[0002] With the continuous development of technology, LED display screens, with features such as seamless splicing and excellent color restoration, are currently used not only in billboards, conference rooms, high-speed railway stations and other scenarios, but also in stages, exhibition halls, studios and other places. As the application fields of LED display screens become more and more extensive, LED display screen manufacturers have also started to enter cinemas and theaters.

[0003] The application of LED display screens is becoming more and more extensive. For different application occasions, there are often different requirements. For the occasion of cinemas and theaters, in addition to meeting the display standards of cinemas, cinemas also have relatively high requirements for the quality of sound, so as to ensure that the audience has an immersive audio-visual experience. Different from traditional projectors, the screens of projectors have a relatively high sound transmission rate and can easily meet the sound standard requirements of cinemas. LED cinema screens are usually assembled from printed circuit boards. In actual applications, when using LED display screens in cinemas, due to the low sound transmission rate of the screen body, the sound effect cannot meet the requirements.

[0018] To facilitate the understanding of the present utility model, the present utility model will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that when an element is expressed as "communicating with" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is expressed as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are only for the purpose of illustration.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in this specification in the description of the utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0020] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Please refer to Figures 1 to 3 , one embodiment of the present utility model provides a sound-transmitting LED display module 1, which includes a bottom case (not shown in the figure), a sound-transmitting LED display board 100, and a drive control board 200. Sound-transmitting holes 101 are formed on the sound-transmitting LED display board 100. The drive control board 200 is welded to the back of the sound-transmitting LED display board 100. The sound-transmitting LED display board 100 and the drive control board 200 are installed in the bottom case. By separating the display circuit and the drive circuit and forming sound-transmitting holes on the sound-transmitting LED display board, the sound-transmitting rate can be improved and the sound effect can be ensured.

[0022] In some embodiments, as Figure 1 shown, LED lamp beads 102 are provided on the sound-transmitting LED display board 100. The LED lamp beads 102 are arranged at equal intervals on the sound-transmitting LED display board 100. Longitudinal strip-shaped sound-transmitting holes 101 are formed longitudinally on the sound-transmitting LED display board 100. In other embodiments, strip-shaped sound-transmitting holes are formed transversely on the sound-transmitting LED display board 100. Among them, the lengths of the longitudinally formed strip-shaped sound-transmitting holes and the transversely formed strip-shaped sound-transmitting holes are both greater than the pitch of the LED lamp beads. Since other devices except the LED lamp beads are transferred to the drive control board, the electronic components of the sound-transmitting LED display board are only the LED lamp beads. Therefore, more sound-transmitting holes can be formed on the sound-transmitting LED display board, thereby improving the sound-transmitting rate of the cinema screen. It should be noted that the shape, size, and position of the sound-transmitting holes can be set according to actual needs and are not limited to the limitations in this embodiment.

[0023] In other embodiments, in addition to forming longitudinal strip-shaped sound-transmitting holes and transverse strip-shaped sound-transmitting holes on the sound-transmitting LED display board 100, sound-transmitting holes can also be formed between each adjacent lamp bead. Specifically, sound-transmitting holes are formed on the sound-transmitting LED display board between each adjacent lamp bead. The size and shape of the sound-transmitting holes can be formed according to requirements, for example, circular, square, etc. It is not limited to the limitations in this embodiment.

[0024] In some embodiments, as Figure 2 andFigure 3 As shown, a line driving chip 201, a column driving chip 202, capacitors (not shown in the figure), resistors (not shown in the figure) and solder joints 203 are provided on the driving control board 200. The driving control board 200 is welded to the sound-transmitting LED display board 100 through the solder joints 203. In this embodiment, three driving control boards 200 can be welded to the back of one sound-transmitting LED display board 100. In other embodiments, the number of driving control boards can be increased or decreased according to actual requirements.

[0025] An embodiment of the present invention also provides a sound-transmitting LED cinema screen, which is composed of a plurality of sound-transmitting LED display modules spliced together.
