[0002] This application claims priority to Chinese Patent Application No. 202411847052.2, filed on December 13, 2024, entitled “Display Panel and Display Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of displays, specifically to a display panel and a display device. Background Technology

[0004] Organic light-emitting diodes (OLEDs) and flat panel displays based on light-emitting diodes (LEDs) are widely used in various consumer electronics products such as mobile phones, televisions, laptops, and desktop computers due to their advantages such as high image quality, energy saving, thin body, and wide range of applications, becoming the mainstream of display devices.

[0005] 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.

Detailed Implementation

[0034] The present application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be understood that when describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean that it is directly above the other layer or region, or that it contains other layers or regions between it and the other layer or region. Furthermore, if the component is flipped over, that layer or region will be located "below" or "under" the other layer or region.

[0036] This application provides a display panel and a display device. The embodiments of the display panel and the display device will be described below with reference to the accompanying drawings.

[0037] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0038] Please refer to Figures 1 to 3 together. Figure 1 is a partial top view of a display panel provided in an embodiment of this application; Figure 2 is a partial cross-sectional view of a display panel provided in an embodiment of this application; and Figure 3 is a partial top view of a display panel in another embodiment.

[0039] As shown in Figures 1 to 3, a first aspect of this application provides a display panel 10, which includes: a substrate 100; an isolation layer 200 located on one side of the substrate 100, including an isolation structure 201 and an isolation opening 240 formed by the isolation structure 201; and a light-emitting layer 300 located on one side of the substrate 100, the light-emitting layer 300 including light-emitting units 310 at least partially located in the isolation opening 240, a plurality of light-emitting units 310 arranged along intersecting first direction X and second direction Y, and the light-emitting unit 310 including a first light-emitting unit 311 and a second light-emitting unit 311 adjacent to the first light-emitting unit 311 in the second direction Y. The first light-emitting unit 311, the third light-emitting unit 313, and the fourth light-emitting unit 314 adjacent to the first light-emitting unit 311 in the first direction X; the width of the isolation structure 201 between the first light-emitting unit 311 and the second light-emitting unit 312 is the first sub-width D1; the width of the isolation structure 201 between the first light-emitting unit 311 and the third light-emitting unit 313 is the second sub-width D2; and the width of the isolation structure 201 between the first light-emitting unit 311 and the fourth light-emitting unit 314 is the third sub-width D3. The sum of the first sub-width D1 and the second sub-width D2 is less than the third sub-width D3. The first direction X and the second direction Y intersect.

[0040] The width of the isolation structure 201 refers to the maximum size of the isolation structure 201 in the direction from one of the two isolation openings 240 on both sides of the isolation structure 201 to the adjacent other isolation opening 240.

[0041] According to an embodiment of this application, the display panel 10 includes a substrate 100, an isolation layer 200, and a light-emitting layer 300. The isolation structure 201 of the isolation layer 200 forms an isolation opening 240, and at least a portion of the light-emitting units 310 of the light-emitting layer 300 is located in the isolation opening 240, which can improve the problem of easy crosstalk between adjacent light-emitting units 310. Multiple light-emitting units 310 are arranged along intersecting first direction X and second direction Y. Each light-emitting unit 310 includes a first light-emitting unit 311, a second light-emitting unit 312 and a third light-emitting unit 313 adjacent to the first light-emitting unit 311 in the second direction Y, and a fourth light-emitting unit 314 adjacent to the first light-emitting unit 311 in the first direction X. The width of the isolation structure 201 between the first light-emitting unit 311 and the second light-emitting unit 312 is a first sub-width D1, the width of the isolation structure 201 between the first light-emitting unit 311 and the third light-emitting unit 313 is a second sub-width D2, and the width of the isolation structure 201 between the first light-emitting unit 311 and the fourth light-emitting unit 314 is a third sub-width D3. That is, the width of the isolation structure 201 between the first light-emitting unit 311 and the fourth light-emitting unit 314 adjacent in the first direction X is larger, which reduces the resistance of the isolation structure 201 extending in the second direction Y and reduces the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10 and improving the performance of the OLED display product.

[0042] As shown in Figure 2, in some optional embodiments, the display panel 10 further includes a pixel definition layer 500 located on one side of the substrate 100. The pixel definition layer 500 includes a pixel defining portion 510 and a pixel opening 520 formed by the pixel defining portion 510. At least a portion of the pixel opening 520 and the isolation opening 240 correspond one-to-one and are interconnected. For the display area of ​​the display panel 10, the pixel opening 520 and the isolation opening 240 correspond one-to-one and are interconnected.

[0043] In these optional embodiments, the pixel defining portion 510 of the pixel defining layer 500 encloses a pixel opening 520 to provide a light-emitting unit 310, thereby enabling the light-emitting unit 310 to emit light normally. Furthermore, the pixel defining portion 510 defines the light-emitting area of ​​each light-emitting unit 310, reducing color mixing issues between the light-emitting units 310.

[0044] In some alternative embodiments, the second light-emitting unit 312 and the third light-emitting unit 313 are located on both sides of the first light-emitting unit 311.

[0045] In these optional embodiments, when the second light-emitting unit 312 and the third light-emitting unit 313 are located on different sides of the first light-emitting unit 311, the sum of the first sub-width D1 and the second sub-width D2 is less than the third sub-width D3. That is, the width of the isolation structure 201 between the first light-emitting unit 311 and the fourth light-emitting unit 314 adjacent in the first direction X is larger, which reduces the resistance of the isolation structure 201 extending in the second direction Y and reduces the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0046] Please refer to Figure 4, which is a partial top view of the display panel in another embodiment.

[0047] As shown in Figure 4, in some optional embodiments, the light-emitting unit 310 further includes a fifth light-emitting unit 315 located in the same row as the first light-emitting unit 311, the second light-emitting unit 312 and the third light-emitting unit 313 along the second direction Y. The width of the isolation structure 201 located between the fifth light-emitting unit 315 and the third light-emitting unit 313 is a fourth sub-width D4, the sum of the fourth sub-width D4 and the first sub-width D1, or at least one of the fourth sub-width D4 and the sum of the second sub-width D2 is less than the third sub-width D3.

[0048] In these optional embodiments, the sum of the fourth sub-width D4 and the second sub-width D2 is less than the third sub-width D3; or, the sum of the fourth sub-width D4 and the first sub-width D1 is less than the third sub-width D3, and the sum of the fourth sub-width D4 and the second sub-width D2 is less than the third sub-width D3, such that the width of the isolation structure 201 between the adjacent first light-emitting unit 311 and the fourth light-emitting unit 314 in the first direction X is larger, such that the resistance of the isolation structure 201 extending in the second direction Y is reduced, the voltage drop of the isolation structure 201 is reduced, thereby reducing the overall power consumption of the display panel 10.

[0049] Optionally, the third sub-width D3 is greater than at least one of the first sub-width D1, the second sub-width D2, or the fourth sub-width D4, that is, the width of the isolation structure 201 between the first light-emitting unit 311 and the fourth light-emitting unit 314 adjacent in the first direction X is larger, so that the resistance of the isolation structure 201 extending in the second direction Y is reduced, the voltage drop of the isolation structure 201 is reduced, thereby reducing the overall power consumption of the display panel 10.

[0050] In some alternative embodiments, the third sub-width D3 is less than the sum of the first sub-width D1, the second sub-width D2, and the third sub-width D3.

[0051] In these optional embodiments, the third sub-width D3 is smaller than the sum of the first sub-width D1, the second sub-width D2, and the third sub-width D3. This avoids the problem that if the third sub-width D3 is too large, the area of ​​the isolation openings 240 on both sides of the isolation structure 201 with the excessive width will be too small, the aperture ratio of the light-emitting unit 310 will be reduced, and the display effect of the display panel 10 will be reduced. In other words, the impact of the excessively large third sub-width D3 on the aperture ratio is balanced.

[0052] Optionally, the second light-emitting unit 312 and the fifth light-emitting unit 315 emit the same color, that is, multiple first light-emitting units 311, multiple second light-emitting units 312 and multiple third light-emitting units 313 are arranged alternately in the second direction Y.

[0053] Please refer to Figure 5, which is a partial top view of the display panel in another embodiment.

[0054] As shown in Figure 5, in some optional embodiments, a plurality of first light-emitting units 311 and a plurality of fourth light-emitting units 314 are arranged along the first direction X to form a first pixel column 320, a plurality of second light-emitting units 312 are arranged along the first direction X to form a second pixel column 330, a plurality of third light-emitting units 313 are arranged along the first direction X to form a third pixel column 340, and the first pixel column 320, the second pixel column 330 and the third pixel column 340 are arranged alternately along the second direction Y.

[0055] In these optional embodiments, the width of the isolation structure 201 between adjacent first light-emitting units 311 and fourth light-emitting units 314 in the first pixel column 320 is a third sub-width D3. In adjacent first pixel columns 320 and second pixel columns 330, the width of the isolation structure 201 between the first light-emitting unit 311 of the first pixel column 320 and the second light-emitting unit 312 of the second pixel column 330 is a first sub-width D1. In adjacent first pixel columns 320 and third pixel columns 340, the width of the isolation structure 201 between the first light-emitting unit 311 of the first pixel column 320 and the third light-emitting unit 313 of the third pixel column 340 is a second sub-width D2. The sum of the first sub-width D1 and the second sub-width D2 is less than the third sub-width D3, which reduces the resistance of the isolation structure 201 located between the first light-emitting unit 311 and the fourth light-emitting unit 314 and extending in the second direction Y, and reduces the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0056] Optionally, the first light-emitting unit 311, the second light-emitting unit 312, and the third light-emitting unit 313 emit different colors. For example, the first light-emitting unit 311 emits red, the second light-emitting unit 312 emits green, and the third light-emitting unit 313 emits blue. In other embodiments, the first light-emitting unit 311 may also emit blue or green, the second light-emitting unit 312 may also emit red or blue, and the third light-emitting unit 313 may also emit red or green.

[0057] Optionally, the first light-emitting unit 311 and the fourth light-emitting unit 314 emit the same color, that is, multiple first light-emitting units 311 of the same color are arranged in the first direction X to form a first pixel column 320. The width of the isolation structure 201 between adjacent first light-emitting units 311 is the third sub-width D3. The resistance of the isolation structure 201 located between adjacent first light-emitting units 311 and extending in the second direction Y is reduced, and the voltage drop of the isolation structure 201 is reduced, thereby reducing the overall power consumption of the display panel 10.

[0058] Furthermore, when the first light-emitting unit 311 and the fourth light-emitting unit 314 have the same color, and the second light-emitting unit 312 and the fifth light-emitting unit 315 have the same color, multiple first light-emitting units 311 of the same color are arranged in the first direction X to form a first pixel column 320, multiple second light-emitting units 312 of the same color are arranged in the first direction X to form a second pixel column 330, and multiple third light-emitting units 313 of the same color are arranged in the first direction X to form a third pixel column 340. The first pixel column 320, the second pixel column 330, and the third pixel column 340 are arranged alternately in the second direction Y. This pixel arrangement structure is simple and easy to fabricate.

[0059] Please refer to Figure 6, which is a partial top view of the display panel in another embodiment.

[0060] As shown in Figure 6, in some optional embodiments, the width of the isolation structure 201 located between two adjacent second light-emitting units 312 is the fifth sub-width D5, and the third sub-width D3 is equal to the fifth sub-width D5.

[0061] In these optional embodiments, the third sub-width D3 is equal to the fifth sub-width D5, that is, the width of the isolation structure 201 located between adjacent first light-emitting units 311 and fourth light-emitting units 314 is equal to the width of the isolation structure 201 located between two adjacent second light-emitting units 312. This increases the width of the isolation structure 201 located between two adjacent second light-emitting units 312, thereby reducing the resistance of the isolation structure 201 located between two adjacent second light-emitting units 312 and extending in the second direction Y, and reducing the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0062] In some optional embodiments, the width of the isolation structure 201 located between two adjacent third light-emitting units 313 is the sixth sub-width D6, and the third sub-width D3 is equal to the sixth sub-width D6.

[0063] In these optional embodiments, the third sub-width D3 is equal to the sixth sub-width D6, that is, the width of the isolation structure 201 located between adjacent first light-emitting units 311 and fourth light-emitting units 314 is equal to the width of the isolation structure 201 located between two adjacent third light-emitting units 313. This increases the width of the isolation structure 201 located between two adjacent third light-emitting units 313, thereby reducing the resistance of the isolation structure 201 located between two adjacent third light-emitting units 313 and extending in the second direction Y, and reducing the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0064] Optionally, the third sub-width D3, the fifth sub-width D5, and the sixth sub-width D6 are all equal, making the arrangement of each light-emitting unit 310 more uniform, improving the display effect of the display panel 10, further reducing the overall resistance of the isolation structure 201, and thus reducing the overall power consumption of the display panel 10.

[0065] In some optional embodiments, the projected area of ​​the third light-emitting unit 313 on the substrate 100 is greater than or equal to the projected area of ​​the first light-emitting unit 311 on the substrate 100, and / or the projected area of ​​the third light-emitting unit 313 on the substrate 100 is greater than or equal to the projected area of ​​the second light-emitting unit 312 on the substrate 100.

[0066] The projected area of ​​the third light-emitting unit 313 on the substrate 100 is greater than or equal to the projected area of ​​the first light-emitting unit 311 on the substrate 100; or, the projected area of ​​the third light-emitting unit 313 on the substrate 100 is greater than or equal to the projected area of ​​the second light-emitting unit 312 on the substrate 100; or, the projected area of ​​the third light-emitting unit 313 on the substrate 100 is greater than or equal to the projected area of ​​the first light-emitting unit 311 on the substrate 100, and the projected area of ​​the third light-emitting unit 313 on the substrate 100 is greater than or equal to the projected area of ​​the second light-emitting unit 312 on the substrate 100.

[0067] In these optional embodiments, the color of the third light-emitting unit 313 can be blue, and the area of ​​the third light-emitting unit 313 can be set to be large, which can improve the service life of the third light-emitting unit 313 and avoid the problem that the display effect of the display panel 10 will decrease due to the excessively fast brightness decay rate of the third light-emitting unit 313.

[0068] Please refer to Figure 7, which is a partial top view of the display panel in another embodiment.

[0069] As shown in Figure 7, in some optional embodiments, the isolation opening 240 includes a first isolation opening 241, a second isolation opening 242, and a third isolation opening 243. At least a portion of the first light-emitting unit 311 is located within the first isolation opening 241, at least a portion of the second light-emitting unit 312 is located within the second isolation opening 242, and at least a portion of the third light-emitting unit 313 is located within the third isolation opening 243. The orthographic projections of adjacent first isolation openings 241, second isolation openings 242, and third isolation openings 243 onto the substrate 100 are located within the same virtual quadrilateral 250. The location of the virtual quadrilateral 250 is indicated by a dashed line in Figure 7. The dashed line does not constitute a limitation on the structure of the display panel 10 in this embodiment.

[0070] In these optional embodiments, adjacent first isolation openings 241, second isolation openings 242, and third isolation openings 243 are disposed within the same virtual quadrilateral 250. Multiple virtual quadrilaterals 250 are repeatedly arranged to form an entire surface of isolation openings 240, improving the uniformity of the distribution of the isolation openings 240 and thus improving the display effect of the display panel 10. The first isolation opening 241, second isolation opening 242, and third isolation opening 243 are disposed within a virtual quadrilateral 250, making their distribution more regular and easier to manufacture.

[0071] In some alternative embodiments, the isolation opening 240 has a first side 240a and a second side 240b disposed opposite each other in a first direction X, and the first side 240a and the second side 240b of each of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243 coincide with the side of the virtual quadrilateral 250.

[0072] In these optional embodiments, the first side 240a and the second side 240b of each of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243 coincide with the side of the virtual quadrilateral 250. That is, the first side 240a of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243 are on the same straight line, the second side 240b of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243 are on the same straight line, and the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243 are arranged side by side and aligned in the second direction Y, so that the distribution of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243 is more uniform, further improving the display effect of the display panel 10.

[0073] Optionally, the isolation opening 240, when projected onto the substrate 100, also has a third side 240c and a fourth side 240d that are disposed opposite each other in the second direction Y. The third side 240c of the second isolation opening 242 and the fourth side 240d of the third isolation opening 243 coincide with the side of the virtual quadrilateral 250, thereby improving the uniformity of the distribution of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243.

[0074] Please refer to Figure 8, which is a partial top view of the display panel in another embodiment.

[0075] As shown in Figure 8, in some optional embodiments, the isolation opening 240, when projected onto the substrate 100, also has four arcuate sides 240e located between each pair of the first side 240a, the second side 240b, the third side 240c, and the fourth side 240d, to form a rounded rectangle.

[0076] In these optional embodiments, an arc-shaped edge 240e is provided between any two adjacent sides of the first side 240a, the second side 240b, the third side 240c, and the fourth side 240d, so that the transition between two adjacent sides is smooth and easy to manufacture.

[0077] Optionally, the virtual quadrilateral 250 is a rectangle, which further improves the even distribution of the first isolation opening 241, the second isolation opening 242 and the third isolation opening 243, and further improves the display effect of the display panel 10.

[0078] Please refer to Figure 9, which is a partial top view of the display panel in another embodiment.

[0079] As shown in Figure 9, in some optional embodiments, the second light-emitting unit 312 and the third light-emitting unit 313 are located on the same side of the first light-emitting unit 311.

[0080] In these optional embodiments, when the second light-emitting unit 312 and the third light-emitting unit 313 are located on the same side of the first light-emitting unit 311, the sum of the first sub-width D1 and the second sub-width D2 is less than the third sub-width D3. That is, the width of the isolation structure 201 between the first light-emitting unit 311 and the fourth light-emitting unit 314 adjacent in the first direction X is larger, which reduces the resistance of the isolation structure 201 located between the first light-emitting unit 311 and the fourth light-emitting unit 314 and extending in the second direction Y, and reduces the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0081] Furthermore, the second light-emitting unit 312 and the third light-emitting unit 313 are located on the same side of the first light-emitting unit 311, which can reduce the spacing between the second light-emitting unit 312 and the third light-emitting unit 313, and reduce the spacing between the different color light-emitting units 310 used to form the display unit to improve the display effect.

[0082] Please refer to Figure 10, which is a partial top view of the display panel in another embodiment.

[0083] As shown in Figure 10, in some optional embodiments, a plurality of second light-emitting units 312 and a plurality of third light-emitting units 313 are alternately arranged along the first direction X to form a first pixel group 350, a plurality of first light-emitting units 311 and a plurality of fourth light-emitting units 314 are arranged along the first direction X to form a second pixel group 360, and the first pixel group 350 and the second pixel group 360 are alternately arranged along the second direction Y.

[0084] In these optional embodiments, in adjacent first pixel groups 350 and second pixel groups 360, the width of the isolation structure 201 between the first light-emitting unit 311 in the second pixel group 360 and the second light-emitting unit 312 located on the same side of the first light-emitting unit 311 in the second direction Y is a first sub-width D1, and the width of the isolation structure 201 between the same first light-emitting unit 311 and the third light-emitting unit 313 located on the same side of the first light-emitting unit 311 in the second direction Y is a second sub-width D2. The sum of the first sub-width D1 and the second sub-width D2 is less than the third sub-width D3, which reduces the resistance of the isolation structure 201 located between the first light-emitting unit 311 and the fourth light-emitting unit 314 and extending in the second direction Y, and reduces the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0085] Optionally, in the same first pixel group 350, the width of the isolation structure 201 between the second light-emitting unit 312 and the third light-emitting unit 313 located on one side of the same first light-emitting unit 311 and adjacent to each other is a seventh sub-width D7. The seventh sub-width D7 is greater than the sum of the first sub-width D1 and the second sub-width D2, which reduces the resistance of the isolation structure 201 between the second light-emitting unit 312 and the third light-emitting unit 313 located on the same side of the same first light-emitting unit 311 and extending in the second direction Y, and reduces the voltage drop of the isolation structure 201, thereby reducing the overall power consumption of the display panel 10.

[0086] Optionally, as mentioned above, the first light-emitting unit 311, the second light-emitting unit 312, and the third light-emitting unit 313 emit different colors. For example, the first light-emitting unit 311 emits blue light, the second light-emitting unit 312 emits green light, and the third light-emitting unit 313 emits red light.

[0087] Optionally, as mentioned above, the fourth light-emitting unit 314 and the first light-emitting unit 311 emit the same color.

[0088] Please refer to Figures 2 and 11 together. Figure 11 is a partial top view of the display panel in another embodiment.

[0089] As shown in Figures 2 and 11, in some optional embodiments, adjacent light-emitting units 310 have a first region 11 and a second region 12, the width of the isolation structure 201 located in the first region 11 is greater than the width of the isolation structure 201 located in the second region 12, and the width of the pixel limiting portion 510 located in the first region 11 is greater than the width of the pixel limiting portion 510 located in the second region 12.

[0090] The width of the pixel limiting portion 510 refers to the maximum size of the pixel limiting portion 510 in the direction from which one of the two pixel openings 520 on both sides of the pixel limiting portion 510 points to the other adjacent pixel opening 520.

[0091] In these optional embodiments, within the first region 11, where the pixel limiting portion 510 has a larger width, the width of the isolation structure 201 is set to be larger, achieving a differentiated design of the width of the isolation structure 201 in the first region 11 and the second region 12. This reduces the resistance of the isolation structure 201 in the first region 11, thereby reducing the voltage drop of the isolation structure 201 and lowering the overall power consumption of the display panel 10. For example, if the width of the pixel limiting portion 510 in the first region 11 is 'a' and the width of the isolation structure 201 is 'b', and the width of the pixel limiting portion 510 in the second region 12 is 'c' and the width of the isolation structure 201 is 'd', then when 'a' is greater than 'c', 'b' is greater than 'd', making the width of the isolation structure 201 more compatible with the width of the pixel limiting portion 510. Furthermore, this ensures that the distance from the edge of the pixel opening 520 to the edge of the isolation opening 240 is the same in different regions, making the light emission effect of the isolation structure 201 on different light-emitting units 310 more consistent, thus improving the uniformity of the display on the display panel 10.

[0092] In some optional embodiments, the ratio of the width of the isolation structure 201 located in the first region 11 to the width of the pixel limiting portion 510 is greater than or equal to the ratio of the width of the isolation structure 201 located in the second region 12 to the width of the pixel limiting portion 510, for example, a / b is greater than b / d.

[0093] In these optional embodiments, the ratio of the width of the isolation structure 201 to the width of the pixel limiting portion 510 is set to be larger in the first region 11 relative to the second region 12. Since the width of the pixel limiting portion 510 in the first region 11 is greater than the width of the pixel limiting portion 510 in the second region 12, the width of the isolation structure 201 in the first region 11 is further increased, realizing the design of maximizing the width of the isolation structure 201 in the first region 11. This further reduces the resistance of the isolation structure 201 in the first region 11, thereby reducing the voltage drop of the isolation structure 201 and reducing the overall power consumption of the display panel 10.

[0094] Optionally, the width of the isolation structure 201 in the first region 11 is greater than or equal to 1.5 times the width of the isolation structure 201 in the second region 12. For example, the width of the isolation structure 201 in the first region 11 is 1.5 times, 2.0 times, 2.2 times, 2.3 times, or 3 times the width of the isolation structure 201 in the second region 12, thereby further increasing the width of the isolation structure 201 in the first region 11 and further reducing the resistance of the isolation structure 201 in the first region 11, so as to reduce the voltage drop of the isolation structure 201 and thus reduce the overall power consumption of the display panel 10.

[0095] Optionally, the ratio of the width of the isolation structure 201 located between two adjacent light-emitting units 310 to the width of the pixel limiting portion 510 is greater than or equal to 0.5. This improves the problem that if the ratio of the width of the isolation structure 201 to the width of the pixel limiting portion 510 is too small, the width of the isolation structure 201 will be too small, resulting in excessive resistance of the isolation structure 201, a large voltage drop, and high overall power consumption of the display panel 10. It can also improve the problem that if the ratio of the width of the isolation structure 201 to the width of the pixel limiting portion 510 is too small, the excessive distance between the edge of the pixel opening 520 and the edge of the isolation opening 240 will affect the light emission effect.

[0096] The pixel arrangement, isolation structure, pixel definition layer, and other structural settings in this embodiment are consistent with those described above. In the previous embodiments, the first sub-width, second sub-width, and fourth sub-width are all the widths of the isolation structure 201 located in the second region 12. Similarly, the third and fifth sub-widths in the previous embodiments are the widths of the isolation structure 201 located in the first region 11. It can be understood that a portion of the isolation structure 201 is divided into multiple first regions and multiple second regions, and the width of the aforementioned isolation structure refers to the width of the isolation structure corresponding to one first region or one second region.

[0097] Please refer to Figures 12 to 15 together. Figure 12 is a partial top view of the display panel in another embodiment; Figure 13 is a partial top view of the display panel in another embodiment; Figure 14 is a partial cross-sectional view of the display panel in another embodiment; and Figure 15 is a partial cross-sectional view of the display panel in yet another embodiment.

[0098] As shown in Figures 12 to 15, in some optional embodiments, the display panel 10 further includes: a first encapsulation layer 600 located on the side of the light-emitting layer 300 away from the substrate 100; the first encapsulation layer 600 includes an encapsulation portion 610 for encapsulating each light-emitting unit 310; at least two adjacent encapsulation portions 610 overlap in the orthographic projection portion of the substrate 100 to form an overlapping region 13; wherein, adjacent light-emitting units 310 have a first region 11 and a second region 12; the width of the isolation structure 201 of the first region 11 is greater than the width of the isolation structure 201 of the second region 12; the overlapping region 13 is located outside the orthographic projection of the isolation structure 201 of the first region 11 on the substrate 100, and the overlapping region 13 is located within the orthographic projection of the isolation structure 201 of the second region 12 on the substrate 100.

[0099] In these optional embodiments, the width of the isolation structure 201 in the first region 11 is greater than the width of the isolation structure 201 in the second region 12, thereby increasing the width of the isolation structure 201 in the first region 11 and decreasing its resistance, thus reducing the voltage drop of the isolation structure 201 and lowering the overall power consumption of the display panel 10. The overlapping region 13 is located outside the orthographic projection of the isolation structure 201 in the first region 11 onto the substrate 100. Within the first region 11, adjacent encapsulation portions 610 are spaced apart from each other on the orthographic projection onto the substrate 100. That is, the width of the isolation structure 201 corresponding to the spaced position of the two encapsulation portions 610 is larger, resulting in a larger spacing between the two adjacent encapsulation portions 610. This facilitates the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, improving the encapsulation effect. The overlapping region 13 is located within the orthographic projection of the isolation structure 201 of the second region 12 onto the substrate 100. Within the second region 12, the orthographic projections of two adjacent package portions 610 onto the substrate 100 overlap. That is, the width of the isolation structure 201 corresponding to the overlapping region 13 of the two package portions 610 is smaller, which reduces the width of the two overlapping package portions 610 on the side of the isolation structure 201 away from the substrate 100. This avoids the problem that the width of the portion of the two overlapping package portions 610 on the side of the isolation structure 201 away from the substrate 100 is too large, which would cause the portion of the package portion 610 on the side of the isolation structure 201 away from the substrate 100 to be prone to breakage under stress.

[0100] In some alternative embodiments, the ratio of the width of the overlapping region 13 to the width of the isolation structure 201 located in the second region 12 is less than or equal to 0.5. For example, 0.5, 0.4, 0.3 / 0.2, 0.1, etc.

[0101] In these optional embodiments, the ratio of the width of the overlapping region 13 to the width of the isolation structure 201 located in the second region 12 is less than or equal to 0.5. This avoids the problem that the width of the overlapping region 13 is too large, i.e., the width of the portion of the two overlapping package portions 610 on the side of the isolation structure 201 away from the substrate 100 is too large, which would cause the portion of the package portion 610 on the side of the isolation structure 201 away from the substrate 100 to be prone to breakage under stress.

[0102] Optionally, the width of the isolation structure 201 is 3μm to 26μm. For example, the width of the isolation structure 201 projected onto the substrate 100 is 3μm, 4μm, 5μm, 15μm, 18μm, 26μm, etc.

[0103] In these optional embodiments, the width of the isolation structure 201 is greater than or equal to 3 μm, which can improve the problem that if the width of the isolation structure 201 is too small, the resistance of the isolation structure 201 will be too high, the voltage drop of the isolation structure 201 will be increased, and the power consumption of the display panel 10 will be increased. It can also improve the problem that if the width of the isolation structure 201 is too small, the spacing between the two encapsulation portions 610 in the first region 11 will be too small, making subsequent filling and encapsulation with a second encapsulation layer of organic material more difficult. If the width of the isolation structure 201 is less than or equal to 26 μm, it can improve the problem that if the width of the isolation structure 201 is too large, the aperture ratio will be too low.

[0104] As shown in FIG14, in some optional embodiments, the display panel 10 further includes a driving circuit 110, a first insulating layer 120 and a first electrode 530 stacked in a direction away from the substrate 100. The first electrode 530 is located on the side of the light-emitting unit 310 facing the substrate 100 and is exposed by an isolation opening 240. The first insulating layer 120 has a through hole 130. At least a portion of the first electrode 530 is located in the through hole 130 and is electrically connected to the driving circuit 110. The orthographic projection of the through hole 130 on the substrate 100 and the orthographic projection of the isolation structure 201 located in the first region 11 on the substrate 100 at least partially overlap.

[0105] Optionally, the first insulating layer 120 includes a planarization layer, and the via 130 is formed on the planarization layer.

[0106] In these optional embodiments, the first electrode 530 is electrically connected to the driving circuit 110 through a via 130 on the first insulating layer 120, enabling the driving circuit 110 to control the signal of the first electrode 530. The first electrode 530 is exposed through the isolation opening 240, allowing it to contact the light-emitting unit 310 and serve as an electrode for controlling the light emission of the light-emitting unit 310. The via 130 is disposed within the first region 11. Because the isolation structure 201 within the first region 11 has a larger width, the first region 11 has more space for arrangement, facilitating the placement of the via 130. Therefore, placing the via 130 within the first region 11 reduces the difficulty of its placement. Furthermore, the overlap between the orthographic projection of the via 130 on the substrate 100 and the orthographic projection of the isolation structure 201 on the substrate 100 can reduce the overlap area between the orthographic projection of the via 130 on the substrate 100 and the orthographic projection of the second electrode 410 or the light-emitting unit 310 on the substrate 100. This improves the problem that the overlap between the orthographic projection of the via 130 on the substrate 100 and the orthographic projection of the second electrode 410 or the light-emitting unit 310 on the substrate 100, and the uneven surface of the second electrode 410 or the light-emitting unit 310, affects the light emission of the light-emitting unit 310 and the display effect of the display panel 10.

[0107] Optionally, within the first region 11, the orthographic projection of the driving circuit 110 onto the substrate 100 is located outside the orthographic projection of the package portion 610 onto the substrate 100. That is, the driving circuit 110 within the first region 11 is located outside the package portion 610. This avoids the problem that the driving circuit 110 within the first region 11 is located below the package portion 610, i.e., the orthographic projection of the driving circuit 110 onto the substrate 100 overlaps with the package portion 610, which would cause the package portion 610 to deform and easily break.

[0108] As shown in Figures 14 and 15, in some optional embodiments, the pixel definition layer 500 includes a first portion 511 and a second portion 512. The width of the pixel defining portion 510 located in the first region 11 is greater than the width of the pixel defining portion 510 located in the second region 12. The first portion 511 is located in the first region 11, the second portion 512 is located in the second region 12, and the width of the first electrode 530 on the side of the first portion 511 is greater than or equal to the width of the first electrode 530 on the side of the second portion 512.

[0109] In these optional embodiments, the width of the first portion 511 is greater than the width of the second portion 512, and the width of the pixel defining portion 510 within the first region 11 is set to be larger, which facilitates the provision of a wider isolation structure 201 on the pixel defining portion 510 to reduce the resistance of the isolation structure 201. Increasing the width of the first electrode 530 extending into the first portion 511 increases the overall area of ​​the first electrode 530, reduces the resistance of the first electrode 530, and reduces power consumption. Furthermore, the larger width of the first electrode 530 extending into the first portion 511 facilitates the provision of a via 130 on the side of the first portion 511 closest to the substrate 100. For example, the orthographic projection of the via 130 onto the substrate 100 lies within the orthographic projection of the first portion 511 onto the substrate 100, further reducing the impact of the via 130 on the light emission of the light-emitting unit 310.

[0110] Optionally, the orthographic projection of the isolation structure 201 onto the substrate 100 is located within the orthographic projection of the pixel limiting portion 510 onto the substrate 100, thereby improving the influence of the isolation structure 201 on the light emission of the light-emitting unit 310.

[0111] In some optional embodiments, the width of the pixel defining portion 510 is 6μm to 29μm. For example, the width of the pixel defining portion 510 is 6μm, 8μm, 15μm, 19μm, 29μm, etc.

[0112] In these optional embodiments, the width of the pixel limiting portion 510 is greater than or equal to 6 μm. This can improve the problem that if the width of the pixel limiting portion 510 is too small, the width of the isolation structure 201 located on the pixel limiting portion 510 will be too small, resulting in excessive resistance of the isolation structure 201, increased voltage drop of the isolation structure 201, and increased power consumption of the display panel 10. It can also improve the problem that if the width of the isolation structure 201 is too small, the spacing between the two encapsulation portions 610 spaced apart in the first region 11 will be too small, making subsequent filling and encapsulation with a second encapsulation layer made of organic material more difficult. If the width of the pixel limiting portion 510 is less than or equal to 29 μm, this can improve the problem that if the width of the pixel limiting portion 510 is too large, i.e., the spacing between the light-emitting units 310 is too large, the area of ​​the pixel opening 520 will be too small, resulting in an excessively low aperture ratio of the display panel 10.

[0113] In the following text, the overlapping of the encapsulation portion 610 corresponding to the two light-emitting units 310 refers to the overlapping of the orthographic projections of the two encapsulation portions 610 on the substrate 100, and the encapsulation portion 610 corresponding to the light-emitting unit 310 refers to the encapsulation portion 610 covering the light-emitting unit 310.

[0114] In some optional embodiments, the light-emitting unit 310 includes a third light-emitting unit 313, a second light-emitting unit 312 and a first light-emitting unit 311, wherein at least one of the encapsulation portions 610 corresponding to the third light-emitting unit 313 and the second light-emitting unit 312 partially overlaps with the encapsulation portion 610 corresponding to the first light-emitting unit 311.

[0115] In these optional embodiments, the third light-emitting unit 313 overlaps with the encapsulation portion 610 corresponding to the first light-emitting unit 311, thus extending the intrusion path of water, oxygen, and liquid in the area between the third light-emitting unit 313 and the first light-emitting unit 311. This makes it difficult for water, oxygen, and liquid to intrude through the portion of the encapsulation portion 610 located between the third light-emitting unit 313 and the first light-emitting unit 311, avoiding damage to the light-emitting unit 310 caused by water, oxygen, and liquid intrusion, and preventing the display panel 10 from showing dark spots; or, the second light-emitting unit 312 overlaps with the encapsulation portion 610 corresponding to the first light-emitting unit 311. The partial overlap extends the intrusion path of water, oxygen, and liquid in the area between the second light-emitting unit 312 and the first light-emitting unit 311, making it difficult for water, oxygen, and liquid to intrude through the portion of the encapsulation part 610 located between the second light-emitting unit 312 and the first light-emitting unit 311. This avoids damage to the light-emitting unit 310 caused by the intrusion of water, oxygen, and liquid, and prevents the display panel 10 from having dark spots. Alternatively, the third light-emitting unit 313 partially overlaps with the encapsulation part 610 corresponding to the first light-emitting unit 311, and the second light-emitting unit 312 partially overlaps with the encapsulation part 610 corresponding to the first light-emitting unit 311.

[0116] To provide sufficient space for the arrangement of vias 130 and to reduce the impact of vias 130 on the light emission of the light-emitting unit 310, vias 130 are disposed in the first region 11 and at least partially overlap with the isolation structure 201. For example, optionally, the vias 130 corresponding to the third light-emitting unit 313 and the isolation structure 201 located in the first region 11 have at least partially overlapped projections on the substrate 100. Alternatively, the vias 130 corresponding to the second light-emitting unit 312 and the isolation structure 201 located in the first region 11 have at least partially overlapped projections on the substrate 100. Alternatively, the vias 130 corresponding to the first light-emitting unit 311 and the isolation structure 201 located in the first region 11 have at least partially overlapped projections on the substrate 100.

[0117] As shown in Figures 12 and 13, when multiple third light-emitting units 313 and multiple second light-emitting units 312 are alternately arranged along the first direction X to form a first pixel group 350, and multiple first light-emitting units 311 are arranged along the first direction X to form a second pixel group 360, and the first pixel group 350 and the second pixel group 360 are alternately arranged along the second direction Y, the display panel 10 includes multiple arrayed pixel units 370. Each pixel unit 370 includes a first light-emitting unit 311, a third light-emitting unit 313 and a second light-emitting unit 312 located on the same side of the first light-emitting unit 311 in the second direction Y. In two adjacent pixel units 370, the encapsulation part 610 corresponding to the third light-emitting unit 313 of one unit overlaps with the encapsulation part 610 corresponding to the second light-emitting unit 312 of the other unit to form an overlapping area 13.

[0118] In these optional embodiments, in two adjacent pixel units 370 in the first direction X, the area between the third light-emitting unit 313 of one and the second light-emitting unit 312 of the other is located in the second region 12, where the width of the isolation structure 201 is smaller. The overlapping region 13 extends the intrusion path of water, oxygen, and chemicals in the area between the third light-emitting unit 313 of one and the second light-emitting unit 312 of the other in two adjacent pixel units 370, making it difficult for water, oxygen, and chemicals to intrude through the portion of the encapsulation part 610 located between the third light-emitting unit 313 and the second light-emitting unit 312, thus avoiding damage to the light-emitting unit 310 caused by the intrusion of water, oxygen, and chemicals, and preventing the display panel 10 from having dark spots.

[0119] In some optional embodiments, within the same pixel unit 370, the encapsulation portions 610 corresponding to the third light-emitting unit 313 and the second light-emitting unit 312 are spaced apart.

[0120] In these optional embodiments, within the same pixel unit 370, the area between the third light-emitting unit 313 and the second light-emitting unit 312 is located in the first region 11. In this region, the width of the isolation structure 201 is set to be larger, and the spacing between two adjacent encapsulation portions 610 is larger, which is beneficial for the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, thereby improving the encapsulation effect.

[0121] Optionally, the encapsulation portions 610 corresponding to adjacent first light-emitting units 311 are spaced apart, and the area between two adjacent first light-emitting units 311 is located in the first region 11. In this region, the width of the isolation structure 201 is set to be larger, and the spacing between two adjacent encapsulation portions 610 is larger, which is conducive to the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, thereby improving the encapsulation effect.

[0122] In some optional embodiments, within the same pixel unit 370, the encapsulation portion 610 corresponding to the third light-emitting unit 313 overlaps with the encapsulation portion 610 corresponding to the adjacent first light-emitting unit 311, and / or, the encapsulation portion 610 corresponding to the second light-emitting unit 312 overlaps with the encapsulation portion 610 corresponding to the adjacent first light-emitting unit 311.

[0123] In these optional embodiments, within the same pixel unit 370, the encapsulation portion 610 corresponding to the third light-emitting unit 313 overlaps with the encapsulation portion 610 corresponding to the adjacent first light-emitting unit 311. That is, within the same pixel unit 370, the area between the third light-emitting unit 313 and the adjacent first light-emitting unit 311 is located in the second region 12, where the width of the isolation structure 201 is smaller. This overlapping arrangement extends the intrusion path of water, oxygen, and chemicals in the area between the third light-emitting unit 313 and the adjacent first light-emitting unit 311 within the same pixel unit 370. This makes it difficult for water, oxygen, and chemicals to intrude through the portion of the encapsulation portion 610 located between the third light-emitting unit 313 and the first light-emitting unit 311, thus avoiding damage to the light-emitting unit 310 caused by water, oxygen, and chemicals, and preventing dark spots from appearing on the display panel 10. Within the same pixel unit 370, the encapsulation portion 610 corresponding to the second light-emitting unit 312 overlaps with the encapsulation portion 610 corresponding to the adjacent first light-emitting unit 311. That is, within the same pixel unit 370, the area between the second light-emitting unit 312 and the adjacent first light-emitting unit 311 is located in the second region 12, where the width of the isolation structure 201 is smaller. Furthermore, the overlapping arrangement extends the intrusion path of water, oxygen, and chemicals in the area between the second light-emitting unit 312 and the adjacent first light-emitting unit 311 within the same pixel unit 370. This makes it difficult for water, oxygen, and chemicals to intrude through the portion of the encapsulation portion 610 located between the second light-emitting unit 312 and the first light-emitting unit 311, thus preventing damage to the light-emitting unit 310 caused by water, oxygen, and chemicals, and avoiding the problem of dark spots appearing on the display panel 10.

[0124] In some alternative embodiments, within pixel unit 370, the via 130 located between adjacent third light-emitting unit 313 and second light-emitting unit 312 has its orthogonal projection on substrate 100 outside the orthogonal projection of package portion 610 on substrate 100.

[0125] In these optional embodiments, the via 130 located between the third light-emitting unit 313 and the second light-emitting unit 312 adjacent to each other in the pixel unit 370 is disposed in a region outside the encapsulation portion 610, so as to avoid the via 130 being disposed below the encapsulation portion 610, that is, the orthogonal projection of the via 130 on the substrate 100 overlapping with the encapsulation portion 610, which would cause the encapsulation portion 610 to deform and break easily.

[0126] Due to the presence of via 130, some material of the first electrode 530 is trapped in via 130 to form a depression, which in turn causes depressions to form on the pixel limiting part 510 and the isolation structure 201, making the packaging part 610 corresponding to via 130 prone to sagging and deformation.

[0127] Within pixel unit 370, the via 130 located between adjacent third light-emitting units 313 and second light-emitting units 312 can have various configurations. For example, optionally, within the same pixel unit 370, the orthographic projection of the via 130 corresponding to the third light-emitting unit 313 onto the substrate 100 is located between the orthographic projections of the third light-emitting unit 313 and the second light-emitting unit 312 onto the substrate 100. Alternatively, optionally, within the same pixel unit 370, the orthographic projection of the via 130 corresponding to the second light-emitting unit 312 onto the substrate 100 is located between the orthographic projections of the third light-emitting unit 313 and the second light-emitting unit 312 onto the substrate 100. Alternatively, optionally, at least a portion of the orthographic projection of the via 130 corresponding to the first light-emitting unit 311 onto the substrate 100 is located between the orthographic projections of the third light-emitting unit 313 and the second light-emitting unit 312 onto the substrate 100. All of these measures can avoid the problem that the via 130 is located below the package portion 610, i.e., the orthogonal projection of the via 130 on the substrate 100 overlaps with the package portion 610, which would cause the package portion 610 to deform and break easily.

[0128] Optionally, within the same pixel unit 370, the orthographic projection of the via 130 corresponding to the first light-emitting unit 311 onto the substrate 100 is located on the side where the orthographic projection of the first light-emitting unit 311 onto the substrate 100 faces the orthographic projection of the third light-emitting unit 313 onto the substrate 100.

[0129] Please refer to Figures 16 and 17. Figure 16 is a partial top view of the display panel in another embodiment; Figure 17 is a partial top view of the display panel in another embodiment.

[0130] As shown in Figures 16 and 17, when multiple first light-emitting units 311 are arranged along the first direction X to form a first pixel column 320, multiple second light-emitting units 312 are arranged along the first direction X to form a second pixel column 330, and multiple third light-emitting units 313 are arranged along the first direction X to form a third pixel column 340, and the first pixel column 320, second pixel column 330, and third pixel column 340 are arranged alternately along the second direction Y, the encapsulation part 610 corresponding to the first light-emitting unit 311 and the encapsulation part 610 corresponding to the adjacent second light-emitting unit 312 are overlapped. Optionally, the encapsulation part 610 corresponding to the second light-emitting unit 312 and the encapsulation part 610 corresponding to the adjacent third light-emitting unit 313 are overlapped.

[0131] In these optional embodiments, the encapsulation portion 610 corresponding to the first light-emitting unit 311 and the encapsulation portion 610 corresponding to the adjacent second light-emitting unit 312 are overlapped. The area between the first light-emitting unit 311 and the adjacent second light-emitting unit 312 is located in the second region 12, where the width of the isolation structure 201 is smaller. Furthermore, the overlapped arrangement extends the intrusion path of water, oxygen, and chemicals in the area between the first light-emitting unit 311 and the adjacent second light-emitting unit 312, making it difficult for water, oxygen, and chemicals to intrude through the portion of the encapsulation portion 610 located between the first and second light-emitting units 311 and 312. This avoids damage to the light-emitting unit 310 caused by water, oxygen, and chemicals intrusion, preventing dark spots on the display panel 10. The encapsulation portion 610 corresponding to the second light-emitting unit 312 and the encapsulation portion 610 corresponding to the adjacent third light-emitting unit 313 are overlapped. The area between the second light-emitting unit 312 and the adjacent third light-emitting unit 313 is located in the second region 12, where the width of the isolation structure 201 is smaller. Furthermore, the overlapping arrangement extends the intrusion path of water, oxygen, and chemicals in the area between the second light-emitting unit 312 and the adjacent third light-emitting unit 313. This makes it difficult for water, oxygen, and chemicals to intrude through the portion of the encapsulation part 610 located between the second light-emitting unit 312 and the third light-emitting unit 313, thus avoiding damage to the light-emitting unit 310 caused by water, oxygen, and chemicals intrusion and the problem of dark spots appearing on the display panel 10. The encapsulation part 610 corresponding to the first light-emitting unit 311 and the encapsulation part 610 corresponding to the adjacent third light-emitting unit 313 are overlapped. The area between the first light-emitting unit 311 and the adjacent third light-emitting unit 313 is located in the second region 12. In this region, the width of the isolation structure 201 is smaller. Furthermore, the overlapping arrangement extends the intrusion path of water, oxygen, and medicine in the area between the first light-emitting unit 311 and the adjacent third light-emitting unit 313, making it difficult for water, oxygen, and medicine to intrude through the part of the encapsulation part 610 located between the first light-emitting unit 311 and the third light-emitting unit 313. This avoids damage to the light-emitting unit 310 caused by the intrusion of water, oxygen, and medicine, and prevents the display panel 10 from having dark spots.

[0132] In some optional embodiments, the encapsulation portions 610 corresponding to adjacent first light-emitting units 311 are spaced apart; optionally, the encapsulation portions 610 corresponding to adjacent second light-emitting units 312 are spaced apart; optionally, the encapsulation portions 610 corresponding to adjacent third light-emitting units 313 are spaced apart.

[0133] In these optional embodiments, the encapsulation portions 610 corresponding to adjacent first light-emitting units 311 are spaced apart. The area between two adjacent first light-emitting units 311 is located in a first region 11. In this region, the width of the isolation structure 201 is larger, and the spacing between two adjacent encapsulation portions 610 is larger, which facilitates the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, thereby improving the encapsulation effect. Similarly, the encapsulation portions 610 corresponding to adjacent second light-emitting units 312 are spaced apart. The area between two adjacent second light-emitting units 312 is located in the first region 11. In this region, the width of the isolation structure 201 is larger, and the spacing between two adjacent encapsulation portions 610 is larger, which facilitates the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, thereby improving the encapsulation effect. The encapsulation portions 610 corresponding to adjacent third light-emitting units 313 are spaced apart. The area between two adjacent third light-emitting units 313 is located in the first region 11. In this region, the width of the isolation structure 201 is larger and the spacing between two adjacent encapsulation portions 610 is larger, which is beneficial for the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, thereby improving the encapsulation effect.

[0134] Optionally, the via 130 corresponding to the first light-emitting unit 311 is located between the orthographic projections of two adjacent first light-emitting units 311 on the substrate 100. Since the isolation structure 201 between two adjacent first light-emitting units 311 is wider and the spacing between two adjacent first light-emitting units 311 is larger, it is convenient to set the via 130 of the first light-emitting unit 311.

[0135] Optionally, the via 130 corresponding to the second light-emitting unit 312 is located between the orthographic projections of two adjacent second light-emitting units 312 on the substrate 100. Since the isolation structure 201 between two adjacent second light-emitting units 312 is wider and the spacing between two adjacent second light-emitting units 312 is larger, it is convenient to set the via 130 of the second light-emitting unit 312.

[0136] Optionally, the via 130 corresponding to the third light-emitting unit 313 is located between the orthographic projections of two adjacent third light-emitting units 313 on the substrate 100. Since the isolation structure 201 between two adjacent third light-emitting units 313 is wider and the spacing between two adjacent third light-emitting units 313 is larger, it is convenient to set the via 130 of the third light-emitting unit 313.

[0137] Please refer to Figures 18 and 19. Figure 18 is a partial cross-sectional view of the display panel in another embodiment; Figure 19 is a partial cross-sectional view of the display panel in yet another embodiment.

[0138] As shown in Figures 18 and 19, optionally, the encapsulation portion 610 includes an extension portion 611 located on the side of the isolation structure 201 away from the substrate 100 and spaced apart from the isolation structure 201. At least two adjacent extension portions 611 overlap to form an overlapping area 13, thereby extending the intrusion path of water, oxygen and liquid medicine and improving the encapsulation effect.

[0139] In some alternative embodiments, the isolation structure 201 of the first region 11 has a first top surface 202 facing away from the substrate 100, and the sum of the widths of the two extensions 611 located on the side of the first top surface 202 facing away from the substrate 100 is less than or equal to the width of the first top surface 202.

[0140] The width of the extension 611 refers to the size of the extension 611 in the direction of its corresponding isolation opening 240 pointing to the isolation opening 240, and the width of the first top surface 202 refers to the size of the first top surface 202 in the direction of the isolation opening 240 pointing to the isolation opening 240.

[0141] In these alternative embodiments, the sum of the widths of the two extensions 611 located on the side of the first top surface 202 away from the substrate 100 is less than or equal to the width of the first top surface 202, so that the two extensions 611 have a small width, which can avoid the problem that the width of the two overlapping extensions 611 is too large, causing the extensions 611 to be prone to breakage under stress.

[0142] As shown in Figure 18, optionally, the isolation structure 201 of the first region 11 has a first top surface 202 facing away from the substrate 100. The first top surface 202 is symmetrical about the first reference surface 14. The first reference surface 14 is perpendicular to the substrate 100 and extends through the first top surface 202. The encapsulation portions 610 corresponding to the light-emitting units 310 located on both sides of the isolation structure 201 of the first region 11 are respectively disposed on both sides of the first reference surface 14. That is, in the first region 11, two adjacent encapsulation portions 610 are spaced apart on the first top surface 202.

[0143] As shown in Figure 19, optionally, the isolation structure 201 of the second region 12 has a second top surface 203 facing away from the substrate 100. The second top surface 203 is symmetrical about the second reference surface 15. The second reference surface 15 is perpendicular to the substrate 100 and extends through the second top surface 203. At least one of the encapsulation portions 610 corresponding to the light-emitting units 310 on both sides of the isolation structure 201 of the second region 12 overlaps with the second reference surface 15. That is, in the second region 12, two adjacent encapsulation portions 610 are overlapped on the second top surface 203, and the overlapping area 13 overlaps with the second reference surface 15, so as to avoid the problem that the width of one of the encapsulation portions 610 on the isolation structure 201 is too large, which would make it easy to break under stress.

[0144] As shown in Figures 1 to 19, in some optional embodiments, the display panel 10 further includes a second electrode layer 400 located on the side of the light-emitting layer 300 away from the substrate 100. The second electrode layer 400 includes a second electrode 410 located in the isolation opening 240, and the second electrode 410 is electrically connected to the isolation structure 201.

[0145] In these optional embodiments, the isolation structure 201 isolates the second electrode layer 400 to form mutually spaced second electrodes 410. The mutually spaced second electrodes 410 are electrically connected through the isolation structure 201 to form a full-surface electrode, ensuring the normal light emission of the light-emitting unit 310. One of the second electrode 410 and the first electrode 530 serves as the anode of the light-emitting unit 310, and the other serves as the cathode of the light-emitting unit 310. In this embodiment, the second electrode 410 is used as the anode of the light-emitting unit 310, and the first electrode 530 is used as the cathode of the light-emitting unit 310 for illustrative purposes.

[0146] In some alternative embodiments, the orthographic projection of the light-emitting unit 310 onto the substrate 100 is located within the orthographic projection of the second electrode 410 onto the substrate 100.

[0147] In these optional embodiments, the orthographic projection of the light-emitting unit 310 onto the substrate 100 is located within the orthographic projection of the second electrode 410 onto the substrate 100, that is, the first electrode 530 is disposed over the light-emitting unit 310 to serve as the electrode of the light-emitting unit 310, thereby ensuring the normal light emission of the light-emitting unit 310 and improving the display effect of the display panel 10.

[0148] Optionally, the light-emitting unit 310 and the isolation structure 201 are spaced apart, that is, each light-emitting unit 310 is spaced apart from the other, which reduces crosstalk of charge carriers between each light-emitting unit 310 and improves the color crosstalk problem of the light-emitting unit 310.

[0149] Optionally, the material of the first encapsulation layer 600 may include inorganic materials. Inorganic materials have good density and good barrier properties against water vapor and oxygen.

[0150] Optionally, the display panel 10 further includes: a second encapsulation layer located on the side of the first encapsulation layer 600 away from the substrate 100; and a third encapsulation layer located on the side of the second encapsulation layer away from the substrate 100. The display panel 10 adopts a three-layer encapsulation, which has better encapsulation performance and reduces the possibility of water and oxygen intrusion.

[0151] Optionally, the material of the second encapsulation layer may include organic materials.

[0152] Optionally, the material of the third encapsulation layer may include inorganic materials. The first encapsulation layer 600, the second encapsulation layer, and the third encapsulation layer are encapsulated using inorganic materials, organic materials, and inorganic materials, respectively, to form a TFE (Thin Film Encapsulation) encapsulation structure, further improving the encapsulation performance.

[0153] In some alternative embodiments, the isolation structure 201 includes a first layer 210 and a second layer 220 located on the side of the first layer 210 away from the substrate 100, wherein the surface of the first layer 210 away from the substrate 100 is within the orthographic projection of the substrate 100, and the surface of the second layer 220 near the substrate 100 is within the orthographic projection of the substrate 100.

[0154] In these optional embodiments, the isolation structure 201 includes a first layer 210 and a second layer 220 located on the side of the first layer 210 away from the substrate 100. The first layer 210 and the second layer 220 are stacked to form the isolation structure 201. The first layer 210, which is disposed close to the substrate 100, has its orthographic projection on the substrate 100 located within the orthographic projection of the second layer 220 on the substrate 100. The area of ​​the second layer 220 is larger than the area of ​​the first layer 210. The second layer 220 covers the surface of the first layer 210 that is close to the second layer 220. At this time, the first layer 210 is recessed relative to the second layer 220 in a direction away from the isolation opening 240.

[0155] In this application, the sub-width of the isolation structure is the larger of the orthographic projection of the surface of the second layer on the substrate away from the substrate and the orthographic projection of the surface on the substrate near the substrate. Correspondingly, the isolation opening is the opening formed by the edge of the larger of the orthographic projection of the surface of the second layer on the substrate away from the substrate and the orthographic projection of the surface on the substrate near the substrate.

[0156] When the light-emitting layer 300 is fabricated, a large drop is generated at the edge of the isolation structure 201, and the first layer 210 is recessed relative to the second layer 220. The light-emitting layer 300 is difficult to connect at the edge of the isolation structure 201, resulting in breakage. The breakage of the light-emitting layer 300 forms mutually disconnected light-emitting units 310, thereby reducing crosstalk of charge carriers in the light-emitting layer 300, improving the display effect of the display panel 10, and fabricating the light-emitting unit 310 does not require the use of a precision mask, which can reduce the development and use of precision masks and reduce the fabrication cost.

[0157] Optionally, the first layer 210 includes a conductive material, such as a non-metallic conductive material or a metallic conductive material.

[0158] In some alternative embodiments, the second layer 220 includes a conductive material or an insulating material.

[0159] In these alternative embodiments, the second layer 220 includes a conductive material, such as a non-metallic conductive material or a metallic conductive material. When the second layer 220 is a non-metallic conductive material or an insulating material, it is difficult to etch the second layer 220 during the wet etching process of the first layer 210 with an etching solution, thereby making it easier for the first layer 210 to be recessed relative to the second layer 220.

[0160] In some alternative embodiments, both the first layer 210 and the second layer 220 comprise metallic materials, and the materials of the first layer 210 and the second layer 220 are different.

[0161] In these optional embodiments, when both the first layer 210 and the second layer 220 are made of metallic materials, the first layer 210 can be wet-etched using an etching solution. By adjusting the etching solution, the etching rate of the second layer 220 can be made lower than that of the first layer 210. Because the etching rate of the first layer 210 is higher, even if the second layer 220 is etched to some extent during wet etching, the first layer 210 is etched faster, thus making the first layer 210 recessed relative to the second layer 220.

[0162] Optionally, at least a portion of the width of the second layer 220 is 3μm to 26μm. For example, the width of the second layer 220 projected onto the substrate 100 is 3μm, 4μm, 5μm, 6μm, etc. The width of the second layer 220 refers to the dimension of the second layer 220 in the direction from the isolation opening 240 to the isolation opening 240.

[0163] In these optional embodiments, the width of the second layer 220 is greater than or equal to 3 μm, which can improve the problem that the resistance of the isolation structure 201 is too high, the voltage drop of the isolation structure 201 is increased, and the power consumption of the display panel 10 is increased due to the small width of the isolation structure 201. It can also improve the problem that the small width of the isolation structure 201 leads to a small gap between the two encapsulation portions 610 in the first region 11, making it difficult to fill and encapsulate with a second encapsulation layer made of organic material. The width of the second layer 220 is less than or equal to 26 μm, which can improve the problem that the width of the two overlapping encapsulation portions 610 in the second region 12 is too large, making the portion of the encapsulation portion 610 on the side of the isolation structure 201 away from the substrate 100 prone to breakage under stress.

[0164] Please refer to Figure 20, which is a partial cross-sectional view of the display panel in another embodiment.

[0165] As shown in FIG20, in some optional embodiments, the isolation structure 201 further includes a third layer 230 located on the side of the first layer 210 facing the substrate 100, wherein the orthographic projection of the surface of the first layer 210 near the substrate 100 onto the substrate 100 lies within the orthographic projection of the surface of the third layer 230 away from the substrate 100.

[0166] In these alternative embodiments, because the first layer 210 has a faster etching rate, the resulting etching waste is more likely to enter other parts of the display panel 10, causing adverse effects. With the third layer 230, the first layer 210 can adhere better to the third layer 230, and the resulting etching waste falls onto the third layer 230, making it easier to clean.

[0167] Optionally, the light-emitting layer 300 includes an electron injection layer (EIL), an electron transport layer (ETL), a light-emitting material layer, a hole injection layer (HIL), and a hole transport layer (HTL).

[0168] As shown in Figures 1 to 20, this application embodiment provides a display panel 10, which includes: a substrate 100; an isolation layer 200 located on one side of the substrate 100, the isolation layer 200 including an isolation structure 201 and an isolation opening 240 formed by the isolation structure 201; a pixel definition layer 500 located on one side of the substrate 100, the pixel definition layer 500 including a pixel limiting portion 510 and a pixel opening 520 formed by the pixel limiting portion 510, at least a portion of the pixel opening 520 and the isolation opening 240 correspond one-to-one and are interconnected; and a light-emitting layer 300 located on one side of the substrate 100, the light-emitting layer 300 including light-emitting units 310 located at least partially in the pixel opening 520, wherein adjacent light-emitting units 310 have a first region 11 and a second region 12, the width of the isolation structure 201 located in the first region 11 is greater than the width of the isolation structure 201 located in the second region 12, and the width of the pixel limiting portion 510 located in the first region 11 is greater than the width of the pixel limiting portion 510 located in the second region 12.

[0169] According to an embodiment of this application, the display panel 10 includes a substrate 100, an isolation layer 200, a pixel definition layer 500, and a light-emitting layer 300. The isolation structure 201 of the isolation layer 200 forms an isolation opening 240, and at least a portion of the light-emitting units 310 of the light-emitting layer 300 is located in the isolation opening 240, which can improve the problem of easy crosstalk between adjacent light-emitting units 310. The pixel defining portion 510 of the pixel definition layer 500 forms a pixel opening 520 to house the light-emitting units 310, enabling the light-emitting units 310 to emit light normally. Furthermore, the pixel defining portion 510 defines the placement area of ​​each light-emitting unit 310, reducing color crosstalk between the light-emitting units 310. Within the first region 11, which has a larger width in the pixel limiting portion 510, the width of the isolation structure 201 is set to be larger, thereby achieving a width difference design for the isolation structure 201 in the first region 11 and the second region 12. This reduces the resistance of the isolation structure 201 in the first region 11, thereby reducing the voltage drop of the isolation structure 201 and reducing the overall power consumption of the display panel 10.

[0170] The display panel 10 provided in this embodiment and the display panel 10 in any of the above embodiments can be cross-referenced. For example, the arrangement of the isolation structure 201, the light-emitting unit 310, the isolation opening 240, and the first encapsulation layer 600 can be referred to above, and will not be repeated here.

[0171] As shown in Figures 1 to 20, this application embodiment provides a display panel 10, which further includes: a substrate 100; an isolation structure 201 located on one side of the substrate 100, the isolation structure 201 enclosing an isolation opening 240; a light-emitting layer 300 located on one side of the substrate 100, the light-emitting layer 300 including light-emitting units 310 located in the isolation opening 240; and a first encapsulation layer 600 located on the side of the light-emitting layer 300 facing away from the substrate 100, the first encapsulation layer 600 including an encapsulation portion for encapsulating each light-emitting unit 310. 610, at least two adjacent encapsulation portions 610 overlap in the orthographic projection portion of the substrate 100 to form an overlapping region 13, wherein adjacent light-emitting units 310 have a first region 11 and a second region 12, the width of the isolation structure 201 of the first region 11 is greater than the width of the isolation structure 201 of the second region 12, the overlapping region 13 is located within the orthographic projection of the isolation structure 201 of the first region 11 on the substrate 100, and the overlapping region 13 is located outside the orthographic projection of the isolation structure 201 of the second region 12 on the substrate 100.

[0172] According to an embodiment of this application, the display panel 10 includes a substrate 100, an isolation layer 200, and a light-emitting layer 300. The isolation structure 201 of the isolation layer 200 forms an isolation opening 240, and at least a portion of the light-emitting units 310 of the light-emitting layer 300 is located within the isolation opening 240, which can improve the problem of easy crosstalk between adjacent light-emitting units 310. The width of the isolation structure 201 in the first region 11 is greater than the width of the isolation structure 201 in the second region 12, thereby increasing the width of the isolation structure 201 in the first region 11 and decreasing its resistance, thus reducing the voltage drop of the isolation structure 201 and consequently reducing the overall power consumption of the display panel 10. The overlapping region 13 is located outside the orthographic projection of the isolation structure 201 in the first region 11 onto the substrate 100. Within the first region 11, two adjacent encapsulation portions 610 are spaced apart from each other on the orthographic projection onto the substrate 100. That is, the width of the isolation structure 201 corresponding to the spaced position of the two encapsulation portions 610 is larger, which makes the spacing between the two adjacent encapsulation portions 610 larger. This is beneficial for the subsequent filling of the second encapsulation layer of organic material between the encapsulation portion 610 and the isolation structure 201, thereby improving the encapsulation effect. The overlapping region 13 is located within the orthographic projection of the isolation structure 201 of the second region 12 onto the substrate 100. Within the second region 12, the orthographic projections of two adjacent package portions 610 onto the substrate 100 overlap. That is, the width of the isolation structure 201 corresponding to the overlapping region 13 of the two package portions 610 is smaller, which reduces the width of the two overlapping package portions 610 on the side of the isolation structure 201 away from the substrate 100. This avoids the problem that the width of the portion of the two overlapping package portions 610 on the side of the isolation structure 201 away from the substrate 100 is too large, which would cause the portion of the package portion 610 on the side of the isolation structure 201 away from the substrate 100 to be prone to breakage under stress.

[0173] The display panel 10 provided in this embodiment and the display panel 10 in any of the above embodiments can be cross-referenced. For example, the arrangement of the isolation structure 201, the light-emitting unit 310, the isolation opening 240, and the first encapsulation layer 600 can be referred to above, and will not be repeated here.

Since the display device provided in the second aspect of this application includes the display panel 10 of any of the above embodiments, it has the beneficial effects of the display panel 10 of any of the above embodiments, which will not be elaborated further here.
