Description

Technical Field

[0001] The utility model relates to the technical field of displays, and in particular to an OLED module. Background Art

[0002] like Figure 1 As shown in the figure, the main components of the current OLED display module are: OLED panel 01, heat sink 02, external backplane 03 (can also be used as an exterior component). The OLED panel itself is not strong enough, so it needs to be reinforced by a heat sink and an external backplane. These components are connected by double-sided foam. In order to protect the OLED panel and prevent damage and fragmentation, the OLED panel needs to be embedded in the external backplane. As a result, under this architecture, the current architecture is difficult to repair. When cutting the foam, it is very easy to cause the OLED panel to break. The price of the OLED panel is close to 80% of the cost, so solving the maintainability of the OLED display module has become an urgent problem. Summary of the invention

[0003] The purpose of the utility model is to provide an OLED module to solve the maintenance problem of the OLED display module, reduce the breakage during the maintenance of the OLED panel, and also reduce the amount of foam used and the labor cost, and improve reliability.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An OLED module comprises an OLED panel, a heat sink and an external backplane, wherein the OLED panel is arranged at the front end of the external backplane, and the heat sink is arranged inside the external backplane; the upper side of the heat sink is connected to the upper side of the external backplane via a snap-fit ​​structure; at least one location in the middle of the heat sink is connected to the external backplane via an easy-pull adhesive, and the easy-pull adhesives at corresponding locations on the external backplane are respectively provided with operation holes for removing the easy-pull adhesives; screws are also connected between the external backplane and the heat sink.

[0006] Furthermore, the heat sink and the OLED panel are bonded and fixed by double-sided foam.

[0007] Furthermore, the easy-to-pull adhesive is connected to the adhesive boss of the heat sink.

[0008] Furthermore, the screw passes through the back of the external back plate and is threadedly connected to the connecting boss on the heat sink.

[0009] The utility model adopts the above technical solution, which can easily separate the heat sink from the external back plate. Therefore, the assembly of the OLED panel and the heat sink is free from the internal structural restrictions, and the OLED panel can be easily separated without damaging it.

[0017] Figure 7 for Figure 3 Cross-sectional view of DD in. DETAILED DESCRIPTION

[0018] like Figure 2-7 As shown, the utility model is an OLED module, comprising an OLED panel 1, a heat sink 2 and an external backplane 3. The OLED panel 1 is placed at the front end of the external backplane 3, the heat sink 2 is placed inside the external backplane 3, and the heat sink 2 is also fixed to the back of the OLED panel 1 by bonding with a traditional double-sided foam 4.

[0019] The connection method between the heat sink 2 and the external back plate 3 is as follows:

[0020] The upper side of the heat sink 2 is connected to the upper side of the external back plate 3 via a snap-fit ​​structure 5 to facilitate disassembly;

[0021] At least one part of the middle of the heat sink 2 is connected to the external back plate 3 through an easy-pull adhesive 6, and the easy-pull adhesive 6 is connected to the adhesive boss 21 of the heat sink 2, and the easy-pull adhesive 6 at each part of the external back plate 3 is respectively provided with an operation hole 7 for removing the easy-pull adhesive 6, so that the easy-pull adhesive 6 can be removed through the operation hole 7 when needed;

[0022] To further ensure the connection strength, a screw 8 is further connected between the external back plate 3 and the heat sink 2. The screw 8 passes through the back of the external back plate 3 and is threadedly connected to the connection boss 22 on the heat sink 2.

[0023] The heat sink 2 can be easily separated from the external back plate 3 under the structure of the present invention. Thus, the assembly of the OLED panel 1 and the heat sink 2 is free from the internal structural restrictions, and the OLED panel 1 can be easily separated without damaging it.

[0024] Because the OLED panel emits a lot of heat when in use, the double-sided foam has high requirements and heat-resistant double-sided adhesive must be used. In the architecture of the utility model, a structural connection is used between the heat sink and the external back panel instead of double-sided foam, which not only helps to improve reliability and maintainability, but also reduces the amount and cost of double-sided foam.

[0025] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
