The liquid crystal display panel can be roughly classified into a vacuum injection type and a liquid drop type (one drop fiU 〇 DF) according to the manner in which the liquid crystal molecules are filled. Vacuum injection means that the CF substrate and the TFT substrate are bonded together, and a small hole is left on the side of the CF substrate and the tft substrate, and then the liquid crystal molecules are slowly injected into the between the 〇7 substrate and the TFT substrate by capillary principle, but this is The seed aa/master mode is very time consuming. In the liquid crystal dropping type, the TFp substrate is coated with a layer-by-layer glue, and the liquid crystal molecules are dropped on the pixel region of the TFT substrate, and then the CF substrate and the TFT substrate are bonded. Compared with the vacuum injection method, the liquid crystal molecular layer can be filled by the liquid helium dropping type process, and the time can be shortened, and the amount of liquid crystal molecules can be effectively used.

The total number of diverting passages 118 is - the square of the natural number, for example, the outlet _ of the spray passage 118 can be arranged as a matrix of n X η and n is a natural number. Taking the embodiment as an example, the single sprinkler head ι 4 has four sprinkler channels 118, and the outlets of the sprinkler channels 118 can be arranged in a matrix of one (four) 其中 among the 'sprays; the diameter of the runners 118 is better. Both are smaller than the diameter of the distribution pipe 114 to obtain a minute volume of liquid crystal droplets. In addition, the outlets of the runners 118 are preferably spaced between about 丨 mm and 15 filaments to provide a better liquid crystal uniformity and reduce the travel of the drip device, so that the liquid crystal display can be rendered. Hook the brightness. When the exits of the jet inspection track 118 are arranged in a matrix of even-numbered even-numbered turns, each of the flow paths 118 may be an oblique flow path. When the nozzle is not shaken, since the dispensing tube 1 of the dropping device 102 has only a single liquid (four) port, the single liquid crystal dropping step will only be on the surface of the substrate 120 = a single liquid crystal droplet. Since the present invention drops the oral spray head just after dropping the bottom of the reading, the single liquid crystal dropping step is to form a plurality of fabrics on the surface of the soil board m. According to this, the hairspray can only use the spray head to make the volume of each liquid crystal droplet smaller, and can reduce the stroke and time of the dripping installation, and greatly improve the process efficiency of the liquid crystal dropping process. In addition, since the present invention uses the non-curved linear jet ii8 to spray the liquid crystal droplets, the liquid crystal material 116 in each of the sprays 'flow 118 can flow smoothly, and is not easily stuck at the fold, and The liquid crystal material 116 can be uniformly dispersed to the respective spray channels 118, and it is difficult to cause the liquid crystal droplets to be sprayed to be different due to the difference in shape or length of each of the spray channels 118. / In the foregoing embodiment, the outlet li8b of the spray channel 118 may be arranged in a matrix of η χ n such that the spray channel 118 is relatively uniform in length. In other embodiments, the spray 118 outlet 118b can also be routed to other configurations or shapes to accommodate different process requirements and panel designs. For example, the outlet 118b of the spray channel 118 can be arranged as a matrix of m χ n; it can be arranged along the periphery of a circle, a square, a rectangle, a triangle or other polygonal regions; it can be a circle, a square, a rectangle, a triangle or Other polygonal areas are equidistant, uniform or randomly arranged. The cross-sectional profile of the sprinkler head 104 is also not limited to the circular shape shown in the foregoing, but may be designed as a square, a rectangle, a triangle or other polygon depending on the process requirements or the configuration of the spray channel U8. For example, when the cross-sectional profile of the lion (1) 4 is square, rectangular, triangular or other polygonal shape, the side or the angle of the sprinkler head 1 〇 4 φ can be used to position the mounting direction of the sprinkler head 104, and the shape of the sprinkler head 104 can be It is suitable for a plurality of shower heads 1 to 4 to be combined with each other. Please refer to FIG. 5 to FIG. 1 , which are schematic views of a sprinkler head according to other preferred embodiments of the present invention, wherein FIG. 5, FIG. 7 and FIG. 9 are bottom views, and FIG. 6 Fig. 8 and Fig. 10 are perspective views. The spray heads 2〇4, 304, 404 of Figures 5 to 1 also respectively have a plurality of spray channels 218, 318, 418, wherein each spray channel 218, 318, 418 can be directly connected to the aforementioned drip. The dispensing tube 114' of the device and each of the spray channels 218'318, 418 are directly sprayed out of the liquid crystal material U6 without a bend. The exit 218b of the nozzle spout 218 of Figs. 5 and 6 can be arranged 7 201032900 3 χ 3 matrix. Wherein, the exit of the #喷喷道 can be arranged as a matrix of 'odd numbers', and the direction of the spray channel 218 located in the center can be perpendicular to the dispensing pipe 1〇4 of the drip device 102. The outlets 3 of the spray channel 318 of FIG. 7 and FIG. 8 may be arranged along the periphery of the regular hexagonal region 322. For example, the six outlet genus are respectively disposed at six apex positions of the positive six=, and the center is There may be another outlet 318b that is perpendicular to the drip device. At the same time, the outlet passages of the sprinkling channels 318 of Figs. 7 and 8 are also arranged equidistantly within the circular area 324. Accordingly, the arrangement of the outlet 318b of the squirting channel 318 can also be configured to correspond to the shape of the 头3〇4 to increase the utilization of the _3〇4 space, for example, although the showerhead 304 has a circular cross-sectional profile. At the time, the outlets 318b of the spray channels can be arranged equidistantly within the entire circular wear surface of the sprinkler heads 3〇4. The exit outlines of the sprinkler channels 418 of Fig. 9 and Fig. 10 can be arranged in a matrix of m x η, which are two different natural numbers, for example, a matrix of 2 X 3 . According to this, the setting of the outlet port of the spray channel 418 can also be adjusted and set in accordance with the aspect ratio of the liquid crystal display panel. For example, for a small-sized panel, the size of the spray head and the outlet of the spray channel can even directly correspond to the requirements of each panel, so that the single-time liquid crystal dropping step can complete the liquid crystal amount required for a single panel. Liquid crystal distribution. In summary, since the present invention installs a shower head having a plurality of liquid crystal discharge ports at the bottom of the dropping device, a single liquid crystal dropping step can form a plurality of liquid crystal droplets on the surface of the substrate, thereby greatly improving the liquid crystal dropping process. Process efficiency. In addition, since the present invention utilizes a straight line spray channel that is not bent to spray, the liquid crystal material is not easily stuck at the bend, and the liquid crystal material can be uniformly dispersed to the respective spray channels, which is not easy to be 8 201032900 because The difference in shape or length of each jet inspection channel leads to the liquid crystal droplets. The above is only a preferred embodiment of the present invention, and all the equivalent variations and modifications made by the patent application of the present invention are as follows.
