[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] Compared with traditional screens, flexible screens have the characteristics of light volume, low power consumption, and bendability, and are widely used in foldable electronic devices. In foldable electronic devices, a hinge is usually used to achieve the folding and unfolding of multiple flexible screens. In the process of realizing the present invention, the inventors found that there are the following problems in the related technology: Compared with traditional screens, flexible screens have the characteristics of light volume, low power consumption, and bendability, and are widely used in foldable electronic devices. In foldable electronic devices, a hinge is usually used to achieve the folding and unfolding of multiple flexible screens. For example, in a three-fold product, the rebound force of the screen on the outer folding side is large and the impact resistance is poor; in addition, both bending zones need to move through the hinge, and affected by the thickness of the hinge, the thickness of the whole machine is usually large.

[0049] In view of the above technical problems, an embodiment of the present application provides a display module, which includes a support plate, including a supporting main body and a supporting extension connected to each other; a cover plate, including a cover plate main body and a cover plate extension connected to each other; a display film layer, located between the supporting main body and the cover plate main body, and having a receiving space between the supporting extension and the cover plate extension; and a colloid, which is arranged between the supporting extension and the cover plate extension and fills at least part of the receiving space. In an embodiment of the present application, by arranging the supporting extension and the cover plate extension, the attachment area of ​​the display module after bending can be increased, and cracking caused by excessive rebound force can be avoided or reduced. In addition, by arranging the colloid between the supporting extension and the cover plate extension, not only can the bonding area of ​​the display module be increased to avoid debonding, but also the impact resistance of the display module can be improved.

[0050] Figure 1 It is a structural schematic diagram of a display module provided in one embodiment of the present application. Figure 2 is a schematic diagram of a cross-sectional structure of a display module provided by an embodiment of the present application. Specifically, Figure 2 yes Figure 1 The cross-sectional structure diagram of the display module along the A1A2 direction is shown in FIG. Figure 1 and Figure 2As shown, the display module includes a support plate 10, a cover plate 20, a display film layer 30 and a colloid 40. The support plate 10 includes a support body 110 and a support extension 120 connected to each other, and the cover plate 20 includes a cover body 210 and a cover extension 220 connected to each other. The display film layer 30 is located between the support body 110 and the cover body 210. That is, the area of ​​the support body 110 is equal to the area of ​​the display film layer 30, and the area of ​​the cover body 210 is equal to the area of ​​the display film layer 30. In an embodiment of the present application, there is a receiving space between the support extension 120 and the cover extension 220, and the colloid 40 is arranged between the support extension 120 and the cover extension 220 and fills at least part of the receiving space. The colloid 40 can not only provide bonding between the support extension 120 and the cover extension 220, but also improve the impact resistance of the display module (e.g., the cover).

[0051] In the embodiment of the present application, the material of the colloid 40 includes at least one of foam adhesive (Foam Adhesive), optically clear adhesive (Optically Clear Adhesive, OCA), and pressure sensitive adhesive (Pressure Sensitive Adhesive, PSA). Preferably, the material of the colloid 40 includes foam adhesive. The support plate 10 is used to provide support for the display module, and the support plate 10 needs to be bendable. Optionally, the material of the support plate 10 includes at least one of metal and carbon fiber. The material of the cover plate 20 includes at least one of transparent polyimide (Colorless Polyimide, CPI) and ultra-thin flexible glass (Ultra Thin Glass, UTG).

[0052] like Figure 1 As shown, the display film layer 30 includes a notch 301, and the support extension portion 120 and the cover plate extension portion 220 correspond to part of the notch 301. In the embodiment of the present application, the "notch" is formed by removing a portion of the rectangular display film layer. After the display module is bent, the position of the "notch" at least corresponds to the position of the photosensitive device. Specifically, the photosensitive device may include a camera. It can be understood that the shape of the notch 301 can be set according to actual needs. Exemplarily, the shape of the notch 301 includes at least one of a rectangle, an ellipse, a circle, and a trapezoid. Specifically, the display film layer 30 includes a first display portion 310 and a second display portion 320. The first display portion 310 and the second display portion 320 are arranged along a first direction (i.e. Figure 1 The notch 301 may be located on one side of the first display portion 310 in the first direction and on one side of the second display portion 320 in the second direction (i.e., Figure 1 On one side in the x direction), the second direction is perpendicular to the first direction.

[0053] Optionally, in the first direction, the length of the second display portion 320 is greater than the length of the support extension portion 120, and / or the length of the second display portion 320 is greater than the length of the cover extension portion 220. In this way, after the display module is bent, the support extension portion 120 and / or the cover extension portion 220 can avoid the photosensitive device. Optionally, in the first direction, the length of the second display portion 320 is 5 to 60 mm. Exemplarily, the length of the second display portion 320 is 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm or 60 mm. In the first direction, the length of the support extension portion 120 is 5 to 15 mm. Exemplarily, the length of the support extension portion 120 is 5 mm, 7 mm, 10 mm, 12 mm, 14 mm or 15 mm. In the first direction, the length of the cover extension portion 220 is 5 to 15 mm. Exemplarily, the length of the cover extension 220 is 5 mm, 7 mm, 10 mm, 12 mm, 14 mm or 15 mm. In the embodiment of the present application, the length of the support extension 120 is the same as the length of the cover extension 220. It can be understood that the lengths of the second display portion 320, the support extension 120, and the cover extension 220 are only examples, and appropriate sizes can be selected according to actual conditions, as long as the support extension 120 and the cover extension 220 can avoid the photosensitive device after the display module is bent.

[0054] In the embodiments of the present application, Figure 2 As shown, in the first direction, the length of the colloid 40 is less than or equal to the length of either the support extension 120 or the cover extension 220. In the first direction, the length of the colloid 40 is 5 to 15 mm. Exemplarily, the length of the colloid 40 is 5 mm, 7 mm, 10 mm, 12 mm, 14 mm or 15 mm. Optionally, the length of the colloid 40 is equal to the length of the support extension 120 or the cover extension 220. At this time, the side wall of the colloid 40 is in contact with the side wall of the display film layer 30, which can improve the sealing performance of the display film layer 30 and avoid water vapor intrusion. It can be understood that during the preparation process, considering the process error, the side wall of the colloid 40 and the side wall of the display film layer 30 may have a gap (for example, a gap of several angstroms).

[0055] like Figure 1 As shown, the second display portion 320 has a rectangular shape, and the support extension portion 120 and / or the cover extension portion 220 has a rectangular shape. At this time, after the display module is bent, it has the largest external display area and attachment area.

[0056] Figure 3 is a schematic diagram of a cross-sectional structure of a display module provided by another embodiment of the present application. Specifically, Figure 3 yes Figure 1The cross-sectional structure diagram of the display module shown is along line A1A2. Figure 3 The display module shown is Figure 2 The difference between the display module shown is that the display module also includes a support layer 50 and a polarizing layer 60. Part of the support layer 50 is located between the support plate 10 and the display film layer 30, and part of the support layer 50 is located between the support plate 10 and the colloid 40, or the orthographic projection of the support layer 50 on the plane where the support plate 10 is located overlaps with the display film layer 30 on the support plate 10. Since the support layer 50 also has a certain rigidity, it will increase the rebound force when the display module is bent. In addition, the support layer 50 mainly provides support for the display film layer 30, and the area of ​​the support layer 50 can be set to be the same as the area of ​​the display film layer 30, such as Figure 4 shown. Figure 4 is a schematic diagram of a cross-sectional structure of a display module provided by another embodiment of the present application. Specifically, Figure 4 yes Figure 1 The cross-sectional structure diagram of the display module shown is along line A1A2. Figure 4 The display module shown is Figure 3 The difference between the display modules shown is that the support layer 50 is located between the support plate 10 and the display film layer 30, and the orthographic projection of the support layer 50 on the plane where the support plate 10 is located overlaps with the orthographic projection of the display film layer 30 on the plane where the support plate 10 is located. In this way, the rebound force when the display module is bent will not be increased, and support can be provided for the display film layer 30.

[0057] like Figure 3 and Figure 4 As shown, the display module further includes a polarizing layer 60. The polarizing layer 60 is located between the display film layer 30 and the cover plate 20, and the orthographic projection of the polarizing layer 60 on the plane where the support plate 10 is located overlaps with the orthographic projection of the display film layer 30 on the plane where the support plate 10 is located. Optionally, the display module further includes a transparent adhesive layer, located between the polarizing layer 60 and the cover plate 20. The transparent adhesive layer is used for bonding between the polarizing layer 60 and the cover plate 20.

[0058] In the above embodiment, in the first direction, the length of the support extension 120 and the cover extension 220 is less than the length of the second display portion 320, so as to avoid the photosensitive device when the display module is bent. Optionally, in the first direction, the length of the support extension 120 and / or the cover extension 220 is equal to the length of the second display portion 320, and a hole is dug at the position corresponding to the photosensitive device to avoid the photosensitive device. Figures 5 to 7 shown.

[0059] Figure 5 It is a structural schematic diagram of a display module provided in yet another embodiment of the present application. Figure 6 is a schematic diagram of a cross-sectional structure of a display module provided by another embodiment of the present application. Specifically, Figure 6 yes Figure 5 The cross-sectional structure diagram of the display module along the B1B2 line is shown in FIG. Figure 5 and Figure 6 As shown, the display film layer 30 includes a notch 301, and the support extension portion 120 and the cover extension portion 220 correspond to the notch 301. In the first direction (i.e., the y direction), the length of the second display portion 320 is equal to the length of the support extension portion 120, and / or, the length of the second display portion 320 is equal to the length of the cover extension portion 220.
