[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0052] Please combine Figure 1 , Figure 2 as well as Figure 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 provided in the display panel, and both the VDD power line 1 and the VSS power line 2 are 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; wherein, in the related art, since the driving signal line 3 is loaded with an alternating current 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 is found that there is still a relatively serious signal crosstalk at the lower 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 is found that: Figure 2 In the cross section shown, the VDD power line 1 and the cathode layer 5 are located in the first area A1, 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 block the invasion of water vapor, the VDD power line 1 will be exposed during the process; in order to avoid the cathode layer 5 extending to the second area A2 and short-circuiting the exposed VDD power line 1, and taking into account the production 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, so the cathode layer 5 is usually limited to the first area A1, which makes it impossible for the cathode layer 5 to cover the third area A3, so that the lower frame corresponding to the third area A3 cannot effectively shield the signal crosstalk of the drive signal line 3 to the touch line 4 through the cathode layer 5.

[0053] Please combine Figure 4 , Figure 5 as well as Figure 6An embodiment of the present invention further provides a display panel, which includes a display area 101 and a non-display area 102 adjacent to the display area 101, wherein 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.

[0056] In the embodiment of the present invention, 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 and the driving signal line 21 are at least partially overlapped to shield the signal interference of the driving signal line 21 on the touch line 40, thereby reducing the crosstalk between the touch line 40 and the driving signal line 21, thereby improving the touch effect of the display panel.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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 control line 40 arranged on the encapsulation layer 70.

[0065] 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.

[0066] In an embodiment of the present invention, the touch line 40 extends from the display area 101 to the non-display area 102, and can extend to the first sub-area 1041, the first wiring area 103 and the second sub-area 1042, so that there is an overlapping portion between the touch line 40 and the drive signal line 21. Since the drive signal line 21 is loaded with an alternating current signal, it is easy to cause signal interference to the touch line 40; in one embodiment, the orthographic projection of the touch line 40 on the substrate 10 and the orthographic projection of the drive signal line 21 on the substrate 10 at least partially overlap, and the extension direction of the touch line 40 in the first wiring area 103 can 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 line 40 in the first wiring area 103 and the extension direction of the drive signal line 21 in the first wiring area 103 can 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.

[0067] However, in an embodiment of the present invention, 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.

[0068] Furthermore, the power signal line 30 includes a transmission portion C close to the display area 101 and a connection portion L at least passing through the first wiring area 103 and connected between the transmission portion C and the binding area 105, and the shielding portion 33 is connected to the transmission portion C.

[0069] In one embodiment, a plurality of openings 330 are provided in the shielding portion 33. Since a first organic planarizing layer 62 is provided below the shielding portion 33, in order to prevent the first organic planarizing layer 62 from emitting gas in a subsequent high-temperature process, which may damage the second conductive layer 300, openings 330 are provided in the second conductive layer 300 to allow gas to pass through.

[0070] In one embodiment, if Figure 7As shown, 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 the position of the driving signal line 21 corresponding to the opening 330, so that the driving signal line 21 can be more shielded by the shielding part 33, so as to improve the shielding effect of the shielding part 33 on signal interference.

[0071] In another embodiment, if Figure 8 As shown, 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 routing line 211 and a second routing line 212. The overlapping area of ​​the orthographic projection of the first routing 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 routing 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 routing line 211 and the electrical signal loaded in the second routing line 212 are equal to the electrical signal loaded in the first routing line 211 and the electrical signal loaded in the second routing line 212. The first and second wirings 211, 212 overlap with the shielding portion 33, which will generate capacitance to affect the loads in the first and second wirings 211, 212. In the embodiment of the present invention, the areas of the first and second wirings 211, 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 and second wirings 211, 212, thereby preventing the first and second wirings 211, 212 transmitting the same signal from affecting the display effect of the display panel due to different loads.
