Abstract
Description
Technical Field
[0001] The invention relates to the technical field of AMOLED module antifouling films, and in particular to a preparation process of an AMOLED module high-efficiency antifouling film. Background Art
[0002] AMOLED products have a wide range of applications in the display market, such as smart bracelets and smart watches. With the advancement of technology, more and more watches and bracelets are becoming increasingly popular. Therefore, during normal use, the oil on the fingers will cause a lot of dirt on the surface of AMOLED smart watches, which will affect the customer experience. The previous treatment method was to plate AF on the cover of the AMOLED module, but the experience of this solution is not so good. Sometimes customers will also report the problem of surface oil after plating. This is because AF relies on surface diffuse reflection to achieve no oil on the surface. According to the actual situation, fingerprints will be less obvious after AF plating than without AF plating, and the more times the plating is applied, the less obvious the fingerprints will be. This also reflects that as customers use the product, fingerprints will become more and more obvious and difficult to control. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a process for preparing an efficient antifouling film for an AMOLED module.
[0004] The objective of the present invention is achieved through the following technical solutions:
[0005] A process for preparing an efficient antifouling film for an AMOLED module specifically comprises the following steps: S1, preparing raw materials: preparing a silicon compound, a carbon element and a silane group compound in a ratio of 9.5:0.3:0.2;
[0006] S2. Mixing raw materials: mix silicon compounds, carbon elements and silane group compounds according to the proportion and pour them into the mixer; S3. Prepare the vacuum chamber: put the substrate into the vacuum chamber; S4. Evacuate: evacuate the vacuum chamber with the substrate; S5. Ion bombardment: introduce the mixed raw materials directly into the ion bombarder, and inject the atomic vapor flow into the surface of the substrate; S6. Preheating: preheat the substrate sprayed with the mixed raw materials; S7. Baking: put the preheated substrate into the baking chamber for baking; S8. Take out: take out the baked substrate and cool it; S9. Post-plating treatment: perform post-plating treatment on the surface of the substrate after the coating is completed.
[0007] In one embodiment, before step S1, a blue film needs to be screen-printed on the surface of the substrate, and then the substrate is cut, and the substrate after cutting is processed by CNC machining.
[0008] In one embodiment, before step S1, the rear substrate that has been processed by CNC machining needs to be polished, stripped and tempered, and white glass QC is performed, and silk screen printing is performed on the surface to complete step S1.
[0009] In one embodiment, the discharge port of the raw material mixing device and the feed port of the ion bombardment device used in step S2, step S3, step S4 and step S5 are interconnected, and the discharge port of the ion bombardment device is located in the vacuum chamber.
[0010] In one of the embodiments, in steps S3 and S4, a vacuum pump is connected through the vacuum chamber, and the gas pressure inside the vacuum chamber reaches below 10-2Pa when evacuating the chamber.
[0011] In one of the embodiments, in step S5, when the vacuum chamber becomes a vacuum environment, the plating material to be bombarded by ions is heated, causing its atoms or molecules to vaporize and escape from the surface to form a vapor flow, which is incident on the surface of the substrate and condensed to form a solid film.
[0012] In one embodiment, in step S7, the temperature in the baking chamber is generally maintained between 50° and 60°, and the baking time is between 1 and 2 hours.
[0013] In one of the embodiments, in step S8, when taking out the substrate from the baking chamber, it is necessary to wait for the temperature in the substrate chamber to cool down first, so that the plating vapor flow forms a solid film on the surface of the substrate and can be cooled and fixed.
[0014] In one embodiment, in step S9, the solid film formed on the surface of the substrate needs to be polished to make the surface smooth and flat.
[0015] In one embodiment, after step S9, the finished product after post-plating treatment is inspected, and those that pass the inspection are sent to the finished product transport rack.
[0016] Compared with the prior art, the present invention has at least the following advantages:
[0017] The present invention discloses a highly efficient antifouling film preparation process for an AMOLED module. Silicon compounds, carbon elements and silane group compounds are mixed in a ratio of 9.5:0.3:0.2, and sprayed on the glass cover of the AMOLED module through a coating evaporation process. The antifouling film does not contain fluorine or oil, but is actually oleophilic, so it has a very low oil contact angle. By using a completely different mechanism, the coating allows light to easily pass through fingerprint stains without refraction, so that fingerprints can be easily hidden. In addition, since the material is hydrophobic and easy to clean, its performance matches that of existing anti-fingerprint solutions, so that it will not be contaminated by fingerprints even if it is used for a long time and multiple times.
