Description

Technical Field

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

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

[0003] In traditional display panel manufacturing, a fine metal mask (FMM) is typically used to pattern the light-emitting pixels. FMM technology is mature and has extensive mass production experience. However, FMM technology also suffers from limitations in precision, high development costs, and long development cycles. Fine metal mask-less technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance characteristics, offering advantages such as high performance, full-size display, and agile delivery. Patents CN118251982A, CN115666161A, CN116648095A, CN117062489A, CN118678742A, CN118785761A, CN115224220A, CN118678729A, CN118660529A, and CN118660589A describe relevant aspects of fine metal mask-less technology and are provided for reference.

[0004] However, current OLED display panels still suffer from display defects. Summary of the Invention

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0147] In related technologies, one or more light-emitting devices in an OLED display panel may fail, resulting in poor display quality.

[0148] In view of the above problems, embodiments of this application provide a display panel and display device. On the one hand, when one sub-part fails, it will not affect other sub-parts, and the other sub-parts can still emit light normally, thereby reducing the risk of display failure of the display panel. On the other hand, it allows designers to adaptively adjust the opening size according to actual needs, reducing design difficulty.

[0149] Reference Figures 1-11 As shown, this application embodiment provides a display panel 10, which may be an organic light-emitting diode display panel 10 (OLED) or a quantum dot light-emitting diode display panel 10 (QLED).

[0150] Specifically, the display panel 10 includes an array substrate 11, a pixel defining layer 15, an isolation layer 12, and a plurality of light-emitting portions 132. The pixel defining layer 15 is disposed on one side of the array substrate 11 and includes a plurality of pixel openings 15a. The isolation layer 12 is disposed on one side of the array substrate 11 and includes an isolation structure 12a and a plurality of isolation openings 12c formed by the isolation structure 12a. The plurality of isolation openings 12c are correspondingly connected to the plurality of pixel openings 15a, for example, in a one-to-one correspondence. The plurality of light-emitting portions 132 are disposed on one side of the array substrate 11 and are correspondingly arranged to the plurality of pixel openings 15a, for example, in a one-to-one correspondence. It is understood that the display panel 10 also includes a plurality of light-emitting elements 13, each light-emitting element 13 including a first electrode 131, a light-emitting portion 132, and a second electrode 133 stacked together.

[0151] At least one pixel opening 15a includes a plurality of sub-pixel openings 15a1 spaced apart, and the light-emitting portion 132 corresponding to the at least one pixel opening 15a includes a plurality of sub-portions 1321, which are arranged one-to-one with the plurality of sub-pixel openings 15a1, and are electrically connected to the same driving circuit in the array substrate 11. The isolation layer 12 also includes a partition wall 12b located between two adjacent sub-portions 1321, that is, the partition wall 12b divides the light-emitting portion 132 into a plurality of sub-portions 1321.

[0152] Further, refer to Figure 8 , Figure 12 and Figure 13 As shown, the distance between two adjacent sub-pixel openings 15a1 in the same pixel opening 15a is the first distance a, and the distance between the pixel opening 15a corresponding to the two adjacent sub-pixel openings 15a1 and the adjacent pixel opening 15a is the second distance b. The first distance a is greater than or less than the second distance b, that is, the first distance a and the second distance b are not equal.

[0153] The display panel 10 provided in this application embodiment divides the light-emitting part 132 into multiple sub-parts 1321 by a partition wall 12b. Thus, when one sub-part 1321 fails (such as due to particle residue, encapsulation failure, etc.), it will not affect the other sub-parts 1321, and the other sub-parts 1321 can still emit light normally, thereby reducing the risk of display defects in the display panel 10. Furthermore, by making the first spacing a and the second spacing b unequal, designers can adaptively adjust the opening size according to actual needs. For example, when the first spacing a is less than the second spacing b, it is equivalent to arranging the sub-parts 1321 of the light-emitting part 132 more compactly, which is conducive to maximizing the aperture ratio and minimizing the loss of aperture ratio caused by "separating the light-emitting part 132"; when the first spacing a is greater than the second spacing b, it is equivalent to arranging the sub-parts 1321 of the light-emitting part 132 more sparsely, which is conducive to setting via structures for connecting the anode and the driving circuit in the area between adjacent sub-pixel openings 15a1, thereby making it easier for designers to set the position of the via structure according to actual needs, and reducing the restriction on the setting position of the via structure caused by the arrangement position of the light-emitting part 132.

[0154] In one embodiment, the first spacing a is smaller than the second spacing b. In this way, the sub-segments 1321 of the light-emitting portion 132 can be arranged more compactly, while the light-emitting area of ​​the sub-segments 1321 can be set to be larger, which helps to maximize the aperture ratio and thus minimize the loss of aperture ratio caused by the "separation of light-emitting portion 132", ensuring the display effect.

[0155] Optionally, the difference between the first pitch a and the second pitch b is greater than 0 μm and less than or equal to 16 μm. For example, the difference between the first pitch a and the second pitch b can be 0.1 μm, 1 μm, 3 μm, 5 μm, 8 μm, 12 μm, 14 μm, 16 μm, or any two of the above values. By ensuring that the difference between the first pitch a and the second pitch b is within the above range, it is beneficial to improve the aperture ratio and ensure display quality.

[0156] Optionally, the first spacing 'a' is greater than 0 μm and less than or equal to 12 μm. For example, the first spacing 'a' can be 0.1 μm, 2 μm, 4 μm, 6 μm, 10 μm, 12 μm, or any two of the above values. By ensuring the first spacing 'a' is within the above range, it is beneficial to improve the aperture ratio and ensure display quality.

[0157] Optionally, the second spacing b is greater than or equal to 10 μm and less than or equal to 20 μm. For example, the second spacing b can be 10 μm, 13 μm, 14 μm, 16 μm, 18 μm, 20 μm, or any two of the above values. By ensuring that the difference in the second spacing b falls within the above range, it is beneficial to improve the aperture ratio and ensure display quality.

[0158] In one embodiment, the first spacing 'a' is greater than or less than the spacing between any two adjacent pixel openings 15a. When the first spacing is less than the spacing between any two adjacent pixel openings 15a, it is equivalent to arranging the sub-parts 1321 of the light-emitting part 132 more compactly, which is beneficial to maximizing the aperture ratio and minimizing the loss of aperture ratio caused by "separating the light-emitting part 132". When the first spacing is greater than the spacing between any two adjacent pixel openings 15a, it is equivalent to arranging the sub-parts 1321 of the light-emitting part 132 more sparsely, which is beneficial to setting via structures for connecting the anode and the driving circuit in the area between adjacent sub-pixel openings 15a1. This makes it easier for designers to set the position of the via structure according to actual needs and reduces the limitation on the setting position of the via structure caused by the arrangement position of the light-emitting part 132.

[0159] Optionally, the first spacing a is smaller than the spacing between any two adjacent pixel openings 15a. In this way, the sub-parts 1321 of the light-emitting part 132 can be arranged more compactly, and the light-emitting area of ​​the sub-parts 1321 can be set to be larger, which helps to maximize the aperture ratio and thus minimize the loss of aperture ratio caused by "separating the light-emitting part 132", ensuring the display effect.

[0160] Optionally, the difference between the first spacing a and the spacing between any two adjacent pixel openings 15a is greater than 0 μm and less than or equal to 16 μm. For example, this difference can be 0.1 μm, 1 μm, 3 μm, 5 μm, 8 μm, 12 μm, 14 μm, 16 μm, or between any two of the above values. By ensuring that the difference between the first spacing a and the spacing between any two adjacent pixel openings 15a is within the above range, it is beneficial to improve the aperture ratio and ensure display quality.

[0161] In one embodiment, the isolation opening 12c corresponding to the at least one pixel opening 15a includes a plurality of sub-isolation openings 12c1, which are connected one-to-one with the plurality of sub-pixel openings 15a1 of the pixel opening 15a; a partition wall 12b is provided between two adjacent sub-isolation openings 12c1, that is, the partition wall 12b divides the isolation opening 12c into a plurality of sub-isolation openings 12c1. In one example, the number of sub-isolation openings 12c1 is n, and the number of partition walls 12b is n-1.

[0162] By setting the partition wall 12b, the light-emitting part 132 can be divided into multiple sub-parts 1321, so that each sub-part 1321 remains independent and avoids the failure of one sub-part 1321 affecting other sub-parts 1321.

[0163] Optionally, refer to Figure 5As shown, the distance between two adjacent sub-isolation openings 12c1 within the same isolation opening 12c is the third distance c, and the distance between the isolation opening 12c corresponding to the two adjacent sub-isolation openings 12c1 and the adjacent isolation opening 12c is the fourth distance d. The third distance c is greater than or less than the fourth distance d. In one example, the third distance c is greater than the fourth distance d. In another example, the third distance c is less than the fourth distance d.

[0164] Here, the third spacing c can also be understood as the maximum spacing between the side of the partition wall 12b closest to one sub-isolation opening 12c1 and the side of the partition wall 12b closest to another sub-isolation opening 12c1. This configuration allows the isolation opening 12c to adapt to the arrangement of the pixel opening 15a, thereby helping the center of the sub-isolation opening 12c1 to coincide as closely as possible with the center of the sub-pixel opening 15a1, which in turn helps to maximize the effective light-emitting area of ​​the sub-part 1321 of the light-emitting part 132.

[0165] Optionally, the third spacing c is smaller than the spacing between any two adjacent isolation openings 12c. This setting allows the isolation openings 12c to be adapted to the pixel opening 15a's configuration, helping to maximize the aperture ratio.

[0166] In one embodiment, the orthographic projection of the isolation structure 12a onto the array substrate 11 is within the orthographic projection range of the pixel limiting layer 15 onto the array substrate 11.

[0167] Optionally, the orthographic projection of the pixel opening 15a onto the array substrate 11 lies within the orthographic projection of the isolation opening 12c onto the array substrate 11. Here, "the orthographic projection of the pixel opening 15a onto the array substrate 11" refers to the orthographic projection of the edge of the pixel opening 15a closest to the array substrate 11 onto the array substrate 11. "The orthographic projection of the isolation opening 12c onto the array substrate 11" refers to the orthographic projection of the wall surface at the smallest diameter of the isolation opening 12c onto the array substrate 11.

[0168] In one embodiment, such as Figure 9 As shown, the maximum distance between the orthographic projection outer contour of the sub-isolation opening 12c1 on the array substrate 11 and the orthographic projection outer contour of the corresponding sub-pixel opening 15a1 on the array substrate 11 is the first distance e. Here, "orthographic projection outer contour of the sub-isolation opening 12c1 on the array substrate 11" refers to the orthographic projection contour of the wall surface at the smallest diameter of the sub-isolation opening 12c1 on the array substrate 11. "Orthographic projection outer contour of the sub-pixel opening 15a1 on the array substrate 11" refers to the orthographic projection of the edge of the sub-pixel opening 15a1 on the side closer to the array substrate 11 on the array substrate 11.

[0169] Specifically, within the same isolation opening 12c, the first distance e corresponding to at least two sub-isolation openings 12c1 is equal. This helps to ensure that at least two sub-isolation openings 12c1 within the same isolation opening 12c are aligned with the corresponding sub-pixel openings 15a1 within the same pixel opening 15a, thereby improving the display uniformity of characters positioned slightly below the viewpoint.

[0170] Optionally, within the same isolation opening 12c, the first distance e corresponding to each sub-isolation opening 12c1 is equal. This helps to ensure that all sub-isolation openings 12c1 within the same isolation opening 12c are aligned with the corresponding sub-pixel openings 15a1 within the same pixel opening 15a, thereby improving the display uniformity of characters positioned slightly below the viewpoint.

[0171] In one embodiment, within the same isolation opening 12c, the first distance e corresponding to at least two sub-isolation openings 12c1 is not equal. This helps to reduce the alignment accuracy during the manufacturing process, thereby reducing the manufacturing difficulty.

[0172] Optionally, within the same isolation opening 12c, the first distance e corresponding to each sub-isolation opening 12c1 is not equal. This helps to reduce the alignment accuracy during the manufacturing process, thereby reducing the manufacturing difficulty.

[0173] In one embodiment, the display panel 10 further includes a plurality of second electrodes 133 corresponding one-to-one with the plurality of light-emitting portions 132. The second electrodes 133 are disposed on the side of the corresponding light-emitting portion 132 away from the array substrate 11; the second electrodes 133 are electrically connected to the isolation layer 12. It is understood that the isolation structure 12a can be electrically connected to the driving circuit of the display panel 10. In this embodiment, the second electrodes 133 of the light-emitting element 13 are connected to the driving circuit through the isolation structure 12a. In this way, the wiring arrangement in the display area of ​​the display panel 10 can be more optimized. Exemplarily, the second electrode 133 can be a cathode.

[0174] Optionally, refer to Figure 2 As shown, the second electrode 133 corresponding to the at least one pixel opening 15a includes a plurality of sub-electrode portions 1331. Each sub-electrode portion 1331 is electrically connected to the isolation layer 12. In this way, the sub-electrode portions 1331 corresponding to each sub-part 1321 are electrically connected to the isolation layer 12 respectively, avoiding damage to the sub-electrode portions 1331 on one sub-part 1321 from affecting the sub-electrode portions 1331 on other sub-parts 1321, thereby improving the light emission reliability of the display panel 10.

[0175] Optionally, at least a portion of the outer edge of the sub-electrode portion 1331 covers the sidewall of the isolation structure 12a near the sub-isolation opening 12c1, and / or, at least a portion of the outer edge of the sub-electrode portion 1331 covers the sidewall of the partition wall 12b near the sub-isolation opening 12c1. This allows the sub-electrode portion 1331 to have a larger contact area with the isolation structure 12a and / or the partition wall 12b, reducing electrical connection resistance.

[0176] It should be noted that if a second electrode 133 is a single structure and is not divided into multiple sub-electrode portions 1331, then at least a portion of the outer edge of the second electrode 133 covers the sidewall of the isolation structure 12a near the isolation opening 12c.

[0177] Optionally, in the same second electrode 133, the distance between the outer edge of each sub-electrode portion 1331 and the array substrate 11 is equal; in other words, the overlap height of each sub-electrode portion 1331 on the isolation layer 12 is consistent. It should be emphasized here that, due to manufacturing process limitations, "approximately equal" can also be considered as equal. This arrangement helps to maintain consistent electrical connection resistance between each sub-electrode portion 1331 and the isolation layer 12, thus improving light emission uniformity.

[0178] Optionally, both the isolation structure 12a and the partition wall 12b include a conductive portion 121 and a blocking portion 122 stacked along a direction away from the array substrate 11, with the orthographic projection of the conductive portion 121 on the array substrate 11 located within the orthographic projection range of the blocking portion 122 on the array substrate 11; the second electrode 133 is electrically connected to the conductive portion 121. It is understood that the sub-electrode portion 1331 is also electrically connected to the conductive portion 121.

[0179] In one embodiment, the conductive portion 121 includes at least one metal layer. In one example, the conductive portion 121 includes one metal layer. Further, the material of the conductive portion 121 includes at least one of a metal and a metal oxide. Exemplarily, the metal may be silver, copper, titanium, aluminum, etc. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, etc.

[0180] In one embodiment, the material of the blocking portion 122 includes titanium or molybdenum.

[0181] In one embodiment, the lower surface of the blocking portion 122 of the partition wall 12b has a third spacing c in the arrangement direction along the two adjacent sub-isolation openings 12c1. The lower surface of the blocking portion 122 of the isolation structure 12a has a fourth spacing d in the arrangement direction along the two adjacent isolation openings 12c.

[0182] In one embodiment, the plurality of light-emitting portions 132 includes a plurality of first light-emitting portions 132a, a plurality of second light-emitting portions 132b, and a plurality of third light-emitting portions 132c; the first light-emitting portions 132a, second light-emitting portions 132b, and third light-emitting portions 132c emit different colors. The plurality of pixel openings 15a includes a plurality of first pixel openings 15a-1, a plurality of second pixel openings 15a-2, and a plurality of third pixel openings 15a-3, with the first light-emitting portions 132a corresponding to the first pixel openings 15a-1, the second light-emitting portions 132b corresponding to the second pixel openings 15a-2, and the third light-emitting portions 132c corresponding to the third pixel openings 15a-3. The plurality of isolation openings 12c includes a plurality of first isolation openings 12c-1, a plurality of second isolation openings 12c-2, and a plurality of third isolation openings 12c-3. The first isolation opening 12c-1 is connected to the first pixel opening 15a-1, the second isolation opening 12c-2 is connected to the second pixel opening 15a-2, and the third isolation opening 12c-3 is connected to the third pixel opening 15a-3.

[0183] Specifically, the first pixel opening 15a-1 includes a plurality of first sub-pixel openings 15a1-1 spaced apart, and the first light-emitting part 132a includes a plurality of first sub-parts 1321a spaced apart. The first isolation opening 12c-1 includes a plurality of first sub-isolation openings 12c1-1.

[0184] In this way, it is equivalent to dividing the light-emitting part 132 of the same color into multiple first sub-parts 1321a, which helps to maintain the uniformity of the display. It can be understood that the first light-emitting part 132a can be one of the red light-emitting part 132, the blue light-emitting part 132, and the green light-emitting part 132.

[0185] Optionally, the display panel 10 further includes a plurality of first electrodes 131 corresponding to a plurality of light-emitting portions 132, wherein the first electrodes 131 are disposed between the corresponding light-emitting portion 132 and the array substrate 11. For example, the first electrode 131 may be an anode.

[0186] In one embodiment, reference Figure 2 and Figure 11 As shown, the display panel 10 also includes a plurality of first encapsulation portions 141, which are correspondingly disposed with a plurality of first light-emitting portions 132a. The first encapsulation portions 141 are disposed on the side of the corresponding first light-emitting portion 132a away from the array substrate 11. For example, the first encapsulation portion 141 may be an inorganic film layer.

[0187] Optionally, such as Figure 2As shown, the orthographic projection of the first encapsulation portion 141 on the array substrate 11 covers the orthographic projections of the plurality of first sub-parts 1321a corresponding to the first light-emitting portion 132a on the array substrate 11, as well as the orthographic projection of the partition wall 12b corresponding to the first light-emitting portion 132a on the array substrate 11. That is, the first encapsulation portion 141 has a continuous film layer structure. In this way, the contact area between the first encapsulation portion 141 and other film layers in the display panel 10 can be increased, thereby improving the connection stability of the first encapsulation portion 141 and enhancing the encapsulation reliability.

[0188] Optionally, a light-emitting material layer 161 and an electrode material layer 162 are further provided between the partition wall 12b between two adjacent first sub-parts 1321a and the first encapsulation part 141.

[0189] Optionally, such as Figure 4 As shown, the first encapsulation portion 141 includes a plurality of first sub-encapsulation portions 141a spaced apart. The plurality of first sub-encapsulation portions 141a are correspondingly arranged with a plurality of first sub-parts 1321a, and the first sub-encapsulation portion 141a is located on the side of the corresponding first sub-part 1321a away from the array substrate 11. In this way, it is equivalent to encapsulating each first sub-part 1321a individually. Thus, when the encapsulation of one first sub-encapsulation portion 141a fails, it will not affect the encapsulation performance of other first sub-encapsulation portions 141a, ensuring that the other first sub-parts 1321a can all emit light normally, reducing the risk of display defects in the display panel 10.

[0190] In one embodiment, such as Figure 6 As shown, the orthographic projection of the first electrode 131 corresponding to the first light-emitting part 132a on the array substrate 11 covers the orthographic projections of the plurality of first sub-parts 1321a corresponding to the first light-emitting part 132a on the array substrate 11 and the orthographic projection of the partition wall 12b corresponding to the first light-emitting part 132a on the array substrate 11. That is, the first electrode 131 corresponding to the first light-emitting part 132a is a complete block structure. This is beneficial for increasing the area of ​​the first electrode 131 and reducing the resistance of the first electrode 131.

[0191] Optionally, the first electrode 131 corresponding to the first light-emitting portion 132a includes a first main body portion 1311a, and the orthographic projection of each first sub-portion 1321a of the first light-emitting portion 132a onto the array substrate 11 is located within the orthographic projection range of the first main body portion 1311a onto the array substrate 11. For example, the shape of the first main body portion 1311a is a regular block structure.

[0192] Optionally, the first main body 1311a is electrically connected to the driving circuit in the array substrate 11 through a first via structure 11b. It is understood that the array substrate 11 is provided with multiple first driving circuits 11a, multiple second driving circuits (not shown), and multiple third driving circuits (not shown). The first electrode 131 of each first light-emitting element 13a is electrically connected to a corresponding first driving circuit 11a through the first via structure 11b. The first electrode 131 of each second light-emitting element 13b is electrically connected to a corresponding second driving circuit through a second via structure 11c. The first electrode 131 of each third light-emitting element 13c is electrically connected to a corresponding third driving circuit through a third via structure 11d.

[0193] Optionally, the first electrode 131 further includes a first protrusion 1312a connected to the first main body portion 1311a. The first protrusion 1312a is electrically connected to the first driving circuit 11a in the array substrate 11 through a first via structure 11b. In this way, the orthographic projection of the first via structure 11b on the array substrate 11 is outside the orthographic projection of the first light-emitting portion 132a on the array substrate 11, thus avoiding any adverse effect of the first via structure 11b on the light emission of the first light-emitting element 13a.

[0194] Optionally, the orthographic projection of the first protrusion 1312a on the array substrate 11 is located within the orthographic projection range of the isolation structure 12a on the array substrate 11.

[0195] In one embodiment, reference Figures 14-19 As shown, the first electrode 131 corresponding to the first light-emitting part 132a includes a plurality of first sub-electrodes 1313a and at least one first connecting line 1314a. The plurality of first sub-electrodes 1313a are correspondingly disposed with respect to the plurality of first sub-parts 1321a, and are located between the corresponding first sub-part 1321a and the array substrate 11. Two adjacent first sub-electrodes 1313a are connected by the first connecting line 1314a. Thus, when a short circuit defect occurs in one of the first sub-electrodes 1313a, the first connecting line 1314a can be burned off by a laser, thereby ensuring that the other first sub-electrodes 1313a can function normally, which helps to improve display defects caused by short circuits.

[0196] Optionally, the isolation structure 12a includes a first through-hole 12d corresponding to the first connecting line 1314a. The orthographic projection of the hole wall of the first through-hole 12d onto the array substrate 11 overlaps with the orthographic projection of the corresponding first connecting line 1314a onto the array substrate 11. Thus, during the repair process, a laser can irradiate the first connecting line 1314a through the first through-hole 12d, thereby burning off the first connecting line 1314a.

[0197] It should be noted that during the repair process, the laser can also irradiate the first connecting line 1314a from the back of the display panel 10, thereby burning off the first connecting line 1314a. Understandably, in this case, the metal film layer in the array substrate 11 should not overlap with the laser irradiation area of ​​the first connecting line 1314a to prevent blocking the laser.

[0198] Optionally, the first through-hole 12d can be reused as a light-transmitting hole. In this way, on the one hand, it helps to improve the light transmittance of the display panel 10, and on the other hand, the first through-hole 12d has multiple functions, which helps to reduce the number of openings on the isolation structure 12a.

[0199] Optionally, the first electrode 131 corresponding to the first light-emitting part 132a further includes a first protrusion 1312a connected to the first sub-electrode 1313a, and the first protrusion 1312a is electrically connected to the first driving circuit 11a in the array substrate 11 through the first via structure 11b.

[0200] Optionally, the orthographic projection of the first protrusion 1312a on the array substrate 11 is located within the orthographic projection range of the isolation structure 12a on the array substrate 11.

[0201] In one embodiment, such as Figure 14 As shown, the first protrusion 1312a is in contact with any one of the first sub-electrodes 1313a of the first electrode 131, that is, it is directly connected to any one of the first sub-electrodes 1313a.

[0202] Optionally, the plurality of first sub-electrodes 1313a are arranged at intervals along a preset direction, i.e., as follows: Figure 14 The vertical arrangement is sequential.

[0203] Optionally, in the same first electrode 131, all first sub-electrodes 1313a are located on one side of the first protrusion 1312a along a predetermined direction; the first protrusion 1312a is in contact with the adjacent first sub-electrode 1313a. For example... Figure 14 As shown in the orientation, all the first sub-electrodes 1313a are located on one side above the first protrusion 1312a, and the first protrusion 1312a is in contact with the nearest first sub-electrode 1313a to achieve electrical connection.

[0204] refer to Figure 14 , Figure 16 and Figure 17As shown, the four first sub-electrodes 1313a are arranged sequentially from top to bottom. When the first first sub-electrode 1313a is short-circuited, a laser is used to burn off the first connecting line 1314a between the first and second first sub-electrodes 1313a, while the remaining three first sub-electrodes 1313a can still function normally. When the second first sub-electrode 1313a is short-circuited, a laser is used to burn off the first connecting line 1314a between the second and third first sub-electrodes 1313a, while the remaining two first sub-electrodes 1313a can still function normally. When the third first sub-electrode 1313a is short-circuited, a laser is used to burn off the first connecting line 1314a between the third and fourth first sub-electrodes 1313a, while the fourth first sub-electrode 1313a can still function normally.

[0205] In one embodiment, such as Figure 18 As shown, the first protrusion 1312a is located between two adjacent first sub-electrodes 1313a. The first protrusion 1312a can be connected to either of the two first sub-electrodes 1313a.

[0206] Optionally, in the same first electrode 131, all first sub-electrodes 1313a are located on both sides of the first protrusion 1312a along a preset direction; a first sub-electrode 1313a adjacent to the first protrusion 1312a is in contact with the first protrusion 1312a.

[0207] Optionally, the number of first sub-electrodes 1313a located on one side of the first protrusion 1312a along a preset direction is equal to the number of first sub-electrodes 1313a located on the other side of the first protrusion 1312a along the preset direction.

[0208] Reference Figure 18 and Figure 19 As shown, the four first sub-electrodes 1313a are arranged sequentially from top to bottom. When the first first sub-electrode 1313a is short-circuited, a laser is used to burn off the first connecting line 1314a between the first and second first sub-electrodes 1313a, while the remaining three first sub-electrodes 1313a can still function normally. When the third first sub-electrode 1313a is short-circuited, a laser is used to burn off the first connecting line 1314a between the third and second first sub-electrodes 1313a, while the remaining two first sub-electrodes 1313a can still function normally. When the fourth first sub-electrode 1313a is short-circuited, a laser is used to burn off the first connecting line 1314a between the third and fourth first sub-electrodes 1313a, while the remaining three first sub-electrodes 1313a can still function normally.

[0209] It is understood that the first electrode 131 corresponding to the first light-emitting part 132a may include a plurality of first protrusions 1312a. The embodiments of this application do not impose any particular limitation on the number and arrangement position of the first protrusions 1312a.

[0210] In one embodiment, the second pixel opening 15a-2 includes a plurality of second sub-pixel openings 15a1-2 spaced apart, and the second light-emitting portion 132b includes a plurality of second sub-portions 1321b spaced apart. The second isolation opening 12c-2 includes a plurality of second sub-isolation openings 12c1-2.

[0211] In this way, it is equivalent to dividing the light-emitting part 132 of the same color into multiple second sub-parts 1321b, which helps to maintain display uniformity. It can be understood that the second light-emitting part 132b can be one of the red light-emitting part 132, the blue light-emitting part 132, and the green light-emitting part 132.

[0212] Optionally, the display panel 10 further includes a plurality of second encapsulation portions 142, which are correspondingly disposed with respect to a plurality of second light-emitting portions 132b. The second encapsulation portions 142 are located on the side of the corresponding second light-emitting portion 132b away from the array substrate 11. For example, the second encapsulation portion 142 may be an inorganic film layer.

[0213] Optionally, the orthographic projection of the second encapsulation portion 142 on the array substrate 11 covers the orthographic projections of the plurality of second sub-parts 1321b corresponding to the second light-emitting portion 132b on the array substrate 11 and the orthographic projection of the partition wall 12b corresponding to the second light-emitting portion 132b on the array substrate 11. That is, the second encapsulation portion 142 has a continuous film layer structure. In this way, the contact area between the second encapsulation portion 142 and other film layers in the display panel 10 can be increased, improving the connection stability of the second encapsulation portion 142 and enhancing the encapsulation reliability.

[0214] Optionally, a light-emitting material layer 161 and an electrode material layer 162 are further provided between the partition wall 12b between two adjacent second sub-parts 1321b and the second encapsulation part 142.

[0215] Optionally, the second encapsulation portion 142 includes a plurality of second sub-encapsulation portions (not shown) spaced apart. These plurality of second sub-encapsulation portions correspond to the plurality of second sub-parts 1321b, with each second sub-encapsulation portion located on the side of the corresponding second sub-part 1321b away from the array substrate 11. This is equivalent to individually encapsulating each second sub-part 1321b. Therefore, if one second sub-encapsulation portion fails, it will not affect the encapsulation performance of the other second sub-encapsulation portions, ensuring that all other second sub-parts 1321b can emit light normally, thus reducing the risk of display defects in the display panel 10.

[0216] In one embodiment, the orthographic projection of the first electrode 131 corresponding to the second light-emitting portion 132b onto the array substrate 11 covers the orthographic projections of the plurality of second sub-parts 1321b corresponding to the second light-emitting portion 132b onto the array substrate 11 and the orthographic projection of the partition wall 12b corresponding to the second light-emitting portion 132b onto the array substrate 11. That is, the first electrode 131 corresponding to the second light-emitting portion 132b is a complete block structure. This is beneficial for increasing the area of ​​the first electrode 131 and reducing the resistance of the first electrode 131.

[0217] Optionally, the first electrode 131 corresponding to the second light-emitting portion 132b includes a second main body portion 1311b, and the orthographic projection of each second sub-portion 1321b of the second light-emitting portion 132b onto the array substrate 11 is located within the orthographic projection range of the second main body portion 1311b onto the array substrate 11. Exemplarily, the shape of the second main body portion 1311b is a regular block structure.

[0218] Optionally, the second main body 1311b is electrically connected to the second driving circuit of the array substrate 11 through the second via structure 11c.

[0219] Optionally, the first electrode 131 corresponding to the second light-emitting portion 132b further includes a second protrusion 1312b connected to the second main body portion 1311b. The second protrusion 1312b is electrically connected to the second driving circuit of the array substrate 11 through a second via structure 11c. In this way, the orthographic projection of the second via structure 11c on the array substrate 11 is outside the orthographic projection of the second light-emitting portion 132b on the array substrate 11, thus avoiding any adverse effect of the second via structure 11c on the light emission of the second light-emitting element 13b.

[0220] Optionally, the orthographic projection of the second protrusion 1312b on the array substrate 11 is located within the orthographic projection range of the isolation structure 12a on the array substrate 11.

[0221] In one embodiment, reference Figures 14-19 As shown, the first electrode 131 corresponding to the second light-emitting part 132b includes a plurality of second sub-electrodes 1313b and at least one second connecting line 1314b. The plurality of second sub-electrodes 1313b are correspondingly disposed with respect to the plurality of second sub-parts 1321b, and are located between the corresponding second sub-part 1321b and the array substrate 11. Two adjacent second sub-electrodes 1313b are connected by the second connecting line 1314b. Thus, when a short-circuit defect occurs in one of the second sub-electrodes 1313b, the first connecting line 1314a can be burned off by a laser, thereby ensuring that the other second sub-electrodes 1313b can function normally, which helps to improve display defects caused by short circuits.

[0222] Optionally, the isolation structure 12a includes a second through-hole 12e corresponding to the second connecting line 1314b, wherein the orthographic projection of the hole wall of the second through-hole 12e on the array substrate 11 overlaps with the orthographic projection of the corresponding second connecting line 1314b on the array substrate 11. Thus, during the repair process, a laser can irradiate the second connecting line 1314b through the second through-hole 12e, thereby burning off the second connecting line 1314b.

[0223] It should be noted that during the repair process, the laser can also be used to irradiate the second connecting line 1314b from the back of the display panel 10, thereby burning off the second connecting line 1314b. Understandably, in this case, the metal film layer in the array substrate 11 should not overlap with the laser irradiation area of ​​the second connecting line 1314b to prevent blocking the laser.

[0224] Optionally, the second through-hole 12e can be reused as a light-transmitting hole. In this way, on the one hand, it helps to improve the light transmittance of the display panel 10, and on the other hand, the second through-hole 12e has multiple functions, which helps to reduce the number of openings on the isolation structure 12a.

[0225] Optionally, the first electrode 131 corresponding to the second light-emitting part 132b further includes a second protrusion 1312b connected to the second sub-electrode 1313b, and the second protrusion 1312b is electrically connected to the second driving circuit of the array substrate 11 through the second via structure 11c.

For example... Figure 14 As shown in the orientation, all the second sub-electrodes 1313b are located on the side above the second protrusion 1312b, and the second protrusion 1312b is in contact with the nearest second sub-electrode 1313b to achieve electrical connection.

[0231] Optionally, in the same first electrode 131, all second sub-electrodes 1313b are located on both sides of the second protrusion 1312b along a preset direction; a second sub-electrode 1313b adjacent to the second protrusion 1312b is in contact with the second protrusion 1312b.

[0232] Optionally, the number of second sub-electrodes 1313b located on one side of the second protrusion 1312b along a preset direction is equal to the number of second sub-electrodes 1313b located on the other side of the second protrusion 1312b along the preset direction.

[0233] It is understood that the repair method of the second light-emitting element 13b is the same as that of the first light-emitting element 13a, and will not be described again in the embodiments of this application.

[0234] It is understood that the first electrode 131 corresponding to the second light-emitting part 132b may include a plurality of second protrusions 1312b. The embodiments of this application do not impose any particular limitation on the number and arrangement position of the second protrusions 1312b.

The third isolation opening 12c-3 includes a plurality of third sub-isolation openings 12c1-3.

[0236] In this way, it is equivalent to dividing the light-emitting part 132 of the same color into multiple third sub-parts 1321c, which helps to maintain display uniformity. It can be understood that the third light-emitting part 132c can be one of the red light-emitting part 132, the blue light-emitting part 132, and the green light-emitting part 132.

[0237] Optionally, refer to Figure 2 and Figure 11 As shown, the display panel 10 also includes a plurality of third encapsulation portions 143, which are correspondingly disposed with a plurality of third light-emitting portions 132c. The third encapsulation portions 143 are disposed on the side of the corresponding third light-emitting portion 132c away from the array substrate 11. For example, the third encapsulation portion 143 may be an inorganic film layer.

[0238] Optionally, such as Figure 2As shown, the orthographic projection of the third encapsulation portion 143 on the array substrate 11 covers the orthographic projections of the plurality of third sub-parts 1321c corresponding to the third light-emitting portion 132c on the array substrate 11, as well as the orthographic projection of the partition wall 12b corresponding to the third light-emitting portion 132c on the array substrate 11. That is, the third encapsulation portion 143 has a continuous film layer structure. In this way, the contact area between the third encapsulation portion 143 and other film layers in the display panel 10 can be increased, thereby improving the connection stability of the third encapsulation portion 143 and enhancing the encapsulation reliability.

[0239] Optionally, a light-emitting material layer 161 and an electrode material layer 162 are further provided between the partition wall 12b between two adjacent third sub-parts 1321c and the third encapsulation part 143.

[0240] Optionally, such as Figure 4 As shown, the third encapsulation section 143 includes a plurality of third sub-encapsulation sections (not shown) spaced apart. The plurality of third sub-encapsulation sections are correspondingly arranged with a plurality of third sub-sections 1321c, and the third sub-encapsulation sections are located on the side of the corresponding third sub-section 1321c away from the array substrate 11. This is equivalent to individually encapsulating each third sub-section 1321c. Therefore, if one third sub-encapsulation section fails, it will not affect the encapsulation performance of the other third sub-encapsulation sections, ensuring that the other third sub-sections 1321c can all emit light normally, reducing the risk of display defects in the display panel 10.

[0241] In one embodiment, the orthographic projection of the first electrode 131 corresponding to the third light-emitting portion 132c onto the array substrate 11 covers the orthographic projections of the plurality of third sub-parts 1321c corresponding to the third light-emitting portion 132c onto the array substrate 11 and the orthographic projection of the partition wall 12b corresponding to the third light-emitting portion 132c onto the array substrate 11. That is, the first electrode 131 corresponding to the third light-emitting portion 132c is a complete block structure. This is beneficial for increasing the area of ​​the first electrode 131 and reducing the resistance of the first electrode 131.

[0242] Optionally, the first electrode 131 corresponding to the third light-emitting portion 132c includes a third main body portion 1311c, and the orthographic projection of each third sub-portion 1321c of the third light-emitting portion 132c onto the array substrate 11 is located within the orthographic projection range of the third main body portion 1311c onto the array substrate 11. Exemplarily, the shape of the third main body portion 1311c is a regular block structure.

[0244] Optionally, the first electrode 131 corresponding to the third light-emitting portion 132c further includes a third protrusion 1312c connected to the third main body portion 1311c. The third protrusion 1312c is electrically connected to the third driving circuit of the array substrate 11 through a third via structure 11d. In this way, the orthographic projection of the third via structure 11d on the array substrate 11 is outside the orthographic projection of the third light-emitting portion 132c on the array substrate 11, thus avoiding any adverse effect of the third via structure 11d on the light emission of the third light-emitting element 13c.

The plurality of third sub-electrodes 1313c are correspondingly disposed with respect to the plurality of third sub-parts 1321c, and are located between the corresponding third sub-part 1321c and the array substrate 11. Two adjacent third sub-electrodes 1313c are connected by the third connecting line 1314c. Thus, when a short-circuit defect occurs in one of the third sub-electrodes 1313c, the first connecting line 1314c can be burned off by a laser, thereby ensuring that the other third sub-electrodes 1313c can function normally, which helps to improve display defects caused by short circuits.

[0247] Optionally, the isolation structure 12a includes a third through-hole 12f corresponding to the third connecting line 1314c. The orthographic projection of the hole wall of the third through-hole 12f onto the array substrate 11 overlaps with the orthographic projection of the corresponding third connecting line 1314c onto the array substrate 11. Thus, during the repair process, a laser can irradiate the third connecting line 1314c through the third through-hole 12f, thereby burning off the third connecting line 1314c.

[0248] It should be noted that during the repair process, the laser can also irradiate the third connecting line 1314c from the back of the display panel 10, thereby burning off the third connecting line 1314c. Understandably, in this case, the metal film layer in the array substrate 11 should not overlap with the laser irradiation area of ​​the third connecting line 1314c to prevent blocking the laser.

[0249] Optionally, the third through-hole 12f can be reused as a light-transmitting hole. In this way, on the one hand, it helps to improve the light transmittance of the display panel 10, and on the other hand, the third through-hole 12f has multiple functions, which helps to reduce the number of openings on the isolation structure 12a.

[0258] It is understood that the repair method of the third light-emitting element 13c is the same as that of the first light-emitting element 13a, and will not be described again in the embodiments of this application.

[0259] It is understood that the first electrode 131 corresponding to the third light-emitting part 132c may include a plurality of third protrusions 1312c.

The light-emitting part 132 corresponding to the at least one pixel opening 15a includes n sub-parts 1321, where n is less than m. The n sub-parts 1321 and the n sub-pixel openings 15a1 are all arranged in a one-to-one correspondence with the n sub-isolation openings 12c1, and the remaining sub-isolation openings 12c1 are reused as light-transmitting holes. That is, the light-emitting material and the second electrode 133 in some sub-isolation openings 12c1 within the same isolation opening 12c are removed, so that some sub-isolation openings 12c1 are reused as light-transmitting holes. In this way, on the one hand, it helps to improve the light transmittance of the display panel 10, which is convenient for setting up under-screen optical devices, and on the other hand, it helps to reduce the number of openings on the isolation structure 12a.

The isolation layer 12 is disposed on one side of the array substrate 11 and includes an isolation structure 12a and an isolation structure 12a including a plurality of isolation openings 12c. The plurality of light-emitting portions 132 are disposed on one side of the array substrate 11 and are correspondingly disposed to the plurality of isolation openings 12c.

[0264] At least one isolation opening 12c includes a plurality of spaced-apart sub-isolation openings 12c1, and the light-emitting portion 132 corresponding to at least one isolation opening 12c includes a plurality of sub-portions 1321, which are arranged one-to-one with the plurality of sub-isolation openings 12c1, and are electrically connected to the same driving circuit in the array substrate 11; the isolation layer 12 also includes a partition wall 12b located between two adjacent sub-portions 1321. It is understood that the display panel 10 also includes a plurality of light-emitting elements 13, each light-emitting element 13 including a first electrode 131, a light-emitting portion 132 and a second electrode 133 stacked together.

[0265] Furthermore, the distance between the light-emitting areas of two adjacent sub-parts 1321 in the same light-emitting part 132 is the first distance a, and the distance between the light-emitting areas of the light-emitting parts 132 corresponding to the two adjacent sub-parts 1321 and the light-emitting areas of the adjacent light-emitting parts 132 is the second distance b, and the first distance a is greater than or less than the second distance b.

[0266] Here, the light-emitting area of ​​the light-emitting part 132 refers to the contact area between the first electrode 131 and the light-emitting part 132. In one example, the light-emitting area of ​​the light-emitting part 132 can be defined by the pixel opening 15a of the pixel defining layer 15.

[0267] The display panel 10 provided in this application embodiment includes at least one isolation opening 12c comprising multiple sub-isolation openings 12c1, and the light-emitting part 132 corresponding to the isolation opening 12c comprising multiple sub-parts 1321, wherein the multiple sub-parts 1321 are electrically connected to the same driving circuit; a partition wall 12b is provided between two adjacent sub-parts 1321, which is equivalent to dividing the light-emitting part 132 into multiple sub-parts 1321 through the partition wall 12b. In this way, when one sub-part 1321 fails, it will not affect the other sub-parts 1321, and the other sub-parts 1321 can still emit light normally, thereby reducing the risk of display failure of the display panel 10. Furthermore, by making the first spacing a and the second spacing b unequal, it is beneficial for designers to adaptively adjust the setting position of the light-emitting part 132 according to actual needs. For example, when the first spacing a is smaller than the second spacing b, it is beneficial to maximize the aperture ratio and minimize the loss of aperture ratio caused by the "separating light-emitting part 132"; when the first spacing a is larger than the second spacing b, it is beneficial to set a via structure for connecting the anode and the driving circuit in the area between adjacent sub-parts 1321, so that the designer can set the position of the via structure according to actual needs, and reduce the restriction on the setting position of the via structure caused by the arrangement position of the light-emitting part 132.

[0268] This application provides a display device, including the display panel in any of the foregoing embodiments.
