Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] In existing OLED products, the distance between the display area outside the encapsulation area and the cut edge of the hole area is very short. When there is electric field concentration in the hole area, this concentration can cause static electricity to be conducted to the encapsulation area and then to the display area. This can affect the driving circuit in the display screen, causing characteristic shifts and affecting the normal display of the OLED screen. Summary of the Invention

[0003] Therefore, it is necessary to provide a display panel and display device that can conduct away static electricity, reduce static electricity accumulation, block static electricity from being conducted to the display area, and ensure normal display of the screen.

[0004] In a first aspect, embodiments of this application provide a display panel. The display panel includes a perforated area and a first non-display area; the first non-display area is disposed on the outer periphery of the perforated area; the display panel includes an insulating layer and a conductive element. The insulating layer includes a first surface and a second surface that are disposed opposite to and spaced apart along the thickness direction of the insulating layer. The insulating layer has a through-hole that penetrates the insulating layer along its thickness direction. The orthographic projection of the through-hole onto the plane of the first surface coincides with the orthographic projection of the perforated area onto the plane of the first surface. The insulating layer has an annular groove, the opening of which is located on the first surface. The annular groove is located in the first non-display area and is disposed on the outer periphery of the perforated area. The conductive element is disposed on the side of the first surface away from the second surface. The conductive element is located in the first non-display area and is arranged around the outer periphery of the perforated area. The orthographic projection of the conductive element onto the plane of the first surface and the orthographic projection of the opening of the annular groove onto the plane of the first surface are arranged along the direction from the perforated area to the first non-display area.

[0005] The display panel provided in this application embodiment includes an insulating layer and a conductive element. The insulating layer includes a first surface and a second surface that are opposite to and spaced apart along the thickness direction of the insulating layer. The insulating layer has through-holes that penetrate the insulating layer along its thickness direction. The orthographic projection of the through-holes onto the plane of the first surface coincides with the orthographic projection of the perforated area onto the plane of the first surface. The insulating layer also has an annular groove, the opening of which is located on the first surface. The annular groove is located in a first non-display area and is disposed around the outer periphery of the perforated area. The conductive element is disposed on the side of the first surface away from the second surface. The conductive element is located in the first non-display area and is arranged around the outer periphery of the perforated area. The orthographic projection of the conductive element onto the plane of the first surface and the orthographic projection of the opening of the annular groove onto the plane of the first surface are arranged along the direction from the perforated area to the first non-display area. Thus, by providing an annular groove in the insulating layer, with the opening of the groove located on the first surface and the groove located in the first non-display area and around the outer periphery of the perforated area, the area for electrostatic conduction on the first surface can be increased through the annular groove, thereby reducing the area for electrostatic conduction in other parts. Furthermore, since a conductive element is provided on the side of the first surface away from the second surface, the conductive element is located in the first non-display area and is arranged around the outer periphery of the perforated area. At the same time, the orthographic projection of the conductive element on the plane of the first surface and the orthographic projection of the groove opening of the annular groove on the plane of the first surface are arranged along the direction from the perforated area to the first non-display area.

The orthographic projection of the conductive element onto the plane of the first surface and the orthographic projection of the opening of the annular groove onto the plane of the first surface are arranged along the direction from the perforated area to the first non-display area. Thus, by providing an annular groove in the insulating layer, with the opening of the groove located on the first surface and the groove located in the first non-display area and around the outer periphery of the perforated area, the area for electrostatic conduction on the first surface can be increased through the annular groove, thereby reducing the area for electrostatic conduction in other parts. Furthermore, since a conductive element is provided on the side of the first surface away from the second surface, the conductive element is located in the first non-display area and is arranged around the outer periphery of the perforated area.

Detailed Implementation

[0059] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0060] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, this does not indicate any order, quantity, or importance, but is merely used to distinguish different components. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. Words such as “comprising” or “including” mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0062] Currently, in existing OLED products, the distance between the display area outside the encapsulation area and the cut edge of the hole area is very short. When there is electric field concentration in the hole area, this concentration can cause static electricity to be conducted to the encapsulation area and then to the display area. This can affect the driving circuit in the display screen, causing characteristic shifts and affecting the normal display of the OLED screen.

[0063] Based on the above research, the applicant discovered that to conduct static electricity away, structures such as metal or conductive components are required to remove static electricity present in specific areas. However, in some related technologies, the encapsulation area around the hole area of ​​some display panels does not have any metal or conductive components, which leads to the generation of a large amount of static electricity in the hole area and encapsulation area, posing risks and hidden dangers to the use of the display screen.

[0064] The applicant's further research revealed that some display panel designs take into account the impact of static electricity, incorporating metal or conductive components in specific areas to discharge static electricity. However, the applicant also discovered that while these technologies utilize metal or conductive components for static discharge, the compact design of the display panel limits the size of these components. They must be placed in areas with the greatest impact on the display area, prioritizing the conduction of static electricity closer to them, while being less effective at discharging static electricity farther away. If a large amount of static electricity is generated at a distance from the conductive component, it becomes difficult for the component to discharge it quickly enough, resulting in poor static discharge and ultimately affecting the normal display.

[0065] Firstly, referring to Figure 1 , Figure 2 and Figure 3As shown, this application embodiment provides a display panel 10. The display panel 10 includes a perforated area 10a and a first non-display area 10b; the first non-display area 10b is disposed on the outer periphery of the perforated area 10a; the display panel 10 includes an insulating layer 1 and a conductive element 2. The insulating layer 1 includes a first surface 1a and a second surface 1b that are disposed opposite to and spaced apart along the thickness direction of the insulating layer 1. The insulating layer 1 is provided with a through hole 1c, which penetrates the insulating layer 1 along the thickness direction of the insulating layer 1. The orthographic projection of the through hole 1c on the plane where the first surface 1a is located coincides with the orthographic projection of the perforated area 10a on the plane where the first surface 1a is located; the insulating layer 1 is provided with an annular groove 11, the opening of which is located on the first surface 1a; the annular groove 11 is located in the first non-display area 10b and is disposed on the outer periphery of the perforated area 10a. The conductive element 2 is disposed on the side of the first surface 1a away from the second surface 1b. The conductive element 2 is located in the first non-display area 10b and is arranged around the outer periphery of the perforated area 10a. The orthographic projection of the conductive element 2 on the plane of the first surface 1a and the orthographic projection of the groove of the annular groove 11 on the plane of the first surface 1a are arranged along the direction from the perforated area 10a to the first non-display area 10b.

[0066] The display panel 10 provided in this embodiment includes an insulating layer 1 and a conductive element 2. The insulating layer 1 includes a first surface 1a and a second surface 1b that are disposed opposite to and spaced apart along the thickness direction of the insulating layer 1. The insulating layer 1 is provided with a through hole 1c that penetrates the insulating layer 1 along the thickness direction of the insulating layer 1. The orthographic projection of the through hole 1c on the plane of the first surface 1a coincides with the orthographic projection of the perforated area 10a on the plane of the first surface 1a. The insulating layer 1 is provided with an annular groove 11, the opening of which is located on the first surface 1a. The annular groove 11 is located in the first non-display area 10b and is disposed on the outer periphery of the perforated area 10a. The conductive element 2 is disposed on the side of the first surface 1a away from the second surface 1b. The conductive element 2 is located in the first non-display area 10b and is arranged around the outer periphery of the perforated area 10a. The orthographic projection of the conductive element 2 on the plane of the first surface 1a and the orthographic projection of the opening of the annular groove 11 on the plane of the first surface 1a are arranged along the direction from the perforated area 10a to the first non-display area 10b. Thus, an annular groove 11 is provided in the insulating layer 1, with the opening of the annular groove 11 located on the first surface 1a. The annular groove 11 is located in the first non-display area 10b and is disposed on the outer periphery of the perforated area 10a. Therefore, during the electrostatic conduction process, the annular groove 11 can increase the area for electrostatic conduction on the first surface 1a, thereby reducing the area for electrostatic conduction in other parts. Furthermore, since a conductive element 2 is provided on the side of the first surface 1a away from the second surface 1b, the conductive element 2 is located in the first non-display area 10b and is arranged around the outer periphery of the perforated area 10a. At the same time, the orthographic projection of the conductive element 2 on the plane of the first surface 1a and the orthographic projection of the opening of the annular groove 11 on the plane of the first surface 1a are arranged along the direction from the perforated area 10a to the first non-display area 10b. Therefore, the conductive element 2 can conduct away the electrostatic charge conducted to the first surface 1a, thereby reducing the accumulation of electrostatic charge and blocking the conduction of electrostatic charge to the display area 10c of the display panel 10, ensuring the normal display of the display panel 10.

[0067] The through-hole 1c penetrates the insulating layer 1 along its thickness direction. The orthographic projection of the through-hole 1c onto the plane of the first surface 1a coincides with the orthographic projection of the perforated area 10a onto the plane of the first surface 1a. Therefore, the through-hole 1c forms the perforated area 10a of the display panel 10. It should be noted that the display panel 10 also includes a display area 10c, which is located on the side of the first non-display area 10b opposite to the perforated area 10a. That is, the outer periphery of the through-hole 1c is sequentially formed by the first non-display area 10b and the display area 10c.

[0068] Specifically, the punch-hole area 10a provides mounting positions for components such as cameras and sensors to enable functions such as image capture, facial recognition, and light sensing. This design allows for efficient use of space to integrate other important hardware components while ensuring that most of the display panel 10 is used for display, thereby improving the overall compactness and functionality of the device. The first non-display area 10b is located on the outer periphery of the punch-hole area 10a and is typically used to house display-related circuitry, such as drive circuits and signal lines. These circuits control the operation of each pixel in the display area 10c, transmitting signals to the display area 10c to achieve correct image display. The display area 10c is the core functional area of ​​the display panel 10, displaying various images, text, videos, and other content through numerous pixels. The pixels in the display area 10c operate according to a specific arrangement and driving method, controlling the color and brightness of each pixel based on the input electrical signals, thus combining to form a complete visual image seen by the user, providing an interface for information display and visual interaction.

[0069] It should be noted that electrostatic discharge mainly occurs in the following scenarios: static electricity from tearing the film surface, static electricity generated by personnel contact during sample transfer, static electricity generated during equipment contact, and static electricity generated by electrostatic discharge in the pore area during electrostatic discharge testing.

[0070] Based on the above explanation, during the processing and production process, when static electricity is generated in the hole area 10a or other locations, when the static electricity is conducted to the conductive component 2, the static electricity can be conducted away by the conductive component 2, thereby reducing the accumulation of static electricity and blocking the conduction of static electricity to the display area 10c of the display panel 10, ensuring the normal display of the display panel 10.

[0071] It should be further explained that if static electricity is not discharged, it will be conducted to the display area 10c, causing an increase in local current or voltage. This results in the edges of the display area 10c being brighter than the display area itself, leading to display abnormalities. Furthermore, when the amount of static charge exceeds a certain level, it can damage the display panel 10, causing black spots to appear on the display panel 10. Since the static electricity can be conducted away by the conductive component 2, reducing static accumulation, the problem of the edges of the display area 10c being brighter than the display area itself, or even developing black spots, due to static electricity can be solved.

[0072] Furthermore, since an annular groove 11 is provided in the insulating layer 1, and the opening of the annular groove 11 is located on the first surface 1a; the annular groove 11 is located in the first non-display area 10b and is located on the outer periphery of the perforated area 10a, the annular groove 11 can increase the area of ​​static electricity conduction on the first surface 1a during the static electricity conduction process, thereby reducing the area of ​​static electricity conduction in other parts. That is, during the processing and production process, when a large amount of static electricity is generated, the annular groove 11 can increase the area of ​​static electricity conduction on the first surface 1a, thereby allowing a large amount of static electricity to be conducted to the location of the annular groove 11 during the conduction process. Moreover, the increased area of ​​the annular groove 11 can reduce the speed of static electricity conduction, thereby allowing the conductive component 2 sufficient time to discharge a large amount of static electricity, thereby improving the static electricity discharge effect and ensuring the normal use of the display panel 10.

[0073] In other words, the annular groove 11 increases the area for static electricity conduction on the first surface 1a, which means extending and widening the conduction path of static electricity. When a large amount of static electricity is generated, more static electricity will be guided to the location of the annular groove 11. The longer and more encircling path provides more space for static electricity distribution during conduction, avoiding the concentration of static electricity in certain local areas, reducing the static electricity conduction area in other parts, and reducing the risk of problems caused by static electricity accumulation in these parts.

[0074] In addition, an annular groove 11 is provided in the insulating layer 1, positioned in the first non-display area 10b and surrounding the periphery of the perforated area 10a, providing a dedicated channel for electrostatic conduction. The opening of the annular groove 11 is located on the first surface 1a, allowing static electricity to easily enter the annular groove 11. Furthermore, this annular structure can uniformly surround the perforated area 10a, protecting it and preventing static electricity from affecting the display area 10c, thereby improving the display effect of the display panel 10.

[0075] Furthermore, since the annular groove 11 is located in the first non-display area 10b and on the outer periphery of the perforated area 10a, it facilitates the fabrication process of the conductive element 2. For example, when fabricating the conductive element 2 using processes such as photomasks and exposure machines, or performing photolithography, the annular groove 11 can serve a positioning or isolation function, helping to precisely control the formation of structures such as the conductive element 2. This ensures that the conductive element 2 is fabricated in a specific area. That is, because the conductive element 2 is positioned or isolated by the annular groove 11 during fabrication, it remains stable and will not encroach on the space of the perforated area 10a or the first non-display area 10b due to uncertainties or movement in its position. It also prevents the size of the first non-display area 10b from increasing during the fabrication of the conductive element 2, thus ensuring the stability and reliability of the display panel 10 fabrication process. Simultaneously, no additional process requirements are needed during the fabrication of the conductive element 2, thus facilitating the fabrication process for operators.

[0076] In one embodiment, see [reference] Figure 2 As shown, the number of annular grooves 11 is at least one, and the orthographic projection of the perforated area 10a on the plane where the first surface 1a is located is the first orthographic projection; at least one annular groove 11 includes a first annular groove 111, the orthographic projection of the conductive element 2 on the plane where the first surface 1a is located, and the side of the groove opening of the first annular groove 111 that is orthographically projected on the plane where the first surface 1a is located toward the first orthographic projection.

[0077] Thus, the number of annular grooves 11 is at least one, and at least one annular groove 11 includes a first annular groove 111. The orthographic projection of the conductive element 2 on the plane of the first surface 1a, and the side of the groove opening of the first annular groove 111 facing the orthographic projection of the first surface 1a, can form a multi-layered and more comprehensive electrostatic protection area around the periphery of the perforated area 10a. Multiple annular grooves 11 can play a role in guiding and dispersing static electricity multiple times, preventing static electricity from concentrating in a certain area. The design of the conductive element 2 located on a specific side of the first annular groove 111 allows the conductive element 2 to more effectively receive the static electricity conducted from the annular groove 11, and then conduct the static electricity in a timely manner, enhancing the overall electrostatic protection capability of the display panel 10. This can reduce static electricity accumulation, block the conduction of static electricity to the display area 10c of the display panel 10, and prevent static electricity from affecting the electrical properties of the drive circuit and other structures in the display panel 10, thus ensuring the normal display of the display panel 10.

[0078] In one embodiment, see [reference] Figure 4As shown, the number of annular grooves 11 is at least one, and the orthographic projection of the perforated area 10a on the plane where the first surface 1a is located is the first orthographic projection; at least one annular groove 11 includes a second annular groove 112, the orthographic projection of the conductive element 2 on the plane where the first surface 1a is located, and the side of the groove opening of the second annular groove 112 on the plane where the first surface 1a is located away from the first orthographic projection.

[0079] Thus, by placing the conductive element 2 on the side where the orthographic projection of the opening of the second annular groove 112 on the plane of the first surface 1a is opposite to the orthographic projection of the perforated area 10a, static electricity can be guided to diffuse and buffer first through the second annular groove 112. When static electricity is generated in the display panel 10, the static electricity will preferentially be conducted to the second annular groove 112. The increased conductive area of ​​the annular groove 112 makes the static electricity distribution more uniform. Then, the conductive element 2 located on the side opposite to the perforated area 10a will conduct the static electricity. This can prolong the path and time for the static electricity to be conducted to the conductive element 2, thereby allowing the conductive element 2 sufficient time to conduct a large amount of static electricity, thus improving the static electricity discharge effect and ensuring the normal use of the display panel 10.

[0080] In one embodiment, see [reference] Figure 5 and Figure 6 As shown, there are multiple annular grooves 11; multiple annular grooves 11 are nested sequentially from the inside to the outside, and adjacent annular grooves 11 are spaced apart; the orthographic projection of the conductive element 2 on the plane where the first surface 1a is located is between the orthographic projections of the openings of two adjacent annular grooves 11 on the plane where the first surface 1a is located.

[0081] Thus, the multiple annular grooves 11 form a multi-layered electrostatic discharge structure. When static electricity is generated, the multiple annular grooves 11 from the inside out can sequentially guide and buffer the static electricity. During the conduction of static electricity from the inner annular groove 11 to the outer annular groove 11, the increased conduction area of ​​the multiple annular grooves 11 enables more complete diffusion and uniform distribution, reducing the concentration of static electricity and minimizing damage to the display panel 10. This further reduces static electricity accumulation and better blocks the conduction of static electricity to the display area 10c of the display panel 10, ensuring the normal display of the display panel 10.

[0082] Furthermore, the structure of multiple annular grooves 11 enhances the structural strength around the perforated area 10a. The spacing between adjacent annular grooves 11 ensures that each annular groove 11 plays an independent role in electrostatic discharge and also disperses the stress around the perforated area 10a to a certain extent. The conductive element 2 is located between adjacent annular grooves 11, further strengthening the structural stability of this area. This makes the area around the perforated area 10a less prone to deformation and cracking when the display panel 10 is subjected to external forces or temperature changes, thus improving the reliability and durability of the display panel 10.

[0083] In one embodiment, see [reference] Figure 7 As shown, the conductive element 2 includes a plurality of sub-conductive parts 21, which are arranged at intervals along the circumferential direction of the perforated area 10a.

[0084] It should be noted that the static electricity distribution around the perforated area 10a may not be uniform. Therefore, multiple sub-conductive parts 21 are arranged at intervals along the circumference, which can more comprehensively and evenly conduct away static electricity generated at different locations around the perforated area 10a. No matter where the static electricity appears around the perforated area 10a, the corresponding sub-conductive part 21 can promptly conduct it away, avoiding the accumulation of static electricity due to insufficient local collection and improving the efficiency and effectiveness of static electricity collection.

[0085] In one embodiment, the conductive element 2 is annular in shape and is configured as a conductive ring, which is disposed around the outer periphery of the perforated area 10a.

[0086] In this way, the annular conductive element 2 can surround the perforated area 10a, forming a continuous electrostatic conduction structure. This maximizes contact with the static electricity generated around the perforated area 10a, efficiently conducts the static electricity, and conducts it evenly along the annular path of the conductive ring, avoiding the accumulation of static electricity in local areas. This further improves the static electricity discharge effect of the conductive element 2, better reduces static electricity accumulation, and better blocks the conduction of static electricity to the display area 10c of the display panel 10, further reducing the impact on the driving circuit and other structures in the display panel 10, and improving the display effect of the display panel 10.

[0087] In one embodiment, the insulating layer 1 is configured as a substrate.

[0088] Thus, since the insulating layer 1 is constructed as a substrate, the substrate effectively prevents current leakage and short circuits between different components or lines, ensuring that the current flows along the designed path and guaranteeing the normal operation and safety of the circuit. For example, in the display panel 10, current crosstalk between pixel electrodes can be prevented, allowing each pixel to independently control and display color. Simultaneously, the substrate provides mechanical support for other functional layers or components, maintaining their position and shape. Other film layers can be supported in the display panel 10, keeping the entire display structure stable and less susceptible to damage during production, transportation, and use.

[0089] In one embodiment, the display panel 10 further includes a display area 10c, which is disposed on the side of the first non-display area 10b opposite to the cutout area 10a.

[0090] In this way, the display area 10c is separated from the punch-hole area 10a, avoiding visual interference from the punch-hole area 10a to the display area 10c. The punch-hole area 10a is usually used to place components such as cameras, which can compromise the integrity of the display panel 10 to some extent. If the display area 10c is adjacent to the punch-hole area 10a, it may cause problems such as distortion and uneven color of the display content around the punch-hole area 10a, affecting the visual experience. By placing the display area 10c on the side of the first non-display area 10b away from the punch-hole area 10a, the image displayed in the display area 10c can be more complete and smooth, with more uniform color and brightness, providing users with a better visual experience.

[0091] In one embodiment, the display panel 10 further includes a second non-display area 10d, which is disposed on the outer periphery of at least a portion of the display area 10c.

[0092] Therefore, the display panel 10 needs to possess a certain level of mechanical strength and stability during use. The second non-display area 10d can serve as a frame or support structure for the display area 10c, providing mechanical protection and support for the display area 10c. This allows it to withstand external pressure and impact, preventing damage to the display area 10c. It also helps maintain the overall shape and structural stability of the display panel 10, playing a role in fixing and protecting the display area 10c during installation and use.

[0093] In one embodiment, see [reference] Figure 8 As shown, along the direction from the perforated area 10a to the first non-display area 10b, the annular groove 11 includes a first groove sidewall 11a and a second groove sidewall 11b that are opposite to and spaced apart; along the direction from the first surface 1a to the second surface 1b, the size between at least a portion of the first groove sidewall 11a and at least a portion of the second groove sidewall 11b gradually increases.

[0094] Thus, along the direction from the first surface 1a to the second surface 1b, the dimensions between the first groove sidewall 11a and the second groove sidewall 11b gradually increase, forming a groove structure similar to a trapezoid or cone. This gradually changing structure of the first groove sidewall 11a and the second groove sidewall 11b can better disperse stress. When an external force is applied to the display panel 10 itself, the gradually increasing dimensions of the first groove sidewall 11a and the second groove sidewall 11b can make the stress more evenly distributed on the first groove sidewall 11a and the second groove sidewall 11b, avoiding stress concentration in a certain part, thereby enhancing the stability and reliability of the entire structure and reducing the probability of cracking, deformation, and other problems caused by stress concentration.

[0095] Furthermore, since the annular groove 11 includes a first groove sidewall 11a and a second groove sidewall 11b that are opposite to and spaced apart along the direction from the perforated area 10a to the first non-display area 10b; along the direction from the first surface 1a to the second surface 1b, the size between at least a portion of the first groove sidewall 11a and at least a portion of the second groove sidewall 11b gradually increases, that is, the annular groove 11 is formed as an "undercut structure" or a "partition structure", thereby separating different areas, preventing accidental conduction of current between the perforated area 10a and the display area 10c, avoiding interference between circuits, and ensuring the normal operation and electrical stability of the display panel 10.

[0096] In one embodiment, see [reference] Figure 9 As shown, the annular groove 11 also includes a groove bottom wall 11c, which is connected to the first groove side wall 11a and the second groove side wall 11b. At least one of the first groove side wall 11a, the groove bottom wall 11c, and the second groove side wall 11b is an arc-shaped wall, which protrudes in a direction away from the center of the annular groove 11.

[0097] Thus, when the display panel 10 is in operation or subjected to external forces, the curved wall can evenly distribute the stress it bears throughout the entire structure. Compared to the right-angled or straight first slot sidewall 11a and second slot sidewall 11b, the curved wall has no sharp corners, and the stress will not concentrate at a specific point, thereby reducing the risk of structural damage or breakage due to stress concentration and improving the reliability and durability of the display panel 10.

[0098] Meanwhile, the curved wall can serve as part of the partition structure, and its curved shape can more effectively block or guide the transmission of matter, energy or signals, thus making it easier for the annular groove 11 to be formed as an "undercut structure" or "partition structure".

[0099] In one embodiment, the annular groove 11 further includes a groove bottom wall 11c, which is connected to the first groove side wall 11a and the second groove side wall 11b; at least one of the first groove side wall 11a and the second groove side wall 11b intersects the groove bottom wall 11c at an incline.

[0100] Thus, the inclined intersecting structure makes the overall shape of the annular groove 11 more reasonable, and can better adapt to the stress that the display panel 10 bears under different working conditions. When the display panel 10 is subjected to external pressure or tension, this inclined structure can evenly distribute the stress to each part, avoiding stress concentration at the connection between the first groove sidewall 11a and the second groove sidewall 11b and the groove bottom wall 11c, thereby enhancing the structural stability of the annular groove 11 and the entire display panel 10, and reducing problems such as cracking and deformation caused by stress concentration.

[0101] In one embodiment, see [reference] Figure 10 and Figure 11 As shown, the display panel 10 also includes a first electrode layer 3; the first electrode layer 3 includes a first electrode portion 31 and a second electrode portion 32 located in the first non-display area 10b. The first electrode portion 31 is disposed on the side of the first surface 1a away from the second surface 1b, and the second electrode portion 32 covers the bottom wall 11c of the annular groove 11; the first electrode portion 31 and the second electrode portion 32 are spaced apart.

[0102] Thus, dividing the first electrode portion 31 into two parts located at different and spaced intervals allows for partitioning at different locations. The first electrode portion 31 is located at a specific position in the first non-display area 10b. During the fabrication of the first electrode layer 3, the first electrode portion 31 and the second electrode portion 32 can be separated by the "undercut structure" of the annular groove 11. Furthermore, by placing both the first electrode portion 31 and the second electrode portion 32 in the first non-display area 10b, interference with the circuitry of the display area 10c can be avoided, ensuring the normal display of the display panel 10. Simultaneously, since both the first electrode portion 31 and the second electrode portion 32 are made of conductive material, the static electricity discharge effect can be further improved, reducing static electricity accumulation and better preventing static electricity conduction to the display area 10c of the display panel 10. This further reduces the impact on structures such as the driving circuitry in the display panel 10, improving the display effect of the display panel 10.

[0103] In one embodiment, see [reference] Figure 10 , Figure 11 and Figure 12 As shown, the first electrode part 31 includes a plurality of first sub-parts 311 arranged at intervals. The plurality of first sub-parts 311 are arranged in sequence from the inside to the outside around the outer periphery of the hole area 10a. The orthographic projection of the groove opening of the annular groove 11 on the plane where the first surface 1a is located is between the orthographic projections of adjacent first sub-parts 311 on the plane where the first surface 1a is located.

[0104] Thus, the structure of multiple first sub-sections 311 arranged in a ring increases the structural stability of the first electrode section 31. When the display panel 10 is subjected to external forces or thermal stress, this ring-shaped distribution structure can better disperse the stress, avoid stress concentration at a certain point or in a certain area, thereby reducing the risk of cracks or damage to the first electrode layer 3 and improving the reliability and service life of the display panel 10.

[0105] Meanwhile, since the first electrode portion 31 includes a plurality of first sub-portions 311 spaced apart, the effect of discharging static electricity can be further improved by the plurality of first sub-portions 311, and the accumulation of static electricity can be reduced better.

[0106] In one embodiment, the display panel 10 includes a display area 10c, which is disposed on the side of the first non-display area 10b opposite to the cutout area 10a.

[0107] In this way, the display area 10c is separated from the punch-hole area 10a, avoiding visual interference from the punch-hole area 10a to the display area 10c. The punch-hole area 10a is usually used to place components such as cameras, which can compromise the integrity of the display panel 10 to some extent. If the display area 10c is adjacent to the punch-hole area 10a, it may cause problems such as distortion and uneven color of the display content around the punch-hole area 10a, affecting the visual experience. By placing the display area 10c on the side of the first non-display area 10b away from the punch-hole area 10a, the image displayed in the display area 10c can be more complete and smooth, with more uniform color and brightness, providing users with a better visual experience.

[0108] In one embodiment, see [reference] Figure 10 , Figure 11 and Figure 12 As shown, the first electrode layer 3 includes a third electrode portion 33 located in the display area 10c. The third electrode portion 33 and the one of the plurality of first sub-parts 311 that is furthest from the hole area 10a are integrally structured.

[0109] Thus, by designing the third electrode portion 33 and the specific first sub-part 311 as an integral structure during the manufacturing process, the number of steps and process complexity in the electrode layer fabrication can be reduced. For example, in processes such as photolithography and exposure, these two parts can be patterned and processed as a whole, reducing additional process steps such as alignment and connection, which is beneficial to improving production efficiency, reducing manufacturing costs, and also helps to improve product consistency and yield.

[0110] In one embodiment, the first electrode layer 3 includes a third electrode portion 33 located in the display area 10c. The orthographic projection of the third electrode portion 33 on the plane of the first surface 1a does not overlap with the orthographic projection of the one of the plurality of first sub-parts 311 that is furthest from the hole area 10a on the plane of the first surface 1a.

[0111] Thus, in terms of manufacturing processes, this design facilitates the implementation of processes such as photolithography and etching. The non-overlapping projections provide clearer boundaries and space for pattern creation during the process, enabling more precise control over the shape and position of the first electrode layer 3, improving process controllability and precision. Simultaneously, it provides greater flexibility in the design of the display panel 10, allowing designers to independently optimize the shape, size, and position of the third electrode section 33 and the first sub-section 311 according to specific display requirements, achieving better display performance and functional integration.

[0112] In one embodiment, see [reference] Figure 11As shown, the display panel 10 also includes a second electrode layer 4, which is located within the display area 10c and does not overlap with the first non-display area 10b and the cutout area 10a; the second electrode layer 4 is disposed between the third electrode portion 33 and the insulating layer 1.

[0113] Thus, the second electrode layer 4 and the first electrode layer 3 work together to provide the necessary electric field driving conditions for the light-emitting elements in the display panel 10. When a voltage is applied, electrons start from the first electrode layer 3, pass through the light-emitting layer 5, and reach the second electrode layer 4, forming a complete current loop, thereby enabling the display panel 10 to work normally and display images.

[0114] In one embodiment, see [reference] Figure 11 As shown, the display panel 10 also includes a light-emitting layer 5, which is located in the display area 10c and does not overlap with the first non-display area 10b and the cutout area 10a; the light-emitting layer 5 is disposed between the second electrode layer 4 and the third electrode portion 33.

[0115] Thus, the light-emitting layer 5 is the core functional layer for image display in the display panel 10. When a suitable voltage is applied between the second electrode layer 4 and the first electrode layer 3, electrons are injected from the first electrode layer 3 and holes are injected from the second electrode layer 4. They meet and recombine in the light-emitting layer 5, releasing energy in the form of photons, thereby achieving light emission. By controlling the light emission intensity and color at different pixel positions, various images and screens can be combined, thus ensuring the normal display of the display panel 10.

[0116] In one embodiment, see [reference] Figure 11 As shown, the display panel 10 also includes a cover plate 6, which is disposed on the side of the first electrode layer 3 away from the insulating layer 1.

[0117] Thus, the cover plate 6 typically possesses a certain degree of hardness and strength, protecting the underlying first electrode layer 3, insulating layer 1, and other internal structures from external physical impacts, scratches, and abrasions. For example, in daily use, the cover plate 6 can prevent devices such as mobile phones from being accidentally dropped or scratched by sharp objects, thereby extending the service life of the display panel 10.

[0118] In one embodiment, see [reference] Figure 10 and Figure 11 As shown, the insulating layer 1 includes a first sub-insulating layer 12 and a second sub-insulating layer 13 stacked sequentially in the direction away from the conductive element 2; the annular groove 11 penetrates the first sub-insulating layer 12 and is recessed in the second sub-insulating layer 13.

[0119] Thus, since the annular groove 11 penetrates the first sub-insulating layer 12 and is recessed into the second sub-insulating layer 13, it can play a role in stress relief and buffering to a certain extent. Various stresses are generated during the manufacturing process of the display panel 10. The presence of the annular groove 11 can serve as a stress concentration area, alleviating some stress through its shape and structure, reducing material deformation and cracking caused by stress, improving the mechanical stability and reliability of the display panel 10, reducing the risk of performance degradation or failure caused by stress, and thereby extending the service life of the display panel 10.

[0120] In one embodiment, the insulating layer 1 further includes a third sub-insulating layer 14; the third sub-insulating layer 14 is disposed on the side of the second sub-insulating layer 13 opposite to the first sub-insulating layer 12.

[0121] Thus, since the third sub-insulating layer 14 is disposed on the side of the second sub-insulating layer 13 away from the first sub-insulating layer 12, it can provide a certain support for the upper structure, which helps to maintain the overall flatness and stability of the display panel 10.

[0122] In one embodiment, the insulating layer 1 further includes a fourth sub-insulating layer 15; the fourth sub-insulating layer 15 is disposed on the side of the third sub-insulating layer 14 opposite to the second sub-insulating layer 13.

[0123] Thus, since the fourth sub-insulating layer 15 is disposed on the side of the third sub-insulating layer 14 away from the second sub-insulating layer 13, the fourth sub-insulating layer 15 can provide a certain support for the upper structure, which helps to maintain the overall flatness and stability of the display panel 10.

[0124] In one embodiment, the third sub-insulating layer 14 is made of the same material as the first sub-insulating layer 12.

[0125] Thus, using the same material means they have similar insulation properties, such as resistivity and dielectric constant. This helps to provide a stable and consistent insulation effect throughout the entire insulation layer 1 structure, ensuring that current flows within the display panel 10 according to the designed path, reducing the risk of leakage and short circuits, thereby improving the stability and reliability of the display panel 10. At the same time, using the same material reduces the variety of raw materials and inventory management costs, while also simplifying material selection, processing, and process control during manufacturing. The production process does not require frequent switching between different material processing techniques, reducing process complexity and the probability of errors, which is beneficial for improving production efficiency and product yield.

[0126] In one embodiment, the fourth sub-insulating layer 15 is made of the same material as the second sub-insulating layer 13.

[0127] Thus, using the same material means they have similar insulation properties, such as resistivity and dielectric constant. This helps to provide a stable and consistent insulation effect throughout the entire insulation layer 1 structure, ensuring that current flows within the display panel 10 according to the designed path, reducing the risk of leakage and short circuits, thereby improving the stability and reliability of the display panel 10. At the same time, using the same material reduces the variety of raw materials and inventory management costs, while also simplifying material selection, processing, and process control during manufacturing. The production process does not require frequent switching between different material processing techniques, reducing process complexity and the probability of errors, which is beneficial for improving production efficiency and product yield.

[0128] In one embodiment, at least one of the third sub-insulating layer 14 and the first sub-insulating layer 12 is made of a different material than at least one of the fourth sub-insulating layer 15 and the second sub-insulating layer 13.

[0129] Thus, the surface characteristics of insulation layer 1 are different due to the different materials. Combining certain materials can achieve better interlayer bonding, which can ensure the stability of the multilayer insulation structure, reduce the occurrence of problems such as interlayer peeling, and thus ensure the overall stability and reliability of insulation layer 1.

[0130] In one embodiment, see [reference] Figure 11 As shown, the display panel 10 also includes a support layer 7, which is disposed on the side of the fourth sub-insulating layer 15 away from the third sub-insulating layer 14.

[0131] Thus, the display panel 10 is typically a relatively thin structure. The support layer 7 provides solid support for the entire display panel 10, enabling it to maintain a stable shape and structure, preventing deformation, bending or damage due to external forces during manufacturing, transportation, installation and use, and protecting the various internal functional layers.

[0132] In one embodiment, see [reference] Figure 11 As shown, the display panel 10 also includes a buffer layer 8, which is disposed on the side of the support layer 7 away from the fourth sub-insulating layer 15.

[0133] Thus, the display panel 10 may be subjected to external forces such as vibration and impact during use. The buffer layer 8 can effectively absorb and disperse these external forces, reduce the impact of external forces on the internal structure of the display panel 10, and avoid problems such as pixel damage, electrode breakage, and insulation layer 1 rupture caused by vibration or impact, thereby protecting the performance and stability of the display panel 10.

[0134] In one embodiment, the buffer layer 8 is provided with a plurality of connecting holes 8a.

[0135] Thus, when the display panel 10 is in operation or affected by changes in the external environment, internal pressure changes may occur. The connecting hole 8a allows air or other media to circulate on both sides of the buffer layer 8, thereby balancing the pressure and preventing deformation or cracking of the buffer layer 8 or damage to other layers due to pressure differences, thereby improving the stability and reliability of the display panel 10.

[0136] In one embodiment, see [reference] Figure 8 As shown, the annular groove 11 includes a first groove sidewall 11a, a groove bottom wall 11c, and a second groove sidewall 11b; along the direction from the perforated area 10a to the first non-display area 10b, the first groove sidewall 11a and the second groove sidewall 11b are arranged opposite to each other and spaced apart; the groove bottom wall 11c is connected to the first groove sidewall 11a and the second groove sidewall 11b; the groove bottom wall 11c is located within the second sub-insulating layer 13; the first groove sidewall 11a includes a first sub-sidewall 11a1 and a second sub-sidewall 11a2, the first sub-sidewall 11a1 is located within the first sub-insulating layer 12, the second sub-sidewall 11a2 is located within the second sub-insulating layer 13, and the second sub-sidewall 11a2 is connected to the first sub-sidewall 11a1 and the groove bottom wall 11c.

[0137] Thus, the first groove sidewall 11a includes a first sub-sidewall 11a1 and a second sub-sidewall 11a2 located within different insulating layers 1 (first sub-insulating layer 12 and second sub-insulating layer 13). This layered structure also helps to disperse stress. Because the mechanical properties of different insulating layer 1 materials may be different, the layered structure allows the first groove sidewall 11a to better disperse stress through coordinated deformation between layers when subjected to stress, which can further enhance the stability of the display panel 10 structure and reduce the risk of cracking and deformation caused by stress concentration.

[0138] In one embodiment, the second groove sidewall 11b includes a third sub-sidewall 11b1 and a fourth sub-sidewall 11b2. The third sub-sidewall 11b1 is located within the first sub-insulating layer 12, and the fourth sub-sidewall 11b2 is located within the second sub-insulating layer 13. The fourth sub-sidewall 11b2 is connected to the third sub-sidewall 11b1 and the groove bottom wall 11c. The third sub-sidewall 11b1 is spaced apart from the first sub-sidewall 11a1, and the fourth sub-sidewall 11b2 is spaced apart from the second sub-sidewall 11a2.

[0139] Thus, the second groove sidewall 11b is composed of a third sub-sidewall 11b1 and a fourth sub-sidewall 11b2 located in different insulating layers 1. Corresponding to the layered structure of the first groove sidewall 11a, this layered design of the double sidewalls further optimizes the stress dispersion effect. When an external force is applied to the display panel 10, the multi-layered structure of the first groove sidewall 11a and the second groove sidewall 11b can distribute stress more precisely at different locations and between different material layers, enabling the entire annular groove 11 structure and even the display panel 10 to better withstand external forces, reducing the possibility of damage caused by stress concentration, and enhancing the stability and reliability of the structure.

[0140] In one embodiment, the distance between at least a portion of the first sub-sidewall 11a1 and at least a portion of the third sub-sidewall 11b1 is equidistant along the direction from the first surface 1a to the second surface 1b.

[0141] Thus, since the distance between at least a portion of the first sub-sidewall 11a1 and at least a portion of the third sub-sidewall 11b1 is equal everywhere along the direction from the first surface 1a to the second surface 1b, the uniformity of stress distribution can be further optimized. This is because the uniform spacing allows stress to be transmitted and distributed more smoothly between the first sub-sidewall 11a1 and the third sub-sidewall 11b1, avoiding stress concentration points caused by spacing changes. This further enhances the overall structure's ability to withstand external forces and reduces the possibility of cracking, deformation, or other problems caused by uneven stress distribution, thereby further improving the stability and reliability of the display panel 10.

[0142] In one embodiment, the distance between the first sub-sidewall 11a1 and the third sub-sidewall 11b1 is equal everywhere along the direction from the first surface 1a to the second surface 1b.

[0143] Thus, when the display panel 10 is subjected to external force, the equidistant structure can prevent stress concentration at certain specific points, allowing the stress to be more evenly distributed in the relevant area of ​​the entire annular groove 11, further enhancing the stability and reliability of the structure, effectively reducing problems such as cracking and deformation caused by stress concentration, thereby maximizing the stability and reliability of the display panel 10.

[0144] In one embodiment, the distance between at least a portion of the second sub-sidewall 11a2 and at least a portion of the fourth sub-sidewall 11b2 gradually increases along the direction from the first surface 1a to the second surface 1b.

[0145] Thus, along the direction from the first surface 1a to the second surface 1b, the distance between at least a portion of the second sub-sidewall 11a2 and at least a portion of the fourth sub-sidewall 11b2 gradually increases, forming a trapezoidal or conical groove structure. This gradually changing structure of at least a portion of the second sub-sidewall 11a2 and at least a portion of the fourth sub-sidewall 11b2 can better disperse stress. When an external force is applied to the display panel 10 itself, the gradually increasing dimensions of at least a portion of the second sub-sidewall 11a2 and at least a portion of the fourth sub-sidewall 11b2 enable the stress to be distributed more evenly on at least a portion of the second sub-sidewall 11a2 and at least a portion of the fourth sub-sidewall 11b2, avoiding stress concentration in a certain area, thereby enhancing the stability and reliability of the entire structure and reducing the probability of problems such as cracking and deformation caused by stress concentration.

[0146] Secondly, embodiments of this application provide a display device 100, including the display panel 10 described in the first aspect.

[0147] The display panel 10 provided in this embodiment includes an insulating layer 1 and a conductive element 2. The insulating layer 1 includes a first surface 1a and a second surface 1b that are disposed opposite to and spaced apart along the thickness direction of the insulating layer 1. The insulating layer 1 is provided with a through hole 1c that penetrates the insulating layer 1 along the thickness direction of the insulating layer 1. The orthographic projection of the through hole 1c on the plane of the first surface 1a coincides with the orthographic projection of the perforated area 10a on the plane of the first surface 1a. The insulating layer 1 is provided with an annular groove 11, the opening of which is located on the first surface 1a. The annular groove 11 is located in the first non-display area 10b and is disposed on the outer periphery of the perforated area 10a. The conductive element 2 is disposed on the side of the first surface 1a away from the second surface 1b. The conductive element 2 is located in the first non-display area 10b and is arranged around the outer periphery of the perforated area 10a. The orthographic projection of the conductive element 2 on the plane of the first surface 1a and the orthographic projection of the opening of the annular groove 11 on the plane of the first surface 1a are arranged along the direction from the perforated area 10a to the first non-display area 10b. Thus, an annular groove 11 is provided in the insulating layer 1, with the opening of the annular groove 11 located on the first surface 1a. The annular groove 11 is located in the first non-display area 10b and is disposed on the outer periphery of the perforated area 10a. Therefore, during the electrostatic conduction process, the annular groove 11 can increase the area of ​​electrostatic conduction on the first surface 1a, thereby reducing the area of ​​electrostatic conduction in other parts. Furthermore, since a conductive element 2 is provided on the side of the first surface 1a away from the second surface 1b, the conductive element 2 is located in the first non-display area 10b and is arranged around the outer periphery of the perforated area 10a. At the same time, the orthographic projection of the conductive element 2 on the plane of the first surface 1a and the orthographic projection of the opening of the annular groove 11 on the plane of the first surface 1a are arranged along the direction from the perforated area 10a to the first non-display area 10b. Therefore, the electrostatic charge conducted to the first surface 1a can be conducted away by the conductive element 2, thereby reducing the accumulation of electrostatic charge, blocking the conduction of electrostatic charge to the display area 10c of the display panel 10, ensuring the normal display of the display panel 10, and ultimately improving the display effect of the display device 100.
