Description

Technical Field

[0001] This utility model relates to the field of liquid crystal module technology, specifically to a liquid crystal module with light transmission effect. Background Technology

[0002] In the pursuit of display quality and performance, all display products, including monitors and televisions, are constantly striving for improved aesthetics. Aesthetically pleasing designs, low cost, and ease of maintenance have become ongoing research topics. The extruded bezel of a liquid crystal display module is a crucial component, primarily used to support, fix, and protect the internal liquid crystal panel, backlight module, and circuit components. Manufactured using an extrusion molding process, it features high precision, low cost, and high efficiency.

[0003] Combined with appendix Figure 1 As shown, existing LCD modules generally use a single backplate, i.e., the back cover, as the main structure. For the top side, it uses a patch for fixation, which cannot achieve rapid assembly and snap-fit, resulting in low installation efficiency and high cost. The ground side uses a plastic frame and a plastic light guide plate, meaning the backlight material can only be assembled layered from inside the machine, failing to achieve the effect of displaying a logo through light. Furthermore, the fixing structure on the back of existing LCD modules generally uses a side-grooved sliding rail for wall mounting, lacking buffer space during installation. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a liquid crystal module with light transmission effect, so as to achieve the purpose of having light transmission effect and being easy to assemble.

[0005] This utility model provides a liquid crystal module with light transmission effect, including a top end and a bottom end. The liquid crystal module, from front to back, includes a liquid crystal panel, a film, a glass light guide plate, reflective paper, a metal back plate, and a glass back plate; it also includes a light strip at one end; the liquid crystal panel is located on the outermost layer of the front end. The metal back plate is bent from the back end to the front end at the bottom end to form a semi-enclosed space, within which the light strip is located. The metal back plate serves a dual function as a heat sink and a supporting frame, and the semi-enclosed space facilitates the protection and heat dissipation of the light strip. The top end has an extruded frame for fixing the side of the liquid crystal module; the metal back plate has a light-transmitting hole, and a logo is printed on the glass back plate opposite the light-transmitting hole.

[0006] Preferably, the light-transmitting hole is located on one side of the central axis of the liquid crystal module.

[0007] Furthermore, the extruded frame includes a first embedding portion and a second embedding portion, wherein the first embedding portion is embedded between the liquid crystal panel and the film; and the second embedding portion is embedded between the iron back plate and the glass back plate.

[0008] This utility model uses an extruded frame to snap together an iron backplate and a glass light guide plate, and then attaches a glass backplate with a screen-printed translucent logo to serve as the backlight for a television or monitor. Glass is used as the main structure of the light guide plate, which wraps around the iron backplate and the diaphragm. The entire structure is then snapped into a slot formed by the first and second inserts of the extruded frame, and finally, the glass backplate is attached. This design results in low overall product cost, high production efficiency, a beautiful appearance, and ultra-thin thickness. The modular and standardized backlight module design further reduces development and manufacturing costs.

[0009] More preferably, the second embedding part is U-shaped. Since the installation structures of the top and bottom ends are different, the distances between different structural components are also different. Therefore, the U-shaped design of the second embedding part can achieve two advantages: first, it can achieve compact installation of the iron back panel and the glass back panel; second, since the extruded frame has a certain resilience, its U-shaped structure has more buffer space during installation, making the overall structure more stable.

[0010] Furthermore, a first double-sided foam adhesive is provided between the liquid crystal panel and the first embedded part. The first double-sided foam adhesive serves to fix the liquid crystal panel and the first embedded part, while preventing friction between the two from causing wear on the components.

[0011] Preferably, a first double-sided adhesive is provided between the glass back panel and the second embedded part. The first double-sided adhesive also serves to stick and fix the parts, and both the first double-sided foam adhesive and the first double-sided adhesive are relatively short, serving a dual purpose of adhesion and cushioning to prevent wear.

[0012] Preferably, the liquid crystal module further includes a front frame for fixing the ground side end. The front frame is F-shaped and includes a first baffle and a second baffle. The first baffle is used to fix the liquid crystal panel, and the second baffle is used to engage the glass back panel. A second double-sided adhesive is also provided between the second baffle and the glass back panel.

[0013] The ground side of this utility model is fixed by a front frame. The first and second baffles have similar functions to the first and second embedded parts, mainly serving to fix the parts and facilitate assembly.

[0014] Furthermore, the end point of the iron backplate, bent from the back to the front at the ground side, is located between the liquid crystal panel and the glass light guide plate; and the surface of the end point is horizontal to the film and does not abut against it; the liquid crystal module is also provided with a second double-sided foam adhesive, one side of which is attached to the inner side of the liquid crystal panel, and the other side is attached to the end point and the outer side of the film. The iron backplate is bent from the back to the front, and is specifically designed according to the shape of the light strip. The end point of the iron backplate extends between the glass light guide plate and the liquid crystal panel, and the film is also located between the two. The plane of the end point of the iron backplate is the same as the plane of the film. There is a small gap between the end point and the ground side end of the film, and the two do not contact each other. The liquid crystal panel is fixed by the second double-sided foam adhesive, which also fixes the end point of the film and the iron backplate.

[0015] Furthermore, the liquid crystal module of this utility model also includes a fixing component disposed on the outside of the glass back plate. The fixing component includes a fixing plate, a torsion spring, a rotating shaft, a U-shaped pin, and a fixing frame. The fixing plate is fixed to the glass back plate by screws. The two ends of the rotating shaft pass through the torsion spring, the U-shaped pin, and the fixing plate respectively. One end of the torsion spring is connected to the fixing plate, and the other end is connected to the U-shaped pin. The fixing frame is attached to the outside of the fixing plate.

[0016] The difference between this invention and existing technologies lies in the installation of a fixing component on the glass back panel. This fixing component utilizes the rebound and cushioning effect of a torsion spring at one end, resulting in higher stability during installation. The fixing plate is fixed to the glass back panel with screws; both ends of the rotating shaft pass sequentially through a set of torsion springs, one end of a U-shaped pin, and a bearing, and are finally fixed to the fixing plate with bolts. The U-shaped pin and the rotating shaft are movably connected; utilizing the rebound effect of the torsion springs, the U-shaped pin can rotate and return to its original position relative to the rotating shaft, providing a cushioning effect during installation. The fixing frame serves to protect the internal components and enhances aesthetics; its two ends are fixed to the fixing plate with screws.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention designs a novel backlight structure that uses an extruded frame to engage a metal backplate and a glass light guide plate, followed by bonding the glass backplate. The main structure comprises a glass light guide plate, a glass backplate, and a liquid crystal panel. The glass backplate features a translucent logo as its exterior element. The extruded frame uses slots to engage the metal backplate, glass light guide plate, and film, and then the liquid crystal panel is bonded to the extruded frame. This design changes the existing backlighting method, eliminating the need for screws and clips, saving materials and processes, and enabling a universal backlight product form applicable to all edge-lit backlight modules in display product design. Furthermore, this invention incorporates a buffering fixing component, resulting in higher overall stability. Attached Figure Description

[0029] Example

[0030] This embodiment protects a liquid crystal module with light-transmitting properties, such as... Figure 2 and 3 As shown, the liquid crystal module includes a top end 100 and a bottom end 200. From front to back, the liquid crystal module includes a liquid crystal panel 1, a film 2, a glass light guide plate 3, reflective paper 4, a metal back plate 5, and a glass back plate 6. It also includes a light strip 7 at one end. The liquid crystal panel 1 is located on the outermost layer of the front. The metal back plate 5 is bent from the back to the front at the bottom end 200 to form a semi-enclosed space 10, in which the light strip 7 is located. The metal back plate 5 serves as both a heat sink and a supporting frame, and the semi-enclosed space 10 facilitates the protection and heat dissipation of the light strip 7. The top end 100 has an extruded frame 8 for fixing the side of the liquid crystal module. The metal back plate 5 has a light-transmitting hole 20 located on one side of the central axis of the liquid crystal module. The glass back plate 6 has a logo printed on it, facing the light-transmitting hole 20.

[0031] Combination Figure 4As shown, the extruded frame 8 includes a first embedding part 81 and a second embedding part 82. The first embedding part 81 is embedded between the liquid crystal panel 1 and the film 2; the second embedding part 82 is embedded between the iron back plate 5 and the glass back plate 6. The second embedding part 82 is U-shaped. The U-shaped design of the second embedding part 82 enables a compact installation of the iron back plate 5 and the glass back plate 6. Furthermore, due to the certain resilience of the extruded frame 8, its U-shaped structure provides more buffer space during installation, making the overall structure more stable. A first double-sided foam adhesive 30 is provided between the liquid crystal panel 1 and the first embedding part 81. A first double-sided adhesive 40 is provided between the glass back plate 6 and the second embedding part 82. Both the first double-sided foam adhesive 30 and the first double-sided adhesive 40 are relatively short, serving a dual purpose of adhesion and buffering to prevent wear. Figure 3 As shown, the liquid crystal module also includes a front frame 9 for fixing the ground side end 200. The front frame 9 is F-shaped and includes a first baffle 91 and a second baffle 92. The first baffle 91 is used to fix the liquid crystal panel 1, and the second baffle 92 is used to engage the glass back plate 6. A second double-sided adhesive 50 is also provided between the second baffle 92 and the glass back plate 6. The end point 51 of the iron back plate 5, which is bent from the back to the front at the ground side end 200, is located between the liquid crystal panel 1 and the glass light guide plate 3; and the surface where the end point 51 is located is horizontal to the film 2 and does not abut against it. The liquid crystal module also has a second double-sided foam adhesive 60, one side of which is attached to the inner side of the liquid crystal panel 1, and the other side is attached to the end point 51 and the outer side of the film 2. There is a small gap between endpoint 51 and ground end 200 of diaphragm 2, and the two do not contact each other. The liquid crystal panel 1 is fixed by the second double-sided foam adhesive 60, which also fixes the endpoint 51 of diaphragm 2 and iron back plate 5.

[0032] like Figure 5 As shown, the liquid crystal module also includes a fixing component 70 disposed on the outside of the glass back plate 6, combined with Figures 6-7 As shown, the fixing assembly 70 includes a fixing plate 701, a torsion spring 702, a rotating shaft 703, a U-shaped pin 704, and a fixing frame 705; the fixing plate 701 is fixed to the glass back panel 6 by screws; the two ends of the rotating shaft 703 pass through the torsion spring 702, the U-shaped pin 704, and the fixing plate 701 respectively; one end of the torsion spring 702 is connected to the fixing plate 701, and the other end is connected to the U-shaped pin 704; the fixing frame 705 is attached to the outside of the fixing plate 701.

[0033] This utility model enables the original display product to be equipped with... Figure 1The original backlight design, consisting of a metal backplate 5, fixing components, light strips 7, reflective paper 4, glass light guide plate 3, diaphragm 2 series, middle frame, and LCD panel 1, is replaced with a glass backplate 6, extruded frame 8, metal backplate 5, reflective paper 4, glass light guide plate 3, diaphragm 2, and LCD panel 1. This achieves an ultra-thin, low-cost, and easily automated backlight display design. This invention eliminates the need for screws and clips in traditional side-lit backlight displays; the extruded frame 8 is used for the backlight structure. Currently, existing backlight modules use a single backplate or back shell as the main structure, requiring backlight materials to be layered and assembled from within the machine, resulting in relatively weak overall strength. This design uses a glass light guide plate 3 and a glass backplate 6 as the main structure, wrapping the metal backplate 5 and diaphragm 2 before being snapped into place within the groove of the extruded frame 8. The glass backplate 6 and LCD panel 1 are then attached, resulting in an ultra-thin overall structure. The glass backplate 6 features a translucent logo, achieving low cost, a beautiful appearance, and ease of automated production.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the preferred embodiments above, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model should not depart from the spirit and scope of this utility model. Those skilled in the art can also make other changes within the spirit of this utility model for its design, as long as they do not deviate from the technical effect of this utility model. These changes made according to the spirit of this utility model should all be included within the scope of protection claimed by this utility model.
