Description

Technical Field

[0001] This application relates to the field of liquid crystal display packaging technology, and in particular to a moisture-proof, dust-proof, and light-leakage-proof LCD panel. Background Technology

[0002] LCD panels are widely used in electronic devices, especially in scenarios where both display functionality and protective performance are required. As electronic products trend towards thinner, lighter, and more multifunctional designs, achieving good sealing while maintaining aesthetics has become a crucial challenge.

[0003] To address this challenge, the industry typically employs various methods to solve similar problems. For example, adding a sealing ring or using adhesive to secure the transparent cover to the display screen; another common approach is to design special structural components, such as adding baffles or light shields inside the casing to block unwanted light leakage; additionally, there are methods that use special materials to fill gaps, such as foam pads or other elastic substances. All these measures aim to improve the overall sealing of the device. However, the appropriate technical approach will be chosen based on the specific product requirements during implementation.

[0004] While the aforementioned existing technologies can achieve a certain degree of sealing, thus preventing light leakage, dust, and moisture, they still have shortcomings in practical applications. Especially for miniaturized, highly integrated devices, traditional sealing methods often struggle to completely eliminate minute gaps caused by assembly errors, leading to incomplete sealing. Therefore, a new design solution is urgently needed that can effectively improve these issues without significantly increasing size, to meet the requirements of modern precision electronic equipment. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a moisture-proof, dust-proof, and light-leakage-proof LCD panel, which adopts the following solution:

[0006] A moisture-proof, dust-proof, and light-leakage-proof LCD panel includes: a transparent cover plate with a first protrusion on one side and a second protrusion on the opposite side; wherein the transparent cover plate is embedded in a viewing window of a housing via the first protrusion; a frame fitting fitted onto the second protrusion; a display screen located on the side of the frame fitting away from the transparent cover plate, wherein the frame fitting abuts against the transparent cover plate and the display screen respectively, forming a sealed space; and a control board located on the side of the display screen away from the frame fitting, for fixing within the housing, wherein the display screen is fixed to the control board.

[0007] By adopting the above technical solution, the first protrusion of the transparent cover is embedded in the viewing window of the housing, achieving a stable connection between the module and the housing; the second protrusion, in conjunction with the design of the frame, ensures the sealing between the transparent cover and the display screen, effectively preventing light leakage, and the frame also prevents external impurities from entering. The combined design of the display screen and control board not only simplifies the installation process but also improves the overall stability of the module.

[0008] Optionally, the transparent cover plate further includes a third boss and a fourth boss on the same side as the second boss, and a positioning groove for accommodating the rubber frame is formed between the second boss and the third boss and the fourth boss.

[0009] By adopting the above technical solution, a third and fourth protrusion are added to the transparent cover plate, which, together with the second protrusion, form a positioning groove. This precisely defines the position of the frame component, ensuring its installation stability, thereby improving assembly efficiency and reducing assembly errors. Simultaneously, this structural design helps enhance light leakage prevention performance, avoiding light leakage problems caused by frame component misalignment.

[0010] Optionally, the third boss and the fourth boss are located on the same side of the second boss, and the third boss and the fourth boss are at the same distance from the second boss to form the positioning groove.

[0011] By adopting the above technical solution, the third and fourth protrusions on the transparent cover are located on the same side of the second protrusion and maintain the same distance from it, thus forming a positioning groove. This design can precisely define the position of the frame component, ensuring its stable embedding and preventing displacement during assembly, thereby improving the overall sealing performance of the module and effectively preventing light leakage. At the same time, this structural design simplifies the assembly process and improves production efficiency.

[0012] Optionally, the display screen is provided with a plug-in protrusion on its corner for insertion into the control board, and the control board is provided with a plug-in hole corresponding to the plug-in protrusion.

[0013] By adopting the above technical solution, a stable connection between the display screen and the control board is achieved. Specifically, the design of the insertion protrusion allows the display screen to be precisely inserted into the insertion hole on the control board, thereby improving assembly efficiency and enhancing structural stability. This design effectively avoids functional abnormalities or light leakage caused by loosening, while simplifying the installation process and improving product reliability and service life.

[0014] Optionally, the insertion protrusions are provided in pairs, located at opposite corners of the display screen.

[0015] By adopting the above technical solution, a stable connection between the display screen and the control board is achieved. Specifically, by setting two plug-in protrusions located diagonally across the display screen, the stress points can be effectively distributed, avoiding loosening or detachment caused by single-point stress, thereby improving connection stability and facilitating assembly and disassembly.

[0016] Optionally, the first boss is smaller than the size of the second boss.

[0017] By adopting the above technical solution, it is ensured that the frame fitting around the second boss will not obstruct the viewing area of ​​the first boss. Furthermore, this design allows the first boss to be more precisely embedded in the viewing window of the housing, improving the overall structural stability and sealing, and effectively preventing light leakage.

[0018] Optionally, the frame is made of foam.

[0019] By adopting the above technical solution, using foam material as the frame component can effectively improve sealing performance and prevent light leakage. The foam material has good elasticity and compressibility, and when compressed, it can tightly fit the gap between the transparent cover and the display screen, thereby enhancing the overall airtightness of the module and preventing external ambient light from entering or internal light source leakage. At the same time, this material also has a certain cushioning effect, helping to protect internal components from vibration.

[0020] Optionally, the frame is bonded to the transparent cover and abuts against the display screen.

[0021] By adopting the above technical solution, a firm connection between the frame and the transparent cover is achieved, enhancing the overall stability of the module and effectively preventing loosening caused by vibration or external impact. Simultaneously, the bonding method helps improve sealing performance, further reducing the possibility of light leakage, thereby enhancing the product's optical performance and reliability.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By embedding the first protrusion of the transparent cover into the viewing window of the housing, and using the plastic frame to cooperate with the second protrusion, and the plastic frame simultaneously abutting against the transparent cover and the display screen, a sealed space is formed, which effectively reduces the small gaps caused by assembly errors, thereby significantly improving the overall sealing performance of the module, preventing light leakage, and also playing a role in dustproofing and moisture-proofing.

[0024] 2. The first boss is smaller than the second boss, ensuring that the frame fitting around the second boss does not obstruct the viewing area of ​​the first boss. This design also allows the first boss to be more precisely embedded in the viewing window of the housing, improving the overall structural stability and sealing, and effectively preventing light leakage.

[0025] 3. The display screen is precisely positioned by the plug-in protrusions and the plug-in holes on the control board, which simplifies the assembly process and enhances the relative positional stability between the components, ensuring the reliability of the entire module during use.

[0033] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0034] Hereinafter, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0035] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0036] See Figure 1 and Figure 2 The LCD panel disclosed in this application is moisture-proof, dust-proof, and light-proof, comprising: a transparent cover plate 10, a frame 20, a display screen 30, and a control board 40. The transparent cover plate 10, the frame 20, and the display screen 30 cooperate with each other to form a sealed space, achieving a good light-proof effect while also providing dust-proof and moisture-proof effects.

[0037] The transparent cover plate 10 includes a first protrusion 11, a second protrusion 12, a third protrusion 13, and a fourth protrusion 14, see [reference]. Figure 3 and Figure 4 The first protrusion 11 is located on one side of the transparent cover plate 10, and the size of the first protrusion 11 is slightly smaller than the opening size of the viewing window 51 on the outer shell 50. This ensures that the first protrusion 11 will not be excessively squeezed and deformed when embedded in the viewing window 51, and that there will not be an excessively large gap between them. See [link to relevant documentation]. Figure 5 .

[0038] See Figure 4 The second protrusion 12 is located on the other side of the transparent cover plate 10, that is, facing the inside of the outer shell 50, and is larger in size than the first protrusion 11. The plastic frame 20 is used to fit on the second protrusion 12 so that it is located outside the second protrusion 12 and will not block the viewing area of ​​the first protrusion 11.

[0039] See Figure 3 and Figure 4 The third boss 13, the fourth boss 14 and the second boss 12 are located on the same side, and the third boss 13 and the fourth boss 14 are located on the same side of the second boss 12 and at the same distance, so as to form a positioning groove 15 for accommodating the glue frame 20 and to accurately position the glue frame 20.

[0040] See Figure 2The frame 20 is made of foam, which has excellent airtight properties and can effectively improve the sealing performance and prevent light leakage. The frame 20 is bonded to the transparent cover 10 by adhesive and abuts against the display screen 30 to form a sealed space, which can prevent moisture from entering the viewing window and avoid visual blurring caused by moisture, thus achieving a moisture-proof effect.

[0041] The frame 20, made of foam material, has good elasticity and compressibility. When compressed, it can tightly fit the gap between the transparent cover 10 and the display screen 30, thereby enhancing the overall airtightness of the module and preventing external ambient light from entering or internal light sources from escaping. At the same time, this material also has a certain cushioning effect, helping to protect internal components from vibration.

[0042] See Figure 2 The display screen 30 is located on the side of the frame 20 away from the transparent cover plate 10, and has insertion protrusions 31 on its corners for insertion into the control board 40. The control board 40 has corresponding insertion holes 41. There are two insertion protrusions 31 located at opposite corners of the display screen 30, which facilitates quick and accurate insertion into the insertion holes 41.

[0043] See Figure 2 The control board 40 is located on the side of the display screen 30 away from the frame 20, and is used to fix it inside the housing 50 and to fix the display screen 30 thereon. Thus, through the reasonable combination of the transparent cover 10, the frame 20, the display screen 30 and the control board 40, an overall structure with good light leakage prevention effect is formed.

[0044] In summary, the LCD panel disclosed in this application, which is moisture-proof, dust-proof, and light-leakage-proof, features a transparent cover 10 embedded in the viewing window 51 of the outer casing 50 via a first protrusion 11. Through the tight fit between the frame 20, the second protrusion 12, and the display screen 30, a stable, sealed environment is created, significantly improving the module's light-leakage prevention capability under miniaturization conditions. The foam frame 20, when compressed, tightly seals the gap between the transparent cover 10 and the display screen 30, thereby enhancing the overall airtightness of the module, preventing external ambient light from entering or internal light source leakage, while also providing dust and moisture protection. Furthermore, the material of the frame 20 also provides cushioning, helping to protect internal components from vibration. The display screen 30 is precisely positioned with the insertion protrusion 31 and the insertion hole 41 on the control board 40, simplifying the assembly process while ensuring accurate relative positions between components and reducing the risk of light leakage due to assembly deviations.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
