The first connection line 420a connects one of two adjacent first electrodes 310 and the via hole portion 410, and the second connection line 420b connects the other of the two adjacent first electrodes 310 and the via hole portion 410. Thereby, the via hole portion 410 can be connected to the first electrodes 310 located on both sides of its own first direction Y via the first connection line 420a and the second connection line 420b.

[0085] Optionally, when the first conductor 401 is connected between two adjacent first electrodes 310 along the first direction Y, the distances from the via hole portion 410 to the first electrodes 310 located on both sides of its first direction Y are equal, that is, the extension lengths of the first connection line and the second connection line are equal, and the via hole portion 410 is disposed in the center with respect to the two adjacent first electrodes 310 along the first direction Y.

[0086] Optionally, the two first electrodes 310 may be distributed at intervals on both sides of the first conductor 401, and the first electrodes 310 and the first conductor 401 are sequentially distributed along the first direction Y.

[0093] Optionally, the drive element layer 200 includes a signal line 220. The orthographic projection of the connection line 420 on the substrate 100 is located outside the orthographic projection of the signal line 220 on the substrate 100, thereby improving the influence of the laser light on the signal line 220.

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, forming a rectangular structure, thereby making the arrangement of the sub-pixels 11 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 the same, whereby the arrangement of the sub-pixels 11 is more regular.

As shown in FIGS. 1 to 4, the display panel 10 further includes a separation structure 700. The separation structure 700 is installed on one side away from the substrate 100 of the driving element layer 200. The separation structure 700 is formed by surrounding a plurality of first openings 710, and the light-emitting functional structures 320 are separated by the separation structure 700 and are respectively located in each first opening 710.

[0107] In these alternative embodiments, by providing the separation structure 700, the light-emitting structure 300 can be partitioned into a plurality of light-emitting functional structures 320 that are separately installed from 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, the display panel 10 further includes a second electrode layer 600, the second electrode layer 600 includes a second electrode located on one side away from the substrate 100 of each light-emitting functional structure 320, the second electrode is electrically connected to the first sub-layer 730, whereby a plurality of second electrodes can be connected to each other through the first sub-layer 730 to form a surface electrode.

When both the first region and the second region are light-emitting regions, if there is a sealing defect or the light-emitting functional structure contains water vapor, the first region does not emit light, but even in this state, the second region can emit light without affecting the overall light emission, and it is not necessary to cut the first conductor 401.

[0112] The installation method of the separation structure 700 is various. For example, the separation structure 700 includes a first sub-layer 730 and a second sub-layer 740 located on one side away from the substrate 100 of the first sub-layer 730. The orthographic projection of the substrate 100 of the first sub-layer 730 is located within the orthographic projection of the substrate 100 of the second sub-layer 740. That is, the size of the orthographic projection of the substrate 100 of the first sub-layer 730 is smaller than the size of the orthographic projection of the substrate 100 of the second sub-layer 740, thereby forming a concave portion under the second sub-layer 740. During the fabrication of the light-emitting functional structure 320, the light-emitting materials can be partitioned into the light-emitting functional structures 320 that are independent of each other by the separation structure 700, and the precise mask evaporation process can be omitted.

During the fabrication of the separation structure 700, when side etching is performed on the first sub-layer 730 to reduce its size, the third sub-layer provides protection to the bottom layer structure and can improve the influence on other film layers by side etching.

[0114] In some alternative embodiments, a second opening 720 is further provided in the separation structure 700 located between the first region and the second region. The orthographic projection of the first conductor 401 on the substrate 100 and the orthographic projection of the second opening 720 on the substrate 100 overlap at least partially. Thereby, the laser light can pass through the second opening 720 and reach the first conductor 401, and the first conductor 401 can be cut into two insulated parts from each other. The size of the second opening 720 is smaller than that of the first opening 710.

[0115] Optionally, the orthographic projection of the through-hole 610 of the second electrode layer 600 on the substrate 100 and the orthographic projection of the second opening 720 on the substrate 100 overlap at least partially, whereby the laser light can pass through the through-hole 610 and the second opening 720 simultaneously.

[0116] Optionally, such that the above content is referred to, the driving element layer includes a driving unit, the first conductor 401 includes a via hole portion 410 and a connection 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 via a via hole, and the orthographic projection of the connection line 420 on the substrate 100 and the orthographic projection of the second opening 720 on the substrate 100 at least partially overlap, whereby the laser light passes through the second opening 720 and reaches the connection line 420, and the connection line 420 can be cut into two independent parts within the connection line 420.

[0118] In these alternative embodiments, the light-emitting functional structure 320 may be disposed in the pixel opening 820, the pixel limiting portion 810 covers the first conductor 401, and when the separation structure 700 is then fabricated, the pixel limiting portion 810 provides protection for the first conductor 401, and the problem that the first conductor 401 is easily affected and broken can be improved.

[0119] Optionally, the material of the pixel definition layer 800 includes a light-transmissive material, whereby the laser light can pass through the pixel definition layer 800 and cut the first conductor 401.

[0120] Optionally, the separation structure 700 may be disposed on one side of the pixel limiting portion 810 away from the substrate 100.

[0121] In some alternative embodiments, the first electrode 310, the light-emitting functional structure 320, and a part of the second electrode layer 600 located on the light-emitting functional structure 320 constitute the sub-pixel 11. In that case, at least one sub-pixel 11 includes two or more pixel blocks 12, and two adjacent pixel blocks 12 are spaced apart by a separation structure 700. Each pixel block 12 includes the first electrode 310 and the light-emitting functional structure 320 located on one side away from the substrate 100 of the first electrode 310. At least two first electrodes 310 are connected to each other via the first conductor 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 conductor 401. When a display abnormality occurs in one of the multiple pixel blocks 12 of the sub-pixel 11, the first conductor 401 can be cut, thereby blocking the pixel block 12 with the display abnormality, and the other pixel blocks 12 can be displayed normally. Thereby, the display effect of the display panel 10 is improved.

[0123] In some alternative embodiments, the multiple sub-pixels 11 are the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 respectively. The first sub-pixel 111 and the second sub-pixel 112 are provided in parallel along the first direction Y, and the third sub-pixel 113, the first sub-pixel 111, and the second sub-pixel 112 are provided in parallel along the second direction X. At least one of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 includes two pixel blocks 12.

[0124] For example, the first sub-pixel 111 may be a red sub-pixel, the second sub-pixel 112 may be a green sub-pixel, and the third sub-pixel 113 may be a blue sub-pixel. At least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel may include two of the above pixel blocks 12.

[0125] Optionally, the distribution area of a single third sub-pixel 113 is 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, one of which is arranged in parallel with the first sub-pixel 111 along the second direction X, and the other is arranged in parallel with the second sub-pixel 112 along the second direction X. Thereby, the arrangement of the plurality of sub-pixels 11 is simpler and more regular.

[0126] In another alternative embodiment, as shown in FIG. 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 installed. 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] In still 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 all include two adjacent pixel blocks 12.

Two or more first electrodes 310 and light-emitting functional structures 320 are respectively located in the first region and the second region, two or more first electrodes 310 are spaced apart from each other, and are connected to each other via a first conductor 401. The first conductor 401 is located between two adjacent first electrodes 310. A separation structure 700 is disposed on one side of the driving element layer 200 away from the substrate 100, formed by surrounding a plurality of first openings 710, and separating the light-emitting functional structures 320 and respectively positioning them in each of the first openings 710.

[0129] In these alternative embodiments, two or more first electrodes 310 of the same light-emitting structure 300 are spaced apart from each other and connected to each other via a first conductor 401. Thereby, 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 conductor 401, making it easier to divide the light-emitting structure 300 into two parts without increasing the complexity of the driving element layer 200. The separation structure 700 can partition 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. When a display defect occurs in one of 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 of the display panel 10 and enhancing the display performance of the display panel 10.

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. At least two of the first electrodes 310 are connected to each other via a first conductor 401.

[0132] In the embodiment of the present application, 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 a first conductor 401. When a display abnormality occurs in one of the plurality of pixel blocks 12 of the sub-pixel 11, the first conductor 401 can be cut off, thereby blocking the pixel block 12 with the display abnormality, and the other pixel blocks 12 can be displayed normally. Thereby, the display effect of the display panel 10 is improved.

[0133] Optionally, the display panel 10 may further include a driving element layer 200 and a pixel definition layer 800. The installation methods of the sub-pixel 11, the separation structure 700, the driving element layer 200, and the pixel definition layer 800 are the same as those described above, and will not be repeated here.

The first electrode 310 located in the first region is electrically connected to the driving unit 210 through a second conductor 402, and the first electrode 310 located in the second region is independently disposed and not connected to the driving unit 210, including a light-emitting structure 300.

[0135] In these alternative embodiments, the first electrode 310 in the second region is independently disposed and not connected to the driving unit 210, whereby the first electrode 310 in the first region does not affect the normal operation of the first electrode 310 in the second region, thereby improving the display effect of the display panel.

[0136] In some alternative embodiments, the display panel includes a third conductor 403, an insulating gap 431 is provided in the third conductor 403, and the insulating gap 431 partitions the third conductor 403 into two spaced-apart and insulated portions, whereby the first electrode 310 connected by the third conductor 403 is not connected to the driving unit 210.

[0137] Optionally, the second conductor 402 includes the above-mentioned via hole portion 410 and connection line 420, the via hole portion 410 and the driving unit 210 are connected through a via hole, and the connection line 420 connects the via hole portion 410 and the first electrode 310. Optionally, the third conductor 403 and the via hole portion 410 are blocked.

[0138] Optionally, as described above, the display panel further includes a separation structure 700, the separation structure 700 is formed to surround a plurality of first openings 710 and second openings 710, the light-emitting functional structure 320 is separated by the separation structure 700, and is respectively located in each first opening 710. The orthographic projection of the substrate 100 in the insulating gap 431 is located within the orthographic projection of the substrate 100 in the second opening 720. Thereby, the laser light can pass through the second opening 720 of the separation structure 700 to cut the third conductor 403.

[0139] Optionally, as described above, when the display panel includes the thin-film transistor 211, the orthographic projection of the substrate 100 in the insulating gap 431 and the orthographic projection of the substrate 100 in the thin-film transistor 211 are at least partially offset, improving the influence on the thin-film transistor 211 when the laser light cuts the third conductor 403.

[0140] Optionally, the orthographic projection of the substrate 100 in the insulating gap is located outside the orthographic projections of the semiconductor portion 211a, the gate electrode 211b, and the interlayer insulating portion 211c in the substrate 100. This improves the influence on the thin-film transistor 211 when the laser light cuts the third conductor 403.

[0141] Optionally, the orthographic projection of the substrate 100 in the insulating gap 431 is located outside the orthographic projection of the signal line in the substrate 100, improving the influence on the signal line when the laser light cuts the third conductor 403.

[0142] Optionally, the difference between the embodiment of the present application and any of the above display panels 10 is that the installation methods of the second conductor 402 and the third conductor 403 and the above first conductor 401 are different. For other installation methods, refer to the above, and the description will not be repeated here.

[0143] In at least one embodiment of the present disclosure, the separation structure 700 extends along a first direction and a second direction, and the sub-pixel 11 is spaced apart from the pixel block 12 adjacent in the first direction and / or the pixel block 12 adjacent in the second direction by the separation structure 700. By installing the separation structure 700 and forming the first openings 710 corresponding to each pixel block 12, when manufacturing the pixel block 12, the light-emitting functional structure 320 of each pixel block 12 can be partitioned by the separation structure 700 and deposited in each first opening 710, thereby forming pixel blocks 12 partitioned from each other in the first direction and the second direction. By installing the separation structure 700 in this way, the partitioning effect between the pixel blocks 12 is good, the mutual influence between the pixel blocks 12 is reduced, and when a vanishing point problem occurs in one pixel block 12, the other pixel blocks 12 can maintain normal light emission, thereby ensuring the normal light emission of the display panel. That is, by dividing the sub-pixel 11 into a plurality of pixel blocks 12 by the separation structure 700, the influence on the display effect of the display panel due to the defect of a single vanishing point can be improved.

[0146] The third aspect of the present application further provides a method for repairing the display panel 10, and the display panel 10 may be the display panel 10 according to the embodiment of any of the above first aspects. As shown in FIGS. 1 to 9, the method for repairing the display panel 10 includes the following steps S01 to S04.

[0147] In step S01, a first electrode layer 13 is fabricated on one side of the substrate. The first electrode layer 13 includes a first conductor 401 and a plurality of first electrodes 310 disposed at intervals, and two or more first electrodes 310 are connected to each other via the first conductor 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 part of the conductive material can be disposed in the first via hole 510, whereby the first conductor 401 and the driving unit 210 are electrically connected 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 the first conductor 401 and the corresponding first electrodes 310 are combined to form the same light-emitting structure 300.

[0150] Optionally, after step S02, further film layer structures such as a second electrode layer 600 and a package layer 900 can be continuously fabricated on the light-emitting functional structure 320.

[0151] In step S03, the light-emitting functional structure 320 is turned on, and the lighting information of the light-emitting functional structure 320 is acquired.

[0152] In step S04, it is confirmed whether to cut the first conductor 401 based on the lighting information.

[0153] In the method according to the embodiment of the present application, first, when manufacturing the first electrode layer 13, the first conductor 401 connects two or more first electrodes 310, and two or more first electrodes 310 connected by the first conductor 401 and the light-emitting functional structure 320 located thereon constitute the same light-emitting structure 300. In step S03, the luminance information of two or more light-emitting functional structures 320 of the same light-emitting structure 300 can be obtained. Based on the luminance information, the first conductor 401 can be cut, thereby improving the influence of the light-emitting functional structure 320 with abnormal luminance on other light-emitting functional structures 320. Therefore, the repair method of the display panel 10 according to the embodiment of the third aspect of the present application can repair the display abnormality of the display panel 10.

[0154] The inventor found that during the manufacture 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 a luminance problem in the light-emitting structure 300.

[0155] In the embodiment of the present application, when a luminance problem occurs in the light-emitting structure 300, by installing the first conductor 401, during the manufacture of the display panel, the first conductor 401 can be cut, and the first electrode 310 corresponding to the light-emitting functional structure 320 in which the luminance problem occurs in the light-emitting structure 300 and the via hole portion 410 can be cut. Furthermore, the short-circuit connection between the first electrode 310 and the second electrode layer 600 can be improved, so that other light-emitting functional structures 320 continue to emit light normally, and the display problem of the display panel 10 is 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 conductor 401 includes the via hole portion 410, and the first conductor 401 is electrically connected to the driving unit 210 via the via hole portion 410. In that case, in step S04, when there is a light-emitting functional structure 320 with abnormal luminance, the first conductor 401 is cut between the first electrode 310 corresponding to the light-emitting functional structure 320 with abnormal luminance and the via hole portion 410. Thereby, the influence of the light-emitting functional structure 320 with abnormal luminance on the display of other light-emitting functional structures 320 is improved.

[0157] Optionally, as described above, when the first conductor 401 includes the connection line 420, in step S04, the connection line can be cut by the connection line 420 to form the insulation gap 431. The first conductor 401 after cutting becomes the second conductor 402 and the third conductor 403. The second conductor 402 connects the via hole portion 410 and the first electrode 310, and there is an insulation gap 431 in the third conductor 403.

[0158] Optionally, when there is no light-emitting functional structure 320 with display abnormality, the cutting process is not performed on the first conductor 401.

[0159] Optionally, in step S04, when there is a luminance difference in the light-emitting functional structures 320 corresponding to two or more first electrodes 310 connected by the first conductor 401, it is confirmed that the light-emitting functional structure 320 with the lowest luminance is the light-emitting functional structure 320 with abnormal luminance.

[0160] As described above, since metal particles exist between the first electrode 310 and the second electrode layer 600, when a short - circuit connection occurs between the first electrode 310 and the second electrode layer 600, the light - emitting functional structure 320 between the first electrode 310 and the second electrode layer 600 that causes the short - circuit connection does not light up. However, because the size of the first conductor 401 is small and its resistance is large, the light - emitting functional structure 320 between the other first electrode 310 and the second electrode layer 600 connected by the first conductor 401 is affected and its brightness decreases. In the embodiment of the present application, it is confirmed that the light - emitting functional structure 320 with the lowest brightness is the light - emitting functional structure 320 with abnormal brightness. The first conductor 401 is cut between the first electrode 310 corresponding to the light - emitting functional structure 320 with abnormal brightness and the via - hole portion 410, so that the first electrode 310 corresponding to the light - emitting functional structure 320 with abnormal brightness and other first electrodes 310 are blocked, and the influence of the light - emitting functional structure 320 with abnormal brightness on other light - emitting functional structures 320 is improved.

[0161] In another alternative embodiment, before step S04, it further includes the steps of obtaining pattern information when the display panel 10 is not lit and confirming the position information of impurities based on the pattern information. In step S04, based on the position information and the lighting information, it is confirmed that the light - emitting functional structure 320 in the area that is not lit and has impurities is the light - emitting functional structure 320 with abnormal brightness.

[0162] In the embodiment of the present application, the position information of impurities, that is, the position information of metal particles, can be directly obtained. When finding the light - emitting structure 300 with display anomalies, it is further possible to specify which light - emitting functional structure 320 in the light - emitting structure 300 with display anomalies has impurities in the area. Furthermore, it is confirmed that the light - emitting functional structure 320 in the area that is not lit and has impurities is the light - emitting functional structure 320 with abnormal brightness, and the light - emitting functional structure 320 with abnormal brightness can be easily and accurately found.

[0163] The present application has been described with reference to the preferred embodiments, but various improvements can be made without departing from the scope of the present application, and the components can be replaced with equivalents. In particular, as long as there is no structural contradiction, the technical features described in each embodiment can be combined in any manner. The present application is not limited to the specific embodiments disclosed in this specification, but includes all technical solutions within the scope of the claims.
