Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display structure and display device. Background Technology

[0002] Currently, in the field of display technology, existing display structures with compatible light-sensing functions often suffer from light leakage at wide viewing angles, which seriously affects the display effect and the user's viewing experience.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this disclosure is to provide a display structure and display device that can increase the light leakage angle of the display structure to improve the display effect.

[0005] This disclosure provides a display structure having a display area and a non-display area surrounding the display area, the display structure comprising:

[0006] The display module, located in the non-display area, has an adjacent first module portion and a second module portion, wherein the second module portion is farther away from the display area relative to the first module portion;

[0007] A first light-shielding layer is disposed on the side of the first module unit near the display side of the display structure, and the first light-shielding layer is provided with a photosensitive opening;

[0015] In one exemplary embodiment of this disclosure, the projection of the light-shielding structure in the first direction coincides with the projection of the photosensitive opening in the first direction.

[0016] In one exemplary embodiment of this disclosure, the difference between the minimum distance between the second light-shielding layer and the center of the display area and the maximum distance between the photosensitive opening and the center of the display area is greater than or equal to 350 μm.

[0017] In one exemplary embodiment of this disclosure, the light-shielding structure is a mosaic structure.

[0018] In one exemplary embodiment of this disclosure, the display module includes: the display structure further includes:

[0019] A blocking structure is provided at least on the side of the second module portion away from the display area, and the blocking structure extends along the thickness direction of the display structure.

[0020] In one exemplary embodiment of this disclosure, the blocking structure is attached to the side of the second module portion away from the display area.

[0021] In one exemplary embodiment of this disclosure, the display module includes a backlight module and a first driving module, the first driving module being disposed on the side of the backlight module near the display side, the first driving module including a first module portion and a second module portion; the blocking structure is attached to the light-emitting surface of the backlight module.

[0022] In one exemplary embodiment of this disclosure, the second light-shielding layer includes:

[0023] Body part;

[0024] In the thickness direction of the display structure, the projection of the photosensitive opening in the first direction is located within the projection of the recess in the first direction.

[0025] In one exemplary embodiment of this disclosure, the maximum distance between the body portion and the center of the display area is less than or equal to the maximum distance between the photosensitive opening and the center of the display area.

[0026] This disclosure further provides a display structure having a display area and a non-display area surrounding the periphery of the display area, the display structure comprising:

[0027] Display module;

[0028] A blind aperture is disposed on the display side of the display module near the display structure and located in the display area;

[0029] A first light-shielding layer is provided around the edge of the blind hole, and the first light-shielding layer is provided with a photosensitive opening;

[0030] The second light-shielding layer is disposed on the side of the display module closer to the display side and located in the non-display area.

[0031] In one exemplary embodiment of this disclosure, the inner diameter of the first light-shielding layer is the same as the outer diameter of the blind hole.

[0032] In one exemplary embodiment of this disclosure, the display structure further includes:

[0033] A support structure is disposed on the side of the first light-shielding layer opposite to the display module, and the orthographic projection of the support structure on the display module does not overlap with the orthographic projection of the photosensitive opening on the display module.

[0034] This disclosure further provides a display device, characterized in that the display device includes the display structure provided in some of the above embodiments.

[0035] The technical solution provided in this disclosure can achieve the following beneficial effects:

[0036] This disclosure provides a display structure including a display module, a first light-shielding layer, and a second light-shielding layer. The first light-shielding layer is disposed on the side of the first module portion near the display side of the display structure to block light emitted from the display module, reducing the probability of light escaping from the non-display area. A photosensitive opening is disposed in the first light-shielding layer, allowing light from the external environment to enter the light sensor. Furthermore, by placing the first light-shielding layer in the first module portion, a certain distance is maintained between the first light-shielding layer and the edge of the display module, preventing static electricity generated during the cutting of the display structure from entering the interior of the display structure through the first light-shielding layer, thereby avoiding the influence of static electricity on the display structure.

[0037] The second light-shielding layer is located on the side of the first light-shielding layer away from the display module and in the non-display area. This arrangement allows the second light-shielding layer to further block the light emitted by the display module, further reducing the probability of light emanating from the display module escaping from the non-display area.

[0038] Based on the above structure, since no light-shielding layer is provided on the second module, the light emitted by the display module will be emitted through the position of the second module and then through the second light-shielding layer near the edge of the display area. As a result, the user can see the emitted light at a small viewing angle, which leads to obvious light leakage problems in the display structure.

[0039] In response, the display structure provided in this disclosure provides a light-shielding structure on the side of the second module near the display structure, and the light-shielding structure is positioned closer to the second module relative to the second light-shielding layer. The light-shielding structure can block the light emitted from the second module, thereby reducing the amount of light reaching the edge of the second light-shielding layer near the display area and increasing the angle of light reaching the edge of the second light-shielding layer near the display area. This increases the viewing angle from which the user can see the emitted light, thereby improving the light leakage probability of the display structure, resulting in a better display effect and improved user viewing experience.

[0040] Meanwhile, the light-shielding structure is a patterned structure, which makes the light-shielding structure have gaps inside. This can reduce or prevent the static electricity generated during the cutting of the display structure from being conducted to the first light-shielding layer through the light-shielding structure. This can also reduce or prevent static electricity from entering the interior of the display structure, thereby reducing or preventing the impact of static electricity on the display structure.

[0041] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0058] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0059] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0060] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0061] This disclosure provides a display device, which can be a mobile phone, tablet computer, television, computer monitor, vehicle display, etc. Figures 1 to 11 As shown, the display device may include a display structure 1, which can be used to display images. The display structure 1 may be a liquid crystal display structure 1, an OLED display structure 1, or the like. The display structure 1 may have a display side, which is the side of the display structure 1 capable of displaying images. The display structure 1 may have a display area 11 and a non-display area 12 surrounding the display area 11. The display area 11 is the area in the display structure 1 where images are displayed, and the non-display area 12 is the area in the display structure 1 where images are not displayed. Circuit traces, sensors, and other components of the display structure 1 can be located in the non-display area 12 to avoid affecting the display of the display structure 1 and improve the display effect.

[0062] like Figures 1 to 3 ,as well as Figures 6 to 8 As shown, the display device may further include: a frame 2, which may have a receiving space, and at least part of the display structure 1 may be located within the receiving space to provide protection for the display structure 1 using the frame 2. The frame 2 may include: a frame 21 and a base plate 22, wherein the frame 21 may be disposed around the edge of the base plate 22 to form the aforementioned receiving space together with the base plate 22.

[0063] The bezel 21 can at least surround the outer periphery of the display structure 1 to provide protection for the outer periphery of the display structure 1. The bezel 21 can be made of metal, such as aluminum or aluminum alloy, to ensure that the bezel 21 has high structural strength and light weight. However, it is not limited to this; the bezel 21 can also be made of other metals, or it can also be made of plastic or other materials, depending on the actual situation.

[0064] like Figure 2 , Figure 3 and Figure 9 As shown, the display structure 1 may include a display module 13. The display module 13 may have a light-emitting function to provide a light source for the display of the display structure 1 or to be used directly to display images.

[0065] In some embodiments, when the display structure 1 is a liquid crystal display structure 1, the display module 13 may include a backlight module 131 and a first driving module 132. The backlight module 131 provides a light source for the display structure 1. The first driving module 132 may be disposed on the side of the backlight module 131 near the display side of the display structure 1. The first driving module 132 may include a driving array, a first electrode layer 1323, a first alignment film 1324, a liquid crystal layer 1325, a second alignment film, and a second electrode layer 1327.

[0066] The driving array can be disposed on the light-emitting side of the backlight module 131. The driving array can include multiple thin-film transistors arranged in an array, and each thin-film transistor can correspond to a pixel unit. The first electrode layer 1323 can be electrically connected to the driving array to apply a voltage signal to the first electrode layer 1323 through the driving array. The first electrode layer 1323 and the driving array can be disposed on the same layer, or the first electrode layer 1323 can cover the driving array.

[0067] The first alignment film 1324 and the second alignment film can be disposed on the side of the first electrode layer 1323 opposite to the backlight module 131, and the second alignment film is farther away from the backlight module 131 relative to the first alignment film 1324. The first alignment film 1324 can be electrically connected to the first electrode layer 1323. The liquid crystal layer 1325 can be disposed between the first alignment film 1324 and the second alignment film 1326. The second electrode layer 1327 can be disposed on the side of the second alignment film 1326 away from the backlight module 131, and the second electrode layer 1327 can be electrically connected to the second alignment film.

[0068] During the operation of the display module 13, the driving array can apply a driving voltage to the first electrode layer 1323. At this time, the first electrode layer 1323 can apply a driving voltage to the first alignment film 1324, and the second electrode layer 1327 can apply a driving voltage to the second alignment film 1326. The first alignment film 1324 and the second alignment film 1326 are used to control the deflection direction and deflection angle of the liquid crystal molecules in the liquid crystal layer 1325, thereby enabling the adjustment of the brightness of the light emitted from the liquid crystal layer 1325 to achieve image display of the display structure 1.

[0069] In other embodiments, when the display structure 1 is an OLED display structure 1, the display module 13 may include a second driving module and a light-emitting module. The second driving module and the light-emitting module may be stacked. The second driving module may drive the light-emitting module to emit light for displaying images. The light-emitting module may include a third electrode layer, an organic light-emitting material layer, and a fourth electrode layer stacked sequentially. The second driving module may apply a voltage to the third electrode layer to drive the organic light-emitting material layer to emit light, thereby achieving the display function.

[0070] In some embodiments, such as Figure 4 and Figure 10 As shown, the display structure 1 may further include a light sensor 23. The light sensor 23 can be disposed on the display module 13, for example, it can be disposed on the driving module, etc., to sense changes in ambient light. The display structure 1 can adjust its brightness, turn off the screen, and perform other functions based on the changes in ambient light detected by the light sensor 23. Therefore, this display structure 1 can provide a better user experience.

[0071] In some embodiments of this disclosure, such as Figures 1 to 7As shown, the portion of the display module 13 located in the non-display area 12 may have an adjacent first module portion 134 and a second module portion 135. The second module portion 135 may be located away from the display area 11 relative to the first module portion 134. That is, it can be understood that the second module portion 135 is located on the periphery of the first module portion 134, and the second module portion 135 is close to the edge of the display module 13. The aforementioned light sensor 23 may be disposed in the first module portion 134.

[0072] The display structure 1 may further include a first light-shielding layer 14. The first light-shielding layer 14 may be disposed on the side of the first module portion 134 near the display side of the display structure 1 to block the light emitted by the display module 13, reducing the probability of light emitted by the display module 13 escaping from the non-display area 12. The first light-shielding layer 14 is provided with a photosensitive opening 141, allowing light from the external environment to enter the light sensor 23 through the photosensitive opening 141. Simultaneously, by disposing the first light-shielding layer 14 on the first module portion 134, a certain distance can be maintained between the first light-shielding layer 14 and the edge of the display module 13, preventing static electricity generated when the display structure 1 is cut along the cutting line 25 from entering the interior of the display structure 1 through the first light-shielding layer 14, thereby preventing static electricity from affecting the display structure 1.

[0073] The material of the first light-shielding layer 14 can be ink, but is not limited to this. The material of the first light-shielding layer 14 can also be black photoresist, etc., and can be selected and set according to actual needs.

[0074] The display structure 1 may further include a second light-shielding layer 15. The second light-shielding layer 15 may be disposed on the side of the first light-shielding layer 14 away from the display module 13, and may be located in the non-display area 12. With this arrangement, the second light-shielding layer 15 can be used to further block the light emitted by the display module 13, further reducing the probability of the light emitted by the display module 13 escaping from the non-display area 12.

[0075] The material of the second light-shielding layer 15 can be ink, but is not limited to this. The material of the second light-shielding layer 15 can also be black photoresist, etc., and can be selected and set according to actual needs.

[0076] Furthermore, in the first direction X, the maximum distance S2 between the photosensitive aperture 141 and the center of the display area 11 can be less than the minimum distance S1 between the second light-shielding layer 15 and the center of the display area 11. That is, it can be understood that the end of the second light-shielding layer 15 near the display area 11 is farther away from the display area 11 relative to the entire photosensitive aperture 141. The first direction X can be the distribution direction of the first module portion 134 and the second module portion 135. With this arrangement, the second light-shielding layer 15 can be prevented from blocking the photosensitive aperture 141, thereby ensuring that light from the external environment can enter the photosensitive aperture 141. At the same time, through the above arrangement, there can be a distance between the edge of the second light-shielding layer 15 near the display area 11 and the hole wall of the photosensitive aperture 141 away from the display area 11, thereby increasing the light-receiving range of the photosensitive aperture 141, so that light with a larger angle α1 can also enter the photosensitive aperture 141, thereby improving the light-sensing effect of the display structure 1.

[0077] In some embodiments, since no light-shielding layer is provided on the second module 135, the light emitted by the second module 135 of the display module 13 and / or the light reflected by the frame 21 of the display device may be emitted through the position of the second module 135, and the light with a small angle may be emitted through the second light-shielding layer 15 near the edge of the display area 11, so that the user can see the emitted light at a small viewing angle, which leads to obvious light leakage problem in the display structure 1.

[0078] To address the aforementioned technical issues, the display structure 1 may also include a light-shielding structure 16. The light-shielding structure 16 may be disposed on the side of the second module portion 135 near the display side of the display structure 1, and the light-shielding structure 16 may be positioned closer to the second module portion 135 relative to the second light-shielding layer 15, with the edge of the light-shielding structure 16 away from the display area 11 being flush with the edge of the second module portion 135 away from the display area 11.

[0079] This configuration allows the light emitted from the second module section 135 to be blocked by the light-shielding structure 16, thereby reducing the amount of light reaching the edge of the second light-shielding layer 15 near the display area 11 and increasing the angle β2 of the light reaching the edge of the second light-shielding layer 15 near the display area 11. This increases the viewing angle β1 from which the user can see the emitted light, thereby improving the light leakage probability of the display structure 1, resulting in a better display effect and enhancing the user's viewing experience.

[0080] Meanwhile, the light-shielding structure 16 can be a patterned structure, that is, the light-shielding structure 16 can have multiple spaced-apart blocking blocks, with gaps between any two adjacent blocking blocks. Since current cannot be conducted through the gaps, the static electricity generated during the cutting of the display structure 1 can be reduced or prevented from being conducted to the first light-shielding layer 14 through the light-shielding structure 16, thus reducing or preventing static electricity from entering the interior of the display structure 1, thereby reducing or preventing the impact of static electricity on the display structure 1.

[0081] In some embodiments, the light-shielding structure 16 can be a mosaic structure. This configuration allows for gaps within the light-shielding structure 16, which completely isolate the conduction of static electricity, thereby completely preventing static electricity from entering the display structure 1 and further improving the product yield of the display structure 1.

[0082] However, it is not limited to this. The light-shielding structure 16 can also be other structures, which can be selected and set according to the actual situation, and all of these are within the protection scope of this disclosure.

[0083] In some embodiments, the projection of the light-shielding structure 16 onto the thickness direction Y of the display structure 1 can be at least in contact with the projection of the first light-shielding layer 14 onto the thickness direction Y of the display structure 1. This arrangement reduces the distance between the light-shielding structure 16 and the first light-shielding layer 14 in the first direction X, thereby reducing the probability of light escaping from the gap between the light-shielding structure 16 and the first light-shielding layer 14. This further reduces the amount of light reaching the edge of the second light-shielding layer 15 near the display area 11 and further increases the angle of light reaching the edge of the second light-shielding layer 15 near the display area 11, thereby further increasing the viewing angle from which the user can see the emitted light, and further improving the light leakage problem of the display structure 1.

[0084] Furthermore, the light-shielding structure 16 and the first light-shielding layer 14 can be disposed on the same layer. This arrangement completely eliminates the gap between the light-shielding structure 16 and the first light-shielding layer 14, thus completely preventing light from escaping through the gap between them. Simultaneously, this arrangement allows the light-shielding structure 16 and the first light-shielding layer 14 to be formed simultaneously in the same manufacturing step, reducing the manufacturing difficulty of the display structure 1 and improving its manufacturing efficiency.

[0085] In some embodiments, such as Figure 6 As shown, the projection of the light-shielding structure 16 in the first direction X and the projection of the photosensitive opening 141 in the first direction X can at least overlap. The projection of the light-shielding structure 16 in the first direction X is... Figure 6 In the image, the projection of the light-shielding structure 16 onto the reference plane T1 is shown along the dashed line. The projection of the photosensitive opening 141 onto the first direction X is... Figure 6In the diagram, the projection of the photosensitive opening 141 onto the reference plane T1 is shown along the dashed line. It is understood that the overlapping described here can include three cases: first, the projection of the light-shielding structure 16 in the first direction X overlaps with the projection of the photosensitive opening 141 in the first direction X; second, the projection of the light-shielding structure 16 in the first direction X coincides with the projection of the photosensitive opening 141 in the first direction X; and third, the projection of the photosensitive opening 141 in the first direction X is located within the projection of the light-shielding structure 16 in the first direction X. This arrangement ensures that the light-shielding range of the light-shielding structure 16 can at least cover a portion of the area where the photosensitive opening 141 is located, thus preventing light from escaping from the edge of the second light-shielding layer 15 in the area where the photosensitive opening is located.

[0086] Furthermore, the projection of the light-shielding structure 16 in the first direction X can coincide with the projection of the photosensitive opening 141 in the first direction X. That is, it can be understood that the length of the light-shielding structure 16 and the length of the photosensitive opening 141 can be the same. With this configuration, it can be ensured that the light-shielding range of the light-shielding structure 16 can cover the entire area where the photosensitive opening 141 is located, thereby further improving the ability of the light-shielding structure 16 to block the light emitted from the area where the photosensitive opening 141 is located, and further preventing light from escaping from the edge of the second light-shielding layer 15 in the area where the photosensitive opening is located.

[0087] Furthermore, the projection of the photosensitive opening 141 in the first direction X can be located within the projection of the light-shielding structure 16 in the first direction X. That is, it can be understood that the length of the light-shielding structure 16 can be greater than the length of the photosensitive opening 141. With this configuration, the ability of the light-shielding structure 16 to block light emitted from the area where the photosensitive opening 141 is located can be further improved, and the probability of light escaping from the edge of the second light-shielding layer 15 in the area where the photosensitive opening is located can be further reduced.

[0088] In some embodiments, such as Figures 1 to 3 As shown, the difference between the minimum distance S1 between the second light-shielding layer 15 and the center of the display area 11, and the maximum distance S2 between the photosensitive aperture 141 and the center of the display area 11, can be greater than or equal to 350μm, for example: 350μm, 360μm, 370μm, 380μm, 390μm, 400μm, etc. This arrangement ensures sufficient distance between the edge of the second light-shielding layer 15 near the display area 11 and the wall of the photosensitive aperture 141 away from the display area 11, thereby guaranteeing the light-receiving range of the photosensitive aperture 141 and increasing the maximum light-receiving angle of the light entering the photosensitive aperture 141, so that the maximum light-receiving angle α1 can be greater than or equal to 50°, thus further improving the light-sensing effect of the display structure 1.

[0089] After testing the display structure 1 provided in this disclosure and the display structure 1 without the light-shielding structure 16, the test results show that: when the display structure 1 is without the light-shielding structure 16, the angle β2 of the light reaching the edge of the second light-shielding layer 15 near the display area 11 is 15.7°, and the viewing angle β1 of the emitted light visible to the user is 14.6°. When the display structure 1 is the display structure 1 provided in this disclosure, the angle β2 of the light reaching the edge of the second light-shielding layer 15 near the display area 11 is 18.73°, and the viewing angle β2 of the emitted light visible to the user is 48.28°. Based on the specific test data, it can be confirmed that the display structure 1 provided in this disclosure can significantly increase the angle of the emitted light visible to the user, effectively improving the light leakage problem of the display structure 1.

[0090] In some embodiments of this disclosure, such as Figure 3 As shown, the display structure 1 may further include a blocking structure 17. The blocking structure 17 may be disposed at least on the side of the second module portion 135 away from the display area 11, and the blocking structure 17 may extend along the thickness direction Y of the display structure 1. With this arrangement, the blocking structure 17 can block the light reflected from the frame 21, thereby preventing the light reflected from the frame 21 from escaping from the edge of the second light-shielding layer 15, thus further improving the light leakage problem of the display structure 1.

[0091] The further blocking structure 17 can be attached to the side of the second module 135 away from the display area 11 to prevent light reflected from the frame 21 from escaping through the gap between the blocking structure 17 and the second module 135. This can further prevent light reflected from the frame 21 from escaping from the edge of the second light-shielding layer 15, thereby further improving the light leakage problem of the display structure 1.

[0092] In some embodiments, when the display structure 1 is a liquid crystal display structure 1, the blocking structure 17 can be attached to the light-emitting surface of the backlight module 131. That is, there is no gap between the bottom of the blocking structure 17 and the light-emitting surface of the backlight module 131. This arrangement can prevent light reflected from the frame 21 from escaping through the gap between the backlight module 131 and the blocking structure 17.

[0093] In this embodiment, the display structure 1 may further include a color filter 24, which may be disposed on the side of the first light-shielding layer 14 away from the backlight module 131. The color filter 24 may include a color filter substrate 241 and a first polarizing layer 242 located on the surface of the color filter substrate 241 for adjusting the color of light, thereby realizing the display of an image. The blocking structure 17 may extend along the thickness direction Y, such that the blocking structure 17 may be located on the side of the color filter 24 away from the display area 11, so as to further block the light reflected from the frame 21.

[0094] The first driving module 132 may further include a second polarizing layer 1321 and a driving substrate 1322 located on the surface of the second polarizing layer 1321. The driving array may be disposed on the side of the first driving substrate 1322 facing away from the backlight module 131. The blocking structure 17 may also be located on the side of the second polarizing layer 1321 and the first driving substrate 1322 away from the display area 11 to further block the light reflected from the bezel 21.

[0095] The display structure 1 may further include a cover plate 27. The projection of the cover plate 27 in the thickness direction Y can cover the projection of the display module 13 in the thickness direction Y, thereby providing protection for the display module 13 and other structures. The aforementioned second light-shielding layer 15 can be disposed on the side of the cover plate 27 near the backlight module 131. When the display structure 1 is a liquid crystal display structure 1, the cover plate 27 can be disposed on the side of the first polarizing layer 242 away from the backlight module 131 and bonded to the first polarizing layer 242 by the adhesive layer 26.

[0096] The side of the blocking structure 17 near the cover plate 27 can be in contact with the cover plate 27, and the side of the blocking structure 17 away from the display area 11 can be flush with the side of the cover plate 27 away from the display area 11, or the side of the blocking structure 17 away from the display area 11 is closer to the display area 11 than the side of the cover plate 27 away from the display area 11, so as to ensure that the cover plate 27 can provide protection for the blocking structure 17.

[0097] The material of the blocking structure 17 can be photocurable adhesive, but is not limited to this. The material of the blocking structure 17 can also be photoresist, etc., and can be selected and set according to the actual situation. All of these are within the protection scope of this disclosure.

[0098] In one embodiment of this disclosure, such as Figure 1 and Figure 7 As shown, the second light-shielding layer 15 may include a body portion 151 and a recessed portion 152. Specifically, in the thickness direction Y of the display structure 1, the projection of the photosensitive opening 141 in the first direction X can be located within the projection of the recessed portion 152 in the first direction X. That is, it can be understood that when viewing the projections of the photosensitive opening 141 in the first direction X and the recessed portion 152 in the first direction X from a viewing angle along the thickness direction Y of the display structure 1, the projection of the photosensitive opening 141 in the first direction X can be located within the projection of the recessed portion 152 in the first direction X. Specifically, the projection of the photosensitive opening 141 in the first direction X can be... Figure 7 In the image, the projection of the photosensitive opening 141 onto the reference plane T1 is shown along the dashed line. The projection of the recess 152 onto the first direction X can be... Figure 7In the image, the recessed portion 152 is projected onto the reference plane T1 along the dotted line. This arrangement ensures that there is sufficient distance between the second light-shielding layer 15 and the photosensitive opening 141.

[0099] Furthermore, the maximum distance S3 between the main body 151 and the center of the display area 11 can be less than or equal to the maximum distance S2 between the photosensitive opening 141 and the center of the display area 11. Since the main body 151 does not block the light entering the photosensitive opening 141, this arrangement can increase the width of the main body 151, improve the light blocking effect of the main body 151, and reduce the probability of light leakage in the display structure 1.

[0100] In another embodiment of this disclosure, such as Figures 8 to 11 As shown, the display structure 1 may include a blind aperture 18. The blind aperture 18 can be located on the side of the display module 13 closest to the display side of the display structure 1, and can be located in the display area 11. It should be noted that the blind aperture 18 is a hole for mounting components such as sensors and cameras. The portion of the display module 13 located at the blind aperture 18 does not emit light, thus preventing light from passing through the blind aperture 18. Therefore, although the blind aperture 18 is located in the display area 11, the area where the blind aperture 18 is located does not display an image. For example, when the display structure 1 is a liquid crystal display structure 1, a through-hole 133 can be provided in the area where the blind aperture 18 is located in the backlight module 131, and the backlight module 131 does not emit light at the through-hole 133.

[0101] The aforementioned first light-shielding layer 14 can be disposed around the edge of the blind aperture 18. This arrangement allows the photosensitive aperture 141 to be located away from the frame 21, thus preventing light reflected from the frame 21 from escaping through the photosensitive aperture 141. This prevents the user from seeing light from the location of the photosensitive aperture 141, effectively improving the light leakage problem of the display structure 1. Simultaneously, since the blind aperture 18 is located in the display area 11 and the second light-shielding layer 15 is located in the non-display area 12, there is a significant distance between the blind aperture 18 and the second light-shielding layer 15. This also results in a significant distance between the photosensitive aperture 141 and the second light-shielding layer 15, preventing the second light-shielding layer 15 from affecting the photosensitive aperture 141. This further increases the light-receiving range of the photosensitive aperture 141, allowing light with a large angle α1 to enter the photosensitive aperture 141, thereby improving the light-sensing effect of the display structure 1.

[0102] Furthermore, since there is a large distance between the photosensitive opening 141 and the second light-shielding layer 15, it is not necessary to reduce the width of the second light-shielding layer 15 to avoid blocking the light entering through the photosensitive opening 141. Thus, with the above arrangement, the second light-shielding layer 15 can have a sufficient width to cover the non-display area 12, thereby effectively blocking the light emitted by the display module 13 located in the non-display area 12 and the light reflected from the frame 21, further reducing the probability of light leakage from the display structure 1 at large viewing angles.

[0103] In some embodiments, the inner diameter of the first light-shielding layer 14 and the outer diameter of the blind aperture 18 can be the same. This arrangement ensures that there is no gap between the inner peripheral surface of the first light-shielding layer 14 and the outer peripheral surface of the blind aperture 18, preventing some light from escaping between the inner peripheral surface of the first light-shielding layer 14 and the outer peripheral surface of the blind aperture 18, thus avoiding light leakage between the inner peripheral surface of the first light-shielding layer 14 and the outer peripheral surface of the blind aperture 18 in the display structure 1.

[0104] like Figure 11 As shown, the display structure 1 may further include a support structure 19. The support structure 19 may be disposed on the side of the first light-shielding layer 14 facing away from the display module 13 to support the first light-shielding layer 14. Furthermore, the orthographic projection of the support structure 19 onto the display module 13 does not overlap with the orthographic projection of the photosensitive opening 141 onto the display module 13, to avoid the support structure 19 blocking the light entering the photosensitive opening 141 and to ensure the light-entry angle and light-entry range of the photosensitive opening 141. The material of the support structure 19 may be photocurable adhesive, but is not limited to this; the support structure 19 may also be made of photoresist or other materials, and the choice can be made according to the actual situation.

[0105] In some embodiments, such as Figure 9 As shown, the base plate 22 of the display device includes a base plate portion 221 and a side plate portion 222 connected to the base plate portion 221 in the blind hole 18 region. The base plate portion 221 can be used to protect the bottom surface of the display module 13, and the side plate portion 222 can be used to protect the inner wall of the through hole 133 of the display module 13.

[0106] In this embodiment, the display structure 1 may further include a light-blocking structure 20. The light-blocking structure 20 may be disposed at least between the inner wall of the through hole 133 and the side plate portion 222 to prevent light emitted from the display module 13 from being reflected by the side plate portion 222 to the photosensitive opening 141, thereby further preventing light leakage from the photosensitive opening 141 and further improving the light leakage problem of the display structure 1. At the same time, this arrangement can also block the light emitted by the display module 13, preventing the light emitted by the display module 13 from escaping from the blind hole 18 region.

[0107] When the display structure 1 includes a backlight module 131, a through hole 133 can be provided on the backlight module 131, and a light-blocking structure 20 can be provided at least between the backlight module 131 and the side panel portion 222.

[0108] Furthermore, the through hole 133 can extend along the thickness direction Y to the second polarizing layer 1321. At this time, the light blocking structure 20 can also be disposed between the second polarizing layer 1321 and the side plate portion 222 to further improve the light blocking effect of the light blocking structure 20.

[0109] The material of the light-blocking structure 20 can be photocurable adhesive, but it is not limited to this. The light-blocking structure 20 can also be made of photoresist or other materials, and the selection and setting can be made according to the actual situation.
