[0083] In these optional embodiments, the first conductive wire 401 is connected between two adjacent first electrodes 310, which, on the one hand, can reduce the extension distance of the first conductive wire 401, and, on the other hand, can simplify the distribution pattern of the first electrodes 310 and the first conductive wire 401.
[0084] Optionally, the plurality of connection lines 420 include a first connection line 420a and a second connection line 420b, where the first connection line 420a connects one of two adjacent first electrodes 310 to the via hole portion 410, and the second connection line 420b connects the other of the two adjacent first electrodes 310 to the via hole portion 410, thereby allowing the via hole portion 410 to be connected to the first electrodes 310 located on both sides of it in the first direction Y via the first connection line 420a and the second connection line 420b.
[0085] Alternatively, when the first conducting wire 401 is connected between two adjacent first electrodes 310 along the first direction Y, the distance from the via hole portion 410 to the first electrodes 310 located on both sides of the first direction Y is equal, i.e., the extension lengths of the first connecting line and the second connecting line are equal, and the via hole portion 410 is positioned centrally relative to the two adjacent first electrodes 310 along the first direction Y.
[0086] Alternatively, the two first electrodes 310 may be distributed at intervals on both sides of the first conductive line 401, and the first electrodes 310 and the first conductive line 401 are sequentially distributed along the first direction Y. For example, the orthogonal projection of the first electrode 310 on the substrate 100 is rectangular, and the two first electrodes 310 are separately provided on both sides of the first conductive line 401.
[0087] Optionally, the shape of the light-emitting functional structure 320 when orthogonally projected on the substrate 100 matches the shape of the first electrode 310 when orthogonally projected on the substrate 100. For example, if the orthogonal projection of the first electrode 310 on the substrate 100 is rectangular, the shape of the light-emitting functional structure 320 when orthogonally projected on the substrate 100 is also rectangular, and the edges of the light-emitting functional structure 320 when orthogonally projected on the substrate 100 and the edges of the first electrode 310 when orthogonally projected on the substrate 100 are equally spaced.
[0088] 3 and 4 , at least one first electrode 310 connected to a first conductive wire 401 includes a body 311 and a protrusion 312, the protrusion 312 protruding from the body 311 toward the first conductive wire 401, and the protrusion 312 and the first conductive wire 401 are arranged in parallel along the second direction X. This increases the distribution area of the first electrode 310 and further increases the aperture ratio of the display panel 10.
[0089] Alternatively, as shown in Fig. 4, the first conductive wire 401 is connected to the center of the first electrode 310 in the second direction X, and the first electrodes 310 on both sides of the first conductive wire 401 each include a protrusion 312, and the protrusions 312 of the two first electrodes 310 are separately provided on both sides of the first conductive wire 401 in the second direction X, or as shown in Fig. 3, the first conductive wire 401 is connected to one side of the first electrode 310 in the second direction X. By configuring in this way, the light emitting structure 300 divided into two regions can form a large light emitting region.
[0090] As mentioned above, the driving unit 210 includes a thin film transistor 211. In some alternative embodiments, the orthogonal projection of the connecting line 420 on the substrate 100 and the orthogonal projection of the thin film transistor 211 on the substrate 100 are at least partially offset from each other.
[0091] When it is necessary to cut the connecting line 420 using laser light, the effect on the characteristics of the thin film transistor 211 can be improved because the orthogonal projection of the connecting line 420 on the substrate 100 and the orthogonal projection of the thin film transistor 211 on the substrate 100 are at least partially misaligned.
[0092] Optionally, the thin film transistor 211 includes a semiconductor portion 211a, a gate electrode 211b, and an interlayer insulating portion 211c located between the semiconductor portion 211a and the gate electrode 211b, and the orthogonal projection of the connecting line 420 on the substrate 100 is located outside the orthogonal projection of the semiconductor portion 211a, the gate electrode 211b, and the interlayer insulating portion 211c on the substrate 100, thereby further reducing the influence of laser light on the characteristics of the thin film transistor 211.
[0093] Optionally, the driving element layer 200 includes the signal line 220, and the orthogonal projection of the connection line 420 on the substrate 100 is located outside the orthogonal projection of the signal line 220 on the substrate 100, thereby improving the effect of laser light on the signal line 220.
[0094] As mentioned above, the display panel 10 further includes a second electrode layer 600, which is located on one side of the light-emitting functional structure 320 away from the substrate 100, and which includes a through-hole 610, and the orthogonal projection of the connecting line 420 on the substrate 100 is located within the orthogonal projection of the through-hole 610 on the substrate 100.
[0095] In these alternative embodiments, through holes 610 are drilled in the second electrode layer 600 to facilitate laser light passing through the second electrode layer 600 and severing the connecting lines 420 .
[0096] In some optional embodiments, the display panel further includes a plurality of first light-emitting structures, a plurality of second light-emitting structures, and a plurality of third light-emitting structures emitting light of different colors, and at least one of the plurality of first light-emitting structures, the plurality of second light-emitting structures, and the plurality of third light-emitting structures includes the light-emitting structure 300. Optionally, the first light-emitting structure may be a red light-emitting structure, the second light-emitting structure may be a green light-emitting structure, and the third light-emitting structure may be a blue light-emitting structure. In the embodiments of the present application, the third light-emitting structure is described as the light-emitting structure 300.
[0097] In some optional embodiments, the display panel includes sub-pixels 11, which may be formed by combining the above-mentioned first electrodes 310, light-emitting functional structures 320, and a portion of the second electrode layer 600. Optionally, the sub-pixels 11 include a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113 that are spaced apart from each other and have different colors, and the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are adjacently disposed, thereby reducing the distance between different sub-pixels 11.
[0098] Optionally, at least one of the first subpixel 111, the second subpixel 112, and the third subpixel 113 includes the light emitting structure 300. For example, the first subpixel 111 may include a first light emitting structure, the second subpixel may include a second light emitting structure, and the third subpixel may include a third light emitting structure.
[0099] Alternatively, the second sub-pixel 112 is located on one side of the first sub-pixel 111 in the first direction Y, and the third sub-pixel 113 is located on one side of the first sub-pixel 111 in the second direction X, and the first direction Y and the second direction X intersect, thereby reducing the spacing between different sub-pixels.
[0100] Optionally, in the first direction Y, the lengths of the first sub-pixel 111 and the second sub-pixel 112 are the same, and the heights of the two sides are the same to form a rectangular structure, so that the arrangement of the sub-pixels 11 is more regular.
[0101] Optionally, in the first direction Y and / or the second direction X, the lengths of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 are consistent, so that the arrangement of the sub-pixels 11 is more regular.
[0102] Optionally, in the second direction X, one side of the first sub-pixel 111 and one side of the third sub-pixel 113 are at the same height, so that the arrangement of the sub-pixels 111 is more regular.
[0103] Optionally, in the second direction X, one side of the second sub-pixel 112 and one side of the third sub-pixel 113 are at the same height, so that the arrangement of the sub-pixels 11 is more regular.
[0104] Optionally, the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 are elongated and arranged spaced apart in sequence in the first direction Y or the second direction X, thereby making the arrangement of the sub-pixels 11 more regular.
[0105] Optionally, in a second direction X intersecting the first direction Y, the lengths of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 are the same and the heights of the two sides are the same to form a rectangular structure, so that the arrangement of the sub-pixels 11 is more regular.
[0106] In some alternative embodiments, the light emitting structure 300 defines a first region and a second region independent of each other, and two or more first electrodes 310 and light emitting functional structures 320 are located in the first region and the second region, respectively. As shown in FIGS. 1 to 4 , the display panel 10 further includes an isolation structure 700, which is disposed on one side of the driving element layer 200 away from the substrate 100, and which surrounds and forms a plurality of first openings 710, and the light emitting functional structures 320 are separated by the isolation structure 700 and respectively located in each of the first openings 710.
[0107] In these optional embodiments, by installing the separation structure 700, the light emitting structure 300 can be divided into multiple light emitting functional structures 320 installed independently of each other, thereby improving the mutual influence between two adjacent light emitting functional structures 320.
[0108] Optionally, the material of the first sub-layer 730 includes a conductive material, and the display panel 10 further includes a second electrode layer 600, which includes a second electrode located on one side of each light-emitting functional structure 320 away from the substrate 100, and the second electrode is electrically connected to the first sub-layer 730, so that multiple second electrodes can be connected to each other to form surface electrodes via the first sub-layer 730.
[0109] Optionally, the material of the second sublayer 740 comprises a conductive material. Optionally, the material of the third sublayer comprises a conductive material. Optionally, the materials of the second sublayer 740 and the third sublayer are the same.
[0110] Optionally, the first and second regions are light-emitting regions, and the light-emitting functional structure 320 is located in the light-emitting regions to realize the light-emitting display of the display panel.
[0111] Optionally, in other embodiments, the second opening 720 may not be provided in the separation structure 700. When both the first region and the second region are light-emitting regions, if there is a sealing defect or the light-emitting structure contains water vapor, the first region will not emit light, but the second region can still emit light under this condition, which will not affect the overall light emission and does not require cutting the first conductive wire 401.
[0112] For example, the isolation structure 700 may include a first sub-layer 730 and a second sub-layer 740 located on one side of the first sub-layer 730 away from the substrate 100, where the orthogonal projection of the first sub-layer 730 on the substrate 100 is located within the orthogonal projection of the second sub-layer 740 on the substrate 100, i.e., the size of the orthogonal projection of the first sub-layer 730 on the substrate 100 is smaller than the size of the orthogonal projection of the second sub-layer 740 on the substrate 100, thereby forming a recess below the second sub-layer 740. During the fabrication of the light-emitting functional structures 320, the light-emitting material can be partitioned into independent light-emitting functional structures 320 by the isolation structure 700, eliminating the need for a precision mask deposition process.
[0113] Optionally, the isolation structure 700 further includes a third sub-layer, which is located on one side of the first sub-layer 730 facing the substrate 100, and the orthogonal projection of the first sub-layer 730 on the substrate 100 is located within the orthogonal projection of the third sub-layer on the substrate 100. When side etching is performed on the first sub-layer 730 to reduce its size during fabrication of the isolation structure 700, the third sub-layer can provide protection to the underlying layer structure and improve the impact of the side etching on other film layers.
[0114] In some optional embodiments, a second opening 720 is further provided in the isolation structure 700 located between the first region and the second region, such that the orthogonal projection of the first conductive line 401 on the substrate 100 at least partially overlaps with the orthogonal projection of the second opening 720 on the substrate 100. This allows the laser light to pass through the second opening 720 to reach the first conductive line 401 and cut the first conductive line 401 into two parts that are insulated from each other, and the size of the second opening 720 is smaller than that of the first opening 710.
[0115] Optionally, the orthogonal projection of the through hole 610 of the second electrode layer 600 on the substrate 100 and the orthogonal projection of the second opening 720 on the substrate 100 at least partially overlap, thereby allowing laser light to pass through the through hole 610 and the second opening 720 simultaneously.
[0116] Optionally, as referred to above, the driving element layer includes a driving unit, the first conductive wire 401 includes a via hole portion 410 and a connecting line 420 connecting the via hole portion 410 and the first electrode 310, the via hole portion 410 and the driving unit 210 are connected through a via hole, and the orthogonal projection of the connecting line 420 on the substrate 100 and the orthogonal projection of the second opening 720 on the substrate 100 at least partially overlap, whereby the laser light can pass through the second opening 720 to reach the connecting line 420 and cut the connecting line 420 into two parts independent of each other within the connecting line 420.
[0117] Optionally, the display panel 10 further includes a pixel definition layer 800, which is located between the isolation structure 700 and the driving element layer 200, and which includes a pixel limiting portion 810 and a pixel opening 820 opened in the pixel limiting portion 810, the pixel opening 820 communicating with the first opening 710, and the pixel limiting portion 810 covering the first conductive line 401.
[0118] In these optional embodiments, the light-emitting functional structure 320 may be disposed in the pixel opening 820, and the pixel limiting portion 810 may cover the first conductive line 401. When the isolation structure 700 is subsequently fabricated, the pixel limiting portion 810 may provide protection for the first conductive line 401, thereby alleviating the problem that the first conductive line 401 is easily affected and broken.
[0119] Optionally, the material of the pixel defining layer 800 comprises a light-transmitting material, so that the laser light can pass through the pixel defining layer 800 and cut the first conductive wire 401 .
[0120] Alternatively, the isolation structure 700 may be located on one side of the pixel limiting portion 810 away from the substrate 100 .
[0121] In some optional embodiments, the first electrode 310, the light-emitting functional structure 320, and a portion of the second electrode layer 600 located on the light-emitting functional structure 320 constitute a sub-pixel 11. In this case, at least one sub-pixel 11 includes two or more pixel blocks 12, two adjacent pixel blocks 12 are spaced apart by an isolation structure 700, each pixel block 12 includes a first electrode 310 and a light-emitting functional structure 320 located on one side of the first electrode 310 away from the substrate 100, and the at least two first electrodes 310 are connected to each other via a first conductive line 401.
[0122] In these alternative embodiments, the same sub-pixel 11 includes two or more pixel blocks 12, and the first electrodes 310 of the two or more pixel blocks 12 are connected to each other via the first conductive wire 401. When a display abnormality occurs in one of the pixel blocks 12 of the sub-pixel 11, the first conductive wire 401 can be cut off, thereby cutting off the abnormal pixel block 12 and allowing the other pixel blocks 12 to display normally, thereby improving the display effect of the display panel 10.
[0123] In some alternative embodiments, the plurality of subpixels 11 are a first subpixel 111, a second subpixel 112, and a third subpixel 113, respectively, the first subpixel 111 and the second subpixel 112 being arranged in parallel along a first direction Y, the third subpixel 113 and the first subpixel 111 and the second subpixel 112 being arranged in parallel along a second direction X, and at least one of the first subpixel 111, the second subpixel 112, and the third subpixel 113 includes two pixel blocks 12.
[0124] For example, the first subpixel 111 may be a red subpixel, the second subpixel 112 may be a green subpixel, and the third subpixel 113 may be a blue subpixel. At least one of the red, green, and blue subpixels may include two of the above pixel blocks 12.
[0125] Alternatively, the distribution area of a single third sub-pixel 113 may be larger than the distribution areas of the first sub-pixel 111 and the second sub-pixel 112, and the third sub-pixel 113 may include two or more pixel blocks 12 arranged in parallel along the first direction Y. For example, the third sub-pixel 113 may include two pixel blocks 12, where one pixel block 12 and the first sub-pixel 111 are arranged in parallel along the second direction X, and the other pixel block 12 and the second sub-pixel 112 are arranged in parallel along the second direction X. This makes the arrangement of the multiple sub-pixels 11 simpler and more regular.
[0126] 5, a single first sub-pixel 111 may include two adjacent pixel blocks 12, and / or a single second sub-pixel 112 may include two adjacent pixel blocks 12, and the third sub-pixel 113 may be integrally formed. Optionally, the two pixel blocks 12 of the first sub-pixel 111 may be arranged in parallel along the first direction Y or the second direction X. Optionally, the two pixel blocks 12 of the second sub-pixel 112 may be arranged in parallel along the first direction Y or the second direction X.
[0127] Furthermore, in some alternative embodiments, as shown in FIG. 6, a single first sub-pixel 111, a single second sub-pixel 112 and a single third sub-pixel 113 each comprise two adjacent pixel blocks 12.
[0128] As shown in FIGS. 1 to 6, an embodiment of the first aspect of the present application further provides a display panel 10, which includes a substrate 100, a driving element layer 200 disposed on the substrate 100, and a driving element layer 200 disposed on one side of the driving element layer 200 away from the substrate 100, defining a first region and a second region independent of each other, two or more first electrodes 310, and light-emitting functional structures 320 respectively located on one side of the first electrodes 310 away from the substrate 100 and spaced apart from each other, The light-emitting structure 300 includes electrodes 310 and light-emitting functional structures 320 located in a first region and a second region, respectively, two or more first electrodes 310 spaced apart and connected to each other via first conductive wires 401, with the first conductive wires 401 located between two adjacent first electrodes 310; and an isolation structure 700 located on one side of the driving element layer 200 away from the substrate 100, surrounding and forming a plurality of first openings 710, separating the light-emitting functional structures 320 and positioning them in each first opening 710.
[0129] In these optional embodiments, two or more first electrodes 310 of the same light-emitting structure 300 are spaced apart and connected to each other via the first conductive wire 401, so that the two or more first electrodes 310 of the same light-emitting structure 300 can be connected to the same driving unit 210 of the driving element layer 200 via the first conductive wire 401, facilitating division of the light-emitting structure 300 into two parts without increasing the complexity of the driving element layer 200. The separation structure 700 can separate the two light-emitting functional structures 320 of the light-emitting structure 300, thereby improving the mutual influence between two adjacent light-emitting functional structures 320. If a display defect occurs in one of the two or more light-emitting functional structures 320 of the light-emitting structure 300, the remaining light-emitting functional structures 320 can continue to emit light, thereby improving the display effect and performance of the display panel 10.
[0130] Optionally, the installation methods of the isolation structure 700, the driving element layer 200, and the first conductive wire 401 may be the same as those described above, and will not be described again here. Optionally, the display panel 10 may further include a pixel definition layer 800, and the shape of the pixel definition layer 800 may be the same as those described above, and will not be described again here.
[0131] As shown in Figures 1 to 8, an embodiment of the first aspect of the present application further provides a display panel 10, comprising: a substrate 100; a plurality of sub-pixels 11 disposed on the substrate 100; and an isolation structure 700, wherein at least one of the sub-pixels 11 comprises two or more pixel blocks 12, and two adjacent pixel blocks 12 are spaced apart by the isolation structure 700, and each of the pixel blocks 12 comprises a first electrode 310 and a light-emitting functional structure 320 located on one side of the first electrode 310 away from the substrate 100, and at least two of the first electrodes 310 are connected to each other via a first conductive wire 401.
[0132] In this embodiment, the same sub-pixel 11 includes two or more pixel blocks 12, and the first electrodes 310 of the two or more pixel blocks 12 are connected to each other via the first conductive wire 401. When one of the pixel blocks 12 of the sub-pixel 11 has a display abnormality, the first conductive wire 401 can be cut off, thereby cutting off the abnormal pixel block 12 and allowing the other pixel blocks 12 to display normally, thereby improving the display effect of the display panel 10.
[0133] Optionally, the display panel 10 may further include a driving element layer 200 and a pixel definition layer 800, and the installation methods of the sub-pixels 11, the isolation structure 700, the driving element layer 200 and the pixel definition layer 800 are the same as those described above, and will not be described again here.
[0134] As shown in Figures 7 and 8, an embodiment of the first aspect of the present application further provides a display panel 10, including: a substrate 100; a driving element layer 200 disposed on the substrate 100 and including a driving unit 210; and a light-emitting structure 300 disposed on one side of the driving element layer 200 away from the substrate 100, defining a first region and a second region independent of each other, the light-emitting structure 300 including first electrodes 310 located in the first region and the second region, and light-emitting functional structures 320 located on one side of the first electrodes away from the substrate 100 and spaced apart, the first electrodes 310 located in the first region being electrically connected to the driving unit 210 via second conductive wires 402, and the first electrodes 310 located in the second region being independently disposed and not connected to the driving unit 210.
[0135] In these optional embodiments, the first electrodes 310 in the second region are installed independently and are not connected to the driving unit 210, so that the first electrodes 310 in the first region do not affect the normal operation of the first electrodes 310 in the second region, thereby improving the display effect of the display panel.
[0136] In some optional embodiments, the display panel includes a third conducting wire 403, and the third conducting wire 403 is provided with an insulating gap 431 that divides the third conducting wire 403 into two parts that are spaced apart and insulated from each other, so that the first electrode 310 connected by the third conducting wire 403 is not connected to the driving unit 210.
[0137] Optionally, the second conducting wire 402 includes the above-mentioned via hole portion 410 and connecting wire 420, the via hole portion 410 and the driving unit 210 are connected through the via hole, and the connecting wire 420 connects the via hole portion 410 and the first electrode 310. Optionally, the third conducting wire 403 and the via hole portion 410 are disconnected.
[0138] Optionally, as described above, the display panel further includes an isolation structure 700, which surrounds and forms a plurality of first openings 710 and second openings 710, the light-emitting functional structures 320 are separated by the isolation structure 700 and are respectively located in each first opening 710, and the orthogonal projection of the insulating gap 431 on the substrate 100 is located within the orthogonal projection of the second opening 720 on the substrate 100, so that the laser light can pass through the second opening 720 of the isolation structure 700 to cut the third conductive wire 403.
[0139] Optionally, as described above, when the display panel includes a thin film transistor 211, the orthogonal projection of the insulating gap 431 on the substrate 100 and the orthogonal projection of the thin film transistor 211 on the substrate 100 are at least partially offset to improve the impact on the thin film transistor 211 when the laser light cuts the third conductive wire 403.
[0140] Optionally, the orthogonal projection of the insulating gap on the substrate 100 is positioned outside the orthogonal projection of the semiconductor portion 211a, the gate electrode 211b, and the interlayer insulating portion 211c on the substrate 100. This improves the effect on the thin film transistor 211 when the laser light cuts the third conductive line 403.
[0141] Optionally, the orthogonal projection of the insulating gap 431 on the substrate 100 is positioned outside the orthogonal projection of the signal line on the substrate 100 to improve the effect on the signal line when the laser light cuts the third conductive line 403 .
[0142] Optionally, the difference between the embodiment of the present application and any of the above-mentioned display panels 10 is that the installation methods of the second conductive wire 402 and the third conductive wire 403 and the above-mentioned first conductive wire 401 are different. Other installation methods can be referred to above and will not be described again here.
[0143] In at least one embodiment of the present disclosure, the isolation structure 700 extends along the first direction and the second direction, and the sub-pixels 11 form pixel blocks 12 adjacent in the first direction and / or pixel blocks 12 adjacent in the second direction with a gap therebetween by the isolation structure 700. By providing the isolation structure 700 and forming first openings 710 corresponding to each pixel block 12, when fabricating the pixel blocks 12, the light-emitting functional structures 320 of each pixel block 12 are separated by the isolation structure 700 and can be deposited in each first opening 710, thereby forming pixel blocks 12 separated from each other in the first direction and the second direction. By configuring the isolation structure 700 in this manner, the pixel blocks 12 are effectively separated from one another, reducing the mutual influence of the pixel blocks 12. When a dark dot problem occurs in one pixel block 12, the other pixel blocks 12 can maintain normal emission, thereby ensuring normal emission of the display panel. That is, by dividing the sub-pixel 11 into multiple pixel blocks 12 by the isolation structure 700, the impact of a single dark dot defect on the display effect of the display panel can be reduced.
[0144] An embodiment of the second aspect of the present application further provides a display device, which includes the display panel 10 according to any of the embodiments of the first aspect. Because the display device according to the embodiment of the second aspect of the present application includes the display panel 10 according to any of the embodiments of the first aspect, the display device according to the embodiment of the second aspect of the present application has the beneficial effects of the display panel 10 according to any of the embodiments of the first aspect, which will not be described again here.
[0145] The display devices of the embodiments of the present application include, but are not limited to, devices with display functions such as mobile phones, personal digital assistants (abbreviated as PDA), tablet computers, e-books, televisions, entrance guards, smart landlines, consoles, etc.
[0146] A third aspect of the present application further provides a method for repairing a display panel 10, which may be the display panel 10 according to any of the embodiments of the first aspect described above, and as shown in Figures 1 to 9, the method for repairing the display panel 10 includes the following steps S01 to S04.
[0147] Step S01 involves fabricating a first electrode layer 13 on one side of the substrate, the first electrode layer 13 including a first conductive wire 401 and a plurality of spaced apart first electrodes 310, the two or more first electrodes 310 being connected to each other via the first conductive wire 401.
[0148] Optionally, the substrate may include a substrate 100 and a driving element layer 200 disposed on the substrate 100. The driving element layer 200 may include a driving unit 210. Optionally, the substrate may further include a first insulating layer 500 located on one side of the driving element layer 200 away from the substrate 100, and the first insulating layer 500 includes a first via hole 510. When fabricating the first electrode layer 13 in step S01, at least a portion of a conductive material may be disposed in the first via hole 510, thereby electrically connecting the first conductive wire 401 and the driving unit 210 to each other.
[0149] In step S02, a light-emitting functional structure 320 is fabricated on one side of the first electrode layer 13 away from the substrate, and the light-emitting functional structure 320 located on two or more first electrodes 310 connected by first conductive wires 401 is combined with the corresponding first electrodes 310 to form an identical light-emitting structure 300.
[0150] Optionally, after step S02, film layer structures such as the second electrode layer 600 and the package layer 900 can be further fabricated on the light-emitting function structure 320.
[0151] In step S03, the light-emitting structure 320 is turned on, and the lighting information of the light-emitting structure 320 is obtained.
[0152] In step S04, it is confirmed whether or not to cut off first conducting wire 401 based on the lighting information.
[0153] In the method according to the embodiment of the present application, first, when fabricating the first electrode layer 13, a first conductive wire 401 connects two or more first electrodes 310, and the two or more first electrodes 310 connected by the first conductive wire 401 and the light-emitting structures 320 located thereon constitute the same light-emitting structure 300. In step S03, brightness information of the two or more light-emitting structures 320 of the same light-emitting structure 300 can be obtained. Based on the brightness information, the first conductive wire 401 can be cut, thereby ameliorating the influence of a brightness abnormality of one light-emitting structure 320 on the other light-emitting structures 320. Therefore, the method for repairing a display panel 10 according to the embodiment of the third aspect of the present application can repair a display abnormality in the display panel 10.
[0154] The inventors found that during the fabrication of the display panel 10, metal particles may be generated, and the metal particles may fall between the first electrode 310 and the second electrode layer 600, resulting in a short circuit connection between the first electrode 310 and the second electrode layer 600, and further causing brightness problems in the light-emitting structure 300.
[0155] In the embodiment of the present application, if a brightness problem occurs in the light emitting structure 300, by installing the first conductive wire 401, during the manufacturing process of the display panel, the first conductive wire 401 can be cut to cut the first electrode 310 and the via hole part 410 corresponding to the light emitting functional structure 320 where the brightness problem occurs in the light emitting structure 300, and further improve the short connection between the first electrode 310 and the second electrode layer 600, so that the other light emitting functional structures 320 can continue to emit light normally and the display problem of the display panel 10 can be improved.
[0156] As described above, the substrate includes the driving element layer 200, the driving element layer 200 includes the driving unit 210, the first conductive wire 401 includes the via hole part 410, and the first conductive wire 401 is electrically connected to the driving unit 210 through the via hole part 410. In this case, in step S04, if there is a light-emitting structure 320 with abnormal brightness, the first conductive wire 401 is cut between the first electrode 310 corresponding to the light-emitting structure 320 with abnormal brightness and the via hole part 410, thereby improving the effect of the light-emitting structure 320 with abnormal brightness on the display of other light-emitting structures 320.
[0157] Optionally, as described above, if the first conductive wire 401 includes the connecting wire 420, in step S04, the connecting wire can be cut at the connecting wire 420 to form an insulating gap 431. After cutting, the first conductive wire 401 becomes the second conductive wire 402 and the third conductive wire 403, the second conductive wire 402 connects the via hole portion 410 and the first electrode 310, and the third conductive wire 403 has the insulating gap 431.
[0158] Alternatively, if there is no abnormal light-emitting structure 320, the first conductive wire 401 is not cut.
[0159] Optionally, in step S04, if there is a brightness difference between the light-emitting functional structures 320 corresponding to two or more first electrodes 310 connected by the first conductive wire 401, the light-emitting functional structure 320 with the smallest brightness is identified as the light-emitting functional structure 320 with abnormal brightness.
[0160] As described above, if the presence of metal particles between the first electrode 310 and the second electrode layer 600 causes a short circuit between the first electrode 310 and the second electrode layer 600, the light-emitting structure 320 between the short-circuited first electrode 310 and the second electrode layer 600 will not light up. However, because the first conductive wire 401 is small in size and has high resistance, the light-emitting structures 320 between the other first electrodes 310 and the second electrode layer 600 connected by the first conductive wire 401 will be affected and their brightness will decrease. In this embodiment, the light-emitting structure 320 with the lowest brightness is identified as the abnormally bright light-emitting structure 320, and the first conductive wire 401 is cut between the first electrode 310 corresponding to the abnormally bright light-emitting structure 320 and the via hole 410. This disconnects the first electrode 310 corresponding to the abnormally bright light-emitting structure 320 from the other first electrodes 310, thereby alleviating the influence of the abnormally bright light-emitting structure 320 on the other light-emitting structures 320.
[0161] In another alternative embodiment, before step S04, the method further includes a step of obtaining pattern information when the display panel 10 is not lit, and determining the position information of impurities based on the pattern information. In step S04, the light-emitting functional structures 320 in the region that is not lit and has impurities are determined to be light-emitting functional structures 320 with abnormal brightness based on the position information and the light-emitting information.
[0162] In the embodiment of the present application, the location information of the impurities, i.e., the location information of the metal particles, can be directly obtained, and when detecting the abnormal light-emitting structure 300, it is possible to further identify the region of the abnormal light-emitting structure 300 in which the impurities are present, and further to determine that the light-emitting structure 320 in the region that is not lit and has impurities is the light-emitting structure 320 with abnormal brightness, thereby easily and accurately detecting the abnormal light-emitting structure 320.
[0163] Although the present application has been described with reference to preferred embodiments, various modifications may be made and equivalents may be substituted for the components thereof without departing from the scope of the present application. In particular, the technical features described in each embodiment may be combined in any manner as long as there is no structural contradiction. The present application is not limited to the specific embodiments disclosed in this specification, but includes all technical solutions falling within the scope of the claims.
