[0055] In this embodiment, the touch electrode 320 is electrically connected to the first isolation portion 310, and the touch signal of the touch electrode 320 is transmitted through the first isolation portion 310 located in the non-display area NA, which is beneficial to reduce the occupation of the light-emitting unit 500 in the display area AA by the touch electrode 320. The isolation structure layer 300 is located on the side of the driving circuit layer away from the substrate 100, that is, the third signal line 230 located in the non-display area NA is not arranged in the same layer as the first isolation portion 310, so that the position interference between the third signal line 230 and the first isolation portion 310 can be reduced, which is beneficial to reduce the frame size of the display panel and improve the process performance of the display panel.

[0056] like Figure 1 and Figure 3 As shown, in some optional embodiments, in the non-display area NA, an orthographic projection of the third signal line 230 on the substrate 100 at least partially overlaps with an orthographic projection of the first isolation portion 310 on the substrate 100 .

[0057] In these optional embodiments, the orthographic projection of the third signal line 230 on the substrate 100 at least partially overlaps with the orthographic projection of the first isolation portion 310 on the substrate 100. The stacked arrangement of the third signal line 230 and the first isolation portion 310 is beneficial to reducing the occupation of the third signal line 230 and the first isolation portion 310 in the non-display area NA, thereby reducing the size of the non-display area NA and reducing the size of the display panel frame.

The orthographic projection of the first isolation sub-portion 311 on the substrate 100 overlaps with the orthographic projection of the third signal line 230 on the substrate 100 at least partially, and the first isolation sub-portion 311 is arranged in the first non-display area NA1 to reduce the occupation of the first isolation portion 310 in the display area AA. The touch signal is transmitted through the first isolating sub-portion 311, and the orthographic projection of the first isolating sub-portion 311 on the substrate 100 at least partially overlaps with the orthographic projection of the third signal line 230 on the substrate 100, thereby helping to reduce the area of ​​the first non-display area NA1, helping to reduce the frame size of the display panel, and improving the process performance of the display panel.

[0059] Optional, such as Figure 1 As shown, the first direction X and the second direction Y are perpendicular to each other, and the first direction X and the second direction Y are parallel to the plane where the substrate 100 is located.

[0060] Optional, such as Figures 1 to 3 As shown, the first conductive layer 200 further includes a first signal line 210, and the first signal line 210 extends from the display area AA to the first non-display area NA1; the touch electrode 320 is electrically connected to the first isolation sub-portion 311 through the first signal line 210. The touch electrode 320 is connected to the first conductive layer 200, and the touch signal is transmitted to the first non-display area NA1 through the first signal line 210, so as to reduce the occupation of the isolation structure layer 300 by the touch electrode 320. The first signal line 210 is connected to the first isolation sub-portion 311, so that the touch signal of the touch electrode 320 is transmitted to the first isolation sub-portion 311 through the first signal line 210, and then transmitted to the second non-display area NA2 through the first isolation sub-portion 311.

[0061] Optional, such as Figures 1 to 4As shown, the first conductive layer 200 also includes a second signal line 220 located in the second non-display area NA2, and the first isolation portion 310 also includes a second isolation sub-portion 312 located in the second non-display area NA2, the second isolation sub-portion 312 is located between the first isolation sub-portion 311 and the second signal line 220, and one end of the second isolation sub-portion 312 is connected to the first isolation sub-portion 311, and the other end of the second isolation sub-portion 312 is electrically connected to the second signal line 220.

The arrangement area of ​​the first signal line 210 is reduced to facilitate the wiring of the third signal line 230 in the first conductive layer 200 in the first non-display area NA1, so that the first isolation sub-portion 311 and the third signal line 230 are stacked in the first non-display area NA1 along a direction perpendicular to the plane of the substrate 100, and the wiring size of the first signal line 210 and the third signal line 230 in the first non-display area NA1 along the first direction X is reduced, which is beneficial to reducing the width of the first non-display area NA1 along the first direction X, thereby realizing a narrow-frame display panel.

[0066] Optional, such as Figure 1 and Figure 3As shown, multiple first isolation sub-portions 311 are arranged side by side along the first direction X, so that multiple first isolation sub-portions 311 can be arranged in a smaller first non-display area NA1 space, allowing more first signal lines 210 to transmit electrical signals to the second non-display area NA2 through the first isolation sub-portions 311.

[0067] Optional, such as Figure 1 As shown, the first isolation portion 310 includes a plurality of second isolation sub-portions 312 , and two adjacent second isolation sub-portions 312 are arranged at intervals to isolate two adjacent second isolation sub-portions 312 , thereby achieving insulation between adjacent second isolation sub-portions 312 to reduce signal crosstalk.

[0068] As shown in Figure 1 and Figure 3 As shown, in some optional embodiments, the first conductive layer 200 includes a plurality of first signal lines 210 , and each first signal line 210 is electrically connected to each first isolation sub-portion 311 .

[0069] In these optional embodiments, each first signal line 210 is electrically connected to each first isolation sub-portion 311 , respectively, and each first isolation sub-portion 311 is arranged at intervals, thereby reducing mutual crosstalk between electrical signals of each first signal line 210 .

[0070] Optional, such as Figure 1 As shown, a plurality of first signal lines 210 are arranged side by side along the second direction Y. Each first isolating sub-portion 311 is extended along the second direction Y, so that the first isolating sub-portion 311 has an extended length in the second direction Y, which can increase the connectable points of each first isolating sub-portion 311 in the second direction Y.

[0078] In these optional embodiments, in the second non-display area NA2, the first segment 231 extends along the first direction X, and the second segment 232 is connected between the first segment 231 and the chip 400. Since the second signal line 220 intersects with the extension direction of the first segment 231, the second signal line 220 is arranged on the side of the first segment 231 away from the display area AA to avoid the second signal line 220 and the third signal line 230 from crossing.
