Abstract

The present invention provides a coating method for directly connecting the anti-static layer of information display panel to grounding conductive devices. The method first coats conductive material on the in effective edge of the display panel of the information display device, so that the coated range is extended from the ineffective edge to an anti-explosion belt arranged on a side of the information display device. Then, an anti-static coating is coated on the display panel, so that the anti-static coating is exactly coupled to the conductive material. Next, an anti-reflection coating is coated on the anti-static coating. Accordingly, after completing the coating process, the anti-static coating and the anti-explosion belt can form a route directly via the conductive material, thereby surely guiding the static voltage accumulated on the display panel to a grounding terminal, so as to completely remove the negative influence on the video display caused by the static voltage.

Description of the invention (1) Field of the invention: The present invention relates to an information display panel which can make its antistatic coating layer directly removable, especially a coating method. The previous technology of directly connecting with the grounding conductive element: According to the cathode ray tube of a general video display (the light intensity is about 4% ~ 8% of the incident light, it is extremely easy for users who use the surface to reverse it. Causes fatigue; the resolution and color contrast that should be displayed on the display. In addition, 纟 ς: low resolution and high resolution and high daylight quality display (/ increasingly driving voltage-generally up to 25KV, very easy to frequency interference, because The two ^ ^ formation of a static thunder house on the surface of the non-destructive state, causing the dust particles in the atmosphere to adsorb on its surface, breaking the daylight, and when using this type of display in low humidity areas, it is also suitable for users Electric shock. Therefore, in order to solve the quality requirements related to ± n 7 β, generally, the display panel of the cathode ray tube will be anti-glare (Antil-Giare), anti-reflective (Anti-Reflection) and Anti-static (Antl-Static) and other surface textures, by applying multiple anti-static and anti-reflection coatings to effectively reduce the adverse effects of light source reflection on the video image, and greatly accumulate the static voltage on it _ At a glance Generally conventional color cathode ray tube of a square, as shown in FIG see Section J, mainly comprising of a sealed glass tube (sealed glass enVel〇pe) 12, the tubular body 12 is provided with a display panel (Faceplate)

Including a plurality of fluorescent units capable of emitting fluorescent light respectively, a plurality of linearly arranged electron grabs 20 are provided in the neck portion 18 of the sealed glass tube body 12 to generate a three-color electron beam 22 The electron beams 22 are controlled by a magnetic deflection vehicle (magnetic de f 1 ec ti on y oke), can be deflected in the horizontal and vertical directions, and are focused on the fluorescent layer 24. When the color When the two-color electron beam 22 'generated by the cathode ray tube 10 is focused on each of the fluorescent units on the inner wall surface of the display panel 14, the units emit colored light to display video on the display panel 14. image. On such a conventional color cathode ray tube 10, as shown in FIG. 2, an inner wall surface of the display panel 14 is coated with a fluorescent layer 142, and an outer wall surface is coated with a coating layer 1 4 4. The coating layer 1 4 4 includes an inner antistatic coating layer 146 and an outer antireflective (and / or antiglare) coating layer 1 48. The antistatic coating layer 1 4 6 is connected with a conductive aluminum foil 5 in parallel. The anti-static coating layer 146 is connected to the ground through the conductive foil 50 to remove the electrostatic charge accumulated on the surface of the outer wall of the display panel 14 with the effect X; the anti-reflection (and / or anti-glare) coating The cloth layer 48 is used to reduce the reflection or random emission of the external surface of the display panel 4 to the external ambient light, so that the display panel 4 can display a clearer video image. = Front ^ After the manufacturer of the video display has completed anti-static and anti-reflection (and / or anti-glare) coatings on the outer wall surface of the display panel 14, please refer to Figures 2 and 3 again. 6〇The conductive aluminum foil 5〇

In general, the methods used by manufacturers of video displays today to remove the static charge accumulated on the outer wall surface of the display panel 14 can be roughly divided into the following two types according to their coating: = (1) The wet coating method is to apply anti-electric and anti-reflection coating to the display surface of the cathode ray tube using spray or spin coating Upj 'coa ti ng} and other methods. In other coating methods, the coating material is coated on the display panel 14 in the form of molecular stacking. The intermolecular bond distance is large, resulting in the formation of the antistatic coating layer and the antireflection coating layer I. Diffusion will occur, as shown in Figure 4. The conductive molecules 51 in the two electrostatic coating layers diffuse into the anti-reflective coating layer and the surface, so the anti-static / anti-reflective coating process is completed. After that, its coating layer,

Evening has a conductive property of 104 ~ 106 ω / -2, so the conductive aluminum flute 50 can be connected to the outer surface of the coating layer 52 by using a glue: :: HAI, the electric name box 50 and the explosion-proof belt 70 The connection is to have the electrostatic charge accumulated on the J == surface, however, the cost of using this method = 50% aluminum is more expensive. Toad (2) dry coating method: Sputter coating (sputter = method is used to evaluate the anti-reflection coating on the display panel 14 of the cathode ray tube 10, respectively. Form, is coated on the display panel 14, and its cloth and arrangement: Compared with 522432 V. Description of the invention (4), it can be clearly distinguished from the antistatic coating layer 46 and the antireflection coating layer 1 4 8. As shown in Figure 5, in general, the antistatic coating layer 4 6 is a thin film with conductive properties (such as ITO, Ti〇2, Ti, TiN and other materials), the anti-reflective coating The layer 1 4 8 is a silicon dioxide film. Since the stone dioxide film 1 8 is coated on the conductive film 1 4 6 and is an insulating film, it leads to the Wenxihai stone oxide film 1 The insulating surface of 48 cannot connect the conductive aluminum foil 50 to the conductive film 146, so in these dry coating methods, in order to make the conductive aluminum foil 50 can be smoothly connected to the antistatic coating On layer 4.6, a display panel manufacturer, ASAfn gLASS C0MPANY, has completed antistatic and antireflection coating on the display panel. After the processing, the ultrasonic spot welding method (sunbonder) is used, as shown in FIG. 6, at the position of the two side edges of the display panel, the anti-reflection coating layer of the silicon dioxide is damaged and formed at this position. A conductor 55 is used to connect the conductive aluminum foil 50 to the conductor 55 through the adhesive tape 60. The antistatic coating layer 146 can sequentially pass through the conductor 55 and the conductive aluminum pig 50, and is connected to the explosion-proof tape 70. Connected to remove the static charge accumulated on the "outer wall surface of the display panel." Xiling: In the aforementioned wet coating process, each of the antistatic and anti-reflection = spraying amount and physical production, it is difficult to control Therefore, its anti-reflection port ", H > is not stable and cannot effectively improve the video of the video display. The coating material is likely to cause problems such as recycling difficulties and environmental pollution. In the dry coating process, etc. Because of its conductive inscription. The process of connecting the electrical coating layer 146 and the explosion-proof belt 70 is also not ideal. Spear, shell 522432 V.
