Technical Field

[0001] This utility model relates to the field of display technology, and in particular to an ultra-narrow bezel backlight structure for an integrated frameless display screen. Background Technology

[0002] Display screens are widely used electronic display devices, such as in automotive and other applications, instruments, mobile phones, computers, televisions, billboards, industrial control systems, medical equipment, and aerospace, allowing us to clearly see images and text and conveying various information. With the development of the display industry, electronification, new energy sources, lightweighting, multi-screen technology, ultra-thin and ultra-narrow bezel designs, and borderless designs have become new trends. In particular, the demand for LCD screens is increasing, leading to a greater need for lightweight structures and ultra-thin and ultra-narrow bezel designs.

[0003] With the rapid development of the display industry, the requirements for display screen thickness are getting thinner and thinner, and the requirements for bezels are getting narrower and narrower. There are even ideas of floating bezel-less displays. The thinner and narrower the product, the more space is saved for the display screen. The demand for thin, light and ultra-narrow bezel displays has increased significantly in various fields. Summary of the Invention

[0004] To address the technical challenges of ultra-narrow bezel backlight structures in borderless displays, this invention provides an ultra-narrow bezel backlight structure for borderless displays. The borderless design realizes the concept of a borderless display. Optimized internal backlight design achieves an extremely narrow bezel, simultaneously reducing the risk of light leakage around the edges. The integrated die-cast backplate design allows for an extremely thin profile, resulting in a more aesthetically pleasing appearance, simplified manufacturing processes, and cost reduction.

[0005] The present invention solves its technical problem by adopting the following technical solution: An ultra-narrow bezel backlight structure for an integrated frameless display mainly includes an integrated die-cast backplate, backlight optical components, and sheet metal.

[0006] The back of the integrated die-cast back panel is the exterior surface of the display screen. The back is designed with vehicle mounting feet, which are integrated into the integrated die-cast back panel and formed by a mold.

[0007] The integrated die-cast back panel is designed with structural adhesive dots and surfaces for bonding the display screen, a hidden sheet metal hanging ear groove structure, and a raised dot structure around its perimeter. The structural adhesive dots and surfaces, the hidden sheet metal hanging ear groove structure, and the raised dot structure are part of the design of the integrated die-cast back panel and are integrally formed by the mold.

[0008] The lower side of the integrated die-cast backplate features a recessed structure for the backlight optical component mounting ears and a flexible flat cable insertion hole structure. The mounting ear recessed structure and the flexible flat cable insertion hole structure are part of the design of the lower side of the integrated die-cast backplate and are integrally formed by the mold.

[0009] The integrated die-cast back panel eliminates the conventional perimeter retaining wall structure and incorporates a micro-structure designed to prevent glue spillage. This micro-structure is a partial design feature on the lower side of the integrated die-cast back panel and is integrally molded.

[0010] Furthermore, the backlight optical components are assembled and fixed within the receiving cavity of the integrated die-cast backplate using a conventional structure.

[0011] Furthermore, the sheet metal is partially designed with hanging ear structures around its perimeter.

[0012] Furthermore, the middle sheet metal eliminates the conventional side wall retaining structure, and the middle sheet metal is assembled on an integrated die-cast back plate through a hanging ear structure and a conventional buckle structure to form the backlight assembly of the display screen.

[0013] Furthermore, the backlight optical components are then bonded to the display screen using structural adhesive dots around the integrated die-cast backplate, becoming the backlight part of electronic display devices.

[0014] Furthermore, the backlight assembly is connected to the main unit using automotive or other application mounting feet on the back of the integrated die-cast backplate.

[0015] Compared with the existing technology, the technical advantages and beneficial effects of this utility model are as follows: The integrated frameless display screen of this utility model features an ultra-narrow bezel backlight structure. The integrated die-cast back panel adopts a frameless design, and the screen is bonded to the adhesive surface of the integrated die-cast back panel with structural adhesive. The appearance realizes the concept of a frameless display screen. The integrated die-cast back panel also integrates the design of the exterior back shell and mounting foot structure, achieving an extremely thin thickness, a more beautiful appearance, simplified production process, and cost reduction.

[0016] The concealed mounting bracket structure with partial design around the central sheet metal eliminates the need for the conventional stepped structure supporting the central sheet metal on the unibody die-cast backplate. This increases the expansion and contraction space for the backlight optical components, reducing the risk of light leakage around them. The central sheet metal design also eliminates the conventional sidewall structure, reducing the thickness of the sheet metal and allowing for a narrower bezel. The backlight bezel width can be designed to be almost as wide as the black border of the LCD glass, and the adhesive bonding width of the display screen can be minimized, achieving the goal of minimizing the bezel width around the non-display areas of the display device and fulfilling the design requirements for an ultra-narrow bezel backlight structure in an integrated borderless display.

[0027] The technical structural solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the structure of this utility model, and not all embodiments. The additional technical features and advantages of this utility model will become more apparent in the following description, or can be learned through specific practice of this utility model. Example

[0028] like Figure 1 and Figure 2 As shown, this utility model mainly consists of three main components, and the direct positions, connections, and functions of each component are as follows: The backlight optical component 2 is assembled and fixed in the receiving cavity of the one-piece die-cast backplate 1 by conventional adhesive and limiting structures designed around the one-piece die-cast backplate 1.

[0029] The film material hanger 2-1 of the backlight optical component 2 is assembled in the film material hanger groove structure 1-1 on the lower side of the integrated die-cast back plate 1.

[0030] The hanging ears 3-1 of the middle sheet metal 3 are assembled in the hidden middle sheet metal hanging ear recessed structure 1-2 of the integrated die-cast back plate 1. The side wall without retaining wall structure 3-2 of the middle sheet metal 3 plays the role of reducing the width of the frame. The conventionally designed snap-fit ​​structure around the integrated die-cast back plate 1 and the middle sheet metal 3 are assembled together to form a backlight component.

[0031] The backlight assembly utilizes the adhesive application surfaces 1-3 around the integrated die-cast backplate 1 to bond the display screen into various applications, becoming the backlight part of electronic display devices. During the adhesive application process, the raised dot structures 1-4 around the integrated die-cast backplate 1 control the thickness of the structural adhesive. The retaining wall microstructures 1-5 around the integrated die-cast backplate 1 prevent adhesive overflow. The flexible flat cable of the display screen is seamlessly connected and aesthetically pleasing through the through holes 1-6 on the lower side of the integrated die-cast backplate 1. The display screen is suspended and bonded to the integrated die-cast backplate 1 with structural adhesive, achieving the concept of a borderless display screen.

[0032] The backlight assembly is connected to the whole machine via the automotive or other application mounting feet structure 1-7 on the back of the integrated die-cast backplate 1.

[0033] The appearance surfaces 1-8 on the back of the integrated die-cast back panel 1 are directly displayed as the appearance surfaces of the electronic display device.

[0034] refer to Figure 3 , Figure 4 and Figure 5 The assembly process of this utility model embodiment is as follows: The backlight optical component 2 is assembled and fixed in the receiving cavity of the one-piece die-cast backplate 1 by conventional adhesive and limiting structures designed around the one-piece die-cast backplate 1.

[0035] The film material hook 2-1 of the backlight optical component 2 is assembled in the hook groove structure 1-1 on the lower side of the integrated die-cast back plate 1.

[0036] The hanging ears 3-1 of the middle sheet metal 3 are assembled in the hidden hanging ear recess structure 1-2 of the one-piece die-cast back plate 1; the one-piece die-cast back plate 1 and the conventionally designed snap-fit ​​structure around the middle sheet metal 3 cooperate with each other to assemble a backlight assembly.

[0037] The backlight assembly is then bonded to the display screen using the adhesive surfaces 1-3 around the one-piece die-cast backplate 1, and embedded into various applications to become the backlight part of electronic display devices.

[0038] The backlight assembly is connected to the whole machine via the automotive or other application mounting feet structure 1-7 on the back of the integrated die-cast backplate 1.

[0039] The appearance surfaces 1-8 on the back of the integrated die-cast back panel 1 are directly displayed as the appearance surfaces of the electronic display device.

[0040] The above embodiments employ an unconventional one-piece die-cast backplate. The back of this one-piece die-cast backplate is designed as a display screen exterior component, and can be customized in different colors according to customer preferences. It integrates the design of a conventional full-coverage backlight shell, minimizing the overall size and achieving an extremely thin profile, thus saving materials, reducing costs, and enhancing the aesthetics. The back of the one-piece die-cast backplate also features mounting feet for automotive or other applications, reducing the number of mounting feet, simplifying the production process, and further reducing costs. The one-piece die-cast backplate has structural adhesive dispensing steps around its perimeter, allowing for an extremely narrow bezel design during adhesive curing. Furthermore, the one-piece die-cast backplate features partially concealed recessed groove structures for sheet metal mounting ears, designed within the structural adhesive dispensing steps. In some areas, the reduced bezel width decreases the thickness of the sheet metal. The integrated die-cast back panel features raised dot structures around its perimeter, controlling the thickness of the structural adhesive and ensuring its bonding strength. A recessed structure for the backlight optical component's mounting ears is designed on the lower side of the integrated die-cast back panel, reducing the risk of light leakage in the mounting area and eliminating the need for raised dot structures on the backlight optical component itself. A flexible flat cable insertion hole structure is also designed on the lower side of the integrated die-cast back panel, enabling a seamless connection and improving the aesthetics while reducing the width of the lower bezel. The integrated die-cast back panel design eliminates the conventional perimeter edging structure, incorporating a micro-structure to prevent adhesive spillage. The display screen is suspended on the adhesive surface via structural adhesive bonding, realizing the concept of a bezel-less display.

[0041] The above embodiment adopts an unconventional design for the middle sheet metal. The middle sheet metal has a partial design with a hanging ear structure around its perimeter, which eliminates the need for the stepped structure supporting the middle sheet metal on the integrated die-cast back plate. This increases the expansion and contraction space of the backlight optical components and reduces the risk of light leakage around the backlight optical components. The middle sheet metal design eliminates the conventional side wall baffle structure, and the frame width reduces the thickness space of the middle sheet metal.
