Description

Display panel and display device Technical Field

[0001] At least one embodiment of this disclosure relates to a display panel and a display device. Background Technology

[0002] With the continuous development of display technology, users' requirements for the performance and display effect of display devices are constantly increasing. Polarizer (POL) technology and color filter on encapsulation (COE) technology are two important implementation methods in the field of display technology.

[0003] For example, a polarizer is a key component in liquid crystal display (LCD) imaging, controlling the polarization direction of a specific light beam. A polarizer converts natural light into polarized light, enabling LCD imaging. By adjusting the polarization direction of the polarizer, the brightness and contrast of the displayed image can be controlled. Similarly, COE technology is a technique that deposits a color filter layer after encapsulating an Active Matrix Organic Light Emitting Diode (AMOLED). The advantage of COE technology lies in its ability to effectively improve the contrast and brightness of the display. It is suitable for flexible and foldable display technologies, helping to reduce screen thickness and weight. Summary of the Invention

For example, the two blue sub-pixels 30 in a blue sub-pixel pair can share a mask when forming the light-emitting functional layer, which helps to save pixel space in the product and increase the pixel aperture ratio. However, the pixel density, pixel space utilization, and pixel aperture ratio in the above-mentioned display panel still need to be improved.

[0071] At least one embodiment of this disclosure provides a display panel, including: a substrate and a plurality of sub-pixels located on the substrate. Each sub-pixel includes a light-emitting functional layer and a first electrode and a second electrode located on both sides of the light-emitting functional layer along a direction perpendicular to the substrate. The first electrode is located between at least a portion of the light-emitting functional layer and the substrate. The plurality of sub-pixels are divided into a plurality of repeating units. Each repeating unit includes a plurality of first color sub-pixels, a plurality of second color sub-pixels, and at least one third color sub-pixel. The first electrode of the at least one third color sub-pixel includes a first electrode portion extending along a first direction and a second electrode portion extending along a second direction. The first electrode portion and the second electrode portion divide the repeating unit into two regions. Each region is provided with at least one first color sub-pixel and at least one second color sub-pixel. Both the first direction and the second direction are parallel to the substrate, and the first direction intersects the second direction.

[0072] In the display panel provided by the embodiments of this disclosure, each repeating unit includes a plurality of first color sub-pixels, a plurality of second color sub-pixels, and at least one third color sub-pixel. This allows for a more compact arrangement of the multiple sub-pixels in the display panel, which is beneficial for increasing pixel density and making the display effect of the display panel clearer and more delicate. In addition, the first electrode portion and the second electrode portion of at least one third color sub-pixel divide the repeating unit into two regions. This is beneficial for at least one first color sub-pixel and at least one second color sub-pixel in each region to form a display unit with at least one of the first electrode portion and the second electrode portion. Furthermore, it is beneficial for at least one third color sub-pixel in the repeating unit to share a mask opening when fabricating the light-emitting functional layer. This simplifies the manufacturing process and helps to increase the pixel aperture ratio while reasonably arranging the layout space.

[0073] At least one embodiment of this disclosure also provides a display panel, including a substrate, a plurality of sub-pixels, and a pixel defining pattern. The plurality of sub-pixels are located on the substrate, and each sub-pixel includes a light-emitting functional layer, and a first electrode and a second electrode located on both sides of the light-emitting functional layer along a direction perpendicular to the substrate. The first electrode is located between at least a portion of the light-emitting functional layer and the substrate. At least a portion of the pixel defining pattern is located between the light-emitting functional layer and the first electrode. The pixel defining pattern includes a pixel opening and a pixel defining portion located between adjacent pixel openings. The pixel opening exposes at least a portion of the first electrode. The light-emitting functional layer is contacted with the first electrode through the pixel opening. The plurality of sub-pixels are divided into a plurality of repeating units. Each repeating unit includes a plurality of first-color sub-pixels, a plurality of second-color sub-pixels, and at least one third-color sub-pixel. The pixel opening corresponding to the at least one third-color sub-pixel in each repeating unit divides the repeating unit into two regions. Each region has at least one pixel opening corresponding to a first-color sub-pixel and at least one pixel opening corresponding to a second-color sub-pixel.

[0074] In the display panel provided by the embodiments of this disclosure, each repeating unit includes multiple first color sub-pixels, multiple second color sub-pixels, and at least one third color sub-pixel. This allows for a more compact arrangement of the multiple sub-pixels in the display panel, which is beneficial for increasing pixel density and making the display panel's display effect clearer and more delicate. In addition, the pixel opening corresponding to at least one third color sub-pixel divides the repeating unit into two regions. This is beneficial for the pixel openings corresponding to at least one first color sub-pixel and at least one second color sub-pixel in each region to correspond to the light-emitting area of ​​the same display unit with the pixel opening corresponding to at least one third color sub-pixel. This is also beneficial for at least one third color sub-pixel in the repeating unit to share a mask opening when fabricating the light-emitting functional layer, thereby simplifying the manufacturing process and increasing the pixel aperture ratio while reasonably arranging the layout space.

[0075] Figure 3 is a partial plan view of a display panel provided in at least one embodiment of the present disclosure; Figure 4A is a partial layout diagram corresponding to the display panel in Figure 3; Figure 4B is a plan view of the first electrode of the third color sub-pixel in Figure 4A.

[0076] As shown in Figures 3 to 4B, the display panel includes a substrate 001 and a plurality of sub-pixels 100 located on the substrate 001. Each sub-pixel 100 includes a light-emitting functional layer (not shown in the figure), and a first electrode 101 and a second electrode (not shown in the figure) located on both sides of the light-emitting functional layer in a direction perpendicular to the substrate 001. The first electrode 101 is located between at least a portion of the light-emitting functional layer and the substrate 001.

[0077] For example, as shown in Figures 3-4B, the light-emitting functional layer includes multiple film layers. For example, the light-emitting functional layer may include a light-emitting layer for emitting light and a charge-generating layer. The charge-generating layer has strong conductivity, which enables the light-emitting functional layer to have advantages such as long lifespan, low power consumption, and high brightness. For example, the light-emitting functional layer can be a film layer in an organic light-emitting element. For example, the light-emitting functional layer may include a first light-emitting layer (EML), a charge-generating layer (CGL), and a second light-emitting layer (EML) stacked together, with the charge-generating layer located between the first and second light-emitting layers. It should be noted that the light-emitting functional layer shown in Figure 3 may also include other film layers, such as a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL), etc., and the embodiments of this disclosure are not limited to these. For example, the hole injection layer, hole transport layer, electron transport layer, electron injection layer, charge-generating layer, and second electrode are all common film layers of multiple sub-pixels 100, which can be called common layers.

[0078] For example, as shown in FIG3, subpixel 100 may include a tandem light-emitting element, such as a tandem OLED, but embodiments of this disclosure are not limited thereto.

[0079] For example, as shown in Figure 4, the display panel may also include a pixel driving circuit, which may be connected to the first electrode 101 to drive the light-emitting functional layer to emit light.

[0080] As shown in Figures 3-4B, multiple sub-pixels 100 are divided into multiple repeating units 1000 (the sub-pixels within the dashed boxes 1000 in Figure 3 constitute one repeating unit). Each repeating unit 1000 includes multiple first-color sub-pixels 110, multiple second-color sub-pixels 120, and at least one third-color sub-pixel 130. For example, the first-color sub-pixel 110 can be a red sub-pixel, the second-color sub-pixel 120 can be a green sub-pixel, and the third-color sub-pixel 130 can be a blue sub-pixel, but this is not limited to these. The embodiments of this disclosure do not limit the emission color of the first-color sub-pixels 110, the second-color sub-pixels 120, and the third-color sub-pixels 130.

[0081] As shown in Figures 3-4B, the first electrode 101 of at least one third color sub-pixel 130 includes a first electrode portion 131 and a second electrode portion 132. The first electrode portion 131 and the second electrode portion 132 divide the repeating unit 1000 into two regions, each region being provided with at least one first color sub-pixel 110 and at least one second color sub-pixel 120. The second electrode portion 132 extends along a first direction X, and the first electrode portion 131 extends along a second direction Y.

[0082] For example, as shown in Figures 3-4B, the first electrode portion 131 and the second electrode portion 132 can be two parts of the first electrode 130 of the third color sub-pixel 130. The first electrode 130 of the third color sub-pixel 130 also includes a connecting portion 140, through which the two parts can be connected. In some embodiments, when the at least one third color sub-pixel 130 includes multiple third color sub-pixels 130, the first electrode portion 131 and the second electrode portion 132 can be the first electrodes of different third color sub-pixels 130. Please refer to the relevant descriptions of the embodiments below for details. The embodiments of this disclosure do not limit the specific configuration of the first electrode portion 131 and the second electrode portion 132.

[0083] As shown in Figures 3-4B, the two regions can be a first region 010 and a second region 020, and the first region 010 and the second region 020 can be located on opposite sides of the first electrode portion 131 in the first direction X. For example, a first color sub-pixel 110 and a second color sub-pixel 120 can be provided in the first region 010, and a first color sub-pixel 110 and a second color sub-pixel 120 can also be provided in the second region 020, but this is not limited to these. For example, the number of sub-pixels 100 in the first region 010 can be the same as or different from the number of sub-pixels 100 in the second region 020, and the embodiments of this disclosure do not limit this. For example, a repeating unit 100 can include at least two display units. For example, the first color sub-pixel 110 and the second color sub-pixel 120 in the first region 010 can form a display unit with at least a portion of the first electrode 101 of the third color sub-pixel 130, and the first color sub-pixel 110 and the second color sub-pixel 120 in the second region 020 can form another display unit with at least a portion of the first electrode 101 of the third color sub-pixel 130.

[0084] As shown in Figures 3-4B, both the first direction X and the second direction Y are parallel to the substrate 001, and the first direction X intersects the second direction Y. For example, the first direction X is perpendicular to the second direction Y, but it is not limited to this.

[0085] In the display panel provided by the embodiments of this disclosure, each repeating unit includes a plurality of first color sub-pixels, a plurality of second color sub-pixels, and at least one third color sub-pixel. This allows for a more compact arrangement of the multiple sub-pixels in the display panel, which is beneficial for increasing pixel density and making the display effect of the display panel clearer and more delicate. In addition, the first electrode portion and the second electrode portion of at least one third color sub-pixel divide the repeating unit into two regions. This is beneficial for at least one first color sub-pixel and at least one second color sub-pixel in each region to form a display unit with at least one of the first electrode portion and the second electrode portion. Furthermore, it is beneficial for at least one third color sub-pixel in the repeating unit to share a mask opening when fabricating the light-emitting functional layer. This simplifies the manufacturing process and helps to increase the pixel aperture ratio while reasonably arranging the layout space.

[0086] For example, as shown in Figures 3-4B, a repeating unit 1000 may include three regions: a first region 010, a second region 020, and a third region 030 where the third color sub-pixel 130 of the repeating unit 1000 is located. For example, sub-pixels 100 in the first region 010 and sub-pixels 100 in the third region 030 can constitute one display unit, and sub-pixels 100 in the second region 020 and sub-pixels 100 in the third region 030 can constitute another display unit. The sub-pixels 100 in the third region 030 can be referred to as "shared sub-pixels".

[0087] For example, as shown in Figures 3-4B, the pixel openings corresponding to the first electrode 101 of the third color sub-pixel 130 are arranged in an "L" shape. For example, the first region 010 is located outside the "L"-shaped first electrode 101, and the second region 020 is located inside the "L"-shaped first electrode 101. Of course, the orthographic projection of the first electrode 101 of the third color sub-pixel 130 onto the substrate 001 can also be of other shapes, as long as the repeating unit 1000 can be divided into two regions to facilitate the formation of different display units.

[0088] For example, as shown in Figures 3-4B, the orthographic projection of the opening of the fabrication mask for the light-emitting functional layer of the third color sub-pixel 130 onto the substrate 001 is also "L"-shaped, which helps to increase the aperture ratio and simplify the structure of the fabrication mask. For example, the orthographic projection of the opening of the fabrication mask for the light-emitting functional layer of the third color sub-pixel 130 corresponding to the first electrode portion 131 onto the substrate 001 is rectangular, and the orthographic projection of the opening of the fabrication mask for the light-emitting functional layer of the third color sub-pixel 130 corresponding to the second electrode portion 132 onto the substrate 001 is also rectangular, which makes the structure of the fabrication mask more flexible. The embodiments of this disclosure do not limit the structure of the fabrication mask for the light-emitting functional layer of the third color sub-pixel 130.

[0089] Figure 5 is a partially enlarged schematic diagram of a display panel; Figure 6 is a cross-sectional schematic diagram of a specific area in Figure 5. For example, the characteristic area in Figure 5 is the area enclosed by the circle.

[0090] As shown in Figures 5 and 6, dark spots appeared in specific areas. This is because the orthographic projection area of ​​the first electrode 101 of the sub-pixel corresponding to the dark spot on the substrate is relatively large. This makes it difficult for the gas in the insulating layer 104 (e.g., planarization layer) on the side of the first electrode 101 away from the second electrode 102 to be released, which in turn causes corrosion of the first electrode 101. After high-temperature processes such as evaporation followed by baking, the metal (e.g., silver) in the first electrode 101 grows and migrates, breaking through the light-emitting functional layer and contacting the second electrode 102, resulting in a local short circuit and causing the dark spot. Therefore, when the orthographic projection area of ​​the first electrode 101 of the sub-pixel on the substrate is too large, the incidence of dark spots is easily increased.

[0091] For example, as shown in Figures 3-4B, the display panel further includes a pixel defining pattern 200, at least a portion of which is located between the light-emitting functional layer and the first electrode 101 in a direction perpendicular to the substrate 001. The pixel defining pattern 200 includes a pixel opening 210 and a pixel defining portion 220 located between adjacent pixel openings 210. The pixel opening 210 exposes at least a portion of the first electrode 101 to define the light-emitting area of ​​the sub-pixel 100. The light-emitting functional layer is disposed in contact with the first electrode 101 through the pixel opening 210. For example, the first electrode 101 and the second electrode 102 located on both sides of the light-emitting functional layer can drive the light-emitting functional layer located between them to emit light. For example, the light-emitting area of ​​the sub-pixel 100 refers to the area where the sub-pixel 100 effectively emits light, and the shape of the light-emitting area refers to a two-dimensional shape. For example, the shape of the light-emitting area may be the same as the shape of the orthographic projection of the portion of the first electrode 101 exposed by the pixel opening 210 onto the substrate 001.

[0092] For example, as shown in Figures 3-4B, the first electrode portion 131 and the second electrode portion 132 correspond to different pixel openings 210. The first electrode portion 131 corresponds to two pixel openings 210-1 and 210-2 that are spaced apart in the second direction Y, and the second electrode portion 132 corresponds to pixel opening 210-3. For example, the orthographic projection area of ​​pixel opening 210-3 on the substrate 001 is larger than the orthographic projection area of ​​pixel opening 210-2 on the substrate 001, and larger than the orthographic projection area of ​​pixel opening 210-1 on the substrate 001. For example, the orthographic projection area of ​​pixel opening 210-2 on the substrate 001 is larger than the orthographic projection area of ​​pixel opening 210-1 on the substrate 001, but this is not a limitation, and the embodiments of this disclosure do not limit this.

[0093] This configuration allows the first electrode of the third color sub-pixel to be divided into multiple different light-emitting areas, which helps to avoid the first electrode being set too concentrated, thereby reducing the risk of dark spots.

[0094] For example, as shown in Figures 3-4B, a first color sub-pixel 110 and a second color sub-pixel 120 are arranged along the second direction Y in the first region 010, and another first color sub-pixel 110 and another second color sub-pixel 120 are arranged along the first direction X in the second region 020. For example, the pixel opening 210 of the first color sub-pixel 110 and the pixel opening 210 of the second color sub-pixel 120 in the first region 010 have substantially the same size in the first direction X, and the edge of the pixel opening 210 of the second color sub-pixel 120 away from the first color sub-pixel 110 is approximately equal to the edge of the pixel opening 210 corresponding to the second electrode portion 132 away from the second region 020.

[0095] This configuration allows the sub-pixels in the first and second regions to share the third color sub-pixel, thus forming display units with the third color sub-pixel. This saves pixel arrangement space, increases pixel density, and improves display quality. In addition, the light-emitting functional layer of the third color sub-pixel can share a mask opening during the manufacturing process, which helps to increase the pixel aperture ratio.

[0096] For example, as shown in Figures 3 to 4B, the multiple repeating units 1000 in the display panel include a first repeating unit 1001 and a second repeating unit 1002 arranged along a first direction X. The second region 020 of the first repeating unit 1001 is adjacent to the first region 010 of the second repeating unit 1002, and the light emission color of the adjacent sub-pixels 1000 in the second region 020 of the first repeating unit 1001 and the first region 010 of the second repeating unit 1002 in the first direction X is different. At least one of the two edges of two adjacent sub-pixels 100 of the same color in the second region 020 of the first repeating unit 1001 and the first region 010 of the second repeating unit 1002 is provided with a chamfer.

[0097] For example, as shown in Figures 3 to 4B, in each repeating unit 1000, the first color sub-pixel 110 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same pixel row, the second color sub-pixel 120 in the first region 010 and the second electrode portion 132 are located in the same pixel row, and the first color sub-pixel 110 in the second region 020 is closer to the first electrode portion 131 in the first direction X than the second color sub-pixel 120. Therefore, the second color sub-pixel 120 in the second region 020 of the first repeating unit 1001 and the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002 are adjacent in the first direction X. The second color sub-pixel 120 in the second region 020 of the first repeating unit 1001 and the second color sub-pixel 120 in the first region 010 of the second repeating unit 1002 are adjacent to each other and are the same color sub-pixel 100. In this case, at least one of the two edges of the adjacent second color sub-pixels 120 in the second region 020 of the first repeating unit 1001 and the first region 010 of the first repeating unit 1002 is provided with a chamfer.

[0098] For example, as shown in Figures 3-4B, this embodiment uses the example of a second color sub-pixel 120 in the second region 020 of the first repeating unit 1001 having a chamfer U1 and a second color sub-pixel 120 in the first region 010 of the second repeating unit 1002 having a chamfer U2, but it is not limited thereto. In some embodiments, a chamfer can be provided on one of the two adjacent edges of the second color sub-pixels 120 in the second region 020 of the first repeating unit 1001 and the first region 010 of the second repeating unit 1002, and the embodiments of this disclosure do not limit this.

[0099] This arrangement helps to maintain a certain distance (e.g., 7-8 micrometers) between the two adjacent edges (such as the edge of the first electrode) of two identical color sub-pixels in the second region of the first repeating unit and the first region of the second repeating unit. This allows the portion of the pixel-defining pattern located within this distance to have sufficient space, thereby enabling the pixel-defining portion located between the two adjacent identical color sub-pixels to have a good morphology. Consequently, it can have a good slope angle at the pixel opening, which helps to ensure a good light emission effect.

[0100] In some embodiments, referring to FIGS. 3 to 4B, in each repeating unit 1000, the second color sub-pixel 120 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same pixel row, and the first color sub-pixel 110 in the first region 010 and the second electrode portion 132 are located in the same pixel row. The first color sub-pixel 110 in the second region 020 is farther away from the first electrode portion 131 in the first direction X than the second color sub-pixel 120. In this case, at least one of the two adjacent edges of the first color sub-pixels 110 in the second region 020 of the first repeating unit 1001 and the first region 010 of the second repeating unit 1002 is provided with a chamfer. The embodiments of this disclosure do not limit the position of each sub-pixel 100 in the first region 010 and the second region 020.

[0101] For example, as shown in Figures 3 to 4B, when the two edges of the adjacent second color sub-pixels 120 in the second region 020 of the first repeating unit 1001 and the first region 010 of the second repeating unit 1002 are both provided with chamfers, the embodiments of this disclosure do not limit the size of the two chamfers, as long as the distance between the two edges can meet the requirements.

[0102] For example, as shown in Figures 3 to 4B, the first electrode portion 131 and the second electrode portion 132 are connected by a connecting portion 140, and the first electrode 110 of the third color sub-pixel 130 is a single-piece structure. For example, the first electrode portion 131 and the second electrode portion 132 are arranged adjacent to each other in the first direction X, and the connecting portion 140 extends along the first direction X.

[0103] By dividing the first electrode of the third color sub-pixel into different first electrode portions and second electrode portions, it is beneficial to avoid the first electrode of the third color sub-pixel being too concentrated, thereby reducing the risk of dark spots. In addition, since the first electrode portion and the second electrode portion are connected by a connecting portion, they can be turned on at the same time, which simplifies the control process.

[0104] For example, as shown in Figures 3-4B, at least one of the first electrode portion 131 and the second electrode portion 132 includes at least one sub-electrode portion 1310, and each sub-electrode portion 1310 corresponds to a pixel opening 210. For example, the first electrode portion 131 and the second electrode portion 132 may each include multiple sub-electrode portions 1310 to reduce the risk of dark spots. For example, the number of sub-electrode portions 1310 included in the first electrode portion 131 and the second electrode portion 132 may be different, as long as the distance between adjacent sub-electrode portions 1310 meets the manufacturing process requirements, which can be set according to design requirements. In addition, the embodiments of this disclosure do not limit the orthographic shape, orthographic area, and positional distribution of the multiple sub-electrode portions 1310 on the substrate 001. For example, the angle between the extension direction of the sub-electrode portion 1310 and the first direction X may be greater than 0 degrees and less than 90 degrees, that is, the sub-electrode portion 1310 may be inclined relative to the first direction X.

[0105] For example, as shown in Figures 3-4B, the first electrode portion 131 includes a first sub-electrode portion 1311 and a second sub-electrode portion 1312 that are adjacent and spaced apart in the second direction Y. The first electrode 101 of the third color sub-pixel 130 also includes a first connecting electrode 141 that connects the first sub-electrode portion 1311 and the second sub-electrode portion 1312. For example, the first sub-electrode portion 1311, the first connecting electrode 141, and the second sub-electrode portion 1312 are arranged sequentially in the second direction Y, and the edges of the first sub-electrode portion 1311, the first connecting electrode 141, and the second sub-electrode portion 1312 near the second electrode portion 132 are substantially flush.

[0106] Therefore, while saving the layout space occupied by the first electrode portion, it is beneficial to avoid the first electrode portion being too concentrated, thereby reducing the risk of dark spots.

[0107] In some embodiments, the second electrode portion may also include multiple sub-electrode portions. For example, the multiple sub-electrode portions of the second electrode portion may be spaced apart from each other, or at least some of the sub-electrode portions may be connected to each other, and the embodiments of this disclosure are not limited thereto. For example, the multiple sub-electrode portions in the second electrode portion may be arranged sequentially along a first direction, but are not limited thereto. For example, the orthographic projection areas of the multiple sub-electrode portions on the substrate may be different, or they may have different orthographic projection shapes. The arrangement of the multiple sub-electrode portions is not limited to the examples shown in the accompanying drawings of this disclosure, and can be flexibly set according to design needs.

[0108] For example, as shown in Figures 3-4B, the second electrode portion 132 and the second sub-electrode portion 1312 are located in the same row. For instance, the second color sub-pixel 120, the second sub-electrode portion 1312, and the second electrode portion 132 in the first region 010 are all located in the same row, while the first color sub-pixel 110, the first sub-electrode portion 1311 in the first region 010, and the plurality of sub-pixels 100 in the second region 020 are all located in another row. The projected area of ​​the second electrode portion 132 on the substrate 001 is larger than the projected area of ​​any sub-pixel 100 in the second region 020 on the substrate 001. This arrangement allows the plurality of sub-pixels 100 in the repeating unit 1000 to be positioned reasonably and orderly.

[0109] For example, as shown in Figures 3-4B, sub-pixel 100 further includes a pixel driving circuit configured to drive sub-pixel 100 to emit light. For example, in a direction perpendicular to the substrate, the pixel driving circuit is located between the first electrode 101 of sub-pixel 100 and the substrate 001. An insulating layer (e.g., a planarization layer) is provided between the first electrode 101 of sub-pixel 100 and the pixel driving circuit. The insulating layer includes a connection via N, and the first electrode 101 of sub-pixel 100 is connected to the pixel driving circuit through the connection via N. For example, the pixel driving circuit may include multiple transistors and at least one capacitor (not shown in the figures). The first electrode 101 can be electrically connected to the pixel driving circuit through the connection via N to drive the light-emitting functional layer to emit light.

[0110] For example, the pixel driving circuit can be a 7T1C (i.e., seven transistors and one capacitor) structure, or it can be a structure including other numbers of transistors, such as a 7T2C structure, a 6T1C structure, a 6T2C structure or a 9T2C structure. The embodiments disclosed herein do not limit this.

[0111] For example, as shown in Figures 3-4B, in the second direction Y, there is a gap G1 between the first sub-electrode portion 1311 and the second sub-electrode portion 1312, and the connecting via N corresponding to one of the first color sub-pixels 110 and the second color sub-pixels 120, as well as the first connecting electrode 141, are all located in the gap G1. For example, the connecting via N corresponding to the second color sub-pixel 120 is located in the gap G1.

[0112] This configuration allows the first electrode of the third color sub-pixel to avoid the connecting vias corresponding to the first or second color sub-pixel, thereby improving the flatness of the first electrode of the third color sub-pixel and ensuring good light output.

[0113] For example, as shown in Figures 3-4B, in the second direction Y, the connecting vias N corresponding to the sub-pixels 100 in the repeating unit 1000 are all located between the pixel rows where the first color sub-pixels 110 and the second color sub-pixels 120 are located in the first region 010. For example, in the first direction X, the connecting vias N corresponding to the first color sub-pixels 110, the connecting vias N corresponding to the second color sub-pixels 120, and the connecting vias N corresponding to the third color sub-pixels 130 in the first region 010, the connecting vias N corresponding to the first color sub-pixels 110 and the connecting vias N corresponding to the second color sub-pixels 120 in the second region 020 are arranged sequentially at intervals, and the distance between adjacent connecting vias N is approximately equal.

[0114] This configuration ensures the flatness of the first electrode of the sub-pixel in the repeating unit, while reducing the layout space occupied by the sub-pixel in the repeating unit and making the positional distribution of each sub-pixel in the repeating unit more reasonable and orderly.

[0115] For example, as shown in Figures 3-4B, the display panel also includes multiple data lines D. The data lines D extend along the second direction Y and are configured to transmit data signals. For example, the multiple data lines D include multiple specific data lines D0 overlapping with the first electrode 101 of the third color sub-pixel 130. For example, a repeating unit 1000 may correspond to multiple specific data lines D0. For example, a third color sub-pixel 130 may overlap with multiple specific data lines D0, but this is not a limitation; the embodiments of this disclosure do not limit the number and position of the specific data lines D0.

[0116] For example, as shown in FIG3, the first electrode portion 131 and the second electrode portion 132 are spaced apart in the first direction X, and at least a portion of at least one specific data line D0 is located in the interval G2 between the first electrode portion 131 and the second electrode portion 132 in the first direction X. For example, the specific data line D0 may not overlap with either the first electrode portion 131 or the second electrode portion 132, thereby reducing the coupling capacitance between the specific data line D0 and the first electrode portion 131, and reducing the coupling capacitance between the specific data line D0 and the second electrode portion 132, thereby reducing the risk of crosstalk (e.g., in the direction perpendicular to the substrate).

[0117] For example, as shown in FIG3, at least one specific data line D0 includes a first data line D1. The orthographic projection of the first data line D1 on the substrate 001 at least partially overlaps with the orthographic projection of the first electrode portion 131 on the substrate 001, and is spaced apart from the orthographic projection of the second electrode portion 132 on the substrate 001. For example, the overlapping area of ​​the orthographic projection of the first data line D1 on the substrate 001 and the orthographic projection of the first electrode portion 131 on the substrate 001 is smaller than the orthographic projection area of ​​the first data line D1 on the substrate 001. For example, the overlapping area can be 5% to 30% of the orthographic projection area of ​​the first data line D1 on the substrate 001, but is not limited to this. This allows for minimizing the parasitic capacitance between the first data line D1 and the first electrode portion 131 while meeting layout distribution requirements, thereby reducing the risk of crosstalk.

[0118] Figure 7 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 8 is a partial layout view corresponding to the display panel in Figure 7.

[0119] For example, as shown in Figure 7, the difference between this display panel and the display panel shown in Figure 3 is that the second region 020 of the repeating unit 1000 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0120] For example, as shown in Figures 7 and 8, the first color sub-pixel 110 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same row, and the second color sub-pixel 120 in the first region 010 and the second electrode portion 132 are located in the same row. For example, the first electrode 101 of the first color sub-pixel 110 in the second region 020 is farther away from the first electrode portion 131 in the first direction X than the first electrode 101 of the second color sub-pixel 120. For example, the first color sub-pixel 110 in the second region 020 of the first repeating unit 1001 and the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002 are adjacent to each other in the first direction X.

[0121] This configuration allows the light-emitting functional layers of the first color sub-pixels in the second region of the first repeating unit and the first color sub-pixels in the first region of the second repeating unit to share a common mask opening, thereby increasing the setting range of the light-emitting functional layers of the two first color sub-pixels and simplifying the manufacturing process, which in turn helps to increase the pixel aperture ratio.

[0122] In some embodiments, referring to FIGS. 7 and 8, the first color sub-pixel 110 in the first region 010 is located in the same row as the second electrode portion 132, and the second color sub-pixel 120 in the first region 010 is located in the same row as the sub-pixel 100 in the second region 020. For example, the first electrode 101 of the first color sub-pixel 110 in the second region 020 is closer to the first electrode portion 131 in the first direction X than the first electrode 101 of the second color sub-pixel 120. For example, the second color sub-pixel 120 in the second region 020 of the first repeating unit 1001 and the second color sub-pixel 120 in the first region 010 of the second repeating unit 1002 are adjacent to each other in the first direction X, so that the second color sub-pixels in the second region of the first repeating unit and the second color sub-pixels in the first region of the second repeating unit can share the mask opening of the light-emitting functional layer, thereby increasing the pixel aperture ratio.

[0123] Figure 9 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 10 is a partial layout view corresponding to the display panel in Figure 9.

[0124] For example, as shown in Figure 9, the difference between this display panel and the display panel shown in Figure 7 is that the third color sub-pixel 130 in the repeating unit 1000 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0125] For example, as shown in Figures 9 and 10, the first electrode portion 131 and the second electrode portion 132 are arranged sequentially in the second direction Y. The first electrode 101 of the third color sub-pixel 130 also includes a connecting portion 140 connecting the first electrode portion 131 and the second electrode portion 132. For example, in the first direction X, the first electrode 101 and the second electrode portion 132 of the second color sub-pixel 120 are adjacent to each other. The orthogonal projection area of ​​the second electrode portion 132 on the substrate 001 is larger than the orthogonal projection area of ​​the first electrode portion 131 on the substrate 001. For example, the orthogonal projection area of ​​the first electrode 101 of each sub-pixel 100 in the first region 010 and the second region 020 on the substrate 001 is smaller than the orthogonal projection area of ​​the second electrode portion 132 on the substrate 001.

[0126] This configuration avoids overly concentrated placement of the first electrode of the third color sub-pixel, reduces the risk of dark spots, and facilitates enlarging the pixel aperture corresponding to the second electrode, thereby increasing its pixel aperture ratio.

[0127] For example, as shown in Figures 9 and 10, a gap G4 exists between the first electrode portion 131 and the first electrode 101 of the adjacent sub-pixel 100 in the second region 020 (e.g., the first electrode 101 of the second color sub-pixel 120). At least one specific data line D0 includes a first data line D1, and a portion of the orthographic projection of the first data line D1 onto the substrate 001 lies within the gap G4. For example, the portion of the orthographic projection of the first data line D1 onto the substrate 001 overlaps with the orthographic projection of the second electrode portion 132 onto the substrate 001. The orthographic projection of the first data line D1 onto the substrate 001 and the orthographic projection of the first electrode portion 131 onto the substrate 001 have a first overlapping area, and the orthographic projection of the first data line D1 onto the substrate 001 and the orthographic projection of the second electrode portion 132 onto the substrate 001 have a second overlapping area. The first overlapping area is smaller than the second overlapping area. For example, the first overlapping area can be 3% to 30% of the second overlapping area, but is not limited thereto.

[0128] This configuration allows the first data line to be located within the aforementioned interval G4 as much as possible, thereby reducing the coupling capacitance between the first data line and the first electrode or between the first data line and the second electrode, thus reducing the risk of dark spots.

[0129] Figure 11 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 12 is a partial layout view corresponding to the display panel in Figure 11.

[0130] For example, as shown in Figure 11, the difference between this display panel and the display panel shown in Figure 3 is that the repeating unit 1000 is different. The rest of the structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0131] For example, as shown in Figures 11 and 12, the plurality of repeating units 1000 in the display panel include a first type repeating unit 1010 and a second type repeating unit 1020, and the first type repeating unit 1010 and the second type repeating unit 1020 are arranged sequentially along the second direction Y. For example, the first type repeating unit 1010 and the second type repeating unit 1020 each include a third color sub-pixel 130. For example, the first electrode 101 of the third color sub-pixel 130 in the first type repeating unit 1010 and the second type repeating unit 1020 has a different projected area on the substrate 001, but the rest of the structure is the same.

[0132] For example, as shown in Figures 11 and 12, the difference between any of the first type repeating unit 1010 and the second type repeating unit 1020 and the repeating unit 1000 in Figure 9 lies in the difference in the third color sub-pixel 130. For example, the first electrode portion 131 of any of the first type repeating unit 1010 and the second type repeating unit 1020 includes a first sub-electrode portion 1311 and a second sub-electrode portion 1312 spaced apart along the second direction Y, and the orthographic projections of the first sub-electrode portion 1311 and the second sub-electrode portion 1312 in the first type repeating unit 1010 on the substrate 001 are different from the orthographic projections of the first sub-electrode portion 1311 and the second sub-electrode portion 1312 in the second type repeating unit 1020 on the substrate 001. For example, the orthographic projection areas are different, and the orthographic projection shapes are different, but the embodiments of this disclosure do not limit this. For example, the orthographic projection of one of the first sub-electrode portion 1311 and the second sub-electrode portion 1312 in the first type repeating unit 1010 onto the substrate 001 can be the same as the orthographic projection of one of the first sub-electrode portion 1311 and the second sub-electrode portion 1312 in the second type repeating unit 1020 onto the substrate 001.

[0133] For example, as shown in Figures 11 and 12, the orthographic projections of the first sub-electrode portion 1311 in the first type repeating unit 1010, the second sub-electrode portion 1312 in the first type repeating unit 1010, the first sub-electrode portion 1311 in the second type repeating unit 1020, and the second sub-electrode portion 1312 in the second type repeating unit 1020 on the substrate 001 are all different, and correspond to a mask opening for fabricating a light-emitting functional layer extending along the second direction Y. For example, the orthographic projections of the second electrode portion 132 in the first type repeating unit 1010 and the second electrode portion 132 in the second type repeating unit 1020 on the substrate 001 are the same, but the embodiments of this disclosure are not limited to this. For example, the second electrode portion 132 in the first type repeating unit 1010 and the second electrode portion 132 in the second type repeating unit 1020 may each correspond to a mask opening of a light-emitting functional layer. For example, the fabrication mask for the light-emitting functional layer corresponding to the two third color sub-pixels 130 in the first type repeating unit 1010 and the second type repeating unit 1020 adjacent in the second direction Y has three openings.

[0134] This configuration helps to reduce the risk of dark spots by avoiding overly concentrated placement of the first electrodes of the third color sub-pixels, and also facilitates the enlargement of the pixel aperture corresponding to the third color sub-pixels, increasing their pixel aperture ratio. Simultaneously, under this scheme, the first electrode of the third color sub-pixels can avoid the connection vias corresponding to the sub-pixels in the first region, ensuring the flatness of the first electrode. Furthermore, it minimizes overlap with data lines, thereby reducing the load on the data lines and decreasing the parasitic capacitance between the data lines and the first electrode. This improves display uniformity and facilitates high-frequency display implementation.

[0135] For example, as shown in Figures 11 and 12, the second electrode portion 132 includes a third sub-electrode portion 1313 and a fourth sub-electrode portion 1314 spaced apart in the first direction X. The first electrode 101 of the third color sub-pixel 130 also includes a second connecting electrode 142 connecting the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. For example, the orthographic projections of the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 on the substrate 001 are both rectangular, but their areas are different. This is not a limitation of the embodiments disclosed herein. In the second direction Y, the size of the second connecting electrode 142 is smaller than the size of the third sub-electrode portion 1313 and smaller than the size of the fourth sub-electrode portion 1314.

[0136] For example, as shown in FIG12, the first electrode portion 131 in the first type repeating unit 1010 and the first electrode portion 131 in the second type repeating unit 1020 both have a small overlap with the first data line D1. For example, the plurality of specific data lines D0 also include a second data line D2, at least a portion of the orthographic projection of the second data line D2 on the substrate 001 is located in the interval G5 between the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. For example, the orthographic projections of the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 on the substrate 001 do not overlap with the orthographic projection of the second data line D2 on the substrate 001, and the orthographic projection of the second connecting electrode 142 on the substrate 001 at least partially overlaps with the orthographic projection of the second data line D2 on the substrate 001.

[0137] This configuration reduces the coupling capacitance between the first and second electrode portions in each repeating unit and the second data line, and by dividing the first or second electrode portion into multiple sub-electrode portions, it helps to reduce the risk of dark spots.

[0138] In some embodiments, referring to FIG11 and FIG12, the first electrode 101 of the third color sub-pixel 130 in the first type repeating unit 1010 can also be connected to the first electrode 101 of the third color sub-pixel 130 in the second type repeating unit 1020 through a conductive structure.

[0139] Figure 13 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 14 is a partial layout view corresponding to the display panel in Figure 13.

[0140] For example, as shown in Figure 13, the main difference between this display panel and the display panel shown in Figure 3 is that the third color sub-pixel 130 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0141] For example, as shown in Figures 13 and 14, the repeating unit 1000 includes two third-color sub-pixels 130, and the first electrode portion 131 and the second electrode portion 132 are respectively the first electrodes 101 of the two third-color sub-pixels 130. For example, the first electrode portion 131 extends along the second direction Y, and the second electrode portion 132 extends along the first direction X, and the first electrode portion 131 and the second electrode portion 132 are spaced apart in the first direction X. For example, the first electrode portion 131 and the second electrode portion 132 may correspond to the same mask opening for fabricating the light-emitting functional layer. For example, the orthographic projection of this mask opening on the substrate 001 is "L"-shaped, which is beneficial to increasing the pixel aperture ratio. In some embodiments, the first electrode portion 131 and the second electrode portion 132 may also each correspond to a mask opening for fabricating the light-emitting functional layer, and the embodiments of this disclosure are not limited thereto.

[0142] For example, as shown in Figures 13 and 14, in the second direction Y, the sub-pixels 100 in the first region 010 and the second region 020, as well as the connection vias N corresponding to the first electrode portion 131, are all located on the side away from the second electrode portion 132 where the pixel opening 210 corresponding to the sub-pixel 100 in the second region 020 is located, and the connection vias N corresponding to the second electrode portion 132 are located on the side away from the first electrode portion 131 of the pixel opening 210 corresponding to the second electrode portion 132. For example, the first electrode 101 of the sub-pixel 100 (in this embodiment, the second color sub-pixel 120) near the second electrode portion 132 in the first region 010 in the second direction Y includes an extension portion 1201. At least a portion of the extension portion 1201 is located in the first direction X between the first electrode 101 and the first electrode portion 131 of the first color sub-pixel 110 in the first region 010, thereby enabling connection with the corresponding connection via N. For example, in the second direction Y, the corresponding connection via N of the second electrode portion 132 at least partially overlaps with the sub-pixel 100 (in this embodiment, the second color sub-pixel 120) in the second region 020 that is far from the first electrode portion 131, thereby helping to reduce the size of the repeating unit in the first direction X and saving layout space.

[0143] Figure 15 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure.

[0144] For example, as shown in Figure 15, the difference between this display panel and the display panel shown in Figure 13 is that the second area 020 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0145] For example, as shown in FIG15, the first color sub-pixel 110 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same row, the second color sub-pixel 120 in the first region 010 and the second electrode portion 132 are located in the same row, and the first electrode 101 of the first color sub-pixel 110 in the second region 020 is further away from the first electrode portion 131 in the first direction X than the first electrode 101 of the second color sub-pixel 120. For example, the display panel includes a first repeating unit 1001 and a second repeating unit 1002 that are adjacent in the first direction X, and the first color sub-pixel 110 in the second region 020 of the first repeating unit 1001 and the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002 are adjacent to each other in the first direction X.

[0146] This configuration allows the light-emitting functional layer of the first color sub-pixel in the second region of the first repeating unit and the light-emitting functional layer of the first color sub-pixel in the first region of the second repeating unit to share a mask opening, thereby increasing the setting range of the light-emitting functional layers of the two first color sub-pixels, simplifying the manufacturing process, and thus increasing the pixel aperture ratio.

[0147] Figure 16 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 17 is a partial layout view corresponding to the display panel in Figure 16.

[0148] For example, as shown in Figures 16 and 17, the difference between this display panel and the display panels shown in Figures 13 and 14 is that the third color sub-pixel 130 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0149] For example, as shown in Figures 16 and 17, at least one of the first electrode portion 131 and the second electrode portion 132 each includes a plurality of interconnected sub-electrode portions 1310, with a gap between at least two adjacent sub-electrode portions 1310, and at least a portion of a specific data line D0 located within the gap. For example, the specific data line D0 may be located between adjacent sub-electrode portions 1310, thereby reducing the coupling capacitance between each sub-electrode portion 1310 and lowering the risk of crosstalk.

[0150] For example, as shown in Figures 16 and 17, multiple specific data lines D0 include a third data line D3 and a fourth data line D4, which are arranged sequentially in the first direction X. For example, both the first electrode portion 131 and the second electrode portion 132 include multiple sub-electrode portions 1310. In the first electrode portion 131, there is a first interval G3 between adjacent sub-electrode portions 1310, and in the second electrode portion 132, there is a second interval G4 between adjacent sub-electrode portions 1310. At least a portion of the orthographic projection of the third data line D3 onto the substrate 001 is located within the first interval G3, and at least a portion of the orthographic projection of the fourth data line D4 onto the substrate 001 is located within the second interval G4.

[0151] For example, as shown in Figures 16 and 17, the orthographic projection of the third data line D3 on the substrate 001 may not overlap completely with the orthographic projection of the sub-electrode portion 1310 in the first electrode portion 131 on the substrate 001, or may only partially overlap. This reduces the coupling capacitance and lowers the risk of crosstalk. Similarly, the orthographic projection of the fourth data line D4 on the substrate 001 may not overlap completely with the orthographic projection of the sub-electrode portion 1310 in the second electrode portion 132 on the substrate 001, or may only partially overlap. This reduces the coupling capacitance and lowers the risk of crosstalk. The embodiments of this disclosure do not limit the shape of the orthographic projection of each sub-electrode portion 1310 in the first electrode portion 131 and the second electrode portion 132 on the substrate 001.

[0152] For example, as shown in Figures 16 and 17, the first electrode portion 131 includes a first sub-electrode portion 1311 and a second sub-electrode portion 1312 arranged at intervals along a first direction X. The first electrode 101 of the third color sub-pixel 130 also includes a first connecting electrode 141 connecting the first sub-electrode portion 1311 and the second sub-electrode portion 1312. At least a portion of the orthographic projection of the third data line D3 onto the substrate 001 is located between the first sub-electrode portion 1311 and the second sub-electrode portion 1312. For example, both the first sub-electrode portion 1311 and the second sub-electrode portion 1312 extend along a second direction Y, and the adjacent ends of the first sub-electrode portion 1311 and the second sub-electrode portion 1312 are connected by the first connecting electrode 141. The orthographic projections of the first sub-electrode portion 1311 and the second sub-electrode portion 1312 on the substrate 001 do not overlap with the orthographic projection of the third data line D3 on the substrate 001. Furthermore, the overlap area between the orthographic projection of the first connecting electrode 141 on the substrate 001 and the orthographic projection of the third data line D3 on the substrate 001 is small, thereby reducing the coupling capacitance and lowering the risk of crosstalk.

[0153] For example, as shown in Figures 16 and 17, the second electrode portion 132 includes a third sub-electrode portion 1313 and a fourth sub-electrode portion 1314 arranged at intervals along the first direction X. The first electrode 101 of the third color sub-pixel 130 also includes a second connecting electrode 142 connecting the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. At least a portion of the orthographic projection of the fourth data line D4 onto the substrate 001 is located between the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. For example, both the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 extend along the second direction Y, and the adjacent ends of the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 are connected by the second connecting electrode 142. The orthographic projections of the third sub-electrode 1313 and the fourth sub-electrode 1314 on the substrate 001 do not overlap with the orthographic projection of the fourth data line D4 on the substrate 001. Furthermore, the overlap area between the orthographic projection of the second connecting electrode 142 on the substrate 001 and the orthographic projection of the fourth data line D4 on the substrate 001 is small, thereby reducing the coupling capacitance and lowering the risk of crosstalk.

[0154] Figure 18 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure.

[0155] For example, as shown in Figure 18, the difference between this display panel and the display panel shown in Figure 16 is that the second area 020 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0156] For example, as shown in FIG18, the first color sub-pixel 110 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same row, the second color sub-pixel 120 in the first region 010 and the second electrode portion 132 are located in the same row, and the first electrode 101 of the first color sub-pixel 110 in the second region 020 is further away from the first electrode portion 131 in the first direction X than the first electrode 101 of the second color sub-pixel 120. For example, the display panel includes a first repeating unit 1001 and a second repeating unit 1002 that are adjacent in the first direction X, and the first color sub-pixel 110 in the second region 020 of the first repeating unit 1001 and the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002 are adjacent to each other in the first direction X.

[0157] This configuration allows the light-emitting functional layer of the first color sub-pixel in the second region of the first repeating unit and the light-emitting functional layer of the first color sub-pixel in the first region of the second repeating unit to share a mask opening, thereby increasing the setting range of the light-emitting functional layers of the two first color sub-pixels, simplifying the manufacturing process, and thus increasing the pixel aperture ratio.

[0158] Figure 19 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 20 is a partial layout view corresponding to the display panel in Figure 19.

[0159] For example, as shown in Figures 19 and 20, the difference between this display panel and the display panels shown in Figures 16 and 17 is that the third color sub-pixel 130 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0160] For example, as shown in Figures 19 and 20, the first electrode portion 131 includes a first sub-electrode portion 1311 and a second sub-electrode portion 1312 arranged at intervals along the second direction Y. The first electrode 101 of the third color sub-pixel 130 also includes a first connecting electrode 141 connecting the first sub-electrode portion 1311 and the second sub-electrode portion 1312. A portion of the orthographic projection of the third data line D3 on the substrate 001 is located between the first sub-electrode portion 1311 and the second sub-electrode portion 1312. The first connecting electrode 141 extends along the second direction Y and is spaced apart from the third data line D3, which helps to reduce the coupling capacitance between the first connecting electrode 141 and the third data line D3.

[0161] For example, as shown in Figures 19 and 20, the first sub-electrode portion 1311 extends along the first direction X, and the size of the first sub-electrode portion 1311 in the second direction Y is smaller than the size of the second sub-electrode portion 1312 in the second direction Y. This facilitates increasing the spacing between the first sub-electrode portion 1311 and the second sub-electrode portion 1312 in the second direction Y. As a result, a portion of the third data line D3 is exposed by this spacing, which helps to reduce the coupling capacitance between the third data line D3 and the first sub-electrode portion 1311, and also helps to reduce the coupling capacitance between the third data line D3 and the second sub-electrode portion 1312.

[0162] For example, as shown in Figures 19 and 20, the second electrode portion 132 includes a third sub-electrode portion 1313 and a fourth sub-electrode portion 1314 arranged at intervals along the first direction X. The first electrode 101 of the third color sub-pixel 130 also includes a second connecting electrode 142 connecting the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. The fourth data line D4 is located between the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. For example, both the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 extend along the second direction Y. The ends of the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 that are close to each other near the second region 020 are connected by the second connecting electrode 142. The ends of the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 that are far from the second region 020 are spaced apart from each other.

[0163] For example, as shown in Figures 19 and 20, the orthographic projections of the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 on the substrate 001 do not overlap with the orthographic projection of the fourth data line D4 on the substrate 001. Furthermore, the overlap area between the orthographic projection of the second connecting electrode 142 on the substrate 001 and the orthographic projection of the fourth data line D4 on the substrate 001 is further reduced (for example, compared to the display panel shown in Figure 17). This further reduces the coupling capacitance and lowers the risk of crosstalk.

[0164] Figure 21 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure.

[0165] For example, as shown in Figure 21, the difference between this display panel and the display panel shown in Figure 19 is that the second area 020 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0166] For example, as shown in FIG21, the first color sub-pixel 110 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same row, and the second color sub-pixel 120 in the first region 010 and the second electrode portion 132 are located in the same row. For example, the first electrode 101 of the first color sub-pixel 110 in the second region 020 is further away from the first electrode portion 131 in the first direction X than the first electrode 101 of the second color sub-pixel 120. For example, the display panel includes a first repeating unit 1001 and a second repeating unit 1002 that are adjacent in the first direction X, and the first color sub-pixel 110 in the second region 020 of the first repeating unit 1001 and the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002 are adjacent to each other in the first direction X.

[0167] This configuration allows the light-emitting functional layer of the first color sub-pixel in the second region of the first repeating unit and the light-emitting functional layer of the first color sub-pixel in the first region of the second repeating unit to share a mask opening, thereby increasing the setting range of the light-emitting functional layers of the two first color sub-pixels, simplifying the manufacturing process, and thus increasing the pixel aperture ratio.

[0168] Figure 22 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure; Figure 23 is a partial layout view corresponding to the display panel in Figure 22.

[0169] For example, as shown in Figures 22 and 23, the difference between this display panel and the display panels shown in Figures 19 and 20 is that the third color sub-pixel 130 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0170] For example, as shown in Figures 22 and 23, the first electrode 101 of the third color sub-pixel 130 further includes a first connecting electrode 141. The first electrode portion 131 includes a first sub-electrode portion 1311, a second sub-electrode portion 1312, a third sub-electrode portion 1313, and a fourth sub-electrode portion 1314 arranged in two rows and two columns and connected by the first connecting electrode 141. The first sub-electrode portion 1311 and the second sub-electrode portion 1312 are both located on the same side of the second electrode portion 132, and the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314 are both located in the same row as the second electrode portion 132. The third data line D3 is located between the first sub-electrode portion 1311 and the second sub-electrode portion 1312 in the first direction X.

[0171] For example, as shown in Figures 22 and 23, the orthographic projections of the first sub-electrode portion 1311, the second sub-electrode portion 1312, the third sub-electrode portion 1313, and the fourth sub-electrode portion 1314 on the substrate 001 may be different, and the embodiments of this disclosure do not limit this. For example, the first connecting electrode 141 includes a first sub-connecting electrode 1411, a second sub-connecting electrode 1412, and a third sub-connecting electrode 1413. The first sub-electrode portion 1311 is connected to the third sub-electrode portion 1313 through the first sub-connecting electrode 1411. The first sub-electrode portion 1311 is connected to the second sub-electrode portion 1312 through the second sub-connecting electrode 1412. The second sub-electrode portion 1312 is connected to the fourth sub-electrode portion 1314 through the third sub-connecting electrode 1413. The first sub-connecting electrode 1411 and the third sub-connecting electrode 1413 are both spaced apart from the third data line D3 in the first direction X. This can avoid the first electrode portion 131 from being too concentrated, thereby reducing the risk of dark spots, and can also reduce the coupling capacitance between the third data line D3 and the first connecting electrode 141, thereby reducing the coupling capacitance between the third data line D3 and the first electrode 101 of the third color sub-pixel 130.

[0172] For example, as shown in Figures 22 and 23, the second electrode portion 132 includes a fifth sub-electrode portion 1315 and a sixth sub-electrode portion 1316 spaced apart along the first direction X. The first electrode 101 of the third color sub-pixel 130 also includes a second connecting electrode 142 connecting the fifth sub-electrode portion 1315 and the sixth sub-electrode portion 1316. The fourth data line D4 is located between the third sub-electrode portion 1313 and the fourth sub-electrode portion 1314. For example, the fourth data line D4 does not overlap with either the third sub-electrode portion 1313 or the fourth sub-electrode portion 1314, thereby reducing the coupling capacitance. In the second direction Y, the size of the second connecting electrode 142 is smaller than the size of the portion of the fourth data line D4 located between the fifth sub-electrode portion 1315 and the sixth sub-electrode portion 1316, thus making the size of the overlapping portion of the second connecting electrode 142 and the fourth data line D4 smaller, which helps to reduce the coupling capacitance between the second connecting electrode 142 and the fourth data line D4. For example, the projected area of ​​the fifth sub-electrode portion 1315 on the substrate 001 is smaller than the projected area of ​​the sixth sub-electrode portion 1316 on the substrate 001, which helps to avoid the fifth sub-electrode portion 1315 being too concentrated, thereby reducing the risk of dark spots.

[0173] Figure 24 is a partial plan view of another display panel provided in at least one embodiment of the present disclosure.

[0174] For example, as shown in Figure 24, the difference between this display panel and the display panel shown in Figure 22 is that the second area 020 is different. The remaining structure and its corresponding technical effects can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0175] For example, as shown in FIG24, the first color sub-pixel 110 in the first region 010 and the sub-pixel 100 in the second region 020 are located in the same row, and the second color sub-pixel 120 in the first region 010 and the second electrode portion 132 are located in the same row. For example, the first electrode 101 of the first color sub-pixel 110 in the second region 020 is further away from the first electrode portion 131 in the first direction X than the first electrode 101 of the second color sub-pixel 120. For example, the display panel includes a first repeating unit 1001 and a second repeating unit 1002 that are adjacent in the first direction X, and the first color sub-pixel 110 in the second region 020 of the first repeating unit 1001 and the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002 are adjacent to each other in the first direction X.

[0176] This configuration allows the light-emitting functional layer of the first color sub-pixel in the second region of the first repeating unit and the light-emitting functional layer of the first color sub-pixel in the first region of the second repeating unit to share a mask opening, thereby increasing the setting range of the light-emitting functional layers of the two first color sub-pixels, simplifying the manufacturing process, and thus increasing the pixel aperture ratio.

[0177] For example, in some display panels provided by embodiments of this disclosure, multiple sub-pixels may be arranged in a standard red-green-blue (SRGB) pattern, but are not limited thereto.

[0178] At least one embodiment of this disclosure also provides another display panel.

[0179] As shown in Figures 3-4A, the display panel includes a plurality of sub-pixels 100. The plurality of sub-pixels 100 are divided into a plurality of repeating units 1000 (a sub-pixel within the dashed box 1000 in Figure 3 is a repeating unit). Each repeating unit 1000 includes a plurality of first-color sub-pixels 110, a plurality of second-color sub-pixels 120, and at least one third-color sub-pixel 130. For example, the first-color sub-pixel 110 can be a red sub-pixel, the second-color sub-pixel 120 can be a green sub-pixel, and the third-color sub-pixel 130 can be a blue sub-pixel, but is not limited thereto. The embodiments of this disclosure do not limit the emission color of the first-color sub-pixels 110, the second-color sub-pixels 120, and the third-color sub-pixels 130. For example, each repeating unit 1000 may include one third-color sub-pixel 120, or it may include a plurality of third-color sub-pixels 120.

[0180] As shown in Figures 3-4A, at least one third-color sub-pixel 130 in each repeating unit 1000 divides the repeating unit 1000 into two regions, each region containing at least one first-color sub-pixel 110 and at least one second-color sub-pixel 120. For example, the two regions can be a first region 010 and a second region 020. For example, the first region 010 may have one first-color sub-pixel 110 and one second-color sub-pixel 120, and the second region 020 may also have one first-color sub-pixel 110 and one second-color sub-pixel 120, but is not limited thereto. For example, the number of sub-pixels 100 in the first region 010 may be the same as or different from the number of sub-pixels 100 in the second region 020, and the embodiments of this disclosure do not limit this.

[0181] For example, as shown in Figures 3-4B, a repeating unit 100 may include at least two display units. For example, the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 in the first region 010 may correspond to one display unit, and the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 in the second region 020 may correspond to another display unit.

[0182] In the display panel provided by the embodiments of this disclosure, each repeating unit includes a plurality of first color sub-pixels, a plurality of second color sub-pixels, and at least one third color sub-pixel. This allows for a more compact arrangement of the multiple sub-pixels in the display panel, which is beneficial for increasing pixel density and making the display effect of the display panel clearer and more delicate. In addition, at least one third color sub-pixel divides the repeating unit into two regions, which is beneficial for at least one first color sub-pixel and at least one second color sub-pixel in each region to correspond to the same display unit as the at least one third color sub-pixel. This is also beneficial for at least one third color sub-pixel in the repeating unit to share a mask opening when fabricating the light-emitting functional layer, thereby simplifying the manufacturing process and increasing the pixel aperture ratio while reasonably arranging the layout space.

[0183] For example, as shown in Figures 3 and 4A, the display panel includes a substrate 001 and a pixel defining pattern 200 located on the substrate 001. For example, a sub-pixel 100 includes a light-emitting functional layer (not shown), and a first electrode 101 and a second electrode (not shown) located on either side of the light-emitting functional layer in a direction perpendicular to the substrate 001. The first electrode 101 is located between at least a portion of the light-emitting functional layer and the substrate 001. For example, the sub-pixel 100 may include a tandem light-emitting element, such as a Tandem OLED, but embodiments of this disclosure are not limited thereto. In a direction perpendicular to the substrate 001, at least a portion of the pixel defining pattern 200 is located between the light-emitting functional layer and the first electrode 101. The pixel defining pattern 200 includes a pixel opening 210 and a pixel defining portion 220 located between adjacent pixel openings 210. The pixel opening 210 exposes at least a portion of the first electrode 101 to define the light-emitting area of ​​the sub-pixel 100. The light-emitting functional layer is disposed in contact with the first electrode 101 through the pixel opening 210. For example, the first electrode 101 and the second electrode 102 located on both sides of the light-emitting functional layer can drive the light-emitting functional layer located between them to emit light.

[0184] In embodiments of this disclosure, the light-emitting area of ​​a sub-pixel refers to the area where the sub-pixel effectively emits light, and the shape of the light-emitting area refers to a two-dimensional shape. For example, the shape of the light-emitting area may be the same as the shape of the orthographic projection of the portion of the first electrode exposed by the pixel opening onto the substrate.

[0185] For example, as shown in Figures 3-4B, the repeating unit 1000 is divided into two regions, which can be a first region 010 and a second region 020. For example, the first region 010 may have a light-emitting area of ​​a first color sub-pixel 110 and a light-emitting area of ​​a second color sub-pixel 120, and the second region 020 may also have a light-emitting area of ​​a first color sub-pixel 110 and a light-emitting area of ​​a second color sub-pixel 120, but is not limited thereto. For example, the number of light-emitting areas of sub-pixels 100 in the first region 010 may be the same as or different from the number of light-emitting areas of sub-pixels 100 in the second region 020, and the embodiments of this disclosure do not limit this.

[0186] For example, as shown in Figures 3 to 4B, at least one third color sub-pixel 130 in the repeating unit 1000 has multiple light-emitting areas. The light-emitting areas of a first color sub-pixel 110 and a second color sub-pixel 120 are arranged in the first area 010 along the second direction Y, and the light-emitting areas of another first color sub-pixel 110 and another second color sub-pixel 120 are arranged in the second area 020 along the first direction X.

[0187] As shown in Figures 3-4B, both the first direction X and the second direction Y are parallel to the substrate 001, and the first direction X intersects the second direction Y. For example, the first direction X is perpendicular to the second direction Y, but it is not limited to this.

[0188] Therefore, the light-emitting areas in the first region and the second region can share the light-emitting area of ​​the third color sub-pixel in the repeating unit, which is conducive to making the distribution of the light-emitting areas in the first region and the second region reasonable, saving layout space, and increasing the area of ​​each light-emitting area.

[0189] For example, as shown in Figures 3 to 4B, in the first direction X, one of the light-emitting areas of the first color sub-pixel 110 and the second color sub-pixel 120 in the first region 010 is located in the first row 0011 along with the light-emitting area of ​​the sub-pixel 100 in the second region 020, and the other of the light-emitting areas of the first color sub-pixel 110 and the second color sub-pixel 120 in the first region 010 is located in the second row 0012 along with the light-emitting area of ​​the third color sub-pixel 130 in the repeating unit 1000.

[0190] For example, as shown in Figures 3-4B, the luminous area of ​​the first color sub-pixel 110 in the first region 010 is located in the first row 0011, and the luminous area of ​​the second color sub-pixel 120 in the first region 010 is located in the second row 0012. In the first direction X, the luminous area of ​​the first color sub-pixel 110 in the second region 020 is farther away from the first region 010 than the luminous area of ​​the second color sub-pixel 120. For example, the luminous areas of each sub-pixel 100 in the second region 020 are all located in the first row 0011. For example, the third color sub-pixel 130 in the repeating unit 1000 has three luminous areas, and these three luminous areas are arranged in an "L" shape. For example, one of the three luminous areas is located in the first row 0011, and the other two of the three luminous areas are located in the second row 0012. For example, the luminous areas of the two third color sub-pixels 130 in the repeating unit 1000 are located in the same column in the second direction Y.

[0191] This configuration allows the light-emitting areas of multiple repeating units to be distributed across two rows, which is beneficial for making reasonable use of the layout space and for enabling the light-emitting areas of the third color sub-pixels to be shared, thereby increasing pixel density and improving the display effect of the display panel.

[0192] For example, as shown in Figures 3-4B, the third color sub-pixel 130 in the repeating unit 1000 has at least one first light-emitting area and at least one second light-emitting area, wherein the at least one first light-emitting area is located in the first row 0011 and the at least one second light-emitting area is located in the second row 0012. The first light-emitting area is defined by a first pixel opening 2101 and the second light-emitting area is defined by a second pixel opening 2102.

[0193] For example, as shown in Figures 3 to 4B, at least one first light-emitting area is located between the first area 010 and the second area 020 in the first direction X, and at least one second light-emitting area is located on the side of the first area 010 closer to the second area 020.

[0194] This configuration allows the third color sub-pixel to have multiple light-emitting areas distributed at different locations, which is beneficial for the multiple light-emitting areas of the third color sub-pixel to form display units with the light-emitting areas in the first and second areas respectively, thereby improving the display effect.

[0195] For example, as shown in Figures 3, 7, 11, and 19, at least one first luminous region of the third color sub-pixel 130 in the repeating unit 1000 includes one first luminous region, and at least one second luminous region includes at least two second luminous regions. For example, the at least two second luminous regions include a specific second luminous region that is located in the same column as the first luminous region in the second direction Y, and the remaining second luminous regions of the at least two second luminous regions, excluding the specific second luminous region, are farther away from the first region 010 than the specific second luminous region. The specific second luminous region is defined by a specific pixel opening 21020.

[0196] For example, as shown in Figures 3 and 7, the third color sub-pixel 130 in the repeating unit 1000 includes one second light-emitting area other than the specific second light-emitting area. For example, as shown in Figures 11 and 19, the third color sub-pixel 130 in the repeating unit 1000 includes at least two second light-emitting areas other than the specific second light-emitting area, and these two light-emitting areas are spaced apart in the first row 0011. For example, the light-emitting areas of the first and second light-emitting areas of the third color sub-pixel 130 may be different. For example, the light-emitting areas of multiple second light-emitting areas may also be different; the embodiments of this disclosure do not limit the number or area of ​​the second light-emitting areas.

[0197] This configuration facilitates the rational distribution of multiple light-emitting areas of the third color sub-pixel and expands the light-emitting area of ​​the light-emitting area, thereby enabling high-frequency display.

[0198] For example, as shown in Figures 22 and 23, at least one first light-emitting area includes two first light-emitting areas, and at least one second light-emitting area includes four second light-emitting areas, with the two second light-emitting areas closest to the first area arranged in two rows and two columns with the two first light-emitting areas. For example, the third color sub-pixel in the repeating unit 1000 overlaps with four third pixel openings 2103 and two fourth pixel openings 2104. The fourth pixel openings 2104 are farther from the first area 010 in the first direction X than the third pixel openings 2103. For example, the four third pixel openings 2103 are arranged in two rows and two columns. For example, the two third pixel openings 2103 located in the first row 0011 of the above four third pixel openings 2103 define the two first light-emitting areas, and the two third pixel openings 2103 located in the second row 0012 of the above four third pixel openings 2103 define the two second light-emitting areas closest to the first area. For the arrangement of the light-emitting areas in the first and second areas, please refer to the relevant description of Figure 3 in the above embodiments, which will not be repeated here.

[0199] By increasing the number of multiple light-emitting areas corresponding to the third color sub-pixel and distributing these multiple light-emitting areas in different positions, it is possible to expand the total light-emitting area while simultaneously achieving high-frequency display effects.

[0200] For example, as shown in Figures 13 and 16, the plurality of light-emitting areas of the third color sub-pixel 130 in the repeating unit 1000 include at least one first light-emitting area and at least one second light-emitting area. For example, at least one first light-emitting area is located between the first region 010 and the second region 020 in the first direction X, and at least one second light-emitting area is located in the second row 0012, and at least one second light-emitting area is farther away from the first region 010 than at least one first light-emitting area. For example, the first light-emitting area overlaps with each light-emitting area in the first region 010 in the first direction X. For example, the third color sub-pixel 130 in the repeating unit 1000 corresponds to a third pixel opening 2103 and a fourth pixel opening 2104, the third pixel opening 2103 defining the first light-emitting area and the fourth pixel opening 2104 defining the second light-emitting area.

[0201] For example, as shown in Figure 13, the multiple light-emitting areas of the third color sub-pixel 130 in the repeating unit 1000 include a first light-emitting area and a second light-emitting area. The first light-emitting area extends along the second direction Y, and the second light-emitting area extends along the first direction X. The second light-emitting area overlaps with each light-emitting area in the second region 020 in the second direction Y. For example, as shown in Figure 13, both the first light-emitting area and the second light-emitting area are rectangular, but not limited to this.

[0202] This facilitates expanding the luminous area of ​​the third color sub-pixel, thereby increasing the luminous area. For the arrangement of the luminous areas in the first and second regions, please refer to the relevant description in Figure 3 of the above embodiments; it will not be repeated here.

[0203] For example, as shown in Figure 16, the plurality of light-emitting areas of at least one third color sub-pixel 130 in the repeating unit 1000 include a plurality of first light-emitting areas and a plurality of second light-emitting areas. Each first light-emitting area extends along the second direction Y, and the plurality of first light-emitting areas are spaced apart along the first direction X. The first light-emitting areas overlap with each light-emitting area in the first region 010 in the first direction X. The plurality of second light-emitting areas are spaced apart along the first direction X, and the second light-emitting areas overlap with at least one light-emitting area in the second region 020 in the second direction Y. For example, the third color sub-pixel 130 in the repeating unit 1000 corresponds to a plurality of third pixel openings 2103 and a plurality of fourth pixel openings 2104. The third pixel openings 2103 define the first light-emitting areas, and the fourth pixel openings 2104 define the second light-emitting areas.

[0204] For example, as shown in Figure 16, the size of the first light-emitting area in the second direction Y is larger than the size of the second light-emitting area in the second direction Y. Multiple first light-emitting areas are arranged at intervals along the first direction X, with a portion of the first light-emitting areas located in the first row 0011 and another portion located in the second row 0012. Multiple second light-emitting areas are located in the second row 0012 and are arranged at intervals. For details regarding the arrangement of the light-emitting areas in the first and second areas, please refer to the relevant description of Figure 3 in the above embodiments; it will not be repeated here.

[0205] By increasing the number of light-emitting areas and distributing them in different locations, the light-emitting area of ​​the third color sub-pixel can be maximized while enhancing the display effect of the display panel.

[0206] In embodiments of this disclosure, the display panel further includes a pixel driving structure, where different light-emitting areas can be independently driven by their respective pixel driving structures to emit light. For example, different light-emitting areas can also share a single pixel driving structure. For example, at least a portion of the first electrode of a sub-pixel can be exposed by multiple pixel openings to define multiple light-emitting areas, and the first electrode can be part of a pixel driving structure. For example, at least a portion of the first electrode of a sub-pixel can be exposed by a pixel opening to define a light-emitting area, and the first electrode can be part of a pixel driving structure. Embodiments of this disclosure do not limit the pixel driving structure corresponding to the light-emitting area of ​​a sub-pixel.

[0207] At least one embodiment of this disclosure also provides yet another display panel.

[0208] As shown in Figures 3 to 4B, the display panel includes a substrate 001 and a plurality of sub-pixels 100 located on the substrate 001. Each sub-pixel 100 includes a light-emitting functional layer (not shown in the figure), and a first electrode 101 and a second electrode (not shown in the figure) located on both sides of the light-emitting functional layer in a direction perpendicular to the substrate 001. The first electrode 101 is located between at least a portion of the light-emitting functional layer and the substrate 001.

[0209] For example, as shown in Figures 3-4B, the light-emitting functional layer includes multiple film layers. For example, the light-emitting functional layer may include a light-emitting layer for emitting light and a charge-generating layer. The charge-generating layer has strong conductivity, which enables the light-emitting functional layer to have advantages such as long lifespan, low power consumption, and high brightness. For example, the light-emitting functional layer can be a film layer in an organic light-emitting element. For example, the light-emitting functional layer may include a first light-emitting layer (EML), a charge-generating layer (CGL), and a second light-emitting layer (EML) stacked together, with the charge-generating layer located between the first and second light-emitting layers. It should be noted that the light-emitting functional layer shown in Figure 3 may also include other film layers, such as a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL), etc., and the embodiments of this disclosure are not limited to these. For example, the hole injection layer, hole transport layer, electron transport layer, electron injection layer, charge-generating layer, and second electrode are all common film layers of multiple sub-pixels 100, which can be called common layers.

[0210] For example, as shown in FIG3, subpixel 100 may include a tandem light-emitting element, such as a tandem OLED, but embodiments of this disclosure are not limited thereto.

[0211] For example, as shown in Figure 4, the display panel may also include a pixel driving circuit, which may be connected to the first electrode 101 to drive the light-emitting functional layer to emit light.

[0212] As shown in Figures 3-4B, the display panel further includes a pixel defining pattern 200. At least a portion of the pixel defining pattern 200 is located between the light-emitting functional layer and the first electrode 101 in a direction perpendicular to the substrate 001. The pixel defining pattern 200 includes a pixel opening 210 and a pixel defining portion 220 located between adjacent pixel openings 210. The pixel opening 210 exposes at least a portion of the first electrode 101 to define the light-emitting area of ​​the sub-pixel 100. The light-emitting functional layer is disposed in contact with the first electrode 101 through the pixel opening 210. For example, the first electrode 101 and the second electrode 102 located on either side of the light-emitting functional layer can drive the light-emitting functional layer located between them to emit light.

[0213] In embodiments of this disclosure, the light-emitting area of ​​a sub-pixel refers to the area where the sub-pixel effectively emits light, and the shape of the light-emitting area refers to a two-dimensional shape. For example, the shape of the light-emitting area may be the same as the shape of the orthographic projection of the portion of the first electrode exposed by the pixel opening onto the substrate.

[0214] As shown in Figures 3-4B, multiple sub-pixels 100 are divided into multiple repeating units 1000 (the sub-pixels within the dashed boxes 1000 in Figure 3 constitute one repeating unit). Each repeating unit 1000 includes multiple first-color sub-pixels 110, multiple second-color sub-pixels 120, and at least one third-color sub-pixel 130. For example, the first-color sub-pixel 110 can be a red sub-pixel, the second-color sub-pixel 120 can be a green sub-pixel, and the third-color sub-pixel 130 can be a blue sub-pixel, but is not limited thereto. The embodiments of this disclosure do not limit the emission color of the first-color sub-pixels 110, the second-color sub-pixels 120, and the third-color sub-pixels 130. For example, each repeating unit 1000 may include one third-color sub-pixel 120, or it may include multiple third-color sub-pixels 120. For example, the first electrode 101 of the third color sub-pixel 120 in each repeating unit 1000 can be a single-piece structure, corresponding to overlap with different pixel openings 210. The embodiments of this disclosure do not limit the number of third color sub-pixels 120 in the repeating unit 1000 or the number of light-emitting areas of the third color sub-pixels. In the embodiments of this disclosure, the overlap of the first electrode of a sub-pixel with a pixel opening means that at least a portion of the first electrode of the sub-pixel is exposed by the pixel opening to define a light-emitting area. For example, when the first electrode of a sub-pixel overlaps with one pixel opening, the sub-pixel has one light-emitting area. For example, when the first electrode of a sub-pixel overlaps with multiple different pixel openings, the sub-pixel has multiple light-emitting areas.

[0215] As shown in Figures 3-4B, the luminous area of ​​at least one third-color sub-pixel 130 in each repeating unit 1000 divides the repeating unit 1000 into two regions, each region containing at least one first-color sub-pixel 110 and at least one second-color sub-pixel 120. For example, the two regions can be a first region 010 and a second region 020. For example, the first region 010 may have a luminous area of ​​one first-color sub-pixel 110 and a luminous area of ​​one second-color sub-pixel 120, and the second region 020 may also have a luminous area of ​​one first-color sub-pixel 110 and a luminous area of ​​one second-color sub-pixel 120, but is not limited thereto. For example, the number of luminous areas of sub-pixels 100 in the first region 010 may be the same as or different from the number of luminous areas of sub-pixels 100 in the second region 020, and the embodiments of this disclosure do not limit this.

[0216] For example, as shown in Figures 3-4B, a repeating unit 100 may include at least two display units. For example, the light-emitting areas of the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 in the first region 010 may correspond to one display unit, and the light-emitting areas of the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 in the second region 020 may correspond to another display unit.

[0217] As shown in Figures 3-4B, both the first direction X and the second direction Y are parallel to the substrate 001, and the first direction X intersects the second direction Y. For example, the first direction X is perpendicular to the second direction Y, but it is not limited to this.

[0218] In the display panel provided by the embodiments of this disclosure, each repeating unit includes multiple first color sub-pixels, multiple second color sub-pixels, and at least one third color sub-pixel. This allows for a more compact arrangement of the multiple sub-pixels in the display panel, which is beneficial for increasing pixel density and making the display effect of the display panel clearer and more delicate. In addition, the light-emitting area of ​​at least one third color sub-pixel divides the repeating unit into two regions. This is beneficial for at least one first color sub-pixel and at least one second color sub-pixel in each region to correspond to the same display unit as the at least one third color sub-pixel. It is also beneficial for at least one third color sub-pixel in the repeating unit to share a mask opening when fabricating the light-emitting functional layer. This simplifies the manufacturing process and helps to increase the pixel aperture ratio while reasonably arranging the layout space.

[0219] For example, as shown in Figures 3 to 4B, a repeating unit 1000 may include three regions: a first region 010, a second region 020, and a third region 030 where the pixel opening 210 corresponding to the third color sub-pixel 130 in the repeating unit 1000 is located. The pixel opening 210 corresponding to the sub-pixel 100 in the third region 030 may be referred to as a "shared pixel opening".

[0220] For example, as shown in Figures 3 to 4B, at least one third color sub-pixel 130 in the repeating unit 1000 has multiple light-emitting areas. The light-emitting areas of a first color sub-pixel 110 and a second color sub-pixel 120 are arranged in the first area 010 along the second direction Y, and the light-emitting areas of another first color sub-pixel 110 and another second color sub-pixel 120 are arranged in the second area 020 along the first direction X.

[0221] For example, as shown in Figures 3-4B, the third color sub-pixel 130 in the repeating unit 1000 corresponds to three pixel openings 210. The first region 010 has two sub-pixels 100, namely a first color sub-pixel 110 and a second color sub-pixel 120, and the light-emitting areas of the first color sub-pixel 110 and the corresponding light-emitting areas of the second color sub-pixel 120 are spaced apart along the second direction Y in the first region 010. The second region 020 also has two sub-pixels 100, namely a first color sub-pixel 110 and a second color sub-pixel 120, and the light-emitting areas of the first color sub-pixel 110 and the second color sub-pixel 120 in the second region 020 are spaced apart along the first direction X. For example, the projected area or projected shape of the light-emitting areas of different color sub-pixels 100 on the substrate 001 is different.

[0222] Therefore, the light-emitting areas in the first region and the second region can share the light-emitting area of ​​the third color sub-pixel in the repeating unit, which is conducive to making the distribution of the light-emitting areas in the first region and the second region reasonable, saving layout space, and increasing the area of ​​each light-emitting area.

[0223] For example, as shown in Figures 3 to 4B, in the first direction X, one of the light-emitting areas of the first color sub-pixel 110 and the second color sub-pixel 120 in the first region 010 is located in the first row 0011 along with the light-emitting area of ​​the sub-pixel 100 in the second region 020, and the other of the light-emitting areas of the first color sub-pixel 110 and the second color sub-pixel 120 in the first region 010 is located in the second row 0012 along with the light-emitting area of ​​the third color sub-pixel 130 in the repeating unit 1000.

[0224] For example, as shown in Figures 3-4B, the light-emitting area of ​​the first color sub-pixel 110 in the first region 010 is located in the first row 0011, and the light-emitting area of ​​the second color sub-pixel 120 in the first region 010 is located in the second row 0012. The light-emitting areas of each sub-pixel 100 in the second region 020 are all located in the first row 0011. For example, the third color sub-pixel 130 in the repeating unit 1000 has three light-emitting areas, and these three light-emitting areas are arranged in an "L" shape. For example, one of the three light-emitting areas is located in the first row 0011, and the other two of the three light-emitting areas are located in the second row 0012. For example, the light-emitting areas of the two third color sub-pixels 130 in the repeating unit 1000 are located in the same column in the second direction Y.

[0225] This configuration allows the light-emitting areas of multiple repeating units to be distributed across two rows, which is beneficial for making reasonable use of the layout space and for enabling the light-emitting areas of the third color sub-pixels to be shared, thereby increasing pixel density and improving the display effect of the display panel.

[0226] For example, as shown in Figure 7, the arrangement of the light-emitting areas of the sub-pixels 100 in the second region 020 of the repeating unit 1000 of the display panel is different, while the arrangement of the light-emitting areas of the remaining sub-pixels 100 is the same as that of the display panel shown in Figure 3, and will not be described in detail here.

[0227] For example, as shown in Figure 7, the light-emitting area of ​​the first color sub-pixel 110 in the first region 010 is located in the first row 0011, and the light-emitting area of ​​the second color sub-pixel 120 in the first region 010 is located in the second row 0012. For example, in the first direction X, the light-emitting area of ​​the first color sub-pixel 110 in the second region 020 is farther away from the first region 010 than the light-emitting area of ​​the second color sub-pixel 120. For example, the display panel includes two adjacent repeating units in the first direction X, such as a first repeating unit 1001 and a second repeating unit 1002. For example, in the first direction X, the light-emitting area of ​​the first color sub-pixel 110 in the second region 020 of the first repeating unit 1001 is adjacent to the light-emitting area of ​​the first color sub-pixel 110 in the first region 010 of the second repeating unit 1002.

[0228] This configuration allows the light-emitting functional layers of the first color sub-pixels in the second region of the first repeating unit and the first color sub-pixels in the first region of the second repeating unit to share a common mask opening, thereby increasing the setting range of the light-emitting functional layers of the two first color sub-pixels and simplifying the manufacturing process, which in turn helps to increase the pixel aperture ratio.

[0229] For example, as shown in Figures 3-4B, the first electrode 101 of the third color sub-pixel 130 in the repeating unit 1000 is an integral structure, and the third color sub-pixel 130 has multiple light-emitting areas. For example, the third color sub-pixel 130 in the repeating unit 1000 has at least one first light-emitting area and at least one second light-emitting area, and the at least one first light-emitting area is located in the first row 0011, and the at least one second light-emitting area is located in the second row 0012. The first light-emitting area is defined by a first pixel opening 2101, and the second light-emitting area is defined by a second pixel opening 2102.

[0230] This configuration allows the third color sub-pixel to have multiple light-emitting areas distributed in different locations, which helps to concentrate the first electrode of the third color sub-pixel, thereby reducing the risk of generating dark spots.

[0231] For example, as shown in Figures 3, 7, and 11, at least two second light-emitting areas of the third color sub-pixel 130 in the repeating unit 1000 include a specific second light-emitting area, which is located in the same column as the first light-emitting area in the second direction Y, and the remaining second light-emitting areas of the at least two second light-emitting areas, excluding the specific second light-emitting area, are farther away from the first area 010 than the specific second light-emitting area. The specific second light-emitting area is defined by a specific pixel opening 21020.

[0232] For example, as shown in Figures 3 and 7, the third color sub-pixel 130 in the repeating unit 1000 has a first light-emitting area and two second light-emitting areas. The first light-emitting area and a specific second light-emitting area are located in the same column in the second direction Y, and the other of the two second light-emitting areas overlaps with the light-emitting area in the second region 020. For example, the two second light-emitting areas corresponding to the third color sub-pixel 130 are arranged adjacently in the second row 0012. For example, the second light-emitting area of ​​the third color sub-pixel 130 that overlaps with the light-emitting area in the second region 020 has a larger light-emitting area, and the orthogonal projection area of ​​this second light-emitting area on the substrate 001 is larger than the orthogonal projection area of ​​other light-emitting areas in the repeating unit 1000 on the substrate 001.

[0233] For example, as shown in FIG11, the third color sub-pixel 130 in the repeating unit 1000 has a first light-emitting area and three second light-emitting areas. The first light-emitting area and a specific second light-emitting area are located in the same column in the second direction Y, and the other two of the three second light-emitting areas are located on the side of the specific second light-emitting area away from the first area 010. For example, the three second light-emitting areas of the third color sub-pixel 130 are arranged adjacent to each other in the second row 0012. For example, the second light-emitting area of ​​the third color sub-pixel 130 that is farthest from the first area 010 in the first direction X has a larger opening area, and the orthogonal projection area of ​​this second light-emitting area on the substrate 001 is not less than the orthogonal projection area of ​​the other light-emitting areas in the repeating unit 1000 on the substrate 001.

[0234] This configuration, referring to Figures 4A, 8, and 12, helps to reduce the risk of dark spots while avoiding overly concentrated placement of the first electrodes of the third color sub-pixels. It also facilitates enlarging the pixel aperture corresponding to the third color sub-pixels, increasing their pixel aperture ratio. Furthermore, referring to Figure 12, it allows the pixel apertures corresponding to the third color sub-pixels to avoid obstructing the connection vias corresponding to the sub-pixels in the first region, ensuring the flatness of the first electrode. In addition, it minimizes overlap with data lines, thereby reducing the load on the data lines and decreasing the parasitic capacitance between the data lines and the first electrode. This improves display uniformity and facilitates high-frequency display.

[0235] For example, as shown in FIG10, the third color sub-pixel 130 in the repeating unit 1000 has a first light-emitting area and a second light-emitting area, at least partially overlapping the first light-emitting area in the second direction Y. For example, the repeating unit 1000 includes two pixel openings 210 located in the second row 0012. For example, the light-emitting area of ​​the second light-emitting area is larger than the light-emitting area of ​​the light-emitting areas of other sub-pixels 100 in the repeating unit 1000. For the arrangement of the light-emitting areas in the first and second areas, please refer to the relevant descriptions of FIG3 and FIG7 in the above embodiments, which will not be repeated here.

[0236] This setup avoids overly concentrated placement of the first electrode in the third color sub-pixel, reduces the risk of dark spots, and facilitates expanding the luminous area of ​​the second luminous region.

[0237] For example, as shown in Figures 13 and 14, the first electrode 101 of the third color sub-pixel 130 in the repeating unit 1000 includes a first electrode portion 131 and a second electrode portion 132. The second electrode portion 132 extends along a first direction X, and the first electrode portion 131 extends along a second direction Y, with the first electrode portion 131 and the second electrode portion 132 spaced apart from each other. For example, the repeating unit 1000 includes two third color sub-pixels 130, and the first electrode portion 131 and the second electrode portion 132 are respectively the first electrodes 101 of the two third color sub-pixels 130. For example, the first electrode portion 131 and the second electrode portion 132 may correspond to the same mask opening for fabricating a light-emitting functional layer. For example, the orthographic projection of this mask opening on the substrate 001 is "L"-shaped, which is beneficial for increasing the pixel aperture ratio. In some embodiments, the first electrode portion 131 and the second electrode portion 132 may also each correspond to a mask opening for fabricating a light-emitting functional layer, and the embodiments of this disclosure are not limited in this respect.

[0238] For example, as shown in Figures 13 and 14, the first electrode portion 131 and the second electrode portion 132 overlap with different pixel openings 210, and the pixel opening 210 overlapping with the second electrode portion 132 is located in the second row 0012. The pixel opening 210 corresponding to the first electrode portion 131 extends along the second direction Y, and the pixel opening 210 corresponding to the second electrode portion 132 extends along the first direction X.

[0239] This configuration avoids overly concentrated placement of the first electrode of the third color sub-pixel, reduces the risk of dark spots, further enlarges the pixel aperture corresponding to the third color sub-pixel, and increases the pixel aperture ratio.

[0240] For example, as shown in Figures 13 and 14, the first electrode portion 131 overlaps with a third pixel opening 2103, and the second electrode portion 132 overlaps with a fourth pixel opening 2104. The fourth pixel opening 2104 is further away from the first region 010 in the first direction X than the third pixel opening 2103. The third pixel opening 2103 extends along the second direction Y, and the fourth pixel opening 2104 extends along the first direction X. At least a portion of the third pixel opening 2103 overlaps with the fourth pixel opening 2104 in the first direction X. For example, the orthographic projections of the third pixel opening 2103 and the fourth pixel opening 2104 on the substrate 001 are both rectangular. This is beneficial for enlarging the pixel opening corresponding to the third color sub-pixel and increasing the pixel aperture ratio. For the arrangement of the pixel openings in the first and second regions, please refer to the relevant descriptions of Figures 3 and 7 in the above embodiments, which will not be repeated here.

[0241] For example, as shown in Figures 16 and 17, the first electrode portion 131 may overlap with a plurality of third pixel openings 2103, and the second electrode portion 132 may overlap with a plurality of fourth pixel openings 2104. The fourth pixel openings 2104 are further away from the first region 010 in the first direction X than the third pixel openings 2103. For example, the size of the third pixel openings 2103 in the second direction Y is larger than the size of the fourth pixel openings 2103 in the second direction Y. The plurality of third pixel openings 2103 are arranged at intervals along the first direction X, with a portion of the third pixel openings 2103 located in the first row 0011 and another portion located in the second row 0012. The plurality of fourth pixel openings 2104 are located in the second row 0012 and are arranged adjacent to each other. For the arrangement of the pixel openings in the first and second regions, please refer to the relevant descriptions of Figures 3 and 7 in the above embodiments, which will not be repeated here.

[0242] For example, as shown in Figures 16 and 17, at least a portion of the orthographic projection of the third data line D3 onto the substrate 001 lies between the orthographic projections of adjacent third pixel openings 2103 onto the substrate 001. At least a portion of the orthographic projection of the fourth data line D4 onto the substrate 001 lies between the orthographic projections of adjacent fourth pixel openings 2104 onto the substrate 001.

[0243] Therefore, the data line's influence on the light-emitting area of ​​the sub-pixel can, for example, result in good flatness of the light-emitting area and reduce the coupling capacitance between the first electrode of the third color sub-pixel and the data line, thereby reducing the risk of crosstalk.

[0244] For example, as shown in Figures 19 and 20, the first electrode portion 131 may overlap with two third pixel openings 2103, and the second electrode portion 132 may overlap with two fourth pixel openings 2104. The fourth pixel openings 2104 are further away from the first region 010 in the first direction X than the third pixel openings 2103. The two third pixel openings 2103 are arranged at intervals along the second direction Y, and are located in the first row 0011 and the second row 0012, respectively. For example, the two third pixel openings 2103 may have different opening areas, and the two fourth pixel openings 2104 may also have different opening areas. For example, one of the two third pixel openings 2103 may be located in the first row 0011, the other in the second row 0012, and both fourth pixel openings 2104 may be located in the second row 0012. For the arrangement of the pixel openings in the first and second regions, please refer to the relevant descriptions of Figures 3 and 7 in the above embodiments; they will not be repeated here.

[0245] By arranging the two third pixel openings spaced apart in the second direction, the overlap with signal lines (e.g., the third data lines) located between the third color sub-pixel and the substrate can be reduced; by arranging the two fourth pixel openings spaced apart in the first direction, the overlap with signal lines (e.g., the fourth data lines) located between the third color sub-pixel and the substrate can be reduced.

[0246] For example, as shown in Figures 22 and 23, the first electrode portion 131 overlaps with four third pixel openings 2103, and the second electrode portion 132 overlaps with two fourth pixel openings 2104. The fourth pixel openings 2104 are further away from the first region 010 in the first direction X than the third pixel openings 2103. For example, the four third pixel openings 2103 are arranged in two rows and two columns. For example, two of the four third pixel openings 2103 are located in the first row 0011, the other two of the four third pixel openings 2103 are located in the second row 0012, and both of the two fourth pixel openings 2104 are located in the second row 0012. For the arrangement of the pixel openings in the first and second regions, please refer to the relevant descriptions of Figures 3 and 7 in the above embodiments, which will not be repeated here.

[0247] This configuration can reduce the risk of dark spots by avoiding excessive concentration of the first electrode portion of the third color sub-pixel, while increasing the number of multiple pixel openings corresponding to the third color sub-pixel and distributing each pixel opening in different positions. This can reduce the influence of the signal line (e.g., the third data line mentioned above) between the third color sub-pixel and the substrate on each light-emitting area. For example, it can make the light-emitting area have good flatness, which is beneficial to improving the display effect.

[0248] It should be noted that the distribution of the multiple pixel openings corresponding to the third color sub-pixel in the embodiments of this disclosure is not limited to the distribution provided in the above embodiments. For example, they can have different distribution forms according to design needs, such as different setting positions according to the position of signal lines and vias in the display panel. For example, the overlap area with signal lines can be reduced, or a suitable distance can be maintained with vias, so as to ensure that the light-emitting area defined by the pixel opening has good flatness as much as possible. For example, the multiple pixel openings corresponding to the third color sub-pixel can have different shapes, etc., and the embodiments of this disclosure do not limit this.

[0249] For example, the display panel provided in the embodiments of this disclosure employs color filter on encapsulation (COE) technology to achieve good foldability and lifespan performance, as well as low power consumption. For example, the display panel provided in the embodiments of this disclosure is a medium to large-sized product. For example, the display panel provided in the embodiments of this disclosure can also employ maskless deposition and photolithography techniques; that is, the design principles mentioned in the above embodiments can also be applied to this technology, and are not limited to the use of fine metal mask (FMM) technology.

[0250] At least one embodiment of this disclosure also provides a display device, which includes a display panel provided in the embodiments of this disclosure (e.g., the display panel described in the above embodiments). Therefore, the technical effects of the aforementioned display panel can also be reflected in this display device, and will not be repeated here.

This embodiment is not limited to this.

[0254] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure may be combined with each other.
