[0026] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] This invention provides a display panel, as shown in FIG1, which is a top view of a display panel according to an embodiment of the present invention. The display panel 100 includes: a substrate 1; a plurality of first unit groups 10 and a plurality of second unit groups 20 located on the same side of the substrate 1, wherein the first unit groups 10 and the second unit groups 20 are alternately arranged in a first direction h11, the first unit group 10 including a plurality of first units U1 arranged along a second direction h12, the second direction h12 intersecting the first direction h11; the second unit group 20 including a plurality of second units U2 arranged along the second direction h12; wherein, both the first unit U1 and the second unit U2 include a plurality of sub-pixels, optionally including a first sub-pixel SP1, a second sub-pixel SP2 and a third sub-pixel SP3; for example, the emitted light colors of the first sub-pixel SP1, the second sub-pixel SP2 and the third sub-pixel SP3 are different from each other. When the display panel is displaying, the first unit U1 and the second unit U2 can both be displayed as a pixel unit, that is, the first unit U1 and the second unit U2 do not need to borrow sub-pixels from other pixel units for display.

[0031] For example, at least one of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 includes an arc edge in shape. It should be noted that, as shown in FIG2, which is a cross-sectional schematic diagram of a display panel provided in an embodiment of the present invention, the display panel further includes a pixel definition layer (PDL) 11. The sub-pixel SP includes a first electrode 01, a light-emitting layer 02, and a second electrode 03 stacked together. The pixel definition layer 11 includes a pixel opening 110, and at least a portion of the light-emitting layer 02 is located within the pixel opening 110. The shape of the sub-pixel SP mentioned in the embodiments of the present invention can be understood as the shape of the orthographic projection of the pixel opening 110 onto the plane of the substrate 1. For example, the shape of the first sub-pixel SP1 includes an arc edge, that is, the shape of the orthographic projection of the pixel opening 110 in the pixel definition layer 11 used to form the first sub-pixel SP1 onto the plane of the substrate 1 includes an arc edge.

[0032] In related technologies, subpixels are typically quadrilaterals or polygons with clearly defined equilateral corners. As shown in Figure 3, a schematic diagram of a display panel in related technologies, pixel unit U' includes a first subpixel SP1', a second subpixel SP2', and a third subpixel SP3', all of which are rectangular in shape. To reduce ambient light reflection and achieve a seamless black effect on the display panel, as shown in Figure 2, a light-shielding layer 40 is typically fabricated between adjacent subpixels SP. This light-shielding layer 40 is located on the light-emitting side of the subpixel SP, and the shape of the opening in the light-shielding layer 40 follows the shape of the subpixel SP. When the light-shielding layer 40 is fabricated between adjacent rectangular subpixels, the light emitted by the subpixel through the opening in the light-shielding layer 40 is equivalent to passing through a slit, resulting in a diffraction effect. This causes a series of alternating bright and dark stripes on the light-emitting surface of the display panel, affecting the display effect.

[0033] In this embodiment of the invention, by making at least one of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 circular in shape, when setting the light-shielding layer 40, the shape of the opening of the corresponding sub-pixel SP in the light-shielding layer 40 can also be circular, which can reduce the probability of diffraction effect when the sub-pixel SP emits light, avoid the appearance of stripes on the surface of the display panel 100, and improve the visual effect of the display panel 100.

[0034] Optionally, at least one of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may have a circular shape. That is, the shape of the pixel opening 110 corresponding to any one of the three may be circular. Figure 1 illustrates this with all three being circular. The circular setting can further reduce diffraction phenomena and improve the display effect of the display panel.

[0035] It should be noted that, considering process errors, the circular shapes of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 can be circles within the allowable range of process errors. For example, the actual shapes of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 can be circular or near-circular shapes similar to circles.

[0036] In this embodiment of the invention, as shown in FIG1, in the first unit U1, the first sub-pixel SP1 and the third sub-pixel SP3 are arranged along the first direction h11, and the second sub-pixel SP2 is located on one side of the first sub-pixel SP1 and the third sub-pixel SP3 along the second direction h12. In the second unit U2, the first sub-pixel SP1 and the third sub-pixel SP3 are arranged along the first direction h11, and the second sub-pixel SP2 is located on the other side of the first sub-pixel SP1 and the third sub-pixel SP3 along the second direction h12.

[0037] Taking the orientation shown in Figure 1 as an example, in the first unit U1, the second sub-pixel SP2 is located above the first sub-pixel SP1 and the second sub-pixel SP2 along the second direction h12. In the second unit U2, the second sub-pixel SP2 is located below the first sub-pixel SP1 and the second sub-pixel SP2 along the second direction h12.

[0038] Comparing with Figure 4, which is a schematic diagram of another display panel in the related technology, the multiple pixel units U” in the display panel are arranged in the same way. That is, in each pixel unit U”, the second sub-pixel SP2” is located on the same side of the first sub-pixel SP1” and the third sub-pixel SP3” along the second direction h12 (taking the orientation shown in Figure 4 as an example, the second sub-pixel SP2” is located below the first sub-pixel SP1” and the third sub-pixel SP3” along the second direction h12). It can be seen that there is a large amount of unused space around the second sub-pixel SP2”, resulting in a low space utilization rate of the display panel.

[0039] The arrangement method provided in this embodiment of the invention can, on the one hand, increase the arrangement types of pixel units in the display panel; on the other hand, it can also increase the area of ​​the settable space of each sub-pixel in the first unit U1 and the second unit U2, improve the space utilization of the display panel, and help to increase the area of ​​each sub-pixel in the first unit U1 and the second unit U2, increase the aperture ratio of the sub-pixels, thereby reducing the current density of the sub-pixels, improving the product life of the display panel, and reducing the power consumption of the display panel.

[0040] For example, the emitted light colors of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 are different from each other. For instance, the first sub-pixel SP1 includes a red sub-pixel that emits red light, the second sub-pixel SP2 includes a green sub-pixel that emits green light, and the third sub-pixel SP3 includes a blue sub-pixel that emits blue light.

[0041] Optionally, as shown in Figure 1, the area of ​​the first sub-pixel SP1 is less than or equal to the area of ​​the second sub-pixel SP2, the area of ​​the first sub-pixel SP1 is less than or equal to the area of ​​the third sub-pixel SP3, and the area of ​​the second sub-pixel SP2 is less than or equal to the area of ​​the third sub-pixel SP3. For example, the specific area of ​​each of the above sub-pixels can be set according to their respective luminous efficiency.

[0042] In the first unit U1 and the second unit U2, the embodiments of the present invention arrange the first sub-pixel SP1 and the third sub-pixel SP3 along the first direction h11 into a sub-pixel row, and arrange the second sub-pixel SP2 to form another sub-pixel row. By combining the area settings of each sub-pixel, the space occupied by the two sub-pixel rows in the first direction h11 can be balanced, which is beneficial to further improve the space utilization of the display panel and increase the aperture ratio of each sub-pixel.

[0043] For example, the area of ​​the first sub-pixel SP1 is S1, and the area of ​​the third sub-pixel SP3 is S3, where 1 / 6 ≤ S1 / S3 ≤ 1. Based on this setting, the areas of the first sub-pixel SP1 and the third sub-pixel SP3 can be matched with their respective luminous efficiencies.

[0044] Optionally, as shown in Figure 1, in adjacent first units U1 and second units U2 along the first direction h11, the second sub-pixels SP2 of the first unit U1 and the second sub-pixels SP2 of the second unit U2 do not overlap in the first direction h11. That is, the second sub-pixels SP2 of the first unit U1 and the second sub-pixels SP2 of the second unit U2 are staggered in the first direction h11. This arrangement allows the second sub-pixels SP2 of the first unit U1 and the second unit U2 to be dispersed, avoiding the concentration of second sub-pixels SP2 with large areas. This improves the space utilization in the first unit U1 and the second unit U2, and also allows the area of ​​the second sub-pixels SP2 to be set as large as possible, thereby increasing the pixel aperture ratio of the second sub-pixels SP2.

[0045] Optionally, as shown in Figure 1, in the first unit U1 and the second unit U2 adjacent along the first direction h11, the second sub-pixel SP2 in one of them can at least partially overlap with the first sub-pixel SP1 and the third sub-pixel SP2 in the other in the first direction h11.

[0046] For example, as shown in Figure 1, the geometric centers of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 are located at the three vertices of the virtual triangle DT1, respectively. The virtual triangle DT1 includes a first vertex α, and the geometric center of the second sub-pixel SP2 coincides with the vertex of the first vertex α. In this embodiment of the invention, the orientation of the first vertex α in the first unit U1 is opposite to that in the second unit U2. Figure 1 illustrates this with the first vertex α in the first unit U1 pointing upwards and the first vertex α in the second unit U2 pointing downwards. Based on this arrangement, the second sub-pixels SP2 in the first unit U1 and the second unit U2 can be distributed, which is beneficial for balancing the settable space of each sub-pixel in the first unit U1 and the second unit U2, thereby improving the space utilization of the display panel and increasing the area of ​​each sub-pixel, thus increasing the aperture ratio of the sub-pixels.

[0047] For example, in this embodiment of the invention, the shape of the sub-pixel SP can be a centrally symmetric shape or an axially symmetric shape with two or more axes of symmetry. For example, ellipses, parallelograms (not rectangles or rhombuses), circles, rounded rectangles, regular polygons, rectangles, and rhombuses are all regular shapes. For a centrally symmetric shape, its central symmetry point is the geometric center; for an axially symmetric shape with two or more axes of symmetry, the intersection of its two axes of symmetry is the geometric center. Alternatively, the shape of the sub-pixel in this embodiment of the invention can also be an irregular shape, and the geometric center of the irregular shape can be determined using related techniques.

[0048] Optionally, as shown in FIG2, the display panel 100 further includes an encapsulation layer 11, a light-shielding layer 40, and a color filter (CF) layer 30 located on the side of the sub-pixel SP away from the substrate 1. The light-shielding layer 40 may be located on the side of the encapsulation layer 11 away from the substrate 10. The light-shielding layer 40 includes a first opening 401 corresponding to the aforementioned pixel opening 110. The color filter layer 30 is at least partially located within the first opening 401. For example, the light-shielding layer 6 includes a black matrix (BM).

[0049] For example, as shown in FIG2, the color resist layer 30 includes a first color resist layer 301, a second color resist layer 302, and a third color resist layer (not shown in FIG2). Along the direction h2 perpendicular to the plane of the substrate 1, the first color resist layer 301 at least partially overlaps with the first sub-pixel SP1, the second color resist layer 302 at least partially overlaps with the second sub-pixel SP2, and the third color resist layer at least partially overlaps with the third sub-pixel. The light emitted from the sub-pixel SP passes through the corresponding color resist layer 30, which can improve the accuracy of the emitted color of the sub-pixel SP. In addition, the color resist layer 30 can also reduce the reflectivity of the display panel 100 by absorbing the incident ambient light. Moreover, based on this arrangement, the color resist layer 30 is equivalent to being reused as a polarizer, thereby eliminating the need to additionally provide a polarizer on the light-emitting side of the display panel 100, which is beneficial for reducing the thickness of the display panel 100.

[0050] For example, as shown in FIG2, the encapsulation layer 11 includes a first inorganic encapsulation layer 111, an organic encapsulation layer 112 and a second inorganic encapsulation layer 113 stacked together.

[0051] Optionally, as shown in Figure 1, in the adjacent first unit U1 and second unit U2 along the first direction h11, the geometric center of the first sub-pixel SP1 and the geometric center of the third sub-pixel SP3 in the first unit U1 are not on the same straight line as the geometric center of the second sub-pixel SP2 in the second unit U2. That is, the geometric center of the second sub-pixel SP2 in the second unit U2 is offset from the geometric centers of the first sub-pixel SP1 and the third sub-pixel SP3 in the first unit U1 along the first direction h11.

[0052] By adopting this setting method, at least a portion of the second sub-pixel SP2 in the second unit U2 can be set at a position that does not overlap with the first sub-pixel SP1 and the second sub-pixel SP2 in the first unit U1 along the first direction h11. Thus, while ensuring that other sub-pixels are not affected, the area of ​​the second sub-pixel SP2 in the second unit U2 can be set as large as possible, which is beneficial to increasing the pixel aperture ratio of the second sub-pixel SP2 in the second unit U2.

[0053] Optionally, as shown in Figure 1, in the adjacent first unit U1 and second unit U2 along the first direction h11, the geometric center of the first sub-pixel SP1 and the geometric center of the third sub-pixel SP3 in the second unit U2 are not on the same straight line as the geometric center of the second sub-pixel SP2 in the first unit U1. That is, the geometric center of the second sub-pixel SP2 in the first unit U1 is offset from the geometric centers of the first sub-pixel SP1 and the third sub-pixel SP3 in the second unit U2 along the first direction h11.

[0054] By adopting this setting method, at least a portion of the second sub-pixel SP2 in the first unit U1 can be set at a position that does not overlap with the first sub-pixel SP1 and the second sub-pixel SP2 in the second unit U2 along the first direction h11. Thus, while ensuring that other sub-pixels are not affected, the area of ​​the second sub-pixel SP2 in the first unit U1 can be set as large as possible, which is beneficial to increasing the pixel aperture ratio of the second sub-pixel SP2 in the first unit U1.

[0055] For example, in this embodiment of the invention, the areas of sub-pixels with the same emitted light color in the first unit U1 and the second unit U2 can be the same. That is, the areas of the first sub-pixel SP1 in the first unit U1 and the first sub-pixel SP1 in the second unit U2 are the same, the areas of the second sub-pixel SP2 in the first unit U1 and the second sub-pixel SP2 in the second unit U2 are the same, and the areas of the third sub-pixel SP3 in the first unit U1 and the third sub-pixel SP3 in the second unit U2 are the same. Optionally, one of the first unit U1 and the second unit U2 can be obtained by flipping them vertically.

[0056] Optionally, as shown in Figure 1, in the first unit group 10, the geometric centers of multiple first sub-pixels SP1 are located on the first virtual line DL1, the geometric centers of multiple second sub-pixels SP2 are located on the second virtual line DL2, and the geometric centers of multiple third sub-pixels SP3 are located on the fifth virtual line DL5. The first virtual line DL1 and the second virtual line DL2 do not intersect. The fifth virtual line DL5 and the second virtual line DL2 do not intersect.

[0057] For example, as shown in Figure 1, the first virtual line DL1, the second virtual line DL2 and the fifth virtual line DL5 can all extend along the second direction h12, and the three are staggered from each other.

[0058] Based on this configuration, the first sub-pixel SP1 and the second sub-pixel SP2 in the first unit U1 can be at least partially offset in the second direction h12, and the third sub-pixel SP3 and the second sub-pixel SP2 in the first unit U1 can be at least partially offset in the second direction h12. For example, in this embodiment of the invention, at least a portion of the second sub-pixel SP2 in the first unit U1 can be set to the gap position between the first sub-pixel SP1 and the third sub-pixel SP3. While avoiding affecting the setting space of the first sub-pixel SP1 or the third sub-pixel SP3, the area of ​​the second sub-pixel SP2 can be set as large as possible to increase the aperture ratio of the second sub-pixel SP2.

[0059] And / or, as shown in Figure 1, in the second unit group 20, the geometric centers of multiple first sub-pixels SP1 are located on the third virtual line DL3, the geometric centers of multiple second sub-pixels SP2 are located on the fourth virtual line DL4, and the geometric centers of multiple third sub-pixels SP3 are located on the sixth virtual line DL6. The third virtual line DL3 and the fourth virtual line DL4 do not intersect. The sixth virtual line DL6 and the fourth virtual line DL4 do not intersect.

[0060] For example, as shown in Figure 1, the third virtual line DL3, the fourth virtual line DL4 and the sixth virtual line DL6 can all extend along the second direction h12, and the three are staggered from each other.

[0061] Based on this configuration, the first sub-pixel SP1 and the second sub-pixel SP2 in the second unit U2 can be at least partially offset in the second direction h12, and the third sub-pixel SP3 and the second sub-pixel SP2 in the second unit U2 can be at least partially offset in the second direction h12. For example, in this embodiment of the invention, at least a portion of the second sub-pixel SP2 in the second unit U2 can be set to correspond to the gap position between the first sub-pixel SP1 and the third sub-pixel SP3. While avoiding affecting the setting space of the first sub-pixel SP1 or the third sub-pixel SP3, the area of ​​the second sub-pixel SP2 in the second unit U2 can be set as large as possible to increase the aperture ratio of the second sub-pixel SP2 in the second unit U2.

[0062] For example, as shown in Figure 1, the distance between the geometric centers of the two closest first sub-pixels SP1 on the first direction h11 is d11. As shown in Figure 1, one of the two closest first sub-pixels SP1 on the first direction h11 belongs to the first unit U1, and the other belongs to the second unit U2. The distance between the geometric centers of two adjacent first sub-pixels SP1 on the second direction h12 is d12. Two adjacent first sub-pixels SP1 on the second direction h12 can belong to two adjacent first units U1, or two adjacent second units U2. In this embodiment of the invention, d11 = d12. Based on this setting, the distribution of first sub-pixels SP1 in different directions can be more uniform, which is beneficial to improving the consistency of the display effect of the display panel in different directions.

[0063] And / or, as shown in Figure 1, the distance between the geometric centers of the two closest second sub-pixels SP2 on the first direction h11 is d21; for example, as shown in Figure 1, one of the two closest second sub-pixels SP2 on the first direction h11 belongs to the first unit U1 and the other belongs to the second unit U2. The distance between the geometric centers of two adjacent second sub-pixels SP2 on the second direction h12 is d22; for example, as shown in Figure 1, two adjacent second sub-pixels SP2 on the second direction h12 can belong to two adjacent first units U1, or to two adjacent second units U2. In this embodiment of the invention, d21 = d22. Based on this setting, the distribution of the second sub-pixels SP2 in different directions can be more uniform, which is beneficial to improving the consistency of the display effect of the display panel in different directions.

[0064] And / or, as shown in Figure 1, the distance between the geometric centers of the two closest third sub-pixels SP3 on the first direction h11 is d31. For example, as shown in Figure 1, one of the two closest third sub-pixels SP3 on the first direction h11 belongs to the first unit U1, and the other belongs to the second unit U2. The distance between the geometric centers of two adjacent third sub-pixels SP3 on the second direction h12 is d32. For example, as shown in Figure 1, two adjacent third sub-pixels SP3 on the second direction h12 can belong to two adjacent first units U1, or two adjacent second units U2. In this embodiment of the invention, d31 = d32. Based on this setting, the distribution of the third sub-pixels SP3 in different directions can be more uniform, which is beneficial to improving the consistency of the display effect of the display panel in different directions.

[0065] For example, when fabricating this display panel, as shown in Figure 2, a pixel opening 110 can be first created in the pixel definition layer 11, and then a light-emitting material can be deposited in the pixel opening 110 using a fine metal mask (FMM) with an opening to form a light-emitting layer 02. To balance process capability and improve product yield, for example, as shown in Figure 2, at least a portion of the light-emitting material can also be located outside the pixel opening 110. The area where the light-emitting material is expected to be deposited during the design process is defined as the target deposition area. Referring to Figure 5, which is a schematic diagram of a display panel including multiple sub-pixels with target deposition areas provided by an embodiment of the present invention, Figure 5 shows the target deposition areas of the light-emitting material with dashed lines. The display panel includes a first target deposition area 21 corresponding to the first sub-pixel SP1, a second target deposition area 22 corresponding to the second sub-pixel SP2, and a third target deposition area 23 corresponding to the third sub-pixel SP3. As shown in Figure 5, the area of ​​the target deposition area is slightly larger than the area of ​​the corresponding sub-pixel. The target deposition area and the corresponding sub-pixel can be concentric circles.

[0066] When the arrangement of multiple sub-pixels in the first unit U1 and the second unit U2 is set to be the same, as shown in Figure 4, the target vapor deposition area corresponding to the second sub-pixel SP2” and the surrounding multiple sub-pixels are spaced apart from the third target vapor deposition area 23” in another pixel unit U” adjacent to the pixel unit U” to which the second sub-pixel SP2” belongs in the second direction h12, resulting in a large amount of unused space in the display panel, which makes the space utilization rate of the display panel low.

[0067] For example, in an embodiment of the present invention, one of the first unit group 10 and the second unit group 20 includes a first sub-unit 101, and the other includes a second sub-unit 102 and a third sub-unit 103; FIG5 illustrates a portion of the first unit U1 in the first unit group 10 including the first sub-unit 101, and a portion of the second unit U2 in the second unit group 20 including the second sub-unit 102 and the third sub-unit 103, wherein the second sub-unit 102 and the third sub-unit 103 are arranged adjacent to each other in the second direction h12, and the third sub-unit 102 is arranged adjacent to the third sub-unit 103. Subunit 103 is located on the side of the first sub-pixel SP1 in the second subunit 102 away from the second sub-pixel SP2 (taking the orientation shown in Figure 5 as an example, the third subunit 103 is located below the second subunit 102); the first subunit 101 and the third subunit 103 are arranged adjacent to each other in the first direction h11, and the first subunit 101 is located on the side of the first sub-pixel SP1 of the third subunit 103 away from the third sub-pixel SP3 (taking the orientation shown in Figure 5 as an example, the first subunit 101 is located to the left of the third subunit 103).

[0068] As shown in Figure 5, the line connecting the geometric center of the third sub-pixel SP3 in the first sub-unit 101, the geometric center of the third sub-pixel SP3 in the second sub-unit 102, and the geometric center of the third sub-pixel SP3 in the third sub-unit 103 forms a first virtual inscribed triangle 31; the first virtual inscribed triangle 31 has a first virtual circumscribed circle 41.

[0069] In this embodiment of the invention, the center Q1 of the first virtual circumcircle 41 coincides with the geometric center O2_103 of the second sub-pixel SP2 in the third sub-unit 103. Based on this configuration, the second target vapor deposition area 22 corresponding to the second sub-pixel SP2 in the third sub-unit 103 can be made tangent to the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the first sub-unit 101, the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the second sub-unit 102, and the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the third sub-pixel unit 103, respectively.

[0070] For two adjacent sub-pixels, if the target vapor deposition areas corresponding to these two sub-pixels are spaced apart, the space at the interval will be wasted, affecting the improvement of the display panel's PPI. If the target vapor deposition areas corresponding to these two sub-pixels overlap, in the presence of process deviations, the light-emitting material corresponding to the sub-pixel may fall into the pixel opening of the adjacent sub-pixel, resulting in display abnormalities.

[0071] In this embodiment of the invention, by making the second target vapor deposition area 22 corresponding to the second sub-pixel SP2 in the third sub-unit 103 tangent to the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the first sub-unit 101, the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the second sub-unit 102, and the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the third sub-pixel unit 103, while ensuring the display effect and improving the PPI of the display panel, the area corresponding to the second sub-pixel SP2 in the third sub-unit 103, the third sub-pixel SP3 in the first sub-unit 101, and the third sub-pixel SP3 in the third sub-pixel unit 103 can be set as large as possible, which is beneficial to improving the aperture ratio of the corresponding sub-pixels.

[0072] Optionally, in embodiments of the present invention, the display panel may include a plurality of the aforementioned first sub-units 101, a plurality of the aforementioned second sub-units 102, and a plurality of the aforementioned third sub-units 103, such that the second target vapor deposition areas 22 corresponding to the plurality of second sub-pixels SP2 are respectively tangent to the third target vapor deposition areas 23 corresponding to the three third sub-pixels SP3 located around the second sub-pixels SP2, thereby increasing the pixel aperture ratio of the plurality of second sub-pixels SP2 and the plurality of third sub-pixels SP3.

[0073] Optionally, as shown in Figure 6, which is a schematic diagram of another target vapor deposition area including multiple sub-pixels provided by an embodiment of the present invention, one of the first unit group 10 and the second unit group 20 includes a fourth sub-unit 104, and the other includes a fifth sub-unit 105 and a sixth sub-unit 106. Figure 6 illustrates that a portion of the first unit U1 in the first unit group 10 includes the fourth sub-unit 104, and a portion of the second unit U2 in the second unit group 20 includes the fifth sub-unit 105 and the sixth sub-unit 106. The fifth sub-unit 105 and the sixth sub-unit 106 are arranged adjacent to each other in the second direction h12, and the sixth sub-unit 106 is located on the side of the first sub-pixel SP1 of the fifth sub-unit 105 away from the second sub-pixel SP2 (taking the orientation shown in Figure 6 as an example, the sixth sub-unit 106 is located below the fifth sub-unit 105). The fourth subunit 104 and the fifth subunit 105 are arranged adjacent to each other in the first direction h11, and the fourth subunit 104 is located on the side of the first sub-pixel SP1 of the fifth subunit 105 away from the second sub-pixel SP2 (taking the orientation shown in Figure 6 as an example, the fourth subunit 104 is located on the left side of the fifth subunit 105); as shown in Figure 6, the display panel includes a second virtual inscribed triangle 32, the first vertex Q21 of the second virtual inscribed triangle 32 coincides with the geometric center O2_105 of the second sub-pixel SP2 in the fifth subunit 105, and the second vertex Q22 of the second virtual inscribed triangle 32 coincides with the geometric center O2_106 of the second sub-pixel SP2 in the sixth subunit 106; the orthographic projection of the third sub-pixel SP3 in the fourth subunit 104 onto the plane where the substrate 1 is located covers the third vertex Q23 of the second virtual inscribed triangle 32.

[0074] As shown in Figure 6, the second virtual inscribed triangle 32 has a second virtual circumscribed circle 42, and the center Q3 of the second virtual circumscribed circle 42 coincides with the geometric center O1_105 of the first sub-pixel SP1 in the fifth sub-unit 105.

[0075] Based on this configuration, the first target vapor deposition area 21 corresponding to the first sub-pixel SP1 in the fifth sub-unit 105 can be made tangent to the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the fourth sub-unit 104, the second target vapor deposition area 22 corresponding to the second sub-pixel SP2 in the fifth sub-unit 105, and the second target vapor deposition area 22 corresponding to the second sub-pixel SP2 in the sixth sub-unit 106, respectively. This avoids the overlap or separation of target vapor deposition areas corresponding to adjacent sub-pixels. While taking into account both increasing the PPI of the display panel and reducing the manufacturing difficulty of the display panel, the area of ​​the first sub-pixel SP1 in the fifth sub-unit 105, the third sub-pixel SP3 in the fourth sub-unit 104, the second sub-pixel SP2 in the fifth sub-unit 105, and the second sub-pixel SP2 in the sixth sub-unit 106 can be increased, which is beneficial to improving the aperture ratio of multiple sub-pixels.

[0076] Optionally, as shown in Figure 7, which is an enlarged schematic diagram of the third sub-pixel SP3 in the fourth sub-unit 104, the first sub-pixel SP1 and the second sub-pixel SP2 in the fifth sub-unit 105, and the second sub-pixel SP2 in the sixth sub-unit 106 of Figure 6, the distance between the third vertex Q23 of the second virtual inscribed triangle 32 and the geometric center O3_4 of the third sub-pixel SP3 in the fourth sub-unit 104 along the first preset direction X1 is L1. The first preset direction X1 is parallel to the third sub-pixel SP3 in the fourth sub-unit 104. The line connecting the geometric center O3_4 of the third sub-pixel SP3 and the geometric center O2_5 of the second sub-pixel SP2 in the fifth sub-unit 105; along the second preset direction X2, the distance between the third vertex Q3 of the second virtual inscribed triangle 32 and the geometric center O3_4 of the third sub-pixel SP3 in the fourth sub-unit is L2, and the second preset direction X2 is parallel to the line connecting the geometric center O3_4 of the third sub-pixel SP3 in the fourth sub-unit 104 and the geometric center O2_6 of the second sub-pixel SP2 in the sixth sub-unit 106. Exemplarily, in this embodiment of the invention, L1 = L2.

[0077] For example, L1 = L2 = r23 - r22, where r23 is the radius of the third target vapor deposition region 23 and r22 is the radius of the second target vapor deposition region 22.

[0078] Based on this configuration, as shown in Figure 7, the third target vapor deposition area 23 corresponding to the third sub-pixel SP3 in the fourth sub-unit 104 and the second target vapor deposition area 22 corresponding to the second sub-pixel SP2 in the fifth sub-unit 105 can be tangent. This is beneficial for increasing the area of ​​the third sub-pixel SP3 in the fourth sub-unit 104 and the second sub-pixel SP2 in the fifth sub-unit 105, improving their aperture ratio, and increasing the space utilization of the display panel.

[0079] For example, embodiments of the present invention may further include at least one first unit U1 and / or at least one second unit U2, as shown in FIG8. FIG8 is a schematic diagram of another display panel provided by an embodiment of the present invention, wherein multiple first units U1 and multiple second units U2 all include a fourth sub-pixel SP4 as an illustration. The fourth sub-pixel SP4 and the second sub-pixel SP2 are arranged along the first direction h11, and the fourth sub-pixel SP4 and the third sub-pixel SP3 are arranged along the second direction h12. The setting of the fourth sub-pixel SP4 can improve the display effect of the display panel. Moreover, by setting the fourth sub-pixel SP4 to be arranged along the first direction h11 with the second sub-pixel SP2 and along the second direction h12 with the third sub-pixel SP3, embodiments of the present invention are beneficial to further improve the space utilization of the display panel.

[0080] Optionally, as shown in Figure 8, the area of ​​the fourth sub-pixel SP4 is less than or equal to the area of ​​at least one of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3.

[0081] Optionally, the aforementioned fourth sub-pixel SP4 includes a white sub-pixel. The white sub-pixel emits white light. The inclusion of a white sub-pixel helps reduce the power consumption of the display panel and increases its brightness.

[0082] For example, as shown in FIG9, which is a schematic diagram of another display panel provided in an embodiment of the present invention, at least one first unit U1 and / or at least one second unit U2 further includes a support portion 4. FIG9 illustrates that multiple first units U1 and multiple second units U2 all include support portions. The support portion 4 can be used to support the mask used in the manufacturing process of the display panel 100. Moreover, by arranging the support portion 4 with the second sub-pixel SP2 along the first direction h11 and with the third sub-pixel SP3 along the second direction h12 in the embodiment of the present invention, it is beneficial to further improve the space utilization of the display panel.

[0083] For example, as shown in FIG10, FIG10 is a schematic diagram of another display panel provided by an embodiment of the present invention. At least one first unit U1 and / or at least one second unit U2 further includes a light-transmitting area 5. FIG10 is illustrated by the fact that multiple first units U1 and multiple second units U2 all include a light-transmitting area 5. The light-transmitting area 5 and the second sub-pixel SP2 are arranged along the first direction h11, and the light-transmitting area 5 and the third sub-pixel SP3 are arranged along the second direction h12.

[0084] Optionally, the light transmittance of the light-transmitting area 5 is greater than or equal to the light transmittance of other areas in the display panel. The setting of the light-transmitting area 5 can improve the light transmittance of the display panel. For example, this display panel can be used in conjunction with a light sensor, allowing ambient light to enter the light sensor through the light-transmitting area 5 when the light sensor is operating. The light sensor can then perform operations such as adjusting the brightness of the display panel in response to the collected ambient light intensity. Furthermore, by arranging the light-transmitting area 5 along the first direction h11 with the second sub-pixel SP2 and along the second direction h12 with the third sub-pixel SP3, this embodiment of the invention further improves the space utilization of the display panel.

[0085] Optionally, the aforementioned light sensors include camera modules, distance sensors, iris recognition sensors, infrared sensors, etc., but are not limited to these.

[0086] For example, as shown in FIG11, FIG11 is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. The display panel further includes a light-shielding layer 40, which is located on the side of the sub-pixel SP away from the substrate 1. The light-shielding layer 40 includes an opening 400, and the orthographic projection of the opening 400 onto the plane of the substrate 1 at least partially overlaps with the light-transmitting area 5. The opening 400 can improve the light transmittance of the light-shielding layer 40 at the location of the light-transmitting area 5.

[0087] Optionally, as shown in Figure 11, the light-emitting layer 02 is disposed away from the light-transmitting area 5 to further increase the light transmittance of the light-transmitting area 5.
