Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the development of technology, the pixel structure in the display panel has gradually developed towards the direction of refined settings, and has begun to pursue the reduction of pixel structure size and the diversification of arrangement methods, focusing on improving display effects.

[0003] When the pixel structure is prepared by the evaporation process, the support structure on the display panel is often used to support the mask. At this time, the support structure needs to be in contact with the mask. During the preparation process, the support structure is easy to scratch the mask, thereby reducing the preparation yield of the pixel structure. Therefore, how to reduce the probability of the mask being scratched by the support structure has become a problem that has attracted much attention. Summary of the invention

[0004] In view of this, the present application provides a display panel and a display device, so as to solve the problem of decreased pixel production yield caused by scratches on the mask.

[0005] In a first aspect, an embodiment of the present application provides a display panel, including a first sub-pixel, a second sub-pixel, a third sub-pixel, and a support portion. The first sub-pixel includes a first A sub-pixel and a first B sub-pixel, the second sub-pixel includes a second A sub-pixel and a second B sub-pixel, and the third sub-pixel includes a third A sub-pixel and a third B sub-pixel.

[0006] The first unit includes a first subunit and a second subunit adjacently arranged along a first direction. The first subunit includes a support portion, a first A subpixel, a second A subpixel, and a second B subpixel arranged along a second direction, the first A subpixel is located between the second A subpixel and the second B subpixel, the second A subpixel is located between the support portion and the first A subpixel, and the first direction and the second direction intersect.

[0007] The second sub-unit includes a first B sub-pixel, a third A sub-pixel and a third B sub-pixel arranged along the second direction, and the third A sub-pixel is located between the first B sub-pixel and the third B sub-pixel.

[0008] In a second aspect, an embodiment of the present application provides a display device, comprising a display panel provided in the first aspect.

[0009] When the second A sub-pixel is prepared using a mask, the arrangement of the embodiment of the present application helps to arrange the support portion farther from the vapor deposition opening corresponding to the second A sub-pixel, so that the risk of the support portion scratching the edge of the vapor deposition opening corresponding to the second A sub-pixel is lower. On the other hand, if the support portion in the first sub-unit is adjacent to the first B sub-pixel in the second sub-unit along the first direction, the spacing between the first sub-unit and the second sub-unit along the first direction can be adjusted to achieve that the support portion is as far away from the first B sub-pixel as possible along the first direction, thereby reducing the risk of the support portion scratching the edge of the vapor deposition opening corresponding to the first B sub-pixel.

[0033] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0034] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0035] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0036] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0037] Figure 1 is a schematic diagram of a preparation process of a partial structure of a display panel related to the present application, Figure 2 for Figure 1 The projection diagram of the partial structure shown; it should be noted that Figure 1 Only a portion of the structure of the display panel during the preparation process is shown in FIG. Figure 1 Some of the structures shown in the figure are not in the finished state. For ease of understanding, Figure 2 Only the projection of the support structure and the projection of the evaporation opening are shown.

[0038] In the prior art, Figure 1 As shown, in the process of preparing the pixel structure on the display panel, it is usually necessary to fill the material constituting the pixel structure into the pixel opening 01a pre-set on the pixel definition layer 001, wherein the common method of filling the material constituting the pixel structure into the pixel opening 01a may include evaporation. For example, when preparing a pixel structure of a certain color, the material constituting the pixel structure of the color can be processed into a gaseous material that can be used for the evaporation process, and then the gaseous material can be filled into the pixel opening 01a through the evaporation opening 02a on the mask 002. It should be noted that the mask 002 usually needs to contact with the support structure 003 on the display panel, so that the support structure 003 can play the role of supporting the mask 002 to ensure that the evaporation process proceeds smoothly. However, in the process of the support structure 003 and the mask 002 being aligned and contacted or in the process of evaporation, it is easy to cause the support structure 003 to scratch the mask 002 due to the relative position offset between the support structure 003 and the mask 002.

[0039] like Figure 2 As shown, the projection 031 of the support structure 003 and the projection 021 of the evaporation opening 02a may be adjacent. Figure 1 and Figure 2The distance between the portion of the support structure 003 that contacts the mask 002 and the evaporation opening 02a is small. If the relative position between the support structure 003 and the mask 002 is offset, the support structure 003 is likely to scratch the edge of the evaporation opening 02a, affecting the evaporation process and thereby reducing the preparation yield of the pixel structure.

[0040] Figure 3 A schematic top view of a partial structure of a display panel provided in the present application.

[0041] In view of the above problems, the present application provides a display panel 20, such as Figure 3 As shown, the display panel 20 at least includes a first sub-pixel 01, a second sub-pixel 02, a third sub-pixel 03 and a support portion 10. The luminous colors of the first sub-pixel 01, the luminous colors of the second sub-pixel 02 and the luminous colors of the third sub-pixel 03 can be different. For example, the first sub-pixel 01 can be a red pixel, the second sub-pixel 02 can be a green pixel, and the third sub-pixel 03 can be a blue pixel.

[0042] The first sub-pixel 01 includes a first A sub-pixel 11 and a first B sub-pixel 12, the second sub-pixel 02 includes a second A sub-pixel 21 and a second B sub-pixel 22, and the third sub-pixel 03 includes a third A sub-pixel 31 and a third B sub-pixel 32. The luminous color of the first A sub-pixel 11 and the luminous color of the first B sub-pixel 12 may be the same, the luminous color of the second A sub-pixel 21 and the luminous color of the second B sub-pixel 22 may be the same, and the luminous color of the third A sub-pixel 31 and the luminous color of the third B sub-pixel 32 may be the same.

[0043] The display panel 20 further includes a first unit U1 , and the first unit U1 includes a first sub-unit U11 and a second sub-unit U12 that are adjacently disposed along the first direction X.

[0044] The first sub-unit U11 includes a support portion 10, a first A sub-pixel 11, a second A sub-pixel 21, and a second B sub-pixel 22 arranged along a second direction Y. The first A sub-pixel 11 is located between the second A sub-pixel 21 and the second B sub-pixel 22, and the second A sub-pixel 21 is located between the support portion 10 and the first A sub-pixel 11. The first direction X and the second direction Y intersect.

[0045] The second sub-unit U12 includes a first B sub-pixel 12 , a third A sub-pixel 31 and a third B sub-pixel 32 arranged along the second direction Y, and the third A sub-pixel 31 is located between the first B sub-pixel 12 and the third B sub-pixel 32 .

[0046] In the embodiment of the present application, in the first sub-unit U11, since the support portion 10 can be located on the side of the second A sub-pixel 21 away from the first A sub-pixel 11, the support portion 10 can be set in the edge area of ​​the first sub-unit U11 along the second direction Y, and the edge area can be as far away from the sub-pixel in the first sub-unit U11 as possible. At this time, when the second A sub-pixel 21 is prepared using a mask, the support portion 10 can be far away from the evaporation opening corresponding to the second A sub-pixel 21, and the risk of the support portion 10 scratching the edge of the evaporation opening corresponding to the second A sub-pixel 21 is small. On the other hand, if the support portion 10 in the first sub-unit U11 is adjacent to the first B sub-pixel 12 in the second sub-unit U12 along the first direction X, the spacing between the first sub-unit U11 and the second sub-unit U12 along the first direction X can be adjusted to achieve the support portion 10 as far away from the first B sub-pixel 12 as possible along the first direction X, thereby reducing the risk of the support portion 10 scratching the edge of the evaporation opening corresponding to the first B sub-pixel 12.

[0047] In one embodiment of the present application, Figure 3 As shown, in the same first unit U1, the support portion 10 and the first B sub-pixel 12 are adjacent in the first direction X and the minimum distance between them is D1, and the minimum distance between the second A sub-pixel 21 and the third A sub-pixel 31 in the first direction X is D2. 2*D1≥D2.

[0048] Figure 4 This is a schematic top view of a partial structure of a display panel provided in the present application. For ease of understanding, Figure 4 The figure illustrates a partial structure when a partial pixel on a display panel is prepared using a mask. The pixel structure shown in the figure is the first sub-pixel when evaporation is completed using an evaporation opening. The mask shown in the figure does not belong to the structure included in the finished display panel.

[0049] Combination Figure 3 and Figure 4 , the evaporation opening 02a on the mask 002 can be used to prepare the first B sub-pixel 12. Considering factors such as process errors, the evaporation opening 02a can cover the first B sub-pixel 12 in a direction perpendicular to the plane where the display panel 20 is located. The distance between the projection of the edge of the evaporation opening 02a on the plane where the pixel is located and the projection of the edge of the first B sub-pixel 12 on the plane where the pixel is located (the edge distance corresponding to the first B sub-pixel 12) can be D1. At this time, if the possibility of the support part 10 scratching the edge of the evaporation opening 02a is to be reduced, the support part 10 can be prevented from contacting the edge of the evaporation opening 02a during the evaporation process, and D1 can be regarded as the minimum distance between the support part 10 and the first B sub-pixel 12 in the first direction X.

[0050] like Figure 3As shown, since the second A sub-pixel 21 and the third A sub-pixel 31 may be adjacent to each other in the first direction X, in order to avoid the mixing of the evaporated material of the second A sub-pixel 21 and the evaporated material of the third A sub-pixel 31 during the evaporation process, it is usually necessary to set the minimum spacing between the second A sub-pixel 21 and the third A sub-pixel 31 along the first direction X to be D2. Among them, D2 may be equal to the sum of the edge spacing corresponding to the second A sub-pixel 21 and the edge spacing corresponding to the third A sub-pixel 31, and the edge spacing corresponding to the second A sub-pixel 21 may be equal to the edge spacing corresponding to the third A sub-pixel 31.

[0051] In the embodiment of the present application, in order to prevent the support portion 10 from contacting the edge of the evaporation opening corresponding to the first B sub-pixel 12 during the evaporation process, the minimum spacing D1 between the support portion 10 and the first B sub-pixel 12 along the first direction X can be set to be ≥ 0.5*D2. Among them, since the edge spacing corresponding to the second A sub-pixel 21 can be equal to the edge spacing corresponding to the third A sub-pixel 31, 0.5*D2 can be regarded as the edge spacing corresponding to the second A sub-pixel 21 (or the third A sub-pixel 31).

[0052] In one embodiment of the present application, Figure 3 As shown, along the first direction X, the first A sub-pixel 11 partially overlaps with the third A sub-pixel 31 and the third B sub-pixel 32 .

[0053] In the embodiment of the present application, since the first A sub-pixel 11 overlaps with the third A sub-pixel 31 and the third B sub-pixel 32, the spacing between the third A sub-pixel 31 and the third B sub-pixel 32 in the second direction Y can be less than the length of the first A sub-pixel 11 along the second direction Y. At this time, the spacing between the third A sub-pixel 31 and the third B sub-pixel 32 in the second direction Y can be smaller. This arrangement helps to achieve the relatively concentrated arrangement of the third A sub-pixel 31 and the third B sub-pixel 32 along the second direction Y, which is conducive to reducing the area of ​​the adjacent region between the third A sub-pixel 31 and the third B sub-pixel 32 without reducing their respective areas, thereby increasing the pixel light-emitting area and improving the aperture ratio of the display panel.

[0054] In one embodiment of the present application, Figure 3 As shown, in the same first unit U1, along the second direction Y, the minimum distance between the support portion 10 and the second A sub-pixel 21 is H1, and the minimum distance between the first B sub-pixel 12 and the third A sub-pixel 31 is H2. 2*H1≥H2.

[0055] Considering factors such as process errors, the evaporation opening corresponding to the second A sub-pixel 21 may cover the second A sub-pixel 21 in a direction perpendicular to the plane where the display panel 20 is located, and the edge spacing corresponding to the second A sub-pixel 21 may be H1. At this time, if the possibility of the support portion 10 scratching the edge of the evaporation opening corresponding to the second A sub-pixel 21 is to be reduced, the support portion 10 may be prevented from contacting the edge of the evaporation opening during the evaporation process, and H1 may be regarded as the minimum distance between the support portion 10 and the second A sub-pixel 21 in the second direction Y.

[0056] like Figure 3 As shown, since the first B sub-pixel 12 and the third A sub-pixel 31 may be adjacent to each other in the second direction Y, in order to avoid the mixing of the evaporated material of the first B sub-pixel 12 and the evaporated material of the third A sub-pixel 31 during the evaporation process, it is usually necessary to set the minimum spacing between the first B sub-pixel 12 and the third A sub-pixel 31 along the first direction X to be D2. Wherein, D2 may be equal to the sum of the edge spacing corresponding to the first B sub-pixel 12 and the edge spacing corresponding to the third A sub-pixel 31, and the edge spacing corresponding to the first B sub-pixel 12 may be equal to the edge spacing corresponding to the third A sub-pixel 31.

[0057] In the embodiment of the present application, in order to prevent the support portion 10 from contacting the edge of the evaporation opening corresponding to the second A sub-pixel 21 during the evaporation process, the minimum spacing H1 ≥ 0.5*H2 between the support portion 10 and the second A sub-pixel 21 along the second direction Y can be set. Among them, since the edge spacing corresponding to the first B sub-pixel 12 can be equal to the edge spacing corresponding to the third A sub-pixel 31, 0.5*D2 can be regarded as the edge spacing corresponding to the first B sub-pixel 12 (or the third A sub-pixel 31).

[0058] Figure 5 A schematic top view of a partial structure of a display panel provided in the present application.

[0059] In one embodiment of the present application, Figure 5 As shown, in the same first unit U1, along the first direction X, the minimum distance between the first A sub-pixel 11 and the third B sub-pixel 32 is D3, D3 = D1. Wherein, along the second direction Y, the minimum distance between the first A sub-pixel 11 and the second B sub-pixel 22 is H3, H3 < H1.

[0060] In the embodiment of the present application, since D3=D1 and D1 can be the minimum distance between the support portion 10 and the first B sub-pixel 12 in the first direction X, the spacing between the first A sub-pixel 11 and the third B sub-pixel 32 can be smaller. Considering that H3

[0061] Figure 6 A schematic top view of a partial structure of a display panel provided in the present application.

[0062] In one embodiment of the present application, Figure 6 As shown, in the same first unit U1, along the second direction Y, the minimum distance between the first A sub-pixel 11 and the second B sub-pixel 22 is H3, H3 = H1. Wherein, along the first direction X, the minimum distance between the first A sub-pixel 11 and the third B sub-pixel 32 is D3, D3 < D1.

[0063] The arrangement of the present application helps to realize the centralized arrangement of the first A sub-pixel 11, the second B sub-pixel 22 and the third B sub-pixel 32, which is beneficial to increase the arrangement density of pixels of different luminous colors and improve the resolution of the display screen.

[0064] In one possible implementation, Figure 6 As shown, along the first direction X, the distance between the second A sub-pixel 21 and the third A sub-pixel 31 may be D4, where D4>D3.

[0065] In one possible implementation, Figure 6 As shown, along the first direction X, the distance between the second B sub-pixel 22 and the third B sub-pixel 32 may be D5, where D5=D4>D3.

[0066] In a possible implementation, along the first direction X, the distance between the second A sub-pixel 21 and the third A sub-pixel 31 may be D4, where D4=D3.

[0067] In a possible implementation, along the first direction X, the distance between the second B sub-pixel 22 and the third B sub-pixel 32 may be D5, where D5=D4=D3.

[0069] In one embodiment of the present application, Figure 7 ​As shown, in the same first unit U1, along the first direction X, the minimum distance between the first A sub-pixel 11 and the third B sub-pixel 32 is D3, D3 = D1; and along the second direction Y, the minimum distance between the first A sub-pixel 11 and the second B sub-pixel 22 is H3, H3 = H1.

[0070] In the embodiment of the present application, the configuration of D3=D1 and H3=H1 is relatively simple, which helps to reduce the difficulty of manufacturing the display panel 20, and in particular, can simplify the preparation of pixel openings for setting pixels.

[0071] Figure 8 A schematic top view of a partial structure of a display panel provided in the present application.

[0072] In one embodiment of the present application, Figure 8 As shown, in the same first unit U1, along the first direction X, the minimum distance between the first A sub-pixel 11 and the third B sub-pixel 32 is D3, D3>D1. Wherein, along the second direction Y, the minimum distance between the first A sub-pixel 11 and the second B sub-pixel 22 is H3, H3=H1.

[0073] In the embodiment of the present application, since the first A sub-pixel 11 and the third B sub-pixel 32 can be adjacent to each other along the first direction X and the luminous colors of the two can be different, the arrangement of D3>D1 helps to achieve a larger spacing between the first A sub-pixel 11 and the third B sub-pixel 32 in the first direction X, thereby reducing the probability of pixel material mixing during the preparation process. In addition, the arrangement of H3=H1 can simplify the preparation of the pixel opening used to set the pixel.

[0074] Fig. 9 A schematic top view of a partial structure of a display panel provided in the present application.

[0075] In one embodiment of the present application, Fig. 9 As shown, in the same first unit U1, along the second direction Y, the minimum distance between the first A sub-pixel 11 and the second B sub-pixel 22 is H3, H3>H1. Wherein, along the first direction X, the minimum distance between the first A sub-pixel 11 and the third B sub-pixel 32 is D3, D3=D1.

[0076] In the embodiment of the present application, since the first A sub-pixel 11 and the second B sub-pixel 22 can be adjacent to each other along the second direction Y and the luminous colors of the two can be different, the arrangement of H3>H1 helps to achieve a larger spacing between the first A sub-pixel 11 and the second B sub-pixel 22 in the second direction Y, thereby reducing the probability of pixel material mixing during the preparation process. In addition, the arrangement of D3=D1 can simplify the preparation of the pixel opening used to set the pixel.

[0077] Fig.10 A schematic top view of a partial structure of a display panel provided in the present application.

[0078] In one embodiment of the present application, Fig.10 As shown, in the same first unit U1, along the first direction X, the minimum distance between the first A sub-pixel 11 and the third B sub-pixel 32 is D3, D3>D1. Also, along the second direction Y, the minimum distance between the first A sub-pixel 11 and the second B sub-pixel 22 is H3, H3>H1.

[0079] In the embodiment of the present application, the preparation method of D3>D1 and H3>H1 helps to achieve a larger spacing between some pixels in the same first unit U1, reduce the probability of pixel material mixing during the preparation process, and improve the yield of the finished product.

[0080] Fig.11 A schematic top view of a partial structure of a display panel provided in the present application.

[0081] In one embodiment of the present application, Fig.11 As shown, a plurality of first units U1 are arranged in a matrix along a first direction X and a second direction Y.

[0082] In the embodiment of the present application, the matrix arrangement of the first unit U1 is conducive to achieving the regularity of the arrangement of pixels on the display panel 20, and the matrix arrangement of multiple first units U1 helps to use the first unit U1 as the basic unit during the preparation process, and to batch-arrange the pixels and support parts 10 in the first unit U1 on the display panel 20, thereby reducing the difficulty of preparation.

[0083] In one embodiment of the present application, Fig.11 As shown, in the four first units U1 arranged in a 2×2 matrix along the first direction X and the second direction Y, the center connecting line of the four support parts 10 is a rectangle, as shown by the rectangular wireframe A1 in the figure.

[0084] In one possible implementation, Fig.11 As shown, along the second direction Y, the spacing between the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 can be D6; the minimum distance between the third B sub-pixel 32 and the third A sub-pixel 31 in another first unit U1 adjacent to the third B sub-pixel 32 along the second direction Y can be D7, and D7>D6.

[0085] In this implementation, since D7>D6, it can be considered that the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 are centrally arranged, and the distance between the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 is small in the second direction Y. Therefore, when the third sub-pixel 03 is prepared using a mask, the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 can be evaporated using the same evaporation opening, thereby reducing the number of evaporation openings on the mask and reducing the preparation cost.

[0087] It should be noted that Fig.12 Indicated in Fig.11 The distribution of the evaporation openings S1a on the first mask S1 used in preparing the first A sub-pixel 11 and the first B sub-pixel 12 on the display panel 20 shown; Fig.13 Indicated in Fig.11 The distribution of the evaporation openings S2a on the second mask S2 used in preparing the second A sub-pixel 21 and the second B sub-pixel 22 on the display panel 20 shown; Fig.14 Indicated in Fig.11 The distribution of the evaporation openings S3a on the third mask S3 used in the preparation of the third A sub-pixel 31 and the third B sub-pixel 32 on the display panel 20 is shown. The mask does not belong to the structure included in the finished display panel.

[0088] In one embodiment of the present application, Fig.11 As shown, along the second direction Y, the distance between the third A sub-pixel 31 and the third B sub-pixel 32 is smaller than the distance between the first B sub-pixel 12 and the third A sub-pixel 31 .

[0089] The arrangement of this embodiment can realize the centralized arrangement of the third A sub-pixel 31 and the third B sub-pixel 32. Since the luminous color of the third A sub-pixel 31 and the luminous color of the third B sub-pixel 32 can be the same, in the preparation process of the third sub-pixel 03, the third sub-pixel 03 can be arranged in a centralized manner. Fig.11 and Fig.14 The third A sub-pixel 31 and the third B sub-pixel 32 can be evaporated using the same evaporation opening, which helps to reduce the number of evaporation openings S3a on the third mask S3, reduce the difficulty of preparing the third mask S3, and reduce costs.

[0091] In one possible implementation, Fig.15 As shown, the multiple first units U1 arranged along the first direction X may include two adjacent first units U1, and the third A sub-pixels 31 respectively included in the two adjacent first units U1 may be adjacent along the first direction X, and the third B sub-pixels 32 respectively included in the two adjacent first units U1 may be adjacent along the first direction X.

[0092] Since the luminous color of the third A sub-pixel 31 and the luminous color of the third B sub-pixel 32 can be the same, the constituent material of the third A sub-pixel 31 and the constituent material of the third B sub-pixel 32 can be the same. The setting method of this implementation can centrally set the third A sub-pixel 31 and the third B sub-pixel 32 in two adjacent first units U1. Considering that the constituent material of the third A sub-pixel 31 and the constituent material of the third B sub-pixel 32 can be the same, even if the constituent materials of different pixels are mixed with each other during the preparation process, this situation has little impact on the third sub-pixel 03, which is conducive to improving the preparation yield.

[0093] In addition, if Fig.15 As shown, there are two first units U1 adjacent to each other along the first direction X, the first A sub-pixels 11 respectively included in the two first units U1 may be adjacent to each other, and the second A sub-pixels 21 respectively included in the two first units U1 may be adjacent to each other, and the second B sub-pixels 22 respectively included in the two first units U1 may be adjacent to each other.

[0094] In one embodiment of the present application, Fig.11 As shown, in two first units U1 adjacently arranged along the first direction X, the center connecting line of the two first A sub-pixels 11 and the two first B sub-pixels 12 forms a parallelogram, as shown by the parallelogram wireframe A2 in the figure.

[0095] In one embodiment of the present application, Fig.11 As shown, in two first units U1 adjacently arranged along the first direction X, the center line connecting the two second A sub-pixels 21 and the two second B sub-pixels 22 forms a square, as shown by the square wireframe A3 in the figure.

[0096] Fig.16 A schematic top view of a partial structure of a display panel provided in the present application.

[0097] In one embodiment of the present application, Fig.16 As shown, along the second direction Y, in the same first unit U1, the minimum distance between the third A sub-pixel 31 and the third B sub-pixel 32 is D11.

[0098] Along the second direction Y, the minimum distance between the third A sub-pixel 31 and the third B sub-pixel 32 respectively located in two adjacent first units U1 is D12, and D12>D11.

[0099] In this embodiment, since D12>D11, it can be considered that the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 are centrally arranged, and the distance between the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 is small in the second direction Y. Therefore, when the third sub-pixel 03 is prepared by using a mask, the third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 can be evaporated using the same evaporation opening, thereby reducing the number of evaporation openings on the mask.

[0100] Fig.17 A schematic top view of a partial structure of a display panel provided in the present application.

[0101] In one embodiment of the present application, Fig.17 As shown, a plurality of first units U1 are arranged in sequence along the second direction Y. Along the first direction X, a first unit U1 partially overlaps with two first units U1 in an adjacent column.

[0102] Fig.18 Schematic diagram of a top view of a mask. Fig.19 Schematic diagram of a top view of a mask. Fig. 20 A schematic top view of a mask.

[0103] It should be noted that Fig.18 Indicated in Fig.17 The distribution of the evaporation openings S1a on the first mask S1 used in preparing the first A sub-pixel 11 and the first B sub-pixel 12 on the display panel 20 shown; Fig.19 Indicated in Fig.17 The distribution of the evaporation openings S2a on the second mask S2 used in preparing the second A sub-pixel 21 and the second B sub-pixel 22 on the display panel 20 shown; Fig. 20 Indicated in Fig.17 The distribution of the evaporation openings S3a on the third mask S3 used in the preparation of the third A sub-pixel 31 and the third B sub-pixel 32 on the display panel 20 is shown. The mask does not belong to the structure included in the finished display panel.

[0104] In one possible implementation, Fig.17 As shown, for two first units U1 adjacent along the first direction X, the first A sub-pixels 11 respectively included in the two first units U1 are adjacent along the first direction X, or the first B sub-pixels 12 respectively included in the two first units U1 are adjacent along the first direction X.

[0105] In this implementation, combined with Fig.17 and Fig.18 , two first A sub-pixels 11 adjacent along the first direction X may correspond to the same evaporation opening S1a on the first mask S1, and two first B sub-pixels 12 adjacent along the first direction X may correspond to the same evaporation opening S1a on the first mask S1. This arrangement helps to reduce the number of evaporation openings S1a on the first mask S1 and reduce the manufacturing cost of the first mask S1.

[0106] In addition, combined Fig.17 and Fig. 20 The third A sub-pixel 31 and the third B sub-pixel 32 in the same first unit U1 may correspond to the same evaporation opening S3a on the third mask S3.

[0107] In one embodiment of the present application, Fig.17 As shown, the center lines of the four second sub-pixels 02 arranged in a 2×2 matrix along the first direction X and the second direction Y are in a square shape. The multiple first units U1 overlapping along the first direction X include a main first unit U1a, a secondary first unit U1b, and a secondary secondary first unit U1c. The center lines of the second A sub-pixel 21 and the second B sub-pixel 22 in the main first unit U1a, the second B sub-pixel 22 in the secondary first unit U1b, and the second A sub-pixel 21 in the secondary secondary first unit U1c are in a square shape, as shown by the square wireframe A4 in the figure.

[0108] Fig.21 A schematic top view of a partial structure of a display panel provided in the present application.

[0109] In one embodiment of the present application, Fig.21 As shown, the center line connecting four adjacent support portions 10 is a rhombus.

[0110] The display panel 20 may include a first pixel row L1 and a second pixel row L2 alternately arranged along the second direction Y. The first pixel row L1 includes a support portion 10 and a first A pixel group 41 alternately arranged along the first direction X, and the first A pixel group 41 includes two first A sub-pixels 11 adjacent to each other along the first direction X; the second pixel row L2 includes a support portion 10 and a first B pixel group 42 alternately arranged along the first direction X, and the first B pixel group 42 includes two first B sub-pixels 12 adjacent to each other along the first direction X. In the second direction Y, the support portion 10 in the first pixel row L1 may overlap with the first B pixel group 42 in the second pixel row L2, and the support portion 10 in the second pixel row L2 may overlap with the first A pixel group 41 in the first pixel row L1. For a first B pixel group 42 in the second pixel row L2, the center line connecting two support portions 10 adjacent to the first B pixel group 42 along the second direction Y and located in the first pixel row L1 and two support portions 10 adjacent to the first B pixel group 42 along the first direction X and located in the same second pixel row L2 can be a rhombus, as shown in the diamond solid line frame A5 in the figure.

[0111] In a possible implementation, along the second direction Y, the support portions 10 in the first pixel row L1 may not overlap with the support portions 10 in the second pixel row L2.

[0112] In one possible implementation, Fig.21 As shown, in the same first pixel row L1, along the first direction X, the spacing between the first A pixel group 41 and the supporting portion 10 is greater than the spacing between the two first A sub-pixels 11 included in the first A pixel group 41; in the same second pixel row L2, along the first direction X, the spacing between the first B pixel group 42 and the supporting portion 10 is greater than the spacing between the two first B sub-pixels 12 included in the first B pixel group 42.

The display device 30 may be a vehicle-mounted display device. In addition, the display device 30 may also be an electronic device such as a computer or a television.

[0115] The display device 30 provided in the present application has a high pixel production yield in the display panel 20 , and there is no phenomenon of a decrease in pixel production yield due to scratches on the edges of the mask evaporation openings.
