[0005] In order to solve the above technical problem, the present application is implemented as follows:

[0006] In a first aspect, the present application discloses a display screen module, comprising: a cover plate, a polarizing plate and a screen body panel which are stacked along a first direction; wherein,

[0007] The cover plate and the polarizing plate are further connected with an adhesive layer which at least partially extends to a target side of the polarizing plate and the screen body panel along a second direction and covers the target side of the polarizing plate and the screen body panel, wherein the first direction is the thickness direction of the display screen module, and the second direction intersects the first direction.

Since the target side of the screen body panel is covered by the adhesive layer, the screen body panel is not easily penetrated and corroded by external liquid impurities, effectively improving the reliability of the screen body panel and ensuring the use function of the display screen module. In addition, the adhesive layer directly extends to the target side of the polarizing plate and the screen body panel to cover the screen body panel, without the need for separately arranging other sealing structures, thus maintaining the original structure of the display screen module and facilitating processing.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0020] In the description of the present application, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0021] In the description of the present application, it needs to be understood that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] The display screen module, as an important structure in electronic devices, can convert digital signals into image and text information and display them on the display screen, providing information interaction function for users. However, in actual application, there is a gap between the display screen module and the frame of the electronic device, so that the side surface of the display screen module is easily penetrated and corroded by external impurities such as liquid, water vapor, etc., thereby causing the display screen module to be damaged, affecting the display effect of the display screen module, and even causing the display screen module to malfunction in severe cases. For example, when the user pastes a UV glue tempered film on the display screen of the electronic device, since the UV glue has a certain fluidity, in the case that the receiver hole between the display screen and the frame is not shielded or sealed, the UV glue on the surface of the display screen may flow to the inside of the electronic device through the gap, and corrode the display screen, causing black spots on the display screen, and even causing the display screen to fail in severe cases.

[0023] In the related art, in order to prevent the UV glue from entering the inside of the device and corroding the display screen during the process of pasting the UV glue tempered film, the display screen near the receiver hole is usually separately glued, but such structure has high requirements for the control of the amount of glue and the width and height of the glue, which also increases the precision requirements for the glue equipment. In this way, separate equipment, manpower and resources are required, which is less economical.

[0024] However, in the display screen module provided by the present application, the covering of the screen body panel can be realized by lengthening the adhesive layer between the cover plate and the polarizing sheet, which has good protection effect, can be realized under the original production conditions, is simple to operate, and is more economical.

[0025] The display module provided in this application embodiment will be further described in detail below with reference to the accompanying drawings and specific embodiments. In this application embodiment, the first direction is the thickness direction of the display module, and the second direction is the length direction or width direction of the display module. Figures 1 to 5 As shown, the direction indicated by arrow Z is the first direction, and the direction indicated by arrow X is the second direction.

[0026] Reference Figure 5 This is a schematic diagram of the structure of a display module provided in an embodiment of this application, as shown below. Figure 5 As shown, the display module in this embodiment may specifically include: a cover plate 10, a polarizer 30, and a screen panel 40 stacked along the first direction Z; wherein, an adhesive layer 20 is connected between the cover plate 10 and the polarizer 30, and the adhesive layer 20 extends at least partially to the target side of the polarizer 30 and the screen panel 40 along the second direction X, and covers the target side of the polarizer 30 and the screen panel 40. The adhesive layer 20 can be used to connect the cover plate 10 and the polarizer 30 into one unit. At the same time, the portion of the adhesive layer 20 extending to the target side of the polarizer 30 and the screen panel 40 can cover the target side of the polarizer 30 and the screen panel 40 to prevent external impurities from corroding the screen panel 40.

[0027] Specifically, the cover plate 10, polarizer 30, and screen panel 40 are stacked along the first direction Z. The cover plate 10 can be a glass cover plate, located on the surface of the display module, and is used to protect the internal structure of the display module from damage such as impacts and scratches. Simultaneously, the glass cover plate 10 has good light transmittance, ensuring that users can clearly see the content displayed on the screen panel 40. The polarizer 30 is used to reduce reflections and suppress glare, while also filtering out unpolarized light to enhance the display contrast, thereby improving the clarity and visual comfort of the display. The screen panel 40 can be used to display images, text, and other information.

[0028] Furthermore, it should be noted that the display module may include multiple sides, and the screen panel 40 within the display module also includes multiple sides. In practical applications, depending on the functional requirements of the electronic device, the screen panel 40 may tend to bend away from the cover plate 10. Therefore, different sides of the display module can have different structures. For example, since the screen panel 40 typically has a display area and a non-display area, in order to reduce the screen ratio of the non-display area, the screen panel 40 can be configured as a flexible display, and the non-display area can be bent. Figures 1 to 5As shown, in the display screen module, the screen body panel 40 on the left side of the display screen module is in a U-shaped structure and the end thereof is away from the edge of the cover plate 10, and thus is not easy to be penetrated and eroded by external impurities. The screen body panel 40 on the right side of the display screen module is in a straight plate structure and the end thereof is close to the edge of the cover plate 10, and thus is more likely to be penetrated and eroded by external impurities. The target side of the screen body panel 40 should be the side that is easy to be penetrated and eroded by external impurities. In actual application, the target side of the screen body panel 40 can be flexibly determined according to the structural characteristics of the display screen module. In the embodiment of the present application, the target side of the polaroid 30, the target side of the support 50 and the target side of the screen body panel 40 are on the same side. Figures 1 to 5 the right side of the display screen module along the second direction X.

[0029] In the embodiment of the present application, the adhesive layer 20 is arranged between the cover plate 10 and the polaroid 30 to realize the connection between the cover plate 10 and the polaroid 30. In addition, the adhesive layer 20 also extends at least partially to the target side of the polaroid 30 and the screen body panel 40 and covers the target side of the polaroid 30 and the screen body panel 40. Since the target side of the screen body panel 40 is covered by the adhesive layer 20, the screen body panel 40 is not easy to be penetrated and eroded by external liquid impurities, effectively improving the reliability of the screen body panel 40 and ensuring the use function of the display screen module. In addition, the adhesive layer 20 extends directly to the target side of the polaroid 30 and the screen body panel 40 to cover the screen body panel 40, and no other sealing structure needs to be separately arranged on the structure, maintaining the original structure of the display screen module and facilitating processing.

[0030] The adhesive layer 20 can include two adhesive surfaces arranged away from each other, as shown in the following figure. Figure 1 As shown, in the existing electronic device, one of the adhesive surfaces of the adhesive layer 20 is connected with the cover plate 10, and the other adhesive surface is connected with the polaroid 30, so as to connect the cover plate 10 and the polaroid 30 into one body.

[0031] Optionally, the adhesive layer 20 includes a first connection area 21 and a second connection area 22. The first connection area 21 is connected between the cover plate 10 and the polaroid 30, and the second connection area 22 is exposed to the polaroid 30. The side of the second connection area 22 away from the polaroid 30, the screen body panel 40 and the support 50 is a non-adhesive surface, so as to reduce the adhesion of the adhesive layer 20 to impurities in the environment.

[0032] In the embodiment of the present application, as shown in the following figure, Figure 3As shown, the length of the adhesive layer 20 is extended in the direction of the target side of the screen body panel 40 along the second direction X, so that the adhesive layer 20 can be at least partially exposed to the polarizer 30, wherein the first connecting area 21 is connected between the cover plate 10 and the polarizer 30, and the second connecting area 22 is exposed to the polarizer 30, and the two side surfaces of the first connecting area 21 along the first direction Z are both adhesive surfaces, for realizing the connection between the cover plate 10 and the polarizer 30, maintaining the structural stability and durability of the display screen module; as shown, Figure 4 As shown, the second connecting area 22 is bent from the first connecting area 21 to the target side of the screen body panel 40, as shown, Figure 5 As shown, the second connecting area 22 is finally attached to and connected to the target side of the screen body panel 40, covering the target side of the screen body panel 40, wherein one side surface of the second connecting area 22 along the second direction X close to the target side of the polarizer 30, the screen body panel 40 and the support 50 is an adhesive surface, and the other side is a non-adhesive surface. It should be understood that the design of the non-adhesive surface can reduce the adhesion of particles, dust and the like in the environment, and can also avoid unintended bonding between the display screen module and other components of the electronic device during assembly of the display screen module and the electronic device, ensuring assembly efficiency and quality.

[0033] In practical applications, the size of the adhesive layer 20 can be selected according to the specific structure of the display screen module to ensure that the connection requirements of the cover plate 10 and the polarizer 30 are met, and the covering requirements of the target side of the screen body panel 40 are met. It can be understood that since the cover plate 10 and the polarizer 30 of the electronic device have an adhesive layer 20 between them, in the embodiment of the present application, the target side of the screen body panel is shielded and covered by extending the length of the adhesive layer 20. During assembly, only the second connecting area 22 of the adhesive layer 20 is brought up by using the original roller belt, and the polarizer 30 and the target side of the screen body panel 40 are attached and covered.

[0034] In the embodiment of the present application, the adhesive layer 20 is provided between the cover plate 10 and the polarizer 30, and the first connecting area 21 of the adhesive layer 20 can be used to realize the connection between the cover plate 10 and the polarizer 30. In addition, the second connecting area 22 of the adhesive layer 20 also extends to the target side of the polarizer 30 and the screen body panel 40, and covers the target side of the polarizer 30 and the screen body panel 40. Since the target side of the screen body panel 40 is covered by the second connecting area 22 of the adhesive layer 20, the screen body panel 40 is not easily penetrated and corroded by external liquid impurities, effectively improving the reliability of the screen body panel 40 and ensuring the use function of the display screen module.

[0035] Optionally, the adhesive layer 20 is an optical adhesive layer, which has a certain flexibility, so that a certain deformation can occur, so that the adhesive layer 20 of the second connecting area 22 can extend in the direction of the polarizer 30 along the first direction Z until covering the target side of the polarizer 30 and the screen body panel 40.

[0036] It should be noted that the optical adhesive (Optical Clear Adhesive, OCA) is a special adhesive for bonding transparent optical elements, and its curing process usually needs to be realized by UV curing. UV curing is to irradiate a certain intensity of ultraviolet light to instantly cure inks, coatings, adhesives and other related chemicals, which has the characteristics of rapidness and high efficiency. The optical adhesive has various states, including liquid optical adhesive and solid optical adhesive. In the embodiments of the present application, the optical adhesive layer needs to be bent at the end of the polarizer 30. In actual application, the bending operation can be performed before the optical adhesive is cured to meet the corresponding bending and deformation requirements. After the optical adhesive layer is deformed to the target position, the optical adhesive layer can be cured to meet the structural strength. The curing process of the optical adhesive not only can improve the bonding strength of the optical adhesive, but also can reduce the curing shrinkage rate and prevent blistering, thereby improving the process effect. In specific application, the second connecting area 22 of the optical adhesive layer can be lifted by using a roller in the full bonding process of the cover plate 10 and the polarizer 30, so that it is away from the cover plate 10 and bent towards the direction of the polarizer 30 and the screen body panel 40, and finally covers the target side of the polarizer 30 and the screen body panel 40.

[0037] Optionally, the display screen module further comprises a support 50 connected to the side of the screen body panel 40 away from the polarizer 30, and the adhesive layer 20 further extends to the target side of the support 50 along the second direction X and covers the target sides of the polarizer 30, the screen body panel 40 and the support 50 in turn. The provision of the support 50 can provide a certain support for the screen body panel 40, which not only can reduce the risk of damage to the screen body panel 40, but also can provide a certain support for the bending of the non-display area of the screen body panel 40.

[0038] Specifically, the support 50 comprises a support film 51 and a composite adhesive tape 52, wherein the support film 51 is connected to the side of the screen body panel 40 away from the polarizer 30, and the composite adhesive tape 52 is connected to the side of the support film 51 away from the screen body panel 40. In actual application, the support film 51 can be used to support the screen body panel 40 and provide a certain buffering effect for the screen body panel 40 to resist external forces, and the composite adhesive tape 52 can be used to heat dissipation, electromagnetic shielding, buffering external forces and preventing light leakage of the screen body panel 40, so as to better protect the screen body panel 40.

[0039] In the embodiments of the present application, the second connecting area 22 of the adhesive layer 20 also extends to the target side of the support member 50 and covers the target side of the support member 50. Since the adhesive layer 20 covers the polarizing sheet 30, the screen panel 40 and the target side of the support member 50 in sequence, the polarizing sheet 30 and the support member 50 on both sides of the screen panel 40 along the thickness direction can be effectively protected, which is conducive to improving the protection of the screen panel 40 from both sides. In addition, since the support film 51 is in a bonded relationship with the screen panel 40, the adhesive layer 20 extends to cover the support member 50, so that the bonding gap between the support film 51 and the screen panel 40 is protected, thereby preventing external impurities such as liquid and dust from invading the screen panel 40 through the gap, and avoiding delamination between the screen panel 40 and the support film 51.

[0040] As shown in Figure 2 , the target side of the screen panel 40 is recessed in the second direction X to the target side of the polarizing sheet 30 and the target side of the support member 50 to form a groove 60, and the adhesive layer 20 fills the groove 60.

[0041] Specifically, the groove 60 is formed by the bottom surface of the polarizing sheet 30 along the first direction Z, the side surface of the screen panel 40 along the second direction X and the top surface of the support member 50 along the first direction Z, and the adhesive layer 20 fills the groove 60. The groove 60 can be used to accommodate part of the adhesive layer 20, thereby increasing the connection effect between the adhesive layer 20 and the screen panel 40. In the embodiments of the present application, with reference to the structure of the display screen module, along the first direction Z, the side close to the cover plate 10 is the top surface of the display screen module, and the side away from the cover plate 10 is the bottom surface of the display screen module. Further, the bottom surface of the polarizing sheet 30 refers to the side of the polarizing sheet 30 away from the cover plate 10 along the first direction Z, and the top surface of the support member 50 refers to the side of the support member 50 close to the cover plate 10 along the first direction Z. The two sides of the display screen module along the second direction X are the side surfaces of the display screen module. Similarly, the side surface of the screen panel 40 refers to the side surface of the screen panel along the second direction X.

[0042] In specific applications, based on the display screen module shown in Figure 1 , the polarizing sheet 30 and the support member 50 can be widened along the second direction X to form the groove 60, or the screen panel 40 can be narrowed along the second direction X to form the groove 60, or the polarizing sheet 30 and the support member 50 can be widened and the screen panel 40 can be narrowed to form the above-mentioned groove 60. The forming method of the groove 60 is not limited in the embodiments of the present application, and in actual applications, the groove 60 can be designed according to the structural characteristics of the components of the electronic device.

[0043] In some optional embodiments of the present application, the target side of the polarizer 30 is aligned with the target side of the support 50 along the first direction Z, and the target side of the screen panel 40 is recessed in the target side of the polarizer 30 and the target side of the support 50 along the second direction X, and forms the above-mentioned groove 60.

[0044] Specifically, the target side of the polarizer 30 protrudes beyond the screen panel 40 along the second direction X, the target side of the support 50 is aligned with the target side of the polarizer 30 in the height direction of the electronic device, and the target side of the support 50 also actually protrudes beyond the screen panel 40 along the length and / or width direction of the electronic device, and together with the screen panel 40 and the support 50, forms the above-mentioned groove 60 for filling the optical adhesive layer. In this way, the polarizer 30 and the support 50 that protrude beyond the screen panel 40 not only serve to form the groove 60, but also can play a certain supporting and protecting role for the screen panel 40. When an external force collides with the display screen module, the impact force is first transmitted to the polarizer 30 and the support 50, thereby protecting the recessed screen panel 40 from collision and ensuring the reliability of the screen panel 40. In addition, since the target side of the polarizer 30 is aligned with the target side of the support 50, the groove 60 can have a symmetrical structure, and the optical adhesive filled in the groove 60 has more balanced structural strength on both sides close to the polarizer 30 and close to the support 50 in the thickness direction of the electronic device, thereby improving the protection of the screen panel 40 by the adhesive layer 20 at the groove 60.

[0045] Further, the size of the groove 60 along the second direction X is related to the extensibility of the adhesive layer 20. The size of the groove 60 along the first direction Z is the thickness dimension of the screen panel 40, and by designing the size of the groove 60 along the second direction X, sufficient space can be provided for the adhesive layer 20 to adapt to the volume change during the curing process. Alternatively, when the adhesive layer 20 has poor extensibility, the size of the groove 60 along the second direction X can be appropriately reduced to ensure the tightness of the adhesive layer 20 and the groove 60, reduce the risk of interfacial gap between the adhesive layer 20 and the inner wall of the groove 60, and reduce the peeling risk caused by the interfacial gap, thereby ensuring the structural strength of the display screen module. In addition, the size of the groove 60 in the second direction X should be controlled within a small range, such as 0.5mm-1mm, to ensure that the black border of the display screen module is controlled within a predetermined size.

[0046] The adhesive layer 20 can select a flexible optical glue. The optical glue can be deformed before curing, so that the deformation is adapted to the shape of the groove 60, so as to fill in the groove 60. It can be understood that, since the adhesive layer 20 covers the polarizing plate 30, the screen panel 40 and the support 50 at the same time, and the groove 60 is arranged to make the adhesive layer 20 fill the groove 60, the connection effect between the adhesive layer 20 and the whole of the polarizing plate 30, the screen panel 40 and the support 50 is better. Further, since the optical glue layer has a certain deformation ability, the outer surface of the optical glue layer can remain flat while the optical glue layer deforms into the groove 60. In this way, the relative size of the optical glue layer and the screen panel 40 in the length or width direction of the electronic device is larger, and the protection function of the screen panel 40 is stronger.

[0047] Optionally, the cover plate 10 is provided with a sound hole, and the adhesive layer 20 covers the target side of the screen panel 40 at least at a position opposite to the sound hole.

[0048] In actual application, the sound hole of the receiver can be arranged on the cover plate 10 and penetrate the cover plate 10 in the thickness direction. In this structure, external impurities such as water vapor and liquid can easily pass through the cover plate 10 through the sound hole and enter the inside of the electronic device. If the display screen module does not have a protection structure, these impurities can easily corrode the display screen module and cause structural damage and functional failure. Therefore, the second connection area 22 can be arranged at a position opposite to the sound hole. Since the second connection area 22 can cover the polarizing plate 30 and the screen panel 40, the adhesive layer 20 can play a protection role on the screen panel 40 near the sound hole.

[0049] It should be noted that the electronic device has at least four side edges, each of which is opposite to the side of the display screen module. In the embodiment of the present application, the position opposite to the sound hole refers to a preset area opposite to the sound hole along the length or width direction of the display screen module. The length of the preset area can be the length of the sound hole, or can be greater than the length of the sound hole, so as to increase the area of the adhesive layer 20 covering the screen panel 40 and further ensure the protection area of the adhesive layer 20 on the screen panel 40.

[0050] In summary, the display screen module provided by the embodiment of the present application can have at least the following advantages:

[0051] In the embodiments of the present application, an adhesive layer is arranged between the cover plate and the polarizer to realize the connection between the cover plate and the polarizer. In addition, the adhesive layer also extends at least partially to the target side of the screen body panel and covers the target side of the screen body panel. Since the target side of the screen body panel is covered by the adhesive layer, the target side of the screen body panel is not easy to be penetrated and corroded by external liquid impurities, thereby effectively improving the reliability of the screen body panel and ensuring the use function of the display screen module. In addition, the adhesive layer directly extends to the target side of the screen body panel to cover the screen body panel, and no other sealing structure needs to be separately arranged in the structure, thereby maintaining the original structure of the display screen module and facilitating processing.

[0052] The embodiments of the present application also provide an electronic device including the display screen module in any of the above. The electronic device can be at least one of a smart phone, a tablet computer, a wearable device, etc., and the present application does not make specific limitations on this.

[0053] Further, the electronic device further includes a frame, and the frame is provided with a key hole. The adhesive layer 20 covers the target side of the screen body panel 40 at least at a position opposite to the key hole.

[0054] Specifically, the frame of the electronic device includes four side edges, each of which is opposite to a side of the display screen module. In the embodiments of the present application, the position opposite to the key hole refers to a preset region where the side of the display screen module is opposite to the key hole along the length direction or the width direction of the electronic device. The length of the preset region can be the length of the key hole or can be greater than the length of the key hole, so as to increase the area of the adhesive layer 20 covering the screen body panel 40 and further ensure the protection area of the adhesive layer 20 to the screen body panel 40.

[0055] Optionally, the cover plate 10 and the frame enclose the sound outlet hole, and the adhesive layer 20 covers the target side of the screen body panel 40 at least at a position opposite to the sound outlet hole.

[0056] In actual application, the positions of the receiver sound outlet holes in different electronic devices can also be different. In an optional embodiment, the sound outlet hole of the receiver can be arranged between the cover plate 10 and the frame to form a micro-gap sound outlet. In this structure, as described above, the position opposite to the sound outlet hole refers to a preset region where the target side of the display screen module is opposite to the sound outlet hole along the length direction or the width direction of the electronic device. The length of the preset region can be the length of the sound outlet hole or can be greater than the length of the sound outlet hole, so as to increase the area of the adhesive layer 20 covering the screen body panel 40 and further ensure the protection area of the adhesive layer 20 to the screen body panel 40.
