DETAILED DESCRIPTION

[0041] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0043] It should be understood that when an element or layer is referred to as "on ...", "adjacent to ...", "connected to" or "coupled to" other elements or layers, it can be directly on, adjacent to, connected to or coupled to other elements or layers, or there can be intervening elements or layers. On the contrary, when an element is referred to as "directly on ...", "directly adjacent to ...", "directly connected to" or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. can be used to describe various elements, components, regions, layers, doping types and / or parts, these elements, components, regions, layers, doping types and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, doping type or part from another element, component, region, layer, doping type or part. Therefore, without departing from the teachings of the present invention, the first element, component, region, layer, doping type or portion discussed below may be represented as a second element, component, region, layer or portion; for example, the first doping type may be referred to as the second doping type, and similarly, the second doping type may be referred to as the first doping type; the first doping type and the second doping type are different doping types, for example, the first doping type may be P-type and the second doping type may be N-type, or the first doping type may be N-type and the second doping type may be P-type.

It should be understood that, in addition to the orientations shown in the figures, spatially relative terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0045] When used herein, the singular forms "a", "an" and " / the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof. At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.

[0046] With the development and progress of display technologies such as flexible display panels, the requirements for display quality of display panels and display devices have increased. During the preparation of display panels, a certain amount of static charge is usually generated between different film layers of the display panel.

[0047] It should be noted that during the preparation of the display panel, a certain amount of static charge is usually generated between different film layers of the display panel, especially on the surface of the organic material layer. Therefore, when the display panel is lit, especially when the 4KV test is performed, the static charge inside the display panel will move under the action of the external electric field. Since the dielectric constant of inorganic materials is large, the static charge inside the display panel will usually migrate from between the organic film layers in the cutting path of the display panel under the action of the external electric field until it is discharged.

[0048] However, the conductivity of organic materials is relatively poor, and the migration and extraction path of static charge inside the display panel is long, which will result in a slow extraction speed of static charge. At the same time, under the action of an external electric field, static charge will accumulate, so that the extraction speed of static charge is lower than the accumulation speed of static charge, causing the accumulation of static charge to gradually increase, causing static charge to interfere with the light-emitting elements and circuit structures in the display panel, increasing the safety risk of the display panel, and causing static charge to interfere with the transmission of electrical signals in the display panel, causing display problems such as abnormal or chaotic display of the display screen of the display panel, resulting in reduced accuracy and stability of the display panel, affecting the display effect and display quality of the display panel.

[0049] In view of this, the embodiments of the present application provide a display panel and a method for preparing a display panel, which can reduce the interference of electrostatic charges in the display panel on electrical signals in the display panel, reduce the risk of abnormal and chaotic display of the display panel, protect the light-emitting elements and circuit structures in the display panel, improve the safety of the display panel, improve the accuracy and stability of the displayed image, and improve the display quality of the display panel.

[0050] FIG1 is a schematic structural diagram of a display panel provided in an embodiment of the present application. As shown in FIG1 , in a first aspect of an embodiment of the present application, a display panel is provided, the display panel includes a display area 101 and a non-display area 102, and the display panel includes: a substrate 100, a light-emitting layer 200, an encapsulation layer 300, and a conductive structure 400. Among them, the substrate 100 at least includes an organic substrate 110; the light-emitting layer 200 is located on one side of the substrate 100, and the light-emitting layer 200 is located in the display area 101; the encapsulation layer 300 is located on the surface of the side of the light-emitting layer 200 away from the substrate 100, and the encapsulation layer 300 is located in the non-display area 102; the conductive structure 400 is located in the non-display area 102, the conductive structure 400 at least penetrates the encapsulation layer 300, the conductive structure 400 is in contact with the organic substrate 110, and the conductive structure 400 is used for grounding.

[0051] For example, the material of the conductive structure 400 may include a metal material. The substrate 100 may include a flexible substrate, and the material of the organic substrate 110 may include polyimide.

[0052] Exemplarily, in the direction from the display area 101 to the non-display area 102, the conductive structure 400 may include a plurality of conductive structures, and each conductive structure 400 is insulated from each other. Different conductive structures 400 may include different conductive materials. For example, the conductive material included in the conductive structure 400 farthest from the light-emitting layer 200 has the best conductivity, so that during the process of the static charge of the cutting path in the non-display area 102 migrating to the display area 101, the static charge can be quickly discharged at the end far away from the display area 101, further improving the conductive effect of the conductive structure 400.

[0053] It should be noted that, in the case where the substrate 100 includes an organic substrate 110, the organic substrate 110 is more likely to generate and accumulate static charges during the preparation and professional processes. Therefore, by contacting the conductive structure 400 with the organic substrate 110, the conductive structure 400 can extract and release the static charges on the organic substrate 110, thereby preventing the static charges from migrating within the display panel and affecting other electronic devices within the display panel. This can increase the amount of static charges extracted within the display panel and further suppress the electrostatic interference of the display panel.

[0054] The display panel provided in the embodiment of the present application is provided with a conductive structure 400 penetrating the encapsulation layer 300, so that one end of the conductive structure 400 is used to contact the organic substrate 110 in the substrate 100, and the other end of the conductive structure 400 is used to be grounded, so that the conductive structure 400 can extract and release the static charge of the organic substrate 110. Therefore, the extraction speed of the static charge can be accelerated, and under the action of the external electric field, the extraction speed of the static charge in the display panel can be made greater than the accumulation speed of the static charge, so that the excessive accumulation of static charge in the display panel can be further avoided, the interference effect of the static charge in the display panel on the electrical signal in the display panel is reduced, and the risk of abnormal display and chaotic display of the display panel is reduced, and the light-emitting element and circuit structure in the display panel can be further protected, the safety of the display panel is improved, the accuracy and stability of the displayed picture are improved, and the display effect and display quality of the display panel are improved.

[0055] As shown in FIG. 1 , in some feasible embodiments, the substrate 100 includes an organic substrate 110 and an inorganic substrate 120 stacked along a thickness direction, and the inorganic substrate 120 is located between the light-emitting layer 200 and the organic substrate 110 ; the conductive structure 400 passes through the inorganic substrate 120 , and the conductive structure 400 is in contact with the organic substrate 110 .

[0056] For example, in the direction from the substrate 100 to the encapsulation layer 300, a first organic substrate, a first barrier layer, a second organic substrate, a second barrier layer, a buffer layer, a gate insulating layer, and an interlayer dielectric layer may be sequentially stacked and arranged. The materials of the first organic substrate and the second organic substrate include organic materials, and the materials of the first barrier layer, the second barrier layer, the buffer layer, the gate insulating layer, and the interlayer dielectric layer include inorganic materials.

[0057] In the display panel provided by the embodiment of the present application, when the substrate 100 of the display panel includes an organic substrate 110 and an inorganic substrate 120, and the inorganic substrate 120 is located between the light-emitting layer 200 and the organic substrate 110, the conductive structure 400 penetrates the inorganic substrate 120, so that the conductive structure 400 can form direct contact with the organic substrate 110, and the conductive structure 400 can extract and release the static charge on the organic substrate 110, so as to prevent the static charge from migrating in the display panel and affecting other electronic devices in the display panel, thereby increasing the extraction amount of the static charge in the display panel, further accelerating the extraction speed of the static charge, making the extraction speed of the static charge in the display panel greater than the accumulation speed of the static charge, further suppressing the electrostatic interference of the display panel, reducing the risk of abnormal display and chaotic display of the display panel, and further protecting the light-emitting elements and circuit structures in the display panel, improving the safety of the display panel, improving the accuracy and stability of the displayed image, and improving the display effect and display quality of the display panel.

[0058] FIG2 is a schematic structural diagram of another display panel provided in an embodiment of the present application. As shown in FIG2, in some feasible embodiments, the conductive structure 400 includes a first conductive structure 410 and a second conductive structure 420, the first conductive structure 410 is electrically connected to the second conductive structure 420, the first conductive structure 410 is located on a side of the second conductive structure 420 away from the substrate 100, the first conductive structure 410 penetrates the encapsulation layer 300, the second conductive structure 420 penetrates the inorganic substrate 120, and the second conductive structure 420 is in contact with the organic substrate 110.

[0059] By way of example, the first conductive structure 410 and the second conductive structure 420 may be formed of different conductive materials.

[0060] It should be noted that the first conductive structure 410 and the second conductive structure 420 are formed in steps. In the case of forming the conductive structure 400 in an integrated manner, the conductive structure 400 needs to penetrate more film layers, so the thickness of the conductive structure 400 is relatively large, which will result in a deeper depth of the holes when punching holes in the film layers that need to be penetrated by the conductive structure 400 during the preparation process. If the drilling depth is too deep, the morphology of the inner wall of the through hole will be difficult to control, and the time and strength required for drilling will be relatively long, which may easily cause the display panel to break. In addition, when the conductive structure 400 is formed in an integrated manner in the through hole, due to the deep through hole, the directly formed conductive structure 400 may have a problem of poor integrity, resulting in poor uniformity of the conductive structure 400 in the through hole, or even a short circuit, which will affect the conductive performance of the conductive structure 400, resulting in the inability of static charge to be discharged through the conductive structure 400, causing static charge to migrate in the display panel, affecting the display effect of the display panel.

[0061] The display panel provided in the embodiment of the present application, by setting the conductive structure 400 including the first conductive structure 410 and the second conductive structure 420, can prepare the first conductive structure 410 and the second conductive structure 420 in steps during the preparation process of the display panel, thereby improving the integrity of the conductive structure 400 and improving the conductivity of the conductive structure 400, thereby increasing the amount of static charge extraction in the display panel, further accelerating the static charge extraction speed, so that the static charge extraction speed in the display panel is greater than the static charge accumulation speed, further suppressing the electrostatic interference of the display panel, reducing the risk of abnormal display and chaotic display of the display panel, and protecting the light-emitting elements and circuit structures in the display panel, improving the safety of the display panel, improving the accuracy and stability of the displayed picture, and improving the display effect and display quality of the display panel.

[0062] As shown in FIG. 2 , in some feasible implementations, the orthographic projection of the first conductive structure 410 toward the substrate 100 falls within the orthographic projection of the second conductive structure 420 toward the substrate 100 .

[0063] Exemplarily, an orthographic projection of the first conductive structure 410 toward the substrate 100 at least partially overlaps with an orthographic projection of the second conductive structure 420 toward the substrate 100 .

[0064] The display panel provided in the embodiment of the present application can further ensure that the first conductive structure 410 and the second conductive structure 420 can form an electrical connection, thereby improving the integrity of the conductive structure 400, improving the conductivity of the conductive structure 400, further suppressing electrostatic interference of the display panel, improving the safety of the display panel, and improving the display effect and display quality of the display panel.

[0065] As shown in FIG. 1 , in some feasible implementations, in the non-display area 102 , the encapsulation layer 300 includes a first inorganic encapsulation layer 310 and a second inorganic encapsulation layer 320 , and the first inorganic encapsulation layer 310 is located between the second inorganic encapsulation layer 320 and the substrate 100 .

[0066] Exemplarily, in the display area 101, the encapsulation layer 300 includes a first inorganic encapsulation layer 310, an organic encapsulation layer 330, and a second inorganic encapsulation layer 320 which are sequentially stacked and arranged along the thickness direction of the substrate 110. The flexibility of the encapsulation layer 300 can be improved by the organic encapsulation layer 330, and the air tightness of the encapsulation layer 300 can be improved by the first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 320, so as to avoid the organic encapsulation layer 330 and the light-emitting layer 200 from contacting with the external water and oxygen environment, thereby extending the service life of the display panel and further improving the safety, stability, and reliability of the display panel.

[0067] The display panel provided in the embodiment of the present application can prevent the light-emitting layer 200 inside the display panel from contacting the external water and oxygen environment by setting the encapsulation layer 300 including the first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 320, thereby extending the service life of the display panel and further improving the safety, stability and reliability of the display panel.

[0068] FIG3 is a schematic structural diagram of another display panel provided in an embodiment of the present application. As shown in FIG3, in some feasible implementations, the display panel further includes: a touch insulating layer 500, located on a side of the encapsulation layer 300 away from the substrate 100; wherein the first conductive structure 410 sequentially penetrates the touch insulating layer 500, the second inorganic encapsulation layer 320 and at least a portion of the first inorganic encapsulation layer 310, and the second conductive structure 420 sequentially penetrates at least a portion of the first inorganic encapsulation layer 310 and the inorganic substrate 120.

[0069] Illustratively, during the manufacturing process of the display panel, after the second conductive structure 420 is manufactured, the first inorganic encapsulation layer 310 is formed on a side of the second conductive structure 420 away from the substrate 100 .

[0070] The display panel provided in the embodiment of the present application can improve the touch performance of the display panel, improve the touch sensitivity of the display panel, and reduce the delay by setting the touch insulation layer 500, thereby further improving the display effect and display quality of the display panel.

[0071] As shown in FIG. 1 , in some feasible implementations, the display panel further includes: a dam structure 600 , the dam structure 600 is located in the non-display area 102 , and the encapsulation layer 300 is located on a side of the dam structure 600 away from the substrate 100 .

[0072] The display panel provided in the embodiment of the present application can prevent the outflow of liquid packaging material during the organic packaging process of the display panel by setting the cofferdam structure 600, and can also prevent the organic packaging layer 330 from contacting the external water and oxygen environment through the side of the display panel, thereby improving the packaging quality of the display panel, improving the safety of the display panel, and extending the service life of the display panel, and further improving the display effect and display quality of the display panel, and improving the reliability and stability of the display panel.

[0073] As shown in FIG. 1 , in some feasible implementations, the orthographic projection of the conductive structure 400 toward the substrate 100 does not overlap with the orthographic projection of the cofferdam structure 600 toward the substrate 100 .

[0074] The display panel provided in the embodiment of the present application can make it unnecessary for the conductive structure 400 to penetrate the cofferdam structure 600, thereby reducing the thickness of the conductive structure 400, reducing the difficulty of preparing the conductive structure 400, and improving the preparation quality of the conductive structure 400, thereby improving the integrity of the conductive structure 400, and improving the conductivity of the conductive structure 400, thereby increasing the amount of static charge extracted from the display panel, and further accelerating the speed of extracting the static charge, so that the speed of extracting the static charge from the display panel is greater than the speed of accumulating the static charge, further suppressing the electrostatic interference of the display panel, reducing the risk of abnormal and chaotic display of the display panel, and protecting the light-emitting elements and circuit structures in the display panel, improving the safety of the display panel, improving the accuracy and stability of the displayed image, and improving the display effect and display quality of the display panel.

[0075] As shown in FIG. 1 , in some feasible implementations, the conductive structure 400 is located on a side of the cofferdam structure 600 away from the light-emitting layer 200 .

[0076] For example, when there are at least two cofferdam structures 600 , there may be at least two conductive structures 400 , wherein the conductive structure 400 may be located between adjacent cofferdam structures 600 or on a side of the cofferdam structure 600 farthest from the light-emitting layer 200 away from the light-emitting layer 200 .

[0077] The display panel provided in the embodiment of the present application can increase the distance between the cofferdam structure 600 and the light-emitting layer 200, thereby further reducing the risk of static charge entering the light-emitting layer 200, improving the accuracy of the driving effect of the light-emitting layer 200, further improving the accuracy and stability of the displayed image, and protecting the light-emitting elements in the light-emitting layer 200, thereby improving the safety of the display panel, extending the service life of the display panel, and improving the display effect and display quality of the display panel.

[0078] As shown in FIG. 3 , in some feasible implementations, the display panel further includes: a touch conductive layer 700 located on a side of the encapsulation layer 300 away from the substrate 100 , and the touch conductive layer 700 is located in the display area 101 ; wherein the touch conductive layer 700 is insulated from the conductive structure 400 .

[0079] The display panel provided in the embodiment of the present application can have a touch function by setting a touch conductive layer 700, and can realize on-screen operation without external devices. At the same time, by insulating the touch conductive layer 700 from the conductive structure 400, it can avoid the static charge on the conductive structure 400 from interfering with the transmission of the touch signal, thereby improving the touch accuracy of the display panel.

[0080] As shown in FIG. 3 , in some feasible implementations, the touch conductive layer 700 and the conductive structure 400 are formed simultaneously.

[0081] Exemplarily, the material of the touch conductive layer 700 may include a metal material. The touch conductive layer 700 and the conductive structure 400 may be simultaneously prepared by a metal film process. During the preparation of the touch conductive layer 700 and the conductive structure 400, since there is a height difference between the surface of the cofferdam structure 600 away from the substrate 100 and the surface of the packaging layer 300 around the cofferdam structure 600 away from the substrate 100, the metal film will automatically break at the edge of the cofferdam structure 600, thereby obtaining an insulated touch conductive layer 700 and the conductive structure 400, so as to achieve the synchronous preparation of the touch conductive layer 700 and the conductive structure 400.

[0082] The display panel provided in the embodiment of the present application can save process flow, simplify preparation steps, and improve preparation efficiency by simultaneously preparing the touch conductive layer 700 and the conductive structure 400, thereby further improving the preparation quality of the display panel.

[0083] As shown in FIG. 1 , in some feasible embodiments, the display panel further includes: a driving circuit layer 800, which is located in the non-display area 102, the driving circuit layer 800 is electrically connected to the light-emitting layer 200, and the driving circuit layer 800 is used to drive the light-emitting layer 200 to light up; in the direction from the display area 101 to the non-display area 102, the driving circuit layer 800 is located between the conductive structure 400 and the light-emitting layer 200.

[0084] Fig. 4 is a schematic top view of a display panel provided by an embodiment of the present application. As shown in Fig. 4 , in the direction from the display area 101 to the non-display area 102 , the driving circuit layer 800 is located between the conductive structure 400 and the light emitting layer 200 .

[0085] Exemplarily, the driving circuit layer 800 may include a VSR (Voltage Source Converter) circuit for outputting a scan signal.

[0086] It should be noted that static charges usually migrate between organic film layers in the display panel along the cutting lines, and the cutting lines are usually located on a side of the driving circuit layer 800 away from the light emitting layer 200 .

[0087] The display panel provided in the embodiment of the present application, by setting the conductive structure 400 on the side of the driving circuit layer 800 away from the light-emitting layer 200, can guide the static charge through the conductive structure 400 during the migration of the static charge from the cutting path in the non-display area 102 to the display area 101, and can further prevent the static charge from entering the driving circuit layer 800 and affecting the signal transmission on the driving circuit in the driving circuit layer 800, thereby reducing the interference of the static charge on the electrical signal in the display panel, and further improving the transmission quality of the electrical signal in the display panel, reducing the risk of abnormal display and chaotic display of the display panel, and further protecting the light-emitting elements and circuit structure in the display panel, improving the safety of the display panel, improving the accuracy and stability of the displayed picture, and improving the display effect and display quality of the display panel.

[0088] As shown in FIG. 5 , a second aspect of an embodiment of the present application provides a display device, comprising: a display panel 1000 according to any one of the above-mentioned first aspects.

[0089] The display device provided by the embodiment of the present application is provided with a conductive structure 400 penetrating the encapsulation layer 300, so that one end of the conductive structure 400 is used to contact the organic substrate 110 in the substrate 100, and the other end of the conductive structure 400 is used to be grounded, so that the conductive structure 400 can extract and release the static charge of the organic substrate 110. Therefore, the extraction speed of the static charge can be accelerated, and under the action of the external electric field, the extraction speed of the static charge in the display panel 1000 can be made greater than the accumulation speed of the static charge, so that the excessive accumulation of static charge in the display panel 1000 can be further avoided, the interference effect of the static charge in the display panel 1000 on the electrical signal in the display panel 1000 is reduced, and the risk of abnormal display and chaotic display of the display panel 1000 is reduced. Further, the light-emitting element and circuit structure in the display panel 1000 can be protected, the safety of the display panel 1000 is improved, the accuracy and stability of the displayed picture are improved, and the display effect and display quality of the display panel 1000 are improved.
