The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Example 1

[0036] 1 and 6 , which schematically illustrate a display device of the present application, the display device includes a substrate 10 and a plurality of display components 20 .

[0037] The display assembly 20 includes a plurality of display units 21 arranged sequentially along a reference direction X. The plurality of display assemblies 20 are arranged in parallel. The display units 21 are disposed on the substrate 10. In this embodiment, the plurality of display units 21 are arranged in a matrix. The display units 21 are configured to emit light so that the display device can display images.

[0038] The substrate 10 has a front and a back surface. The substrate 10 is provided with a first through-structure that penetrates the front and back surfaces thereof. The first through-structure is located between two adjacent display assemblies 20. The first through-structure provided on the substrate 10 not only does not affect the luminous 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 provided on the front surface of the substrate 10, and a speaker can be provided on the back surface of the substrate 10. When the speaker sounds, the user located in the front direction of the substrate 10 can feel the sound emitted by the display device, thereby achieving a better sound reproduction effect. In addition, the display device can also be arranged at the rear window of a taxi or on the glass window of a subway train to display images without affecting the light transmission requirements as much as possible.

[0039] Specifically, the first through-structure includes a plurality of first through-holes 30, which may be circular holes. At least every three display units 21 are arranged around one first through-hole 30. Since the multiple display units 21 in this embodiment are arranged in a matrix on the substrate 10, every four display units 21 are arranged around one first through-hole 30. When there are multiple first through-holes 30, the multiple first through-holes 30 are arranged in a matrix on the substrate 10. To further increase the aperture ratio of the substrate 10 (the aperture ratio is equal to the total aperture area of ​​the first through-structure divided by the total area of ​​the front or back surface of the substrate 10), the first through-structure also includes a plurality of second through-holes 40, which are located between two adjacent first through-holes 30. The second through-holes 40 may be circular holes, and the aperture of the first through-hole 30 is larger than that of the second through-hole 40.

[0040] Furthermore, the projection of the display unit 21 on the substrate 10 is rectangular, and the angle between any side of the display unit 21 and the reference direction is 45°. Based on this structure, the aperture of the first through hole 30 can be further increased to improve the transparency of the substrate 10. The projection of the display unit 21 on the substrate 10 can be square, so that the diagonal of the square of the display unit 21 intersects with the axis of the first through hole 30.

[0041] As shown in Figure 6 , the display unit 21 includes a carrier board 211, a driver chip 213, and multiple light-emitting chips 212, all of which are mounted on the carrier board 211. The multiple light-emitting chips 212 emit different colors, and the number of light-emitting chips 212 is preferably three. The three light-emitting chips 212 on each carrier board 211 are respectively configured to emit red, green, and blue light. The combination of the three lights can be mixed to produce a wide variety of different colors. The carrier board 211 is connected to the substrate 10, and the driver chips 213 are electrically connected to the multiple light-emitting chips 212. The driver chips 213 are used to control the brightness of each light-emitting chip 212. The display unit 21 is packaged based on this structure.

[0042] In order to splice multiple display devices into a larger display screen, the substrate 10 is provided with a second through-structure 70 extending through the front and back thereof. The second through-structure 70 is located between the edge of the substrate 10 and the display assembly 20, wherein the display assembly 20 is the display assembly 20 closest to the edge of the substrate 10, and the side of the second through-structure 70 extends to the edge of the substrate 10. When the substrates 10 of multiple display devices are spliced ​​together, the openings of the second through-structures 70 of the two adjacent substrates 10 are arranged relative to each other, and the second through-structures 70 of the two oppositely arranged substrates 10 form a first through-structure to maintain the integrity of the first through-structure at the splicing point of the two substrates 10, thereby avoiding the loss of the first through-structure at the splicing point of the two substrates 10. For example, the second through-structure 70 includes a notch located on the side of the substrate 10, the projection of the notch on the front of the substrate 10 is semicircular. When the two substrates 10 are spliced ​​together, the notches of the two substrates 10 are arranged relative to each other, and the two oppositely arranged notches form a circular hole, the size of which is consistent with the size of the first through-hole 30.

[0043] Example 2

[0044] As shown in Figure 2, the difference between this embodiment and Example 1 is that the first through structure includes a slot 60, and the slot 60 extends along the reference direction. The setting of the slot 60 allows the permeability of the substrate 10 of this embodiment to be higher than the permeability of the substrate 10 of Example 1.

[0045] As shown in Figure 3 , to further improve the transparency of the substrate 10, a recessed structure 61 is provided on the inner wall of the slot 60. The two ends of the recessed structure 61 extend through the front and back sides of the substrate 10, respectively. The recessed structure 61 is located between two adjacent display units 21. The provision of the recessed structure 61 can increase the opening area of ​​the slot 60. Referring to Figures 3 and 4 , the projection of the recessed structure 61 on the substrate 10 is preferably trapezoidal or arc-shaped.

[0046] A plurality of slots 60 may be provided between two adjacent display assemblies 20 . When there are multiple slots 60 , the multiple slots 60 are arranged along the reference direction.

[0047] Example 3

[0048] As shown in FIG5 , the difference between this embodiment and embodiment 2 is that there are multiple slots 60 between two adjacent display components 20, and the first through-hole structure further includes a third through hole 50, which is located between two adjacent slots 60, thereby further improving the transparency of the substrate 10.

[0049] To sum up, the display component 20 on the substrate 10 has a plurality of display units 21 arranged in sequence along the reference direction for displaying images. The first through-structure penetrates the front and back sides of the substrate 10, and the first through-structure is located between two adjacent display components 20. The first through-structure allows sound and light to pass through, thereby improving the sound reproduction effect of the screen and realizing the light-transmitting function of the screen.
