[0002] OLED screens have circular holes cut into areas such as the camera aperture. To prevent water vapor from entering these holes, multiple metal rings are designed inside the holes to act as barriers, improving module reliability. However, this design carries the risk of attracting electrostatic discharge, which could damage the metal rings, causing black spots around the holes and affecting the normal display of the OLED screen. Summary of the Invention

[0003] Therefore, it is necessary to provide a display panel, display device, and method for manufacturing the display panel that can conduct away electrostatic discharge, prevent damage to the metal ring, and reduce the risk of black spots appearing around the hole area.

[0004] In a first aspect, embodiments of this application provide a display panel. The display panel includes a punched-out area, a first non-display area, and a display area; the first non-display area is disposed on at least a portion of the outer periphery of the punched-out area, and the display area is disposed on the side of the first non-display area opposite to the punched-out area; the display panel includes a display module, a resistive insulating layer, and a conductive element. The display module has a through-hole that penetrates the display module along its thickness direction, and the orthographic projection of the through-hole onto the plane of the display module coincides with the orthographic projection of the punched-out area onto the plane of the display module. At least a portion of the resistive insulating layer is disposed on the outer periphery of the punched-out area and within the display module of the first non-display area. The conductive element is electrically connected to the resistive insulating layer and the grounding wire of the display panel, and the sidewall of the resistive insulating layer facing the punched-out area is in contact with the conductive element.

[0059] Currently, OLED screens have circular holes cut into areas such as camera holes. To prevent water vapor from entering these holes, multiple metal rings are designed inside the holes to act as walls to block moisture, which can improve the reliability of the module.

[0060] It should be noted that this design carries the risk of attracting electrostatic discharge, which could cause the metal ring to explode, resulting in black spots around the hole area and affecting the normal display of the OLED screen.

[0061] Based on the above research, the applicant discovered that in the relevant technology, multiple signal lines are arranged at intervals, each signal line is located outside the hole area and arranged around the hole area, and multiple signal lines outside the hole area are connected to a metal ring and an external grounding wire is led out for static electricity discharge.

[0062] However, further research by the applicant revealed that the technical methods employed in the relevant technologies, on the one hand, require additional circuit design, increasing design costs; on the other hand, adding circuitry increases parasitic capacitance in the pixel area, affecting display quality. Parasitic capacitance refers to an unavoidable capacitive effect in electronic circuits caused by electric field coupling between conductors.

[0063] Firstly, referring to Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a display panel 10. The display panel 10 includes a punched area 10a, a first non-display area 10b, and a display area 10c; the first non-display area 10b is disposed on at least a portion of the outer periphery of the punched area 10a, and the display area 10c is disposed on the side of the first non-display area 10b opposite to the punched area 10a; the display panel 10 includes a display module 1, a resistive insulating layer 2, and a conductive element 3. The display module 1 is provided with a through hole 1a, which penetrates the display module 1 along the thickness direction of the display module 1, and the orthographic projection of the through hole 1a on the plane where the display module 1 is located coincides with the orthographic projection of the punched area 10a on the plane where the display module 1 is located. At least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the punched area 10a and within the display module 1 of the first non-display area 10b. The conductive element 3 is electrically connected to the resistive insulating layer 2 and the grounding wire of the display panel 10. The sidewall of the resistive insulating layer 2 facing the perforated area 10a is in contact with the conductive element 3. At least a portion of the conductive element 3 is located in the through hole 1a.

[0064] The display panel 10 provided in this embodiment includes a display module 1, a resistive insulating layer 2, and a conductive element 3. The display module 1 has a through-hole 1a that penetrates the display module 1 along its thickness direction. The orthographic projection of the through-hole 1a onto the plane of the display module 1 coincides with the orthographic projection of the cutout area 10a onto the plane of the display module 1. At least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the cutout area 10a and within the display module 1 of the first non-display area 10b. The conductive element 3 is electrically connected to the resistive insulating layer 2 and the grounding wire of the display panel 10. The sidewall of the resistive insulating layer 2 facing the cutout area 10a contacts the conductive element 3. At least a portion of the conductive element 3 is located within the through-hole 1a. Thus, the through hole 1a penetrates the display module 1 along the thickness direction of the display module 1, and at least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the cut-out area 10a. The resistive insulating layer 2 faces the side wall of the cut-out area 10a and contacts the conductive element 3. At least a portion of the conductive element 3 is located in the through hole 1a, so that the resistive insulating layer 2 and the grounding wire of the display panel 10 can be directly connected through the conductive element 3 located at least partially in the through hole 1a. This allows the static electricity of the resistive insulating layer 2 to be conducted away to the grounding wire, thus preventing the resistive insulating layer 2 from being damaged. This reduces the risk of black spots appearing in the display area 10c and improves the display effect of the display panel 10.

[0065] The through hole 1a penetrates the display module 1 along the thickness direction of the display module 1. The orthographic projection of the through hole 1a on the plane of the display module 1 coincides with the orthographic projection of the hole area 10a on the plane of the display module 1. That is, the through hole 1a forms the hole area 10a of the display module 1. The outer periphery of the through hole 1a is the first non-display area 10b and the display area 10c in sequence.

[0066] 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 at least part of 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.

[0067] Furthermore, since at least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the perforated area 10a and in the display module 1 of the first non-display area 10b, the resistive insulating layer 2 disposed on the outer periphery of the perforated area 10a can act as a wall to block water vapor, thereby ensuring the water vapor problem at the perforated area 10a and improving the reliability of the display module 1.

[0068] Since the conductive element 3 is electrically connected to the grounding wire of the resistive layer 2 and the display panel 10, the side wall of the resistive layer 2 facing the perforated area 10a is in contact with the conductive element 3. Thus, the resistive layer 2 and the grounding wire of the display panel 10 can be directly connected through the conductive element 3, thereby conducting the static electricity of the resistive layer 2 to the grounding wire. This can prevent the resistive layer 2 from being damaged by explosion, reduce the risk of black spots appearing in the display area 10c, and improve the display effect of the display panel 10.

[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 resistive layer 2, it can be directly conducted away by the conductive component 3 connected to the resistive layer 2. This can prevent the static electricity from accumulating in the resistive layer 2, prevent the resistive layer 2 from being damaged, or even damage the display area 10c, thereby ensuring the normal display of the display area 10c and improving the display effect of the display panel 10.

[0071] Furthermore, since at least a portion of the conductive element 3 is located within the through-hole 1a, on the one hand, during the fabrication of the conductive element 3, at least a portion of the conductive element 3 can be directly placed within the through-hole 1a, which facilitates the fabrication process and makes it easier for operators. On the other hand, no additional circuit design is required, and no design cost is increased; simply placing the conductive element 3 within the through-hole 1a simplifies the circuit design of the display panel 10 and reduces design costs.

[0072] Furthermore, by directly connecting the conductive element 3 to the grounding wire through the hole area 10a corresponding to the through hole 1a, the conductive element 3 does not need to be located in the first non-display area 10b on the outer periphery of the hole area 10a, which further simplifies the manufacturing process of the conductive element 3. Simultaneously, since the conductive element 3 does not pass through the first non-display area 10b and the display area 10c, the static electricity path during the static discharge process can be avoided between the first non-display area 10b and the display area 10c. This further ensures the stability and reliability of the static electricity discharge process, further dissipates static electricity from the conductive element 2, further prevents damage to the conductive element 2, further reduces the risk of black spots appearing in the display area 10c, and improves the display effect of the display panel 10.

[0073] In one embodiment, see [reference] Figure 4 As shown, the display module 1 includes a display screen 11; the through hole 1a includes a first sub-through hole 1a1; the first sub-through hole 1a1 penetrates the display screen 11 along the thickness direction of the display module 1; the orthographic projection of the first sub-through hole 1a1 on the plane where the display module 1 is located coincides with the orthographic projection of the hole area 10a on the plane where the display module 1 is located.

[0074] Thus, since the first sub-through hole 1a1 penetrates the display screen 11 along the thickness direction of the display module 1 and its orthographic projection coincides with the perforated area 10a, it can provide installation positions for other components within a limited space, effectively utilizing the internal space of the display module 1. This allows the display panel 10 to integrate more functional components while maintaining its thinness, thereby improving the compactness and functionality of the device.

[0075] Furthermore, the first sub-through hole 1a1 coincides with the orthographic projection of the punch-hole area 10a, which makes the display structure of the display screen 11 in the punch-hole area 10a more regular. When displaying images, it can ensure that the pixel arrangement and display effect around the punch-hole area 10a are relatively uniform, reducing display abnormalities that may be caused by the inconsistency between the position of the through hole 1a and the punch-hole area 10a, such as light leakage and uneven pixel display, thereby improving the display quality and visual effect of the entire display screen 11.

[0076] In one embodiment, see [reference] Figure 4 As shown, the display module 1 also includes a support layer 12; the support layer 12 is disposed on one side of the thickness direction of the display screen 11, and the support layer 12 is spaced apart from the conductive barrier layer 2; the through hole 1a also includes a second sub-through hole 1a2; the second sub-through hole 1a2 penetrates the support layer 12 along the thickness direction of the display module 1; the orthographic projection of the second sub-through hole 1a2 on the plane where the display module 1 is located coincides with the orthographic projection of the hole area 10a on the plane where the display module 1 is located, and the first sub-through hole 1a1 and the second sub-through hole 1a2 are connected.

[0077] Thus, since the orthographic projection of the second sub-through hole 1a2 coincides with the cutout area 10a and is connected to the first sub-through hole 1a1, it can provide precise positioning for specific components (such as cameras, sensors, etc.) installed on the display module 1. This allows these components to be accurately placed in the corresponding positions of the cutout area 10a through the first sub-through hole 1a1 and the second sub-through hole 1a2 during installation, ensuring the accuracy and consistency of component installation, thereby ensuring that they can function properly. For example, the camera can accurately capture the required image, and the sensor can accurately collect the corresponding data.

[0078] Furthermore, the support layer 12 itself serves to support the display screen 11, and the design of the second sub-through hole 1a2 can provide an installation channel for specific components without affecting the support function. At the same time, since the second sub-through hole 1a2 is connected to the first sub-through hole 1a1, a relatively stable overall structure can be formed after the components are installed, further enhancing the stability of the display module 1.

[0079] In one embodiment, the conductive element 3 is located in the first sub-through hole 1a1 extending to the second sub-through hole 1a2, and the conductive element 3 is connected to the support layer 12.

[0080] Thus, the conductive element 3 connects the first sub-through hole 1a1 and the second sub-through hole 1a2, penetrating the display screen 11 and the support layer 12, providing a conduction path from the surface of the display screen 11 to the support layer 12 for electrostatic discharge. When static electricity is generated on the surface of the display screen 11 for various reasons, the static electricity can be quickly conducted to the support layer 12 through the conductive element 3, preventing the accumulation of static electricity on the surface of the display screen 11. It can also conduct away the static electricity in the resistive insulating layer 2, preventing the resistive insulating layer 2 from being damaged, reducing the risk of black spots appearing in the display area 10c, and improving the display effect of the display panel 10.

[0081] In one embodiment, the support layer 12 is made of a conductive material.

[0082] Thus, the support layer 12 made of conductive material can act as a good conductor of static electricity, quickly conducting away the static electricity generated by components such as the display screen 11 and the static electricity conducted to the conductive barrier layer 2, preventing the accumulation of static electricity, avoiding problems such as display abnormalities and circuit damage caused by electrostatic discharge, and improving the stability and reliability of the display panel 10.

[0083] In one embodiment, the support layer 12 is made of copper.

[0084] Thus, due to copper's excellent conductivity, it can quickly and effectively conduct static electricity, rapidly guiding the static electricity generated in display module 1 to the ground or other grounded parts, preventing static electricity accumulation from damaging display screen 11 and other components. Simultaneously, as a carrier of electrical connections, it ensures stable current transmission, reduces resistance, minimizes energy loss, and guarantees good electrical connections between electronic components in display module 1, contributing to improved overall performance and stability of display module 1.

[0085] In one embodiment, the ground wire of the display panel 10 is connected to the support layer 12.

[0086] Thus, static electricity will inevitably be generated during the operation of the display panel 10. Connecting the grounding wire to the support layer 12 can provide a low-resistance discharge path for static electricity, allowing it to be quickly conducted to the ground through the support layer 12. This can prevent static electricity from accumulating on the display panel 10 and avoid damage to the internal circuits and components of the display panel 10 caused by electrostatic discharge, thereby improving the stability and reliability of the display panel 10.

[0087] Meanwhile, since the conductive element 3 is electrically connected to the grounding wire of the resistive insulating layer 2 and the display panel 10, and the grounding wire of the display panel 10 is connected to the support layer 12, the conductive element 3 can bypass the first non-display area 10b and the display area 10c. This avoids the static electricity passing through the first non-display area 10b and the display area 10c during the static electricity conduction process, thereby further ensuring the stability and reliability of the static electricity conduction process, further conducting away the static electricity of the resistive insulating layer 2, further preventing the resistive insulating layer 2 from being damaged, further reducing the risk of black spots appearing in the display area 10c, and improving the display effect of the display panel 10.

[0088] In one embodiment, see [reference] Figure 4 As shown, the display module 1 also includes an adhesive layer 13; the adhesive layer 13 is disposed between the display screen 11 and the support layer 12; the through hole 1a also includes a third sub-through hole 1a3; the third sub-through hole 1a3 penetrates the adhesive layer 13 along the thickness direction of the display module 1; the orthographic projection of the third sub-through hole 1a3 on the plane where the display module 1 is located coincides with the orthographic projection of the hole area 10a on the plane where the display module 1 is located, and the third sub-through hole 1a3 is connected to the first sub-through hole 1a1 and the second sub-through hole 1a2.

[0089] Thus, the third sub-through hole 1a3 provides a continuous channel for the conductive element 3, allowing the conductive element 3 to extend smoothly from the display screen 11 to the support layer 12. This ensures that static electricity can be conducted from the surface of the display screen 11 through the first sub-through hole 1a1, the third sub-through hole 1a3, and the second sub-through hole 1a2, and finally to the support layer 12, forming a complete static electricity discharge path. This effectively prevents static electricity from accumulating near the display screen 11 or the adhesive layer 13, protecting the performance and stability of the display module 1.

[0090] Meanwhile, the display screen 11 and the support layer 12 can be firmly bonded together by the adhesive layer 13, and the presence of the third sub-through hole 1a3 will not damage the overall structural function of the adhesive layer 13. At the same time, it allows the conductive component 3 to pass through, achieving electrical connection while ensuring the mechanical connection strength between the display screen 11 and the support layer 12, so that the display module 1 is not prone to delamination or loosening during long-term use.

[0091] In one embodiment, the conductive element 3 is located in the first sub-through hole 1a1 extending to the third sub-through hole 1a3, and the conductive element 3 is connected to the adhesive layer 13.

[0092] Thus, since the conductive element 3 connects the first sub-through hole 1a1 and the third sub-through hole 1a3, the static electricity generated on the display screen 11 and the static electricity conducted to the conductive barrier layer 2 can be quickly conducted to the adhesive layer 13 through the conductive element 3. Since the adhesive layer 13 is located between the display screen 11 and the support layer 12, the static electricity can be further discharged through the support layer 12 and other pathways, thereby avoiding the local accumulation of static electricity on the display screen 11 and preventing static electricity from damaging the display module 1.

[0093] Optionally, the display module 1 also includes a waterproof coating. The waterproof coating is applied to the side of the conductive insulating layer 2, the support layer 12 and the adhesive layer 13 facing the through hole 1a, thereby achieving a waterproof effect and ensuring the normal use of the display panel 10.

[0094] In one embodiment, see [reference] Figure 5 As shown, the display panel 10 also includes an encapsulation layer 14; the encapsulation layer 14 is disposed on the side of the display screen 11 away from the support layer 12; the through hole 1a also includes a fourth sub-through hole 1a4; the fourth sub-through hole 1a4 penetrates the encapsulation layer 14 along the thickness direction of the display module 1; the orthographic projection of the fourth sub-through hole 1a4 on the plane where the display module 1 is located coincides with the orthographic projection of the punched area 10a on the plane where the display module 1 is located, and the fourth sub-through hole 1a4 is connected to the first sub-through hole 1a1.

[0095] Thus, the encapsulation layer 14 is located on the side of the display screen 11 opposite to the support layer 12, and is the outermost protective structure of the display panel 10. The presence of the fourth sub-via 1a4 allows static electricity to be conducted from the surface of the display screen 11 through the fourth sub-via 1a4, the first sub-via 1a1, and then through the third sub-via 1a3 and the second sub-via 1a2 to the support layer 12, forming a complete static electricity discharge path from the surface of the display panel 10 to the support layer 12. This can more effectively discharge the static electricity generated by the display panel 10 during operation, preventing static electricity accumulation from damaging the internal circuits and components of the display panel 10, and ensuring the normal operation and service life of the display panel 10.

[0096] In one embodiment, the conductive element 3 is located in the first sub-via 1a1 extending to the fourth sub-via 1a4, and the conductive element 3 is connected to the encapsulation layer 14.

[0097] Thus, since the conductive component 3 is connected to the encapsulation layer 14, the static electricity that may be conducted from the surface of the encapsulation layer 14 and the display screen 11 to the encapsulation layer 14 can be quickly conducted away through the channel formed by the first sub-through hole 1a1 and the fourth sub-through hole 1a4, avoiding the accumulation of static electricity in the encapsulation layer 14. The static electricity of the resistive barrier layer 2 can be conducted away, preventing the resistive barrier layer 2 from being damaged. This can reduce the risk of black spots appearing in the display area 10c and improve the display effect of the display panel 10.

[0098] In one embodiment, see [reference] Figure 5 As shown, the display panel 10 also includes a cover plate 15; the cover plate 15 is disposed on the side of the encapsulation layer 14 opposite to the display screen 11.

[0099] Thus, on the one hand, the cover plate 15 is usually made of a material with high hardness, such as glass or special plastic, which can withstand friction and scratches during daily use, preventing the surface of the display screen 11 from being scratched by sharp objects such as keys and jewelry, and maintaining the integrity and display effect of the display screen 11. On the other hand, the cover plate 15 can isolate the display screen 11 from the external environment, preventing dust, moisture, oil and other contaminants from contacting the display screen 11, avoiding problems such as affecting display quality or causing short circuits in the internal circuitry of the display screen 11 due to the accumulation of contaminants.

[0100] In one embodiment, see [reference] Figure 3 As shown, the display panel 10 also includes a second non-display area 10d, at least a portion of which is located on the outer periphery of the display area 10c.

[0101] Thus, since the display area 10c is the core functional area of ​​the display panel 10, the second non-display area 10d surrounds it, serving to reinforce and protect the structure, enhancing the overall strength of the display panel 10 and preventing the display area 10c from being easily damaged by external impacts. Furthermore, the second non-display area 10d also protects the edges of the display area 10c, preventing electrical performance degradation or exposure to external environmental factors due to edge exposure.

[0102] In one embodiment, see [reference] Figure 6 As shown, the conductive barrier layer 2 includes multiple barrier rings 21, which are sequentially nested from the inside to the outside, with adjacent barrier rings 21 spaced apart.

[0103] Thus, when static electricity is generated, the barrier rings 21 can disperse the static electricity to each barrier ring 21, preventing the static electricity from concentrating at a certain point or in a certain area. The spacing between adjacent barrier rings 21 provides a conduction path for the static electricity, allowing the static electricity to be evenly conducted along the distribution of the barrier rings 21, and finally discharged through grounding or other means, thereby reducing the damage of static electricity to the display module 1.

[0104] Furthermore, it should be noted that when static electricity is generated, due to the inherent characteristics of static electricity conduction, the static electricity will preferentially conduct to the nearest barrier ring 21. Only if the barrier ring 21 is insufficient to continue absorbing static electricity will the static electricity continue to conduct to other barrier rings 21. Since the barrier ring 21 is connected to the grounding wire through the conductive element 3, the static electricity conducted to the nearest barrier ring 21 can be conducted to the grounding wire through the conductive element 3.

[0105] As can be seen from the above description, since multiple barrier rings 21 are sequentially nested from the inside to the outside, and adjacent barrier rings 21 are spaced apart, static electricity can be directly discharged through the nearest barrier ring 21. The other nested barrier rings 21 can further act as walls to block water vapor, which can ensure the water vapor problem at the hole area 10a, thereby improving the reliability of the display module 1.

[0106] In one embodiment, at least a portion of the barrier ring 21 has the same difference between its outer diameter and its inner diameter.

[0107] Thus, since the difference between the outer and inner diameters of at least some of the barrier rings 21 is the same, barrier rings 21 of the same width can provide a uniform electrostatic conduction path for electrostatic discharge. When static electricity is distributed on the barrier rings 21, because the barrier rings 21 have a uniform width, the static electricity can be distributed more evenly on each barrier ring 21, avoiding the situation where static electricity is too concentrated in certain areas. At the same time, the uniform spacing between adjacent barrier rings 21 also makes the conduction of static electricity between adjacent barrier rings 21 more stable and uniform, which is conducive to quickly and effectively guiding static electricity to the grounding wire, thereby better protecting the display panel 10 from electrostatic damage.

[0108] In one embodiment, the conductive barrier 2 is disposed within the display screen 11.

[0109] Thus, during the use of the display screen 11, static electricity is easily generated due to friction, induction, and other reasons. If too much static electricity accumulates, it will damage the film layer inside the display screen 11, affecting its performance and lifespan. The conductive barrier layer 2 can conduct away the generated static electricity in a timely manner, preventing it from accumulating inside the display screen 11, thereby protecting the sensitive components inside the display screen 11 and improving its reliability and stability.

[0110] In one embodiment, the conductive barrier 2 is disposed outside the display screen 11 and is located on the side of the display screen 11 opposite to the support layer 12.

[0111] Thus, since the conductive resistive barrier 2 is disposed outside the display screen 11 and located on the side of the display screen 11 away from the support layer 12, the conductive resistive barrier 2 can also serve as an outer protective layer for the display screen 11, allowing it to more directly contact any static electricity that may be generated in the external environment. When static electricity is generated, it can quickly conduct the static electricity, preventing the accumulation of static electricity on the surface of the display screen 11, thereby preventing static electricity from damaging the internal components of the display screen 11 and protecting the normal operation of the display screen 11.

[0112] In one embodiment, see [reference] Figure 6 As shown, the conductive barrier layer 2 also includes a connector 22, which is connected to at least two partially adjacent barrier rings 21.

[0113] In this way, connecting adjacent barrier rings 21 together can enhance the overall structural strength of the conductive barrier layer 2, thereby preventing the barrier rings 21 from shifting, deforming or falling off when subjected to external forces. This allows the conductive barrier layer 2 to better withstand various stresses during the production, assembly and use of the display screen 11, protecting the performance and reliability of the display screen 11.

[0114] In one embodiment, there are multiple connectors 22 between two adjacent barrier rings 21, and the multiple connectors 22 are arranged at circumferential intervals along the perforated area 10a.

[0115] Thus, since the connectors 22 are evenly spaced along the circumference of the perforated area 10a, when static electricity is generated, it can be more evenly distributed to the adjacent barrier rings 21 through these evenly distributed connectors 22, thereby further preventing static electricity from accumulating in local areas, further dissipating static electricity from the conductive layer 2, further preventing the conductive layer 2 from being damaged, further reducing the risk of black spots appearing in the display area 10c, and further improving the display effect of the display panel 10.

[0116] In one embodiment, see [reference] Figure 6 As shown, the plurality of barrier rings 21 include a first barrier ring 211, a second barrier ring 212 and a third barrier ring 213 arranged sequentially from the inside to the outside. The connector 22 between the first barrier ring 211 and the second barrier ring 212 is a first connector 221, and the connector 22 between the second barrier ring 212 and the third barrier ring 213 is a second connector 222. There is at least one first connector 221 and at least one second connector 222. At least one first connector 221 and at least one second connector 222 are staggered along the direction from the perforated area 10a to the first non-display area 10b.

[0117] Thus, on the one hand, during the electrostatic discharge process, the staggered arrangement requires the static electricity to be transferred along different paths through the connectors 22 between the barrier rings 21 during conduction. This allows for more even distribution of static electricity, preventing its concentration in localized areas, reducing the risk of damage to the internal components of the display screen 11, and improving electrostatic protection performance. On the other hand, the staggered connectors 22 increase the complexity and diversity of the connections between the barrier rings 21, enabling more even distribution of external forces. When the conductive barrier layer 2 is subjected to external stress, the connectors 22 at different positions can work together to bear and transmit the force, thereby improving the stability and strength of the entire structure, preventing the barrier rings 21 from deforming or being damaged due to uneven stress, and ultimately improving the stability and reliability of the display panel 10.

[0118] In one embodiment, all first connectors 221 and all second connectors 222 are staggered along the direction from the cutout area 10a to the first non-display area 10b.

[0119] In this way, the staggered arrangement of all connectors 22 provides more diverse conduction paths for static electricity, allowing static electricity to diffuse and transfer more fully between the barrier rings 21. This enables the static electricity to be guided to the grounding wire more quickly and thoroughly, minimizing the accumulation of static electricity within the display screen 11. This further reduces the risk of black spots appearing in the display area 10c and improves the display effect of the display panel 10.

[0120] In one embodiment, the conductive element 3 covers at least a portion of the inner sidewall of the through hole 1a.

[0121] Thus, since the conductive element 3 covers at least part of the inner wall of the through hole 1a, on the one hand, the conductive element 3 can be directly fabricated on the inner wall of the through hole 1a, which facilitates the fabrication process of the conductive element 3. On the other hand, it can increase the contact area between the conductive element 3 and the resistive layer 2, thereby further enhancing the effect of discharging static electricity from the resistive layer 2, and better discharging the static electricity from the resistive layer 2, thus improving the display effect of the display panel 10.

[0122] In one embodiment, the conductive element 3 located in the through hole 1a is annular in shape, and the conductive element 3 covers the entire inner wall of the through hole 1a.

[0123] Thus, since the conductive element 3 located in the through hole 1a is annular in shape and covers the entire inner wall of the through hole 1a, on the one hand, the conductive element 3 can be directly fabricated on the inner wall of the through hole 1a, which makes the fabrication process of the conductive element 3 more convenient. On the other hand, it can further increase the contact area between the conductive element 3 and the resistive layer 2, so that the contact area between the conductive element 3 and the resistive layer 2 reaches the maximum, thereby further enhancing the effect of discharging static electricity in the resistive layer 2, and better discharging the static electricity from the resistive layer 2, thus improving the display effect of the display panel 10.

[0124] In one embodiment, the conductive element 3 located in the through hole 1a is in the shape of a straight line and extends along the thickness direction of the display module 1.

[0125] Thus, since the conductive element 3 located in the through hole 1a is in the shape of a straight line and extends along the thickness direction of the display module 1, it is only necessary to prepare the conductive element 3 in the shape of a straight line. In this way, while the conductive element 3 realizes the discharge of static electricity from the conductive layer 2, the preparation process of the conductive element 3 can be made as convenient as possible.

[0126] In one embodiment, see [reference] Figure 7As shown, along the thickness direction of the display module 1, the orthographic projection of the sidewall of the conductive insulating layer 2 facing the perforated area 10a on the plane of the display module 1 is spaced apart from the orthographic projection of the perforated area 10a on the plane of the display module 1.

[0127] Thus, because the orthographic projection of the sidewall of the resistive insulating layer 2 facing the punched area 10a on the plane of the display module 1 is spaced apart from the orthographic projection of the punched area 10a on the plane of the display module 1, the sidewall of the resistive insulating layer 2 facing the punched area 10a is recessed within the display module 1. Furthermore, since the punched area 10a of the display module 1 is typically used to house critical components such as cameras, the recessed sidewall of the resistive insulating layer 2 prevents it from directly contacting the components in the punched area 10a. This prevents the resistive insulating layer 2 from causing damage such as compression, wear, or short circuits to these components during the assembly or use of the display module 1, thereby protecting the performance and safety of the components in the punched area 10a.

[0128] In one embodiment, see [reference] Figure 7 As shown, the conductive component 3 includes a first conductive part 31 and a second conductive part 32; the first conductive part 31 is connected to the sidewall of the conductive layer 2 facing the hole area 10a and the second conductive part 32; along the thickness direction of the display module 1, the orthographic projection of the first conductive part 31 on the plane where the display module 1 is located is within the orthographic projection of the first non-display area 10b on the plane where the display module 1 is located; the orthographic projection of the second conductive part 32 on the plane where the display module 1 is located is within the orthographic projection of the hole area 10a on the plane where the display module 1 is located.

[0129] Thus, the first conductive part 31 connects the resistive insulating layer 2 and the second conductive part 32, providing a more stable connection for the entire structure. This allows for a tighter bond between the resistive insulating layer 2 and the perforated area 10a and the first non-display area 10b. When the display module 1 is subjected to external impact or vibration, it can better withstand stress, reduce relative displacement and loosening between components, and improve the structural stability and reliability of the display module 1.

[0130] In one embodiment, along the thickness direction of the display module 1, the orthographic projection of the sidewall of the conductive barrier layer 2 facing the punched area 10a onto the plane of the display module 1 coincides with the outer contour of the orthographic projection of the punched area 10a onto the plane of the display module 1.

[0131] Thus, because the orthographic projection of the sidewall of the conductive resistive layer 2 facing the punched area 10a on the plane of the display module 1 coincides with the outer contour of the orthographic projection of the punched area 10a on the plane of the display module 1, that is, the sidewall of the conductive resistive layer 2 facing the punched area 10a is flush with the sidewall of the punched area 10a of the display module 1, on the one hand, it makes the appearance around the punched area 10a smoother and more even, without abrupt height differences, improving the overall aesthetics. On the other hand, it makes it easier to achieve precise alignment and installation during the production and assembly process, reducing assembly difficulty and improving production efficiency. At the same time, it also helps to ensure product consistency and stability, reducing various problems caused by installation errors.

[0132] In one embodiment, see [reference] Figure 8 As shown, along the thickness direction of the display module 1, the orthographic projection of the sidewall of the conductive insulating layer 2 facing the perforated area 10a onto the plane where the display module 1 is located is within the orthographic projection of the perforated area 10a onto the plane where the display module 1 is located.

[0133] Thus, since the orthographic projection of the sidewall of the resistive insulating layer 2 facing the perforated area 10a on the plane of the display module 1 along the thickness direction of the display module 1 is located within the orthographic projection of the perforated area 10a on the plane of the display module 1, that is, the sidewall of the resistive insulating layer 2 facing the perforated area 10a is set in the through hole 1a and protrudes from the sidewall of the perforated area 10a of the display module 1, the resistive insulating layer 2 can have a larger contact space with static electricity, thereby increasing the possibility of static electricity being conducted to the resistive insulating layer 2. Furthermore, the static electricity of the resistive insulating layer 2 can be further conducted away by the conductive component 3, preventing the resistive insulating layer 2 from being damaged, reducing the risk of black spots appearing in the display area 10c, and improving the display effect of the display panel 10.

[0134] Secondly, see Figure 9 As shown, this application embodiment provides a display device 100, including the display panel 10 in the first aspect.

[0135] The display device 100 provided in this application embodiment includes a display panel 10. The display panel 10 includes a display module 1, a resistive insulating layer 2, and a conductive element 3. The display module 1 is provided with a through hole 1a, which penetrates the display module 1 along its thickness direction. The orthographic projection of the through hole 1a on the plane where the display module 1 is located coincides with the orthographic projection of the cutout area 10a on the plane where the display module 1 is located. At least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the cutout area 10a and within the display module 1 of the first non-display area 10b. The conductive element 3 is electrically connected to the resistive insulating layer 2 and the grounding wire of the display panel 10. The sidewall of the resistive insulating layer 2 facing the cutout area 10a is in contact with the conductive element 3. At least a portion of the conductive element 3 is located within the through hole 1a. Thus, the through hole 1a penetrates the display module 1 along the thickness direction of the display module 1, and at least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the cut-out area 10a. The resistive insulating layer 2 faces the side wall of the cut-out area 10a and contacts the conductive element 3. At least a portion of the conductive element 3 is located in the through hole 1a, so that the resistive insulating layer 2 and the grounding wire of the display panel 10 can be directly connected through the conductive element 3 located at least partially in the through hole 1a. This allows the static electricity of the resistive insulating layer 2 to be conducted away to the grounding wire, preventing the resistive insulating layer 2 from being damaged. This reduces the risk of black spots appearing in the display area 10c, improves the display effect of the display panel 10, and ultimately improves the display effect of the display device 100.

[0136] It is understood that the display device 100 in the embodiments of this application may be a laptop computer, mobile phone, wireless device, personal digital assistant (PDA), handheld or portable computer, GPS receiver / navigator, camera, MP4 video player, camcorder, game console, watch, clock, calculator, TV monitor, flat panel display, computer monitor, car display (e.g., odometer display, etc.), navigator, cockpit controller and / or display, display of camera view (e.g., display of rearview camera in a vehicle), electronic photograph, electronic billboard or sign, front projector, etc.

[0137] Thirdly, see Figure 10 As shown, this application embodiment provides a method for manufacturing a display panel 10. The display panel 10 includes a punched area 10a, a first non-display area 10b, and a display area 10c. The first non-display area 10b is disposed on at least a portion of the outer periphery of the punched area 10a, and the display area 10c is disposed on the side of the first non-display area 10b opposite to the punched area 10a. The method for manufacturing the display panel 10 includes the following steps:

[0138] S100: A display module and a resistive insulating layer are formed; the display module is provided with a through hole, which penetrates the display module along the thickness direction, and the orthographic projection of the through hole on the plane where the display module is located coincides with the orthographic projection of the cut-out area on the plane where the display module is located; the resistive insulating layer is located in the display module, at least part of the resistive insulating layer is provided on the outer periphery of the cut-out area, and the resistive insulating layer is located in the first non-display area;

[0139] S200: At least a portion of a conductive element is formed in the through hole; the conductive element is electrically connected to the resistive insulating layer and the grounding wire of the display panel, and the resistive insulating layer is in contact with the conductive element on the side wall facing the hole area.

[0140] The display panel 10 provided in this embodiment includes a display module 1, a resistive insulating layer 2, and a conductive element 3. The display module 1 has a through-hole 1a that penetrates the display module 1 along its thickness direction. The orthographic projection of the through-hole 1a onto the plane of the display module 1 coincides with the orthographic projection of the cutout area 10a onto the plane of the display module 1. At least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the cutout area 10a and within the display module 1 of the first non-display area 10b. The conductive element 3 is electrically connected to the resistive insulating layer 2 and the grounding wire of the display panel 10. The sidewall of the resistive insulating layer 2 facing the cutout area 10a contacts the conductive element 3. At least a portion of the conductive element 3 is located within the through-hole 1a. Thus, the through hole 1a penetrates the display module 1 along the thickness direction of the display module 1, and at least a portion of the resistive insulating layer 2 is disposed on the outer periphery of the cut-out area 10a. The resistive insulating layer 2 faces the side wall of the cut-out area 10a and contacts the conductive element 3. At least a portion of the conductive element 3 is located in the through hole 1a, so that the resistive insulating layer 2 and the grounding wire of the display panel 10 can be directly connected through the conductive element 3 located at least partially in the through hole 1a. This allows the static electricity of the resistive insulating layer 2 to be conducted away to the grounding wire, thus preventing the resistive insulating layer 2 from being damaged. This reduces the risk of black spots appearing in the display area 10c and improves the display effect of the display panel 10.

[0141] In one embodiment, see [reference] Figure 11 and Figure 12 As shown, forming a display module and a conductive barrier layer includes the following steps:

[0142] S110: Form an initial display module and an initial conductive barrier layer. The initial display module is located in the cutout area, the first non-display area and the display area. The initial conductive barrier layer is located in the cutout area and the first non-display area.

[0143] S120: Remove the initial display module and the initial conductive layer located in the hole area to form a through hole in the initial display module, retain the initial conductive layer located in the first non-display area to form a conductive layer, and retain the initial display module located in the first non-display area and the display area to form a display module.

[0144] Thus, by removing the initial display module and the initial resistive insulating layer located in the cutout area 10a to form a through hole 1a in the initial display module, and retaining the initial resistive insulating layer located in the first non-display area 10b to form a resistive insulating layer 2, the resistive insulating layer 2 can be exposed on the side wall facing the cutout area 10a. The exposed resistive insulating layer 2 and the grounding wire can then be directly connected by the conductive element 3. This facilitates the connection between the conductive element 3 and the exposed resistive insulating layer 2 and the grounding wire. Furthermore, the conductive element 3 can conduct away static electricity from the resistive insulating layer 2, preventing damage to the resistive insulating layer 2. This reduces the risk of black spots appearing in the display area 10c and improves the display effect of the display panel 10.

[0145] Furthermore, since only a portion of the conductive element 3 needs to be located in the through hole 1a, and the exposed conductive layer 2 and the grounding wire are directly connected through the conductive element 3, no additional circuit design is required, and no design cost is increased. The circuit design of the display panel 10 can be simplified and the design cost can be reduced simply by placing the conductive element 3 in the through hole 1a.

[0146] Meanwhile, since the conductive component 3 does not pass through the first non-display area 10b and the display area 10c, the static electricity can be prevented from passing through the first non-display area 10b and the display area 10c during the static electricity conduction process. This further ensures the stability and reliability of the static electricity conduction process, further conducts away the static electricity of the resistive layer 2, further prevents the resistive layer 2 from being damaged, further reduces the risk of black spots appearing in the display area 10c, and improves the display effect of the display panel 10.

[0147] It should be noted that the initial display module and the initial conductive layer located in the cut-out area 10a can be removed by drilling or punching. Of course, other methods can also be used to remove the initial display module and the initial conductive layer located in the cut-out area 10a. Here, this application does not limit or elaborate on the method of removing the initial display module and the initial conductive layer located in the cut-out area 10a.
