Description

Technical Field

[0001] This utility model belongs to the field of LCD display module assembly technology, and in particular relates to an auxiliary device for improving the MTBF of LCD display modules. Background Technology

[0002] An LCD display module is a miniaturized, highly integrated hardware device that integrates an LCD screen, control circuits, and drive circuits. It is typically used in various devices that require information display, such as mobile phones, tablets, wearable devices, and some smart home products. During assembly, the LCD display module needs to be fully fitted to the structural components.

[0003] However, when existing LCD display modules are fully bonded to structural components, the LCD display modules are directly exposed on the back of the structural components without any protective structure. This makes the LCD display modules susceptible to corrosion from moisture, dust, static electricity, etc., resulting in malfunctions and directly reducing MTBF (Mean Time Between Failures). It also poses a significant safety hazard. Therefore, to solve the above problems, an auxiliary device for improving the MTBF of LCD display modules is proposed. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an auxiliary device for improving the MTBF (Mean Time Between Failures) of an LCD display module. This solves the problem that the lack of a protective structure for the LCD display module makes it susceptible to corrosion of the circuitry by moisture, dust, static electricity, etc., resulting in malfunctions, which directly reduces the MTBF and poses significant safety hazards.

[0005] This utility model is implemented as follows: an auxiliary device for improving the MTBF of a liquid crystal display module includes a structural component and a liquid crystal display module embedded in the top left side of the structural component. Multiple sets of mounting holes are evenly opened around the perimeter of the surface of the structural component. A sealing frame for enclosing the liquid crystal display module is fixed to the top left side of the structural component. A potting adhesive layer coated on the liquid crystal display module is provided inside the sealing frame.

[0006] As a preferred embodiment of this invention, a heat sink with its bottom attached to the potting compound layer is fixed inside the sealing frame.

[0007] As a preferred embodiment of this invention, the potting compound layer is made of a two-component flame-retardant and thermally conductive liquid potting compound.

[0008] As a preferred embodiment of this invention, the heat sink has multiple sets of heat dissipation holes evenly distributed on it, and multiple sets of heat dissipation pipes that communicate with the heat dissipation holes are evenly fixed on it.

[0009] As a preferred embodiment of this invention, the number of heat dissipation pipes is at least forty-five sets.

[0010] As a preferred embodiment of this invention, the top of the heat dissipation pipe and the top of the sealing frame are both on the same horizontal plane.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting a sealing frame, forms a barrier structure to shield the side of the LCD display module exposed on the back of the structural component. Combined with a potting compound layer, a two-component flame-retardant and thermally conductive liquid potting compound is directly injected into the sealing frame through a potting process, completely sealing the side of the LCD display module exposed on the back of the structural component. This effectively protects the LCD display module, preventing moisture, dust, and static electricity from corroding the LCD display module's circuitry, thus increasing the mean time between failures (MTBF). Furthermore, the two-component flame-retardant and thermally conductive liquid potting compound has excellent thermal conductivity, allowing it to conduct heat to the LCD display module while sealing it, improving the functionality of the device.

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown in the figure, the present invention provides an auxiliary device for improving the MTBF of a liquid crystal display module, including a structural component 1 and a liquid crystal display module 2 embedded on the top left side of the structural component 1. Multiple sets of mounting holes 8 are evenly distributed around the surface of the structural component 1. A sealing frame 3 is fixed to the top left side of the structural component 1 to enclose the liquid crystal display module 2. The sealing frame 3 is designed to form an enclosure structure to shield the side of the liquid crystal display module 2 exposed on the back of the structural component 1. A potting compound layer 4 coated on the liquid crystal display module 2 is provided inside the sealing frame 3. The potting compound layer 4 is designed to fully seal the side of the liquid crystal display module 2 exposed on the back of the structural component 1, effectively protecting the liquid crystal display module 2 and preventing moisture, dust, and static electricity from corroding the circuitry of the liquid crystal display module 2, thereby improving the mean time between failures (MTBF).

[0021] As a preferred embodiment of this utility model, a heat sink 5 with its bottom attached to the potting compound layer 4 is fixed inside the sealing frame 3. The heat sink 5 is designed to work with the potting compound layer 4 to improve the overall heat dissipation effect of the LCD display module 2 and avoid heat accumulation affecting the normal use of the LCD display module 2.

[0022] As a preferred embodiment of this invention, the potting compound layer 4 is made of a two-component flame-retardant and thermally conductive liquid potting compound. The two-component flame-retardant and thermally conductive liquid potting compound is directly injected into the sealing frame 3 through a potting process, which improves the overall sealing effect of the LCD display module 2. In addition, the two-component flame-retardant and thermally conductive liquid potting compound has excellent thermal conductivity, so that it can conduct heat to the LCD display module 2 while sealing it, thereby improving the functionality of the device.

[0023] As a preferred embodiment of this utility model, a plurality of heat dissipation holes 6 are evenly provided on the heat sink 5, and a plurality of heat dissipation pipes 7 that are connected to the heat dissipation holes 6 are evenly fixed on the heat sink 5. The design of the heat dissipation holes 6 and the heat dissipation pipes 7 increases the heat dissipation area of ​​the heat sink 5 so as to quickly absorb and diffuse the heat on the LCD display module 2 to the outside, thereby improving the heat dissipation speed of the LCD display module 2.

[0024] As a preferred embodiment of this invention, the number of heat dissipation pipes 7 is at least forty-five sets. Limiting the number of heat dissipation pipes 7 can further accelerate the heat dissipation speed of the LCD display module 2.

[0025] As a preferred embodiment of this invention, the top of the heat dissipation pipe 7 and the top of the sealing frame 3 are both on the same horizontal plane to avoid the heat dissipation pipe 7 being too long and affecting the normal assembly of the device.

[0026] The working principle of this utility model:

[0027] refer to Figures 1 to 3The sealing frame 3 forms a enclosure structure for the LCD display module 2, thus shielding one side of the LCD display module 2 exposed on the back of the structural component 1. Simultaneously, the user injects a two-component flame-retardant thermally conductive liquid potting compound directly into the sealing frame 3 using a potting process, forming a potting compound layer 4. This completely seals the side of the LCD display module 2 exposed on the back of the structural component 1, effectively protecting the LCD display module 2 from moisture, dust, and static electricity corrosion of its circuitry. The user then clips the heat sink 5 into the sealing frame 3, with its bottom contacting the potting compound layer 4, and fixes it as the layer cures. At this point, the heat sink 5 and heat pipe 7, combined with the excellent thermal conductivity of the two-component flame-retardant thermally conductive liquid potting compound, allow for rapid heat dissipation from the LCD display module 2.
