Figures 1-4 As shown, this application embodiment provides a light-emitting panel 10, which includes a first light-emitting area 101 and a second light-emitting area 102. The first light-emitting area 101 is located on the side of the second light-emitting area 102 near the edge of the light-emitting panel 10. The first light-emitting area 101 is provided with a plurality of first light-emitting elements 201. The light-emitting panel 10 also includes a light-emitting adjustment structure 300, which is located on the light-emitting side of the first light-emitting element 201, and the surface of the light-emitting adjustment structure 300 facing the first light-emitting element 201 is non-planar.

[0038] Among them, reference Figure 1 As shown, the light-emitting panel 10 provided in this embodiment includes a plurality of light-emitting elements 200. By driving the plurality of light-emitting elements 200 to emit light, the light-emitting function of the light-emitting panel 10 can be realized. Further, refer to... Figure 1 As shown, the light-emitting panel 10 includes a first light-emitting area 101 and a second light-emitting area 102. The first light-emitting area 101 and the second light-emitting area 102 divide the light-emitting panel 10 into regions. The first light-emitting area 101 is closer to the edge of the light-emitting panel 10 than the second light-emitting area 102. Therefore, the first light-emitting area 101 can be understood as the light-emitting area near the edge of the light-emitting panel 10, and the second light-emitting area 102 can be understood as the light-emitting area near the center of the light-emitting panel 10. Specifically, refer to... Figure 1 As shown, the light-emitting element 200 disposed in the first light-emitting area 101 is the first light-emitting element 201. Optionally, the light-emitting element 200 can be a light-emitting element that emits white light, a light-emitting element that emits blue light, or a light-emitting element that emits purple light. The light emitted by the light-emitting element 200 can be selected according to different light-emitting panels 10, and this application does not make specific limitations in this regard.

[0039] Specifically, the first light emitting element 201 disposed at the first light emitting area 101 is closer to the edge of the light emitting panel 10 than the light emitting element 200 disposed at the second light emitting area 102, so there is a difference in light emitting brightness between the first light emitting area 101 and the second light emitting area 102. Specifically, the difference in brightness between the first light emitting area 101 and the second light emitting area 102 can be understood as follows: on the one hand, since the first light emitting element 201 is closer to the edge of the light emitting panel 10, the number of light emitting elements 200 disposed on the side of the first light emitting element 201 close to the edge of the light emitting panel 10 is less or no additional light emitting element 200 is disposed. Therefore, the number of light emitting elements 200 around the first light emitting element 201 that can compensate for brightness is relatively small, and thus the light emitting brightness of the first light emitting area 101 is weaker than that of the second light emitting area 102. On the other hand, the first light emitting element 201 is disposed closer to the edge of the light emitting panel 10, so part of the light emitted by the first light emitting element 201 will be emitted at the gap of the first light emitting element 201 close to the edge of the light emitting panel 10. The gap at the edge can be understood as the junction of the light emitting area and the non-light emitting area of the light emitting panel 10, and the gap at the edge of the light emitting panel 10 does not belong to the effective light emitting area of the light emitting panel 10, so it will reduce the overall light emitting efficiency of the first light emitting element 201, also causing the light emitting brightness of the first light emitting area 101 to be weaker than that of the second light emitting area 102, and also causing the light emitting panel 10 to leak light at the edge.

[0040] Further, in order to ensure that the light emitting brightness of the first light emitting area 101 and the light emitting brightness of the second light emitting area 102 are similar, and to ensure the light emitting uniformity of the light emitting panel 10 and avoid the light emitting panel 10 from leaking light at the edge, the light emitting panel 10 provided in the embodiment of the present application further comprises a light emitting adjusting structure 300. Referring to Figures 2-4 As shown, the light emitting adjusting structure 300 is disposed at least at the first light emitting area 101. By adjusting the emitted light of the first light emitting element 201 through the light emitting adjusting structure 300, the light emitting brightness of the first light emitting area 101 can be improved, the light emitting brightness of the first light emitting area 101 can be ensured to be similar to the light emitting brightness of the second light emitting area 102, and thus the light emitting uniformity of the light emitting panel 10 as a whole can be ensured. At the same time, the light emitting adjusting structure 300 can also avoid or reduce the transmission of the emitted light of the first light emitting element 201 to the edge of the light emitting panel 10, weaken the situation that the light emitting panel 10 leaks light at the edge area, and ensure the light emitting effect of the light emitting panel 10 as a whole

[0041] Specifically, referring to Figures 2-4As shown, the surface of the light-emitting adjustment structure 300 facing the first light-emitting element 201 is non-planar. When the light emitted from the first light-emitting element 201 reaches the non-planar surface of the light-emitting adjustment structure 300, the light transmission path can be adjusted, thereby adjusting the light emitted by the first light-emitting element 201. This ensures that the light emitted from the first light-emitting element 201 is emitted as close as possible to the light-emitting direction of the light-emitting element 201, thus increasing the luminous intensity of the first light-emitting area 101. This ensures that the luminous brightness of the first light-emitting area 101 is similar to that of the second light-emitting area 102, guaranteeing the overall luminous effect of the light-emitting panel 10. It also prevents light from leaking out from the gaps at the edges of the light-emitting panel 10. For example, refer to... Figure 2 As shown, Figure 2 The areas indicated by arrows a1 and a2 can be understood as the non-planar areas of the light emission adjustment structure 300; (Reference) Figure 3 As shown, Figure 3 The area indicated by the middle arrow a3 can be understood as the non-planar part of the light emission adjustment structure 300; Reference Figure 4 As shown, Figure 3 The areas indicated by arrows a4, a5, and a6 can be understood as the non-planar parts of the light emission adjustment structure 300. It should be noted that the light emission adjustment structure 300 can be configured in various ways. Figures 2-4 Used as an example. Also, Figures 2-4 In order to distinguish the light-emitting adjustment structure 300 from other structures, the light-emitting adjustment structure 300 is filled with a pattern in the accompanying drawings provided in this application embodiment.

[0042] In summary, the light-emitting panel 10 provided in this application embodiment has a light-emitting adjustment structure 300 provided in the first light-emitting area 101, and the surface of the light-emitting adjustment structure 300 facing the first light-emitting element 201 includes a non-planar area. The non-planarity allows for adjustment of the light emitted from the first light-emitting element 201, increasing the brightness of the first light-emitting area 101. It also reduces or avoids light leakage at the gaps at the edges of the light-emitting panel 10, ensuring balanced brightness between the first light-emitting area 101 and the second light-emitting area 102, reducing color difference between different areas of the light-emitting panel 10, and ensuring balanced brightness across different areas of the light-emitting panel 10.

[0043] Optional, see reference Figures 2-4As shown, the light-emitting panel 10 may further include a frame structure 400, which supports and protects the overall structure. Specifically, the frame structure 400 includes a support frame 410 and a frame frame 420. The support frame 410 ensures the stability of the overall structure, and the frame frame 420 further protects the overall structure. The support frame 410 includes a first support unit 411 and a second support unit 412 connected to each other, and the frame frame 420 includes a first frame unit 421 and a second frame unit 422 connected to each other. The first support unit 411 is arranged perpendicular to the light-emitting element 200, and the second support unit 412 is arranged along the light-emitting element 200. The first frame unit 421 is arranged perpendicular to the light-emitting element 200 and is located in the central region of the first support unit 411 away from the light-emitting panel 10; the second frame unit 422 is arranged along the light-emitting element 200 and is located on the side of the second support unit 412 away from the light-emitting element 200.

[0044] Optionally, the light-emitting panel 10 also includes an optical film 500 disposed on the light-emitting side of the light-emitting element 200. The optical film 500 may include a diffusion layer, a brightness enhancement film, or a color conversion layer, etc. In this embodiment, the film layers included in the optical film 500 are not specifically limited. The frame frame 420 can also serve as a limiting structure for the optical film 500 to prevent the optical film 500 from warping off during mechanical testing and to ensure the stability of the overall structure.

[0045] Optionally, the light-emitting elements in the light-emitting panel may include different light-emitting surface types. For example, the light-emitting element may be a Lambertian light-emitting surface type, or the light-emitting element may be a bat wing light-emitting surface type. This application does not specifically limit the specific light-emitting model of the light-emitting element.

[0046] In summary, this application provides a light-emitting panel with a light-emitting adjustment structure. This structure can adjust the light emission of a first light-emitting element located in a first light-emitting area, thereby improving the light emission effect of the first light-emitting area. Furthermore, the surface of the light-emitting adjustment structure near the first light-emitting element is non-planar. By using this non-planar structure to adjust the light emission of the first light-emitting element, the brightness of the first light-emitting area can be adjusted. This also prevents light from escaping from gaps at the edges of the light-emitting panel, ensuring the overall uniformity of light emission and the overall light emission effect of the panel.

[0047] Based on the above embodiments, Figure 5 This is a schematic diagram illustrating the fabrication process of a light-emitting panel according to an embodiment of this application. Figure 6 This is an enlarged schematic diagram of the first light emission adjustment structure provided in the embodiments of this application. (Continue referring to...)Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the light emission adjustment structure 300 includes a first light emission adjustment structure 310, which includes a plurality of first clearance slots 311, and the first clearance slots 311 cover at least one first light-emitting element 201.

[0048] For details, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the light emission adjustment structure 300 includes a first light emission adjustment structure 310, which includes a plurality of first clearance slots 311, and the first clearance slots 311 cover at least one first light-emitting element 201. Figure 2 , Figure 4 and Figure 6 The example provided illustrates a first light-emitting element 201 covered by a first recess 311. The number of first light-emitting elements 201 covered by the first recess 311 can be adjusted according to actual needs. For example, the size of the first recess 311 can be increased to accommodate more first light-emitting elements 201. This application does not impose a specific limitation on this.

[0049] Further reference Figure 6 As shown, the first recess 311 covers the first light-emitting element 201. The surface of the first recess 311 near the first light-emitting element 201 is used to adjust the light emitted from the first light-emitting element 201. Therefore, the surface of the first recess 311 near the first light-emitting element 201 can be non-planar, thereby ensuring the improvement of the light intensity of the first light-emitting area 101.

[0050] Further reference Figure 5 As shown, the fabrication process of the light-emitting panel 10 can be as follows: First, refer to... Figure 5 As shown in step a, a first light-emitting element 201 is fabricated in the first light-emitting region 101. (Refer to...) Figure 5 As shown in step b, a light emission adjustment structure 300 is provided. One surface of the light emission adjustment structure 300 is non-planar. Finally, refer to... Figure 5As shown in step c, the light-emitting adjustment structure 300 is placed on the light-emitting side of the first light-emitting element 201, with the non-planar surface of the light-emitting adjustment structure 300 facing the first light-emitting element 201. This can be understood as the light-emitting adjustment structure 300 being a structure first prepared using other processes, such as injection molding or hot pressing. After preparation, the first light-emitting adjustment structure 310 is placed on one side of the first light-emitting element 201. Therefore, when the surface of the light-emitting adjustment structure 300 is designed to be non-planar, the related preparation process will not damage the light-emitting element 200, and thus will not affect the light-emitting effect of the light-emitting panel 10. Therefore, the first clearance groove 311 in the first light-emitting adjustment structure 310 will not damage the first light-emitting element 201, and by setting the first clearance groove 311, the alignment accuracy of the first light-emitting adjustment structure 310 when moving to the first light-emitting element 201 can be improved, reducing the transfer difficulty of the first light-emitting adjustment structure 310 and ensuring that the preparation of the light-emitting panel 10 is more reliable.

[0051] For details, please refer to Figure 6 As shown, the first clearance groove 311 includes an inner surface 311a, and at least a portion of the inner surface 311a is provided with a Fresnel lens.

[0052] refer to Figure 6 As shown, the first recess 311 covers the first light-emitting element 201, and the light emitted from the first light-emitting element 201 is transmitted to the inner surface 311a of the first recess 311. Therefore, the inner surface 311a of the first recess 311 is used to adjust the light emitted from the first light-emitting element 201. Specifically, in order to ensure the adjustment of the light emitted from the first light-emitting element 201, the inner surface 311a of the first recess 311 is designed as a non-planar surface. For example, refer to... Figure 6 As shown, at least a portion of the inner surface 311a is provided with a Fresnel lens.

[0053] Fresnel lenses, also known as threaded lenses, are optical elements that divide the curved surface of a traditional lens into a series of concentric rings (called Fresnel rings or Fresnel bands) and flatten them onto the same plane. They adjust light through the principle of refraction and have the advantages of being thinner, lighter, and less expensive than traditional lenses. Designing the non-planar inner surface 311a as a Fresnel lens can utilize the converging effect of the Fresnel lens to concentrate the light emitted from the first light-emitting element 201, thereby increasing the brightness of the first light-emitting area 101 and preventing the light emitted from the first light-emitting element 201 from scattering in all directions, thus preventing light leakage at the edges of the light-emitting panel 10.

[0054] Continue to refer to Figure 6As shown, the light-emitting panel 10 also includes a driving substrate 600. A first light-emitting element 201 is disposed on one side of the driving substrate 600 and electrically connected to the driving substrate 600. The first light-emitting element 201 includes an upper light-emitting surface 201a, which is the light-emitting surface of the first light-emitting element 201 away from the driving substrate 600. The inner surface 311a includes an upper inner surface 311a1 located on the side of the upper light-emitting surface 201a away from the driving substrate 600. A first Fresnel lens is disposed on the upper inner surface 311a1.

[0055] For details, please refer to Figures 2-4 , Figure 6 As shown, the light-emitting panel 10 includes a driving substrate 600, which serves as a carrier substrate for the light-emitting element 200. Furthermore, a driving circuit electrically connected to the light-emitting element 200 is disposed above or inside the driving substrate 600 to provide a light-emitting driving signal to the light-emitting element 200, thereby driving the light-emitting element 200 to emit light.

[0056] Further reference Figure 6 As shown, the first light-emitting element 201 includes an upper light-emitting surface 201a, which is the light-emitting surface of the first light-emitting element 201 away from the driving substrate 600. Specifically, the upper light-emitting surface 201a can be understood as the light-emitting surface corresponding to the light-emitting side of the first light-emitting element 201, and therefore can also be understood as the main light-emitting surface of the first light-emitting element 201a. The first light-emitting adjustment structure 310 can adjust the light emitted from the upper light-emitting surface 201a, improving the light-emitting efficiency of the first light-emitting element 201, increasing the brightness of the first light-emitting area 101, and preventing the light emitted from the first light-emitting element 201 from leaking out through the gaps at the edge of the light-emitting panel 10.

[0057] Specifically, in the first recessed groove 311, the inner surface 311a includes an upper inner surface 311a1 located on the side of the upper light-emitting surface 201a away from the driving substrate 600, and a first Fresnel lens is provided on the upper inner surface 311a1. Combined with the light-adjusting effect of the Fresnel lens, the upper inner surface 311a1 can effectively adjust the light emitted from the upper light-emitting surface 201a. Specifically, the upper inner surface 311a1 can converge the emitted light from the first light-emitting element 201, increase the brightness of the first light-emitting area 101, reduce the brightness difference between the first light-emitting area 101 and the second light-emitting area 102, ensure the light emission uniformity of the light-emitting panel 10, and effectively prevent the light emitted from the first light-emitting element 201 from escaping through the gaps at the edges of the light-emitting panel 10, thus preventing light leakage at these gaps.

[0058] Continue to refer to Figure 6As shown, the first light-emitting element 201 further includes a side light-emitting surface 201b, which is connected to the upper light-emitting surface 201a; the inner surface 311a further includes a side inner surface 311a2, which is connected to the upper inner surface 311a1 and located on one side of the side light-emitting surface 201b; a second Fresnel lens is provided on the side inner surface 311a2.

[0059] Further reference Figure 6 As shown, the first light-emitting element 201 also includes a side-emitting surface 201b, and both the side-emitting surface 201b and the main light-emitting surface 201a are light-emitting surfaces of the first light-emitting element 201. Furthermore, in order to better adjust the light emitted from the first light-emitting element 201, the first light-emitting adjustment structure 310 can adjust both the light emitted from the upper light-emitting surface 201a and the light emitted from the side-emitting surface 201b, thereby further improving the light-emitting efficiency of the first light-emitting element 201, better ensuring the brightness of the first light-emitting area 101, and preventing the light emitted from the first light-emitting element 201 from leaking out from the edge of the light-emitting panel 10.

[0060] For details, please refer to Figure 6 As shown, the inner surface 311a of the first recessed groove 311 also includes a side inner surface 311a2. The side inner surface 311a2 is connected to the upper inner surface 311a1 and located on one side of the side emitting surface 201b. A second Fresnel lens is provided on the side inner surface 311a2. Combined with the light adjustment effect of the Fresnel lens, the second Fresnel lens in the side inner surface 311a2 can effectively adjust the light emitted from the side emitting surface 201b. Specifically, both the upper inner surface 311a1 and the side inner surface 311a2 can converge the emitted light from the first emitting element 201, further improving the luminous brightness of the first emitting area 101, reducing the luminous brightness difference between the first emitting area 101 and the second emitting area 102, and ensuring the luminous balance of the emitting panel 10. At the same time, it effectively prevents the light emitted from the first emitting element 201 from escaping through the gaps at the edges of the emitting panel 10, avoiding light leakage at the gaps at the edges of the emitting panel 10.

[0061] Figure 7 This is an enlarged schematic diagram of the second type of first light emission adjustment structure provided in the embodiments of this application, with reference to... Figure 6 and Figure 7As shown, the side-emitting surface 201b includes a first side-emitting surface 201b1 and a second side-emitting surface 201b2. The first side-emitting surface 201b1 is located on the side of the second side-emitting surface 201b2 that is close to the edge of the light-emitting panel 10. The side inner surface 311a2 includes a first side inner surface 311a21 and a second side inner surface 311a22. The first side inner surface 311a21 is located on the side of the first side-emitting surface 201b1 that is close to the edge of the light-emitting panel 10, and the second side inner surface 311a22 is located on the side of the second side-emitting surface 201b2 that is away from the edge of the light-emitting panel 10. Both the first side inner surface 311a21 and the second side inner surface 311a22 are provided with a second Fresnel lens, and the distribution density of the Fresnel rings in the second Fresnel lens of the first side inner surface 311a21 is greater than or equal to the distribution density of the Fresnel rings in the second Fresnel lens of the second side inner surface 311a22.

[0062] For details, please refer to Figure 6 and Figure 7 As shown, in the first light-emitting element 201, the side-emitting surface 201b includes a first side-emitting surface 201b1 and a second side-emitting surface 201b2, wherein the first side-emitting surface 201b1 is located on the side of the second side-emitting surface 201b2 closer to the edge of the light-emitting panel 10. In order to reduce or prevent the light emitted from the first light-emitting element 201 from being transmitted to the gap at the edge of the light-emitting panel 10, and to avoid light leakage at the gap at the edge of the light-emitting panel 10, the adjustment intensity of the light emitted from the first side-emitting surface 201b1 can be set to be greater than or equal to the adjustment intensity of the light emitted from the second side-emitting surface 201b2.

[0063] Among them, on the inner surface 311a of the first recess groove 311, the side inner surface 311a2 includes a first side inner surface 311a21 and a second side inner surface 311a22. The first side inner surface 311a21 is located on the side of the first side light-emitting surface 201b1 near the edge of the light-emitting panel 10. (Refer to...) Figure 6 and Figure 7 As shown, the first inner surface 311a21 can adjust the light emitted from the first emitting surface 201b1, and the second inner surface 311a22 can adjust the light emitted from the second emitting surface 201b2. Specifically, both the first inner surface 311a21 and the second inner surface 311a22 are provided with second Fresnel lenses. In order to ensure that the adjustment intensity of the light emitted from the first emitting surface 201b1 is greater than or equal to the adjustment intensity of the light emitted from the second emitting surface 201b2, the distribution density of the Fresnel rings of the second Fresnel lenses on the first inner surface 311a21 and the second inner surface 311a22 can be adjusted.

[0064] For details, please refer to Figure 7As shown, the distribution density of Fresnel rings in the second Fresnel lens on the first inner surface 311a21 is equal to the distribution density of Fresnel rings in the second Fresnel lens on the second inner surface 311a22. This ensures that the emitted light from both the first emitting surface 201b1 and the second emitting surface 201b2 can be effectively adjusted, while also reducing the design difficulty and manufacturing difficulty of the first light-emitting adjustment structure 310.

[0065] For details, please refer to Figure 6 As shown, the distribution density of Fresnel rings in the second Fresnel lens on the first inner surface 311a21 is greater than that in the second Fresnel lens on the second inner surface 311a22. This allows the adjustment intensity of the light emitted from the first emitting surface 201b1 to be greater than that of the light emitted from the second emitting surface 201b2, ensuring a better light adjustment effect on the first emitting element 201 and a better focusing effect on the emitted light from the first emitting element 201.

[0066] It should be noted that, Figure 6 and Figure 7 In the diagram, the distribution density of Fresnel rings in the second Fresnel lens can be represented by the number of Fresnel rings per unit area. In the figure, area b1 represents one Fresnel ring. For example... Figure 6 In the second Fresnel lens on the first inner surface 311a21, the number of Fresnel rings per unit area is greater than the number of Fresnel rings per unit area on the second inner surface 311a22. For example... Figure 7 In the second Fresnel lens on the first inner surface 311a21, the number of Fresnel rings per unit area is equal to the number of Fresnel rings per unit area on the second inner surface 311a22. The distribution density of the Fresnel rings can also be reflected by the size of the Fresnel rings, etc., but this application does not impose specific limitations on this.

[0067] Figure 8 This is an enlarged schematic diagram of the third type of first light emission adjustment structure provided in the embodiments of this application, with reference to... Figure 8 As shown, the distribution density of Fresnel rings in the first Fresnel lens is greater than or equal to the distribution density of Fresnel rings in the second Fresnel lens.

[0068] Specifically, in the first light-emitting element 201, compared to the side light-emitting surface 201a, the upper light-emitting surface 201a can be understood as the main light-emitting surface of the first light-emitting element 201, and the side light-emitting surface 201b can be understood as the secondary light-emitting surface of the first light-emitting element 201. Therefore, in order to achieve efficient adjustment of the light emission of the first light-emitting element 201 and better focus the light emitted from the first light-emitting element 201, the first light emission adjustment structure 310 can preferentially adjust the light emission of the upper light-emitting surface 201a or adjust the light emission of the light-emitting surface 201a to a greater extent. Therefore, the distribution density of the Fresnel rings in the first Fresnel lens can be adjusted to be greater than or equal to the distribution density of the Fresnel rings in the second Fresnel lens. For example, refer to Figure 8 As shown, taking the example that the number of Fresnel rings per unit area in the first Fresnel lens is greater than the number of Fresnel rings per unit area in the second Fresnel lens, it can be seen that the distribution density of Fresnel rings in the first Fresnel lens is greater than that in the second Fresnel lens, thus better ensuring the focusing adjustment effect on the light emitted from the first light-emitting element 201. Optionally, in order to ensure the structural regularity of the first light-emitting adjustment structure 310, the number of Fresnel rings per unit area in the first Fresnel lens can be adjusted to be equal to the number of Fresnel rings per unit area in the second Fresnel lens. This ensures the focusing adjustment effect on the light emitted from the first light-emitting element 201 while reducing the manufacturing difficulty of the first light-emitting adjustment structure 310.

[0069] Continue to refer to Figure 8 As shown, the minimum distance between the upper luminous surface 201a and the upper inner surface 311a1 is less than or equal to the minimum distance between the side luminous surface 201b and the side inner surface 311a22.

[0070] The smaller the relative minimum distance between the first recessed groove 311 and the first light-emitting element 201, the more obvious the focusing adjustment effect of the Fresnel lens in the first recessed groove 311 on the light emitted from the first light-emitting element 201. Specifically, in the first light-emitting element 201, compared with the side light-emitting surface 201b, the upper light-emitting surface 201a can be understood as the main light-emitting surface of the first light-emitting element 201, and the side light-emitting surface 201b can be understood as the secondary light-emitting surface of the first light-emitting element 201. Therefore, in order to achieve the light emission adjustment effect of the first light-emitting element 201 and better focus the light emitted from the first light-emitting element 201, the first light emission adjustment structure 310 can adjust the minimum distance between the upper light-emitting surface 201a and the upper inner surface 311a1 to be less than or equal to the minimum distance between the side light-emitting surface 201b and the side inner surface 311a22. For example, refer to Figure 8As shown, the minimum distance between the light-emitting surface 201a and the upper inner surface 311a1 is L1, and the minimum distance between the side light-emitting surface 201b and the side inner surface 311a22 is L2. L1 can be adjusted to be greater than or equal to L2. This also demonstrates the versatility of the arrangement of the first light-emitting adjustment structure 310.

[0071] Continue to refer to Figures 6-8 As shown, the first Fresnel lens and the second Fresnel lens are set independently.

[0072] In the first light-emitting element 201, the main light-emitting surface 201a and the side light-emitting surface 201b have different light emission angles. Therefore, the first Fresnel lens set on the upper inner surface 311a1 and the second Fresnel lens set on the side inner surface 311a2 can be set independently. The first Fresnel lens and the second Fresnel lens can be independently modulated to ensure that the light emitted from the first light-emitting element 201 has a better focusing effect after passing through the light emission adjustment structure 310.

[0073] Figure 9 This is an enlarged schematic diagram of the fourth type of first light emission adjustment structure provided in the embodiments of this application, with reference to... Figure 9 As shown, the plurality of first light-emitting elements 201 include a first sub-light-emitting element 2011 and a second sub-light-emitting element 2012, wherein the first sub-light-emitting element 2011 is located on the side of the second sub-light-emitting element 2012 near the edge of the light-emitting panel 10; the first light-emitting adjustment structure 310 includes a first inner surface 312 that at least partially covers the first sub-light-emitting element 2011 and a second inner surface 313 that at least partially covers the second sub-light-emitting element 2012; the first inner surface 312 includes a first upper inner surface 312a and a third side inner surface 313. Surface 312b, the second inner surface 313 includes a second upper inner surface 313a and a fourth side inner surface 313b; wherein, the distribution density of Fresnel rings in the first Fresnel lens of the first upper inner surface 312a is greater than or equal to the distribution density of Fresnel rings in the first Fresnel lens of the second upper inner surface 313a; and / or, the distribution density of Fresnel rings in the second Fresnel lens of the third side inner surface 312b is greater than or equal to the distribution density of Fresnel rings in the second Fresnel lens of the fourth side inner surface 313b.

[0074] Among them, reference Figure 9 As shown, a plurality of first light-emitting elements 201 are provided in the first light-emitting area 101. The first light-emitting element 201 includes a first sub-light-emitting element 2011 and a second sub-light-emitting element 2012. The first sub-light-emitting element 2011 and the second sub-light-emitting element 2012 have different positions. Specifically, the first sub-light-emitting element 2011 is located on the side of the second sub-light-emitting element 2012 that is close to the edge of the light-emitting panel 10.

[0075] Further reference Figure 9As shown, the first light-emitting adjustment structure 310 can cover the first sub-light-emitting element 2011 and the second sub-light-emitting element 2012. Specifically, the first light-emitting adjustment structure 310 includes a first inner surface 312 that at least partially covers the first sub-light-emitting element 2011 and a second inner surface 313 that at least partially covers the second sub-light-emitting element 2012. Therefore, the first inner surface 312 can adjust the light emitted by the first sub-light-emitting element 2011 to ensure that the light emitted by the first sub-light-emitting element 2011 is more focused after passing through the first light-emitting adjustment structure 310; the second inner surface 313 can adjust the light emitted by the second sub-light-emitting element 2012 to ensure that the light emitted by the second sub-light-emitting element 2012 is more focused after passing through the first light-emitting adjustment structure 310. By setting the first inner surface 312 and the second inner surface 313, the first light emission adjustment structure 310 can effectively modulate the emitted light of multiple first light-emitting elements 201, improve the light emission brightness of the first light-emitting area 101, and at the same time avoid light leakage at the edge gap of the light-emitting panel 10.

[0076] For details, please refer to Figure 9 As shown, the first inner surface 312 includes a first upper inner surface 312a and a third side inner surface 312b, and the second inner surface 313 includes a second upper inner surface 313a and a fourth side inner surface 313b. Wherein, combined with Figure 9 As shown, the first upper inner surface 312a is located near the side of the first sub-light-emitting element 2011 away from the driving substrate 600. In other words, the first upper inner surface 312a corresponds to the front light-emitting side of the first sub-light-emitting element 2011, and can converge and adjust the light emitted from the front light-emitting side of the first sub-light-emitting element 2011. The third inner surface 312b is connected to the first upper inner surface 312a, therefore the third inner surface corresponds to the side light-emitting surface of the first sub-light-emitting element 2011, and can converge and adjust the light emitted from the side light-emitting side of the first sub-light-emitting element 2011. Similarly, refer to... Figure 9 As shown, the second upper inner surface 313a is located near the side of the second sub-light-emitting element 2012 away from the driving substrate 600. In other words, the second upper inner surface 313a corresponds to the front light-emitting side of the second sub-light-emitting element 2012, and can converge and adjust the light emitted from the front light-emitting side of the second sub-light-emitting element 2012. The fourth side inner surface 313b is connected to the second upper inner surface 313a, therefore the fourth side inner surface 313b corresponds to the side light-emitting surface of the second sub-light-emitting element 2012, and can converge and adjust the light emitted from the side light-emitting side of the second sub-light-emitting element 2012.

[0077] Furthermore, since the first sub-light-emitting element 2011 is located on the side of the second sub-light-emitting element 2012 closer to the edge of the light-emitting panel 10, the first sub-light-emitting element 2011 is more likely to leak light at the gap at the edge of the light-emitting panel 10 compared to the second sub-light-emitting element 2012. In other words, the first sub-light-emitting element 2011 has a poorer light emission effect than the second sub-light-emitting element 2012. Therefore, it is necessary to use the first light emission adjustment structure 310 to adjust the light emission effect of the first sub-light-emitting element 2011 to a greater extent, so as to ensure that the light emitted by the first sub-light-emitting element 2011 has a better convergence effect after adjustment.

[0078] Specifically, by adjusting the distribution density of the Fresnel rings in the first Fresnel lens on the first upper inner surface 312a to be greater than or equal to the distribution density of the Fresnel rings in the first Fresnel lens on the second upper inner surface 313a, combined with the converging effect of the Fresnel lens on transmitted light, it can ensure that the first light-emitting adjustment structure 310 adjusts the light emission of the first sub-light-emitting element 2011 and the second sub-light-emitting element 2012 respectively. Furthermore, it can also ensure that the first light-emitting adjustment structure 310 has a better light emission modulation effect on the first sub-light-emitting element 2011, improving the light emission effect of the first sub-light-emitting element 2011 and avoiding or reducing light leakage at the edge gaps of the light-emitting panel 10. Furthermore, by adjusting the distribution density of the Fresnel rings in the second Fresnel lens on the third inner surface 312b to be greater than or equal to the distribution density of the Fresnel rings in the second Fresnel lens on the fourth inner surface 313b, it can also improve the light emission effect of the first sub-light-emitting element 2011 and avoid or reduce light leakage at the edge gaps of the light-emitting panel 10. Furthermore, the distribution density of the Fresnel rings in the first Fresnel lens on the first upper inner surface 312a can be adjusted to be greater than or equal to the distribution density of the Fresnel rings in the first Fresnel lens on the second upper inner surface 313a, while the distribution density of the Fresnel rings in the second Fresnel lens on the third inner surface 312b can be adjusted to be greater than or equal to the distribution density of the Fresnel rings in the second Fresnel lens on the fourth inner surface 313b. This can significantly improve the light emission effect of the first sub-light-emitting element 2011 and prevent or reduce light leakage at the edge gaps of the light-emitting panel 10.

[0079] Figure 10 This is an enlarged schematic diagram of the fifth type of first light emission adjustment structure provided in the embodiments of this application, with reference to... Figure 10As shown, the plurality of first light-emitting elements 201 include a first sub-light-emitting element 2011 and a second sub-light-emitting element 2012. The first sub-light-emitting element 2011 is located on the side of the second sub-light-emitting element 2012 near the edge of the light-emitting panel 10. The first sub-light-emitting element 2011 includes a first upper light-emitting surface 2011a and a third side light-emitting surface 2011b, and the second sub-light-emitting element 2012 includes a second upper light-emitting surface 2012a and a fourth side light-emitting surface 2012b. The first light-emitting adjustment structure 310 includes a first inner surface 312 that at least partially covers the first sub-light-emitting element 2011 and at least partially covers the second sub-light-emitting element 2012. The second inner surface 313; the first inner surface 312 includes a first upper inner surface 312a and a third side inner surface 312b, and the second inner surface 313 includes a second upper inner surface 313a and a fourth side inner surface 313b; wherein, the minimum distance between the first upper inner surface 312a and the first upper light-emitting surface 2011a is less than or equal to the minimum distance between the second upper inner surface 313a and the second upper light-emitting surface 2012a; and / or, the minimum distance between the third side inner surface 312b and the third side light-emitting surface 2011b is less than or equal to the minimum distance between the fourth side inner surface 313b and the fourth side light-emitting surface 2012b.

[0080] The closer the inner surface of the first light-emitting adjustment structure 310 is to the first light-emitting element 201, the more obvious the focusing adjustment effect of the first light-emitting adjustment structure 310 on the light emitted from the first light-emitting element 201. Specifically, the minimum distance between the first upper inner surface 312a and the first upper light-emitting surface 2011a is less than or equal to the minimum distance between the second upper inner surface 313a and the second upper light-emitting surface 2012a. Combined with the focusing effect of the Fresnel lens on the transmitted light, this ensures that the first light-emitting adjustment structure 310 adjusts the light emission of the first sub-light-emitting element 2011 and the second sub-light-emitting element 2012 respectively. Furthermore, it also ensures that the first light-emitting adjustment structure 310 has a better light emission modulation effect on the first sub-light-emitting element 2011, avoiding or reducing light leakage at the edge gaps of the light-emitting panel 10. Furthermore, the minimum distance between the third inner surface 312b and the third light-emitting surface 2011b can be less than or equal to the minimum distance between the fourth inner surface 313b and the fourth light-emitting surface 2012b. This also ensures that the first light-emitting adjustment structure 310 has a better light-emitting modulation effect on the first sub-light-emitting element 2011, avoiding or reducing light leakage at the edge gaps of the light-emitting panel 10. Alternatively, the minimum distance between the first upper inner surface 312a and the first upper light-emitting surface 2011a can be less than or equal to the minimum distance between the second upper inner surface 313a and the second upper light-emitting surface 2012a. Simultaneously, adjusting the minimum distance between the third inner surface 312b and the third light-emitting surface 2011b to be less than or equal to the minimum distance between the fourth inner surface 313b and the fourth light-emitting surface 2012b further ensures that the first light-emitting adjustment structure 310 has a better light-emitting modulation effect on the first sub-light-emitting element 2011, avoiding or reducing light leakage at the edge gaps of the light-emitting panel 10.

[0081] Continue to refer to Figures 1-4 As shown, the light-emitting panel 10 also includes a plurality of second light-emitting elements 202 disposed in the second light-emitting area 102; the light-emitting panel 10 also includes a plurality of reflective units 203, and a reflective unit 203 is disposed between at least two adjacent second light-emitting elements 202.

[0082] For details, please refer to Figure 2 As shown, the light-emitting element 200 provided in the light-emitting panel 10 also includes a second light-emitting element 202, which is disposed in the second light-emitting area 102. The first light-emitting element 201 is used to ensure the light-emitting effect of the first light-emitting area 101, and the second light-emitting element 202 is used to ensure the light-emitting effect of the second light-emitting area 102.

[0083] Further reference Figure 2As shown, the light-emitting panel 10 also includes multiple reflective units 203. The reflective units 203 are disposed between two adjacent second light-emitting elements 202. Thus, when light emitted from the second light-emitting element 202 reaches the reflective unit 203, it can be reflected and emitted back towards the light-emitting side of the light-emitting panel 10, ensuring the light-emitting effect of the light-emitting panel 10. Furthermore, the reflective units 203 can also block light crosstalk between two adjacent second light-emitting elements 202, which is beneficial for improving the light emission contrast of the light-emitting panel 10.

[0084] Based on the above embodiments, as a feasible implementation method, refer to Figure 3 As shown, in order to avoid crosstalk between two adjacent first light-emitting elements 201 and to ensure the light-emitting effect of the first light-emitting element 201 in the first light-emitting area 101, a reflection unit 203 can also be set between two adjacent first light-emitting elements 201.

[0085] Furthermore, as another possible implementation method, refer to Figure 2 and Figure 4 As shown, since the first light emission adjustment structure 310 can effectively modulate the light emitted by the first light-emitting element 201, a reflection unit 203 does not need to be set between two adjacent first light-emitting elements 201 in this light-emitting panel 10. Furthermore, not setting a reflection unit 203 between two adjacent first light-emitting elements 201 provides more space for the arrangement of the first light-emitting elements 201, allowing for an increase in the number of first light-emitting elements 201 in the first light-emitting area 101.

[0086] Figure 11 yes Figure 1 A schematic diagram of the fourth section along section line A-A', see reference. Figure 11 As shown, the reflection unit 203 includes a first reflection unit 2031 and a second reflection unit 2032. The first reflection unit 2031 is disposed in the first light-emitting area 101 and located between two adjacent first light-emitting elements 201. The second reflection unit 2032 is disposed in the second light-emitting area 102 and located between two adjacent second light-emitting elements 202. Along the light emission direction of the first light-emitting element 201, the height of the first reflection unit 2031 is greater than the height of the second reflection unit 2032.

[0087] Specifically, the reflective unit 203 includes a first reflective unit 2031 and a second reflective unit 2032. The first reflective unit 2031 is located in the first light-emitting area 101 and is disposed between two adjacent first light-emitting elements 201. By reflecting the lateral light emitted by the first light-emitting elements 201, the brightness of the first light-emitting area 101 can be improved. The second reflective unit 2032 is located in the second light-emitting area 102 and is disposed between two adjacent second light-emitting elements 202. By reflecting the lateral light emitted by the second light-emitting elements 202, the brightness of the second light-emitting area 102 can be improved.

[0088] Furthermore, since the first light-emitting area 101 is provided with a first light-emitting adjustment structure 310, and the first light-emitting adjustment structure 310 can adjust the light-emitting effect of the first light-emitting element 201, it ensures that the light emitted by the first light-emitting element 201 has a better converging effect than the light emitted by the second light-emitting element 202. Therefore, the first reflection unit 2031 and the second reflection unit 2032 can be configured differently according to the light-emitting effect of different light-emitting elements 200. Specifically, since the light emitted by the first light-emitting element 201 after passing through the first light-emitting adjustment structure 310 is more focused, that is, the angle between the light emitted by the first light-emitting element 201 after passing through the first light-emitting adjustment structure 310 and the thickness direction of the light-emitting panel is smaller, in order to ensure that the first reflection unit 2031 can receive the side light emitted by the first light-emitting element 201 after passing through the first light-emitting adjustment structure 310, the height of the first reflection unit 2031 can be set to be greater than the height of the second reflection unit 2032 along the light-emitting direction of the first light-emitting element 201. This ensures that the first reflection unit 2031 can adjust the side light emitted by the first light-emitting element 201 after passing through the first light-emitting adjustment structure 310, and the second reflection unit 2032 can adjust the side light emitted by the second light-emitting element 202, thereby better ensuring the light emission effect of the light-emitting panel 10.

[0089] Continue to refer to Figure 11 As shown, the reflection unit 203 includes a first reflection unit 2031 and a second reflection unit 2032. The first reflection unit 2031 is disposed in the first light-emitting area 101 and located between two adjacent first light-emitting elements 201. The second reflection unit 2032 is disposed in the second light-emitting area 102 and located between two adjacent second light-emitting elements 202. The first light-emitting adjustment structure 310 also includes a plurality of second clearance grooves 314, which cover the first reflection unit 2031.

[0090] Further reference Figure 11As shown, the reflective unit 203 includes a first reflective unit 2031 and a second reflective unit 2032, wherein the first reflective unit 2031 and the first light-emitting element 201 are both located in the first light-emitting area 101. Simultaneously, the light-emitting panel 10 also provides a first light-emitting adjustment structure 310 in the first light-emitting area 101. The first light-emitting adjustment structure 310 includes a plurality of first clearance slots 311 for covering the first light-emitting element 201, and also includes a plurality of second clearance slots 314 for covering the first reflective unit 2031.

[0091] Specifically, the first avoidance groove 311 and the second avoidance groove 314 can respectively protect the structure of the first light-emitting element 201 and the first reflective unit 203. On the other hand, the first light-emitting adjustment structure 310 can be transferred to the light-emitting panel 10 after the first avoidance groove 311 and the second avoidance groove 314 are prepared. Therefore, the transfer accuracy of the first light-emitting adjustment structure 310 can be ensured by the first avoidance groove 311 and the second avoidance groove 314, thus ensuring the structural stability and reliability of the light-emitting panel 10.

[0092] Continue to refer to Figure 11 As shown, along the light emission direction of the first light-emitting element 201, the height of the first reflective unit 2031 is greater than the height of the first light-emitting element 201, and the maximum groove depth of the second clearance groove 314 is greater than the maximum groove depth of the first clearance groove 311.

[0093] Further reference Figure 11 As shown, the first light emission adjustment structure 310 adjusts the emitted light of the first light-emitting element 201 to ensure that the emitted light of the first light-emitting element 201 after passing through the first light emission adjustment structure 310 is more focused. That is, the angle between the emitted light of the first light-emitting element 201 after passing through the first light emission adjustment structure 310 and the thickness direction of the light-emitting panel is smaller. Therefore, in order to ensure that the first reflection unit 2031 can receive the lateral light emitted by the first light-emitting element 201 after passing through the first light emission adjustment structure 310, the height of the first reflection unit 2031 can be adjusted to be greater than the height of the first light-emitting element 201. This ensures that the first reflection unit 2031 can reflect the light emitted by the first light-emitting element 201 and ensure the luminous brightness of the first light-emitting area 101.

[0094] Further reference Figure 11 As shown, since the height of the first reflective unit 2031 is greater than the height of the first light-emitting element 201, the maximum slot depth of the second recess 314 in the first light-emitting adjustment structure 310 is greater than the maximum slot depth of the first recess 311. This ensures that the first recess 311 can completely accommodate the first light-emitting element 201, and the second recess 314 can completely accommodate the first reflective unit 2031.

[0095] Continue to refer to Figure 2 , Figures 5-11 As shown, the surface of the first light-emitting adjustment structure 310 on the side away from the first light-emitting element 201 includes a plane.

[0096] Further reference Figure 2 , Figures 5-11 As shown, please refer to the following for details. Figure 11 The area indicated by the middle arrow a7 includes a flat surface on the side of the first light-emitting adjustment structure 310 away from the first light-emitting element 201. This ensures the flatness of the first light-emitting adjustment structure 310, which is beneficial for setting other film structures on the side of the first light-emitting adjustment structure 310 away from the light-emitting element 200.

[0097] Continue to refer to Figure 2 and Figure 11 As shown, the distance L between two adjacent first light-emitting elements 201 satisfies L≤6mm.

[0098] For example, in the first light-emitting area 101, the distance L between two adjacent first light-emitting elements 201 satisfies: L ≤ 6mm. L can be any value among 1mm, 2mm, 4mm, 5.5mm, or 6mm, and this application does not limit the specific value. Therefore, in the area where the first light-emitting adjustment structure 310 is set, when the distance between two adjacent first light-emitting elements 201 is less than or equal to 6mm, the adjustment effect of the Fresnel lens set in the first light-emitting adjustment structure 310 is more obvious, which can better ensure the light-emitting effect of the light-emitting panel 10.

[0099] Figure 12 This is a schematic diagram illustrating the fabrication process of another light-emitting panel provided in an embodiment of this application. Figure 13 This is an enlarged schematic diagram of the first type of second light emission adjustment structure provided in the embodiments of this application, with reference to... Figure 3 , Figure 4 , Figure 12 and Figure 13As shown, the light emission adjustment structure 300 includes a second light emission adjustment structure 320. The second light emission adjustment structure 320 includes an incident light adjustment surface 320a facing the first light-emitting element 201 and an emitting light adjustment surface 320b facing away from the first light-emitting element 201. The incident light adjustment surface 320a includes a first incident light adjustment surface portion 320a1, and the emitting light adjustment surface 320b includes a first emitting light adjustment surface portion 320b1. Along the light emission direction of the first light-emitting element 201, the first incident light adjustment surface portion 320a1 covers at least one first light-emitting element 201, and the first emitting light adjustment surface portion 320b1 and the first incident light adjustment surface portion 320a1 at least partially overlap. The first incident light adjustment surface portion 320a1 is provided with a plurality of reverse prisms, and the first emitting light adjustment surface portion 320b1 is provided with a plurality of corner prisms.

[0100] Among them, reference 3 and Figure 4 As shown, the light emission adjustment structure 300 includes a second light emission adjustment structure 320, which includes an incident light adjustment surface 320a and an emitted light adjustment surface 320b. The incident light adjustment surface 320a is located on the side of the second light emission adjustment structure 320 closer to the first light-emitting element 201, and the emitted light adjustment surface 320b is located on the side of the second light emission adjustment structure farther from the first light-emitting element 201. The second light emission adjustment structure 320 can adjust the emitted light from the first light-emitting element 201 through the incident light adjustment surface 320a and the emitted light adjustment surface 320b, thereby increasing the luminous brightness of the first light-emitting region 101.

[0101] Specifically, the light-incident adjustment surface 320a includes a first light-incident adjustment surface portion 320a1. Along the light-emitting direction of the first light-emitting element 201, the first light-incident adjustment surface portion 320a1 covers at least one first light-emitting element 201. Therefore, the first light-incident adjustment surface portion 320a1 can adjust the light emitted from the first light-emitting element 201. Specifically, the first light-incident adjustment surface portion 320a1 is provided with multiple reverse prisms (see reference...). Figure 13 The area indicated by b2 (in the diagram) can be diffused by the inverted prism. Furthermore, the light-emitting adjustment surface 320b includes a first light-emitting adjustment surface portion 320b1. Along the light-emitting direction of the first light-emitting element 201, the first light-emitting adjustment surface portion 320b1 at least partially overlaps with the first incident light adjustment surface portion 320a1. Therefore, the first light-emitting adjustment surface portion 320b1 can further modulate the light adjusted by the first incident light adjustment surface portion 320a1. Specifically, the first light-emitting adjustment surface portion 320b1 is provided with multiple corner prisms (refer to...). Figure 13The area indicated by b3 can be adjusted by setting a corner prism to ensure that the light diffused by the reverse prism is emitted towards the edge area of ​​the light-emitting panel 10. This can improve the brightness of the light-emitting panel 10 near the edge area, improve the problem of low brightness caused by insufficient mutual compensation between the light-emitting elements 200 in the edge area of ​​the light-emitting panel 10, and ensure the overall light-emitting effect of the light-emitting panel 10.

[0102] Optional, see reference Figure 12 As shown, the fabrication process of the light-emitting panel 10, including the second light adjustment structure 320, is as follows: First, refer to... Figure 12 As shown in step a, a first light-emitting element 201 is fabricated in the first light-emitting region 101, etc. (Refer to...) Figure 12 As shown in step b, a second light-emitting adjustment structure 320 is provided. The second light-emitting adjustment structure 320 includes an incident light adjustment surface 320a and an exiting light adjustment surface 320b. A reverse prism is disposed on the incident light adjustment surface 320a, and a corner prism is disposed on the exiting light adjustment surface 320b. Finally, refer to... Figure 12 As shown in step c, the second light-emitting adjustment structure 320 is placed on the light-emitting side of the first light-emitting element 201. Light is diffused by a reverse prism, and the light is adjusted towards the edge by a corner prism, thereby increasing the light emission from the edge of the light-emitting panel 10. This can be understood as the second light-emitting adjustment structure 320 being a structure first fabricated using other processes and then placed on one side of the first light-emitting element 201. Therefore, when designing the reverse and corner prisms on the surface of the second light-emitting adjustment structure 320, the related fabrication processes do not damage the light-emitting element 200, and thus do not affect the structural stability of the light-emitting panel 10.

[0103] Figure 14 yes Figure 13 A top view of the first incident light adjustment surface portion in the second light-emitting adjustment structure. Figure 15 yes Figure 13 A top view of the first light-emitting adjustment surface portion in the second light-emitting adjustment structure. (Continue to refer to...) Figures 13-15 As shown, the reverse prism extends along the first direction X1, and multiple reverse prisms are arranged along the second direction X2; the corner prism extends along the first direction X1, and multiple corner prisms are arranged along the second direction X2; the first direction X1 and the second direction X2 intersect, and both intersect with the light emission direction of the first light-emitting element 201.

[0104] Specifically, the first incident light adjustment surface portion 320a1 includes multiple reverse prisms, and the reverse prisms extend along a first direction X1, while the multiple reverse prisms are arranged along a second direction X2. Combined with... Figure 13 and Figure 14As shown, a reverse prism can be understood as multiple prism structures arranged in an array along a one-dimensional plane, thus ensuring the consistency of light emitted along the first direction X1 after being adjusted by the reverse prism. Specifically, the first light-emitting adjustment surface 320b1 includes multiple corner prisms, which extend along the first direction X1 and are arranged along the second direction X2. Figure 13 and Figure 15 As shown, a corner prism can be understood as multiple prism structures arranged in an array in one dimension, which can ensure that the light rays adjusted by the corner prism have consistent output along the first direction X1.

[0105] In summary, the light emitted after the reverse prism and the angle adjustment has a consistent light output in the first direction X1, which can ensure that the light emission effect of the first light emission area 101 is improved and the light emission brightness of the first light emission area 101 is guaranteed.

[0106] Continue to refer to Figure 13 As shown, the cross-sectional shape of the reverse prism is an isosceles triangle, and the angle between the first leg d1 and the second leg d2 in the isosceles triangle is the first vertex c1. The first vertex c1 faces the first light-emitting element 201 and the range of the first vertex c1 is 80°-100°. The cross-sectional shape of the corner prism includes a right triangle, and the angle between the first leg d3 and the hypotenuse d4 in the right triangle is the second vertex c2. The second vertex c2 faces away from the first light-emitting element 201 and the range of the second vertex c2 is 60°-75°.

[0107] For details, please refer to Figure 13 As shown, the cross-sectional shape of the reverse prism disposed on the first light-incident adjustment surface portion 320a1 can be an isosceles triangle, wherein the isosceles triangle includes a first vertex angle c1, and the first vertex angle c1 is the angle between the first leg d1 and the second leg d2 of the isosceles triangle. Specifically, the angle range for the first vertex angle c1 can be between 80° and 100°. For example, the first vertex angle c1 can be any value among 80°, 90°, 95° or 100°. This application does not limit the specific value of the first vertex angle c1, and it can be adaptively adjusted according to actual needs. By setting the cross-sectional shape of the reverse prism to an isosceles triangle, it can be ensured that the light adjustment of the surrounding first light-emitting element 201 by the reverse prism is balanced, and the light generated by the first light-emitting element 201 can be effectively diffused into the second light-emitting adjustment structure 320.

[0108] Further reference Figure 13As shown, the cross-sectional shape of the corner prism disposed on the first light-emitting adjustment surface 320b1 can be a right-angled triangle, wherein the right-angled triangle includes a second vertex c2, and the second vertex c2 is the angle between the first leg d3 and the hypotenuse d4 of the right-angled triangle. Specifically, the angle range for the second vertex c2 can be between 60° and 75°. For example, the second vertex c2 can be any value among 60°, 70°, or 75°. This application does not limit the specific value of the first vertex c1, and it can be adaptively adjusted according to actual needs. By setting the cross-sectional shape of the corner prism to a right-angled triangle, the light transmitted to the second light-emitting adjustment structure 320 can be effectively adjusted towards the edge area of ​​the light-emitting area, improving the light emission brightness of the light-emitting panel 10 near the edge and ensuring the overall light emission effect of the light-emitting panel 10.

[0109] Figure 16 This is an enlarged schematic diagram of the second type of second light emission adjustment structure provided in the embodiments of this application, with reference to... Figure 16 As shown, the first incident light adjustment surface portion 320a1 includes a first incident light adjustment region 320a11 and a second incident light adjustment region 320a12. The first incident light adjustment region 320a11 is located on the side of the second incident light adjustment region 320a12 near the edge of the light-emitting panel 10. The distribution density of the reverse prism in the first incident light adjustment region 320a11 is greater than or equal to the distribution density of the reverse prism in the second incident light adjustment region 320a12. And / or, the first light emission adjustment surface portion 320b1 includes a first light emission adjustment region 320b11 and a second light emission adjustment region 320b12. The first light emission adjustment region 320b11 is located on the side of the second light emission adjustment region 320b12 near the edge of the light-emitting panel 10. The distribution density of the corner prism in the first light emission adjustment region 320b11 is greater than or equal to the distribution density of the corner prism in the second light emission adjustment region 320b12.

[0110] In order to better adjust the light emission brightness near the edge of the light emission area in the light emission panel 10, the surface structure of the second light emission adjustment structure 320 used to adjust the light transmission path can be further adjusted. Specifically, the first light incident adjustment surface portion 320a1 and / or the first light emission adjustment surface portion 320b1 are further adjusted to further improve the light emission brightness of the light emission area near the edge of the light emission panel 10, thereby increasing the brightness of the edge area of ​​the light emission panel 10.

[0111] For details, please refer to Figure 16As shown, the first incident light adjustment surface portion 320a1 includes a first incident light adjustment region 320a11 and a second incident light adjustment region 320a12, wherein the first incident light adjustment region 320a11 is located on the side of the second incident light adjustment region 320a12 closer to the edge of the light-emitting panel 10. To ensure effective adjustment of the emitted light from the first light-emitting element 201 closer to the edge, the distribution density of the corner prisms in the first incident light adjustment region 320b11 can be adjusted to be greater than or equal to the distribution density of the corner prisms in the second incident light adjustment region 320b12. The distribution density of the reverse prisms can be understood as the number of reverse prisms per unit area. Adjusting the distribution density of the corner prisms in the first incident light adjustment region 320b11 to be equal to the distribution density of the corner prisms in the second incident light adjustment region 320b12 can reduce the manufacturing difficulty of the first incident light adjustment surface portion 320a1. By adjusting the distribution density of the corner prisms in the first light-emitting adjustment area 320b11 to be greater than that in the second light-emitting adjustment area 320b12, it can be ensured that the first light-emitting adjustment area 320a11 can better adjust the light emitted from the first light-emitting element 201 into the second light-emitting adjustment structure 320.

[0112] For details, please refer to Figure 16 As shown, the first light-emitting adjustment surface portion 320b1 includes a first light-emitting adjustment region 320b11 and a second light-emitting adjustment region 320b12, wherein the first light-emitting adjustment region 320b11 is located on the side of the second light-emitting adjustment region 320b12 near the edge of the light-emitting panel 10. To ensure increased brightness in the light-emitting area near the edge of the light-emitting panel 10, the distribution density of the corner prisms in the first light-emitting adjustment region 320b11 can be adjusted to be greater than or equal to the distribution density of the corner prisms in the second light-emitting adjustment region 320b12. The distribution density of the corner prisms can be understood as the number of corner prisms per unit area. Adjusting the distribution density of the corner prisms in the first light-emitting adjustment region 320b11 to be equal to the distribution density of the corner prisms in the second light-emitting adjustment region 320b12 can reduce the manufacturing difficulty of the first light-emitting adjustment surface portion 320b1. By adjusting the distribution density of the corner prisms in the first light-emitting adjustment area 320b11 to be greater than that in the second light-emitting adjustment area 320b12, more light can be emitted from the first light-emitting adjustment area 320b11, thereby increasing the luminous brightness of the light-emitting panel 10 in the edge area.

[0113] Further reference Figure 16As shown, while adjusting the distribution density of the reverse prism in the first light-incident adjustment region 320a11 to be greater than or equal to the distribution density of the reverse prism in the second light-incident adjustment region 320a12, the distribution density of the corner prism in the first light-out adjustment region 320b11 can also be adjusted to be greater than or equal to the distribution density of the corner prism in the second light-out adjustment region 320b12. Therefore, the arrangement of the second light-out adjustment structure 320 is diverse and can be adaptively adjusted according to actual needs.

[0114] Continue to refer to Figure 3 and Figure 4 As shown, the light-emitting panel 10 also includes a plurality of second light-emitting elements 202 disposed in the second light-emitting area 102; the light-incident adjustment surface 320a also includes a second light-incident adjustment surface portion 320a2, and the light-emitting adjustment surface 320b also includes a second light-emitting adjustment surface portion 320b2. Along the light-emitting direction of the second light-emitting element 202, the second light-incident adjustment surface portion 320a2 covers at least one second light-emitting element 202, and the second light-emitting adjustment surface portion 320b2 and the second light-incident adjustment surface portion 320a2 at least partially overlap; the second light-incident adjustment surface portion 320a2 is provided with a plurality of reverse prisms, and the second light-emitting adjustment surface portion 320b2 includes a plane.

[0115] For details, please refer to Figure 3 and Figure 4 As shown, the light-emitting element 200 provided in the light-emitting panel 10 also includes a second light-emitting element 202, which is disposed in the second light-emitting area 102. The first light-emitting element 201 is used to ensure the light-emitting effect of the first light-emitting area 101, and the second light-emitting element 202 is used to ensure the light-emitting effect of the second light-emitting area 102.

[0116] In the second light emission adjustment structure 320, the light incident adjustment surface 320a further includes a second light incident adjustment surface portion 320a2. Along the light emission direction of the second light-emitting element 202, the second light incident adjustment surface portion 320a2 covers at least one second light-emitting element 202, and multiple reverse prisms are provided in the second light incident adjustment surface portion 320a2. Therefore, the light emitted from the second light-emitting element 202 can also be modulated by the second light emission adjustment structure 320. Through the multiple reverse prism structure, the light emitted from the second light-emitting element 202 can be diffused, and combined with the light emission adjustment panel 320b, the brightness of the first light-emitting area 101 and the second light-emitting area 102 can be balanced.

[0117] Furthermore, in the second light-emitting adjustment structure 320, the light-emitting adjustment surface 320b further includes a second light-emitting adjustment surface portion 320b2, wherein along the light-emitting direction of the second light-emitting element 202, the second light-emitting adjustment surface portion 320b2 at least partially overlaps with the second light-incident adjustment surface portion 320a2, and the second light-emitting adjustment surface portion 320b2 includes a plane. In this way, it can be ensured that the light emitted from the second light-emitting area 102 in the second light-emitting adjustment structure 320 does not need to be emitted towards the edge region of the light-emitting panel 10, thereby ensuring the luminous brightness of the second light-emitting area 102.

[0118] For details, please refer to Figure 3 and Figure 4 As shown, the distribution density of the reverse prism in the first incident light adjustment surface section 320a1 is greater than or equal to the distribution density of the reverse prism in the second incident light adjustment surface section 320a2.

[0119] Further reference Figure 3 and Figure 4 As shown, the first incident light adjustment surface portion 320a1 located in the first light-emitting region 101 and the second incident light adjustment surface portion 320a2 located in the second light-emitting region 102 can be configured differently. Specifically, the distribution density of the reverse prism in the first incident light adjustment surface portion 320a1 can be adjusted to be greater than or equal to the distribution density of the reverse prism in the second incident light adjustment surface portion 320a2.

[0120] For details, please refer to Figure 4 As shown, adjusting the distribution density of the reverse prism in the first incident light adjustment surface portion 320a1 to be equal to the distribution density of the reverse prism in the second incident light adjustment surface portion 320a2 can reduce the design difficulty of the incident light adjustment surface 320a in the second light output adjustment structure 320 and ensure that the overall structure of the second light output adjustment structure 320 is more regular.

[0121] For details, please refer to Figure 3 As shown, the distribution density of the reverse prism in the first light-incident adjustment surface 320a1 can be adjusted to be greater than that in the second light-incident adjustment surface 320a2, which can ensure that the second light-emitting adjustment structure 320 has a better light-gathering effect at the first light-emitting area 101, and ensure that the light-emitting panel 10 has a better light-gathering effect near the edge area.

[0122] Continue to refer to Figure 3 As shown, the distance L between two adjacent first light-emitting elements 201 satisfies L > 6 mm.

[0123] For example, in the first light-emitting area 101, the distance L between two adjacent first light-emitting elements 201 satisfies the condition that L > 6 mm. L can be any value among 7 mm, 8 mm, 9 mm, 9.5 mm, or 10 mm, and this application does not limit the specific value. Therefore, in the area where the first light-emitting adjustment structure 310 is set, when the distance between two adjacent first light-emitting elements 201 is greater than 6 mm, by setting reverse prisms and corner prisms on both sides of the second light-emitting adjustment structure 320 along the light-emitting direction of the light-emitting element 200, the light-emitting effect of the light-emitting panel 10 can be better guaranteed.

[0124] Figure 17 yes Figure 1 A schematic diagram of the fifth type of section along section line A-A', see reference. Figure 4 and Figure 17 As shown, the light emission adjustment structure 300 includes a first light emission adjustment structure 310 and a second light emission adjustment structure 320. The first light emission adjustment structure 310 includes a plurality of first recessed grooves 311, each recessed groove 311 covering at least one first light-emitting element 201. Each recessed groove 311 includes an inner surface 311a, and at least a portion of the inner surface 311a is provided with a Fresnel lens. The second light emission adjustment structure 320 is located on the side of the first light emission adjustment structure 310 away from the first light-emitting element 201. The second light emission adjustment structure 320 includes an incident light adjustment surface 320a facing the first light-emitting element 201 and a back light adjustment surface 320a. A light-emitting adjustment surface 320b is provided on the side away from the first light-emitting element 201; the light-incident adjustment surface 320a includes a first light-incident adjustment surface portion 320a1, and the light-emitting adjustment surface 320b includes a first light-emitting adjustment surface portion 320b1. Along the light-emitting direction of the first light-emitting element 202, the first light-incident adjustment surface portion 320a1 covers at least one first light-emitting element 201, and the first light-emitting adjustment surface portion 320b1 and the first light-incident adjustment surface portion 320a1 at least partially overlap; the first light-incident adjustment surface portion 320a1 is provided with a plurality of reverse prisms, and the first light-emitting adjustment surface portion 320b1 is provided with a plurality of corner prisms.

[0125] For details, please refer to Figure 4 and Figure 17 As shown, the light-emitting panel 10 includes a first light-emitting adjustment structure 310 and a second light-emitting adjustment structure 320. The first light-emitting adjustment structure 310 and the second light-emitting adjustment structure 320 can modulate the emitted light of the first light-emitting element 201, ensuring the light-emitting effect of the first light-emitting area 101 and the overall light-emitting effect of the light-emitting panel 10.

[0126] For details, please refer to Figure 4 and Figure 17As shown, in the first light-emitting adjustment structure 310, the first recess 311 covers the first light-emitting element 201. The surface of the first recess 311 near the first light-emitting element 201 is used to adjust the light emitted from the first light-emitting element 201. Therefore, the surface of the first recess 311 near the first light-emitting element 201 can be non-planar, thereby ensuring an increase in the luminous intensity of the first light-emitting area 101. Specifically, in order to ensure the adjustment of the light emitted from the first light-emitting element 201, the inner surface 311a of the first recess 311 is designed to be non-planar. For example, refer to... Figure 4 and Figure 17 As shown, at least a portion of the inner surface 311a is provided with a Fresnel lens.

[0127] Further reference Figure 4 and Figure 17 As shown, the second light-emitting adjustment structure 320 includes an incident light adjustment surface 320a and an emitted light adjustment surface 320b. The incident light adjustment surface 320a is located on the side of the second light-emitting adjustment structure 320 closer to the first light-emitting element 201, and the emitted light adjustment surface 320b is located on the side of the second light-emitting adjustment structure away from the first light-emitting element 201. The second light-emitting adjustment structure 320 can adjust the emitted light from the first light-emitting element 201 through the incident light adjustment surface 320a and the emitted light adjustment surface 320b, thereby improving the luminous brightness of the first light-emitting area 101. Specifically, the incident light adjustment surface 320a includes a first incident light adjustment surface portion 320a1. Along the light-emitting direction of the first light-emitting element 201, the first incident light adjustment surface portion 320a1 covers at least one first light-emitting element 201. Therefore, the first incident light adjustment surface portion 320a1 can adjust the light emitted from the first light-emitting element 201. Specifically, the first incident light adjustment surface portion 320a1 is provided with multiple reverse prisms, which can diffuse the light emitted from the first light-emitting element 201. Further, the emitted light adjustment surface 320b includes a first emitted light adjustment surface portion 320b1. Along the light emission direction of the first light-emitting element 201, the first emitted light adjustment surface portion 320b1 at least partially overlaps with the first incident light adjustment surface portion 320a1. Therefore, the first emitted light adjustment surface portion 320b1 can further modulate the light adjusted by the first incident light adjustment surface portion 320a1. Specifically, the first light-emitting adjustment surface 320b1 is provided with multiple corner prisms. The corner prisms can adjust the light diffused by the reverse prism, ensuring that the light is emitted towards the edge area of ​​the light-emitting panel 10. This can improve the light brightness of the light-emitting panel 10 near the edge area, improve the problem of low brightness caused by insufficient mutual compensation between the light-emitting elements 200 in the edge area of ​​the light-emitting panel 10, and ensure the overall light-emitting effect of the light-emitting panel 10.

[0128] In summary, the light-emitting panel 10 provided in this application embodiment can simultaneously provide a first light-emitting adjustment structure 310 and a second light-emitting adjustment structure 320, which can effectively modulate the light emitted from the first light-emitting element 201, improve the luminous efficiency of the first light-emitting area 101, and ensure the luminous effect of the first light-emitting area 101.

[0129] Continue to refer to Figure 4 and Figure 17 As shown, in the light emission direction of the first light-emitting element 201, the first light-incident adjustment surface portion 320a1 covers the first light-emitting adjustment structure 310, and the first light-emitting adjustment surface portion 320b1 covers the first light-emitting adjustment structure 310.

[0130] For details, please refer to Figure 4 and Figure 17 As shown, along the light emission direction of the first light-emitting element 201, the first light-incident adjustment surface portion 320a1 of the second light emission adjustment structure 320 covers the first light emission adjustment structure 310, and the first light emission adjustment surface portion 320b1 also covers the first light emission adjustment structure 310. Therefore, the surfaces in the second light emission adjustment structure 320 used for modulating light are all covered by the first light emission adjustment structure 310, which ensures that the light emitted from the first light-emitting element 201 can be effectively modulated by the first light emission adjustment structure 310 and the second light emission adjustment structure 320, thus ensuring the adjustment effect of the light effect, the light emission effect of the first light-emitting area 101, and the light emission effect of the entire light-emitting panel 10.

[0131] Continue to refer to Figure 4 and Figure 17 As shown, the first light-emitting adjustment structure 310 and the second light-emitting adjustment structure 320 are arranged in contact, and the end of the first light-incident adjustment surface portion 320a1 near the edge of the light-emitting panel 10 is suspended.

[0132] For details, please refer to Figure 4 and Figure 17 As shown, the first light-emitting adjustment structure 310 and the second light-emitting adjustment structure 320 are arranged in contact, meaning that the second light-emitting adjustment structure 320 is overlapped and placed on the side of the first light-emitting adjustment structure 310 away from the light-emitting element 200. The first light-emitting adjustment structure 310 and the second light-emitting adjustment structure 320 can provide support for the entire light-emitting panel 10, therefore, referring to... Figure 4 Middle area e1 and Figure 17 As shown in the middle region e2, the end of the first light-incident adjustment surface portion 320a1 near the edge of the light-emitting panel 10 can be suspended.

[0133] For example, Figure 4This is a schematic diagram of the structure of a light-emitting panel in the prior art. In the prior art, the light-emitting panel 10 includes multiple light-emitting elements 200'. In order to ensure the overall structural stability of the light-emitting panel 10', a frame structure 700' is designed in the edge area of ​​the light-emitting panel 10'. Figure 17 Reference Figure 18 , Figure 18 and Figure 2 In comparison, when the light-emitting panel 10 provided in this application embodiment includes a first light-emitting adjustment structure 310 and / or a second light-emitting adjustment structure 320, it is no longer necessary to provide the existing frame structure 700' near the edge of the light-emitting panel 10 to provide support. Therefore, the light-emitting panel 10 provided in this application embodiment can save space in the edge area, allowing for the placement of more light-emitting elements 200 and enabling a narrow bezel design for the entire light-emitting panel 10.

[0134] Continue to refer to Figure 3 As shown, the light-emitting panel 10 also includes a plurality of second light-emitting elements 202 disposed in the second light-emitting area 102; the light-emitting panel 10 also includes a driving substrate 600, which is electrically connected to the first light-emitting element 201 and the second light-emitting element 202 respectively, and is used to provide driving signals for the first light-emitting element 201 and the second light-emitting element 202; at least some of the driving signals of the first light-emitting element 201 are greater than the driving signals of the second light-emitting element 202.

[0135] For details, please refer to Figure 4 As shown, the light-emitting panel 10 includes a first light-emitting area 101 and a second light-emitting area 102. The light-emitting element 200 located in the first light-emitting area 101 is the first light-emitting element 201, and the light-emitting element 200 located in the second light-emitting area 102 is the second light-emitting element 202.

[0136] Because the first light-emitting element 201 is closer to the edge of the light-emitting panel 10, the number of light-emitting elements 200 on the side of the first light-emitting element 201 closest to the edge of the light-emitting panel 10 is smaller, or no additional light-emitting elements 200 are set. Therefore, the number of light-emitting elements 200 around the first light-emitting element 201 that can compensate for each other's brightness is relatively small, resulting in the brightness of the first light-emitting area 101 being weaker than that of the second light-emitting area 102. At the same time, because the first light-emitting element 201 is positioned closer to the edge of the light-emitting panel 10, some of the light emitted by the first light-emitting element 201 will exit through the gap between the first light-emitting element 201 and the edge of the light-emitting panel 10. The gap at the edge can be understood as the boundary between the light-emitting area and the non-light-emitting area of ​​the light-emitting panel 10. Since the gap at the edge of the light-emitting panel 10 is not part of the effective light-emitting area of ​​the light-emitting panel 10, it will reduce the overall light emission efficiency of the first light-emitting element 201. This will also result in the brightness of the first light-emitting area 101 being weaker than that of the second light-emitting area 102, and will also cause light leakage in the edge area of ​​the light-emitting panel 10. Therefore, in order to ensure a balanced luminous effect between the first light-emitting area 101 and the second light-emitting area 102, or to reduce the low luminous efficiency of the first light-emitting element 201 due to its placement, this application sets the driving signal of at least some of the first light-emitting elements 201 in the light-emitting panel 10 to be greater than the driving signal of the second light-emitting element 202. This difference in driving signal settings can increase the luminous brightness of the first light-emitting area 101, ensuring a balanced luminous effect between the first light-emitting area 101 and the second light-emitting area 102, and improving the overall luminous effect of the light-emitting panel.

[0137] Furthermore, in the prior art, in order to improve the light extraction efficiency of the first light-emitting element 201 and compensate for its light extraction loss, the driving signal provided by the driving substrate 600 to the first light-emitting element 201 is significantly stronger than the driving signal provided by the driving substrate 600 to the second light-emitting element 201. However, in this embodiment, by setting the light extraction adjustment structure 310, the light extraction brightness of the first light-emitting region 101 can be improved from a structural perspective. Therefore, the driving signal provided by the driving substrate 600 to the first light-emitting element 201 can be reduced; at least a portion of the driving signal for the first light-emitting element 201 needs to be greater than the driving signal for the second light-emitting element 202. This effectively reduces the power consumption of the driving substrate 600.

[0138] For example, Figures 1-4 This is a schematic diagram of the driving signal provided by the driving substrate to the light-emitting element in the prior art. Figures 1-4 This is a schematic diagram of the driving signals provided by the driving substrate to the light-emitting element in this application, see reference. Figure 19 and Figure 20 As shown, Figure 19 and Figure 20The diagram shows multiple first light-emitting elements 201 and multiple second light-emitting elements 202. The specific number of light-emitting elements 200 in a single light-emitting panel 10 can be adaptively adjusted. Figure 19 and Figure 20 This is for illustrative purposes only. Figure 19 and Figure 20 The values ​​shown on the light-emitting element 200 can be understood as the magnitude or proportional relationship of the driving current provided by the driving substrate 600 to the corresponding light-emitting element 200. Wherein, reference... Figure 19 As shown, in the prior art, by providing different driving currents to the first light-emitting element 201 and the second light-emitting element 202 through the driving substrate 600, the light-emitting effect of the first light-emitting area 101 can be guaranteed. (Comparative Reference) Figure 20 and Figure 19 As shown, the light-emitting panel 10 provided in this application embodiment is provided with a light emission adjustment structure 300. The light emission adjustment structure 300 can modulate the light emission of the first light-emitting element 201. Therefore, the driving substrate 600 can reduce the driving current of the first light-emitting element 201, and can also ensure the light emission effect of the first light-emitting area 101. Therefore, the light-emitting panel 10 provided in this application embodiment has the advantage of low power consumption while ensuring the light emission effect.

[0139] refer to Figure 19 As shown, the light-emitting panel 10 also includes a color conversion layer 510 and a diffusion layer 520 disposed on the side of the light-emitting adjustment structure 300 away from the first light-emitting element 201; the color conversion layer 510 is located between the diffusion layer 520 and the light-emitting adjustment structure 300, or the color conversion layer 510 is located on the side of the diffusion layer 520 away from the light-emitting adjustment structure 300.

[0140] Further reference Figure 20 As shown, the light-emitting panel 10 also includes a color conversion layer 510 and a diffusion layer 520. The diffusion layer 520 can diffuse light and improve the uniformity of light emission from the light-emitting panel 10. The color conversion layer 510 includes color-converting ions (not specifically shown in the figure), such as quantum dots. The color of the light emitted from the light-emitting element 200 can be adjusted by passing through the color conversion layer 510. For example, blue light emitted by the light-emitting element 200 can be converted into white light after passing through the color conversion layer 510.

[0141] The placement of the color conversion layer 510 and the diffusion layer 520 is flexible and can be referenced. Figures 2-4 and Figures 2-4 As shown, the color conversion layer 510 is located on the side of the diffusion layer 520 away from the light emission adjustment structure 300, or as can be seen from... Figure 2 As shown, the color conversion layer 510 is located on the side of the diffusion layer 520 near the light adjustment structure 300.

[0142] Optionally, the light-emitting panel 10 may also include a brightness enhancement film (not specifically shown in the figure), which can further brighten the light emitted by the light-emitting element 200 and improve the light emission effect of the light-emitting panel 10. For the film structure disposed on the side of the light emission adjustment structure 300 away from the light-emitting element 200, it can be adaptively adjusted according to actual needs, and this application does not impose specific limitations on it.

[0143] Optionally, the light-emitting element includes a submicron light-emitting diode.

[0144] The light-emitting elements can include submicron light-emitting diodes (Mini-LEDs). Submicron LEDs are semiconductor electronic components that convert electrical energy into light energy. They are characterized by their small size, long lifespan, rich and varied colors, and low energy consumption, and are widely used. Due to the small size of electronic components such as submicron LEDs, more light-emitting elements can be placed in a light-emitting panel of the same size, which is beneficial for achieving precise light emission control of the panel.
