[0042] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0043] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0044] In related technologies, a sealing layer is installed inside the display panel to isolate water and oxygen, preventing moisture from penetrating the light-emitting structure or signal lines beneath the sealing layer and reducing the risk of malfunctions. However, the applicant's research has found that some signal lines in the display panel are located outside the boundary of the sealing layer. These signal lines are not protected by the sealing layer, making them susceptible to water and oxygen intrusion, especially when cracks appear in the film layer above the signal lines, which easily leads to water and oxygen corrosion. Furthermore, the voltage output of these signal lines is not uniform, meaning there is a voltage difference between adjacent signal lines. Under the combined effect of this voltage difference and water and oxygen, the signal lines are prone to electrochemical corrosion, resulting in display defects.

[0045] To solve the above problems, firstly, please refer to [the relevant information]. Figures 1 to 4The embodiment of the present application provides a display panel, which comprises a substrate 1, an encapsulation layer 2, a first signal line 3, a second signal line 4 and an isolation signal line 5, the encapsulation layer 2 is located on one side of the substrate 1, the first signal line 3 is arranged on one side of the substrate 1 and at least partially located outside the boundary of the encapsulation layer 2, the first signal line 3 is used for transmitting a first voltage signal, the second signal line 4 is arranged on one side of the substrate 1 and at least partially located outside the boundary of the encapsulation layer 2, the second signal line 4 is used for transmitting a second voltage signal, and there is a voltage difference between the first voltage signal and the second voltage signal. The isolation signal line 5 is at least partially located between the first signal line 3 and the second signal line 4, and the isolation signal line 5 is configured to be able to interfere with the electric field between the first signal line 3 and the second signal line 4.

[0046] The encapsulation layer 2 is located on one side of the substrate 1, and the encapsulation layer 2 is used for reducing the risk of water and oxygen invasion on part of the structure in the display panel. Exemplarily, the display panel has an encapsulation area A1 and a frame area A2 located on the peripheral side of the encapsulation area A1, the position corresponding to the encapsulation layer 2 is the position of the encapsulation area A1, and a light emitting device layer 6 is further arranged in the display panel, the light emitting device layer 6 comprises a plurality of light emitting units of different colors, and the plurality of light emitting units are located in the encapsulation area A1, and the encapsulation layer 2 can protect the light emitting unit.

[0047] The first signal line 3, the second signal line 4 and the encapsulation layer 2 are located on the same side of the substrate 1, and the specific film layer relationship of the first signal line 3 and the second signal line 4 relative to the encapsulation layer 2 is not limited in the embodiment of the present application. In other words, the first signal line 3 and the second signal line 4 can be located on the side of the encapsulation layer 2 away from the substrate 1, or can be located on the side of the encapsulation layer 2 close to the substrate 1. Exemplarily, the display panel comprises a planarization layer 8 arranged on one side of the substrate 1, the first signal line 3 and the second signal line 4 are located on the side of the planarization layer 8 away from the substrate 1, and the encapsulation layer 2 is located on the side of the first signal line 3 and the second signal line 4 away from the substrate 1.

[0048] The first signal line 3 and the second signal line 4 are located outside the boundary of the encapsulation layer 2, that is, the first signal line 3 and the second signal line 4 are located in the frame area A2, and the encapsulation layer 2 cannot protect the first signal line 3 and the second signal line 4, and the first signal line 3 and the second signal line 4 are at risk of water and oxygen invasion. At the same time, due to the voltage difference between the first voltage signal output by the first signal line 3 and the second voltage signal output by the second signal line 4, under the joint action of the voltage difference and water and oxygen, the transmission of charged particles is easy to form, and therefore the risk of electrochemical corrosion is easy to occur.

[0049] Specifically, due to the pressure difference between the first signal line 3 and the second signal line 4, the electric fields generated by the first signal line 3 and the second signal line 4 are not the same, and the first signal line 3 and the second signal line 4 do not lose or gain electrons in the same way. Generally, one of the first signal line 3 and the second signal line 4 gains electrons, and the other loses electrons. Further, under the influence of water and oxygen intrusion, at least one of the first signal line 3 and the second signal line 4 is more likely to be at risk of electrochemical corrosion, resulting in display abnormalities of the display panel.

[0050] The application does not limit the pressure difference between the first signal line 3 and the second signal line 4. Meanwhile, the application does not limit the relative position between the first signal line 3 and the second signal line 4, as long as the first signal line 3 and the second signal line 4 are located outside the boundary of the packaging layer 2.

[0051] In order to reduce the risk of electrochemical corrosion of the first signal line 3 and the second signal line 4, the application adds an isolation signal line 5 between the first signal line 3 and the second signal line 4, at least part of the isolation signal line 5 is located between the first signal line 3 and the second signal line 4. The isolation signal line 5 is a conductive structure, which can be a signal line with a certain current, or a conductor without potential. The existence of the isolation signal line 5 can interfere with or even shield the electric field between the first signal line 3 and the second signal line 4, thereby changing the gain or loss of electrons of the first signal line 3 and the second signal line 4, and further reducing the risk of electrochemical corrosion of the first signal line 3 and the second signal line 4, and improving the display reliability of the display panel.

[0052] The application can weaken the risk of corrosion between the first signal line 3 and the second signal line 4 by setting the isolation signal line 5 between the first signal line 3 and the second signal line 4, and using the isolation signal line 5 to interfere with the electric field between the first signal line 3 and the second signal line 4, thereby improving the display reliability and service life of the display panel.

[0053] It should be noted that the application does not limit the material of the isolation signal line 5. The isolation signal line 5 can be made of the same material as the first signal line 3 or the second signal line 4, or can be made of a different material.

[0054] In some embodiments, referring to Figure 3 The display panel further includes an insulating layer 7, and the insulating layer 7 at least partially fills between the first signal line 3 and the second signal line 4.

[0055] The insulating layer 7 includes an insulating material used to insulate and separate the first signal line 3 from the second signal line 4, thereby reducing the risk of signal crosstalk caused by mutual conduction between the first signal line 3 and the second signal line 4. Optionally, a portion of the insulating layer 7 is filled between the first signal line 3 and the isolation signal line 5, and a portion is filled between the second signal line 4 and the isolation signal line 5. The insulating layer 7 can achieve insulation between any two of the first signal line 3, the second signal line 4, and the isolation signal line 5.

[0056] The isolation signal line 5 is used to influence or even shield the electric field between the first signal line 3 and the second signal line 4, but it cannot prevent the first signal line 3 and the second signal line 4 from conducting. The insulating material in the insulating layer 7 can insulate the first signal line 3 and the second signal line 4, but it cannot affect the electric field generated by the first signal line 3 and the second signal line 4. Therefore, this embodiment of the application further reduces the mutual influence between the first signal line 3 and the second signal line 4 and reduces the risk of electrochemical corrosion by simultaneously providing the insulating layer 7 and the isolation signal line 5 between the first signal line 3 and the second signal line 4. Optionally, the insulating layer 7 includes an organic material.

[0057] In some implementations, such as Figure 3 As shown, the first signal line 3 and the second signal line 4 are disposed in the same layer, and the insulating layer 7 includes a first portion 71 filled between the first signal line 3 and the second signal line 4 and a second portion 72 covering the first signal line 3 and the second signal line 4.

[0058] The insulating layer 7 includes a first portion 71 and a second portion 72, which are integrally formed. Exemplarily, the first portion 71 consists of two parts: one part is located between the first signal line 3 and the isolation signal line 5, and the other part is located between the second signal line 4 and the isolation signal line 5. The second portion 72 is located on the side of the first signal line 3 facing away from the substrate 1. The second portion 72 can simultaneously cover the first signal line 3, the isolation signal line 5, and the second signal line 4, thereby improving the insulation effect on the three signal lines.

[0059] In some embodiments, such as Figure 5 As shown, the first signal line 3 and the second signal line 4 are disposed in different layers, and the insulating layer 7 is sandwiched between the first signal line 3 and the second signal line 4.

[0060] The first signal line 3 and the second signal line 4 are located on different layers, and the orthographic projection of the first signal line 3 onto the substrate 1 and the orthographic projection of the second signal line 4 onto the substrate 1 at least partially overlap. An insulating layer 7 is sandwiched between the first signal line 3 and the second signal line 4. Exemplarily, a portion of the structure in the insulating layer 7 is sandwiched between the first signal line 3 and the isolation signal line 5, and a portion of the structure is sandwiched between the second signal line 4 and the isolation signal line 5.

[0061] In some embodiments, the first signal line 3 and the second signal line 4 are arranged in the same layer, and the projection of the isolation signal line 5 on the substrate 1 is located between the projection of the first signal line 3 on the substrate 1 and the projection of the second signal line 4 on the substrate 1.

[0062] The isolation signal line 5 can be arranged in the same layer as the first signal line 3 or in a different layer from the first signal line 3, and the embodiments of the present application do not limit this, as long as the projection of the isolation signal line 5 on the substrate 1 can be at least partially located between the projection of the first signal line 3 on the substrate 1 and the projection of the second signal line 4 on the substrate 1. In other words, in the direction parallel to the plane where the substrate 1 is located, the isolation signal line 5 is at least partially located between the first signal line 3 and the second signal line 4.

[0063] In some embodiments, as shown in FIG. 1, the isolation signal line 5 is arranged in the same layer as the first signal line 3. Figure 3

[0064] The first signal line 3, the isolation signal line 5, and the second signal line 4 are all located in the same film layer, and the isolation signal line 5 is located between the first signal line 3 and the second signal line 4. This design enables the isolation signal line 5 to have a stronger interference effect on the electric field between the first signal line 3 and the second signal line 4, further reducing the risk of electrochemical corrosion. Optionally, the thickness of the isolation signal line 5 is greater than the thickness of at least one of the first signal line 3 and the second signal line 4, so as to further improve the interference effect of the isolation signal line 5 on the electric field.

[0065] In some embodiments, the first signal line 3 and the second signal line 4 are both power supply lines.

[0066] The first signal line 3 and the second signal line 4 are both used to drive the display panel to realize the light-emitting function, wherein one of the first signal line 3 and the second signal line 4 is a positive power supply line for providing a positive voltage signal, and the other is a negative power supply line for providing a negative voltage signal. Thus, there will be a pressure difference between the first signal line 3 and the second signal line 4, which is prone to electrochemical corrosion under the influence of water and oxygen and other factors. Optionally, the pressure difference between the first signal line 3 and the second signal line 4 is not less than 5V. On this basis, the embodiments of the present application provide the isolation signal line 5 for interfering with or even shielding the electric field between the first signal line 3 and the second signal line 4, thereby reducing the risk of electrochemical corrosion.

[0067] In some embodiments, the material of at least one of the first signal line 3 and the second signal line 4 is the same as the material of the isolation signal line 5.

[0068] ​Since the isolation signal line 5 is disposed on the same layer as the first signal line 3 and the second signal line 4, and the material of the isolation signal line 5 is the same as the material of the first signal line 3 or the second signal line 4, at least one of the first signal line 3 and the second signal line 4 can be fabricated simultaneously with the isolation signal line 5 using the same mask during the display panel manufacturing process, thereby simplifying the display panel manufacturing process and improving production efficiency.

[0069] In some embodiments, the material of the isolation signal line 5 includes at least one of molybdenum, titanium, and aluminum. Exemplarily, the isolation signal line 5 may be a three-layer metal structure composed of titanium / aluminum / titanium.

[0070] In some embodiments, such as Figure 5 As shown, the first signal line 3 and the second signal line 4 are disposed in different layers, and the orthographic projection of the isolation signal line 5 on the substrate 1 covers the orthographic projection of at least one of the first signal line 3 and the second signal line 4 on the substrate 1.

[0071] In the thickness direction of the display panel, an isolation signal line 5 is sandwiched between the first signal line 3 and the second signal line 4. Simultaneously, the orthogonal projection of the isolation signal line 5 onto the substrate 1 covers the orthogonal projection of at least one of the first signal line 3 and the second signal line 4 onto the substrate 1. For example, the orthogonal projection of the isolation signal line 5 onto the substrate 1 covers the orthogonal projection of the first signal line 3 onto the substrate 1. This design can improve the interference effect of the isolation signal line 5 on the electric field generated by the first signal line 3, thereby reducing the influence of the first signal line 3 on the second signal line 4 and improving the reliability of the display panel.

[0072] In some alternative embodiments, the orthographic projection of the isolation signal line 5 onto the substrate 1 simultaneously covers the orthographic projections of the first signal line 3 and the second signal line 4 onto the substrate 1. This can simultaneously improve the interference effect of the isolation signal line 5 on the electric fields generated by the first signal line 3 and the second signal line 4, further reducing the risk of chemical corrosion.

[0073] In some embodiments, such as Figure 2 As shown, the extension direction of the isolation signal line 5 is parallel to the extension direction of at least one of the first signal line 3 and the second signal line 4.

[0074] The first signal line 3 and the second signal line 4 can be extended in a straight line or in a curved form, and this application embodiment does not limit this. The phrase "the extension direction of the isolation signal line 5 is parallel to the extension direction of at least one of the first signal line 3 and the second signal line 4" mentioned in this application embodiment means that the extension direction of the isolation signal line 5 at a specific position is the same as the extension direction at the corresponding position on the first signal line 3 or the second signal line 4, that is, the isolation signal line 5 can also be extended in a curved form.

[0075] Since the extending direction of the isolation signal line 5 is parallel to the extending direction of at least one of the first signal line 3 and the second signal line 4, the isolation signal line 5 can better play the electric field interference effect on at least one of the first signal line 3 and the second signal line 4 in the extending direction of the isolation signal line 5. It should be noted that in the embodiment of the present application, the first signal line 3 can be arranged in the same layer as the second signal line 4, or the first signal line 3 can be arranged in different layers from the second signal line 4.

[0076] In some embodiments, the extending direction of the first signal line 3 is parallel to the extending direction of the second signal line 4, that is, the first signal line 3, the second signal line 4 and the isolation signal line 5 extend parallel to each other.

[0077] This design enables the isolation signal line 5 to simultaneously enhance its electric field interference effect on the first signal line 3 and the second signal line 4 in its own extending direction, further reducing the risk of electrochemical corrosion of the display panel.

[0078] In some embodiments, the number of isolation signal lines 5 is multiple segments, and the multiple segments of the isolation signal line 5 are arranged at intervals in the extending direction of the first signal line 3 or the second signal line 4.

[0079] In the embodiment of the present application, by arranging the isolation signal line 5 in a multi-segment structure and arranging the multiple segments of the isolation signal line 5 at intervals, the electric field at the first signal line 3 or the second signal line 4 at a specific position is interfered and shielded, thereby improving the reliability of the display panel while reducing the material consumption of the isolation signal line 5.

[0080] In some embodiments, the isolation signal line 5 is used to transmit a pulse signal.

[0081] The pulse signal is a discrete signal, and the pulse signal is a signal continuously emitted at a certain voltage amplitude and a certain time interval. Compared with other signal forms, the pulse signal has a stronger electromagnetic interference effect, that is, it can produce a stronger interference effect on the electric field between the first signal line 3 and the second signal line 4, thereby further reducing the risk of electrochemical corrosion. The voltage of the pulse signal is not limited in the embodiment of the present application, and the voltage of the pulse signal can be greater than, less than or equal to the first voltage signal of the first signal line 3 and the second voltage signal of the second signal line 4.

[0082] In some embodiments, the isolation signal line 5 is used to transmit a direct current signal, and the signal voltage of the isolation signal line 5 is between the first signal line 3 and the second signal line 4.

[0083] In the embodiments of the present application, the isolation signal line 5 is mainly used to reduce the voltage variation gradient between the first signal line 3 and the second signal line 4, thereby playing a role of interfering with the electric field between the first signal line 3 and the second signal line 4. Specifically, for the case where the isolation signal line 5 is not arranged, the intensity of the electric field between the first signal line 3 and the second signal line 4 is greater than the intensity of the electric field between the isolation signal line 5 and the first signal line 3 and the electric field between the isolation signal line 5 and the second signal line 4. Therefore, the arrangement of the isolation signal line 5 can reduce the electric field intensity to which the first signal line 3 and the second signal line 4 are subjected, thereby reducing the risk of electrochemical corrosion of the first signal line 3 and the second signal line 4.

[0084] In some embodiments, referring to Figure 3 and Figure 5 , the distance between at least one of the first signal line 3 and the second signal line 4 and the isolation signal line 5 is L, and L satisfies: 10 μm≤L≤30 μm.

[0085] The first signal line 3 and the second signal line 4 are arranged apart from the isolation signal line 5. If the distance between one of the first signal line 3 and the second signal line 4 and the isolation signal line 5 is too small, the voltage signal in the isolation signal line 5 is easy to interfere with the first voltage signal in the first signal line 3 or the second voltage signal in the second signal line 4, resulting in problems in signal transmission in the display panel, thereby affecting the display effect.

[0086] If the distance between one of the first signal line 3 and the second signal line 4 and the isolation signal line 5 is too large, the isolation signal line 5 is difficult to interfere with the electric field corresponding to the first signal line 3 or the second signal line 4, and the display panel is easy to have the risk of electrochemical corrosion, resulting in the problem of display abnormality.

[0087] Therefore, the embodiments of the present application set the distance L between 10 μm and 30 μm, thereby reducing the electrochemical corrosion of the display panel, reducing the influence of the isolation signal line 5 on the first voltage signal or the second voltage signal, and improving the reliability of the display panel. Optionally, L is one of 10 μm, 15 μm, 20 μm, 25 μm and 30 μm.

[0088] In a second aspect, referring to Figure 6 , the embodiments of the present application provide a display device comprising the display panel in any of the preceding embodiments.
