[0030] As described in the background, the structure design of the conventional LCD display module is usually to adhere the LCD display component to the back of the transparent cover plate. This kind of laminated design is simple and direct, but it exposes a series of problems in actual application. This kind of laminated design makes the LCD display component exposed and protruding outward, so that the module is easily affected by the external environment before being installed on the device shell, thereby affecting its service life.

[0031] In order to solve this technical problem, the present application provides an LCD display module.

[0032] Specifically, please refer to Figures 1-5 The LCD display module specifically comprises:

[0033] The back surface of the cover plate body 1 is provided with a containing groove 3, and the containing groove 3 is provided with an LCD display structure 2.

[0034] The LCD display module has the advantages that the containing groove 3 is arranged on the back surface of the cover plate body 1, and the LCD display structure 2 is arranged in the containing groove 3, so that the LCD display structure 2 is effectively prevented from protruding outward, the cover plate body 1 can effectively protect the LCD display structure 2 before the module is mounted on the equipment shell, the service life of the module is prolonged, the overall thickness of the module is effectively reduced by arranging the LCD display structure 2 in the containing groove 3, and this is of great significance for electronic products pursuing lightweight and miniaturized design.

[0035] In order for those skilled in the art to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in conjunction with the drawings.

[0036] It should be noted that the embodiments in the present application and the features and technical schemes in the embodiments can be combined with each other without conflict.

[0037] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0038] Embodiment one of the LCD display module of the present application

[0039] Please refer to Figures 1-5 The LCD display module comprises a cover plate body 1, the back surface of the cover plate body 1 is provided with a containing groove 3, the containing groove 3 is provided with an LCD display structure 2, the LCD display structure 2 comprises a backlight assembly 201 arranged in the containing groove 3, and the inner side surface of the backlight assembly 201 is provided with a display assembly; the containing groove 3 is arranged on the back surface of the cover plate body 1, and the LCD display structure 2 is arranged in the containing groove 3, so that the LCD display structure 2 is effectively prevented from protruding outward, the cover plate body 1 can effectively protect the LCD display structure 2 before the module is mounted on the equipment shell, the service life of the module is prolonged, the overall thickness of the module is effectively reduced by arranging the LCD display structure 2 in the containing groove 3, and this is of great significance for electronic products pursuing lightweight and miniaturized design.

[0040] Further, as Figure 2 , Figure 3 and Figure 5As shown, the outer periphery of the LCD display structure 2 leaves a gap with the inner wall of the accommodating groove 3, and the gap is filled with sealing glue 5. In the use environment of electronic products, dust is everywhere, and small dust particles may enter the module inside through various gaps. If the dust adheres to the LCD display structure 2, it will scatter light, reduce the clarity and contrast of the display, and affect the visual effect. In addition, water vapor is also a potential threat, especially in a humid environment. Once water vapor enters the module inside, it may condense on the surface of electronic components, causing short circuit, corrosion and other problems, which seriously affect the performance and life of the module. The sealing glue 5 filled in the gap can effectively prevent the invasion of dust and water vapor, ensure that the inside of the module is always in a relatively clean and dry environment, and ensure the long-term stability of the display effect.

[0041] The sealing glue 5 filled in the gap can also buffer and fix the LCD display structure 2 to some extent, so that it can remain stable when subjected to external force, reduce the risk of damage to internal components due to shaking, and ensure that the module can still work normally in a complex use environment.

[0042] Embodiment two of the LCD display module of the utility model

[0043] Further, as shown in Figure 2 and Figure 5 , the display assembly includes a second polarizing plate 206 attached to the backlight assembly 201. The second polarizing plate 206 has a first polarizing plate 203 disposed on the side away from the backlight assembly 201. The first polarizing plate 203 and the second polarizing plate 206 are disposed with an incell LCD. The incell LCD is an in-cell integrated touch control function LCD display screen. The cooperation of the first polarizing plate 203 and the second polarizing plate 206 with the incell LCD can accurately control the polarization of light. The second polarizing plate 206 first performs preliminary screening and adjustment on the light emitted by the backlight assembly 201, removing some unnecessary light components. Then the light passes through the incell LCD. The liquid crystal molecules in the incell LCD further modulate the light under the action of the electric field. Finally, the first polarizing plate 203 performs the final polarization processing on the light, so that the light can propagate according to the predetermined direction and intensity. This accurate light control can significantly improve the contrast of the display picture, making the details of the picture clearer and more distinguishable, thereby providing users with a better visual experience. Whether it is watching high-definition videos, browsing pictures or performing other operations that require high-quality display, better results can be obtained.

[0044] Further, as shown in Figure 5As shown, the in-cell LCD includes a lower glass sheet 205 connected with the second polarizer 206 and an upper glass sheet 204 connected with the first polarizer 203. The upper and lower glass sheets 204 and 205, as important components of the in-cell LCD, provide stable accommodation space and physical support for liquid crystal molecules. Their connection with the first and second polarizers 203 and 206 makes the entire display structure more stable. The connection of the lower glass sheet 205 with the second polarizer 206 ensures stable polarization adjustment of light before entering the in-cell LCD. The connection of the upper glass sheet 204 with the first polarizer 203 ensures that the light modulated by the liquid crystal can be accurately output through the first polarizer 203. This stable structure can effectively prevent the abnormal flow or uneven distribution of liquid crystal molecules due to external factors such as vibration and temperature change, ensuring the flatness and stability of the display image and avoiding display abnormalities such as flickering and stripes, so that the display effect remains consistent.

[0045] Further, as shown in Figure 5 The first polarizer 203 is provided with a connecting piece away from the upper glass sheet 204. The connecting piece is used to connect the first polarizer 203 and the inner wall of the accommodating groove 3. By arranging the connecting piece between the first polarizer 203 and the inner wall of the accommodating groove 3, the first polarizer 203 can be firmly fixed at a predetermined position, and the position of the entire display assembly in the module is more stable. This fixing effect can effectively resist the influence of external force on the display assembly, reduce display failures caused by external force, and improve the reliability of the module in complex use environment.

[0046] Further, as shown in Figure 5 The connecting piece is OCA optical adhesive 202, which is attached between the inner wall of the accommodating groove 3 and the first polarizer 203. OCA optical adhesive 202 has high transparency, with extremely high transmittance in the visible light range, almost no attenuation or scattering of light propagation. This means that light can pass through OCA optical adhesive 202 smoothly after passing through the first polarizer 203, without color deviation, brightness reduction and other problems affecting display effect caused by the presence of adhesive. Under high-quality display requirements, this high-transparency adhesive can ensure that the original color and brightness of the display image are faithfully presented, providing users with clear and realistic visual experience.

[0047] At the same time, OCA optical adhesive 202 has good adhesion, which can form a firm connection between the inner wall of the accommodating groove 3 and the first polarizer 203. This adhesion can maintain the stability of the display assembly under normal use conditions, providing a strong guarantee for the stability of the entire display module in complex use environment.

[0048] Further, as shown in Figure 5 The sealing glue 5 is wrapped between the outer circumferential sides of the backlight assembly 201, the OCA optical glue 202, the first polarizing plate 203, the upper glass 204, the lower glass 205 and the second polarizing plate 206. In various use scenarios, the display module faces various potential hazards. From the external environment, dust may enter the module from various directions, which not only affects the light propagation effect of the optical element, but also may be adsorbed on the surface of the electronic element due to static electricity of the dust particles, thereby interfering with the normal work of the circuit. Water vapor may also penetrate from different gaps and corrode the electronic element, affecting its electrical performance and service life. The wrapping of the sealing glue 5 forms a sealed environment, which wraps the key display assembly therein, prevents dust and water vapor from entering from various angles, and ensures that the display assembly is always in a clean and dry working environment to maintain its best performance state.

[0049] Further, as shown in Figures 1-3 The main screen FPC 4 is bound to the lower glass 205, one end of the main screen FPC 4 extends out of the sealing glue 5 and extends to the outside of the accommodating groove 3. The main screen FPC 4 is a key medium for signal transmission between the display module and the equipment mainboard, and is responsible for transmitting the control signal from the mainboard to the display module and feeding back the image data generated by the display module to the mainboard.

[0050] Embodiment three of the LCD display module

[0051] Further, the cover plate body 1, the sealing glue 5 and the back surface of the backlight assembly 201 are provided with a scratch-resistant and heat-conducting coating. The scratch-resistant and heat-conducting coating can be an aluminum oxide ceramic coating. The aluminum oxide ceramic has very high hardness, and the Mohs hardness can reach about 9, has excellent wear resistance, can well prevent scratching, and also has heat conduction capacity. The aluminum oxide powder can be sprayed between the cover plate body 1, the sealing glue 5 and the back surface of the backlight assembly 201 by a plasma spraying process to form a coating, so as to achieve the effects of scratch resistance and heat conduction.

[0052] Further, the thickness of the cover plate body 1 is 2.5 mm, the thickness of the OCA optical glue 202 is 0.1 mm, the thickness of the first polarizing plate 203 is 0.1 mm, the total thickness of the upper glass 204 and the lower glass 205 is 0.3 mm, the thickness of the second polarizing plate 206 is 0.1 mm, and the thickness of the backlight assembly 201 is 1.2 mm.

[0053] The whole stack is composed of the cover plate body 1, OCA optical glue 202, the first polaroid 203, the upper glass 204, the lower glass 205 and the second polaroid 206, wherein the cover plate body 1 is made of aluminum-silicon material glass with a thickness of 2.5 mm; the cover plate body 1 has a viewing area and a non-viewing area, the size of the accommodating groove 3 is larger than the size of the viewing area, and the position of the sealing glue 5 is within the range of the non-viewing area.

[0054] The accommodating groove 3 is arranged on the back surface of the cover plate body 1 by chemical etching, for placing the LCD display structure 2; the depth of the accommodating groove 3 is determined by the total thickness of the LCD display structure 2, for example, in the embodiment, the depth of the accommodating groove 3 needs to be greater than 1.8 mm, and the length and width of the accommodating groove 3 need to be increased by 1 mm based on the length and width of the backlight assembly 201, and the gap of 1 mm around is used for placing the sealing glue 5; in addition, the area of the back surface of the cover plate body 1 except the viewing area needs to be silk-screen printed with black or other color ink.

[0055] Obviously, the above-described embodiments are only some embodiments of the present application, not all embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application.
