Display panel

Abstract

The present disclosure provides a display panel. The display panel comprises a substrate, and an isolation structure, a pixel definition layer and a plurality of light-emitting devices which are located on the substrate. The light-emitting devices each comprise a first electrode, a light-emitting functional layer and a second electrode which are sequentially stacked on the substrate. The isolation structure comprises a plurality of isolation openings, and the pixel definition layer comprises pixel openings in communication with the isolation openings. The light-emitting functional layer and the second electrode of each light-emitting device are limited in an isolation opening and a pixel opening. At the pixel opening and the isolation opening in which at least one of the light-emitting devices is located, orthographic projections of at least two positions on the substrate are present in an edge of the pixel opening, and distances from the orthographic projections to the orthographic projection of an edge of the isolation opening on the substrate are different. In the display panel, by offsetting the pixel openings, the difficulty of joining a second electrode and an isolation structure on the side is further reduced, thereby reducing the impedance between the second electrode and the isolation structure.

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411849427.9 entitled “Display Panel”, filed on December 13, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of display technology, and more specifically, to a display panel. Background Technology

[0004] Organic light-emitting diodes (OLEDs) are organic thin-film electroluminescent devices. They have attracted great attention and are widely used in electronic display products due to their advantages such as simple fabrication process, low cost, low power consumption, high brightness, wide viewing angle, high contrast and flexible display capability.

[0005] However, current electronic display products are limited by their structural design, making it difficult to guarantee display performance. Summary of the Invention

[0006] This disclosure provides a display panel comprising a substrate, an isolation structure, a pixel defining layer, and a plurality of light-emitting devices disposed on the substrate. Each light-emitting device includes a first electrode, a light-emitting functional layer, and a second electrode sequentially stacked on the substrate. The isolation structure includes a plurality of isolation openings. The pixel defining layer includes pixel openings communicating with the isolation openings. The light-emitting functional layer and the second electrode of the light-emitting device are located within the isolation openings and the pixel openings. At at least one pixel opening and isolation opening containing a light-emitting device, at least two positions on the substrate have orthographic projections from the edge of the pixel opening to different distances from the orthographic projections of the edge of the isolation opening onto the substrate.

[0007] In the above scheme, by offsetting the pixel opening, the light-emitting device can be shifted to the side where the second electrode and the isolation structure are easier to connect (high connection quality), thereby further reducing the difficulty of connecting the second electrode and the isolation structure on that side. Thus, the impedance between the second electrode and the isolation structure can be reduced without increasing the thickness of the second electrode.

[0008] A second aspect of this disclosure provides a display panel including a substrate, an isolation structure, a pixel defining layer, and a plurality of light-emitting devices located on the substrate. Each light-emitting device includes a first electrode, a light-emitting functional layer, and a second electrode sequentially stacked on the substrate. The isolation structure includes a plurality of isolation openings. The pixel defining layer includes a pixel opening communicating with the isolation openings. The light-emitting functional layer and the second electrical limit of the light-emitting device are located within the isolation openings and the pixel openings. For the same pixel opening and isolation opening containing the same light-emitting device, the centroid of the orthographic projection of the pixel opening onto the substrate is located outside the centroid of the orthographic projection of the isolation opening onto the substrate.

[0009] In the above scheme, by offsetting the pixel opening, the light-emitting device can be shifted to the side where the second electrode and the isolation structure are easier to connect (high connection quality), thereby further reducing the difficulty of connecting the second electrode and the isolation structure on that side. Thus, the impedance between the second electrode and the isolation structure can be reduced without increasing the thickness of the second electrode.

[0010] A third aspect of this disclosure provides a display panel including a substrate, an isolation structure, a pixel defining layer, and a plurality of light-emitting devices disposed on the substrate. The light-emitting devices include a first electrode, a light-emitting functional layer, and a second electrode sequentially stacked on the substrate. The isolation structure includes a plurality of isolation openings, with the light-emitting functional layer and the second electrode of the light-emitting device located within the isolation openings. At at least one isolation opening, the centroid of the orthographic projection of the first electrode onto the substrate is located outside the centroid of the orthographic projection of the isolation opening onto the substrate.

[0011] In the above scheme, the first electrode can be offset along with the pixel opening (the offset direction and size can be the same or different) to adjust the distribution of the part of the pixel defining layer that covers the edge of the first electrode (which will be raised by the first electrode) to adjust the impedance at the connection points of the second electrode and the isolation structure at different positions.

[0037] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0038] In display products, some functional film layers in light-emitting devices are formed by vapor deposition. Each light-emitting device has multiple functional film layers, and the materials of some functional film layers (such as the light-emitting layer) in light-emitting devices that emit different light are different. Therefore, when vapor-depositing these functional film layers through a mask (such as a fine mask), multiple alignments are required. In order to solve the positional offset problem caused by alignment accuracy errors, sufficient space (safety margin related to alignment error) needs to be reserved between different light-emitting devices to ensure that the actual light-emitting area of ​​the light-emitting device can have a certain overlap with the designed position (design area). This is equivalent to compressing the designed area of ​​the light-emitting area of ​​the light-emitting device, which not only limits the light-emitting area of ​​the light-emitting device, but also prevents the arrangement density of the light-emitting devices from being further increased, thus making it difficult to further improve the PPI (pixel density) of the display panel.

[0039] In this disclosure, by setting an isolation structure to separate the functional film layers of adjacent light-emitting devices, in the evaporation process of the functional film layers, it is only necessary to perform evaporation on the entire display panel, without the need to prepare the functional film layer of each light-emitting device separately with the help of a mask. This process does not need to consider the alignment accuracy problem during evaporation, thereby allowing the gap between the light-emitting devices to be designed to be smaller, so as to increase PPI.

[0040] In the fabrication process of light-emitting devices, the cathode (such as the second electrode described below) needs to overlap with the isolation structure. However, the edge of the cathode is blocked by the isolation structure. Therefore, if the edge of the cathode has sufficient thickness to reduce the impedance between it and the isolation structure during the evaporation process, the thickness of the film layer to be evaporated in each evaporation process will be larger, which will increase the thickness of the central region of the cathode accordingly. This will severely reduce the transmittance of the cathode. Conversely, if the thickness of the central region of the cathode is reduced, the thickness of the cathode edge will be insufficient, thereby increasing the impedance between the cathode and the isolation structure, and even causing poor overlap between the cathode and the isolation structure.

[0041] Furthermore, in the process of fabricating light-emitting devices based on isolation structures, the light-emitting devices are fabricated in batches. Therefore, multiple patterning processes (including etching) are used throughout the process. If the thickness of the edge part of the cathode is small, it will be easily etched and damaged or even etched through when it encounters etching. This will not only lead to poor bonding between the cathode and the isolation structure, but may even damage the underlying film layer (such as the pixel boundary layer described below).

[0042] At least one embodiment of this disclosure provides a display panel to at least solve the aforementioned technical problems. The display panel includes a substrate, an isolation structure, and a plurality of light-emitting devices located on the substrate. Each light-emitting device includes a light-emitting area. The isolation structure defines a plurality of isolation openings, which limit the light-emitting devices. The centroid of the orthographic projection of the light-emitting area of ​​at least one light-emitting device onto the substrate is located outside the centroid of the orthographic projection of the corresponding isolation opening onto the substrate. The centroid mentioned in this disclosure refers to the center of a geometric shape. In some optional embodiments, a light-transmitting opening is also provided on the isolation structure. A certain distance is reserved between the light-emitting device and the light-transmitting opening to avoid partial structures of the light-emitting device (e.g., the first electrode described below) blocking the light-transmitting opening in the actual manufactured display panel. In this display panel, by offsetting the pixel opening, the light-emitting device can be offset to the side where the second electrode and the isolation structure are more easily joined (high-quality joining), further reducing the difficulty of joining the second electrode and the isolation structure on that side. This reduces the impedance between the second electrode and the isolation structure without increasing the thickness of the second electrode.

[0043] The structure of a display panel according to at least one embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings. Furthermore, in these drawings, a spatial Cartesian coordinate system is established with the substrate in the display panel as a reference to visually represent the positional relationships of the various components in the display panel. In this spatial Cartesian coordinate system, the X-axis and Y-axis are parallel to the plane of the substrate, and the Z-axis is perpendicular to the plane of the substrate.

[0044] As shown in Figures 1, 2, 3A, and 3B, the display panel 10 includes a display area 11 and a non-display area 12 surrounding the display area 11. The display area 11 contains sub-pixels that emit different colors of light, such as red sub-pixels R, green sub-pixels G, and blue sub-pixels B. It should be noted that in some embodiments of this disclosure, some traces in the non-display area 12 can be routed into the display area 11, thereby allowing the non-display area 12 to be designed as a single-sided bezel.

[0045] For example, the physical structure of the display panel 10 includes a substrate 100 and an isolation structure 300, a pixel defining layer 400 and a plurality of light-emitting devices 200 located on the substrate 100. The light-emitting devices 200 are physical light-emitting structures of sub-pixels such as R, G and B.

[0046] The light-emitting device 200 includes a first electrode 210, a light-emitting functional layer 230, and a second electrode 220 sequentially stacked on a substrate 100. The isolation structure 300 includes a plurality of isolation openings 301. The pixel defining layer 400 includes a pixel opening 401 communicating with the isolation openings 301. The light-emitting functional layer 230 and the second electrode 220 of the light-emitting device 200 are confined in the isolation openings 301 and the pixel openings 401. At at least one pixel opening 401 and isolation opening 301 where a light-emitting device 200 is located, there are at least two orthographic projections on the substrate 100 at the edge of the pixel opening 401. The distances to the orthographic projections on the substrate 100 of the edge of the isolation opening 301 are different. That is, the centroid of the pixel opening 401 is offset relative to the centroid of the isolation opening 301. Here, centroid offset means that the centroid of the orthographic projection of the pixel opening 401 on the substrate 100 is located outside the centroid of the orthographic projection of the isolation opening 301 on the substrate 100. In other words, the centroid of the orthographic projection of the pixel opening 401 on the substrate 100 does not overlap with the centroid of the orthographic projection of the isolation opening 301 on the substrate 100. Specifically, as shown in FIG3C, the centroid Q1 of the pixel opening 401 is offset relative to the centroid Q1 of the isolation opening 301. Thus, by offsetting the pixel opening 401, the light-emitting device 200 can be shifted to the side where the second electrode 220 and the isolation structure 300 are more easily connected, thereby further reducing the difficulty of connecting the second electrode 220 and the isolation structure 300 on that side and reducing the impedance between the second electrode 220 and the isolation structure 300. In addition, on the offset side (the side where the pixel opening 401 is closer to the isolation structure 300), the thickness of the edge portion of the second electrode 220 is relatively large, so that in the process of fabricating the light-emitting device 200 (fabricating subsequent batches of light-emitting devices 200), there is sufficient etching resistance, thereby not only ensuring the connection with the isolation structure, but also protecting the underlying pixel defining layer 400. In this disclosure, the distance from the orthographic projection of a certain position on the substrate to the orthographic projection of a certain edge on the substrate refers to the minimum distance from the orthographic projection of that position on the substrate to the orthographic projection of that edge on the substrate. For example, the distance from the orthographic projection of a certain position of the edge of the pixel opening on the substrate to the orthographic projection of the edge of the isolation opening on the substrate refers to the minimum distance from the orthographic projection of a certain position of the edge of the pixel opening on the substrate to the orthographic projection of the edge of the isolation opening on the substrate.

[0047] In at least one embodiment of this disclosure, as shown in FIG2, FIG3A and FIG3B, at the pixel opening 401 and the isolation opening 301 where at least one light-emitting device 200 is located, the orthographic projection of the edge of the isolation opening 301 on the substrate 100 has multiple isolation opening projection edges. The distance from the centroid Q1 of the orthographic projection of the pixel opening 401 on the substrate 100 to some of the isolation opening projection edges (e.g., the right side of the isolation opening 301 shown in FIG3C) is less than the distance from the centroid Q1 of the orthographic projection of the pixel opening 401 on the substrate 100 to other isolation opening projection edges (e.g., the left side of the isolation opening 301 shown in FIG3C). Thus, by offsetting the pixel opening 401, the light-emitting device 200 is brought closer to one side of the isolation structure 300, thereby allowing the second electrode 220 of the light-emitting device 200 to connect better with the isolation structure 300 on that side. For example, on that side, the pixel opening 401 is closer to the isolation structure 300, so the thickness of the portion where the second electrode 220 connects to the isolation structure 300 is greater, thereby reducing the impedance between the second electrode 220 and the isolation structure 300.

[0048] For example, in one example, as shown in FIG3B, there is only one isolation opening projection edge that is the closest to the centroid Q1 of the orthographic projection of the pixel opening 401 on the substrate 100. That is, the pixel opening 401 is offset only in the direction of one edge of the isolation opening 301 (e.g., to the right in FIG3B).

[0049] For example, in another example, as shown in FIG3C, the minimum distance to the centroid Q1 of the orthographic projection of the pixel opening 401 on the substrate 100 is at least two isolation opening projection edges, that is, the pixel opening 401 is offset in the direction of at least two edges of the isolation opening 301 (e.g., the upper right in FIG3B). For example, further, the minimum distance to the centroid Q1 of the orthographic projection of the pixel opening 401 on the substrate 100 is at least two isolated opening projection edges connected, that is, the pixel opening 401 is offset in the direction of at least one corner of the isolation opening 301 (e.g., the upper right corner of the isolation opening 301 in FIG3B).

[0050] In at least one embodiment of this disclosure, as shown in FIG3B, the orthographic projection of the pixel opening 401 on the substrate 100 includes a first pixel opening projection edge 401a and a second pixel opening projection edge 401b that are opposite to each other. It should be noted that the orthographic projection of the pixel opening 401 on the substrate 100 refers to the orthographic projection of the area enclosed by the sidewall of the pixel opening 401 near the first electrode 210 on the substrate 100. The distance d1 from the first pixel opening projection edge 401a to the edge of the isolation opening 301 on the substrate 100 is less than the distance d2 from the second pixel opening projection edge 401b to the edge of the isolation opening 301 on the substrate 100. Thus, on the side where the first pixel opening projection edge 401a is located, the width of the portion of the second electrode 220 extending onto the pixel defining layer 400 is small. This allows for a larger deposition thickness of the second electrode 220 on the pixel defining layer 400 on that side during the formation process (e.g., vapor deposition), and makes it easier for the second electrode 220 to climb onto the sidewall of the isolation structure 300. In other words, the thickness and area of ​​the portion of the second electrode 220 in contact with the isolation structure 300 are larger, thereby reducing the impedance of the second electrode 220 and the isolation structure 300 on the side where the first pixel opening projection edge 401a is located. In some embodiments, the orthographic projection of the edge of the isolation opening 301 onto the substrate 100 includes a straight edge. The orthographic projections of the first pixel opening projection edge 401a and the edge of the isolation opening 301 onto the substrate 100 are both straight edges and parallel. The orthographic projections of the second pixel opening projection edge 401b and the edge of the isolation opening 301 onto the substrate 100 are both straight edges and parallel. The first pixel opening projection edge 401a and the second pixel opening projection edge 401b are parallel.

[0051] In at least one embodiment of this disclosure, as shown in FIG3D, the orthographic projection of the pixel opening 401 on the substrate 100 includes a third pixel opening projection edge 401c and a fourth pixel opening projection edge 401d. The length of the third pixel opening projection edge 401c is greater than the length of the fourth pixel opening projection edge 401d. The distance d3 from the third pixel opening projection edge 401c to the orthographic projection d3 of the edge of the isolation opening 301 on the substrate 100 is less than the distance d4 from the fourth pixel opening projection edge 401d to the orthographic projection d4 of the edge of the isolation opening 301 on the substrate 100. Thus, at the location of the side with the larger length of the pixel opening 401 (the fourth pixel opening projection edge 401d), the contact area (including the length of the contact boundary) between the second electrode 220 and the isolation structure 300 is larger. When the pixel opening 401 is offset towards the side with the larger length (the fourth pixel opening projection edge 401d), the impedance between the second electrode 220 and the isolation structure 300 can be further reduced.

[0052] In at least one embodiment of this disclosure, as shown in Figures 3A and 3B, the first pixel opening projection edge 401a corresponds to the first side of the isolation opening 301 (e.g., the right side in the figure), the second pixel opening projection edge 401b corresponds to the second side of the isolation opening 301 (e.g., the left side in the figure), the second electrode 220 overlaps with the isolation structure 300, and the distance from the end of the second electrode 220 away from the substrate 100 to the substrate 100 of the portion of the second electrode 220 overlapping with the isolation structure 300 on the first side is greater than the distance from the end of the second electrode 220 away from the substrate 100 to the substrate 100 of the portion of the second electrode 220 overlapping with the isolation structure 300 on the second side, that is, relative to the second side, the climbing height of the edge of the second electrode 220 on the sidewall of the isolation structure 300 is higher on the first side; and / or, the thickness of the second electrode 220 overlapping with the isolation structure 300 on the first side is greater than the thickness of the second electrode 220 overlapping with the isolation structure 300 on the second side.

[0053] During the deposition of the second electrode 220 based on the isolation structure 300, due to the shielding effect of the isolation structure 300, the closer to the isolation structure 300, the less material is deposited. Therefore, the thickness at the edge of the second electrode 220 will become smaller and smaller. Assuming that without offset, the edge of the second electrode 220 begins to contact the isolation structure 300 at a first preset thickness, after offsetting the pixel opening 401, on the side where the first pixel opening projection edge 401a is located, because the distance between the edge of the pixel opening 401 and the edge of the isolation opening 301 is reduced, the edge of the second electrode 220 begins to contact the isolation structure 300 when it is greater than the first preset thickness. This increases the thickness (e.g., the average thickness of the film) of the portion of the second electrode 220 located between the pixel opening 401 and the isolation structure 300, and increases the climbing height of the second electrode 220 on the isolation structure 300 (increases the contact area and the thickness of the contact portion), thereby reducing the impedance between the second electrode 220 and the isolation structure 300.

[0054] In at least one embodiment of this disclosure, as shown in Figures 4A to 4C, the light-emitting devices 200 are classified into a first type of light-emitting device 200a, a second type of light-emitting device 200b, and a third type of light-emitting device 200c with different light-emitting colors. The first type of light-emitting device 200a, the second type of light-emitting device 200b, and the third type of light-emitting device 200c are arranged in multiple rows and columns. The first type of light-emitting device 200a and the third type of light-emitting device 200c are arranged in the same row and in the same column. The first type of light-emitting device 200a and the third type of light-emitting device 200c are arranged alternately in the same column and in the same row. The column containing the first type of light-emitting device 200a and the third type of light-emitting device 200c alternates with the column containing the second type of light-emitting device 200b. The row containing the first type of light-emitting device 200a and the third type of light-emitting device 200c alternates with the row containing the second type of light-emitting device 200b. With this pixel arrangement, it is easy to offset the pixel opening 401 corresponding to the light-emitting device 200, and while ensuring a high pixel density (PPI), the impedance between the second electrode 220 and the isolation structure 300 in the entire display panel is further reduced.

[0055] For example, as shown in FIG4B, at least one light-emitting device 200 has a pixel opening 401 that is hexagonal, and each includes two opposing first straight sides 401Z1, two opposing first inclined sides 401X1, and two opposing second inclined sides 401X2. The first straight side 401Z1 is located between the first inclined sides 401X1 and the second inclined sides 401X2. The distance from the orthographic projection of one first straight side 401Z1 (e.g., the right side of the pixel opening 401 in FIG4B) onto the substrate 100 to the orthographic projection of the edge of the isolation opening 301 onto the substrate 100 is less than the distance from the orthographic projection of the other first straight side 401Z1 (e.g., the left side of the pixel opening 401 in FIG4B) onto the substrate 100 to the orthographic projection of the edge of the isolation opening 301 onto the substrate 100. For example, the first straight side 401Z1 is parallel to the column direction, the first hypotenuse 401X1 and the second hypotenuse 401X2 intersect the column and row directions but are not perpendicular, and the area of ​​the first type of light-emitting device 200a is smaller than the area of ​​the third type of light-emitting device 200c in the pixel opening 401 corresponding to the first type of light-emitting device 200a and the third type of light-emitting device 200c.

[0056] For example, as shown in Figure 4B, when the light-emitting devices 200 are classified into a first type of light-emitting device 200a, a second type of light-emitting device 200b, and a third type of light-emitting device 200c with different light-emitting colors, the pixel openings 401 that are hexagonal in orthographic projection on the substrate 100 are the pixel openings 401 corresponding to the first type of light-emitting device 200a and the pixel openings 401 corresponding to the third type of light-emitting device 200c.

[0057] As shown in Figure 4C, the pixel opening 401 corresponding to the second type of light-emitting device 200b includes two opposing second straight edges 401Z2, two opposing third oblique edges 401X3, and two opposing arcuate edges 401H. The second straight edges 401Z2 are located between the third oblique edges 401X3 and the arcuate edges 401H. In the pixel opening 401 corresponding to the second type of light-emitting device 200b, the distance from the orthographic projection of one second straight edge 401Z2 (e.g., the right side of the pixel opening 401 in Figure 4C) onto the substrate 100 to the orthographic projection of the edge of the isolation opening 301 onto the substrate 100 is smaller than the distance from the orthographic projection of the other second straight edge 401Z2 (e.g., the left side of the pixel opening 401 in Figure 4C) onto the substrate 100 to the orthographic projection of the edge of the isolation opening 301 onto the substrate 100. The first straight edge 401Z1 and the second straight edge 401Z2 can be parallel or perpendicular to the scan signal line. For example, the second straight side 401Z2 is parallel to the column direction, and the third hypotenuse 401X3 intersects the column and row directions but is not perpendicular to them.

[0058] In the embodiments shown in Figures 4A to 4C, the arrangement and shape of the first type of light-emitting device 200a, the second type of light-emitting device 200b, and the third type of light-emitting device 200c can facilitate the offset of the pixel openings 401 corresponding to each light-emitting device 200 to the same side or opposite side, thereby simplifying the manufacturing process of the display panel and making it easier to control the manufacturing process cost of the display panel.

[0059] In at least one embodiment of this disclosure, as shown in Figures 4A to 4C, the first straight edge 401Z1 and the second straight edge 401Z2 are parallel, for example, both are parallel to the Y-axis direction. This simplifies the manufacturing process of the display panel and makes it easier to control the manufacturing cost of the display panel.

[0060] In the embodiments of this disclosure, after the pixel aperture is offset relative to the isolation aperture, the offset amount can be controlled so that the second electrode still overlaps with both sides of the isolation structure in the offset direction (the closer side has a higher degree of overlap and lower impedance); or, the offset amount can be increased so that the second electrode overlaps with only one side of the isolation structure in the offset direction, thereby achieving better overlap quality between the second electrode and the isolation structure on the overlap side, further reducing the impedance between the second electrode and the isolation structure. The two cases will be described below with reference to different accompanying drawings.

[0061] For example, in one instance, referring again to Figures 3A and 3B, the second electrode 220 is connected to the isolation structure 300 on both sides where the first pixel opening projection edge 401a and the second pixel opening projection edge 401b are located.

[0062] [Correction 09.01.2026 according to Rule 91] For example, in another example, as shown in FIG5, the first pixel opening projection edge 401a corresponds to the first side of the isolation opening 301, the second pixel opening projection edge 401b corresponds to the second side of the isolation opening 301, the second electrode 220 overlaps with the isolation structure 300 on the first side, and there is a gap between the second electrode 220 and the isolation structure 300 on the second side.

[0063] During the fabrication of the light-emitting device 200, if the second electrode 220 and the isolation structure 300 have good overlap on both sides where the first pixel opening projection edge 401a and the second pixel opening projection edge 401b are located, two vapor deposition processes (corresponding to two different vapor deposition angles) are required to form the second electrode 220. Thus, if the edge of the second electrode 220 has sufficient thickness on both sides to reduce the impedance between it and the isolation structure 300, the second electrode 220 (e.g., the area in the middle used for light transmission) will have a large overall thickness, thereby reducing the light transmittance, which will reduce the light emission rate of the display panel. Alternatively, if the second electrode 220 (e.g., the area in the middle used for light transmission) has a small overall thickness to ensure light transmission, the thickness of the edge of the second electrode 220 on both sides (e.g., the first thickness) will be limited, making it difficult to reduce the impedance between it and the isolation structure 300, or even leading to poor contact. In the scheme shown in Figure 5, the second electrode 220 does not need to overlap with the isolation structure 300 on the second side. Therefore, during the vapor deposition process of the second electrode 220, only one vapor deposition process can be performed. This ensures that the thickness of the middle region of the second electrode 220 is small to achieve high light transmittance, while also ensuring that the edge of the second electrode 220 on the first side has sufficient thickness (a second thickness, for example, twice the first thickness) to reduce the impedance between it and the isolation structure 300.

[0064] In the embodiments of this disclosure, the horizontal spacing between the edges of the pixel opening 401 and the isolation opening 301 can be set according to specific requirements, and the embodiments of this disclosure do not limit this.

[0065] For example, in at least one embodiment of this disclosure, referring again to FIG3A, the distance D between the orthographic projection of the edge of the pixel opening 401 on the substrate 100 and the orthographic projection of the edge of the isolation opening 301 on the substrate 100 is 0.3 micrometers to 10 micrometers, for example, it can be 0.3 micrometers, 0.5 micrometers, 1 micrometer, 3 micrometers, 5 micrometers, 7 micrometers, 9 micrometers, 9.5 micrometers, 10 micrometers, etc.

[0066] For example, in at least one embodiment of this disclosure, as shown in FIG5, on the first side (the side where the first pixel opening projection edge 401a is located), the distance D1 between the orthographic projection of the edge of the pixel opening 401 on the substrate 100 and the orthographic projection of the edge of the isolation opening 301 on the substrate 100 can be 0.3 micrometers to 6 micrometers, for example, it can be 0.3 micrometers, 0.5 micrometers, 1 micrometer, 3 micrometers, 5 micrometers, 5.5 micrometers, etc.

[0067] For example, in at least one embodiment of this disclosure, as shown in FIG5, on the second side (the side where the second pixel opening projection edge 401b is located), the distance D2 between the orthographic projection of the edge of the pixel opening 401 on the substrate 100 and the orthographic projection of the edge of the isolation opening 301 on the substrate 100 can be 0.6 micrometers to 10 micrometers, for example, it can be 0.6 micrometers, 0.8 micrometers, 1.5 micrometers, 3.5 micrometers, 5.5 micrometers, 7.5 micrometers, 9.5 micrometers, 10 micrometers, etc.

[0068] In at least one embodiment of this disclosure, referring again to Figures 3A and 3B, the first pixel opening projection edge 401a corresponds to the first side of the isolation opening 301, and the orthographic projection of the first side of the isolation opening 301 onto the substrate 100 is a straight edge. Thus, the pixel opening 401 is offset towards the side containing the straight edge of the isolation opening 301, thereby further increasing the connection area between the second electrode 220 and the isolation structure 300, and further reducing the impedance between the second electrode 220 and the isolation structure 300.

[0069] In at least one embodiment of this disclosure, referring again to Figures 1, 2, 3A, and 3B, the substrate 100 may further include scanning signal lines, and the orthographic projection of the first side of the isolation opening 301 onto the substrate 100 is parallel or perpendicular to the scanning signal lines (the perpendicular case is shown in Figure 1). Thus, when the second electrode 220 is formed in the vapor deposition process, the scanning direction of the nozzle of the vapor deposition source is perpendicular to the straight edge (the edge of the first side) of the isolation opening, thereby improving the overlap between the second electrode 220 and the isolation structure 300. Furthermore, when the scanning signal lines are arranged in the display panel, their extension direction is perpendicular or parallel to the scanning direction of the nozzle.

[0070] In the embodiments of this disclosure, it is possible to offset all pixel openings or to offset only some pixel openings, depending on actual needs. The corresponding structures of the display panel are described below in the embodiments for each of these options.

[0071] In some embodiments of this disclosure, referring again to FIG2, the light-emitting devices 200 are classified into light-emitting devices with different emitting colors, such as first-type light-emitting devices 200a, second-type light-emitting devices 200b, and third-type light-emitting devices 200c. At the pixel openings 401 and isolation openings 301 where all light-emitting devices 200 of different emitting colors are located, at least two positions on the edge of the pixel opening 401 have orthographic projections onto the substrate 100, and the distances to the orthographic projections of the edge of the isolation opening 301 onto the substrate 100 are different. Thus, the pixel openings 401 corresponding to all light-emitting devices 200 are offset to reduce the impedance between all the second electrodes 220 and the isolation structure 300 in the display panel.

[0072] In other embodiments of this disclosure, as shown in FIG6, the light-emitting devices 200 are classified into light-emitting devices with different light-emitting colors, such as first-type light-emitting devices 200a, second-type light-emitting devices 200b, and third-type light-emitting devices 200c. At pixel openings 401 and isolation openings 301, there are at least two orthogonal projections on the substrate 100 at the edge of pixel opening 401, with different distances to the orthogonal projections on the substrate 100 of the edge of isolation opening 301. Furthermore, at pixel openings 401 and isolation openings 301, there are at least two other light-emitting devices 200 (e.g., first-type light-emitting devices 200a), with at least two orthogonal projections on the substrate 101 at the edge of pixel opening 401, with the same distance to the orthogonal projections on the substrate 101 of the edge of isolation opening 301. In this way, only the pixel openings 401 corresponding to some of the light-emitting devices 200 are offset, so the impedance between the second electrode 220 and the isolation structure 300 in a specific type of light-emitting device 200 can be adjusted according to the pixel arrangement and other requirements.

[0073] It should be noted that in the embodiments of this disclosure, the aforementioned "same distance" refers to the theoretical (ideal state during structural design) equality. However, in actual manufacturing processes, due to factors such as process errors, there may actually be an absolute error between two "same distance" comparison objects. For example, this absolute error can be less than 1 micrometer. That is, when it is less than 1 micrometer, the comparison objects are still considered to be "same distance". It should be noted that this situation is only valid if the two comparison objects are theoretically designed to be strictly equal in distance when designing the structure of the display panel. When the two comparison objects (e.g., the centroids corresponding to the isolation opening 301 and the pixel opening 401) have an "unequal" relationship from the beginning of the design (e.g., unequal distances from a certain reference object, i.e., there is an offset between them), even if the range of "unequal" is less than 1 micrometer, the two are still considered to be "unequal".

[0074] In at least one embodiment of this disclosure, as shown in FIG6, the light-emitting devices 200 are classified into light-emitting devices 200 with different light-emitting colors, such as a first type of light-emitting device 200a, a second type of light-emitting device 200b, and a third type of light-emitting device 200c. The pixel openings 401 corresponding to at least two types of light-emitting devices 200 (e.g., the second type of light-emitting device 200b and the third type of light-emitting device 200c) include a first pixel opening projection edge 401a and a second pixel opening projection edge 401b, that is, the pixel openings 301 corresponding to some of the light-emitting devices 200 with certain light-emitting colors are offset. For example, in FIG6, the pixel openings 301 corresponding to the second type of light-emitting device 200b and the third type of light-emitting device 200c are offset, while the pixel opening 301 corresponding to the first type of light-emitting device 200a is not offset.

[0075] In one example, as shown in Figure 6, for light-emitting devices 200 (e.g., second-type light-emitting device 200b and third-type light-emitting device 200c) corresponding to pixel openings 401 including the first pixel opening projection edge 401a and the second pixel opening projection edge 401b, the direction from the first pixel opening projection edge 401a to the second pixel opening projection edge 401b is the same for the pixel openings 200 with different emitted colors. That is, the offset direction of the pixel openings 401 relative to the isolation opening 301 is the same (in Figure 6, they are all offset to the right, i.e., in the positive X-axis direction). In this way, the offset direction of the pixel openings 401 corresponding to all light-emitting devices 200 is the same, which can reduce the difficulty of the display panel manufacturing process and reduce the manufacturing cost of the display panel.

[0076] For example, in another example, as shown in FIG7, for light-emitting devices 200 (e.g., second-type light-emitting device 200b and third-type light-emitting device 200c) corresponding to pixel openings 401 including first pixel opening projection edge 401a and second pixel opening projection edge 401b, the directions from the first pixel opening projection edge 401a to the second pixel opening projection edge 401b are different. For example, the pixel opening 401 corresponding to the second-type light-emitting device 200b has the same offset direction relative to the isolation opening 301 (in FIG7, it is offset to the left, i.e., the negative X-axis direction), and the pixel opening 401 corresponding to the third-type light-emitting device 200c has the same offset direction relative to the isolation opening 301 (in FIG7, it is offset to the right, i.e., the positive X-axis direction). Different types of light-emitting devices 200 are prepared in batches, and the shapes and arrangements of different types of light-emitting devices 200 may be different. In this technical solution, the offset direction of the pixel opening 401 corresponding to each type of light-emitting device 200 can be set according to actual needs, so as to reduce the impedance between the second electrode 220 of each type of light-emitting device 200 and the isolation structure 300.

[0077] In the embodiments of this disclosure, the degree of offset (the magnitude of the offset) of the pixel openings corresponding to different light-emitting devices is not limited, and can be designed according to actual needs. Below, the corresponding structures of the display panel are described in the following embodiments for several of these options.

[0078] For example, in one instance, as shown in Figures 2 and 8, for light-emitting devices 200 corresponding to pixel openings 401 including first pixel opening projection edge 401a and second pixel opening projection edge 401b, the distance T1 from the centroid Q2 of the orthogonal projection of the first pixel opening projection edge 401a to the centroid Q2 of the orthogonal projection of the isolation opening 301 on the substrate 100 to the second pixel opening projection edge 401b to the centroid Q2 of the orthogonal projection of the isolation opening 301 on the substrate 100 is equal to the distance T2 of the same distance. Thus, the degree of offset of the pixel openings 401 corresponding to all light-emitting devices 200 is the same, thereby reducing the manufacturing difficulty of the display panel and lowering its manufacturing cost.

[0079] It should be noted that in the embodiments of this disclosure, the above-mentioned "equal difference" is the same in theory (ideal state during structural design). However, in actual process, due to factors such as process error, there may be an absolute error between two "equal difference" comparison objects. For example, the absolute error can be less than 1 micrometer. That is, when it is less than 1 micrometer, the relationship between the comparison objects is still considered to be "equal difference".

[0080] For example, in another example, as shown in Figures 7 and 8, for the light-emitting device 200 corresponding to the pixel opening 401 including the first pixel opening projection edge 401a and the second pixel opening projection edge 401b, the distance T1 from the first pixel opening projection edge 401a to the centroid Q2 of the orthogonal projection of the isolation opening 301 on the substrate 100 is not equal to the distance T2 from the second pixel opening projection edge 401b to the centroid Q2 of the orthogonal projection of the isolation opening 301 on the substrate 100. For example, for the pixel openings 401 corresponding to the second type of light-emitting device 200b and the third type of light-emitting device 200c, the difference between the distance T1 and the distance T2 at the pixel opening 401 corresponding to the third type of light-emitting device 200c is larger (the degree of offset is greater). Different types of light-emitting devices 200 are fabricated in batches, and the shapes and arrangements of different types of light-emitting devices 200 may be different. In this technical solution, the offset of the pixel opening 401 corresponding to each type of light-emitting device 200 can be designed according to actual needs, so as to reduce the impedance between the second electrode 220 of each type of light-emitting device 200 and the isolation structure 300.

[0081] Below, in the embodiments of this disclosure, the specific design of the isolation structure and the principle of its isolation of the film layer of the light-emitting device will be described with reference to the accompanying drawings.

[0082] In at least one embodiment of this disclosure, referring again to FIG3A, the light-emitting device 200 includes a first electrode 210, a second electrode 220, and a light-emitting functional layer 230 sequentially stacked on a substrate 100, wherein the light-emitting functional layer 230 and the second electrode 220 are located in corresponding isolation openings 301. For example, the first electrode 210 may be configured as an anode, and the second electrode 220 may be configured as a cathode.

[0083] For example, the light-emitting functional layer 230 may include a first common layer 231, a light-emitting layer 232, and a second common layer 233, which are sequentially stacked on the first electrode 210. The first common layer 231 may include a hole injection layer, a hole transport layer, an electron blocking layer, etc. The second common layer 232 may include an electron injection layer, an electron transport layer, a hole blocking layer, etc. The isolation structure 300 needs to ensure that the first common layer 231 (the main film layer causing current crosstalk) of each light-emitting device 200 is electrically disconnected from each other.

[0084] In at least one embodiment of this disclosure, referring again to FIG. 3A, the isolation structure 300 includes a support portion 310 and a crown portion 320. The support portion 310 is located between the crown portion 320 and the substrate 100. The orthographic projection of the end of the support portion 310 facing the crown portion 320 on the substrate 100 lies within the orthographic projection of the crown portion 320 on the substrate 100. Thus, when depositing film layers (e.g., light-emitting functional layer 230 and second electrode 220) in the light-emitting device 200, the crown portion 320 can limit the deposition range of these film layers, so that while some film layers (e.g., light-emitting functional layer 230) are isolated by the isolation structure 300, other film layers (e.g., second electrode 220) are still connected to the isolation structure 300.

[0085] For example, the orthographic projection of the support portion 310 onto the substrate 100 lies within the orthographic projection of the crown portion 320 onto the substrate 100. Thus, the cross-sectional shape of the portion of the isolation structure 300 located between adjacent isolation openings 301 is approximately an inverted trapezoid, thereby increasing the isolation effect of the isolation structure 300 on the film layers of the light-emitting device 200. Specifically, when depositing film layers (e.g., the light-emitting functional layer 230 and the second electrode 220) in the light-emitting device, the crown portion 320 can limit the deposition range of these film layers, ensuring that while some film layers (e.g., the light-emitting functional layer) are isolated by the isolation structure 300, other film layers (e.g., the second electrode 220) remain connected to the isolation structure 300.

[0086] For example, the isolation structure 300 is located on the side of the pixel defining layer 400 away from the substrate 100, so that the pixel defining layer 400 can cover the gaps between each of the first electrodes 210 and can cover the edges of the first electrodes 210 to prevent the isolation structure 300 from being connected to the first electrodes 210.

[0087] In at least one embodiment of this disclosure, referring again to FIG3A, the support portion 310 is a conductive structure, and the second electrode 222 is connected to the side surface of the support portion 310. Thus, the second electrodes 220 of each light-emitting device 200 are connected together through the support portion 310 to form a common electrode, and the support portion 310 is not limited by thickness, thereby reducing the impedance of the common electrode.

[0088] It should be noted that the material of the second electrode 220 can be a metallic material. The smaller the thickness of the second electrode 220, the higher its light transmittance, but its resistivity is also higher. If the thickness of the second electrode 220 is too small, without the isolation structure 300, the voltage drop of the second electrode 220 (which is the common electrode at this time) will be too large. In the embodiments of this disclosure, the second electrode 220 is connected to the conductive support portion 310, which can remove the thickness limitation of the second electrode 220, thereby allowing the second electrode 220 to have a smaller thickness and higher light transmittance.

[0089] For example, the pixel opening 401 of the pixel defining layer 400 limits the light-emitting device 220 and exposes the first electrode 210. That is, the edge of the pixel opening 401 coincides with the edge of the light-emitting area of ​​the corresponding light-emitting device 220. The pixel opening 401 corresponds one-to-one with the isolation opening 301, and the pixel opening 401 is connected to the corresponding isolation opening 301.

[0090] It should be noted that in the embodiments of this disclosure, the above-mentioned "overlap" is the same in theory (ideal state during structural design). However, in actual process, due to factors such as process error, there may be an absolute error between two "overlapping" comparison objects. For example, the absolute error can be less than 1 micrometer. That is, when it is less than 1 micrometer, the relationship between the comparison objects is still considered to be "overlapping".

[0091] For example, the pixel defining layer 400 can be an inorganic film layer. In the process of fabricating the light-emitting device 220 based on the isolation structure 300, the pixel defining layer 400 does not need to be thick enough to accommodate the light-emitting device 220, which is beneficial for the thinner and lighter design of the display panel. In addition, as an inorganic film layer, the pixel defining layer 400 can have a high bonding strength with the isolation structure 300 and the first electrode 210, thereby reducing the risk of the isolation structure 300 and the first electrode 210 falling off. Furthermore, the high density of the inorganic film layer can more effectively block the intrusion of water, oxygen, etc., thereby improving the encapsulation effect of the display panel. Moreover, when the pixel defining layer 400 is an inorganic layer, it can have a smaller thickness, thereby reducing the discontinuity at the edge of the pixel opening 401, improving the film continuity of the second electrode 220 at that location, reducing the impedance of the second electrode 220, and thus ensuring the display effect of the display panel.

[0092] For example, the pixel defining layer 400 can be an inorganic film layer. In the process of fabricating the light-emitting device 220 based on the isolation structure 300, the pixel defining layer 400 does not need to be very thick to accommodate the light-emitting device 220, which is beneficial for the thinner and lighter design of the display panel. In addition, as an inorganic film layer, the pixel defining layer 400 can have a high bonding strength with the isolation structure 300 and the first electrode 210, thereby reducing the risk of the isolation structure 300 and the first electrode 210 falling off. Furthermore, the high density of the inorganic film layer can more effectively block the intrusion of water, oxygen, etc., thereby improving the encapsulation effect of the display panel. Moreover, when the pixel defining layer 400 is an inorganic layer, it can have a smaller thickness, thereby reducing the discontinuity at the edge of the pixel opening 401, improving the film continuity of the second electrode 220 at that location, reducing the impedance of the second electrode 220, and thus ensuring the display effect of the display panel.

[0093] In at least one embodiment of this disclosure, as shown in FIG9, the isolation structure 300 further includes a bottom 330. The bottom 330 is located on the side of the support portion 310 opposite to the crown portion 320 and is a conductive structure. The orthographic projection of the bottom 330 on the substrate 100 lies within the orthographic projection of the crown portion 320 on the substrate 100, and the orthographic projection of the support portion 310 on the substrate 100 lies within the orthographic projection of the bottom 330 on the substrate 100. The second electrode 220 is connected to the area of ​​the bottom 330 on the surface opposite to the substrate 100 that is not covered by the support portion 310. Corresponding to the side surface of the support portion 310, the second electrode 220 is more easily deposited on the bottom 330, thereby reducing the impedance at the connection between the second electrode 220 and the isolation structure 300.

[0094] For example, the crown 320, the support 310 and the bottom 330 can be made of titanium, aluminum and molybdenum in sequence to form the isolation structure 300 as shown in Figure 9.

[0095] It should be noted that, in the embodiments of this disclosure, there is no limitation on whether the first electrode 210 is offset relative to the isolation opening 301 and / or the pixel opening 302, and it can be designed according to actual process requirements. Below, different embodiments are used to exemplarily illustrate the arrangement of the first electrode 210 in these cases.

[0096] For example, in some embodiments of this disclosure, as shown in FIG10, the centroid of the orthogonal projection of the first electrode 210 on the substrate 100 may not be offset relative to the centroid of the orthogonal projection of the isolation opening 301 on the substrate 100, but may be offset relative to the centroid of the orthogonal projection of the pixel opening 401 on the substrate 100. For example, at least one centroid of the orthogonal projection of the first electrode 210 on the substrate 100 coincides with the centroid of the orthogonal projection of the isolation opening 301 on the substrate 100, and is located outside the centroid of the orthogonal projection of the pixel opening 401 on the substrate 100.

[0097] For example, in other embodiments of this disclosure, referring again to FIG3A or FIG9, the centroid of the orthogonal projection of the first electrode 210 on the substrate 100 may be offset relative to the centroid of the orthogonal projection of the isolation opening 301 on the substrate 100, but not offset relative to the centroid of the orthogonal projection of the pixel opening 401 on the substrate 100. For example, at least one centroid of the orthogonal projection of the first electrode 210 on the substrate 100 is located outside the centroid of the orthogonal projection of the isolation opening 301 on the substrate 100, and coincides with the centroid of the orthogonal projection of the pixel opening 401 on the substrate 100. In this way, the alignment of the first electrode 210 and the pixel opening 401 can be ensured, so that the pixel opening 401 falls completely on the first electrode 210, thereby ensuring the area of ​​the actual light-emitting region of the light-emitting device 200.

[0098] For example, in other embodiments of this disclosure, the first electrode 210 may not be offset relative to the isolation opening 301 and may be offset relative to the pixel opening 401 (not shown in the figures). For example, the centroid of the orthogonal projection of at least one first electrode 210 onto the substrate 100 is located outside the centroid of the orthogonal projection of the isolation opening 301 onto the substrate 100, and is also located outside the centroid of the orthogonal projection of the pixel opening 401 onto the substrate 100.

[0099] It should be noted that, in the embodiments of this disclosure, there is no limitation on whether the second electrode 220 is offset relative to the isolation opening 301 and / or the pixel opening 302, and it can be designed according to actual process requirements. Below, different embodiments are used to exemplarily illustrate the arrangement of the first electrode 210 in these cases.

[0100] For example, in some embodiments of this disclosure, referring again to FIG3A, the centroid of at least one second electrode 220 coincides with the centroid of the isolation opening 301. The specific structure of the display panel in this case can be found in the foregoing description of the embodiments shown in FIG3A, and will not be repeated here.

[0101] For example, in some other embodiments of this disclosure, referring again to FIG5, the first pixel opening projection edge 401a corresponds to the first side of the isolation opening 301, the second pixel opening projection edge 401b corresponds to the second side of the isolation opening 301, the second electrode 220 overlaps with the isolation structure 300 on the first side, and there is a gap between the second side and the isolation structure 300, the centroid of the orthographic projection of the second electrode 220 on the substrate 100 is located between the centroid of the orthographic projection of the isolation opening 301 on the substrate 101 and the first pixel opening projection edge 401a. The specific structure of the display panel in this case can be found in the foregoing description of the embodiments shown in FIG5, and will not be repeated here. For example, further, the centroid of the orthographic projection of the pixel opening 401 on the substrate 100 is located between the centroid of the orthographic projection of the second electrode 220 on the substrate 100 and the projection edge 401a of the first pixel opening. That is, when the pixel opening 401 and the second electrode 220 are offset in the same direction relative to the isolation opening 301, the offset of the pixel opening 401 relative to the isolation opening 301 is greater than the offset of the second electrode 220 relative to the isolation opening 301.

[0102] In at least one embodiment of this disclosure, as shown in FIG10, the display panel may further include a first encapsulation layer 510. The first encapsulation layer 510 includes encapsulation units 511 that respectively cover the light-emitting devices 200. The centroid of the orthographic projection of the encapsulation unit 511 on the substrate 100 coincides with the centroid of the orthographic projection of the isolation opening 301 on the substrate 100. The light-emitting devices 200 are prepared in batches based on different emission colors, and the encapsulation units 511 are prepared in batches along with the light-emitting devices 200, thereby protecting the already formed light-emitting devices 200 throughout the entire manufacturing process.

[0103] It should be noted that during the fabrication of the light-emitting device, the packaging unit 511 is subject to etching, which may result in localized areas of the packaging unit 511 being etched through. In this case, the second electrode 220 resists etching. However, if the thickness of the second electrode 220 is small, there is a risk that the second electrode 220 may be etched through, potentially leading to further etching damage to the underlying pixel defining layer 400. By employing the technical solution in the embodiments of this disclosure, this technical problem can be solved. The specific structures and technical principles involved can be found in the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0104] In at least one embodiment of this disclosure, as shown in FIG10, the edge of the encapsulation unit 511 extends to the side of the crown 320 opposite to the substrate 100, and the portion of the encapsulation unit 511 located on the side of the crown 320 opposite to the substrate 100 is spaced from the crown 320 to form a suspended portion. The reason for the formation of the suspended portion is related to the process of fabricating the light-emitting device 200 based on the isolation structure 300.

[0105] In at least one embodiment of this disclosure, as shown in FIG11, the encapsulation structure 500 may further include a second encapsulation layer 520 and a third encapsulation layer 530 covering the first encapsulation layer 510 and the isolation structure 300, with the second encapsulation layer 520 located between the first encapsulation layer 510 and the third encapsulation layer 530. For example, the first encapsulation layer 510 and the third encapsulation layer 530 may be inorganic layers with high density to isolate water and oxygen, while the second encapsulation layer 520 may be an organic layer serving as a planarization layer, thereby having a larger thickness to planarize the surface of the display panel, so as to facilitate the fabrication of functional structures such as touch structures, optical films, and cover plates on the encapsulation structure 500.

[0106] In the embodiments of this disclosure, the pixel opening 401 is actually used to define the light-emitting area of ​​the light-emitting device 200. Therefore, the offset of the pixel opening 401 is actually equivalent to the offset of the light-emitting area of ​​the light-emitting device 200. It should be noted that the range of the light-emitting area of ​​the light-emitting device 200 is also related to the first electrode 210 of the light-emitting device 200. The area where the first electrode 210 overlaps with the pixel opening 401 is the light-emitting area of ​​the light-emitting device 200. Therefore, whether the first electrode 210 is offset and the degree of offset will affect the degree of overlap between the first electrode 210 and the pixel opening 401, thereby determining whether the light-emitting area of ​​the light-emitting device 200 is offset and the degree of offset.

[0107] The specific structure of the display panel will be further described below from the perspective of the positional relationship between the first electrode 210, the isolation opening 301, and the pixel opening 401.

[0108] In at least one embodiment of this disclosure, referring again to FIG3A, at at least one isolation opening 301, the centroid of the orthographic projection of the gap between adjacent first electrodes 210 onto the substrate 100 (covered by the isolation structure 300) is located outside the centroid of the orthographic projection of the isolation opening 301 onto the substrate 100. Thus, the first electrodes 210 can be offset along with the pixel opening 401 (the offset direction and size can be the same or different) to adjust the distribution of the portion of the pixel defining layer 400 covering the edge of the first electrodes 210 (which will be raised by the first electrodes 210), thereby adjusting the impedance at different connection points between the second electrode 220 and the isolation structure 300.

[0109] In at least one embodiment of this disclosure, referring again to FIG5, the centroid of the orthographic projection of the portion of the isolation structure 300 located between two adjacent isolation openings 301 on the substrate 100 is located outside the centroid of the orthographic projection of the gap between the first electrodes 210 corresponding to the two adjacent isolation openings 301 on the substrate 100. For example, in this case, the centroid of the orthographic projection of the first electrode 210 on the substrate 100 is located outside the centroid of the orthographic projection of the isolation opening 301 on the substrate 100, that is, the first electrode 210 is offset relative to the isolation opening 301. In this way, while ensuring that the first electrode 210 is offset relative to the isolation opening 301, it is not necessary to change the settings of the parameters of the isolation structure 300 itself (such as the width between adjacent isolation openings 301), so as to ensure the pixel arrangement density of the display panel.

[0110] In at least one embodiment of this disclosure, as shown in Figures 12 and 13, at the isolation opening 301 where there is a centroidal offset from the first electrode 210, the first electrode 210 includes opposing first electrode edges 210a and second electrode edges 210b. The orthographic projection of the first electrode edge 210a on the substrate 100 lies within the orthographic projection of the isolation structure 300 on the substrate 100, and the orthographic projection of the second electrode edge 210b on the substrate 100 lies outside the orthographic projection of the isolation structure 300 on the substrate 100, but within the orthographic projection of the isolation opening 301 on the substrate 100. Thus, on one side of the first electrode edge 210a, the portion of the pixel defining layer 400 raised by the first electrode 210 can extend below the isolation structure 300, thereby further facilitating the film formation conditions of the second electrode 220 on the side of the first electrode edge 210a, thereby facilitating the connection between the second electrode 220 and the isolation structure 300, and reducing the impedance between the second electrode 220 and the isolation structure 300 on the side where the first electrode edge 210a is located.

[0111] It should be noted that the difference between Figure 12 and Figure 13 is that during the fabrication of the display panel, considering the gap between the first electrodes 210, when the pixel defining layer 400 and the isolation structure 300 are subsequently formed, the portion of the film layer used to form the pixel defining layer 400 and the isolation structure 300 that covers the gap of the first electrodes 210 will conform to the gap, thus presenting the structure shown in Figure 13.

[0112] In at least one embodiment of this disclosure, as shown in FIG13, the first electrode 210 includes a main body portion 211 and a connecting portion 212 connected together. The main body portion 211 includes the aforementioned first electrode edge 210a and second electrode edge 210b, and the orthographic projection of the connecting portion 212 on the substrate 100 lies within the orthographic projection of the isolation structure 300 on the substrate 100. Thus, the connecting portion 212 is hidden beneath the isolation structure 300, thereby not affecting the film formation quality (e.g., flatness) of other film layers of the light-emitting device 200 in the isolation opening 301, thus ensuring the quality of the light-emitting device 200.

[0113] In embodiments of this disclosure, as shown in FIG13, the substrate 100 may include a substrate and a driving circuit layer located on the substrate. The driving circuit layer includes multiple pixel driving circuits (e.g., the pixel circuit layer described below) located in the display area, and the light-emitting device 200 is located on the side of the driving circuit layer away from the substrate. For example, the pixel driving circuit may include multiple transistors (TFTs), capacitors, etc., and may be formed in various forms such as 2T1C (i.e., 2 transistors (TFTs) and 1 capacitor (C)), 3T1C, or 7T1C. The pixel driving circuit is connected to the light-emitting device 220 in the display functional layer to control the switching state and brightness of the light-emitting device 200.

[0114] In at least one embodiment of this disclosure, as shown in FIG13, the substrate 100 includes a pixel circuit layer 110 (one of which is shown as a transistor TFT) and a planarization layer 120. The planarization layer 120 is located between the pixel circuit layer 110 and the first electrode 210. A via 121 is provided in the planarization layer 120, and a connection portion 212 is located in the via 121, so that the main body portion 211 of the first electrode 210 is electrically connected to the pixel circuit layer 110 through the via 121 and the connection portion 212.

[0115] In at least one embodiment of this disclosure, as shown in FIG13, the position of the first electrode 210 can be adjusted such that the distance H1 from the surface of the isolation structure 300 away from the substrate 100 on the side where the first electrode edge 210a is located is greater than the distance H2 from the surface of the isolation structure 300 away from the substrate 100 on the side where the second electrode edge 210b is located.

[0116] In at least one embodiment of this disclosure, as shown in FIG13, for the portion of the isolation structure 300 located between two adjacent isolation openings 301, the distance H1 from the surface of the isolation structure 300 away from the substrate 100 to the substrate 100 of the portion of the isolation structure 300 adjacent to one of the isolation openings 301 (e.g., the left isolation opening 301) is greater than the distance H2 from the surface of the isolation structure 300 away from the substrate 100 to the substrate 100 of the portion of the isolation structure 300 adjacent to the other isolation opening 301 (e.g., the right isolation opening 301).

[0117] In at least one embodiment of this disclosure, as shown in FIG13, the orthographic projection of the portion of the isolation structure 300 on the side where the first electrode edge 210a is located on the substrate 100 lies within the orthographic projection of the first electrode 210 on the substrate 100, and the orthographic projection of the portion of the isolation structure 300 on the side where the second electrode edge 210b is located on the substrate 100 lies outside the orthographic projection of the first electrode 210 on the substrate 100. Thus, the first electrode edge 210a of the first electrode 210 extends below the isolation structure 300, and the second electrode edge 210b of the first electrode 210 does not extend below the isolation structure 300, thereby achieving the structure shown in FIG13 through the elevation effect of the first electrode 210.

[0118] In at least one embodiment of this disclosure, as shown in FIG13, the surface of the isolation structure 300 facing away from the substrate 100 includes a first region 321 and a second region 322 at different distances from the substrate 100. In the first region 321 and the second region 322, the orthographic projection of the region at a greater distance from the substrate 100 (e.g., the first region 321) on the substrate 100 overlaps with the orthographic projection of the first electrode 210 on the substrate 100, and the orthographic projection of the region at a smaller distance from the substrate 100 (e.g., the second region 322) on the substrate 100 is located outside the orthographic projection of the first electrode 210 on the substrate 100.

[0119] In at least one embodiment of this disclosure, as shown in FIG13, the light-emitting functional layer 230 and the second electrode 220 of the light-emitting device 200 are confined in the isolation opening 301 and the pixel opening 401. The edge portion of the first electrode 210 is located between the pixel defining layer 400 and the substrate 100. On the side where the edge 210b of the second electrode is located, the portion of the pixel defining layer 400 covering the first electrode 210 forms a stepped structure TT. The orthographic projection of the stepped structure TT on the substrate 100 is located within the orthographic projection of the isolation opening 301 on the substrate 100.

[0120] In at least one embodiment of this disclosure, as shown in FIG13, under the lifting action of the first electrode, the distance from the edge of the light-emitting functional layer 230 on the side where the first electrode edge 210a is located to the substrate 100 is greater than the distance from the edge of the light-emitting functional layer 230 on the side where the second electrode edge 210b is located to the substrate 100; and / or, the display panel further includes a first encapsulation layer 510 covering the isolation opening 301, the first encapsulation layer 510 including encapsulation units 511 respectively covering the light-emitting device 200, the distance from the edge of the encapsulation unit 511 on the side where the first electrode edge 210a is located to the substrate 100 is greater than the distance from the edge of the encapsulation unit 511 on the side where the second electrode edge 210b is located to the substrate 100.

[0121] In at least one embodiment of this disclosure, as shown in FIG13, the second electrode 220 overlaps with one of the two opposing sidewalls of the isolation structure 300 (the sidewall of the isolation structure 300 corresponding to the first electrode sidewall 210a) and has a gap with the other (the sidewall of the isolation structure 300 corresponding to the second electrode sidewall 210b).

[0122] In at least one embodiment of this disclosure, as shown in FIG13, when the first electrode 210 is offset relative to the isolation opening 301, the second electrode 220 overlaps with the isolation structure 300 on the side where the first electrode edge 210a is located, and there is a gap between the second electrode edge 210b and the isolation structure 300, thereby achieving a one-sided overlap with the isolation structure 300.

[0123] In at least one embodiment of this disclosure, as shown in Figures 13 and 14, when the first electrode 210 is offset relative to the isolation opening 301, the multiple light-emitting devices 200 are classified into light-emitting devices 200 with different light-emitting colors, such as first-type light-emitting devices 200a, second-type light-emitting devices 200b, and third-type light-emitting devices 200c. For each light-emitting device 200 with the same light-emitting color, the position where the second electrode 220 overlaps with the sidewall of the isolation structure 300 is located on the same side of the isolation opening 301. Thus, the offset direction of the second electrode 220 corresponding to the light-emitting devices 200 with the same light-emitting color is the same, thereby reducing the manufacturing process difficulty of the display panel and lowering the manufacturing cost of the display panel.

[0124] In at least one embodiment of this disclosure, as shown in FIG14, at least one light-emitting device 200 of a light-emitting color is classified into a first type of light-emitting device 200a and a third type of light-emitting device 200c. The pattern formed by the orthographic projection of at least two adjacent first type light-emitting devices 200a onto the substrate 100 is the same as the shape of the orthographic projection of a third type light-emitting device 200c onto the substrate 100. For all first type light-emitting devices 200a and third type light-emitting devices 200c, the position where the second electrode 220 overlaps with the sidewall of the isolation structure 300 is located on the same side of the isolation opening 301.

[0125] In at least one embodiment of this disclosure, as shown in FIG14, multiple light-emitting devices 200 are classified into light-emitting devices 200 with different light-emitting colors, such as first-type light-emitting devices 200a, second-type light-emitting devices 200b, and third-type light-emitting devices 200c. For light-emitting devices 200 with different light-emitting colors (first-type light-emitting devices 200a and third-type light-emitting devices 200c), the direction from the sidewall of the isolation structure 300 to which the second electrode 220 is attached to to the sidewall of the spaced isolation structure 300 is the same. In this way, the offset direction of the second electrode 220 corresponding to all light-emitting devices 200 is the same, thereby further reducing the manufacturing process difficulty of the display panel and reducing the manufacturing cost of the display panel.

[0126] In at least one embodiment of this disclosure, referring again to FIG7, when the second electrode 220 overlaps with the isolation structure 300 on one side, for light-emitting devices 200 with different light-emitting colors (e.g., second-type light-emitting device 200b and third-type light-emitting device 200c), the direction from the sidewall of the isolation structure 300 to which the second electrode 220 overlaps to the sidewall of the spaced isolation structure 300 is different. Different types of light-emitting devices 200 are fabricated in batches, and the shapes, arrangements, etc., of different types of light-emitting devices 200 may be different. In this technical solution, the offset direction of the second electrode 220 of each type of light-emitting device 200 can be set according to actual needs, so as to reduce the impedance between the second electrode 220 of each type of light-emitting device 200 and the isolation structure 300.

[0127] In at least one embodiment of this disclosure, as shown in FIG15, the display panel may further include a touch function layer 600. The touch function layer 600 is located on the side of the isolation structure 300 facing away from the substrate 100 and forms a first grid pattern. The pixel defining layer 400 forms a second grid pattern, and the pixel opening 401 is a mesh of the second grid pattern. Both the first and second grid patterns include multiple grid lines. The orthographic projection of the center line of at least one grid line of the first grid pattern onto the substrate 100 coincides with the orthographic projection of the center line of at least one grid line of the second grid pattern onto the substrate 100. For example, for the portion of the isolation structure 300 located between adjacent isolation openings 301, the lines corresponding to the boundaries of the pixel openings 401 on both sides of the isolation structure 300 (closest to the isolation structure 300) are L1 and L2. Lines L1 and L2 are perpendicular to the substrate 100, and the distances from the grid lines of the touch function layer 600 to lines L1 and L2 are equal.

[0128] In at least one embodiment of this disclosure, as shown in FIG15, the gaps between the respective first electrodes 210 form a third grid pattern. The second grid pattern includes a plurality of grid lines. The orthographic projection of the center line of at least one grid line of the first grid pattern onto the substrate 100 is outside the orthographic projection of the center line of at least one grid line of the third grid pattern onto the substrate 100. For example, the center of the gap between adjacent first electrodes 210 is located on line L3, which is perpendicular to the substrate 100, and the center of the grid line of the touch functional layer 600 is not on line L3.

[0129] In at least one embodiment of this disclosure, as shown in FIG15, the orthographic projection of the center of at least one grid line of the touch functional layer 600 onto the substrate 100 is outside the orthographic projection of the center of the portion of the isolation structure 300 located adjacent to the isolation opening 301 onto the substrate 100. For example, the center of the portion of the isolation structure 300 located adjacent to the isolation opening 301 is located on line L4, line L4 is perpendicular to the substrate 100, and the center of the grid line of the touch functional layer 600 is not on line L4.

[0130] In at least one embodiment of this disclosure, as shown in FIG15, the display panel may further include a touch function layer 600. The touch function layer 600 is located on the side of the isolation structure 300 opposite to the substrate 100 and forms a first grid pattern. The gaps between the first electrodes 210 form a third grid pattern. Both the first grid pattern and the third grid pattern include a plurality of grid lines. The orthographic projection of the first grid pattern on the substrate 100 is within the orthographic projection of the isolation structure 300 on the substrate 100. The center lines of at least a portion of the grid lines of the first grid pattern are projected onto the substrate 100, while the center lines of the grid lines of the third grid pattern are projected onto the substrate 100 but not onto the substrate 100.

[0131] In at least one embodiment of this disclosure, as shown in Figures 15 and 16, the first mesh pattern of the touch functional layer 600 includes mesh lines classified as first type mesh lines 600a extending along a first direction (e.g., the X-axis direction) and second type mesh lines 600b extending along a second direction (e.g., the Y-axis direction) (a portion of the touch functional layer 600 shown in Figure 15). The third mesh pattern formed by the gaps of the first electrodes 210 includes mesh lines classified as third type mesh lines extending along the first direction and fourth type mesh lines extending along the second direction, with the first and second directions intersecting. The orthographic projection of the center line of the first type mesh line 600a onto the substrate 100 coincides with the orthographic projection of the center line of the third type mesh line onto the substrate 100, and the orthographic projection of the center line of the second type mesh line 600b onto the substrate 100 is outside the orthographic projection of the center line of the fourth type mesh line onto the substrate 100.

[0132] In at least one embodiment of this disclosure, as shown in Figures 15 and 16, the distance between the orthographic projection of the second type of grid line 600b on the substrate 100 and the orthographic projection of the first electrode edge 210a on the substrate 100 is smaller than the distance between the orthographic projection of the second type of grid line 600b on the substrate 100 and the orthographic projection of the second electrode edge 210b on the substrate 100.

[0133] In at least one embodiment of this disclosure, as shown in FIG17, multiple light-emitting devices 200 are classified into a first type of light-emitting device 200a, a second type of light-emitting device 200b, and a third type of light-emitting device 200c, each emitting a different color. The first type of light-emitting device 200a, the second type of light-emitting device 200b, and the third type of light-emitting device 200c are arranged in multiple rows and columns. The first type of light-emitting device 200a, the second type of light-emitting device 200b, and the third type of light-emitting device 200c are arranged in the same row and in a periodic order along the direction of the row. The first type of light-emitting device 200a and the third type of light-emitting device 200c are arranged in the same column, and the column containing the first type of light-emitting device 200a and the third type of light-emitting device 200c alternates with the column containing the second type of light-emitting device 200b. The four second-type light-emitting devices 200b in the Mth row and Nth column, the M+1th row and Nth column, the Mth row and N+2th column, and the M+1th row and N+2th column constitute the first light-emitting device group. The centroid Q2 of the isolation opening 301 corresponding to the light-emitting device 200 within the first light-emitting device group is the vertex of the first virtual quadrilateral P1. The centroid Q1 of the pixel opening 401 corresponding to the first light-emitting device group is the vertex of the second virtual quadrilateral P2. The first virtual quadrilateral P1 and the second virtual quadrilateral P2 do not completely overlap. The centroid Q4 of the first virtual quadrilateral P1 is located outside the centroid Q3 of the second virtual quadrilateral P2. M and N are both positive integers. With this pixel arrangement, it is convenient to offset the pixel opening 401 corresponding to the light-emitting device 200, and while ensuring a high pixel density (PPI), further reduce the impedance between the second electrode 220 and the isolation structure 300 in the entire display panel.

[0134] In at least one embodiment of this disclosure, as shown in Figures 18 and 19, multiple light-emitting devices 200 are classified into a first type of light-emitting device 200a, a second type of light-emitting device 200b, and a third type of light-emitting device 200c, each emitting a different color. The first type of light-emitting device 200a, the second type of light-emitting device 200b, and the third type of light-emitting device 200c are arranged into multiple pixel units. Each pixel unit includes one first type of light-emitting device 200a, two second type of light-emitting devices 200b, and two third type of light-emitting devices 200c. In each pixel unit, the centroid Q2 of the orthographic projection of the isolation opening 301 corresponding to the two second type of light-emitting devices 200b onto the substrate 100 is located at the first vertex of the third virtual quadrilateral P3, and the centroid Q2 of the orthographic projection of the isolation opening 301 corresponding to the two third type of light-emitting devices 200c onto the substrate 100 is located at the second vertex of the third virtual quadrilateral P3. The first and second vertices alternate and are spaced apart. The isolation opening 301 corresponding to the first type of light-emitting device 200a is located inside the third virtual quadrilateral P3. The centroid Q1 of the orthographic projection of the pixel openings 401 corresponding to the two second-type light-emitting devices 200b and the two third-type light-emitting devices 200c of the pixel unit onto the substrate 100 is the vertex of the fourth virtual quadrilateral P4. The third virtual quadrilateral P3 and the fourth virtual quadrilateral P4 do not completely overlap, and the centroid Q4 of the third virtual quadrilateral P3 is located outside the centroid Q3 of the fourth virtual quadrilateral P4. With this pixel arrangement, it is convenient to offset the pixel openings 401 corresponding to the light-emitting devices 200, and while ensuring a high pixel density (PPI), the impedance between the second electrode 220 and the isolation structure 300 in the entire display panel is further reduced. In this disclosure, "two virtual quadrilaterals not completely overlapping" means that the four sides of the two virtual quadrilaterals do not overlap partially or do not overlap at all.

[0135] In at least one embodiment of this disclosure, as shown in FIG20, in the third virtual quadrilateral P3, the centroid Q5 of the orthographic projection of the isolation opening 301 corresponding to the first type of light-emitting device 200a onto the substrate 100 is equal to the centroid Q2 of the orthographic projection of the isolation opening 301 corresponding to any third type of light-emitting device 200c onto the substrate 100, and the second distance R2 of the centroid of the orthographic projection of the isolation opening 301 corresponding to the first type of light-emitting device 200a onto the substrate 100 to the centroid Q2 of the orthographic projection of the isolation opening 301 corresponding to any second type of light-emitting device 200b onto the substrate 100 is equal, and the first distance R1 and the second distance R2 are equal. At least one embodiment of this disclosure provides a display panel, which includes a substrate 100 and an isolation structure 300, a pixel defining layer 400, and a plurality of light-emitting devices 200 located on the substrate 100. The light-emitting device 200 includes a first electrode 210, a light-emitting functional layer 230, and a second electrode 220 sequentially stacked on a substrate 100. The isolation structure 300 includes a plurality of isolation openings 301, and the light-emitting functional layer 230 and the second electrode 220 of the light-emitting device 200 are confined within the isolation openings 301. At at least one isolation opening 301, the centroid of the orthographic projection of the first electrode 210 onto the substrate 100 is located outside the centroid of the orthographic projection of the isolation opening 301 onto the substrate 100. In this display panel, the first electrode 210 can be offset along with the pixel opening 401 (the offset direction and size can be the same or different) to adjust the distribution of the portion of the pixel defining layer 400 covering the edge of the first electrode 210 (which will be raised by the first electrode 210), thereby adjusting the impedance at different connection points between the second electrode 220 and the isolation structure 300. For the structure of the display panel in this embodiment, further improvements, etc., please refer to the relevant descriptions in the foregoing embodiments (e.g., the embodiment shown in FIG. 13), which will not be repeated here.

[0136] In at least one embodiment of this disclosure, the display panel may further include a pixel defining layer 400 located between the substrate 100 and the isolation structure 300. The pixel defining layer 400 includes a pixel opening 401 communicating with the isolation opening 301. The light-emitting functional layer 230 and the second electrode 220 of the light-emitting device 200 are confined within the isolation opening 301 and the pixel opening 401. The centroid of the orthographic projection of the first electrode 210 onto the substrate 100 is located outside the centroid of the orthographic projection of the pixel opening 401 onto the substrate 101. For the structure of the display panel in this embodiment, further improvements, etc., please refer to the relevant descriptions in the foregoing embodiments (e.g., the embodiment shown in FIG. 13), which will not be repeated here.

[0137] In at least one embodiment of this disclosure, at the isolation opening 301 where there is a centroidal offset from the first electrode 210, the first electrode 210 includes opposing first electrode edges 210a and second electrode edges 210b. The orthographic projection of the first electrode edge 210a on the substrate 100 lies within the orthographic projection of the isolation structure 300 on the substrate 100, and the orthographic projection of the second electrode edge 210b on the substrate 100 lies outside the orthographic projection of the isolation structure 300 on the substrate 100, but within the orthographic projection of the isolation opening 301 on the substrate 100. The structure of the display panel in this embodiment, further improvements, etc., can be found in the relevant descriptions of the foregoing embodiments (e.g., the embodiment shown in FIG. 13), and will not be repeated here.
