(9) A display panel, a method for manufacturing a display panel, and a display device provided in the embodiments of the present disclosure are described in detail below respectively.

(10) Referring to FIGS. 1 to 3, the embodiments of the present disclosure provide a display panel, including a substrate 10, a line layer 20, and a conducting layer 30.

(11) The substrate 10 may be a rigid substrate or a flexible substrate. For example, the substrate 10 may be a glass substrate or a polyimide (PI) substrate.

(12) The substrate 10 includes a first surface 101 and a second surface 102 facing away from each other. A first edge 110 of the substrate 10 may be an edge extending in a first direction X. A plurality of first protruding portions 11 are disposed on the first edge 110, and two adjacent first protruding portions 11 are spaced apart from each other. For example, the first surface 101 may be a front side of the substrate 10, and the second surface 102 may be a back side of the substrate 10. The first protruding portion 11 may be formed by cutting or etching the substrate 10. That is to say, the first protruding portion 11 and the substrate 10 are integrally formed, so that a manufacturing process can be simplified while guaranteeing the structural strength. In detail, an etching process may be, for example, laser cutting, wet etching, or the like. This is not limited in detail herein.

(13) The line layer 20 includes a plurality of first traces 201 and a plurality of second traces 202 that extend in a second direction Y. The first traces 201 are disposed on the first surface 101. The second traces 202 are disposed on the second surface 102. Each of the first traces 201 and each of the second traces 202 respectively extend to one of the first protruding portions 11. Correspondingly, the first traces 201 are traces disposed on the front side of the substrate 10, and the second traces 202 are traces disposed on the back side of the substrate 10.

(14) The first trace 201 or the second trace 202 can extend to an edge of the first protruding portion 11 or any position inside the first protruding portion 11 when extending to the first protruding portion 11, which is not limited in detail herein in the present embodiment.

(15) In addition, the first trace 201 and the second trace 202 may extend in a same direction on the first surface 101 and the second surface 102 respectively. The first trace 201 may extend in a straight line, in a curve, or in both the straight line and the curve. Similarly, the second trace 202 may extend in a straight line, in a curve, or in both the straight line and the curve.

(16) For example, the first edge 110 extends in the first direction X. The plurality of first traces 201 and the plurality of second traces 202 extend in the second direction Y. The second direction Y intersects with the first direction X. The second direction Y and the first direction X may be perpendicular to each other. By taking a rectangular plane coordinate system as an example, the first direction may be an X-axis direction, and the second direction is a Y-axis direction. It is to be noted that, perpendicular refers to a state that an angle formed by two straight lines is above 800 and below 100. Therefore, a state of an angle of above 850 and below 950 is also included.

(17) The conducting layer 30 is disposed on the first protruding portion 11 and covers the first protruding portion 11. The conducting layer 30 may be printed on the first protruding portion 11 by printing, so that the first trace 201 is connected to the second trace 202 by the conducting layer 30. The conducting layer 30 is made of conductive paste. The conductive paste may be a metal material such as silver paste, solder paste and the like having a conductive function, which is not limited in detail herein.

(18) According to the display panel provided in the present disclosure, the plurality of first protruding portions 11 spaced apart from each other are disposed on the first edge 110 of the substrate 10, so that the first trace 201 located on the first surface 101 of the substrate 10 and the second trace 202 located on the second surface 102 of the substrate 10 respectively extend to the first protruding portion 11. The conducting layer 30 covers the first protruding portion 11 to connect the first trace 201 to the second trace 202. Through the arrangement of the first protruding portion 11, each of the first traces 201 can be separated from each of the second traces 202, thereby avoiding a short circuit between adjacent first traces 201 or a short circuit between adjacent second traces 202 while realizing high-precision line width and line spacing of the traces. Therefore, the yield of the wire printing process can be effectively increased, and a simple process is achieved.

(19) In some embodiments, the substrate 10 further includes a third surface 103. The third surface 103 is formed on an end surface of the first protruding portion 11 away from the first edge 110. The third surface 103 is disposed adjacent to the first surface 101 and the second surface 102. In detail, by taking the first surface 101 as the front side and the second surface 102 as the back side, the third surface 103 is a side surface connecting the front side to the back side. In detail, in the present embodiment, the third surface 103 is the side surface further covered by the conducting layer 30 on the first protruding portion 11, that is to say, the conducting layer 30 further covers the third surface 103. For example, the third surface 103 is a plane formed by the first direction X and a third direction Z. The conducting layer 30 is simultaneously printed on the first surface 101, the second surface 102, and the third surface 103. The conducting layer 30 is printed on three surfaces adjacent to the first protruding portion 11, the conductive paste is in a C-shaped structure, so that the first trace 201 can be connected to the second trace 202. In addition, the first trace 201 can be prevented from being connected to adjacent traces, or the second trace 202 can be prevented from being connected to adjacent traces, thereby preventing the short circuits of the traces.

(20) In some embodiments, as shown in FIG. 2, the substrate 10 further includes a second edge 120. The first edge 110 is disposed opposite to the second edge 120. In detail, the first edge 110 and the second edge 120 are spaced apart from each other in a same direction on the substrate 10. For example, the first edge 110 and the second edge 120 are both disposed in the first direction X, and are spaced apart from each other on the substrate 10.

(21) A plurality of second protruding portions 12 are disposed on the second edge 120, and two adjacent second protruding portions 12 are spaced apart from each other. Two ends of each of the first traces 201 respectively extend to one of the first protruding portions 11 and one of the second protruding portions 12. Two ends of each of the second traces 202 respectively extend to the first protruding portion 11 and the second protruding portion 12. The conducting layer 30 covers the second protruding portion 12. The plurality of first protruding portions 11 and the plurality of second protruding portions 12 may be symmetrically disposed. That is to say, the first protruding portion and the second protruding portion are respectively disposed on two sides of the substrate 10 in a one-to-one correspondence, or may be in a staggered arrangement, which is not limited in detail herein. The protruding portion is disposed on the edges on the two sides of the substrate 10 for trace printing, so as to increase the density of the printed traces, thereby improving the display performance.

(22) In some embodiments, a width by which each of the first protruding portions 11 and/or each of the second protruding portions 12 protrude(s) from the edge of the substrate 10 ranges from 30 microns to 60 microns. In the present embodiment, the width refers to a distance by which the first protruding portion 11 or the second protruding portion 12 protrudes from the edge of the substrate 10 in the second direction Y. By taking the first protruding portion 11 as an example, the width by which the first protruding portion 11 protrudes from the edge of the substrate 10 may be 30 m, 50 m, 60 m, or the like. When a width of the each first trace 201 formed by printing is specified, by setting the width of the first protruding portion 11 to be greater than 30 m, an area of the conducting layer 30 such as the silver paste in contact with the first trace 201 can be increased, preventing the short circuit or bad contact of the traces. In addition, the width of the first protruding portion 11 is set to be less than 60 m, so that when a plurality of display panels are spliced, the area between spliced parts cannot be excessively large, and seam widths of the spliced panel can be decreased, thereby ensuring the aesthetic degree of the display effect.

(23) In some embodiments, the display panel further includes a protective film 40. As shown in FIG. 3, the protective film 40 is wrapped around the first protruding portion 11 along the first surface 101 to the second surface 102. The protective film 40 covers the conducting layer 30. The protective film 40 may be an insulating film made of an organic adhesive material, and is configured to protect the conducting layer 30 printed on the first protruding portion 11 from being damaged in the following process. In detail, the protective film 40 may be a black protective film 40, so that light leakage can be prevented while the conducting layer 30 is protected. It is to be noted that, the protective film 40 may be attached to a side edge of the substrate 10 having the first protruding portion 11 disposed thereon, or may be attached to edges of a plurality of sides of the substrate 10. For example, the protective film is attached to peripheral edges of the substrate 10.

(24) It is to be noted that, the protective film 40 may completely wrap around the conducting layer 30. The protective film 40 may partially cover the edge of the first protruding portion 11, may completely cover the first protruding portion 11, or may partially cover the substrate 10 while partially covering the first protruding portion 11. In the present embodiment, a coverage width of the protective film 40 on the first protruding portion 11 is not limited in detail.

(25) It can be understood that, a plurality of protective films 40 may be disposed. Correspondingly, the protective film 40 may also be disposed on the second protruding portion 12. The protective film 40 is wrapped around the second protruding portion 12 along the first surface 101 to the second surface 102, so that the protective film 40 covers the conducting layer 30 of the second protruding portion 12, and can also have protection and light shielding effects on the trace on the second protruding portion 12.

(26) In some embodiments, referring to FIGS. 2 and 3, the protective film 40 is further wrapped around a gap between two adjacent first protruding portions 11. In detail, a first recess 13 is formed in the gap between the two adjacent first protruding portions 11. The first edge 110 further includes a plurality of first recesses 13, and each of the first recesses 13 is disposed adjacent to each of the first protruding portions 11. The protective film 40 is further wrapped around the first recess 13 and the first protruding portion 11. The protective film 40 is wrapped around the first recess 13 and the first protruding portion 11 simultaneously. That is to say, the protective film 40 covers the gap between the two adjacent first protruding portions 11, so that the whole surface wrapping of the protective film 40 can be realized. Compared with the manner of separately wrapping the each first protruding portion 11, the whole surface wrapping can guarantee a desirable protection effect while simplifying the process.

(27) It may be understood that, the protective film 40 may further wrap around a gap between two adjacent second protruding portions 12. A plurality of second recesses 14 are further disposed on the second edge 120. The second recess 14 and the second protruding portion 12 that are adjacent to each other are spaced apart from each other. The whole surface of the protective film 40 is wrapped around the plurality of second protruding portions 12, so as to prevent the short circuit between the first trace 201 or the second trace 202.

(28) In some embodiments, the edge of the conducting layer 30 is flush with the first edge 110 or located inside the first protruding portion 11. For example, when the conducting layer 30 is in a plane in which the first surface 101 or the second surface 102 is located, the width of the conducting layer 30 does not exceed the width of the first protruding portion 11. The width of the conducting layer 30 is a distance by which the trace extends in the second direction Y. In detail, the width of the conducting layer 30 may be same as the width of the first protruding portion 11. In this case, the edge of the conducting layer 30 is flush with the first edge 110. The width of the conducting layer 30 may also be less than the width of the first protruding portion 11. In this case, the edge of the conducting layer 30 is located inside the first protruding portion 11. The width of the conducting layer 30 is controlled to not exceed the width of the first protruding portion 11, so that the conducting layer 30 is not located in the substrate 10, thereby preventing the conducting layer 30 from coming into contact with the first trace 201 or the second trace 202 in the substrate 10, causing the short circuit between the adjacent first traces 201 or the adjacent second traces 202 in the substrate 10. In this way, the manufacturing yield can be increased.

(29) It may be understood that, the edge of the conducting layer 30 may also be flush with the second edge 120 or located inside the second protruding portion 12. Likewise, the problem, caused by the conducting layer 30, of the short circuit between the adjacent first traces 201 or the adjacent second traces 202 in the substrate 10 may also be avoided, thereby increasing the manufacturing yield.

(30) In order to better implement the display panel in the present disclosure, an embodiment of the present disclosure further provides a method for manufacturing a display panel. As shown in FIG. 4, the method includes steps S101-S103.

(31) S101: Etching a first edge 110 of a substrate 10 to form a plurality of first protruding portions 11.

(32) The first protruding portion 11 may be formed by cutting or etching the substrate 10. That is to say, the first protruding portion 11 and the substrate 10 are integrally formed, so that a manufacturing process can be simplified while guaranteeing the structural strength. In detail, an etching process may be, for example, laser cutting, wet etching, or the like. This is not limited in detail herein.

(33) S102: Forming a plurality of first traces 201 on a first surface 101 of the substrate 10, and forming a plurality of second traces 202 on a second surface 102 of the substrate 10, wherein each of the first traces 201 and each of the second traces 202 respectively extend to one of the first protruding portions 11.

(34) The first trace 201 or the second trace 202 can extend to an edge of the first protruding portion 11 or any position inside the edge of the first protruding portion 11 when extending to the first protruding portion 11, which is not limited in detail herein in the present embodiment.

(35) S103: Printing conductive paste on the first protruding portion 11 to form a conducting layer 30, so that the first trace 201 is connected to the second trace 202.

(36) The conductive paste may be metal paste for achieving electric conduction, such as silver paste, solder paste, and the like.

(37) According to the display panel provided in the present disclosure, the plurality of first protruding portions 11 spaced apart from each other are etched on the first edge 110 of the substrate 10, so that the first trace 201 located on the first surface 101 of the substrate 10 and the second trace 202 located on the second surface 102 of the substrate 10 respectively extend to the first protruding portion 11. The conducting layer 30 covers the first protruding portion 11 to connect the first trace 201 to the second trace 202. Through the arrangement of the first protruding portion 11, each of the first traces 201 can be separated from each of the second traces 202, thereby avoiding a short circuit between adjacent first traces 201 or a short circuit between adjacent second traces 202 while realizing high-precision line width and line spacing of the traces. Therefore, the yield of the wire printing process can be effectively increased, and a simple process is achieved.

(38) The step of manufacturing the first protruding portion 11 on the first edge of the substrate 10 is provided above. Correspondingly, the second protruding portion 12 may also be manufactured on the second edge of the substrate 10. During the manufacturing of the second protruding portion 12, the embodiments of the present disclosure may further include steps S111-S113 below.

(39) S111: Etching the second edge 120 of the substrate 10 to form a plurality of second protruding portions 12.

(41) S113: Printing conductive paste on the second protruding portion 12 to form a conducting layer 30, so that the first trace 201 is connected to the second trace 202.

(42) The first edge 110 is disposed opposite to the second edge 120. The protruding portion is disposed on the edges on the two sides of the substrate 10 for trace printing, so as to increase the density of the printed traces, thereby improving the display performance.

(43) In some embodiments, as shown in FIG. 5, step S103 of printing the conductive paste on the first protruding portion 11 to form the conducting layer 30 further includes steps S301-S303 below.

(46) S303: Printing the conductive paste on the second surface 102 of the substrate 10. The second surface 102 may be a back side of the substrate 10. The conductive paste is printed on three surfaces adjacent to the first protruding portion 11. The conducting layer 30 is formed on each of the three surfaces adjacent to the first protruding portion 11, so that the conducting layer 30 is in a C-shaped structure, so as to ensure that the first trace 201 is connected to the second trace 202. In addition, the first trace 201 is not connected to a trace adjacent to the first trace, or the second trace 202 is not connected to a trace adjacent to the second trace, thereby preventing the short circuit of the traces.

(47) During the printing of the conducting layer 30, the first surface 101 and the second surface 102 may be printed according to a sequential order, and then the third surface 103 is printed. Alternatively, the first surface 101 and the third surface 103 are printed simultaneously, and then the second surface 102 is printed. In this way, the three surfaces of each of the first protruding portions 11 are printed using two printing processes, thereby facilitating the simplification of the printing process.

(48) It may be understood that, when the conducting layer 30 is printed on the second protruding portion 12, a same process may further be adopted, and details will not be described herein again in the present embodiment.

(49) In some embodiments, after step S103 of printing the conductive paste on the first protruding portion 11 to form the conducting layer 30, so that the first trace 201 is connected to the second trace 202, the method may further include step S304 below.
