Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display module and a display device. Background Art

[0002] Most of the existing display devices are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light and needs to rely on the light source provided by the backlight module to display images normally, the backlight module has become one of the key components of the liquid crystal display device.

[0003] Generally, a high light transmittance area is set in the display area of the display panel to accommodate photosensitive elements. The high light transmittance area is usually a through hole formed after the backlight module is perforated. However, during the display process, there will be phenomena such as black areas in the photosensitive elements or light leakage of the light guide plate, which seriously affect the display effect of the display panel. Summary of the Invention

[0004] The present invention provides a display module and a display device, which can achieve supplementary lighting for the light collection area and ensure the display effect of the display panel.

[0005] According to one aspect of the present invention, a display module is provided, including:

[0006] A display panel;

[0011] A first light adjustment structure located between the backlight module and the display panel, along the thickness direction of the display module, at least part of the first light adjustment structure overlaps with the light collection area.

[0012] According to another aspect of the present invention, a display device is provided, including the display module according to any one of the above aspects.

[0013] The technical solution of the embodiment of the present invention is realized through a display module, which includes: a display panel; a backlight module located on the light-emitting surface side away from the display panel; the backlight module includes a light-collecting area and a light-emitting area surrounding the light-collecting area; a through hole is provided in the light-collecting area, and the through hole penetrates the backlight module; a light-collecting element, along the thickness direction of the display module, at least part of the through hole overlaps with the light-collecting element; the backlight module includes a substrate and micro light-emitting elements located on one side of the substrate and in the light-emitting area, and adjacent micro light-emitting elements are arranged at intervals; a first light adjustment structure is located between the backlight module and the display panel, and along the thickness direction of the display module, the first light adjustment structure at least partially overlaps with the light-collecting area. By providing the first light adjustment structure between the backlight module and the display panel, the light emitted by the micro light-emitting elements converges in the positive projection direction of the light-collecting area, thereby ensuring the supplementary light for the light-collecting area and ensuring the overall display effect of the display module.

[0041] Figure 1 It is a schematic structural diagram of a display module provided by an embodiment of the present invention. Figure 2 It is a schematic structural diagram of another display module provided by an embodiment of the present invention. Figure 3 It is a schematic structural diagram of another display module provided by an embodiment of the present invention. Figure 4 It is a schematic structural diagram of another display module provided by an embodiment of the present invention, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. The display module 100 includes: a display panel 101; a backlight module 102 located on the light-emitting surface side away from the display panel 101; the backlight module 102 includes a light-gathering area 103 and a light-emitting area 104 surrounding the light-gathering area 103; a through hole 105 is provided in the light-gathering area 103, and the through hole 105 penetrates the backlight module 102; a light-gathering element 106, along the thickness direction Y of the display module 100, the through hole 105 at least partially overlaps with the light-gathering element 106; the backlight module 102 includes a substrate 1021 and micro light-emitting elements 107 located on one side of the substrate 1021 and in the light-emitting area 104, and adjacent micro light-emitting elements 107 are arranged at intervals; a first light adjustment structure 108 is located between the backlight module 102 and the display panel 101, and along the thickness direction Y of the display module 100, the first light adjustment structure 108 at least partially overlaps with the light-gathering area 103.

[0042] Among them, the backlight module 102 is used to provide light source for the display panel 101 to ensure the normal display of the display panel 101. The backlight module 102 includes a light collection area 103 and a light output area 104 surrounding the light collection area 103. The light collection area 103 includes a through hole 105 penetrating the backlight module 102. The display module 100 further includes a light collection element 106. The light collection element 106 can be a device such as a camera or a sensor to achieve full-screen display. Along the thickness direction Y of the display module 100, the through hole 105 and the light collection element 106 at least partially overlap, so that external light can pass through the display panel 101 and the through hole 105 and be incident on the light collection element 106, thereby realizing the photographing function of the display module 100. As Figure 1 shown, the light collection element 106 can be integrally arranged on the side of the backlight module 102 away from the display panel 101; as Figure 2 shown, only a part of the light collection element 106 is embedded in the through hole 105, and the other part is located on the side of the backlight module 102 away from the display panel 101; or, as Figure 3 shown, in order to further reduce the thickness of the display module 100, the light collection element 106 can be integrally embedded in the through hole 105. The specific setting method can be selected according to actual design requirements, and the embodiments of the present invention do not make specific limitations. The backlight module 102 includes a substrate 1021 and micro light-emitting elements 107 located on one side of the substrate 1021. The substrate 1021 can be a flexible substrate or a rigid substrate. The micro light-emitting elements 107 can be micro light-emitting diodes (Mini LEDs) or micro light-emitting diodes (Micro LEDs) and other micro light-emitting elements 107. The micro light-emitting elements 107 can be blue micro light-emitting elements. A light conversion layer is arranged on the side of the micro light-emitting element 107 away from the substrate 1021, so that the blue light emitted by the micro light-emitting element 107 is converted into white light. A plurality of micro light-emitting elements 107 are arranged on the substrate 1021, and the adjacent micro light-emitting elements 107 are arranged at intervals. Usually, the micro light-emitting elements 107 are arranged in an array in the light output area 104. When the display module 100 is displaying, the micro light-emitting elements 107 are turned on, so as to ensure that the light emitted by the micro light-emitting elements 107 can irradiate the display panel 101 as evenly as possible, thereby meeting the display requirements of the display panel 101; or, when the light collection element 106 is working, the micro light-emitting elements 107 close to the light collection area 103 stop working, so that external light can be incident on the light collection element 106, ensuring the imaging effect of the display module 100. A first light adjustment structure 108 is arranged between the backlight module 102 and the display panel 101. Along the thickness direction Y of the display module 100, the first light adjustment structure 108 and the light collection area 103 at least partially overlap. The light emitted by the micro light-emitting element 107 is incident on the first light adjustment structure 108, so that the light transmitted through the first light adjustment structure 108 can adjust the light output angle and converge in the orthographic projection direction of the light collection area 103, where as Figure 4As shown, a serrated microstructure 1081 may be provided on the surface of the first light adjustment structure 108 away from the backlight module 102, so that the light emitted from the first light adjustment structure 108 can be emitted vertically as much as possible, filling light at the corresponding position of the through hole 105 in the light collection area 103, thereby ensuring the overall display effect of the display module 100.

[0043] In an embodiment of the present invention, by providing a first light adjustment structure between the backlight module and the display panel, and along the thickness direction of the display module, the first light adjustment structure at least partially overlaps with the light collection area. The light emitted by the micro-light emitting elements converges in the positive projection direction of the light collection area, thereby ensuring the filling light of the light collection area and the overall display effect of the display module.

[0044] Optionally, continue to refer to Figure 1 , the display module 100 further includes a driving conversion unit (not shown in the figure). The driving conversion unit is connected to the first light adjustment structure 108 and is used to adjust the first light adjustment structure 108 to perform a fog penetration conversion. When the light collection element 106 is in a working state, the first light adjustment structure 108 is in a light-transmitting state; when the light collection element 106 is in a non-working state, the first light adjustment structure 108 is in a fogged state.

[0045] Among them, the first light adjustment structure 108 can be a material that performs fog penetration conversion according to power-on or power-off to meet the display or imaging requirements. A driving conversion unit is provided in the display module 100. The driving conversion unit can be a power supply, and the driving conversion unit is electrically connected to the first light adjustment structure 108 to supply power to the first light adjustment structure 108, thereby realizing the fog penetration conversion function. After the first light adjustment structure 108 is powered on, it can become a light-transmitting state; after power-off, it becomes a fogged state; or after the first light adjustment structure 108 is powered on, it can become a fogged state; after power-off, it becomes a light-transmitting state, which can be specifically selected according to actual design requirements. Exemplarily, taking the first light adjustment structure 108 that can become a light-transmitting state after being powered on and a fogged state after power-off as an example, when the light collection element 106 is in a working state, external light needs to be incident on the light collection element 106. At this time, the driving conversion unit supplies power to the first light adjustment structure 108, so that the first light adjustment structure 108 is in a light-transmitting state, and the external light is incident on the light collection element 106 through the display panel 101 and the first light adjustment structure 108; when the light collection element 106 is in a non-working state, at this time the display panel 101 is in a display state, and at this time the driving conversion unit stops supplying power to the first light adjustment structure 108, so that the first light adjustment structure 108 is in a fogged state, fogging the boundary between the normal display area of the display module 100 and the area where the through hole 105 is located, and at the same time enabling the light emitted by the micro-light emitting element 107 to be emitted vertically as much as possible, thereby ensuring the overall display effect of the display module 100.

[0046] Optionally, Figure 5 is a top view structural schematic diagram of a display module provided by an embodiment of the present invention. As Figure 5 shown, the micro light-emitting element 107 includes a first micro light-emitting element 1071 located on the side of the light-emitting area 104 close to the light-gathering area 103, and the first micro light-emitting elements 1071 are arranged at intervals around the light-gathering area 103.

[0047] Among them, the micro light-emitting element 107 includes a first micro light-emitting element 1071 arranged on the side of the light-emitting area 104 close to the light-gathering area 103, so that the first micro light-emitting elements 1071 are arranged at intervals around the light-gathering area 103 and a second micro light-emitting element 1072 located in the remaining light-emitting area 104. The second micro light-emitting elements 1072 are arranged in an array. The arrangement of the first micro light-emitting elements 1071 can, when the display module 100 is displaying, make the light emitted by the first micro light-emitting elements 1071, after passing through the first light adjustment structure 108, be able to supplement light to the corresponding area of the light-gathering area 103 more concentratedly, thereby ensuring the uniform display effect of the display module 100.

[0048] Optionally, Figure 6 is a structural schematic diagram of a structural film provided by an embodiment of the present invention. As Figure 6 shown, the backlight module 102 includes a structural film 109 located on the side of the micro light-emitting element 107 away from the substrate 1021. The structural film 109 includes a first surface 1091 close to the substrate 1021 and a second surface 1092 away from the substrate 1021; the first surface 1091 includes a convex structure 110, and adjacent convex structures 110 are in contact with each other. Along the direction X from the light-emitting area 104 to the light-gathering area 103, the convex height H1 of the convex structure 110 close to the light-gathering area 103 is less than the convex height H2 of the convex structure 110 away from the light-gathering area 103.

[0049] Among them, a structural film 109 is further provided in the light-emitting area 104 of the backlight module 102. The structural film 109 can be composed of 4 film layers. The structural film 109 is located on the side of the micro-light-emitting element 107 away from the substrate 1021. The structural film 109 has the function of light diffusion, and can disperse part of the light emitted by the micro-light-emitting element 107 to the light-collecting area 103, thereby ensuring the light brightness of the area corresponding to the light-collecting area 103. To ensure the light diffusion effect of the structural film 109, the surface of the structural film 109 on the side away from the substrate 1021 can be patterned, and the raised structures 110 on the first surface 1091 close to the substrate 1021 can be designed differently. The raised structures 110 can be semi-circular or semi-elliptical. The adjacent raised structures 110 are in contact with each other, and the bottom radii of the adjacent raised structures 110 are the same, so that the raised height H1 of the raised structure 110 close to the light-collecting area 103 is less than the raised height H2 of the raised structure 110 away from the light-collecting area 103. When the light passing through the structural film 109 exits near the light-collecting area 103, the light exit angle of the light is directed towards the light-collecting area 103, and then enters the central area of the first light adjustment structure 108, that is, the area corresponding to the through hole 105, to ensure the light supplement effect on the position corresponding to the light-collecting area 103, thereby reducing the difference between the light-collecting area 103 and the normal display area, and ensuring the overall display effect of the display module 100. In addition, compared with the design of the raised structure 110 on the surface of the structural film 109 in the prior art, the raised height of the raised structure 110 can be adjusted as a whole to reduce the raised height, and the light adjustment effect can also be ensured, and the display effect of the display module 100 can be improved.

[0050] Optionally, Figure 7 is a schematic structural diagram of another structural film provided by an embodiment of the present invention, as Figure 7 shown, along the direction X from the light-emitting area 104 to the light-collecting area 103, the raised height of the raised structure 110 gradually decreases.

[0051] Among them, to ensure the light exit angle adjustment effect of the light exiting through the structural film 109, the adjacent raised structures 110 are in contact with each other, and the bottom radii of the adjacent raised structures 110 are the same, which can make the raised height of the raised structure 110 gradually decrease along the direction X from the light-emitting area 104 to the light-collecting area 103. When the display module 100 is displaying, after part of the emitted light passes through the raised structure 110 with a smaller raised height, the light exit angle of the light is more likely to be directed towards the light-collecting area 103, thereby compensating the brightness of the area corresponding to the light-collecting area 103 and ensuring the overall display effect of the display module 100.

[0052] Optionally, Figure 8 is a schematic structural diagram of another structural film provided by an embodiment of the present invention, as Figure 8As shown in the figure, the backlight module 102 includes a structural film 109 on the side of the micro-light-emitting element 107 away from the substrate 1021. The structural film 109 includes a first surface 1091 on the side close to the substrate 1021 and a second surface 1092 on the side away from the substrate 1021. The first surface 1091 includes convex structures 110, and adjacent convex structures 110 are arranged at intervals.

[0053] Among them, adjacent convex structures 110 are arranged at intervals, and the bottom surface radii of adjacent convex structures 110 are the same. By designing the arrangement density of the convex structures 110, for example, the distance between adjacent convex structures 110 is the same, so that part of the emitted light passes through the spaced convex structures 110, and the light-emitting angle of the light is directed towards the light-gathering area 103, thereby compensating the brightness of the corresponding area of the light-gathering area 103 and ensuring the overall display effect of the display module 100.

[0054] Optionally, Figure 9 is a schematic structural diagram of another structural film provided by an embodiment of the present invention. As Figure 9 shown, along the direction X from the light-emitting area 104 to the light-gathering area 103, the distance W1 between adjacent convex structures 110 close to the light-gathering area 103 is greater than the distance W2 between adjacent convex structures 110 away from the light-gathering area 103.

[0055] Among them, adjacent convex structures 110 are arranged at intervals, and the bottom surface radii of adjacent convex structures 110 are the same. Along the direction X from the light-emitting area 104 to the light-gathering area 103, the distance W1 between adjacent convex structures 110 close to the light-gathering area 103 is greater than the distance W2 between adjacent convex structures 110 away from the light-gathering area 103, so that when the light passing through the structural film 109 exits near the light-gathering area 103, the light-emitting angle of the light is directed towards the light-gathering area 103, and then enters the area corresponding to the through hole 105, ensuring the brightness compensation for the corresponding position of the light-gathering area 103 and the overall display effect of the display module 100.

[0056] Optionally, Figure 10 is a schematic structural diagram of another structural film provided by an embodiment of the present invention. As Figure 10 shown, along the direction X from the light-emitting area 104 to the light-gathering area 103, the distance between adjacent convex structures 110 gradually increases.

[0057] Among them, to ensure the light-emitting angle adjustment effect of the light emitted from the structural film 109, the adjacent convex structures 110 are arranged at intervals, and the bottom surface radii of the adjacent convex structures 110 are the same. Along the direction X from the light-emitting area 104 to the light-collecting area 103, the distance between the adjacent convex structures 110 gradually increases, reducing the arrangement density of the convex structures 110. When the display module 100 is displaying, part of the emitted light passes through the spaced convex structures 110, and the light-emitting angle of the light is more likely to face the light-collecting area 103, thereby reducing the display difference between the normal display area and the area corresponding to the through hole 105 and ensuring the overall display effect of the display module 100.

[0058] Optionally, Figure 11 is a schematic structural diagram of another structural film provided by an embodiment of the present invention. Figure 12 is a schematic structural diagram of another structural film provided by an embodiment of the present invention. Figure 13 is a schematic structural diagram of another structural film provided by an embodiment of the present invention, as Figure 11 、 Figure 12 and Figure 13 shown. The backlight module 102 includes a structural film 109 on the side of the micro-light-emitting element 107 away from the substrate 1021. The structural film 109 includes a first surface 1091 close to the substrate 1021 and a second surface 1092 away from the substrate 1021. The second surface 1092 includes groove structures 111, and the adjacent groove structures 111 are arranged at intervals. Along the direction X from the light-emitting area 104 to the light-collecting area 103, the distance W3 between the adjacent groove structures 111 close to the light-collecting area 103 is greater than the distance W4 between the adjacent groove structures 111 away from the light-collecting area 103.

[0059] Among them, to ensure the light diffusion effect of the structural film 109, the surface of the structural film 109 can be patterned. As Figures 6 - 10 shown, only the convex structures 110 on the first surface 1091 close to the substrate 1021 are differentially designed; as Figure 11 shown, only the groove structures 111 on the second surface 1092 away from the substrate 1021 are differentially designed, or as Figure 13 shown, further, both the convex structures 110 on the first surface 1091 close to the substrate 1021 and the groove structures 111 on the second surface 1092 away from the substrate 1021 are differentially designed, and specific selection can be made according to actual requirements. Optionally, the shape of the groove structure 111 is a regular quadrangular prism or a regular quadrangular pyramid. Specific selection can be made according to actual design requirements, and the embodiments of the present invention do not make specific limitations. Exemplarily, as Figure 11As shown, the shape of the groove structure 111 is a regular quadrangular prism. The adjacent groove structures 111 are arranged at intervals, and the bottom surface sizes of the adjacent groove structures 111 are the same. Along the direction X from the light-emitting area 104 to the light-collecting area 103, the distance W3 between the adjacent groove structures 111 close to the light-collecting area 103 is greater than the distance W4 between the adjacent groove structures 111 far from the light-collecting area 103. When the light passing through the structure film 109 exits from the groove structure 111 close to the light-collecting area 103, the light-emitting angle of the light is oriented towards the light-collecting area 103, and then enters the area corresponding to the through hole 105, ensuring the light supplement effect for the corresponding position of the light-collecting area 103, thereby reducing the difference between the light-collecting area 103 and the normal display area and ensuring the overall display effect of the display module 100. Similarly, as Figure 12 shown, the shape of the groove structure 111 is a regular quadrangular pyramid, so that when the light passing through the structure film 109 exits from the groove structure 111 close to the light-collecting area 103, the light-emitting angle of the light is more likely to be oriented towards the light-collecting area 103, further enhancing the light collection effect, and then entering the area corresponding to the through hole 105, improving the light supplement effect for the corresponding position of the light-collecting area 103 and ensuring the overall display effect of the display module 100.

[0060] Optionally, Figure 14 is a schematic structural diagram of another structure film provided by an embodiment of the present invention. Figure 15 is a schematic structural diagram of another structure film provided by an embodiment of the present invention. As Figure 14 and Figure 15 shown, along the direction X from the light-emitting area 104 to the light-collecting area 103, the distance between the adjacent groove structures 111 gradually increases.

[0061] Among them, to further enhance the adjustment effect of the light-emitting angle of the light exiting from the structure film 109, the adjacent convex structures 110 are arranged at intervals, and the bottom surface sizes of the adjacent convex structures 110 are the same. As Figure 14 shown, the shape of the groove structure 111 is a regular quadrangular prism, or as Figure 15 shown, the shape of the groove structure 111 is a regular quadrangular pyramid. Both can make the distance between the adjacent groove structures 111 gradually increase along the direction X from the light-emitting area 104 to the light-collecting area 103, and the arrangement density of the groove structures 111 gradually decreases. When the display module 100 is displaying, after part of the exiting light passes through the groove structure 111, the light-emitting angle of the light is more likely to be oriented towards the light-collecting area 103, thereby compensating the brightness of the area corresponding to the light-collecting area 103 and ensuring the overall display effect of the display module 100.

[0062] Optionally, Figure 16 is a schematic structural diagram of another structure film provided by an embodiment of the present invention. Figure 17 is a schematic structural diagram of another structure film provided by an embodiment of the present invention. Figure 18Schematic diagram of another structural film provided by an embodiment of the present invention, as Figure 16 , Figure 17 and Figure 18 shown, the backlight module 102 includes a structural film 109 located on the side of the micro-light emitting element 107 away from the substrate 1021. The structural film 109 includes a first surface 1091 close to the substrate 1021 and a second surface 1092 away from the substrate 1021. The second surface 1092 includes a groove structure 111, and the groove structure 111 is a regular square pyramid. Along the direction X from the light-emitting area 104 to the light-gathering area 103, the height H3 of the groove structure 111 close to the light-gathering area 103 is greater than the height H4 of the groove structure 111 away from the light-gathering area 103.

[0063] Among them, as Figure 16 shown, only the groove structure 111 in the second surface 1092 on the side away from the substrate 1021 is designed differently. The adjacent groove structures 111 are in contact with each other, and the bottom surface sizes of the adjacent convex structures 110 are the same, so that the height of the groove structure 111 close to the light-gathering area 103 is greater than the height of the groove structure 111 away from the light-gathering area 103. The higher the height, when the light passing through the structural film 109 exits near the light-gathering area 103, the light-emitting angle of the light is directed towards the light-gathering area 103, and then enters the central area of the first light adjustment structure 108, that is, the area corresponding to the through hole 105, ensuring the supplementary light effect for the corresponding position of the light-gathering area 103, and then reducing the difference between the light-gathering area 103 and the normal display area, and ensuring the overall display effect of the display module 100. As Figure 17 shown, the groove structures 111 in both the first surface 1091 close to the substrate 1021 and the second surface 1092 away from the substrate 1021 are designed differently. Along the direction X from the light-emitting area 104 to the light-gathering area 103, the distance between adjacent convex structures 110 gradually increases. The adjacent groove structures 111 are in contact with each other, and the height of the groove structure 111 close to the light-gathering area 103 is greater than the height of the groove structure 111 away from the light-gathering area 103. Through the design of the convex structure 110 and the groove structure 111, the supplementary light effect for the corresponding position of the light-gathering area 103 is improved, and the overall display effect of the display module 100 is ensured. Or as Figure 18As shown, the groove structures 111 in the first surface 1091 close to the substrate 1021 and the second surface 1092 far from the substrate 1021 are differentially designed. Along the direction X from the light-emitting area 104 to the light-gathering area 103, the distance between adjacent convex structures 110 gradually increases. The adjacent groove structures 111 are arranged at intervals. The height of the groove structures 111 close to the light-gathering area 103 is greater than the height of the groove structures 111 far from the light-gathering area 103. Further reducing the arrangement density of the groove structures 111 on the side close to the light-gathering area 103 can further improve the light filling effect at the corresponding position of the light-gathering area 103 and ensure the overall display effect of the display module 100.

[0064] Optionally, Figure 19 is a schematic structural diagram of another structural film provided by an embodiment of the present invention. As Figure 19 shown, along the direction X from the light-emitting area 104 to the light-gathering area 103, the height of the groove structures 111 gradually increases.

[0065] Among them, to ensure the light output angle adjustment effect of the light emitted through the structural film 109, the adjacent groove structures 111 are in contact with each other, and the bottom surface sizes of the adjacent groove structures 111 are the same. This can make the height of the groove structures 111 gradually increase along the direction X from the light-emitting area 104 to the light-gathering area 103. When the display module 100 is displaying, after part of the emitted light passes through the groove structures 111 with a higher height, the light is more likely to gather towards the light-gathering area 103, thereby compensating the brightness of the corresponding area of the light-gathering area 103 and ensuring the overall display effect of the display module 100.

[0066] Optionally, Figure 20 is a schematic structural diagram of another display module provided by an embodiment of the present invention. As Figure 20 shown, the display module 100 further includes a second light adjustment structure 112. The second light adjustment structure 112 is located on the side of the backlight module 102 close to the display panel 101 and the second light adjustment structure 112 is arranged around the light-gathering area 103. The second light adjustment structure 112 is used to converge the light emitted by the micro light-emitting elements 107 and emit the first light adjustment structure 108.

[0067] Among them, the display module 100 is further provided with a second light adjustment structure 112. The second light adjustment structure 112 is located on the side of the backlight module 102 close to the display panel 101 and the second light adjustment structure 112 is arranged around the light-gathering area 103. After the light emitted by the micro light-emitting elements 107 passes through the structural film 109 and is emitted, it is incident on the second light adjustment structure 112, which can further converge the light and emit the first light adjustment structure 108, improve the light filling effect at the corresponding position of the light-gathering area 103, reduce the display difference between the normal display area and the light-gathering area 103, and ensure the overall display effect of the display module 100.

[0068] Optionally, Figure 21 FIG. is a schematic structural diagram of a brightness enhancement film provided by an embodiment of the present invention. As Figure 21 shown, the backlight module 102 includes a structural film 109 on a side of the micro-light emitting element 107 away from the substrate 1021 and a brightness enhancement film 113 on a side of the structural film 109 away from the substrate 1021; a plurality of light adjustment units 1131 are provided on a surface of the brightness enhancement film 113 away from the substrate 1021, and along the direction X from the light emitting area 104 to the light collecting area 103, the size of the light adjustment unit 1131 gradually decreases.

[0069] Among them, a brightness enhancement film 113 is further provided on a side of the structural film 109 away from the substrate 1021; the setting of the brightness enhancement film 113 can achieve a certain brightness enhancement effect. A plurality of light adjustment units are provided on a surface of the brightness enhancement film 113 away from the substrate 1021. Along the direction X from the light emitting area 104 to the light collecting area 103, the size of the light adjustment unit 1131 gradually decreases, so that when the display module 100 performs imaging, the light emitted by the micro-light emitting element 107 can be evenly distributed by the light adjustment unit 1131, realizing a fogging effect at the boundary between the light emitting area 104 and the light collecting area 103, reducing the risk of light leakage during photographing, and ensuring the under-screen photographing effect.

[0070] Optionally, Figure 22 FIG. is a schematic structural diagram of another display module provided by an embodiment of the present invention. As Figure 22 shown, the display module 100 further includes a third light adjustment structure 114 on a side of the micro-light emitting element 107 away from the substrate 1021. The third light adjustment structure 114 is disposed around the light collecting area 103 and at least partially contacts a side wall of the backlight module 102 close to the light collecting area 103. Along the thickness direction Y of the display module 100, the third light adjustment structure 114 at least partially overlaps with the second light adjustment structure 112. The third light adjustment structure 114 is configured to diverge the light emitted by the micro-light emitting element 107 and emit it to the second light adjustment structure 112.

[0071] Among them, the display module 100 further includes a third light ray adjustment structure 114 located on the side of the micro-light emitting element 107 away from the substrate 1021. The third light ray adjustment structure 114 is disposed around the light collection area 103 and is at least partially in contact with the side wall of the backlight module 102 close to the light collection area 103. That is, the third light ray adjustment structure 114 is disposed between the structure film 109 and the brightness enhancement film 113 on the side close to the light collection area 103 and the light collection area 103. Along the thickness direction Y of the display module 100, the third light ray adjustment structure 114 at least partially overlaps with the second light ray adjustment structure 112. After the light rays emitted by the micro-light emitting element 107 enter the third light ray adjustment structure 114, the received light rays can be diverged, which is beneficial to achieving a fogging effect, and then the light rays are emitted to the second light ray adjustment structure 112. After passing through the second light ray adjustment structure 112, the light rays are emitted in the direction of the light collection area 103 and are converged and emitted to the first light ray adjustment structure 108. After passing through the first light ray adjustment structure 108, the light rays are emitted as vertically as possible, enhancing the supplementary light for the corresponding position of the through hole 105 of the light collection area 103, and thus ensuring the overall display effect of the display module 100.
