Description

[Technical field]

[0001] The present invention relates to the field of display technology, and in particular to a display module and a display device. [Background technology]

[0002] With the continuous development of display technology, in order to achieve a better display effect of the display device, the display module needs to have a larger screen-to-body ratio. Due to the limitation of the physical space occupied by the front camera, the screen of the display module has a part of the area left for installing the camera. Although the design schemes of the display screen such as the bangs screen and the water drop screen can improve the screen-to-body ratio of the display module, they cannot achieve a true full screen, which reduces the overall aesthetics of the display device. In order to further improve the screen-to-body ratio of the display device, the designer introduced an under-screen camera, which can achieve a full screen. However, the use of the under-screen camera leads to a decrease in the shooting quality of the camera and also reduces the strength of the display module. [Summary of the invention]

[0003] In order to solve the above problems, the present invention provides a display module and a display device, which can improve the camera's photographing quality and enhance the mechanical strength of the display module.

[0004] In a first aspect, an embodiment of the present application provides a display module, comprising: a stacked display panel and a support assembly, wherein a side of the display panel facing away from the support assembly is a light emitting side;

[0005] The display panel comprises a bending area, a first plane area and a second plane area located on both sides of the bending area and connected to the bending area;

[0006] The support component comprises an opening, the orthographic projection of the opening in the plane where the display panel is located is located in the first plane area, the opening at least passes through the support component in a direction perpendicular to the plane where the display panel is located, the opening has a first side wall and a second side wall arranged opposite to each other, and the distance between the orthographic projection of the first side wall on the plane where the display panel is located and the bending area is smaller than the distance between the orthographic projection of the second side wall on the plane where the display panel is located and the bending area;

[0007] The display module also includes a camera assembly, which includes a camera body. The camera body is located in the opening, and the distance between the camera body and the first side wall is distributed in a stepped manner along a direction perpendicular to the plane where the display panel is located.

[0008] In a second aspect, an embodiment of the present application further provides a display device, which includes the display module described in the first aspect.

[0009] The technical solution provided by the embodiments of the present application may have the following beneficial effects:

[0010] The present application arranges the distance between the camera body and the first side wall to be distributed in a stepped manner, so that the distance between the camera body and the support assembly can reserve a certain position misalignment for the display module during the bending process, and can compensate for the slippage of the support assembly during the bending and movement process, thereby avoiding interference between the camera body and the support assembly and improving the shooting quality of the camera body. At the same time, this stepped position misalignment can reduce the opening area in the support assembly, thereby ensuring the mechanical properties of the support assembly.

[0069] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0070] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0071] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0072] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0073] As described in the background technology, although the existing display screen design schemes such as the bangs screen and the water drop screen can increase the screen-to-body ratio of the display module, they cannot achieve a true full screen. In order to further increase the screen-to-body ratio of the display device, the designer introduced an under-screen camera, which hides the front camera and all sensors directly under the screen. Therefore, there is no need to reserve a position for the camera on the screen in the form of a bangs screen, nor is there a need for a lifting mechanical structure. However, for a flexible display module, the display module needs to be flattened or folded during use. During the folding process, the film layer in the display module will move to a certain extent, resulting in a misalignment of the film layer. This misalignment will cause interference between the display module and the camera, affecting the camera's photo quality.

[0074] In order to solve the above problems, it is usually necessary to increase the area of ​​the opening where the camera is placed to avoid the influence of the camera on the camera during the bending process of the flexible display module. However, simply increasing the area of ​​the opening will reduce the mechanical properties of the display module.

[0075] Based on the above considerations, in order to solve the problems of mechanical performance of the display module and camera quality, the applicant has conducted in-depth research and provided a display module 10, see Figure 1 and Figure 2 , including: a display panel 1, a support component 2 and a camera component 3, the display panel 1 and the support component 2 are stacked, and the camera component 3 is located inside the support component 2, such as Figure 2 , which is a cross-sectional view of a display module provided in an embodiment of the present application.

[0076] For example, the display panel 1 is an OLED (Organic Light-Emitting Diode), see Figure 3 , the OLED display panel 1 includes an array substrate 11, a light-emitting layer 12 and an encapsulation layer 13 stacked in sequence; wherein the array substrate 11 is mainly used to control the pixel unit in the light-emitting layer 12, and exemplarily, the pixel unit includes at least two sub-pixels of two colors: PX1, PX2 and PX3, so that the OLED display panel 1 presents different colors. The array substrate includes a plurality of pixel circuits arranged in an array, and the pixel circuit includes a thin film transistor (TFT) and a pixel unit connected to the pixel circuit. In the preparation process of the array substrate, the same film layer adopts the same process, and the active layer between different pixel circuits is an integrated graphic structure. The active layer itself is not conductive, and the conductive part of the region is achieved by doping the active layer. The conductive active layer can be electrically connected to the wiring layer to replace part of the wiring. In the specific implementation, optionally, the active layer of each transistor includes a polysilicon active layer or a metal oxide active layer. The polysilicon active layer can be formed by low temperature polysilicon (Low Temperature Poly-Silicon, LTPS) technology, which has the advantages of simple structure, good stability, high electron mobility, and small circuit area. Optionally, the active layer may be made of low temperature polycrystalline oxide (LPTO).

[0077] In other embodiments, the display panel 1 may also be an LCD panel (Liquid Crystal Display). The LCD display panel in the related art includes a stacked backlight source, a lower polarizer, an array substrate, a liquid crystal layer, a color filter, an upper polarizer and a transparent cover. Among them, the backlight source is mainly used to provide a light source for the LCD screen, and the array substrate is mainly used to control the deflection of liquid crystal molecules in the liquid crystal layer so that light beams of different brightness reach the color filter. The color filter is provided with sub-pixels of multiple colors arranged in an array, which are used to make the LCD display panel display different colors. Of course, the display panel can also be other display panels, such as Micro-LED (self-luminous micron-scale LED as the light-emitting pixel unit), MiniLed (LED device with a chip size between 50 and 200μm) and quantum dots, etc., which will not be repeated here.

[0078] It should be noted that the display panel 1 of the present application is a flexible display panel. Figure 1 and Figure 2 , the display panel 1 includes a bending region 14 ( Figure 2 As shown in the dashed box, the first plane area 15 and the second plane area 16 are located on both sides of the bending area 14 and connected to the bending area 14. The bending area 14 has a bending axis ( Figure 2 The first plane area 15 and / or the second plane area 16 rotate around the bending axis to form a bending area 14 in the area where the first plane area 15 and the second plane area 16 are connected. It should be noted that the bending axis is not the actual structure of the display module 10, but is only a concept proposed to illustrate the bending process of the display panel 1. The flexible display module can be switched between a flat state and a bent state. When the flexible display module is in a flat state, the display surface of the flexible display panel is planar, that is, the bending area 14, the first plane area 15 and the second plane area 16 are in the same plane, and the user sees a planar image through the planar flexible display module; when the flexible display module is in a bent state, the display surface of the flexible display panel is curved, that is, the bending area 14, the first plane area 15 and the second plane area 16 are in different planes, and the user sees a curved image through the flexible display module, enriching the user's viewing angle. The embodiment of the present application controls the flexible display module to switch between a flat state and a bent state through a conventional rotating shaft or rotating component in the art.

[0079] In the embodiments of this application, please continue to refer to Figure 2 The support assembly 2 is located on a side of the display panel 1 away from the light emitting side thereof, such as Figure 1 The arrow direction Z in the figure indicates the light emitting direction of the display module 10. For a flexible display panel, its base substrate is a flexible base substrate, so its edge is easy to bend, and its surface is also easy to be scratched. A support component 2 is arranged on the side of the base substrate of the display panel 1 away from the light emitting side. On the one hand, it can prevent the edge of the base substrate from bending and play a supporting role, and on the other hand, it can also prevent the base substrate from being scratched. The support component 2 is a structure originally existing in the display module.

[0080] It should be noted that Figure 1 The display module 10 of the present application is illustrated by taking a rectangle as an example, and the specific shape of the display module is not limited. In some other embodiments of the present invention, the shape of the display module 10 can also be a circle, an ellipse, or other shapes different from a rectangle. In addition, Figure 1 to Figure 3 Only the relative position relationship among the display panel 1 , the support assembly 2 and the camera assembly 3 in the display module 10 is illustrated, and does not represent the actual size of each film layer.

[0081] In the embodiments of this application, please continue to refer to Figure 2The support component 2 includes an opening 21, and the orthographic projection of the opening 21 in the plane where the display panel 1 is located is located in the first plane area 15. Along the direction perpendicular to the plane where the display panel 1 is located, the opening 21 at least penetrates the support component 2. The opening 21 has a first side wall 211 and a second side wall 212 that are relatively arranged. The distance between the orthographic projection of the first side wall 211 on the plane where the display panel 1 is located and the bending area 14 is smaller than the distance between the orthographic projection of the second side wall 212 on the plane where the display panel 1 is located and the bending area 14, that is, the orthographic projection of the first side wall 211 on the plane where the display panel 1 is located is closer to the bending area 14 than the orthographic projection of the second side wall 212 on the plane where the display panel 1 is located, so as to limit the relative positions of the first side wall 211 and the second side wall 212.

[0082] In the above embodiment, the distance between the orthogonal projection of the first side wall 211 on the plane where the display panel 1 is located and the bending zone 14 refers to: the distance between the orthogonal projection of the first side wall 211 on the plane where the display panel 1 is located and the bending axis in the bending zone 14. It should be understood that the orthogonal projection of the first side wall 211 on the plane where the display panel 1 is located is a straight line or a projection plane, which is in the same plane as the bending axis and parallel to each other. The distance value between the orthogonal projection of the first side wall 211 on the plane where the display panel 1 is located and the bending axis can be one or more. Based on the same reasoning, the orthogonal projection of the second side wall 212 on the plane where the display panel 1 is located is a straight line or a projection plane, and the distance value between the second side wall 212 and the bending axis can be one or more.

[0083] The camera assembly 3 includes a camera body 31, which is located in the opening 21. The distance between the camera body 31 and the first side wall 211 is distributed in a stepped manner along the direction perpendicular to the plane where the display panel 1 is located. This arrangement allows the distance between the camera body 31 and the support assembly 2 to reserve a certain position misalignment for the display module 10 during the bending process, and to compensate for the slippage of the support assembly 2 during the bending and movement process, thereby avoiding interference between the camera body 31 and the support assembly 2, and improving the shooting quality of the camera body 31. At the same time, this stepped position misalignment can reduce the opening area in the support assembly 2, thereby ensuring the mechanical properties of the support assembly 2. It can be understood that the stepped distribution means that the distance between the camera body 31 and the first side wall 211 increases in sequence along the direction from the display panel 1 to the support assembly 2, or the distance between the camera body 31 and the first side wall 211 decreases in sequence along the direction from the display panel 1 to the support assembly 2.

[0084] Specifically, the distance between the camera body 31 and the first side wall 211 of the present application is distributed in a stepped manner, including three different situations. In the first situation, please continue to refer to Figure 2, the first side wall 211 of the opening 21 is distributed in a stepped manner, and the surface of the camera body 31 facing the display panel 1 is a flat surface; in the second case, please refer to Figure 4 , the surface of the camera body 31 facing the display panel 1 is distributed in a stepped manner, and the first side wall of the opening is arranged in a plane; in the third case, please refer to Figure 5 , the first side wall 211 of the opening 21 is distributed in a stepped manner, and the surface of the camera body 31 facing the display panel 1 is also distributed in a stepped manner, and the stepped distribution pattern of the first side wall 211 is opposite to the stepped distribution pattern of the surface of the camera body 31. The stepped distribution in the above three situations can provide a certain sliding space for the support assembly 2 during the bending process of the display module 10.

[0085] In this embodiment, during the bending process of the display module, the bending area 14, the first plane area 15 and the second plane area 16 are driven to move by the bending axis of the bending area 14. Therefore, the slippage of the area closer to the bending axis is greater. Therefore, during the bending process of the display module 10, the slippage between the first side wall 211 closer to the bending axis and the camera body 31 is larger, and the interference effect on the camera body 31 will also be greater.

[0086] In the embodiment of the present application, the distance between the camera body 31 and the first side wall 211 is 5 μm to 200 μm. For example, the distance between the camera body 31 and the first side wall 211 can be 5 μm, 10 μm, 30 μm, 50 μm, 80 μm, 100 μm, 150 μm, 180 μm, and 200 μm, etc. Within the above distance range, it is shown that the area of ​​the opening 21 of the present application is small, which can improve the mechanical properties of the support assembly 2 while improving the shooting quality of the camera body 31.

[0087] It can be understood that the display module 10 usually includes two cameras: a front camera and a rear camera. Since the setting of the rear camera does not affect the screen-to-body ratio of the display module, the camera body 31 of the present application specifically refers to the front camera.

[0088] In the present application, the specific structural form of the camera body 31 generally includes a lens assembly and an image sensor (not shown in the drawings). Compared with digital zoom, the optical zoom function of the camera is more important for improving the shooting effect. In order to achieve optical zoom, the camera needs to be equipped with multiple position-adjustable optical lenses to achieve the purpose of adjusting the focal length. Of course, the camera body 31 of the present application can also adopt other lens optical components (such as glass lenses) in the art, and the present application is not limited here.

[0089] In the embodiment of the present application, for the flexible display module, the flexible display panel includes two different bending forms, namely, inward bending and outward bending, so that the positions and connection relationships of the support component 2, the camera body 31, the first plane area 15 and the second plane area 16 will also be different. The following is an explanation of the two different cases in which the display module includes an inward-bending display module and an outward-bending display module, wherein the support component of the inward-bending display module is referred to as an inward-bending support component 4, and the support component of the outward-bending display module is referred to as an outward-bending support component 5.

[0090] Next, taking the first case where the support assembly adopts the first situation (the first side wall of the opening is distributed in a stepped manner, and the surface of the camera body 31 facing the display panel is flat) as an example, the structures of the inward-curved display module and the outward-curved display module are described in detail.

[0091] In the embodiment of the present application, the inward-bending display module 10 includes: an inward-bending support component 4, the inward-bending support component 4 includes an inward-bending opening 41, the orthographic projection of the inward-bending opening 41 in the plane where the display panel 1 is located is located in the first plane area 15, along the direction perpendicular to the plane where the display panel 1 is located, the inward-bending opening 41 at least penetrates the inward-bending support component 4, and the inward-bending opening 41 has an inward-bending first side wall 411 and an inward-bending second side wall 412 that are arranged oppositely. The display module 10 has a flattened state and an inward-bending state: Figure 7 As shown, in the flattened state, the first plane area 15 and the second plane area 16 are in the same plane. Figure 6 As shown, in the inward bending state, the first plane area 15 is located between the camera body 31 and the second plane area 16. In the flattened state, along the direction of the display panel 1 toward the inward bending support component 4, that is, along the negative direction of the Z-axis direction, the distance between the camera body 31 and the inward bending first side wall 411 decreases successively. Specifically, in the process of the display module 10 bending inward, the inward bending first side wall 411 of the inward bending support component 4 slides along the direction of the bending axis pointing to the first plane area 15, and the sliding amount of the inward bending first side wall 411 decreases successively along the direction of the display panel 1 toward the inward bending support component 4. It can be understood that the direction along the bending axis pointing to the first plane area 15 is the negative direction of the X-axis direction, and the direction along the display panel toward the inward bending support component 4 is the negative direction of the Z-axis. In the present application, by reducing the distance between the camera body 31 and the inward bending first side wall 411 successively along the Z-axis direction, the sliding amount of the inward bending first side wall 411 can be compensated, so that the inward bending support component 4 and the camera body 31 will not contact and interfere with each other, thereby improving the shooting quality of the camera body 31. At the same time, the present application makes corresponding position compensation for the distance between the camera body 31 and the inward-bending first side wall 411 and the slip amount of the inward-bending first side wall 411 during the inward-bending process, so that the area of ​​the inward-bending opening 41 of the inward-bending support component 4 is smaller, thereby ensuring the supporting performance of the inward-bending support component 4 for the display panel 1.

[0092] In the embodiment of the present application, along the X-axis direction, since the inward-bending second side wall 412 is farther away from the bending zone 14 than the inward-bending first side wall 411, when the display module 10 is bent, the slip amount of the inward-bending second side wall 412 is less than the slip amount of the inward-bending first side wall 411, that is, the inward-bending second side wall 412 has little or almost no effect on the camera body 31 in the inward-bending opening 41 during the bending process. Therefore, in the flattened state, along the display panel 1 toward the inward-bending support component 4, the distance between the inward-bending second side wall 412 and the camera body 31 can be successively increased (see Figure 8 ), or it can be successively smaller (see Fig. 9 ). It can be understood that a certain space needs to be reserved between the inwardly curved second side wall 412 and the camera body 31 to facilitate the sliding of the camera body 31 and the inwardly curved second side wall 412 during the bending process of the display module.

[0093] In the embodiment of the present application, the display module 10 further includes a middle frame 6, which is arranged on the side of the inner curved support component 4 away from the display panel 1. The inner curved support component 4 includes an inner curved edge layer 43 facing the side of the middle frame 6 and an inner curved inner layer 42 away from the middle frame 6. In the flattened state, along the direction from the display panel 1 to the inner curved support component 4, in the inner curved edge layer 43, the distance between the camera body 31 and the inner curved second side wall 412 is greater than the distance between the camera body 31 and the inner curved first side wall 411. For details, please refer to Fig.10 The display module 10 of the present application includes a display panel 1, an inward-curved support component 4 and a middle frame 6 which are stacked in sequence, wherein the inward-curved support component 4 includes an inward-curved inner layer 42 and an inward-curved edge 43, and the inward-curved edge 43 is arranged between the inward-curved inner layer 42 and the middle frame 6. In the inward-curved edge layer 43, the distance W2 between the camera body 31 and the inward-curved second side wall 412 is greater than the distance W1 between the camera body 31 and the inward-curved first side wall 411. Such an arrangement allows the display module 10 to provide a reserved space for the movement of the camera body 31 during the inward bending process, thereby preventing the camera body 31 from contacting the inward-curved support component 4 and affecting the photo quality of the camera body 31.

[0094] In the embodiment of the present application, the outward-bending display module includes an outward-bending support component 5, the outward-bending support component 5 includes an outward-bending opening 51, the orthographic projection of the outward-bending opening 51 in the plane where the display panel 1 is located is located in the first plane area 15, along the plane direction where the display panel 1 is located, the outward-bending opening 51 at least passes through the outward-bending support component 5, and the outward-bending opening 51 has an outward-bending first side wall 511 and an outward-bending second side wall 512 that are arranged oppositely. The display module 10 has a flattened state and an outward-bending state: in the flattened state, the first plane area 15 and the second plane area 16 are in the same plane, and in the outward-bending state, as shown in FIG. Fig.11 The camera body 31 is located between the first plane area 15 and the second plane area 16. In the flattened state, please refer to Fig.12 , along the direction of the display panel 1 toward the outward bending support component 5, that is, along the negative direction of the Z-axis direction, the distance between the camera body 31 and the outward bending first side wall 511 increases successively. Specifically, in the process of the display module 10 bending outward, the outward bending first side wall 511 of the outward bending support component 5 slides along the direction of the bending axis pointing to the first plane area 15, and the sliding amount of the outward bending first side wall 511 increases successively along the direction of the display panel 1 toward the outward bending support component 5. It can be understood that the direction along the bending axis pointing to the first plane area 15 is the negative direction of the X-axis direction, and the direction along the display panel 1 toward the outward bending support component 5 is along the negative direction of the Z-axis. The present application can compensate for the sliding amount of the outward bending first side wall 511 by increasing the distance between the camera body 31 and the outward bending first side wall 511 successively along the negative direction of the Z-axis direction, so that the outward bending support component 5 and the camera body 31 will not contact and interfere with each other, thereby improving the shooting quality of the camera body 31. At the same time, the present application makes corresponding position compensation for the distance between the camera body 31 and the first outward-bending side wall 511 and the slip amount of the first outward-bending side wall 511 during the outward-bending process, so that the area of ​​the outward-bending opening 51 of the outward-bending support assembly 5 is smaller, thereby ensuring the supporting performance of the outward-bending support assembly 5 for the display panel.

[0095] In the embodiment of the present application, along the X-axis direction, since the outer curved second side wall 512 is farther away from the bending area 14 than the outer curved first side wall 511, when the display module is bent, the sliding amount of the outer curved second side wall 512 is less than the sliding amount of the outer curved first side wall 511, that is, the outer curved second side wall 511 has little or almost no effect on the camera body 31 in the outer curved opening 51 during the bending process. Therefore, in the flattened state, along the direction perpendicular to the plane where the display panel 1 is located, the distance between the outer curved second side wall 512 and the camera body 31 can be successively increased or decreased. It can be understood that a certain space needs to be reserved between the outer curved second side wall 512 and the camera body 31 to facilitate the sliding of the camera body 31 and the outer curved second side wall 511 during the bending process of the display module.

[0096] In the embodiment of the present application, the display module further includes a middle frame 6, which is arranged on the side of the outward curved support component 5 away from the display panel 1. The outward curved support component 5 includes an outward curved edge layer 53 facing the side of the middle frame 6 and an outward curved inner layer 52 away from the middle frame 6. In the flattened state, in the outward curved edge layer 53 of the outward curved support component 5, the distance between the camera body 31 and the outward curved second side wall 512 is greater than the distance between the camera body 31 and the outward curved first side wall 511. For details, please refer to Fig.12The display module 10 of the present application includes a display panel 1, an outward bending support component 5 and a middle frame 6 which are stacked in sequence, wherein the outward bending support component 5 includes an outward bending inner layer 52 and an outward bending edge layer 53, and the outward bending edge layer 53 is arranged between the outward bending inner layer 52 and the middle frame 6. In the outward bending edge layer 53, the distance W4 between the camera body 31 and the outward bending second side wall 512 is smaller than the distance W3 between the camera body 31 and the outward bending first side wall 511. Such an arrangement enables the display module to reserve space for the movement of the camera body 31 during the process of bending outward, thereby avoiding contact between the camera body 31 and the outward bending support component 5 to affect the photo quality of the camera body 31.

[0097] In the embodiments of this application, please refer to Fig.13 The support assembly 2 includes a buffer layer 22, a support layer 23, an electromagnetic layer 24 and a cushion layer 25 stacked in a direction perpendicular to the plane where the display panel 1 is located, and the opening 21 penetrates the buffer layer 22, the support layer 23, the electromagnetic layer 24 and the cushion layer 25. Specifically, the buffer layer 22, the support layer 23 and the electromagnetic layer 24 are the above-mentioned inner curved inner layer 42 or the outer curved inner layer 52, and the cushion layer 25 is the above-mentioned inner curved edge 43 or the outer curved edge layer 53. Among them, the buffer layer 22, the support layer 23, and the electromagnetic layer 24 can be adjusted in order or increased or decreased according to the needs of the display module.

[0098] In the above embodiment, the material of the buffer layer 22 includes at least one of foam, polyurethane, silicone rubber and butyl rubber. The above material is arranged between the support layer 23 and the display panel to play a buffering role to prevent the display panel from being affected during use. The material of the electromagnetic layer 24 includes electromagnetic infection treatment material, such as ferrite material, which can absorb electromagnetic interference signals and convert them into heat for volatilization. In the embodiment of the present application, the material of the support layer 23 includes metal or carbon material, which is conducive to improving the overall structural strength of the display module. Exemplarily, the metal can be aluminum alloy, copper alloy and stainless steel. The material of the cushion layer 25 includes thermal conductive silicone grease or heat dissipation resin. The cushion layer 25 is in contact with the middle frame 6. The heat generated by the display module can be transferred to the middle frame 6 of the display module through the cushion layer 25. The middle frame 6 of the display module is in contact with the external environment. Such a setting is conducive to improving the heat dissipation effect of the display module.

[0099] In the embodiment of the present application, an adhesive layer is provided between the display panel 1 and the buffer layer 22, between the buffer layer 22 and the support layer 23, and between the support layer 23 and the electromagnetic layer 24 (the adhesive layer is not shown in the drawings). The material of the adhesive layer can be a PSA (Pressure Sensitive Adhesive) adhesive layer. PSA has high adhesion, small curing shrinkage, strong water resistance and high temperature resistance, and excellent lamination gap filling. Therefore, the PSA optical adhesive layer is used to connect the various film layers, which can extend the service life and enhance the reliability of the display module. Of course, other materials of adhesive such as OCA (Optically Clear Adhesive) can also be used, and this application is not limited here.

[0100] In the embodiments of this application, please continue to refer to Figure 1 The first plane area 15 has a sensing area 17, and the sensing area 17 has a central axis perpendicular to the surface where the first plane area 15 is located. The camera assembly 3 also includes a support plate 32, and the support plate 32 is arranged between the camera body 31 and the middle frame 6. The camera body 31 is installed on the support plate 32. The display module 10 also includes a moving module 7, and the moving module 7 is arranged between the supporting assembly and the middle frame 6. The moving module 7 is used to drive the support plate 32 to move so that the central axis of the camera body 31 corresponds to the central axis of the sensing area 17. For details, please refer to Fig.14 In this application, a moving module 7 is provided at the bottom of the camera assembly 3, and the moving module 7 drives the support plate 32 to move, thereby driving the camera body 31 to move, so as to ensure that the central axis of the camera body 31 corresponds to the central axis of the sensing area 17 during the bending process of the display module 10, thereby compensating for the position change caused by the film layer displacement of the inner bending support assembly 4 during the bending process of the display panel 1, and further improving the shooting quality of the camera body 31. Fig.14 In the figure, the block diagram shown by the dotted line in the display panel 1 is the area corresponding to the camera body 31 before the movement, and the block diagram shown by the solid line in the display panel 1 is the position corresponding to the camera body 31 after the movement by the mobile module, that is, the position of the sensing area 17 on the display panel 1, and the direction indicated by the arrow is the moving direction of the camera body 31. The setting of the mobile module 7 of the present application can accurately adjust the display panel 1, the support assembly 2 and the camera body 31 when the relative position changes unknown during the bending process, so that the central axis of the camera body 31 corresponds to the central axis of the sensing area 17, which solves the problem that the existing camera body 31 has a low effect of adjusting the quality of the captured image through algorithm compensation.

[0101] It should be noted that the central axis of the camera body 31 and the central axis of the sensing area 17 are not actual structures of the display module 10 , but are only concepts proposed to illustrate the movement process of the camera body 31 .

[0102] In the embodiments of this application, please continue to refer to Fig.14 The moving module 7 includes a pushing module 71, which is arranged on at least one side of the support plate 32. The pushing module 71 is used to drive the support plate 32 to move along a first direction, wherein the first direction is parallel to the plane where the display panel 1 is located. Specifically, for the inward-bending display module 10, during the inward bending process, the bending degree of the inward-bending support assembly 4 increases as the bending angle of the display module 10 increases, so that the inward-bending first side wall 411 of the inward-bending support assembly 4 moves along the negative direction of the X-axis direction. In order to avoid the influence of the inward-bending first side wall 411 on the camera body 31 during the movement, the pushing module 71 is arranged on the side of the support plate 32 facing the positive direction of the X-axis direction. The pushing module 71 can drive the support plate 32 to move along the negative direction of the X-axis direction, so that the central axis of the camera body 31 corresponds to the central axis of the sensing area 17, thereby improving the shooting quality of the camera body 31 during the inward bending process. For the outward-bending display module 10, please refer to Fig.15 The degree of bending of the outward bending support component 5 also increases with the increase of the bending angle of the display module, so that the outward bending first side wall 511 of the outward bending support component 5 moves along the positive direction of the X-axis direction. In order to avoid the influence of the outward bending first side wall 511 on the camera body 31 during the movement, the push module 71 is arranged on the side of the support plate 32 facing the negative direction of the X-axis direction. The push module 71 can drive the support plate 32 to move along the positive direction of the X-axis direction, so that the central axis of the camera body 31 corresponds to the central axis of the sensing area 17, thereby improving the shooting quality of the camera body 31 during the outward bending process. Fig.15 In the figure, the dotted line in the display panel 1 is the area corresponding to the camera body 31 before the movement, and the solid line in the display panel 1 is the position corresponding to the camera body 31 after the camera body 31 is moved by the mobile module, which is the position of the sensing area 17 on the display panel 1. The direction indicated by the arrow is the moving direction of the camera body 31.

[0103] In the embodiment of the present application, the movable module 7 further includes an adjustment module 72, which is disposed between the support plate 32 and the middle frame 6. The adjustment module 72 is used to drive the support plate 32 to rotate around a second direction, wherein the second direction is perpendicular to the first direction, and a plane formed by the first direction and the second direction is parallel to a plane where the display panel 1 is located. Specifically, taking the inwardly curved display module 10 as an example, refer to Fig.16When the display module 10 is bent, the surface flatness of the display panel 1 changes after long-term use, so that the surface of the display panel 1 is tilted downward from the edge to the center. The present application uses an adjustment module 72 to drive the support plate 32 to rotate around the second direction, so that the central axis of the camera body 31 corresponds to the central axis of the sensing area 17, thereby improving the shooting quality of the camera body 31 during the bending process. In this embodiment, the second direction is the Y-axis direction, and the plane formed by the X-axis direction and the Y-axis direction is parallel to the plane where the display panel 1 is located. Fig.16 In the figure, the block diagram shown by the dotted line in the display panel 1 is the area corresponding to the camera body 31 before moving, the camera body 31 shown by the dotted line is the camera body before moving, and the block diagram shown by the solid line in the display panel 1 is the position corresponding to the camera body 31 after moving by the mobile module, that is, the position of the sensing area 17 on the display panel 1.

[0104] Therefore, the present application sets a pushing module 71 to drive the support plate 32 to move in parallel to the plane where the display panel 1 is located, and sets an adjustment module 72 to drive the support plate 32 to rotate around the second direction, so that the central axis of the camera body 31 installed on the support plate 32 corresponds to the central axis of the sensing area 17, thereby improving the shooting quality of the camera body 31 during the bending process. It can be understood that the movable module 7 of the present application can be applicable to both inward-bending display modules and outward-bending display modules.
