[Prior Art] Liquid crystal displays (LCDs) are widely used in various electronic products such as TVs, surveillance IIs, notebook computers, and mobile phones. Driven by the market demand of strong edge, the LCD panel is gradually developing towards a large-scale trend. The system's systemic complexity and cost are increasing. Because the market is more vocal, the price becomes a consideration for consumers to purchase. Therefore, In order to achieve the goal of large dust and low cost at the same time, it is important to make innovations in the production technology of liquid crystal panel components. Among them, the technology of the color filter that accounts for a considerable part of the cost of the liquid crystal panel has become the focus of the panel makers and related manufacturers. The photoresist coating system of the three primary colors of 〇红绿蓝(RGB) is One of the important steps in the production of color filters, inkjet printing is currently the photoresist coating technology for emerging applications; I standard, can complete the three primary color coating, and does not require the complicated lithography process. As the inkjet printing method has many advantages, such as process simplification, material cost reduction and production efficiency improvement, it has gradually become the mainstream process. However, photoresist coating by inkjet printing method still has to be overcome. For example, the more the halogen, the smaller the area of each 昼$ area on the color filter. If the ink droplets of the inkjet ink cannot be accurately injected into the predetermined halogen region, and the other ink regions are lost, the color mixture defect will occur. . Therefore, when using the inkjet printing 1355295 brush method, the fresh (four) i ink-like coffee charm, the technology of the filter process.

[Embodiment] The present invention provides an ink jet head and a method of forming the ink jet head, which are applied to an ink jet printing method of a color filter 'light sheet, which can prevent a substance such as a photoresist from accumulating to generate a precursor. In order to provide a more uniform surface finish, the ink jet head of the present invention has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing a first embodiment of an ink jet head according to an embodiment of the present invention. In the illustration, the ink jet head 10 has an ink injection hole 12, and an arrow indicates the flow of the ink 6 path. After the ink enters the ink jet head 10 from the ink injection hole 12, it flows from the center to the both sides along the different flow paths. Each ink flow path has a corresponding outlet. Figure 2. The partial structure of the inside of the ink nozzle K). The ink blasting has a plurality of flow paths of a plurality of discharge units 40 corresponding to a plurality of numbers (please refer to Fig. 3 first), and the orifice sheets 60 are correspondingly disposed below the discharge unit 4''. The flow path unit % is preferably a channel-like groove 'for the ink to circulate. The flow path units 3G of the present embodiment are each independently arranged and arranged in parallel at intervals on the both sides of the same-side flow path unit 30, and the unit 3's on the side is set to be misaligned. The ejection unit is actually formed in the bottom hole of each of the flow elements 30 to cause the ink core to abut the flow path unit 30. Fig. 3 is a schematic view showing the distribution of the nozzle head unit 1 corresponding to the nozzle outlet unit 40 outside the bottom of the flow path unit 3''. As can be seen from the figure, the plurality of ejection units 40 of the present embodiment are turned in a straight line. However, the ejection unit 4() may have other arrangement modes. The embodiment of the present embodiment is not intended to limit the scope of the present invention. Further, in the ink jet apparatus to which the ink jet head 10 of the present invention is applied, an orifice sheet 60 (shown in FIG. 1) is disposed under the ink jet head 10, and a plurality of holes are distributed on the surface thereof, and each of the holes corresponds to each of the jets. Unit 4〇 settings. 4 is a cross-sectional view of the ink jet head 1 of FIG. 2 taken along a line A_A. The cross-sectional structure of the ink tank 2, the flow path unit 3, the discharge unit 4, and the orifice sheet 60 inside the ink jet 10 can be seen from the figure. The accommodation space surrounded by the outer casing of the ink jet head 1 constitutes the ink tank 2G and the flow path unit 3G, respectively. The ink tank 20 is a cavity located at the position corresponding to the ink 'main entrance hole 12 and above the flow path unit 30, and the flow path units are channels spaced apart from each other (as shown in Fig. 2). The ink tank 2 is connected to the end of the flow path unit 30, and the discharge unit 40 is connected to the other end of the flow path unit 30. The mouthpiece unit 40 is formed at the bottom of the flow path unit 3(). The ink substance of the present invention is injected into the ink tank 20 from the ink injection hole 12, and the ink flows through the flow path unit and is bottomed. The ejection unit 40 of P is ejected through the orifice sheet 60 out of the ink nozzle 1 . Please refer to phase 2 and Fig. 4 at the same time, and the flow path unit 3G is substantially surrounded by the inner wall surface 301 of the flow path. As shown in Fig. 4, the inner wall surface 301 of the flow path is formed with a liquid, and the lag 1 GG is in contact with the ink flowing therethrough. The material of the ink tank 20, the flow path unit 30, and the discharge unit 4 of the present invention is generally made of a metal material, and if the steel is not recorded, the village is called a gold-like substance to constitute the ink head of the present invention. The liquid detachment layer 1GG is an oleophobic material, and is preferably coated or mixed on the inner wall surface 301 of the flow path. Please refer to Figure 5, the liquid is separated from the 1G and the oily liquid has a liquid contact angle ~. The contact angle here is defined as the angle at which the liquid surface is given—the angle lost when the body surface is in contact' and is the angle between the sharp and the side. If the angle between the liquid surface and the surface of the IU body is larger, the force acting inside the liquid is greater than the force acting on the liquid and the solid surface. In this example, as shown in Fig. 5, the oleophobic liquid detachment layer 1 〇〇 is in contact with the oily liquid. - Generally speaking, the system is greater than 9 inches. . In this way, the oily liquid tends to aggregate into a water droplet shape on the inner wall 3()1 of the flow path having the liquid detachment layer instead of being flattened on the inner wall surface 3〇1 of the flow path. The oleophobic hoof quality of the liquid detaching layer 100 of the present embodiment is preferably a chemical material having a high polarity, for example, a vaporized 'common one is, for example, iron Wei (5) lanthanum (6), and the carbon between the sub-sections is strong. . In this case, Teflon is applied to the inner wall surface of the flow channel. In another example, the carbon tetrafluoride ((5) is deactivated on the inner wall surface of the flow channel of the non-metal material as the liquid detachment layer (10) by an AP plasma surface treatment technique. In another embodiment, the liquid is detached. The layer 100 may be a hydrophobic material and may be coated or otherwise covered on the inner wall surface 3Q1 of the flow channel. The liquid contact angle of the liquid detachment layer 100 of the present embodiment and the aqueous liquid is generally greater than 9 〇. Similar to the above implementation For example, in this example, the aqueous liquid tends to aggregate into a water droplet shape on the inner wall surface 301 of the flow channel having a liquid detachment layer, instead of being flattened on the inner wall surface 301 of the flow channel. The hydrophobic material used in this embodiment is ― Generally speaking, it is a chemical material that has no polarity or low polarity, such as polyester/azaki/polypropylene eye. The common material is ? (four) thin (PET), and the material is compatible with aqueous liquid (such as water). Hydrogen bonds are generated, and the aqueous liquid repels the material and generates a chlorine bond by itself, so that the aqueous liquid polymerizes into a droplet on the surface of the material. Further, as shown in FIG. 4, the ink jet head 1 in this embodiment Ink The groove 20 has an ink tank inner wall surface 2 (n, and the discharge unit 4A has a discharge unit inner wall surface 401. The ink tank inner wall surface 201 and the discharge unit inner wall surface 4〇1 also form a liquid detachment layer 100 thereon. The ink tank inner wall surface The liquid contact angle of the liquid detachment layer 100 on the inner wall surface 4〇1 of the ejection unit is greater than a specific angle. In short, if the ink jet head 1 of the present invention is used for the oil supply liquid (ink), The liquid detachment layer 1 formed on the inner wall surface 201 of the ink tank and the inner wall surface 〇1 of the discharge unit is an oleophobic material, and the contact angle with the oily liquid is generally greater than 9 〇. When the head 10 water-supply liquid (ink) is used, the ink tank inner wall surface 201 and the liquid detaching layer 1 formed on the inner wall surface 401 of the discharge unit are hydrophobic materials, and the contact angle with the aqueous liquid is generally greater than 90. However, in other embodiments, the inner wall surface of the ink tank and the inner wall surface of the discharge unit may also be changed without having a liquid detachment layer. The ink jet head 10 of the present invention is another embodiment. Runner unit 30 The transfer polishing layer is formed on the inner wall surface 301 of the flow channel. In other words, the polishing polishing layer formed by the polishing is used as the liquid detachment layer. The roughness of the polishing and polishing layer is preferably less than 40 μm (Qm). The smaller the surface roughness, the representative The smoother the surface, the smoother the inner wall surface 3〇1 of the smoother polishing layer is, the less likely it is to adhere to foreign substances. Generally, the polishing layer is formed on the inner wall surface of the flow channel for physical and chemical properties. Or other methods of polishing and grinding, so that the roughness of the inner wall surface 301 of the flow channel is reduced. In different embodiments, after the polishing layer is formed on the inner wall surface 301 of the flow channel, the liquid separation layer is further coated on the polishing layer. 1GG' means that the ink nozzles are divided into polished and smeared coatings (or bismuth ore) to achieve better ink repellency. Figure 6 is a flow chart showing a method of forming the ink nozzle of the present invention. As shown in Fig. 6, the first step is to form the ink groove to accommodate the ink, and the flow path 7G-end is turned on to the ink tank to supply the ink. Actually, the ink jet head having the housing space formed by the outer casing 11 constitutes the ink tank and the flow path unit, respectively, and the flow path unit formed in this step has the inner wall surface of the flow path. _, step by step to form a liquid detachment layer on the inner wall surface of the flow channel. In general, this step is preferably to form a liquid detachment layer on the inner wall surface of the flow path by coating or by means. , - Implementing the wealth, forming (four) the steps of the lining layer to remove the oleophobic material to form the liquid detachment layer. The liquid detachment layer of this embodiment is generally greater than 9Q with respect to the liquid connection of the oily liquid. The poor quality of the materials is 10 questions [chemical materials of raw materials. A commonly used oleophobic material is, for example, a vapor, and a common one is, for example, Teflon, which has a strong fluorocarbon bonding force between molecules. However, the other side of the secret #f can also be used by H to form a liquid core separation step 1003 gamma X hydrophobic material is applied to the inner wall of the flow channel to open the liquid 4 from the layer. The liquid contact angle of the liquid application is generally greater than 90. . The hydrophobic material is a chemical material that does not have a polarity or a low polarity, such as polyg/polypropylene/poly-eye, and the common material is polypropylene (PET). Further, in the embodiment, the step of forming the ink jet head further comprises the step of performing a mopping process on the wall surface of the fluid, so that the roughness of the inner wall surface of the flow channel becomes small, and the solid 4G micron (_). After polishing and repairing the inner wall surface of the flow channel, a polishing and polishing contact is formed. After the polishing layer is formed on the inner wall surface of the flow channel, a liquid detaching layer is further coated on the polishing polishing layer, which is separately polished and coated ( Or bribe) to achieve a better ink-repellent effect. In the alternative embodiment, however, the step comprises the formation of a polishing layer, and the polishing layer acts as a liquid detachment layer. In addition, the method for forming an ink jet head according to the embodiment further includes the steps of: forming a discharge unit at the other end of the flow path unit. The 'actual' ejection unit is formed in the flow channel unit - the end closing hole for supplying ink. ejection. It should be noted that the step 脳 and the step (10) step are not performed in an absolute order. For example, the step 1005 of the embodiment may be performed before step 1001 or simultaneously with step 1001. As described in the above embodiments of the present invention, the ink jet head provided by the present invention has a liquid detaching layer 'having a characteristic that the inside thereof is not easily stained with I 纟 ink, and the residual slag remains in the ink jet head, thereby providing Excellent inkjet accuracy and long life. The present invention has been described by the above-described related embodiments, but the above embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of this judgment. On the contrary, the spirit and the modifications and equivalents of the invention are included in the scope of the invention. [Simple description of the map]
