Description
Technical Field
[0001] The utility model relates to the technical field of LCD display screens, in particular to an LCD display screen with an I-shaped sealing structure. Background Art
[0002] Liquid Crystal Display (LCD) is a type of flat-panel display, primarily used for television and computer screen displays. LCDs use a liquid crystal solution between two polarized materials. When an electric current passes through the liquid, the crystals rearrange, creating an image.
[0003] However, as LCD displays operate for extended periods of time or in environments with high temperature and humidity, the display on the sealed end of the product may fade or even become scratched, which may lead to customers questioning the product quality and even negatively impacting the quality and brand of the assembled device.
[0004] For example: the sealing end design of traditional products is usually in the shape of an "eight". Different shapes of glue blocking lines may be set in the "eight-shaped seal" according to actual needs to control the flow and infusion of liquid crystal. When the liquid crystal infusion reaches the inflation step, the "eight-shaped seal" is subjected to dual pressure from the outside and the inside of the box, which may cause the liquid crystal molecules in the liquid crystal box space to move at uneven speeds from both sides of the glue blocking line due to the pressure difference between the vacuum pressure in the liquid crystal box and the external inflation pressure, which may cause uneven distribution of liquid crystal, resulting in poor flushing and affecting the overall display effect of the display screen. Utility Model Content
[0005] The utility model discloses an LCD display screen with an I-shaped sealing structure, which aims to solve the technical problem that when the LCD display screen works for a long time or works in an environment with excessively high temperature and humidity, the display content on the sealed end of the product may fade or even be missing, which may cause customers to question the quality of the product and even have a negative evaluation of the quality and brand of the later assembled whole machine.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] An LCD display screen with an I-shaped sealing structure includes a display screen body, wherein the display screen body is provided with an assembly area, a sealing area and two limit plates, and further includes: a glue blocking line is provided on the side of the sealing area close to the display screen body, the glue blocking line is a semi-enclosed structure, and two limiting seams and two partition components are provided on the glue blocking line, wherein the limiting seams separate the longitudinal section of the glue blocking line into an "I" shape.
[0008] The above-mentioned technical solution can better prevent external moisture, dust and other harmful substances from invading the interior of the LCD product, thereby extending the service life of the LCD product, ensuring sufficient glue coverage, and avoiding the problem of liquid crystal contamination when the display screen body is poured into the liquid crystal and the fading of the LCD sealing pen tip due to insufficient UV of the sealing glue. Specifically, when in use, the working component is installed in the assembly area, the glue blocking line is installed on the sealing area, and then the display screen body is placed on the gluing platform. The limiting seam in the glue blocking line is limited by the partition component, and the outer walls on both sides of the glue blocking line are limited by two limiting plates. Then, the gluing device is used to glue along the limiting seam on the "I"-shaped glue blocking line set in this solution. The design principle of the I-shaped seal is to use the I-shaped structure to enhance the compressive performance of the box body, which can effectively disperse external forces and evenly distribute pressure, thereby improving the strength and stability of the seal. Especially in an environment with excessively high temperature and humidity, the I-shaped seal can better resist such deformation due to its structural stability, thereby protecting the liquid crystal layer and electronic components inside the LCD product from damage.
[0009] In a preferred solution, two stabilizing strips distributed at equal distances are installed on the inner wall on the opposite side of the limiting slit, and the two stabilizing strips divide the limiting slit into three glue dispensing areas.
[0010] According to the attached figure, the stabilizing bar is a low structure in the middle and high on both sides. This arrangement makes it easy for the glue spotting areas separated by the stabilizing bar to be connected through the top of the stabilizing bar. When the LCD display is subsequently packaged with glue, the glue in different glue spotting areas can be flexibly diverted through the top of the stabilizing bar to avoid the problem of local overflow of the sealing glue.
[0011] In a preferred solution, the partition assembly includes two mounting bars, which are fixedly connected to the top outer wall of the display screen body; a mounting groove is provided on the top outer wall of the mounting bar; a moving block is provided inside the mounting groove; a limiting groove is provided on one side outer wall of the moving block; a fixing groove is provided on one side outer wall of the limiting groove; three return springs are provided on the inner wall of the fixing groove; a baffle is provided at one end of the return spring; and the top outer wall of the mounting bar is connected to a fixing column by a thread.
[0012] When in use, first press the baffle bar continuously with your fingers to squeeze the three return springs connected to the outer wall of one side of the baffle bar and retract them into the limit groove. Then place the moving block in the installation groove. After it is completely placed in, release the squeeze on one side of the baffle bar. Under the elastic force of the return spring, push the baffle bar to a state flush with one side of the installation bar. Then tighten the four fixing columns, so that the fixing columns limit the installation bar downwards and limit the upper part of the rubber line at the same time.
[0013] As can be seen from the above, an LCD display screen with an I-shaped sealing structure includes a display screen body, wherein the display screen body is provided with an assembly area, a sealing area and two limit plates, and further includes: a glue blocking line is provided on the side of the sealing area close to the display screen body, the glue blocking line is a semi-enclosed structure, and two limiting seams and two partition components are provided on the glue blocking line, and the limiting seams separate the longitudinal section of the glue blocking line into an "I" shape. The LCD display screen with an I-shaped sealing structure provided by the utility model can better prevent external moisture, dust and other harmful substances from invading the interior of the LCD product, thereby extending the service life of the LCD product, ensuring sufficient glue coverage, improving the tightness of the sealing, and avoiding the problem of liquid crystal contamination when the display screen body is poured with liquid crystal and the problem of fading of the LCD sealing pen tip due to insufficient UV of the sealing glue.

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.
[0020] The utility model discloses an LCD display screen with an I-shaped sealing structure, which is mainly used in scenarios where the display content on the sealed end of the product may fade or even be missing when the LCD display screen is operated for a long time or in an environment with excessively high temperature and humidity, which may cause customers to question the quality of the product and even have a negative evaluation of the quality and brand of the later assembled whole machine.
[0021] Reference Figure 1 and Figure 2 An LCD display screen with an I-shaped sealing structure includes a display screen body 1, on which an assembly area 2, a sealing area 9 and two limit plates 4 are provided. The display screen body 1 also includes: a glue blocking line 3 is provided on the side of the sealing area 9 close to the display screen body 1, and the glue blocking line 3 is a semi-enclosed structure. Two limiting seams 5 and two partition components are provided on the glue blocking line 3. The limiting seams 5 separate the longitudinal section of the glue blocking line 3 into an "I" shape.
[0022] It should be emphasized that according to the Figure 2 The black area is marked as the glue line 3 area.
[0023] It should be noted that UV sealing glue, also known as ultraviolet curing glue, is an adhesive that is cured by ultraviolet radiation. The curing of UV glue requires a certain amount of time. If the irradiation time is too short, the sealing glue may not be completely cured, which may cause the LCD sealing pen tip to fade. Therefore, when selecting sealing materials, glue blocking lines 3 and partition components, give priority to materials with weaker ultraviolet absorption to improve the curing effect of the sealing glue.
[0024] The longitudinal length of the two limiting slits 5 is two-thirds of the total longitudinal length of the rubber blocking line 3 .
[0025] During the specific implementation process, the limiting plate 4 is an "L"-shaped structure. This setting is convenient for limiting the outer walls of both sides of the rubber blocking line 3 near the vertical angle, and is used in conjunction with the partition component to achieve the purpose of maintaining a straight state of the rubber blocking line 3 during installation and preventing movement or skewing.
[0026] Specifically, when in use, the working element is installed in the assembly area 2, the glue blocking line 3 is installed in the sealing area 9, and then the display screen body 1 is placed on the gluing platform. The limiting seam 5 in the glue blocking line 3 is limited by the partition component, and the outer walls on both sides of the glue blocking line 3 are limited by two limiting plates 4. Then, the gluing device is used to glue along the limiting seam 5 on the "I"-shaped glue blocking line 3 set in this scheme. The design principle of the I-shaped sealing is to use the I-shaped structure to enhance the compressive performance of the box body, which can effectively disperse external forces and evenly distribute pressure, thereby improving the strength and stability of the seal. Qualitatively, especially in an environment with excessively high temperature and humidity, the I-shaped seal can better resist such deformation due to its structural stability, thereby protecting the liquid crystal layer and electronic components inside the LCD product from damage, and the I-shaped seal design usually has a tighter contact surface, which can better prevent external moisture, dust and other harmful substances from invading the interior of the LCD product, thereby extending the service life of the LCD product, ensuring sufficient glue coverage, and avoiding the problem of liquid crystal contamination when the display screen body 1 is poured into the liquid crystal and the fading of the LCD sealing pen tip caused by insufficient UV of the sealing glue.
[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, two equidistantly distributed stabilizing strips 7 are installed on the inner wall of the opposite side of the limiting slit 5, and the two stabilizing strips 7 divide the limiting slit 5 into three dispensing areas.
[0028] Specifically, according to the attached Figure 1 The stabilizing strip 7 is a low-middle and high-side structure. This arrangement makes it easy for the glue spotting areas separated by the stabilizing strip 7 to be connected through the top of the stabilizing strip 7. When the LCD display body 1 is subsequently packaged with glue, the glue in different glue spotting areas can be flexibly diverted through the top of the stabilizing strip 7 to avoid the problem of local overflow of the sealing glue.
[0029] Among them, the stabilizing strip 7 and the glue blocking line 3 are both made of high-temperature resistant materials. The use of high-temperature resistant materials can avoid the impact of high temperature on the LCD display to a certain extent. In addition, the fading of the LCD sealing pen tip can be optimized and reduced by adjusting process technical parameters, such as PI curing temperature and liquid crystal perfusion parameters. The fading of the LCD sealing pen tip can also be reduced by optimizing materials, such as high-reliability liquid crystals and sealing glue. Among them, the curing temperature range of PI polyimide is generally between 200°C and 350°C. It should be noted that PI materials are susceptible to oxidation or decomposition under high temperature conditions. Therefore, the heating time and temperature need to be strictly controlled within the curing temperature range to avoid overheating or excessive exposure time leading to quality degradation.
[0030] It should be noted that although the "I"-shaped seal optimizes the problem of liquid crystal contamination and fading of the LCD sealing pen tip due to insufficient UV of the sealing glue when the LCD display is poured into the liquid crystal, the longer-sized separate glue blocking line 3 is easy to be skewed during installation. Therefore, when installing the longer-sized glue blocking line 3, if the operator's skill level is not high or the installation tool is not accurate enough, it may cause the glue blocking line 3 to be skewed during the installation process. The skewness of the glue blocking line 3 may cause uneven sealing, thereby affecting the sealing performance of the LCD display, which may cause liquid crystal leakage or external contaminants to enter the interior of the display, thereby affecting its display effect and service life. Therefore, the partition component set can allow the glue blocking line 3 to remain in a straight state during the installation process and prevent movement or skew.
[0031] Reference Figure 1 、 Figure 3 and Figure 4 In a preferred embodiment, the partition assembly includes two mounting bars 6, which are fixedly connected to the top outer wall of the display screen body 1. A mounting groove 10 is provided on the top outer wall of the mounting bar 6. A moving block 11 is provided inside the mounting groove 10. A limiting groove 14 is provided on one side outer wall of the moving block 11. A fixing groove 12 is provided on one side outer wall of the limiting groove 14. Three return springs 15 are provided on the inner wall of the fixing groove 12. A baffle 13 is provided at one end of the return spring 15. The top outer wall of the mounting bar 6 is connected to a fixing column 8 by a thread.
[0032] Among them, the top of the fixed column 8 is a "T"-shaped structure, and the length of the horizontal end of the T-shaped structure is equal to twice that of the vertical end. The T-shaped structure provides additional support area for the fixed column 8 by increasing the horizontal part of the top of the fixed column 8. This design enhances the stability of the fixed column 8, enabling it to withstand greater loads and external factors such as wind.
[0033] Specifically, when using, first press the baffle 13 continuously in the direction of the limit groove 14 with your fingers, thereby squeezing the three return springs 15 connected to the outer wall of one side of the baffle 13 and retracting it into the limit groove 14, and then place the movable block 11 in the installation groove 10. After it is completely placed in, release the squeezing on one side of the baffle 13. Under the elastic force of the return spring 15, the baffle 13 is pushed to a state flush with one side of the installation bar 6, and then tighten the four fixing columns 8, so that the fixing columns 8 limit the installation bar 6 downward while limiting the upper part of the rubber blocking line 3.
[0034] Reference Figure 3 and Figure 4, in a preferred embodiment, the fixing groove 12 has a "丄" - shaped structure, and the three return springs 15 are arranged in a triangular structure. Through the limitation of the "丄" - shaped structure, the accurate positioning of the fixed part in the vertical and horizontal directions can be ensured. The three return springs 15 are arranged in a triangular form, that is, the connection points between them form a triangle. This arrangement can ensure that the return springs 15 can evenly distribute stress when subjected to external forces, thereby improving their overall stability and service life.
[0035] Working principle: During use, the working element is installed in the assembly area 2, the glue - blocking line 3 is installed on the sealing area 9, and then the display screen body 1 is placed on the glue - applying platform. The limiting slot 5 in the glue - blocking line 3 is limited by the partition component, and the outer walls on both sides of the glue - blocking line 3 are limited by the two limiting plates 4. Then, the glue - applying device applies glue along the limiting slot 5 on the "工" - shaped glue - blocking line 3 set in this solution. The design principle of the "工" - shaped seal is to use the "工" - shaped structure to enhance the compressive performance of the box body, which can effectively disperse external forces and make the pressure evenly distributed, thereby improving the strength and stability of the seal. Especially in an environment with too high temperature and humidity, due to the stability of its structure, the "工" - shaped seal can better resist this deformation, thus protecting the liquid crystal layer and electronic components inside the LCD product from damage. And the design of the "工" - shaped seal usually has a closer contact surface, which can better prevent harmful substances such as external moisture and dust from invading the inside of the LCD product, thereby extending the service life of the LCD product and avoiding the problems of liquid crystal contamination during the liquid crystal perfusion of the display screen body 1 and the fading of the LCD sealing pen tip caused by insufficient UV of the sealing glue.

The substitution can be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present utility model and its inventive concept should be covered within the protection scope of the present utility model.
