Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a folded flexible ribbon cable and an LED display device. Background Technology

[0002] Flexible flat cables are a common type of connector used in electronic devices. They are flexible and bendable, and have a planar structure with integrated conductors. Therefore, flexible flat cables can be used in a wide variety of electronic devices.

[0003] There are many types of flexible ribbon cables on the market, such as the Chinese patent with publication number CN202796144U. When the two ends of the flexible ribbon cable are connected to the motherboard and the display driver board respectively, signal interference will occur because the monitor has multiple ribbon cables with different functions and multiple ribbon cables transmit signals in parallel in a limited space. In addition, some monitors have built-in speakers, and the motherboard is close to the speaker. The sound emitted by the speaker causes the motherboard and the ribbon cable to vibrate. Furthermore, there are no fixed parts in the middle of the ribbon cable, which generates noise. When the above situations exist, the signal output from the motherboard is prone to instability when passing through the ribbon cable, resulting in poor display effect or abnormal function of the display device. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a folded flexible ribbon cable and LED display device that prevents noise interference, signal interference, and loosening of the ribbon cable body, and ensures the normal operation of the display device.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0028] Please see Figures 1 to 3This is an embodiment of the present invention: a folded flexible ribbon cable 10, comprising a first connector 100, a ribbon cable body 200, and a second connector 300. Both ends of the ribbon cable body 200 are connected to the first connector 100 and the second connector 300, respectively. The first connector 100 is used to connect to the display motherboard, and the second connector 300 is used to connect to the display driver board. The ribbon cable body 200 includes a first surface layer, a ribbon cable layer, and a second surface layer. The two sides of the ribbon cable layer are respectively attached to the first surface layer and the second surface layer. The first surface layer is positioned facing the inner wall of the display housing, and the second surface layer is positioned away from the inner wall of the display housing. The folded flexible ribbon cable 10 also includes a sound-absorbing shielding structure 400, at least one folded adhesive tape 500, and several external adhesive sheets 600. One side of the ribbon cable body 200 is adhered to the side of the first surface layer facing away from the ribbon cable layer. The other sides of multiple outer adhesive strips 600 are positioned facing the inner wall of the display housing. The ribbon cable body 200 has at least one bend area 201, and each bend adhesive strip 500 is adhered to the corresponding bend area 201. The sound-absorbing shielding structure 400 includes a sound-absorbing sponge layer 410, a first adhesive layer 420, an aluminum foil shielding layer 430, and a second adhesive layer 440. The first adhesive layer 420 is disposed between the sound-absorbing sponge layer 410 and the aluminum foil shielding layer 430, and the second adhesive layer 440 is disposed between the aluminum foil shielding layer 430 and the first surface layer, and is connected to the side of the first surface layer facing away from the ribbon cable layer, so that the entire sound-absorbing shielding structure 400 is adhered to the ribbon cable body 200. The sound-absorbing sponge layer 410 also faces the inner wall of the display housing. It can be understood that the bend area 201 is the area formed when the ribbon cable body 200 is bent.

[0029] In this embodiment, the first surface layer is a printed surface layer, and the second surface layer is a composite material surface layer.

[0030] Understandable. Figure 4 This is a physical diagram of the angled flexible ribbon cable 10 in this solution, corresponding to... Figure 1 The diagram shown is a structural schematic.

[0031] In this embodiment, the angled flexible ribbon cable 10 has a sound-absorbing shielding structure 400 and multiple external adhesive sheets 600. The sound-absorbing shielding structure 400 has a sound-absorbing sponge layer 410 and an aluminum foil shielding layer 430. The sound-absorbing sponge layer 410 has the function of absorbing noise generated by the vibration of the motherboard and the ribbon cable, and the aluminum foil shielding layer 430 has the function of shielding external signal interference. At the same time, the two sides of the external adhesive sheets 600 are respectively bonded to the first surface layer and the inner wall of the display device. The above structure can prevent noise interference and signal interference, and prevent the ribbon cable body 200 from loosening, so that the display device can work normally.

[0032] Furthermore, both the first adhesive layer 420 and the second adhesive layer 440 are made of PET adhesive.

[0033] In another embodiment, the number of corner adhesive tapes 500 and the number of corner regions 201 are both multiple and equal, such that each corner adhesive tape 500 is adhered to the corresponding corner region 201.

[0034] like Figure 2 As shown, in one embodiment, at least one outer adhesive sheet 600 is also adhered to a corresponding corner adhesive tape 500. In this embodiment, a portion of the outer adhesive sheet 600 is adhered to the ribbon cable body 200 to prevent the ribbon cable body 200 from shaking, while another portion of the outer adhesive sheet 600 is also adhered to the corner adhesive tape 500 to prevent the corner adhesive tape 500 from detaching from the corner area 201.

[0035] like Figure 1 As shown, in one embodiment, the sound-absorbing sponge layer 410 has a square cross-section. Of course, in other embodiments, the cross-section of the sound-absorbing sponge layer 410 can also be rectangular, circular, pentagonal, or other shapes.

[0036] In one embodiment, the sound-absorbing sponge layer 410 has a cross-sectional length of 45mm-50mm. In this embodiment, the sound-absorbing sponge layer 410 has a cross-sectional length of 49mm, meaning the four sides of the sound-absorbing sponge layer 410 are 49mm long. In another embodiment, the aluminum foil shielding layer 430 has a cross-sectional length of 49mm.

[0037] Furthermore, the thickness of the sound-absorbing sponge layer 410 is 2mm-3mm. In this embodiment, the thickness of the sound-absorbing sponge layer 410 is 2mm.

[0038] In one embodiment, the bend angle of the folded region 201 is 90°. It can be understood that when the folded region 201 is 90°, it effectively bypasses other drive boards or components, preventing signal interference caused by the ribbon cable body 200 covering other drive boards or components. That is, the ribbon cable body 200 connects to the display motherboard and display drive board without obstructing other drive boards or components. Further, the bend angle of the folded region 201 is the angle formed when one straight section of the ribbon cable body 200 intersects with another straight section of the ribbon cable body 200, with the bent portion as the base point. Of course, the angle formed by the folded region 201 can be adjusted according to the internal structure distribution of the display device to adapt to more types of display devices.

[0039] Combination Figure 1 and Figure 2As shown, in one embodiment, the corner adhesive tape 500 includes a first tape body 510, a transition tape body 520, and a second tape body 530 connected in sequence. The first tape body 510 and the second tape body 530 are both located on the front side of the corner region 201, and the transition tape body 520 is located on the back side of the corner region 201. It can be understood that the corner adhesive tape 500 is bent and bonded to both sides of the corner region 201. Specifically, the first tape body 510 and the second tape body 530 are located on the first surface layer, and the transition tape body 520 is located on the second surface layer, to enhance the adhesive strength between the corner adhesive tape 500 and the corner region 201. In this embodiment, as... Figure 2 As shown, a portion of the structure of the first tape 510 and a portion of the structure of the second tape 530 overlap. When the first tape 510 becomes loose, the second tape 530 prevents the first tape 510 from loosening by adhering to the ribbon cable body 200; conversely, when the second tape 530 becomes loose, the first tape 510 prevents the second tape 530 from loosening by adhering to the ribbon cable body 200. It can be understood that the overlapping area is the portion where the first tape 510 and the second tape 530 overlap when bonded. In this embodiment, the front side of the corner region 201, the transition tape 520, and the first surface layer are disposed on the same surface; the back side of the corner region 201, the first tape 510, the second tape 530, and the second surface layer are disposed on the same surface.

[0040] In one embodiment, at least one outer adhesive tab 600 is bonded to the overlapping area. It is understood that after the first tape 510 and the second tape 530 overlap, the outer adhesive tab 600 adheres to the overlapping portion, further preventing the first tape 510 or the second tape 530 from detaching and ensuring the bonding strength between the corner adhesive tape 500 and the ribbon cable body 200. In this embodiment, the overlapping area is located on the back side of the corner area 201.

[0041] In one embodiment, the corner tape 500 is made of acetate cloth. It is understood that acetate cloth has insulating and abrasion-resistant properties, which can reduce wear on the corner area 201 and prevent wear from reducing the shielding effect of the ribbon cable layer.

[0042] This disclosure also provides an LED display device, including a display housing, a display motherboard, a display driver board, and a folded flexible ribbon cable 10 according to any of the above embodiments. The display motherboard, the display driver board, and the folded flexible ribbon cable 10 are all located inside the display housing. The two ends of the folded flexible ribbon cable 10 are electrically connected to the display motherboard and the display driver board, respectively. It can be understood that when the two ends of the folded flexible ribbon cable 10 are connected to the display motherboard and the display driver board, the ribbon cable body 200 can be glued to the inner wall of the display housing by the external adhesive tab 600 to prevent the ribbon cable body 200 from being interfered with by external signals and to prevent the ribbon cable body 200 from vibrating due to sound emitted by the internal speaker.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] The aforementioned angled flexible ribbon cable 10 has a sound-absorbing shielding structure 400 and multiple external adhesive sheets 600. The sound-absorbing shielding structure 400 has a sound-absorbing sponge layer 410 and an aluminum foil shielding layer 430. The sound-absorbing sponge layer 410 has the function of absorbing noise generated by the vibration of the motherboard and the ribbon cable, and the aluminum foil shielding layer 430 has the function of shielding external signal interference. Meanwhile, the two sides of the external adhesive sheets 600 are respectively bonded to the first surface layer and the inner wall of the display device. The above structure can prevent noise interference and signal interference, and prevent the ribbon cable body 200 from loosening, so that the display device can work normally.
