TECHNICAL FIELD
[0001] The utility model relates to touch -sensitive screen technical field, especially touch -sensitive screen liquid crystal display module. BACKGROUND
[0002] With the rapid development of information technology, touch screen liquid crystal display module (LCD) as the important medium of information interaction, in smart mobile phone, tablet computer, industrial control panel etc. Many fields have been widely used. The traditional touch screen liquid crystal display module is mainly composed of liquid crystal display screen and touch sensing layer, aims at realizing the intuitive interaction between user and equipment. However, with the improvement of user's requirement to equipment performance, especially the increasing demand for display effect, durability and heat dissipation efficiency, the traditional design gradually exposes some shortcomings. For example, the early design performs poorly in high brightness environment, especially in outdoor or strong light direct radiation, because of the poor visibility caused by insufficient brightness of backlight or light scattering problem, which affects user experience. In addition, the heat generated under long time use is difficult to dissipate effectively, which not only accelerates the aging of electronic components, but also may cause the problem of screen display quality decline or damage. Therefore, how to improve the display effect and heat dissipation performance of touch screen liquid crystal display module has become the focus of current research.
[0003] In the prior art, in order to improve the above problems, some solutions have been put forward, such as increasing the number of LED lamp beads to enhance the brightness of backlight, using more efficient heat conduction material to strengthen the heat dissipation effect, etc. However, these improvement measures often accompany the problems of cost increase, structure complexity rise and volume increase, which limits its application in portable devices. Especially in the aspect of efficient heat dissipation, although there are various heat dissipation schemes on the market, most of them fail to balance the light and thin design and efficient heat dissipation, resulting in many challenges in the actual application of products. Moreover, for the special needs of outdoor use, most of the existing products have not been able to provide an ideal solution, such as maintaining clear and visible display effect under strong sunlight. In summary, there is an urgent need in the market for a new type of touch screen liquid crystal display module which can guarantee excellent display performance and good heat dissipation management, and has certain anti-environmental interference ability. SUMMARY
[0004] In view of the deficiencies in the prior art, the utility model provides a kind of touch screen liquid crystal display module, including installation casing, the front of installation casing is equipped with first installation aluminum frame, the inside installation of first installation aluminum frame is equipped with light guide plate, the left front side and right front side of first installation aluminum frame are equipped with light emitting module respectively, the front side of light emitting module is equipped with second installation aluminum frame, the inside installation of second installation aluminum frame is equipped with touch screen, the upper portion and lower portion of light emitting module are equipped with metal plate respectively, the rear portion of metal plate is equipped with first heat conduction plate, the rear portion of first heat conduction plate is equipped with second heat conduction plate, and metal plate is connected with first heat conduction plate and second heat conduction plate by heat conduction copper pipe.
[0005] Further, the left side and the right side of the metal plate are respectively welded with a connecting lug, and the connecting lug is connected with the light emitting module by a screw.
[0006] Further, the front side and the rear side of the light emitting module are respectively bonded with a shock-absorbing rubber pad, and a plurality of LED lamp beads are mounted on one side of the light emitting module.
[0007] Further, the upper portion of the metal plate is fixedly connected with a plurality of pins, and the first installation aluminum frame is provided with corresponding insertion grooves.
[0008] Further, a plurality of hexagonal holes are uniformly formed on the first heat conduction plate, and a plurality of mounting holes are formed on the left side and the right side of the first heat conduction plate.
[0009] Further, the first heat conduction plate is connected with the installation casing by a bolt, the installation casing is provided with a threaded hole, and the left side and the right side of the installation casing are respectively fixedly connected with a threaded sleeve.
[0010] Compared with the prior art, the utility model has the beneficial effects that by setting the metal plate and connecting it with the first heat conduction plate and the second heat conduction plate through the heat conduction copper pipe, an efficient heat dissipation mechanism is realized. In the touch screen liquid crystal display module, heat generation is one of the important factors affecting the performance and service life of the equipment. Especially when working in high-brightness mode, the light emitting module will generate a large amount of heat.
[0011] By introducing the metal plate and connecting it with the first heat conduction plate and the second heat conduction plate through the heat conduction copper pipe, an efficient heat dissipation path is formed. Specifically, when the light emitting module generates heat, the heat is first absorbed by the metal plate, and then rapidly conducted to the first heat conduction plate and the second heat conduction plate through the heat conduction copper pipe with extremely high heat conduction efficiency. This design not only improves the overall heat conduction efficiency of the structure, but also ensures that the heat can be quickly dissipated from the core components to the outside, avoiding the occurrence of local overheating. In addition, due to the adoption of the multi-stage heat conduction plate design, the heat can be more evenly distributed, further improving the heat dissipation efficiency.
[0012] The heat dissipation mechanism functions to maintain the stability of the internal temperature of the touch screen liquid crystal display module, which is crucial for ensuring the working performance of the electronic components. For example, long-time operation in a high-temperature environment can cause the light decay of the LED lamp beads to be more serious or shorten the service life thereof, and effective heat dissipation measures can effectively alleviate this problem. By maintaining a lower and stable temperature environment, the material expansion and contraction caused by temperature difference can also be reduced, thereby reducing the influence on the touch screen and its peripheral components and enhancing the mechanical stability of the entire device. This design not only prolongs the overall service life of the equipment, but also enables the touch screen liquid crystal display module to maintain excellent display effect and response speed under various complex working conditions due to proper temperature control, thereby meeting the user's demand for high-performance display equipment.

[0025] Working principle: when the equipment is powered on, the light emitting module 9 starts to work, and a plurality of LED lamp beads 13 in the light emitting module 9 emit light. The light is uniformly distributed in the entire display area through the light guide plate 18, thereby providing a backlight source for the liquid crystal display screen. In order to ensure the effective transmission of light and reduce the loss, the light guide plate 18 is accurately installed in the first mounting aluminum frame 11.
