background

  In the flat panel display industry, attempts have been made to use inkjet printing to produce display devices, particularly color filters. One problem with efficiently utilizing ink jet printing is that ink or other material is accurately ink jetted onto a substrate while at high throughput. In some cases, for example, ink droplets may not fall accurately into the pixel wells of the substrate. There is a need for a method and apparatus for improving the quality of color filters manufactured using high throughput ink jet printing.

  Other features and aspects of the present invention will become more apparent from the following detailed description, claims and accompanying drawings.

Detailed description

  Flat panel display manufacturing uses color filters that contain different colored inks printed on a glass (or other material) substrate. The ink is deposited using an ink jet printer that causes the ink and / or other suitable material to be accurately ejected into a specific pixel well defined by a pixel matrix (commonly referred to as a “black matrix”). . Prior to ink deposition, a black matrix of pixel wells is formed on the substrate using lithography or any suitable process.

  Materials that come into contact with the liquid react to attract or repel the liquid. The composition of the material, its corresponding surface chemistry, and liquid chemistry determine the interaction with the liquid. This phenomenon is called hydrophilicity (for example, the same as the ink affinity of liquid ink) and hydrophobicity (for example, the same as the ink-phobic property of liquid ink).

  Hydrophilicity is a property of a material that exhibits an affinity for water. Hydrophilic literally means “easy to adapt to water” and such materials readily adsorb water. By surface chemistry, these materials wet and form a liquid film or coating on the surface. Hydrophilic materials also have high surface tension values and have the ability to form bonds with water.

  Hydrophobicity is a property of a material that has an opposite reaction to interaction with water compared to a hydrophilic material. Hydrophobic materials (“fearing water”) have little or no tendency to adsorb water, and water tends to “ball-like” on its surface (eg, form individual droplets). . Hydrophobic materials have low surface tension values and are free of active groups to form bonds with water in their surface chemistry.

  In some cases, a single material may be “friendly” to, for example, an aqueous liquid, for example, “loose” to an oil-based liquid. Or the reverse may be sufficient. As used herein, hydrophilicity, ink affinity, hydrophobicity and ink repellency are intended as relative terms, and the material is inkphobic for some inks and not for other inks. May be ink-philic. Furthermore, just because a material is hydrophilic does not mean that the material is inkphobic. Similarly, just because a material is hydrophilic does not mean that the material is ink-philic. Thus, for example, the material may be hydrophobic and simultaneously ink-philic or simultaneously ink-phobic. For example, the ink may be oil-based or water-based.

  Wettability refers to the surface properties of a material that give a value to each compound. Wetting is the contact between the fluid and the surface when in contact. When the liquid has a high surface tension (strong internal bond), droplets are formed, while the low surface tension liquid spreads over a large area (bonds to the surface). On the other hand, if the surface has a high surface energy (or surface tension), the droplet spreads or wets the surface. If the surface has a low surface energy, droplets are formed. This phenomenon is a result of minimal interfacial energy. If the surface is high energy, this interface will reduce its energy, etc., so it is not necessary to be covered with a liquid. By utilizing the surface tension value of the material, the wettability of the material by a specific liquid can be determined. By measuring the contact angle between the solid surface and the liquid droplets on the surface, the surface tension of the solid material can be calculated.

  Surface tension (or energy) refers to the force obtained by molecular force non-equilibrium that occurs when two different materials (eg, droplets on a solid surface) come into contact with each other to form an interface or boundary. Point to. This force is due to the tendency of all materials to reduce their surface area, corresponding to the molecular force non-equilibrium that occurs at the point of contact. The result of this force varies for different systems of liquid and solid, which determines the wettability and the contact angle between the droplet and the surface.

  For a droplet with a solid surface, the contact angle is a measurement of the angle formed between the surface of the solid and the tangent to the droplet radius from the point of contact with the solid. The contact angle is related to the surface tension according to the Young's equation, which can calculate the behavior of a particular liquid-solid interaction. When the contact angle is zero, the liquid becomes wet, and when the angle is between zero and 90 degrees, the droplet spreads (due to molecular attraction). Angles greater than 90 degrees indicate that the liquid tends to bead or shrink on the solid surface. A contact angle of 90 ° or greater indicates that the surface is not wet, and less than 90 ° means that the surface is wet. In relation to water, wetted surfaces are also called hydrophilic and non-wettable surfaces are also called hydrophobic. Similarly, in the context of ink, wetted surfaces are also referred to as ink repellency, and non-wetting surfaces are also referred to as inkphobic. The ultra-sparse surface has a contact angle greater than 150 °, indicating little contact between the droplet and the surface. This is sometimes referred to as the “Lotus effect”. This property spreading over a large area is sometimes referred to as “wetting action”.

  The cross-sectional shape (eg, distribution) of the ink droplets that adhere to the pixel wells may form a color filter due to changes in the ink affinity / ink repellency of the material used to form the substrate and / or black matrix. Not optimal for. In some cases, a non-uniform distribution of ink within the pixel well can be a color filter defect.

  Usually, the black matrix is a pigment dispersion additive, an initiator, a polymerizable monomer or oligomer, or a combination thereof (for example, a photopolymerizable monomer, a thermally polymerizable monomer, etc.), a binder resin, an epoxy monomer, and a solvent. It is formed from the composition containing this. The method and apparatus of the present invention provides a black matrix composition comprising a wetting additive that improves the wettability of the black matrix. For example, in certain embodiments, the wetting additive may be used while changing (eg, decreasing) the ink repellency of the sidewall surface of each pixel well defined by the black matrix or changing the ink affinity (eg, increasing). However, the ink sparseness of the surface of the upper surface of the black matrix, the upper part of each pixel well, and the like may be increased. Such a black matrix composition reduces mixing of color inks during inkjet, improves ink distribution within each pixel well, and improves color filter fill cross section and color contrast. More specifically, ink that falls unintentionally on the top surface of the pixel matrix sinks into the pixel well and wets the sidewalls well. This tendency to sink into the pixel wells of the ink of the present invention reduces the accuracy required for printers that dispense ink.

  In one or more embodiments, the wetting additive comprises any material having polymerizable molecules, each with both a relatively ink-philic polar portion and a relatively ink-phobic non-polar portion. Good. For example, such materials may include monomers and / or oligomers containing one or more hydrophobic groups, such as fluorinated acrylate monomers and / or oligomers, silicone group-containing acrylate monomers or oligomers, other acrylate monomers and / or oligomers, reactive Waxes and / or fluorosilanes may be included. Polymerization is a process in which monomer and / or oligomer molecules are reacted by a chemical reaction to form a three-dimensional network structure or polymer chain. As described below, these wetting additives may be used, for example, instead of epoxy monomers to “activate” by a curing step that concentrates the ink-phobic ends of the additive molecules on the top surface of the black matrix. The patterning forms a black matrix having an ink-phobic planar pixel well (upper) surface and ink-philicity (eg, with respect to the upper plane of the black matrix) pixel well sidewall surface.

  Exemplary black matrix compositions according to the present invention, methods for forming the same, and methods for manufacturing a black matrix are described below with reference to FIGS. For example, FIG. 1 illustrates a method 101 for producing a black matrix on a substrate according to an embodiment of the invention. Referring to FIG. 1, in step 105, a black matrix composition including a wetting additive is formed. For example, a black matrix composition may contain wet additives such as hydrophobic group-containing monomers or oligomers (eg, fluorinated acrylate monomers or oligomers, silicone group-containing acrylate monomers or oligomers, acrylate monomers or oligomers containing other groups, etc.). May be included.

  The black matrix composition may contain other components such as a pigment dispersion, an initiator (for example, a photoinitiator), a polymerizable monomer, a binder resin, a solvent, and the like. A pigment (for example, carbon black) is dispersed throughout the black matrix composition, including the pigment dispersion. An initiator is included to aid the polymerization reaction (eg, photopolymerization reaction, thermal polymerization reaction or other feasible reaction). Including a polymerizable monomer (or oligomer), the composition may be polymerized to form a black matrix. Examples of such molecules include acrylate monomers / oligomers and epoxy monomers / oligomers. A binder resin may be included to provide a black matrix structure, stiffness and strength. An example of such a binder resin is an acrylate binder. Solvents may be included to temporarily reduce the viscosity of the composition (eg, until the solvent evaporates) to assist in applying the composition to the substrate (eg, spin coating or slit coating methods). make use of). Examples of such a solvent include any suitable solvent such as propylene glycol monomethyl ether acetate (PGMEA) or an organic solvent.

  In at least some embodiments, the black matrix composition comprises a wetting additive (comprising polymerizable molecules having both an ink-philic polar portion and an inkphobic non-polar portion) about about 1% of the total composition without solvent. It may be included at a concentration of 100 to about 10,000 ppm by weight. In certain embodiments, the concentration of the wetting additive is preferably in the range of about 500 ppm to 5,000 ppm by weight of the total composition without solvent. However, different concentration ranges of wet additives may be used. Further exemplary wetting additives include CN4000, CN9800, CN990, Degussa AG, Dusseldorf, Germany, manufactured by Sartomer Company Inc., Exton, Pa., Exton, Pa. One or more of the TEGO® Glide Series and / or the TEGO® Flow Series are illustrated. However, one or more additional and / or different additives may be used.

  The selection of a suitable wetting additive may be based on, for example, the molecular weight of the wetting additive, the hydrophobic group concentration, reactivity, and the like. In certain embodiments, the wetting additive may have a molecular weight in the range of about 100 Mw to about 100,000 Mw (weight average molecular weight). The weight average molecular weight is preferably in the range of 500 Mw to 10,000 Mw. However, wetting additives with higher or lower molecular weight and / or different molecular weight may be used.

  At step 107, a substrate is provided. For example, the substrate is glass, triacetyl cellulose (TAC), polycarbonate (PC), polyethersulfone (PES), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyvinyl alcohol (PVC), polymethyl methacrylate (PMMA). ), Cyclo-olefin polymer (COP) and / or other suitable materials. FIG. 2 is a cross-sectional side view of a substrate 201 processed by the method 101.

  In step 109, a layer 203 (FIG. 2) of black matrix composition 205 is formed on substrate 201. The black matrix composition layer 203 may be formed on the substrate 201 using a dipping method, a spray method, a spin and spin coating method, or other suitable methods. In this way, the substrate 201 is coated with the black matrix composition 205. The black matrix composition 205 may be dried by heating the substrate 201. Accordingly, the solvent in the black matrix composition 205 evaporates. This method of post-coating heating is referred to as a “soft bake” process.

  In step 111, activation energy is applied to the black matrix composition 205 to polymerize the wet additive, thus imparting polarity to the molecules of the wet additive and activating the ink-phobic portion of the molecule. To move towards energy. The polymerization may be performed using a viable activation energy source, depending on the composition 205. For example, ultraviolet light, electron beam irradiation, laser light, and / or a lamp may be used as the activation energy source. Other activation energy sources or combinations may be used.

  In some embodiments, in step 111, layer 203 of black matrix composition may be patterned. For example, as shown in FIG. 3, the mask 301 may be disposed (or formed) on the black matrix composition layer 203. Thereafter, the black matrix composition layer 203 may be irradiated through the mask 301 using UV or other wavelength light or energy 303. The energy 303 exposes the portion 305 of the black matrix composition layer 203, but does not expose the other portion 307 of the black matrix composition layer 203. It should be noted that in other embodiments, a negative mask in which the opposite portion 307 of the black matrix composition layer 203 is exposed to energy 303 may be used.

  When light (or other energy) of an appropriate wavelength strikes a part of the black matrix composition layer 203, the initiator in the black matrix composition 205 absorbs the light 303 (energy) and free radicals are exposed to the exposed part. Form molecules. The initiator may function as a polymerization initiator that polymerizes a polymerizable monomer in the exposed portion of the black matrix composition layer 203. Accordingly, such exposed portions of the black matrix composition layer 203 include a polymer obtained from the polymerization of polymerizable monomers. The polymerizable monomer of the wetting additive is fixed during such lithographic exposure.

  After the exposure, a development process may be performed on the substrate 201. For example, the exposed or unexposed portion of the black matrix composition layer 203 may be developed using a developing solution so that the portion is removed. For example, the binder resin contained in the exposed portion may react with the developing solution. FIG. 4 is an example of a cross-sectional view of the substrate 201 after development.

  The voids resulting from the removal of the developed portion are injected with ink via an ink jet when forming a color filter and act as pixel regions or wells 401 that define a black matrix 403.

  The substrate 201 may be further cured. For example, the substrate 201 may be exposed to heat or ultraviolet rays, electron beam irradiation, laser light, or the like, and the black matrix composition in the layer 203 may be cured and crosslinked to form a crosslinked resin in the black matrix composition layer 203. Good. As shown in FIG. 5, when energy 501 is applied to the black matrix composition layer 203, the ink-phobic nonpolar portion of the wet additive molecule rises to the upper surface 503 of the black matrix composition layer 203, and the black matrix composition layer An ink-phobic layer 505 is formed in the vicinity of the upper surface 503 of 203. This ink-phobic layer 505 may be relatively ink-phobic (eg, more ink-phobic than a black matrix material with or without a low concentration of wetting additive).

  As described above, the upper surface 503 of the black matrix 403 has ink repellency, and the side wall surface 507 (for example, the vicinity of the pixel region 401) of each pixel well formed in the black matrix has lower ink repellency than the upper surface 503. In some embodiments, it may be ink-philic. Accordingly, the top surface 503 of the black matrix prevents ink bleeding between adjacent pixel wells, thus preventing ink color mixing during the jet process and improving the pixel well fill profile (eg, pixel wells). More consistent and complete filling). This produces an improved color filter. For example, FIG. 6 is a side cross-sectional view of ink 601 in the pixel region 401 of the substrate 201 according to one embodiment of the invention. Referring to FIG. 6, the wet additive concentrated on the upper surface 503 of the black matrix 403 after curing renders the upper surface 503 ink-phobic, while the side wall surface 507 remains lowly ink-phobic and even ink-philic. . Thus, the ink 601 is separated like a ball from the upper surface 503 of the black matrix 403, and the ink 601 does not spread beyond the pixel region 401.

  Indeed, the migration of the wet additive may be a dynamic process that occurs during the entire pixel well formation process (eg, during formation of the black matrix composition layer on the substrate, during soft baking, during the UV curing process, etc.). In at least one embodiment, the soft bake time (in air) at a temperature of about 105 ° C. is about 1.5 minutes. UV curing (exposure) is about 30-60 seconds in air and final curing is about 10 minutes in air. For other bake and / or cure gas environments (eg, nitrogen, argon, etc.) other soft bake, UV cure and / or final cure times may be used.

  FIG. 7 illustrates an exemplary molecule 701 used as a wetting additive according to one embodiment of the present invention. Referring to FIG. 7, an exemplary molecule 701 includes a first end 703 that is oleophilic and / or reactive. Further, the exemplary molecule 701 includes an ink-phobic second end 705.

  FIG. 8 illustrates the orientation 801 of the exemplary molecule 701 of FIG. 7 in the black matrix composition 205 according to one embodiment of the present invention prior to curing (eg, prior to application of activation energy). Referring to FIG. 8, in the pre-curing orientation 801, the first and second ends 703 and 705 of the molecule 701 are substantially irregularly oriented, and the molecules are substantially uniformly distributed in the black matrix composition 205. .

  FIG. 9 illustrates an orientation 901 after curing (eg, after applying activation energy) of the exemplary molecule 701 of FIG. 7 in the black matrix composition 205 according to one embodiment of the present invention. Referring to FIG. 9, during the curing of the black matrix material, the molecules 701 rise to the upper surface 503 of the black matrix composition 205, and the ink-phobic ends 705 of the molecules 701 are exposed to the upper surface 503 (eg, a surface exposed with activation energy). Or the ink-phobic layer 505 described above. Accordingly, the upper surface 503 is more lyophobic than the sidewalls formed in the black matrix material.

Referring to FIGS. 10-12, the structural formulas of three specific examples of polymerizable molecules suitable for use as wetting additives according to the present invention are shown. FIG. 10 shows the structural formula of an exemplary wetting additive molecule 1000 (eg, acrylate) with a non-polar tail 1002 that includes an ink-phobic CF ₂ chain. The polar portion 1004 includes a carbonyl carbon atom that is double bonded to the first oxygen atom and single bonded to the second oxygen atom. The polar part 1004 is ink-philic. The molecule 1000 further includes a polymerizable portion 1006 that is also directly attached to the carbonyl carbon atom of the polar portion 1004. The polymerizable portion 1006 includes two carbon atoms that are double bonded to each other. FIG. 11 shows the structural formula of an exemplary wetting additive molecule 1100 with a nonpolar main portion. FIG. 12 shows the structural formula of an exemplary silicon polymer wetting additive molecule 1200.

  Conventional black matrix material formulations contain conventional ingredients such as monomers, oligomers / polymers, photoinitiators, pigments, solvents, and the like. When ink falls onto such a black matrix material, the ink contact angle at the top surface of the black matrix is less than about 5 degrees. In contrast, the inclusion of the additive of the present invention changes the ink contact angle at the top surface of the black matrix from about 10 to about 75 degrees, more preferably from about 25 to about 60 degrees. Using the concentration of the additive used and the processing conditions (eg, activity / exposure time and energy, other components, etc.), the contact angle can be adjusted to a more specific desired value within the above range (eg, about 28 degrees, About 35 degrees).

  The above description discloses only exemplary embodiments of the invention. Modifications to the apparatus and methods disclosed above that fall within the scope of the invention will be readily apparent to those skilled in the art. For example, the concentration of the pigment dispersion in the black matrix composition, the initiator, the polymerizable monomer, the binder resin and / or the solvent may be changed. Similarly, in some embodiments, the black matrix may be formed directly on the thin film transistor (TFT) of the flat panel display. Furthermore, the present invention may also be applied to processes of spacer formation, polarizer coating and nanoparticle circuit formation.
