Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a transparent LED display screen. Background Technology

[0002] Existing transparent LED displays mainly achieve the transparency effect by creating multiple through holes on the PCB board, while LED beads are arranged in a dot matrix pattern in the gaps between the through holes to form the display surface. Although some of the sound from the speakers behind the transparent screen can pass through the through holes and be heard by people on the display side of the transparent screen, some sound is blocked in the areas of the PCB board without through holes, making the sound relatively low for people on the display side of the transparent screen, thus affecting the usability of the transparent screen.

[0007] Multiple sound-gathering sections are provided on the mounting section on the second surface, and a converging surface facing the center of the through hole is provided to converge the sound waves at the location of the mounting section into the through hole.

[0008] Furthermore, the sound-gathering part includes a groove disposed around the through hole, the groove wall gradually expanding from the direction close to the through hole to the direction away from the through hole.

[0009] Furthermore, the groove is composed of four first protrusions surrounding the through hole, and adjacent first protrusions are connected by an inwardly concave arc-shaped structure.

[0026] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of a transparent LED display screen provided by an embodiment of the present utility model. The transparent LED display screen includes a PCB board 10, multiple LED beads 20, and multiple sound-focusing parts 30.

[0027] Please combine Figures 2-4 The PCB board 10 has a first surface 110 and a second surface 120 facing each other. The PCB board 10 includes a transparent portion 130 with a plurality of through holes 101 and a mounting portion 140 without through holes 101. A plurality of LED beads 20 are mounted on the mounting portion 140 of the first surface 110. A plurality of sound-focusing portions 30 are provided on the mounting portion 140 of the second surface 120 and have a converging surface 301 facing the center of the through holes 101 for converging sound waves at the position of the mounting portion 140 into the through holes 101.

[0028] Here, the first surface 110 and the second surface 120 are the front and back surfaces of the PCB board 10. The plurality of LED beads 20 are arranged in an array on the first surface 110 of the PCB board 10. Specifically, the PCB board 10 has a plurality of through holes 101, which divides the PCB board 10 into a transparent portion 130 with the through holes 101 and a mounting portion 140 without the through holes 101. The plurality of LED beads 20 are mounted on the mounting portion 140 of the first surface 110, so that a pattern is formed on the first surface 110 of the PCB board 10. The multiple sound-gathering parts 30 are structures for converging sound on the second surface 120 of the PCB board 10 away from the display surface. Specifically, they are disposed on the mounting part 140 of the second surface 120. Each of the multiple sound-gathering parts 30 has a converging surface 301 facing the center of the through hole 101. The converging surface 301 can converge the sound waves from the mounting part 140 on the back of the display screen into the through hole 101, and then transmit them through the through hole 101 to the front of the display screen, so that people on the display side can hear a louder sound, thereby improving the performance of the transparent LED display screen.

[0029] Furthermore, in other preferred embodiments of the present invention, the sound-gathering part 30 includes a groove 310 disposed around the through hole 101, the groove wall of the groove 310 gradually expanding from the direction close to the through hole 101 to the direction away from the through hole 101.

[0030] Specifically, the plurality of sound-gathering parts 30 are multiple groove structures disposed on the back of the PCB board 10. The grooves 310 surround the through hole 101, and the groove walls of the grooves 310 gradually expand from the direction close to the through hole 101 to the direction away from the through hole 101, thereby making the grooves 310 form a horn-like structure, so as to achieve a good sound wave gathering effect, and further enable people on the display side to hear a louder sound, thereby improving the use effect of the transparent LED display screen.

[0031] Furthermore, in other preferred embodiments of the present invention, the groove 310 is composed of four first protrusions 3101 surrounding the through hole 101, and two adjacent first protrusions 3101 are connected by an inwardly concave arc-shaped structure.

[0032] Specifically, four first protrusions 3101 are provided outside the through hole 101. The four first protrusions 3101 are connected in sequence to form a groove 310 similar to a groove structure. Adjacent first protrusions 3101 are connected by an inwardly concave arc structure. This structure allows sound waves from the mounting part 140 on the back of the display screen to smoothly enter the through hole 101, further improving its sound wave focusing effect.

[0033] In other preferred embodiments of the present invention, the sound-gathering part 30 includes a fence 320 disposed around the through hole 101, and the inner wall of the fence 320 gradually expands from the direction close to the through hole 101 to the direction away from the through hole 101.

[0034] Specifically, the fence 320 is arranged around the perimeter of the through hole 101, but the fence 320 is not completely perpendicular to the second surface 120 of the PCB board 10, but has a certain tilt angle, so that the inner wall of the fence 320 gradually expands from the direction close to the through hole 101 to the direction away from the through hole 101, so that the fence 320 forms a horn-like structure, so as to achieve a good sound wave converging effect, and further enable people on the display side to hear a louder sound, thereby improving the use effect of the transparent LED display screen.

[0035] Furthermore, in other preferred embodiments of the present invention, the fence 320 includes a second protrusion 3201 surrounding the through hole 101, the thickness of the second protrusion 3201 gradually decreasing from the direction close to the through hole 101 to the direction away from the through hole 101.

[0036] Specifically, the second protrusion 3201 surrounds the through hole 101 of the second surface 120 to form the fence 320, and the thickness of the second protrusion 3201 gradually decreases from the direction close to the through hole 101 to the direction away from the through hole 101. This structure can ensure that the fence 320 forms a sound wave converging structure similar to a horn, so that the sound waves at the mounting part 140 on the back of the display screen can smoothly enter the through hole 101, further improving its sound wave converging effect.

[0037] Furthermore, in other preferred embodiments of this utility model, each LED bead 20 is provided with at least three through holes 101 on its periphery.

[0038] Specifically, the LED beads 20 are disposed in the mounting portions 140 within at least three of the through holes 101, so that the transparent portion 130 forms a honeycomb-like structure. This structure can ensure that the transparent portion 130 of the display screen has good transparency, thereby improving the transparency effect of the transparent LED display screen.

[0039] Furthermore, in other preferred embodiments of this invention, at least three of the through holes 101 are equally spaced around the LED beads 20. This structure ensures that the LED beads 20 and the centers of the multiple through holes 101 around them have the same distance, making the layout of the LED beads 20 and the through holes 101 more uniform, thereby improving the display effect of the transparent LED display screen.

[0040] In other preferred embodiments of this invention, each LED bead 20 is provided with four through holes 101 at equal intervals around its periphery. This structure can improve the transparency of the transparent portion 130 of the display screen, further enhancing the transparency effect of the transparent LED display screen.

[0041] Furthermore, in other preferred embodiments of this utility model, the sound-collecting part 30 is bonded to the PCB board 10.

[0042] Specifically, the plurality of sound-gathering parts 30 are interconnected to form an integrated plate-like structure. The plate-like structure is disposed on the second surface 120 of the PCB board 10 and is connected to the PCB board 10 by adhesive.

[0043] Furthermore, in other preferred embodiments of this utility model, the sound-gathering part 30 and the PCB board 10 are an integral structure.

[0044] Specifically, the sound-gathering part 30 and the PCB board 10 are an integral structure. The multiple sound-gathering parts 30 can be regarded as the back of the PCB board 10, that is, the multiple sound-gathering parts 30 are multiple protruding structures on the second surface 120 of the PCB board 10. The protruding structures can concentrate the sound waves at the mounting part 140 position on the back of the display screen into the through hole 101.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
