Description

Technical Field

[0001] The present application relates to the field of semiconductor packaging technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) display technology is regarded as the most promising new flat panel display technology of the next generation. Compared with liquid crystal display technology, OLED display technology has the advantages of low energy consumption, low cost, self-luminescence, wide viewing angle and fast response speed.

[0003] In the process of traditional display panel preparation, the graphicization of luminous pixels is usually achieved through a fine metal mask (FMM). FMM technology is mature and has rich experience in mass production. However, FMM technology also has problems such as limited precision, high development cost, and long development cycle. The fine metal mask-free technology eliminates the limitations of traditional OLED processes on display screen size, resolution, and other screen performance, and has the advantages of high performance, full-domain size, and agile delivery.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0076] In the related art, the connection performance between the electrode and the auxiliary electrode of the light emitting device of the OLED display panel is poor, resulting in poor display.

[0077] In view of the above problems, embodiments of the present application provide a display panel and a display device capable of improving the display defect problem.

[0078] Combination Figure 1-Figure 16 As shown, an embodiment of the present application provides a display panel 100, which may be an organic light emitting diode display panel 100 (Organic Light Emitting Diode, referred to as OLED) or a quantum dot electroluminescent display panel 100 (Quantum Dot Light Emitting Diodes, referred to as QLED).

[0079] Specifically, the display panel 100 includes: an array substrate 1, an isolation structure 2a and a device layer 3. The isolation structure 2a is located on one side of the array substrate 1, and includes a first conductive layer 21; the first conductive layer 21 encloses a plurality of first openings 21a; the plurality of first openings 21a are arranged into a plurality of opening rows along a first direction X, and are arranged into a plurality of opening columns along a second direction Y, and the first direction X and the second direction Y intersect; at least one protrusion 212 is convexly provided on a part of the wall surface of each first opening 21a. In other words, the first conductive layer 21 includes a non-protruding portion 211 and a protruding portion 212, and the non-protruding portion 211 and the protruding portion 212 enclose the first opening 21a. The device layer 3 is located on one side of the array substrate 1; the device layer 3 includes a plurality of light-emitting structures 31-1, the isolation structure 2a is located between two adjacent light-emitting structures 31-1, and the plurality of light-emitting structures 31-1 are arranged in one-to-one correspondence with the plurality of first openings 21a; at least part of the orthographic projection of the light-emitting structure 31-1 on the array substrate 1 is located within the orthographic projection of the wall of the first opening 21a on the array substrate 1; the light-emitting structure 31-1 includes a stacked sub-light-emitting portion 3121 and a sub-electrode portion 3131.

[0080] The sub-electrode portion 3131 is connected to the protrusion 212, and the orthographic projection of the sub-electrode portion 3131 on the array substrate 1 overlaps with at least a portion of the orthographic projection of the protrusion 212 on the array substrate 1. That is, part of the structure of the sub-electrode portion 3131 is placed on the protrusion 212 to achieve connection with the protrusion 212.

[0081] In the embodiment of the present application, the first conductive layer 21 is patterned so that the first conductive layer 21 encloses and forms a first opening 21a, and at least one protrusion 212 is convexly provided on a part of the wall surface of the first opening 21a, so that the sub-electrode portion 3131 of the light-emitting structure 31-1 can be conveniently overlapped with the protrusion 212. In this way, the first conductive layer 21 is equivalent to the auxiliary electrode, which is equivalent to protruding the protrusion 212 on the wall surface of the first opening 21a, which not only reduces the connection difficulty between the sub-electrode portion 3131 and the auxiliary electrode, improves the reliability of electrical connection, but also reduces the electrical connection resistance between the two, thereby improving the display effect. In addition, by arranging a plurality of first openings 21a into a plurality of opening rows along the first direction X, and arranging them into a plurality of opening columns along the second direction Y, the first openings 21a and the protrusions 212 can be arranged more regularly, so that the pattern of the first conductive layer 21 is more regular, which is conducive to improving the etching uniformity during the etching of the first conductive layer 21.

[0082] In one embodiment, in the same opening row, the number of protrusions 212 in each first opening 21a is the same. Thus, in the same row, the number of protrusions 212 connected to the sub-electrode portions 3131 of each light-emitting structure 31-1 is equal, which is conducive to ensuring the uniformity of the lap resistance and thus improving the display uniformity.

[0083] In one embodiment, in the same row of openings, the number of protrusions 212 in each first opening 21a is the same. Thus, in the same row, the number of protrusions 212 connected to the sub-electrode portions 3131 of each light-emitting structure 31-1 is equal, which helps to ensure the uniformity of the lap resistance and further improve the display uniformity.

[0084] In one embodiment, a protrusion 212 is provided on at least one side wall of the first opening 21a along the first direction X. In one example, a protrusion 212 is provided on a certain side wall of the first opening 21a along the first direction X. In another example, a protrusion 212 is provided on both side wall surfaces of the first opening 21a along the first direction X.

[0085] In one embodiment, a protrusion 212 is provided on at least one side wall of the first opening 21a along the second direction Y. In one example, a protrusion 212 is provided on a certain side wall of the first opening 21a along the second direction Y. In another example, a protrusion 212 is provided on both side walls of the first opening 21a along the second direction Y.

[0086] Optionally, the first direction X and the second direction Y are perpendicular.

[0087] In one embodiment, if Figure 1 As shown, in the same opening column, the protrusions 212 in all the first openings 21a are arranged into a protrusion column M along the second direction Y. In other words, all the protrusions 212 corresponding to the same opening column are arranged into a column along the second direction Y. In this way, it is beneficial to keep all the sub-electrode portions 3131 in the same opening column overlapped consistently, thereby ensuring the uniformity of the overlap resistance, and further improving the display uniformity.

[0088] Optionally, each protrusion 212 in the protrusion column M is located on the same side wall surface of the first opening 21a along the first direction X. This helps to keep all the sub-electrode portions 3131 in the same opening column overlapped consistently, thereby ensuring the uniformity of the overlap resistance and further improving the display uniformity.

[0089] In one embodiment, if Figure 4As shown, in the same opening column, the protrusions 212 in all the first openings 21a are arranged into two protrusion columns M along the second direction Y. In this way, it is equivalent to having two protrusions 212 protruding on the wall surface of the first opening 21a. By providing two protrusions 212, the contact area between the sub-electrode portion 3131 and the protrusion 212 can be increased, thereby reducing the lap resistance and improving the lap reliability.

[0090] In one embodiment, if Fig.10 As shown, each first opening 21a has a protrusion 212; in the same opening column, all the protrusions 212 in the first openings 21a in odd rows are arranged into a protrusion column M, and all the protrusions 212 in the first openings 21a in even rows are arranged into another protrusion column M.

[0091] In this way, it is equivalent to making the overlapping directions of the light-emitting structures 31-1 of two adjacent rows different, the light-emitting structures 31-1 of odd rows are overlapped on the left, and the light-emitting structures 31-1 of even rows are overlapped on the right. In this way, the overlapping scheme of the light-emitting structure 31-1 is designed differently. In this way, the uneven overlapping phenomenon caused by different scanning directions of specific evaporation equipment can be avoided. For example, when the sub-electrode parts 3131 of odd rows are evaporated, they are scanned from left to right, and the sub-electrode parts 3131 and the protrusions 212 are well overlapped; when the sub-electrode parts 3131 of even rows are evaporated, they are scanned from right to left, and the sub-electrode parts 3131 and the protrusions 212 are well overlapped; the above settings make it easy for designers to adjust the evaporation process (such as scanning direction) of each row of sub-electrode parts 3131 according to actual conditions, so as to improve the uneven brightness caused by uneven overlap.

[0092] In one embodiment, if Fig.11 As shown, each first opening 21a has a protrusion 212 disposed therein. In the same opening row, the protrusions 212 in one protrusion row M and the protrusions 212 in another protrusion row M are arranged in a staggered manner in the first direction X.

[0093] Optionally, in the same protrusion column M, at least two adjacent protrusions 212 form a group, and the distance between any two protrusions 212 in the same group is smaller than the distance between any two adjacent groups. Fig.11 For example, in the leftmost opening column, in a protrusion column M located on the right, the two protrusions 212 shown in the figure are a group, and the distance between the protrusions 212 in this group and other adjacent groups not shown in the figure is greater than the distance between the two protrusions 212. This arrangement is conducive to avoiding the regular mura phenomenon caused by uneven overlap of a fixed rule, and improves the display effect.

[0094] In one embodiment, if Figure 4As shown, two protrusions 212 are disposed in each first opening 21 a , and the two protrusions 212 are disposed opposite to each other along the first direction X.

[0095] Optionally, in the same opening column, the protrusions 212 in one protrusion column M are arranged opposite to the protrusions 212 in another protrusion column M in the first direction X. By making the two protrusions 212 opposite to each other in the first direction X, during the evaporation process, the sub-electrode portion 3131 can be overlapped with both protrusions 212 by only one evaporation.

[0096] In one embodiment, if Figure 1 , Figure 4 , Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown, in the same opening row, the protrusions 212 in each first opening 21a have the same size along the second direction Y, and the light emitting structures 31-1 corresponding to each first opening 21a have the same size along the second direction Y. The size of the light emitting structure 31-1 along the second direction Y is equivalent to the length of the light emitting structure 31-1, and the size of the protrusion 212 along the second direction Y is equivalent to the length of the protrusion 212.

[0097] This helps to keep all the sub-electrode portions 3131 in the same opening column overlapped consistently, thereby ensuring the uniformity of the overlap resistance and further improving the display uniformity.

[0098] In one embodiment, if Figure 1 and Figure 4 As shown, in the same row of openings, the protrusions 212 in the first openings 21a have the same size along the second direction Y, and the light emitting structures 31-1 corresponding to the first openings 21a have the same size along the second direction Y. This helps to keep all the sub-electrode portions 3131 in the same row of openings overlapped consistently, thereby helping to ensure the uniformity of the overlap resistance, thereby improving display uniformity.

[0099] In one embodiment, if Fig. 9 As shown, in two first openings 21a that are at least partially adjacent to each other in the same opening column, the size of the protrusion 212 in one first opening 21a along the second direction Y is not equal to the size of the protrusion 212 in the other first opening 21a along the second direction Y, and the size of the light-emitting structure 31-1 corresponding to one first opening 21a along the second direction Y is not equal to the size of the protrusion 212 in the other first opening 21a along the second direction Y.

[0100] It is understandable that the length of the protrusion 212 matches the length of the light emitting structure 31 - 1 , that is, the protrusion 212 corresponding to the longer light emitting structure 31 - 1 is also longer, and the protrusion 212 corresponding to the shorter light emitting structure 31 - 1 is also shorter.

[0101] In this way, on the one hand, it is convenient for designers to carry out differentiated design of the light-emitting structure 31-1 to meet design requirements; on the other hand, the light-emitting area of ​​the light-emitting structure 31-1 can be differentiated (irregularized), and the overlapping areas of different light-emitting structures 31-1 can be differentiated (irregularized), which is conducive to weakening the display unevenness caused by poor overlapping of some light-emitting structures 31-1 due to the process.

[0102] In one embodiment, if Fig.12 and Fig.13 As shown, the device layer 3 also includes a plurality of first electrodes 311, each of which is arranged corresponding to at least two light-emitting structures 31-1, and the first electrode 311 is arranged between the corresponding light-emitting structure 31-1 and the array substrate 1. The orthographic projection of the first electrode 311 on the array substrate 1 covers the orthographic projection of the corresponding light-emitting structure 31-1 on the array substrate 1, and the orthographic projection of the non-protruding portion 211 between the corresponding light-emitting structures 31-1 on the array substrate 1. Here, the first electrode 311 is an anode, and the sub-electrode portion 3131 is equivalent to a cathode. It can be understood that the first electrode 311 is electrically connected to the pixel circuit.

[0103] In this way, at least two light-emitting structures 31-1 share the same first electrode 311 and are electrically connected to the same pixel circuit. In this way, the at least two light-emitting structures 31-1 and the first electrode 311 are equivalent to a light-emitting device 31. In other words, it is equivalent to dividing the light-emitting device 31 into multiple light-emitting structures 31-1. When a light-emitting structure 31-1 fails (such as dark spot failure caused by particle residue, packaging failure, etc.), it will not affect other light-emitting structures 31-1. Other light-emitting structures 31-1 can still emit light normally, thereby reducing the risk of poor display of the display panel 100.

[0104] Optionally, each first electrode 311 is disposed corresponding to at least two light emitting structures 31 - 1 arranged adjacent to each other along the second direction Y. This is equivalent to dividing the light emitting device 31 along the first direction X.

[0105] It should be noted that in Figure 1 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11In order to illustrate the overlapping manner of the sub-electrode portion 3131 and the protrusion 212, in the above figure, only the sub-electrode portion 3131 of the light-emitting structure 31-1 is indicated by a number. It can be understood that the contour morphology of the sub-electrode portion 3131 is the same as the contour morphology of the light-emitting structure 31-1, and the outer dimensions of the sub-electrode portion 3131 are equal to the outer dimensions of the light-emitting structure 31-1. Therefore, in the above figure, the sub-electrode portion 3131 can also be considered as the light-emitting structure 31-1.

[0106] Optionally, refer to Fig. 9 As shown, in at least two light-emitting structures 31-1 corresponding to the same first electrode 311, the sizes of the light-emitting structures 31-1 along the second direction Y are different. That is, in at least two light-emitting structures 31-1 corresponding to the same first electrode 311, the sizes of the sub-electrode parts 3131 of the light-emitting structures 31-1 along the second direction Y are different. In at least two light-emitting structures 31-1 corresponding to the same first electrode 311, the sizes of the protrusions 212 connected to the light-emitting structures 31-1 along the second direction Y are different. The size of the light-emitting structure 31-1 along the second direction Y is equivalent to the length of the light-emitting structure 31-1, and the size of the protrusion 212 along the second direction Y is equivalent to the length of the protrusion 212. It can be understood that the length of the protrusion 212 is adapted to the length of the light-emitting structure 31-1. That is, the protrusion 212 corresponding to the light-emitting structure 31-1 with a longer length is also longer, and the protrusion 212 corresponding to the light-emitting structure 31-1 with a shorter length is also shorter.

[0107] In this way, the light emitting device 31 includes at least two light emitting structures 31-1 of different lengths. On the one hand, it is convenient for designers to differentiate the light emitting structures 31-1 to meet design requirements; on the other hand, the light emitting areas of the light emitting structures 31-1 can be differentiated (irregularized), and the overlapping areas of different light emitting structures 31-1 can be differentiated (irregularized), which is conducive to weakening the display unevenness caused by poor overlapping of some light emitting structures 31-1 due to the process.

[0108] Optionally, refer to Figure 1 , Figure 4 and Figure 7 As shown, in at least two light-emitting structures 31-1 corresponding to the same first electrode 311, the dimensions of each light-emitting structure 31-1 along the second direction Y are the same, that is, the lengths of each light-emitting structure 31-1 are the same; in at least two light-emitting structures 31-1 corresponding to the same first electrode 311, the dimensions of the protrusions 212 connected to each light-emitting structure 31-1 along the second direction Y are the same, that is, the lengths of each protrusion 212 are the same.

[0109] In this way, the light emitting structures 31 - 1 can be arranged more regularly, which is helpful to reduce the difficulty of typesetting and manufacturing for designers.

[0110] It should be noted that the same in the embodiments of the present application may also be considered to be approximately the same, and equal may also be considered to be approximately equal.

[0111] In one embodiment, the plurality of opening rows include a plurality of first rows L1, a plurality of second rows L2, and a plurality of third rows L3, and the first rows L1, the second rows L2, and the third rows L3 are alternately arranged in sequence along the first direction X; Figure 1 , Figure 4 and Figure 7 As shown, in the first column L1, the second column L2 and the third column L3, at least two columns have the same number of first openings 21a, so that designers can design the light emitting structures 31-1 in each column differently to meet design requirements.

[0112] Alternatively, if Figure 1 and Figure 4 As shown, the number of the first openings 21 a in the first column L1 , the number of the first openings 21 a in the second column L2 , and the number of the first openings 21 a in the third column L3 are all the same.

[0113] Alternatively, if Figure 7 As shown, the number of the first openings 21 a in the first column L1 is the same as the number of the first openings 21 a in the third column L3 , and the number of the first openings 21 a in the first column L1 is different from the number of the first openings 21 a in the second column L2 .

[0114] Optionally, the number of the first openings 21 a in the first column L1 , the number of the first openings 21 a in the second column L2 , and the number of the first openings 21 a in the third column L3 are different.

[0115] Optionally, in the first column L1, two or three light emitting structures 31-1 arranged adjacent to each other along the second direction Y are disposed corresponding to the same first electrode 311. Specifically, Figure 1 , Figure 4 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, two light emitting structures 31-1 arranged adjacent to each other along the second direction Y are arranged corresponding to the same first electrode 311, that is, the light emitting device 31 of the first column L1 is divided into two light emitting structures 31-1, that is, the light emitting portion 312 of the light emitting device 31 is divided into two sub-light emitting portions 3121, and the second electrode 313 of the light emitting device 31 is divided into two sub-electrode portions 3131. Figure 8As shown, three light emitting structures 31 - 1 adjacently arranged along the second direction Y are disposed corresponding to the same first electrode 311 , that is, the light emitting device 31 of the first column L1 is divided into three light emitting structures 31 - 1 .

[0116] Optionally, in the second column L2, two or three light emitting structures 31-1 arranged adjacent to each other along the second direction Y are disposed corresponding to the same first electrode 311. Specifically, Figure 1 , Figure 4 , Fig. 9 , Fig.10 and Fig.11 As shown, two light emitting structures 31-1 arranged adjacent to each other along the second direction Y are arranged corresponding to the same first electrode 311, that is, the light emitting device 31 of the second column L2 is divided into two light emitting structures 31-1. Figure 7 and Figure 8 As shown, three light emitting structures 31 - 1 adjacently arranged along the second direction Y are disposed corresponding to the same first electrode 311 , that is, the light emitting device 31 of the second column L2 is divided into three light emitting structures 31 - 1 .

[0117] Optionally, in the third column L3, two or three light emitting structures 31-1 arranged adjacent to each other along the second direction Y are disposed corresponding to the same first electrode 311. Specifically, Figure 1 , Figure 4 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, two light emitting structures 31-1 arranged adjacent to each other along the second direction Y are arranged corresponding to the same first electrode 311, that is, the light emitting device 31 of the third column L3 is divided into two light emitting structures 31-1. Figure 8 As shown, three light emitting structures 31 - 1 adjacently arranged along the second direction Y are disposed corresponding to the same first electrode 311 , that is, the light emitting device 31 of the third column L3 is divided into three light emitting structures 31 - 1 .

[0118] Alternatively, if Figure 1 and Figure 4 As shown, in the first column L1, two light emitting structures 31-1 arranged adjacent to each other along the second direction Y are arranged corresponding to the same first electrode 311; in the second column L2, two light emitting structures 31-1 arranged adjacent to each other along the second direction Y are arranged corresponding to the same first electrode 311; in the third column L3, two light emitting structures 31-1 arranged adjacent to each other along the second direction Y are arranged corresponding to the same first electrode 311. In this way, all the light emitting devices 31 are divided into two light emitting structures 31-1.

[0119] Alternatively, if Figure 7As shown, in the first column L1, two light emitting structures 31-1 arranged adjacently along the second direction Y are arranged correspondingly to the same first electrode 311; in the second column L2, three light emitting structures 31-1 arranged adjacently along the second direction Y are arranged correspondingly to the same first electrode 311; in the third column L3, two light emitting structures 31-1 arranged adjacently along the second direction Y are arranged correspondingly to the same first electrode 311. In this way, it is equivalent to dividing the light emitting device 31 of the first column L1 into two light emitting structures 31-1, dividing the light emitting device 31 of the second column L2 into three light emitting structures 31-1, and dividing the light emitting device 31 of the third column L3 into two light emitting structures 31-1.

[0120] Alternatively, if Figure 8 As shown, in the first column L1, three light emitting structures 31-1 arranged adjacently along the second direction Y are arranged correspondingly to the same first electrode 311; in the second column L2, three light emitting structures 31-1 arranged adjacently along the second direction Y are arranged correspondingly to the same first electrode 311; in the third column L3, three light emitting structures 31-1 arranged adjacently along the second direction Y are arranged correspondingly to the same first electrode 311. In this way, all the light emitting devices 31 are divided into three light emitting structures 31-1.

[0121] Optionally, the light emitting structures 31 - 1 corresponding to the first openings 21 a in the same column emit the same light color.

[0122] Optionally, the two columns of light emitting structures 31 - 1 corresponding to any two adjacent columns of first openings 21 a have different light emitting colors. In this way, the light emitting structures 31 - 1 of different colors can be staggered in the first direction X, which is beneficial to improving the display effect.

[0123] Specifically, the light emitting colors of the light emitting structures 31-1 corresponding to the first column L1, the light emitting colors of the light emitting structures 31-1 corresponding to the second column L2, and the light emitting colors of the light emitting structures 31-1 corresponding to the third column L3 are different. Specifically, the light emitting structures 31-1 in the first column L1 are any one of a red light emitting structure, a blue light emitting structure, and a green light emitting structure, the light emitting structures 31-1 in the second column L2 are any one of a red light emitting structure, a blue light emitting structure, and a green light emitting structure, and the light emitting structures 31-1 in the third column L3 are any one of a red light emitting structure, a blue light emitting structure, and a green light emitting structure.

[0124] In one embodiment, in at least two light emitting structures 31 - 1 corresponding to the same first electrode 311 , the thickness of the sub-electrode portion 3131 of one light emitting structure 31 - 1 is not equal to the thickness of the sub-electrode portion 3131 of another light emitting structure 31 - 1 .

[0125] It should be noted that when the overlapping directions of two adjacent sub-electrode portions 3131 of the same light-emitting device 31 are different, the overlapping resistance of the two sub-electrode portions 3131 may be different. By differentially setting the thickness of the two sub-electrode portions 3131, it helps to balance the overlapping resistance of the two sub-electrode portions 3131 and improve display uniformity.

[0126] In one embodiment, in at least two light emitting structures 31 - 1 corresponding to the same first electrode 311 , the thicknesses of the sub-electrode portions 3131 of the light emitting structures 31 - 1 are all equal.

[0127] In one embodiment, if Fig.10 and Fig.11 As shown, the plurality of opening rows include a plurality of first rows H1 and a plurality of second rows H2 , and the first rows H1 and the second rows H2 are arranged along the second direction Y alternately.

[0128] In the first row H1, the protrusions 212 in each first opening 21a are located on one side wall of the first opening 21a along the first direction X; in other words, the protrusions 212 in the first row H1 are located on the left side wall of the first opening 21a. In the second row H2, the protrusions 212 in each first opening 21a are located on the other side wall of the first opening 21a along the first direction X; in other words, the protrusions 212 in the second row H2 are located on the right side wall of the first opening 21a.

[0129] In this way, it is equivalent to making the overlapping directions of the light-emitting structures 31-1 in two adjacent rows different. The light-emitting structures 31-1 in the first row H1 are overlapped on the left, and the light-emitting structures 31-1 in the second row H2 are overlapped on the right. In this way, the overlapping schemes of the light-emitting structures 31-1 are designed differently. In this way, the uneven overlapping phenomenon caused by different scanning directions of specific evaporation equipment can be avoided. For example, when the sub-electrode portion 3131 of the first row H1 is evaporated, it is scanned from left to right, and the sub-electrode portion 3131 and the protrusion 212 overlap well; when the sub-electrode portion 3131 of the second row H2 is evaporated, it is scanned from right to left, and the sub-electrode portion 3131 and the protrusion 212 overlap well; the above-mentioned setting makes it easy for designers to adjust the evaporation process (such as scanning direction) of each row of sub-electrode portions 3131 according to actual conditions, so as to improve the uneven brightness caused by uneven overlapping.

[0130] Alternatively, if Fig.10 As shown, the first row H1 and the second row H2 are arranged alternately along the second direction Y in sequence.

[0131] Alternatively, if Fig.11As shown, the plurality of opening rows further include a plurality of third rows H3 and a plurality of fourth rows H4, and the first row H1, the second row H2, the third row H3 and the fourth row H4 are arranged alternately in sequence along the second direction Y. In the fourth row H4, the protrusions 212 in each first opening 21a are all located on one side wall of the first opening 21a along the first direction X; in other words, the protrusions 212 in the fourth row H4 are all located on the left side wall of the first opening 21a. In the third row H3, the protrusions 212 in each first opening 21a are all located on the other side wall of the first opening 21a along the first direction X; in other words, the protrusions 212 in the third row H3 are all located on the right side wall of the first opening 21a.

[0132] Furthermore, the light emitting structure 31-1 in the first row H1 and the light emitting structure 31-1 in the second row H2 constitute a light emitting device 31, the light emitting structure 31-1 in the third row H3 and the light emitting structure 31-1 in the fourth row H4 constitute a light emitting device 31, and the overlapping rules of the two adjacent light emitting devices 31 in the second direction Y are different. In this way, it is helpful to avoid the regular mura phenomenon caused by uneven overlapping of fixed rules, and improve the display effect.

[0133] Optionally, in the same row of first openings 21a, the three adjacent first openings 21a respectively correspond to light emitting structures 31-1 of different light emitting colors. Specifically, the three light emitting structures 31-1 corresponding to the three adjacent first openings 21a are respectively a red light emitting structure, a green light emitting structure and a blue light emitting structure.

[0134] In one of the embodiments, the orthographic projection of the sub-light emitting portion 3121 on the array substrate 1 overlaps with at least a portion of the orthographic projection of the protruding portion 212 on the array substrate 1 .

[0135] In one embodiment, the orthographic projection of the sub-light emitting portion 3121 on the array substrate 1 is located outside the orthographic projection of the protruding portion 212 on the array substrate 1. This is helpful to improve the leakage phenomenon.

[0136] In one embodiment, referring to Fig.12 , Fig.13 and Fig.14 As shown, the isolation structure 2a also includes a second conductive layer 22 and a blocking layer 23 stacked on the first conductive layer 21, and the outer contour of the orthographic projection of the blocking layer 23 on the array substrate 1 is located outside the outer contour of the orthographic projection of the second conductive layer 22 on the array substrate 1; the orthographic projection of the first conductive layer 21 on the array substrate 1 is located within the range of the orthographic projection of the second conductive layer 22 on the array substrate 1.

[0137] Optionally, the orthographic projection of the protrusion 212 on the array substrate 1 is located within the orthographic projection range of the blocking layer 23 on the array substrate 1 .

[0138] In one example, the material of the first conductive layer 21 may be molybdenum, the material of the second conductive layer 22 may be aluminum, and the material of the barrier layer 23 may be titanium or molybdenum.

[0139] Optionally, the display panel 100 further includes a pixel defining layer 4, which is located between the array substrate 1 and the first conductive layer 21 and encloses a plurality of sub-pixel openings 4a1; the plurality of sub-pixel openings 4a1 are connected to the plurality of first openings 21a in a one-to-one correspondence. Further, the pixel defining layer 4 is disposed between the array substrate 1 and the first conductive layer 21. It is understood that the set of all sub-pixel openings 4a1 corresponding to the same light-emitting device 31 can be considered as the pixel opening 4a corresponding to the light-emitting device 31.

[0140] In one embodiment, referring to Figure 12-16 As shown, the device layer 3 includes a plurality of light-emitting devices 31, and the plurality of light-emitting devices 31 include a plurality of first light-emitting devices 31a, a plurality of second light-emitting devices 31b, and a plurality of third light-emitting devices 31c. The light emitted by the first light-emitting device 31a, the second light-emitting device 31b, and the third light-emitting device 31c are different in color. The isolation layer 2 is located on the side of the pixel defining layer 4 away from the array substrate 1, and includes an isolation structure 2a and a plurality of isolation openings 2b formed by the isolation structure 2a. The plurality of isolation openings 2b include a plurality of first isolation openings 2b-1, a plurality of second isolation openings 2b-2, and a plurality of third isolation openings 2b-3. The first light-emitting device 31a is correspondingly arranged with the first isolation opening 2b-1, the second light-emitting device 31b is correspondingly arranged with the second isolation opening 2b-2, and the third light-emitting device 31c is correspondingly arranged with the third isolation opening 2b-3. Among the first light-emitting device 31a, the second light-emitting device 31b, and the third light-emitting device 31c, the light-emitting portion 312 of the light-emitting device 31 of at least one color includes a plurality of sub-light-emitting portions 3121.

[0141] In this way, it is equivalent to dividing the light-emitting portion 312 of the same color into multiple sub-light-emitting portions 3121, which is beneficial to keep the light-emitting portions 312 of the same color consistent and to improve display uniformity.

[0142] Optionally, in the first light emitting device 31 a , the second light emitting device 31 b and the third light emitting device 31 c , the light emitting portion 312 of at least two color light emitting devices 31 includes a plurality of sub-light emitting portions 3121 .

[0143] In this way, compared with the method of segmenting the light-emitting portion 312 of only one color, the present embodiment segments the light-emitting portion 312 of at least two colors, so that the light-emitting portions 312 of the two colors can overcome the poor display problem caused by failure (such as dark spot failure caused by particle residue, packaging failure, etc.), thereby further reducing the risk of poor display.

[0144] Optionally, in the first light emitting device 31a, the second light emitting device 31b and the third light emitting device 31c, the light emitting portion 312 of all the light emitting devices 31 includes a plurality of sub-light emitting portions 3121. In this way, the light emitting portions 312 of the three colors can all overcome the display failure caused by failure (such as dark spot failure caused by particle residue, packaging failure, etc.), further reducing the risk of display failure.

[0145] In one embodiment, the wavelength of light emitted by the first light-emitting device 31a is between 600nm and 650nm; the light-emitting portion 312 of the first light-emitting device 31a includes a plurality of sub-light-emitting portions 3121, the first isolation opening 2b-1 includes a plurality of first sub-isolation openings 2b1-1, and the second electrode 313 of the first light-emitting device 31a includes a plurality of first sub-electrode portions 3131a corresponding one-to-one to the plurality of first sub-isolation openings 2b1-1; the orthographic projection of the first sub-electrode portion 3131a corresponding to the first sub-isolation opening 2b1-1 on the array substrate 1 overlaps with the orthographic projection of the protrusion 212 corresponding to the first sub-isolation opening 2b1-1 on the array substrate 1.

[0146] Optionally, a plurality of sub-light emitting portions 3121 of the same first light emitting device 31a are arranged at intervals along the second direction Y; all protrusions 212 corresponding to the first light emitting device 31a are located on at least one side of the light emitting portion 312 of the first light emitting device 31a along the first direction X. Figure 1 As shown, all the protrusions 212 corresponding to the first light emitting device 31a are located on the left side of the center of the first sub-electrode portion 3131a. Figure 4 As shown, all the protrusions 212 corresponding to the first light emitting device 31 a are evenly arranged on the left and right sides of the center of the first sub-electrode portion 3131 a (the second electrode 313 ).

[0147] Optionally, in the same first light-emitting device 31a, the sizes of each sub-light-emitting portion 3121 along the second direction Y are equal, the sizes of each first sub-electrode portion 3131a along the second direction Y are equal; the sizes of each protrusion 212 corresponding to the first light-emitting device 31a along the second direction Y are equal.

[0148] Optionally, in the same first light-emitting device 31a, the sizes of two adjacent sub-light-emitting portions 3121 along the second direction Y are unequal, and the sizes of the first sub-electrode portions 3131a corresponding to the two adjacent sub-light-emitting portions 3121 along the second direction Y are unequal.

[0149] For example, in the first light emitting device 31a, the length of the sub-light emitting portion 3121 located in the first row H1 is greater than the length of the sub-light emitting portion 3121 located in the second row H2, and the length of the sub-light emitting portion 3121 located in the third row H3 is less than the length of the sub-light emitting portion 3121 located in the fourth row H4. Fig. 9 As shown, the length of the first sub-electrode portion 3131a in the first row H1 is greater than the length of the first sub-electrode portion 3131a in the second row H2. The length of the first sub-electrode portion 3131a in the third row H3 is less than the length of the first sub-electrode portion 3131a in the fourth row H4.

[0150] Optionally, in two adjacent sub-light emitting portions 3121 of the same first light emitting device 31a, the size of the protrusion 212 corresponding to one sub-light emitting portion 3121 along the second direction Y is not equal to the size of the protrusion 212 corresponding to the other sub-light emitting portion 3121 along the second direction Y. Fig. 9 As shown, in the first light-emitting device 31a, the length of the protrusion 212 located in the first row H1 is greater than the length of the protrusion 212 located in the second row H2, and the length of the protrusion 212 located in the third row H3 is less than the length of the protrusion 212 located in the fourth row H4. The above arrangement can match the length of the protrusion 212 with the length of the first sub-electrode portion 3131a, which is beneficial to maximally reduce the overlap resistance and improve the display effect.

[0151] In one embodiment, all the protrusions 212 corresponding to the first light emitting device 31a are located on the same side of the light emitting portion 312 of the first light emitting device 31a along the first direction X. Figure 1 As shown, all the protrusions 212 corresponding to the first light emitting device 31 a are located on the same side of the center of the first sub-electrode portion 3131 a of the first light emitting device 31 a.

[0152] Alternatively, all protrusions 212 corresponding to the first light emitting device 31a are located on both sides of the light emitting portion 312 of the first light emitting device 31a along the first direction X; and each sub-light emitting portion 3121 of the first light emitting device 31a is provided with a protrusion 212 on both sides along the first direction X. Figure 4 As shown, in the first light emitting device 31 a , protrusions 212 are provided on both left and right sides of the center of each first sub-electrode portion 3131 a .

[0153] In one embodiment, all the protrusions 212 corresponding to the first light emitting device 31a are located on both sides of the light emitting portion 312 of the first light emitting device 31a along the first direction X; in two adjacent sub-light emitting portions 3121 of the first light emitting device 31a, the two protrusions 212 corresponding to the two sub-light emitting portions 3121 are respectively located on both sides of the light emitting portion 312 of the first light emitting device 31a along the first direction X. Fig.10 and Fig.11 As shown, in the same first light-emitting device 31a, the first light-emitting device 31a corresponds to two protrusions 212, the protrusion 212 of the first row H1 is located on the left side of the center of the first sub-electrode portion 3131a, and the protrusion 212 of the second row H2 is located on the right side of the center of the first sub-electrode portion 3131a.

[0154] Optionally, the plurality of first light emitting devices 31 a are arranged in columns along the second direction Y, and in rows along the first direction X.

[0155] In two first light emitting devices 31a adjacent to each other along the second direction Y, a sub-light emitting portion 3121 of one first light emitting device 31a is adjacent to a sub-light emitting portion 3121 of another first light emitting device 31a, and two protrusions 212 corresponding to the two adjacent sub-light emitting portions 3121 are respectively located on both sides of the two first light emitting devices 31a along the first direction X. Fig.10 As shown, the first sub-electrode portion 3131a of the second row H2 is adjacent to the first sub-electrode portion 3131a of the third row H3, and the two belong to different light-emitting devices 31 respectively. The protrusion 212 of the second row H2 is located on the right side of the center of the first sub-electrode portion 3131a, and the protrusion 212 of the third row H3 is located on the left side of the center of the first sub-electrode portion 3131a.

[0156] In this way, the overlapping manners of all the first light-emitting devices 31 a can be made consistent, which is beneficial for designers to perform layout design and is beneficial for reducing production costs.

[0157] Alternatively, in two first light emitting devices 31a adjacent to each other along the second direction Y, a sub-light emitting portion 3121 of one first light emitting device 31a is adjacent to a sub-light emitting portion 3121 of another first light emitting device 31a, and two protrusions 212 corresponding to the two adjacent sub-light emitting portions 3121 are located on the same side of the two first light emitting devices 31a along the first direction X. Fig.11 As shown, the first sub-electrode portion 3131a of the second row H2 is adjacent to the first sub-electrode portion 3131a of the third row H3, and the two belong to different light-emitting devices 31 respectively. The protrusion 212 of the second row H2 is located on the right side of the center of the first sub-electrode portion 3131a, and the protrusion 212 of the third row H3 is located on the right side of the center of the first sub-electrode portion 3131a.

[0158] This helps to avoid the regular mura phenomenon caused by uneven overlapping of fixed rules, thereby improving the display effect.

[0159] In one embodiment, the wavelength of light emitted by the second light emitting device 31b is between 505nm and 545nm; the light emitting portion 312 of the second light emitting device 31b includes a plurality of sub-light emitting portions 3121, the second isolation opening 2b-2 includes a plurality of second sub-isolation openings 2b1-2, and the second electrode 313 of the second light emitting device 31b includes a plurality of second sub-electrode portions 3131b corresponding to the plurality of second sub-isolation openings 2b1-2. The orthographic projection of the second sub-electrode portion 3131b corresponding to the second sub-isolation openings 2b1-2 on the array substrate 1 overlaps with the orthographic projection of the protrusion 212 corresponding to the second sub-isolation openings 2b1-2 on the array substrate 1.

[0160] Optionally, a plurality of sub-light emitting portions 3121 of the same second light emitting device 31b are arranged at intervals along the second direction Y; all protrusions 212 corresponding to the second light emitting device 31b are located on at least one side of the light emitting portion 312 of the second light emitting device 31b along the first direction X. Figure 1 As shown, all the protrusions 212 corresponding to the second light emitting device 31b are located on the left side of the center of the second sub-electrode portion 3131b. Figure 4 As shown, all the protrusions 212 corresponding to the second light emitting device 31 b are evenly arranged on the left and right sides of the center of the second sub-electrode portion 3131 b (the second electrode 313 ).

[0161] Optionally, the number of sub-electrode portions 3121 in the second light-emitting device 31b is equal to or unequal to the number of sub-electrode portions 3121 in the first light-emitting device 31a. In other words, the number of second sub-electrode portions 3131b in the second light-emitting device 31b is equal to or unequal to the number of first sub-electrode portions 3131a in the first light-emitting device 31a. Figure 1 As shown, the number of the second sub-electrode portions 3131b in the second light-emitting device 31b is equal to the number of the first sub-electrode portions 3131a in the first light-emitting device 31a. Figure 7 As shown, the number of the second sub-electrode portions 3131b in the second light-emitting device 31b is three, and the number of the first sub-electrode portions 3131a in the first light-emitting device 31a is two.

[0162] Optionally, in the same second light-emitting device 31b, the sizes of the sub-light-emitting portions 3121 along the second direction Y are equal, the sizes of the second sub-electrode portions 3131b along the second direction Y are equal; the sizes of the protrusions 212 corresponding to the second light-emitting device 31b along the second direction Y are equal;

[0163] Optionally, in the same second light-emitting device 31b, the sizes of two adjacent sub-light-emitting portions 3121 along the second direction Y are unequal, and the sizes of the second sub-electrode portions 3131b corresponding to the two adjacent sub-light-emitting portions 3121 along the second direction Y are unequal.

[0164] For example, in the second light emitting device 31b, the length of the sub-light emitting portion 3121 located in the first row H1 is greater than the length of the sub-light emitting portion 3121 located in the second row H2, and the length of the sub-light emitting portion 3121 located in the third row H3 is less than the length of the sub-light emitting portion 3121 located in the fourth row H4. Fig. 9 As shown, the length of the second sub-electrode portion 3131b in the first row H1 is greater than the length of the second sub-electrode portion 3131b in the second row H2. The length of the second sub-electrode portion 3131b in the third row H3 is less than the length of the second sub-electrode portion 3131b in the fourth row H4.

[0165] Optionally, in two adjacent sub-light emitting portions 3121 of the same second light emitting device 31b, the size of the protrusion 212 corresponding to one sub-light emitting portion 3121 along the second direction Y is not equal to the size of the protrusion 212 corresponding to the other sub-light emitting portion 3121 along the second direction Y. Fig. 9 As shown, in the second light emitting device 31b, the length of the protrusion 212 located in the first row H1 is greater than the length of the protrusion 212 located in the second row H2, and the length of the protrusion 212 located in the third row H3 is less than the length of the protrusion 212 located in the fourth row H4. The above arrangement can match the length of the protrusion 212 with the length of the second sub-electrode portion 3131b, which is beneficial to maximally reduce the overlap resistance and improve the display effect.

[0166] In one embodiment, all the protrusions 212 corresponding to the second light emitting device 31b are located on the same side of the light emitting portion 312 of the second light emitting device 31b along the first direction X. Figure 1 As shown, all the protrusions 212 corresponding to the second light emitting device 31 b are located on the same side of the center of the second sub-electrode portion 3131 b of the second light emitting device 31 b.

[0167] Alternatively, all protrusions 212 corresponding to the second light emitting device 31b are located on both sides of the light emitting portion 312 of the second light emitting device 31b along the first direction X; and each sub-light emitting portion 3121 of the second light emitting device 31b is provided with a protrusion 212 on both sides along the first direction X. Figure 4 As shown, in the second light emitting device 31 b , protrusions 212 are provided on both left and right sides of the center of each second sub-electrode portion 3131 b .

[0168] In one embodiment, all the protrusions 212 corresponding to the second light emitting device 31b are located on both sides of the light emitting portion 312 of the second light emitting device 31b along the first direction X; in two adjacent sub-light emitting portions 3121 of the second light emitting device 31b, the two protrusions 212 corresponding to the two sub-light emitting portions 3121 are respectively located on both sides of the light emitting portion 312 of the second light emitting device 31b along the first direction X. Fig.10 and Fig.11 As shown, in the same second light-emitting device 31b, the second light-emitting device 31b corresponds to two protrusions 212, the protrusion 212 of the first row H1 is located on the left side of the center of the second sub-electrode portion 3131b, and the protrusion 212 of the second row H2 is located on the right side of the center of the second sub-electrode portion 3131b.

[0169] Optionally, the plurality of second light emitting devices 31 b are arranged in columns along the second direction Y, and are arranged in rows along the first direction X.

[0170] In two second light emitting devices 31b adjacent to each other along the second direction Y, a sub-light emitting portion 3121 of one second light emitting device 31b is adjacent to a sub-light emitting portion 3121 of another second light emitting device 31b, and two protrusions 212 corresponding to the two adjacent sub-light emitting portions 3121 are respectively located on both sides of the two second light emitting devices 31b along the first direction X. Fig.10 As shown, the second sub-electrode portion 3131b of the second row H2 is adjacent to the second sub-electrode portion 3131b of the third row H3, and the two belong to different light-emitting devices 31 respectively. The protrusion 212 of the second row H2 is located on the right side of the center of the second sub-electrode portion 3131b, and the protrusion 212 of the third row H3 is located on the left side of the center of the second sub-electrode portion 3131b.

[0171] In this way, the overlapping and misaligned modes of all the second light emitting devices 31 b can be made consistent, which is beneficial for designers to perform layout design and is beneficial for reducing production costs.

[0172] Alternatively, in two second light emitting devices 31b adjacent to each other along the second direction Y, a sub-light emitting portion 3121 of one second light emitting device 31b is adjacent to a sub-light emitting portion 3121 of another second light emitting device 31b, and two protrusions 212 corresponding to the two adjacent sub-light emitting portions 3121 are located on the same side of the two second light emitting devices 31b along the first direction X. Fig.11 As shown, the second sub-electrode portion 3131b of the second row H2 is adjacent to the second sub-electrode portion 3131b of the third row H3, and the two belong to different light-emitting devices 31 respectively. The protrusion 212 of the second row H2 is located on the right side of the center of the second sub-electrode portion 3131b, and the protrusion 212 of the third row H3 is located on the right side of the center of the second sub-electrode portion 3131b.

[0173] This helps to avoid the regular mura phenomenon caused by uneven overlapping of fixed rules, thereby improving the display effect.

[0174] In one embodiment, the wavelength of light emitted by the third light emitting device 31c is between 440nm and 480nm; the light emitting portion 312 of the third light emitting device 31c includes a plurality of sub-light emitting portions 3121, the third isolation opening 2b-3 includes a plurality of third sub-isolation openings 2b1-3, and the second electrode 313 of the third light emitting device 31c includes a plurality of third sub-electrode portions 3131c corresponding to the plurality of third sub-isolation openings 2b1-3. The orthographic projection of the third sub-electrode portion 3131c corresponding to the third sub-isolation openings 2b1-3 on the array substrate 1 overlaps with the orthographic projection of the protrusion 212 corresponding to the third sub-isolation openings 2b1-3 on the array substrate 1.

[0175] Optionally, a plurality of sub-light emitting portions 3121 of the same third light emitting device 31c are arranged at intervals along the second direction Y; all protrusions 212 corresponding to the third light emitting device 31c are located on at least one side of the light emitting portion 312 of the third light emitting device 31c along the first direction X. Figure 1 As shown, all the protrusions 212 corresponding to the third light emitting device 31c are located on the left side of the center of the third sub-electrode portion 3131c. Figure 4 As shown, all the protrusions 212 corresponding to the third light emitting device 31 c are evenly arranged on the left and right sides of the center of the third sub-electrode portion 3131 c (the second electrode 313 ).

[0176] Optionally, the number of sub-electrode portions 3121 in the third light-emitting device 31c is equal to or unequal to the number of sub-electrode portions 3121 in the second light-emitting device 31b. In other words, the number of second sub-electrode portions 3131b in the second light-emitting device 31b is equal to or unequal to the number of third sub-electrode portions 3131c in the third light-emitting device 31c. Figure 1 As shown, the number of the second sub-electrode portions 3131b in the second light-emitting device 31b is equal to the number of the third sub-electrode portions 3131c in the third light-emitting device 31c. Figure 7 As shown, the number of the second sub-electrode portions 3131b in the second light-emitting device 31b is three, and the number of the third sub-electrode portions 3131c in the third light-emitting device 31c is two.

[0179] For example, in the third light emitting device 31c, the length of the sub-light emitting portion 3121 located in the first row H1 is greater than the length of the sub-light emitting portion 3121 located in the second row H2, and the length of the sub-light emitting portion 3121 located in the third row H3 is less than the length of the sub-light emitting portion 3121 located in the fourth row H4. Fig. 9 As shown, the length of the third sub-electrode portion 3131c in the first row H1 is greater than the length of the third sub-electrode portion 3131c in the second row H2. The length of the third sub-electrode portion 3131c in the third row H3 is less than the length of the third sub-electrode portion 3131c in the fourth row H4.

[0180] Optionally, in two adjacent sub-light emitting portions 3121 of the same third light emitting device 31c, the size of the protrusion 212 corresponding to one sub-light emitting portion 3121 along the second direction Y is not equal to the size of the protrusion 212 corresponding to the other sub-light emitting portion 3121 along the second direction Y. Fig. 9 As shown, in the third light-emitting device 31c, the length of the protrusion 212 located in the first row H1 is greater than the length of the protrusion 212 located in the second row H2, and the length of the protrusion 212 located in the third row H3 is less than the length of the protrusion 212 located in the fourth row H4. The above arrangement can match the length of the protrusion 212 with the length of the third sub-electrode portion 3131c, which is beneficial to maximally reduce the overlap resistance and improve the display effect.

[0181] In one embodiment, all the protrusions 212 corresponding to the third light emitting device 31c are located on the same side of the light emitting portion 312 of the third light emitting device 31c along the first direction X. Figure 1 As shown, all the protrusions 212 corresponding to the third light emitting device 31c are located on the same side of the center of the third sub-electrode portion 3131c of the third light emitting device 31c.

[0182] Alternatively, all protrusions 212 corresponding to the third light emitting device 31c are located on both sides of the light emitting portion 312 of the third light emitting device 31c along the first direction X; and each sub-light emitting portion 3121 of the third light emitting device 31c is provided with a protrusion 212 on both sides along the first direction X. Figure 4 As shown, in the third light emitting device 31c, protrusions 212 are provided on both left and right sides of the center of each third sub-electrode portion 3131c.

[0183] In one embodiment, all protrusions 212 corresponding to the third light emitting device 31c are located on both sides of the light emitting portion 312 of the third light emitting device 31c along the first direction X; in two adjacent sub-light emitting portions 3121 of the third light emitting device 31c, the two protrusions 212 corresponding to the two sub-light emitting portions 3121 are respectively located on both sides of the light emitting portion 312 of the third light emitting device 31c along the first direction X.

[0186] In this way, the overlapping modes of all the third light emitting devices 31c can be made consistent, which is beneficial for designers to carry out layout design and is beneficial for reducing production costs.

[0187] Alternatively, in two third light emitting devices 31c adjacent to each other along the second direction Y, a sub-light emitting portion 3121 of one third light emitting device 31c is adjacent to a sub-light emitting portion 3121 of another third light emitting device 31c, and two protrusions 212 corresponding to the two adjacent sub-light emitting portions 3121 are located on the same side of the two third light emitting devices 31c along the first direction X.
