Improved coating device and coating method

The present invention relates to an improved coating apparatus and coating method.

More specifically, coating is performed by using a jig capable of receiving a plurality of substrates and by coating the entire surface, partially coating, dispersing coating, and partial and dispersion coating. The liquid is applied to a plurality of substrates, and the present invention relates to an improvement in the ability to manufacture substrates corresponding to various substrate sizes, remove dead zones of the substrate, significantly reduce overall manufacturing costs and tact time, and easily satisfy market/customer preferences or tastes. Coating device and coating method.

In general, a coating device for applying a coating liquid onto a substrate such as glass by using a nozzle dispenser or a squeeze nozzle (hereinafter generally referred to as a "nozzle device") to manufacture a PDP including electricity A flat panel display (FPD) such as a plasma display panel, an LCD (Liquid Crystal Display), and an OLED (Organic Light Emitting Diode).

More specifically, Figure 1a schematically illustrates a coating apparatus for fabricating a PDP or LCD in accordance with the prior art.

Referring to FIG. 1a, in a flatbed coater (hereinafter referred to as "coating device") 100 to be used for manufacturing an FPD, a coating method using a coating liquid is used, which comprises, for example, forming a The operation of the pixels of the R, G, and B cells formed on the substrate G, or the operation of applying the protective coating layer for protecting the plurality of coating layers, the protective coating layers are successively formed on the substrate G or the like, while the substrate G is positioned on the suction platform 112, a nozzle device 120 attached to the holder 125 is moved in the horizontal direction.

More specifically, first, it is necessary to transport the substrate G onto the suction platform 112 to apply a coating liquid onto the substrate G. After that, the substrate G is maintained on the suction platform 112 by a suction region (not shown) formed on the suction platform 112 and a vacuum device (not shown) connected to the suction region. An empty suction state. Thereafter, the coating liquid system is applied to the substrate G through the discharge portion 122 formed at the bottom of the nozzle device 120.

Figure 1b schematically illustrates a top view and a side view showing the coating apparatus illustrated in Figure 1a.

Referring to FIG. 1b, in a coating method using a coating apparatus 100 according to the prior art, the nozzle device 120 applies a coating liquid on an entire surface so as to form a coating layer 130 while the nozzle device 120 is The substrate G is moved in the direction indicated by the arrow. When the entire surface coating of the coating liquid is completed, it is possible to obtain the plurality of panels P by cutting the substrate G to a desired size. More specifically, in the event that the substrate G is, for example, a high definition television (HDTV), the plurality of panels for the television are cut to the desired size by the substrate G (for example, 40 吋, 50 吋, 60 吋, etc.) Obtained, and in case the substrate G is, for example, a touch screen panel (TSP) for a smart phone, such as an i-pon using a direct layout window technology, the plurality of touch screen panels are made by the substrate G Cut to the desired size. Here, the plural panel and the plurality of touch screen panels for the television will generally be referred to as the panel P.

In the prior art described in detail above, since the substrate G is positioned on the suction platform 112 and then the substrate G is to be cut to a desired size, it is required to be entirely The following problem occurs by applying the coating liquid onto the substrate G by using the nozzle device 120 on the surface.

1. For example, in the case of LCD panels for mobile phones, mobile phone products of various sizes are based on various manufacturing companies (such as Samsung Electronics, Motorola, Nokia, etc.) and are based on a single manufacturing company (such as Samsung Electronics). Made. In order to manufacture LED panels of various sizes designed in large quantities, it is necessary to use expensive manufacturing equipment including different types of coating devices 100 depending on the size of the LED panels. Accordingly, the cost of overall manufacturing is significantly increased because different types of manufacturing equipment should be used depending on the size of various LCD panels.

2. Since in the prior art, the entire surface coating method is used on the substrate G, the coating liquid will be applied to the entire surface of the substrate G. After that, since only the plurality of panel P to be cut is used as the final product, an unused dead zone (DR) occurs on the substrate G, as can be seen from FIG. 1b. The substrate G is a high-priced component, and thus the manufacturing cost is greatly increased due to the occurrence of such dead zones (DR).

3. Again, the unwanted coating liquid applied to the dead zones (DR) will be removed by using separate cleaning processes and separate disposal processes. As such, these manufacturing costs and tact time are additionally increased due to the separate cleaning process and separate disposal processes used to remove the unwanted coating liquid 131 on the dead zones (DR).

4. Even when panels of various sizes are manufactured by using separate, high-priced manufacturing equipment as described in detail above, sales of such final products (such as high definition televisions or smart phones, etc.) are considered to be in the market/ When customer preferences or tastes are not smooth, it is not possible to apply separate, high-priced manufacturing equipment that has been installed to the manufacture of panels of different sizes. Therefore, from the viewpoint of productivity and commercial feasibility, the coating device 100 according to the prior art and the coating method using the coating device are not suitable for application to a wide variety of panels in a small number of various sizes. .

Therefore, new solutions for solving this prior art problem are required.
