[0023] See also Figure 1 , Figure 2 and Figure 3 The present application provides a display panel 10, which includes a display area 11 and a frame area 12 located outside the display area 11. The display panel 10 includes a substrate 20 and a functional layer 30. The functional layer 30 is arranged on one side of the substrate 20, including a first wiring 31 located in the frame area 12 and arranged in the same layer, and a first electrostatic lead-out portion 32 electrically connected to the first wiring 31. The first wiring 31 is arranged around the display area 11, and the first electrostatic lead-out portion 32 is located on a side of the first wiring 31 away from the display area 11, wherein the first electrostatic lead-out portion 32 is connected to the first wiring 31, and both ends are bent and extended toward the edge of the display panel 10.

[0024] Specifically, the substrate 20 plays a supporting role in the display panel 10, and it can be a flexible substrate or a rigid substrate. When the substrate 20 is a flexible substrate, its material can be polyimide (PI), and when the substrate 20 is a rigid substrate, its material can be glass or metal. The present application does not limit the structure of the substrate 20.

[0025] At the same time, the display panel 10 includes a display area 11 and a frame area 12. The display area 11 is mainly used to realize the display function of the display panel 10, and the frame area 12 is used to arrange wiring to support the display function of the display area 11. The functional layer 30 refers to a functional film layer in the display panel 10, for example, it can be an array layer, a light-emitting layer, a touch layer or a packaging layer. A first wiring 31 is set in the functional layer 30. In order not to affect the function of the display area 11, the first wiring 31 is located at the periphery of the display area 11. In one embodiment, the first wiring 31 is grounded to release static electricity in the display panel 10 and improve the anti-static ability of the display panel 10. At the same time, a first electrostatic lead-out portion 32 is also provided to be electrically connected to the first wiring 31. At this time, the first electrostatic lead-out portion 32 is equivalent to the "antenna" connected to the first wiring 31, which can be used to attract the static electricity accumulated on the side of the display panel 10 (usually, most of the static electricity on the display panel 10 is accumulated on the side of the display panel 10. For example, during the copper rod test or the back pressure test, the static electricity accumulated on the side of the display panel 10 is significantly increased, and the accumulated static electricity easily induces the change of the characteristics of the display panel 10 and causes the display panel 10 to turn green). Then, the first electrostatic lead-out portion 32 transfers the static electricity to the first wiring 31, and finally guides the static electricity accumulated on the side of the display panel 10 to the ground, further avoiding the damage of the display panel 10 to the static electricity. At the same time, the two ends of the first electrostatic lead-out portion 32 are bent and extended toward the edge of the display panel 10. Compared with the straight structure of the first electrostatic lead-out portion 32, the present application can extend the static electricity path, improve the ability of the first side wiring 31 and the first electrostatic lead-out portion 32 to withstand static electricity, and further improve the static electricity release effect.

[0026] Please continue reading Figure 3 , the orthographic projection of the first electrostatic lead-out portion 32 on the substrate 20 is arc-shaped. The first electrostatic lead-out portion 32 is designed in an arc shape, which further extends the electrostatic path and improves the reliability of the display panel 10. Of course, in other embodiments, the first electrostatic lead-out portion 32 can also be designed in a zigzag shape or a wavy shape, which is not limited here, as long as the middle of the first electrostatic lead-out portion 32 is electrically connected to the first wiring 31, and both ends are bent and extended toward the edge of the display panel 10.

[0027] In one embodiment, continue to refer to Figure 3 The middle part of the first electrostatic lead-out portion 32 is connected to the first wiring 31 .

Specifically, the first wiring 31 and the first static electricity lead-out portion 32 are made of the same material, which saves process steps and improves manufacturing efficiency.

[0029] In one embodiment, the first wiring 31 and the first electrostatic lead-out portion 32 are integrally formed, so that the first wiring 31 and the first electrostatic lead-out portion 32 can be prepared by the same process, thereby improving the preparation efficiency and ensuring the connection strength between the first wiring 31 and the first electrostatic lead-out portion 32.

[0030] Please continue reading Figure 3 The functional layer 30 further includes a connection block 33 disposed in the same layer as the first wiring 31, the connection block 33 is located between the first wiring 31 and the first electrostatic lead-out portion 32, and electrically connects the first wiring 31 and the first electrostatic lead-out portion 32. Specifically, the arrangement of the connection block 33 increases the contact area between the first wiring 31 and the first electrostatic lead-out portion 32, ensures the electrostatic transmission effect, and can also improve the ability of the first wiring 31 and the first electrostatic lead-out portion 32 to withstand static electricity.

[0031] In one embodiment, if Figure 3 As shown, there are two connection blocks 33, and the two connection blocks 33 are located on both sides of the connection 34 between the first wiring 31 and the first electrostatic lead-out portion 32. Specifically, there are two connection blocks 33 between the same first electrostatic lead-out portion 32 and the first wiring 31, and the two connection blocks 33 are symmetrically arranged relative to the connection 34 between the first wiring 31 and the first electrostatic lead-out portion 32, thereby ensuring the electrostatic transmission effect. Of course, in other embodiments, only one connection block 33 may be provided.

[0032] In one embodiment, the connection block 33, the first electrostatic lead-out portion 32 and the first wiring 31 are integrally formed. Specifically, the connection block 33, the first electrostatic lead-out portion 32 and the first wiring 31 are simultaneously manufactured by the same manufacturing process, which is conducive to improving the manufacturing efficiency and ensuring the connection strength among the three.

[0033] In one embodiment, there are multiple first electrostatic lead-out portions 32, and the multiple first electrostatic lead-out portions 32 are arranged at intervals and are all electrically connected to the first wiring 31. Specifically, multiple first electrostatic lead-out portions 32 are arranged in the display panel 10, which can better attract static electricity gathered on the side of the display panel 10 and prevent static electricity from damaging the display panel 10. The multiple first electrostatic lead-out portions 32 can be arranged in an equidistant manner or in an unequal distance manner. The specific arrangement is flexible and can be arranged as needed.

[0034] In one embodiment, the plurality of first electrostatic derivation portions 32 are arranged at equal intervals. Specifically, the equal interval arrangement facilitates the arrangement of the plurality of first electrostatic derivation portions 32, facilitates the design, and ensures the electrostatic attraction effect.

[0035] In one embodiment, the structures of the plurality of first electrostatic decoupling portions 32 are the same, which facilitates the preparation of the first electrostatic decoupling portions 32 , reduces the preparation difficulty, and ensures the preparation efficiency.

[0036] See also Figure 4 , the functional layer 30 is a touch layer, and the functional layer 30 further includes a first touch electrode 35, which is located in the display area 11 and is arranged in the same layer as the first wiring 31. Specifically, when the functional layer 30 is a touch layer, it has the effect of display control according to the user's touch, and at this time, the touch effect is mainly achieved by the first touch electrode 35.

[0037] In one embodiment, the first touch electrodes 35 and the first wirings 31 are made of the same material. Specifically, the first touch electrodes 35 and the first wirings 31 can be obtained by patterning the same conductive layer, thereby improving manufacturing efficiency.

[0038] See also Figure 5 The functional layer 30 further includes a second routing line 40 and an insulating sublayer 50, wherein the second routing line 40 is located in the border area 12 and is arranged in a different layer from the first routing line 31; the insulating sublayer 50 is formed between the first routing line 31 and the second routing line 40, wherein the first routing line 31 is electrically connected to the second routing line 40 through at least one via 51 on the insulating sublayer 50.

[0039] Specifically, a second wiring 40 is further provided in the functional layer 30, and the second wiring 40 is located in the frame area 12 to avoid affecting the normal display function of the display area 11. At the same time, the first wiring 31 is electrically connected to the second wiring 40 through one or more vias 51 on the insulating sublayer 50, so as to realize the parallel connection between the first wiring 31 and the second wiring 40, reduce the resistance of the electrostatic transmission, and improve the electrostatic transmission capability. Among them, the second wiring 40 can be indirectly grounded through the first wiring 31, or directly grounded.

[0041] In one embodiment, the orthographic projection of the first wiring 31 on the substrate 20 at least partially overlaps with the orthographic projection of the second wiring 40 on the substrate 20. Specifically, the orthographic projection of the first wiring 31 on the substrate 20 and the orthographic projection of the second wiring 40 on the substrate 20 may partially overlap or completely overlap, which is conducive to reducing the frame of the display panel 10 and realizing a narrow frame design.

[0042] See also Figure 6The functional layer 30 further includes a second electrostatic lead-out portion 42, which is located in the frame area 12 and is arranged in the same layer as the second wiring 40. The second electrostatic lead-out portion 42 is located on the side of the second wiring 40 away from the display area 11 and is electrically connected to the second wiring 40. Specifically, the second wiring 40 is arranged around the display area 11, and the second electrostatic lead-out portion 42 can transfer the static electricity accumulated on the side of the display panel 10 to the second wiring 40, further preventing the static electricity from damaging the display panel 10. In other words, the function of the second electrostatic lead-out portion 42 is the same as that of the first electrostatic lead-out portion 32.

[0043] In one embodiment, the second static electricity lead-out portion 42 is connected to the second wiring 40, and both ends are bent and extended toward the edge of the display panel 10. Specifically, similar to the configuration of the first static electricity lead-out portion 32, this configuration can extend the static electricity path and improve the static electricity release effect.

[0044] In one embodiment, the middle of the second static electricity lead-out portion 42 is electrically connected to the second wiring 40. Of course, in other embodiments, the second static electricity lead-out portion 42 may also be connected to the second wiring 40 at one end and connected to the edge of the display panel 10 at the other end, in which case the second static electricity lead-out portion 42 is a linear structure.

[0045] In one embodiment, the orthographic projection of the second electrostatic derivation portion 42 on the substrate 20 at least partially overlaps with the orthographic projection of the first electrostatic derivation portion 32 on the substrate 20. Specifically, the orthographic projections of the second electrostatic derivation portion 42 and the first electrostatic derivation portion 32 on the substrate 20 completely overlap or partially overlap, which ensures the electrostatic derivation effect while saving the area of ​​the frame occupied, thereby realizing a narrow frame of the display panel 10.

[0046] In one embodiment, the second routing 40 and the second electrostatic lead-out portion 42 are made of the same material, so that the second routing 40 and the second electrostatic lead-out portion 42 can be prepared using the same material during the preparation process, and the second routing 40 and the second electrostatic lead-out portion 42 can be prepared in the same process, which can save process steps and improve preparation efficiency.

[0047] In one embodiment, the second wiring 40 and the second electrostatic lead-out portion 42 are integrally formed, so that the second wiring 40 and the second electrostatic lead-out portion 42 can be prepared by the same process, thereby improving the preparation efficiency and ensuring the connection strength between the second wiring 40 and the second electrostatic lead-out portion 42.

[0048] In one embodiment, the first wiring 31 and the second wiring 40 have the same structure, which is convenient for design and is beneficial for application in the display panel 10 .

[0049] In one embodiment, the first static electricity lead-out portion 32 has the same structure as the second static electricity lead-out portion 42. Specifically, the first static electricity lead-out portion 32 and the second static electricity lead-out portion 42 have the same structure, which is convenient for design and is beneficial for application in the display panel 10.

[0050] In one embodiment, when the functional layer 30 is a touch layer, the functional layer 30 further includes a first touch electrode 35 and a second touch electrode (not shown), wherein the first touch electrode 35 is located in the display area 11 and is arranged in the same layer as the first wiring 31; the second touch electrode is located in the display area 11 and is arranged in the same layer as the second wiring 40. Specifically, when the functional layer 30 is a touch layer, the first touch electrode 35 and the second touch electrode are arranged in different layers, and the first wiring 31 and the second wiring 40 are respectively designed in the layers where the first touch electrode 35 and the second touch electrode are located, so as to realize anti-static protection for the first touch electrode 35 and the second touch electrode.

[0051] In one embodiment, the first touch electrodes 35 and the first traces 31 are made of the same material. Specifically, the first touch electrodes 35 and the first traces 31 are obtained by patterning the same conductive layer, thereby improving manufacturing efficiency.

[0052] In one embodiment, the second touch electrodes are made of the same material as the second wiring 40. Specifically, the second touch electrodes and the second wiring 40 are obtained by patterning the same conductive layer, thereby improving manufacturing efficiency.

[0053] Please continue reading Figure 3 , at least part of the first wiring 31 is in a grid structure. Specifically, the design of the grid structure is conducive to the rapid release of static electricity, further improving the reliability of the display panel 10. Even in the air discharge test, static electricity will not damage the metal components in the display panel 10.

[0054] In one embodiment, the first routing line 31 includes a first sub-routing line 37, a second sub-routing line 38 and a connecting sub-routing line 39, wherein the first sub-routing line 37 is arranged around the display area 11; the second sub-routing line 38 is arranged around the first sub-routing line 37 and is arranged at intervals from the first sub-routing line 37; the connecting sub-routing line 39 is in a grid structure, arranged between the first sub-routing line 37 and the second sub-routing line 38, and electrically connects the first sub-routing line 37 and the second sub-routing line 38. Specifically, the design of the grid structure of the connecting sub-routing line 39 ensures the electrostatic transmission effect, and the connecting sub-routing line 39 is arranged between the first sub-routing line 37 and the second sub-routing line 38, so as to achieve the structural stability of the first routing line 31. Even if any one of the first sub-routing line 37, the second sub-routing line 38 and the connecting sub-routing line 39 is damaged, the electrostatic transmission path still exists, and the electrostatic extraction effect can be ensured.

[0055] In one embodiment, the first sub-routing 37, the second sub-routing 38 and the connecting sub-routing 39 are made of the same material. Specifically, using the same material to prepare the first sub-routing 37, the second sub-routing 38 and the connecting sub-routing 39 is conducive to saving process steps and improving preparation efficiency.

[0056] In one embodiment, the first sub-routing 37, the second sub-routing 38 and the connecting sub-routing 39 are integrally formed. Specifically, the first sub-routing 37, the second sub-routing 38 and the connecting sub-routing 39 are simultaneously prepared using the same process, which saves process steps, improves preparation efficiency, and ensures the connection effect between the three.

[0057] See also Figure 7 The display panel 10 further includes at least one barrier dam 60, which is located between the substrate 20 and the functional layer 30, and is located in the frame area 12 and arranged around the display area 11, wherein the orthographic projection of the first wiring 31 on the substrate 20 overlaps with the orthographic projection of at least part of the barrier dam 60 on the substrate 20. Specifically, the barrier dam 60 is arranged around the display area 11, which can prevent water vapor from entering the display area 11, thereby ensuring the display effect and service life of the display panel 10. The orthographic projection of the first wiring 31 on the substrate 20 overlaps with the orthographic projection of part of the barrier dam 60 on the substrate 20, or overlaps with the orthographic projection of all the barrier dams 60 on the substrate 20, which can further save the occupied frame area and realize the narrow frame of the display panel 10.

[0058] In one embodiment, at least one barrier dam 60 includes a first barrier dam 61 and a second barrier dam 62, wherein the first barrier dam 61 is disposed around the display area 11, and the second barrier dam 62 is disposed around the first barrier dam 61, wherein the orthographic projection of the first sub-wire 37 on the substrate 20 is located between the orthographic projections of the first barrier dam 61 and the second barrier dam 62 on the substrate 20. Specifically, the step difference of the functional layer 30 on the side of the first barrier dam 61 close to the display area 11 is large, and if the first wire 31 is prepared on the side of the first barrier dam 61 close to the display area 11, abnormality is likely to occur. When the orthographic projection of the first sub-wire 37 on the substrate 20 is located between the orthographic projections of the first barrier dam 61 and the second barrier dam 62 on the substrate 20, the preparation yield of the first sub-wire 37 can be improved, the electrostatic transmission effect can be ensured, and the first sub-wire 37 can be ensured to be relatively close to the display area 11, so that the damage to the display area 11 caused by static electricity can be avoided. Of course, in other embodiments, the orthographic projection of the first sub-route 37 on the substrate 20 coincides with the orthographic projection of the second blocking dam 62 on the substrate 20, or the orthographic projection of the first sub-route 37 on the substrate 20 is located on the side of the orthographic projection of the second blocking dam 62 on the substrate 20 that is away from the display area 11. In short, the design position of the first sub-route 37 is flexible and can be selected as needed.

[0059] In one embodiment, the first wiring 31 is located in the frame area 12 and is disposed around the display area 11 , so that the first wiring 31 does not affect the display function of the display panel 10 .

[0060] In one embodiment, the width of the first line 31 is in the range of 100-500 um; specifically, the width of the first line 31 can be 100, 150, 200, 250, 300, 350, 400, 450 or 500 um. The larger width of the first line 31 can increase the metal area, attracting charges without damaging the display panel 10.

[0061] In one embodiment, the first line 31 is multiplexed as a screen crack detection line. Specifically, the first line 31 can be multiplexed in time division. For example, when the display panel 10 is tested during production, the first line 31 is multiplexed as a screen crack detection line, and the screen crack detection function interface of the driver chip is connected. After the test is completed, the driver chip can input a ground signal to the first line 31 to implement the grounding function. Alternatively, the first line 31 may not be multiplexed in time division. In this case, the first line 31 can be designed to have a grounding function, and the second line 40 can have a screen crack detection function.

[0062] In another embodiment, the first wiring 31 can be reused as one of the first touch electrode connection line or the second touch electrode connection line, in which case the touch noise can be effectively prevented to ensure the use effect. Alternatively, the second wiring 40 can be reused as the other of the first touch electrode connection line or the second touch electrode connection line to ensure the touch effect.

[0063] See also Figure 8 The first routing line 31 includes a plurality of first branch routing lines 311, and the plurality of first branch routing lines 311 are arranged at intervals. The design of the plurality of first branch routing lines 311 ensures that the function of the first routing line 31 is realized.

[0064] In other implementations, the first wiring 31 may also be a strip-shaped solid structure.
