[0026] To make the present invention easier to understand, the present invention will be more comprehensively described below with reference to the related drawings. The drawings show preferred embodiments of the present invention, but the present invention can be realized in many different ways and is not limited to the embodiments described in this specification. Rather, these embodiments are provided for the purpose of enabling a more complete understanding of the disclosure content of the present invention.

When an element is described as being "connected" to another element, that element may be directly connected to the other element, or an intermediate element may be connected between them.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. Terms used in this description of the present invention are for illustrative purposes only and are not intended to limit the present invention. The terms “and / or” used herein include any and all combinations of the relevant enumerated elements.

[0029] Example 1 As shown by combining Figures 1 and 6, the display device of the present invention is schematically represented and includes a circuit board 10 and a plurality of display components 20.

[0030] The display component 20 includes a plurality of display units 21 arranged in X-sequential order along the reference direction, the plurality of display components 20 are installed in parallel, the display units 21 are provided on the substrate 10, and in this embodiment, the plurality of display units 21 are arranged in an array. The display units 21 are used to emit light so that the display device displays an image.

[0031] The substrate 10 has a front and a back, and a first through-structure is opened in the substrate 10, penetrating from the front to the back of the substrate 10. The first through-structure is located between two adjacent display components 20, and the first through-structure opened in the substrate 10 not only does not affect the light emission effect of the display unit 21, but also allows light and / or sound to pass through the substrate 10. Based on this structure, the display unit 21 can be installed on the front of the substrate 10 and the speaker on the back of the substrate 10. As a result, when sound is output from the speaker, users positioned in the front direction of the substrate 10 will perceive the sound as being output from the display device, achieving a better sound reproduction effect. Furthermore, this display device may be placed in the rear window of a taxi or the glass window of a subway train, thereby enabling image display with minimal impact on light transmission requirements.

[0032] Specifically, the first through-structure includes a plurality of first through-holes 30, the first through-holes 30 may be circular holes, and are arranged so as to surround at least three display units 21. On the other hand, in this embodiment, the plurality of display units 21 are arranged in an array on the substrate 10, so they are arranged so as to surround one first through-hole 30 for every four display units 21. If there are multiple first through-holes 30, the plurality of first through-holes 30 are arranged in an array on the substrate 10. Furthermore, in order to further increase the open area ratio of the substrate 10 (the open area ratio is equal to the total open area of ​​the first through-structure divided by the total area of ​​the front or back of the substrate 10), the first through-structure further includes a plurality of second through-holes 40, the second through-holes 40 are located between two adjacent first through-holes 30, the second through-holes 40 may be circular holes, and the hole diameter of the first through-holes 30 is larger than the hole diameter of the second through-holes 40.

[0033] Furthermore, the orthogonal projection of the display unit 21 onto the substrate 10 forms a rectangle, and the angle between any side of the display unit 21 and the reference direction is 45°. This structure allows for a larger hole diameter for the first through-hole 30, thereby improving the transmittance of the substrate 10. Alternatively, the orthogonal projection of the display unit 21 onto the substrate 10 may form a square, in which case the diagonal of the square of the display unit 21 intersects the axis of the first through-hole 30.

[0034] As shown in Figure 6, the display unit 21 includes a carrier plate 211, a drive chip 213 and multiple types of light-emitting chips 212, each provided on the carrier plate 211. The light-emitting colors of the multiple types of light-emitting chips 212 are different, and preferably there are three types of light-emitting chips 212. The three types of light-emitting chips 212 on each carrier plate 211 are used to emit red light, green light, and blue light, respectively, and the combination of the three types of light can be mixed into many different colors. The carrier plate 211 is connected to the substrate 10, and the drive chip 213 is electrically connected to each of the multiple types of light-emitting chips 212 and is used to control the brightness of the various types of light-emitting chips 212. The display unit 21 is packaged based on the above structure.

[0035] To tile multiple display devices into a larger single display, a second through-structure 70 is provided in the substrate 10, which penetrates to the front and back of the substrate. The second through-structure 70 is located between the edge of the substrate 10 and the display component 20, where the display component 20 is the closest to the edge of the substrate 10. The side of the second through-structure 70 penetrates to the edge of the substrate 10. When the substrates 10 of multiple display devices are tiled together, the openings of the second through-structure 70 of two adjacent substrates 10 are positioned opposite each other. The second through-structures 70 of the two opposing substrates 10 surround each other to form a single first through-structure, thereby maintaining the integrity of the first through-structure in the tiled portion of the two substrates 10 and avoiding any lack of the first through-structure in the tiled portion of the two substrates 10. For example, the second through-hole structure 70 includes a notch located on the side of the substrate 10, and the orthogonal projection of this notch onto the front of the substrate 10 is semicircular. When two substrates 10 are tiled together, the notches of the two substrates 10 are positioned opposite each other, and the two opposing notches surround each other to form a single circular hole, the dimensions of which are the same as the dimensions of the first through-hole 30.

[0036] Example 2 Referring to Figure 2, the differences between this embodiment and Embodiment 1 are as follows: The first through-structure includes a groove 60, which extends along the reference direction, and the presence of the groove 60 results in a higher transmittance of the substrate 10 in this embodiment than that of the substrate 10 in Embodiment 1.

[0037] As shown in Figure 3, in order to further increase the transmittance of the substrate 10, a recessed structure 61 is provided on the inner wall surface of the groove 60, with both ends of the recessed structure 61 penetrating to the front and back surfaces of the substrate 10, respectively, and the recessed structure 61 is located between two adjacent display units 21, and the installation of the recessed structure 61 increases the opening area of ​​the groove 60. Here, as shown in combination with Figures 3 and 4, it is preferable that the contour of the orthogonal projection of the recessed structure 61 on the substrate 10 forms a trapezoid or arc shape.

[0038] Multiple grooves 60 may be provided between two adjacent display components 20, and if multiple grooves 60 are provided, all of the grooves 60 are aligned along the reference direction.

[0039] Example 3 As shown in Figure 5, this embodiment differs from Embodiment 2 in the following ways: Multiple grooves 60 are provided between two adjacent display components 20, and the first through-structure further includes a third through-hole 50, which is located between two adjacent grooves 60, thereby further increasing the transmittance of the substrate 10.

[0040] In summary, the display component 20 on the substrate 10 has a plurality of display units 21 arranged sequentially along the reference direction, and these plurality of display units 21 are used to display images. The first through-structure penetrates to the front and back of the substrate 10, is located between two adjacent display components 20, and can transmit sound and light, improving the sound reproduction effect of the screen and realizing the light-transmitting function of the screen.
