Description

Technical Field

[0001] The present disclosure relates to the field of electronic devices, and more particularly, to an LED display device. Background Art

[0002] In the prior art, a single large-sized LED display device has a relatively large size and weight, which is not conducive to directly producing an integrated large-sized LED advertising screen, such as a 100-inch one. Moreover, the larger the area, the greater the challenges to the connection stability of the corresponding carrier board of the LED and the heat dissipation on the carrier board.

[0003] Taking the large-sized LED display device on an e-commerce website as an example, its large area is achieved by splicing multiple carrier boards provided with LEDs, as Figure 1 shown:

[0004] Figure 1 In, components shown in multiple longitudinal thick-line areas from left to right are involved to ensure the connection of the carrier boards on both sides. The carrier boards on both sides of the thick-line area have through holes extending in the Z-axis direction. Although Figure 1 the prior art shown makes the connection of the spliced carrier boards firm, the thick-line area obviously occupies an area, and the components shown in the thick-line area affect the ventilation of the carrier board and even the light transmission effect of the LED display device itself.

[0005] How to develop an LED display device that can minimize the impact on the basic functions of the carrier board, such as ventilation, while meeting the basic requirements of connection stability has become a technical problem to be solved in this field. Summary of the Invention

[0026] The remaining corners of the third through hole are right angles;

[0027] The remaining corners of the fourth through hole are right angles.

[0028] Preferably, for the LED display device,

[0029] At the said one corner of the third through hole, there are two strip structures intersecting each other;

[0030] At the said one corner of the fourth through hole, there are two strip structures intersecting each other.

[0031] Preferably, for the LED display device,

[0032] The connecting member includes at least two connecting units. The first connecting unit includes a first clip, and the second connecting unit includes a second clip.

[0033] Among them,

[0034] The first connecting unit includes an intersecting first strip-shaped structure and a second strip-shaped structure;

[0035] The second connecting unit includes an intersecting third strip-shaped structure and a fourth strip-shaped structure.

[0036] Preferably, for the LED display device described above, among them,

[0037] The first clip is arranged at the intersection of the first strip-shaped structure and the second strip-shaped structure.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the accompanying drawings in the embodiments of the present disclosure will be combined below Figures 1 to 4C to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. The components of the embodiments of the present disclosure generally described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0052] Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the claimed present disclosure, but merely represents selected embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0054] In the description of the present disclosure, it should be noted that if terms such as "upper", "lower", "inner", "outer", "row", "column", "parallel", "perpendicular", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the inventive product is usually placed during use, it is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present disclosure.

[0055] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0056] It should be noted that, without conflict, the features in the embodiments of the present disclosure can be combined with each other.

[0057] See Figure 3A and Figure 3B In one embodiment, the present disclosure discloses an LED display device, which is characterized by comprising:

[0058] A first carrier board and a second carrier board, and a connecting member for clamping the first carrier board and the second carrier board, wherein,

[0059] The first carrier board includes a first through hole and a solid area, and the solid area is used for arranging LED lamp beads;

[0060] The second carrier board includes a second through hole and a solid area, and the solid area is used for arranging LED lamp beads;

[0061] The connecting member at least includes a first clip and a second clip;

[0062] The first clip is used for clamping the first carrier board with the first through hole, and the second clip is used for clamping the second carrier board with the second through hole, so that the connecting member clamps the first carrier board and the second carrier board;

[0063] When the connecting member clamps the first carrier board and the second carrier board, the connecting member at least does not completely block the first through hole of the first carrier board, and at least does not completely block the second through hole of the second carrier board.

[0064] It should be noted that since the connecting member at least does not completely block the first through hole of the first carrier board, and at least does not completely block the second through hole of the second carrier board, the connecting member at least can not affect the basic functions and effects of the first carrier board and the second carrier board themselves. Regarding this point, in combination with Figures 4A to 4C , it can be found that Figure 3A , Figure 3BFor the specifically designed connecting member, the through-hole area thereof has a corresponding relationship with the first through-hole of the first carrier plate and the second through-hole of the second carrier plate. Therefore, the connecting member at least does not completely block the first through-hole of the first carrier plate and at least does not completely block the second through-hole of the second carrier plate.

[0065] It can be understood that the fact that the connecting member at least does not completely block the first through-hole of the first carrier plate and at least does not completely block the second through-hole of the second carrier plate can be further quantified. For example, the area of the blocked area is made less than a certain threshold of the through-hole area of the corresponding respective carrier plate.

[0066] Combined with the prior art Figure 1 shown, taking the electronic component as an LED as an example and the corresponding electronic device as an LED display device as an example, the through-hole area can also play a role of not significantly affecting the visual effect of the LED. In contrast, Figure 1 the significant thick-line area in Figure 2 has an obvious impact on the spliced carrier plate and the electronic device. Comparing with Figure 1 the first carrier plate, the second carrier plate and the connecting member in the LED display device of the present disclosure shown, it can be found that the difference between the present disclosure and the

[0067] In one embodiment, the LED display device, wherein,

[0068] the connecting member further includes a third through-hole and a fourth through-hole;

[0069] The connecting member passes through the third through-hole and the fourth through-hole so that the connecting member at least does not completely block the first through-hole and the second through-hole of the first carrier plate.

[0070] Combined with Figures 3A to 3B , and comparing with Figures 4A to 4C , it can be found that the connecting member obviously has the third through-hole and the fourth through-hole described in the above embodiment. It can be understood that Figures 4A to 4C shows two carrier plates and the circular through-holes on the two carrier plates. Therefore Figure 3A , Figure 3B only exemplifies a connecting member with a rectangular through-hole that does not completely block the corresponding circular through-hole, and the clip and the arm of the clip at a certain corner of the rectangular through-hole. Those skilled in the art should know that the carrier plate with through-holes itself may have various types of through-holes, and only need to meet the requirements pointed out in the previous embodiment: the connecting member at least does not completely block the first through-hole of the first carrier plate and at least does not completely block the second through-hole of the second carrier plate.

[0071] See Figures 3A to 3B, in one embodiment, the LED display device, wherein,

[0072] The connecting member has a front side and a back side;

[0073] The first clip and the second clip are on the same side.

[0074] Combined Figures 4A to 4C , in one embodiment,

[0075] The connecting member is located in one plane, and the first carrier board and the second carrier board are located in another plane.

[0076] That is to say, when the connecting member clamps the first carrier board and the second carrier board, the connecting member closely adheres to the plane where the first carrier board and the second carrier board are located.

[0077] , in one embodiment, the LED display device, wherein,

[0078] The connecting member includes a third through hole and a fourth through hole;

[0079] At one corner of the third through hole, one clamping arm of the first clip is provided;

[0080] At one corner of the fourth through hole, one clamping arm of the second clip is provided.

[0081] It can be understood that each clip having two clamping arms will be more firmly clamped. Figures 3A to 3B Precisely shows a clip with two clamping arms, and each tip of the clamping arm has a protrusion, so that it has a certain elasticity and can clamp the corresponding carrier board at the same time. When each clip has two clamping arms in symmetric positions, it will be more firm. At this time, preferably, the distance between the protrusions at the tips of the two clamping arms is less than the distance between the roots of the two clamping arms to more firmly hold the corresponding carrier board by the two clamping arms.

[0082] , in one embodiment, the LED display device, wherein,

[0083] The remaining corners of the third through hole are right angles;

[0084] The remaining corners of the fourth through hole are right angles.

[0085] , in one embodiment, the LED display device, wherein,

[0086] At the said one corner of the third through hole, there are two strip-shaped structures intersecting each other;

[0087] At the said one corner of the fourth through hole, there are two strip-shaped structures intersecting each other.

[0088] Typically, the intersection can be an orthogonal relationship. It can be understood that whether it is orthogonal or not does not constitute a limitation. The key lies in what is pointed out in the first embodiment above: the connecting member at least does not completely block the first through hole of the first carrier plate and at least does not completely block the second through hole of the second carrier plate. Exactly for this reason, when the force-bearing structures on the carrier plates are orthogonal strip structures, the two intersecting strip structures of the connecting member are also preferably orthogonal.

[0089] In one embodiment, the LED display device, wherein,

[0090] The connecting member includes at least two connecting units. The first connecting unit includes a first clip, and the second connecting unit includes a second clip.

[0091] Wherein,

[0092] The first connecting unit includes an intersecting first strip structure and second strip structure;

[0093] The second connecting unit includes an intersecting third strip structure and fourth strip structure.

[0094] In this way, the present disclosure can realize connecting members with different degrees of firmness by replicating two connecting units in the four directions of left, right, up, and down, so as to more firmly connect the first carrier plate and the second carrier plate.

[0095] In one embodiment, the LED display device, wherein,

[0096] The first clip is arranged at the intersection of the first strip structure and the second strip structure.

[0097] The second clip is arranged at the intersection of the third strip structure and the fourth strip structure.

[0098] In one embodiment, the LED display device, wherein,

[0099] The radial dimension of any one of the first strip structure to the fourth strip structure is smaller than the maximum outer diameter of the third through hole and the fourth through hole.

[0100] In this way, in the embodiment, on the premise of meeting the mechanical properties, the ratio of the third through hole and the fourth through hole is increased as much as possible, so as not to significantly block the through holes of the first carrier plate and the second carrier plate connected by the connecting member itself.

[0101] In one embodiment, referring to Figure 4C , the LED display device, wherein,

[0102] The connecting member has a plurality of parallel strip structures, wherein each strip structure is perpendicular to the boundary line between the first carrier plate and the second carrier plate.

[0103] It can be found thatFigure 4C Among them, the thick lines drawn from top to bottom represent the boundary line between the first carrier board and the second carrier board, because there are enlarged white or light-colored gaps at the boundary outside its through-hole area.

[0104] More particularly, as Figures 4A to 4C shown, at the boundary line between the first carrier board and the second carrier board, the connecting member has only a plurality of parallel strip-shaped structures, and the connecting member is free of any structure penetrating through the boundary line. This is obviously beneficial to the seamless splicing of multiple carrier boards.

[0105] Furthermore, for all the above embodiments, the connecting member expands to the left, right, up, and down through the stress structure in its main body area, such as the first strip-shaped structure to the fourth strip-shaped structure, etc., and each connection unit can be replicated to make the connection units symmetrical to each other, so as to achieve a more stable connection of multiple carrier boards while reducing the impact on the functions of the carrier boards themselves.

[0106] Through Figures 4A to 4C , it can be illustrated that between the two clamping arms of each clip is the non-through-hole area of the corresponding carrier board, and this area is the area on the carrier board where contacts can be set to arrange electronic components such as LEDs.

[0107] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present disclosure should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
