Technical Field

[0001] The utility model relates to the technical field of LED display, in particular to an LED display carrier board and a display device. Background Art

[0002] The technical solution relates to a transparent LED display device, such as an LED transparent screen. The common LED transparent screen in the prior art is an LED line screen, which is composed of LED display strips arranged in rows and a supporting component. The prior art also discloses a perforated LED transparent screen, such as patent CN114863868B discloses an LED carrier board and a display device thereof, which can realize LED transparent display. However, in order to achieve a better transparent display effect, the perforated transparent screen often has a small spacing between holes, and the wiring space is also small, which limits the overcurrent capacity of the line, which leads to the attenuation of the far-end voltage of the transparent screen, thereby showing uneven color and brightness, so this aspect also limits the realization of the large transparent screen solution.

[0003] In addition, the RGB arrangement of two adjacent lamp beads in the wiring structure of the prior art is inconsistent (such as Fig.13 ), this inconsistency will inevitably lead to inconsistent color display of the lamp beads, and the human eye can easily recognize this display inconsistency, so the wiring structure in the prior art has a greater impact on the visual effect.

DETAILED DESCRIPTION

[0039] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0040] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, the omission of some well-known structures and their descriptions in the drawings is understandable. The same or similar reference numerals correspond to the same or similar parts.

[0041] There are many solutions for realizing LED transparent screens in the prior art, such as line screens, grid screens, etc. Patent CN114863868B discloses a perforated LED carrier screen, that is, transparent holes are punched regularly on a whole PCB board, LED illuminants are arranged in the solid area, and the LED carrier, LED illuminants and controller constitute a complete LED transparent screen, thereby achieving a transparent visual effect.

[0042] However, according to PCB process standards, there are limit standards for the thickness of PCB circuits. For example, the standard design specification for printed circuit boards IPC-2152 issued by the International Association for Printed Circuits (IPC) stipulates that the thickness range of the inner copper foil (copper cladding) is 0.5-4oz (oz is ounce, 1oz equals 35μm), and the thickness range of the outer copper foil (copper cladding) is 0.5-6oz. In other words, the design range of the thickness of the inner copper foil (copper cladding) is 0.17-140μm, and the design range of the thickness of the outer copper foil (copper cladding) is 0.17-210μm. In the prior art, the commonly used thicknesses of copper foil (copper cladding) are 35μm, 50μm, and 70μm.

[0043] Therefore, it is difficult for PCB lines to achieve high current transmission at this standard thickness. If the LED transparent screen made of PCB LED substrate is too large, the remote LED light source will be insufficiently powered, resulting in unbalanced overall color and brightness of the LED transparent screen, which limits the development of large-area LED transparent screens.

[0044] Based on the deficiencies of the prior art, the utility model provides a brand-new technical solution to solve the above-mentioned technical problems. The back of the LED display carrier recorded in the technical solution is provided with a reinforced conductive part for enhancing the overcurrent capability, and the reinforced conductive part is electrically connected to the corresponding VDD power supply line and GND, thereby significantly enhancing the overcurrent capability of the VDD power supply line and the GND line. However, the data signal line that does not require high overcurrent capability is not changed. Due to the brand-new structure of the technical solution, the reinforced conductive part successfully solves the overcurrent problem of the PCB, thereby greatly expanding the overcurrent capability of the VDD power supply line and the GND line. This improvement increases the single-sided power supply length of the LED display carrier, and provides hardware support for large-scale LED transparent screens.

[0045] The embodiments of the present utility model are as follows: Example 1

[0046] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, an LED display carrier includes an LED display carrier 1 and a reinforced conductive portion. The LED display carrier 1 is composed of a plurality of carrier units 100 .

[0047] It should be pointed out that the LED display carrier 1 is a whole, which can be divided into multiple carrier units 100. This division can be either a virtual unit divided on a complete LED display carrier 1, or there can be a real physical connection relationship between multiple carrier units 100, but it should not be understood that the carrier unit 100 is a completely independent individual.

[0048] In the present technical solution, the boundary of the LED display carrier 1 is composed of the boundary arrangement of multiple carrier units 100, so the splicing effect of the joint of two LED display carriers 1 is the same as the effect of the joint of two carrier units 100, both have no sense of boundary and can form a perfect whole, so the LED display carrier 1 is scalable.

[0049] In this embodiment, Figure 1 As shown, the carrier unit 100 comprises a hollow area 111 and a solid area 12 . When a plurality of the carrier units 100 are combined, the hollow areas 111 at corresponding positions of adjacent carrier units 100 can be combined to form a complete through hole 11 .

[0050] In the drawings related to the LED display carrier 1, the dotted lines around the carrier unit 100, the dotted lines adjacent to the carrier unit 100, and the lines adjacent to the physical area 12 in the same LED carrier are displayed for a better understanding of the present technical solution.

[0051] It should be noted that the carrier unit 100 includes a hollow area 111 and a solid area 12. The carrier unit 100 is a subdivided unit of the LED display carrier 1. The four corners of the carrier unit 100 are hollow areas 111. The intersection of the extension lines of the longitudinal straight edge and the transverse straight edge of the carrier unit 100 is the center point of the through hole 11. The center point of the through hole 11 is connected with the longitudinal straight edge and the transverse straight edge of the carrier unit 100 to form a hollow area 111. Figure 1 and Figure 4 The carrier unit in this embodiment is square, and the square carrier unit is easier to understand the technical solution.

[0052] In this technical solution, no matter what the shape of the through hole 11 is, a hollow area 111 can be formed by connecting the center point of each through hole 11 with the longitudinal straight edge and the transverse straight edge of the carrier unit 100, and the carrier units can be spliced. After splicing, the through hole is composed of the hollow areas 111 at the corresponding positions of the adjacent carrier units. It should be noted that in this embodiment, the division method of the carrier unit is intended to more accurately explain the technical solution. Although the division of the carrier unit varies in different scenarios, they are actually still regarded as the same technical solution.

[0053] The utility model is a technical solution based on a transparent or translucent LED display carrier. The LED display screen based on the LED display carrier can display images and present a transparent visual effect, and the regularly arranged through holes 11 play the role of the transparent visual effect. Since the technical solution uses a large number of LED illuminants (or LED lamp beads), the heat generation problem is a technical problem that is difficult to overcome in the entire industry. These regularly arranged through holes 11 can solve the two major problems of ventilation and heat dissipation at the same time.

[0054] When not working, natural light can pass through the multiple through holes 11 to form a display screen with a certain light transmittance. Under natural light conditions, the amount of light transmittance is related to the aperture size and density of the through holes 11. The larger the aperture and the higher the density of the through holes 11, the more light transmittance there is, and the closer to a transparent visual effect. The farther the viewing distance, the better the transparent visual effect.

[0055] It should be pointed out that the present technical solution does not limit the specific shape of the through hole 11 , and round holes, elliptical holes, square holes, irregular holes, etc. can all achieve the above-mentioned technical effects.

[0056] In this embodiment, Figure 2 , Figure 6 and Figure 7As shown, the back side of the carrier unit entity area 12 is provided with a first type of sub-connection line 211, and a plurality of the first type of sub-connection lines 211 are combined and connected to form a first type of connection line 21, and a plurality of the carrier units 100 are arranged and combined to form a sub-LED display carrier 10 (such as Figure 5 , Figure 7 and Fig. 9 As shown), a plurality of sub-LED display carrier boards 10 are arranged to form the LED display carrier board 1.

[0057] It should be pointed out that Figure 2 There are two first-type sub-connection lines 211 shown in FIG. 2, namely, 211a and 211b, and 211a and 211b are sub-VDD power supply line and sub-GND line respectively. The combination of 211a and 211b is turned on, which means that the first-type sub-connection line 211 is turned on. The first-type sub-connection line 211 after the combination is turned on is the first-type connection line 21, Figure 6 and Figure 7 The first type of connection line 21 in the embodiment is the state after the first type of sub-connection lines 211 are combined and turned on. In this embodiment, the first type of connection line 21 includes a VDD power supply line and a GND line (described below).

[0058] In this embodiment, the front side of the carrier unit entity area 12 is used to set the LED light source 3, as shown in FIG. Figure 3 and Figure 8 The LED illuminator 3 in this embodiment includes an LED driver chip and R-color lamp beads (red), G-color lamp beads (green) and B-color lamp beads (blue). The LED illuminator 3 presents the required color after dimming and fusion of the driving signals of the three-color lamp beads of B, G and R.

[0059] In this embodiment, the data signal may be transmitted through the first type connection line 21 in the form of a carrier.

[0060] In another embodiment, the LED display carrier board may be provided with a separate data signal line. Figure 3 and Figure 8 As shown, a second-type sub-connection line 221 is set on the front side of the carrier unit physical area 12, and multiple second-type sub-connection lines 221 are combined and conducted to form a second-type connection line 22. Multiple carrier units 100 are arranged and combined to form a sub-LED display carrier 10 with the second-type connection line 22 conducting, and multiple sub-LED display carriers 10 are arranged to form the LED display carrier 1.

[0061] Figure 8 and Fig. 9 FIG. 2 shows a situation where the second-type sub-connection lines 221 are combined and conducted to form the second-type connection lines 22 , and the second-type connection lines 22 are data signal lines.

[0062] In the same LED display carrier board 1 , the first type of connection lines 21 and the second type of connection lines 22 are both smooth and complete connection lines. This embodiment is described in the form of a combination of multiple sub-connection lines only for the convenience of description.

[0063] In this embodiment, the enhanced conductive portion is disposed on the first-type connecting wire 21 and electrically connected thereto, so as to enhance the overcurrent capability of the first-type connecting wire 21 .

[0064] The technical problem solved by strengthening the conductive part is to improve the overcurrent capacity of the VDD power supply line and the GND line. The conventional technical solution is to thicken the VDD power supply line and the GND line. However, due to the limitation of the PCB board process standard, even if the values ​​of the VDD power supply line and the GND line reach the limit value of the PCB board, it still cannot meet the demand when the single-ended power supply is long (more than 3 meters). Therefore, other technical solutions need to be adopted to achieve this goal. This technical solution solves the above technical problems.

[0065] In another embodiment, the LED display carrier 1 further includes a cover 30, and the cover 30 covers the enhanced conductive portion on the back of the LED display carrier 1. Fig.11 and Fig.12 The cover 30 has a protective effect on the enhanced conductive part, and can improve the working stability of the LED display carrier 1.

[0066] The cover body 30 in this embodiment is preferably made of non-metallic insulating material, but it is not excluded that the cover body 30 is made of metal material, especially a metal material with good insulation protection.

[0067] In order to solve the problem of outdoor humid and rainy application environment, the insulating glue 34 is filled between the reinforced conductive part and the cover 30 in this embodiment. The filling of the insulating glue 34 makes the LED display carrier board have a strong waterproof function. In addition, the insulating glue 34 also has the effect of enhancing the insulation between the reinforced conductive parts and between the reinforced conductive parts and the cover 30.

[0068] In this embodiment, the first sub-type connection line 211 includes a sub-VDD power supply line and a sub-GND line. A plurality of the sub-VDD power supply lines 211a are combined and connected to form a VDD power supply line 211a, and a plurality of the sub-GND lines 211b are combined and connected to form a GND line 211b. Figure 6 and 7 shown.

[0069] In this embodiment, the VDD power supply line and the GND line are each provided with the enhanced conductive portion 31 and electrically connected thereto. Fig.11 shown.

[0070] The reinforced conductive part 31 in this embodiment is preferably made of thick copper, preferably with a thickness of 0.22mm-1.60mm, and is fitted and covered on the VDD power supply line and the GND line, which greatly increases the overcurrent capacity of the VDD power supply line and the GND line, and the brightness index of the LED light-emitting body at the power supply end of the LED display carrier 1 is significantly increased. It should be pointed out that because the VDD power supply line and the GND line themselves have a certain thickness and overcurrent capacity, considering these factors of the VDD power supply line and the GND line themselves, the thickness of the reinforced conductive part 31 can be less than 0.22mm under the condition of meeting the preset value of the overcurrent target.

[0071] like Fig.10 As shown, the reinforcing conductive portion 31 is attached to the VDD power supply line and the GND line and is electrically connected thereto.

[0072] In this embodiment, the enhanced conductive portion 31 is connected to the VDD power supply line and the GND line in the following ways:

[0073] The first type: the bonding parts of the strengthening conductive part 31 and the VDD power supply line and the GND line are all electrically connected. In this case, the current in each part of the VDD power supply line and the GND line is strengthened and uniform.

[0074] The second type: the enhanced conductive part 31 is connected to the VDD power supply line and the GND line at the ends, and the middle part is not connected to the VDD power supply line and the GND line. In this case, the current at both ends of the VDD power supply line and the GND line is enhanced to the maximum, and the current at both ends gradually decreases toward the middle, and the current uniformity of the entire VDD power supply line and the GND line is poor.

[0075] The third method is to strengthen the conductive part 31 and connect the VDD power supply line and the GND line at the beginning and end, and select a few points in the middle to connect with the VDD power supply line and the GND line, and do not connect with other places. In this case, the current of all the conducting points can be strengthened and the uniformity is good.

[0076] The fourth type: the enhanced conductive part 31 on the VDD power supply line and the GND line is not a whole, but is composed of multiple segmented sub-enhanced conductive parts, and the sub-enhanced conductive parts are evenly spaced and arranged on the VDD power supply line and the GND line, and are electrically connected to the parts where the VDD power supply line and the GND line are attached. This situation can improve the overcurrent capacity of the VDD power supply line and the GND line, but the effect is worse than the first and third situations.

[0077] In this embodiment, the first connection method is preferably used for the enhanced conductive portion 31 and the VDD power supply line and the GND line.

[0078] It should be noted that the LED display carrier board 1 in this embodiment is a PCB board, and the VDD power supply line and the GND line are wiring on the PCB board. The exposed parts of the VDD power supply line and the GND line are not insulated, so that it is convenient to electrically connect and fit with the enhanced conductive part 31. The VDD power supply line, the GND line and the enhanced conductive part 31 are preferably connected by brushing solder.

[0079] It should be noted in this embodiment that, except for the position where the reinforcing conductive part 31 contacts the VDD power supply line and the GND line, the rest of the part is provided with an insulating layer or painted with insulating paint.

[0080] In this embodiment, Figure 3 , Figure 8 and Fig. 9 As shown, the front side of the carrier unit physical area 12 is also provided with a first electrode pin 41, a second electrode pin 42 and a third electrode pin 43. Specifically, the first electrode pin 41 is electrically connected to the VDD power supply line, the second electrode pin 42 is electrically connected to the GND line, and the third electrode pin 43 is electrically connected to the data signal line.

[0081] It should be pointed out that, in this embodiment, the first electrode pin 41 , the second electrode pin 42 and the third electrode pin 43 are used to fix the LED light-emitting body 3 and provide power and data signals to the LED light-emitting body 3 .

[0082] In one embodiment, the first electrode pin 41 is electrically connected to the VDD power supply line on the back of the carrier unit physical area 12 by penetrating the first branch line 411 of the carrier unit physical area 12, the second electrode pin 42 is electrically connected to the GND line on the back of the carrier unit physical area 12 by penetrating the second branch line 421 of the carrier unit physical area 12, and the third electrode pin 43 is directly arranged on the data signal line (on the second type connection line 22) on the front of the carrier unit physical area 12, as shown in FIG. Fig.10 shown. Example 2

[0083] The difference between this embodiment and the first embodiment is that the carrier unit includes a first carrier unit and a second carrier unit, and a third branch line and a fourth branch line structure are disposed on the LED display carrier.

[0084] The technical problem solved by this embodiment is the problem of inconsistent RGB arrangement of two adjacent lamp beads in the LED transparent screen in the prior art, or the problem that the LED transparent screen in the prior art requires LED lamp beads of multiple specifications. The above problems not only lead to poor visual effects of the display screen, but also cause the production process of the display screen to be complicated and the cost to increase (at least two types of lamp beads must be produced: A lamp bead and B lamp bead. And when mounting the lamp beads, it is very easy to make a mistake between A lamp bead and B lamp bead).

[0085] In the prior art, LED illuminators or LED lamp beads are usually composed of an LED driver chip, three types of lamp beads, R (red), G (green) and B (blue). Fig.13 As shown, GND is the GND line, VDD is the VDD power supply line, LED illuminator 71 (A lamp bead) and LED illuminator 72 (B lamp bead) are two kinds of LED illuminators with different RGB arrangements. In common application scenarios, due to the limitations of the wiring structure (such as Fig.13 As shown in ), two types of LED illuminants are usually required in the LED display carrier, namely LED illuminant 71 and LED illuminant 72, wherein the interior of LED illuminant 71 is R, G and B lamp beads from left to right, and the interior of LED illuminant 72 is B, G and R lamp beads from left to right, that is, the arrangement of the lamp beads inside LED illuminant 71 and LED illuminant 72 is different. It can be understood by those skilled in the art that the color presented by the LED illuminant is the color after the RGB three-color lamp beads are dimmed by the driving signal. When the physical position of the RGB three-color lamp beads inside the LED illuminant changes, the color presented by the dimming under the same driving signal will have a certain deviation. Therefore, due to the different arrangement of the lamp beads inside the above-mentioned LED illuminants, the display effects of the two illuminants in actual applications are also different. This leads to poor color consistency of the entire LED display device, and the human eye can easily see this deviation, so it is difficult to achieve ideal color reproduction in this way.

[0086] This embodiment only requires one specification of LED luminous body, and solves the above technical problems through the special wiring structure formed by the first type of connecting wire 21 and / or the second type of connecting wire 22, and the third branch wire and the fourth branch wire to be introduced below.

[0087] The present embodiment is as follows:

[0088] The present embodiment provides an LED display carrier, including a reinforcing conductive portion 31 . The LED display carrier 1 is composed of a plurality of carrier units 100 . The carrier unit 100 includes a first carrier unit 100 a and a second carrier unit 100 b .
