[0040] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a display module according to a first embodiment provided by the present application, Figure 2 is Figure 1 is an imaging schematic diagram of the second light emitting device shown in FIG. 8.

[0041] The display module includes a substrate 11, a display panel 12, a second light emitting device 13 and a first lens 14. The display panel 12 is arranged on one side of the substrate 11. Specifically, the display panel 12 is arranged in parallel with the substrate 11; the display panel 12 and the substrate 11 can be arranged with a spacing or can be arranged in adhesion, which can be specifically described in the following content. The substrate 11 is provided with the second light emitting device 13 and the first lens 14. The positions of the second light emitting device 13 and the first lens 14 correspond to the orthographic projection gap of the adjacent two display panels 12 on the display panel 12. The material of the substrate 11 is transparent material; optionally, the material of the substrate 11 is glass. The surface of the substrate 11 close to the display panel 12 is a plane.

[0042] The display panel 12 comprises at least one first light emitting device 121. The first light emitting device 121 can be one or several of an LED, a mini LED, and a Micro-LED. The display panel 12 further comprises a substrate 122, and the first light emitting device 121 is disposed on the substrate 122; the first light emitting device 121 can be transferred to the substrate 122 by a transfer technology. In the embodiment, the width of the gap between two adjacent display panels 12 is substantially uniform along a direction parallel to the display panel 12.

[0043] The second light emitting device 13 is bonded to the surface of the substrate 11 close to the display panel 12. The light emitting direction of the second light emitting device 13 is the same as that of the first light emitting device 121; it is noted that the light emitting direction of the second light emitting device 13 is away from the substrate 11, and the light emitting directions of the first light emitting device 121 and the second light emitting device 13 are the same as the light emitting direction of the display panel 12. By correspondingly arranging the second light emitting device 13 in the gap between two adjacent display panels 12, and making the light emitting direction of the second light emitting device 13 the same as that of the first light emitting device 121, the light emitted by the second light emitting device 13 fills the gap between the two display panels 12. The first lens 14 is disposed on the side of the second light emitting device 13 away from the substrate 11. By arranging the first lens 14 on the side of the second light emitting device 13 away from the substrate 11, the first lens 14 is used to collect and focus the light emitted by the second light emitting device 13, and the display image formed by the light emitted by the second light emitting device 13 is presented on the side of the first lens 14 away from the second light emitting device 13, so as to realize the translation of the display image formed by the light emitted by the second light emitting device 13 in the direction away from the substrate 11, thereby reducing the visual existence of the gap between the two adjacent display panels 12, and reducing the height difference between the display image formed by the light emitted by the second light emitting device 13 and the display image formed by the light emitted by the first light emitting device 121, and improving the display effect of the display module formed by splicing the plurality of display panels 12 (such as shown in FIG. 1). Figure 2 The display image formed by the light emitted by the second light emitting device 13 is presented on the side of the first lens 14 away from the second light emitting device 13. By adjusting the parameters of the first lens 14 and the distance between the first lens 14 and the second light emitting device 13, the height of the display image formed by the light emitted by the second light emitting device 13 is adjusted, and the height difference between the display image formed by the light emitted by the second light emitting device 13 and the display image formed by the light emitted by the first light emitting device 121 is reduced, and even the display image formed by the light emitted by the second light emitting device 13 and the display image formed by the light emitted by the first light emitting device 121 can be located on the same plane.

[0044] The display panel 12 comprises at least one first light emitting device 121. The first light emitting device 121 can be one or several of an LED, a mini LED, and a Micro-LED. The display panel 12 further comprises a substrate 122, and the first light emitting device 121 is disposed on the substrate 122; the first light emitting device 121 can be transferred to the substrate 122 by a transfer technology. In the embodiment, the width of the gap between two adjacent display panels 12 is substantially uniform along a direction parallel to the display panel 12.

[0045] In the embodiment, the first lens 14 is a convex lens, the surface of the convex lens close to the second light emitting device 13 protrudes towards the second light emitting device 13, and the surface of the convex lens away from the second light emitting device 13 is concave towards the second light emitting device 13; that is, the first lens 14 is a convex lens in the form of concave-convex (or positive meniscus). It should be noted that the first lens 14 is not limited to the convex lens described above, and the first lens 14 can only reduce the visual existence of the gap between the adjacent two display panels 12.

[0046] In the embodiment, one first lens 14 is provided corresponding to a plurality of second light emitting devices 13. In other embodiments, one first lens 14 is provided corresponding to one second light emitting device 13. The number of corresponding arrangements between the second light emitting device 13 and the first lens 14 is specifically designed according to the requirements, which can reduce the visual existence of the gap between the adjacent two display panels 12 and improve the display effect.

[0047] Please refer to Figure 3 , Figure 3 is Figure 1 the first light emitting device and the second light emitting device in the structure of the schematic diagram of the orthographic projection on the substrate.

[0048] The gap between any adjacent two display panels 12 is provided with the second light emitting device 13 and the first lens 14, which can be several, to reduce the visual existence of the gap between any adjacent two display panels 12 in the display module.

[0049] The size of the second light emitting device 13 is the same as the size of the first light emitting device 121. For example, when the first light emitting device 121 is an LED, the second light emitting device 13 is also an LED of the same size; when the first light emitting device 121 is a mini LED, the second light emitting device 13 is also a mini LED of the same size; when the first light emitting device 121 is a Micro-LED, the second light emitting device 13 is also a Micro-LED of the same size.

[0050] The distribution density of the second light emitting device 13 is the same as that of the first light emitting device 121. Specifically, the first light emitting devices 121 on each display panel 12 are arranged in an array, and arranged in multiple rows and multiple columns. The second light emitting devices 13 in the gap between the adjacent two display panels 12 are arranged in an array. The orthographic projection of the second light emitting devices 13 in the same row on the substrate 11 is arranged in alignment with the orthographic projection of the first light emitting devices 121 in the same row on the substrate 11. The distance between the orthographic projections of the adjacent first light emitting device 121 and second light emitting device 13 on the substrate 11 is equal to the distance between the adjacent two columns of first light emitting devices 121; that is, the distance between the orthographic projections of the second light emitting device 13 and the first light emitting device 121 adjacent to the second light emitting device 13 on the substrate 11 is equal to the distance between the adjacent two columns of first light emitting devices 121. And / or, the distance between the adjacent two columns of second light emitting devices 13 is equal to the distance between the adjacent two columns of first light emitting devices 121. It can be understood that a row of second light emitting devices 13 can have only one second light emitting device 13, or can have multiple second light emitting devices 13, which is determined according to the gap width between the adjacent two display panels 12 and the size of the first light emitting device 121.

[0051] By setting the size of the second light emitting device 13 to be the same as that of the first light emitting device 121, the distribution density of the second light emitting device 13 is the same as that of the first light emitting device 121, the pixel density of the entire display module is kept consistent, and the display module has good display effect on the basis of reducing the visual existence of the gap between the two display panels 12.

[0052] Continuing to refer to Figure 1 The orthographic projection of the second light emitting device 13 on the display panel 12 completely covers the gap between the adjacent two display panels 12, so that the light emitted by the second light emitting device 13 can fill the gap between the adjacent two display panels 12, reducing the visual existence of the gap between the two display panels 12.

[0053] The width of the second light emitting device 13 arranged along the first direction X is denoted as L1, and the width of the gap between the adjacent two display panels 12 along the first direction X is denoted as L2, L1 can be greater than or equal to L2; the length of the second light emitting device 13 arranged along the second direction Y can be greater than or equal to the length of the gap between the adjacent two display panels 12 along the second direction Y, wherein the second direction Y is perpendicular to the first direction X, so that the light emitted by the second light emitting device 13 can fill the gap between the adjacent two display panels 12. In an example, Figure 1 L1 is greater than L2. It should be noted that Figure 3The first direction X and the second direction Y are shown in FIG. 1, and the first direction X and the second direction Y respectively refer to two arrangement directions of the first light emitting device 121 and / or the second light emitting device 13. Figure 1 The second direction Y shown in FIG. 1 is perpendicular to Figure 1 the direction of the cross section shown in FIG. 1.

[0054] The size of the orthographic projection of the plurality of first lenses 14 on the substrate 11 along the first direction X is denoted as L3, and L3 can be greater than or equal to L1; the size of the orthographic projection of the plurality of first lenses 14 on the substrate 11 along the second direction Y is greater than or equal to the length of the plurality of second light emitting devices 13 arranged along the second direction Y, so as to adjust the height of the display image formed by the light emitted by the second light emitting device 13. For example, one first lens 14 is arranged between two adjacent display panels 12. For example, two first lenses 14 are arranged between two adjacent display panels 12.

[0055] Please refer to Figures 4a to 4b , Figure 4a is Figure 1 the structure diagram of an embodiment of the bracket shown in FIG. 2, Figure 4b is Figure 4a the top view structure diagram of the bracket shown in FIG. 2.

The bracket 16 has a mounting portion 161, and the first lens 14 is fixed to the mounting portion 161. In this embodiment, the bracket 16 has a ring structure, and the inner surface of the ring structure is provided with a first slot as the mounting portion 161; the first slot can be a groove on the inner surface of the ring structure. Alternatively, the inner surface of the ring structure is provided with a plurality of spaced first slots. Alternatively, the inner surface of the ring structure is provided with one first slot, and the first slot is annular. The end of the first lens 14 is arranged in the first slot to fix the first lens 14. The second light emitting device 13 is located in the ring structure of the bracket 16.

[0057] Please refer to Figures 5a to 6 , Figure 5a is Figure 1 the structure diagram of another embodiment of the bracket shown in FIG. 3, Figure 5b is Figure 5a the top view structure diagram of the bracket shown in FIG. 3, Figure 6 is Figure 5a the structure diagram between the bracket, the second light emitting device and the first lens shown in FIG. 3.

[0058] In this embodiment, the support 16 comprises a ring-shaped body 163 and a protrusion 162 arranged on the inner surface of the ring-shaped body 163. The edge of the first lens 14 is overlapped with the surface of the protrusion 162 away from the substrate 11, so as to fix the first lens 14. Optionally, the ring-shaped body 163 and the protrusion 162 are integrally formed. Optionally, the inner surface of the ring-shaped body 163 is provided with a plurality of spaced protrusions 162. Optionally, the inner surface of the ring-shaped body 163 is provided with one protrusion 162, and the protrusion 162 is in a ring-shaped structure. Optionally, the surface of the protrusion 162 away from the substrate 11 is arranged in an arc surface, which is matched with the surface of the first lens 14 close to the substrate 11, so that the first lens 14 is placed on the arc surface, and the first lens 14 is fixed. Optionally, the plane of the protrusion 162 close to the substrate 11 is in the same plane as the surface of the ring-shaped body 163 close to the substrate 11.

[0059] It should be noted that the specific arrangement of the support 16 is not limited to the structure provided in the above embodiment, and the first lens 14 can be fixed. The display panel 12 is arranged in parallel and spaced apart from the substrate 11, and the display panel 12 is fixed to the substrate 11 by the support column 17. Optionally, the support 16 is located between the substrate 11 and the display panel 12, and the end surface of the support 16 away from the substrate 11 abuts against the surface of the display panel 12 close to the substrate 11. Optionally, the support 16 is located between two adjacent display panels 12, and the end surface of the support 16 away from the substrate 11 is not higher than the surface of the display panel 12 away from the substrate 11.

[0060] Please refer to Figure 7 , Figure 7 which is a structural schematic diagram of a second embodiment of the display module provided in the present application.

[0061] The second embodiment of the display module and the first embodiment of the display module have basically the same structure, and the difference lies in that the display panel 12 is arranged in adhesion with the substrate 11, and the same parts will not be described again.

[0062] In this embodiment, the surface of the substrate 11 close to the display panel 12 is a plane, and the substrate 122 of the display panel 12 is adhered to the substrate 11. The thickness of the substrate 122 of the display panel 12 in the second embodiment of the display module is set to be greater than the thickness of the substrate 122 of the display panel 12 in the first embodiment of the display module, so that the second light emitting device 13 and the first lens 14 can be arranged in the gap between two adjacent display panels 12.

[0063] The support 16 can be in the structure as shown in Figure 4a , or in the structure as shown in Figure 5a . The support 16 is located between two adjacent display panels 12, and the end surface of the support 16 away from the substrate 11 is not higher than the surface of the display panel 12 away from the substrate 11. The side surface of the support 16 can abut against the side surface of the display panel 12.

[0064] See also Figure 8 and Figure 9 , Figure 8 is a structural diagram of the third embodiment of the display module provided by this application, Figure 9 yes Figure 8 Schematic diagram of imaging of the second light-emitting device shown.

[0065] The structure of the display module in the third embodiment is substantially the same as that of the display module in the first embodiment, except that the display module further includes a second lens 15 . The same parts will not be described again.

[0066] In this embodiment, the second lens 15 is provided on the side of the first lens 14 away from the second light-emitting device 13. The second lens 15 is used to refract the light collected by the first lens 14 and focus the light into an image. The display image formed by the light emitted by the second light-emitting device 13 is presented on the side of the second lens 15 away from the second light-emitting device 13, so that the display image formed by the light emitted by the second light-emitting device 13 is further translated in a direction away from the substrate 11, so that the display image formed by the light emitted by the second light-emitting device 13 and the display image formed by the light emitted by the first light-emitting device 121 are located in the same plane (e.g., Figure 9 As shown), the height difference between the display image formed by the light emitted by the second light-emitting device 13 and the display image formed by the light emitted by the first light-emitting device 121 is eliminated, and the visual presence of the gap between the two adjacent display panels 12 is further reduced. The display module formed by splicing multiple display panels 12 has a better display effect.

[0067] It should be noted that the second lens 15 is an optional structure. If the display image formed by the light emitted by the second light-emitting device 13 and the display image formed by the light emitted by the first light-emitting device 121 can be located in the same plane by adjusting the parameters of the first lens 14 and the distance between the first lens 14 and the second light-emitting device 13, then the second lens 15 is not required. If adjusting the parameters of the first lens 14 and the distance between the first lens 14 and the second light-emitting device 13 is not sufficient to ensure that the display image formed by the light emitted by the second light-emitting device 13 and the display image formed by the light emitted by the first light-emitting device 121 are located in the same plane, then the second lens 15 is provided on the side of the first lens 14 away from the second light-emitting device 13. The second lens 15 cooperates with the first lens 14 to ensure that the display image formed by the light emitted by the second light-emitting device 13 and the display image formed by the light emitted by the first light-emitting device 121 are located in the same plane.

[0068] The second lens 15 is a convex lens. The surface of the convex lens near the second light-emitting device 13 protrudes toward the second light-emitting device 13, and the surface of the convex lens away from the second light-emitting device 13 protrudes away from the second light-emitting device 13; that is, the second lens 15 is a biconvex convex lens. It should be noted that the second lens 15 is not limited to the convex lens described above. The second lens 15 can cooperate with the first lens 14 to reduce the visual presence of the gap between two adjacent display panels 12 and the height difference between the display image formed by the light emitted by the second light-emitting device 13 and the display image formed by the light emitted by the first light-emitting device 121.

The second slot 164 can be specifically a groove on the inner surface of the annular structure.

[0072] In one embodiment, if Figure 11 As shown, the structure of the bracket 16 is similar to Figure 5a The structures are basically the same, except that a second slot 164 is provided on the inner surface of the annular body 163 , and the second slot 164 is located on the side of the protrusion 162 away from the substrate 11 .
