Description

Technical Field

[0001] The present invention belongs to the technical field of liquid crystal modules, and in particular relates to a universal liquid crystal module. Background Art

[0002] A universal LCD module is a liquid crystal display component with a standardized interface and compatibility design. It is suitable for industrial control, consumer electronics, medical equipment and other fields. Its core is composed of a liquid crystal panel assembly, a drive circuit module and a backlight assembly. The liquid crystal panel assembly controls the light transmittance through molecular arrangement to achieve image display. The drive circuit module receives and processes signals and adjusts parameters such as brightness and contrast. The backlight assembly provides uniform backlighting to ensure a clear picture. The module has the characteristics of diversified sizes, standardized interfaces, and strong compatibility. It supports rapid integration into different devices, reduces development costs, and is widely used in scenarios such as human-computer interaction interfaces and instrument displays. For example, the authorization announcement number is CN203720481U, which discloses a universal LCD module.

[0003] The general-purpose LCD modules currently used in outdoor equipment have the following problems:

[0004] First, due to the influence of the low temperature environment, the fluidity of the liquid crystal molecules inside the liquid crystal panel assembly deteriorates, and the response speed slows down, so that the liquid crystal molecules cannot return to their initial positions in time when the state is switched, resulting in residual images, affecting the quality of the image played by the universal liquid crystal module, and affecting the reliability of the use of the universal liquid crystal module;

[0005] Second, in low-temperature environments, frost is easily formed on the surface of the universal LCD module used outdoors. This frost not only interferes with the clarity of the image played by the universal LCD module, but also causes inconvenience to the user in performing interactive operations through the universal LCD module.

[0006] Third, in a dry environment, dry air frequently contacts and rubs against the surface of universal LCD modules, which can easily lead to continuous accumulation of static electricity. When static electricity is released, the high voltage generated instantly can cause devastating damage to electronic components. At the same time, the interference caused by static electricity can also destroy the original orderly arrangement of liquid crystal molecules, thereby causing color spots, afterimages and reduced display contrast. In the long run, these problems seriously affect the service life and working reliability of universal LCD modules.

[0007] Therefore, we propose a universal liquid crystal module to solve the above problems. Summary of the invention

[0013] In the above-mentioned general-purpose liquid crystal module, the ion generation mechanism includes an insulating box fixedly connected to the inner wall of the connection box.

The top end of the air outlet pipe passes through the outer wall of the connection box and is communicated with the annular air guide cavity inside the connection frame. A micro ion generator is fixedly connected to the outer wall of the insulating box. The electrode tip rod of the micro ion generator passes through the inner wall of the insulating box.

[0014] In the above-mentioned general liquid crystal module, the air intake assembly includes a hollow cylinder fixedly communicated with the air intake end of the micro silent air pump. The inner wall of the bottom end of the hollow cylinder is provided with connecting threads. A threaded limiting ring is threadedly connected to the inner wall of the bottom end of the hollow cylinder.

The bottom end of the electric heating tube sequentially passes through a plurality of V-shaped metal mesh plates.

[0017] In the above-mentioned general liquid crystal module, the top end of the air guide pipe extends into the hollow block, and the distance difference between the top end of the air guide pipe and the water inlet end of the drainage thin pipe is 2-3 cm.

[0018] In the above-mentioned general liquid crystal module, a connecting frame is fixedly connected to the inner wall of the box cover, and the outer wall of the connecting frame is in close contact with the inner wall of the connecting box.

[0019] Compared with the existing technology, the advantages of a general liquid crystal module are as follows:

[0020] 1. By setting the microcontroller, the micro silent air pump and the annular air guide cavity, when the general liquid crystal module applied to outdoor equipment is in use, first, the microcontroller controls the micro silent air pump to work. The micro silent air pump sucks air through the air intake assembly. After filtering, the air is then transported to the annular air guide cavity through the micro silent air pump. Finally, the air is sprayed outside the liquid crystal panel assembly through a plurality of air spray holes, and a barrier air film layer is formed outside the liquid crystal panel assembly. The barrier air film layer can block external dust from falling on the surface of the liquid crystal panel assembly, ensuring the clarity of the image played by the liquid crystal panel assembly and facilitating the user to interact with the outdoor equipment through the liquid crystal module.

[0021] 2. Through the set temperature and humidity sensor and the low-temperature protection mechanism, when the temperature value of the surrounding environment of the liquid crystal module detected by the temperature and humidity sensor is lower than the low-temperature threshold preset by the microcontroller, the microcontroller controls the electric heating tube to generate heat to raise the temperature of the air. The heated air is finally sprayed at the liquid crystal panel assembly through the air injection holes, thereby avoiding the situation that the liquid crystal molecules in the liquid crystal panel assembly are affected by low temperature and result in poor fluidity and slow response speed. It ensures that the liquid crystal molecules can return to the initial position in time when the state is switched, thus avoiding the generation of ghosting problems. In addition, the heated air also has the effect of preventing condensation and frosting on the outside of the liquid crystal panel assembly. This mechanism can effectively improve the outdoor protection ability of the liquid crystal module, avoid the generation of ghosting in the image played by the liquid crystal panel assembly due to low temperature, and avoid the formation of a frost layer on the surface of the liquid crystal panel assembly, thereby ensuring the clarity of the image played by the liquid crystal panel assembly and facilitating the user to interact with outdoor devices through the liquid crystal module.

[0022] 3. Through the set ion generation mechanism, when the humidity value detected by the temperature and humidity sensor is lower than the dry threshold preset by the microcontroller, the microcontroller starts the micro ion generator. The micro ion generator ionizes the air through high-voltage discharge, generating a large number of positive and negative ions. When the air carrying a large number of positive and negative ions approaches an electrostatic object, the positive and negative ions neutralize the static electricity. When the air carrying positive and negative ions flows in the annular air guide cavity, it can eliminate the static electricity generated by the friction of dry air on the liquid crystal module itself. Then, when the negative ion air is ejected from the air injection hole, it can also eliminate the static electricity on the surface of the liquid crystal panel assembly, avoid the damage of electronic components in the liquid crystal module caused by the cumulative release of static electricity, and avoid the occurrence of color spots, ghosting and reduced display contrast of the liquid crystal panel assembly due to static electricity, improving the service life and working reliability of the liquid crystal module.

[0023] 4. Through the set thermoelectric cooler, when the humidity value detected by the temperature and humidity sensor is higher than the wet threshold preset by the microcontroller, the microcontroller starts the thermoelectric cooler. The thermoelectric cooler cools the humid air and liquefies the moisture. The moisture in the air is liquefied into water droplets in the low-temperature environment, and the water droplets finally drain out through the drainage capillary tube. Then, the air with reduced humidity is ejected from the air injection hole, avoiding the interference of moisture on the liquid crystal panel assembly and ensuring the reliable display of the image by the liquid crystal panel assembly. This mechanism enables the liquid crystal module to have the function of preventing moisture interference and improves the reliability of use. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 - 7 shown, a general-purpose liquid crystal module includes a liquid crystal panel assembly 1, a drive circuit module 2, and a backlight panel assembly 3. The outer walls of the liquid crystal panel assembly 1 and the backlight panel assembly 3 are fixedly connected to a connection frame 4 together. An annular air guide cavity 5 is opened inside the connection frame 4. A plurality of air jet holes 10 are opened on the inner wall of the connection frame 4, and the hole wall of the air jet hole 10 is communicated with the cavity wall of the annular air guide cavity 5. The air jet side of the air jet hole 10 is located outside the polarizer of the liquid crystal panel assembly 1. A connection box 11 is fixedly connected to the surface of the backlight panel assembly 3. The outer wall of the drive circuit template is fixedly connected to the inner wall of the connection box 11. The wire harness of the drive circuit module 2 passes through the outer wall of the connection box 11 and extends outward;

[0034] A through hole is provided on the side wall of the connection box 11, and a universal wire harness interface 12 is fixedly connected to the hole wall of the through hole. The outer wall of the connection box 11 is connected with a box cover 13. A through hole is provided on the outer wall of the connection box 11, and a temperature and humidity sensor 14 is fixedly connected to the hole wall of the through hole. The inner wall of the box cover 13 is fixedly connected with a connection frame 17. The outer wall of the connection frame 17 is in close contact with the inner wall of the connection box 11. The connection frame 17 can increase the connection area between the box cover 13 and the connection box 11, thereby improving the installation stability of the box cover 13.

[0035] The inner wall of the box cover 13 is fixedly connected with a low-temperature protection mechanism 6. The low-temperature protection mechanism 6 includes a micro silent air extraction pump 61 and a hollow block 67 fixedly connected to the inner wall of the box cover 13. The air inlet end of the micro silent air extraction pump 61 is fixedly communicated with an air inlet assembly 8. A connection through hole matching the bottom end of the air inlet assembly 8 is provided on the lower surface of the connection box 11. The air outlet end of the micro silent air extraction pump 61 is fixedly communicated with a guide air pipe 62. The bottom end of the hollow block 67 is fixedly communicated with a drainage thin pipe 63. The top end of the guide air pipe 62 passes through the inner wall of the bottom end of the hollow block 67. An electric heating tube 64 is fixedly embedded at the top end of the hollow block 67. Fixing through holes are commonly provided on the outer walls of the box cover 13 and the hollow block 67, and heat dissipation fins 65 and a semiconductor refrigeration sheet 66 are fixedly connected to the hole walls of the fixing through holes. The outer wall of the heat dissipation fin 65 is in contact with the heat dissipation side of the semiconductor refrigeration sheet 66. This mechanism enables the universal liquid crystal module to have the functions of preventing low-temperature damage, preventing frost condensation on the liquid crystal screen, and preventing dust from adhering to the liquid crystal screen, improving the clarity of the image played by the liquid crystal panel assembly 1, and improving the reliability of the use of the liquid crystal module.

[0036] A diversion inclined block 15 is fixedly sleeved at the top end of the guide air pipe 62. The bottom end of the diversion inclined block 15 is fixedly connected to the inner wall of the bottom end of the hollow block 67. The diversion inclined block 15 can divert the condensed water into the drainage thin pipe 63. A plurality of V-shaped metal mesh plates 16 are fixedly connected to the inner wall of the hollow block 67. The bottom end of the electric heating tube 64 sequentially passes through the plurality of V-shaped metal mesh plates 16. The refrigeration side of the semiconductor refrigeration sheet 66 is fixedly connected to the side walls of the plurality of V-shaped metal mesh plates 16. The V-shaped metal mesh plates 16 can increase the heat exchange area between the electric heating tube 64 and the semiconductor refrigeration sheet 66, improve the effect of the electric heating tube 64 in heating the air, and improve the effect of the semiconductor refrigeration sheet 66 in cooling and dehumidifying the air. The top end of the guide air pipe 62 extends into the hollow block 67. The distance difference between the top end of the guide air pipe 62 and the water inlet end of the drainage thin pipe 63 is 2.5 cm. The top end of the guide air pipe 62 extends into the hollow block 67 and is higher than the water inlet end of the drainage thin pipe 63. Moreover, due to the limitation of the caliber of the drainage thin pipe 63, 85% - 90% of the air entering the hollow block 67 will quickly enter the hose 72 through the top of the hollow block 67, and the remaining 10% - 15% of the air is discharged from the drainage thin pipe 63. This part of the air can prevent the drainage thin pipe 63 from being blocked.

[0037] The intake assembly 8 includes a hollow cylinder 81 fixedly and communicatively connected to the intake end of the micro silent air extraction pump 61. The inner wall of the bottom end of the hollow cylinder 81 is provided with connecting threads, and a threaded limit ring 82 is threadedly connected to the inner wall of the bottom end of the hollow cylinder 81. A conical fine mesh cover 83 is fixedly connected to the top end of the threaded limit ring 82. The outer wall of the bottom end of the conical fine mesh cover 83 is in close contact with the inner wall of the hollow cylinder 81. The conical fine mesh cover 83 can filter the air entering the interior of the hollow cylinder 81 to prevent the air from carrying large particulate impurities.

[0038] The inner wall of the connection box 11 houses an ion generation mechanism 7 and a microcontroller 9. The ion generation mechanism 7 includes an insulating box 71 fixedly connected to the inner wall of the connection box 11. A hose 72 is fixedly and communicatively connected to the bottom end of the insulating box 71. The bottom end of the hose 72 is fixedly sleeved with the air outlet nozzle at the top end of the hollow block 67 through a pipe clamp. An air outlet pipe 73 is fixedly and communicatively connected to the top end of the insulating box 71. The top end of the air outlet pipe 73 passes through the outer wall of the connection box 11 and is connected to the internal annular air guide cavity 5 in the connection frame 4. An outer wall of the insulating box 71 is fixedly connected with a micro ion generator 74. The electrode tip rod of the micro ion generator 74 passes through the inner wall of the insulating box 71. The micro ion generator 74 generates high voltage through an electric circuit. Then, high voltage discharge occurs at the electrode tip rod of the micro ion generator 74, and the air nearby is ionized to generate a large number of positive and negative ions. When the air carrying a large number of positive and negative ions approaches an electrostatic object, the positive and negative ions neutralize the static electricity, thereby achieving the purpose of eliminating static electricity.

[0039] The micro silent air extraction pump 61, the electric heating tube 64, the semiconductor refrigeration sheet 66, and the micro ion generator 74 are all electrically connected to the output end of the microcontroller 9 through wires. The temperature and humidity sensor 14 is electrically connected to the input end of the microcontroller 9 through a wire. Among them, the model of the microcontroller 9 is RaspberryPiPico2W. This type of controller has the characteristic of rich interfaces, which is convenient for connecting with various sensors and realizing remote transmission of data. The above-mentioned energized devices and electrical connections are all prior arts and will not be elaborated here.

[0040] The operating principle of the present invention is described as follows: When the general-purpose liquid crystal module for outdoor equipment is in use, first, the microcontroller 9 controls the operation of the micro silent air pump 61. The micro silent air pump 61 sucks air through the intake assembly 8. During the process of the air passing through the intake assembly 8, it will be filtered by the conical fine mesh cover 83. After filtration, the air is then transported to the hollow block 67 through the micro silent air pump 61 and the air duct 62. Then, the air in the hollow block 67 enters the annular air guide cavity 5 through the hose 72 and the air outlet pipe 73. Finally, the air is ejected through a plurality of air injection holes 10 outside the liquid crystal panel assembly 1, and a barrier air film layer is formed outside the liquid crystal panel assembly 1. The barrier air film layer can prevent external dust from falling on the surface of the liquid crystal panel assembly 1, ensuring the clarity of the image played by the liquid crystal panel assembly 1 and facilitating the user to interact with the outdoor equipment through the liquid crystal module;

[0041] At the same time, the temperature and humidity sensor 14 will detect the temperature and humidity of the surrounding environment of the liquid crystal module. At the same time, the temperature and humidity sensor 14 sends the detected temperature value and humidity value to the microcontroller 9 in the form of electrical signals. If the detected temperature value is lower than the preset low temperature threshold of the microcontroller 9, the microcontroller 9 controls the electric heating tube 64 to generate heat. The electric heating tube 64 expands the heat conduction area through a plurality of V-shaped metal mesh plates 16, thereby increasing the temperature inside the hollow block 67, ensuring the effect of heating the air injected into the hollow block 67 through the air duct 62. The heated air is finally ejected through the air injection holes 10 at the liquid crystal panel assembly 1, thereby increasing the temperature at the liquid crystal panel assembly 1, and further avoiding the situation that the liquid crystal molecules in the liquid crystal panel assembly 1 have poor fluidity and slow response speed due to the influence of low temperature, ensuring that the liquid crystal molecules can return to the initial position in time during state switching, thereby avoiding the problem of afterimages. In addition, the barrier air film layer formed by the heated air outside the liquid crystal panel assembly 1 also has the effect of preventing condensation of ice and frost, avoiding the condensation of ice and frost layer on the surface of the liquid crystal panel assembly 1 from interfering with the clarity of the image played by the liquid crystal module, and avoiding the condensation of ice and frost layer from interfering with the interaction operation between the user and the outdoor equipment through the liquid crystal module. This mechanism can effectively improve the outdoor protection ability of the liquid crystal module, avoid the generation of afterimages in the image played by the liquid crystal panel assembly 1 due to low temperature, and avoid the generation of ice and frost layer on the surface of the liquid crystal panel assembly 1, thereby ensuring the clarity of the image played by the liquid crystal panel assembly 1 and facilitating the user to interact with the outdoor equipment through the liquid crystal module;

[0042] When the humidity value detected by the humidity and temperature sensor 14 is lower than the drying threshold preset by the microcontroller 9, the microcontroller 9 activates the micro ion generator 74. The micro ion generator 74 generates high voltage through a circuit. Then, high voltage discharge occurs at the electrode tip rod of the micro ion generator 74 inside the insulating box 71, and the nearby air is ionized to generate a large number of positive and negative ions. When the air carrying a large number of positive and negative ions approaches an electrostatic object, the positive and negative ions neutralize the static electricity. When the air carrying positive and negative ions flows in the annular air guiding cavity 5, it can eliminate the static electricity generated by the friction of dry air on the liquid crystal module itself. Then, when the negative ion air is ejected from the air ejection hole 10, it can also eliminate the static electricity on the surface of the liquid crystal panel assembly 1, avoiding damage to the electronic components in the liquid crystal module caused by the cumulative release of static electricity, and avoiding the occurrence of color spots, afterimages, and reduced display contrast of the liquid crystal panel assembly 1 due to static electricity, improving the service life and working reliability of the liquid crystal module;

[0043] When the humidity value detected by the humidity and temperature sensor 14 is higher than the humidity threshold preset by the microcontroller 9, the microcontroller 9 activates the semiconductor refrigeration sheet 66. The semiconductor refrigeration sheet 66 cools a small range of cavities inside the hollow block 67 through the V-shaped metal mesh plate 16. Then, after the high-humidity air transported by the air duct 62 enters the low-temperature hollow block 67, the moisture in the air is liquefied into water droplets by the low-temperature environment. The water droplets drip onto the bottom of the hollow block 67 through the V-shaped metal mesh plate 16 and finally drain out through the drainage capillary 63 and are discharged to the outside of the housing of the outdoor device. Then, the air with reduced humidity is ejected from the air ejection hole 10 to avoid the liquid crystal panel assembly 1 being interfered by moisture and ensure the reliable image playback of the liquid crystal panel assembly 1. This mechanism enables the liquid crystal module to have the function of preventing moisture interference and improves the reliability of use.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
