[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] At present, AM-OLED has entered thousands of households with its own characteristics of being light, foldable, high color gamut, and high contrast. It has become the display screen of choice for terminal device manufacturers such as mobile phones and laptops. It has gradually penetrated into the screen market and its market share has continued to increase.

[0039] However, due to the short research time of AM-OLED (English: Active-matrix organic light-emitting diode, Chinese translation: active matrix organic light-emitting diode or active matrix organic light-emitting diode) screen, AM-OLED screen has always had the problem of low strength. The low strength of the flexible screen is mainly because the screen itself is in a flexible state, which is easy to deform and cause damage and rupture of the internal film layer, especially the dense inorganic film layer. When producing AM-OLED screens, they are usually made into panel motherboards according to process requirements, and then cut into small screens according to the size of electronic devices. Therefore, it is easy to break when the deformation is large or the cutting process. For example, in the production process of the screen production factory, there are actions such as flexible screen cutting, machine handling, and manual placement and detection. These actions are very likely to cause damage to the edge of the screen. The cracks on the edge will extend all the way to the inside of the screen, causing poor functionality. If the inorganic film layer has a slight crack that is not easy to detect before leaving the factory, it will gradually deteriorate after entering the market, causing the screen to fail, and then become a customer complaint.

[0040] In order to solve the above technical problems, the present disclosure provides a display panel and an electronic device, wherein the display panel has a first area and a second area located outside the first area, and a groove around the periphery of the first area is arranged in the second area, and the first inorganic film layer and part of the substrate in the first part and the second part are separated at the position of the groove by the groove, so that cracks in the second area cannot extend into the first area along the first inorganic film layer, thereby enhancing the stability of the display panel. At the same time, a blocking structure is filled in the groove to effectively prevent the stress in the local area of ​​the groove from increasing, resulting in changes in the internal structure of the first inorganic film layer and the substrate, and further causing the initiation and expansion of cracks. Therefore, filling the blocking structure in the groove can prevent the array substrate from stress concentration at the position of the groove, making it more reliable during use, thereby extending the service life of the display panel, and preventing the extension of cracks can improve the display effect of the display panel and enhance the user's visual experience.

[0041] An exemplary embodiment of the present disclosure provides a display panel such as Figure 1-Figure 7 As shown, the display panel includes an array substrate 1 and a blocking structure 2. The array substrate 1 includes a substrate 11 and at least one first inorganic film layer 12 disposed on the substrate 11, wherein the first inorganic film layer 12 completely covers the substrate 11. The first inorganic film layer 12 and the substrate 11 can be selected from suitable materials according to the design and performance requirements of the display panel, and no specific limitation is made in this embodiment. The array substrate 1 has a first area 101 and a second area 102 located outside the first area 101, and a groove 1021 is provided in the second area 102 around at least part of the periphery of the first area 101, that is, referring to Figure 7 , the first region 101 is arranged inside the second region 102, and the groove 1021 is arranged in the second region 102, wherein the groove 1021 may be arranged in a circle around the first region 101, or may be arranged on a part of the periphery of the first region 101, for example, the groove 1021 may be arranged in multiple sections along the periphery of the first region 101. In the second region 102, the groove 1021 penetrates each first inorganic film layer 12 and the bottom of the groove 1021 is located in the substrate 11, and the blocking structure 2 is arranged in the second region 102, and the blocking structure 2 fills the groove 1021.

[0042] For example, refer to Figure 1 After the panel motherboard has completed the laying process of each layer, it is necessary to cut the panel motherboard according to the size required by the electronic device to obtain multiple independent display panels. The cutting position is Figure 1At the position of the middle cutting line 8, when the panel motherboard is cut along the cutting line 8, cracks will be generated in the first inorganic film layer 12, and the cracks will spread to the first area 101, thereby causing damage to the display panel. Therefore, a groove 1021 is set in the second area 102 between the cutting line 8 and the first area 101, and a blocking structure 2 is filled in the groove 1021. The blocking structure 2 can disconnect the first inorganic film layer 12 at the position of the groove 1021, thereby preventing the cracks from extending along the first inorganic film layer 12 into the first area 101.

[0043] In this embodiment, a groove 1021 is provided in the second region 102 around the outer periphery of the first region 101, and the first inorganic film layer 12 and a part of the substrate 11 in the first part and the second part are disconnected at the position of the blocking structure 2 by the groove 1021, so that cracks in the second region 102 cannot extend along the first inorganic film layer 12 into the first region 101, thereby enhancing the stability of the display panel, making it more reliable during use, and further extending the service life of the display panel. Preventing the extension of cracks can improve the display effect of the display panel, enhance the user's visual experience, and further enhance the user experience of the operator.

[0044] In the related art, refer to Figure 8 and Fig. 9 , the first inorganic film layer 12 at the edge of the display panel is completely etched to produce a groove that penetrates the first inorganic film layer 12, and the bottom of the groove is located between the first inorganic film layer 12 and the substrate 11, so as to avoid the problem of crack extension caused by the residue of the first inorganic film layer 12. However, this setting method is not easy to control the etching depth of the first inorganic film layer 12. With the fluctuation of the process, there will still be the problem of the residue of the first inorganic film layer 12, which will cause the following problems: Fig.10 and Fig.11The situation shown in the figure occurs, the first inorganic film layer 12 is not completely etched, and a part of the first inorganic film layer 12 that has not been etched remains on the side close to the substrate 11, resulting in that when the display panel is cut, cracks in the first inorganic film layer 12 extend along the unetched part to the interior of the display panel, thereby causing the screen to fail and affecting the screen display. The groove 1021 passes through each first inorganic film layer 12 and the bottom of the groove 1021 is located in the substrate 11. The first inorganic film layer 12 and part of the substrate 11 in the first part and the second part are disconnected at the position of the blocking structure 2 through the groove 1021, so that the cracks in the second area 102 cannot extend along the first inorganic film layer 12 to the first area 101, thereby enhancing the stability of the display panel and making it more reliable during use, thereby extending the service life of the display panel. Preventing the extension of the cracks can improve the display effect of the display panel, enhance the user's visual experience, and thus enhance the operator's experience. At the same time, the etching of the groove 1021 can be completed in combination with the etching process in the existing array process, which can simplify the manufacturing process and save manufacturing time and production costs.

[0045] In one embodiment, a plurality of grooves 1021 are provided, and the plurality of grooves 1021 are arranged at intervals in a direction away from the edge of the first region 101. Figure 2 The number of the grooves 1021 is 3. With this design, the first inorganic film layer 12 and part of the substrate 11 are disconnected at the position of the grooves 1021, so that the cracks in the second region 102 cannot extend along the first inorganic film layer 12 into the first region 101. When the grooves 1021 are set, they can be formed by etching in the UC process in the array process, which reduces the production process and reduces the production cost.

[0046] In one embodiment, referring to Figure 1 and Figure 2 , the width of each groove 1021 is the same. With this design, when there are multiple grooves 1021, the width of each groove 1021 is equal, which facilitates the design of the layout, improves the development efficiency, and saves development time and production costs. The longitudinal cross-section shape of the groove 1021 can be a rectangle, an ellipse, an inverted trapezoid, etc. For example Figure 2The longitudinal cross-sectional shape of the groove 1021 shown is an inverted trapezoid, and no specific limitation is made in this embodiment, as long as the first inorganic film layer 12 can be separated by the groove 1021. The bottom of the groove 1021 is set in the substrate 11, and the top opening of the groove 1021 is set on the side of the first inorganic film layer 12 away from the substrate 11, wherein the top of the groove 1021 has the maximum width relative to the bottom of the groove, and the width of the groove 1021 gradually decreases from the top to the bottom of the groove. Such a design can not only increase the stress dispersion effect around the groove 1021 and prevent cracks caused by stress concentration, but also can well disconnect the first inorganic film layer 12 at the position of the groove 1021, thereby preventing the cracks caused by cutting from extending into the first region 101.

[0047] In another embodiment, referring to Figure 3 and Figure 4 , along the direction away from the edge of the first region 101, the width of the groove 1021 decreases successively, that is, referring to Figure 4 , the end of the groove 1021 away from the first region 101 has the smallest width, that is, the side close to the cutting line 8 has the smallest width, and the width of the groove 1021 gradually increases along the direction close to the first region 101, so that the first inorganic film layer 12 can be disconnected at the position of the groove 1021, thereby preventing the cracks generated by the cutting from extending into the first region 101. The wider groove 1021 can ensure the filling of the blocking structure 2, and the width of the groove 1021 close to the first region 101 is designed to be wider, which can effectively avoid stress concentration caused by incomplete filling of the blocking structure 2.

[0048] In one embodiment, referring to Figure 1 and Figure 2 , the depth of each groove 1021 is the same. With such a design, when a plurality of grooves 1021 are provided, the grooves 1021 are etched. Since the depth of each groove 1021 is equal, it is easier to control the etching process, thereby avoiding the situation where some grooves 1021 are over-etched while other grooves 1021 are under-etched, simplifying the manufacturing process, thereby saving manufacturing time and production costs. The longitudinal cross-section shape of the groove 1021 can be a rectangle, an ellipse, an inverted trapezoid, etc. For example Figure 2The longitudinal cross-sectional shape of the groove 1021 shown is an inverted trapezoid, and no specific limitation is made in this embodiment, as long as the first inorganic film layer 12 can be separated by the groove 1021. The bottom of the groove 1021 is set in the substrate 11, and the top opening of the groove 1021 is set on the side of the first inorganic film layer 12 away from the substrate 11, wherein the top of the groove 1021 has the maximum width relative to the bottom of the groove, and the width of the groove 1021 gradually decreases from the top to the bottom of the groove. Such a design can not only increase the stress dispersion effect around the groove 1021 and prevent cracks caused by stress concentration, but also can well disconnect the first inorganic film layer 12 at the position of the groove 1021, thereby preventing the cracks caused by cutting from extending into the first region 101.

[0049] In another embodiment, referring to Figure 3 and Figure 4 , the depth of the groove 1021 decreases in sequence along the direction away from the edge of the first region 101, that is, referring to Figure 4 The depth of the groove 1021 at the end away from the first region 101 is the shallowest, that is, the depth of the groove 1021 on the side close to the cutting line 8 is the shallowest, and along the direction close to the first region 101, the depth of the groove 1021 gradually increases, which can form a multi-level partition for the first inorganic film layer 12 of the first region, further preventing the cracks generated by cutting from extending into the first region 101.

[0050] In one embodiment, the blocking structure 2 is an organic material, wherein a groove 1021 is provided on the first inorganic film layer 12 and the substrate 11. Due to the sudden change in the geometric shape of the edge of the groove 1021, the stress distribution at the edge of the groove 1021 will change, the stress in the local area will increase significantly, and stress concentration will occur. Therefore, the organic colloid used in making the touch layer 5 can be used to fill the groove 1021, and no specific limitation is made in this embodiment. Such a design can prevent the array substrate 1 from stress concentration at the position of the groove 1021, and further prevent fatigue cracks in the first inorganic film layer 12 caused by stress concentration, thereby effectively preventing the cracks from extending along the first inorganic film layer 12 into the first area 101, thereby enhancing the stability of the display panel.

[0051] In one embodiment, the blocking structure 2 includes a connected covering portion 21 and a filling portion 22, wherein the covering portion 21 covers the outer surface of the outermost first inorganic film layer 12, and the filling portion 22 fills the groove 1021. Figure 2 , Figure 4 and Figure 6The blocking structure 2 includes a connected covering portion 21 and a filling portion 22. The covering portion 21 and the filling portion 22 may be an integral structure or a separate structure assembled in a piece by adhesion or the like. The filling portion 22 is adapted to the shape of the groove 1021 and may be changed according to the change of the shape of the groove 1021. The covering portion 21 is arranged on the side of the outermost first inorganic film layer 12 away from the substrate 11. The structural stability may be increased by placing the covering portion 21. The covering portion 21 may provide additional support and protection to prevent the first inorganic film layer 12 from being damaged by external stress.

[0052] In one embodiment, the array substrate 1 further includes a plurality of conductive layers 13 disposed on the substrate 11 and located in the first region 101, at least one first inorganic film layer 12 is disposed between adjacent conductive layers 13, each first inorganic film layer 12 extends to the second region 102 and is stacked in the second region 102, and the groove 1021 penetrates each first inorganic film layer 12. For example, referring to Figure 1 , a multi-layer conductive layer 13 is provided on the side of the first inorganic film layer 12 away from the substrate 11, and the multi-layer conductive layer 13 is used to form a circuit structure such as a driving circuit and a signal line in the array substrate 1. At least one first inorganic film layer 12 is provided between adjacent conductive layers 13. With such a design, the first inorganic film layer 12 can be used as a protective layer, and the first inorganic film layer 12 can prevent the conductive layer 13 from being affected by the external environment, such as dust, moisture, etc., thereby improving the stability and reliability of the display panel. At the same time, each first inorganic film layer 12 extends to the second area 102 and is stacked in the second area 102, that is, in Figure 2 In the embodiment, the first inorganic film layer 12 is stacked in the area between the cutting line 8 and the conductive layer 13, and a groove 1021 is set in the stacked area to penetrate each first inorganic film layer 12. With this design, the first inorganic film layer 12 is disconnected at the position of the groove 1021, so that the cracks in the second area 102 cannot extend along the first inorganic film layer 12 to the first area 101, thereby enhancing the stability of the display panel.

[0053] In one embodiment, referring to 2 and Figure 4 , the substrate 11 includes a first substrate 111, a second inorganic film layer 112, and a second substrate 113 which are stacked, and the bottom of the groove 1021 is located in the second substrate 113. For example, referring to Figure 2A second substrate 113 is disposed on a side close to the first inorganic film layer 12, a second inorganic film layer 112 is disposed below the second substrate 113, and a first substrate 111 is disposed below the second inorganic film layer 112. In order to better realize the flexible and bendable functions of the display panel, the first substrate 111 and the second substrate 113 can be made of high-performance polymer materials such as polyimide substrates, and the first inorganic film layer 12 and the second inorganic film layer 112 can be made of inorganic materials such as silicon nitride, silicon oxide, and silicon oxynitride. In this regard, the first substrate 111, the second substrate 113, and the first inorganic film layer 12 and the second inorganic film layer 112 are made of inorganic materials such as silicon nitride, silicon oxide, and silicon oxynitride. The materials of the first inorganic film layer 12 and the second inorganic film layer 112 are not limited. In the present embodiment, the first substrate 111 and the second substrate 113 are both polyimide substrates. The above is only an exemplary description. The first substrate 111 and the second substrate 113 can also be made of other organic materials. It can be understood that the first substrate 111 and the second substrate 113 can be made of the same organic material or different organic materials, and the first inorganic film layer 12 and the second inorganic film layer 112 can be made of the same inorganic material or different inorganic materials. Among them, the bottom of the groove 1021 is located in the second substrate 113. With such a design, the first inorganic film layer 12 can be disconnected at the position of the groove 1021, so that the cracks in the second region 102 cannot extend along the first inorganic film layer 12 into the first region 101, thereby enhancing the stability of the display panel.

[0054] In another embodiment, referring to Figure 5 and Figure 6 The substrate 11 includes a first substrate 111, a second inorganic film layer 112, and a second substrate 113 that are stacked, the groove 1021 penetrates the second substrate 113 and the second inorganic film layer 112, and the bottom of the groove 1021 is located in the first substrate 111. For example, referring to Figure 5 A second substrate 113 is arranged on a side close to the first inorganic film layer 12, a second inorganic film layer 112 is arranged below the second substrate 113, and a first substrate 111 is arranged below the second inorganic film layer 112, wherein the first substrate 111 and the second substrate 113 can be made of flexible organic materials such as polyimide substrates, and the first inorganic film layer 12 and the second inorganic film layer 112 can be made of inorganic materials with high hardness and strength. It can be understood that inorganic materials have good water and oxygen resistance, hardness and strength, and can withstand large external stress, while organic materials have certain softness and processability, and can meet the needs of flexible display panels. In the manufacturing process of the array substrate 1, the alternating arrangement of inorganic materials and organic materials can give full play to their respective advantages and improve the overall performance of the array substrate 1.

[0055] Among them, refer to Figure 6The groove 1021 passes through the first inorganic film layer 12, the second substrate 113 and the second inorganic film layer 112, and the bottom of the groove 1021 is located in the first substrate 111. With this design, not only the first inorganic film layer 12 can be disconnected at the position of the groove 1021, but also the second inorganic film layer 112 can be disconnected at the position of the groove 1021, so that cracks on each layer of the inorganic film layer in the second area 102 cannot extend into the first area 101, thereby enhancing the stability of the display panel.

[0056] In one embodiment, the display panel further includes a light-emitting layer 3 and an encapsulation layer 4. The light-emitting layer 3 is disposed on the array substrate 1; the encapsulation layer 4 is disposed on the light-emitting layer 3, and the encapsulation layer 4 includes a third inorganic film layer 41, a first organic film layer 42, and a fourth inorganic film layer 43 that are stacked, and the encapsulation layer 4 is located in the first area 101. For example, referring to Figure 1 and Figure 2 , a light-emitting layer 3 is provided on the side of the first inorganic film layer 12 away from the substrate 11. The light-emitting layer 3 is the core part of the display panel and is responsible for converting electrical signals into optical signals to display images or texts. The encapsulation layer 4 is covered on the light-emitting layer 3. The encapsulation layer 4 can improve the safety of the display panel and prevent the external environment from damaging the internal functional layers. For example, the encapsulation layer 4 can prevent external moisture, dust, etc. from entering the interior of the display panel, thereby extending the service life of the display panel. Among them, the encapsulation layer 4 includes a third inorganic film layer 41, a first organic film layer 42 and a fourth inorganic film layer 43. The third inorganic film layer 41 and the fourth inorganic film layer 43 are wrapped inside the first organic film layer 42. At least one dam is also provided between the encapsulation layer 4 and the groove 1021. In this embodiment, two dams are provided. Of course, one or more dams can be provided in its embodiment, and at least one dam is provided around the edge of the encapsulation layer 4.

[0057] For example, refer to Figure 1 A first dam 6 is provided on the left side of the encapsulation layer 4. The first dam 6 surrounds the edge of the encapsulation layer 4. A second dam 7 is provided on the left side of the first dam 6. The third inorganic film layer 41 extends and covers the first dam 6 and the second dam 7, and ends before the groove 1021, that is, Figure 1 The left side of the middle groove 1021. The material of the first organic film layer 42 in the encapsulation layer 4 has fluidity, so the first dam 6 and the second dam 7 can be used to define the edge of the first organic film layer 42 to prevent the material in the first organic film layer 42 from overflowing, and to prevent the first organic film layer 42 from communicating with the outside, causing external water vapor, oxygen, etc. to enter the interior of the display panel through the first organic film layer 42, thereby ensuring the encapsulation effect.

[0058] In one embodiment, the display panel further includes a touch layer 5, the touch layer 5 is disposed on the encapsulation layer 4, the touch layer 5 includes a second organic film layer, and the second organic film layer and the barrier structure 2 are disposed in the same layer. Figure 1 , a touch layer 5 is provided on the side of the encapsulation layer 4 away from the array substrate 1, and the touch layer 5 is used to realize the touch function. Among them, when the groove 1021 is filled with organic colloid, the organic colloid used in making the touch layer 5 can be used for filling, and no specific limitation is made in this embodiment.
