[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be fully described below in combination with the drawings in the embodiments of the present invention through specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work fall within the protection scope of the present invention.

[0023] The inventors have found that in the prior art, when preparing a borderless display panel, the distance between the edge of the display panel and the display area is difficult to reduce due to the influence of various processes in the side wiring preparation process, making it difficult to reduce the border of the display panel. On the other hand, when multiple display panels are spliced, the distance between the seams is difficult to reduce due to the influence of the splicing accuracy. The wide border of the display panel and the large seam distance will cause the light information of the two adjacent display panels to be discontinuous with the light output at the seam position, thereby causing dark lines to appear at the seam position, affecting the display effect of the display panel.

[0024] Figure 1 is a structural schematic diagram of a display module provided by an embodiment of the present invention, Figure 2 yes Figure 1 A schematic diagram of a cross-sectional structure along the A-A' direction. Figure 1 and Figure 2 As shown, the display module provided by the embodiment of the present invention includes at least two display panels 10, a fill light component 20, a driving component 30 and at least one detector 40. A seam area S1 is provided between two adjacent display panels 10. The fill light component 20 is located in the seam area S1, and the side of the fill light component 20 facing the light emitting side of the display panel includes a plurality of first light emitting elements 210. The driving component 30 is electrically connected to the detector 40 and the fill light component 20, respectively, and is used to adjust the fill light information of the fill light component 20 according to the light emitting information of the two adjacent display panels detected by the detector 40.

[0025] Specifically, Figure 1 and Figure 2As shown, the display module includes at least two display panels 10 and at least one fill light component 20. Among them, the display panel 10 is used to realize picture display, and the fill light component 20 is located between two adjacent display panels 10, and is used to fill light for the seam area S1 of the two adjacent display panels 10. Exemplarily, the display panel 10 includes a first surface 110, a second surface 120 and a third surface 130. Among them, the first surface 110 is arranged adjacent to the second surface 120, and the first surface 110 is arranged opposite to the third surface 130. The first surface 110 of the display panel 10 can be the front side of the display panel 10, and the first surface 110 of the display panel 10 includes a display area, and the display area includes a plurality of light-emitting elements 01, and the plurality of light-emitting elements 01 emit light to realize picture display. The first surface 110 of the display panel 10 is also provided with a plurality of signal lines (not shown in the figure). The signal line may include at least one of a scan signal line, a data signal line, a positive power signal line, a negative power signal line and a reset signal line. Specifically, if the signal line includes a scan signal line and a data signal line, then in the display area, the extension direction of the plurality of scan signal lines intersects with the extension direction of the plurality of data signal lines, and the plurality of data signal lines and the plurality of scan signal lines are electrically connected to the light-emitting element 01, thereby providing the light-emitting element 01 with a data signal and a scan signal to ensure the normal operation of the light-emitting element 01. The second surface 120 of the display panel 10 may be a side surface of the display panel 10, and two adjacent display panels 10 are spliced ​​with each other through the second surface 120, that is, there is a splicing area S1 between the second surfaces 120 of the two adjacent display panels 10. The third surface 130 of the display panel 10 may be the back surface of the display panel, that is, the third surface 130 of the display panel 10 is located on the non-light-emitting side of the display panel 10. A binding pad setting area may be provided on the third surface 130 of the display panel 10, and the binding pads of the binding pad setting area are electrically connected to the signal lines of the first surface 110 through the side routing located on the second surface 120. Then, the driving signal is transmitted to the signal lines of the first surface 110 through the binding pads.

[0026] In addition, the display module also includes a driving component 30 and at least one detector 40. The detector 40 is at least located on the display panel 10, and is used to detect the light information of two adjacent display panels 10. The driving component 30 is electrically connected to at least one detector 40 and the fill light component 20, respectively, and then the driving component 30 adjusts the fill light information of the fill light component 20 according to the light information on the two adjacent display panels 10 detected by the detector 40. Exemplarily, when it is detected that the average value of the light information of the two adjacent display panels 10 is M1, the driving component 30 adjusts the fill light information (light information) of the fill light component 20 to approach M1, so that the light information of the seam area S1 after fill light is consistent with the light information of the two adjacent display panels 10, so as to realize the intelligent fill light of the seam area S1, improve the dark line phenomenon of the display module in the seam area S1, and enhance the display effect of the display module.

[0027] It should be noted that Figure 2 The example in which the driving component 30 is located on the non-light-emitting side of the fill light component 20 is used for illustration only. However, the embodiment of the present invention does not limit the location and number of the driving component 30 , and those skilled in the art can set them as needed.

[0028] It should also be noted that the detector 40 can be located on the light-emitting side of the display panel 10 or the fill light component 20 . The embodiment of the present invention does not limit the specific film layer relationship of the detector 40 , as long as it can detect the light-emitting information of the display panel 10 or the fill light component 20 .

[0029] In summary, the embodiment of the present invention provides a fill light component in the seam area between two adjacent display panels, and the fill light component includes a plurality of first light-emitting elements, and the plurality of first light-emitting elements emit light to enable the fill light component to fill light the seam area. In addition, the display module is also provided with a driving component and at least one detector, and the detector is used to detect the light emission information of the two adjacent display panels, and the driving component is electrically connected to the fill light component and the at least one detector, respectively. The driving component adjusts the fill light information of the plurality of first light-emitting elements on the fill light component according to the light emission information of the two adjacent display panels, so that the light emission information of the seam area tends to be consistent with the light emission information of the two adjacent display panels, thereby realizing intelligent fill light in the seam area, improving the dark line phenomenon of the display module in the seam area, and enhancing the display effect of the display module.

[0030] It is understandable that the light output information may include brightness information and chromaticity information. Specifically, the driving component 30 is used to adjust the brightness of the fill light component 20 according to the brightness information of the two adjacent display panels 10 detected by the detector 40, and / or the driving component 30 is used to adjust the chromaticity of the fill light component 20 according to the chromaticity information of the two adjacent display panels 10 detected by the detector 40. For example, when the average value of the brightness information of the two adjacent display panels 10 detected by the detector 40 is L1, the driving component 30 adjusts the brightness of the fill light component 20 to be close to L1, so as to achieve the brightness adjustment of the fill light component 20. Or when the average value of the chromaticity information of the two adjacent display panels 10 detected by the detector 40 is M1, the driving component 30 adjusts the chromaticity of the fill light component 20 to be close to M1, so as to achieve the chromaticity adjustment of the fill light component 20.

[0031] It should be noted that the multiple first light-emitting elements 210 include red light-emitting elements, green light-emitting elements, and blue light-emitting elements. When the fill light component 20 is adjusted in brightness, since the determining factor of the brightness information is irrelevant to the light-emitting color of the first light-emitting elements 210, the brightness of the fill light component 20 can be adjusted by simultaneously adjusting the brightness of the multiple first light-emitting elements 210. When the fill light component 20 is adjusted in chromaticity, since the chromaticity of the fill light component 20 is jointly determined by the chromaticities of light-emitting elements of different colors, it is necessary to separately adjust the first light-emitting elements 210 of different light-emitting colors to achieve chromaticity adjustment of the fill light component 20. For example, when the average value of the chromaticity information of the red light of two adjacent display panels 10 detected by the detector 40 is X1, the average value of the chromaticity information of the green light is Y1, and the average value of the chromaticity information of the blue light is Z1, the driving component 30 adjusts the chromaticity of the red light emitting element in the first light emitting element 210 to approach X1, the chromaticity of the green light emitting element to approach Y1, and the chromaticity of the blue light emitting element to approach Z1, so as to achieve chromaticity adjustment of the fill light component 20. In this way, by distinguishing the overall adjustment under the brightness information and the individual adjustment under the chromaticity information, the fill light component 20 can be accurately adjusted under different light output information, thereby improving the fill light effect of the fill light component 20.

[0032] Optionally, based on the above embodiment, Figure 3 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Figure 2 and Figure 3 The detector 40 includes a first detector group 410 and a second detector group 420. The first detector group 410 is used to detect the first light information of the fill light component 20, and the second detector group 420 is used to detect the second light information of the display panel 10. The driving component 30 is electrically connected to the first detector group 410 and the second detector group 420, respectively, and is used to adjust the fill light information according to the first light information and the second light information.

[0033] For example, Figure 3In the illustrated embodiment, the detector 40 includes a first detector group 410 located on the fill light component 20 and a second detector group 420 located on the display panel 10. The first detector group 410 and the second detector group 420 each include a plurality of detectors, and the embodiment of the present invention does not limit the arrangement of the detectors in the first detector group 410 and the arrangement of the detectors in the second detector group 420. The first detector group 410 is used to detect the first light information of the fill light component 20, and the second detector group 420 is used to detect the second light information of the display panel 10. Then, the driving component 30 can adjust the fill light information of the fill light component 20 according to the comparison between the first light information detected by the first detector group 410 and the second light information detected by the second detector group 420. In this way, when adjusting the fill light information, the influence of the light output of the fill light component 20 itself is added, so that the fill light component 20 can be filled with light more accurately, further improving the dark line phenomenon of the display module in the seam area, and improving the display effect of the display module.

[0034] Optionally, based on the above embodiment, Figure 4 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Figure 2 and Figure 4 , the second detector group 420 includes a first sub-detector group 421 and a second sub-detector group 422. The two adjacent display panels 10 include a first display panel 101 and a second display panel 102. The first display panel 101 includes a first edge area A1 close to the fill light component 20, and the second display panel 102 includes a second edge area A2 close to the fill light component 20. The first sub-detector group 421 is located in the first edge area A1, and is used to detect the second A light output information of the first edge area A1. The second sub-detector group 422 is located in the second edge area A2, and is used to detect the second B light output information of the second edge area A2. The driving component 30 is used to adjust the fill light information according to the second A light output information, the second B light output information and the first light output information.

[0035] Specifically, Figure 2 and Figure 4As shown, the second detector group 420 includes a first sub-detector group 421 located in the first edge area A1, and a second sub-detector group 422 located in the second edge area A2. The first sub-detector group 421 is used to detect the second A light emitting information of the first edge area A1, and the second sub-detector group 422 is used to detect the second B light emitting information of the second edge area A2. Since the first edge area A1 is located in the area of ​​the first display panel 101 close to the fill light component 20, and the second edge area A2 is located in the area of ​​the second display panel 102 close to the fill light component 20, the second A light emitting information and the second B light emitting information are the light emitting information of the edges on both sides of the fill light component 20. Furthermore, by comparing the first light output information detected by the first detector group 410 with the second light output information A and the second light output information B respectively, the fill light information of the fill light component 20 can be adjusted according to the light output information at both side edges of the fill light component 20, so that the light output information of the seam area S1 and the first edge area A1 and the second edge area A2 are consistent, ensuring that the brightness and chromaticity of the seam area S1 do not change suddenly, thereby improving the display effect of the display module.

[0036] In one embodiment, see Figure 2 and Figure 4 The first sub-detector group 421 includes a plurality of first sub-detectors 4211, and the second sub-detector group 422 includes a plurality of second sub-detectors 4221. The first detector group 410 includes a plurality of first detectors 4101. The driving component 30 is used to adjust the fill light information according to the average value of a plurality of second A light output information detected by the plurality of first sub-detectors 4211, the average value of a plurality of second B light output information detected by the plurality of second sub-detectors 4221, and the average value of a plurality of first light output information detected by the plurality of first detectors 4101.

[0037] Specifically, in this embodiment, the extension direction of the seam area S1 is set as the second direction Y, the first direction X intersects with the second direction Y, and the first direction X and the second direction Y are parallel to the direction of the plane where the display panel 10 is located. The multiple first sub-detectors 4211 are used to detect the second A light information at different positions along the second direction Y in the first edge area A1, the multiple second sub-detectors 4221 are used to detect the second B light information at different positions along the second direction Y in the second edge area A2, and the multiple first detectors 4101 are used to detect the first light information at different positions on the fill light component along the second direction Y. It should be noted that the embodiment of the present invention does not limit the specific positions of the multiple first sub-detectors 4211 in the first edge area A1, the specific positions of the multiple second sub-detectors 4221 in the second edge area A2, and the specific positions of the multiple first detectors 4101 on the fill light component 20, and it is only necessary to satisfy that the multiple first sub-detectors 4211, the multiple second sub-detectors 4221, and the multiple first detectors 4101 are arranged along the second direction Y. After receiving the plurality of second A light emitting information and the plurality of second B light emitting information, the driving component 30 respectively determines the average value of the plurality of second A light emitting information and the average value of the plurality of second B light emitting information, thereby determining the first average light emitting information of the first edge area A1 and the second average light emitting information of the second edge area A2, and then adjusting the fill light information of the fill light component 20 according to the first average light emitting information, the second average light emitting information and the average value of the first light emitting information detected by the first detector 4101. Exemplarily, after determining the first average light emitting information of the first edge area A1 and the second average light emitting information of the second edge area A2, the comparison average value of the first average light emitting information and the second average light emitting information is obtained, and then the average value of the plurality of first light emitting information detected is compared with the comparison average value, if the average value of the plurality of first light emitting information is less than the comparison average value, then the brightness and / or chromaticity of the fill light component 20 is increased, if the average value of the plurality of first light emitting information is greater than the comparison average value, then the brightness and / or chromaticity of the fill light component 20 is reduced, and if the average value of the plurality of first light emitting information is equal to the comparison average value, then the brightness and / or chromaticity of the fill light component 20 is kept unchanged. In this way, the fill light information of the fill light component 20 is adjusted according to the average value of multiple second A light output information, the average value of multiple second B light output information and the average value of multiple first light output information, so that the light output information of the seam area S1 is made consistent with the first edge area A1 and the second edge area A2, and the brightness and chromaticity of the seam area S1 are ensured not to change suddenly, thereby making the fill light method of the fill light component 20 simple.

[0038] In yet another embodiment, Figure 5 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. Figure 2 and Figure 5, the first sub-detector group 421 includes a plurality of first sub-detectors 4211, and the second sub-detector group 422 includes a plurality of second sub-detectors 4221. The first detector group 421 includes a plurality of first detectors 4101. The first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 are correspondingly arranged. The driving component 30 is used to adjust the fill light information according to the average value of the second A light information detected by the correspondingly arranged first sub-detector 4211 and the second B light information detected by the second sub-detector 4221, and the first light information detected by the first detector 4101.

[0039] Specifically, Figure 2 and Figure 5 As shown, multiple first sub-detectors 4211, multiple second sub-detectors 4221, and multiple first detectors 4101 are arranged along the second direction Y. Multiple first sub-detectors 4211 are used to detect second A light information at different positions along the second direction Y in the first edge area A1, multiple second sub-detectors 4221 are used to detect second B light information at different positions along the second direction Y in the second edge area A2, and multiple first detectors 4101 are used to detect first light information at different positions along the second direction Y on the fill light component. In addition, the first detector 4101, the first sub-detectors 4211, and the second sub-detectors 4221 are correspondingly arranged. For example, Figure 5In the illustrated embodiment, the first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 are arranged in a one-to-one correspondence. The one-to-one correspondence can be understood as the first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 are all located in the same row along the first direction X. The first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 corresponding to the same row are respectively used to detect the first light emitting information, the second A light emitting information, and the second B light emitting information at the same position along the second direction Y. The driving component 30 compares the average value of the second A light emitting information and the second B light emitting information located in the same row with the first light emitting information of the same row, and adjusts the brightness and / or chromaticity of the first light emitting element 210 at the corresponding position in the fill light component 20 according to the comparison result. If the average value of the second A light emitting information and the second B light emitting information in the same row is greater than the first light emitting information, the brightness and / or chromaticity of the first light emitting element 210 at the corresponding position in the fill light component 20 is increased; if the average value of the second A light emitting information and the second B light emitting information in the same row is less than the first light emitting information, the brightness and / or chromaticity of the first light emitting element 210 at the corresponding position in the fill light component 20 is reduced; if the average value of the second A light emitting information and the second B light emitting information in the same row is equal to the first light emitting information, the brightness and / or chromaticity of the first light emitting element 210 at the corresponding position in the fill light component 20 is kept unchanged. On the basis of the above content, the fill light information at different positions in the fill light component 20 is adjusted according to the comparison of different rows. On the basis of making the light emitting information of the seam area S1, the first edge area A1 and the second edge area A2 tend to be consistent, and ensuring that the brightness and chromaticity of the seam area S1 do not change suddenly, fine adjustment of different positions on the fill light component 20 is achieved, further improving the display effect of the display panel.

That is, the first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 corresponding to the same row are respectively used to detect the first light emitting information of the first light emitting element group 2101, the second light emitting information of the second light emitting element group 50, and the second light emitting information of the third light emitting element group 60 at the same position along the second direction Y.

The first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 are arranged in one-to-one correspondence, and the first detector 4101 is also arranged in correspondence with the first light emitting element group 2101, the first sub-detector 4211 is also arranged in correspondence with the second light emitting element group 50, and the second sub-detector 4221 is also arranged in correspondence with the third light emitting element group 60. That is, the first detector 4101, the first sub-detector 4211, and the second sub-detector 4221 corresponding to the same row are respectively used to detect the first light emitting information of the first light emitting element group 2101, the second light emitting information of the second light emitting element group 50, and the second light emitting information of the third light emitting element group 60 at the same position along the second direction Y. The second light emitting element group 50 includes a second light emitting element row, and the third light emitting element group 60 includes a third light emitting element row. The first light emitting element group 2101 includes a first light emitting element row, that is, the fill light information of a first light emitting element row is adjusted by the second A light emitting information of a second light emitting element row and the second B light emitting information of a third light emitting element row, so as to further realize fine fill light at different positions on the fill light component 20 .

[0044] Optionally, based on the above embodiment, continue to refer to Figure 2 and Figure 7, the second light emitting element row includes a plurality of second light emitting elements 510, and the third light emitting element row includes a plurality of third light emitting elements 610. Along the first direction X, the second light emitting element 510 at least partially overlaps with the first light emitting element 210, and the third light emitting element 610 at least partially overlaps with the first light emitting element 210, wherein the first direction X intersects with the second direction Y, the second direction Y is the extension direction of the seam area S1, and the first direction X and the second direction Y are both parallel to the direction of the plane where the display panel 10 is located.

[0045] Specifically, on the one hand, Figure 7 As shown, along the first direction X, the second light-emitting element 510 at least partially overlaps with the first light-emitting element 210, and the third light-emitting element 610 at least partially overlaps with the first light-emitting element 210. It can be understood that when the fill light information of a first light-emitting element row is adjusted by the second A light-emitting information of a second light-emitting element row and the second B light-emitting information of a third light-emitting element row, a plurality of second light-emitting elements 510, a plurality of third light-emitting elements 610 and a plurality of first light-emitting elements 210 are located in the same row. In this way, on the basis of realizing fine fill light of the fill light component 20, it is ensured that the position of the fill light on the fill light component 20 corresponds to the position where the light information of the first display panel 101 and the second display panel 102 are detected, thereby further improving the fill light effect of the display module. On the other hand, as Figure 2 As shown, in the first direction X, the second light-emitting element 510 at least partially overlaps with the first light-emitting element 210, and the third light-emitting element 610 at least partially overlaps with the first light-emitting element 210. It can be understood that the first light-emitting element 210, the second light-emitting element 510 and the third light-emitting element 610 are approximately at the same height to ensure that the first light-emitting element 210, the second light-emitting element 510 and the third light-emitting element 610 emit light on the same horizontal plane.

[0046] Optionally, based on the above embodiment, Figure 8 yes Figure 3 A schematic cross-sectional view along the B-B' direction. Figure 3 and Figure 8 The driving assembly 30 includes a first driving assembly 310 and a second driving assembly 320. The second driving assembly 320 is electrically connected to the second detector group 420. The first driving assembly 310 is electrically connected to the second driving assembly 320, the first detector group 410 and the plurality of first light emitting elements 210, respectively.

[0047] Specifically, Figure 3 and Figure 8The driving component 30 includes a first driving component 310 disposed on the non-light emitting side of the fill light component 20 and a second driving component 320 disposed on the non-light emitting side of the display panel 10. The second driving component 320 is electrically connected to the second detector group 420 located on the light emitting side of the display panel 10, and then the second light emitting information of the display panel 10 is obtained through the second driving component 320. The first driving component 310 is electrically connected to the second driving component 320, the first detector group 410 and the plurality of first light emitting elements 210 respectively, and then the first driving component 310 can adjust the fill light information of the plurality of first light emitting elements 210 according to the second light emitting information obtained by the first driving component 320 and the first light emitting information detected by the first detector group 410. In this way, the light emitting information detected by the detector 40 is transmitted by indirect electrical connection of the plurality of driving components, avoiding the difficulty of wiring when all the detectors 40 are connected to one driving component.

[0048] Optionally, based on the above embodiment, continue to refer to Figure 7 , at least two display panels include a first display panel 101 and a second display panel 102. The first display panel 101 includes a plurality of second light-emitting elements 510, and the second display panel 102 includes a plurality of third light-emitting elements 610. The size of the second light-emitting elements 510 is larger than the size of the first light-emitting elements 210, and the spacing between two adjacent second light-emitting elements 510 is larger than the spacing between two adjacent first light-emitting elements 210. The size of the third light-emitting element 610 is larger than the size of the first light-emitting element 210, and the spacing between two adjacent third light-emitting elements 610 is larger than the spacing between two adjacent first light-emitting elements 210.

[0049] Specifically, since the fill light component 20 is disposed in the seam area S1 between the first display panel 101 and the second display panel 102, the space of the seam area S1 is relatively small, and when adjusting the chromaticity of the seam area S1, at least the first light-emitting element 210 including the red light-emitting element, the green light-emitting element and the blue light-emitting element needs to be set, therefore, in order to ensure that the seam area S1 can simultaneously accommodate the red light-emitting element, the green light-emitting element and the blue light-emitting element in the first direction X, the size of the first light-emitting element 210 needs to be set smaller than the size of the second light-emitting element 510 and the size of the third light-emitting element 610, and the spacing between two adjacent first light-emitting elements 210 is smaller than the size of two adjacent second light-emitting elements 510 and the size of two adjacent third light-emitting elements 610, so as to ensure that the fill light component 20 can perform chromaticity adjustment.

[0050] Optionally, based on the above embodiment, Fig. 9 yes Figure 1 Another cross-sectional structure schematic diagram along the A-A' direction. Fig. 9The fill light assembly 20 further includes a flexible substrate 220 and a support component 230. The flexible substrate 220 includes a driving circuit (not shown in the figure). The first light-emitting element 210 is disposed on the flexible substrate 220 and is electrically connected to the driving circuit. The support component 230 is located on a side of the flexible substrate 220 away from the first light-emitting element 210.

[0051] Specifically, the fill light assembly 20 also includes a flexible substrate 220. On the one hand, a driving circuit is provided on the flexible substrate 220, and the driving circuit is electrically connected to the first light-emitting element 210 to drive the first light-emitting element 210 to emit light. On the other hand, a flexible material is provided in the flexible substrate 220. When the flexible substrate 220 is provided between two adjacent display panels 10, the flexible substrate 220 can also isolate the direct physical contact between the two display panels 10, and play a buffering role. The supporting component 230 is located on the side of the flexible substrate 220 away from the first light-emitting element 210, and can support the flexible substrate 220. In addition, the height of the first light-emitting element 210 can also be adjusted through the supporting component 230, so that the height of the first light-emitting element 210 is close to the height of the light-emitting element in the display panel 10, thereby ensuring that the first light-emitting element 210 and the light-emitting element in the display panel 10 emit light at the same horizontal plane.

[0052] Optionally, based on the above embodiment, continue to refer to Fig. 9 , the fill light component 20 also includes a black encapsulation layer 240 and a transparent encapsulation layer 250. The first light-emitting element 210 is located in the black encapsulation layer 240, and the transparent encapsulation layer 250 is located on the light-emitting side of the first light-emitting element 210. Specifically, the black encapsulation layer 240 covers the entire flexible substrate 220, and then the black encapsulation layer 240 can absorb the reflected light reflected by the metal circuit layer in the flexible substrate 220. At the same time, the black encapsulation layer 240 also wraps the first light-emitting element 210, which can reduce the crosstalk of light between adjacent first light-emitting elements 210. In addition, the fill light component 20 also includes a transparent encapsulation layer 250 located on the side of the black encapsulation layer 240 away from the flexible substrate 220. The transparent encapsulation layer 250 can play a role in light extraction, thereby improving the light-emitting effect of the first light-emitting element 210.

[0053] Optionally, based on the above embodiment, Fig.10 yes Figure 1 Another cross-sectional structural diagram along the A-A' direction. Fig.10 The display module further includes a splicing bracket 70. The splicing bracket 70 is located at the backlight side of two adjacent display panels 10. The two adjacent display panels are spliced ​​together by the splicing bracket 70. Along the thickness direction of the display panel 10, the splicing area S1 at least partially overlaps with the splicing bracket 70.

[0054] Specifically, in the embodiment of the present invention, two adjacent display panels 10 can be spliced ​​by the splicing bracket 70, so as to ensure that the splicing method of the display module is simple and reliable. It should be noted that the embodiment of the present invention does not limit the specific splicing method of two adjacent display panels. In other embodiments, two adjacent display panels 10 can also be spliced ​​in other ways, and those skilled in the art can set it according to needs.
