DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; and "inside" and "outside" refer to the outline of the device.

[0035] The present application provides a display panel, such as Figures 1 to 3 As shown, the display panel includes a plane portion A1 and a curved portion S0 arranged on the periphery of the plane portion A1, the curved portion S0 includes a first curved portion S1, a second curved portion S2 and a corner portion S3 arranged between the first curved portion S1 and the second curved portion S2, the display panel includes a substrate 10, an encapsulation layer 20, a first wiring layer 30, and a second wiring layer 40, the encapsulation layer 20 is arranged on one side of the substrate 10; the first wiring layer 30 is arranged on the side of the encapsulation layer 20 away from the substrate 10, and the first wiring layer 30 includes The substrate 10 and the packaging layer 20 include a plurality of first routing lines 31, wherein a first routing line 31 includes a first sub-line 311 arranged corresponding to the first curved portion S1 and a second sub-line 312 arranged corresponding to the second curved portion S2; a second routing layer 40 is arranged between the substrate 10 and the packaging layer 20, and the second routing layer 40 includes a plurality of second routing lines 41, and the second routing lines 41 are arranged corresponding to the corner S3; wherein one end of a second routing line 41 is electrically connected to the first sub-line 311, and the other end is electrically connected to the second sub-line 312.

[0036] In this embodiment, the display panel may be an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0037] In this embodiment, the substrate 10 may be a flexible substrate, and the material of the flexible substrate may be one of colorless polyimide (PI), polycarbonate (PC), polynorbornene (PNB), polyethylene terephthalate (PET), and the like.

[0038] In this embodiment, if Figure 1 and Figure 2 As shown, the display panel may be a curved display panel, for example, a three-curved display panel, a four-curved display panel, etc. The display panel includes a plane portion A1 and a curved display portion disposed on at least one side of the plane portion A1. The display surface of the plane portion A1 is a plane, and the display surface of the curved display portion is a curved surface. The curved display portion is disposed on at least two sides of the plane portion A1, wherein the first curved portion S1 and the second curved portion S2 are adjacent. The curved display portion also includes a corner portion S3, which corresponds to a corner of the display panel, and the corner portion S3 is adjacent to the first curved portion S1 and the second curved portion S2.

[0039] like Figure 2 As shown, the display panel includes a display layer 70, which is arranged on one side of the substrate 10. The display layer 70 includes a plurality of light-emitting units, which may be red light-emitting units, green light-emitting units, and blue light-emitting units, and the light-emitting units may realize picture display.

[0040] In this embodiment, if Figure 2 As shown, the encapsulation layer 20 is disposed on the side of the display layer 70 away from the substrate 10 , and the encapsulation layer 20 is used to encapsulate and protect the display layer 70 to prevent water vapor and the like from entering the display layer 70 and affecting the life of the light-emitting unit.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, the first wiring layer 30 is disposed on a side of the packaging layer 20 away from the substrate 10 , and the second wiring layer 40 is disposed on a side of the packaging layer 20 close to the substrate 10 .

[0042] The first routing layer 30 includes a plurality of first routing lines 31, and the first routing lines 31 include a first sub-line 311 corresponding to the first curved surface S1 and a second sub-line 312 corresponding to the second curved surface S2, that is, part of the first routing line 31 can be disconnected at the corner S3, and the two disconnected parts are the first sub-line 311 and the second sub-line 312. The first routing line 31 can be a straight line, a curve, etc., but is not limited thereto.

[0043] The second routing layer 40 includes a plurality of second routing lines 41, which are arranged corresponding to the corner S3, and one end of the second routing line 41 is connected to the first sub-line 311, and the other end is connected to the second sub-line 312. That is to say, the disconnected first sub-line 311 and the second sub-line 312 of the first routing line 31 can be connected via the second routing line 41.

[0044] The second straight line may be a straight line, a curve, etc., but is not limited thereto.

[0045] Since the film layer at the corner S3 is a curved surface, and the film layer is subjected to pressure and / or tension from the first curved surface S1 and the second curved surface S2, the film layer at the corner S3 is subjected to greater stress, and the film layer is prone to peeling or rupture. The closer to the surface of the display panel, the greater the radius of curvature of the film layer at the corner S3, the greater the stress it is subjected to, and the more likely it is to peel or rupture. By switching the first wiring 31 at the corner S3 to a film layer closer to the substrate 10, the stress on the second wiring 41 can be reduced, the risk of peeling or rupture of the second wiring layer 40 at the corner S3 can be reduced, and the quality reliability of the display panel can be improved.

[0046] It should be understood that if Figure 3 As shown, the first sub-line 311 can be connected to one end of the second routing line 41 through a via hole, and the second sub-line 312 can also be connected to the other end of the second routing line 41 through a via hole. In order to realize the connection between the first sub-line 311 and the second routing line 41 through the via hole, the end of the first sub-line 311 can partially overlap with the end of the second routing line 41 at the boundary between the first curved surface S1 and the corner S3, and the end of the second sub-line 312 can partially overlap with the end of the second routing line 41 at the boundary between the second curved surface S2 and the corner S3.

[0047] In this embodiment, if Figure 2 As shown, the display panel may further include a polarizer 80 and a cover plate 90. The polarizer 80 is disposed on the side of the first wiring layer 30 away from the substrate 10, and the cover plate 90 is disposed on the side of the polarizer 80 away from the substrate 10. The material of the cover plate 90 may be a flexible material such as polyimide, so that the display device has good bending performance. The cover plate 90 may protect the film layer inside the display panel.

[0048] In the display panel of the present application, Figure 1 As shown, the extension direction of the second wiring 41 is not parallel to the extension direction of the first curved surface S1 , and the extension direction of the second wiring 41 is not parallel to the extension direction of the second curved surface S2 .

[0049] In this embodiment, the first curved surface S1 may extend along the first direction D1, and the second curved surface S2 may extend along the second direction D2, and the first direction D1 and the second direction D2 are arranged at an angle, which may be an acute angle, a right angle, or an obtuse angle.

[0050] The corner portion S3 is connected to the first curved surface portion S1 and the second curved surface portion S2 , and a contour line of the corner portion S3 away from the center of the display panel may be a straight line or a curve.

[0051] The inventors of the present application found that when the extension direction of the second wiring 41 is the same as the extension direction of the first curved surface S1, or when the extension direction of the second wiring 41 is the same as the extension direction of the second curved surface S2, the second wiring 41 is subjected to greater stress and is more prone to rupture.

[0052] To address this, in this embodiment, the extension direction of the second wiring 41 is set to be non-parallel to the first direction D1 and the second direction D2, thereby reducing the stress on the second wiring 41 and further reducing the risk of the second wiring 41 breaking.

[0053] Furthermore, in this embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the second line 41 includes a plurality of sub-line segments 300 connected in sequence, and the sub-line segments 300 are straight line segments or curved line segments.

[0054] Optionally, in some embodiments, Figure 4 As shown, the plurality of sub-segments 300 can all be straight line segments, and two adjacent straight line segments are connected to form a sawtooth-like shape. It should be noted that any straight line segment is not parallel to the first direction D1 or the second direction D2. Through the above arrangement, the extension direction of the sub-segment 300 can be staggered with the stress direction, thereby further reducing the stress on the sub-segment 300 and further reducing the risk of the second wiring 41 breaking.

[0055] Optionally, in some embodiments, Figure 5 As shown, the plurality of sub-segments 300 can all be curved segments, and two adjacent curved segments are connected to form a shape similar to a wave line. Through the above arrangement, the extension direction of the sub-segment 300 can be staggered with the stress direction, thereby further reducing the stress on the sub-segment 300 and further reducing the risk of the second wiring 41 breaking.

[0056] Optionally, in some embodiments, some sub-segments 300 may be straight segments, and other sub-segments 300 may be curved segments, and the straight segments and the curved segments may be arranged alternately. Through the above arrangement, the extension direction of the sub-segments 300 and the stress direction can be staggered, thereby further reducing the stress on the sub-segments 300 and further reducing the risk of the second routing line 41 being broken.

[0057] In the display panel of the present application, Figure 6As shown, at least one first routing line 31 includes a third sub-line 313 arranged corresponding to the corner S3, one end of the third sub-line 313 is connected to a first sub-line 311, and the other end is connected to a second sub-line 312; wherein, the orthographic projection of at least one second routing line 41 on the substrate 10 is located on a side of the orthographic projection of the third sub-line 313 on the substrate 10 away from the center of the substrate 10.

[0058] In this embodiment, part of the first wiring 31 includes a first sub-line 311, a third sub-line 313, and a second sub-line 312 that are sequentially connected, that is, the first wiring 31 is continuously arranged in the first curved portion S1, the corner portion S3, and the second curved portion S2. Another part of the first wiring 31 includes a disconnected first sub-line 311 and a second sub-line 312, and the first sub-line 311 and the second sub-line 312 are connected through a second wiring 41 of a different layer.

[0059] The orthographic projection of the second routing line 41 on the substrate 10 is located on the side of the orthographic projection of the third sub-line 313 on the substrate 10 away from the center of the substrate 10, that is, the orthographic projection of the second routing line 41 on the substrate 10 is located outside the orthographic projection of the third sub-line 313 on the substrate 10.

[0060] At the corner S3, the stress on the film layer far from the center of the substrate 10 is greater than the stress on the film layer near the center of the substrate 10. Therefore, the wiring far from the center of the substrate 10 can be arranged in the second wiring layer 40 closer to the substrate 10, thereby reducing the stress on the wiring outside the corner S3. In addition, since the third sub-wires 313 of some first wirings 31 can still be arranged in the first wiring layer 30, the number of second wirings 41 can be reduced, the occupied space of the second wirings 41 in the second wiring layer 40 is reduced, and the wiring difficulty of the second wirings 41 in the second wiring layer 40 is reduced.

[0061] Furthermore, in this embodiment, the third sub-line 313 includes a plurality of sub-line segments 300 connected in sequence, and the sub-line segments 300 are straight line segments or curve segments; the orthographic projection of at least one third sub-line 313 on the substrate 10 is located between the orthographic projections of two adjacent second routing lines 41 on the substrate 10.

[0062] The third sub-line 313 may include a plurality of sub-line segments 300 connected in sequence. The arrangement of the sub-line segments 300 may refer to the arrangement of the sub-line segments 300 of the second routing line 41 , which will not be repeated here.

[0063] In this embodiment, if Figure 6As shown, the orthographic projection of part of the third sub-line 313 on the substrate 10 can be located between the orthographic projections of two adjacent second routing lines 41 on the substrate 10, that is, in the orthographic projection pattern on the substrate 10, the third sub-line 313 and the second routing line 41 can be arranged alternately. Through the above arrangement, the distribution density of the third sub-line 313 can be reduced, the stress concentration degree of the third sub-line 313 at the corner S3 can be reduced, and the risk of the third sub-line 313 being broken can be reduced.

[0064] Further, in the display panel of the present application, the ratio of the thickness of the third sub-line 313 to the width of the third sub-line 313 is less than or equal to the ratio of the thickness of the second wiring 41 to the width of the second wiring 41 .

[0065] The thickness of the trace refers to the size of the trace in the direction perpendicular to the display surface. The width of the trace refers to the size of the short side of the trace in the direction parallel to the display surface.

[0066] When the bending radius of the routing is the same, when the thickness of the routing is thicker, the difference in stress on the two side surfaces of the routing in the thickness direction is greater, resulting in greater stress on the routing. Therefore, reducing the thickness of the routing is conducive to reducing the stress on the routing. By reducing the ratio of the thickness of the third sub-line 313 to the width of the third sub-line 313, it is conducive to reducing the stress on the third sub-line 313. At the same time, in order to avoid the impedance change of the third sub-line 313 caused by the reduction of the thickness of the third sub-line 313, the width of the third sub-line 313 can be increased, thereby reducing the influence of the reduction of the thickness of the third sub-line 313 on the impedance of the third sub-line 313.

[0067] In the display panel of the present application, Figure 2 As shown, the display panel includes an array layer 50 and a shielding layer 60, the array layer 50 is arranged between the substrate 10 and the packaging layer 20, and the shielding layer 60 is arranged between the array layer 50 and the substrate 10; the array layer 50 includes a thin film transistor 51, and the thin film transistor 51 includes a source and drain electrode 511 and a gate electrode 512; wherein any one of the source and drain electrode 511, the gate electrode 512, and the shielding layer 60 is arranged on the same layer as the second wiring layer 40.

[0068] In this embodiment, if Figure 2 As shown, the shielding layer 60 is disposed on one side of the substrate 10, the array layer 50 is disposed on the side of the shielding layer 60 away from the substrate 10, and the display layer 70 is disposed on the side of the array layer 50 away from the substrate 10. The array layer 50 includes a thin film transistor 51, etc. The thin film transistor 51 can be connected to the light-emitting unit of the display layer 70 to provide a driving signal for the light-emitting unit.

[0069] The thin film transistor 51 includes a source-drain electrode 511, and the source-drain electrode 511 includes a source electrode and a drain electrode. Specifically, the light-emitting unit may include a stacked anode 71, a light-emitting layer 72, and a cathode 73, wherein the anode 71 is used to provide holes, and the cathode 73 is used to provide electrons, and the holes and electrons are recombined in the light-emitting layer 72 to emit light. The drain electrode of the thin film transistor 51 may be electrically connected to the anode 71, thereby providing a driving voltage to the anode 71. The source electrode of the thin film transistor 51 may be connected to a driving signal.

[0070] In this embodiment, the material of the source and drain 511, the gate 512, and the shielding layer 60 can be metal, such as any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu), or their alloys.

[0071] The second wiring layer 40 may be disposed on the same layer as any one of the source and drain electrodes 511 , the gate electrode 512 , and the shielding layer 60 . Figure 2 The second wiring layer 40 is shown as being disposed on the same layer as the source and drain electrodes 511. When the second wiring layer 40 is disposed on the same layer as one of the source and drain electrodes 511, the gate electrode 512, and the shielding layer 60, the material of the second wiring 41 can be made of the same material as the metal of the layer, so that the second wiring 41 can be manufactured using the same process, thereby avoiding adding process steps for the display panel.

[0072] In some embodiments, Figure 3 As shown, Figure 3 Shows Figure 1 A schematic diagram of the cross-sectional structure of the curved portion S0 and the flat portion A1 of a display panel. The second wiring layer 40 can be arranged at the same layer as the shielding layer 60. The shielding layer 60 can be arranged below the thin film transistor 51, that is, the orthographic projection of the shielding layer 60 on the substrate 10 can overlap with the orthographic projection of the thin film transistor 51 on the substrate 10. The shielding layer 60 can be connected to a constant voltage to prevent the surrounding interference signals from affecting the thin film transistor 51, thereby effectively improving the reliability of the circuit.

[0073] Since the shielding layer 60 can be arranged corresponding to the thin film transistor 51 , the redundant space between the patterns of the shielding layer 60 in the curved surface area S0 is larger, which is more conducive to the arrangement of the second wiring 41 .

[0074] The material of the shielding layer 60 may include a transparent conductive oxide, for example, a conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium gallium oxide (IGO), or aluminum zinc oxide (AZO).

[0075] It should be understood that the second wiring layer 40 may also be made of other metal layers between the packaging layer 20 and the substrate 10 , and the present application does not impose any limitation on this.

[0076] In the display panel of the present application, Figure 2 As shown, the encapsulation layer 20 includes at least one inorganic layer 21 and at least one organic layer 22 stacked, and the encapsulation layer 20 can prevent water vapor and the like from invading the interior of the display panel and affecting the life of the light-emitting unit. The thickness of the encapsulation layer 20 at the corner S3 is less than or equal to the thickness of the encapsulation layer 20 at the first curved portion S1, and the thickness of the encapsulation layer 20 at the corner S3 is less than or equal to the thickness of the encapsulation layer 20 at the second curved portion S2.

[0077] In this embodiment, the inorganic layer 21 may be a single layer or multiple layers of metal oxide or metal nitride, for example, silicon nitride, aluminum oxide, silicon oxide, etc. The organic layer 22 may be a single layer or multiple layers formed of any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate, etc. Optionally, multiple layers of inorganic layers 21 may be alternately arranged with multiple layers of organic layers 22.

[0078] In this embodiment, the thickness of the encapsulation layer 20 at the corner S3 can be less than or equal to the thickness of the encapsulation layer 20 at the first curved portion S1, and the thickness of the dissected encapsulation layer 20 can be less than or equal to the thickness of the encapsulation layer 20 at the second curved portion S2. Through the above settings, the thickness of the encapsulation layer 20 at the corner S3 can be thinned, thereby reducing the stress inside the film layer of the corner S3.

[0079] Optionally, the thickness of the encapsulation layer 20 at the corner portion S3 may be greater than or equal to the thickness of the encapsulation layer 20 at the plane portion A1 , thereby ensuring the encapsulation effect of the encapsulation layer 20 at the corner portion S3 .

[0080] In the display panel of the present application, Figure 2 As shown, the first wiring layer 30 includes a touch wiring layer. That is to say, the display panel can be a packaged touch integrated (Direct on-cell touch, DOT) panel, and there is no need to add a separate external touch layer, thereby effectively reducing the thickness of the display panel and reducing product costs.

[0081] like Figure 1 and Figure 2 As shown, the display panel includes a plurality of touch electrodes 100 , and the first wiring 31 is a touch wiring connected to the touch electrodes 100 .

[0082] The present application also provides a display terminal, which includes the above-mentioned display panel.
