[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Combination Figures 1 to 6The diagram schematically illustrates the light-transmitting display device of this invention, including a splicing component 10 and multiple display circuit boards 20. The splicing component 10 can be a thin plate structure or other shapes, preferably made of metal, but can also be made of other materials, such as glass or plastic. The display circuit boards 20 have a front side 20a and a back side 20b. The front side 20a of the display circuit board 20 is provided with multiple display units 22 arranged in a matrix. The display units 22 can be LED beads, including multiple LED light-emitting chips with different emitting colors. Adjusting the brightness ratio of each LED light-emitting chip in the display unit 22 can change the color of the display unit 22. The splicing component 10 is located on the back side 20b of the display circuit board 20 and the two are parallel to each other. The splicing component 10 and the display units 22 are respectively arranged on opposite sides of the display circuit board 20 to avoid structural interference between the splicing component 10 and the display units 22.

[0034] like Figure 4 The splicing component 10 is provided with an installation assembly 30. The installation assembly 30 includes a plurality of clearance holes 31 formed on the splicing component 10. The clearance holes 31 are provided with snap-fit ​​components 32 on their sides. The clearance holes 31 and snap-fit ​​components 32 in the installation assembly 30 are both arranged along the first direction X. That is, the plurality of clearance holes 31 in the installation assembly 30 are arranged along the first direction X, and the snap-fit ​​components 32 in the installation assembly 30 are also arranged along the first direction X.

[0035] like Figure 1 and Figure 2 The display circuit board 20 has multiple light-transmitting holes 21 arranged in a matrix. The display unit 22 is staggered from the light-transmitting holes 21, meaning the display unit 22 is located outside the area of ​​the light-transmitting holes 21. Each light-transmitting hole 21 is connected to a corresponding clearance hole 31. A snap-fit ​​component 32 snaps into the hole wall of the light-transmitting hole 21. Multiple display circuit boards 20 are spliced ​​together by a splicing component 10. The clearance hole 31 can communicate with the light-transmitting holes 21 on the display circuit board 20 to prevent the splicing component 10 from blocking the light-transmitting holes 21 on the display circuit board 20 and affecting the light transmission performance. The snap-fit ​​component 32 can snap into the light-transmitting holes 21 on the display circuit board 20 to connect the splicing component 10 to the display circuit board 20. Multiple display circuit boards 20 are spliced ​​on the same splicing component 10, realizing the splicing of multiple display circuit boards 20.

[0036] In this embodiment, combined with Figure 3 and Figure 4As shown, there are multiple mounting components 30 arranged along the second direction Y. The first direction X and the second direction Y are perpendicular. The first direction X can be horizontal, and the second direction Y can be vertical. All the clearance holes 31 on the splicing component 10 are arranged in a matrix, and the positions of the clearance holes 31 correspond one-to-one with the positions of the light-transmitting holes 21 on the display circuit board 20. The snap-fit ​​parts 32 of two adjacent mounting components 30 are oriented in opposite directions. The display circuit board 20 spliced ​​with the splicing component 10 is spliced ​​with at least two snap-fit ​​parts 32 of the mounting components 30. Therefore, the snap-fit ​​parts 32 of at least two mounting components 30 on the splicing component 10 are respectively snapped onto different sides of the corresponding light-transmitting holes 21, thereby restricting the degree of freedom between the splicing component 10 and the display circuit board 20. For example, the light-transmitting hole 21 of the display circuit board 20 is a circular hole. The two oppositely arranged diameter points of the light-transmitting hole 21 are the first diameter point and the second diameter point, respectively. The line connecting the first diameter point and the second diameter point is the diameter of the light-transmitting hole 21. The snap-fit ​​component 32 in one of the mounting components 30 on the splicing piece 10 snaps into the first diameter point of one of the light-transmitting holes 21, and the snap-fit ​​component 32 in the other mounting component 30 snaps into the second diameter point of the other light-transmitting hole 21.

[0037] Specifically, the opening area of ​​the clearance hole 31 is larger than that of the light-transmitting hole 21, and the hole axis of the light-transmitting hole 21 can coincide with the hole axis of the clearance hole 31. The outer contour of the projection of the light-transmitting hole 21 on the splicing component 10 is located inside the clearance hole 31. The snap-fit ​​component 32 has a head end 32a and a tail end 32b. The tail end 32b of the snap-fit ​​component 32 is provided with an extension block 323 extending toward the inner wall surface of the clearance hole 31. The extension block 323 is connected to the side of the clearance hole 31. The setting of the extension block 323 makes the snap-fit ​​component 32 closer to the center of the clearance hole 31, so that the opening area of ​​the clearance hole 31 can be set to be larger. This can prevent the edge or inner wall of the clearance hole 31 from blocking the light or airflow passing through the light-transmitting hole 21.

[0038] Furthermore, such as Figure 6 The first end 32a of the snap-fit ​​component 32 is provided with a lever 321, and a limiting groove 322 is provided between the first end 32a and the last end 32b of the snap-fit ​​component 32. The first end 32a of the snap-fit ​​component 32 passes through the light-transmitting hole 21, and the lever 321 is located on the front side 20a of the display circuit board 20. The limiting groove 322 can snap onto the edge of the light-transmitting hole 21. When the installation and maintenance personnel apply force to pull the lever 321 at the first end 32a of the snap-fit ​​component 32, the snap-fit ​​component 32 can be deformed, and the limiting groove 322 can be separated from the edge of the light-transmitting hole 21. Thus, the snap-fit ​​component 32 can be separated from the light-transmitting hole 21, thereby separating the splicing piece 10 and the display circuit board 20.

[0039] The cross-section of the snap-fit ​​component 32 is arc-shaped, for example, C-shaped, and its opening is arranged towards the center of the clearance hole 31. That is, the projection of the snap-fit ​​component 32 on the splicing component 10 is roughly C-shaped. When the light-transmitting hole 21 of the display circuit board 20 is a round hole, the outline of the outer arc surface of the snap-fit ​​component 32 can fit the inner wall surface of the light-transmitting hole 21, and the contact area between the snap-fit ​​component 32 and the light-transmitting hole 21 is increased, so as to prevent the snap-fit ​​component 32 from scratching or tearing the inner wall surface of the light-transmitting hole 21.

[0040] In this embodiment, the opening shape of the clearance hole 31 is a rounded rectangle. The rounded corners can prevent stress concentration and tearing at the corners of the clearance hole 31. The extension block 323 of the tail end 32b of the snap-fit ​​component 32 is connected to one side of the clearance hole 31.

[0041] In practical applications, two adjacent display circuit boards 20 can be spliced ​​together by a splicing component 10. The light-transmitting hole 21 of one display circuit board 20 is engaged with the locking component 32 at one end of the splicing component 10, and the light-transmitting hole 21 of the other display circuit board 20 is engaged with the locking component 32 at the other end of the splicing component 10. By splicing the two display circuit boards 20 together through the splicing component 10, the clearance hole 31 on the splicing component 10 can be connected to the light-transmitting hole 21 on the display circuit board 20. The splicing component 10 will not block the light-transmitting hole 21 on the display circuit board 20 and affect the light transmission performance, thus avoiding the formation of black blocks between two adjacent display circuit boards 20.

[0042] In summary, the display circuit board 20 has multiple light-transmitting holes 21, and the mounting components 30 on the splicing piece 10 have multiple clearance holes 31. The clearance holes 31 can be connected to the light-transmitting holes 21 on the display circuit board 20 to prevent the splicing piece 10 from blocking the light-transmitting holes 21 on the display circuit board 20 and affecting the light transmission performance. The snap-fit ​​component 32 and the clearance holes 31 are both arranged along the first direction X. The snap-fit ​​component 32 is used to pass through the light-transmitting hole 21 and snap onto the hole wall of the light-transmitting hole 21. Multiple display circuit boards 20 are spliced ​​together by the splicing piece 10 to connect the multiple display circuit boards 20 into one, forming a larger area transparent display screen.
