Display module, manufacturing method thereof, and display device

Abstract

This application discloses a display module and its manufacturing method, as well as a display device, belonging to the field of display technology. The display module includes a display panel, a cover plate, a first support and protection portion, and multiple functional film layers. The display panel includes a panel bending portion, and the bending arc of the panel bending portion is less than 180 degrees. The smaller the bending arc, the smaller the maximum distance between the side of the panel bending portion facing away from the multiple functional film layers and the multiple functional film layers, resulting in a smaller bezel on the side of the display module with the panel bending portion, and an increased screen-to-body ratio. A first support and protection portion is provided on the side of the panel bending portion facing away from the multiple functional film layers, allowing direct assembly onto a support platform of the mid-frame, ensuring that the panel bending portion does not collide with the mid-frame, thus eliminating the need for a large space between the panel bending portion and the mid-frame. Reducing the distance between the panel bending portion and the mid-frame results in a smaller bezel width on the side of the display module with the panel bending portion, further increasing the screen-to-body ratio of the display module.

Description

Display modules and their manufacturing methods, display devices Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel, its manufacturing method, and a display device. Background Technology

[0002] With the development of display technology, the demand for and application scope of display devices are constantly expanding. Currently, in order to achieve a larger screen-to-body ratio and provide users with a better visual experience, narrowing the bezel has become a development trend for display devices.

[0003] A display device typically includes a display module and a frame (often referred to as a mid-frame). The display module includes a display panel. A driver chip and a flexible circuit board are connected to the non-display area of ​​the display panel, and drive signals can be transmitted to the display area of ​​the display panel through the non-display area. By bending the non-display area of ​​the display panel, the driver chip and flexible circuit board are bent to the side of the display panel opposite to the display surface.

[0004] However, the bending part of the display panel has poor impact resistance. In order to protect the display panel, a certain space needs to be reserved between the bending part of the display panel and the middle frame. This space will increase the bezel width of the display module, resulting in a lower screen-to-body ratio of the display module.

[0106] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0107] Please refer to Figures 1 and 2. Figure 1 is a top view of a display module provided in an embodiment of this application, and Figure 2 is a cross-sectional view of the display module shown in Figure 1 at point A-A'. The display module 000 includes: a display panel 100, a cover plate 200, a first support and protection part 300, and multiple functional film layers 400.

[0108] The display panel 100 in the display module 000 includes: a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. That is, the panel bending portion 130 can be located between the first panel portion 110 and the second panel portion 120, and one side of the panel bending portion 130 can be connected to the first panel portion 110, and the other side of the panel bending portion 130 can be connected to the second panel portion 120. The first panel portion 110 has a display surface S1, and the display module 000 can display an image through the display surface S1 of the first panel portion 110.

[0109] It should be noted that, as shown in Figure 2, the cross-sectional shape of the panel bending portion 130 is an arc, and the bending arc α of the panel bending portion 130 is less than 180 degrees. That is, the included angle α between the side of the panel bending portion 130 connecting to the first panel (the location of the starting point of the panel bending portion 130 in cross-section) and the bending axis O of the panel bending portion 130, and the side of the panel bending portion 130 connecting to the second panel portion 120 (the location of the starting point of the panel bending portion 130 in cross-section) and the bending axis O of the panel bending portion 130 is less than 180 degrees.

[0110] In this case, in a direction parallel to the display surface S1 and perpendicular to the bending axis of the panel bending portion 130, the maximum distance r between the edge of the first panel portion 110 connecting the panel bending portion 130 and the panel bending portion 130 is less than the bending radius R of the panel bending portion 130. The relationship between the maximum distance r between the edge of the first panel portion 110 connecting the panel bending portion 130 and the panel bending portion 130 and the bending radius R of the panel bending portion 130 is: r = R(1 - cos(a / 2)). Therefore, the smaller the bending arc 'a' of the panel bending portion 130, the smaller the maximum distance 'r' between the edge of the first panel portion 110 connecting the panel bending portion 130 and the panel bending portion 130, and the smaller the maximum distance between the edge of the panel bending portion 130 and the display surface S1 in the first panel portion 110 in the direction parallel to the first panel portion 110, the smaller the width of the bezel on the side of the display module 000 with the panel bending portion 130, thereby increasing the screen ratio of the display module 000.

[0111] Multiple functional film layers 400 in the display module 000 are stacked between the first panel portion 110 and the second panel portion 120.

[0112] The cover plate 200 in the display module 000 is located on the side of the first panel portion 110 opposite to the plurality of functional film layers 400. The cover plate 200 in the display module 000 may include: a cover plate body 210 covering the first panel portion 110, and a first protrusion 220 connected to the cover plate body 210. Here, the first panel portion 110 can be fitted with the cover plate body 210 in the cover plate 200, so that the cover plate body 210 can protect the side of the first panel portion 110 opposite to the plurality of functional film layers 400. And the first protrusion 220 in the cover plate 200 can cover the panel bending portion 130, that is, in a direction parallel to the display surface S1 of the display panel 100 and perpendicular to the bending axis of the panel bending portion 130, the side of the first protrusion 220 opposite to the cover plate body 210 protrudes from the side of the panel bending portion 130 opposite to the plurality of functional film layers 400. In this way, the first protrusion 220 in the cover plate 200 can protect the side of the panel bend 130 facing the cover plate 200.

[0113] The first support and protection portion 300 in the display module 000 is located at least on the side of the panel bending portion 130 away from the plurality of functional film layers 400, and the first support and protection portion 300 is connected to the first protrusion 220 on the side facing the cover plate 200. That is, the first support and protection portion 300 covers the side of the panel bending portion 130 away from the plurality of functional film layers 400. In this way, the first support and protection portion 300 can protect the panel bending portion 130 from the side away from the first support and protection layer 300, so as to ensure that after the display module 000 is subjected to an impact force, the first support and protection portion 300 can protect the panel bending portion 130 from the side, thereby ensuring that the panel bending portion 130 is not easily damaged.

[0114] In this embodiment, the side of the first support protection part 300 facing away from the first protrusion 220 is used to connect with a support platform in the middle frame. For example, as shown in FIG3, FIG3 is a schematic diagram of a display module and its assembly in this embodiment. The middle frame 010 may include a side plate 011 and a support platform 012 fixedly connected to the side plate 011 on its inner side. The side of the first support protection part 300 in the display module 000 facing away from the first protrusion 220 can be assembled onto the support platform 012.

[0115] It should be noted that when the first support and protection part 300 is not provided in the display module 000, please refer to Figure 4, which is a schematic diagram of a display module without the first support and protection part and its assembly with the middle frame. The first protrusion 220 of the cover plate 200 in the display module 000 needs to be assembled on the support platform 012 in the middle frame 010. In this case, in order to ensure that the panel bending part 130 in the display panel 100 does not collide with the middle frame 010, it is necessary to ensure that the reserved space between the panel bending part 130 and the middle frame 010 is large, resulting in a large distance D1 between the panel bending part 130 and the middle frame 010.

[0116] In this embodiment, after a first support and protection part 300 is provided on the side of the panel bending portion 130 away from the multiple functional film layers 400, the first support and protection part 300 can be directly assembled onto the support platform 012 of the middle frame 010, so that there is a first support and protection part 300 between the panel bending portion 130 and the middle frame 010, so as to ensure that the panel bending portion 130 will not directly collide with the middle frame 010, thereby eliminating the need to reserve a large space between the panel bending portion 130 and the middle frame 010. In this way, the distance D2 between the panel bending portion 130 and the middle frame 010 can be effectively reduced, so that the bezel width on the side of the display module 000 with the panel bending portion 130 is smaller, thereby increasing the screen ratio of the display module 000.

[0117] In summary, the display module provided in this application includes: a display panel, a cover plate, a first support and protection part, and multiple functional film layers. The display panel includes a panel bending portion, and the bending arc of the panel bending portion is less than 180 degrees. The smaller the bending arc, the smaller the maximum distance between the side of the panel bending portion away from the multiple functional film layers and the multiple functional film layers, resulting in a smaller bezel on the side of the display module with the panel bending portion, thereby increasing the screen-to-body ratio of the display module. A first support and protection part is provided on the side of the panel bending portion away from the multiple functional film layers. The first support and protection part can be directly assembled onto the support platform of the middle frame, ensuring that there is a first support and protection part between the panel bending portion and the middle frame. This prevents the panel bending portion from directly colliding with the middle frame, thus eliminating the need for a large space between the panel bending portion and the middle frame. This effectively reduces the distance between the panel bending portion and the middle frame, resulting in a smaller bezel width on the side of the display module with the panel bending portion, further increasing the screen-to-body ratio of the display module.

[0118] In this application, the first support and protection portion 300 is also located on the side of the second panel portion 120 opposite to the plurality of functional film layers 400. In this way, the side of the second panel portion 120 opposite to the plurality of functional film layers 400 can be covered by the first support and protection portion 300, which can protect the second panel portion 120.

[0119] In this embodiment, please refer to FIG5, which is another cross-sectional view of the display module shown in FIG1 at A-A'. The first support and protection part 300 includes: a first barrier 310, a second barrier 320, and a first filler colloid 330.

[0120] The first barrier wall 310 in the first support and protection part 300 is located on the side of the panel bending part 130 away from the multiple functional film layers 400, and there is a first gap K1 between the first barrier wall 310 and the panel bending part 130. The first barrier wall 310 is connected to the first protrusion 220.

[0121] The second barrier 320 in the first support and protection section 300 is located on the side of the second panel section 120 away from the plurality of functional film layers 400, and the extension direction of the second barrier 320 is parallel to the extension direction of the first barrier 310.

[0122] The first filler colloid 330 in the first support and protection part 300 is filled at least in the area between the first retaining wall 310 and the second retaining wall 320.

[0123] It should be noted that the side of the first retaining wall 310 facing away from the first protrusion 220 is substantially flush with the side of the second retaining wall 320 facing away from the second panel portion 120. Before the first filler 330 is filled into the area between the first retaining wall 310 and the second retaining wall 320 and before it cures, the first filler 330 has high fluidity, allowing it to fill the area between the first retaining wall 310 and the second retaining wall 320 through the first gap K1 formed between the first retaining wall 310 and the panel bending portion 130. Thus, after the first filler 330 cures, it ensures that the first filler 330 covers the side of the panel bending portion 130 facing away from the multiple functional film layers 400, and that the first filler 330 remains on the side of the second panel portion 120 facing away from the multiple functional film layers 400. It also ensures that the side of the first filler 330 facing the cover plate 200 is connected to the first protrusion 220. In this way, the first support and protection part 300 can better protect the panel bending part 103 in the display panel 000 through the first filling colloid 330.

[0124] For example, the method of forming the first support protection portion 300 in this application may include the following steps:

[0125] Step S11: A first barrier 310 is formed on the side of the panel bending portion 130 away from the plurality of functional film layers 400. The formed first barrier 310 has a first gap K1 between it and the panel bending portion 130, and the formed first barrier 310 can be connected to the first protrusion 220.

[0126] In this embodiment of the application, as shown in FIG6, FIG6 is another cross-sectional schematic diagram of the display module shown in FIG1 at A-A'. The method of forming the first barrier 310 may include: forming a plurality of first printed strips 311 by multiple 3D printing processes on the side of the panel bending portion 130 away from the plurality of functional film layers 400. Here, one first printed strip 311 can be formed by each 3D printing process. And the plurality of first printed strips 311 formed by multiple 3D printing processes can be stacked in a direction away from the first protrusion 220.

[0127] Therefore, the first barrier 310 includes a plurality of first printed strips 311 stacked in a direction away from the first protrusion 220. For example, as shown in FIG6, a seven-times 3D printing process can be performed on the side of the panel bending portion 130 away from the plurality of functional film layers 400, so that the formed first barrier 310 includes seven first printed strips 311, and the cross-sectional shape of each first printed strip 311 can be a shape similar to a circle or an ellipse.

[0128] It should be noted that the height and width of each of the seven first printing strips 311 formed by the 3D printing process are about 0.2 mm. Therefore, the total height of the first barrier wall 310 composed of the seven first printing strips 311 is about 1.4 mm, so as to ensure that the side of the first barrier wall 310 away from the first protrusion 220 is higher than the side of the second panel 120 away from the first panel 110.

[0129] Step S12: A second barrier 320 is formed on the side of the second panel portion 120 opposite to the plurality of functional film layers 400. The extension direction of the formed second barrier 320 may be parallel to the extension direction of the first barrier 310.

[0130] In this embodiment of the application, as shown in FIG6, the method for forming the second barrier 320 may include: forming at least one second printed strip 321 on the side of the second panel portion 120 opposite to the plurality of functional film layers 400 using at least one 3D printing process. Here, one second printed strip 321 can be formed each time a 3D printing process is used.

[0131] Therefore, the second barrier 320 includes at least one second printing strip 321. Where the second barrier 320 includes multiple second printing strips 321, the multiple second printing strips 321 are stacked in a direction opposite to the multiple functional film layers 400. For example, as shown in FIG6, the second barrier 320 includes one second printing strip 321, and the cross-sectional shape of the second printing strip 321 can be a shape similar to a circle or an ellipse.

[0132] It should be noted that the height and width of the second printing strip 321 formed by the 3D printing process are both about 0.2 mm, so as to ensure that the side of the second retaining wall 320 away from the second panel 120 is basically flush with the side of the first retaining wall 310 away from the first protrusion 220.

[0133] Step S13: Fill the area between the first retaining wall 310 and the second retaining wall 320 with the first filling colloid 330.

[0134] It should be noted that, because the first filler 330 has high fluidity before curing, the openings formed at the ends of the first and second baffles 310 and 320 need to be sealed to ensure that the first filler 330 filling between the first and second baffles 310 and 320 does not overflow. There are several ways to seal the openings formed at the ends of the first and second baffles 310 and 320. This application embodiment will illustrate this with the following two exemplary implementation methods:

[0135] In a first exemplary implementation, auxiliary retaining walls can be separately provided to seal the openings formed at the ends of the first retaining wall 310 and the second retaining wall 320. For example, please refer to Figure 7, which is a bottom view of a first support and protection portion provided in an embodiment of this application. The first support and protection portion 300 may further include a first auxiliary retaining wall 340 and a second auxiliary retaining wall 350. The two ends of the first auxiliary retaining wall 340 are respectively connected to the first end 310 of the first retaining wall 310 and the first end of the second retaining wall 320, and the two ends of the second auxiliary retaining wall 350 are respectively connected to the second end of the first retaining wall 310 and the second end of the second retaining wall 320. A first filling colloid 330 fills at least the area enclosed by the first retaining wall 310, the second retaining wall 320, the first auxiliary retaining wall 340, and the second auxiliary retaining wall 350.

[0136] Thus, since the first auxiliary baffle 340, first baffle 310, second auxiliary baffle 350, and second baffle 320 in the first support and protection part 300 are connected end to end, they can form an annular baffle with only one opening, and this opening is located on the side of the annular baffle away from the cover plate 200. Therefore, by injecting liquid first filler 330 through the opening on the side of the annular baffle away from the cover plate 200, and after the liquid first filler 330 fills the area enclosed by the annular baffle, the first filler 330 can be cured to obtain the first support and protection part 300 for protecting the panel bending part 130.

[0137] For example, before filling the area between the first barrier wall 310 and the second barrier wall 320 with the first filler colloid 330, that is, before step S13, the method of forming the first barrier wall 310 further includes:

[0138] Step S14: Form a first auxiliary retaining wall 340 for connecting the first end of the first retaining wall 310 and the first end of the second retaining wall 320.

[0139] Step S15: Form a second auxiliary retaining wall 350 for connecting the first end of the first retaining wall 310 and the second end of the second retaining wall 320.

[0140] In this embodiment, both the first auxiliary retaining wall 340 and the second auxiliary retaining wall 350 can be obtained by 3D printing. For example, in forming the first auxiliary retaining wall 340, multiple 3D printing processes can be used, so that the two ends of the 3D-printed first auxiliary retaining wall 340 can be connected to the first ends of the first retaining wall 310 and the second retaining wall 320, respectively. Similarly, in forming the second auxiliary retaining wall 350, multiple 3D printing processes can be used, so that the two ends of the 3D-printed second auxiliary retaining wall 350 can be connected to the second ends of the first retaining wall 310 and the second retaining wall 320, respectively. Therefore, in this embodiment, steps S11, S12, S14, and S15 can form an annular retaining wall composed of the first auxiliary retaining wall 340, the first retaining wall 310, the second auxiliary retaining wall 350, and the second retaining wall 320.

[0141] In this case, the method of filling the first filler colloid 330 in step S13 above may include filling the area enclosed by the first barrier wall 310, the second barrier wall 320, the first auxiliary barrier wall 340 and the second auxiliary barrier wall 350 with the first filler colloid 330.

[0142] In this embodiment, a highly fluid colloid can be injected into the area enclosed by the first auxiliary barrier 340, the first barrier 310, the second auxiliary barrier 350, and the second barrier 320 (i.e., the area enclosed by the annular barrier). For example, the colloid can be a low-viscosity adhesive with a viscosity of less than 200 centipoise and high fluidity. After ensuring that the highly fluid colloid can completely fill the area enclosed by the annular barrier, the colloid within the area enclosed by the annular barrier can be cured to obtain the first filling colloid 330.

[0143] It should be noted that after the colloid in the area enclosed by the annular retaining wall is cured, the flatness of the first filling colloid 330 on the side opposite to the cover plate 200 is usually low. To ensure high stability in the subsequent connection between the first filling colloid 330 and the support platform in the middle frame, after filling the area between the first retaining wall 310 and the second retaining wall 320 with the first filling colloid 330, that is, after step S13, the method for forming the first retaining wall 310 further includes:

[0144] Step S16: Grind the side of the first filling colloid 330 away from the cover plate 200.

[0145] In this embodiment, a milling and grinding process can be used to grind the side of the first filling colloid 330 away from the cover plate 200 to ensure that the flatness of the side of the first filling colloid 330 away from the cover plate 200 is high, thereby ensuring that the subsequent connection between the first filling colloid 330 and the support platform in the middle frame is more stable.

[0146] A second exemplary implementation can utilize the second support and protection portion 500 in the display module 000 to seal the openings formed at the end positions of the first barrier wall 310 and the second barrier wall 320. For example, please refer to Figures 8 and 9. Figure 8 is a top view of another display module provided in this embodiment, and Figure 9 is a cross-sectional schematic diagram of the display module shown in Figure 8 at point B-B'. The display module 000 further includes: a second support and protection portion 500, which is disposed at least around the outer surface of the undistributed panel bending portions 130 in the plurality of functional film layers 400. The cover plate 200 also includes: a second protrusion 230 connected to the cover plate body 210, the second protrusion 230 protruding outward relative to the edge of the first panel portion 110 not connected to the panel bending portion 130. The second support and protection portion 500 is connected to the second protrusion 230 on the side facing the cover plate 200.

[0147] In this case, the display module 000 can protect the side of the distributed panel bending portion 130 in the display module 000 through the first support protection portion 400, and the display module 000 can also protect the other sides of the non-distributed panel bending portion 130 in the display module 000 through the second support protection portion 500.

[0148] It should be noted that the display module 000 is typically rectangular. The panel bending portion 130 in the display module 000 can be located on the lower side of the display module 000, while there are no panel bending portions 130 on the left, top, or right sides of the display module 000. Therefore, the first support and protection portion 400 can be located at the lower border of the display module 000, while the second support and protection portion 500 can be located at the left, top, and right borders of the display module 000. Here, by directly assembling the first support and protection portion 400 with the support platform in the middle frame, the distance between the panel bending portion 130 and the middle frame in the display module 000 can be reduced, thereby ensuring a narrower lower border for the display module 000. Similarly, by assembling the second support protection unit 500 directly with the support platform in the middle frame, the distance between the outer side of the undistributed panel bending portion 130 in the multiple functional film layers 400 of the display module 000 and the middle frame can be reduced, thereby ensuring that the left, top, and right bezels of the display module 000 are all relatively narrow. In this way, the screen-to-body ratio of the display module 000 can be further improved.

[0149] In this embodiment, the multiple functional film layers 400 include a metal support layer 410. A second support and protection portion 500 is also located on the side of the metal support layer 410 facing away from the cover plate 200. Thus, one end of the second support and protection portion 500 is connected to the first end of the first barrier wall 310 and the first end of the second barrier wall 320, respectively, and the other end of the second support and protection portion 500 is connected to the second end of the first barrier wall 310 and the second barrier wall 320, respectively. In this way, the second support and protection portion 500 can be used to seal the openings formed at the ends of the first barrier wall 310 and the second barrier wall 320, ensuring that the first filler colloid 330 before curing does not overflow from the openings formed at the ends of the first barrier wall 310 and the second barrier wall 320.

[0150] It should be noted that when the display module 000 includes the second support and protection part 500, the structure of the second support and protection part 500 can be varied. This application embodiment will illustrate the following two possible cases:

[0151] For the first possible scenario, please refer to Figure 10, which is another cross-sectional view of the display module at B-B' shown in Figure 8. The second support and protection part 500 includes: a third baffle 510, a fourth baffle 520, and a second filler colloid 530.

[0152] The third baffle 510 is disposed around the outer side of the undistributed panel bending portion 130 among the multiple functional film layers 400, and a second gap K2 exists between the third baffle 510 and the multiple functional film layers 400. The third baffle 510 is connected to the second protrusion 230. The fourth baffle 520 is located on the side of the metal support layer 410 away from the cover plate 200, and the extending direction of the fourth baffle 520 is parallel to the extending direction of the third baffle 510. The second filling colloid 530 fills at least the area between the third baffle 510 and the fourth baffle 520.

[0153] It should be noted that the side of the third retaining wall 510 facing away from the second protrusion 230 is basically flush with the side of the fourth retaining wall 520 facing away from the metal support layer 410. Before the second filler colloid 530 is filled into the area between the third retaining wall 510 and the fourth retaining wall 520 and before it cures, the second filler colloid 530 has high fluidity, allowing it to fill the area between the third retaining wall 510 and the fourth retaining wall 520 through the second gap K2 formed between the third retaining wall 510 and the multiple functional film layers 400. Thus, after the second filler colloid 530 cures, it ensures that the second filler colloid 530 can cover the outer side of the undistributed panel bending portion 130 among the multiple functional film layers 400, and that the second filler colloid 530 is still located on the side of the metal support layer 410 facing away from the cover plate 200, while also ensuring that the side of the second filler colloid 530 facing the cover plate 200 is connected to the second protrusion 230. Thus, the second support and protection part 500 can better protect the outer side of the undistributed panel bending part 130 in the display panel 000 through the second filling colloid 530.

[0154] In the embodiments of this application, the second support and protection part 500 and the first support and protection part 300 can be formed simultaneously or separately. Therefore, the embodiments of this application will be described using the following two forming methods as examples.

[0155] In the first method of forming the second support and protection portion 500, where the second support and protection portion 500 is formed separately from the first support and protection portion 300, the method of forming the second support and protection portion 500 may include the following steps:

[0156] Step S21: Form a third barrier 510. The formed third barrier 510 is disposed around the outer side of the undistributed panel bending portion 130 among the plurality of functional film layers 400, and there is a second gap K2 between the formed third barrier 510 and the plurality of functional film layers 400. The formed third barrier 510 is connected to the second protrusion 230.

[0157] In this embodiment of the application, as shown in FIG11, FIG11 is another cross-sectional schematic diagram of the display module at B-B' shown in FIG8. The method for forming the third barrier 510 may include: forming a plurality of third printed strips 511 by multiple 3D printing processes on the outer side of the panel bending portion 130 not distributed in the plurality of functional film layers 400. Here, one third printed strip 511 can be formed by each 3D printing process. And the plurality of third printed strips 511 formed by multiple 3D printing processes can be stacked in a direction away from the second protrusion 230.

[0158] Therefore, the third barrier 510 includes a plurality of third printed strips 511 stacked in a direction away from the second protrusion 230. For example, as shown in FIG11, a 3D printing process of seven times can be performed around the outer side of the undistributed panel bending portion 130 in the plurality of functional film layers 400, so that the formed third barrier 510 includes seven third printed strips 511, and the cross-sectional shape of each third printed strip 511 can be a shape similar to a circle or an ellipse.

[0159] It should be noted that the height and width of each of the seven third printing strips 511 formed by the 3D printing process are about 0.2 mm. Therefore, the total height of the third barrier wall 510 composed of the seven third printing strips 511 is about 1.4 mm, so as to ensure that the side of the third barrier wall 510 away from the second protrusion 230 is higher than the side of the metal support layer 410 away from the cover plate 200.

[0160] Step S22: Forming a fourth retaining wall 520. The fourth retaining wall 520 is located on the side of the metal support layer 410 away from the cover plate 200, and the extension direction of the fourth retaining wall 520 is parallel to the extension direction of the third retaining wall 510.

[0161] In this embodiment of the application, as shown in FIG11, the method for forming the fourth retaining wall 520 may include: forming multiple fourth printed strips 521 on the side of the metal support layer 410 facing away from the cover plate 200 using multiple 3D printing processes. Here, one fourth printed strip 521 can be formed by each 3D printing process.

[0162] Therefore, the fourth barrier 520 includes a plurality of fourth printing strips 521, which are stacked in a direction away from the cover plate 200. For example, as shown in FIG11, the fourth barrier 520 includes two fourth printing strips 521, and the cross-sectional shape of the fourth printing strips 521 can be similar to a circle or an ellipse.

[0163] It should be noted that the height and width of the fourth printing strip 521 formed by the 3D printing process are both about 0.2 mm. Therefore, the total height of the fourth barrier wall 520 composed of the two fourth printing strips 521 is about 0.4 mm, so as to ensure that the side of the fourth barrier wall 520 away from the cover plate 200 is basically flush with the side of the third barrier wall 510 away from the second protrusion 230.

[0164] Step S23: Fill the area between the third retaining wall 510 and the fourth retaining wall 520 with the second filler colloid 530.

[0165] It should be noted that when the second support and protection part 500 and the first support and protection part 300 are formed separately, in order to ensure that the second filling colloid 530 does not overflow, it is also necessary to use auxiliary baffles to seal the openings formed at both ends of the second support and protection part 500. For details, please refer to the relevant content in the aforementioned embodiments, which will not be repeated here. In this case, the first filling colloid 330 in the first support and protection part 300 can be formed after the second support and protection part 500 is formed. Furthermore, after the second support and protection part 500 is formed, its two ends can respectively seal the openings formed at the ends of the first baffle 310 and the second baffle 320, ensuring that the first filling colloid 330 will not overflow during the subsequent formation of the first filling colloid 330 between the first baffle 310 and the second baffle 320.

[0166] It should also be noted that after filling the area between the third retaining wall 510 and the fourth retaining wall 520 with the second filler 530, the side of the second filler 530 facing away from the cover plate 200 can be ground flat to ensure that the second filler 530 can be more stably assembled on the support platform of the middle frame.

[0167] In the second method of formation, where the second support protection part 500 and the first support protection part 300 are formed simultaneously, the method of forming the first support protection part 300 and the second support protection part 500 may include the following steps:

[0168] Step S31: Multiple first annular printed strips are formed using a multi-stage 3D printing process to obtain a connected first barrier wall 310 and a third barrier wall 510. The first barrier wall 310 is located on the side of the panel bending portion facing away from the multiple functional film layers 400, and the third barrier wall 510 is arranged around the outer surface of the multiple functional film layers 400. A first gap K1 exists between the first barrier wall 310 and the panel bending portion 130, and the first barrier wall 310 can be connected to the first protrusion 220. A second gap K2 exists between the third barrier wall 510 and the multiple functional film layers 400, and the third barrier wall 510 is connected to the second protrusion 230.

[0169] In the embodiments of this application, as shown in Figures 6 and 11, each 3D printing process forms a first annular printing strip, which includes a first printing strip 311 belonging to the first barrier 310 and a third printing strip 511 belonging to the third barrier 510.

[0170] In this configuration, the first barrier 310 includes a plurality of first printing strips 311 stacked in a direction away from the first protrusion 220, and the third barrier 510 includes a plurality of third printing strips 511 stacked in a direction away from the second protrusion 230. Furthermore, within the same first annular printing strip, the two ends of the first printing strip 311 can be connected to the two ends of the third printing strip 511, respectively. Therefore, the plurality of first printing strips 311 in the first barrier 310 can correspond one-to-one with the plurality of third printing strips 511 in the third barrier 510. And the two ends of the first printing strip 311 can be connected to the two ends of the corresponding third printing strip 511, respectively.

[0171] For example, as shown in Figures 6 and 11, seven first annular printing strips can be formed by performing seven 3D printing processes around the outer surface of multiple functional film layers 400, and the cross-sectional shape of each first annular printing strip can be similar to a circle or an ellipse.

[0172] It should be noted that the seven first annular printing strips are formed by seven 3D printing processes, and the height and width of each first annular printing strip are about 0.2 mm. Therefore, the total height of the first barrier wall 310 and the third barrier wall 510 formed by the seven first annular printing strips is about 1.4 mm, so as to ensure that the side of the first barrier wall 310 away from the first protrusion 220 is higher than the side of the second panel 120 away from the first panel 110, and the side of the third barrier wall 510 away from the second protrusion 230 is higher than the side of the metal support layer 410 away from the cover plate 200.

[0173] Step S32: At least one fourth printed strip 521 is formed using at least one 3D printing process. The formed fourth printed strip 521 may be located on the side of the metal support layer 410 away from the cover plate 200.

[0174] It should be noted that, due to the panel bending portion 130 in the display module 000, the side of the second panel portion 120 facing away from the first panel portion 110 will be higher than the side of the metal support layer 410 facing away from the cover plate 200. Therefore, at least one 3D printing process can be used to form at least one fourth printing strip 521 on the side of the metal support layer 410 facing away from the cover plate 200. This fourth printing strip 521 can then be positioned so that the side of the second panel portion 120 facing away from the first panel portion 110 is substantially flush with the side of the second panel portion 120 facing away from the first panel portion 110, facilitating subsequent smooth 3D printing.

[0175] Here, at least one fourth printed strip 521 formed by at least one 3D printing process belongs to the fourth retaining wall 520. For example, as shown in Figure 11, a fourth printed strip 521 belonging to the fourth retaining wall 520 is first formed by one 3D printing process, and the cross-sectional shape of the fourth printed strip 521 can be a similar circular or elliptical shape, and the height and width of the fourth printed strip 521 are both about 0.2 mm.

[0176] Step S33: At least one second annular printed strip is formed using at least one 3D printing process to obtain a connected second barrier wall 320 and a fourth barrier wall 520. The formed second barrier wall 320 is located on the side of the second panel portion 120 opposite to the plurality of functional film layers 400, and the formed fourth barrier wall 520 is located on the side of the metal support layer 410 opposite to the cover plate 200. The extension direction of the formed second barrier wall 320 may be parallel to the extension direction of the first barrier wall 310, and the extension direction of the formed fourth barrier wall 520 may be parallel to the extension direction of the third barrier wall 510.

[0177] In this embodiment of the application, as shown in Figures 6 and 11, each second annular printing strip formed in each 3D printing process includes: a second printing strip 321 belonging to the second baffle 320, and a fourth printing strip 521 belonging to the fourth baffle 520. At least one fourth printing strip 521 formed in step S32 also belongs to the fourth baffle 520. Here, after the first 3D printing process, the second printing strip 321 in the formed second annular printing strip can be located on the side of the second panel portion 120 facing away from the first panel portion 110; the fourth printing strip 521 in the formed second annular printing strip can be located on the side of the at least one fourth printing strip 521 formed in step S32 facing away from the metal support layer 410.

[0178] In this configuration, the second barrier 320 includes at least one second printed strip 321. The fourth barrier 520 includes a plurality of fourth printed strips 521 stacked in a direction away from the metal support layer 410. The two ends of the outermost second printed strip 321 of the at least one second printed strip 321 are respectively connected to the two ends of the outermost fourth printed strip 521 of the plurality of fourth printed strips 520.

[0179] For example, as shown in Figures 6 and 11, a second annular printing strip is formed using a single 3D printing process. Thus, the second barrier 320 includes one second printing strip 321, and the fourth barrier 520 includes two fourth printing strips 521. The cross-sectional shapes of the second printing strip 321 and the fourth printing strip 521 can both be similar to circular or elliptical shapes.

[0180] It should be noted that a second annular printing strip is formed through a single 3D printing process. The height and width of the second annular printing strip are both approximately 0.2 mm. Therefore, the total height of the second barrier wall 320 formed by the second annular printing strip is approximately 0.2 mm. The total height of the second annular printing strip and the fourth barrier wall 520 formed by the fourth printing strip 521 in step S32 is approximately 0.4 mm. Furthermore, the sides of the second barrier wall 320 and the fourth barrier wall 520 that are away from the cover plate 200 are basically flush.

[0181] It should also be noted that the first retaining wall 310, the second retaining wall 320, the third retaining wall 510 and the fourth retaining wall 520 are basically flush with the side away from the cover plate 200.

[0182] Step S34: Fill the annular region between the connected first retaining wall 310 and the third retaining wall 510, and between the connected second retaining wall 320 and the fourth retaining wall 520 with colloid to obtain the connected first filling colloid 330 and the second filling colloid 530.

[0183] In this embodiment, a highly fluid colloid can be injected into the annular region between the connected first and third baffles 310 and the connected second and fourth baffles 320. For example, the colloid can be a low-viscosity adhesive with a viscosity of less than 200 centipoise and high fluidity. After ensuring that the highly fluid colloid can fill the area enclosed by the annular region, the colloid within the area enclosed by the annular region can be cured, thereby obtaining the connected first filler colloid 330 and second filler colloid 530. Here, since the first filler colloid 330 and the second filler colloid 530 are cured, the two ends of the first filler colloid 330 located between the first baffle 310 and the second baffle 320 can be connected to the two ends of the second filler colloid 530 located between the third baffle 510 and the fourth baffle 520, respectively.

[0184] It should be noted that after obtaining the first filler 330 and the second filler 530, the sides of the first filler 330 and the second filler 530 facing away from the cover plate 200 can also be ground flat simultaneously to ensure that the first filler 330 and the second filler 530 can be more stably assembled on the support platform of the middle frame. In this case, since the side of the first filler 330 facing away from the cover plate 200 and the side of the second filler 530 facing away from the cover plate 200 are ground flat simultaneously, the side of the first filler 330 facing away from the cover plate 200 can be flush with the side of the second filler 530 facing away from the cover plate 200.

[0185] The second possible scenario is illustrated in Figure 12, which is another cross-sectional view of the display module shown in Figure 8 at point B-B'. The second support and protection unit 500 includes: a fifth print strip 540, at least one sixth print strip 550, and at least one seventh print strip 560.

[0186] In this configuration, the fifth printing strip 540 and at least one sixth printing strip 550 are stacked in a direction away from the second protrusion 230, and the fifth printing strip 540 and at least one seventh printing strip 560 are arranged sequentially in a direction parallel to the cover plate 200. In this configuration, at least one sixth printing strip 550 contacts the outer surface of the undistributed panel bending portion 130 in the plurality of functional film layers 400, and at least one seventh printing strip 560 is distributed on the side of the metal support layer 410 away from the cover plate 200.

[0187] For example, the second support and protection section 500 includes a fifth printed strip 540, three sixth printed strips 550, and two seventh printed strips 560, with the fifth printed strip 540 connecting the three sixth printed strips 550 and the two seventh printed strips 560. The three sixth printed strips 550 contact the outer surface of the undistributed panel bending portion 130 in the plurality of functional film layers 400, and the two seventh printed strips 560 are distributed on the side of the metal support layer 410 facing away from the cover plate 200.

[0188] It should be noted that when the second support protection part 500 is connected to the first support protection part 300, the first baffle 310 is connected to at least the fifth printing strip 540 and three sixth printing strips 550, and the second baffle 320 is connected to at least the outermost seventh printing strip 560. This allows the openings formed at the ends of the first baffle 310 and the second baffle 320 to be sealed, forming an annular baffle with only one opening, located on the side of the annular baffle away from the cover plate 200. Therefore, by injecting liquid first filler 330 through the opening on the side of the annular baffle away from the cover plate 200, and after the liquid first filler 330 fills the area enclosed by the annular baffle, curing the first filler 330 yields the first support protection part 300 for protecting the panel bending portion 130.

[0189] For example, the method of forming the second support protection part 500 in this application may include: forming a fifth printing strip 540, at least a sixth printing strip 550 and at least a seventh printing strip 560 by using multiple 3D printing processes.

[0190] Here, at least one sixth printing strip 550 and a fifth printing strip 540 can be printed sequentially in a direction away from the second protrusion 230 using 3D printing technology; then, at least one seventh printing strip 560 connected to the fifth printing strip 540 can be printed in a direction parallel to the cover plate 200 using 3D printing technology.

[0191] For example, as shown in Figure 12, when the second support protection part 500 includes three sixth printed strips 550, the cross-sectional shape of each sixth printed strip 550 can be a shape similar to a circle or an ellipse. The cross-sectional shape of the fifth printed strip 540 in the second support protection part 500 can also be a shape similar to a circle or an ellipse. When the second support protection part 500 includes two seventh printed strips 560, the seventh printed strip 560 furthest from the fifth printed strip 540 (i.e., the outermost seventh printed strip 560) can be printed first using 3D printing technology, with a certain gap between the seventh printed strip 560 and the fifth printed strip 540; then, a new seventh printed strip 560 can be printed in the gap between the fifth printed strip 540 and this seventh printed strip 560 using 3D printing technology. Therefore, the cross-sectional shape of the outermost seventh printing strip 560 among the two seventh printing strips 560 can be a shape similar to a circle or an ellipse, while the cross-sectional shape of the seventh printing strip 560 between the outermost seventh printing strip 560 and the fifth printing strip 540 is an irregular shape, and the two sides of the middle seventh printing strip 560 are respectively attached to the outermost seventh printing strip 560 and the fifth printing strip 540.

[0192] It should be noted that in the above-described 3D printing process, a high-viscosity adhesive with a viscosity of 2000 centipoise and low flowability can be used as the printing material to ensure that a printed strip of a specific shape can be quickly obtained after 3D printing. Furthermore, to ensure good stability of the printed strip formed by the 3D printing process, the printed strip can be cured after it has been formed. For example, it can be cured by irradiating the printed strip with ultraviolet light with a wavelength of 356 nanometers.

[0193] The above embodiments illustrate various possible implementations of the first support protection part 300 and the second support protection part 500 in the display module 000. The following embodiments, based on the first support protection part 300 and the second support protection part 500 in the display module 000, describe other features of the display module 000:

[0194] Please refer to Figure 13, which is a cross-sectional schematic diagram of a display module provided in an embodiment of this application. The display module 000 may further include a third filler 600. The third filler 600 is located within the accommodating space formed by the side of the plurality of functional film layers 400 facing the panel bending portion 130 and the panel bending portion 130, and the third filler 600 is connected to the side of the panel bending portion 130 facing the plurality of functional film layers 400. Thus, the third filler 600 located within the accommodating space can strengthen the panel bending portion 130 in the display panel 100, thereby protecting the panel bending portion 130 from damage.

[0195] In this configuration, the first support and protection portion 300 and the third filler 600 are incorporated into the display module 000. Through their combined action, the panel bending portion 130 in the display panel 100 can be protected. Therefore, after assembling this display module 000 onto the mid-frame of the display device, even if the mid-frame deforms due to impact, the first support and protection portion 300 ensures a low probability of collision between the panel bending portion 130 and the mid-frame, and the third filler 600 prevents the panel bending portion 130 from deforming towards the multiple functional film layers 400. This ensures that the panel bending portion 130 in the display module 000 is less susceptible to damage, enhances its impact resistance, and reduces the probability of display defects in the display panel 100.

[0196] It should be noted that the third filler 600 can also contact the side of the multiple functional film layers 400 facing the panel bending portion 130. That is, the third filler 600 can completely fill the accommodating space formed by the side of the multiple functional film layers 400 facing the panel bending portion 130 and the panel bending portion 130 itself, preventing the panel bending portion 130 from deforming in the direction of the multiple functional film layers 400, further enhancing the impact resistance of the panel bending portion 130. Furthermore, after the third filler 600 completely fills the accommodating space, it can also prevent air bubbles from forming in the accommodating space during the subsequent formation of the first filler 330 before curing, thus avoiding a decrease in the impact resistance of the first support and protection portion 300. Therefore, the third filler colloid 600 completely fills the accommodating space, further reducing the probability of collision between the panel bending portion 130 and the middle frame, ensuring that the panel bending portion 130 in the display module 000 is not easily damaged, enhancing the impact resistance of the panel bending portion 130, and making the probability of display defects in the display panel 100 lower.

[0197] In this application, to ensure that the third filler colloid 600 completely fills the accommodating space, a novel curable and expandable adhesive material can be used. The third filler colloid 600 using this novel adhesive material can cure under the irradiation of the first light, preventing it from flowing freely. Furthermore, the third filler colloid 600 using this novel adhesive material can expand under the irradiation of the second light, allowing it to further cure while completely filling the accommodating space. Compared to the traditional method of moisture curing during the further curing process of adhesive materials, the time required for further curing using the second light irradiation method of this novel adhesive material is significantly reduced, greatly improving the manufacturing efficiency of the display module 000.

[0198] It should also be noted that the multiple functional film layers 400 further include: at least two first functional film layers distributed on the side of the first panel portion 110 opposite to the cover plate 200, at least one second functional film layer distributed on the side of the second panel portion 120 facing the first panel portion 110, and a support column 440 for connecting the first functional film layers and the second functional film layers. As shown in FIG13, the first functional film layer includes a metal support layer 410 and a first support layer 420, and the metal support layer 410 is located on the side of the first support layer 420 opposite to the first panel portion 110, and the second functional film layer includes a second support layer 430. Therefore, the two sides of the support column 440 can be connected to the metal support layer 410 and the second support layer 430 respectively. The first support layer 420 and the metal support layer 410 can be used to support the first panel portion 110, the second support layer 430 can be used to support the second panel portion 120, and the support column 440 can be used to bond the metal support layer 410 and the second support layer 430 and support the metal support layer 410 and the second support layer 430.

[0199] For example, the method of forming the third filler colloid 600 in this application may include:

[0200] Step S51: Before bending the panel bending portion 130, apply optical adhesive G to the back side of the panel bending portion 130. As shown in Figure 14, Figure 14 is a schematic diagram of applying optical adhesive G to the back side of the panel bending portion according to an embodiment of this application. The optical adhesive G is applied in the groove between the first functional film layer 420 and the second functional film layer 430, so that the optical adhesive G does not flow freely on the back side of the panel bending portion.

[0201] Step S52: Irradiate the optical adhesive with the first light to cure it, so as to prevent the optical adhesive from flowing freely during the subsequent bending process.

[0202] Step S53: The panel bending portion 130 is bent so that the cured adhesive is distributed within the accommodating space. In this case, the cured adhesive is connected to at least one side of the panel bending portion 130 facing the plurality of functional film layers 400.

[0203] Step S54: The optical adhesive distributed in the accommodating space is irradiated with a second light, causing the optical adhesive to expand and come into contact with the side of the multiple functional film layers 400 facing the panel bending portion 130, so as to obtain the third filling adhesive 600.

[0204] Optionally, the optical adhesive G can have a viscosity of 40,000 to 50,000 centipoise, a thixotropic index of 4.1 to 5, a Young's modulus of 1.6 to 2.3 billion Pascals after curing, and a material expansion rate of 6% to 59%. This optical adhesive G can be pre-cured under a first light source with a wavelength of 345 nm to 385 nm, and further cured under a second light source with a wavelength of 450 nm to 490 nm. Simultaneously, under the second light source, the optical adhesive G will expand.

[0205] In this embodiment, please refer to Figure 15, which is a cross-sectional schematic diagram of another display module provided in this embodiment. The support pillar 440 in the display module 000 can be connected to the third filler 600, and the material of the support pillar 440 can be the same as the material of the third filler 600. In this case, the support pillar 440 and the third filler 600 can be formed simultaneously in a single process, thereby simplifying the manufacturing process of the display module 000.

[0206] For example, please refer to Figure 16, which is a schematic diagram of a third filling layer and a support pillar formed in one step according to an embodiment of this application. While applying adhesive to the back of the panel bending portion 130 to form the third filling adhesive 600, a layer of adhesive can also be applied to the side of the metal support layer 410 facing away from the cover plate 200, and to the side of the metal support layer 410 and the first support layer 420 facing the panel bending portion 130. In this way, the third filling layer 600 and the support pillar 440 can be formed in one step after the panel is bent. There will be no gaps between the support pillar 440 and the metal support layer 410 and the second support layer 430. The third filling adhesive 600 can completely fill the accommodating space, ensuring that the panel bending portion 130 in the display module 000 is not easily damaged, enhancing the impact resistance of the panel bending portion 130, and reducing the probability of display defects in the display panel 100.

[0207] Here, in order to ensure that the adhesive applied to the gaps in the membrane layer where the support column 440 is located does not flow freely, a high-viscosity adhesive with poor flowability can be selected.

[0208] In this embodiment, referring to FIG13, the display module further includes an anti-reflection layer 700 located between the first panel portion 110 and the cover plate 200. For example, the anti-reflection layer 700 can be a color filter or a circular polarizer. The anti-reflection layer 700 reduces the reflectivity of the display module 000 to ambient light, resulting in better display performance. The first filler 330 in the first support and protection portion 300 can also fill the gap between the first panel portion 110 and the cover plate 200, and the portion of the first filler 330 filling the gap between the first panel portion 110 and the cover plate 200 can contact the side of the anti-reflection layer 700.

[0209] It should be noted that, in this embodiment, a protective layer can also be provided on the side of the panel bending portion 130 that is away from the multiple functional film layers 400. This protective layer is connected to the panel bending portion 130 to further protect the panel bending portion 130. Of course, the protective layer may not be provided on the side of the panel bending portion 130 that is away from the multiple functional film layers 400. In this case, the first filling colloid 330 in the first support protection portion 300 can directly contact the side of the panel bending portion 130 that is away from the multiple functional film layers 400, thereby further improving the screen ratio of the display module 000.

[0210] In this embodiment, a pendulum test can be used to test the impact resistance of the panel bending portion 130 in the display module 000 equipped with the first support protection part 300 and the third filler colloid 600, and to test the impact resistance of the panel bending portion in the display module 000 without the first support protection part and the third filler colloid. It was found that the panel bending portion 130 in the display module 000 equipped with the first support protection part 300 and the third filler colloid 600 can withstand an impact strength of 80.4 millijoules, while the panel bending portion in the display module 000 without the first support protection part and the third filler colloid can only withstand an impact strength of 2.1 millijoules. Therefore, the first support protection part 300 and the third filler colloid 600 can provide better protection for the panel bending portion 130 in the display module 000.

[0211] In summary, the display module provided in this application includes: a display panel, a cover plate, a first support and protection part, and multiple functional film layers. The display panel includes a panel bending portion, and the bending arc of the panel bending portion is less than 180 degrees. The smaller the bending arc, the smaller the maximum distance between the side of the panel bending portion away from the multiple functional film layers and the multiple functional film layers, resulting in a smaller bezel on the side of the display module with the panel bending portion, thereby increasing the screen-to-body ratio of the display module. A first support and protection part is provided on the side of the panel bending portion away from the multiple functional film layers. The first support and protection part can be directly assembled onto the support platform of the middle frame, ensuring that there is a first support and protection part between the panel bending portion and the middle frame. This prevents the panel bending portion from directly colliding with the middle frame, thus eliminating the need for a large space between the panel bending portion and the middle frame. This effectively reduces the distance between the panel bending portion and the middle frame, resulting in a smaller bezel width on the side of the display module with the panel bending portion, further increasing the screen-to-body ratio of the display module.

[0212] This application also provides a display device, which may include: a frame and a display module connected to the frame. The display module may be the display module shown in Figures 1, 2, and 5 to 16.
