The light emitting module 1 comprises a substrate 10, a plurality of light emitting units 20 arranged on the substrate 10, and a reflective layer 32 arranged on the substrate 10.

The shape of the hollow hole 320 is an axisymmetric figure, or the shape of the hollow hole 320 is a regular n-polygon, wherein n is a positive integer greater than or equal to 5.

[0035] It should be noted that the substrate 10 includes but is not limited to one of a flexible printed circuit (FPC), a printed circuit board (PCB), or a BT resin (Bismaleimide-Triazine); the light emitting unit 20 includes but is not limited to one of a micro light emitting diode (Mini-LED) or a submillimeter light emitting diode (Mini-LED), wherein the light emitting unit 20 is preferably a micro light emitting diode (Mini-LED), and the size of the light emitting unit 20 is 0.05-0.3 mm; the reflective layer 32 can be attached to one side of the substrate 10 close to the light emitting unit 20 by adhesive (such as silicone, epoxy, rubber, etc.), that is, in this embodiment, the reflective layer 32 is directly attached to the substrate 10.

[0036] It can be understood that in this embodiment, by providing a reflective layer 32 on the substrate 10, the reflective layer 32 includes a plurality of hollow holes 320, one hollow hole 320 corresponds to one light emitting unit 20, and the light emitting unit 20 is located in the hollow hole 320, thereby playing a reflecting role on the light emitted by the light emitting unit 20; and by setting the shape of the hollow hole 320 to be an axisymmetric figure, or the shape of the hollow hole 320 to be a regular n-gon, where n is a positive integer greater than or equal to 5, thereby reducing the gap between the hollow hole 320 and the light emitting unit 20, and further improving the utilization rate of light.

[0037] In an embodiment, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 ; wherein, Figure 2 is a first structure diagram of the light emitting module provided by the embodiment of the present application; Figure 3 is a first top view of the light emitting module provided by the embodiment of the present application; Figure 4 is a second top view of the light emitting module provided by the embodiment of the present application; Figure 5 is a third top view of the light emitting module provided by the embodiment of the present application; Figure 6 is a fourth top view of the light emitting module provided by the embodiment of the present application.

[0039] Specifically, the first direction is represented by X, and the second direction is represented by Y. In this embodiment, the preset angle between the first direction X and the second direction Y is 90°, and the light-emitting module is exemplarily described.

[0040] It can be understood that, by setting the first interval d1 between two adjacent hollow holes 320 along the first direction X to be equal, and the second interval d2 between two adjacent hollow holes 320 along the second direction Y to be equal, wherein the first interval d1 is equal to the second interval d2, that is, the adjacent hollow holes 320 have a certain interval, the light rays emitted by the light-emitting units 20 at different angles can pass through the reflection layer 32 and be emitted uniformly in the light-emitting direction, thereby making each part of the light-emitting module 1 have a uniform brightness performance effect.

[0041] Further, in the embodiment, in the light-emitting unit 20 corresponding to the hollow hole 320, the center of the hollow hole 320 coincides with the center of the light-emitting unit 20, and along the first direction X, the third interval d3 between two adjacent light-emitting units 20 is provided, and in the light-emitting unit 20 corresponding to the hollow hole 320, the fourth interval d4 between the hollow hole 320 and the light-emitting unit 20 is provided; along the second direction Y, the fifth interval d5 between two adjacent light-emitting units 20 is provided, and in the light-emitting unit 20 corresponding to the hollow hole 320, the sixth interval d6 between the hollow hole 320 and the light-emitting unit 20 is provided; wherein when the third interval d3 is less than the fifth interval d5, the fourth interval d4 is less than the sixth interval d6; when the third interval d3 is greater than the fifth interval d5, the fourth interval d4 is greater than the sixth interval d6.

[0042] In an embodiment, referring to Figure 3 , the shape of the hollow hole 320 and the shape of the light-emitting unit 20 are both rectangular, the long side L1 of the hollow hole 320 is parallel to the short side W2 of the light-emitting unit 20, and the short side L2 of the hollow hole 320 is parallel to the long side W1 of the light-emitting unit 20.

[0043] Wherein, along the first direction X, the third interval d3 is between the short sides W2 of two adjacent light emitting units 20, and the fourth interval d4 is between the long side L11 of the first hollow hole 321 and the short side W2 of the light emitting unit 20 corresponding to the first hollow hole 321; along the second direction Y, the fifth interval d5 is between the long sides W1 of two adjacent light emitting units 20, and the sixth interval d6 is between the short side L22 of the second hollow hole 322 and the long side W1 of the light emitting unit 20 corresponding to the second hollow hole 322. The third interval d3 is less than the fifth interval d5 in this embodiment.

[0044] Specifically, the hollow hole 320 includes a plurality of first hollow holes 321 and a plurality of second hollow holes 322, the first hollow holes 321 and the second hollow holes 322 are arranged alternately along the second direction Y, the first hollow holes 321 are arrayed along the first direction X, the second hollow holes 322 are arrayed along the first direction X, one first hollow hole 321 corresponds to one light emitting unit 20, one second hollow hole 322 corresponds to one light emitting unit 20, and the aperture of the second hollow hole 322 is larger than the aperture of the first hollow hole 321.

[0045] Wherein, the shape of the first hollow hole 321, the shape of the second hollow hole 322 and the shape of the light emitting unit 20 are all rectangular, the long side L11 of the first hollow hole 321 is parallel to the short side W2 of the light emitting unit 20, and the short side L22 of the second hollow hole 322 is parallel to the long side W1 of the light emitting unit 20.

[0046] Wherein, along the first direction X, the third interval d3 is between the short sides W2 of two adjacent light emitting units 20, and the fourth interval d4 is between the long side L11 of the first hollow hole 321 and the short side W2 of the light emitting unit 20 corresponding to the first hollow hole 321; along the second direction Y, the fifth interval d5 is between the long sides W1 of two adjacent light emitting units 20, and the sixth interval d6 is between the short side L22 of the second hollow hole 322 and the long side W1 of the light emitting unit 20 corresponding to the second hollow hole 322. The third interval d3 is less than the fifth interval d5 in this embodiment.

[0047] It can be understood that when the third distance d3 is less than the fifth distance d5, by setting the fourth distance d4 to be less than the sixth distance d6, the first distance d1 is equal to the second distance d2, that is, the area of the reflecting layer 32 between the two adjacent light emitting units 20 is equal, thereby compensating for the reflectivity difference problem caused by the third distance d3 being less than the fifth distance d5. Therefore, the embodiment can control the size and shape of the hollow hole 320 to control the reflectivity, thereby improving the utilization of light without affecting other performance of the light emitting module.

[0048] Further, in an embodiment, the shape of the hollow hole 320 is one of a circle, an ellipse, a rectangle, a trapezoid, a hexagon, an octagon, and a hexagonal star; preferably, the shape of the hollow hole 320 is a circle.

[0049] As shown in Figure 4 , when the shape of the hollow hole 320 is a circle, the aperture of the hollow hole 320 is greater than or equal to 0.7 mm and less than or equal to 0.8 mm; specifically, the aperture of the hollow hole 320 is preferably one of 0.7 mm or 0.8 mm.

[0050] It can be understood that the embodiment sets the shape of the hollow hole 320 to be an axisymmetric figure, and the shape of the hollow hole 320 is preferably a circle, so that the light emitted by the light emitting unit 20 in each direction can be uniformly emitted towards the light emitting direction through the reflecting layer 32, thereby making each part of the light emitting module 1 present a uniform brightness performance effect.

[0051] It should be noted that in an embodiment, as shown in Figure 5 , when n = 6, the shape of the hollow hole 320 is a hexagon; in an embodiment, as shown in Figure 6 , when n = 10, the shape of the hollow hole 320 is a hexagonal star; it can be understood that by setting the shape of the hollow hole 320 to be a regular n-sided polygon, where n is a positive integer greater than or equal to 5, the gap between the edge of the hollow hole 320 and the light emitting unit 20 is reduced, the effective reflection area of the reflecting layer 32 is increased, and the utilization of light is improved.

[0052] In the embodiment, the thickness of the reflective layer 32 is greater than or equal to the height of the light emitting unit 20; specifically, in a hollow hole 320 and the corresponding light emitting unit 20, the depth of the hollow hole 320 is greater than the height of the light emitting unit 20; it can be understood that the embodiment is provided in a hollow hole 320 and the corresponding light emitting unit 20, the depth of the hollow hole 320 is greater than the height of the light emitting unit 20, so that the light emitted laterally by the light emitting unit 20 can be effectively reflected to the light emitting surface of the light emitting module 1, thereby improving the light extraction efficiency.

[0053] In the embodiment, the material of the reflective layer 32 includes but is not limited to one or more of silver, magnesium, aluminum, platinum, and copper; further, the reflective layer 32 is preferably one of a silver reflective sheet or an ESR (Enhanced Specular Reflector) reflective sheet.

[0054] It should be noted that in the prior art, the conventional Mini-LED light emitting module 1 usually includes a reflective coating 31, and the reflective coating 31 is provided with a window 310, and a micro light emitting diode is located in the window 310, wherein the reflective coating 31 can effectively reflect the light emitted laterally by the micro light emitting diode to the light emitting surface of the light emitting module 1, thereby improving the light extraction efficiency; however, the reflective coating 31 usually uses a white oil material with fluidity, so that the height of the reflective coating 31 cannot be effectively controlled during actual production, thereby causing problems such as difficult production process, inability to effectively reflect the light emitted laterally by the micro light emitting diode to the light emitting surface of the light emitting module 1, and the like.

[0055] It can be understood that the embodiment uses a material that does not have fluidity by setting the material of the reflective layer 32 to include but not limited to one or more of silver, magnesium, aluminum, platinum, and copper, thereby maintaining the height of the reflective layer 32, so that the light emitted laterally by the light emitting unit 20 can be effectively reflected to the light emitting surface of the light emitting module 1, thereby improving the light extraction efficiency.

[0056] In the embodiment, the light emitting module 1 further includes an optical film group 40 located away from the substrate 10 on the side of the reflective layer 32, and the orthogonal projection of the optical film group 40 on the substrate 10 direction covers the orthogonal projection of the reflective layer 32 on the substrate 10 direction; wherein the side of the optical film group 40 close to the reflective layer 32 is parallel to the side of the reflective layer 32 close to the optical film group 40.

[0057] It should be noted that the optical film group 40 can include one or more of a prism sheet, a quantum dot film, a diffusion sheet, a reflective polarizing sheet, etc., so that the light emitting module 1 is adapted to diversified applications; for example, the prism sheet can change the exit angle of the light, thereby changing the viewable angle of the display device using the light emitting module 1; the quantum dot film can provide quantum dot light with higher monochromaticity, thereby widening the display color gamut of the display device using the light emitting module 1 and greatly improving the display brightness. The reflective polarizing sheet can improve the utilization rate of light while making the exiting light polarized, thereby omitting the lower polarizing sheet in the liquid crystal display panel.

[0058] It can be understood that please refer to the description of the first embodiment of the light emitting module Figure 1 As known in the prior art, since the light emitted by the micro light emitting diode is in all directions, part of the light is reflected back onto the light exit surface by the optical film group 40 located above the light emitting unit 20, thereby relatively low utilization rate of the light source; in the present embodiment, a reflective layer 32 is arranged on the substrate 10, the reflective layer 32 includes a plurality of hollow holes 320, one hollow hole 320 corresponds to one light emitting unit 20, and the light emitting unit 20 is located in the hollow hole 320, so that when the light emitted by the light emitting unit 20 is reflected back onto the light exit surface by the optical film group 40, the reflective layer 32 can efficiently reflect the light again, thereby improving the utilization rate of the light; at the same time, by arranging the side of the optical film group 40 close to the reflective layer 32 parallel to the side of the reflective layer 32 close to the optical film group 40, the uniform brightness performance of each part of the light emitting module 1 is achieved.

[0059] In another embodiment, please refer to Figure 7 The second structural diagram of the light emitting module provided by the present embodiment.

[0061] In the present embodiment, the light emitting module 1 further includes a reflective layer between the substrate 10 and the reflective layer 32, the reflective layer includes a plurality of openings, one opening corresponds to one hollow hole 320; wherein the aperture of the opening is larger than the aperture of the hollow hole 320.

[0062] Specifically, the light-reflecting layer is arranged around the outer periphery of the light-emitting unit 20, the material of the reflecting layer 32 includes but is not limited to white ink, the light-reflecting layer is arranged on the side away from the substrate 10, the reflecting layer 32 is arranged apart from the light-emitting unit 20 through the hollow holes 320, and the material of the reflecting layer 32 includes but is not limited to one or more of silver, magnesium, aluminum, platinum, and copper.

[0063] It can be understood that the reflection of the white ink can further improve the light-exiting efficiency, the reflecting layer 32 is arranged to include a plurality of hollow holes 320 exposing the light-emitting unit 20, so that the light-emitting unit 20 can smoothly exit light, the reflecting layer 32 is used for reflecting light, and thus the light emitted laterally by the light-emitting unit 20 or the light emitted by the light-emitting film piece group to the side of the substrate 10 can be re-reflected by the reflecting sheet to the light-exiting surface, thereby improving the utilization efficiency of the light source; and the reflecting layer 32 is arranged apart from the light-emitting unit 20, so as to avoid assembly errors and prevent the reflecting layer 32 from expanding and shrinking, thereby preventing damage to the light-emitting unit 20.

[0064] Specifically, please refer to Figure 1 , Figure 6 and Table 1; wherein Table 1 is the technical parameters and test results of the reflecting layer provided by the embodiment of the present application and the reflecting coating provided by the prior art.

[0068] It can be understood that the reflectivity R1 of the reflective layer 32 of embodiment one and the reflectivity R2 of the reflective layer 32 of embodiment two are both significantly improved compared with the reflectivity R3 of the reflective coating 31 of the prior art. It can be seen that the reflective layer 32 is arranged on the substrate 10, the reflective layer 32 includes a plurality of hollow holes 320, one hollow hole 320 corresponds to one light emitting unit 20, and the light emitting unit 20 is located in the hollow hole 320.
