Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0022] In one embodiment, Figure 1 and Figure 2As shown, the embodiment of the present application provides a transparent LED display screen 1, which includes a profile frame 100, a lamp board assembly 200 and a control assembly 300. The control assembly 300 is hidden in the profile frame 100, and the control assembly 300 is connected to the lamp board assembly 200 for driving. The lamp board assembly 200 includes at least one lamp board 210, and the lamp board 210 includes a hollow PCB board body 211, a plurality of LED lamp beads 212 and a plurality of driver ICs 213. The plurality of LED lamp beads 212 are distributed in a matrix on the first surface of the hollow PCB board body 211, so that each four LED lamp beads 212 adjacent in the vertical and horizontal directions are surrounded to form a rectangular area. In each of the two adjacent rectangular areas in the vertical direction, one rectangular area is hollowed out to provide a first opening 214 extending in the longitudinal direction, and the other rectangular area is hollowed out to provide a second opening 215, and the opening size of the second opening 215 is smaller than the opening size of the first opening 214. A plurality of driving ICs 213 are evenly distributed on the second surface of the hollow PCB body 211 , and each driving IC 213 is disposed away from each first opening 214 and each second opening 215 .

[0023] It is understandable that the transparent LED display screen 100 of the embodiment of the present application is mainly used to display content through itself, while allowing the scenery behind it to be visible, so that the audience can see the scenery behind the screen to increase the visual effect and sense of space. In order to realize the transparent content display control of the light board assembly 200 and to power its operation as a whole, the control assembly 300 includes, in addition to the receiving control card 310, a card board 320 for realizing its driving connection with the light board assembly 200, and a power supply module 330 for powering all electrical components on the transparent LED display screen 100. The card board 320 can mainly realize the electrical connection between it and the receiving control card 310 or one end of each light board 210 by matching the connecting pins and the connecting mothers.

[0024] In addition, the horizontal direction mentioned in the embodiment of the present application mainly refers to the width direction of the hollow PCB body 211, and the vertical direction mainly refers to the length direction of the hollow PCB body 211. The LED lamp beads 212 generally use RGB full-color lamp beads with universal 1221, 1415, and 1921 packages, while the driver IC 213 generally uses conventional packaged driver chips such as GFN (1*2MM; 2*3MM; 3*4MM). In addition, the circuit design of each lamp board assembly 200 can specifically use a driver chip with 18 channels or 16 channels to carry multiple RGB lamp beads in a column direction, and perform a cascade design in a horizontal scanning mode at the same time, which can better adapt to a variety of application scenarios.

[0025] In this way, the transparent LED display screen 1 of the embodiment of the present application, through the large and small hole design formed by the staggered first opening 214 and the second opening 215, combined with the evenly distributed device layout of a plurality of LED lamp beads 212 and a plurality of driver ICs 213, can maximize the hollowing rate of the lamp board 210, thereby effectively improving its transparent display effect.

[0026] In some examples, such as Figure 1 and Figure 2 As shown, the first opening 214 is formed by two first circular holes 2141 and one second circular hole 2142 connected to each other, and the two first circular holes 2141 are respectively connected to two opposite sides of the second circular hole 2142 in the longitudinal direction, and the diameter of the second circular hole 2142 is greater than the diameter of the first circular hole. In this way, a maximized circle can be completed by drilling three holes of two first circular holes 2141 and one second circular hole 2142, that is, the first opening 214 can maximize the use of the gap space of the corresponding rectangular area without affecting the design of the second opening 215 of another rectangular area adjacent to the longitudinal direction, so that the hollowing rate of the lamp board 210 can be maximized and the process cost can be saved.

[0027] In some examples, such as Figure 1 and Figure 2 As shown, the center of the second circular hole 2142 is located at the center of the corresponding rectangular area, and the diameter of the second circular hole 2142 is greater than the first distance and less than the second distance. The first distance is the distance between two LED lamp beads 212 that are adjacent to each other in the corresponding rectangular area, and the second distance is the distance between two LED lamp beads 212 that are diagonally arranged in the corresponding rectangular area. In this way, the above-mentioned structure can be set so that the opening area of ​​the second circular hole 2142 can utilize the gap space in the central part of the corresponding rectangular area as much as possible to further improve the hollowing rate of the lamp board 210. Furthermore, the center of the first circular hole 2141 is located at the center of the preset lamp bead connection line, and the diameter of the first circular hole 2141 is less than the first distance. The first distance is the distance between two LED lamp beads 212 that are adjacent to each other in the corresponding rectangular area, and the preset lamp bead connection line is the center connection line between two LED lamp beads 212 that are adjacent to each other in the corresponding rectangular area. In this way, the above-mentioned structure can be set so that the opening area of ​​the second circular hole 2142 can make use of the gap between two horizontally adjacent LED lamp beads 212 as much as possible to match the corresponding second circular hole 2142, so that the opening area of ​​the corresponding first opening 214 is maximized, thereby further improving the hollowing rate of the lamp board 210. Furthermore, the difference between the first distance and the diameter of the first circular hole 2141 is 0.1mm to 0.2mm. In this way, the setting of this difference can maximize the opening of the first circular hole 2141 without affecting the normal setting of the LED lamp beads 212 on both sides.

[0028] In some examples, such as Figure 1 and Figure 2 As shown, the second opening 215 is a third circular hole, the center of the third circular hole is located at the center of the preset lamp bead connection line, and the diameter of the third circular hole is smaller than the first distance, the first distance is the distance between two LED lamp beads 212 adjacent to each other in the corresponding rectangular area, and the preset lamp bead connection line is the center connection line between two LED lamp beads 212 adjacent to each other in the corresponding rectangular area. In this way, the above-mentioned structure can be set so that the opening area of ​​the third circular hole can make use of the gap between two LED lamp beads 212 adjacent to each other as much as possible, while not affecting the maximized design of the adjacent first opening 214, so as to maximize the hollowing rate of the lamp board 210. Furthermore, the difference between the first distance and the diameter of the third circular hole is 0.1mm to 0.2mm. In this way, the setting of this difference can be used to maximize the opening of the third circular hole while not affecting the normal setting of the LED lamp beads 212 on both sides.

[0029] In some examples, such as Figure 1 and Figure 2 As shown, the light board assembly 200 includes two or more light boards 210, and two light boards 210 adjacent to each other in the horizontal direction are spliced ​​and connected by at least one light board connector 220, and one end of each light board 210 is connected to the control assembly 300 (specifically, a receiving control card 310) through a card board 320. In this way, the board-to-board connection between at least two light boards 210 can be achieved through the structural setting of the light board connector 220, that is, by splicing the light boards 210 in width, the requirements for more display sizes of the transparent LED display screen can be met.

[0030] It is understandable that the lamp board connector 220 should be provided with a lamp bead avoidance hole 221 to avoid the LED lamp beads 212 at the corresponding position when realizing the board-to-board connection between the two lamp boards 210, so as not to affect the display effect.

[0031] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the utility model concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
