[0002] With the continuous development of technology, LED displays, with their seamless splicing and excellent color reproduction, are now widely used not only in billboards, conference rooms, and high-speed rail stations, but also in stages, exhibition halls, and film studios. As the application fields of LED displays become increasingly broad, LED display manufacturers are also beginning to enter cinemas and theaters.
[0003] The application of LED displays is becoming increasingly widespread, and different applications often have different requirements. For cinemas and theaters, in addition to meeting cinema display standards, cinemas also have high requirements for sound quality to ensure an immersive audio-visual experience for the audience. LED cinema screens differ from traditional projectors, whose screens have high sound transmittance, easily meeting cinema sound standards. LED cinema screens are typically assembled from printed circuit boards. In practical cases, when using LED displays in cinemas, the low sound transmittance of the screen often results in unsatisfactory sound effects. Summary of the Invention

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0020] Furthermore, the technical features involved in the different embodiments of the present invention 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 invention provides a sound-transparent LED display module 1, including a base shell (not shown), a sound-transparent LED display panel 100, and a drive control board 200. The sound-transparent LED display panel 100 has sound-transparent holes 101. The drive control board 200 is soldered to the back of the sound-transparent LED display panel 100. The sound-transparent LED display panel 100 and the drive control board 200 are mounted on the base shell. By separating the display circuit and the drive circuit, and by creating sound-transparent holes on the sound-transparent LED display panel, the sound transmission rate can be improved, ensuring sound quality.
[0022] In some embodiments, as shown in Figure 1, the acoustically transparent LED display panel 100 is provided with LED beads 102, which are evenly spaced on the acoustically transparent LED display panel 100. The acoustically transparent LED display panel 100 has longitudinally formed strip-shaped sound-transmitting holes 101. In other embodiments, the acoustically transparent LED display panel 100 has transversely formed strip-shaped sound-transmitting holes. The lengths of both the longitudinally and transversely formed strip-shaped sound-transmitting holes are greater than the spacing between the LED beads. Since all components except the LED beads are transferred to the drive control board, the only electronic component of the acoustically transparent LED display panel is the LED beads. Therefore, the acoustically transparent LED display panel can have more sound-transmitting holes, thereby improving the sound transmission 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 of this embodiment.
[0023] In other embodiments, in addition to the longitudinal and transverse strip-shaped sound-permeable holes on the sound-permeable LED display panel 100, sound-permeable holes can also be formed between each adjacent LED bead. Specifically, sound-permeable holes are formed on the sound-permeable LED display panel between each adjacent LED bead. The size and shape of the sound-permeable holes can be formed according to requirements, for example, circular, square, etc. There is no need to be limited by the limitations of this embodiment.
[0024] In some embodiments, as shown in Figures 2 and 3, the drive control board 200 is provided with a row drive chip 201, a column drive chip 202, a capacitor (not shown), a resistor (not shown), and solder pads 203. The drive control board 200 is soldered to the acoustically transparent LED display panel 100 via the solder pads 203. In this embodiment, three drive control boards 200 can be soldered to the back of one acoustically transparent LED display panel 100. In other embodiments, the number of drive control boards can be increased or decreased according to actual needs.
[0025] This invention also provides an acoustically transparent LED cinema screen, which is composed of multiple acoustically transparent LED display modules spliced together.
[0026] It should be noted that while the preferred embodiments of the present invention are provided in the specification and accompanying drawings, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of the present invention; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of the present invention. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of the present invention specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
