Description
Technical field
The present invention relates to use ink jet printing method to manufacture the apparatus and method of color filter substrate (color filter substrate).
Background technology
Conventionally, such as the electronic equipment such as liquid crystal display device and semiconductor devices by form pattern manufacture on multiple layer.Photoetching process is widely used in forming pattern up to now.
The following principle of photoetching process utilization: specific photoresist (photo resist) (hereinafter referred to as " PR ") is receiving light time chemically reactive to change its proper characteristics (prosperity).At the negativity for color filter (negative) photoresist, only have the part that is not exposed to light be just melted and remove, occur crosslinked because be exposed to the part of light.At positivity (positive) photoresist of the metal electrode pattern for semiconductor devices and TFT, be decomposed to produce acid owing to being exposed to the part of light, there is the significant difference of expose portion and the unexposed portion solubleness to developer, made only to melt and remove expose portion.Thereby, in photoetching process, can use optionally radiant light of mask for desired pattern, there is the pattern with the pattern of this mask with same shape or anti-shadow shape to form.Photoetching process comprises: PR coating procedure, for PR is located to substrate; Exposure process, for using optionally radiant light of mask; And developing process, for using developer to remove to be exposed to the PR of part of light or the PR of part that is not exposed to light to form desired pattern.But, in photoetching process, should manufacture predetermined mask.And, the in the situation that of positive photoresist, should repeat chemical etching and stripping process as the subsequent process that is used to form metal electrode pattern.Thereby there is limitation: manufacturing process may be complicated, and may produce a large amount of poisonous chemical wastes.Therefore, thus manufacturing cost may increase weaken product competitiveness.
In order to solve photolithographic limitation, the roller printing method (roll printing process) of a kind of use print roller (printing roll) is proposed as the new method that is used to form pattern.In addition, actively carrying out with for using ink-jet printing technology to manufacture the relevant research of the technology of color filter substrate.
Have various roller printing methods, but roller printing method can roughly be divided into two class methods, i.e. gravure process (gravure printing method) and anti-shadow lithographic process (reverse offset printing method).
According to gravure process, China ink is coated on the reeded printed panel of tool to the unnecessary China ink of then raking off.Afterwards, use transferring roller that the China ink of staying in groove is transferred on substrate to carry out printing process.Because China ink is to use transferring roller to transfer on substrate, so used the area transferring roller corresponding with the area of desired display equipment.And, have in large-area situation at display device, can carry out transfer process and once form pattern.The printing process that gravure process is known as one and is suitable for being applied to every field---such as publication, packaging, viscose paper (cellophane), vinyl (vinyl), tygon (polyethylene) etc.---.And, studying gravure process is being used to form to having redness, green or blue multicolour pattern and being formed for preventing the metal pattern of the EMI screen layer that occurs static in PDP display of color filter.
For example, but in the typical gravure process that is used to form fine pattern, in large-scale substrate,---glass substrate---above carries out etching process to form groove, thereby manufactures printed panel.Because be filled into China ink in groove, only some is transferred roller and transfers on substrate, so may need extraly a compressing process to guarantee to be formed into by transfer the homogeneity of the thickness of the pattern on substrate.As a result, gravure process can be useful on and forms extensive pattern and have the pattern of shape of stripes, but is not suitable for forming fine pattern---the black matix (black matrix) of for example color filter or the pattern of TFT substrate.Accordingly, anti-shadow lithographic process can be mainly used in forming accurate fine pattern.
According to anti-shadow lithographic process, different from gravure process, China ink is coated in to blanket (blanket) upper, then the jut of the reeded printed panel of tool (protrusion) contact is coated to the China ink on blanket.Afterwards, less desirable pattern part is removed, the pattern part of staying on blanket is transferred on substrate to form desired pattern.And except the multicolour pattern of color filter, anti-shadow lithographic process can also form the fine pattern with various shapes---for example BM and TFT.In addition, manufacturing cost can reduce, and throughput rate can improve.But the blanket need to high-quality obtains fine pattern.And, be difficult to keep having the pattern of constant shape.
The in the situation that of ink jet printing method, compared with roller printing method, due to black diffusion, can reduce material consumption.In addition, needn't manufacture printed panel.Thereby ink jet printing method can be very effective to manufacturing color filter substrate.But, in ink jet printing method, spacer (barrier) must be set on object to be printed, stably to keep the shape of pattern when the ink-jet.
Thereby the color filter that continues to need research to manufacture more simply and have superior quality has again the method for the advantage of ink jet printing method simultaneously.

The invention provides the apparatus and method that use ink jet printing method to manufacture color filter substrate.According to the apparatus and method of described manufacture color filter substrate, use and comprised thering is roughness the blanket of printed layers of---it has pattern form---stably forms pattern, even if discrete spacer is not provided on substrate.
Hereinafter, in connection with brief description of the drawings exemplary of the present invention.
The device that uses ink jet printing method to manufacture color filter substrate comprises blanket 1, print roller 2 and exhaust unit 3.Blanket 1 comprises printed layers 11, carrier layer 12 and cushion 13.
Fig. 1 is according to the schematic cross sectional view of the blanket of one embodiment of the invention.Describe printed layers 11 in detail with reference to Fig. 1.
The China ink 31 discharging from exhaust unit 3 can directly be attached to printed layers 11, and then printed layers 11 contacts substrate 4 so that China ink 31 is attached on this substrate.
Can be the printed layers 11 with multiple coarse article (roughs) according to the printed layers 11 of one embodiment of the invention, this be different from the typical printed layers without roughness.Described roughness can have groove and projection.Hereinafter, the projection of roughness will be called as jut 112, and the recess of roughness will be called as groove part 111.Printed layers 11 is necessary parts of the present invention.Printed layers 11 can comprise that multiple groove parts 111 are to realize below by the following target of explanation.
According in the printed layers 11 of one embodiment of the invention, China ink is only filled in groove part 111, and is not filled in jut 112.Thereby China ink is not adhered to jut 112.Accordingly, even if discrete spacer is not provided on substrate 4, also the China ink being filled in groove part 111 stably can be transferred on substrate 4.
The present invention is not subject to the restriction of the size and dimension of groove part 111.Can set according to the size and dimension that is transferred into the pattern 5 on substrate 4 size and dimension of groove part 111.
And the present invention is subject to the restriction of the kind of described pattern.For example, described pattern can be to be selected from a pattern of following group: black matix (BM) pattern; Red (R), green (G), blue (B) honeycomb pattern; And column spacer patterns.
As mentioned above, the device of the manufacture color filter substrate providing is a kind of color filter manufacturing installation that uses following printed layers, this printed layers has comprised the groove part with pattern form, and it is except the color filter substrate for the manufacture of having superior quality is also for saving time and cost.
Printed layers 11 can have the thickness being restricted to from the border between carrier layer 12 and printed layers 11 to groove part 111.Printed layers 11 can have the thickness of about 0.1mm to about 1.0mm, but is not limited to this.
Printed layers 11 can be formed by organic polymer, and this organic polymer has and black cohesive, for blanket provides permanance, is not easy China ink or solvent absorption in printed layers, and easily the China ink being filled in groove part 111 is transferred on substrate 4.
This organic polymer can comprise siliceous organic polymer---for example dimethyl silicone polymer (PDMS), or comprise the organic polymer being formed by polyurethane material.Preferably, this organic polymer can be siliceous organic polymer.
In addition, the invention provides the printed layers 11 that further comprises coat 114.
Particularly, in the time that China ink is attached to the jut 112 of printed layers 11, except being filled into the China ink in the groove part 111 with pattern form, the China ink being positioned on jut 112 also can be transferred on substrate 4.Thereby, can produce less desirable defective pattern.In order to prevent defective pattern, as shown in Figure 2, can on the top surface of jut 112 113, arrange the coat 114 with China ink with low adhesion.Although show the coat 114 thicker than actual (real) thickness in order to represent the position of coat 114 in Fig. 2, coat 114 can have thin thickness.And, because coat 114 is included in the outer wall of groove part 111, the China ink of being not difficult fully to fill.
Coat 114 is by forming with China ink 31 materials with low adhesion.Thereby although China ink 31 discharges from exhaust unit 3, China ink 31 can not be attached to jut 112 yet.Therefore, China ink 31 is only attached to the groove part 111 with pattern form, to prevent from being formed with the pattern of defect.
Coat 114 can be to use solution---it significantly reduces the surface tension of the jut 112---formation that contains fluorinated surfactant, or uses the polymer solution prepared by the monomer with high fluorine content to form.But the present invention is not subject to the restriction of the material of coat 114.

The polymkeric substance of being prepared by the monomer with high fluorine content can use and well known to a person skilled in the art material.The example of described polymkeric substance can comprise: polytetrafluoroethylene (PTFE), fluorinated ethylene propylene copolymer (FEP), tetrafluoroethene perfluor (alkyl vinyl ether) multipolymer (PFA), ethylene tetrafluoroethylene copolymer (ETFE) and ethene chlorotrifluoroethylene (ECTFE).
Have the process of groove part 111 of pattern form except forming, can manufacture by conventional manufacture method according to printed layers of the present invention.For example, comprised the manufacture process of the printed layers 11 of the groove part 111 with pattern form with reference to Fig. 3 explanation.Manufactured the substrate 6 for module with roughness, described roughness has pattern form.Organic polymer is coated in to the substrate 6 for module, then solidifies.After organic polymer solidifies, in the time that organic polymer layers separates with the substrate 6 for module, can manufacture the printed layers 11 that has comprised the groove part 111 with pattern form.
Referring to Fig. 1, in carrier layer 12, form the printed layers 11 that has comprised the groove part 111 with pattern form.
Carrier layer 12 can be carried printed layers 11 and cushion 13.Carrier layer 12 can be formed by following film (film), and this film has low elasticity to suppress the contraction of printed layers and cushion, to improve printing precision.Particularly, carrier layer 12 can be by having approximately 1,000MPa or larger---preferably approximately 2,000MPa is to approximately 5,000MPa---stretch modulus (tensile modulus) film formed.The known resin molding that meets above-mentioned condition can be used as described film before this.The example of described film can comprise: for example polyethylene terephthalate of polyester film (PET), polycarbonate membrane (polycarbonate film), high density polyethylene (HDPD) film and polypropylene (PP) film.
The present invention is not subject to the restriction of the thickness of carrier layer 12.For example, the thickness that carrier layer 12 can have about 0.1mm to about 0.5mm---preferably about 0.2mm is to about 0.45mm---.In the time that the basic material (base material) of carrier layer 12 has than the little thickness of the thickness in above-mentioned scope, may be not enough to strengthening and carrying cushion or printed layers.On the other hand, in the time that the basic material of carrier layer 12 has than the large thickness of the thickness in above-mentioned scope, blanket can have thick thickness so that described blanket is not rolled around print roller.
Referring to Fig. 1, on cushion 13, form carrier layer 12.
When printed layers 11 has inhomogeneously when surperficial, cushion 13 can compensate the thickness difference of printed layers 11.Similar with printed layers 11, cushion 13 can have the foam texture being formed by PDMS material or the foam texture being formed by polyurethane material, but is not limited to this.
The present invention is not subject to the restriction of the thickness of cushion 13.For example, the thickness that cushion 13 can have about 0.05mm to about 2mm---preferably about 0.3mm is to about 1mm---.In the time that cushion 13 has than the little thickness of the thickness in above-mentioned scope, corresponding cushion 13 may be difficult to obtain enough impression pressure and adjust effect.On the other hand, in the time that the basic material of cushion 13 has than the large thickness of the thickness in above-mentioned scope, described basic material has relatively little thickness.Thereby the supporting effect between basic material layer may be impaired.
The printed layers 11 that has comprised the groove part 111 with pattern form is formed in carrier layer 12.Cushion 13 is formed on the surface opposing with the surface that is furnished with printed layers 11 of carrier layer 12, to form blanket 1.Blanket 1 can be rotatable on substrate by print roller 2.
Particularly, referring to Fig. 4, print roller 2 is around there being blanket 1, to make blanket 1 rotatable on substrate 4.That is to say, the cushion 13 of blanket 1 is around the surface of print roller 2.
As known before this, print roller 2 is to be formed by the metal of stainless steel (SUS) material.The present invention is not subject to the length of print roller 2 and the restriction of diameter.For example, print roller can have following length, approximately 1.1 times to approximately 1.3 times of the width that this length is used substrate.And print roller 2 can have following diameter, this diameter makes approximately 1.1 times to approximately 1.5 times of length that the girth of print roller 2 is used substrate.In the time that print roller has than the length in above-mentioned scope and the little length of diameter and diameter, the undergage that is wound on the printed layers in print roller with by design transfer to the whole surface of substrate.On the other hand, in the time that print roller has than the length in above-mentioned scope and the large length of diameter and diameter, printed layers has the wide size than needs, thereby has reduced efficiency.
In the time that the print roller 2 that blanket 1 is reeled is rotated on substrate 4, substrate 4 is advanced with the direction of the sense of rotation corresponding to print roller 2.At this, because the printed layers 11 of blanket 1 contacts with substrate 4, the China ink 31 being filled in the groove part with pattern form 111 of printed layers 11 can be transferred on substrate 4.
In process in the groove part 111 of China ink being transferred to blanket 1, blanket 1 can the speed rotation to about 200mm/s with about 10mm/s.In the time that blanket rotates with the little speed of the speed than in above-mentioned scope, more than China ink 31 may be discharged into the height of jut 112.Thereby China ink may be attached to jut 112, thereby produce defective pattern.In addition, may spend the long time China ink is filled in groove part 111, thereby increase the processing time.On the other hand, in the time that blanket rotates with the large speed of the speed than in above-mentioned scope, China ink 31 may be filled in groove part 111 fully.Thereby the pattern 5 of expectation may not be transferred on substrate 4.And pattern being transferred to from blanket in the process substrate, blanket can the speed rotation to about 200mm/s with about 10mm/s.And, when blanket is during with the rotation of the little speed of the speed than in above-mentioned scope, may spend the long time by design transfer to substrate.Thereby the processing time may increase.On the other hand, in the time that blanket rotates with the large speed of the speed than in above-mentioned scope, pattern may transfer to be shifted by halves due to the fast rotary of blanket.In addition, the shape of pattern to be transferred may be out of shape.
China ink 31 discharges from exhaust unit 3.China ink 31 is only discharged in groove part 111, and is not discharged on the jut 112 of printed layers.
The thickness of considering China ink 31, exhaust unit 3 can be arranged to the distance predetermined with blanket 1 interval.Can will can discharge black unit as exhaust unit 3.For example, can be by the exhaust unit that pattern of fever or piezo-electric type nozzle are housed as exhaust unit 3.
As mentioned above, the invention provides a kind of color filter substrate manufacturing installation that can manufacture the color filter substrate with superior quality.This device comprises: blanket 1, and it comprises printed layers, defines the groove part with pattern form in described printed layers; Print roller 2, it rotates blanket 1 on substrate; And exhaust unit, it is for being filled into China ink the groove part 111 with pattern form.
Thereby, use this color filter substrate manufacturing installation, can manufacture the color filter substrate with superior quality.Referring to Fig. 4, the China ink discharging from exhaust unit 3 is filled into the groove part with pattern form 111 of blanket 1.At this, the print roller rotation of coiling blanket 1, to be filled into China ink in the groove part with pattern form 111 of blanket 1.
In the time filling China ink, China ink 31 is filled along a direction of blanket 1, and China ink shifts along another direction of blanket 1 simultaneously.That is to say, the filling of China ink and transfer can be carried out simultaneously.Or, after China ink 31 is filled in the groove part 11 of blanket 1 completely, prepare substrate 4.Then, China ink 31 is transferred on substrate 4.That is to say, the filling of China ink and transfer can separately be carried out.
The print roller 2 that is wound with the blanket 1 that is filled with China ink 31 is rotated to the speed of about 200mm/s with about 10mm/s on substrate 4, and substrate 4 is along advancing with the corresponding direction of sense of rotation of print roller simultaneously.
In the time that the print roller of coiling blanket 1 is rotated on substrate 4, the printed layers 11 of blanket 1 contacts with substrate 4.In the time of printed layers contact substrate 4, the China ink 31 being filled in the groove part with pattern form 111 of printed layers 11 is transferred on substrate 4.Thereby, in the case of not using discrete spacer, can on substrate 4, form the pattern 5 having with the 111 corresponding shapes of the groove part with pattern form of printed layers 11.
