[0003] However, the performance of display devices with touch functions needs to be further improved. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a display panel and a display device to improve the performance of the display device.

[0005] To achieve the above purpose, the technical solution adopted in this application is:

[0006] In a first aspect, a display panel is provided, comprising a substrate, a drive device layer, an isolation structure and a touch routing, wherein the drive device layer is arranged on one side of the substrate in a thickness direction, the isolation structure is arranged on a side of the drive device layer away from the substrate, and the isolation structure defines a first isolation opening and a first light-transmitting opening, and the first isolation opening is spaced apart from the first light-transmitting opening; the touch routing is located on a side of the isolation structure away from the substrate, the touch routing comprises a first routing segment and a second routing segment connected, an orthographic projection of the first routing segment on the substrate is spaced apart from an orthographic projection of the first isolation opening on the substrate, and the orthographic projection of the second routing segment on the substrate passes through the orthographic projection of the first isolation opening on the substrate.

[0007] Through the above technical solution, the orthographic projection of the first routing segment on the substrate and the orthographic projection of the first isolation opening on the substrate are arranged at intervals, which can prevent the first routing segment from affecting the light-emitting effect at the first isolation opening, and the orthographic projection of the second routing segment on the substrate passes through the orthographic projection of the first isolation opening on the substrate, so that the second routing segment can avoid the first light-transmitting opening. This arrangement can prevent the signal of the driving device layer from passing through the first light-transmitting opening to interfere with the signal of the touch routing, which is beneficial to improving the touch performance of the display device, and further to improving the performance of the display device.

[0008] Therefore, the display panel provided by the present application can improve the performance of the display device.

[0009] In some embodiments, the orthographic projection of the first isolation opening on the substrate has a first projection portion, a second projection portion, and a third projection portion, and the first projection portion, the second projection portion, and the third projection portion are arranged in sequence along a first direction, the first direction is perpendicular to the routing direction of the second routing segment, and in the routing direction of the second routing segment, the size of the second projection portion is smaller than the size of the first projection portion and the size of the third projection portion, and the second projection portion coincides with the orthographic projection of the second routing segment on the substrate.

[0010] In this way, compared with the first projection portion and the third projection portion, the second projection portion overlaps with the orthographic projection of the second wiring segment on the substrate, which can reduce the area of ​​the first isolation opening blocked by the second wiring segment, which is beneficial to improving the light-emitting effect.

[0011] In some embodiments, in a first direction, the first isolation opening is located between two adjacent first light-transmitting openings and / or the first light-transmitting opening is located between two adjacent first isolation openings, and the first direction is perpendicular to the routing direction of the second routing segment.

[0012] In this way, the second wiring segment can avoid the first light-transmitting opening, thereby preventing the signal of the driving device layer from passing through the first light-transmitting opening and interfering with the signal of the touch wiring, which is beneficial to improving the touch performance of the display device and further improving the performance of the display device.

[0013] Optionally, the orthographic projection of the second wiring segment on the substrate is equal to the spacing distance between the orthographic projections of two adjacent first light-transmitting openings on the substrate.

[0014] In some embodiments, in a first direction, the first light-transmitting openings and the first isolation openings are arranged alternately, and the first direction is perpendicular to a routing direction of the second routing segment.

[0015] Thus, in the display panel provided in the present application, each first isolation opening is located between two adjacent first light-transmitting openings, and each first light-transmitting opening is located between two adjacent first isolation openings, so that the second wiring segment can avoid the first light-transmitting openings.

[0016] In some embodiments, the first isolation opening includes a first light-emitting area and a second light-emitting area arranged at intervals, and an orthographic projection of the second routing segment on the substrate is located between the orthographic projections of the first light-emitting area and the second light-emitting area on the substrate.

[0017] In this way, the second wiring segment will not block the light-emitting area of ​​the first isolation opening, which is beneficial to improving the light-emitting effect.

[0018] Optionally, in the orthographic projection on the substrate, the second wiring segment is spaced at equal distances from the first light-emitting area and the second light-emitting area.

[0019] Optionally, a routing direction of the second routing segment is perpendicular to a spacing direction between the first light-emitting area and the second light-emitting area.

[0020] In some embodiments, the display panel provided in the present application also includes a pixel definition layer, which is arranged between the driving device layer and the isolation structure, and includes a pixel opening group corresponding to the first isolation opening, the pixel opening group includes two adjacent and spaced pixel openings, the orthographic projections of the two pixel openings on the substrate are located within the orthographic projection of the first isolation opening on the substrate, one of the two pixel openings corresponds to the first light-emitting area, and the other corresponds to the second light-emitting area, and the orthographic projection of the second routing segment on the substrate is located between the orthographic projections of the two pixel openings on the substrate.

[0021] In this way, the orthographic projection of the pixel opening on the substrate can avoid the orthographic projection of the second wiring segment on the substrate, thereby preventing the second wiring segment from affecting the light emission.

[0022] In some embodiments, the isolation structure further defines a second isolation opening and a third isolation opening, and in the orthographic projection on the substrate, the first routing segment is located between two adjacent isolation openings, and the spacing distance between the first routing segment and the two adjacent isolation openings is equal; wherein the two adjacent isolation openings are the first isolation opening and the second isolation opening, or the two adjacent isolation openings are the first isolation opening and the third isolation opening, or the two adjacent isolation openings are the second isolation opening and the third isolation opening.

[0023] In this way, the spacing between the first routing segment and the two adjacent isolation openings is equal, thereby preventing the spacing between the first routing segment and the isolation opening from being too small. When the isolation openings and the light-transmitting openings are arranged at intervals, and the spacing between the first routing segment and the isolation openings increases, the spacing between the first routing segment and the light-transmitting openings will also increase to a certain extent, thereby preventing the signal of the driver device layer from passing through the first light-transmitting opening and interfering with the signal of the touch routing line.

[0026] Optionally, an orthographic projection of the first routing segment on the substrate is located within an orthographic projection of the isolation structure on the substrate.

[0027] In this way, the first wiring segment bypasses the second isolation opening and the third isolation opening to avoid blocking the second isolation opening and the third isolation opening, thereby facilitating improving the light-emitting effect.

[0030] In this way, the first via hole avoids the first isolation opening.

[0031] Optionally, the orthographic projection of the second routing segment on the substrate covers the orthographic projection of the first via on the substrate.

[0032] In some embodiments, the isolation structure further defines a second isolation opening, a third isolation opening, and a second light-transmitting opening, the second light-transmitting opening is located between two adjacent isolation openings, and the two adjacent isolation openings are the second isolation opening and the third isolation opening.

[0033] Optionally, the orthographic projections of two adjacent isolation openings and the second light-transmitting opening located between the two adjacent isolation openings on the substrate are located within a region enclosed by the orthographic projections of the first routing segment on the substrate.

[0034] In this way, the first wiring segment bypasses the second isolation opening, the third isolation opening and the second light-transmitting opening to avoid blocking the second isolation opening and the third isolation opening, and to a certain extent prevents the signal of the driving device layer from passing through the second light-transmitting opening to interfere with the signal of the touch wiring.

[0068] For example, the display panel of the display device of the embodiment of the present application may be an OLED display panel, which includes a display substrate and a functional film layer located on the display substrate.

[0069] Exemplarily, the functional film layer includes a touch film layer. The display panel of the display device of the embodiment of the present application has a touch function, which can improve the convenience of operation, experience, integration and other performance. However, the performance of the display device with a touch function needs to be further improved.

[0070] Please also read Figure 1 , Figure 2 and Figure 3 For example, in the related art, the display panel needs to have a hole in the display (Active Area, AA) area due to fingerprint on display (Fingerprint On Display, FOD), ambient light transmittance and other reasons.

[0071] It is understood that in the related art, the driving device layer 200 can transmit a variety of signals. For example, the driving device layer 200 can be electrically connected to the light-emitting element 500 to provide a signal to the light-emitting element 500. The light-emitting element 500 includes a first electrode 510, a light-emitting layer 520, and a second electrode 530 arranged in sequence. The first electrode 510 can be an anode, and the second electrode 530 can be a cathode. The light-emitting layer 520 is formed on the pixel definition layer 400 (Pixel Define Layer, PDL), and the first electrode 510 is located between the pixel definition layer 400 and the driving device layer 200.

[0072] The driving device layer 200 includes a plurality of insulating film layers and a plurality of first metal layers (M1), second metal layers (M2), metal oxide layers (GATO), third metal layers (M3) and fourth metal layers (M4) which are stacked and insulated from each other, and the first metal layer, the second metal layer, the metal oxide layer, the third metal layer and the fourth metal layer are sequentially arranged in a direction away from the substrate 100. The plurality of insulating film layers are respectively a first gate dielectric layer (Gate Insulator 1, GL1), a capacitor dielectric layer (CI), a buffer layer (Buffer), a second gate dielectric layer (Gate Insulator 1, GL2), an interlayer dielectric layer (Inter Layer Dielectric, ILD), a first planarization layer (Planarization 1, PLN1) and a second planarization layer (Planarization 2, PLN2) which are sequentially arranged in a direction away from the substrate 100.

[0073] It should be noted that the internal structure of the driving device layer 200 is a technology well known to those skilled in the art and is not shown in the figure.

[0074] Among them, the first metal layer is arranged between the first gate dielectric layer and the capacitor dielectric layer, the second metal layer is arranged between the capacitor dielectric layer and the buffer layer, the metal oxide layer is arranged between the second gate dielectric layer and the interlayer dielectric layer, the third metal layer is arranged between the interlayer dielectric layer and the first planarizing layer, and the fourth metal layer is arranged between the first planarizing layer and the second planarizing layer.

[0075] The driving device layer 200 is a multi-layer structure, and the driving device layer 200 also includes polysilicon (PSI) and indium gallium zinc oxide (IGZO), the polysilicon is arranged between the substrate 100 and the first gate dielectric layer, the indium gallium zinc oxide is arranged between the buffer layer and the second gate dielectric layer, and the first electrode is arranged between the second planar layer and the pixel definition layer 400. In addition, the substrate 100 is provided with a bottom light shielding layer opposite to the polysilicon.

[0076] In the case where a hole is opened in the display area, the signal transmitted by the driving device layer 200 is likely to pass through the hole in the display area and interfere with the signal of the touch wiring 800, thereby having an adverse effect on the touch performance.

[0077] Please also read Figure 4 , Figure 5 and Figure 6 In order to solve the above technical problems, an embodiment of the present application provides a display panel, including a substrate 100, a driving device layer 200 and an isolation structure 300, wherein the driving device layer 200 is arranged on one side of the substrate 100 in the thickness direction, and the isolation structure 300 is arranged on the side of the driving device layer 200 away from the substrate 100.

[0078] The isolation structure 300 defines an isolation opening 310 and a light-transmitting opening 320, and the light-emitting element 500 is disposed in the isolation opening 310. The light-transmitting opening 320 is used for ambient light transmission or fingerprint screen display. Exemplarily, the isolation structure 300 defines a first isolation opening 311 and a first light-transmitting opening 321, and the first isolation opening 311 is spaced from the first light-transmitting opening 321.

[0079] A first encapsulation layer 610, a second encapsulation layer 620 and a third encapsulation layer 630 are disposed on the side of the isolation structure 300 and the light emitting element 500 facing away from the substrate 100, and the first encapsulation layer 610, the second encapsulation layer 620 and the third encapsulation layer 630 are sequentially disposed in a direction away from the substrate 100. The first encapsulation layer 610 and the second encapsulation layer 620 are formed by chemical vapor deposition (CVD), and the second encapsulation layer 620 is formed by inkjet printing (IJP).

[0080] The display panel provided in the embodiment of the present application further includes a touch line 800, which is located on the side of the isolation structure 300 away from the substrate 100, and the touch line 800 includes a first line segment 810 and a second line segment 820 connected. The orthographic projection of the first line segment 810 on the substrate 100 and the orthographic projection of the first isolation opening 311 on the substrate 100 are arranged at intervals, which can prevent the first line segment 810 from affecting the light-emitting effect at the first light-transmitting opening 321. The orthographic projection of the second line segment 820 on the substrate 100 passes through the orthographic projection of the first isolation opening 311 on the substrate 100, so that the second line segment 820 can avoid the first light-transmitting opening 321.

[0081] In this way, the display panel provided by the embodiment of the present application can prevent the signal of the driving device layer 200 from interfering with the signal of the touch wiring 800 through the first light-transmitting opening 321, which is beneficial to improving the touch performance of the display device and further to improving the performance of the display device.

[0082] Therefore, the display panel provided by the present application can improve the performance of the display device.

[0083] Optionally, the orthographic projection of the first routing segment 810 on the substrate 100 is located within the orthographic projection of the isolation structure 300 on the substrate 100 , so that the first routing segment 810 can avoid the first light-transmitting opening 321 .

[0084] It can be understood that the first encapsulation layer 610, the second encapsulation layer 620 and the third encapsulation layer 630 are located between the touch wiring 800 and the isolation structure 300, that is, the touch wiring 800 is located on the side of the third encapsulation layer 630 away from the substrate 100. The touch wiring 800 is generally divided into two layers, the touch wiring 800 includes a first layer wiring 801 and a second layer wiring 802, and the third encapsulation layer 630 is provided with an insulating layer 700 on the side away from the substrate 100, and the insulating layer 700 is located between the first layer wiring 801 and the second layer wiring 802.

[0085] Please continue reading Figure 4 and Figure 5 In some embodiments, the orthographic projection (not shown) of the first isolation opening 311 on the substrate 100 includes a first projection portion, a second projection portion, and a third projection portion, and the first projection portion, the second projection portion, and the third projection portion are along the first direction (such as Figure 4 The first direction is perpendicular to the routing direction of the second routing segment 820 (eg, Figure 4 in the X direction).

[0086] In the routing direction of the second routing segment 820, the size of the second projection portion is smaller than the size of the first projection portion and the size of the third projection portion, and the second projection portion coincides with the orthographic projection of the second routing segment 820 on the substrate 100. In other words, the size of the first isolation opening 311 in the routing direction of the second routing segment 820 first decreases and then increases along the first direction.

[0087] In this way, when the width of the second routing segment 820 (the size of the second routing segment 820 in the Y direction) remains unchanged, compared with the first projection portion and the third projection portion, the second projection portion coincides with the orthographic projection of the second routing segment 820 on the substrate 100, which can reduce the area of ​​the first isolation opening 311 being blocked, which is beneficial to improving the light-emitting effect.

[0088] In some embodiments, the isolation structure 300 is provided with a protrusion 330 protruding toward the first isolation opening 311, and the orthographic projection of the second routing segment 820 on the substrate 100 overlaps with the orthographic projection of the protrusion 330 on the substrate 100. Such a configuration can reduce the area of ​​the first isolation opening 311 blocked by the second routing segment 820.

[0089] Exemplarily, the orthographic projection of the protrusion 330 on the substrate 100 coincides with the orthographic projection of the second routing segment 820 on the substrate 100 .

[0090] Exemplarily, the orthographic projection of the protrusion 330 on the substrate 100 is located within the orthographic projection of the second routing segment 820 on the substrate 100 .

[0091] Exemplarily, the orthographic projection of the second routing segment 820 on the substrate 100 is located between two opposite sides of the protrusion 330 in the first direction. In other words, the width of the second routing segment 820 is smaller than the size of the protrusion 330 in the first direction. In this way, in the first direction, the second routing segment 820 is located in the middle of the first isolation opening 311, so that the distance between the second routing segment 820 and the two opposite sides of the first isolation opening 311 in the first direction can be equal, thereby avoiding to a certain extent that the distance between the second routing segment 820 and the first light-transmitting opening 321 is too small.

[0092] For example, when the first light-transmitting opening 321 and the first isolation opening 311 are spaced apart in the first direction, the spacing distance between the second routing segment 820 and the first light-transmitting opening 321 is greater than half of the size of the first isolation opening 311 in the first direction. This can, to a certain extent, avoid the signal of the driving device layer 200 passing through the first light-transmitting opening 321 and interfering with the signal of the touch routing 800, which is beneficial to improving the touch performance of the display device, and further beneficial to improving the performance of the display device.

[0093] It should be noted that the spacing distance is the distance between the mutually adjacent sides of two spaced structures. For example, the first structure and the second structure are spaced apart, and the spacing distance between the first structure and the second structure is the distance between the side of the first structure close to the second structure and the side of the second structure close to the first structure.

[0094] Please continue reading Figure 4 and Figure 6 In some embodiments, in the first direction, the orthographic projection of the first isolation opening 311 on the substrate 100 is located between the orthographic projections of two adjacent first light-transmitting openings 321 on the substrate 100, and / or the orthographic projection of the first light-transmitting opening 321 on the substrate 100 is located between the orthographic projections of two adjacent first isolation openings 311 on the substrate 100.

[0095] The second wiring segment 820 can avoid the first light-transmitting opening 321 , thereby preventing the signal of the driving device layer 200 from passing through the first light-transmitting opening 321 and interfering with the signal of the touch wiring 800 , which is beneficial to improving the touch performance of the display device and further to improving the performance of the display device.

[0096] Exemplarily, the orthographic projection of the first isolation opening 311 on the substrate 100 is located between the orthographic projections of two adjacent first light-transmitting openings 321 on the substrate 100 .

[0097] Exemplarily, the orthographic projection of the first light-transmitting opening 321 on the substrate 100 is located between the orthographic projections of two adjacent first isolation openings 311 on the substrate 100 .

[0098] Exemplarily, in the first direction, the first light-transmitting openings 321 and the first isolation openings 311 are arranged alternately. That is, the orthographic projection of the first isolation openings 311 on the substrate 100 is located between the orthographic projections of two adjacent first light-transmitting openings 321 on the substrate 100, and the orthographic projection of the first light-transmitting openings 321 on the substrate 100 is located between the orthographic projections of two adjacent first isolation openings 311 on the substrate 100.

[0099] Thus, in the display panel provided in the present application, each first isolation opening is located between two adjacent first light-transmitting openings, and each first light-transmitting opening is located between two adjacent first isolation openings, so that the second wiring segment can avoid the first light-transmitting openings.

[0100] Exemplarily, the distance between the orthographic projection of the second routing segment 820 on the substrate 100 and the orthographic projection of two adjacent first light-transmitting openings 321 on the substrate 100 is equal. In other words, the distance between the orthographic projection of the second routing segment 820 on the substrate 100 and the orthographic projection of one of the two adjacent first light-transmitting openings 321 on the substrate 100 is equal to the distance between the orthographic projection of the second routing segment 820 on the substrate 100 and the orthographic projection of the other of the two adjacent first light-transmitting openings 321 on the substrate 100.

[0101] In this way, the spacing distance between the second routing segment 820 and the first light-transmitting opening 321 is greater than half of the size of the first isolation opening 311 in the first direction, which can to a certain extent avoid the signal of the driving device layer 200 from passing through the first light-transmitting opening 321 and interfering with the signal of the touch routing 800, which is beneficial to improving the touch performance of the display device, and further beneficial to improving the performance of the display device.

[0102] See also Figure 7 In some embodiments, the first isolation opening 311 includes a first light-emitting area 3111 and a second light-emitting area 3112 arranged at intervals, and the orthographic projection of the second routing segment 820 on the substrate 100 is located between the orthographic projection of the first light-emitting area 3111 on the substrate 100 and the orthographic projection of the second light-emitting area 3112 on the substrate 100.

[0103] In this way, the second wiring segment 820 will not block the light-emitting area of ​​the first isolation opening 311, which is beneficial to improving the light-emitting effect.

[0104] Exemplarily, the routing direction of the second routing segment 820 is perpendicular to the spacing direction of the first light-emitting area 3111 and the second light-emitting area 3112. Exemplarily, the spacing direction of the first light-emitting area 3111 and the second light-emitting area 3112 is the first direction.

[0105] Exemplarily, the spacing distance between the orthographic projection of the second wiring segment 820 on the substrate 100 and the orthographic projection of the first light-emitting area 3111 on the substrate 100 is equal to the spacing distance between the orthographic projection of the second wiring segment 820 on the substrate 100 and the orthographic projection of the second light-emitting area 3112 on the substrate 100. In this way, the spacing distance between the second wiring segment 820 and the first light-transmitting opening 321 is greater than half of the size of the first isolation opening 311 in the first direction, which can avoid, to a certain extent, the signal of the driving device layer 200 passing through the first light-transmitting opening 321 to interfere with the signal of the touch wiring 800, which is beneficial to improving the touch performance of the display device, and further to improving the performance of the display device.

[0106] In some embodiments, the display panel provided by the embodiments of the present application further includes a pixel definition layer 400 , and the pixel definition layer 400 is disposed between the driving device layer 200 and the isolation structure 300 .

[0107] The pixel definition layer 400 includes a pixel opening group corresponding to the first isolation opening 311, the pixel opening group includes two adjacent and spaced pixel openings 401, the orthographic projections of the two pixel openings 401 on the substrate 100 are located within the orthographic projection of the first isolation opening 311 on the substrate 100, one of the two pixel openings 401 corresponds to the first light-emitting area 3111, the other of the two pixel openings 401 corresponds to the second light-emitting area 3112, and the orthographic projection of the second routing segment 820 on the substrate 100 is located between the orthographic projections of the two pixel openings 401 on the substrate 100.

[0108] In this way, the orthographic projection of the pixel opening on the substrate can avoid the orthographic projection of the second wiring segment on the substrate, thereby preventing the second wiring segment from affecting the light emission.

[0109] It should be noted that the light emitting elements 500 corresponding to the two pixel openings 401 in the pixel opening group can emit light of the same color, such as blue light.

[0110] Please continue reading Figure 4 , Figure 6 and Figure 7 In some embodiments, the isolation structure 300 further defines a second isolation opening 312 and a third isolation opening 313, and the orthographic projection of the first routing segment 810 on the substrate 100 is located between the orthographic projections of two adjacent isolation openings 310 on the substrate 100, and the spacing distance between the first routing segment 810 and the two adjacent isolation openings 310 is equal.

[0111] In other words, the orthographic projection of one of the two adjacent isolation openings 310 on the substrate 100 is located on one side of the orthographic projection of the first routing segment 810 on the substrate 100 , and the orthographic projection of the other of the two adjacent isolation openings 310 on the substrate 100 is located on the other side opposite to the orthographic projection of the first routing segment 810 on the substrate 100 .

[0112] In addition, the orthographic projection of the first routing segment 810 on the substrate 100 is located at an equal distance between the orthographic projections of two adjacent isolation openings 310 on the substrate 100. In other words, the orthographic projection of one of the two adjacent isolation openings 310 on the substrate 100 and the orthographic projection of the first routing segment 810 on the substrate 100 are equal to the orthographic projection of the other of the two adjacent isolation openings 310 on the substrate 100 and the orthographic projection of the first routing segment 810 on the substrate 100.

[0113] Exemplarily, two adjacent isolation openings 310 are a first isolation opening 311 and a second isolation opening 312. Exemplarily, two adjacent isolation openings 310 are a first isolation opening 311 and a third isolation opening 313. Exemplarily, two adjacent isolation openings 310 are a second isolation opening 312 and a third isolation opening 313.

[0114] In this way, the spacing distance between the first routing segment 810 and the two adjacent isolation openings 310 is equal, which can avoid the spacing distance between the first routing segment 810 and the isolation opening 310 being too small to a certain extent. It can be understood that when the isolation opening 310 and the light-transmitting opening 320 are arranged at intervals, and the spacing distance between the first routing segment 810 and the light-transmitting opening 320 increases, the spacing distance between the first routing segment 810 and the light-transmitting opening 320 will also increase to a certain extent, thereby avoiding the signal of the driving device layer 200 passing through the first light-transmitting opening 321 to interfere with the signal of the touch wiring 800 to a certain extent.

[0115] It can be understood that the light emitting element 500 (first light emitting element) corresponding to the first isolation opening 311 can emit the first light among blue light, red light, and green light. The light emitting element 500 (second light emitting element) corresponding to the second isolation opening 312 can emit the second light among blue light, red light, and green light. The light emitting element 500 (third light emitting element) corresponding to the third isolation opening 313 can emit the third light among blue light, red light, and green light.

[0116] Exemplarily, the display panel provided in the embodiment of the present application further includes a first light-emitting element corresponding to the first isolation opening 311, a second light-emitting element corresponding to the second isolation opening 312, and a third light-emitting element corresponding to the third isolation opening 313. The first light-emitting element is used to emit blue light, that is, the light-emitting layer 520 in the first isolation opening 311 corresponds to a blue (Blue, B) pixel. The second light-emitting element is used to emit red light, that is, the light-emitting layer 520 in the second isolation opening 312 corresponds to a red (Red, R) pixel. The third light-emitting element is used to emit green light, that is, the light-emitting layer 520 in the third isolation opening 313 corresponds to a green (Green, G) pixel.

[0117] In this way, the display panel provided in the embodiment of the present application can emit light and display images.

[0118] Optionally, the first routing segment 810 surrounds the second isolation opening 312 and / or the third isolation opening 313 , and the first routing segment 810 does not affect the light emitting effect at the second isolation opening 312 and / or the third isolation opening 313 .

[0119] Exemplarily, the first routing segment 810 surrounds the second isolation opening 312 .

[0120] Exemplarily, the first routing segment 810 surrounds the third isolation opening 313 .

[0121] Exemplarily, the first routing segment 810 surrounds the second isolation opening 312 and the third isolation opening 313 .

[0122] In some embodiments, the orthographic projections of two adjacent isolation openings 310 on the substrate 100 are located within a region enclosed by the orthographic projections of the first routing segment 810 on the substrate 100 , and the two adjacent isolation openings 310 are the second isolation opening 312 and the third isolation opening 313 .

[0123] In this way, the first wiring segment 810 bypasses the second isolation opening 312 and the third isolation opening 313 to avoid blocking the second isolation opening 312 and the third isolation opening 313 , thereby facilitating improving the light emitting effect.

[0124] In some embodiments, the isolation structure 300 further defines a second light-transmitting opening 322 . The second light-transmitting opening 322 is located between two adjacent isolation openings 310 . The two adjacent isolation openings 310 are the second isolation opening 312 and the third isolation opening 313 .

[0125] Exemplarily, two adjacent isolation openings 310 are spaced apart in the first direction, that is, the second isolation opening 312 and the third isolation opening 313 are spaced apart in the first direction.

[0126] Optionally, the orthographic projections of two adjacent isolation openings 310 and the second light-transmitting opening 322 located between the two adjacent isolation openings 310 in the first direction on the substrate 100 are located within a region enclosed by the orthographic projection of the first routing segment 810 on the substrate 100 .

[0127] That is, the orthographic projections of the adjacent second isolation opening 312 and the third isolation opening 313 on the substrate 100 are located within the area enclosed by the orthographic projections of the first routing segment 810 on the substrate 100. Furthermore, the orthographic projection of the second light-transmitting opening 322 on the substrate 100 is located within the area enclosed by the orthographic projections of the first routing segment 810 on the substrate 100, wherein the second light-transmitting opening 322 is located between the second isolation opening 312 and the third isolation opening 313.

[0128] Exemplarily, in the first direction, the second isolation openings 312 and the third isolation openings 313 are arranged alternately, that is, each second isolation opening 312 is located between two adjacent third isolation openings 313 , and each third isolation opening 313 is located between two adjacent second isolation openings 312 .

[0129] In this way, the first wiring segment 810 bypasses the second isolation opening 312 and the third isolation opening 313, which can avoid blocking the second isolation opening 312 and the third isolation opening 313. In addition, the first wiring segment 810 bypasses the second light-transmitting opening 322, which can also prevent the signal of the driving device layer 200 from passing through the second light-transmitting opening 322 to interfere with the signal of the touch wiring 800 to a certain extent.

[0130] Please continue reading Figure 4 , Figure 6 and Figure 7 In some embodiments, the display panel provided in the embodiments of the present application further includes a first light emitting element corresponding to the first isolation opening 311, the driving device layer 200 is provided with a first via hole 201, the anode of the first light emitting element extends into the first via hole 201, and the orthographic projection of the second routing segment 820 on the substrate 100 overlaps with the orthographic projection of the first via hole 201 on the substrate 100. At least part of the orthographic projection of the first via hole 201 on the substrate 100 is located within the orthographic projection of the protrusion 330 on the substrate 100.

[0131] Exemplarily, the orthographic projection of the first via 201 on the substrate 100 coincides with the orthographic projection of the second routing segment 820 on the substrate 100 .

[0132] Exemplarily, a portion of the orthographic projection of the first via 201 on the substrate 100 coincides with the orthographic projection of the second routing segment 820 on the substrate 100 .

[0133] Exemplarily, the second routing segment 820 covers the first via hole 201 . That is, the orthographic projection of the first via hole 201 on the substrate 100 is located within the orthographic projection of the second routing segment 820 on the substrate 100 .

[0134] Exemplarily, in the routing direction of the second routing segment 820 , the orthographic projection of the first via hole 201 on the substrate 100 is located on one side of the second projection portion, so that the first via hole 201 avoids the first isolation opening 311 .

[0135] Exemplarily, in the thickness direction of the substrate 100 , the first via hole 201 passes through the protrusion 330 .

[0136] In this way, the first via 201 avoids the first isolation opening 311. In addition, when the width of the second routing segment 820 (the size of the second routing segment 820 in the Y direction) remains unchanged, compared with the first projection portion and the third projection portion, the orthographic projection of the second routing segment 820 on the substrate 100 overlaps with the second projection portion, which can reduce the area of ​​the first isolation opening 311 being blocked, which is beneficial to improving the light-emitting effect.

[0137] In some embodiments, the display panel provided by the embodiments of the present application also includes a second light-emitting element corresponding to the second isolation opening 312, the driving device layer 200 is provided with a plurality of second vias 202, the anode of the second light-emitting element extends into the second via 202, and the orthographic projection of the second via 202 on the substrate 100 is located within the projection of the second light-transmitting opening 322 on the substrate 100.

[0138] In addition, the display panel provided in the embodiment of the present application further includes a third light emitting element corresponding to the third isolation opening 313, and the anode of the third light emitting element also extends into the second via hole 202. The anode of the second light emitting element and the anode of the third light emitting element extend into different second via holes 202.

[0139] In this way, the second via hole 202 can avoid the second isolation opening 312 and the third isolation opening 313 , which is beneficial to improving the light emitting effect.

[0140] Please participate Figure 8 In some embodiments, the touch routing 800 further includes a third routing segment 830, the orthographic projection of the third routing segment 830 on the substrate 100 is located within the area enclosed by the orthographic projection of the first routing segment 810 on the substrate 100, and the routing direction of the third routing segment 830 (such as Fig. 9 The X direction in the figure is perpendicular to the first direction; wherein the third routing segment 830 is a virtual structure disconnected from the first routing segment 810.

[0141] In this way, when the third wiring segment 830 passes through the second light-transmitting opening 322 , the display panel provided by the embodiment of the present application can, to a certain extent, prevent the signal of the driving device layer 200 from interfering with the signal of the touch wiring 800 through the second light-transmitting opening 322 .

[0142] Exemplarily, a portion of the orthographic projection of the third routing segment 830 on the substrate 100 is located between the orthographic projections of the second isolation opening 312 and the second light-transmitting opening 322 on the substrate 100. Exemplarily, a portion of the orthographic projection of the third routing segment 830 on the substrate 100 is located between the third isolation opening 313 and the second light-transmitting opening 322. Exemplarily, some portions of the orthographic projection of the third routing segment 830 on the substrate 100 are located between the orthographic projections of the second isolation opening 312 and the second light-transmitting opening 322 on the substrate 100, and some portions of the orthographic projection of the third routing segment 830 on the substrate 100 are located between the orthographic projections of the third isolation opening 313 and the second light-transmitting opening 322 on the substrate 100. The orthographic projection of the third routing segment 830 on the substrate 100 is located between the orthographic projections of the second isolation opening 312 and the third isolation opening 313 on the substrate 100.

[0143] In this way, a part of the orthographic projection of the third wiring segment 830 on the substrate 100 overlaps with the orthographic projection of the isolation structure 300 on the substrate 100 , which can reduce the area of ​​the second light-transmitting opening 322 or the second isolation opening 312 or the third isolation opening 313 being blocked.

[0144] See also Fig. 9 In other embodiments, different from the above embodiments, the third routing segment 830 is connected to the first routing segment 810 and / or the second routing segment 820, which can increase the routing density of the touch routing 800, which is beneficial to improve the touch performance to a certain extent.

[0145] Exemplarily, part of the orthographic projection of the third routing segment 830 on the substrate 100 is located between the orthographic projections of the second isolation opening 312 and the second light-transmitting opening 322 on the substrate 100 , and the other part of the orthographic projection of the third routing segment 830 on the substrate 100 coincides with the orthographic projection of the second light-transmitting opening 322 on the substrate 100 .

[0147] This can reduce the area of ​​the second light-transmitting opening 322 without blocking the second isolation opening 312 and the third isolation opening 313 , and can also reduce the interference of the signal of the driving device layer 200 passing through the second light-transmitting opening 322 on the signal of the touch wiring 800 to a certain extent.

[0148] Exemplarily, part of the orthographic projection of the third routing segment 830 on the substrate 100 is located between the orthographic projections of the second isolation opening 312 and the second light-transmitting opening 322 on the substrate 100 , and the other part of the orthographic projection of the third routing segment 830 on the substrate 100 coincides with the orthographic projection of the second isolation opening 312 on the substrate 100 .

[0149] Exemplarily, part of the orthographic projection of the third routing segment 830 on the substrate 100 is located between the orthographic projections of the third isolation opening 313 and the second light-transmitting opening 322 on the substrate 100 , and the other part of the orthographic projection of the third routing segment 830 on the substrate 100 coincides with the orthographic projection of the third isolation opening 313 on the substrate 100 .

[0150] In this way, the area of ​​the second light-transmitting opening 322 being blocked can be reduced, and the second light-transmitting opening 322 will not be blocked, thereby reducing the interference of the signal of the driving device layer 200 passing through the second light-transmitting opening 322 on the signal of the touch wiring 800 to a certain extent.

[0151] Optionally, the orthographic projection of the third routing segment 830 on the substrate 100 partially overlaps with the orthographic projection of the second light-transmitting opening 322 on the substrate 100, and a shielding layer (not shown in the figure) is provided in the second light-transmitting opening 322, and the shielding layer is arranged on the same layer as the cathode of the second light-emitting element and / or the third light-emitting element.

[0152] Exemplarily, the shielding layer is disposed at the same layer as the cathode of the second light emitting element.

[0153] Exemplarily, the shielding layer is disposed at the same layer as the cathode of the third light emitting element.

[0154] Exemplarily, the shielding layer is disposed on the same layer as the cathodes of the second light-emitting element and the third light-emitting element.

[0155] In this way, the shielding layer can prevent the third wiring segment 830 from being disturbed to a certain extent.

In the routing direction of the third routing segment 830, the third routing segment 830 includes a first segment 831 and a second segment 832 arranged in different layers. The orthographic projections of the first segment 831 and the second segment 832 on the substrate 100 are both located between the orthographic projection of the second isolation opening 312 on the substrate 100 and the orthographic projection of the third isolation opening 313 on the substrate 100.

In this way, the third routing segment 830 avoids the second isolation opening 312 and the third isolation opening 313, so as to avoid affecting the light-emitting effect at the second isolation opening 312 and the third isolation opening 313.

[0161] Exemplarily, the first section and the second section are connected via a line-changing hole, and the orthographic projection of the line-changing hole on the substrate is located between the orthographic projection of the second isolation opening on the substrate and the orthographic projection of the third isolation opening on the substrate.
