[0023] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0024] Please refer to Figures 1-5, a shipborne reinforced liquid crystal display provided by the utility model, includes a liquid crystal module 1, an electrical control module 2 and a partition cover 3. The partition cover 3 is arranged between the liquid crystal module 1 and the electrical control module 2. Shielding treatment is carried out between the liquid crystal module 1 and the electrical control module 2 through the partition cover 3, and it also has effective buffering at the same time. The liquid crystal module 1 includes a front panel 11, a liquid crystal screen 12, an AG glass 13 and a pair of corner pieces 16. The AG glass 13 is encapsulated on the surface of the liquid crystal screen 12 to protect the liquid crystal screen 12 from scratches. The liquid crystal screen 12 and the AG glass 13 are fixed on the front panel 11 through the two corner pieces 16. Glue is used for fixing between the periphery of the AG glass 13 and the front panel 11, and copper foil is used for edging to achieve good EMC effect. The partition cover 3 is fixed to the front panel 11 with screws. The liquid crystal screen 12 selects the liquid crystal screen of BOE with the model GV215FHM-N10. It adopts high-quality materials and special production processes, can work stably in harsh environments and is not easily damaged.

[0025] Specifically, the electrical control module 2 includes a connector box 21, a rear cover plate 22, an image main board 23, a power supply board 24 and a filter 28. The connector box 21 is fixed on the surface of the partition cover 3. The connector box 21 and the rear cover plate 22 are fixed with screws. The image main board 23, the power supply board 24 and the filter 28 are installed in the installation cavity formed between the connector box 21 and the rear cover plate 22, and are covered by the rear cover plate 22 for installation to achieve good EMC effect and maintenance performance. At the same time, wiring is carried out in this installation cavity, with reasonable layout and appropriate wiring. On the side of the connector box 21, there are also arranged a power connector 25, a fuse 26, a three-point separate grounding post 27 and a DVI three-way signal connector board 29.

[0026] The power supply board 24 converts the input voltage AC220V into DC12V and outputs it to supply power to the internal image main board 23. The power supply has a wide range of input, supports AC220V ± 20%, and meets the input range required by the technical requirements.

[0027] The image main board 23 converts the DVI signal into an LVDS signal, and after converting the signal into an LVDS signal through a transmitter, it drives the liquid crystal screen 12 to display. At the same time, a heat conduction plate is pasted between the image main board 23 and the partition cover 3, which is used to transfer the heat generated by the operation of the image main board 23 to the partition cover 3 for large-area heat dissipation, ensuring the effective heat dissipation ability of the image main board 23 and preventing the chip from being damaged due to overheating caused by the high temperature of the image main board 23.

[0028] Specifically, a heat dissipation strip 14 is also connected to the side of the liquid crystal screen 12. The heat dissipation strip 14 is respectively in contact with the front panel 11 and the partition cover 3. The heat dissipation strip 14 is in contact with the liquid crystal screen 12, and can transfer the heat generated by the operation of the liquid crystal screen 12 to the front panel 11 and the partition cover 3, realizing heat conduction and dissipation of the liquid crystal screen 12, improving the thermal stability performance of the display. The corner fitting 16 and the liquid crystal screen 12 are isolated and overlapped through an insulating filling part 15, forming a three - place separation effect.

[0029] Specifically, a backlight board 201 and a wire routing rack 202 are also installed in the installation cavity formed between the aviation plug box 21 and the rear cover plate 22. The wire routing rack 202 is used to mechanically fix the wire routing in the installation cavity. The image main board 23 outputs power and backlight control signals to the backlight board 201, and the control of the backlight is realized by the operation of the aviation plug box 21.

[0030] Specifically, the power board 24 uses a power module of the Golden Sun model LOF120 - 20B12. The input voltage range of this power module is AC 85V - AC 305V, the isolation voltage is AC 4000V, and it has short - circuit, over - current, over - voltage, and over - temperature protection. The efficiency is as high as 95%. The operating temperature range is - 40°C to + 85°C. A power supply box is also arranged in the installation cavity formed between the aviation plug box 21 and the rear cover plate 22. The power module is installed in the power supply box and is treated with potting glue. Through the potting glue treatment, it can effectively isolate the erosion of the external environment on the internal circuit of the power module, and improve the moisture - proof, dust - proof, and shock - resistant performance of the internal circuit of the power module.

[0031] At the same time, the potting glue treatment also has good electrical insulation and thermal conductivity, which can ensure that the power board 24 maintains stable electrical performance and heat dissipation effect during operation, achieving multiple benefits with one action.

[0032] In addition, it should be noted that each component and module in the electrical control module 2 of this application adopts existing technologies, and the specific shape, structure, and working principle will not be elaborated here.

[0033] Specifically, the front panel 11 and the partition cover 3, as well as the aviation plug box 21 and the rear cover plate 22, are in close surface - to - surface contact through conductive lines, forming a good shielding effect between the front panel 11 and the partition cover 3, and between the aviation plug box 21 and the rear cover plate 22. Handles 111 are respectively fixedly installed on both sides of the surface of the front panel 11. By holding the handles 111, it is convenient to install and maintain the display.

[0034] In summary, this ship - borne reinforced liquid crystal display is reinforced with excellent components, and has professional designs such as enhanced heat dissipation, vibration reduction, shock resistance, and electromagnetic compatibility. It has high reliability and stability, excellent performance, simple operation, meets relevant usage requirements, and has a long service life in various harsh environments.
