[0038] As described in the background section, existing displays are assembled by first mounting tempered glass on the front frame, then fixing an optical film between the middle frame and the back panel, followed by placing the liquid crystal panel on the front of the middle frame and pressing it together with the front frame. However, the presence of the middle frame results in a relatively thick overall display.

[0039] Referring to Figures 1 to 4, in order to solve the above-mentioned problems, according to one aspect of this application, an embodiment of this application provides a display screen, the display screen including a front frame 100 and a back panel 200, the back panel 200 being connected to the front frame 100 and enclosing an installation space 110; the display screen also includes a cover glass 300, a liquid crystal panel 400 and an optical film 500 sequentially disposed in the installation space 110 along a preset direction, the cover glass 300 being mounted on the front frame 100, the liquid crystal panel 400 being connected to the cover glass 300 through a first connection structure 600, and the optical film 500 being mounted on the back panel 200.

[0040] In this embodiment, the display screen can be a television screen, an interactive display, or an educational device screen, depending on the actual needs, and is not limited in detail here. The front frame 100 is made of aluminum profile. In other embodiments, the front frame 100 can also be made of profiles or frames made of other materials. The back plate 200 is connected to the front frame 100 using connecting screws. The mounting space 110 is provided on the surface of the front frame 100 near the back plate 200. The mounting space 110 has a mounting opening, through which the cover glass 300 is mounted on the front frame 100. The cover glass 300 is tempered glass. In other embodiments, the cover glass 300 can also be different types of glass such as anti-reflective glass, smart glass, or UV-resistant glass. The liquid crystal panel 400 is located on the side of the cover glass 300 near the back plate 200. The first connecting structure 600 may be two cooperating magnetic blocks, one of which is fixedly mounted on the surface of the liquid crystal panel 400 near the cover glass 300, and the other is fixedly mounted on the surface of the cover glass 300 near the liquid crystal panel 400. In other embodiments, the first connecting structure 600 may also be a pin, wherein both the cover glass 300 and the liquid crystal panel 400 are provided with insertion holes for the pin. The optical film 500 is located on the side of the liquid crystal panel 400 near the back plate 200.

[0041] During assembly, the display screen of this application first connects the liquid crystal panel 400 and the cover glass 300 using a first connecting structure 600. Then, the cover glass 300 with the liquid crystal panel 400 is mounted on the front frame 100, and the optical film 500 is mounted on the back plate 200. Next, the back plate 200 is connected to the front frame 100. At this point, the cover glass 300, liquid crystal panel 400, and optical film 500 are sequentially arranged in the mounting space 110 along a predetermined direction. This design not only helps to reduce the overall thickness and volume of the display screen, improving its product quality, but also effectively protects the cover glass 300, liquid crystal panel 400, and optical film 500, thereby extending their service life. Furthermore, this design reduces the number of components in the display screen, lowers its structural complexity, effectively reduces assembly difficulty and cost, and improves assembly efficiency. The first connection structure 600 enables the LCD panel 400 to be mounted on the front frame 100, enhancing the stability of the LCD panel 400 within the mounting space 110.

[0042] Referring to Figures 3 and 4, in one embodiment, the first connecting structure 600 is bonded to the cover glass 300 and to the liquid crystal panel 400.

[0043] In this embodiment, the first connecting structure 600 can be any adhesive component such as double-sided tape, double-sided tape strip, or glue. The first connecting structure 600 not only enables a stable connection between the liquid crystal panel 400 and the cover glass 300, but also fills the gap between them, reducing the entry of external dust, moisture, or other contaminants, thereby extending the lifespan of the display screen. Furthermore, this design helps simplify the assembly process, improve assembly efficiency, and reduce the structural complexity and weight of the display screen.

[0044] Referring to Figures 3 and 4, in one embodiment, the first connecting structure 600 is a double-sided adhesive strip. In this embodiment, the thickness of the double-sided adhesive strip ranges from 0.2 mm to 2 mm, and in one specific embodiment, the thickness of the double-sided adhesive strip is 1 mm. Of course, in other embodiments, the thickness of the double-sided adhesive strip can be determined according to actual needs.

[0045] The double-sided adhesive strip not only ensures a stable connection between the LCD panel 400 and the cover glass 300, but also effectively fills the gap between them, reducing the entry of external dust, moisture, or other contaminants. Furthermore, due to the elasticity of the double-sided adhesive strip, it can adapt to temperature changes and minor material displacements, thereby extending the lifespan of the connection.

[0046] Referring to Figures 3 and 4, in one embodiment, a cover glass 300 covers a liquid crystal panel 400, and a first connecting structure 600 is arranged along the circumference of the liquid crystal panel 400.

[0047] In this embodiment, the first connecting structure 600 is a ring structure with its ends connected. This design not only helps to make the display screen thinner and lighter, but also helps to reduce costs. Furthermore, this design effectively fills the gap between the liquid crystal panel 400 and the cover glass 300, preventing external dust, moisture, or other contaminants from entering the gap, thereby enhancing the durability and reliability of the display screen.

[0048] Referring to Figure 3, in one embodiment, the liquid crystal panel 400 is bonded to the optical film 500. This design not only helps reduce light reflection and refraction, improving optical performance and thus enhancing the display brightness and clarity, but also effectively prevents relative movement between the liquid crystal panel 400 and the optical film 500 through close bonding. This keeps them relatively stationary, reducing the risk of mutual scratches caused by vibration. Furthermore, this design effectively reduces the gap between the liquid crystal panel 400 and the optical film 500, lowering glare, reflection, and optical distortion. This not only improves the user's visual experience under different lighting conditions but also enhances the realism of the image.

[0049] Referring to Figures 2 and 3, in one embodiment, a first clamping member 700 and a second clamping member 800 are installed on the front frame 100 at intervals along a preset direction. A clamping area is formed between the first clamping member 700 and the second clamping member 800, and the cover glass 300 is installed within the clamping area. The first clamping member 700 applies a clamping force toward the second clamping member 800 to the cover glass 300 by contacting it, and the second clamping member 800 applies a clamping force toward the first clamping member 700 to the cover glass 300 by contacting it.

[0050] In this embodiment, the first clamping member 700 is an infrared filter strip, located on the side of the second clamping member 800 near the front frame 100. The front frame 100 is provided with a mounting groove 120, which communicates with the mounting space 110. The infrared filter strip is fixedly installed in the mounting groove 120. In other embodiments, the first clamping member 700 may also be other clamping components capable of applying clamping force to the cover glass 300. The first clamping member 700 contacts the first surface of the cover glass 300; the second clamping member 800 contacts the second surface of the cover glass 300, and the first surface and the second surface of the cover glass 300 are disposed opposite to each other.

[0051] By employing the first clamping member 700 and the second clamping member 800 used in this application, not only can a bidirectional clamping force be applied to the cover glass 300, thereby enhancing the stability of the cover glass 300 within the installation space 110 and improving the durability and service life of the connection, but it can also effectively reduce local stress concentration and decrease the risk of the cover glass 300 breaking. Furthermore, to ensure uniform distribution of the clamping force, both the first clamping member 700 and the second clamping member 800 are kept in contact with the cover glass 300.

[0052] Referring to Figures 2, 3, and 5, in one embodiment, the second clamping member 800 is located on the side of the first clamping member 700 near the back plate 200; the second clamping member 800 includes a clamping portion 810 and a mounting portion 820, the clamping portion 810 applies a clamping force toward the cover glass 300 by contacting the cover glass 300; the mounting portion 820 is located on the side of the clamping portion 810 away from the first clamping member 700 and is connected to the clamping portion 810, and the mounting portion 820 is detachably mounted on the front frame 100.

[0053] In this embodiment, the mounting portion 820 and the clamping portion 810 are an integral structure; the mounting portion 820 can be detachably mounted on the front frame 100 using a plug-in, snap-fit, or magnetic method. The detachable mounting of the mounting portion 820 on the front frame 100 not only makes the installation and removal of the second clamping member 800 more convenient, simplifying the assembly and maintenance process, but also allows the mounting position of the second clamping member 800 on the front frame 100 to be adjusted as needed, improving installation flexibility and enabling the second clamping member 800 to better adapt to different design requirements. Furthermore, to ensure uniform distribution of clamping force, the clamping portion 810 remains in contact with the cover glass 300.

[0054] Referring to FIG3, in one embodiment, the second clamping member 800 further includes a connecting portion 830, the clamping portion 810 and the mounting portion 820 are connected through the connecting portion 830, and the connecting portion 830 contacts the groove wall of the mounting space 110.

[0055] In this embodiment, the clamping portion 810, the connecting portion 830, and the mounting portion 820 are integrated into a single structure. To facilitate the manufacturing and processing of the second clamping member 800 and to ensure the structural strength of the second clamping member 800 itself, the length direction of the clamping portion 810 is perpendicular to the length direction of the connecting portion 830, and the length direction of the connecting portion 830 is perpendicular to the length direction of the mounting portion 820. The connecting portion 830 not only serves a connecting function but also strengthens the structural strength of the second clamping member 800. Furthermore, to further enhance the stability of the second clamping member 800 within the mounting space 110, the connecting portion 830 remains in close contact with the groove wall of the mounting space 110.

[0056] Referring to Figures 3 and 5, in one embodiment, the mounting portion 820 is detachably mounted on the front frame 100 via a connecting member 900. In this embodiment, the connecting member 900 is a headed fastening screw, the mounting portion 820 has a through hole for the fastening screw to pass through, and the surface of the front frame 100 near the back plate 200 has a threaded hole for the fastening screw to engage with its threads. In other embodiments, the connecting member 900 may also be a fastening pin or a fastening screw.

[0057] Referring to Figure 5, in one embodiment, there are multiple second clamping members 800, which are spaced apart. The multiple second clamping members 800 help improve the stability of the cover glass 300 within the installation space 110.

[0058] Referring to Figures 3, 6 and 7, in one embodiment, a limiting structure 1000 is installed on the back plate 200. The limiting structure 1000 contacts two adjacent sides of the optical film 500 to prevent the optical film 500 from shaking on the back plate 200.

[0059] In this embodiment, the limiting structure 1000 is an L-shaped plastic or metal clip, which is detachably mounted on the back plate 200 using connecting screws. In other embodiments, the limiting structure 1000 can also be mounted on the back plate 200 using a snap-fit ​​or plug-in method. The limiting structure 1000 serves to restrict the swaying of the optical film 500 on the back plate 200, effectively improving the stability of the optical film 500 on the back plate 200. Furthermore, to strengthen the limiting effect, four limiting structures 1000 are used, each corresponding to one of the four corners of the optical film 500.

[0060] Referring to Figures 3, 6, and 7, in one embodiment, the display screen further includes a diffuser plate 1100. The diffuser plate 1100 is located on the side of the optical film 500 away from the liquid crystal panel 400. The diffuser plate 1100 is connected to the optical film 500 through a second connecting structure, and the diffuser plate 1100 is mounted on the back plate 200 through a third connecting structure. The limiting structure 1000 contacts two adjacent sides of the diffuser plate 1100 and can prevent the diffuser plate 1100 from shaking on the back plate 200.

[0061] In this embodiment, the direction from the diffuser plate 1100 to the optical film 500 is parallel to a preset direction. The second connection structure can be two cooperating magnetic blocks, one of which is fixedly installed on the surface of the diffuser plate 1100 near the optical film 500, and the other is fixedly installed on the surface of the optical film 500 near the diffuser plate 1100; in other embodiments, the second connection structure can also be a pin, wherein both the optical film 500 and the diffuser plate 1100 are provided with insertion holes for the pin. The third connection structure can be two cooperating magnetic blocks, one of which is fixedly installed on the surface of the back plate 200 near the diffuser plate 1100, and the other is fixedly installed on the surface of the diffuser plate 1100 near the back plate 200; in other embodiments, the third connection structure can also be a pin, wherein both the diffuser plate 1100 and the back plate 200 are provided with insertion holes for the pin.

[0062] The diffuser plate 1100 not only serves as a connector, allowing the optical film 500 to be securely mounted on the back plate 200, but also distributes light evenly, reducing glare and improving color performance. The limiting structure 1000 restricts the movement of the diffuser plate 1100 on the back plate 200, enhancing the stability of the diffuser plate 1100 on the back plate 200.

[0063] Referring to FIG3, in one embodiment, the mounting space 110 has a mounting opening, the back plate 200 has a mounting surface 210 covering the mounting opening, and the diffuser plate 1100 is mounted on the mounting surface 210 via a third connecting structure.

[0064] In this embodiment, the mounting surface 210 completely covers the mounting opening, while maintaining contact with the surface of the front frame 100 near the back panel 200. This design, where the mounting surface 210 covers the mounting opening, effectively fills the gap between the mounting opening and the mounting surface 210, preventing dust, moisture, or other contaminants from the external environment from entering the mounting space 110, thereby improving the durability and lifespan of the components within the mounting space 110. It also eliminates exposed mounting openings, enhancing the overall aesthetics of the display screen. Furthermore, a limiting structure 1000 is mounted on the mounting surface 210 to ensure a limiting effect.

[0065] Referring to FIG3, in one embodiment, the second connecting structure is bonded to the optical film 500 and to the diffuser plate 1100.

[0066] In this embodiment, the second connecting structure can be any transparent adhesive component such as transparent double-sided tape or transparent glue. The provided second connecting structure not only enables a stable connection between the optical film 500 and the diffuser plate 1100, but also fills the gap between them, reducing the entry of external dust, moisture, or other contaminants into this gap, thereby extending the lifespan of the display screen. Furthermore, this design helps simplify the assembly process, improve assembly efficiency, and reduce the structural complexity and weight of the display screen.

[0067] Referring to FIG3, in one embodiment, the third connecting structure is bonded to the diffuser plate 1100 and to the mounting surface 210.

[0068] In this embodiment, the third connection structure can be any transparent adhesive component such as transparent double-sided tape or transparent glue. This third connection structure not only enables a stable connection between the diffuser plate 1100 and the mounting surface 210, but also fills the gap between them, reducing the entry of external dust, moisture, or other contaminants, thereby extending the lifespan of the display screen. Furthermore, this design helps simplify the assembly process, improve assembly efficiency, and reduce the structural complexity and weight of the display screen.

[0069] Referring to Figures 1 to 7, during the assembly of the display screen of this application, the optical film 500, the diffuser plate 1100, and the back plate 200 are first assembled.
