in 500 ℃～540 ℃ scopes, thereby removed the organic material that is included among the conductive paste 10a as shown by arrows.If the heating-up temperature of glass substrate 20 is lower than 500 ℃, can not fully remove the organic material that is included among the conductive paste 10a, thereby the conductivity of the shield member of feasible preparation is too poor.Therefore, described shield member can not be realized electromagnetic interference shield function.On the contrary, if the heating-up temperature of glass substrate 20 surpasses 540 ℃, the mainly resistance to impact reduction of the glass substrate 20 that forms by reinforcing glass.In embodiments of the present invention, glass substrate 20 is plastified under relatively low temperature.Because described shield member is to be made of individual layer, described glass substrate 20 can plastify under relatively low temperature, and the reduction of the intensity by preventing glass substrate 20 can keep the resistance to impact of glass substrate 20.
As mentioned above, glass substrate 20 to be removing organic material, and can directly form shield member.That is to say, directly formed the filter that is used for shield electromagnetic interference of individual layer and do not need to carry out other step, for example the etching of conductive paste 10a.Therefore, because step is simple, can reduce the preparation cost of the filter that is used for shield electromagnetic interference.
Because preparation according to the embodiment of the present invention is used for the adherography of the filter of shield electromagnetic interference and comprises the plasticizing step, the resin substrate of poor heat resistance can not be used for adherography.Therefore, glass substrate 20 is as replacing resin substrate.Owing to it will be appreciated by those skilled in the art that other content of described adherography, it no longer given unnecessary details at this.
When using photoetching process to replace the adherography preparation to be used for the filter of shield electromagnetic interference, at first copper film is adhered on the resin molding.Then, be layered in the etchant resist of drying on the copper film and carry out step of exposure, development step, etch step and strip step to form figure.Therefore, the preparation process complexity, and productive rate is not good.
In addition, when being used for the filter of shield electromagnetic interference, must obtain required conductivity by formation figure and copper facing thereon on resin molding by use galvanoplastic (plating method) preparation.Yet the waste liquid that electroplating process produces causes environmental pollution.
Use in above-mentioned photoetching process or the galvanoplastic and can not directly on glass substrate, form figure.For example, the motherboard (mother substrate) with the form of coiled roller is immersed in the electroplating bath of galvanoplastic.Yet, because the form that glass substrate can not the coiled roller, thereby can not form shield member by electroplating glass substrate.In addition, when using glass substrate, owing to figure should be adhered on the glass substrate, so the process complexity.Adherography can address the above problem.That is to say that in adherography, because the shield member 10 of individual layer is formed directly on the glass substrate 20, process is simplified, thereby has reduced preparation cost.On the contrary, because the shield member that formation is formed by multilayer in plated by electroless plating method (nonelectrolytic plating) waits, so preparation cost is very high.In addition, in adherography, do not discharge harmful substance, so can not produce pollution.
