Refer to Figures 1 to 5 As shown, the embodiment of the present invention provides a display module 10. The display module 10 includes at least two display panels 100; the display panel 100 includes: an array substrate 1000; a light-emitting element 2000, and the light-emitting element 2000 is located on one side of the array substrate 1000; the light-emitting element 2000 includes a first state and a second state, and the brightness of the light-emitting element 2000 in the first state is greater than the brightness of the light-emitting element 2000 in the second state; a packaging layer 3000, and the packaging layer 3000 is located on the side of the light-emitting element 2000 away from the array substrate 1000; the display panel 100 includes a first display panel 101 and a second display panel 102, and the first display panel 101 and the second display panel 102 are arranged along the first direction X1; the display module 10 further includes a light adjustment structure 4000, and the light adjustment structure 4000 is located on the side of the packaging layer 3000 close to the array substrate 1000; the light adjustment structure 4000 is located between the first display panel 101 and the second display panel 102, and the light adjustment structure 4000 overlaps at least a part of the first display panel 101 and at least a part of the second display panel 102 respectively; the light adjustment structure 4000 extends along the second direction X2; the display module 10 further includes an adjustment wire 5000, and the adjustment wire 5000 extends along the thickness direction of the array substrate 1000, and the adjustment wire 5000 is connected to the light adjustment structure 4000; in the first state, the refractive index of the light adjustment structure 4000 is n1; in the second state, the refractive index of the light adjustment structure 4000 is n2, satisfying: n1 > n2; wherein, the first direction X1 and the second direction X2 intersect and are parallel to the plane where the array substrate 1000 is located.

[0044] Among them, the display module 10 includes a display panel 100, and the display panel 100 has a display function, thereby realizing the display effect of the display module 10. Further, the display module 10 includes a plurality of display panels 100, and the plurality of display panels 100 can be combined and spliced, thereby realizing the large-size display effect of the display module 10 and ensuring a better overall display effect of the display module 10. Exemplarily, Figure 1 In

[0045] Further, referring to Figures 1 to 3 as shown, the display panel 100 includes an array substrate 1000 and a light-emitting element 2000 disposed on one side of the array substrate 1000. By driving the light-emitting element 2000 to emit light for display, the display function of the display panel 100 is realized, and further the display function of the display module 10 is realized. Among them, the light-emitting element 2000 includes a first state and a second state. In the first state, the light-emitting brightness of the light-emitting element 2000 is greater than that in the second state. Comparing the first state and the second state, the first state can be understood as the display panel 100 being in a bright state, and the second state can be understood as the display panel 100 being in a dark state. For the specific brightness values corresponding to the light-emitting element 2000 in the first state and the second state, the embodiments of the present invention do not limit this. Further, the display panel 100 further includes a packaging layer 3000. The packaging layer 3000 is used to package and protect the display panel 100, and at the same time can also ensure the flatness of the overall display panel 100.

[0046] Specifically, referring to Figure 2 and Figure 3 as shown, the display panel 100 includes a first display panel 101 and a second display panel 102, where the first display panel 101 and the second display panel 102 are arranged along the first direction X1. The display module 10 includes a light adjustment structure 4000 extending along the second direction X2. The light adjustment structure 4000 is located between the first display panel 101 and the second display panel 102, that is, the light adjustment structure 4000 is located at the seam between the first display panel 101 and the second display panel 102. Further, referring to Figure 2 and Figure 3 as shown, the light adjustment structure 4000 overlaps at least part of the first display panel 101 and at least part of the second display panel 102, that is, the light adjustment structure 4000 is not only located at the seam of the adjacent display panels 100, but also overlaps with the edges of the adjacent display panels 100.

[0047] Further, the light adjustment structure 4000 is located on the side of the packaging layer 3000 close to the array substrate 1000. Referring to Figure 3 as shown, the area where the light adjustment structure 4000 overlaps with the display panel 100 is also covered by the subsequently prepared packaging layer 3000. On the one hand, the packaging layer 3000 can ensure the structural stability of the light adjustment structure 4000 and the overall structural stability of the display module 10. On the other hand, it can also ensure the flatness of the overall display panel 100 and the overall flatness of the display module 10. In this way, the display panel 100 will not have protrusions due to the addition of the light adjustment structure 4000.

[0048] Further, referring toFigures 1 to 3 As shown, the display module 10 further includes an adjustment wire 5000. The adjustment wire 5000 is connected to the light adjustment structure 4000. The adjustment wire 5000 can transmit relevant signals such as different temperatures or different currents to the light adjustment structure 4000 according to the light-emitting element 2000 being in different brightness states, such as the first state or the second state. The light adjustment structure 4000 adjusts the refractive index accordingly, so as to ensure the overall display effect of the display module 10. Among them, the array substrate 1000 includes a metal layer and an insulating layer arranged in a stacked manner. Among them, the adjustment wire 5000 can be electrically connected to the corresponding metal layer by drilling down from the light adjustment structure 4000 to the array substrate 1000, so as to realize the transmission of relevant signals. For the specific film layer setting method in the array substrate 1000, it can be adaptively increased or decreased according to actual needs, and the embodiments of the present invention do not specifically limit this.

[0049] Exemplarily, when the light-emitting element 2000 realizes different luminous brightnesses, the driving currents corresponding to the light-emitting element 2000 are different. The relevant current signals can be transmitted to the light adjustment structure 4000 through the adjustment wire 5000. The light adjustment structure 4000 adjusts the refractive index according to different electrical signals (such as current or voltage, etc.). The material of the light adjustment structure 4000 can be an electro-optic crystal. Or, when the light-emitting element 2000 realizes different luminous brightnesses, the heat generated by the light-emitting element 2000 due to light emission is different. Different heats can be transmitted to the light adjustment structure 4000 through the adjustment wire 5000 or different heats can be transmitted to the light adjustment structure 4000 through the encapsulation layer 3000, etc. The light adjustment structure 4000 adjusts the refractive index according to different temperature values. Optionally, some particles whose refractive index changes with temperature can be doped in the light adjustment structure 4000.

[0050] Specifically, in the area where the light adjustment structure 4000 is arranged in the display module 10, it was originally the seam between two display panels 100, and the seam is an air gap. If there is no light adjustment structure 4000, due to the difference in refractive index between the air gap and the film layer structure at the seam, part of the light emitted by the light-emitting element 2000 near the seam of the display panel 100 will undergo total reflection, resulting in a decrease in the brightness at the seam and affecting the overall display uniformity of the display module 10. Refer to Figures 2 to 4As shown, by providing a light adjustment structure 4000 at the seam between two adjacent display panels 100, and by adjusting the refractive index of the light adjustment structure 4000. Further, the shape of the provided light adjustment structure 4000 can be equivalent to a convex lens, which can better achieve light adjustment. Thus, the light emitted by the light-emitting elements 2000 near the seam can pass through the seam and be refracted, thereby ensuring the overall display uniformity of the display module 10 and improving the overall display effect of the display module.

[0051] Further, for the display module 10 provided in the embodiment of the present invention, the refractive index of the light adjustment structure 4000 can also be more finely adjusted according to the different brightness of the light-emitting elements 2000, so as to ensure that the display effect of the display module 10 can be guaranteed under different display requirements. Specifically, in the first state, the refractive index of the light adjustment structure 4000 is n1; in the second state, the refractive index of the light adjustment structure 4000 is n2, where: n1 > n2. Since the greater the brightness of the light-emitting element 2000, the greater the refractive index of the adjusted light adjustment structure 4000, it can ensure that more light passes through the seam, and the display at the seam and the display panel 100 can be made balanced. Optionally, in the second state, the light-emitting element 2000 may not emit light or emit light with a lower brightness. It should be noted that Figure 4 and Figure 5 for comparison and reference, Figure 4 the brightness of the light-emitting element 2000 in Figure 5 is greater than the brightness of the light-emitting element 2000 in Figure 4 and the refractive index of the light adjustment structure 4000 in Figure 5 is greater than the refractive index of the light adjustment structure 4000 in Figure 4 and Figure 5 wherein the arrow can be understood as adjusting the light transmission path transmitted to the light adjustment structure 4000.

[0052] Optionally, as shown in Figure 2 the display panel 100 further includes a substrate 1001 and a cover plate 1002. The substrate 1001 is located on the side of the array substrate 1000 away from the encapsulation layer 3000, and the cover plate 1002 is located on the side of the encapsulation layer 3000 away from the array substrate 1000. The film layer structure provided in the display panel 100 can also be adaptively adjusted according to actual needs, and the embodiment of the present invention does not specifically limit this.

[0053] Optionally, for the light-emitting elements 2000 in the display panel 100, they can be micro light-emitting elements or mini light-emitting elements, etc., and the embodiment of the present invention does not specifically limit this.

[0054] In summary, the embodiment of the present invention provides a display module. The display module is provided with a light adjustment structure. The light adjustment structure is arranged at the seam between the first display panel and the second display panel and overlaps with the first display panel and the second display panel. Further, an adjustment wire is connected to the light adjustment structure, and the refractive index of the light adjustment structure is adjusted by combining different states of the light-emitting elements. Specifically, the refractive index of the light adjustment structure in the first state is greater than that in the second state. Therefore, the light adjustment structure can adjust the refractive index in combination with different display brightnesses of the display panel, so as to avoid large display differences at the seam between different display panels, thereby improving the overall display uniformity of the display module and further improving the display effect of the display module.

[0055] Continuing to refer to Figures 1 to 5 As shown, the display panel 100 further includes a light-blocking module 6000. The light-blocking module 6000 is located between two adjacent light-emitting elements 2000. The second state further includes a first sub-state, in which the light-emitting element 2000 does not emit light. The refractive index of the encapsulation layer 3000 is na. In the first sub-state, the refractive index of the light adjustment structure 4000 is n3. It satisfies: |n3 - na| / na ≤ 20%.

[0056] Further, referring to Figures 3 to 5 As shown, the display panel 100 further includes a light-blocking module 6000. The light-blocking module 6000 is located between two adjacent light-emitting elements 2000, and the light-blocking module 6000 can block the transmission of light. Setting the light-blocking module 6000 can avoid light crosstalk between different light-emitting elements 2000, ensure the display effect of the display panel 100, and ensure the overall display effect of the display module 10.

[0057] Among them, the second state further includes a first sub-state, which can be understood as that the light-emitting element 2000 does not emit light for display at all. Specifically, when the light-emitting element 2000 of the display module 10 does not emit light (i.e., in the dark state), if there is no light adjustment structure 4000, some ambient light will be emitted at the seam because it is an air gap and there is no film layer to block it. However, due to the existence of the light-blocking structure 6000 in the display panel 100, some ambient light can be blocked, resulting in a situation where the display module 10 is brighter at the seam and the display panel 100 is darker in this state, affecting the overall display uniformity of the display module 10. Therefore, by setting the light adjustment structure 4000 and adjusting the refractive index of the light adjustment structure 4000, when the light-emitting element 2000 does not emit light for display, the light transmitted from the seam can be diverged by the light adjustment structure 4000, avoiding the concentrated emission of light at the seam, thereby balancing the display effect of the display module 10 in the dark state and ensuring the overall display effect of the display module 10.

[0058] Further, the refractive index of the encapsulation layer 3000 is na. In the first sub-state, the refractive index of the light adjustment structure 4000 is adjusted to n3, satisfying |n3 - na| / na ≤ 20%, that is, when the light-emitting element 2000 does not emit light for display, the refractive index of the light adjustment structure 4000 is the same as or close to that of the encapsulation layer 3000. Therefore, when the light-emitting element 2000 emits light for display, the refractive index of the light adjustment structure 4000 can be adjusted to be greater than that of the encapsulation layer 3000. Further, the shape of the provided light adjustment structure 4000 is equivalent to a convex lens, which can better adjust the light. This can also be understood as that when the display module 10 is in the dark state, the refractive index of the light adjustment structure 4000 is adjusted to that of the encapsulation layer 3000, and the ambient light can be refracted by the light adjustment structure 400, thereby reducing the transmitted brightness of the ambient light at the seam; when the display module 10 is in the bright state, the refractive index of the light adjustment structure 4000 is adjusted to be greater than that of the encapsulation layer 3000, and the light transmitted from the light-emitting element 2000 to the seam can be emitted at the seam, thereby ensuring the overall display effect of the display module 10.

[0059] Figure 6 It is a schematic structural diagram of the second display module provided by the embodiment of the present invention. Figure 7 It is a schematic structural diagram of the third display module provided by the embodiment of the present invention. Figure 8 is Figure 2 the first cross-sectional schematic diagram along the section line C-C' in Figure 1 、 Figure 2 、 Figures 6 to 8 As shown, the array substrate 1000 includes a driving unit 1100. The driving unit 1100 includes a pixel driving circuit 1110 and a scan driving circuit 1120. The scan driving circuit 1120 is electrically connected to the pixel driving circuit 1110, and the pixel driving circuit 1110 is electrically connected to the light-emitting element 2000; the display panel 100 includes a first area and a second area. The second area is located on one side of the first area. The light-emitting element 2000 and the pixel driving circuit 1110 are located in the first area; the scan driving circuit 1120 is located in the second area; the adjustment wire 5000 includes a voltage adjustment trace 5100. The voltage adjustment trace 5100 includes a first voltage adjustment trace 5110 and a second voltage adjustment trace 5120. The first voltage adjustment trace 5110 is electrically connected to the pixel driving circuit 1110 in the first display panel 101, and the second voltage adjustment trace 5120 is connected to the pixel driving circuit 1110 in the second display panel 102.

[0060] Specifically, referring to Figure 6 and Figure 7As shown, the display panel 100 includes a driving unit 1100, which is disposed in the array substrate 1000. The driving unit 1100 includes a pixel driving circuit 1110 and a scanning driving circuit 1120. The scanning driving circuit 1120 is electrically connected to the pixel driving circuit 1110. The scanning driving circuit 1120 provides a light-emitting signal, a scanning signal, etc. to the pixel driving circuit 1110. The pixel driving circuit 1110 is electrically connected to the light-emitting element 2000. The pixel driving circuit 1110 generates a driving current by combining the acquired signals and then drives the light-emitting element 2000 to emit light for display, thereby realizing the display function of the display panel 100 and the display function of the display module 10. It should be noted that Figure 6 and Figure 7 the specific connection traces are not shown.

[0061] Furthermore, the display panel 100 includes a first region and a second region. The first region can be understood as the setting region corresponding to the light-emitting element 2000 and the pixel driving circuit 1110, and the second region can be understood as the setting region corresponding to the scanning driving circuit 1120. Optionally, referring to Figure 6 and Figure 7 as shown, a plurality of pixel driving circuits 1110 arranged along the first direction X1 are row pixel driving circuits. The scanning driving circuit 1120 can provide electrical signals to the row pixel driving circuits arranged along the first direction X1. Therefore, a plurality of scanning driving circuits 1120 can be arranged between different row pixel driving circuits, such as Figure 6 shown; or a plurality of scanning driving circuits 1120 are arranged at the edge of the display panel 100, such as Figure 7 shown. Since there are various ways to arrange the scanning driving circuit 1120, the specific division of the first region and the second region is also diverse.

[0062] Furthermore, referring to Figure 8 as shown, the pixel driving circuit 1110 includes at least one transistor 1111. The transistor 1111 is electrically connected to the light-emitting element 2000 and provides a driving current for the light-emitting element 300, thereby ensuring the normal display of the display panel 100. Figure 8 The pixel driving circuit 1110 is not specifically shown in . Only one transistor 1111 is used as an example for illustration. Furthermore, the array substrate 1000 includes a plurality of stacked film layers, such as a buffer layer, a gate insulating layer, an interlayer insulating layer, a planarization layer, etc. The specific types and quantities of the film layers in the array substrate 1000 can be adjusted adaptively according to different requirements, and are not specifically limited in the embodiments of the present invention. Furthermore, Figure 8The transistor 1111 shown in the middle pixel driving circuit 1110 includes: an active layer 1111a, a gate 1111b, a drain 1111c, and a source 1111d. For the specific setting of the transistor 1111, it can also be adjusted adaptively according to requirements, and the embodiments of the present invention do not specifically limit this. Further, the display panel 100 also includes a connection structure 1200, and the light-emitting element 2000 can be electrically connected to the pixel driving circuit 1110 through the connection structure 1200.

[0063] Specifically, referring to Figure 8 As shown, the adjustment wire 5000 includes a voltage adjustment trace 5100. The voltage adjustment trace 5100 includes a first voltage adjustment trace 5110 and a second voltage adjustment trace 5120. Among them, the first voltage adjustment trace 5110 is electrically connected to the pixel driving circuit 1110 in the first display panel 101, and the second voltage adjustment trace 5120 is electrically connected to the pixel driving circuit 1110 in the second display panel 102. Among them, the brightness of the light-emitting element 2000 is related to the magnitude of the current transmitted to the light-emitting element 2000. Therefore, the light adjustment structure 4000 can be electrically connected to the pixel driving circuit 1110, and combined with the electrical signal provided to the light-emitting element 2000, etc., to realize the refractive index adjustment of the light adjustment structure 400. Optionally, the display module 10 further includes a driving chip (not specifically shown in the figure). The driving chip transmits relevant electrical signals to the scanning driving circuit 1120, etc., and the light adjustment structure 4000 can also be electrically connected to the driving chip.

[0064] Generally speaking, the light adjustment structure 4000 can adjust the refractive index in combination with the light-emitting conditions of the light-emitting elements 2000 in the first display panel 101 and the light-emitting conditions of the light-emitting elements 2000 in the second display panel 102, so as to ensure the overall display effect of the display module 10.

[0065] Further, the refractive index of the encapsulation layer 3000 is na; in the first state, the light adjustment structure 4000 receives a first voltage V1 through the voltage adjustment trace 5100, and the refractive index of the light adjustment structure 4000 is n11; in the second state, the light adjustment structure 4000 receives a second voltage V2 through the voltage adjustment trace 5100, and the refractive index of the light adjustment structure 4000 is n12; where n11 > na ≥ n12, |n11 - na| > |n12 - na|.

[0066] Among them, the refractive index of the encapsulation layer 3000 is na, and the refractive index of the light adjustment structure 4000 changes according to the voltage value provided by the voltage adjustment structure 5100, so as to satisfy that the refractive index of the light adjustment structure 4000 in the first state is greater than that in the second state. Specifically, in the first state, the light adjustment structure 4000 receives the first voltage V1 through the voltage adjustment trace 5100; in the second state, the light adjustment structure 4000 receives the second voltage V2 through the voltage adjustment trace 5100. When the light adjustment structure 4000 obtains the first voltage V1, the corresponding refractive index is n11, and when the light adjustment structure 4000 obtains the second voltage V2, the corresponding refractive index is n12. It satisfies: n11 > na, na ≥ n12. That is, when the light-emitting element 2000 is in the first state, the emission brightness is relatively high. In order to avoid a lower brightness at the seam between the first display panel 101 and the second display panel 102, the refractive index of the light adjustment structure 4000 is adjusted to be greater than the refractive index of the encapsulation layer 3000; when the light-emitting element 2000 is in the second state, the emission brightness is relatively low. In order to avoid a higher brightness at the seam between the first display panel 101 and the second display panel 102, the refractive index of the light adjustment structure 4000 is adjusted to be equal to or less than the refractive index of the encapsulation layer 3000.

[0067] Furthermore, |n11 - na| > |n12 - na|, that is to say, the difference between the refractive index of the light adjustment structure 4000 and the refractive index of the encapsulation layer 3000 in the first state is greater than the difference between the refractive index of the light adjustment structure 4000 and the refractive index of the encapsulation layer 3000 in the second state. Combining the voltage value obtained by the light adjustment structure 4000, a more detailed division of the adjustment of its refractive index can be carried out, which can ensure that the adjustment of the refractive index of the light adjustment structure 4000 is more regular, reduce the implementation difficulty, and ensure the overall display effect of the display module 10.

[0068] Optionally, (V1 - V2)*(n11 - n12) > 0; or (V1 - V2)*(n11 - n12) < 0.

[0069] Specifically, for the relationship between the refractive index and the voltage value: |n11 - na| > |n12 - na|, it can be (V1 - V2)*(n11 - n12) > 0; or (V1 - V2)*(n11 - n12) < 0. Among them, (V1 - V2)*(n11 - n12) > 0 can be understood as that the voltage values input to the light ray adjustment structure 4000 can all be positive values, that is, both the first voltage V1 and the second voltage V2 are positive numbers (and V1 > V2), or the first voltage V1 is a positive number and the second voltage is a negative number. Among them, (V1 - V2)*(n11 - n12) < 0 can be understood as that the voltage values input to the light ray adjustment structure 4000 can all be negative values, that is, both the first voltage V1 and the second voltage V2 are negative numbers (and V1 > V2). For the specific voltage input situation, it can be adaptively adjusted according to actual needs, and the embodiments of the present invention do not make specific limitations, reflecting the diversity of realizing the refractive index adjustment of the light ray adjustment structure 4000.

[0070] Continue to refer to Figure 8 As shown, the display panel 100 includes a connection trace 7000, and the voltage adjustment trace 5100 is electrically connected to the pixel driving circuit 1110 through the connection trace 700; the pixel driving circuit 1110 includes a plurality of metal trace layers, and the connection trace 7000 is disposed on the same layer as at least one of the metal trace layers.

[0071] Furthermore, referring to Figure 8 As shown, the display panel 100 includes a connection trace 7000, and the connection trace 7000 is disposed on the same layer as at least one of the metal trace layers in the pixel driving circuit 1110. The metal trace layer can be understood as the metal film layer where the gate 1111b, the drain 1111c, the source 1111d, etc. are located. Optionally, Figure 8 the connection trace 7000 in is disposed on the same layer as the source 1111d. It should be noted that Figure 8 is a cross-sectional view, and not all the connection situations of the traces are shown, only the situation of being disposed on the same layer is shown. By disposing the connection trace 7000 on the same layer as at least one of the metal trace layers, the overall film layer thickness of the display module 10 can be effectively reduced, and the traces disposed on the same layer can also be prepared synchronously, which is beneficial to reducing the process preparation cost of the display panel 10.

[0072] Refer to Figure 2 and Figure 8 As shown, the orthographic projection of the connection trace 7000 on the array substrate 1000 and the orthographic projection of the light ray adjustment structure 4000 on the array substrate 1000 at least partially overlap.

[0073] Specifically, refer to Figure 2 and Figure 8As shown, the orthographic projection of the light adjustment structure 4000 onto the array substrate 1000 covers the orthographic projection of the connection traces 7000 onto the array substrate 1000. In this way, by using the method of spatial multiplexing, the occupied space of the traces in the display panel 100 can be reduced. The larger the saved space, the more light-emitting elements 2000 can be arranged, etc., improving the display effect of the display panel 100; or the saved space can provide a larger routing space for the remaining traces, reducing the interference between signals of different traces, thereby ensuring the overall stability of the display module 10.

[0074] Figure 9 is Figure 2 the second cross-sectional schematic diagram along the section line C-C' in Figure 10 and is an enlarged schematic diagram of a light adjustment structure provided by an embodiment of the present invention. Refer to Figure 2 、 Figure 9 and Figure 10 As shown, the light adjustment structure 4000 includes temperature-sensitive particles 4100; the adjustment wire 5000 includes a temperature adjustment trace 5200, and the temperature adjustment trace 5200 includes a first temperature adjustment trace 5210 and a second temperature adjustment trace 5220. The first temperature adjustment trace 5210 is used to obtain the heat generated by the light-emitting elements 2000 in the first display panel 101, and the second temperature adjustment trace is used to obtain the heat generated by the light-emitting elements 2000 in the second display panel 102; in the first state, the temperature obtained by the light adjustment structure 4000 through the temperature adjustment trace 5200 is T1, and the refractive index of the light adjustment structure 4000 is n13; in the second state, the temperature obtained by the light adjustment structure 4000 through the temperature adjustment trace 5200 is T2, and the refractive index of the light adjustment structure 4000 is n14, satisfying: T1 > T2, n13 > n14.

[0075] Among them, refer to Figure 8 and Figure 9 As shown, the light adjustment structure 4000 includes temperature-sensitive particles 4100. The temperature-sensitive particles 4100 can adjust the refractive index according to the ambient temperature, thereby realizing the change of the refractive index of the light adjustment structure 4000 in different temperature environments. Specifically, when the light-emitting elements 2000 are at different brightness levels, different amounts of heat are transferred to the film layer (such as the encapsulation layer 3000). The refractive index of the light adjustment structure 4000 can be adaptively adjusted according to the temperature difference, so as to satisfy that the refractive index of the light adjustment structure 4000 when the light-emitting elements 2000 are in the first state is greater than the refractive index when the light-emitting elements 2000 are in the second state.

[0076] Specifically, refer to Figure 8As shown in the figure, the adjustment wire 5000 includes a temperature adjustment wire 5200, and the temperature adjustment wire 5200 includes a first temperature adjustment wire 5210 and a second temperature adjustment wire 5220. The first temperature adjustment wire 5210 is used to obtain the heat generated by the light-emitting element 2000 in the first display panel 101, and the second temperature adjustment wire 5220 is used to obtain the heat generated by the light-emitting element 2000 in the second display panel 102. Optionally, the first temperature adjustment wire 5210 can be electrically connected to the corresponding pixel driving circuit 1110 in the first display panel 101, and the heat is transmitted to the light adjustment structure 4000 through the first temperature adjustment wire 5210; the second temperature adjustment wire 5220 can be electrically connected to the corresponding pixel driving circuit 1110 in the second display panel 102, and the heat is transmitted to the light adjustment structure 4000 through the second temperature adjustment wire 5220. Optionally, the heat generated by the light-emitting element 2000 can also be transmitted to the light adjustment structure 4000 through film layer structures such as the encapsulation layer 3000.

[0077] Specifically, in the first state, the temperature obtained by the light adjustment structure 4000 through the temperature adjustment wire 5200 is T1; in the second state, the temperature obtained by the light adjustment structure 4000 through the temperature adjustment wire 5200 is T2. When the temperature of the light adjustment structure 4000 is T1, the corresponding refractive index is n13, and when the temperature of the light adjustment structure 4000 is T2, the corresponding refractive index is n14. The following is satisfied: T1 > T2; n13 > n14. That is, when the light-emitting element 2000 is in the first state, the light-emitting brightness is high. In order to avoid a low brightness at the seam between the first display panel 101 and the second display panel 102, the refractive index of the light adjustment structure 4000 is adjusted to be large; when the light-emitting element 2000 is in the second state, the light-emitting brightness is low. In order to avoid a high brightness at the seam between the first display panel 101 and the second display panel 102, the refractive index of the light adjustment structure 4000 is adjusted to be small. This reflects the diversity of the refractive index adjustment method of the light adjustment structure 4000, thereby ensuring the overall display effect of the display module 10.

[0078] Figure 11 is Figure 1 The second enlarged schematic diagram of area A in the figure, refer to Figure 1 and Figure 11 As shown in the figure, the light adjustment structure 4000 includes a plurality of light adjustment units 4200; along the first direction X1, the light-emitting element 2000 and the light adjustment unit 4200 at least partially overlap.

[0079] Among them, refer to Figure 11As shown, the light adjustment structure 4000 includes a plurality of light adjustment units 4200. Since the light adjustment structure 4000 is arranged to avoid the situation of over-bright or over-dark light at the seam where the light-emitting elements 2000 emit light, the light adjustment units 4200 overlap with the light-emitting elements 2000 in the first direction X1. Furthermore, the light adjustment units 4200 can effectively adjust the light emitted by adjacent light-emitting elements 2000, ensuring the balance between the seam of adjacent display panels 100 and the display of the display panel 100. Further, a plurality of light adjustment units 4200 arranged in the second direction X2 are attached to each other to avoid gaps that may affect the overall display effect of the display module 10.

[0080] Furthermore, referring to Figure 11 As shown, a plurality of light adjustment units 4200 arranged in the second direction X2 are integrally arranged.

[0081] Specifically, a plurality of light adjustment units 4200 arranged in the second direction X2 can be integrally arranged, which can simplify the manufacturing process of the display module 10 and reduce the manufacturing cost of the display module 10. Further, compared with the case where a plurality of light adjustment units 4200 are attached to each other, the integral arrangement of the light adjustment units 4200 can avoid gaps between adjacent light adjustment units 4200 and better ensure the overall display effect of the display module 10.

[0082] Continuing to refer to Figures 3 to 5 、 Figure 8 and Figure 9 As shown, in the thickness direction of the display panel 10, the height of the light adjustment structure 4000 is h1, and the thickness of the encapsulation layer 3000 is h2; satisfying: h1 ≤ h2.

[0083] Among them, referring to Figures 3 to 5 、 Figure 8 and Figure 9 As shown, the thickness of the encapsulation layer 3000 is greater than or equal to the thickness of the light adjustment structure 4000, that is, the added light adjustment structure 4000 of the display module 10 will not exceed the thickness of the encapsulation layer 3000 in the original display panel 100. Furthermore, the flatness of the overall display panel 100 can be ensured, and thus the flatness of the overall display module 10 can be ensured. Specifically, referring to Figure 8 and Figure 9 As shown, the height of the light adjustment structure 4000 is h1, and the thickness of the encapsulation layer 3000 is h2; satisfying: h1 = h2, or h1 < h2.

[0084] Figure 12 is Figure 11 the first cross-sectional schematic diagram along the cutting line D-D' in Figure 13 is Figure 11 the first cross-sectional schematic diagram along the cutting line E-E' inFigure 14 is Figure 11 the first cross-sectional schematic diagram along the section line F-F' in Figure 1 , Figures 11 to 14 As shown in and , along the second direction X2, two adjacent light ray adjustment units 4200 are arranged in a fitting manner; the light-emitting element 2000 includes a first light-emitting element 2100 and a second light-emitting element 2200, and the light-emitting wavelength of the first light-emitting element 2100 is greater than that of the second light-emitting element 2200; the light ray adjustment unit 4200 includes a first light ray adjustment unit 4210 and a second light ray adjustment unit 4220; along the first direction X1, the first light-emitting element 2100 and the first light ray adjustment unit 4210 at least partially overlap, and the second light-emitting element 2200 and the second light ray adjustment unit 4220 at least partially overlap; along the thickness direction of the display panel 10, the height of the first light ray adjustment unit 4210 is h11, and the height of the second light ray adjustment unit 4220 is h12; h11≥h12 is satisfied.

[0085] Furthermore, the light ray adjustment structure 4000 includes a plurality of light ray adjustment units 4200, and two light ray adjustment units 4200 arranged along the second direction X2 are arranged in a fitting manner, that is, the plurality of light ray adjustment units 4200 are not integrally arranged, and thus can be finely set according to the difference in the position where the light ray adjustment unit 4200 is located, that is, adaptively adjusted according to the different light-emitting colors of the adjacent light-emitting elements 2000, so as to ensure that the display effect of the display module 10 is more balanced and improve the overall display effect of the display module 10.

[0086] Specifically, as shown in Figures 11 to 13 , the light-emitting element 200 includes a first light-emitting element 2100 and a second light-emitting element 2200, and the light-emitting wavelength of the first light-emitting element 2100 is greater than that of the second light-emitting element 2200. Therefore, the light-emitting color of the first light-emitting element 2100 is different from that of the second light-emitting element 2200. Exemplarily, the first light-emitting element 2100 may be a red light-emitting element, and the second light-emitting element 2200 may be a blue light-emitting element. For the specific colors of the first light-emitting element 2100 and the second light-emitting element 2200, the embodiments of the present invention do not specifically limit them, and can be adaptively adjusted according to requirements.

[0087] Among them, the light adjustment unit 4200 includes a first light adjustment unit 4210 and a second light adjustment unit 4220. Along the first direction X1, the first light-emitting element 2100 and the first light adjustment unit 4210 at least partially overlap, that is, the light-emitting element 2000 adjacent to the first light adjustment unit 4210 is the first light-emitting element 2100, and the first light adjustment unit 4210 adjusts the light emitted by the first light-emitting element 2100; along the first direction X1, the second light-emitting element 2200 and the second light adjustment unit 4220 at least partially overlap, that is, the light-emitting element 2000 adjacent to the second light adjustment unit 4220 is the second light-emitting element 2200, and the second light adjustment unit 4220 adjusts the light emitted by the second light-emitting element 2200.

[0088] Specifically, when the heights of the light adjustment units 4200 are different, the refraction of the light transmitted to the light adjustment unit 4200 can also be set differently. Specifically, referring to Figures 12 to 14 As shown, along the thickness direction of the display panel 10, the height of the first light adjustment unit 4210 is h11, and the height of the second light adjustment unit 4220 is h12; h11≥h12 is satisfied, that is, the height of the first light adjustment unit 4210 is greater than or equal to the height of the second light adjustment unit 4220. In other words, when light of different wavelengths is transmitted to the light adjustment structure 4000 at different heights, the refraction angle of the light will be different. Therefore, the height difference between the first light adjustment unit 4210 and the second light adjustment unit 4220 can be set according to the wavelength difference between the first light-emitting element 2100 and the second light-emitting element 2200, so as to ensure the balance of the light adjustment of the light adjustment units 4200 at different positions and ensure the overall display effect of the display module 10.

[0089] Continue to refer to Figures 1 to 14 As shown, the orthographic projection of the light adjustment structure 4000 on the array substrate 1000 does not overlap with the orthographic projection of the light-emitting element 2000 on the array substrate 1000.

[0090] Specifically, referring to Figures 2 to 14 As shown, there is a gap between the orthographic projection of the light adjustment structure 4000 on the array substrate 1000 and the orthographic projection of the light-emitting element 2000 on the array substrate 1000. In this way, the interference of the set light adjustment structure 4000 on the normal display of the light-emitting element 2000 can be avoided, so as to ensure the display effect of the display panel 100 and improve the overall display effect of the display module 10.

[0091] Figure 15 is Figure 1 the third enlarged schematic diagram of area A in Figure 16 is Figure 15The first cross-sectional schematic diagram along the section line G-G' in Figure 17 is Figure 15 The first cross-sectional schematic diagram along the section line F-F' in Figures 15 to 17 As shown in the reference

[0092] Specifically, referring to the reference Figures 15 to 17 As shown, the light-emitting element 200 includes a third light-emitting element 2300 and a fourth light-emitting element 2400. The light-emitting wavelength of the third light-emitting element 2300 is greater than that of the fourth light-emitting element 2400. Therefore, the light-emitting color of the third light-emitting element 2300 is different from that of the fourth light-emitting element 2400. For the specific colors of the third light-emitting element 2300 and the fourth light-emitting element 2400, the embodiments of the present invention do not specifically limit them, and can be adaptively adjusted according to requirements.

[0093] Among them, the light ray adjusting unit 4200 includes a third light ray adjusting unit 4230 and a fourth light ray adjusting unit 4240. Among them, along the first direction X1, the third light-emitting element 2300 and the third light ray adjusting unit 4230 at least partially overlap, that is, the light-emitting element 2000 adjacent to the third light ray adjusting unit 4230 is the third light-emitting element 2300, and the third light ray adjusting unit 4230 adjusts the light emitted by the third light-emitting element 2300; along the first direction X1, the fourth light-emitting element 2400 and the fourth light ray adjusting unit 4240 at least partially overlap, that is, the light-emitting element 2000 adjacent to the fourth light ray adjusting unit 4240 is the fourth light-emitting element 2400, and the fourth light ray adjusting unit 4240 adjusts the light emitted by the fourth light-emitting element 2400.

[0094] Specifically, when the distances between the light ray adjusting unit 4200 and the adjacent light-emitting elements 2000 are different, the refraction conditions of the light rays transmitted to the light ray adjusting unit 4200 can also be set differently. Specifically, referring to the referenceFigures 15 to 17 As shown, the gap between the orthographic projection of the third light ray adjustment unit 4230 onto the array substrate 1000 and the orthographic projection of the third light-emitting element 2300 onto the array substrate 1000 is d1, and the gap between the orthographic projection of the fourth light ray adjustment unit 4240 onto the array substrate 1000 and the orthographic projection of the fourth light-emitting element 2400 onto the array substrate 1000 is d2; it satisfies d1≥d2, that is, the distance between the third light ray adjustment unit 4230 and the adjacent light-emitting element 2000 is less than the distance between the fourth light ray adjustment unit 4240 and the adjacent light-emitting element 2000. In other words, light rays of different wavelengths are transmitted to light ray adjustment structures 4000 at different distances, and the refraction angles of the light rays will be different. Therefore, the gaps between the third light ray adjustment unit 4230 and the fourth light ray adjustment unit 4240 and the light-emitting element 2000 can be differentially set according to the wavelength differences of the third light-emitting element 2300 and the fourth light-emitting element 2400, so as to ensure the balance of the light ray adjustment by the light ray adjustment units 4200 at different positions and ensure the overall display effect of the display module 10.

[0095] Figure 18 is Figure 1 the fourth enlarged schematic diagram of area A in Figure 19 is Figure 18 the first cross-sectional schematic diagram along the section line H-H' in Figure 20 is Figure 18 the first cross-sectional schematic diagram along the section line I-I' in Figures 18 to 20 As shown, along the second direction X2, two adjacent light ray adjustment units 4200 are arranged in a fitting manner; the light-emitting element 2000 includes a fifth light-emitting element 2500 and a sixth light-emitting element 2600, and the light-emitting wavelength of the fifth light-emitting element 2500 is greater than that of the sixth light-emitting element 2600; the light ray adjustment unit 4200 includes a fifth light ray adjustment unit 4250 and a sixth light ray adjustment unit 4260; along the first direction X1, the fifth light-emitting element 2500 and the fifth light ray adjustment unit 4250 at least partially overlap, and the sixth light-emitting element 2600 and the sixth light ray adjustment unit 4260 at least partially overlap; in the first state, the refractive index of the fifth light ray adjustment unit 4250 is n1a, and the refractive index of the sixth light ray adjustment unit 4260 is n1b, satisfying n1a≥n1b.

[0096] Specifically, referring to Figures 18 to 20As shown, the light-emitting element 200 includes a fifth light-emitting element 2500 and a sixth light-emitting element 2600. The light-emitting wavelength of the fifth light-emitting element 2500 is greater than that of the sixth light-emitting element 2600. Therefore, the light-emitting color of the fifth light-emitting element 2500 is different from that of the sixth light-emitting element 2600. Regarding the specific colors of the fifth light-emitting element 2500 and the sixth light-emitting element 2600, the embodiments of the present invention do not make specific limitations and can be adaptively adjusted according to requirements.

[0097] Among them, the light adjustment unit 4200 includes a fifth light adjustment unit 4250 and a sixth light adjustment unit 4260. Along the first direction X1, the fifth light-emitting element 2500 and the fifth light adjustment unit 4250 at least partially overlap, that is, the light-emitting element 2000 adjacent to the fifth light adjustment unit 4250 is the fifth light-emitting element 2500, and the fifth light adjustment unit 4250 adjusts the light emitted by the fifth light-emitting element 2500; along the first direction X1, the sixth light-emitting element 2600 and the sixth light adjustment unit 4260 at least partially overlap, that is, the light-emitting element 2000 adjacent to the sixth light adjustment unit 4260 is the sixth light-emitting element 2600, and the sixth light adjustment unit 4260 adjusts the light emitted by the sixth light-emitting element 2600.

[0098] Specifically, by adjusting the refractive indices of the light adjustment units 4200 adjacent to different light-emitting elements 2000 to be different, it is also possible to differentially set the refraction conditions of the light transmitted to the light adjustment unit 4200, thereby ensuring the overall display effect of the display module 10. Specifically, referring to Figures 15 to 17 As shown, in the first state, the refractive index of the fifth light adjustment unit 4250 is n1a, and the refractive index of the sixth light adjustment unit 4260 is n1b, satisfying n1a ≥ n1b. That is, in the first state, the fifth light adjustment unit 4250 is different from the sixth light adjustment unit 4260, and the fifth light adjustment unit 4250 is greater than the sixth light adjustment unit 4260. Similarly, in the second state, the fifth light adjustment unit 4250 and the sixth light adjustment unit 4260 can also be adjusted to be different, and the fifth light adjustment unit 4250 is greater than the sixth light adjustment unit 4260. In other words, when light of different wavelengths is transmitted to the light adjustment structure 4000 with different refractive indices, the refraction angles of the light will be different. Therefore, the refractive indices of the fifth light adjustment unit 4250 and the sixth light adjustment unit 4260 can be set according to the wavelength differences of the fifth light-emitting element 2500 and the sixth light-emitting element 2600, so as to ensure the balance of the light adjustment of the light adjustment units 4200 at different positions and ensure the overall display effect of the display module 10.

[0099] Referring to Figures 2 to 20As shown, the light adjustment structure 4000 includes a flat surface 4000a and a curved surface 4000b that are connected to each other. The flat surface 4000a is disposed in contact with at least a part of the array substrate 1000, and the curved surface 4000b is curved away from the array substrate 1000.

[0100] Specifically, referring to Figures 2 to 20 As shown, the light adjustment structure 4000 includes a flat surface 4000a and a curved surface 4000b, wherein the curved surface 4000b is curved away from the array substrate 1000, and the flat surface 4000a is connected to the curved surface 4000b. Therefore, the light adjustment structure 4000 can be understood as a semi-circular structure. For the specific curvature of the curved surface 4000b, it can be adaptively adjusted according to actual needs, and the embodiments of the present invention do not specifically limit this.

[0101] Among them, the flat surface 4000a in the light adjustment structure 4000b is disposed in contact with at least a part of the array substrate 1000. This can be understood as that the area where the flat surface 4000a is in contact with the array substrate 1000 is the side where the light adjustment structure 4000b overlaps the array substrate 1000. In the figure, an example is given where the flat surface 4000a overlaps the light shielding module 6000; the area where the flat surface 4000a is not in contact with the array substrate 1000 can be understood as the seam between two adjacent display panels 100. The light adjustment structure 4000b is shown in a semi-circular form. Therefore, the light adjustment structure 4000b can be understood as a convex lens, which is used to adjust the light transmitted to the light adjustment structure 4000, so as to ensure the overall display effect of the display module 10.

[0102] Figure 21 is an enlarged schematic diagram of two light adjustment structures provided by the embodiments of the present invention. Referring to Figure 21 As shown, the light adjustment structure 4000 further includes a plurality of light adjustment convex structures 4000c disposed on the curved surface 4000b; the light convex structure 4000c includes a sub-curved surface 4000d, and the sub-curved surface 4000d is curved away from the array substrate 1000.

[0103] Furthermore, referring to Figure 21 As shown, the light adjustment structure 4000 may further include at least one light convex structure 4000c, wherein the sub-curved surface 4000d of the light convex structure 4000c is curved away from the array substrate 1000. Combining Figure 21 It can be seen that the light convex structure 4000c is semi-circular in shape, which is equivalent to setting more small semi-circular shapes on the surface of the originally semi-circular light adjustment structure 4000, further enhancing the light adjustment effect of the light adjustment structure 4000, so as to better ensure the overall display effect of the display module 10.

[0104] Based on the same inventive concept, an embodiment of the present invention further provides a display device. Figure 22 FIG. Figure 22 is a schematic structural diagram of a display device provided by an embodiment of the present invention.
