[0039] Example 2

[0040] Combination Figures 3 to 7 As shown, the difference between this embodiment and Embodiment 1 is that the light-emitting device further includes a power distribution component 30 arranged along the first direction C. The power distribution component 30 is provided with a first interface 31, and the first light-emitting component 10 is provided with a second interface 12. The first interface 31 and the second interface 12 are detachably connected. The power distribution component 30 is used to provide power to multiple first light-emitting components 10. The electrical connection between the power distribution component 30 and the first light-emitting components 10 can be achieved by the connected first interface 31 and second interface 12. Specifically, the power distribution component 30 is provided with multiple first interfaces 31, and each second interface 12 corresponds to one first interface 31, so that each first light-emitting component 10 can be allocated a first interface 31.

[0042] Embodiment 3

[0043] In combination Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , the difference between the present embodiment and embodiment 1 is that the light-emitting device further comprises a first light-emitting module 40 and a second light-emitting module 50 arranged adjacently. The first light-emitting module 40 comprises a plurality of mounting strips 41 extending in the second direction and a plurality of the above-mentioned first light-emitting assemblies 10. The plurality of mounting strips 41 are arranged and spaced apart in the first direction C and decrease in length in turn, and the first light-emitting assemblies 10 are arranged one by one on the mounting strips 41. The plurality of mounting strips 41 arranged and spaced apart can realize the light-transmitting and ventilating function. The second light-emitting module 50 comprises a plurality of second light-emitting assemblies 20 parallel to each other, and the plurality of second light-emitting assemblies 20 are arranged towards the first direction C. The second light-emitting assembly 20 comprises a plurality of second lamp beads 21 arranged towards the second direction D. Similar to the first lamp bead 11, when the plurality of second lamp beads 21 are lit, extinguished or changed in color, the second light-emitting module 50 formed by the plurality of second lamp beads 21 can display a picture. The second lamp bead 21 comprises a plurality of sub-lamp beads, and the colors of the plurality of sub-lamp beads can be different from each other. For example, the number of sub-lamp beads is three, and the colors of the three sub-lamp beads are red, green and blue respectively. Different brightnesses are allocated to each sub-lamp bead, so that the second lamp bead 21 can display different colors. The number of sub-lamp beads can also be four, and the colors of the four sub-lamp beads are red, green, blue and white respectively. The addition of the white sub-lamp bead can significantly improve the overall brightness of the second lamp bead 21.

[0044] The number of the second lamp beads 21 of the plurality of second light-emitting assemblies 20 decreases in turn along the first direction C, which makes the outer contour shape of the second light-emitting module 50 present a triangular or trapezoidal shape. Especially when the outer contour shape of the first light-emitting module 40 presents a trapezoidal shape, the second light-emitting module 50 can be spliced with the first light-emitting module 40, and the two form a light-emitting device with a larger triangular or trapezoidal display area.

[0045] The second light-emitting module 50 mainly solves the problem that the width of the power distribution component 30 in the extension direction limits the length of the first light-emitting assembly 10 in the second direction D, and the first light-emitting assembly 10 needs two points to be connected with the mounting structures 32 on both sides of the power distribution component 30. When the length of the first light-emitting assembly 10 is less than the width of the power distribution component 30, the first light-emitting assembly 10 can only be connected to the mounting structure 32 on one side of the power distribution component 30, and the freedom of the first light-emitting assembly 10 cannot be limited. Therefore, in the case of being equipped with the power distribution component 30, the outer contour shape of the first light-emitting module 40 is trapezoidal, and when the notch 81 of the display screen 80 is triangular, the first light-emitting module 40 and the second light-emitting module 50 need to be spliced with each other to fill the notch 81 of the display screen 80.

[0046] In the embodiment, the second light-emitting module 50 further includes a substrate 52 in the shape of a triangle or a trapezoid, and a plurality of second light-emitting assemblies 20 are arranged in the substrate 52 in the first direction C. The plurality of second light-emitting assemblies 20 arranged in the substrate 52 can realize light transmission and ventilation. The substrate 52 has a straight edge adjacent to the first light-emitting module 40, and the length of the straight edge is less than or equal to the length of the shortest mounting strip 41, so as to ensure that the first light-emitting module 40 and the second light-emitting module 50 after splicing are in the shape of a triangle or a trapezoid. The substrate 52 is provided with a third interface 51, the third interface 51 is electrically connected with the second lamp beads 21 of the second light-emitting assemblies 20, and the third interface 51 is used to be connected with the first interface 31 of the power distribution component 30, so as to realize the power supply of the power distribution component 30 to each second lamp bead 21 of the second light-emitting assemblies 20.

[0047] In addition, the third interface 51 further includes a plurality of pins, and the pins at least include a positive pin, a negative pin, and a data signal pin. The positive pin and the negative pin can be used to provide power for the second lamp beads 21 of the second light-emitting assemblies 20, and the number of the data signal pins is equal to the number of the second light-emitting assemblies 20, so that each data signal pin can control the second lamp beads 21 on one second light-emitting assembly 20. In other optional embodiments, the pins further include at least one of a clock signal pin, a latch signal pin, and an enable signal pin.

[0048] Embodiment 4

[0049] As Figure 8 , the embodiment provides a display device including a display screen 80 and the above-mentioned light-emitting device. One corner of the display screen 80 has a triangular notch 81, and the light-emitting device with a triangular outer contour is arranged in the notch 81.

[0050] In summary, the plurality of first light emitting components 10 are arranged in the first direction C and arranged in parallel with each other, the first light emitting component 10 has a plurality of first lamp beads 11 arranged in the second direction D, the first direction C and the second direction D are perpendicular to each other, the plurality of first lamp beads 11 are turned on to combine a display picture, in the first direction C, the number of first lamp beads 11 of the Nth first light emitting component 10 is less than the number of first lamp beads 11 of the (N-1)th first light emitting component 10, wherein N≥2 and N is an integer, which makes the light emitting device trapezoidal or triangular to fill the gap 81 of the existing display screen 80.
