Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and more specifically, to a protection structure for the stepped glass of a display screen. Background Art

[0002] Under the background of the rapid development of liquid crystal display technology, TFT (Thin Film Transistor) glass, as a key component of liquid crystal display screens, every detail in its design and manufacturing process is crucial. To meet the functional requirements of the display screen, especially during the process of bonding IC (Integrated Circuit) and FPC (Flexible Printed Circuit Board), the layout of TFT glass needs to be carefully designed. Usually, in order to effectively connect these key components, a large piece of glass is designed to protrude slightly more than the surrounding small pieces of glass, thus forming an obvious stepped structure.

[0003] However, while this stepped structure brings convenience in connection, it also brings significant mechanical challenges. Due to the height difference between the stepped part of the glass and other areas, its stress situation is more complex and it is more vulnerable to external environmental factors. Specifically, when the display screen is subjected to external forces such as dropping, vibration, or pressure during operation, the glass in the stepped part often becomes the area where stress is concentrated and is extremely prone to deformation. The accumulation of deformation over a long time, or an instant high-intensity impact, may cause the glass at the step to crack, thereby affecting the performance and lifespan of the entire display screen. Therefore, we make improvements on this and propose a protection structure for the stepped glass of a display screen. Summary of the Utility Model

[0004] The technical problem to be solved by the embodiments of the utility model is that the stepped part of the large piece of glass is prone to deformation due to external forces such as dropping, vibration, or pressure during operation, resulting in glass cracking.

[0006] A protection structure for the stepped glass of a display screen, comprising: a backlight rubber frame and a display screen assembly arranged in the backlight rubber frame. The display screen assembly includes a large piece of glass main body, and the large piece of glass main body has a step. First clearance grooves are opened on the inner walls of the backlight rubber frame near both sides of the step, and protective glue is filled in the first clearance grooves. By setting the first clearance grooves and filling protective glue in the first clearance grooves in this application, the stability of the stepped part of the large piece of glass main body is significantly enhanced, the deformation caused by external forces is effectively reduced, thereby reducing the risk of cracking of the large piece of glass main body; improving the durability and reliability of the display screen, extending its service life, reducing the repair and scrapping situations caused by the cracking of the large piece of glass main body, and reducing the production cost of the enterprise and the maintenance cost of users.

[0007] As an improved mode of the present utility model, the gap between the first clearance groove and the large glass body is 0.5 mm - 0.9 mm.

[0008] As an improved mode of the present utility model, the protective glue is RTV glue.

[0010] As an improved mode of the present utility model, a second clearance groove is further formed on the inner wall of the backlight glue holder, and the second clearance groove is located on the side of the large glass body away from the first clearance groove.

[0011] As an improved mode of the present utility model, the display screen assembly further includes a small glass body connected to the large glass body. A upper polarizer is connected to the side of the small glass body away from the large glass body, and a lower polarizer is connected to the side of the large glass body away from the small glass body.

[0012] As an improved mode of the present utility model, an FPC body is connected to the step of the large glass body, and the FPC body passes through the backlight glue holder.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs; the terms used in the description of the present application in the specification are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The mention of "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0024] As described in the background art, in order to effectively connect these key components, the large glass is designed to protrude slightly more than the surrounding small glass, thereby forming an obvious stepped structure; however, while this stepped structure brings convenience in connection, it also brings significant mechanical challenges. Due to the height difference between the stepped part of the glass and other areas, its stress situation is more complex and it is more vulnerable to external environmental factors. Specifically, when the display screen is subjected to external forces such as dropping, vibration, or pressure during operation, the glass in the stepped part often becomes the area where the stress is concentrated and is extremely prone to deformation. The accumulation of deformation over a long time, or an instant high-intensity impact, may cause the glass at the step to crack, thereby affecting the performance and lifespan of the entire display screen.

[0025] To solve this technical problem, the present utility model provides a display screen stepped glass protection structure.

[0026] Specifically, please refer to Figures 1-2 , the display screen step glass protection structure specifically includes:

[0027] A backlight rubber holder 1 and a display screen assembly 2 arranged inside the backlight rubber holder 1. The display screen assembly 2 includes a large glass body 201. The large glass body 201 has a step. First clearance grooves 3 are respectively formed on the inner walls of the backlight rubber holder 1 close to both sides of the step. A protective rubber 4 is filled in the first clearance grooves 3.

[0028] For the display screen step glass protection structure provided by the present utility model, by arranging the first clearance grooves 3 and filling the protective rubber 4 in the first clearance grooves 3, the stability of the step of the large glass body 201 is significantly enhanced, the deformation caused by external force is effectively reduced, thereby reducing the risk of breakage of the large glass body 201; the durability and reliability of the display screen are improved, its service life is extended, the repair and scrapping situations caused by the breakage of the large glass body 201 are reduced, and the production cost of the enterprise and the maintenance cost of the user are reduced.

[0029] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0031] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] Embodiment 1 of the display screen step glass protection structure of the present utility model

[0033] Please refer to Figures 1-2 , the display screen step glass protection structure of the present utility model includes: a backlight rubber holder 1 and a display screen assembly 2 arranged inside the backlight rubber holder 1. The display screen assembly 2 includes a large glass body 201. The large glass body 201 has a step. First clearance grooves 3 are respectively formed on the inner walls of the backlight rubber holder 1 close to both sides of the step. A protective rubber 4 is filled in the first clearance grooves 3. By arranging the first clearance grooves 3 and filling the protective rubber 4 in the first clearance grooves 3, the stability of the step of the large glass body 201 is significantly enhanced, the deformation caused by external force is effectively reduced, thereby reducing the risk of breakage of the large glass body 201; the durability and reliability of the display screen are improved, its service life is extended, the repair and scrapping situations caused by the breakage of the large glass body 201 are reduced, and the production cost of the enterprise and the maintenance cost of the user are reduced;

[0034] The combined design of the first clearance groove 3 and the protective rubber 4 provides a dedicated protection area at the step. The protective rubber 4 has certain elasticity and buffering performance. When an external force acts, the protective rubber 4 can absorb the impact force through its own deformation and disperse the external force over a larger area, thereby reducing the pressure on the step of the large glass body 201, and decreasing the possibility of deformation and rupture.

[0035] Furthermore, the gap between the first clearance groove 3 and the large glass body 201 is 0.5 mm - 0.9 mm. This specific gap range ensures the optimization of the filling effect of the protective rubber 4. On the one hand, the gap is not too small, enabling the protective rubber 4 to be fully filled and providing uniform support force for the step of the large glass body 201. On the other hand, the gap is not too large, avoiding the situation of insufficient filling of the protective rubber 4 resulting in poor protection effect. Such a design makes the protection structure more reasonable and effective, improving the overall stability and reliability of the display screen.

[0036] Furthermore, the protective rubber 4 is RTV glue. Using RTV glue for fixation not only enhances the firmness of the connection but also has certain elasticity, which can better absorb and disperse external force impacts and extend the service life of the display screen. The RTV glue enhances the firmness of the connection, ensuring that the connection between the large glass body 201 and the backlight glue holder 1 is more stable and reliable. Secondly, the elasticity of the RTV glue can quickly absorb and disperse the impact force when the display screen assembly 2 is subjected to external force impacts, reducing the damage to the large glass body 201. This elasticity can also adapt to different temperature and humidity changes, avoiding connection loosening or damage caused by environmental factors. In addition, extending the service life of the display screen assembly 2 means reducing the frequency of replacing the display screen, reducing resource consumption and environmental pollution.

[0037] Furthermore, the glue surface height of the protective rubber 4 is not higher than the frame wall height of the backlight glue holder 1, and the protective rubber 4 is used for gluing and fixing the step. Such a design ensures that the protective rubber 4 will not protrude to affect the installation of other components, ensuring the compactness and stability of the overall structure of the display screen. At the same time, the protective rubber 4 stably fixes the step, further enhancing the stability of the step of the large glass body 201, reducing the risk of damage caused by loosening or displacement. During the production and installation processes, it is also more convenient and fast, improving production efficiency.

[0038] Embodiment 2 of the display screen step glass protection structure of the present utility model

[0039] Furthermore, for the display screen step glass protection structure of the present utility model, as Figure 1As shown, a second clearance groove 5 is also formed on the inner wall of the backlight adhesive holder 1. The second clearance groove 5 is located on the side of the large glass body 201 away from the first clearance groove 3. The provision of the second clearance groove 5 can reduce the contact between the corners on the side of the large glass body 201 away from the first clearance groove 3 and the inner wall of the backlight adhesive holder 1, and reduce the damage of the corners of the large glass body 201. During transportation, installation and use, the corners of the large glass body 201 are easily collided and squeezed. The existence of the second clearance groove 5 reduces the possibility of such contact and reduces the risk of corner damage. This not only improves the appearance quality of the display screen, but also ensures the stability of its display performance. At the same time, reducing corner damage also extends the service life of the display screen and reduces the maintenance cost.

[0040] Further, as Figure 3 shown, the display screen assembly 2 further includes a small glass body 202 connected to the large glass body 201. A polarizer 203 is connected to the side of the small glass body 202 away from the large glass body 201, and a polarizer 204 is connected to the side of the large glass body 201 away from the small glass body 202. The cooperation of components such as the small glass body 202, the polarizer 203 and the polarizer 204 can optimize the optical characteristics of the display screen. They each play different roles and jointly provide users with clear and vivid image display. During the design process, the interaction and influence of these components are fully considered to achieve the best display effect.

[0041] Embodiment III of the stepped glass protection structure of the display screen of the present utility model

[0042] Further, as Figures 1-2 shown, an FPC body 205 is connected to the step of the large glass body 201, and the FPC body 205 passes through the backlight adhesive holder 1; the connection of the FPC body 1 realizes the effective connection between the display screen assembly 2 and the external circuit, ensuring the stable transmission of signals and the normal operation of the display screen assembly 2. This design enables the display screen assembly 2 to interact with various external devices, expanding the application range of the display screen assembly 2. At the same time, the flexibility and bendability of the FPC body 205 also provide greater flexibility for the design and installation of the display screen assembly 2; as a flexible circuit board, the FPC has the characteristics of being thin, light and bendable, and is very suitable for connecting the complex circuits inside the display screen assembly 2 and external devices.

[0043] Further, as Figures 1-2 shown, an avoidance opening 101 is formed on the backlight adhesive holder 1, and the avoidance opening 101 is for the FPC body 205 to pass through.

[0044] Further, as Figures 1-3As shown, an FPC connector 206 is connected to the FPC body 205. The presence of the FPC connector 206 enables the display screen assembly 2 to be conveniently connected to and disconnected from external devices, improving the usability and versatility of the display screen assembly 2.

[0045] Furthermore, as Figure 4 shown, an FPC reinforcement plate 207 is also connected to the FPC body 205. The FPC reinforcement plate 207 and the FPC connector 206 are respectively located on both sides of the FPC body 205. The FPC reinforcement plate 207 reinforces the FPC body 205 to facilitate the insertion and extraction of the FPC connector 206.

[0046] During use, after the display screen assembly 2 is installed inside the backlight rubber holder 1, a protective glue 4 is filled between the first clearance groove 3 and the large glass body 201. The setting of the protective glue 4 significantly enhances the stability of the stepped portion of the large glass body 201, effectively reducing the deformation caused by external forces, thereby reducing the risk of breakage of the large glass body 201.
