[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. And the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict if possible. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present disclosure.

[0029] Unless otherwise defined, technical terms or scientific terms used in the present disclosure shall have the ordinary meaning of the terms to a person of ordinary skill in the art to which the present disclosure belongs. The terms “first”, “second” and similar terms used in the present disclosure do not denote any order, quantity or importance, but are used to distinguish different components. The terms “include” or “contain” and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms “connect” or “connected” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “inner”, “outer”, “upper”, “lower” and the like only represent relative positional relationships, which can change accordingly when the absolute positions of the described objects change.

[0030] It should be noted that the sizes and shapes of the figures in the drawings do not reflect the true proportions, but only serve to illustrate the present disclosure. And the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout the drawings.

[0031] The requirement of screen ratio in display panel industry is getting higher and higher. Full screen display products (such as mobile phones) rapidly fill the market. The current novel full screen mobile phone is to dig a hole in the middle of the display module and place a photosensitive component such as a camera. At the same time, in order to ensure the portability of the display product, foldable display screen has also become a trend. However, when both the hole digging in the middle of the display module and the foldable display screen are taken into account, the flexible cover film needs to be used instead of the rigid cover glass in the folding module. In one embodiment, as shown in Figure 1 , the hole digging area 01 usually only retains the flexible cover film 02, and the remaining film layers and structures in the display panel 03 need to be cut off, so that the camera 04 can be arranged in the hole digging area 01. However, the current product is prone to the problem of concave flexible cover film 02 in the hole digging area 01, which causes the change of light refraction angle at the concave position, thereby affecting the imaging quality of the camera 04, that is, affecting the picture shooting performance of the display product (such as mobile phone).

[0032] Therefore, the display module provided by the embodiments of the present disclosure, as shown in Figure 2 and Figure 3 , Figure 2 is a top view structural schematic diagram of the display module, Figure 3 is Figure 2 a cross-sectional schematic diagram along the direction of CC' in the display module. The display module can include:

[0033] a display panel 1 having a display area AA and a light transmission area BB, the light transmission area BB having a light transmission hole V1; the present disclosure Figure 1 The display area AA is arranged around the light transmission area BB. Of course, the light transmission area BB can also be arranged at the boundary of the display area AA, and the present disclosure does not make specific limitation on the position of the light transmission area BB;

[0034] a flexible cover film 2 located on the light emitting side of the display panel 1 and covering the display area AA and the light transmission area BB;

[0035] a transparent support structure 3 located on the side of the display panel 1 facing the flexible cover film 2, the transparent support structure 3 covering the light transmission hole V1, and the orthogonal projection of the transparent support structure 3 on the flexible cover film 2 and the orthogonal projection of the display panel 1 on the flexible cover film 2 having an overlapping area.

[0036] The transparent support structure in the display module provided by the embodiments of the present disclosure is located on the side of the display panel facing the flexible cover plate, and covers the light transmission hole. Therefore, the present disclosure sets the transparent support structure between the light transmission hole of the display panel and the flexible cover plate, and the transparent support structure can compensate the strength of the light transmission hole. In addition, the orthogonal projection of the transparent support structure on the flexible cover plate and the orthogonal projection of the display panel on the flexible cover plate have an overlapping area, that is, the periphery of the transparent support structure is supported by the display panel. Therefore, the transparent support structure can better support the flexible cover plate at the light transmission hole, and prevent the flexible cover plate from being concave. Therefore, the display module provided by the embodiments of the present disclosure can prevent the problem that the concave of the flexible cover plate at the light transmission hole (i.e. the camera hole) affects the camera shooting performance due to the cutting of other non-transparent film layers.

[0037] In specific implementation, the display panel can be a flexible display panel, and the display panel can include a driving layer, a light-emitting layer and an encapsulation layer which are stacked, wherein the driving layer can include a plurality of metal film layers and a plurality of inorganic insulating film layers, the light-emitting layer can include an anode, an organic light-emitting layer and a cathode, and the encapsulation layer can be a thin film encapsulation layer. The light transmission hole can be a through hole, that is, the light transmission hole penetrates all the film layers of the display panel; or can be a blind hole including a transparent layer, that is, the light transmission hole penetrates part of the non-transparent film layers of the display panel. The transparent layer can be silicon oxide, silicon nitride or other transparent insulating layer, and the present disclosure does not make specific limitation on the material of the transparent layer.

[0038] In specific implementation, in the display module provided by the embodiments of the present disclosure, the material of the transparent support structure can be transparent glass. The transparent glass is used as the material of the transparent support structure and is arranged above the light transmission hole of the display panel, which can support the flexible cover plate and will not affect the light transmission of the light transmission hole. Of course, it should be understood that the material of the transparent support structure can be selected according to specific application requirements, as long as it is a transparent material that does not affect the light transmission of the light transmission hole and the transparent support structure produced can play a supporting role, which belongs to the protection range of the present disclosure, and the present disclosure does not make specific limitation on the material of the transparent support structure.

[0039] In specific implementation, in the display module provided by the embodiments of the present disclosure, in order to prevent the problem that the ambient light is reflected back to the display panel and affects the viewing effect and contrast, the display module can further include a light shielding layer arranged on the display panel and covering the light transmission hole. Figure 3As shown, the display module further includes a polarizer 4 located on the side of the display panel 1 facing the flexible cover plate 2. The polarizer 4 and the transparent support structure 3 can be arranged on the same layer. The polarizer 4 and the transparent support structure 3 on the same layer can support the flexible cover plate 2 by the transparent support structure 3 without increasing the thickness of the display module. Since the transparent support structure 3 is arranged on the flexible cover plate 2 and then attached to the display panel 1 provided with the polarizer 4, the polarizer 4 is arranged around the transparent support structure 3 with a gap between the polarizer 4 and the transparent support structure 3, which facilitates the attachment of the transparent support structure 3.

[0040] It should be noted that the polarizer 4 and the transparent support structure 3 on the same layer do not mean that the polarizer 4 and the transparent support structure 3 are formed by one patterning process. Instead, the polarizer attached to the display panel 1 has a through hole, and the transparent support structure 3 is attached to the through hole of the polarizer 4, so that the transparent support structure 3 and the polarizer 4 are on the same layer, and the transparent support structure 3 can support the flexible cover plate 2 without increasing the thickness of the module.

[0041] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figure 4 and Figure 5 The display module can also be a display module with touch function. The display module further includes a touch layer 5 located between the display panel 1 and the polarizer 4. The touch layer 5 has no metal traces at the corresponding positions of the light transmission holes V1. Figure 4 When the display module includes a touch layer 5 between the display panel 1 and the polarizer 4, as shown in Figure 6 , the touch layer 5 and the display panel 1 can be used to support the transparent support structure 3 at the same time; or only the display panel 1 can be used to support the transparent support structure 3, as shown in

[0042] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figures 3-5 The display module further includes an optical adhesive layer 6 located between the polarizer 4 and the flexible cover plate 2. The orthogonal projection of the optical adhesive layer 6 on the flexible cover plate 2 covers the orthogonal projection of the display area AA and the light transmission area BB on the flexible cover plate 2, i.e. the optical adhesive layer 6 is a whole structure, so that the transparent support structure 3 can be bonded with the optical adhesive layer 6. Specifically, the optical adhesive (Optically Clear Adhesive, OCA) has high bonding strength and high transparency, and does not affect the display effect of the display panel.

[0043] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figure 3 and Figure 4As shown, since the transparent support structure 3 is bonded to the position corresponding to the light transmission hole V1 of the flexible cover plate 2 through the optical adhesive layer 6, and the position of the optical adhesive layer 6 except for the position of bonding the transparent support structure 3 needs to be bonded with the polarizer 4, in order to ensure that the optical adhesive layer 6 is firmly bonded around the polarizer 4, the thickness of the polarizer 4 and the thickness of the transparent support structure 3 are the same in the thickness direction of the display panel 1, so that the optical adhesive layer 6 can be bonded together with the polarizer 4 and the transparent support structure 3 flush, and the flatness of the film layer is better.

[0044] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figure 5 As shown, when the display module includes the touch layer 5, and only the display panel 1 is used to support the transparent support structure 3. In the thickness direction of the display panel 1, the thickness of the transparent support structure 3 can be the same as the sum of the thicknesses of the polarizer 4 and the touch layer 5, so that the optical adhesive layer 6 can be bonded together with the polarizer 4 and the transparent support structure 3 flush, and the flatness of the film layer is better.

[0045] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figures 3-5 As shown, in order to solve the light leakage problem, an optical shielding layer 10 is further included on the side of the flexible cover plate 2 facing the display panel 1, the orthogonal projection of the optical shielding layer 10 on the flexible cover plate 2 covers part of the light transmission hole V1 and the orthogonal projection of the part of the display area AA adjacent to the light transmission hole V1 on the flexible cover plate 2; the optical shielding layer 10 has a first through hole H1 at the position corresponding to the light transmission hole V1, and the diameter of the first through hole H1 is smaller than the diameter of the light transmission hole V1.

[0046] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figures 3-5 As shown, the center axis of the first through hole H1 and the center axis of the light transmission hole V1 coincide, which can achieve the effect of uniformly shielding the light transmission hole V1 by the optical shielding layer 10.

[0047] In specific implementation, in the above display module provided by the embodiments of the present disclosure, the material of the optical shielding layer can be ink.

[0048] In specific implementation, in the above display module provided by the embodiments of the present disclosure, as shown in Figures 3-5 As shown, a back film 7 is further included on the side of the display panel 1 away from the flexible cover plate 2, and the back film 7 has a second through hole H2 corresponding to the light transmission hole V1.

Specifically, the material of the support layer can be stainless steel.

[0050] It should be noted that, Figures 3-5 only one structure in the display module is shown in the embodiment of the present disclosure, and other structures can also be included in actual applications, and the present disclosure does not make specific limitations on this.

[0051] In specific implementation, as Figure 3 shown, the shape of the light transmission hole V1 in the embodiment of the present disclosure is rectangular, but is not limited thereto, and the shape of the light transmission hole can also be circular, oval, U-shaped or other irregular shapes, etc.

[0052] The following will take Figure 3 as an example to explain the lamination manufacturing process of the display module shown in Figure 3 .

[0053] (1) The display panel 1 is manufactured on the back film 7, and the back film 7 and the display panel 1 are subjected to shape cutting to form a required shape, for example, a rectangular shape;

[0054] (2) The display panel 1 is opened in the display area to form a light transmission area BB and a display area AA surrounding the light transmission area BB;

[0055] (3) The polarizing plate 4 is laminated on the light-emitting side of the display panel 1, and a certain position on the light-emitting side of the display panel 1 is left as a subsequent transparent support structure 3;

[0056] (4) The flexible cover plate 2 is provided, and the light shielding layer 10 is bonded on one side of the flexible cover plate 2 through the optical adhesive layer 6;

[0057] (5) The transparent support structure 3 is bonded on the other side of the optical adhesive layer 6, and the position of the transparent support structure 3 corresponds to the position of the light transmission hole V1;

[0058] (6) The flexible cover plate 2 of step (5) and the display panel 1 of step (3) are aligned and laminated, so that the transparent support structure 3 is attached above the light transmission hole V1 of the display panel 1, and is located in the same layer as the polarizing plate 4, and the transparent support structure 3 and the polarizing plate 4 have a preset distance therebetween;

[0059] (7) The support layer 8 is bonded on the side of the back film 7 away from the display panel 1.

[0060] The display module shown in Figure 3 can be obtained through the installation sequence of the above steps (1)-(7).

[0061] In specific implementation, the bonding process is carried out through the above steps (1)-(7). Figure 3 In the display module shown, there are bonding tolerances in each step. The bonding tolerance between the polarizer 4 and the display panel 1 is about 0.1 mm, the opening shape tolerance of the polarizer 4 is about 0.1 mm, and the bonding tolerance between the flexible cover plate 2 and the polarizer 4 is about 0.15 mm. Along the extension direction of the flexible cover plate 2, the gap width D1 between the polarizer 4 and the transparent support structure 3 is greater than or equal to 0.45 mm.

[0062] In specific implementation, such as Figure 3 As shown, the bonding tolerance between the light-shielding layer 10 and the flexible cover plate 2 via the optical adhesive layer 6 is approximately 0.1 mm, the dimensional tolerance of the transparent support structure 3 is approximately 0.1 mm, and the bonding tolerance of the transparent support structure 3 is approximately 0.2 mm. In the embodiments of this disclosure, the width D2 of the overlapping portion of the orthographic projection of the light-shielding layer 10 and the transparent support structure 3 on the flexible cover plate 2 is greater than or equal to 0.4 mm. Furthermore, considering the blocking effect of the light-shielding layer 10 on the display panel 1, the width value of D2 can also be greater than 0.44 mm.

[0063] In specific implementation, in the display module provided in the embodiments of this disclosure, such as Figures 6-8 As shown, the opening tolerance of the light-transmitting hole V1 is about 0.1 mm, and the bonding tolerance of the flexible cover plate 2 and the polarizer 4 is about 0.15 mm; along the extension direction of the flexible cover plate 2, the distance D3 between the inner wall of the light-transmitting hole V1 and the side a of the transparent support structure 3 is greater than or equal to 0.44 mm.

[0064] Based on the same disclosed concept, this disclosure also provides a display device, including the display module described above in this disclosure.

[0065] In specific implementation, in the display module provided in the embodiments of this disclosure, such as Figures 6-8 As shown, it also includes a camera 9, which is at least partially located within a light-transmitting hole V1. Specifically, the light-transmitting hole V1 is used to transmit the light required by the camera 9; therefore, this disclosure ensures the light transmittance requirements of the camera 9 integrated under the display panel. Furthermore, by punching a hole in the display module to house at least a portion of the camera 9, the space occupied by the camera 9 in the display area of ​​the display module is reduced, thereby increasing the screen-to-body ratio of the display device.

[0066] Specifically, such as ​As shown, since the light transmission hole V1 can be a through hole penetrating the display panel 1, or a blind hole, that is, a transparent layer is reserved and the opaque layer is etched off; when the light transmission hole V1 is a through hole, the camera 9 can be deep into the light transmission hole V1; when the light transmission hole V1 is a blind hole, part of the camera 9 is located in the light transmission hole V1, so the camera 9 is placed in the area corresponding to the light transmission hole V1 of the display panel 1, and whether the camera 9 is deep into the light transmission hole V1 and how deep it is depends on the actual situation.

[0067] The display device solves the problem by the similar principle as the display module, so the implementation of the display device can refer to the implementation of the display module, and the repeated parts will not be described here.

[0068] In the specific implementation, in the embodiments of the present disclosure, the display device can be any product or component with display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, etc. Other essential components of the display device should be understood by those skilled in the art, and will not be described here, nor should it be regarded as a limitation on the present disclosure.

[0069] The display module and the display device provided by the embodiments of the present disclosure, the transparent support structure in the display module is located on the side of the display panel facing the flexible cover plate, and the transparent support structure covers the light transmission hole, so the present disclosure sets the transparent support structure between the light transmission hole of the display panel and the flexible cover plate, and the transparent support structure can compensate the strength of the light transmission hole position; and since the orthogonal projection of the transparent support structure on the flexible cover plate and the orthogonal projection of the display panel on the flexible cover plate have an overlapping area, that is, the periphery of the transparent support structure is supported by the display panel, so the transparent support structure can better support the flexible cover plate at the light transmission hole, preventing the flexible cover plate from being concave, so the display module provided by the embodiments of the present disclosure can prevent the problem that the concave of the flexible cover plate at the light transmission hole (i.e. the camera hole) caused by the cutting of other non-light transmission film layers affects the camera shooting performance.

[0070] Although the preferred embodiments of the present disclosure have been described, those skilled in the art can make additional changes and modifications to the embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.

[0071] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalent technologies, the present disclosure also intends to include these modifications and variations.
