[Prior Art] Referring to Figs. 1 to 3, a schematic diagram of a manufacturing process of a circuit cover plate in a conventional flat title "Yada" shoulder shoulder is shown. First, referring to Fig. 1, a material 10 is made of metal. Next, the test chart? # ≫ Hum Figure 2, the material 10 is formed into the shape of the circuit cover plate 12 by stamping. Since the circuit cover plate 12 is opposite to the inverter or the inverter, Other circuit components (such as chips, resistors, valleys, etc.) (not shown in the figure) are prone to short circuits due to static electricity, discharge, or improper contact. Therefore, the areas where short circuits may occur A pre-defined area 121 is planned. Then, as shown in FIG. 3, a protective sheet (such as an insulating sheet or a security sheet) 14 is attached to the pre-defined area 121 to prevent the circuit components from being covered by the circuit. Possible contact short circuit occurred on the board 12. In the conventional manufacturing process, the protective sheet 14 is affixed to a double-sided tape, and then the protective sheet 14 with the double-sided tape is cut to an appropriate length, and then manually. Protect this with double-sided tape Sheets 14 are attached to the pre-defined area 121 on the circuit cover 12. The disadvantage of this conventional process is that the attachment process of the protective sheet 14 is done manually. Therefore, the processing time is too long and the production efficiency cannot be achieved. Upgrade, so this processing process brings extremely serious bottles to the current production line

In addition, since the protective sheet 14 with double-sided adhesive is manually attached to the cover board 12 of the mysterious circuit in this process, a chance of this error (such as incorrect or wrong position of the paste) is greater (especially large) Size of the circuit cover), even if the error may not cause serious product defects, but it will cause prolonged processing time when it is reattached. Furthermore, the protective sheet 14 is adhered to the 7 circuit cover 12 through double-sided tape. The adhesive force is not strong enough to be easily detached, so that the effective protection area is reduced. It is even impossible to avoid the occurrence of a short circuit. Therefore, it is necessary to provide an innovative and progressive structural element for a flat display and a manufacturing method thereof to solve the above problems. [Summary of the invention] The main purpose of the present invention is to provide a manufacturing process of the structural elements of a flat panel display by using a protective layer firstly coated on the material, and then forming the material into a frame, because it can use mechanical equipment Production can not only save manpower and increase production support, but also the protective layer can be accurately coated on the required position through mechanical control. Another object of the present invention is to provide a structural element for a flat display, which is characterized in that a specific area on the surface of the structural element is directly coated with a protective layer, so that the protective layer has an adhesive force that is higher than that of a double-sided insulating sheet. Adhesives are much stronger. [Embodiment] Referring to FIG. 4 to FIG. 6, a process schematic diagram of a structural element of a flat display of the present invention is shown.

The coating step may be a conventional step such as painting, printing, roll coating or transfer printing. The following two methods of coating are listed. The first method is to use a screen as a coating fixture. The opening area is relative to the pre-defined area 201, and a defense is placed on the screen. Then use a scraper to evenly coat the protective layer material on the protective material screen. The second method is to cover the area that is not to be coated with a fixture to expose the area to be coated (that is, the predefined area 201), and then apply a protective layer material by spraying or smearing. On this predefined area 201. Then, the child-resistant layer 24 is cured or hardened. The curing method may be a conventional method such as drying or drying, such as putting it in an oven or heating and conveying it, or it may be irradiated with a light source of UV light to make the protection. The layer 24 is cured. Finally, referring to FIG. 6, the material 20 is formed into a structural element 22. The forming process may be stamping or other conventional forming methods. The structural element 22 of the doll may be a circuit cover plate and an aluminum back of the liquid crystal display. Plate or iron front frame. In the present invention, the production line of the forming process is the same as that of the "known" production line, that is, the present invention can be applied without modifying the original production line. In one embodiment of the present invention, the material 20 is coated with the protective layer 24 and then formed into a structural element 22. However, it can be understood that the material 20 can also be formed into a structural element 22 and then processed. This protective layer 24 is applied.

Its protective effect. In addition, the protective layer 24 is directly coated on the structural element 22, and it is not necessary to use a conventional double-sided adhesive or other adhesive between the protective layer 24 and the structural element 22. Therefore, its adhesion is higher than that of conventional The adhesion of the double-sided adhesive tape of the insulation sheet is much larger, and it is not easy to fall off. The accuracy of the position of the protective layer is also improved at the same time. The manufacturing method of the present invention is described in detail below with a preferred embodiment. First, a steel plate material is provided, and a pre-defined meaning area is planned on the steel plate material. Next, the steel plate material is placed on a screen printing machine, and the opening area on the screen on the screen printing machine is relative to the pre-defined area. Next, an ink is provided as an insulating layer. The ink is a series 3000 urea formaldehyde resin / epoxy resin (Epoxy Resin / Urea Formaldehyde Resin Ink) produced by Seiko. Its composition is about 30% epoxy resin. (Epoxy Resin), 20% Urea Formaldehyde Resin and other hardeners. The ink was then placed on the screen, and then the ink was spread evenly with a doctor blade. Next, after removing the steel plate material from the screen printing machine, it is placed on a heat-transmittable material and dried at 120 to 200 C for 2 to 8 minutes to form an insulating layer on the steel plate material. The insulation layer can be tested afterwards, which includes subsequent strength test, high voltage test, and hardness test. The subsequent strength test is to use 600 series tape produced by 3M company and stick it apart. The test result is acceptable. At 500 volts, the test result is acceptable. The hardness test result is the pencil hardness F. Finally, the steel plate material is made into an iron front frame by the existing stamping process of O: \ 92 \ 92466.DOC -9- 200537172.
