[0135] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0136] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0137] When describing positional relationships, unless otherwise specified, when an element, such as a layer, film, or substrate, is referred to as being "on" another element, it can be directly on the other element or intervening elements may exist. Furthermore, when a layer is referred to as being "under" another layer, it can be directly below or one or more light-emitting units may exist. It is also understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or one or more light-emitting units may exist.

[0138] In the case of using “including,” “having,” and “comprising” described herein, another component may be added unless a clear limiting term such as “only,” “consisting of,” etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as having one number.

[0139] It should be understood that although the terms "first," "second," etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this application.

[0140] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately," "approximately," or "substantially" can mean within one or more standard deviations, and is not limited here.

[0141] Furthermore, in the specification, the phrase “planar distribution diagram” refers to a drawing when the target portion is viewed from above, and the phrase “cross-sectional diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0142] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0143] The pixel arrangement structure directly determines the display effect of the display panel. To ensure uniform display, the light-emitting units are usually arranged as evenly as possible along the row and column directions in a certain pattern. When the display panel displays a white image, problems such as color cast and color fringing are prone to occur, affecting the display effect of the display panel.

[0144] Based on the above technical problems, the embodiments of the present application provide a display panel and a display device, wherein a pixel arrangement unit includes at least one pixel unit, and the pixel unit has multiple light-emitting units, the multiple light-emitting units include a first light-emitting unit, a second light-emitting unit, a third light-emitting unit and a fourth light-emitting unit, the first light-emitting unit, the second light-emitting unit and the third light-emitting unit are respectively used to emit light of different colors; the third light-emitting unit and the fourth light-emitting unit are used to emit light of the same color; in the same pixel unit, at least part of the first light-emitting unit and the third light-emitting unit are arranged along the first direction, and at least part of the first light-emitting unit and the fourth light-emitting unit are arranged along the second direction; at least part of the second light-emitting unit and the third light-emitting unit are arranged along the second direction; at least part of the second light-emitting unit and the fourth light-emitting unit are arranged along the first direction; the first light-emitting unit and the second light-emitting unit are arranged along the third direction; the first direction, the second direction and the third direction intersect each other; wherein, in two pixel units adjacent to each other along the first direction, the first light-emitting unit in one pixel unit is located on one side of the second light-emitting unit in the other pixel unit along the first direction and is adjacently arranged, and the fourth light-emitting unit in one pixel unit is located on one side of the third light-emitting unit in the other pixel unit along the first direction and is adjacently arranged. In this way, at least part of the first light-emitting unit, at least part of the second light-emitting unit, the third light-emitting unit, and the fourth light-emitting unit in two adjacent pixel units can be arranged in a row along the first direction. In other words, the light-emitting units emitting three different colors of light can be arranged in a row along the first direction. In this way, the color cast and color fringing problems of the display panel in the first direction can be improved, thereby improving the display effect of the display panel.

[0145] See Figures 1 to 5 、 Figures 9 to 12 As shown, in a first aspect, an embodiment of the present application provides a display panel 10, which may be an organic light emitting diode display panel (Organic Light Emitting Diode, referred to as OLED) or a quantum dot electroluminescent display panel (Quantum Dot Light Emitting Diodes, referred to as QLED).

In this way, the light-emitting units 121 in the pixel arrangement structure can be arranged more evenly, which is beneficial to improving the display effect of the display panel 10.

[0148] In two pixel units 12a adjacent to each other along the first direction X, the first light-emitting unit 121a in one pixel unit 12a is located on one side of the second light-emitting unit 121b in the other pixel unit 12a along the first direction X and is adjacent to each other, and the fourth light-emitting unit 121d in one pixel unit 12a is located on one side of the third light-emitting unit 121c in the other pixel unit 12a along the first direction X and is adjacent to each other. In this way, at least a portion of the first light-emitting unit 121a, at least a portion of the second light-emitting unit 121b, the third light-emitting unit 121c, and the fourth light-emitting unit 121d in the two adjacent pixel units 12a can be arranged in a row along the first direction X.

In other words, the light-emitting units 121 emitting three different colors of light can be arranged in a row along the first direction X. In this way, the color cast and color fringing problems of the display panel 10 along the first direction X can be improved, thereby improving the display effect of the display panel 10.

[0150] In one embodiment, see Figure 2 As shown, in two pixel units 12a adjacent to each other along the second direction Y, the first light-emitting unit 121a in one pixel unit 12a is located on one side of the second light-emitting unit 121b in the other pixel unit 12a along the second direction Y and is adjacent to each other; the third light-emitting unit 121c in one pixel unit 12a is located on one side of the fourth light-emitting unit 121d in the other pixel unit 12a along the second direction Y and is adjacent to each other.

In this way, the color cast and color fringing problems of the display panel 10 along the second direction Y can be improved, and the display effect of the display panel 10 can be significantly improved.

[0152] Optionally, see Figure 3 and Figure 10 As shown, the plurality of pixel arrangement units 12 are arranged in rows along the first direction X and in columns along the second direction Y.

[0153] In this way, the plurality of pixel arrangement units 12 can be arranged more evenly, thereby facilitating improved display effects of the display panel 10 .

[0183] In one embodiment, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12As shown, in all pixel arrangement units 12, all third light-emitting units 121c are arranged along the first direction X to form a plurality of third light-emitting unit rows, and the plurality of third light-emitting unit rows are arranged sequentially along the second direction Y; the third light-emitting unit rows located in odd rows and the third light-emitting unit rows located in even rows are staggered along the first direction X; and the third light-emitting units 121c in the third light-emitting unit rows located in odd rows and the third light-emitting unit 121c in the third light-emitting unit rows located in even rows are alternately arranged along the first direction X.

[0184] In this way, the third light emitting units 121 c in all pixel arrangement units 12 can be arranged more evenly, thereby reducing the probability of color shift of the display panel 10 , improving the stripe effect when the display panel 10 displays pure colors, and enhancing the display effect of the display panel 10 .

[0185] Optionally, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12 As shown, the structure of each third light emitting unit 121c in the odd-numbered rows after the third light emitting unit rows are rotated 90° is the same as the structure of each third light emitting unit 121c in the even-numbered rows.

[0186] Optionally, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12 As shown, in all pixel arrangement units 12, all third light-emitting units 121c are arranged along the second direction Y to form a plurality of third light-emitting unit columns, and the plurality of third light-emitting unit columns are arranged sequentially along the first direction X; the third light-emitting unit columns located in odd columns and the third light-emitting unit columns located in even columns are staggered along the second direction Y; and the third light-emitting units 121c in the third light-emitting unit columns located in odd columns and the third light-emitting unit 121c in the third light-emitting unit columns located in even columns are alternately arranged along the second direction Y.

[0187] In this way, the third light emitting units 121 c in all pixel arrangement units 12 can be arranged more evenly, thereby reducing the probability of color shift of the display panel 10 , improving the stripe effect when the display panel 10 displays pure colors, and enhancing the display effect of the display panel 10 .

[0188] Optionally, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12 As shown, after the third light emitting units 121 c in the odd-numbered columns are rotated 90°, the structure of each third light emitting unit 121 c is the same as the structure of each third light emitting unit 121 c in the even-numbered columns.

[0189] In one embodiment, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12 As shown, in all pixel arrangement units 12, all fourth light-emitting units 121d are arranged along the first direction X to form a plurality of fourth light-emitting unit rows, and the plurality of fourth light-emitting unit rows are sequentially arranged along the second direction Y; the fourth light-emitting unit rows located in odd rows and the fourth light-emitting unit rows located in even rows are staggered along the first direction X; and the fourth light-emitting units 121d in the fourth light-emitting unit rows located in odd rows and the fourth light-emitting units 121d in the fourth light-emitting unit rows located in even rows are alternately arranged along the first direction X.

[0190] In this way, the fourth light emitting units 121d in all pixel arrangement units 12 can be arranged more evenly, thereby reducing the probability of color shift of the display panel 10, improving the stripe effect when the display panel 10 displays pure colors, and enhancing the display effect of the display panel 10.

[0191] Optionally, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12 As shown, the structure of each fourth light emitting unit 121d in the odd-numbered rows after the fourth light emitting unit row is rotated 90° is the same as the structure of each fourth light emitting unit 121d in the even-numbered rows.

[0192] Optionally, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12 As shown, in all pixel arrangement units 12, all fourth light-emitting units 121d are arranged along the second direction Y to form a plurality of fourth light-emitting unit columns, and the plurality of fourth light-emitting unit columns are arranged sequentially along the first direction X; the fourth light-emitting unit columns located in odd columns and the fourth light-emitting unit columns located in even columns are staggered along the second direction Y; and the fourth light-emitting units 121d in the fourth light-emitting unit columns located in odd columns and the fourth light-emitting unit 121d in the fourth light-emitting unit columns located in even columns are alternately arranged along the second direction Y.

[0193] In this way, the fourth light emitting units 121d in all pixel arrangement units 12 can be arranged more evenly, thereby reducing the probability of color shift of the display panel 10, improving the stripe effect when the display panel 10 displays pure colors, and enhancing the display effect of the display panel 10.

[0194] Optionally, see Figure 3 、 Figure 5 、 Figure 10 and Figure 12As shown, after the fourth light emitting unit columns located in odd columns are rotated 90°, the structure of each fourth light emitting unit 121d is the same as the structure of each fourth light emitting unit 121d in the fourth light emitting unit columns located in even columns.

[0195] In one embodiment, see Figure 2 、 Figure 3 、 Figures 9 to 11 As shown, each pixel arrangement unit 12 includes a plurality of pixel units 12a, and the plurality of pixel units 12a include a first pixel unit 12a1, a second pixel unit 12a2, a third pixel unit 12a3 and a fourth pixel unit 12a4; in the same pixel arrangement unit 12, the first pixel unit 12a1 and the second pixel unit 12a2 are arranged along the first direction X and are adjacent to each other; the third pixel unit 12a3 and the fourth pixel unit 12a4 are arranged along the first direction X and are adjacent to each other; the first pixel unit 12a1 and the third pixel unit 12a3 are arranged along the second direction Y and are adjacent to each other; and the second pixel unit 12a2 and the third pixel unit 12a3 are arranged along the second direction Y and are adjacent to each other.

[0196] In this way, the arrangement of the first light-emitting unit 121a, the second light-emitting unit 121b, the third light-emitting unit 121c and the fourth light-emitting unit 121d in the pixel arrangement unit 12 can be made more uniform and full, thereby improving the display stripe and granularity and enhancing the display effect of the display panel 10.

[0197] Optionally, see Figure 2 and Figure 3 As shown, in the first pixel unit 12a1, the first light-emitting unit 121a includes a first sub-portion 121a1 extending along the first direction X and a second sub-portion 121a2 extending along the second direction Y; the first sub-portion 121a1 and the third light-emitting unit 121c are arranged along the first direction X, and a portion of the first sub-portion 121a1 and the third light-emitting unit 121c are located on one side of the second light-emitting unit 121b along the second direction Y; the second sub-portion 121a2 and the fourth light-emitting unit 121d are arranged along the second direction Y, and a portion of the second sub-portion 121a2 and the fourth light-emitting unit 121d are located on one side of the second light-emitting unit 121b along the first direction X.

[0198] Optionally, see Figure 2 、 Figure 3 、 Figures 9 to 11As shown, the second light-emitting unit 121b in the first pixel unit 12a1 is adjacent to the second light-emitting unit 121b in the third pixel unit 12a3; the first light-emitting unit 121a in the first pixel unit 12a1 is located on the side of the second light-emitting unit 121b away from the third pixel unit 12a3; and the first light-emitting unit 121a in the third pixel unit 12a3 is located on the side of the second light-emitting unit 121b away from the first pixel unit 12a1.

[0199] In this way, the light-emitting units 121 that emit light of the same color in the first direction X or the second direction Y or the light-emitting units 121 that emit light of two different colors can be prevented from being arranged in a row alone, so that the light-emitting units 121 that emit light of three different colors in the first direction or the second direction can be arranged in a row, thereby significantly improving the display color shift and color fringing problems and improving the display effect of the display panel 10.

[0200] Optionally, see Figure 2 、 Figure 3 、 Figures 9 to 11 As shown, the first light-emitting unit 121a in the second pixel unit 12a2 is adjacent to the first light-emitting unit 121a in the fourth pixel unit 12a4; the second light-emitting unit 121b in the second pixel unit 12a2 is located on the side of the first light-emitting unit 121a away from the fourth pixel unit 12a4; the second light-emitting unit 121b in the fourth pixel unit 12a4 is located on the side of the first light-emitting unit 121a away from the second pixel unit 12a2.

[0201] In this way, the light-emitting units 121 that emit light of the same color in the first direction X or the second direction Y or the light-emitting units 121 that emit light of two different colors can be prevented from being arranged in a row alone, so that the light-emitting units 121 that emit light of three different colors in the first direction or the second direction can be arranged in a row, thereby significantly improving the display color shift and color fringing problems and improving the display effect of the display panel 10.

[0202] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, in the same pixel unit 12a, the structure of the third light-emitting unit 121c after being rotated 90° is the same as that of the fourth light-emitting unit 121d.

[0203] In this embodiment, the third light-emitting unit 121c and the fourth light-emitting unit 121d are used to emit light of the same color. By making the structure of the third light-emitting unit 121c rotated 90° in the same pixel unit 12a identical to the structure of the fourth light-emitting unit 121d, the third light-emitting unit 121c and the fourth light-emitting unit 121d in the first direction X and the third light-emitting unit 121c and the fourth light-emitting unit 121d in the second direction Y can be distributed more evenly, thereby improving the color deviation of the display panel 10 and enhancing the display effect of the display panel 10.

[0204] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, after the first pixel unit 12a1 is rotated 180°, the structure of each light-emitting unit 121 is mirror-imaged to the structure of each light-emitting unit 121 in the second pixel unit 12a2.

[0205] In this way, the light-emitting units 121 that emit light of the same color in the first direction X or the second direction Y or the light-emitting units 121 that emit light of two different colors can be prevented from being arranged in a single row. Instead, the light-emitting units 121 that emit light of three different colors in the first direction X or the second direction Y can be arranged in a row, thereby significantly improving the display color shift and color fringing problems and enhancing the display effect of the display panel 10.

[0206] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, after the second pixel unit 12a2 is rotated 180°, the structure of each light-emitting unit 121 is mirror-imaged to the structure of each light-emitting unit 121 in the third pixel unit 12a3.

[0207] In this way, the light-emitting units 121 that emit light of the same color in the first direction X or the second direction Y or the light-emitting units 121 that emit light of two different colors can be prevented from being arranged in a single row. Instead, the light-emitting units 121 that emit light of three different colors in the first direction X or the second direction Y can be arranged in a row, thereby significantly improving the display color shift and color fringing problems and enhancing the display effect of the display panel 10.

[0208] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, after the third pixel unit 12a3 is rotated 180°, the structure of each light-emitting unit 121 is mirror-imaged to the structure of each light-emitting unit 121 in the fourth pixel unit 12a1.

[0209] In this way, the light-emitting units 121 that emit light of the same color in the first direction X or the second direction Y or the light-emitting units 121 that emit light of two different colors can be prevented from being arranged in a single row. Instead, the light-emitting units 121 that emit light of three different colors in the first direction X or the second direction Y can be arranged in a row, thereby significantly improving the display color shift and color fringing problems and enhancing the display effect of the display panel 10.

[0210] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, after the fourth pixel unit 12a4 is rotated 180°, the structure of each light-emitting unit 121 is mirror-imaged to the structure of each light-emitting unit in the first pixel unit 12a1.

[0211] In this way, the light-emitting units 121 that emit light of the same color in the first direction X or the second direction Y or the light-emitting units 121 that emit light of two different colors can be prevented from being arranged in a single row. Instead, the light-emitting units 121 that emit light of three different colors in the first direction X or the second direction Y can be arranged in a row, thereby significantly improving the display color shift and color fringing problems and enhancing the display effect of the display panel 10.

[0212] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, the lines connecting the center of the first pixel unit 12a1, the center of the second pixel unit 12a2, the center of the third pixel unit 12a3 and the center of the fourth pixel unit 12a4 form a first virtual quadrilateral;

[0213] In this way, the arrangement of the first pixel unit 12a1, the second pixel unit 12a2, the third pixel unit 12a3 and the fourth pixel unit 12a4 in the pixel arrangement unit 12 can be compact and uniform, so that the distribution of the light-emitting unit 121 in the pixel arrangement structure is more uniform, thereby improving the display saturation of the display panel 10, and improving the display stripe and granularity, thereby significantly improving the display effect of the display panel 10.

[0214] It should be noted that the “center of the pixel unit 12 a ” may be understood as the center of a figure enclosed by the outer contours of the plurality of light-emitting units 121 in the pixel unit 12 a .

[0215] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, the structure of each light-emitting unit 121 after the first pixel unit 12a1 is rotated 180° is the same as the structure of each light-emitting unit 121 in the third pixel unit 12a3.

[0216] Optionally, see Figures 2 to 5 、 Figures 9 to 12As shown, the structure of each light-emitting unit 121 after the second pixel unit 12a2 is rotated 180° is the same as the structure of each light-emitting unit 121 in the fourth pixel unit 12a4.

[0217] Optionally, the first virtual quadrilateral is a rectangle.

[0218] Optionally, see Figures 2 to 5 、 Figures 9 to 12 As shown, after the first pixel unit 12a1 is rotated 90°, the structure of each light-emitting unit 121 is the same as the structure of each light-emitting unit 121 in the second pixel unit 12a2; after the third pixel unit 12a3 is rotated 90°, the structure of each light-emitting unit 121 is the same as the structure of each light-emitting unit 121 in the fourth pixel unit 12a4;

[0219] Optionally, the first virtual quadrilateral is a square;

[0220] Optionally, the first direction X is perpendicular to the second direction Y;

[0221] Optionally, the included angle between the third direction M and the first direction X is 45°, and the included angle between the third direction M and the second direction Y is 45°.

[0222] In one embodiment, see Figure 11 and Figure 12 As shown, the display panel 10 further includes at least one fifth light emitting unit 121 e ; the fifth light emitting unit 121 e is located between two adjacent pixel units 12 a along the third direction M.

[0223] It should be noted that the fifth light-emitting unit 121e can emit light of the same color as one of the first light-emitting unit 121a, the second light-emitting unit 121b, and the third light-emitting unit 121c. The fifth light-emitting unit 121e can be turned on synchronously with the first light-emitting unit 121a, the second light-emitting unit 121b, and the third light-emitting unit 121c, or can be turned on asynchronously. When the fifth light-emitting unit 121e is turned on synchronously with the first light-emitting unit 121a, the second light-emitting unit 121b, and the third light-emitting unit 121c, display brightness can be increased, and at the same brightness, the power consumption of the display panel 10 can be reduced. When the fifth light-emitting unit 121e is not turned on synchronously with the first light-emitting unit 121a, the second light-emitting unit 121b and the third light-emitting unit 121c, the fifth light-emitting unit 121e can be a backup light-emitting unit 121; for example, when highlight display is required, the fifth light-emitting unit 121e can be turned on to improve the display effect of the display panel 10; when one of the first light-emitting unit 121a, the second light-emitting unit 121b and the third light-emitting unit 121c does not emit light due to life degradation or manufacturing process, the fifth light-emitting unit 121e can be turned on, which can reduce the probability of color deviation of the display panel 10, improve the display quality of the display panel 10, and extend the service life of the display panel 10.

[0224] The fifth light-emitting unit 121e may also emit light of a different color from any of the first light-emitting unit 121a, the second light-emitting unit 121b and the third light-emitting unit 121c. For example, the fifth light-emitting unit 121e may be a white light-emitting unit 121. In this way, when the display panel 10 displays a white screen, the display brightness of the display panel 10 can be increased, and at the same brightness, the power consumption of the display panel 10 can be reduced.

[0225] In addition, when the outer contours of the plurality of light emitting units 121 in the pixel unit 12a form a circle, the fifth light emitting unit 121e is disposed between two adjacent pixel units 12a along the third direction M, thereby fully utilizing the space and improving the aperture ratio.

[0226] Optionally, see Figure 11 and Figure 12 As shown, the fifth light emitting unit 121e is located between two adjacent pixel units 12a in the fourth direction N, and the first direction X, the second direction Y, the third direction M and the fourth direction N intersect with each other.

[0227] In this way, the display effect can be improved and the display life can be extended.

[0228] Optionally, see Figure 11 and Figure 12 As shown, the display panel 10 includes a plurality of fifth light-emitting units 121e, one pixel arrangement unit 12 corresponds to four fifth light-emitting units 121e, and the lines connecting the centers of the four fifth light-emitting units 121e form a second virtual quadrilateral. One pixel unit 12a in the pixel arrangement unit 12 is located within the second virtual quadrilateral, and one fifth light-emitting unit 121e is located within the first virtual quadrilateral.

[0229] In this way, the arrangement of the plurality of pixel arrangement units 12 and the plurality of fifth light emitting units 121e can be made more uniform, thereby improving the display effect and extending the service life.

[0230] Optionally, see Figure 11 and Figure 12 As shown, the center of the first virtual quadrilateral coincides with the center of the fifth light emitting unit 121e located in the first virtual quadrilateral.

[0231] In this way, the arrangement of the plurality of pixel arrangement units 12 and the plurality of fifth light emitting units 121e can be made more compact, thereby improving space utilization, achieving a more delicate display effect, and extending service life.

[0232] Alternatively, see 11 and Figure 12 As shown, the center of the second virtual quadrilateral coincides with the center of the pixel unit 12a located in the second virtual quadrilateral.

[0233] In this way, the arrangement of the plurality of pixel arrangement units 12 and the plurality of fifth light emitting units 121e can be made more compact, thereby improving space utilization, achieving a more delicate display effect, and extending service life.

[0234] Optionally, see Figure 12 As shown, the plurality of fifth light emitting units 121e are arranged in rows along the first direction X and in columns along the second direction Y.

[0235] In this way, the arrangement of the plurality of fifth light-emitting units 121e can be made more uniform, thereby improving the display effect.

[0236] Optionally, the fifth light emitting unit 121 e is one of a red light emitting unit 121 , a blue light emitting unit 121 , a green light emitting unit 121 and a white light emitting unit 121 .

[0237] Optionally, the fifth light emitting unit 121e has the same color as the third light emitting unit 121c.

[0238] In this way, not only are there light-emitting units 121 that emit three different colors of light along the first direction X and the second direction Y, but there are also light-emitting units 121 that emit three different colors of light along the third direction M and the fourth direction N. In this way, the display color cast and color edge problems can be greatly improved, the resolution can be increased, and the display quality of the display panel 10 can be greatly improved.

[0239] Optionally, the included angle between the fourth direction N and the first direction X is 45°, and the included angle between the fourth direction N and the second direction Y is 45°.

[0240] In one embodiment, see Figure 9 and Figure 10 As shown, the display panel 10 further includes at least one light-transmitting reserved area A; the light-transmitting reserved area A is located between two adjacent pixel units 12 a along the third direction M.

[0241] In this way, the light transmittance of the display panel 10 can be improved, which facilitates the diversification of functions of the display panel 10.

[0242] Further, see Figure 9 and Figure 10 As shown, when the outer contours of the plurality of light-emitting units 121 in the pixel unit 12a collectively form a circular shape, the light-transmitting reserved area A is set between two adjacent pixel units 12a along the third direction M. This can fully utilize the space and improve the transmittance of the display panel 10.

[0243] Optionally, see Figure 9 and Figure 10As shown, the light-transmitting reserved area A is located between two pixel units 12 a adjacent to each other along the fourth direction N; the first direction X, the second direction Y, the third direction M and the fourth direction N intersect with each other.

[0244] In this way, the transmittance of the display panel 10 can be improved, which facilitates the diversification of functions of the display panel 10 .

[0245] Optionally, the light-transmitting reserved area A is provided with a light-transmitting hole (not shown).

[0246] In one embodiment, see Figure 2 and Figure 9 As shown, in the same pixel unit 12a, the first light emitting unit 121a is arranged around a portion of the periphery of the second light emitting unit 121b.

[0247] In this way, the distance between the first light emitting unit 121 a and the second light emitting unit 121 b can be reduced, so that the first light emitting unit 121 a and the second light emitting unit 121 b are arranged more compactly, thereby improving the display effect of the display panel 10 .

[0248] Optionally, see Figure 2 and Figure 9 As shown, in the same pixel unit 12a, the outer contour of the first light-emitting unit 121a includes a first side S11 and a second side S12 arranged close to the second light-emitting unit 121b; the outer contour of the second light-emitting unit 121b includes a third side S13 and a fourth side S14 arranged close to the first light-emitting unit 121a; the first side S11 and the third side S13 are adjacent to and parallel to each other; the second side S12 and the fourth side S14 are adjacent to and parallel to each other.

[0249] In this way, the first light emitting unit 121 a and the second light emitting unit 121 b can be arranged compactly, thereby improving the display effect of the display panel 10 .

[0250] Optionally, see Figure 2 and Figure 9 As shown, the first side S11 and the third side S13 are both parallel to the first direction X; the second side S12 and the fourth side S14 are both parallel to the second direction Y; and the first direction X and the second direction Y intersect.

[0251] In this way, the first side S11 and the third side S13 are straight sides parallel to the first direction X, the second side S12 and the fourth side S14 are straight sides parallel to the second direction Y, and the spacing between adjacent straight sides is small. In this way, the compactness of the arrangement of the first light-emitting unit 121a and the second light-emitting unit 121b can be further improved, thereby improving the display effect of the display panel 10.

[0252] Optionally, see Figure 2 and Figure 9As shown, the first side S11 is connected to the second side S12; the third side S13 is connected to the fourth side S14.

[0253] Optionally, see Figure 2 and Figure 9 As shown, the outer contour of the first light emitting unit 121a further includes a fifth side S15 and a sixth side S16 disposed away from the second light emitting unit 121b; the fifth side S15 is parallel to the first direction X; and the sixth side S16 is parallel to the second direction Y.

[0254] In this way, the outer contour of the first light-emitting unit 121a can have multiple straight edges. When the cathode of the vapor-deposited light-emitting unit 121 overlaps with the isolation structure 13, the outer contour of the first light-emitting unit 121a has straight edges parallel to the vapor deposition scanning direction and straight edges perpendicular to the vapor deposition scanning direction. This is beneficial to improving the overlapping reliability of the cathode of the light-emitting unit 121 and the isolation structure 13, making the display of the display panel 10 more uniform and improving the display quality of the display panel 10.

[0255] Optionally, see Figure 2 and Figure 9 As shown, the outer contour of the first light-emitting unit 121a also includes a seventh side S17 and an eighth side S18, the seventh side S17 connects the first side S11 and the fifth side S15; the seventh side S17 is parallel to the second direction Y; the eighth side S18 connects the second side S12 and the sixth side S16; the eighth side S18 is parallel to the first direction X.

[0256] In this way, the outer contour of the first light-emitting unit 121a can have more straight edges parallel to the evaporation scanning direction and straight edges perpendicular to the evaporation scanning direction. In this way, the overlap reliability of the cathode of the light-emitting unit 121 and the isolation structure 13 can be further improved, making the display of the display panel 10 more uniform and improving the display quality of the display panel 10.

[0257] Optionally, see Figure 2 and Figure 9 As shown, the outer contour of the second light emitting unit 121b also includes a ninth side S19 and a tenth side S20; the ninth side S19 is connected to the third side S13, and the ninth side S19 is parallel to the second direction Y; the tenth side S20 is connected to the fourth side S14; the tenth side S20 is parallel to the first direction X.

[0258] In this way, the outer contour of the second light-emitting unit 121b can have multiple straight edges. When the cathode of the vapor-deposited light-emitting unit 121 overlaps with the isolation structure 13, the outer contour of the second light-emitting unit 121b has straight edges parallel to the vapor deposition scanning direction and straight edges perpendicular to the vapor deposition scanning direction. This is beneficial to improving the overlapping reliability of the cathode of the light-emitting unit 121 and the isolation structure 13, making the display of the display panel 10 more uniform and improving the display quality of the display panel 10.

[0259] Optionally, see Figure 2 and Figure 9 As shown, the outer contour of the third light emitting unit 121 c includes an eleventh side S21 parallel to the first direction X and a twelfth side S22 parallel to the second direction Y.
