In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0037] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0038] like Figures 1 to 10 As shown, the present application provides a display screen, comprising a frame 20 and a light board 10, wherein the light board 10 is mounted on the frame 20. A plurality of hollow portions 111 are formed on at least a portion of the structure of the light board 10 to allow light to penetrate, so that the viewer can see the objects behind the display screen through the display screen.

[0039] In an optional embodiment, the light board 10 includes a circuit board 11 and a plurality of lamp beads 12, a plurality of hollow portions 111 are formed on at least a portion of the structure of the circuit board 11, and the circuit board 11 is provided with a plurality of lamp beads 12 at intervals along the length and width directions, each lamp bead 12 being provided with a lamp bead 12, and the hollow portion 111 is located between two adjacent lamp beads 12, which can adapt to different usage scenarios and achieve flexible and convenient use. For example, if it is installed in an outdoor environment, it can reduce the impact of strong winds on the screen and enhance the safety of the display screen; or it can be installed on a display cabinet or glass curtain wall in a shopping mall or store to avoid sunlight being blocked, and it is also convenient for viewers to see the items behind it through the display screen. In addition, air circulation and ventilation and heat dissipation effects between the lamp beads 12 can be ensured.

[0040] In an optional embodiment, the diagonal lines connecting the lamp beads 12 extend along the length or width of the circuit board 11, that is, the lamp beads 12 are arranged at a 45-degree angle relative to the circuit board 11, so that the space of the hollow portion 111 is sufficiently large, the light transmittance is better, and processing costs can also be saved. Among them, the hollow portion 111 is formed at a position where the light board 10 and the frame 20 are staggered, which not only prevents the frame 20 from blocking the light supply to the hollow portion 111, but also ensures the strength of the light board 10. That is, the portion where the light board 10 and the frame 20 overlap does not need to have a hollow portion 111, but the remaining portion except for the position of the lamp beads 12 can have a hollow portion 111.

[0041] In an optional embodiment, the display screen further includes a central control assembly. The circuit board 11 has a solid portion 112, and the central control assembly is disposed within the solid portion 112 to prevent the central control assembly from blocking the light supply from the hollow portion 111, thereby improving the light transmittance of the display screen. The hollow portion 111 is formed between the solid portions 112 to ensure the strength of the display screen.

[0042] In an optional embodiment, the physical portion 112 includes a first physical portion, a second physical portion, a third physical portion and a fourth physical portion formed around the circuit board 11, the width of the first physical portion is greater than the width of the second physical portion, the third physical portion and the fourth physical portion, and the central control component is arranged in the first physical portion.

[0043] Exemplarily, the frame 20 includes a first frame 21, a second frame 22, a third frame 23, and a fourth frame 24. The width of the first frame 21 is greater than the widths of the second frame 22, the third frame 23, and the fourth frame 24. The first physical portion is mounted on the first frame 21, the second physical portion is mounted on the second frame 22, the third physical portion is mounted on the third frame 23, and the fourth physical portion is mounted on the fourth frame 24. The central control assembly is disposed within the first frame 21. When the display screen is installed, the first frame 21 is located at the lower end of the display screen, the second frame 22 is located at the upper end of the display screen, and the third frame 23 and the fourth frame 24 are located at the left and right ends of the display screen. This means that the physical portion 112 of the light board 10 at the bottom is wider, while the physical portions 112 at the ends and the upper end of the light board 10 are thinner, resulting in better light transmittance. Typically, the light transmittance of a display screen can be as high as 52%.

[0044] In an optional embodiment, the light board 10 includes a horizontal bar structure 13 , which is used to enhance the strength of the light board 10 .

[0046] In an optional embodiment, the display screen also includes a connector 30 having a snap-on structure 321 that is compatible with the hollow portion 111, so that the circuit board 11 is snapped onto the connector 30 to achieve splicing between the light panels 10 or fix the light panels 10 on the frame 20; at the same time, the snap-on connection method makes it not only convenient to disassemble but also reusable.

[0047] For example, two adjacent circuit boards 11 are connected by a connector 30, wherein the snap structure 321 is snapped into the hollow portion 111 on one side of the horizontal bar structure 13. Alternatively, the connector 30 is fixed to the frame 20, and the circuit boards 11 are fixed to the frame 20 by snapping with the snap structure 321, which not only facilitates disassembly but also allows for reuse.

[0048] In an optional embodiment, the connecting member 30 includes a connecting plate 31 and a first fixing member 32, a snap-fit ​​structure 321 is formed on the first fixing member 32, and the first fixing member 32 is arranged on the connecting plate 31 so that the hollow portions 111 of two adjacent circuit boards 11 can be snapped onto the first fixing member 32, thereby being fixed together through the connecting plate 31; alternatively, the connecting plate 31 can be fixed to the frame 20, so that the circuit board 11 can be fixed to the frame 20 by snapping onto the first fixing member 32.

[0049] In an optional embodiment, the connector 30 includes a second fixing member 33, and the connecting plate 31 is fixed to the frame 20 via the second fixing member 33, so that the circuit board 11 can be fixed to the frame 20 via the connector 30. This not only facilitates installation and improves assembly efficiency, but also facilitates subsequent maintenance of the display screen.

[0050] In an optional embodiment, there are at least two first fixing members 32 and second fixing members 33, so that one first fixing member 32 can be connected to the hollow portion 111 of one circuit board 11, and the other first fixing member 32 can be connected to the hollow portion 111 of the other circuit board 11, thereby achieving splicing between the two circuit boards 11. The second fixing member 33 is connected to two adjacent frames 20, so that the circuit boards 11 can be fixed to the frames 20 and / or the horizontal strip structure 13 through the connecting members 30.

[0051] In an optional embodiment, the number of the first fixing members 32 is four, and two of the four first fixing members 32 are symmetrically arranged relative to the central axis of the connecting plate 31 , and the second fixing member 33 is arranged between two adjacent first fixing members 32 .

[0052] In an optional embodiment, a first connecting hole 311 and a second connecting hole 312 are provided on the connecting plate 31, the first fixing member 32 is snapped into the first connecting hole 311, and the second fixing member 33 passes through the second connecting hole 312 and is connected to the frame 20 and / or the cross bar structure 13.

[0053] In an optional embodiment, the plurality of hollow portions 111 are spaced apart from each other.

[0054] In an optional embodiment, the multiple hollow portions 111 are interconnected.

[0055] In an optional embodiment, the color of the connector 30 is gray and the color of the light panel 10 is black, so as to enhance the display effect of the display screen and prevent the connector 30 from affecting the transmittance of the display screen.
