[0002] A liquid crystal display module is a display component that assembles liquid crystal display devices, connectors, integrated circuits, control and driving circuits, PCB circuit boards, backlights, and structural components together. It provides a standard interface for users to control the display output. Its core function is to integrate the glass substrate with the driving circuit and realize image presentation through the backlight. It is widely used in television, instrumentation and other fields. Some small liquid crystal display modules are highly integrated display components.

[0003] Currently, when LCD modules are in operation, especially some smaller LCD modules, the internal circulating heat dissipation structure has limited performance, and the heat dissipation components have insufficient heat dissipation performance, making it difficult to meet the heat dissipation requirements of the equipment and easily leading to overheating.

[0004] Therefore, to address the above problems, a liquid crystal display module with a circulating heat dissipation system featuring multi-layer heat dissipation components can be designed. Utility Model Content

[0009] Preferably, the VC heat sink covers the display driver chip area to reduce the temperature of local hot spots. A high thermal conductivity graphene film is attached to the back of the LCM to conduct heat laterally to the frame or middle frame area, fill the gap between the driver IC and the shielding cover, reduce contact thermal resistance, and fill the gap between the backlight module and the metal bracket to improve heat diffusion efficiency. Through the synergistic effect of the above multi-level heat dissipation structure, the small liquid crystal display module can maintain stable display performance under normal ambient temperature.

[0010] Preferably, a transparent protective cover is fixedly installed on the upper part of the housing, which is used to protect the display screen and other structures.

[0016] The beneficial effects of this utility model are:

[0017] 1. This circulating heat dissipation LCD module utilizes a heat spreader to achieve rapid and uniform heat diffusion, conveniently covering the core heat-generating area of ​​the motherboard and reducing the risk of hot spot accumulation. Combined with the high thermal conductivity of graphene material, it rapidly absorbs heat, forming a three-dimensional heat dissipation system to meet the high-performance requirements of the equipment. Thermal pads effectively reduce contact thermal resistance, achieving efficient heat transfer between the heat-generating components and the heat sink. The multi-layer composite structure design, including a thermally conductive gel layer, balances thermal conductivity and mechanical strength. Furthermore, the thermally conductive gel layer enables full-contact heat conduction, fully utilizing the working capacity of each component in the circulating heat dissipation assembly. With mutual support and combination, it significantly improves the heat dissipation performance of the equipment's heat dissipation components, effectively meeting the equipment's heat dissipation needs and optimizing the equipment's heat generation.

[0018] 2. This circulating heat dissipation LCD module uses a light-shielding frame and protective components to buffer and protect the internal components. It utilizes an elastic cavity and a buffer spring to absorb and convert external forces. In addition, the air damping formed in the cavity further reduces the buffer compression amplitude, controls the interference of external forces on the internal components, and avoids damage to the internal components when the LCD module is affected by external forces, which helps to extend the service life of the LCD module.

[0026] Please see Figures 1-5 This utility model provides an embodiment of a circulating heat dissipation liquid crystal display module, including a mounting shell 1. A circulating heat dissipation component is fixedly installed at the lower end of the mounting shell 1. A backlight plate 2 is fixedly installed on the upper side of the circulating heat dissipation component. A display screen 3 is fixedly installed at the upper end of the backlight plate 2. Heat dissipation grooves 4 are provided at both ends of the mounting shell 1. A light-shielding frame 5 is fixedly installed on the inner surface of the mounting shell 1. A protective component is provided inside the light-shielding frame 5. The circulating heat dissipation component includes a heat spreader 6. A thermally conductive pad 8 is fixedly installed at the upper end of the heat spreader 6. The protective component includes an elastic cavity 9. A connecting vent 10 and a buffer spring 11 are provided inside the elastic cavity 9. The heat spreader 6 realizes rapid diffusion and uniform distribution of heat. At the same time, the high thermal conductivity graphene film 14 accelerates the heat exchange efficiency. The thermally conductive pad 8 can effectively reduce the contact thermal resistance. With the thermally conductive gel layer 15, a multi-layer composite structure design is realized while ensuring full contact heat conduction. This fully utilizes the working capacity of each component in the circulating heat dissipation component, improves the heat dissipation performance of the equipment's heat dissipation components, and conveniently meets the heat dissipation requirements of the equipment.

[0027] Please see Figures 1-3In this embodiment, a transparent protective cover 12 is fixedly installed on the upper end of the housing 1. The transparent protective cover 12 is used to protect the display screen 3 and other structures. A dustproof net 13 is fixedly installed on the inner side of the heat dissipation groove 4. The dustproof net 13 is used to block dust and impurities from entering the equipment. The heat dissipation plate 6 is used to reduce the temperature of local hot spots. A high thermal conductivity graphene film 14 is provided at the lower end of the heat dissipation plate 6 to conduct heat laterally to the frame or middle frame area. A thermal conductive gel layer 15 is provided at the upper end of the thermal conductive pad 8. The thermal conductive pad 8 is used to reduce contact thermal resistance. The thermal conductive gel layer 15 is used to fill gaps. The heat dissipation plate 6 can achieve rapid diffusion and uniform distribution of heat. The properties of the high thermal conductivity graphene film 14 itself can accelerate the heat exchange efficiency. The thermal conductive pad 8 can effectively reduce contact thermal resistance and, together with the thermal conductive gel layer 15, achieve a multi-layer composite structure design to balance thermal conductivity and mechanical strength. The heat dissipation groove 4, together with the circulating heat dissipation component, can complete the efficient heat dissipation work.

[0028] Please see Figures 4-5 In this embodiment, a connecting groove 16 is provided at the lower end of the light-shielding frame 5. The connecting groove 16 and the protective components are distributed at equal intervals. The connecting air hole 10 is connected to the connecting groove 16. Connecting blocks 17 are fixedly installed at both ends of the buffer spring 11. The connecting blocks 17 are fixedly connected to the light-shielding frame 5.

The elastic cavity 9 can be compressed and deformed. The elastic deformation capability of the buffer spring 11 itself can absorb and convert external forces. During this process, the elastic cavity 9, together with the connecting air hole 10 and the connecting groove 16, can achieve a certain air pressure change (which can form a certain air damping) and realize the buffering function of the protective components.

[0029] During operation, the various structural layers of the circulating heat dissipation assembly work together to dissipate heat. The heat spreader 6 enables rapid diffusion and uniform distribution of heat. At the same time, the high thermal conductivity graphene film 14 further accelerates the heat exchange efficiency due to its own material properties. The thermally conductive pad 8 can effectively reduce contact thermal resistance. The thermally conductive gel layer 15, together with the heat dissipation groove 4, achieves a multi-layer composite structure design while ensuring full contact heat conduction, balancing thermal conductivity and mechanical strength. The heat dissipation groove 4 works with the circulating heat dissipation assembly to complete efficient heat dissipation. The light-shielding frame 5 and the protective assembly protect the internal components. When under pressure, the elastic cavity 9 is compressed and deformed. The elastic deformation capability of the buffer spring 11 absorbs and converts the external force. At the same time, during the compression deformation of the buffer spring 11, the elastic cavity 9 and the vented groove structure can achieve a certain air pressure change, realizing the buffer function of the protective assembly and further completing the safety protection function of the internal components of the equipment.

[0030] Through the above steps, the heat spreader 6 achieves rapid diffusion and uniform distribution of heat. At the same time, the high thermal conductivity graphene film 14 accelerates the heat exchange efficiency. The thermally conductive pad 8 effectively reduces contact thermal resistance. The thermally conductive gel layer 15 ensures full contact heat conduction while realizing a multi-layer composite structure design. This fully utilizes the working capacity of each component in the circulating heat dissipation assembly, improves the heat dissipation performance of the equipment's heat dissipation components, and facilitates meeting the heat dissipation needs of the equipment. This solves the problem that the heat dissipation performance of the heat dissipation components is insufficient when the LCD display module is working, making it difficult to meet the heat dissipation needs of the equipment and easily causing overheating.
