[0043] 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.

[0044] like Figure 1 As shown, the embodiment of the present application provides a display module, including a rear shell 1 and a middle frame 2, and a display screen 3, an ultra-thin protective cover plate 4, and a protective film 5 which are located on a side of the middle frame 2 away from the rear shell 1 and are stacked in sequence; wherein:

[0045] The rear housing 1 comprises a back plate 11 and a first folded edge 12 extending from the edge of the back plate 11 toward one side of the display screen 3; the middle frame 2 is located in the area surrounded by the back plate 11 and the first folded edge 12;

[0046] The ultra-thin protective cover plate 4 has a first surface facing away from the display screen 3 and a side surface located at the edge;

[0047] The protective film 5 includes a first portion 51 that is attached to the first surface of the ultra-thin protective cover plate 4 , and a second portion 52 that covers the side surface of the ultra-thin protective cover plate 4 and extends between the middle frame 2 and the first folded edge 12 of the rear shell 1 .

[0048] In the above display module, the protective film 5 is covered on the ultra-thin protective cover plate 4 and includes two parts (a first part 51 and a second part 52). Specifically, in addition to the first part 51 attached to the first surface of the ultra-thin protective cover plate 4, it also includes a second part 52 bent from the edge of the first part 51 and extending into the rear shell 1. Then, the ultra-thin protective cover plate 4 is entirely covered inside the protective film 5, and the edge part (the second part 52) ​​of the protective film 5 is assembled and limited between the middle frame 2 and the first folded edge 12 of the rear shell 1, so that when the ultra-thin protective cover plate 4 is bent and attached at the edge (such as Figure 1 When the curved screen is attached as shown in FIG. 1 ) or when the curved screen is bent, no film separation will occur between the display screen 3 due to the rebound force.

[0049] In summary, the display module provided in the embodiment of the present application can improve the situation where the ultra-thin protective cover plate is separated from the film layer due to excessive rebound force when attached to a curved screen or bent, thereby improving the yield of the display product.

[0050] In some embodiments, the ultra-thin protective cover plate 4 is ultra-thin glass (UTG).

[0051] Furthermore, the protective film 5 is a transparent polymer plastic film, which may include a transparent polyimide film (CPI) or a polyethylene terephthalate plastic film (PET). For example, the protective film 5 may include a transparent polyimide film and a hardening coating located on the side of the transparent polyimide film away from the ultra-thin protective cover plate 4, and the hardening coating may be an acrylic material.

[0052] Ultra-thin glass (UTG) refers to a glass layer with a thickness of tens of microns or less, which can be bent, deformed, and folded. Specifically, as early as four years ago, Schott Glass Manufacturer had already produced 70-micron deformable ultra-thin glass. At present, some mobile phone manufacturers have already used Schott's 30-micron thick deformable glass, and Schott also stated that the thickness of the glass can be reduced to 25 microns in the laboratory. Specifically, compared with polymer plastic film, ultra-thin glass can effectively avoid screen damage and provide better optical clarity; at the same time, ultra-thin glass is not prone to creases and has good reliability; and it will not be naturally decomposed like plastic, and has a long life, thereby providing more stable and reliable protection for the display.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the ultra-thin protective cover plate 4 is square, and at least one edge of the ultra-thin protective cover plate 4 is bent toward one side of the rear shell 1 .

[0054] Exemplarily, the bending angle of the edge of the ultra-thin protective cover plate 4 toward the side of the rear shell 1 is less than or equal to 90 degrees.

[0055] Specifically, the display module of the embodiment of the present application may be a curved display module, wherein the ultra-thin protective cover plate 4 is a curved cover plate, and the display screen 3 is a curved screen having a curved shape substantially the same as that of the ultra-thin protective cover plate 4 .

[0056] Exemplarily, the second portion 52 of the protective film 5 covers the edge side of the at least one side edge of the ultra-thin protective cover plate 4 and extends to between the middle frame 2 and the first folded edge 12 of the rear shell 1. In other words, the protective layer extends to form the second portion 52 on the side where the edge of the ultra-thin protective cover plate 4 is bent, so as to cover and restrict the side edge of the ultra-thin protective cover plate 4, thereby preventing the film layer from being separated from the display screen 3 under the action of the rebound force.

[0057] In a specific embodiment, taking the display module of a curved screen mobile phone as an example, Figure 1 and Figure 2 As shown, the display screen 3 is rectangular and is a curved screen with curved long sides on both sides; the ultra-thin protective cover plate 4 is attached to the display screen 3, and the curved shapes of the edges of the two are roughly the same, that is, the ultra-thin protective cover plate 4 is also rectangular, and the two opposite long sides are also curved toward the side of the rear shell 1. Specifically, the bending angle of the edge of the display screen 3 and the ultra-thin protective cover plate 4 is roughly 90 degrees, and the edge of the ultra-thin protective cover plate 4 can be aligned with the edge of the display screen 3, or exceed the edge of the display screen 3.

[0058] For example, Figures 1 to 3 As shown, the first portion 51 of the protective film 5 is attached to the first surface 41 of the ultra-thin protective cover plate 4, and is substantially the same shape as the first surface 41 of the ultra-thin protective cover plate 4, which is a rectangular shape. The second portion 52 of the protective film 5 includes two parts, which are respectively located on both sides of the first portion 51 close to the two long edges, and respectively cover the edge side surfaces 42 of the two long sides of the ultra-thin protective cover plate 4 and extend to between the middle frame 2 and the first folded edge 12 of the rear shell 1.

[0059] Specifically, when the curved display module of the embodiment of the present application is applied to a mobile phone, the overall curved design of the curved screen of the mobile phone can be made easier to hold, and fit better with the curvature of the palm, reducing the distance that the thumb touches the screen when operating with one hand, which theoretically helps to improve the experience of horizontal cross-screen operation under a large-size screen. It can also make the screen thinner, lighter and less power-consuming. In addition, the curved screen increases the viewing angle, so even if you watch at an angle off-center, the effect is good.

[0060] In a specific embodiment, Figure 4As shown, the display screen is a flexible display screen, which may include a square screen portion 31, and a bent portion 32 located at a first side edge of the screen portion 31 and bent to a non-display side of the screen portion. Specifically, at this time, the ultra-thin protective cover plate 4 matches and fits the shape of the screen portion 31, and an edge of one side of the ultra-thin protective cover plate 4 close to the first side edge of the screen portion 31 is bent toward the side of the rear shell 1.

[0061] Exemplarily, at this time, the second portion 52 of the protective film 5 covers the edge side of the ultra-thin protective cover plate 4 close to the first side edge and extends to between the middle frame 2 and the first folded edge 12 of the rear shell 1 .

[0062] In other words, when the display screen includes a bent portion 32 bent toward the back, the side of the ultra-thin protective cover plate 4 close to the bent portion 32 can be bent toward the side of the rear housing 1 to protect the curved screen on that side. Accordingly, the protective film 5 can also extend on that side to form a second portion 52 to prevent the bent edge of the ultra-thin protective cover plate 4 from being separated from the display screen under the action of the rebound force.

[0063] For example, taking a curved mobile phone as an example, the screen portion 31 of the display screen is rectangular, and the first side of the screen portion 31 is a short side of the screen portion 31. Specifically, the long sides of both sides of the screen portion 31 are bent toward one side of the rear shell 1 (such as Figure 1 The bent portion 32 is bent along the first side of the screen portion 31 to the back side of the screen portion 31 (as shown in Figure 4 The ultra-thin protective cover plate 4 matches and fits the screen portion 31 in shape, that is, the two long edges of the ultra-thin protective cover plate 4 are bent toward one side of the rear housing 1 (as shown in Figure 1 ), and one side edge close to the first side edge of the screen portion 31 is also bent toward the rear housing 1 (as shown in Figure 4 ), thereby protecting the curved edges of the screen portion 31. Accordingly, the second portion 52 of the protective film 5 simultaneously covers the edge sides of the three sides of the ultra-thin protective cover plate 4 and extends between the middle frame 2 and the first folded edge 12 of the rear shell 1.

[0064] In some embodiments, such as Figure 1 As shown, the second portion 52 of the protective film 5 is adhered and fixed to the first folded edge 12 of the rear shell 1. That is, the edge portion of the protective film 5 is adhered to the first folded edge 12 of the rear shell 1 to ensure that the edge of the protective film 5 is stably limited in the rear shell 1.

[0065] Exemplarily, a double-sided tape (not shown in the figure) is provided between the second portion 52 of the protective film 5 and the first folded edge 12 of the rear shell 1, and the second portion 52 of the protective film 5 and the first folded edge 12 of the rear shell 1 are adhered together by the double-sided tape.

[0066] In some embodiments, Figure 5 and Figure 6 As shown, the second portion 52 of the protective film 5 is provided with an opening 520 at a position between the middle frame 2 and the first folded edge 12 of the rear shell 1. Specifically, a protrusion 120 matching the opening 520 is provided on the inner side of the first folded edge 12 of the rear shell 1, and the protrusion 120 is inserted into the opening 520.

[0067] Specifically, by inserting and fitting the protrusion 120 of the first folded edge 12 into the opening 520 of the second portion 52 , a snap connection between the edge of the protective film 5 and the rear shell 1 can be achieved, thereby further ensuring the stability of the edge of the protective film 5 being limited in the rear shell 1 .

[0068] For example, Figure 3 As shown, taking the second part 52 of the protective film 5 mentioned in the above specific embodiment as comprising two parts, at this time, each of the two parts is provided with a plurality of the openings 520, and the plurality of openings 520 are arranged and distributed along the long edge of the ultra-thin protective cover plate (the long edge of the first part 51). Further, at this time, the inner side of the first folded edge 12 of the rear shell 1 may be provided with a plurality of protrusions 120 corresponding to the plurality of the openings 520, and each of the protrusions 120 is inserted into the corresponding opening 520.

[0069] In some embodiments, Figure 7 As shown, the display module provided in the embodiment of the present application may further include a clamp 7, which is arranged in the area surrounded by the back plate 11 and the first folded edge 12 of the rear shell 1, and is configured to clamp and fix the middle frame 2 and the second part 52 of the protective film 5, thereby allowing the edge of the protective film 5 (the second part 52) ​​to be better limited in the rear shell 1.

[0070] For example, Figure 1 As shown, the middle frame 2 includes a main body 21 opposite to the back plate 11 of the rear shell 1 and used to carry the display screen 3 and the ultra-thin protective cover plate 4, and a second folded edge 22 bent from the edge of the main body toward the back plate 11 of the rear shell 1. The second portion 52 of the protective film 5 extends between the second folded edge 22 of the middle frame 2 and the first folded edge 12 of the rear shell 1.

[0071] Furthermore, if Figure 1 , Figure 7 and Figure 8As shown, the clamp 7 can be a fully enclosed or semi-enclosed frame body arranged along the second folded edge 22 of the middle frame 2, and is provided with a clamping groove 71 opened on the side of the back plate 11 away from the rear shell 1, and the clamping groove 71 clamps the second part 52 of the protective film 5 and the second folded edge 22 of the middle frame 2. Specifically, the clamping groove 71 can be a strip groove or an annular groove extending along the second folded edge 22 of the middle frame 2. For example, the second part 52 of the protective film 5 mentioned in the above specific embodiment includes two parts (such as Figure 3 As shown), at this time, Figure 8 As shown, the clamping groove 71 may include two strip-shaped grooves extending along two long sides of the middle frame 2 .

[0072] In some embodiments, the clamp 7 may be an elastic body; the opening size of the clamp groove 71 in the clamp 7 is smaller than the size inside the clamp groove 71. Specifically, the size inside the clamp groove 71 refers to the radial size of the cross section. In other words, when the clamp groove 71 is a strip or annular shape, the width inside the clamp groove 71 is greater than the width of the opening, which facilitates clamping the second folded edge of the middle frame and the second part of the protective film, and can improve the tightness of the clamping. For example, the longitudinal section of the clamp groove 71 may be trapezoidal.

[0073] In some embodiments, the clamp 7 can be adhered and fixed to the rear housing 1 .

[0074] In some embodiments, in the display module provided in the embodiments of the present application, the display screen may be an OLED panel.

[0075] In some embodiments, Fig. 9 As shown, the display module provided in the embodiment of the present application may further include a plastic diaphragm 8 located between the display screen 3 and the ultra-thin protective cover plate 4. The plastic diaphragm 8 may be a transparent polymer plastic film, such as a transparent polyimide film (CPI) or a polyethylene terephthalate plastic film (PET). Specifically, the plastic diaphragm 8 may match the shape of the ultra-thin protective cover plate 4, and the two side surfaces may be bonded to the ultra-thin protective cover plate 4 and the display screen 3, respectively, and may be bonded by transparent optical adhesive (OCA).

[0076] Specifically, the display module provided in the embodiment of the present application may further include a transparent optical adhesive (OCA) 6 (such as Figures 5 to 7 ), and a heat dissipation module (not shown in the figure) and a stainless steel support layer 8 (as shown in the figure) located between the middle frame 2 and the display screen 3 Figure 4 In addition, a main circuit board and other functional modules (not shown in the figure) may be included between the middle frame 2 and the rear shell 1, which will not be described in detail here.

[0077] In addition, the present application also provides a display device, which includes any one of the display modules described above.

[0078] Specifically, the display device may be an OLED display device, which may be applied to display devices such as tablet computers and mobile phones.

[0079] It should be noted that in some embodiments of the present disclosure, the display module and the display device may also include other structures, which may be determined according to actual needs, and the embodiments of the present disclosure are not limited to this. In addition, the size and material selection of each structure provided in the embodiments of the present disclosure are not limited to the above embodiments, and their basic requirements can be referred to the description above, which will not be repeated here. Furthermore, the drawings of the present application are only schematic diagrams, and the size and proportion of each part of the structure in the figure do not represent the actual size proportion of each structure.

[0080] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
