Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically to a display device. Background Technology

[0002] In frameless backlight modules, due to bezel size limitations, the thickness of the PCB cover (PCB cover) on the side bonded to the chip-on-film (COF) is generally small, resulting in lower structural strength of the PCB cover. When bonding the COF and the frame using the PCB cover, poor adhesion can easily occur, leading to large gaps. The main reason for this poor adhesion is that the curved COF is not easily deformed, pushing out and deforming part of the PCB cover structure on the COF side. Poor adhesion between the PCB cover, COF, and frame will widen the bezel of the backlight module, and the COF will not be effectively protected. Summary of the Invention

[0035] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] Figure 1 A partial cross-sectional structural diagram of an exemplary display device is provided. Figure 1 As can be seen, the display device 1 includes a display panel 2, a frame 3, a backlight unit 4, a circuit film (e.g., COF), a circuit cover plate (e.g., PCBCOVER), and a housing 7. Among them, the frame 3, the backlight unit 4, the circuit film 5, and the circuit cover plate 6 constitute a four-sided frameless backlight module.

[0037] Specifically, the frame 3 includes a first support portion 3a and a second support portion 3b that are vertically connected; wherein, the first support portion 3a is located on the back of the display panel 2 and is joined to the display panel 2 through a bonding layer, for supporting the display panel 2; the second support portion 3b is vertically connected to one end of the first support portion 3a near the side of the display panel 2.

[0038] Specifically, the circuit film 5 is sandwiched between the display panel 2 and the first support portion 3a, and extends to the side of the second support portion 3b away from the backlight unit 4 and the side of the second support portion 3b away from the first support portion 3a.

[0039] Specifically, the circuit cover 6 includes an integrally formed first sub-cover 6a and second sub-cover 6b; wherein, the first sub-cover 6a is located on the side of the display panel 2 and is disposed corresponding to the second support portion 3b, and the second sub-cover 6b is perpendicularly connected to the end of the first sub-cover 6a away from the display panel 2. The first sub-cover 6a and the second sub-cover 6b cover the circuit film 5, which is used to achieve the bonding of the circuit film 5 with the frame 3 and to isolate the circuit film 5 from the external environment, which is conducive to achieving a narrow bezel and can also protect the circuit film 5 from corrosion and damage.

[0040] Specifically, the backlight unit 4 is located in the cavity formed by the frame 3 and the circuit cover plate 6. The housing 7 is integrally formed and located outside the circuit cover plate 6 and the backlight unit 4.

[0041] Understandable. Figure 1 The circuit film 5 is bent twice and applied to the surfaces of the first support portion 3a and the second support portion 3b of the frame 3. However, because the bent circuit film 5 is not easily deformed, it will push the structure of the circuit cover plate 6 that is attached to the circuit film 5 outward and deform, resulting in poor adhesion between the circuit cover plate 6, the circuit film 5, and the frame 3 during assembly. Poor adhesion between the circuit cover plate 6, the circuit film 5, and the frame 3 will cause the bezel of the display device 1 to widen, and the circuit film 5 will not be effectively protected.

[0042] Meanwhile, when assembling the frameless backlight module with the housing 7 to form the display device 1, the backlight module is usually fixed to the housing 7 by two methods: using strong magnets and screws. However, using strong magnets to fix the backlight module by magnetic force carries the risk of the backlight module falling off the housing, while the screw method requires a certain number of bolts on both the top and bottom sides of the housing 7, resulting in inconvenient assembly and high cost.

[0043] To address the aforementioned technical problems, this application provides... Figure 1 The structure of the display device shown has been improved, providing a new display device, which can be specifically described in the following embodiments.

[0044] like Figure 2 As shown, this application provides a display device 10, which includes a display panel 11, a frame 12, a circuit film 13, a circuit cover 14, a backlight unit 15, and a housing.

[0045] In one specific embodiment, the frame 12, the circuit film 13, the circuit cover plate 14, and the backlight unit 15 constitute a frameless backlight module.

[0046] Specifically, the display panel 11 includes, but is not limited to, a liquid crystal display panel.

[0047] Specifically, the frame 12 is located on the back of the display panel 11; the frame 12 includes a first support portion 12a that supports the display panel 11 and a second support portion 12b that is vertically connected to the end of the first support portion 12a.

[0048] Specifically, the first support part 12a and the second support part 12b are integrally formed.

[0049] Specifically, the first support portion 12a is arranged parallel to the display panel 11, and the first support portion 12a is fixedly connected to the back of the display panel 11 through the first bonding layer 18.

[0050] Specifically, the second support portion 12b is vertically connected to the first support portion 12a, and the second support portion 12b is located at one end of the first support portion 12a near the side of the display panel 11.

[0051] Understandably, the first support portion 12a and the second support portion 12b are located entirely on the back of the display panel 11, that is, in Figure 2 In the cross-sectional direction shown, the display panel 11 completely covers the first support portion 12a and the second support portion 12b, preventing the edges of the first support portion 12a and the second support portion 12b from extending beyond the side of the display panel 11, which is beneficial for narrowing the bezel.

[0052] Specifically, the circuit film 13 is located between the display panel 11 and the first support portion 12a and extends to the surface of the second support portion 12b.

[0053] In one embodiment, the circuit film 13 is bent from the side of the first support portion 12a near the display panel 11 to cover the surface of the second support portion 12b, and bent to cover the side of the second support portion 12b away from the first support portion 12a.

[0054] Specifically, the circuit thin film 13 includes, but is not limited to, a chip-on-film (COF) film.

[0055] Specifically, the circuit cover 14 is located on the side of the display panel 11 and extends to be attached to the circuit film 13 located on the surface of the second support portion 12b.

[0056] Specifically, the function of the circuit cover plate 14 is to make the circuit film 13 adhere to the frame 12. On the one hand, this helps to narrow the frame, and on the other hand, it can protect the circuit film 13, thereby improving the service life of the display device 10.

[0057] Specifically, the circuit cover 14 can be a PCB cover, but is not limited to this.

[0058] Specifically, the housing includes a first housing 16 located on the side of the circuit cover 14 away from the circuit film 13, and the first housing 16 is fitted to the circuit cover 14.

[0059] Specifically, the backlight unit 15 is located in the receiving groove formed by the first support portion 12a and the second support portion 12b.

[0060] Specifically, the edge of the backlight unit 15 near the display panel 11 is fixedly connected to the side of the first support portion 12a away from the display panel 11 via the second bonding layer 19, and the side of the backlight unit 15 is attached to the side of the second support portion 12b away from the circuit film 13.

[0061] Specifically, the frame 12 also includes at least one first connecting member 12c located on the side of the second support portion 12b near the circuit cover plate 14; the first housing 16 is provided with a second connecting member 21 corresponding to the first connecting member 12c on the side near the circuit cover plate 14; the frame 12 and the first housing 16 are detachably fixedly connected by the first connecting member 12c and the second connecting member 21.

[0062] Specifically, the first connecting member 12c includes a snap-fit ​​protrusion structure; the second connecting member 21 includes a groove structure that matches the snap-fit ​​protrusion structure.

[0063] Understandably, the portion of the snap-fit ​​protrusion structure away from the second support 12b has a certain inclination. Correspondingly, the shape of the groove structure matches the shape of the snap-fit ​​protrusion structure, so that the snap-fit ​​protrusion structure can achieve a fixing function when it is located in the groove structure.

[0064] Understandably, the frame 12 and the first housing 16 are detachably fixedly connected by the first connecting member 12c and the second connecting member 21. The circuit cover plate 14 and the circuit film 13 located between the first housing 16 and the second support part 12b can be clamped by the bonding force between the first housing 16 and the frame 12, so that the circuit cover plate 14, the circuit film 13 and the frame 12 are tightly fitted together, avoiding gaps between the three. In addition, the first connecting member 12c and the second connecting member 21 are detachably fixedly connected in the form of a snap fastener, which facilitates installation and makes the connection more secure, improving the reliability of the housing and backlight assembly.

[0065] Specifically, the first connecting member 12c is located around the circuit film 13 and the circuit cover plate 14. It is understandable that the first connecting member 12c is positioned away from the circuit film 13 and the circuit cover plate 14 to avoid requiring structural modifications to the circuit film 13 and the circuit cover plate 14, thus reducing development costs.

[0066] Specifically, the circuit cover 14 includes a first sub-cover 14a located on the side of the display panel 11 and corresponding to the second support portion 12b, and a second sub-cover 14b perpendicularly connected to the end of the first sub-cover 14a away from the display panel 11; the second sub-cover 14b is located on the side of the backlight unit 15 away from the first support portion 12a.

[0067] Specifically, the first sub-cover plate 14a and the second sub-cover plate 14b are integrally formed. The end of the first sub-cover plate 14a away from the second sub-cover plate 14b is flush with the display surface of the display panel 11. The first sub-cover plate 14a is completely attached to the circuit film 13 located on the surface of the second support portion 12b, and the second sub-cover plate 14b is completely attached to the circuit film 13 located on the side of the second support portion 12b away from the first support portion 12a.

[0068] Specifically, the end of the first main body portion 16a of the first outer shell 16 away from the first extension portion 16b is flush with the display surface of the display panel 11, but is not limited thereto.

[0069] Specifically, the housing also includes a second housing 17 that is detachably fixedly connected to the first housing 16; the second housing 17 is located at least on the side of the second sub-cover 14b away from the display panel 11, and is detachably fixedly connected to the second sub-cover 14b.

[0070] Understandably, the outer casing is composed of an independent first outer casing 16 and a second outer casing 17, which makes it easier to disassemble and assemble the outer casing. For example, the internal structure of the display device 10 can be disassembled and assembled by simply removing the second outer casing 17.

[0071] Specifically, the first housing 16 includes a first main body portion 16a located on the side of the first sub-cover plate 14a away from the circuit film 13, and a first extension portion 16b perpendicularly connected to one end of the first main body portion 16a near the second sub-cover plate 14b; the first extension portion 16b is located between the second sub-cover plate 14b and the second housing 17. The display device 10 also includes a third connecting member 22 that simultaneously and detachably connects the second housing 17, the first extension portion 16b, and the second sub-cover plate 14b.

[0072] Specifically, the third connecting member 22 includes a bolt; correspondingly, the second sub-cover plate 14b has a first threaded hole 23 on the side away from the backlight unit 15; the second outer shell 17 and the first extension 16b are respectively provided with a second threaded hole 24 and a third threaded hole 25 that are corresponding to and communicate with the first threaded hole 23. The diameters of the first threaded hole 23, the second threaded hole 24, and the third threaded hole 25 are the same and match the size of the bolt shank; the bolt shank is located in the first threaded hole 23, the second threaded hole 24, and the third threaded hole 25.

[0073] Understandably, the first outer shell 16, the second outer shell 17 and the circuit cover 14 are simultaneously and detachably fixed together by bolts. Only by removing the bolts can the internal structure of the display device 10 be disassembled and assembled, making the disassembly and assembly of the entire display device 10 more convenient.

[0074] Specifically, the second outer casing 17 is also provided with a countersunk hole 26 that communicates with the second threaded hole 24. The countersunk hole 26 is located on the side of the second threaded hole 24 away from the third threaded hole 25, and the diameter of the countersunk hole 26 is larger than the diameter of the second threaded hole 24; the head of the bolt is completely located in the countersunk hole 26.

[0075] Understandably, countersunk holes 26 are provided on the surface of the second housing 17 to accommodate the bolt heads, thus preventing the bolt heads from being exposed and improving the appearance of the display device 10.

[0076] Specifically, the circuit cover 14 also includes a protrusion 27 located on the side of the second sub-cover 14b away from the backlight assembly; a first threaded hole 23 is formed in the protrusion 27. A buffer pad 28 is also provided between the first extension 16b and the second sub-cover 14b; the buffer pad 28 is located on the periphery of the protrusion 27.

[0077] Specifically, the material of the cushioning pad 28 includes, but is not limited to, rubber.

[0078] Understandably, the buffer pad 28 serves a buffering function, which can prevent the bolts from exerting excessive clamping force on the second sub-cover plate 14b during the housing assembly process, thus avoiding damage to the circuit film 13 or the back tube unit and improving product yield.

[0079] Specifically, the second housing 17 includes a second main body portion 17a located on the side of the backlight unit 15 away from the display panel 11, and a second extension portion 17b vertically connected to the end of the second main body portion 17a near the first main body portion 16a. The second main body portion 17a has a first cutout portion 29 corresponding to the first extension portion 16b, and the first extension portion 16b is located in the first cutout portion 29 and is completely fitted to the second main body portion 17a. The side of the first main body portion 16a away from the first sub-cover plate 14a has a second cutout portion 30 corresponding to the second extension portion 17b, and the second extension portion 17b is located in the second cutout portion 30 and is completely fitted to the first main body portion 16a. The side of the second extension portion 17b away from the first sub-cover plate 14a and the side of the first main body portion 16a away from the first sub-cover plate 14a are on the same plane.

[0080] Specifically, the first extension 16b of the first outer shell 16 and the second main body 17a of the second outer shell 17 are aligned at the position of the first cutout 29, and the overall thickness of the overlapping portion is the same as the thickness of the second main body 17a of the second outer shell 17; the second extension 17b of the second outer shell 17 and the first main body 16a of the first outer shell 16 are aligned at the position of the second cutout 30, and the overall thickness of the overlapping portion is the same as the thickness of the first main body 16a of the first outer shell 16. This design allows for a detachable and fixed connection between the first outer shell 16 and the second outer shell 17 while avoiding increasing the thickness of the outer shell, which is beneficial for achieving a thinner and more borderless design of the display device 10, and can also improve the aesthetic appearance of the display device 10.

[0081] Specifically, the backlight unit 15 includes a back plate 31, a backlight source 32, a reflective layer 33, a light guide plate 34, and an optical component 35.

[0082] Specifically, the backplate 31 includes an integrally formed first sub-backplate 31a and a second sub-backplate 31b. The first sub-backplate 31a is located on the side of the second sub-cover plate 14b near the display panel 11, and the reflective layer 33, the light guide plate 34, and the optical components 35 are sequentially stacked on the first sub-backplate 31a. The second sub-backplate 31b is perpendicularly connected to the end of the first sub-backplate 31a near the second support portion 12b; the second sub-backplate 31b is fitted to the second support portion 12b, and the backlight 32 is located between the second sub-backplate 31b and the light guide plate 34.

[0083] Specifically, the side of the optical component 35 away from the light guide plate 34 is fixedly connected to the first support portion 12a through the second bonding layer, and the backlight 32 is fixedly connected to the second sub-backplate 31b through the third bonding layer 20.

[0084] Understandably, the first housing 16 and the frame 12 are detachably and fixedly connected to the side of the backlight unit 15 by a snap-fit ​​method, and the first housing 16, the second housing 17 and the circuit cover plate 14 are detachably and fixedly connected to the back of the backlight unit 15 by bolts, so that the backlight unit 15 is fixed in the receiving cavity formed by the frame 12 and the circuit cover plate 14. This connection method makes the assembly and fixing of the housing and the backlight module more reliable.

[0085] Meanwhile, existing display devices have a monolithic casing, requiring a certain number of bolts for fixing different parts of the casing (e.g., the top and bottom sides) during assembly, making the assembly process more complex and increasing the number of bolts used, resulting in higher costs. In contrast, the casing of the display device 10 in this embodiment is a split design, with the first casing 16 fixedly connected to the frame 12 via a snap-fit ​​mechanism, making assembly more convenient. Furthermore, only the second casing 17 needs to be fixedly connected to both the first casing 16 and the circuit cover plate 14 with bolts, effectively reducing the number of bolts used and helping to reduce production costs.

[0086] It should be noted that this application only describes the specific structure of the side (top side) of the display device 10 where the circuit film 13 is provided. It can be understood that the outer shell of the other side of the display device 10, which is opposite to the top side, can also be an independent shell, and the shell can also be detachably fixed to the internal frame 12 by a snap-fit.

[0087] Therefore, the display device 10 provided in this application embodiment has the following advantages: on the one hand, it can improve the fit between the circuit cover plate 14, the circuit film 13 and the frame 12, avoid structural deformation and avoid gaps between the three, thereby achieving a frameless design and improving the protection effect of the circuit film 13; on the other hand, it can improve the reliability and aesthetics of the assembly of the housing and the backlight module; and furthermore, it makes the disassembly and assembly process of the housing and the backlight module simpler and cheaper.

[0088] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0089] The above provides a detailed description of a display device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
