Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to an adhesive tape for OLED display components. Background Technology

[0002] OLED, also known as Organic Electron Laser Display or Organic Light Emitting Semiconductor, is a current-driven organic light-emitting device. It emits light through the injection and recombination of charge carriers, with the luminous intensity directly proportional to the injected current. Under the influence of an electric field, holes generated at the anode and electrons at the cathode move and are injected into the hole transport layer and electron transport layer, respectively, migrating to the emissive layer. When these two electrons meet in the emissive layer, they generate excitons, which excite the light-emitting molecules to ultimately produce visible light.

[0003] Currently, OLED displays use single-sided aluminum foil tape to shield and protect components that are prone to electromagnetic leakage and interference during the manufacturing process. However, this approach presents the following problems in actual operation:

[0004] 1. Although the aluminum foil layer attached by single-sided aluminum foil tape can provide electromagnetic shielding for electronic components, the aluminum foil layer is relatively thin and is easily damaged when cut or torn, resulting in gaps in the shielding layer and a decrease in shielding effectiveness.

[0005] 2. Because the aluminum film is cut, the original oxide layer is cut off, making the cut surface of the aluminum film prone to rusting. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide an adhesive tape for OLED display components, so as to solve the technical problems of the current single-sided aluminum foil tape used for electromagnetic shielding of OLED display components, which is prone to tearing of the aluminum film during application and cutting, and the aluminum film cut surface is prone to rust. At the same time, the adhesive component of the tape will age and lose its stickiness after long-term use, and is prone to falling off.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] An adhesive tape for an OLED display assembly includes a tape fixing block, wherein an antimagnetic tape is fixedly mounted on the outer surface of the tape fixing block, and the antimagnetic tape includes an aluminum film protective component.

[0010] The aluminum film protection assembly includes an outer protective frame, on the inner surface of which hot melt resin is fixedly installed, on the inner wall of which a connecting rod is fixedly installed, on the bottom of which a connecting plate is fixedly installed, and on the bottom of which an aluminum film is fixedly installed.

[0011] As an improved technical solution, a connecting groove is provided on the top of the aluminum film, the inner surface of the connecting groove is fixedly connected to the outer surface of the connecting plate by adhesive, and the outer surface of the connecting rod is fixedly connected to the inner surface of the hot melt resin.

[0012] As an improved technical solution, a fixing adhesive layer is fixedly installed on the bottom of the aluminum film.

[0013] As an improved technical solution, the thickness of the hot melt resin is 0.2 mm.

[0014] As an improved technical solution, the thickness of the aluminum film is 0.05 mm.

[0015] As an improved technical solution, the material of the fixing adhesive layer is silicone adhesive.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model improves the OLED display assembly by adding a design to repair and prevent rust on the gaps in the aluminum film inside the adhesive tape. Through the cooperation of the outer protective frame, hot melt resin, connecting rod, and connecting plate, and the cooperation of the connecting plate with the aluminum film and connecting groove, the cut surface created when the tape is cut is sealed by heating the tape at high temperature. The hot melt resin softens the tape and covers the cut surface of the tape, thus preventing the aluminum film from rusting after the tape is cut, which would affect the tape's antimagnetic effect. At the same time, the aluminum particles in the hot melt resin will cover the gaps created when the aluminum film is folded.

[0018] 2. This utility model improves the adhesion time of adhesive tape by increasing the design of the adhesive tape and by using the combination of the fixed adhesive layer and the aluminum film to replace the original glue with rubber glue. This improves the adhesion time of adhesive tape used for electronic components in OLED displays and avoids the problem of the adhesive component of the tape aging and losing its stickiness after long-term use, causing the tape to fall off the components.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this embodiment provides an adhesive tape for OLED display components. The adhesive tape for OLED display components includes an adhesive tape fixing block 1. An antimagnetic tape 2 is fixedly installed on the outer surface of the adhesive tape fixing block 1. The antimagnetic tape 2 includes an aluminum film protection component 21.

[0030] The aluminum film protection component 21 includes an outer protective frame 211, a hot melt resin 212 fixedly installed on the inner surface of the outer protective frame 211, a connecting rod 213 fixedly installed on the inner wall of the outer protective frame 211, a connecting plate 214 fixedly installed at the bottom of the connecting rod 213, and an aluminum film 215 fixedly installed at the bottom of the outer protective frame 211.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the aluminum film 215 is provided with a connecting groove 216, the inner surface of the connecting groove 216 is fixedly connected to the outer surface of the connecting plate 214 by adhesive, and the outer surface of the connecting rod 213 is fixedly connected to the inner surface of the hot melt resin 212.

[0032] The outer protective frame 211 is made of flexible plastic, and its connecting rod 213 and connecting plate 214 are used to connect the aluminum film 215 to avoid the effect of squeezing and shifting the outer protective frame 211 when the hot melt resin 212 is squeezed.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing adhesive layer 22 is fixedly installed on the bottom of the aluminum film 215.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the thickness of hot melt resin 212 is 0.2 mm.

[0035] Unsaturated polyester resin is one of the most commonly used thermosetting resins. It is generally a linear polymer compound with ester bonds and unsaturated double bonds, formed by the condensation polymerization of unsaturated diacids and diols or saturated diacids and unsaturated diols. Typically, the polyesterification condensation reaction is carried out at 190–220°C until the desired acid value (or viscosity) is reached. After the polyesterification condensation reaction is completed, a certain amount of vinyl monomer is added while the mixture is still hot to form a viscous liquid. This polymer solution is called unsaturated polyester resin.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the thickness of the aluminum film 215 is 0.05 mm.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the material of the fixing adhesive layer 22 is silicone adhesive.

[0038] Silicone adhesive is a type of silicone rubber used for bonding items. It cures by contacting water molecules on the surface of the object being bonded or sealed, or by water molecules in the air. Silicone adhesive has strong adhesion and good bonding effect on materials such as silicone, plastic, and metal.

[0039] In use, the user cuts the antimagnetic tape 2 to a suitable length and attaches it to the internal components of the OLED display to cover the components. Then, the user heats the antimagnetic tape 2 with a hot air gun to soften the hot melt resin 212. The user then uses a tool to squeeze the outer protective frame 211 to squeeze out the internal hot melt resin 212 and cover the cut area of ​​the aluminum film 215. At the same time, the aluminum powder in the hot melt resin 212 fills the gaps in the torn aluminum film 215, ensuring that the antimagnetic effect of the aluminum film 215 is still maintained. Since silicone glue is used as the fixing adhesive layer 22, the tape can be fixed inside the OLED display for a long time.

[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
