Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0061] Some display modules need to attach polarizers to the screen. Polarizers can select incident light and only allow light of a specific polarization to pass through. They can eliminate or reduce light reflection and refraction, thereby changing the propagation direction and vibration direction of light. Polarizers can be used to eliminate reflections and glare and improve image quality. In some cases, OLED (Organic Electroluminescence Display) modules can be circular polarizers, and LCD (Liquid Crystal Display) modules can be linear polarizers. In some related technologies, the display module has a blind hole screen or a notch screen. Some models will have black spots in the hole area after reliability testing.

[0062] The present application provides a display module, which can reduce the problem of black spots in the hole area of ​​the display module and improve the display effect of the display module.

[0063] See also Figure 1 The display module 20 in the example of the present application can be used in the electronic device 100 , and the display module 20 can be used to display a preset image on the electronic device 100 .

[0064] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The present application proposes an example of a display module 20 , which includes a screen body 210 and a polarizer 220 .

[0065] Please refer to Figure 7 The screen body 210 has a light emitting surface 212 and a backlight surface 213 which are arranged opposite to each other. The screen body 210 is provided with a first hole 211 which connects the light emitting surface 212 and the backlight surface 213 .

[0066] The screen 210 may have pixel components, which may be arranged in a preset manner. The light emitting surface 212 and the backlight surface 213 may be two surfaces disposed opposite to each other on the screen 210, and the light emitting surface 212 and the backlight surface 213 may be two surfaces of the screen 210 along the thickness direction.

[0067] The first hole 211 is a through hole opened on the screen body 210. The first hole 211 passes through to the light-emitting surface 212. In the example of this application, the extension direction of the first hole 211 is defined as the first direction 5a. The first hole 211 in this example can be used to form a space for installing a camera module or other functional components. One end of the first hole 211 away from the light-emitting surface 212 is connected to the backlight surface 213. The first hole 211 in this example is a through hole that passes through the screen body 210, so as to facilitate wiring when installing structures such as a camera module in the first hole 211, which can help reduce the difficulty of installing the camera module of the electronic device 100.

[0068] The polarizer 220 includes a polarizer body 221 and a folding portion 222 connected to the polarizer body 221 . The polarizer body 221 is attached to the light emitting surface 212 . The folding portion 222 is connected to a side of the polarizer body 221 facing the screen body 210 and extends into the first hole 211 .

[0069] The polarizer 220 is used to select incident light to improve the image display quality of the display module 20. The polarizer body 221 is attached to the light emitting surface 212, which means that the polarizer body 221 is installed on the light emitting surface 212. In this example, the polarizer body 221 can be bonded to the light emitting surface 212 by colloid, or the polarizer body 221 can be connected to the screen body 210 by other methods. In this example, the area of ​​the polarizer body 221 and the light emitting surface 212 can be equal or unequal.

[0070] The folding portion 222 is connected to the polarizer body 221 so that the folding portion 222 can form an integral structure with the polarizer body 221. In this example, the folding portion 222 is connected to the side of the polarizer body 221 facing the screen body 210, so that the folding portion 222 forms a protruding structure on the side of the polarizer body 221 facing the screen body 210. The folding portion 222 in this example can be a convex rib protruding from the side of the polarizer body 221 facing the screen body 210, and the folding portion 222 can also be a structure formed by partially bending the polarizer body 221. The folding portion 222 is used to form a protruding shielding structure on the side of the polarizer body 221 facing the screen body 210, and the folding portion 222 can completely block the entire gap where the screen body 210 and the light emitting surface 212 meet, and the folding portion 222 can also partially block the gap where the screen body 210 and the light emitting surface 212 meet. In order to facilitate the molding of the polarizer 220 , the folding portion 222 in this example may be a protruding structure formed by partially bending the polarizer body 221 at a position corresponding to the first hole 211 .

[0071] Please refer again Figure 3 and Figure 4 In this example, the portion of the polarizer body 221 corresponding to the first hole 211 may also be cut, and the cutting may be laser cutting, and a cutting line 2222 is formed by cutting, and the cutting line 2222 separates the portion of the polarizer body 221 corresponding to the first hole 211 to form a plurality of submodules 2221, and the plurality of submodules 2221 are bent toward the first hole 211, so that the plurality of submodules 2221 form a folding portion 222 on the side of the polarizer body 221 facing the first hole 211. In this example, the number of submodules 2221 is at least two, and the depths of the plurality of submodules 2221 in the first hole 211 may be equal or unequal. Optionally, the cutting line 2222 in this example can separate the portion of the polarizer body 221 corresponding to the first hole 211 to form a plurality of sub-modules 2221 of equal area, and the plurality of sub-modules 2221 can be respectively bent into the first hole 211 so that the plurality of sub-modules 2221 can form a plurality of folding portions 222 of equal volume or close volume in the first hole 211.

[0072] The folding portion 222 is extended into the first hole 211, which means that the folding portion 222 can partially protrude from the first hole 211, and the portion of the folding portion 222 extending into the first hole 211 can be used to form a shield at the junction of the light-emitting surface 212 and the polarizer body 221. In this example, when the folding portion 222 extends into the first hole 211, on the one hand, the folding portion 222 can block the water vapor from flowing to the junction of the light-emitting surface 212 and the polarizer body 221, and on the other hand, the folding portion 222 can extend the flow path of the water vapor to the junction of the light-emitting surface 212 and the polarizer body 221, so as to reduce the accumulation of water vapor at the junction of the light-emitting surface 212 and the polarizer body 221, reduce the influence of water vapor on the pixel components of the screen body 210, and further reduce the failure problem of the pixel components near the first hole 211, and further reduce the possibility of black spots on the screen body 210 near the first hole 211, which helps to improve the image display quality of the display module 20.

[0073] In this example, it is assumed that the direction from the light-emitting surface 212 to the backlight surface 213 is the first direction 5a, the thickness direction of the portion of the folded portion 222 extending into the first hole 211 can be the second direction 5b, and the thickness of the portion of the folded portion 222 in the first hole 211 can be consistent with or inconsistent with the thickness of the polarizer body 221; along the first direction 5a, the portions between the folded portion 222 extending into the first hole 211 can be set with equal thickness or with unequal thickness. In this example, a camera module can be installed in the first hole 211, and the folded portion 222 can be arranged on the periphery of the camera module; the folded portion 222 in this example can be used to form an annular structure on the outside of the camera module to block the gap between the camera module and the inner wall surface of the first hole 211, thereby improving the sealing of the junction between the light-emitting surface 212 and the polarizer body 221. Optionally, the folded portion 222 can also partially block the gap between the camera module and the inner wall surface of the first hole 211.

[0074] In some examples, the folded portion 222 is at least partially attached to the inner wall of the first hole 211. The folded portion 222 can be at least partially attached to the inner wall of the first hole 211 to reduce the gap between the folded portion 222 and the inner wall of the first hole 211. In this example, the portion of the folded portion 222 extending to the inside of the first hole 211 can be at least partially bonded to the inner wall of the first hole 211 to prevent water vapor from flowing through the gap between the folded portion 222 and the inner wall of the first hole 211 to the junction of the polarizer body 221 and the light emitting surface 212. Optionally, the portion of the folded portion 222 extending to the inside of the first hole 211 can be attached to the inner wall of the first hole 211 to increase the contact area between the folded portion 222 and the inner wall of the first hole 211, further blocking the flow of water vapor.

[0075] In some examples, the polarizer body 221 and the folding portion 222 are integrally arranged, and the portion of the polarizer body 221 corresponding to the first hole 211 is at least partially bent toward the backlight surface 213 to form the folding portion 222. In this example, the polarizer body 221 and the folding portion 222 are integrally arranged, which means that the polarizer body 221 and the folding portion 222 are an integral structure, and the folding portion 222 is formed by partially bending the portion of the polarizer body 221 corresponding to the first hole 211. In this example, the folding portion 222 can be attached to the inner wall surface of the first hole 211 after bending. Optionally, after the folding portion 222 is bent to form, a ring-shaped structure can be formed in the first hole 211 to form a ring-shaped blocking structure in the first hole 211. In some examples, after the folding portion 222 is bent to form, at least one of the thickness and length of the folding portion 222 at different positions along the circumferential direction of the first hole 211 may be unequal.

[0076] In some examples, the folding portion 222 is arranged in an annular shape along the inner wall surface of the first hole 211. In this example, the folding portion 222 can be arranged in an annular shape around the inner wall surface of the first hole 211, so that the folding portion 222 forms an annular blocking area in the first hole 211, increasing the shielding area of ​​the folding portion 222 on the inner wall surface of the first hole 211. Optionally in this example, the folding portion 222 can form a continuous annular structure on the inner side of the first hole 211, and the hollow area formed on the inner side of the folding portion 222 can be used to accommodate functional components such as a camera module.

[0077] In some examples, there are multiple folding portions 222, and the multiple folding portions 222 are arranged along the circumference of the first hole 211. In this example, by providing multiple folding portions 222, when the folding portions 222 are extended into the first hole 211, the mutual traction between the folding portions 222 can be reduced, thereby reducing the damage of the folding portions 222. In some examples, a sealant layer 240 can be provided at the junction of adjacent folding portions 222, and the gap between adjacent folding portions 222 is sealed by the sealant layer 240. In some examples, the folding portion 222 is integrally provided with the polarizer body 221, and the portion of the polarizer body 221 corresponding to the first hole 211 is at least partially bent toward the backlight surface 213 to form the folding portion 222, and multiple folding portions 222 can be bent toward the backlight surface 213 respectively, and multiple folding portions 222 can also be bent toward the backlight surface 213 simultaneously. Since the multiple folding portions 222 can be independent of each other, the mutual interference of the multiple folding portions 222 during the bending process is reduced, and the multiple folding portions 222 are not easily damaged during the bending operation. In some examples, the portion of the polarizer body 221 corresponding to the first hole 211 can be cut to form multiple sub-modules 2221 by cutting the portion of the polarizer body 221 corresponding to the first hole 211, and then the multiple sub-modules 2221 are bent to form multiple folding portions 222.

[0078] In some examples, the folding portion 222 is provided with a sealant layer 240; the sealant layer 240 may be a liquid optically transparent resin (OCR). The sealant layer 240 may be used to form a sealing structure on the folding portion 222. The sealant layer 240 may be used to block the gap between the folding portion 222 and the screen body 210. Optionally, the sealant layer 240 may only cover the gap between the folding portion 222 and the screen body 210; optionally, the sealant layer 240 may also cover the entire surface of the folding portion 222; optionally, the sealant layer 240 may only cover the gap where the folding portion 222 and the light-emitting surface 212 of the screen body 210 meet. In some examples, the space formed by the folding portion 222 may be filled with the sealant layer 240. In some examples, the sealant layer 240 may be filled in the first hole 211.

[0079] In some examples, a sealant layer 240 is provided in the gap between the folded portion 222 and the screen body 210. The sealant layer 240 in this example can be used only to seal the gap between the folded portion 222 and the screen body 210. The gap between the screen body 210 and the folded portion 222 can be a gap between an end of the folded portion 222 away from the polarizer body 221 and the surface of the screen body 210, or a gap between a portion of the folded portion 222 located in the first hole 211 and the inner wall surface of the first hole 211, or a gap between an end of the folded portion 222 close to the light emitting surface 212 and the screen body 210.

[0080] See also Figure 5In some examples, the sealant layer 240 covers the side surface of the folded portion 222 facing away from the inner wall surface of the first hole 211. After the folded portion 222 extends into the first hole 211, the side surface of the folded portion 222 facing the inner wall surface of the first hole 211 can be the outer surface of the folded portion 222, and the side surface of the folded portion 222 opposite to the outer surface can be the inner surface of the folded portion 222, which is attached to the inner wall surface of the first hole 211, and the sealant layer 240 can cover the inner surface of the folded portion 222. The sealant layer 240 in this example can form a film-like structure on the surface of the folded portion 222 to seal the gap between the folded portion 222 and the inner wall surface of the first hole 211. The area of ​​the outer peripheral surface of the membrane structure formed by the sealant layer 240 may be consistent with the area of ​​the inner surface of the folding portion 222; optionally, when the folding portion 222 is formed by bending a plurality of submodules 2221 at the position corresponding to the first hole 211 on the polarizer body 221, the membrane structure formed by the sealant layer 240 may also cover the gap between adjacent folding portions 222. Optionally, in this example, the inner surface of the folding portion 222 may be enclosed to form a hole-like structure, and the hole-like structure enclosed by the inner surface of the folding portion 222 may be coaxially arranged with the first hole 211.

[0081] In some examples, a second hole 224 is formed at a position of the polarizer body 221 corresponding to the first hole 211 , and the folding portion 222 is at least partially disposed at one end of the second hole 224 facing the screen body 210 ; the second hole 224 is filled with a sealant layer 240 .

[0082] The second hole 224 corresponds to the first hole 211 of the screen body 210 , which means that when the polarizer body 221 is projected onto the light emitting surface 212 along the first direction 5 a , the second hole 224 at least partially overlaps with the first hole 211 .

[0083] The folding portion 222 is at least partially disposed at one end of the second hole 224 facing the screen body 210, which means that the folding portion 222 can extend from the second hole 224 toward the first hole 211 and at least partially extend into the first hole 211, or the folding portion 222 is connected to the side of the polarizer body 221 facing the screen body 210 and extends into the first hole 211. In this example, the folding portion 222 can be a protruding structure protruding from the side of the polarizer body 221 facing the screen body 210, or it can be formed by bending multiple submodules 2221 described in any of the above examples. In this example, the second hole 224 can be used to accommodate functional modules such as a camera module.

[0084] The second hole 224 is filled with a sealant layer 240, and the sealant layer 240 can cover the inner wall surface of the second hole 224. The sealant layer 240 can be a membrane-like structure covering the inner wall surface of the second hole 224. The second hole 224 can also be completely filled with the sealant layer 240. Along the first direction 5a, the thickness of the sealant layer 240 can be no less than the depth of the second hole 224.

[0085] In some examples, a sealant layer 240 is disposed in the first hole 211 and the second hole 224, respectively, and the sealant layer 240 can be used to seal the inner surfaces of the first hole 211, the second hole 224, and the junction of the first hole 211 and the second hole 224. In this example, the sealant layers 240 in the first hole 211 and the second hole 224 can be connected to form a whole, and optionally, the sealant layer 240 in one of the first hole 211 and the second hole 224 can be a film-like structure, and the other can be a sheet-like or block-like structure filling the corresponding position.

[0086] In some examples, the direction from the light emitting surface 212 to the backlight surface 213 is the first direction 5a, that is, the thickness direction of the screen body 210 is the first direction 5a, and the size of the folding portion 222 along the first direction 5a is not less than the size of the first hole 211 along the first direction 5a.

[0087] The dimension of the folded portion 222 along the first direction 5a is not less than the dimension of the first hole 211 along the first direction 5a, which means that the folded portion 222 can pass through the first hole 211, and the end of the folded portion 222 away from the polarizer body 221 can be aligned with the backlight surface 213 of the screen body 210, and the end of the folded portion 222 away from the polarizer body 221 can also protrude outside the backlight surface 213 of the screen body 210. In this example, the portion of the folded portion 222 extending into the first hole 211 can block the flow path of water vapor. By extending the dimension of the folded portion 222 in the first hole 211 along the first direction 5a, the flow path of water vapor can be extended. Under the shielding of the corresponding folded portion 222, the water vapor in the portion of the first hole 211 corresponding to the folded portion 222 is not easy to enter the gap between the polarizer body 221 and the light-emitting surface 212, thereby reducing the black spots in the corresponding portion of the screen body 210.

[0088] In some examples, the polarizer 220 further includes an edge seal 223 , which is connected to an end of the folded portion 222 away from the polarizer body 221 , and the edge seal 223 is at least partially disposed in contact with the backlight surface 213 .

[0089] The sealing in this example can be used to seal the junction between the end of the folded portion 222 away from the polarizer body 221 and the screen body 210. The edge seal 223 in this example can be integrally provided with the folded portion 222, or the edge seal 223 can be separately provided with the folded portion 222 and connected to each other.

[0090] The edge seal 223 is at least partially arranged to fit the backlight surface 213, which means that the edge seal 223 is at least partially in surface contact with the backlight surface 213 to increase the contact area between the edge seal 223 and the backlight surface 213 of the screen body 210. In this example, the edge seal 223 and the folding portion 222 are arranged as an example. The distance between the end of the folding portion 222 away from the polarizer body 221 and the polarizer body 221 can be greater than the size of the first hole 211 along the first direction 5a, and the end of the folding portion 222 away from the polarizer body 221 is bent along the second direction 5b to form the edge seal 223. In this example, the edge seal 223 can be a continuous annular structure arranged along the periphery of the first hole 211, and the edge seal 223 can also be a plurality of point-shaped or strip-shaped structures arranged at intervals on the periphery of the first hole 211. In some examples, the edge seal 223, the folding portion 222 and the polarizer body 221 are integrally arranged, and the position of the polarizer body 221 corresponding to the first hole 211 can be divided to form the submodule 2221 described in any of the above examples, and the submodule 2221 is bent into the first hole 211 to form a plurality of folding portions 222, and the plurality of folding portions 222 are bent at one end away from the polarizer body 221 to form the edge seal 223. Optionally, the sealant layer 240 described in any of the above examples is arranged on the folding portion 222, wherein the sealant layer 240 can extend to the junction of the edge seal 223 and the screen body 210.

[0091] In some examples, the edge seal 223 is arranged in an annular shape along the circumference of the first hole 211; in this example, the edge seal 223 can be arranged in an annular shape around the outer periphery of the first hole 211, so that the edge seal 223 can form an annular sealing area around the outer periphery of the first hole 211. The edge seal 223 can also be used to form a shield and traction on the backlight surface 213 side of the screen body 210 to generate a tendency to block the folding portion 222 from moving toward the light-emitting surface side, thereby reducing the possibility of the polarizer 220 falling off.

[0092] In some examples, the display module 20 further includes a composite film layer 230, and the composite film layer 230 is disposed on the backlight surface 213 of the screen body 210. Optionally, the composite film layer 230 may be a heat dissipation film, and the composite film layer 230 may be made of superclean foam (SCF). On the one hand, the composite film layer 230 can improve the heat dissipation effect of the display module 20, and help to quickly dissipate the heat generated when the panel is working. On the other hand, the composite film layer 230 can be used to block external (background) light to prevent external light from affecting the front display effect of the panel. On the other hand, the composite film layer 230 can be used to enhance the structure of the display module 20 to prevent foreign matter or external force from causing damage to the panel.

[0093] In some examples, a avoidance area 231 is provided on the composite film layer 230, and the orthographic projection of the folding portion 222 on the composite film layer 230 and the orthographic projection of the edge seal 223 on the composite film layer 230 are located in the avoidance area 231. The position of the avoidance area 231 corresponds to the position of the first hole 211. The folding portion 222 and the edge seal 223 are projected uniformly on the composite film layer 230 along the first direction 5a. In the projection plane, the inner contour of the avoidance area 231 is located at the periphery of the edge seal 223, so that the position on the composite film layer 230 corresponding to the edge seal 223 forms an avoidance space, thereby reducing the mutual interference between the composite film layer 230 and the edge seal 223.

[0094] Please refer to Figure 7 and Figure 8 Based on the above display module 20, the present application further proposes an example of a method for preparing the display module 20, the preparation method comprising the following steps:

[0095] S10: providing a screen body 210, wherein the screen body 210 has a light emitting surface 212 and a backlight surface 213 which are arranged opposite to each other.

[0096] like Figure 7 As shown in FIG. 7 a , the light emitting surface 212 and the backlight surface 213 may be two surfaces in the thickness direction of the screen body 210 .

[0097] S20 : ​​a first hole 211 is formed on the light emitting surface 212 of the screen body 210 , and the first hole 211 is extended toward the backlight surface 213 .

[0098] The first hole 211 is a blind hole or a through hole provided on the screen body 210. The first hole 211 penetrates to the light emitting surface 212 and extends in the second direction 5b. When the first hole 211 penetrates to the backlight surface 213, the first hole 211 is a through hole provided on the screen body 210. When the first hole 211 does not penetrate to the backlight surface 213, the first hole 211 may be a blind hole provided on the screen body 210. The first hole 211 in this example may be used to form a space for installing a camera module or other functional components.

[0099] S30: Provide a polarizer 220, wherein the polarizer 220 includes a polarizer body 221 and a folding portion 222, wherein the polarizer body 221 is connected to the light emitting surface 212, the folding portion 222 is connected to a side of the polarizer body 221 facing the screen body 210, and the folding portion 222 is extended into the first hole 211.

[0100] like Figure 7As shown in Figures 7b to 7c, the folding portion 222 is connected to the polarizer body 221 so that the folding portion 222 can form an integral structure with the polarizer body 221. In this example, the folding portion 222 is connected to the side of the polarizer body 221 facing the screen body 210, so that the folding portion 222 forms a protruding structure on the side of the polarizer body 221 facing the screen body 210. The folding portion 222 in this example can be a convex rib protruding from the side of the polarizer body 221 facing the screen body 210, and the folding portion 222 can also be a structure formed by bending a part of the polarizer body 221. The folding portion 222 is used to form a protruding shielding structure on the side of the polarizer body 221 facing the screen body 210, and the folding portion 222 can completely block the entire gap at the junction of the screen body 210 and the light emitting surface 212, and the folding portion 222 can also partially block the gap at the junction of the screen body 210 and the light emitting surface 212. In order to facilitate the molding of the polarizer 220, the folding portion 222 in this example can be a protruding structure formed by partially bending the polarizer body 221 at a position corresponding to the first hole 211. The folding portion 222 is extended into the first hole 211, which means that the folding portion 222 can partially protrude from the first hole 211, and the portion of the folding portion 222 extending into the first hole 211 can be used to form a shield at the junction of the light emitting surface 212 and the polarizer body 221. In this example, when the folded portion 222 extends into the first hole 211, on the one hand, the folded portion 222 can block the water vapor from flowing toward the junction of the light emitting surface 212 and the polarizer body 221, and on the other hand, the folded portion 222 can extend the flow path of the water vapor toward the junction of the light emitting surface 212 and the polarizer body 221, so as to reduce the accumulation of water vapor at the junction of the light emitting surface 212 and the polarizer body 221, reduce the impact of water vapor on the pixel components of the screen body 210, and thereby reduce the failure problem of the pixel components near the first hole 211, thereby reducing the possibility of black spots on the screen body 210 near the first hole 211, which helps to improve the image display quality of the display module 20.

[0101] In this example, a camera module can be installed in the first hole 211, and the folding portion 222 can be arranged on the periphery of the camera module; the folding portion 222 in this example can be used to form a ring structure on the outside of the camera module to block the gap between the camera module and the inner wall surface of the first hole 211, thereby improving the sealing performance of the joint between the light-emitting surface 212 and the polarizer body 221. Optionally, the folding portion 222 can also partially block the gap between the camera module and the inner wall surface of the first hole 211.

[0102] In some examples, the folded portion 222 is at least partially attached to the inner wall of the first hole 211. The folded portion 222 can be at least partially attached to the inner wall of the first hole 211 to reduce the gap between the folded portion 222 and the inner wall of the first hole 211. In this example, the portion of the folded portion 222 extending to the inside of the first hole 211 can be at least partially bonded to the inner wall of the first hole 211 to prevent water vapor from flowing through the gap between the folded portion 222 and the inner wall of the first hole 211 to the junction of the polarizer body 221 and the light emitting surface 212. Optionally, the portion of the folded portion 222 extending to the inside of the first hole 211 can be attached to the inner wall of the first hole 211 to increase the contact area between the folded portion 222 and the inner wall of the first hole 211, further blocking the flow of water vapor.

[0103] In some examples, the direction from the light emitting surface 212 to the backlight surface 213 is the first direction 5 a , and the length of the folded portion 222 along the first direction 5 a is not less than the depth of the first hole 211 along the first direction 5 a .

[0104] The length of the folded portion 222 along the first direction 5a is not less than the depth of the first hole 211 along the first direction 5a, which means that the folded portion 222 can pass through the first hole 211, and the end of the folded portion 222 away from the polarizer body 221 can be aligned with the backlight surface 213 of the screen body 210, and the end of the folded portion 222 away from the polarizer body 221 can also protrude outside the backlight surface 213 of the screen body 210. In this example, the portion of the folded portion 222 extending into the first hole 211 can block the flow path of water vapor. By extending the depth of the folded portion 222 in the first hole 211 along the first direction 5a, the flow path of water vapor can be extended. Under the shielding of the corresponding folded portion 222, the water vapor in the portion of the first hole 211 corresponding to the folded portion 222 is not easy to enter the gap between the polarizer body 221 and the light-emitting surface 212, thereby reducing the black spots at the corresponding portion of the screen body 210.

[0105] In some examples, the folding portion 222 is arranged in an annular shape along the inner wall surface of the first hole 211. In this example, the folding portion 222 can be arranged in an annular shape around the inner wall surface of the first hole 211, so that the folding portion 222 forms an annular blocking area in the first hole 211, increasing the shielding area of ​​the folding portion 222 on the inner wall surface of the first hole 211. Optionally in this example, the folding portion 222 can form a continuous annular structure on the inner side of the first hole 211, and the hollow area formed on the inner side of the folding portion 222 can be used to accommodate functional components such as a camera module.

[0106] like Figure 7As shown in Figure 7c, in some examples, in the above step S30, the polarizer body 221 and the folding portion 222 are integrally arranged, and the portion of the polarizer 220 corresponding to the light emitting surface forms the polarizer body 221, and the position of the polarizer 220 corresponding to the first hole 211 is at least partially bent toward the backlight surface 213 to form the folding portion 222. In this example, the polarizer body 221 and the folding portion 222 are integrally arranged, which means that the polarizer body 221 and the folding portion 222 are an integral structure, and the folding portion 222 is formed by partially bending the portion of the polarizer 220 corresponding to the first hole 211. In this example, the folding portion 222 can be attached to the inner wall surface of the first hole 211 after being bent. Optionally, after the folding portion 222 is bent to form the folding portion 222, a ring-shaped structure can be formed in the first hole 211 to form a ring-shaped blocking structure in the first hole 211. In some examples, after the folded portion 222 is formed by bending, at least one of the thickness and the length of the folded portion 222 at different locations along the circumferential direction of the first hole 211 may be unequal.

[0107] Please refer to Figure 3 , Figure 4 , Figure 7 as well as Fig. 9 In some examples, step S30 includes:

[0108] S31 : forming a cutting line 2222 at a position of the polarizer 220 corresponding to the first hole 211 , wherein the cutting line 2222 separates the position of the polarizer 220 corresponding to the first hole 211 into a plurality of sub-modules 2221 .

[0109] In this example, the part of the polarizer 220 corresponding to the first hole 211 refers to the position on the polarizer 220 corresponding to the first hole 211 projected along the first direction 5a. The cut-off line 2222 can be a continuous straight line, a curve, or a combination of a straight line and a curve. The cut-off line 2222 can be a line formed by a groove formed at a preset position on the polarizer 220. The cut-off line 2222 can also be a broken line. The cut-off line 2222 separates the part of the polarizer 220 corresponding to the first hole 211 to form a plurality of submodules 2221. The plurality of submodules 2221 can be fan-shaped or other polygonal shapes. The shapes and sizes of the plurality of submodules 2221 in this example can be equal or unequal.

[0110] S32 : bending the plurality of submodules 2221 toward the first hole 211 to form a folded portion 222 , and attaching the portion to the light emitting surface 212 to form a polarizer body 221 .

[0111] After the multiple submodules 2221 are bent into the first hole 211, the corresponding parts of the multiple submodules 2221 can form multiple folded parts 222 in the first hole 211. In this example, the multiple folded parts 222 can be attached to the inner wall surface of the first hole 211 respectively to form a sealing structure on the inner wall surface of the first hole 211.

[0112] In this example, the edge seal 223 described in any of the above examples can be provided at the end of the folding portion 222 away from the polarizer body 221. The edge seal 223 can be used to seal the end of the folding portion 222 away from the polarizer body 221 on the one hand, and can be used to form a limit at the end of the folding portion 222 away from the polarizer body 221 on the other hand, so as to reduce the possibility of the folding portion 222 falling off from the first hole 211.

[0113] The number of submodules 2221 in this example is at least two, and the depths of the multiple submodules 2221 in the first hole 211 may be equal or unequal. Optionally, the cut-off line 2222 in this example may separate the portion of the polarizer body 221 corresponding to the first hole 211 to form multiple submodules 2221 of equal area, and the multiple submodules 2221 may be bent into the first hole 211 respectively, so that the multiple submodules 2221 may form multiple folding portions 222 of equal volume or close volume in the first hole 211.

[0114] In this example, a plurality of submodules 2221 are formed by separating the submodules 2221 through the cutting lines 222. When the submodule 2221 is bent to form the folding portion 222, on the one hand, the problem of tearing of the polarizer 220 during the bending process can be reduced, which helps to improve the yield of the display module 20. On the other hand, when the folding portion 222 is bent to form the folding portion 222, the folding portion 222 can maintain a preset thickness and shape in the first hole 211, thereby reducing the deformation of the folding portion 222. On another hand, during the forming process of the folding portion 222, the traction force generated by the folding portion 222 on the polarizer body 221 is relatively reduced, which can reduce the displacement of the polarizer body 221 on the screen body 210, reduce the misalignment of the polarizer 220, and improve the structural stability of the polarizer 220 on the screen body 210.

[0115] Optionally, in this example, the order of step S20, step S31 and step S32 can be adjusted as needed, the first hole 211 can be a through hole that passes through the screen body 210, and the polarizer 220 can be firstly set on the screen body 210, and the above step S31 or the above step S20 can be executed to bend the multiple sub-modules 2221 toward the inside of the first hole 211 to form a folding portion 222.

[0116] See also Fig.10 In some examples, after the above step S32, the preparation method further includes the following steps:

[0117] S33 : filling the first hole 211 with a sealant layer 240 .

[0118] The sealant layer 240 in this example can be used to seal the gap between the folded portion 222 and the inner wall surface of the first hole 211 and / or the light emitting surface 212, so as to reduce the possibility that water vapor affects the screen body 210 through the gap between the folded portion 222 and the inner wall surface of the first hole 211 and / or the light emitting surface 212. The sealant layer 240 can be liquid optical transparent adhesive OCR.

[0119] In some examples, in the above step S33, a sealant layer 240 is provided in the gap between the folding portion 222 and the screen body 210. The sealant layer 240 in this example can be used only to seal the gap between the folding portion 222 and the screen body 210. The gap between the screen body 210 and the folding portion 222 can be a gap between an end of the folding portion 222 away from the polarizer body 221 and the surface of the screen body 210, or a gap between a portion of the folding portion 222 located in the first hole 211 and the inner wall surface of the first hole 211, or a gap between an end of the folding portion 222 close to the light emitting surface 212 and the screen body 210.

[0120] In some examples, in the above step S33, the sealant layer 240 covers the side surface of the folded portion 222 facing away from the inner wall surface of the first hole 211; after the folded portion 222 extends into the first hole 211, the side surface of the folded portion 222 facing the inner wall surface of the first hole 211 can be the outer surface of the folded portion 222, and the side surface of the folded portion 222 opposite to the outer surface can be the inner surface of the folded portion 222, which is attached to the inner wall surface of the first hole 211, and the sealant layer 240 can cover the inner surface of the folded portion 222. The sealant layer 240 in this example can form a film-like structure on the surface of the folded portion 222 to seal the gap between the folded portion 222 and the inner wall surface of the first hole 211. The area of ​​the outer peripheral surface of the membrane structure formed by the sealant layer 240 may be consistent with the area of ​​the inner surface of the folding portion 222; optionally, when the folding portion 222 is formed by bending a plurality of submodules 2221 at the position corresponding to the first hole 211 on the polarizer body 221, the membrane structure formed by the sealant layer 240 may also cover the gap between adjacent folding portions 222. Optionally, in this example, the inner surface of the folding portion 222 may be enclosed to form a hole-like structure, and the hole-like structure enclosed by the inner surface of the folding portion 222 may be coaxially arranged with the first hole 211.

[0121] In some examples, in the above step S33, a second hole 224 is formed at a position of the polarizer body 221 corresponding to the first hole 211, and the folding portion 222 is at least partially disposed at an end of the second hole 224 facing the screen body 210; the sealant layer 240 is filled into the second hole 224; the second hole 224 corresponds to the position of the first hole 211 of the screen body 210, which means that the polarizer body 221 is projected onto the light emitting surface 212 along the first direction 5a, and the second hole 224 at least partially overlaps with the first hole 211.

[0122] The folding portion 222 is at least partially disposed at one end of the second hole 224 facing the screen body 210, which means that the folding portion 222 can extend from the second hole 224 toward the first hole 211 and at least partially extend into the first hole 211, or the folding portion 222 is connected to the side of the polarizer body 221 facing the screen body 210 and extends into the first hole 211. In this example, the folding portion 222 can be a protruding structure protruding from the side of the polarizer body 221 facing the screen body 210, or it can be formed by bending multiple submodules 2221 described in any of the above examples. In this example, the second hole 224 can be used to accommodate functional modules such as a camera module. The second hole 224 is filled with a sealant layer 240, and the sealant layer 240 can cover the inner wall surface of the second hole 224. The sealant layer 240 can be a membrane-like structure covering the inner wall surface of the second hole 224. The second hole 224 can also be completely filled with the sealant layer 240. Along the first direction 5a, the thickness of the sealant layer 240 can be no less than the depth of the second hole 224.

[0123] In some examples, a sealant layer 240 is disposed in the first hole 211 and the second hole 224, respectively, and the sealant layer 240 can be used to seal the inner surfaces of the first hole 211, the second hole 224, and the junction of the first hole 211 and the second hole 224. In this example, the sealant layers 240 in the first hole 211 and the second hole 224 can be connected to form a whole, and optionally, the sealant layer 240 in one of the first hole 211 and the second hole 224 can be a film-like structure, and the other can be a sheet-like or block-like structure filling the corresponding position.

[0124] Please refer again Figure 3 , Figure 4 and Figure 7 In some examples, the cutting line 2222 has two oppositely disposed end portions 3a and a middle portion 3b between the two end portions 3a. Before step S32, the preparation method further includes cutting to form a hollow area 2223 at a position close to the middle portion 3b of at least one submodule 2221.

[0125] The end portion 3a may be the end of the cutting line 2222 along the length direction. The middle portion 3b may be any position between the ends of the cutting line 2222. Optionally, the middle portion 3b may be the middle portion or a position close to the middle portion along the length direction of the cutting line 2222. The hollow area 2223 in this example is arranged at the position of the middle portion 3b of the submodule 2221 close to the cutting line 2222. When the submodule 2221 is bent to form the folded portion 222, the folded portion 222 can form a shielding structure in the first hole 211.

[0126] The hollow area 2223 may be a hollow area on the submodule 2221, and the hollow area 2223 may run through the thickness direction of the submodule 2221. In this example, a local hollow part may be cut at a position near the middle part 3b of the submodule 2221 to remove a part of the position near the middle part 3b of the submodule 2221; optionally, in this example, a broken line may be cut at a region near the middle part 3b of the submodule 2221, and the broken line encloses the hollow area 2223. In this example, the hollow area 2223 may be cut at a position near the middle part 3b of a single submodule 2221, or the hollow area 2223 may be cut at a position near the middle part 3b of each submodule 2221 near the cutting line 2222. The hollow areas 2223 of adjacent submodules 2221 may be connected to each other.

[0127] The hollow area 2223 in this example can form a disconnection portion at the position of the submodule 2221 close to the middle portion 3b. When the submodule 2221 is bent, the hollow area 2223 of the submodule 2221 can be easily disconnected to reduce mutual traction and interference between adjacent submodules 2221.

[0128] In some examples, the hollow area 2223 is located at the junction of multiple submodules 2221. In this example, the hollow area 2223 can form a breakpoint at the junction of adjacent submodules 2221 to reduce the traction between adjacent submodules 2221, thereby reducing the tearing problem caused by the bending of adjacent submodules 2221. Optionally, in this example, taking the multiple submodules 2221 as fan-shaped structures as an example, the hollow area 2223 can form a hollow area at the center of the circle where the multiple submodules 2221 are connected to reduce the mutual traction of the parts of the multiple submodules 2221 close to the center of the circle, and reduce the possibility of damage and deformation when forming the folding portion 222.

[0129] Please refer to Figure 7 and Fig.11 In some examples, after the above step S30, the preparation method further includes the following steps:

[0130] S34: bending one end of the folded portion 222 away from the polarizer body 221 toward the backlight surface 213 to form a sealed edge 223 .

[0131] like Figure 7 As shown in Figures 7c to 7d, the sealing in this example can be used to block the junction between the end of the folding portion 222 away from the polarizer body 221 and the screen body 210. The edge sealing 223 in this example can be integrally provided with the folding portion 222, or the edge sealing 223 can be separately provided with the folding portion 222 and connected to each other.

[0132] In some examples, the edge seal 223 is at least partially attached to the backlight surface 213, and the edge seal 223 is at least partially in surface contact with the backlight surface 213, so as to increase the contact area between the edge seal 223 and the backlight surface 213 of the screen body 210. In this example, the edge seal 223 and the folding portion 222 are integrally arranged as an example, and the distance between the end of the folding portion 222 away from the polarizer body 221 and the polarizer body 221 can be greater than the depth of the first hole 211 along the first direction 5a, and the end of the folding portion 222 away from the polarizer body 221 is bent along the second direction 5b to form the edge seal 223. In this example, the edge seal 223 can be a continuous annular structure arranged along the periphery of the first hole 211, and the edge seal 223 can also be a plurality of point-shaped or strip-shaped structures arranged at intervals on the periphery of the first hole 211. In some examples, the edge seal 223, the folding portion 222 and the polarizer body 221 are integrally arranged, and the position of the polarizer body 221 corresponding to the first hole 211 can be divided to form the submodule 2221 described in any of the above examples, and the submodule 2221 is bent into the first hole 211 to form a plurality of folding portions 222, and the plurality of folding portions 222 are bent at one end away from the polarizer body 221 to form the edge seal 223. Optionally, the sealant layer 240 described in any of the above examples is arranged on the folding portion 222, wherein the sealant layer 240 can extend to the junction of the edge seal 223 and the screen body 210.

[0133] The order of step S34 in this example and step S33 in the above example can be swapped. Step S34 can be performed first to form the edge seal 223 , and then the sealant layer 240 can be formed in the first hole 211 .

[0134] In some examples, the edge seal 223 is arranged in a ring shape along the circumference of the first hole 211 ; in this example, the edge seal 223 can be arranged in a ring shape around the outer periphery of the first hole 211 so that the edge seal 223 can form an annular sealing area on the outer periphery of the first hole 211 .

[0135] Please continue reading Fig.11 In some examples, after step S34, the preparation method further includes:

[0136] S35 : disposing a composite film layer 230 on the backlight surface 213 of the screen body 210 .

[0137] like Figure 7 d and Figure 7 As shown in FIG. 5 , the composite film layer 230 can be a heat dissipation film, and the composite film layer 230 can be made of ultra-clean foam. On the one hand, the composite film layer 230 can improve the heat dissipation effect of the display module 20, which helps to quickly dissipate the heat generated when the panel is working. On the other hand, the composite film layer 230 can be used to block external (background) light to prevent external light from affecting the front display effect of the panel. On the other hand, the composite film layer 230 can be used to enhance the structure of the display module 20 to prevent foreign matter or external force from causing damage to the panel.

[0138] In some examples, a avoidance zone 231 is provided on the composite film layer 230, and the orthographic projection of the folding portion 222 on the composite film layer 230 and the orthographic projection of the edge seal 223 on the composite film layer 230 are located in the avoidance zone 231. The position of the avoidance zone 231 corresponds to the position of the first hole 211. The folding portion 222 and the edge seal 223 are projected uniformly on the composite film layer 230 along the first direction 5aa, and in the projection plane, the inner contour of the avoidance zone 231 is located at the periphery of the edge seal 223, so that the position on the composite film layer 230 corresponding to the edge seal 223 forms an avoidance space, thereby reducing the mutual interference between the composite film layer 230 and the edge seal 223.

[0139] See also Figure 1 Based on the above display module 20, the present application further proposes an example of an electronic device 100, including a housing 10 and a display module 20 as described in any of the above examples, and a screen 210 is connected to the housing 10. The housing 10 may be a shell of the electronic device 100, or the housing 10 may be an external housing 10 of the display module 20. It is understandable that the electronic device 100 may also include other functional modules, and reference may be made to related technologies.
