[0029] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0030] It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the embodiments of the present invention may be combined with each other unless there is any contradiction.

[0031] Figure 1 A schematic structural diagram of a display module provided by an embodiment of the present invention is shown. Figure 2 for Figure 1 A structural diagram along the section line AA', refer to Figure 1 and Figure 2As shown, the display module 10 provided by the embodiment of the present invention includes a photosensitive area 100 and a non-photosensitive area 200 located at least on one side of the photosensitive area 100; the display module 10 also includes: a light-emitting element 300, located in the photosensitive area 100 and the non-photosensitive area 200; a light-shielding layer 400, located in the photosensitive area 100 and the non-photosensitive area 200 and located on the light-emitting side of the light-emitting element 300; a light-guiding layer 500, located at least in the photosensitive area 100 and on the side of the light-emitting element 300 away from the light-shielding layer 400; the light-guiding layer 500 includes a plurality of light-guiding openings 510, and the light-shielding layer 400 includes a plurality of first light-shielding openings 410 and a plurality of second light-shielding openings 420, the first light-shielding openings 410 are located in the photosensitive area 100, the second light-shielding openings 420 are located in the non-photosensitive area 200, and along the thickness direction h of the display module 10, the first light-shielding openings 410 and the light-guiding openings 510 at least partially overlap.

[0032] The display module 10 includes a photosensitive area 100 and a non-photosensitive area 200. The photosensitive area 100 can capture external light and perform optical recognition based on the captured light, such as fingerprint recognition or optical imaging, ensuring that the display module has optical recognition capabilities. The non-photosensitive area 200 is different from the photosensitive area and can be a normal display area that does not require external light.

[0033] Specifically, the display module 10 further includes a light-emitting element 300, a light-shielding layer 400, and a light-guiding layer 500. The light-shielding layer 400 is located on the light-emitting side of the light-emitting element 300, and the light-guiding layer 500 is located on the side of the light-emitting element 300 away from the light-shielding layer 400. That is, the light-shielding layer 400 and the light-guiding layer 500 are located on either side of the light-emitting element 300. Furthermore, the light-shielding layer 400 includes light-shielding distributions positioned between different light-emitting elements 300 in the photosensitive area 100 and the non-photosensitive area 200. The provision of the light-shielding layer 400 prevents crosstalk between light emitted by different light-emitting elements 300, thereby ensuring the display effect of the display module 10 in the photosensitive area 100 and the non-photosensitive area 200. The light-guiding layer 500 includes a plurality of light-guiding openings 510, which are provided at least in the photosensitive area 100. The light-guiding openings 510 are used to guide light into the photosensitive structure, ensuring that the photosensitive structure can achieve optical recognition based on the received light. For example, when the photosensitive structure is a fingerprint recognition structure, the optical guide opening 510 can be understood as an "imaging pinhole," and the fingerprint recognition structure implements fingerprint recognition based on the principle of pinhole imaging. Corresponding to the line guide opening 510 provided in the light guiding layer 500, a first light shielding opening 410 is provided in the light shielding layer 400. The first light shielding opening 410 is located in the photosensitive area 100, and along the thickness direction of the display module 10 (the h direction shown in the figure), the first light shielding opening 410 and the light guide opening 510 at least partially overlap, thereby ensuring that light passing through the first light shielding opening 410 can again enter the photosensitive structure through the light guide opening 510, ensuring that the photosensitive structure can perform optical recognition normally.

[0034] On this basis, the light-shielding layer 400 also includes a second light-shielding opening 420. The second light-shielding opening 420 is different from the first light-shielding opening 410. The second light-shielding opening 420 is arranged in the non-photosensitive area 420 and does not overlap with the light-guiding opening 510 in the light-guiding layer 500 along the thickness direction of the display module. That is, the second light-shielding opening 420 is not provided for receiving external light. Because the area of ​​the display module 10 where the light-shielding layer 400 is provided blocks the light emitted by the light-emitting element 300, the overall display is darker. The light at the first light-shielding opening 410 is brighter. Based on the regular arrangement of the first light-shielding opening 410 in the prior art, the display module 10 will exhibit fixed periodic dark-light stripes. The embodiment of the present invention provides the second light-shielding opening 420. The second light-shielding opening 420 is intended to break the regular arrangement of the first light-shielding opening 410, avoid the occurrence of fixed periodic dark-light stripes, and improve the display effect of the display module 10.

[0035] Furthermore, in the technical direction provided by the embodiment of the present invention, a third light-shielding opening 430 is further provided in the light-shielding layer 400. Along the thickness direction h of the display module 10, the third light-shielding opening 430 at least partially overlaps with the light-emitting element 300. The third light-shielding opening 430 is provided to ensure that the display light in the display module 10 is normally emitted, ensuring that the display module 10 normally emits light. It should be noted that the second light-shielding opening 420 in the light-shielding layer 400 in the embodiment of the present invention is a light-shielding opening that is different from the first light-shielding opening 410 and the third light-shielding opening 430. That is, the second light-shielding opening 420 is not provided to transmit optical recognition light and display light of the display module. The provision of the second light-shielding opening 420 is intended to break the regular arrangement of the first light-shielding opening 410, avoid the occurrence of fixed periodic dark and bright stripes, and improve the display effect of the display module 10.

[0036] Furthermore, the display module 10 provided in the embodiment of the present invention further includes a color filter layer 610 disposed in the third light-shielding opening 430 . The color filter layer 610 is used to reflect green light emitted by the light-emitting element 300 to achieve color display of the display module 10 . The display module 10 provided by the embodiment of the present invention is provided with a shading layer 400 and a color filter layer 610 on the light-emitting side of the light-emitting element 300. The shading layer 400 and the color filter layer 610 can not only ensure the color display of the display module 10 and avoid light crosstalk between adjacent light-emitting elements 300, but also replace the polarizer of the display module 10 by providing the shading layer 400 and the color filter layer 610. In this way, on the one hand, the reflection of external ambient light can be reduced by the shading layer 400 and the color filter layer 610, and the influence of external ambient light on the light output of the display module 10 can be reduced, thereby improving the display effect of the display module 10. On the other hand, by replacing the polarizer with the shading layer 400 and the color filter layer 610, the light output efficiency of the display module 10 can be improved. On the other hand, by replacing the polarizer with the shading layer 400 and the color filter layer 610, the display module 10 can be made bendable, which is conducive to realizing a bendable display module 10.

[0037] Exemplary, reference Figure 2 As shown, a thin-film encapsulation layer is further included between the light-shielding layer 400 and the light-emitting element 300 to enhance the encapsulation effect of the display module 10. Specifically, the thin-film encapsulation layer includes a first inorganic encapsulation layer 3613, a first organic encapsulation layer 3614, and a second inorganic encapsulation layer 3615. The embodiment of the present invention does not specifically limit the number of film layers included in the thin-film encapsulation layer. The light-shielding layer 400 and the color filter layer 610 can be disposed on the side of the thin-film encapsulation layer away from the light-emitting element, realizing a display module with a "CFOT" structure.

[0038] Optional, continue to refer to Figure 2As shown, the display module 10 provided by the embodiment of the present invention further includes a substrate 360. A pixel driving circuit 350 is further included in the film layer above the substrate 360. The pixel driving circuit 350 is electrically connected to the light-emitting element 300 and is used to drive the light-emitting element 300 to emit light, thereby achieving normal display of the display module 10. Specifically, the pixel driving circuit 350 includes alternately arranged insulating layers and metal layers, such as a first metal layer 361, a buffer layer 362, a gate insulating layer 336, an active layer 364, an intermetallic insulating layer 365, a second metal layer 366, an interlayer insulating layer 367, a capacitor plate layer 368, a third metal layer 369, a first insulating layer 3610, a first planarizing layer 3611, and a pixel definition layer 3612. Furthermore, the pixel driving circuit 350 includes a thin film transistor and a capacitor, and the display module 10 may include multiple pixel driving circuits 350. Specifically, the specific implementation of the pixel driving circuit 350 can be set by those skilled in the art according to actual conditions and is not limited here. For example, the pixel driving circuit includes "7T1C", "2T1C", etc., where "T" represents a thin film transistor and "C" represents a capacitor. Figure 2 As shown, the light-emitting element 300 includes an anode layer 310, a light-emitting layer 320 and a cathode layer 330. The pixel driving circuit 350 and the light-emitting element 300 are electrically connected through the fourth metal layer 340, that is, the light-emitting element 300 is driven to display light through the pixel driving circuit 350 to ensure the display effect of the photosensitive area 100 and the non-photosensitive area 200.

[0039] In summary, the display module provided by the embodiment of the present invention includes a photosensitive area and a non-photosensitive area, and the display module also includes a light-emitting element, a light-shielding layer, and a light-guiding layer. Among them, the light-shielding layer includes a plurality of first light-shielding openings and a plurality of second light-shielding openings, and the light-guiding layer includes a plurality of light-guiding openings. The plurality of first light-shielding openings and the light-guiding openings at least partially overlap to ensure that the display module collects light. At the same time, the light-shielding layer is additionally provided with a plurality of second light-shielding openings. The arrangement of the plurality of first light-shielding openings and the plurality of second light-shielding openings breaks the regularity of the arrangement of the light-shielding layer openings, avoids the occurrence of fixed periodic dark and light stripes, and improves the display effect of the display module.

[0040] For further reference, Figure 1 and Figure 2 As shown, along the thickness direction h of the display module 10 , the first light shielding opening 410 covers the light guiding opening 510 .

[0041] Specifically, the first light-shielding opening 410 covers the light-guiding opening 510, that is, the size of the first light-shielding opening 410 is larger than the size of the light-guiding opening 510, or in other words, the opening area of ​​the first light-shielding opening 410 is larger than the opening area of ​​the light-guiding opening 510, ensuring that the first light-shielding opening 410 does not block the light-guiding opening 510 from obtaining external light, that is, ensuring that optical recognition can be performed normally through the light-guiding opening 410.

[0042] Continue to refer Figure 1 and Figure 2 As shown, multiple light guiding openings 510 are arranged in an array; multiple first light shielding openings 410 are arranged in an array, and multiple second light shielding openings 420 are arranged in an array, and the distribution density of the first light shielding openings 410 is the same as the distribution density of the second light shielding openings 420.

[0043] Among them, the light guide openings 510 in the light guide layer 500 are arranged in an array to ensure that the external light obtained through the light guide openings 510 is balanced, for example, in the fingerprint recognition process, the imaging after the fingerprint is collected is uniform. Furthermore, the second light shielding openings 420 set in the light shielding layer 400 can break the regular arrangement of the first light shielding openings 410 in the light shielding layer 400, avoid the display module 10 from having fixed periodic dark and bright stripes, and improve the display effect of the display module 10. At the same time, the first light shielding openings 410 set in the photosensitive area 100A are combined with the second light shielding openings 420 set in the non-photosensitive area 200, that is, a uniform light shielding opening is set on the light-emitting side of the display module 10. This can weaken the local display imbalance in the display module 10 and improve the overall uniformity of the display module 10.

[0044] For example, if the fingerprint recognition process is realized through the light guiding opening 510, the first light shielding opening 410 and the second light shielding opening 420 are evenly arranged on the front, which can weaken the display unevenness of the photosensitive area 100, i.e., the fingerprint recognition area, and improve the overall display effect of the display module 10.

[0045] Figure 3 A schematic structural diagram of another display module provided by an embodiment of the present invention, Figure 4 A schematic structural diagram of another display module provided by an embodiment of the present invention, Figure 5 A schematic diagram of another display module provided by an embodiment of the present invention, referring to Figures 3 to 5 As shown, along the direction from the photosensitive area 100 to the non-photosensitive area 200 , the sum of the opening areas of the second light shielding openings 420 decreases gradually within a unit area.

[0046] Specifically, such as Figures 3 to 5As shown, along the direction from the photosensitive area 100 to the non-photosensitive area 200, that is, with the photosensitive area 100 as the center and in the direction extending toward the surrounding non-photosensitive areas 200, the sum of the opening areas of the second light-shielding openings 420 arranged in the non-photosensitive area 200 within a unit area gradually decreases, that is, within a unit area, the sum of the opening areas of the second light-shielding openings 420 close to the photosensitive area 10 side is greater than the sum of the opening areas of the second light-shielding openings 420 away from the photosensitive area 10 side.

[0047] Specifically, by providing the second light-shielding openings 420 to disrupt the regular arrangement of the openings in the light-shielding layer 400, the display module 10 is prevented from exhibiting fixed-periodic dark-light fringes, thereby improving the display quality of the display module 10. At the same time, along the direction from the photosensitive region 100 toward the non-photosensitive region 200, the sum of the opening areas of the second light-shielding openings 420 per unit area gradually decreases. This ensures that along the direction from the photosensitive region 100 toward the non-photosensitive region 200, the sum of the opening areas of the light-shielding openings in the light-shielding layer 400 per unit area gradually changes. This weakens the dark-light fringes caused by the openings in the light-shielding layer, avoids exacerbating the dark-light fringes phenomenon due to a sudden change in the sum of the opening areas of the light-shielding openings, and thereby improves the display quality of the display module 10.

[0048] Furthermore, within a unit area, the sum of the opening areas of the second light-shielding openings 420 can be smaller than the sum of the opening areas of the first light-shielding openings 420. This can ensure that the photosensitive area 100 receives sufficient light, thereby ensuring the accuracy and sensitivity of optical recognition. On the other hand, it can ensure that the sum of the opening areas of the light-shielding openings in the non-photosensitive area 200 is smaller, thereby reducing the light entering the display module 10 through the second light-shielding openings 420, thereby reducing the light emitted after reflection from the display module 10, reducing the influence of external ambient light on the normal display of the display module 10, and improving the display contrast of the display module 10.

[0049] Continue to refer Figure 3 and Figure 5 As shown, along the direction from the photosensitive area 100 to the non-photosensitive area 200 , the distribution density of the second light shielding openings 420 gradually decreases.

[0050] Specifically, when the sum of the opening areas of the second light shielding openings 420 away from the first light shielding openings 410 is smaller than the sum of the opening areas of the second light shielding openings 420 close to the first light shielding openings 410, the overall display effect of the display module 10 can be improved. This can be achieved by adjusting the distribution density of the second light shielding openings 420 at different positions. Figure 3 and Figure 5As shown, the distribution density of the second light-shielding openings 420 near the photosensitive area 100 is greater than the distribution density of the second light-shielding openings 420 away from the photosensitive area 100. That is, by adjusting the distribution density of the second light-shielding openings 420, the sum of the opening areas of the second light-shielding openings 420 per unit area is adjusted, thereby weakening the dark-light stripes caused by the openings in the light-shielding layer 400, avoiding the dark-light stripes phenomenon caused by a sudden change in the sum of the opening areas of the light-shielding openings, and improving the display effect of the display module 10.

[0051] It can be understood that the distribution density of the second light shielding openings 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. It can be set that the non-photosensitive area 200 includes multiple sub-non-photosensitive areas along the direction from the photosensitive area 100 to the non-photosensitive area 200, and the distribution density of the second light shielding openings 420 in different sub-non-photosensitive areas gradually decreases. The distribution density of the two light shielding openings 420 in the same sub-non-photosensitive area is the same, such as Figure 3 and Figure 5 As shown, in this way, the distribution density of the second light-shielding openings 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. Alternatively, the distribution density of the second light-shielding openings 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. It can be set that along the direction from the photosensitive area 100 to the non-photosensitive area 200, the non-photosensitive area 200 includes multiple sub-non-photosensitive areas, the distribution density of the second light-shielding openings 420 in different sub-non-photosensitive areas gradually decreases, and the distribution density of the two light-shielding openings 420 in the same sub-non-photosensitive area also gradually decreases (not shown in the figure), so that the distribution density of the second light-shielding openings 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. The embodiment of the present invention does not limit the technical solution for how to achieve the gradual decrease in the distribution density of the second light-shielding openings 420 along the direction from the photosensitive area 100 to the non-photosensitive area 200.

[0052] Continue to refer Figure 4 and Figure 5 As shown, along the direction from the photosensitive area 100 to the non-photosensitive area 200 , the opening area of ​​the second light shielding opening 420 gradually decreases.

[0053] Specifically, when the sum of the opening areas of the second light shielding openings 420 away from the first light shielding openings 410 is smaller than the sum of the opening areas of the second light shielding openings 420 close to the first light shielding openings 410, the overall display effect of the display module 10 can be improved. This can be achieved by adjusting the opening areas of the second light shielding openings 420 at different positions. Figure 4 and Figure 5As shown, the opening area of ​​the second light shielding opening 420 near the photosensitive area 100 is larger than the opening area of ​​the second light shielding opening 420 away from the photosensitive area 100. That is, by adjusting the opening area of ​​the second light shielding opening 420, the sum of the opening areas of the second light shielding openings 420 is adjusted, thereby weakening the dark-light stripes caused by the openings in the light shielding layer 400, avoiding the dark-light stripes phenomenon caused by a sudden change in the sum of the opening areas of the light shielding openings, and improving the display effect of the display module 10.

[0054] It can be understood that, along the direction from the photosensitive area 100 to the non-photosensitive area 200, the opening area of ​​the second light shielding opening 420 gradually decreases. It can be set that along the direction from the photosensitive area 100 to the non-photosensitive area 200, the non-photosensitive area 200 includes multiple sub-non-photosensitive areas, and the opening area of ​​the second light shielding opening 420 in different sub-non-photosensitive areas gradually decreases. The opening area of ​​the two light shielding openings 420 in the same sub-non-photosensitive area is the same, such as Figure 4 and Figure 5 As shown, in this way, the opening area of ​​the second light-shielding opening 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. Alternatively, the opening area of ​​the second light-shielding opening 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. It can be set that along the direction from the photosensitive area 100 to the non-photosensitive area 200, the non-photosensitive area 200 includes multiple sub-non-photosensitive areas, the opening areas of the second light-shielding opening 420 in different sub-non-photosensitive areas gradually decrease, and the opening areas of the two light-shielding openings 420 in the same sub-non-photosensitive area also gradually decrease, so that the opening area of ​​the second light-shielding opening 420 gradually decreases along the direction from the photosensitive area 100 to the non-photosensitive area 200. The embodiment of the present invention does not limit the technical solution for how to achieve the gradual decrease in the opening area of ​​the second light-shielding opening 420 along the direction from the photosensitive area 100 to the non-photosensitive area 200.

[0055] For further reference, Figure 5 As shown, along the direction from the photosensitive area 100 to the non-photosensitive area 200, the sum of the opening areas of the second light-shielding openings 420 within a unit area gradually decreases. The opening area of ​​the second light-shielding openings 420 close to the photosensitive area 100 can also be set to be larger than the opening area of ​​the second light-shielding openings 420 away from the photosensitive area 100. At the same time, the distribution density of the second light-shielding openings 420 close to the photosensitive area 100 is greater than the distribution density of the second light-shielding openings 420 away from the photosensitive area 100. In this way, the sum of the opening areas can be adjusted by adjusting the opening area and the distribution density of the second light-shielding openings 420, ensuring that the dark and light lines caused by the openings in the light-shielding layer 400 are weakened by the gradual change of the sum of the openings, avoiding the dark and light line phenomenon caused by the sudden change of the sum of the opening areas of the light-shielding openings, and improving the display effect of the display module 10.

[0056] The above embodiment provides a detailed description of the setting method of the first light-shielding opening and the second light-shielding opening. On this basis, the dark and light lines caused by the openings in the light-shielding layer can be weakened by adjusting the setting method of the first light-shielding opening and the light-guiding opening. The specific description is given below.

[0057] As a feasible implementation method, Figure 6 for Figure 1 An enlarged schematic diagram of area B, see Figure 1 、 Figure 2 and Figure 6 As shown, the light guiding layer 500 includes a first light guiding opening 510A and a second light guiding opening 510B, the first light guiding opening 510A includes a first opening center 510A1, and the second light guiding opening 510B includes a second opening center 510B1; the first light shielding opening 410 includes a first sub-light shielding opening 410A and a second sub-light shielding opening 410B, the first sub-light shielding opening 410A includes a third opening center 410A1, and the second sub-light shielding opening 410B includes a fourth opening center 410B1, along the thickness direction h of the display module 10, the first sub-light shielding opening 410A at least partially overlaps with the first light guiding opening 510A, and the second sub-light shielding opening 410B at least partially overlaps with the second light guiding opening 510B; the first opening center 510A1 and the third opening center 410A1 have a first relative position relationship, the second opening center 510B1 and the fourth opening center 410B1 have a second relative position relationship, and the first relative position is different from the second relative position relationship.

[0058] Specifically, the light guiding layer 500 includes a first light guiding opening 510A and a second light guiding opening 510B, and the first light shielding opening 410 includes a first sub-light shielding opening 410A and a second sub-light shielding opening 410B. The first sub-light shielding opening 410A at least partially overlaps with the first light guiding opening 510A, that is, the first light guiding opening 510A obtains external light through the first sub-light shielding opening 410A, and the second sub-light shielding opening 410B at least partially overlaps with the second light guiding opening 510B, that is, the second light guiding opening 510B obtains external light through the second sub-light shielding opening 410B.

[0059] Furthermore, the first light guiding opening 510A includes a first opening center 510A1, the second light guiding opening 510B includes a second opening center 510B1, the first sub-light shielding opening 410A includes a third opening center 410A1, the second sub-light shielding opening 410B includes a fourth opening center 410B1, the first opening center 510A1 and the third opening center 410A1 have a first relative position relationship, the second opening center 510B1 and the fourth opening center 410B1 have a second relative position relationship, and the first relative position is different from the second relative position relationship. The different relative position relationship can be understood as the setting position of the first opening center 510A1 relative to the third opening center 410A1 is different from the setting position of the second opening center 510B1 relative to the fourth opening center 410B1. Figure 6 As shown in the example, along the thickness direction h of the display module 10, the first opening center 510A1 is staggered from the third opening center 410A1, and the first opening center 510A1 is located to the left of the third opening center 410A1. The second opening center 510B1 is staggered from the fourth opening center 410B1, and the second opening center 510B1 is located to the right of the fourth opening center 410B1. By setting the first opening center 510A1 at a different position relative to the third opening center 410A1 than the second opening center 510B1 at a different position relative to the fourth opening center 410B1, the regular arrangement of the openings in the light shielding layer 400 and the light guiding layer in the photosensitive area 100 is broken, and the periodic dark and bright fringes in the display module 10 caused by the periodic openings in the light shielding layer 400 are effectively reduced, thereby improving the overall display effect of the display module 10.

[0060] It should be noted that Figure 6In the figure, only the example in which the first opening center 510A1 and the third opening center 410A1 are staggered and the first opening center 510A1 is set on the left side of the third opening center 410A1, and the second opening center 510B1 and the fourth opening center 410B1 are staggered and the second opening center 510B1 is set on the right side of the fourth opening center 410B1 is used for illustration rather than limitation by lines. It can be understood that the relative position relationship between the first opening center 510A1 and the third opening center 410A1, and the relative position relationship between the second opening center 510B1 and the fourth opening center 410B1, can be arranged in other ways. For example, the first opening center 510A1 may coincide with the third opening center 410A1, and the second opening center 510B1 may be staggered with the fourth opening center 410B1; the first opening center 510A1 may be staggered with the third opening center 410A1 and the first opening center 510A1 may be set below the third opening center 410A1, the second opening center 510B1 may be staggered with the fourth opening center 410B1 and the second opening center 510B1 may be set above the fourth opening center 410B1; the first opening center 510A1 may be staggered with the third opening center 410A1 and the first opening center 510A1 may be set on the upper left side of the third opening center 410A1, the second opening center 510B1 may be staggered with the fourth opening center 410B1 and the second opening center 510B1 may be set on the upper right side of the fourth opening center 410B1, and so on. They will not be listed one by one here.

[0061] It should also be noted that the first light guiding opening 510A and the second light guiding opening 510B can be any two light guiding openings 510 in the light guiding layer 500, and the first sub-light shielding opening 410A and the second sub-light shielding opening 410B can be any two light shielding openings in the first light shielding opening 410, that is, the centers of any two light guiding openings and the centers of the corresponding sub-light shielding openings have different relative position relationships, that is, there is no situation in the photosensitive area 100 where the relative position relationship between the center of the light guiding opening and the center of the sub-light shielding opening is the same, thereby fully reducing the periodic dark and light stripes of the display module 10 caused by the periodic openings of the light shielding layer 400, thereby improving the overall display effect of the display module 10. Alternatively, there is a situation in which the relative position relationship between the center of the light guiding opening and the center of the sub-light-shielding opening is the same in the photosensitive area 100, and there is also a situation in which the relative position relationship between the center of the light guiding opening and the center of the sub-light-shielding opening is different. In this way, on the basis of ensuring that the periodic dark and light stripes caused by the periodic opening of the light-shielding layer 400 in the weak display module 10 are eliminated, the relative position relationship requirements between the center of the light guiding opening and the center of the sub-light-shielding opening can be reduced, thereby reducing the difficulty of the preparation process of the display module 10.

[0062] As another possible implementation, Figure 7 for Figure 1 Another enlarged schematic diagram of area B in the middle, Figure 8 for Figure 1 Another enlarged schematic diagram of area B, see Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the light guiding layer 500 includes a third light guiding opening 510C and a fourth light guiding opening 510D; the first light shielding opening 410 includes a third sub-light shielding opening 410C and a fourth sub-light shielding opening 410D. Along the thickness direction h of the display module 10, the third sub-light shielding opening 410C at least partially overlaps with the third light guiding opening 510C, and the fourth sub-light shielding opening 410D at least partially overlaps with the fourth light guiding opening 510D; the opening areas of the third sub-light shielding opening 410C and the fourth sub-light shielding opening 410D are different.

[0063] Specifically, the third sub-light-shielding opening 410C at least partially overlaps with the third light-guiding opening 510C, that is, the third light-guiding opening 510C obtains external light through the third sub-light-shielding opening 410C, and the fourth sub-light-shielding opening 410D at least partially overlaps with the fourth light-guiding opening 510D, that is, the fourth light-guiding opening 510D obtains external light through the fourth sub-light-shielding opening 410D.

[0064] For further reference, Figure 7 As shown, the opening area of ​​the third sub-light-shielding opening 410C is different from that of the fourth sub-light-shielding opening 410D, that is, by adjusting the opening area of ​​the first light-shielding opening 410 in the photosensitive area 100 to different sizes at different positions, the regularity of the opening setting of the light-shielding layer 400 can be further broken, and the periodic dark and light lines of the display module 10 caused by the periodic opening of the light-shielding layer 400 can be better reduced, thereby improving the overall display effect of the display module 10.

[0065] It should also be noted that the third sub-light-shielding opening 410C and the fourth sub-light-shielding opening 410D can be any two light-shielding openings in the first light-shielding opening 410. That is, the opening areas of any two sub-light-shielding openings in the first light-shielding opening 410 are different. This effectively reduces the periodic dark-light fringes in the display module 10 caused by the periodic openings of the light-shielding layer 400, thereby improving the overall display effect of the display module 10. Alternatively, the opening areas of the sub-light-shielding openings in the first light-shielding opening 410 may be the same, or the opening areas of the sub-light-shielding openings may be different. In this way, while ensuring that the periodic dark-light fringes in the display module 10 caused by the periodic openings of the light-shielding layer 400 are reduced, the opening size requirements of the sub-light-shielding openings in the first light-shielding opening 410 can be reduced, thereby reducing the difficulty of the manufacturing process of the display module 10.

[0066] For further reference, Figure 8 As shown, the third light guiding opening 510C includes a fifth opening center 510C1, the fourth light guiding opening 510D includes a sixth opening center 510D1, the third sub-light shielding opening 410C includes a seventh opening center 410C1, and the fourth sub-light shielding opening 410D includes an eighth opening center 410D1. The fifth opening center 510C1 and the seventh opening center 410C1 have a third relative positional relationship, and the sixth opening center 510D1 and the eighth opening center 410D1 have a fourth relative positional relationship, with the third relative position being different from the fourth relative positional relationship. In other words, while the opening area of ​​the first light shielding opening 410 in the photosensitive region 100 can be adjusted to different sizes at different locations, the center of the light guiding opening and the center of the first light shielding opening in the photosensitive region 100 can also be staggered, further disrupting the regularity of the opening arrangement of the light shielding layer 400 and improving the overall display effect of the display module 10.

[0067] refer to Figures 1 to 8 As shown, a plurality of light guiding openings 510 are arranged in an array.

[0068] Specifically, by arranging the light guide openings 510 in the photosensitive area 100 in an array, it is possible to ensure that different areas of the photosensitive area 100 receive the same light, ensuring consistent optical recognition effects in different areas of the photosensitive area 100, and improving the balance of optical recognition. For example, the photosensitive area 100 may be a fingerprint recognition area. By arranging the light guide openings 510 in an array in the fingerprint preparation area, it is possible to ensure a balanced fingerprint recognition effect in different areas of the fingerprint recognition area, thereby improving the accuracy of fingerprint recognition.

[0069] The above embodiment can weaken the dark-light stripes caused by the openings in the light-shielding layer by adjusting the arrangement of the first light-shielding opening and the light-guiding opening, thereby improving the display effect of the display module.

[0070] Based on the above embodiments, Figure 9 for Figure 1 Another structural diagram along the section line AA', refer to Figure 9 As shown, the display module 10 further includes a reflection adjustment unit 600 ; the reflection adjustment unit 600 fills the first light shielding opening 410 and the second light shielding opening 420 .

[0071] Specifically, by providing a second light-shielding opening 420 in the light-shielding layer 400, the regular arrangement of the light-shielding openings in the light-shielding layer 400 is broken, thereby preventing the display module 10 from having fixed periodic dark and bright stripes, thereby improving the display effect of the display module 10. However, since multiple second light-shielding openings 420 are added on the basis of the original light-shielding openings in the light-shielding layer 400, more external light will enter the display module 10 through the light-shielding openings in the light-shielding layer 400. Moreover, the external ambient light will affect the normal display of the display module 10 after being reflected by the reflective layer (such as metal wiring) in the display module 10, thereby interfering with the normal display of the display module 10. Therefore, in an embodiment of the present invention, a reflection adjustment unit 600 is creatively filled in the first light-shielding opening 410 and the second light-shielding opening 420 of the light-shielding layer 400. The reflection adjustment unit 600 adjusts the ambient light entering the display module 10 and the ambient light reflected to the outside by the reflection adjustment unit 600, thereby reducing the interference of the external ambient light on the display and improving the display effect of the display module 10.

[0072] Continue to refer Figure 9 As shown, the display module 10 further includes a color filter layer 610 located on the light-emitting side of the light-emitting element 300 ; the reflection adjustment unit 600 reuses the color filter layer 610 .

[0073] Specifically, the display module 10 further includes a color filter layer 610, which may include a red light filter layer, a green light filter layer, and a blue light filter layer. The color filter layers 610 of different colors correspond to light-emitting elements 300 of different colors. Figure 10 In the following, the color filter layer 610 includes a green color filter layer 610G and a red color filter layer 610R. The green color filter layer 610G corresponds to the green light-emitting element 300G, and the red color filter layer 610R corresponds to the red light-emitting element 300R. The color filter layer 610 corresponding to the light-emitting element 300 is placed at the third light-shielding opening 430 of the light-shielding layer 400. The color filter layer 610 can improve the purity of the light emitted by the light-emitting element 300 and filter external light, that is, reduce the external ambient light entering the display module 10. It can further filter the external ambient light emitted by the display module 10, reduce the emission of external ambient light, and further improve the light output effect of the display module 10.

[0074] As described above, since the color filter layer 610 can filter external light and further filter the ambient light emitted by the display module 10, thereby reducing the emission of the ambient light, the color filter layer 610 and the reflection adjustment layer 600 have the same function, and thus the color filter layer 610 can be reused as the reflection adjustment unit 600. That is, the color filter layer 610 is provided at both the first light-shielding opening 410 and the second light-shielding opening 420 of the light-shielding layer 400, thereby ensuring an improved overall display effect of the display module 10, simplifying the manufacturing process of the display module 10, and improving the manufacturing efficiency of the display module 10.

[0075] Further, Figure 10 for Figure 1 Another structural diagram along the section line AA', refer to Figure 10 As shown, the color filter layer 610 includes a green color filter layer 610G; the green color filter layer 610G fills the first light shielding opening 410 .

[0076] Specifically, the green light filter layer 610G fills the first light shielding opening 410, and the green light is incident on the photosensitive structure through the first light shielding opening 410 and the corresponding light guiding opening, ensuring that the photosensitive structure can perform optical recognition based on the acquired green light. Since the optical recognition process is more sensitive to green light, setting a green light filter layer 610G to fill the first light shielding opening 410 can improve the sensitivity of optical recognition and improve the accuracy of optical recognition. For example, if the photosensitive area 100 is a fingerprint recognition area, the light guiding opening 510 is an imaging pinhole for fingerprint recognition, and the fingerprint recognition sensor corresponding to the light guiding opening 510 (not shown in the figure) is more sensitive to green light, that is, filling the first light shielding opening 410 with a green light filter layer 610G can improve the sensitivity and accuracy of the fingerprint recognition process.

[0077] Further, Figure 11 for Figure 1 Another structural diagram along the section line AA', refer to Figure 11 As shown, the color filter layer 610 includes a red color filter layer 610R; the red color filter layer 610R fills the second light shielding opening 420 .

[0078] Specifically, compared with the color filter layers of other colors, the red light filter layer 610R has the lowest reflectivity. When the second light-shielding opening 420 is filled with the red light filter layer 610R, the reflectivity of the external ambient light at the red light filter layer 610R can be reduced, thereby reducing the interference of the external ambient light on the display module 10 and improving the display effect.

[0079] Further, Figure 12 for Figure 1 Another structural diagram along the section line AA', refer to Figure 12 As shown, the green light filter layer 610G can also be filled in the first light shielding opening 410, and the red light filter layer 610R can be filled in the second light shielding opening 420. In this way, the advantages of the green light filter layer 610G and the red light filter layer 610R can be combined. On the one hand, the sensitivity of optical recognition can be improved and the accuracy of optical recognition can be improved. On the other hand, the reflectivity of external ambient light at the red light filter layer 610R can be reduced, thereby reducing the interference of external ambient light on the display module 10 and improving the display effect.

[0080] Based on the above embodiments, Figure 13 for Figure 1 Another structural diagram along the section line AA', Figure 14 for Figure 1 Another structural diagram along the section line AA', Figure 15 for Figure 1 Another structural diagram along the section line AA', refer to Figures 13 and 14 As shown, the display module 10 also includes a display panel 700 and a photosensitive layer 800; the photosensitive layer 800 is arranged on the non-light-emitting side of the display panel 700, and the light guiding layer 500 is arranged between the photosensitive layer 800 and the display panel 700; or, the photosensitive layer 800 is arranged on the non-light-emitting side of the display panel 700, and the light guiding layer 500 is arranged in the display panel 700; or, both the photosensitive layer 800 and the light guiding layer 500 are arranged in the display panel 700.

[0081] The display module 10 includes a display panel 700 and a photosensitive layer 800. The display panel 700 includes a substrate 360 ​​and a film structure above. This embodiment of the present invention does not specifically limit this. The photosensitive layer 800 can be an optical recognition structure for acquiring light. Exemplarily, the photosensitive area 100 of the display module 10 is a fingerprint recognition area, and the photosensitive layer 800 can be a plurality of fingerprint recognition units for performing fingerprint recognition based on the light transmitted by the light guide opening 510. This embodiment of the present invention does not specifically limit this.

[0082] Furthermore, the photosensitive layer 800 and the display panel 700 may include a variety of configurations, for example, referring to Figure 13 As shown, the photosensitive layer 800 and the light guiding layer 500 are both arranged on the non-light-exiting side of the display panel 700, that is, arranged outside the display panel 700, and the light guiding layer 500 is placed between the photosensitive layer 800 and the display panel 700. In this way, the display panel 700, the light guiding layer 500 and the photosensitive layer 800 are all independently arranged, and the display panel 700, the light guiding layer 500 and the photosensitive layer 800 have a high degree of freedom in setting and flexible adjustment methods. Figure 14 As shown, the photosensitive layer 800 is placed outside the display panel, while the light guiding layer 500 is placed inside the display panel 700. In this way, the light guiding layer 500 can reuse some film layers in the display panel 700, and the arrangement of the light guiding layer 500 is simple. In addition, the display panel 700 and the photosensitive layer 800 are independently arranged, and the arrangement of the display panel 700 and the photosensitive layer 800 is high in freedom and flexible in adjustment. Figure 15 As shown, the photosensitive layer 800 and the light guiding layer 500 are both placed inside the display panel 700, so that the light guiding layer 500 can reuse certain film layers in the display panel 700, and the setting method of the light guiding layer 500 is simple; at the same time, the display module 10 has a high degree of integration, which is conducive to realizing a thin design of the display module 10.

[0083] It should be noted that the embodiments of the present invention do not impose any specific restrictions on the specific locations of the light guide layer and the photosensitive layer. The locations of the light guide layer and the photosensitive layer can be flexibly adjusted according to actual needs to meet various usage requirements.

[0084] Based on the above embodiments, Figure 16 for Figure 1 Another structural diagram along the section line AA', refer to Figure 2 and Figure 16 As shown, the light guiding layer 500 is arranged in the display panel 700; the display panel 700 includes a substrate 360 ​​and a first metal layer 361, a second metal layer 366, a capacitor plate layer 368, a third metal layer 369 and a fourth metal layer 340 located on one side of the substrate 360 ​​in sequence; the light guiding layer 500 reuses the first metal layer 361, the second metal layer 366, the capacitor plate layer 368, the third metal layer 369 or the fourth metal layer 340.

[0085] Specifically, the light guiding layer 500 is not positioned in a fixed location and can be positioned in different film layers. For example, the light guiding layer 500 can be reused as the first metal layer 361, the second metal layer 366, the capacitor plate layer 368, the third metal layer 369, or the fourth metal layer 340 in the display panel 700. The specific configuration can be based on actual needs. The light guiding layer 500 is reused as one metal layer in the display panel 700. The light guiding openings in the light guiding layer 500 can be fabricated during the patterning process of the metal layer. This ensures that the light guiding layer and the optical guiding openings are easily implemented, and that the film structure of the display module 10 is simple, which facilitates a thin design of the display module 10.

[0086] For example, continue to refer to Figure 2 As shown, the light guide layer 500 is reused as the first metal layer 361 in the display panel 700. The first metal layer 361 can be a metal layer between the film layer where the pixel driving circuit 350 is located and the film layer where the substrate 360 ​​is located in the display panel. The first metal layer can block external ambient light from entering the pixel driving circuit 350, for example, blocking external ambient light from entering the channel of the active layer 364, thereby avoiding light leakage in the channel due to illumination, and ensuring that the normal display of the display panel is not disturbed. For example, continue to refer to Figure 16As shown, the light guiding layer 500 is reused as the fourth metal layer 340 in the display panel 700. The fourth metal layer 340 can be a metal layer between the film layer where the pixel driving circuit 350 is located and the film layer where the light-emitting element 300 is located. The fourth metal layer 340 can serve as a bridging layer between the pixel driving circuit 350 and the light-emitting element 300. In this way, when the light-emitting element 300 is electrically connected to the pixel driving circuit 350, a deep drilling process can be avoided, thereby ensuring that the electrical connection process between the light-emitting element 300 and the pixel driving circuit 350 is simple.
