[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0037] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0038] Please refer to Figures 1, 2 and 3. In the display panel of the related art, a VDD power line 1 and a VSS power line 2, a driving signal line 3, a touch line 4 and a cathode layer 5 are arranged in the display panel, and the VDD power line 1 and the VSS power line 2 are both located between the driving signal line 3 and the touch line 4, and the cathode layer 5 is located between the VDD power line 1 and the touch line 4. In the related art, since the driving signal line 3 is loaded with an AC signal, it is easy to cause signal interference to the touch line 4. Therefore, the cathode layer 5 is often used to shield the driving signal line 3 to reduce signal crosstalk. However, after verification, it was found that there is still relatively serious signal crosstalk at the bottom frame of the display panel, which interferes with the signal transmitted in the touch line 4 and affects the touch effect. After further research, it was found that: at the cross section shown in Figure 2, the VDD power line 1 and the cathode layer 5 are located in the first area A. 1, the VSS power line 2 is located in the second area A2, and the touch line 4 can be located in the first area A1, the second area A2 and the third area A3 at the same time; further, since the organic layer between the VDD power line 1 and the cathode layer 5 needs to be removed in the second area A2, and the area where the organic layer is removed is the fourth area A4 to prevent water vapor from invading, the VDD power line 1 will be exposed during the process; in order to prevent the cathode layer 5 from extending to the second area A2 and short-circuiting with the exposed VDD power line 1, and taking into account issues such as the manufacturing accuracy and alignment accuracy of the cathode layer 5, a safe distance needs to be reserved between the boundary of the cathode layer 5 and the fourth area A4. Therefore, the cathode layer 5 is usually confined to the first area A1, which results in the cathode layer 5 being unable to cover the third area A3, so that the lower frame corresponding to the third area A3 cannot effectively shield the signal crosstalk between the drive signal line 3 and the touch line 4 through the cathode layer 5.

[0039] Please refer to Figures 4, 5 and 6. An embodiment of the present application also provides a display panel, which includes a display area 101 and a non-display area 102 adjacent to the display area 101. The non-display area 102 includes a first wiring area 103 and a second wiring area 104 adjacent to each other, and a binding area 105 located on a side of the first wiring area 103 and the second wiring area 104 away from the display area 101.

[0040] The display panel also includes a substrate 10, a first conductive layer 20, a second conductive layer 300, and a third conductive layer 400; wherein, the first conductive layer 20 is arranged on the substrate 10, and the first conductive layer 20 includes a drive signal line 21 arranged in the first wiring area 103, and the drive signal line 21 is used to load an AC signal; the second conductive layer 300 is arranged on the side of the first conductive layer 20 away from the substrate 10, the second conductive layer 300 includes a power signal line 30, and the power signal line 30 includes a transmission part C arranged on the side of the second wiring area 104 close to the display area 101 and a connection part L connected between the transmission part C and the binding area 105; the third conductive layer 400 is arranged on the side of the second conductive layer 300 away from the first conductive layer 20, and includes a touch line 40, and the touch line 40 extends from the display area 101 to at least the first wiring area 103.

[0041] Furthermore, the second conductive layer 300 further includes a shielding portion 33 disposed in the first wiring area 103 , which is connected to the transmission portion C. The orthographic projection of the shielding portion 33 on the substrate 10 at least partially overlaps with the orthographic projection of the driving signal line 21 on the substrate 10 .

[0042] In the embodiment of the present application, a shielding portion 33 is added in the first wiring area 103. The shielding portion 33 is connected to the transmission portion C, and the shielding portion 33 is at least partially overlapped with the driving signal line 21 to shield the signal interference of the driving signal line 21 on the touch line 40. This can reduce the crosstalk between the touch line 40 and the driving signal line 21, thereby improving the touch effect of the display panel.

[0043] Specifically, please continue to combine Figures 4, 5 and 6. The display panel provided in the embodiment of the present application includes a display area 101 and a non-display area 102, and the non-display area 102 can be a four-sided border area surrounding the display area 101; wherein, in the lower border of the display panel, the non-display area 102 includes a wiring area and a binding area 105 located on the side of the wiring area away from the display area 101, and the wiring area can include a first wiring area 103 and a second wiring area 104 adjacent to the first wiring area 103.

[0044] In one embodiment, the second wiring area 104 can be connected to the opposite sides of the first wiring area 103, and the second wiring area 104 can include a first sub-area 1041 and a second sub-area 1042 respectively located on the opposite sides of the first wiring area 103, and the first sub-area 1041 is located between the first wiring area 103 and the display area 101, and the second sub-area 1042 is located between the first wiring area 103 and the binding area 105, and the arrangement of the wiring areas in subsequent embodiments is described as an example.

[0045] The display panel further includes a substrate 10 , a semiconductor layer 61 , a fourth conductive layer 50 , a first conductive layer 20 sequentially arranged on the substrate 10 , and an insulating layer arranged between any two of the semiconductor layer 61 , the fourth conductive layer 50 , the first conductive layer 20 , and the second conductive layer 300 .

[0046] Among them, the semiconductor layer 61 includes an active layer arranged in the display area 101; the fourth conductive layer 50 may include a functional signal line 51 arranged in the non-display area 102; the first conductive layer 20 includes a source, a drain and a data line, etc. arranged in the display area 101, and a driving signal line 21 arranged in the first wiring area 103, and the driving signal line 21 is used to load an alternating current signal.

[0047] In one embodiment, the driving signal line 21 is electrically connected to a multiplexing circuit, for example, it can be switched through a functional signal line 51 to be connected to the multiplexing circuit, and one multiplexing circuit can be connected to at least two data lines.

[0048] In one embodiment, the driving signal line 21 can also be used to load a clock signal, and can be switched through the functional signal line 51 to be connected to the gate driving circuit.

[0049] The display panel also includes a first organic planarizing layer 62 disposed on the first conductive layer 20, a second conductive layer 300 disposed on the first organic planarizing layer 62, a second organic planarizing layer 63 disposed on the second conductive layer 300, a pixel definition layer 64 disposed on the second organic planarizing layer 63, an organic light-emitting layer 65 disposed on the pixel definition layer 64, a cathode layer 66 and a protective layer 67 disposed on the organic light-emitting layer 65, an encapsulation layer 70 disposed on the protective layer 67, and a third conductive layer 400 disposed on the encapsulation layer 70.

[0050] Among them, the second conductive layer 300 includes a power signal line 30 arranged in the non-display area 102; the encapsulation layer 70 includes a first inorganic encapsulation layer 71, an organic encapsulation layer 72 and a third inorganic encapsulation layer 73 arranged in sequence on the protective layer 67; the third conductive layer 400 includes a touch line 40 arranged on the encapsulation layer 70.

[0051] In one embodiment, the touch line 40 may include a first touch line 41 and a second touch line 42, and one of the first touch line 41 and the second touch line 42 may be a transmitting signal line and the other may be a receiving signal line; the display panel also includes an insulating layer arranged between the touch line 40 and the packaging layer 70, between the first touch line 41 and the second touch line 42, and covering the second touch line 42.

[0052] In the embodiment of the present application, the touch trace 40 extends from the display area 101 into the non-display area 102, and may extend into the first sub-area 1041, the first wiring area 103, and the second sub-area 1042. Consequently, there is an overlap between the touch trace 40 and the drive signal line 21. Since the drive signal line 21 carries an AC signal, signal interference is easily generated on the touch trace 40. In one embodiment, the orthographic projection of the touch trace 40 on the substrate 10 at least partially overlaps with the orthographic projection of the drive signal line 21 on the substrate 10, and the extension direction of the touch trace 40 in the first wiring area 103 may be the same as or intersect with the extension direction of the drive signal line 21 in the first wiring area 103. For example, the extension direction of the touch trace 40 in the first wiring area 103 and the extension direction of the drive signal line 21 in the first wiring area 103 may both be perpendicular to the first direction X, and the first direction X is the direction from the first sub-area 1041 to the second sub-area 1042.

[0053] However, in the embodiment of the present application, the second conductive layer 300 also includes a shielding portion 33 arranged in the first wiring area 103, and the orthographic projection of the shielding portion 33 on the substrate 10 at least partially overlaps with the orthographic projection of the driving signal line 21 on the substrate 10, so as to reduce the signal crosstalk of the driving signal line 21 to the touch line 40, thereby improving the touch effect of the display panel.

[0054] Furthermore, the power signal line 30 includes a transmission portion C close to the display area 101 and a connection portion L that passes through at least the first wiring area 103 and is connected between the transmission portion C and the binding area 105, and the shielding portion 33 is connected to the transmission portion C. For details, please refer to the subsequent embodiments.

[0055] In one embodiment, a plurality of openings 330 are provided in the shielding portion 33. Since a first organic planar layer 62 is provided below the shielding portion 33, in order to prevent the first organic planar layer 62 from emitting gas in a subsequent high-temperature process, which would cause damage to the second conductive layer 300, openings 330 are provided in the second conductive layer 300 to allow gas to pass through.

[0056] In one embodiment, as shown in FIG7 , the orthographic projection of the driving signal line 21 on the substrate 10 does not overlap with the orthographic projection of the opening 330 on the substrate 10. For example, the driving signal line 21 is arranged to avoid the opening 330, or a hole is dug at a position of the driving signal line 21 corresponding to the opening 330, thereby allowing the driving signal line 21 to be more shielded by the shielding portion 33, thereby improving the shielding effect of the shielding portion 33 on signal interference.

[0057] In another embodiment, as shown in FIG8 , the orthographic projection of the driving signal line 21 on the substrate 10 partially overlaps with the orthographic projection of the opening 330 on the substrate 10. Specifically, the driving signal line 21 may include a first line 211 and a second line 212. The overlapping area of ​​the orthographic projection of the first line 211 on the substrate 10 and the orthographic projection of the opening 330 on the substrate 10 is equal to the overlapping area of ​​the orthographic projection of the second line 212 on the substrate 10 and the orthographic projection of the opening 330 on the substrate 10. The electrical signal loaded in the first line 211 overlaps with the orthographic projection of the second line 212 on the substrate 10. The electrical signals loaded therein are the same; since the first wiring 211 and the second wiring 212 overlap with the shielding portion 33, capacitance is generated to affect the loads in the first wiring 211 and the second wiring 212. In the embodiment of the present application, the areas of the first wiring 211 and the second wiring 212 exposed by the opening 330 are controlled to be the same, so that the shielding portion 33 can have the same impact on the loads of the first wiring 211 and the second wiring 212, thereby avoiding the first wiring 211 and the second wiring 212 transmitting the same signal from affecting the display effect of the display panel due to different loads.

[0058] It is understandable that the display panel further includes a driving component 80 disposed in the binding area 105 , and the connecting portion L at least passes through the first wiring area 103 and is connected between the transmission portion C and the driving component 80 .

Specifically, the first transmission portion 311 and the second transmission portion 321 are parallel to the first side 1011, while the first connection portion 312 and the second connection portion 322 intersect with the first side 1011.

The orthographic projection of the first shielding portion 331 on the substrate 10 partially overlaps with the orthographic projection of the driving signal line 21 on the substrate 10.

[0066] In one embodiment, the first shielding portion 331 and the first connecting portion 312 are connected to each other at portions located within the first wiring area 103, and within the first wiring area 103, the orthographic projection of the driving signal line 21 on the substrate 10 is located within the orthographic projection of the first shielding portion 331 and the first connecting portion 312 on the substrate 10; within the first wiring area 103, the orthographic projection of the driving signal line 21 on the substrate 10 is located within the orthographic projection of the first shielding portion 331 on the substrate 10, or, the orthographic projection of part of the driving signal line 21 on the substrate 10 is located within the orthographic projection of the first shielding portion 331 on the substrate 10, and the orthographic projection of another part of the driving signal line 21 on the substrate 10 is located within the orthographic projection of the first connecting portion 312 on the substrate 10.

[0067] It is understandable that the first shielding portion 331 can be integrally formed with the first transmission portion 311 , that is, the first shielding portion 331 can be integrally formed with the first power line 31 .

[0068] In one embodiment, a plurality of first openings 3310 are provided in the first shielding portion 331, and a plurality of third openings 310 are provided in the first transmission portion 311. Since a first organic planarization layer 62 is provided under the first shielding portion 331, in order to prevent the first organic planarization layer 62 from emitting gas in a subsequent high-temperature process, which may damage the second conductive layer 300, first openings 3310 and third openings 310 are provided in the second conductive layer 300 to allow gas to pass through.

[0069] The areas of the first opening 3310 and the third opening 310 may be the same or different, and may be selected according to actual needs, which is not limited here.

[0070] In one embodiment, the power signal line 30 is used to load a DC signal, that is, the first power line 31 and the second power line 32 are both loaded with a DC signal, and then the first shielding portion 331 is also loaded with a DC signal, which can shield the signal crosstalk generated by the AC signal loaded in the driving signal line 21 on the touch line 40, thereby improving the touch effect of the display panel.

[0071] The first shielding portion 331 is spaced apart from the second power line 32 to prevent a short circuit between the first power line 31 and the second power line 32 .

[0072] In one embodiment, the width of the area between the first sub-area 1041 and the second sub-area 1042 along the first direction X is the first width, that is, the width of the first wiring area 103 along the first direction X is the first width, the width of the first shielding portion 331 along the first direction X is the second width, and the difference between the first width and the second width is greater than or equal to 10 microns and less than or equal to 30 microns; the distance from the first shielding portion 331 to the second transmission portion 321 along the first direction X is greater than or equal to 10 microns and less than or equal to 30 microns.
