[0064] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0065] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “upper,” “lower,” “left,” and “right,” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0066] In this disclosure, "multiple or several" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0067] It should be noted that the row direction and column direction involved in the embodiments of this disclosure represent only two different directions, and they are not limited to being perpendicular to each other. The accompanying drawings of the embodiments of this disclosure are only used as an example of the row direction and column direction being perpendicular, but this does not constitute a limitation on the embodiments of this disclosure.

[0068] Furthermore, the descriptions of "same" and "equal" used in the embodiments of this disclosure do not mean that two objects are completely equal in size or have the same shape. They are allowed to be approximately the same or approximately equal within a certain error range.

[0069] Before describing the display panel, display device, and high-precision photomask according to embodiments of this disclosure, the specific structure of the display panel will first be explained. As shown in Figures 1 and 2, the display panel mainly includes a substrate 1 and a pixel definition layer (PDL) disposed on the substrate 1. The PDL has pixel openings corresponding one-to-one with sub-pixels. The shape of each sub-pixel is typically determined by the pixel opening in the PDL. Since the light-emitting layer is at least partially formed in the pixel opening, it defines the shape of the light-emitting area of ​​the sub-pixel, which is the outline shape of the sub-pixel's orthographic projection on the substrate 1 as referred to in this disclosure embodiment. When the pixel opening is polygonal, the sub-pixel is polygonal. The pixel opening corresponding to the sub-pixel is also the light-emitting area corresponding to that sub-pixel. The deposition of the light-emitting layer material requires the aid of a high-precision photomask. The deposition opening of the high-precision photomask determines the light-emitting layer pattern corresponding to a single sub-pixel or the light-emitting layer pattern corresponding to multiple sub-pixels, which is the material deposition area where the sub-pixel is located as referred to in this disclosure embodiment. The pixel opening falls into the material deposition area, which is slightly larger than the light-emitting area of ​​the sub-pixel within its range.

[0070] In this embodiment, the display panel refers to the arrangement of light-emitting devices of different colors in the display substrate, and is not limited to the arrangement of pixel circuits used to drive each light-emitting device. Accordingly, it should be understood that in this embodiment, sub-pixels refer to the structure of the light-emitting devices, and the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03 represent three different colored sub-pixels. In this embodiment, the first sub-pixel 01 is described as a red sub-pixel, the second sub-pixel 02 as a green sub-pixel, and the third sub-pixel 03 as a blue sub-pixel. However, the fact that the first sub-pixel 01 is a red sub-pixel, the second sub-pixel 02 is a green sub-pixel, and the third sub-pixel 03 is a blue sub-pixel does not constitute a limitation on the scope of protection of this embodiment.

[0071] In a first aspect, the present disclosure provides a display panel. FIG1 is a schematic diagram of the display panel of the present disclosure embodiment 1, FIG2 is a cross-sectional view of the structure shown in FIG1 along the A-A' direction, and FIG3 is a schematic diagram of the sub-pixel arrangement corresponding to a virtual frame in FIG1.

[0072] As shown in Figures 1 and 2, the display panel includes a substrate 1 and a plurality of sub-pixels located on the substrate 1. The plurality of sub-pixels include a first sub-pixel 01, a second sub-pixel 02 and a third sub-pixel 03; wherein at least two third sub-pixels 03 are arranged adjacently and form a third sub-pixel group 04.

[0073] As shown in Figure 1, multiple third sub-pixel groups 04 are arranged in an array, including multiple columns of third sub-pixel columns 10 arranged side by side along the row direction X. Each column of third sub-pixel columns 10 includes multiple third sub-pixel groups 04 arranged side by side along the column direction Y, and the third sub-pixel groups 04 in adjacent columns of third sub-pixel columns 10 are staggered.

[0074] As shown in Figure 3, for any third sub-pixel group 04, it is surrounded by first sub-pixels 01 and second sub-pixels 02, and the first sub-pixels 01 and second sub-pixels 02 are alternately arranged along the direction surrounding the third sub-pixel group 04. For the plurality of first sub-pixels 01 and the plurality of second sub-pixels 02 surrounding the third sub-pixel group 04, their orthogonal projections on the substrate 1 are circumscribed by a virtual frame 2; the center of the virtual frame 2 is the first center O of the orthogonal projection of the third sub-pixel group 04 on the substrate 1. For any virtual frame 2, the orthogonal projections of the first light-emitting center P1 of any first sub-pixel 01 and the second light-emitting center P2 of any second sub-pixel 02 contained therein on the substrate 1 are all located on the line connecting the midpoints of the two adjacent sides of the virtual frame 2, that is, on the line connecting the first centers described below.

[0075] Figure 4 is a schematic diagram of the relevant pixel arrangement, showing 3×3 pixel units. Compared with the pixel arrangement shown in Figure 4, the pixel arrangement structure provided in this embodiment makes full use of the layout space between sub-pixels. By adjusting the arrangement of sub-pixels, the proportion of light-emitting display area is effectively increased without reducing pixel density, and the aperture ratio is increased, thereby effectively improving the display brightness and lifespan of the display panel.

[0076] Optionally, the virtual frame 2 is a rectangle. For a pair of adjacent sides of the virtual frame 2, one side extends in the row direction (X) and the other side extends in the column direction (Y). For example, the virtual frame 2 is a square. The following description uses a square virtual frame 2 as an example.

[0077] Optionally, a virtual frame 2 may include a third sub-pixel group 04, four first sub-pixels 01 and four second sub-pixels 02, and the four first sub-pixels 01 and four second sub-pixels 02 may be alternately arranged along the direction surrounding the third sub-pixel group 04.

[0078] Optionally, as shown in Figure 1, the virtual boxes 2 corresponding to different third sub-pixel groups 04 overlap. Taking the virtual box 2 as a square as an example, any two adjacent virtual boxes 2 corresponding to the third sub-pixel groups 04 overlap by one-quarter of their area, and the overlapping area includes a first sub-pixel 01 and a second sub-pixel 02.

[0079] Optionally, for any two adjacent first sub-pixels 01 and 02, the angle formed by the line connecting the first light-emitting center P1 and the first center O and the line connecting the second light-emitting center P2 and the first center O is 45°.

[0080] In some embodiments, as shown in FIG1, the display panel further includes a first material vapor deposition area 31, a second material vapor deposition area 32, and a third material vapor deposition area 33; a first sub-pixel 01 is located in the first material vapor deposition area 31, a second sub-pixel 02 is located in the second material vapor deposition area 32, and a plurality of third sub-pixels 03 in the third sub-pixel group 04 are all located in the third material vapor deposition area 33; the center of the first material vapor deposition area 31 is the first light-emitting center P1 of the first sub-pixel 01; the center of the second material vapor deposition area 32 is the second light-emitting center P2 of the second sub-pixel 02; the center of the third material vapor deposition area 33 is the midpoint of the pattern formed by the lines connecting the plurality of third light-emitting centers P3 in the third sub-pixel group 04, which is also the first center O.

[0081] The first material evaporation area 31 corresponds to the first evaporation opening on the high-precision mask for evaporating the light-emitting material of the first sub-pixel 01. The second material evaporation area 32 corresponds to the second evaporation opening on the high-precision mask for evaporating the light-emitting material of the second sub-pixel 02. The third material evaporation area 33 corresponds to the third evaporation opening on the high-precision mask for evaporating the light-emitting material of the third sub-pixel 03. The size of the first evaporation opening is slightly larger than the size of the first pixel opening 011 of the first sub-pixel 01; the size of the second evaporation opening is slightly larger than the size of the second pixel opening 021 of the second sub-pixel 02; and the size of the third evaporation opening is slightly larger than the size of the third pixel opening 031 of the third sub-pixel 03. Therefore, the size of the first material evaporation area 31 is slightly larger than the size of the first pixel opening 011 of the first sub-pixel 01; the size of the second material evaporation area 32 is slightly larger than the size of the second pixel opening 021 of the second sub-pixel 02; and the size of the third material evaporation area 33 is larger than the size of the third pixel opening 031 of the third sub-pixel 03.

[0082] It should be noted that the sub-pixels involved in the embodiments of this disclosure are only the sub-pixels corresponding to the actual light-emitting areas, and do not include the light-emitting materials of the sub-pixels corresponding to the non-light-emitting positions.

[0083] In this embodiment, the third sub-pixel 03 in the same group of third sub-pixel groups 04 is located in the same third material evaporation area 33. This means that when multiple third sub-pixels 03 in the same group of third sub-pixel groups 04 are deposited with light-emitting materials, they share the same third evaporation opening of the high-precision mask, thereby increasing the area ratio of the light-emitting region of the third sub-pixel 03 (that is, the ratio of the light-emitting region of the third sub-pixel 03 to the fixed area occupied by the pixel unit), making full use of the layout space and reducing space waste.

[0084] Figure 5 is a schematic diagram of the display panel of Embodiment 2 of this disclosure, and Figure 6 is a schematic diagram of the display panel of Embodiment 3 of this disclosure.

[0085] In some embodiments, as shown in Figures 3, 5 and 6, the third sub-pixel group 04 includes two third sub-pixels 03; for a third sub-pixel group 04, the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically arranged with reference lines in any direction of the plane where the virtual frame 2 is located as the axis of symmetry.

[0086] In the pixel arrangement structure provided in this embodiment, for one of the multiple third sub-pixel groups 04, the third sub-pixel group 04 specifically includes two third sub-pixels 03, which are symmetrically arranged, and the extension direction of their axis of symmetry can be any direction of the plane where the virtual frame 2 is located. The arrangement of the third sub-pixels 03 in the remaining third sub-pixel groups 04 can be set sequentially according to a predefined arrangement of a set of third sub-pixels 03.

[0087] However, depending on the direction of the extension of the axis of symmetry, the position of the third light-emitting center P3 of the third sub-pixel 03 is different, and the first sub-pixel 01 and the second sub-pixel 02 that together with the third sub-pixel 03 constitute the pixel unit may be different. See the detailed description of different embodiments 1 to 3 below.

[0088] In some embodiments, for a set of adjacent sides in the virtual frame 2, one side extends in the row direction X, and the other side extends in the column direction Y. Figure 7 is a schematic diagram of the virtual frame provided in an embodiment of the present disclosure. As shown in Figure 7, the virtual frame 2 includes a first side 21, a second side 22, a third side 23, and a fourth side 24. The first side 21 and the third side 23 are two sides arranged opposite each other along the row direction X, with the first side 21 on the left and the second side 22 on the right. The second side 22 and the fourth side 24 are two sides arranged opposite each other along the column direction Y, with the second side 22 on top and the fourth side 24 on the bottom. The virtual frame 2 includes a first intersection point A where the first side 21 and the second side 22 meet, a second intersection point B where the second side 22 and the third side 23 meet, a third intersection point C where the third side 23 and the fourth side 24 meet, and a fourth intersection point D where the fourth side 24 and the first side 21 meet. In addition, the virtual frame 2 includes two diagonals, denoted as the first diagonal T1 and the second diagonal T2, which are perpendicular to each other. Optionally, the first diagonal T1 is the straight line connecting the second intersection point B and the fourth intersection point D in the virtual frame 2; the second diagonal T2 is the straight line connecting the first intersection point A and the third intersection point C in the virtual frame 2.

[0089] As shown in Figure 3, for the even-numbered column third sub-pixel group 04, the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically set with the first diagonal T1 in the virtual frame 2 as the axis of symmetry; for the odd-numbered column third sub-pixel group 04, the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically set with the second diagonal T2 in the virtual frame 2 as the axis of symmetry.

[0090] As shown in Figure 3, for any two adjacent third sub-pixel groups 04 along the extension direction of the first diagonal T1, the line connecting the third luminous centers P3 of the two third sub-pixels 03 in one group is perpendicular to the line connecting the third luminous centers P3 of the two third sub-pixels 03 in the other group; for any two adjacent third sub-pixel groups 04 along the extension direction of the second diagonal T2 in the virtual frame 2, the line connecting the third luminous centers P3 of the two third sub-pixels 03 in one group is perpendicular to the line connecting the third luminous centers P3 of the two third sub-pixels 03 in the other group.

[0091] For any third sub-pixel group 04, denoted as the central third sub-pixel group, it has four nearest third sub-pixel groups 04. For the four nearest third sub-pixel groups 04, the line connecting the two third light-emitting centers P3 in each third sub-pixel group 04 is parallel to each other and perpendicular to the line connecting the two third light-emitting centers P3 in the central third sub-pixel group.

[0092] In some embodiments, in the arrangement of the third sub-pixel 03 shown in FIG3, the third sub-pixel 03 and a group of first sub-pixels 01 and second sub-pixels 02 that are closest to the third light-emitting center P3 of the third sub-pixel 03 constitute a pixel unit.

[0093] As shown in Figure 3, the display panel includes multiple pixel units. Each pixel unit includes a first sub-pixel 01, a second sub-pixel 02, and a third sub-pixel 03. That is, the two third sub-pixels 03 in the same group of third sub-pixels 04 belong to different pixel units. For any pixel unit, the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03 are arranged adjacent to each other; and the orthographic projection of the first light-emitting center P1 of the first sub-pixel 01 on the substrate 1 and the orthographic projection of the second light-emitting center P2 of the second sub-pixel 02 on the substrate 1 are both located on the same first center line L1.

[0094] In this context, the first center line L1 is the line connecting the center points of the adjacent two sides of the virtual frame 2. Here, the virtual frame 2 refers to the virtual frame 2 where the corresponding pixel unit is located. Specifically, as shown in Figure 7, the first center line L1 includes four lines: the line connecting the center point E of the first side 21 to the center point F of the second side 22, the line connecting the center point F of the second side 22 to the center point G of the third side 23, the line connecting the center point E of the first side 21 to the center point H of the fourth side 24, and the line connecting the center point G of the third side 23 to the center point H of the fourth side 24.

[0095] For any pixel unit, the distances from the first light-emitting center P1 and the second light-emitting center P2 to the third light-emitting center P3 of the third sub-pixel 03 are equal.

[0096] For example, for any virtual frame 2, the first light-emitting center P1 of any first sub-pixel 01 and the second light-emitting center P2 of any second sub-pixel 02 contained therein are both located on the first center line L1 of the virtual frame 2.

[0097] As shown in Figure 3, the virtual frame 2 includes two complete pixel units. A virtual frame 2 contains a third sub-pixel 03 corresponding to the two pixel units, and a first sub-pixel 01 and a second sub-pixel 02 corresponding to the four pixel units.

[0098] In some embodiments, as shown in FIG3, for the pixel unit where the third sub-pixel group 04 of the even-numbered column is located, the orthographic projection of the first light-emitting center P1 on the substrate 1 and the orthographic projection of the second light-emitting center P2 on the substrate 1 are symmetrically arranged with the second diagonal T2 as the axis of symmetry; the orthographic projection of the third light-emitting center P3 of the third sub-pixel 03 on the substrate 1 is located on the second diagonal T2. For the pixel unit where the third sub-pixel group 04 of the odd-numbered column is located, the orthographic projection of the first light-emitting center P1 on the substrate 1 and the orthographic projection of the second light-emitting center P2 on the substrate 1 are symmetrically arranged with the first diagonal T1 as the axis of symmetry; the orthographic projection of the third light-emitting center P3 of the third sub-pixel 03 on the substrate 1 is located on the first diagonal T1 in the virtual frame 2.

[0099] Optionally, as shown in Figure 3, for the pixel unit containing the third sub-pixel group 04 in the even-numbered column, the orthographic projection of the first sub-pixel 01 on the substrate 1 and the orthographic projection of the second sub-pixel 02 on the substrate 1 are symmetrically arranged with the second diagonal T2 as the axis of symmetry; the orthographic projection of the third sub-pixel 03 on the substrate 1 is symmetrically arranged with the second diagonal T2 in the virtual frame 2 containing the third sub-pixel 03 as the axis of symmetry. For the pixel unit containing the third sub-pixel group 04 in the odd-numbered column, the orthographic projection of the first sub-pixel 01 on the substrate 1 and the orthographic projection of the second sub-pixel 02 on the substrate 1 are symmetrically arranged with the first diagonal T1 as the axis of symmetry; the orthographic projection of the third sub-pixel 03 on the substrate 1 is symmetrically arranged with the first diagonal T1 in the virtual frame 2 containing the third sub-pixel 03 as the axis of symmetry.

[0100] Figure 8 is a schematic diagram of the distribution of luminous white dots in the pixel arrangement shown in Figure 3. In some embodiments, as shown in Figure 8, for three pixel units arranged side by side in the row direction X or column direction Y, the line connecting the luminous white dots W of one group of adjacent pixel units is the second connecting line F2, and the line connecting the luminous white dots W of another group of adjacent pixel units is the third connecting line F3; the included angle α between the second connecting line F2 and the third connecting line F3 is between 160° and 175°. For example, the included angle α between the second connecting line F2 and the third connecting line F3 is 167°.

[0101] It should be noted that the luminous white dot W is located on the line connecting the luminous center P2 of the first sub-pixel 01 and the luminous center P2 of the second sub-pixel 02 in the same pixel unit, and is closer to the 1 / 3 position of the luminous center P2 of the second sub-pixel 02.

[0102] As shown in Figure 8, the virtual broken line formed by connecting the light-emitting white dots W of each pixel unit in the row direction X and column direction Y is approximately a straight line. It can be seen that the pixel arrangement structure corresponding to Embodiment 1 is beneficial to reducing the jaggedness of the displayed image.

[0103] In some embodiments, as shown in FIG5, for any third sub-pixel group 04, the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically arranged with a second center line L2 as the axis of symmetry; the second center line L2 is the line connecting the center points of the two opposite sides in the virtual frame 2.

[0104] As shown in Figure 7, the second center line L2 is a straight line connecting the center point F of the second side 22 and the center point H of the fourth side 24. The third center line L3 is a straight line connecting the center point E of the first side 21 and the center point G of the third side 23.

[0105] Figure 6 shows the case where the third sub-pixel group 04 in Figure 5 is rotated by 90°. At this time, for any third sub-pixel group 04, the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically arranged with a third center line L3 as the axis of symmetry.

[0106] As shown in Figures 5 and 6, the extension direction of each third sub-pixel 03 is parallel to the line L2 connecting the second centers. For each third sub-pixel group 04, the line connecting the third emitting centers P3 of the two third sub-pixels 03 is parallel to each other.

[0107] In some embodiments, in the arrangement of the third sub-pixel 03 shown in FIG. 5, the third sub-pixel 03 and a group of first sub-pixels 01 and second sub-pixels 02 most adjacent to the third light-emitting center P3 of the third sub-pixel 03 constitute a pixel unit. Similarly, in the arrangement of the third sub-pixel 03 shown in FIG. 6, the third sub-pixel 03 and a group of first sub-pixels 01 and second sub-pixels 02 most adjacent to the third light-emitting center P3 of the third sub-pixel 03 constitute a pixel unit.

[0108] As shown in Figure 5, the display panel includes multiple pixel units. Each pixel unit includes a first sub-pixel 01, a second sub-pixel 02, and a third sub-pixel 03. That is, the two third sub-pixels 03 in the same group of third sub-pixels 04 belong to different pixel units. For any pixel unit, the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03 are arranged adjacent to each other; and the first line F1 connecting the first light-emitting center P1 of the first sub-pixel 01 and the second light-emitting center P2 of the second sub-pixel 02 is parallel to the second center line L2; the third light-emitting center P3 of the third sub-pixel 03 is located on a third center line L3. The third center line L3 is the line connecting the midpoint of the third line F3 and the midpoint of the second center line L2.

[0109] As shown in Figure 6, for any pixel unit, the first sub-pixel 01, the second sub-pixel 02 and the third sub-pixel 03 are arranged adjacent to each other; and the first line F1 connecting the first light-emitting center P1 of the first sub-pixel 01 and the second light-emitting center P2 of the second sub-pixel 02 is parallel to the third center line L3; the third light-emitting center P3 of the third sub-pixel 03 is located on a second center line L2.

[0110] As shown in Figures 5 and 6, for any pixel unit, the distances from the first light-emitting center P1 and the second light-emitting center P2 to the third light-emitting center P3 of the third sub-pixel 03 are equal.

[0111] Optionally, as shown in Figure 5, for any pixel unit, the orthographic projection of the first emitting center P1 of the first sub-pixel 01 onto the substrate 1 and the orthographic projection of the second emitting center P2 of the second sub-pixel 02 onto the substrate 1 are symmetrically arranged with the third center line L3 in the virtual frame 2 where the pixel unit is located as the axis of symmetry. Optionally, as shown in Figure 6, for any pixel unit, the orthographic projection of the first emitting center P1 of the first sub-pixel 01 onto the substrate 1 and the orthographic projection of the second emitting center P2 of the second sub-pixel 02 onto the substrate 1 are symmetrically arranged with the second center line L2 in the virtual frame 2 where the pixel unit is located as the axis of symmetry.

[0112] Optionally, as shown in Figure 5, for any pixel unit, the orthographic projection of the first sub-pixel 01 on the substrate 1 and the orthographic projection of the second sub-pixel 02 on the substrate 1 are symmetrically arranged with the third center line L3 in the virtual frame 2 where the pixel unit is located as the axis of symmetry. Optionally, as shown in Figure 6, for any pixel unit, the orthographic projection of the first sub-pixel 01 on the substrate 1 and the orthographic projection of the second sub-pixel 02 on the substrate 1 are symmetrically arranged with the second center line L2 in the virtual frame 2 where the pixel unit is located as the axis of symmetry.

[0113] Optionally, as shown in FIG5, the orthographic projection of the third sub-pixel 03 on the substrate 1 is symmetrically arranged with respect to the third center line L3 in the virtual frame 2 where the third sub-pixel 03 is located as the axis of symmetry. Optionally, as shown in FIG6, the orthographic projection of the third sub-pixel 03 on the substrate 1 is symmetrically arranged with respect to the second center line L2 in the virtual frame 2 where the third sub-pixel 03 is located as the axis of symmetry.

[0114] Figure 9 is a schematic diagram of the distribution of luminous white dots in the pixel arrangement shown in Figure 5. In some embodiments, as shown in Figure 9, for three pixel units arranged side by side in the row direction X or column direction Y, the line connecting the luminous white dots W of one group of adjacent pixel units is the second connecting line F2, and the line connecting the luminous white dots W of another group of adjacent pixel units is the third connecting line F3; the included angle α between the second connecting line F2 and the third connecting line F3 is between 160° and 175°. For example, the included angle α between the second connecting line F2 and the third connecting line F3 is 167°.

[0115] As shown in Figure 9, the virtual broken lines formed by connecting the luminous white dots W of each pixel unit in the row direction X and column direction Y have relatively small undulations. This demonstrates that the pixel arrangement structure corresponding to Embodiment 2 is beneficial in reducing the jagged edges of the displayed image. Similarly, the distribution of the luminous white dots W in the pixel arrangement of Embodiment 3 is similar to that of Embodiment 2, and the repeated parts will not be described again.

[0116] In some embodiments, as shown in Figures 3, 5 and 6, the outline shape of the third sub-pixel 03 on the substrate 1 includes a pattern formed by an arcuate portion and straight edges.

[0117] Figure 10a is a schematic diagram of one third sub-pixel shape provided in an embodiment of the present disclosure, and Figure 10b is a schematic diagram of another third sub-pixel shape provided in an embodiment of the present disclosure. Optionally, as shown in Figure 10a, the outline shape of the orthogonal projection of the third sub-pixel 03 on the substrate 1 is a semi-circle. As shown in Figure 10b, the outline shape of the orthogonal projection of the third sub-pixel 03 on the substrate 1 is a semi-ellipse with its major axis as the base.

[0118] In some embodiments, as shown in Figures 3, 5 and 6, the outline shape of the third sub-pixel 03 on the substrate 1 includes a pattern formed by multiple arcuate portions and straight edges, and at least two arcuate portions have the same angle.

[0119] Figure 10c is a schematic diagram of another third sub-pixel shape provided in the embodiment of this disclosure. As shown in Figure 10, the outline shape of the third sub-pixel 03 on the substrate 1 includes a pattern formed by a first arc segment S1, a second arc segment S2, a third arc segment S3 and a first straight line segment S4 connected end to end, wherein the first arc segment S1 and the third arc segment S3 have the same angle.

[0120] The shape of the third sub-pixel 03 provided in this disclosure is spliced ​​together to form an approximate circle, which helps to improve the color separation phenomenon caused by optical diffraction in the product process and enhance the display effect.

[0121] In some embodiments, as shown in Figures 3, 5, and 6, the two third sub-pixels 03 in the third sub-pixel group 04 are both located in the same third material evaporation area 33. The center of the third material evaporation area 33 is the center point of the line connecting the third light-emitting centers P3 of the two third sub-pixels 03, which is also the first center O of the virtual frame 2 corresponding to the third sub-pixel group 04.

[0122] In some embodiments, as shown in Figures 2, 3, 5 and 6, the pixel driving circuits corresponding to the two third sub-pixels 03 in the third sub-pixel group 04 are different, so they can be lit up separately to control different pixel units.

[0123] Optionally, due to process limitations imposed by the spacing between the pixel definition layer (PDL) and the anode pattern, the spacing between any two adjacent third sub-pixels (03) in the third sub-pixel group (04) is not less than 5 μm. For the third sub-pixel group (04), the spacing between any two adjacent third sub-pixels (03) is between 5 μm and 20 μm.

[0124] In some embodiments, as shown in Figures 3, 5 and 6, the light-emitting area corresponding to the light-emitting region of the third sub-pixel 03 is greater than the light-emitting area corresponding to the light-emitting region of the first sub-pixel 01; and / or, the light-emitting area corresponding to the light-emitting region of the third sub-pixel 03 is greater than the light-emitting area corresponding to the light-emitting region of the second sub-pixel 02.

[0125] Here, the area ratio of the sub-pixels can be determined based on the luminous efficiency and lifespan of the luminescent organic materials of the three color sub-pixels. For example, the blue light pixel has the shortest lifespan, so the third sub-pixel 03 is set to have a larger luminescent area, thereby suppressing the reduction of the display panel's lifespan and improving the display panel's lifespan.

[0126] The above-mentioned disclosure lists four different symmetry axes of the third sub-pixel group 04, namely ±45°, 90° and 0°. Other directions will not be described in detail here.

[0127] Figure 11 is a schematic diagram of the display panel according to Embodiment 4 of this disclosure. In some embodiments, as shown in Figure 11, the third sub-pixel group 04 includes four third sub-pixels 03; the orthographic projections of the four third sub-pixels 03 on the substrate 1 are arranged in a circular array with the first center O as the center.

[0128] The four third sub-pixels 03 are arranged in a circular array. The third light-emitting centers P3 of the two adjacent third sub-pixels 03 along the surrounding direction are perpendicular to the lines connecting the first center O.

[0129] In this embodiment, the four third sub-pixels 03 are arranged in a circular array, and the specific positions of the four third sub-pixels 03 in the surrounding direction are not limited, that is, any position can be selected.

[0130] However, as the positions of the four third sub-pixels 03 change in the surrounding direction, the positions of the third light-emitting center P3 of the third sub-pixels 03 before and after the change are different. The first sub-pixel 01 and the second sub-pixel 02 that together with the third sub-pixel 03 constitute the pixel unit may be different. This disclosure only uses one example, namely embodiment 4, as an example for detailed description. The same applies to other positions, and will not be repeated.

[0131] Figure 12 is an enlarged schematic diagram of a single third sub-pixel group in Figure 11. In some embodiments, as shown in Figure 12, for any three third sub-pixels 03 in a third sub-pixel group 04, two groups of third sub-pixel sub-groups 041 are arranged side by side along the row direction X, and each group of third sub-pixel sub-groups 041 includes two third sub-pixels 03 arranged side by side along the column direction Y.

[0132] As shown in Figure 11, the third sub-pixel 03 in the two groups of third sub-pixel subgroups 041 is symmetrically set with the line connecting the center point F of the second side 22 and the center point H of the fourth side 24 as the axis of symmetry.

[0133] As shown in Figure 11, the two third sub-pixels 03 in the same group of third sub-pixel subgroup 041 are symmetrically set with the line connecting the center point E of the first side 21 and the center point G of the third side 23 as the axis of symmetry.

[0134] In some embodiments, in the arrangement of the third sub-pixel 03 shown in FIG11, there are two third sub-pixels 03 and a group of first sub-pixels 01 and second sub-pixels 02 that are closest to the third light-emitting center P3 of the two third sub-pixels 03, which constitute a pixel unit.

[0135] As shown in Figure 11, the display panel includes multiple pixel units. Each pixel unit includes a first sub-pixel 01, a second sub-pixel 02, and two third sub-pixels 03, with the two third sub-pixels 03 respectively adjacent to the first sub-pixel 01 and the second sub-pixel 02. The two third sub-pixels 03 are located in different third sub-pixel groups 04. For any pixel unit, the first light-emitting center P1 of the first sub-pixel 01 and the second light-emitting center P2 of the second sub-pixel 02 are both located on the same first center line L1. The first center line L1 is the line connecting the center points of the adjacent two sides of the virtual frame 2.

[0136] As shown in Figure 11, for any pixel unit, the distances from the first light-emitting center P1 and the second light-emitting center P2 to the third light-emitting center P3 of any third sub-pixel 03 are equal.

[0137] For example, for any virtual frame 2, the first light-emitting center P1 of any first sub-pixel 01 and the second light-emitting center P2 of any second sub-pixel 02 contained therein are both located on the first center line L1 of the virtual frame 2.

[0138] It should be noted that, as shown in Figure 11, the four third sub-pixels 03 in the same group of third sub-pixels 04 belong to different pixel units. The virtual frame 2 includes four complete pixel units.

[0139] Optionally, as shown in Figure 11, for any pixel unit, the line connecting the first light-emitting center P1 of the first sub-pixel 01 and the second light-emitting center P2 of the second sub-pixel 02 is perpendicular to the line connecting the third light-emitting centers P3 of the two third sub-pixels 03.

[0140] In some embodiments, as shown in FIG11, for the pixel unit where the third sub-pixel group 04 of the even-numbered column is located, the orthographic projection of the first light-emitting center P1 on the substrate 1 and the orthographic projection of the second light-emitting center P2 on the substrate 1 are symmetrically arranged with the second diagonal T2 as the axis of symmetry; the orthographic projection of the third light-emitting center P3 of the two third sub-pixels 03 on the substrate 1 is located on the second diagonal T2. For the pixel unit where the third sub-pixel group 04 of the odd-numbered column is located, the orthographic projection of the first light-emitting center P1 on the substrate 1 and the orthographic projection of the second light-emitting center P2 on the substrate 1 are symmetrically arranged with the first diagonal T1 as the axis of symmetry; the orthographic projection of the third light-emitting center P3 of the two third sub-pixels 03 on the substrate 1 is located on the first diagonal T1 in the virtual frame 2.

[0141] Optionally, as shown in Figure 11, for pixel units containing the third sub-pixel group 04 in even-numbered columns, the orthographic projections of the first sub-pixel 01 and the second sub-pixel 02 on the substrate 1 are symmetrically arranged about the second diagonal T2 as the axis of symmetry; the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically arranged about the first center line L1 within the region where the pixel unit is located as the axis of symmetry; and the orthographic projection of a single third sub-pixel 03 on the substrate 1 is symmetrically arranged about the second diagonal T2 as the axis of symmetry. For pixel units containing the third sub-pixel group 04 in odd-numbered columns, the orthographic projections of the first sub-pixel 01 and the second sub-pixel 02 on the substrate 1 are symmetrically arranged about the first diagonal T1 as the axis of symmetry; the orthographic projections of the two third sub-pixels 03 on the substrate 1 are symmetrically arranged about the first center line L1 within the region where the pixel unit is located as the axis of symmetry; and the orthographic projection of a single third sub-pixel 03 on the substrate 1 is symmetrically arranged about the first diagonal T1 as the axis of symmetry.

[0142] Figure 13 is a schematic diagram of the distribution of luminous white dots in the pixel arrangement shown in Figure 11. In some embodiments, as shown in Figure 13, for three pixel units arranged side by side in the row direction X or column direction Y, the line connecting the luminous white dots W of one group of adjacent pixel units is the second connecting line F2, and the line connecting the luminous white dots W of another group of adjacent pixel units is the third connecting line F3; the included angle α between the second connecting line F2 and the third connecting line F3 is between 160° and 175°. For example, the included angle α between the second connecting line F2 and the third connecting line F3 is 167°.

[0143] As shown in Figure 13, the virtual broken line formed by connecting the light-emitting white dots W of each pixel unit in the row direction X and column direction Y is approximately a straight line. It can be seen that the pixel arrangement structure corresponding to Embodiment 4 is beneficial to reducing the jaggedness of the displayed image.

[0144] In some embodiments, FIG14 is a schematic diagram of the display panel of Embodiment 5 of the present disclosure. FIG15 is a schematic diagram of the display panel of Embodiment 6 of the present disclosure. In some embodiments, as shown in FIG14 and FIG15, the arrangement of sub-pixels is the same as in Embodiment 4, but the pixel units composed of sub-pixels are different.

[0145] In the arrangement of the third sub-pixel 03 shown in Figure 11, there are two third sub-pixels 03 and a group of first sub-pixels 01 and second sub-pixels 02 that are closest to the third light-emitting center P3 of the two third sub-pixels 03, which constitute a pixel unit.

[0146] As shown in Figure 14, the display panel includes multiple pixel units. Each pixel unit includes a first sub-pixel 01, a second sub-pixel 02, and two third sub-pixels 03. The two third sub-pixels 03 are located in the same third sub-pixel subgroup 041. For any pixel unit, the first line F1 connecting the first light-emitting center P1 of the first sub-pixel 01 and the second light-emitting center P2 of the second sub-pixel 02 is parallel to the second center line L2 in the virtual frame 2. The third light-emitting centers P3 of the two sub-pixels 03 are located on the first diagonal T1 and the second diagonal T2 in the virtual frame 2, respectively.

[0147] Alternatively, as shown in Figure 15, the display panel includes multiple pixel units. Each pixel unit includes a first sub-pixel 01, a second sub-pixel 02, and two third sub-pixels 03. The two third sub-pixels 03 are located in different third sub-pixel subgroups 041. For any pixel unit, the first line F1 connecting the first light-emitting center P1 of the first sub-pixel 01 and the second light-emitting center P2 of the second sub-pixel 02 is parallel to the third center line L3 in the virtual frame 2. The third light-emitting centers P3 of the two sub-pixels 03 are located on the first diagonal T1 and the second diagonal T2 in the virtual frame 2, respectively.

[0148] The distribution of luminous white dots in the pixel arrangement shown in Figure 14 is the same as that in Figure 9, and the repeated parts will not be described again. The distribution of luminous white dots in the pixel arrangement shown in Figure 15 is similar to that in Figure 14, and the repeated parts will not be described again.

[0149] In some embodiments, as shown in FIG12, the outline shape of the third sub-pixel 03 on the substrate 1 includes a symmetrical pattern formed by multiple arcuate portions and multiple straight edges, and at least two arcuate portions have the same angle. For example, it may include rounded fan shapes, etc.

[0150] Figure 16 is a schematic diagram of another third sub-pixel shape provided in an embodiment of this disclosure. Optionally, as shown in Figure 16, the outline shape of the orthographic projection of the third sub-pixel 03 on the substrate 1 is a rounded sector, specifically including a second straight line S5, a fourth arc segment S6, a fifth arc segment S7, a sixth arc segment S8, and a third straight line S9 connected end to end. The corner formed by the connection of the second straight line S5 and the third straight line S9 is a rounded corner or a chamfered corner. For example, the fourth arc segment S6 and the sixth arc segment S8 correspond to the same angle.

[0151] In this embodiment, the shapes of the four third sub-pixels 03 in a group of third sub-pixels 04 are pieced together to form an approximate circle, which helps to improve the color separation phenomenon caused by optical diffraction in the product process and enhance the display effect. At the same time, a single rounded fan-shaped element is also approximately circular, which similarly helps to improve the color separation phenomenon caused by optical diffraction in the product process.

[0152] Of course, the shape of the third sub-pixel 03 of this disclosure includes, but is not limited to, the types listed above. While improving color separation, it can also be set to shapes such as circles, hexagons, and octagons, which will not be listed here. For those skilled in the art, various modifications and improvements can be made to the shape of the third sub-pixel 03 without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered within the scope of protection of this disclosure.

[0153] In some embodiments, the first sub-pixel 01 and the second sub-pixel 02 have the same shape and size.

[0154] In some embodiments, the light-emitting area of ​​the first sub-pixel 01 is smaller than the light-emitting area of ​​the second sub-pixel 02.

[0155] In some embodiments, as shown in Figures 3, 5, 6, and 11, the outline shape of the orthographic projection of the first sub-pixel 01 on the substrate 1 and the outline shape of the orthographic projection of the second sub-pixel 02 on the substrate 1 are both circular, thereby improving the color separation phenomenon caused by optical diffraction in the product process and enhancing the display effect.

[0156] In some embodiments, as shown in FIG12, for any pixel unit, the sum of the light-emitting areas corresponding to the light-emitting regions of the two third sub-pixels 03 is greater than the light-emitting area corresponding to the light-emitting region of the first sub-pixel 01; and / or, the sum of the light-emitting areas corresponding to the light-emitting regions of the two third sub-pixels 03 is greater than the light-emitting area corresponding to the light-emitting region of the second sub-pixel 02.

[0157] Here, the area ratio of the sub-pixels can be determined based on the luminous efficiency and lifespan of the luminescent organic materials of the three color sub-pixels. For example, the blue light pixel has the shortest lifespan, so the third sub-pixel 03 is set to have a larger luminescent area, thereby suppressing the reduction of the display panel's lifespan and improving the display panel's lifespan.

[0158] It should be noted that the light-emitting devices involved in the embodiments of this disclosure may include, but are not limited to, organic light-emitting diodes (OLEDs), quantum dot light-emitting diodes (QLEDs), or micro light-emitting diodes (Micro LEDs). Optionally, the light-emitting device is an OLED device. The display panel is an OLED display panel.

[0159] The above is a complete description of the display panel of the embodiments of this disclosure.

[0160] The pixel arrangement structure provided in this embodiment features a densely packed sub-pixels with no wasted space. Compared to conventional pixel arrangements (Figure 4), the effective light-emitting area of ​​the pixels is increased by approximately 20%, effectively improving the display panel's brightness and lifespan. Simultaneously, the light-emitting areas of the first sub-pixel 01 and the second sub-pixel 02 are circular, and the splicing shape of multiple third sub-pixels 03 in the same group of third sub-pixels 04 is approximately circular, reducing color separation issues caused by optical diffraction in the COE process. Furthermore, when displaying white light, the white light-emitting points W formed by each pixel unit are approximately aligned on the same straight line in the row direction X and column direction Y, effectively improving the jagged edge effect during display.

[0161] In addition, this disclosure also provides a display device, which includes the display panel described in any of the above embodiments.
