Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display, and more particularly relates to a display panel and a display device. BACKGROUND

[0002] Touch technology can improve the performance of operation convenience, experience, integration, etc., and is widely used in products such as mobile phones, televisions, tablet computers, notebook computers, desktop computers, vehicle-mounted display terminals, wearable devices, and advertising display devices.

[0003] However, the use performance of the display device with the touch function needs to be further improved. SUMMARY

[0004] The display panel and the display device provided by the embodiments of the present application can improve the use performance of the display device.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present application is:

[0006] In a first aspect, a display panel is provided, comprising a substrate, a driving device layer, an isolation structure, and a touch trace. The driving device layer is arranged on one side of the substrate in the thickness direction. The isolation structure is arranged on a side of the driving device layer away from the substrate, and the isolation structure defines a first isolation opening and a first light transmission opening. The first isolation opening and the first light transmission opening are arranged in a spaced manner. The touch trace is arranged on a side of the isolation structure away from the substrate. The touch trace comprises a first trace segment and a second trace segment connected in series. The first trace segment is arranged in a spaced manner with the first isolation opening in the substrate. The second trace segment is arranged in a manner that the projection of the second trace segment in the substrate passes through the projection of the first isolation opening in the substrate.

[0007] According to the above technical solution, the first trace segment is arranged in a spaced manner with the first isolation opening in the substrate, so as to avoid the influence of the first trace segment on the light emission effect at the first isolation opening. The second trace segment is arranged in a manner that the projection of the second trace segment in the substrate passes through the projection of the first isolation opening in the substrate, so as to avoid the first light transmission opening. In this way, the signal of the driving device layer can be prevented from interfering with the signal of the touch trace through the first light transmission opening, which is conducive to improving the touch performance of the display device, and further improving the use performance of the display device.

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

[0009] In some embodiments, the first projection of the first isolation opening on the substrate has a first projection portion, a second projection portion and a third projection portion, 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 second trace direction, and in the second trace direction, 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 second trace on the substrate.

[0010] In this way, compared with the first projection portion and the third projection portion, the second projection portion coincides with the second trace on the substrate, which can reduce the area of the second trace shielding the first isolation opening, and is conducive to improving the light emitting effect.

[0011] In some embodiments, in the first direction, the first isolation opening is located between two adjacent first light transmission openings, and / or the first light transmission opening is located between two adjacent first isolation openings, and the first direction is perpendicular to the second trace direction.

[0012] In this way, the second trace can avoid the first light transmission opening, so that the signal of the driving device layer can avoid interfering with the signal of the touch trace through the first light transmission opening, which is conducive to improving the touch performance of the display device, and further conducive to improving the use performance of the display device.

[0013] Optionally, the second trace on the substrate coincides with the interval distance between the projections of the two adjacent first light transmission openings on the substrate.

[0014] In some embodiments, in the first direction, the first light transmission opening and the first isolation opening are staggered, and the first direction is perpendicular to the second trace direction.

[0015] In this way, in the display panel provided in the present application, each first isolation opening is located between two adjacent first light transmission openings, and each first light transmission opening is located between two adjacent first isolation openings, so that the second trace can avoid the first light transmission opening.

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

[0017] In this way, the second trace does not shield the light emitting area of the first isolation opening, which is conducive to improving the light emitting effect.

[0018] Optionally, in the projection on the substrate, the interval distance between the second trace and the first light emitting area and the second light emitting area is equal.

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

[0020] In some embodiments, the display panel provided in this application further includes a pixel definition layer, which is disposed 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-apart pixel openings. The orthographic projection of the two pixel openings on the substrate is 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. The orthographic projection of the second trace segment on the substrate is located between the orthographic projections of the two pixel openings on the substrate.

[0021] In this way, the orthogonal projection of the pixel opening onto the substrate can avoid the orthogonal projection of the second trace onto the substrate, thereby preventing the second trace from affecting light emission.

[0022] In some embodiments, the isolation structure further defines a second isolation opening and a third isolation opening, wherein in the orthographic projection on the substrate, a first trace segment is located between two adjacent isolation openings, and the first trace segment is equidistant from the two adjacent isolation openings; 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 trace segment and the two adjacent isolation openings is equal, avoiding the spacing between the first trace segment and the isolation opening being too small. Furthermore, the isolation openings and light-transmitting openings are arranged alternately. Increasing the spacing between the first trace segment and the isolation opening will also increase the spacing between the first trace segment and the light-transmitting opening to some extent, thereby preventing signals from the driver layer passing through the first light-transmitting opening from interfering with the signals of the touch traces.

[0024] Optionally, the first routing segment surrounds the second isolation opening and / or the third isolation opening.

[0025] Optionally, the orthographic projections of two adjacent isolation openings on the substrate are located within the area enclosed by the orthographic projection of the first trace segment on the substrate, and the two adjacent isolation openings are the second isolation opening and the third isolation opening.

[0026] Optionally, the orthographic projection of the first trace segment on the substrate lies within the orthographic projection of the isolation structure on the substrate.

[0027] In this way, the first routing segment bypasses the second and third isolation openings, avoiding obstruction of the second and third isolation openings, which helps to improve the light-emitting effect.

[0028] In some embodiments, the isolation structure has a protrusion that protrudes toward the first isolation opening, and the orthographic projection of the second trace segment on the substrate overlaps with the orthographic projection of the protrusion on the substrate.

[0029] Optionally, the display panel provided in this application further includes a first light-emitting element corresponding to the first isolation opening, a first via is provided in the driving device layer, the anode of the first light-emitting element extends into the first via, and the orthographic projection of the second trace segment on the substrate overlaps with the orthographic projection of the first via on the substrate.

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

[0031] Optionally, the orthographic projection of the second trace 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 being located between two adjacent isolation openings, the two adjacent isolation openings being the second isolation opening and the third isolation opening.

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

[0034] In this way, the first trace bypasses the second isolation opening, the third isolation opening, and the second light-transmitting opening, which can avoid blocking the second isolation opening and the third isolation opening, and can also prevent the signals of the driving device layer from interfering with the signals of the touch trace by passing through the second light-transmitting opening to a certain extent.

[0035] Optionally, the display panel provided in this application further includes a second light-emitting element corresponding to the second isolation opening and a third light-emitting element corresponding to the third isolation opening. The driving device layer is provided with a second via. The orthographic projection of the second via on the substrate is located within the projection of the second light-transmitting opening on the substrate. The anodes of the second light-emitting element and the anodes of the third light-emitting element extend into different second vias.

[0036] In some implementations, the second isolation opening and the third isolation opening are staggered in a first direction, which is perpendicular to the routing direction of the second trace segment.

[0037] In some embodiments, the display panel further includes a first light-emitting element corresponding to the first isolation opening, a second light-emitting element corresponding to the second isolation opening, and a third light-emitting element corresponding to the third isolation opening, wherein the first light-emitting element is used to emit blue light, the second light-emitting element is used to emit red light, and the third light-emitting element is used to emit green light.

[0038] In some embodiments, the touch trace further includes a third trace segment, the orthographic projection of the third trace segment on the substrate being located within the area enclosed by the orthographic projection of the first trace segment on the substrate, and the trace direction of the third trace segment being perpendicular to the first direction, the first direction being perpendicular to the trace direction of the second trace segment; wherein, the third trace segment is connected to the first trace segment and / or the second trace segment, or, the third trace segment is a virtual structure disconnected from the first trace segment.

[0039] In this way, connecting the third trace segment to the first trace segment increases the trace density of the touch traces, which helps to improve touch performance to some extent. In addition, the third trace segment is a virtual structure disconnected from the first trace segment, which can prevent the signals of the driver device layer from interfering with the signals of the touch traces when the third trace segment passes through the light-transmitting opening.

[0040] Optionally, a portion of the orthogonal projection of the third trace segment onto the substrate is located between the orthogonal projections of the second isolation opening and the second light-transmitting opening onto the substrate, and / or, a portion of the orthogonal projection of the third trace segment onto the substrate is located between the orthogonal projections of the third isolation opening and the second light-transmitting opening onto the substrate.

[0041] Optionally, the display panel provided in this application further includes a second light-emitting element corresponding to the second isolation opening and / or a third light-emitting element corresponding to the third isolation opening. The orthographic projection of the third trace segment on the substrate partially overlaps with the orthographic projection of the second light-transmitting opening on the substrate. A shielding layer is provided in the second light-transmitting opening, and the shielding layer is disposed on the same layer as the cathode of the second light-emitting element and / or the third light-emitting element.

[0042] Optionally, in the extension direction of the second trace segment, one end of the second trace segment is connected to the first segment of a third trace segment, and the other end of the second trace segment is connected to the second segment of another third trace segment; the second trace segment includes a target trace segment, the first segment of the third trace segment connected to the target trace segment, the second segment of another third trace segment connected to the target trace segment, and the target trace segment are disposed on the same layer and constitute a bridging portion; in the extension direction of the second trace segment, the touch traces located at both ends of the bridging portion are connected through the bridging portion; in the first direction, the orthographic projection of the bridging portion 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.

[0043] In some embodiments, the touch trace further includes a third trace segment, the orthographic projection of which on the substrate is located within the area enclosed by the orthographic projection of the first trace segment on the substrate, and the trace direction of the third trace segment is perpendicular to a first direction, the first direction being perpendicular to the trace direction of the second trace segment; wherein, the third trace segment is connected to the first trace segment, and in the trace direction of the third trace segment, the third trace segment includes a first segment and a second segment disposed in different layers, the first segment and the second segment being connected through a wire-changing hole, the orthographic projection of the wire-changing hole on the substrate being 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; or, the third trace segment is connected to the first trace segment, and in the trace direction of the third trace segment, the third trace segment includes a first segment and a second segment disposed in different layers, the orthographic projections of which on the substrate are both 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.

[0044] Secondly, this application provides a display panel, including a substrate, a driving device layer, an isolation structure, and touch traces. The driving device layer is disposed on one side of the substrate in the thickness direction, and the isolation structure is disposed on the side of the driving device layer away from the substrate. The isolation structure defines a first isolation opening, a second isolation opening, a third isolation opening, and a first light-transmitting opening spaced apart from the first isolation opening, the second isolation opening, and the third isolation opening. The touch traces are located on the side of the isolation structure away from the substrate. The touch traces include a first trace segment and a second trace segment connected together. The first trace segment surrounds the second isolation opening and / or the third isolation opening, and the orthographic projection of the second trace segment on the substrate passes through the orthographic projection of the first isolation opening on the substrate.

[0045] Through the above technical solution, the first trace segment surrounds the second isolation opening and / or the third isolation opening, which can prevent the first trace segment from affecting the light-emitting effect at the second isolation opening and / or the third isolation opening. The orthogonal projection of the second trace segment on the substrate passes through the orthogonal projection of the first isolation opening on the substrate, which allows the second trace segment to avoid the first light-transmitting opening. This arrangement can prevent the signal of the driving device layer from interfering with the signal of the touch trace through the first light-transmitting opening, which is beneficial to improving the touch performance of the display device, and thus improving the performance of the display device.

[0063] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0066] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0067] This application provides a display device, which can be a mobile phone, television, tablet computer, laptop computer, desktop computer, in-vehicle display terminal, wearable device, advertising display device, or other products. The display device includes a display panel, which can be an organic light-emitting diode (OLED) display panel, a micro light-emitting diode (Micro LED / μLED) display panel, or a liquid crystal display (LCD) display panel.

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

[0069] For example, the functional film layer includes a touch film layer. The display panel of the display device in this application embodiment has touch functionality, which can improve the ease of operation, user experience, integration, and other performance aspects. However, the performance of the display device with touch functionality needs further improvement.

[0070] Please refer to the following: Figure 1 , Figure 2 and Figure 3 For example, in related technologies, display panels need to have holes made in the display (Active Area, AA) area due to reasons such as fingerprint on display (FOD) and ambient light transmission.

[0071] Understandably, in related technologies, the driving device layer 200 can transmit various signals. For example, the driving device layer 200 can be electrically connected to the light-emitting element 500 to provide signals 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 sequentially disposed therefrom. 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 (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 multiple insulating film layers and multiple stacked and mutually insulated first metal layer (M1), second metal layer (M2), metal oxide layer (GATO), third metal layer (M3), and fourth metal layer (M4). The first metal layer, second metal layer, metal oxide layer, third metal layer, and fourth metal layer are sequentially disposed in a direction away from the substrate 100. The multiple insulating film layers are, respectively, a first gate dielectric layer (Gate Insulator 1, GL1), a capacitor dielectric layer (CI), a buffer layer, a second gate dielectric layer (Gate Insulator 1, GL2), an interlayer dielectric layer (ILD), a first planarization layer (Planarization 1, PLN1), and a second planarization layer (Planarization 2, PLN2) sequentially disposed 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] The first metal layer is disposed between the first gate dielectric layer and the capacitor dielectric layer, the second metal layer is disposed between the capacitor dielectric layer and the buffer layer, the metal oxide layer is disposed between the second gate dielectric layer and the interlayer dielectric layer, the third metal layer is disposed between the interlayer dielectric layer and the first planarization layer, and the fourth metal layer is disposed between the first planarization layer and the second planarization layer.

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

[0076] When there is an opening in the display area, the signal transmitted by the drive device layer 200 can easily pass through the opening in the display area and interfere with the signal of the touch trace 800, thus adversely affecting the touch performance.

[0077] Please refer to the following: Figure 4 , Figure 5 and Figure 6 To address the aforementioned technical problems, this application provides a display panel including a substrate 100, a driving device layer 200, and an isolation structure 300. The driving device layer 200 is disposed on one side of the substrate 100 in the thickness direction, and the isolation structure 300 is disposed 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. The light-emitting element 500 is disposed within the isolation opening 310. The light-transmitting opening 320 is used for ambient light transmission or fingerprint always-on display. For example, the isolation structure 300 defines a first isolation opening 311 and a first light-transmitting opening 321, which are spaced apart.

[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 disposed sequentially 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 this embodiment also includes a touch trace 800, which is located on the side of the isolation structure 300 facing away from the substrate 100. The touch trace 800 includes a first trace segment 810 and a second trace segment 820 connected together. The orthographic projection of the first trace segment 810 on the substrate 100 is spaced apart from the orthographic projection of the first isolation opening 311 on the substrate 100, thus preventing the first trace segment 810 from affecting the light emission effect at the first light-transmitting opening 321. The orthographic projection of the second trace segment 820 on the substrate 100 passes through the orthographic projection of the first isolation opening 311 on the substrate 100, allowing the second trace segment 820 to avoid the first light-transmitting opening 321.

[0081] In this way, the display panel provided in this application embodiment can 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 line 800, which is beneficial to improving the touch performance of the display device and thus improving the performance of the display device.

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

[0083] Optionally, the orthographic projection of the first trace 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 trace segment 810 can avoid the first light-transmitting opening 321.

[0084] It is understood that the first encapsulation layer 610, the second encapsulation layer 620, and the third encapsulation layer 630 are located between the touch trace 800 and the isolation structure 300, that is, the touch trace 800 is located on the side of the third encapsulation layer 630 facing away from the substrate 100. The touch trace 800 is typically divided into two layers, including a first layer trace 801 and a second layer trace 802. The third encapsulation layer 630 has an insulating layer 700 on the side facing away from the substrate 100, and the insulating layer 700 is located between the first layer trace 801 and the second layer trace 802.

[0085] Please continue reading. Figure 4 and Figure 5 In some embodiments, the orthographic projection (not shown) of the first isolation opening 311 onto the substrate 100 has a first projection portion, a second projection portion, and a third projection portion, the first projection portion, the second projection portion, and the third projection portion being along a first direction (e.g., Figure 4 The Y-direction in the middle is arranged sequentially, with the first direction perpendicular to the routing direction of the second routing segment 820 (e.g., Figure 4 (in the X direction).

[0086] In the routing direction of the second trace 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 trace segment 820 on the substrate 100. That is to say, the size of the first isolation opening 311 in the routing direction of the second trace segment 820 first decreases and then increases along the first direction.

[0087] In this way, with the width of the second trace segment 820 (the size of the second trace segment 820 in the Y direction) remaining unchanged, compared with the first projection portion and the third projection portion, the second projection portion coincides with the orthographic projection of the second trace 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 emission effect.

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

[0089] For example, the orthographic projection of the protrusion 330 on the substrate 100 coincides with the orthographic projection of the second trace segment 820 on the substrate 100.

[0090] For example, the orthographic projection of the protrusion 330 on the substrate 100 lies within the orthographic projection of the second trace segment 820 on the substrate 100.

[0091] For example, the orthographic projection of the second trace segment 820 on the substrate 100 is located between the two opposite sides of the protrusion 330 in the first direction. That is, the width of the second trace segment 820 is smaller than the dimension of the protrusion 330 in the first direction. In this way, the second trace segment 820 is located at the middle position of the first isolation opening 311 in the first direction, so that the distance between the second trace segment 820 and the two opposite sides of the first isolation opening 311 in the first direction is equal, thereby avoiding the spacing between the second trace segment 820 and the first light-transmitting opening 321 being too small to a certain extent.

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

[0093] It should be noted that the spacing distance is the distance between the adjacent sides of two spaced-apart structures. For example, if a first structure and a second structure are spaced apart, the spacing distance between the first structure and the second structure is the distance between the side of the first structure closest to the second structure and the side of the second structure closest 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] This arrangement of the second trace segment 820 avoids the first light-transmitting opening 321, thereby preventing the signal from the driving device layer 200 from interfering with the signal of the touch trace 800 by passing through the first light-transmitting opening 321. This is beneficial to improving the touch performance of the display device and thus enhancing the overall performance of the display device.

[0096] For example, 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] For example, 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] For example, in the first direction, the first light-transmitting opening and the first isolation opening 311 are arranged alternately. That is, 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 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.

[0099] In this way, in the display panel provided in this 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 opening.

[0100] For example, the orthographic projection of the second trace segment 820 on the substrate 100 is equal to the distance between the orthographic projections of the two adjacent first light-transmitting openings 321 on the substrate 100. In other words, the distance between the orthographic projection of the second trace 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 trace 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 distance between the second trace segment 820 and the first light-transmitting opening 321 is greater than half the size of the first isolation opening 311 in the first direction. This can, to a certain extent, prevent the signal of the driving device layer 200 from interfering with the signal of the touch trace 800 by passing through the first light-transmitting opening 321. This is beneficial to improving the touch performance of the display device and thus improving the performance of the display device.

[0102] Please see 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 trace 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 trace 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] For example, the routing direction of the second trace segment 820 is perpendicular to the spacing direction between the first light-emitting area 3111 and the second light-emitting area 3112. For example, the spacing direction between the first light-emitting area 3111 and the second light-emitting area 3112 is a first direction.

[0105] For example, the distance between the orthographic projection of the second trace 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 distance between the orthographic projection of the second trace 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 distance between the second trace segment 820 and the first light-transmitting opening 321 is greater than half the size of the first isolation opening 311 in the first direction. This can, to a certain extent, prevent the signal from the driving device layer 200 from interfering with the signal of the touch trace 800 through the first light-transmitting opening 321, which is beneficial to improving the touch performance of the display device and thus enhancing the overall performance of the display device.

[0106] In some embodiments, the display panel provided in this application further includes a pixel definition layer 400, which 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-apart pixel openings 401. The orthographic projection of the two pixel openings 401 on the substrate 100 is 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, and the other of the two pixel openings 401 corresponds to the second light-emitting area 3112. The orthographic projection of the second trace 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 orthogonal projection of the pixel opening onto the substrate can avoid the orthogonal projection of the second trace onto the substrate, thereby preventing the second trace from affecting 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, the orthographic projection of the first trace segment 810 on the substrate 100 is located between the orthographic projections of the two adjacent isolation openings 310 on the substrate 100, and the first trace segment 810 and the two adjacent isolation openings 310 are spaced at equal distances.

[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 trace 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 opposite side of the orthographic projection of the first trace segment 810 on the substrate 100.

[0112] Furthermore, the orthographic projection of the first trace segment 810 on the substrate 100 is equidistant from the orthographic projections of the two adjacent isolation openings 310 on the substrate 100. In other words, the distance between the orthographic projection of one of the two adjacent isolation openings 310 on the substrate 100 and the orthographic projection of the first trace segment 810 on the substrate 100 is equal to the distance between the orthographic projection of the other of the two adjacent isolation openings 310 on the substrate 100 and the orthographic projection of the first trace segment 810 on the substrate 100.

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

[0114] In this way, the spacing between the first trace segment 810 and the two adjacent isolation openings 310 is equal, which can, to some extent, prevent the spacing between the first trace segment 810 and the isolation opening 310 from being too small. It can be understood that with the isolation openings 310 and the light-transmitting openings 320 arranged alternately, increasing the spacing between the first trace segment 810 and the isolation openings 310 will also increase the spacing between the first trace segment 810 and the light-transmitting openings 320 to some extent, thereby preventing the signals from the driving device layer 200 from interfering with the signals of the touch trace 800 by passing through the first light-transmitting opening 321.

[0115] It is understood that the light-emitting element 500 (first light-emitting element) corresponding to the first isolation opening 311 can emit the first type of 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 type of 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 type of blue light, red light, and green light.

[0116] Exemplarily, the display panel provided in this application embodiment 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 the 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 the 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 the green (G) pixel.

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

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

[0119] For example, the first wiring segment 810 surrounds the second isolation opening 312.

[0120] For example, the first wiring segment 810 surrounds the third isolation opening 313.

[0121] For example, the first wiring 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 the area enclosed by the orthographic projection of the first trace 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 line segment 810 bypasses the second isolation opening 312 and the third isolation opening 313, avoiding blocking the second isolation opening 312 and the third isolation opening 313, which helps to improve the light-emitting effect.

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

[0125] For example, two adjacent isolation openings 310 are spaced apart in a 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 the 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 the area enclosed by the orthographic projection of the first trace segment 810 on the substrate 100.

[0127] In other words, the orthographic projections of the adjacent second isolation opening 312 and third isolation opening 313 onto the substrate 100 are located within the area enclosed by the orthographic projection of the first trace segment 810 onto the substrate 100. Furthermore, the orthographic projection of the second light-transmitting opening 322 onto the substrate 100 is located within the area enclosed by the orthographic projection of the first trace segment 810 onto 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] For example, in the first direction, the second isolation opening 312 and the third isolation opening 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 trace segment 810 bypasses the second isolation opening 312 and the third isolation opening 313, thus avoiding obstruction of the second isolation opening 312 and the third isolation opening 313. In addition, the first trace segment 810 bypasses the second light-transmitting opening 322, which can also prevent the signal of the driving device layer 200 from interfering with the signal of the touch trace 800 by passing through the second light-transmitting opening 322.

[0130] Please continue reading. Figure 4 , Figure 6 and Figure 7 In some embodiments, the display panel provided in this 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 201. The anode of the first light-emitting element extends into the first via 201, and the orthographic projection of the second trace segment 820 on the substrate 100 overlaps with the orthographic projection of the first via 201 on the substrate 100. At least a portion of the orthographic projection of the first via 201 on the substrate 100 lies within the orthographic projection of the protrusion 330 on the substrate 100.

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

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

[0133] For example, the second trace segment 820 covers the first via 201. That is, the orthogonal projection of the first via 201 on the substrate 100 lies within the orthogonal projection of the second trace segment 820 on the substrate 100.

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

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

[0136] In this way, the first via 201 avoids the first isolation opening 311. Furthermore, with the width of the second trace segment 820 (the size of the second trace segment 820 in the Y direction) remaining unchanged, compared with the first projection portion and the third projection portion, the orthographic projection of the second trace 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, thus improving the light emission effect.

[0137] In some embodiments, the display panel provided in this 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. The orthogonal 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] Furthermore, the display panel provided in this application embodiment also 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 202. The anodes of the second light-emitting element and the anodes of the third light-emitting element extend into different second vias 202.

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

[0140] Please participate Figure 8 In some embodiments, the touch trace 800 further includes a third trace segment 830, the orthographic projection of the third trace segment 830 on the substrate 100 being located within the area enclosed by the orthographic projection of the first trace segment 810 on the substrate 100, and the trace direction of the third trace segment 830 (e.g., Figure 9 The X direction in the diagram 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 trace segment 830 passes through the second light-transmitting opening 322, the display panel provided in this application embodiment can, to a certain extent, prevent the signal of the driving device layer 200 from interfering with the signal of the touch trace 800 by passing through the second light-transmitting opening 322.

[0142] Exemplarily, a portion of the orthographic projection of the third trace segment 830 on the substrate 100 lies 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 trace segment 830 on the substrate 100 lies between the third isolation opening 313 and the second light-transmitting opening 322. Exemplarily, some portions of the orthographic projection of the third trace segment 830 on the substrate 100 lie 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 trace segment 830 on the substrate 100 lie 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 trace segment 830 on the substrate 100 lies 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 portion of the orthographic projection of the third trace segment 830 on the substrate 100 coincides 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, the second isolation opening 312, or the third isolation opening 313 that is blocked.

[0144] Please see Figure 9 In some other embodiments, unlike the embodiments described above, the third trace segment 830 is connected to the first trace segment 810 and / or the second trace segment 820, which can increase the trace density of the touch trace 800 and help improve the touch performance to a certain extent.

[0145] For example, a portion of the orthographic projection of the third trace 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 portion of the orthographic projection of the third trace segment 830 on the substrate 100 coincides with the orthographic projection of the second light-transmitting opening 322 on the substrate 100.

[0146] For example, a portion of the orthographic projection of the third trace 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 portion of the orthographic projection of the third trace segment 830 on the substrate 100 coincides with the orthographic projection of the second light-transmitting opening 322 on the substrate 100.

[0147] This reduces the area of ​​the second light-transmitting opening 322 from being blocked, and does not block the second isolation opening 312 and the third isolation opening 313. It 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 line 800 to a certain extent.

[0148] For example, a portion of the orthographic projection of the third trace 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 portion of the orthographic projection of the third trace segment 830 on the substrate 100 coincides with the orthographic projection of the second isolation opening 312 on the substrate 100.

[0149] For example, a portion of the orthographic projection of the third trace 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 portion of the orthographic projection of the third trace segment 830 on the substrate 100 coincides with the orthographic projection of the third isolation opening 313 on the substrate 100.

[0150] This reduces the area of ​​the second light-transmitting opening 322 without obstructing it, thereby reducing the interference of the signal from the driving device layer 200 passing through the second light-transmitting opening 322 on the signal of the touch trace 800 to a certain extent.

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

[0152] For example, the shielding layer is disposed in the same layer as the cathode of the second light-emitting element.

[0153] For example, the shielding layer is disposed in the same layer as the cathode of the third light-emitting element.

[0154] For example, the shielding layer is disposed in the same layer as the cathodes of the second and third light-emitting elements.

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

[0156] Please continue reading. Figure 9 In some embodiments, the touch trace 800 further includes a third trace segment 830, the orthographic projection of the third trace segment 830 on the substrate 100 is located within the area enclosed by the orthographic projection of the first trace segment 810 on the substrate 100, and the trace direction of the third trace segment 830 is perpendicular to the first direction.

[0157] For example, the routing direction of the third routing segment 830 is the same as that of the second routing segment 820.

[0158] Optionally, the third trace segment 830 is connected to the first trace segment 810. In the trace direction of the third trace segment 830, the third trace segment 830 includes a first segment 831 and a second segment 832 disposed 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.

[0159] like Figure 9 As shown, in the extension direction of the second trace segment 820, one end of the second trace segment 820 is connected to the first segment 831 of a third trace segment 830, and the other end of the second trace segment 820 is connected to the second segment 832 of another third trace segment 830; the second trace segment 820 includes a target trace segment 8201, the first segment 831 of the third trace segment 830 connected to the target trace segment 8201, the second segment 832 of another third trace segment 830 connected to the target trace segment 8201, and the target trace segment 8201 are disposed on the same layer and form a bridging part; in the extension direction of the second trace segment 820, the touch traces 800 located at both ends of the bridging part are connected through the bridging part; in the first direction ( Figure 9 In the Y direction, the orthographic projection of the bridging portion on the substrate 100 is 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.

[0160] It is understood that the first segment 831 and the second segment 832 are connected to form at least a portion of the third trace segment 830, and the orthographic projection of at least a portion of the third trace segment 830 on the substrate 100 lies 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 trace segment 830 avoids the second isolation opening 312 and the third isolation opening 313, thus avoiding affecting the light emission effect at the second isolation opening 312 and the third isolation opening 313.

[0161] For example, the first segment and the second segment are connected by a wire-changing hole, and the orthographic projection of the wire-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.

[0162] This application provides another display panel, including a substrate 100, a driving device layer 200, an isolation structure 300 and a touch trace 800. The driving device layer 200 is disposed on one side of the substrate 100 in the thickness direction, and the isolation structure 300 is disposed on the side of the driving device layer 200 away from the substrate 100.

[0163] The isolation structure 300 defines a first isolation opening 311, a second isolation opening 312, a third isolation opening 313, and a first light-transmitting opening 321, which are spaced apart from the first isolation opening 311, the second isolation opening 312, and the third isolation opening 313.

[0164] The touch trace 800 is located on the side of the isolation structure 300 facing away from the substrate 100. The touch trace 800 includes a connected first trace segment 810 and a second trace segment 820. The first trace segment 810 has a second isolation opening 312 and / or a third isolation opening 313, which prevents the first trace segment 810 from affecting the light-emitting effect at the second isolation opening 312 and / or the third isolation opening 313. The orthogonal projection of the second trace segment 820 onto the substrate 100 passes through the orthogonal projection of the first isolation opening 311 onto the substrate 100, allowing the second trace segment 820 to avoid the first light-transmitting opening 321.

[0165] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
