Description
Technical field
The present invention relates to use ink jet printing method to make the apparatus and method of color filter substrate (color filter substrate).
Background technology
Usually, make through on a plurality of layers, forming pattern such as electronic equipments such as liquid crystal display device and semiconductor devices.Photoetching process is widely used in forming pattern up to now.
The following principle of photoetching process utilization: specific photoresist (photo resist) (being called " PR " hereinafter) is receiving the light time chemically reactive to change its proper characteristics (prosperity).Being used for the negativity of color filter (negative) photoresist, have only the part that is not exposed to light just to be melted and to remove, taken place crosslinked because be exposed to the part of light.Positivity (positive) photoresist in the metal electrode pattern that is used for semiconductor devices and TFT; Because being exposed to the part of light is decomposed to produce acid; Expose portion and expose portion have not occurred to the significant difference of the solubleness of developer, made and only melt and remove expose portion.Thereby, in photoetching process, can use optionally radiant light of mask to desired pattern, have the pattern that has identical shaped or anti-shadow shape with the pattern of this mask with formation.Photoetching process comprises: the PR coating procedure is used for PR is located at substrate; Exposure process is used to use optionally radiant light of mask; And developing process, PR or the PR of part that is not exposed to light of part that is used to use developer to remove and is exposed to light is to form desired pattern.Yet, in photoetching process, should make predetermined mask.And, under the situation of positive photoresist, should repeat chemical etching and stripping process as the subsequent process that is used to form metal electrode pattern.Thereby have limitation: manufacturing process possibly be complicated, and possibly produce a large amount of poisonous chemical wastes.Therefore, thus manufacturing cost possibly increase and weakens product competitiveness.
In order to solve photolithographic limitation, the roller print process (roll printing process) that has proposed a kind of use print roller (printing roll) is as the new method that is used to form pattern.In addition, actively carrying out and be used to use the relevant research of technology of ink-jet printing technology manufacturing color filter substrate.
Have various roll marks brush methods, but roll marks brush 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 printed panel with groove the unnecessary China ink of raking off then.Afterwards, the China ink that uses transferring roller will stay in the groove is transferred on the substrate to carry out printing process.Because China ink is to use transferring roller to transfer on the substrate, so used the area transferring roller corresponding with the area of desired display equipment.And, have under the large-area situation at display device, can carry out transfer process and once form pattern.The printing process that gravure process is known as a kind of being suitable for and can be applied to every field---for example publication, packing, viscose paper (cellophane), vinyl (vinyl), tygon (polyethylene) etc.---.And, studying the metal pattern that has redness, green or blue multicolour pattern and be formed for preventing occurring in the PDP display EMI screen layer of static that gravure process is used to form color filter.
But, in being used to form the typical gravure process of fine pattern, in large-scale substrate, carry out etching process on---for example glass substrate---forming groove, thereby make printed panel.Only some is transferred roller and transfers on the substrate because be filled into China ink in the groove, so possibly need a compressing process to guarantee to be formed into through transfer the homogeneity of the thickness of the pattern on the substrate extraly.As a result, gravure process can be useful on and form extensive pattern and have the pattern of shape of stripes, but is not suitable for forming fine pattern---the pattern of black matix of color filter (black matrix) or TFT substrate for example.In view of the above, anti-shadow lithographic process can be mainly used in and form accurate fine pattern.
According to anti-shadow lithographic process, different with gravure process, China ink is coated on the blanket (blanket), jut (protrusion) contact that has the printed panel of groove then is coated to the China ink on the blanket.Afterwards, the pattern part of not expecting is removed, the pattern part of staying on the blanket is transferred on the substrate to form desired pattern.And except the multicolour pattern of color filter, anti-shadow lithographic process can also form the fine pattern with different shape---for example BM and TFT.In addition, manufacturing cost can reduce, and throughput rate can improve.But, need have high-quality blanket and obtain fine pattern.And, the pattern that is difficult to keep having constant shape.
Under the situation of ink jet printing method, compare with roll marks brush method, because the diffusion of China ink can reduce material consumption.In addition, needn't make printed panel.Thereby ink jet printing method can be very effective to making the 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 continuation needs to study can make the method that the color filter with superior quality has the advantage of ink jet printing method simultaneously again more simply.

The present invention does not receive 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---.When cushion 13 had than the smaller thickness in the above-mentioned scope, corresponding cushion 13 possibly be difficult to obtain enough impression pressure adjustment effects.On the other hand, when the basic material of cushion 13 had than the big thickness of the thickness in the above-mentioned scope, said basic material had relatively little thickness.Thereby the supporting effect between the basic material layer maybe be impaired.
The printed layers 11 that has comprised the groove part 111 with pattern form is formed on the carrier layer 12.Cushion 13 is formed on the surface with the surface opposition that is furnished with printed layers 11 of carrier layer 12, to form blanket 1.Blanket 1 can be rotatable on substrate through print roller 2.
Particularly, referring to Fig. 4, print roller 2 is around there being blanket 1, so that blanket 1 is rotatable on substrate 4.That is to say that the cushion 13 of blanket 1 is around the surface of print roller 2.
As known before this, print roller 2 is that the metal by stainless steel (SUS) material forms.The present invention does not receive the length of print roller 2 and the restriction of diameter.For example, print roller can have following length, and this length is about 1.1 times to about 1.3 times of width of employed substrate.And print roller 2 can have following diameter, and this diameter makes that the girth of print roller 2 is about 1.1 times to about 1.5 times of length of employed substrate.When print roller has than little length of the length in the above-mentioned scope and diameter and diameter, the undergage that is wound on the printed layers on the print roller with design transfer to the whole surface of substrate.On the other hand, when print roller had than big length of the length in the above-mentioned scope and diameter and diameter, printed layers had the wide size than needs, thereby has reduced efficient.
When the print roller 2 of being reeled when blanket 1 was rotated on substrate 4, substrate 4 was advanced with the direction corresponding to the sense of rotation of print roller 2.At this, because the printed layers 11 of blanket 1 contacts with substrate 4, the China ink 31 that is filled in the groove part with pattern form 111 of printed layers 11 can be transferred on the substrate 4.
In the process in the groove part 111 of China ink being transferred to blanket 1, blanket 1 can be with the speed rotation of about 10mm/s to about 200mm/s.When blanket rotated with the speed littler than the speed in the above-mentioned scope, China ink 31 may be discharged into more than the height of jut 112.Thereby China ink may be attached to jut 112, thereby produces defective pattern.In addition, may spend the long time China ink is filled in the groove part 111, thereby increase the processing time.On the other hand, when blanket rotated with the speed bigger than the speed in the above-mentioned scope, China ink 31 may be filled in the groove part 111 fully.Thereby the pattern 5 of expectation may not be transferred on the substrate 4.And, pattern to be transferred to from blanket the process on the substrate, blanket can be with the speed rotation of about 10mm/s to about 200mm/s.And, when blanket with than the rotation of the little speed of the speed in the above-mentioned scope time, may spend the long time with design transfer to substrate.Thereby the processing time may increase.On the other hand, when blanket rotated with the speed bigger than the speed in the above-mentioned scope, pattern may be shifted owing to the fast rotational of blanket by halves.In addition, the shape of pattern to be transferred may be out of shape.
Consider the thickness of China ink 31, exhaust unit 3 can be arranged to the distance predetermined at interval with blanket 1.Can be with the unit that can discharge China ink as exhaust unit 3.For example, can be with the exhaust unit that pattern of fever or piezo-electric type nozzle are housed as exhaust unit 3.
As stated, the invention provides a kind of color filter substrate manufacturing installation that can make color filter substrate with superior quality.This device comprises: blanket 1, and it comprises printed layers, defines the groove part with pattern form in the said printed layers; Print roller 2, it rotates blanket 1 on substrate; And exhaust unit, it is used for China ink is filled into the groove part 111 with pattern form.
Thereby, use this color filter substrate manufacturing installation, can make color filter substrate with superior quality.Referring to Fig. 4, the China ink that discharges from exhaust unit 3 is filled into the groove part with pattern form 111 of blanket 1.At this, the rotation of the print roller of coiling blanket 1 is in the groove part with pattern form 111 that China ink is filled into blanket 1.
When 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 that the filling of China ink and transfer can be carried out simultaneously.Perhaps, after black 31 complete filling are in the groove part 11 of blanket 1, preparation substrate 4.Then, China ink 31 is transferred on the substrate 4.That is to say that 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 on substrate 4 to the speed of about 200mm/s with about 10mm/s, and substrate 4 is along advancing with the corresponding direction of the sense of rotation of print roller simultaneously.
When the print roller of coiling blanket 1 was rotated on substrate 4, the printed layers 11 of blanket 1 contacted with substrate 4.When printed layers contact substrate 4, the China ink 31 that is filled in the groove part with pattern form 111 of printed layers 11 is transferred on the substrate 4.Thereby, under the situation of not using discrete spacer, can on substrate 4, form the pattern 5 that has with the 111 corresponding shapes of the groove part with pattern form of printed layers 11.
As stated; Printed layers through having comprised groove part with band BM pattern, have redly, the printed layers of the groove part of green, blue honeycomb pattern and the color filter manufacturing installation of printed layers with groove part of band column spacer patterns, can be simply be formed with the color filter of black matix (BM), redness, green, blueness, external application (over coat) and column spacer patterns on it with the quality manufacturing of excellence.
