Summary of the Invention

[0003] This invention provides a display module and a display device. By setting a light adjustment structure in the display module and adjusting the refractive index of the light adjustment structure according to the different luminous brightness of the light-emitting element, the display effect of the display module is improved.

[0004] In a first aspect, embodiments of the present invention provide a display module, including at least two display panels;

[0005] The display panel includes:

[0006] Array substrate;

[0007] A light-emitting element is located on one side of the array substrate; the light-emitting element includes a first state and a second state, wherein the brightness of the light-emitting element in the first state is greater than the brightness of the light-emitting element in the second state;

[0008] An encapsulation layer is located on the side of the light-emitting element away from the array substrate;

[0009] The display panel includes a first display panel and a second display panel, and the first display panel and the second display panel are arranged along a first direction;

[0010] The display module further includes a light adjustment structure located on the side of the encapsulation layer near the array substrate; the light adjustment structure is located between the first display panel and the second display panel, and overlaps with at least a portion of the first display panel and at least a portion of the second display panel; the light adjustment structure extends along a second direction.

[0011] The display module also includes adjustment wires that extend along the thickness direction of the array substrate and are connected to the light adjustment structure.

[0012] In the first state, the refractive index of the light adjustment structure is n1; in the second state, the refractive index of the light adjustment structure is n2, satisfying: n1 > n2;

[0013] The first direction and the second direction intersect and are parallel to the plane of the array substrate.

[0014] Secondly, based on the same inventive concept, embodiments of the present invention provide a display device including the display module described in the first aspect.

[0015] This invention provides a display module comprising multiple display panels, a light adjustment structure, and adjustment wires. Each display panel includes an array substrate, light-emitting elements, and an encapsulation layer. The light-emitting elements have a first state and a second state, where the brightness of the light-emitting element in the first state is greater than that in the second state. The display module includes a first display panel and a second display panel. The light adjustment structure is located on the side of the encapsulation layer near the array substrate and between the first and second display panels, overlapping with both panels. In other words, the light adjustment structure is positioned at the seam between the first and second display panels and overlaps with them. Furthermore, the adjustment wires are connected to the light adjustment structure and adjust its refractive index in conjunction with the 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 conjunction with the different brightness levels of the display panels, thus avoiding significant display differences at the seam between the display panels and improving the overall display uniformity of the display module, thereby enhancing its display effect.

Figure 2yes Figure 1 The first enlarged schematic diagram of region A in the middle. Figure 3 yes Figure 2 A schematic diagram of the first type of cross-section along section line B-B'. Figure 4 This is a first cross-sectional schematic diagram of the light-emitting element in a first state according to an embodiment of the present invention. Figure 5 This is a second cross-sectional schematic diagram of the light-emitting element in the first state according to an embodiment of the present invention, for reference. Figures 1 to 5 As shown, this embodiment of the invention provides a display module 10, which includes at least two display panels 100. Each display panel 100 includes: an array substrate 1000; light-emitting elements 2000 located on one side of the array substrate 1000; the light-emitting elements 2000 having a first state and a second state, wherein the brightness of the light-emitting elements 2000 in the first state is greater than the brightness of the light-emitting elements 2000 in the second state; and an encapsulation layer 3000 located on the side of the light-emitting elements 2000 away from the array substrate 1000. The display panels 100 include a first display panel 101 and a second display panel 102, which are arranged along a first direction X1. The display module 10 also includes a light adjustment structure 4000 located on the encapsulation layer. 3000 is located on the side 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 with at least a portion of the first display panel 101 and at least a portion of the second display panel 102 respectively; the light adjustment structure 4000 extends along the second direction X2; the display module 10 also includes an adjustment wire 5000, which extends along the thickness direction of the array substrate 1000 and 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] The display module 10 includes a display panel 100, which has a display function, thereby achieving the display effect of the display module 10. Furthermore, the display module 10 includes multiple display panels 100, which can be combined and spliced ​​to achieve a large-size display effect, ensuring a better overall display effect for the display module 10. For example, Figure 1 The example of the display module 10 includes two display panels 100. The specific number of display panels 100 in the display module 10 can be adjusted according to actual needs. This embodiment of the invention does not impose a specific limitation on this.

[0045] Further reference Figures 1 to 3 As shown, the display panel 100 includes an array substrate 1000 and light-emitting elements 2000 disposed on one side of the array substrate 1000. By driving the light-emitting elements 2000 to emit light, the display panel 100 achieves its display function, thereby realizing the display function of the display module 10. The light-emitting element 2000 has a first state and a second state. In the first state, the brightness of the light-emitting element 2000 is greater than that in the second state. Comparing the first and second states, 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. The specific brightness values ​​of the light-emitting element 2000 in the first and second states are not limited in this embodiment. Furthermore, the display panel 100 also includes an encapsulation layer 3000, which is used to encapsulate and protect the display panel 100, while also ensuring the overall flatness of the display panel 100.

[0046] For details, please refer to Figure 2 and Figure 3 As shown, the display panel 100 includes a first display panel 101 and a second display panel 102, wherein the first display panel 101 and the second display panel 102 are arranged along a first direction X1. The display module 10 includes a light adjustment structure 4000 extending along a second direction X2, the light adjustment structure 4000 being located between the first display panel 101 and the second display panel 102, that is, the light adjustment structure 4000 being located at the seam between the first display panel 101 and the second display panel 102. Further, refer to... Figure 2 and Figure 3 As shown, the light adjustment structure 4000 overlaps with at least a portion of the first display panel 101 and at least a portion of the second display panel 102, respectively. 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 edge of the adjacent display panels 100.

[0047] Furthermore, the light adjustment structure 4000 is located on the side of the encapsulation layer 3000 near the array substrate 1000, as shown in the reference. Figure 3 As shown, the area where the light adjustment structure 4000 overlaps with the display panel 100 is also covered by the subsequently fabricated encapsulation layer 3000. The encapsulation layer 3000 ensures the structural stability of the light adjustment structure 4000 and the overall structural stability of the display module 10, as well as the flatness of the display panel 100 and the display module 10 as a whole. Thus, the addition of the light adjustment structure 4000 will not cause any protrusions in the display panel 100.

[0048] Further reference Figures 1 to 3 As shown, the display module 10 also includes an adjustment wire 5000, which is connected to the light adjustment structure 4000. The adjustment wire 5000 can transmit different temperature or current signals to the light adjustment structure 4000 depending on the brightness state of the light-emitting element 2000, such as the first state or the second state. The light adjustment structure 4000 adjusts the refractive index accordingly, thereby ensuring the overall display effect of the display module 10. The array substrate 1000 includes stacked metal layers and insulating layers. The adjustment wire 5000 can be electrically connected to the corresponding metal layer by drilling holes in the array substrate 1000 through the light adjustment structure 4000, thereby realizing the transmission of relevant signals. The specific film layer configuration in the array substrate 1000 can be adaptively added or removed according to actual needs; this embodiment of the invention does not impose specific limitations on this.

[0049] For example, when the light-emitting element 2000 achieves different luminous brightness, the corresponding driving current transmitted to the light-emitting element 2000 is different. The relevant current signal can be transmitted to the light adjustment structure 4000 through the adjusting wire 5000. The light adjustment structure 4000 adjusts the refractive index according to different electrical signals (e.g., current or voltage). The material of the light adjustment structure 4000 can be an electrochromic crystal. Alternatively, when the light-emitting element 2000 achieves different luminous brightness, the heat generated by the light-emitting element 2000 due to luminescence is different. Different amounts of heat can be transmitted to the light adjustment structure 4000 through the adjusting wire 5000 or through the encapsulation layer 3000, etc. The light adjustment structure 4000 adjusts the refractive index according to different temperature values. Optionally, the light adjustment structure 4000 can be doped with particles whose refractive index changes with temperature.

[0050] Specifically, in the display module 10, the area where the light adjustment structure 4000 is located is originally the seam between the two display panels 100, where there is an air gap. Without the light adjustment structure 4000, the difference in refractive index between the air gap and the film layer structure at the seam would cause some of the light emitted by the light-emitting elements 2000 near the seam of the display panel 100 to undergo total internal reflection, resulting in reduced brightness at the seam and affecting the overall display uniformity of the display module 10. (Reference) Figures 2 to 4As shown, by setting 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, and further, by making the shape of the light adjustment structure 4000 equivalent to a convex lens, the light adjustment can be better achieved. This allows light emitted from the light-emitting element 2000 near the seam to 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] Furthermore, the display module 10 provided in this embodiment of the invention can also adjust the refractive index of the light adjustment structure 4000 more precisely according to the different brightness of the light-emitting element 2000, thereby ensuring that the display module 10 can guarantee the display effect 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 light adjustment structure 4000, more light can be transmitted through the seam, achieving a balance between the seam and the display panel 100. Optionally, in the second state, the light-emitting element 2000 may not emit light or may have a lower brightness. It should be noted that... Figure 4 and Figure 5 You can compare and refer to them. Figure 4 The luminous brightness of the 2000 light-emitting element should be greater than Figure 5 The luminous brightness of the 2000 light-emitting element in the middle. Figure 4 The refractive index of the 4000 mid-ray adjustment structure is greater than Figure 5 The refractive index of the ray-adjusting structure is 4000. Figure 4 and Figure 5 In the image, the arrow can be interpreted as the adjustment of the light transmission path to the light adjustment structure 4000.

[0052] Optional, see reference Figure 2 As shown, the display panel 100 also 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 embodiments of the present invention do not impose specific limitations on this.

[0053] Optionally, the light-emitting element 2000 in the display panel 100 can be a micro light-emitting element or a mini light-emitting element, etc., and the embodiments of the present invention do not impose specific limitations on it.

[0054] In summary, this embodiment of the invention provides a display module with an added light adjustment structure. The light adjustment structure is located at the seam between the first and second display panels and overlaps with them. Furthermore, an adjustment wire is connected to the light adjustment structure, which adjusts the refractive index of the light adjustment structure in conjunction with 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 conjunction with different display brightnesses of the display panels. This avoids large display differences between different display panels at the seam, thereby improving the overall display uniformity of the display module and ultimately enhancing its display effect.

[0055] Continue to refer to Figures 1 to 5 As shown, the display panel 100 also includes a light-blocking module 6000, which is located between two adjacent light-emitting elements 2000; the second state also includes a first sub-state, in which the light-emitting elements 2000 do 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; satisfying: |n3-na| / na≤20%.

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

[0057] The second state also includes a first sub-state, which can be understood as the light-emitting element 2000 not emitting light at all. Specifically, when the light-emitting element 2000 of the display module 10 is not emitting light (i.e., in the dark state), without the light adjustment structure 4000, some ambient light will escape from the seam due to the air gap and lack of film layer shielding. However, the display panel 100 has a light-blocking structure 6000, which can block some ambient light. This results in the display module 10 being brighter at the seam and the display panel 100 being darker in this state, affecting the overall display balance of the display module 10. Therefore, by setting the light adjustment structure 4000 and adjusting its refractive index, when the light-emitting element 2000 is not emitting light, the light coming from the seam can be diffused by the light adjustment structure 4000, avoiding concentrated light emission 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] Furthermore, 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 is not emitting light, the refractive index of the light adjustment structure 4000 is the same as or close to the refractive index of the encapsulation layer 3000. Therefore, when the light-emitting element 2000 is emitting light, the refractive index of the light adjustment structure 4000 can be adjusted to be greater than the refractive index of the encapsulation layer 3000. Furthermore, the shape of the light adjustment structure 4000 is equivalent to a convex lens, which can better achieve light adjustment. This can also be understood as follows: when the display module 10 is in a dark state, the refractive index of the light adjustment structure 4000 is adjusted to the refractive index of the encapsulation layer 3000, and ambient light can be refracted through the light adjustment structure 400, thereby reducing the transmitted brightness of ambient light at the seam; when the display module 10 is in a bright state, the refractive index of the light adjustment structure 4000 is adjusted to be greater than the refractive index 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 This is a schematic diagram of the structure of the second display module provided in the embodiment of the present invention. Figure 7 This is a schematic diagram of the structure of the third display module provided in the embodiment of the present invention. Figure 8 yes Figure 2 A schematic diagram of the first type of cross-section along section line C-C', see reference. Figure 1 , Figure 2 , Figures 6 to 8 As shown, the array substrate 1000 includes a driving unit 1100, which 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, and the pixel driving circuit 1110 is electrically connected to the light-emitting element 2000. The display panel 100 includes a first region and a second region. The second region is located on one side of the first region, and the light-emitting element 2000 and the pixel driving circuit 1110 are located in the first region. The scanning driving circuit 1120 is located in the second region. The adjustment wire 5000 includes a voltage adjustment trace 5100, which 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 electrically connected to the pixel driving circuit 1110 in the second display panel 102.

[0060] For details, please refer 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 scan driving circuit 1120. The scan driving circuit 1120 is electrically connected to the pixel driving circuit 1110 and provides light emission signals and scan signals 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 based on the acquired signals, thereby driving the light-emitting element 2000 to emit light and display, thus realizing the display function of the display panel 100 and the display module 10. It should be noted that... Figure 6 and Figure 7 The specific connection routing is not shown.

[0061] Furthermore, the display panel 100 includes a first region and a second region, wherein the first region can be understood as the setting area corresponding to the light-emitting element 2000 and the pixel driving circuit 1110, and the second region can be understood as the setting area corresponding to the scan driving circuit 1120. Optionally, refer to Figure 6 and Figure 7 As shown, the multiple pixel driving circuits 1110 arranged along the first direction X1 are row pixel driving circuits. The scan driving circuit 1120 can provide electrical signals to the row pixel driving circuits arranged along the first direction X1. Therefore, the multiple scan driving circuits 1120 can be arranged between different row pixel driving circuits, such as... Figure 6 As shown; or multiple scan drive circuits 1120 are disposed at the edge of the display panel 100, such as Figure 7 As shown. The configuration of the scan drive circuit 1120 is diverse, therefore the specific division of the first and second regions is also diverse.

[0062] Further reference Figure 8 As shown, the pixel driving circuit 1110 includes at least one transistor 1111, which is electrically connected to the light-emitting element 2000 and provides driving current to 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; only a transistor 1111 is used as an example. Furthermore, the array substrate 1000 includes multiple stacked film layers, such as buffer layers, gate insulating layers, interlayer insulating layers, planarization layers, etc. The specific type and number of film layers in the array substrate 1000 can be adaptively adjusted according to different needs; this embodiment of the invention does not impose specific limitations here. Furthermore, Figure 8The transistor 1111 shown in the pixel driving circuit 1110 includes an active layer 1111a, a gate 1111b, a drain 1111c, and a source 1111d. The specific arrangement of the transistor 1111 can be adaptively adjusted according to requirements, and this embodiment of the invention does not impose specific limitations on this. Furthermore, the display panel 100 also includes a connection structure 1200, through which the light-emitting element 2000 can be electrically connected to the pixel driving circuit 1110.

[0063] For details, please refer to Figure 8 As shown, the adjustment wire 5000 includes a voltage adjustment trace 5100, which 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 electrically connected to the pixel driving circuit 1110 in the second display panel 102. The brightness of the light-emitting element 2000 is related to the current transmitted to it. Therefore, the light adjustment structure 4000 can be electrically connected to the pixel driving circuit 1110, and the refractive index of the light adjustment structure 4000 can be adjusted by combining the electrical signals provided to the light-emitting element 2000. Optionally, the display module 10 also includes a driver chip (not specifically shown in the figure). The driver chip transmits relevant electrical signals to the scan driving circuit 1120, and the light adjustment structure 4000 can also be electrically connected to the driver chip.

[0064] In summary, the light adjustment structure 4000 can adjust the refractive index by combining the light emission of the light-emitting element 2000 in the first display panel 101 and the light emission of the light-emitting element 2000 in the second display panel 102, thereby ensuring the overall display effect of the display module 10.

[0065] Furthermore, 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; wherein, n11>na≥n12, |n11-na|>|n12-na|.

[0066] 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, thereby ensuring 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 a first voltage V1 through the voltage adjustment trace 5100; in the second state, the light adjustment structure 4000 receives a second voltage V2 through the voltage adjustment trace 5100. When the light-adjusting structure 4000 acquires the first voltage V1, its refractive index is n11. When it acquires the second voltage V2, its refractive index is n12, satisfying the following conditions: n11 > na, na ≥ n12. That is, when the light-emitting element 2000 is in the first state, the light emission brightness is high. To avoid low brightness at the seam between the first display panel 101 and the second display panel 102, the refractive index of the light-adjusting 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 light emission brightness is dim. To avoid high brightness at the seam between the first display panel 101 and the second display panel 102, the refractive index of the light-adjusting 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|, meaning that 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. By combining the voltage value obtained from the light adjustment structure 4000 and further refining its refractive index adjustment, the regularity of the refractive index adjustment of the light adjustment structure 4000 can be ensured, reducing the implementation difficulty and guaranteeing the overall display effect of the display module 10.

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

[0069] Specifically, regarding the relationship between refractive index and voltage value: |n11-na|>|n12-na|, it can be (V1-V2)*(n11-n12)>0; or (V1-V2)*(n11-n12)<0. Where (V1-V2)*(n11-n12)>0, it can be understood that the input voltage value of the light adjustment structure 4000 can all be positive, that is, the first voltage V1 and the second voltage V2 are both positive (and V1>V2), or the first voltage V1 is positive and the second voltage is negative. Where V1-V2)*(n11-n12)<0, it can be understood that the input voltage value of the light adjustment structure 4000 can all be negative, that is, the first voltage V1 and the second voltage V2 are both negative (and V1>V2). For specific voltage input situations, adjustments can be made according to actual needs. This embodiment of the invention does not impose specific limitations, reflecting the diversity of refractive index adjustment of the light 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 multiple metal trace layers, and the connection trace 7000 and at least one metal trace layer are disposed on the same layer.

[0071] Further reference Figure 8 As shown, the display panel 100 includes connection traces 7000, which are disposed on the same layer as at least one metal trace layer in the pixel driving circuit 1110. The metal trace layer can be understood as the metal film layer containing the gate 1111b, drain 1111c, and source 1111d. Optionally, Figure 8 The 7000 intermediate connection trace is placed on the same layer as the 1111d source electrode. It should be noted that... Figure 8 This is a cross-sectional view, which does not show all the wiring connections, only those arranged in the same layer. By arranging the connecting traces 7000 and at least one layer of the metal trace layer in the same layer, the overall film thickness of the display module 10 can be effectively reduced. The traces arranged in the same layer can also be manufactured simultaneously, which helps to reduce the manufacturing cost of the display panel 10.

[0072] refer to Figure 2 and Figure 8 As shown, the orthographic projection of the connecting trace 7000 onto the array substrate 1000 at least partially overlaps with the orthographic projection of the light adjustment structure 4000 onto the array substrate 1000.

[0073] For details, please 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 connecting trace 7000 onto the array substrate 1000. In this way, by using space reuse, the space occupied by the traces in the display panel 100 can be reduced. The greater the space saved, the more light-emitting elements 2000 can be installed, improving the display effect of the display panel 100; or the saved space can provide larger wiring space for other traces, reducing signal interference between different traces, thereby ensuring the overall stability of the display module 10.

[0074] Figure 9 yes Figure 2 A schematic diagram of the second type of cross-section along section line C-C'. Figure 10 This is an enlarged schematic diagram of a light adjustment structure provided in an embodiment of the present invention, for reference. Figure 2 , Figure 9 and Figure 10 As shown, the light adjustment structure 4000 includes temperature-sensitive particles 4100; the adjustment wire 5000 includes temperature adjustment traces 5200, which include 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 element 2000 in the first display panel 101, and the second temperature adjustment trace is used to obtain the heat generated by the light-emitting element 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, reference Figure 8 and Figure 9 As shown, the light adjustment structure 4000 includes temperature-sensitive particles 4100. These particles can adjust their refractive index according to the ambient temperature, thus enabling the light adjustment structure 4000 to change its refractive index under different temperature conditions. Specifically, when the light-emitting element 2000 is at different brightness levels, with varying heat transfer to the film layer (e.g., the encapsulation layer 3000), the refractive index of the light adjustment structure 4000 can be adaptively adjusted according to the temperature difference. This ensures that the refractive index of the light-emitting element 2000 in its first state is greater than that in its second state.

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

[0077] Specifically, in the first state, the light adjustment structure 4000 obtains a temperature of T1 through the temperature adjustment trace 5200; in the second state, the light adjustment structure 4000 obtains a temperature of T2 through the temperature adjustment trace 5200. When the light adjustment structure 4000 is at temperature T1, the corresponding refractive index is n13; when the light adjustment structure 4000 is at temperature T2, the corresponding refractive index is n14, satisfying: T1 > T2; n13 > n14. That is, when the light-emitting element 2000 is in the first state, the light brightness is high. To avoid 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 relatively high. When the light-emitting element 2000 is in the second state, the light brightness is relatively low. To avoid 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 relatively low. This demonstrates the versatility 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 yes Figure 1 The second enlarged diagram of region A in the middle is shown in the reference diagram. Figure 1 and Figure 11 As shown, 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, reference 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 that the light emitted by the light-emitting element 2000 is too bright or too dark at the seam, the light adjustment units 4200 overlap with the light-emitting element 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 uniformity between the seam of adjacent display panels 100 and the display of the display panel 100. Further, the plurality of light adjustment units 4200 arranged in the second direction X2 are arranged in a fitting manner to avoid gaps affecting the overall display effect of the display module 10.

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

[0081] Specifically, the 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 the plurality of light adjustment units 4200 are arranged in a fitting manner, 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, which can ensure the flatness of the overall display panel 100 and further ensure the flatness of the overall display module 10. 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 section line D-D' in Figure 13 is Figure 11 the first cross-sectional schematic diagram along the section line E-E' in Figure 14 yes Figure 11 A schematic diagram of the first type of cross-section along section line F-F', see reference. Figure 1 , Figures 11 to 14 As shown, along the second direction X2, two adjacent light adjustment units 4200 are attached together; the light-emitting element 2000 includes a first light-emitting element 2100 and a second light-emitting element 2200, the light emission wavelength of the first light-emitting element 2100 is greater than the light emission wavelength of the second light-emitting element 2200; 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 overlap at least partially, and the second light-emitting element 2200 and the second light adjustment unit 4220 overlap at least partially; 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; satisfying h11≥h12.

[0085] Furthermore, the light adjustment structure 4000 includes multiple light adjustment units 4200. Two light adjustment units 4200 arranged along the second direction X2 are attached together, meaning that the multiple light adjustment units 4200 are not integrated. This allows for fine-tuning based on the differences in the positions of the light adjustment units 4200, i.e., adaptive adjustment based on the different light colors emitted by adjacent light-emitting elements 2000. This ensures a more balanced display effect for the display module 10 and improves the overall display effect of the display module 10.

[0086] For details, please refer to Figures 11 to 13 As shown, the light-emitting element 200 includes a first light-emitting element 2100 and a second light-emitting element 2200. The light emission wavelength of the first light-emitting element 2100 is greater than that of the second light-emitting element 2200. Therefore, the light emission color of the first light-emitting element 2100 is different from that of the second light-emitting element 2200. For example, the first light-emitting element 2100 can be a red light-emitting element and the second light-emitting element 2200 can be a blue light-emitting element. The specific colors of the first light-emitting element 2100 and the second light-emitting element 2200 are not specifically limited in this embodiment of the invention, and can be adapted to meet the requirements.

[0087] 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, the refraction of light transmitted to the light adjustment unit 4200 can be differentiated depending on its height. For details, please refer 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; satisfying h11≥h12, 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 structures 4000 at different heights, the refraction angle of the light will be different. Because the heights of the first light adjustment unit 4210 and the second light adjustment unit 4220 can be differentiated according to the wavelength difference between the first light-emitting element 2100 and the second light-emitting element 2200, the light adjustment units 4200 at different positions can be balanced, thus ensuring 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 onto the array substrate 1000 does not overlap with the orthographic projection of the light-emitting element 2000 onto the array substrate 1000.

[0090] For details, please refer to Figures 2 to 14 As shown, there is a gap between the orthographic projection of the light adjustment structure 4000 onto the array substrate 1000 and the orthographic projection of the light-emitting element 2000 onto the array substrate 1000. This can prevent the light adjustment structure 4000 from interfering with the normal display of the light-emitting element 2000, thereby ensuring the display effect of the display panel 100 and improving the overall display effect of the display module 10.

[0091] Figure 15 yes Figure 1 The third enlarged diagram of region A in the middle, Figure 16 yes Figure 15A schematic diagram of the first type of cross-section along section line G-G'. Figure 17 yes Figure 15 A schematic diagram of the first type of cross-section along section line F-F', see reference. Figures 15 to 17 As shown, along the second direction X2, two adjacent light adjustment units 4200 are attached together; the light-emitting element 2000 includes a third light-emitting element 2300 and a fourth light-emitting element 2400, the light emission wavelength of the third light-emitting element 2300 is greater than the light emission wavelength of the fourth light-emitting element 2400; the light adjustment unit 4200 includes a third light adjustment unit 4230 and a fourth light adjustment unit 4240; along the first direction X1, the third light-emitting element 2300 and the third light adjustment unit 4230 overlap at least partially, and the fourth light-emitting element 2400 and the fourth light adjustment unit 4240 overlap at least partially; the gap between the orthographic projection of the third light 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 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; satisfying d1≥d2.

[0092] For details, please refer to 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 emission wavelength of the third light-emitting element 2300 is greater than that of the fourth light-emitting element 2400. Therefore, the light emission color of the third light-emitting element 2300 is different from that of the fourth light-emitting element 2400. The specific colors of the third light-emitting element 2300 and the fourth light-emitting element 2400 are not specifically limited in this embodiment of the invention, and can be adaptively adjusted according to requirements.

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

[0094] Specifically, even when the distance between the light adjustment unit 4200 and the adjacent light-emitting element 2000 varies, the refraction of light transmitted to the light adjustment unit 4200 can be differentiated. For details, refer to... Figures 15 to 17 As shown, the gap between the orthographic projection of the third light 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 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; satisfying d1≥d2, that is, the distance between the third light adjustment unit 4230 and the adjacent light-emitting element 2000 is less than the distance between the fourth light adjustment unit 4240 and the adjacent light-emitting element 2000. In other words, when light of different wavelengths is transmitted to light adjustment structures 4000 at different distances, the refraction angle of the light will be different. Because the gap between the third light adjustment unit 4230 and the fourth light adjustment unit 4240 and the light-emitting element 2000 can be differentiated according to the wavelength difference between the third light-emitting element 2300 and the fourth light-emitting element 2400, the light adjustment units 4200 at different positions have uniformity in adjusting the light, thus ensuring the overall display effect of the display module 10.

[0095] Figure 18 yes Figure 1 The fourth enlarged diagram of region A in the middle, Figure 19 yes Figure 18 A schematic diagram of the first type of cross-section along section line H-H'. Figure 20 yes Figure 18 A schematic diagram of the first type of section along section line I-I', see reference. Figures 18 to 20 As shown, along the second direction X2, two adjacent light adjustment units 4200 are attached together; the light-emitting element 2000 includes a fifth light-emitting element 2500 and a sixth light-emitting element 2600, the light emission wavelength of the fifth light-emitting element 2500 is greater than the light emission wavelength of the sixth light-emitting element 2600; 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 overlap at least partially, and the sixth light-emitting element 2600 and the sixth light adjustment unit 4260 overlap at least partially; 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.

[0096] For details, please refer 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 emission wavelength of the fifth light-emitting element 2500 is greater than that of the sixth light-emitting element 2600. Therefore, the light emission color of the fifth light-emitting element 2500 is different from that of the sixth light-emitting element 2600. The specific colors of the fifth light-emitting element 2500 and the sixth light-emitting element 2600 are not specifically limited in this embodiment of the invention, and can be adaptively adjusted according to requirements.

[0097] 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 index of the light adjustment units 4200 adjacent to different light-emitting elements 2000, the refraction of light transmitted to the light adjustment unit 4200 can be differentiated, thereby ensuring the overall display effect of the display module 10. For details, refer 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 and the sixth light adjustment unit 4260 are adjusted to be different, 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 structures 4000 with different refractive indices, the refraction angle of the light will be different. This is because the refractive indices of the fifth light adjustment unit 4250 and the sixth light adjustment unit 4260 can be set according to the wavelength difference between the fifth light-emitting element 2500 and the sixth light-emitting element 2600, thereby ensuring that the light adjustment by the light adjustment units 4200 at different positions has a balance, and ensuring the overall display effect of the display module 10.

[0099] refer to Figures 2 to 20As shown, the light adjustment structure 4000 includes a plane 4000a and an arc surface 4000b connected to each other. The plane 4000a is attached to at least a portion of the array substrate 1000, and the arc surface 4000b is bent toward the side away from the array substrate 1000.

[0100] For details, please refer to Figures 2 to 20 As shown, the light adjustment structure 4000 includes a plane 4000a and an arc surface 4000b, wherein the arc surface 4000b is curved away from the array substrate 1000. The plane 4000a is connected to the arc surface 4000b, so the light adjustment structure 4000 can be understood as a semi-circular structure. The specific curvature of the arc surface 4000b can be adaptively adjusted according to actual needs, and the embodiments of the present invention do not impose specific limitations on this.

[0101] In the light adjustment structure 4000b, the plane 4000a is bonded to at least a portion of the array substrate 1000. This can be understood as the area where the plane 4000a is bonded to the array substrate 1000 being one side of the light adjustment structure 4000b. For example, the figure shows the plane 4000a bonded to one side of the light-blocking module 6000. The area where the plane 4000a is not bonded to 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. This light adjustment structure 4000b can be understood as a convex lens used to adjust the light transmitted to it, thereby ensuring the overall display effect of the display module 10.

[0102] Figure 21 This is an enlarged schematic diagram of two light adjustment structures provided in the embodiments of the present invention, for reference. Figure 21 As shown, the light adjustment structure 4000 also includes a plurality of light adjustment protrusions 4000c disposed on the arc surface 4000b; the light protrusions 4000c include a sub-arc surface 4000d, which is bent toward the side away from the array substrate 1000.
