Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a light bar installation structure and a display device. Background Art

[0002] Display devices such as LCD TVs are widely used, providing great convenience for people's life, study, work and other activities. The backlight module is an important component of LCD TVs, which usually consists of back panels, light strips, reflectors, optical films, diffusers and other components. At present, the light strips are generally installed on the inner side of the back panel by gluing or screwing.

[0003] However, in order to obtain a sufficiently large installation space, the back panel is usually designed as a concave structure, so that the edge of the back panel is formed into a slanted wall, and there is an R-angle transition between the slanted wall and the back panel body. Correspondingly, the reflector installed on the inner side of the back panel and the corresponding part of the slanted wall are also slanted surfaces. On the one hand, since the tolerance of the R-angle of the back panel is large, in order to avoid the R-angle interfering with the installation of the light bar, the distance between the light bar and the slanted wall of the back panel cannot be too close, resulting in a waste of space; on the other hand, because the distance between the light panel and the slanted wall is too large, and due to the space limitation between the slanted wall and the slanted surface, the reflector needs to have a gap to accommodate the wiring socket of the light bar. However, the existence of the gap will cause problems such as light and shadow, affecting the display effect. Summary of the invention

[0004] Based on this, it is necessary to provide a light bar installation structure and a display device to address the problem of wasting space and affecting display effects.

[0005] In a first aspect of the present application, a light bar installation structure is provided, comprising:

[0006] A back plate, the back plate comprising a plate body and an inclined plate, the edge of the plate body being a support portion, a support protrusion being convexly provided on the surface of the support portion, the inclined plate being connected to the edge of the support portion and being inclined toward the inner side of the back plate;

[0007] a reflector sheet, the reflector sheet being arranged on the inner side of the back plate, and the side of the reflector sheet being provided with an inclined portion, the inclined portion being spaced apart from the supporting portion and enclosing an accommodating space; and

[0008] A light bar, the light bar comprising a light board and a wiring socket, the light board comprising a mounting end, the wiring socket being arranged at the mounting end, the mounting end extending into the accommodating space and resting on the supporting protrusion, the supporting protrusion being configured to raise the light board relative to the supporting portion, so that the mounting end can abut against the inclined plate or be gap-matched with the inclined plate in the S direction, so that the wiring socket can be completely accommodated in the accommodating space.

[0009] In the light bar installation structure of the present scheme, since the support portion is designed to be formed at the edge of the plate body of the back plate, and a support protrusion is convexly formed on the support portion, when the light bar is installed to the inner side of the back plate, the support protrusion can directly support the installation end of the light board in contact, thereby forming an installation positioning for the light bar, and at the same time, the support protrusion can raise the installation position of the light bar compared to the support portion; on this basis, the reflective sheet is then installed to the inner side of the back plate, and the inclined portion of the reflective sheet can be spaced apart from the support portion and enclose a accommodating space, at this time, the installation end and the wiring socket arranged on the installation end are both in the accommodating space. Since the mounting end of the light strip is raised, the mounting end of the light panel can be placed as close to the inclined plate as possible and abut against the inclined plate or cooperate with the inclined plate in the S direction to make fuller use of the installation space on the inner side of the back panel. Precisely because the mounting end can be arranged closer to the inclined plate, the wiring socket on the mounting end can be fully extended into the accommodating space, so that the accommodating space can completely accommodate the wiring socket. Therefore, there is no need to open a notch on the reflective sheet to accommodate the wiring socket to prevent interference, thereby solving the problem of light and shadow caused by the presence of the notch and improving the display effect.

[0010] The technical solution of this application is further described below:

[0011] In one embodiment, the area of ​​the accommodating space close to the inclined plate includes an installation area, the height of the installation area changes gradually from the side of the support portion away from the inclined plate to the direction of the inclined plate, and the wiring seat is arranged in the installation area.

[0012] In one of the embodiments, a transition fillet is formed between the inclined plate and the support portion, and the mounting end is disposed above the transition fillet.

[0013] In one embodiment, the support protrusion has a support surface away from the support portion, and the support surface is supported and matched with the back surface of the lamp board; an adhesive is provided on the back of the lamp board, and the back of the lamp board is bonded and fixed to the support surface through the adhesive;

[0014] Alternatively, a positioning groove is formed on the back side of the lamp panel, and the end of the supporting protrusion away from the supporting part is arranged in the positioning groove.

[0015] In one of the embodiments, lamp beads are arranged on the lamp board, and windows are arranged at positions of the reflective sheet corresponding to the lamp beads, and the lamp beads extend out of the windows.

[0016] In one of the embodiments, the wiring seat is arranged close to the end surface of the mounting end opposite to the inclined plate.

[0017] In one embodiment, the wiring seat is provided with a wiring portion, and the wiring portion and the inclined plate are arranged at a preset angle so that the wiring direction adapted to the wiring portion is arranged side by side and spaced apart from the inclined plate.

[0018] In one of the embodiments, the inner side wall of the back plate is formed with a reinforcing rib, and the supporting protrusion is arranged on the reinforcing rib.

[0019] In one embodiment, one end of the reinforcing rib in the length direction is formed at the supporting portion, and the other end of the reinforcing rib in the length direction extends to the inclined plate.

[0020] In one of the embodiments, a groove is formed on the outer side surface of the back plate at a position corresponding to the reinforcing rib, and a concave hole is formed on the bottom wall of the groove at a position corresponding to the supporting protrusion.

[0021] In a second aspect of the present application, a display device is further provided, which includes the light bar mounting structure as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The backlight module is an important component of a display device (such as a liquid crystal television), which is usually composed of a back panel 10, a light bar 40, a reflector 20 and other components. The light bar 40 is generally installed on the inner side of the back panel 10 by gluing or screwing. However, in order to obtain a sufficiently large installation space, the back panel 10 is usually designed as a concave structure, so that the edge of the back panel 10 is formed into an inclined wall, and there is an R-angle transition between the inclined wall and the main body of the back panel 10. Correspondingly, the reflective sheet 20 installed on the inner side of the back panel 10 and the corresponding part of the inclined wall are also inclined surfaces. On the one hand, since the tolerance of the R-angle of the back panel 10 is relatively large, in order to avoid the R-angle interfering with the installation of the light bar 40, the distance between the light bar 40 and the inclined wall of the back panel 10 cannot be too close, thereby causing a waste of space; on the other hand, because the distance between the light board 41 and the inclined wall is too large, and due to the space limitation between the inclined wall and the inclined surface, the reflective sheet 20 needs to have a gap to accommodate the wiring socket 42 of the light bar 40. However, the existence of the gap will cause problems such as light and shadow, affecting the display effect.

[0040] In view of the above problems, the present invention proposes an improved light bar mounting structure 100, by making a supporting protrusion 14 on the inner side of the back plate 10, and then mounting the mounting end 411 of the light bar 40 on the supporting protrusion 14, so that the supporting protrusion 14 can lift the mounting end 411 of the light bar 40, so that the mounting end 411 of the light bar 40 can be as close to the inclined plate 12 of the back plate 10 as possible, so that the mounting end 411 and the wiring socket 42 mounted thereon can be fully extended into the accommodating space 30 formed by the inclined plate 12 of the back plate 10 and the inclined portion 21 of the reflective sheet 20, that is, avoiding interference between the mounting end 411 and the R angle, and also making the wiring socket 42 avoid the inclined portion 21, so that there is no need to open a gap on the reflective sheet 20 to avoid the wiring socket 42, thereby improving space utilization and enhancing display effects.

[0041] See Figure 1, Figure 2 and Figures 4 to 6 , is a light bar installation structure 100 shown in an embodiment of the present application, comprising a back plate 10, a reflective sheet 20 and a light bar 40. The back plate 10, the reflective sheet 20 and the light bar 40 are all main components of the backlight module of a display device (such as a liquid crystal television), wherein the functions of the back plate 10 mainly include the following points: on the one hand, it provides support: as the basic structure of the backlight module, the back plate 10 can provide stable support so that other components such as the reflective sheet 20 and the light bar 40 can be correctly installed and fixed; on the other hand, it provides heat dissipation: the back plate 10 is usually made of metal material and has good heat dissipation performance. It can help the light bar 40 dissipate heat, keep the temperature of the backlight module within a suitable range, and prevent overheating; furthermore, it provides isolation: the back plate 10 can play an isolation role, preventing the light of the light bar 40 from penetrating to other parts, and ensuring that the backlight only illuminates the area behind the LCD screen.

[0042] The light bar 40 is a key component for providing a backlight source, and its functions mainly include the following points. On the one hand, it provides a light source: the light bar 40 is the light source in the backlight module, which can provide backlight to illuminate the image behind the LCD screen; on the other hand, it provides uniform backlight: the light bar 40 can provide evenly distributed backlight, so that the brightness of the surface of the LCD screen is more uniform, which can avoid uneven brightness and improve image quality and viewing experience; and it is used to adjust the brightness and contrast: the brightness of the light bar 40 can be controlled by adjusting parameters such as current and voltage, thereby realizing the adjustment of the brightness and contrast of the LCD TV.

[0043] Specifically in this case, the back plate 10 is set to be rectangular, and the corresponding reflector sheet 20 is also rectangular. The light bar 40 is also set to be rectangular, but the number of light bars 40 is more than one. When the light bar 40 is installed, the length direction of the light bar 40 is arranged in the same direction as the length direction of the back plate 10, and multiple light bars 40 are arranged at equal intervals along the width direction of the back plate 10. Multiple light bars 40 are arranged at the same time to obtain more abundant light source intensity. The light bar 40 is installed between the back plate 10 and the reflector sheet 20.

[0044] Please continue to refer to Figure 1 and Figure 7 The light bar 40 includes a light board 41 and a wiring socket 42. In addition, a plurality of lamp beads 43 are arranged at intervals along the length direction of the light board 41. When the wiring socket 42 is electrically connected to the control device, the light board 41 is powered on and the lamp beads 43 can be lit.

[0045] In order to avoid obstruction, a window 22 is provided at a position of the reflective sheet 20 corresponding to the lamp beads 43 , and each lamp bead 43 extends out from a corresponding window 22 .

[0046] Please continue to refer to Figure 1. Figure 5 and Figure 7 The back panel 10 includes a panel body 11 and an inclined panel 12. The panel body 11 is similar to a flat plate structure, and the inclined panel 12 is inclined toward the inner side of the panel body 11 in order to obtain more ample installation space for the back panel 10, so that the back panel 10 is formed into a concave structure as a whole.

[0047] Specifically, the edge of the plate body 11 is a support portion 111, which is specifically located at both ends of the length direction of the plate body 11, and a support protrusion 14 is convexly provided on the surface of the support portion 111. The inclined plate 12 is connected to the edge of the support portion 111 and is inclined toward the inner side of the back plate 10, and a transition fillet 13 (i.e., the above-mentioned R angle) is formed between the inclined plate 12 and the support portion 111.

[0048] Optionally, the supporting protrusion 14 is set to be a regular shape such as a cylinder, a truncated cone, or other irregular shapes, which can be selected according to actual needs.

[0049] The reflector 20 is disposed inside the back plate 10, and the edge of the reflector 20 is provided with a bevel 21. It can be understood that the reflector 20 is provided with the bevel 21 to adapt to the concave structure of the back plate 10, so as to facilitate the normal installation of the reflector 20 on the back plate 10.

[0050] The inclined portion 21 and the support portion 111 are spaced apart and enclose a receiving space 30. The lamp board 41 includes a mounting end 411, and a wiring socket 42 is disposed at the mounting end 411. The mounting end 411 extends into the receiving space 30 and is placed on the support protrusion 14. Specifically, the area of ​​the receiving space 30 close to the inclined plate 12 includes an installation area, and the height of the installation area increases from the side of the support portion 111 away from the inclined plate 12 to the direction of the inclined plate 12 (i.e., the direction of the arrow S in the figure), and the wiring socket 42 is disposed in the installation area. The mounting end 411 is disposed above the transition fillet 13, and the support protrusion 14 is configured to raise the lamp board 40 relative to the support portion 111, so that the mounting end 411 can abut against the inclined plate 12 or be gap-matched with the inclined plate 12 in the S direction, so that the wiring socket 42 can be completely accommodated in the installation area of ​​the receiving space 30.

[0051] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the light bar installation structure 100 of this solution, since the support portion 111 is designed to be formed at the edge of the plate body 11 of the back plate 10, and a support protrusion 14 is convexly formed on the support portion 111, when the light bar 40 is installed to the inner side of the back plate 10, the support protrusion 14 can directly support the installation end 411 of the light plate 41, thereby forming an installation positioning for the light bar 40, and at the same time, the support protrusion 14 can raise the installation position of the light bar 40 compared to the support portion 111; on this basis, the reflective sheet 20 is then installed to the inner side of the back plate 10, and the inclined portion 21 of the reflective sheet 20 can be spaced apart from the support portion 111 and enclose a accommodating space 30. At this time, the installation end 411 and the wiring seat 42 arranged on the installation end 411 are both in the installation area of ​​the accommodating space 30. Since the height of the installation area of ​​the accommodating space 30 is along the side of the support portion 111 away from the inclined plate 12 to the inclined The direction of the board 12 changes in an incremental manner, and the supporting protrusion 14 can lift the mounting end 411 and suspend it above the transition fillet 13. Therefore, the mounting end 411 of the light board 41 can be as close to the inclined board 12 as possible and abut against the inclined board or match with the inclined board in the S direction, so as to make more effective use of the mounting space inside the back board 10 and avoid interference between the transition fillet 13 and the mounting end 411. Because the mounting end 411 can be arranged closer to the inclined board 12, the wiring socket 42 on the mounting end 411 can be fully extended into the installation area with a larger height of the accommodating space 30, so that the accommodating space 30 can fully accommodate the wiring socket 42 (for example, the wiring socket 42 and the inclined portion 21 of the reflective sheet 20 are gap-matched or just in contact), thereby eliminating the need to open a notch on the reflective sheet 20 to accommodate the wiring socket 42 to prevent interference, thereby solving the problem of light and shadow caused by the existence of the notch and improving the display effect.

[0052] See also Figure 5Benefiting from the inclined posture characteristics of the inclined plate 12, when the support protrusion 14 lifts the mounting end 411 of the lamp board 41 higher, the distance between the end face of the mounting end 411 facing the inclined plate 12 and the board surface of the inclined plate 12 becomes larger, and therefore the mounting end 411 can move horizontally to the left (i.e., in the S direction) and get closer to the inclined plate 12, thereby driving the wiring seat 42 to move synchronously to the left. Since the height of the area closer to the left of the accommodating space 30 is larger, it can not only accommodate the mounting end 411 and the wiring seat 42 well, but also make the wiring seat 42 further away from the inclined portion 21 of the reflective sheet 20 to maintain an anti-interference distance. This is the technical principle for solving the technical problem in this case.

[0053] Based on the above embodiment, the support protrusion 14 has a support surface away from the support portion 111, and the support surface cooperates with the back of the lamp board 41. The support surface is in planar contact with the back of the lamp board 41, and the support stability is good, thereby ensuring that the support protrusion 14 is firmly installed on the lamp board 41.

[0054] For example, the support surface may be any one of a circle, a square, a triangle, etc., and the support surface is a horizontal surface, so that it can fit with the back plane of the light board 41 to obtain a better support effect.

[0055] It is necessary to explain that, according to actual needs, more than one supporting protrusion 14 can be set, for example, two, three or even more can be set at the same time, but there is no specific limitation on the arrangement of two or more supporting protrusions 14, as long as it can be ensured that two or more supporting protrusions 14 can simultaneously support and stabilize the light bar 40.

[0056] Furthermore, in order to improve the mounting firmness of the light bar 40 on the supporting protrusion 14, an adhesive is provided on the back of the light board 41, and the back of the light board 41 is bonded and fixed to the supporting surface through the adhesive. The adhesive provides adhesive force, thereby bonding and fixing the light board 41 to the supporting protrusion 14, preventing the light bar 40 from shifting and falling off from the supporting protrusion 14 under vibration or other conditions.

[0057] Optionally, the adhesive member may be, but is not limited to, double-sided tape, glue, etc.

[0058] Of course, in other optional embodiments, the lamp panel 41 and the supporting protrusion 14 may be assembled and fixed by vacuum adsorption, magnetic attraction, mechanical clamping, etc.

[0059] Or, as an alternative to the above embodiment, Figure 5As shown, a positioning groove 412 is formed on the back of the lamp board 41, and the end of the support protrusion 14 away from the support portion 111 is arranged in the positioning groove 412. That is, by providing the positioning groove 412, the end of the support protrusion 14 is inserted into the positioning groove 412 to form a tight fit with the groove wall of the positioning groove 412, and the lamp board 41 can also be installed and fixed, so as to improve the installation stability of the light bar 40 on the support protrusion 14.

[0060] Please continue reading Figure 5 and Figure 7 On the basis of any of the above embodiments, the wiring holder 42 is preferably arranged near the end surface of the mounting end 411 opposite to the inclined plate 12. That is, the wiring holder 42 is preferably arranged near the edge of the mounting end 411 facing the inclined plate 12, so that when the support protrusion 14 only needs to be designed with a small height, the mounting end 411 only needs to move a small distance horizontally toward the inclined plate 12, so that the wiring holder 42 can be more obviously away from the inclined portion 21, thereby avoiding the reflective sheet 20, so as to avoid interference with the reflective sheet 20 or need to open a gap on the reflective sheet 20 to avoid the wiring holder 42.

[0061] In addition, properly controlling the height of the support protrusion 14 can also prevent the light bar 40 from being too far away from the board body 11 to form a large gap, resulting in waste of installation space inside the back plate 10, that is, achieving a reasonable layout of the light bar 40 inside the back plate 10 and full utilization of the space.

[0062] The wiring socket 42 disposed on the light board 41 is used to be connected to the controller point through a connecting line, so as to supply power to the light bar 40 and control the lighting and extinguishing, light intensity and other working states of the light bar 40.

[0063] In the conventional technology, the wiring portion 421 of the wiring socket 42 is directly arranged toward the inclined plate 12 of the back plate 10. Therefore, in order to facilitate the wiring operation, it is necessary to reserve at least one finger position (i.e., a space for accommodating fingers) between the wiring socket 42 and the inclined plate 12. The finger position will occupy space, so that the mounting end 411 of the lamp board 41 and the wiring socket 42 cannot be too close to the inclined plate 12, which also causes the wiring socket 42 to be too close to the inclined portion 21, requiring the reflector 20 to have a gap to accommodate and avoid the wiring socket 42. To address this problem, in one embodiment of the present application, the wiring socket 42 is provided with a wiring portion 421, and the wiring portion 421 is arranged at a preset angle to the inclined plate 12, so that the wiring direction adapted to the wiring portion 421 is arranged side by side with the inclined plate 12.

[0064] Specifically, the wiring portion 421 can be set as a wiring slot, a wiring terminal, etc. The wiring seat 42 is horizontally rotated 90° (i.e., deflected by a preset angle) along the front of the light board 41, so that the wiring portion 421 can be adjusted from facing the inclined plate 12 so that the wiring direction is perpendicular to the inclined plate 12 to the wiring portion 421 being deflected to the board surface parallel to the inclined plate 12 so that the wiring direction is arranged side by side with the inclined plate 12. When the light bar 40 is installed, the wiring operation can be performed in the ample space on one side of the width direction of the light bar 40 without being blocked by the interference of the inclined plate 12, which facilitates the wiring operation.

[0065] It is necessary to explain that the opposite ends of the length direction of the plate body 11 are provided with inclined plates 12 and supporting parts 111, and correspondingly, the opposite ends of the length direction of the reflective sheet 20 are also provided with inclined parts 21, and the supporting parts 111 at both ends are provided with supporting protrusions 14, so that the opposite ends of the length direction of the light strip 40 can form installation supports at the same time.

[0066] Please continue reading Figure 5 and Figure 7 In addition, based on any of the above embodiments, the inner wall of the back plate 10 is formed with a reinforcing rib 50, and the supporting protrusion 14 is arranged on the reinforcing rib 50. By making the reinforcing rib 50 on the inner wall of the back plate 10, the structure of the back plate 10 can be strengthened, and the thin structure and material selection design of the back plate 10 are met, while ensuring that the strength of the back plate 10 is high enough and not easy to deform.

[0067] like Figure 7 As shown, further, based on the above embodiment, one end of the reinforcing rib 50 in the length direction is formed on the support portion 111, and the length direction of the reinforcing rib 50 (i.e. Figure 7 The other end of the support portion 111 (in the direction of the arrow W) extends to the inclined plate 12. Since the inclined plate 12 is obliquely connected to the edge of the support portion 111 and a transition fillet 13 is formed between the support portion 111 and the inclined plate 12, this part of the structure will be a weak point. Under the action of external force compression or impact, this part of the structure is more likely to deform. Therefore, the reinforcing rib 50 is arranged to extend from the support portion 111 across the transition fillet 13 and onto the inclined plate 12, so that the structure of the bent structure can be reinforced, thereby improving the ability of the back plate 10 to cope with external pressure or impact.

[0068] Please continue reading Figure 3In another embodiment, a groove 60 is formed on the outer side surface of the back plate 10 at a position corresponding to the reinforcing rib 50, and a concave hole 70 is formed on the bottom wall of the groove 60 at a position corresponding to the supporting protrusion 14. Compared with the method of installing and fixing a separate supporting protrusion 14 on the inner side wall surface of the back plate 10 by welding or other methods, the present application reasonably designs the mold structure so that the back plate 10, the reinforcing rib 50 and the supporting protrusion 14 can be formed by one-time processing (such as stamping), which reduces the processing difficulty and cost, reduces the process steps, and improves the production efficiency of the back plate 10; in addition, it can also enable the back plate 10, the reinforcing rib 50 and the supporting protrusion 14 to obtain better overall structural performance.

[0069] In addition to the above, the present application further provides a display device, which includes the light bar mounting structure 100 as described in any of the above embodiments.
