[0026] Figure 11 is a schematic diagram of the arrangement of light-emitting elements of a first display panel provided by an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the structure of a minimal repeating unit in Figure 3 yes Figure 2 A schematic structural diagram of a first repeating unit group, Figure 4 yes Figure 2 A schematic structural diagram of a second repeating unit group, Figure 5 is a schematic diagram of the arrangement of light-emitting elements of a second display panel provided by an embodiment of the present invention, Figure 6 yes Figure 5 Schematic diagram of the structure of a minimal repeating unit, reference Figures 1 to 6 As shown, an embodiment of the present invention provides a display panel 10, which includes a display area AA; the display area AA includes a minimum repeating unit 100 arranged in an array, and the minimum repeating unit 100 includes a first repeating unit group 110 and a second repeating unit group 120 arranged along a first direction X1; the first repeating unit group 110 and the second repeating unit group 120 both include a first sub-repeating unit 210 and a second sub-repeating unit 220 arranged along a second direction X2; the direction in which the first sub-repeating unit 210 points to the second sub-repeating unit 220 in the first repeating unit group 110 is opposite to the direction in which the first sub-repeating unit 210 points to the second sub-repeating unit 220 in the second repeating unit group 120;

[0027] The first sub-repeating unit 210 and the second sub-repeating unit 220 each include a first color light-emitting element 310, two second color light-emitting elements 320, and one third color light-emitting element 330; the direction in which the first color light-emitting element 310 in the first sub-repeating unit 210 points to the third color light-emitting element 330 is opposite to the direction in which the first color light-emitting element 310 points to the third color light-emitting element 330 in the second sub-repeating unit 220; the two second color light-emitting elements 320 in the first sub-repeating unit 210 and the second sub-repeating unit 220 are arranged along the second direction X2;

[0028] In which, the color of the light-emitting element in the first sub-repeating unit 210 located in the first repeating unit group 110 and close to the second sub-repeating unit 220 in the second repeating unit group 120 is the same as the color of the light-emitting element in the second sub-repeating unit 220 located in the second repeating unit group 120 and close to the first repeating unit group 110; the first direction X1 and the second direction X2 intersect and are perpendicular to the thickness direction of the display panel 10.

[0029] Among them, reference Figures 1 to 6As shown, the display panel 10 provided in an embodiment of the present invention includes a display area AA, which is used to display images. The display area AA includes minimal repeating units 100 arranged in rows and columns, and the minimal repeating units 100 include multiple light-emitting elements 300. The display panel 10 drives the light-emitting elements 300 to emit light and display, thereby realizing the display function of the display panel 10. The light-emitting elements 300 include first color light-emitting elements 310, second color light-emitting elements 320, and third color light-emitting elements 330. The display panel 10 drives the light-emitting elements 300 of different colors to emit light and display, thereby realizing the color display effect of the display panel 10. Furthermore, the minimal repeating unit 100 is the smallest unit in which the light-emitting elements 300 of different colors are repeatedly arranged in the row or column direction in the display area 100. It is understandable that the row direction can be the direction in which the scan lines (not specifically shown in the figure) in the display panel 10 extend, and the column direction can be the direction in which the data signal lines (not specifically shown in the figure) in the display panel 10 extend.

[0030] Specifically, refer to Figures 1 to 4 As shown, or refer to Figures 5 to 6 As shown, the minimum repeating unit 100 includes a first repeating unit group 110 and a second repeating unit group 120. In the minimum repeating unit 100, the first repeating unit group 110 and the second repeating unit group 120 are arranged along the first direction X1. Figure 2 Or refer to Figure 6 As shown, in the minimum repeating unit 100, the second repeating unit group 120 is arranged on one side of the first repeating unit group 110 along the first direction X1. In the minimum repeating unit 100, the plurality of light-emitting elements 300 are divided into the first repeating unit group 110 and the second repeating unit group 120. This facilitates dividing the arrayed minimum repeating unit 100 in the display area AA and further understanding the arrangement pattern of the light-emitting elements 300 in the display area AA.

[0031] Furthermore, the first repeating unit group 110 and the second repeating unit group 120 both include a first sub-repeating unit 210 and a second sub-repeating unit 220 arranged along the second direction X2. The first sub-repeating unit 210 and the second sub-repeating unit 220 can be understood as more detailed areas for dividing the plurality of light-emitting elements 300. By adjusting the different arrangements of the first sub-repeating unit 210 and the second sub-repeating unit 220 in the first repeating unit group 110 and the second repeating unit group 120, it is easy to understand the differentiated settings of the first repeating unit group 110 and the second repeating unit group 120, thereby reflecting the arrangement rules of the light-emitting elements 300 in the minimum repeating unit 100. Among them, the direction in which the first sub-repeating unit 210 points to the second sub-repeating unit 220 in the first repeating unit group 110 is opposite to the direction in which the first sub-repeating unit 210 points to the second sub-repeating unit 220 in the second repeating unit group 120. For example, with reference to Figures 2 to 4 Or refer to Figure 6 As shown, in the first repeating unit group 110, the direction in which the first sub-repeating unit 210 points to the second sub-repeating unit 220 is the second direction X2, and in the second repeating unit group 120, the direction in which the second sub-repeating unit 220 points to the first sub-repeating unit 210 is the second direction X2. Figure 3 and Figure 4 , which can also be understood as the first sub-repeating unit 210 and the second sub-repeating unit 220 being arranged in a mirror-symmetrical manner.

[0032] For further reference, Figures 1 to 6 As shown, the first sub-repeating unit 210 is composed of light-emitting elements 300 of different colors. The first sub-repeating unit 210 includes one first-color light-emitting element 310, two second-color light-emitting elements 320, and one third-color light-emitting element 330. Similarly, the second sub-repeating unit 220 also includes one first-color light-emitting element 310, two second-color light-emitting elements 320, and one third-color light-emitting element 330. Optionally, the first-color light-emitting element 310 can be understood as a red light-emitting element, the second-color light-emitting element 320 can be understood as a green light-emitting element, and the third-color light-emitting element 330 can be understood as a blue light-emitting element. The display panel 10 includes light-emitting elements 300 of different colors to achieve a color display effect of the display panel 10.

[0033] Furthermore, although the first sub-repeating unit 210 and the second sub-repeating unit 220 both include a plurality of light-emitting elements 300 of different colors, the arrangement of the light-emitting elements 300 is different. Figures 2 to 4 As shown, or refer to Figure 6As shown, the direction in which the first color light-emitting element 310 points to the third color light-emitting element 330 in the first sub-repeat unit 210 is opposite to the direction in which the first color light-emitting element 310 points to the third color light-emitting element 330 in the second sub-repeat unit 220. This can be understood as that the setting positions of the first color light-emitting element 310 and the third color light-emitting element 330 in the first sub-repeat unit 210 and the second sub-repeat unit 220 are swapped, and the difference between the first sub-repeat unit 210 and the second sub-repeat unit 220 is reflected by the first color light-emitting element 310 and the third color light-emitting element 330.

[0034] Furthermore, the color of the light-emitting element of the first sub-repeating unit 210 in the first repeating unit group 110 close to the second sub-repeating unit 220 in the second repeating unit group 120 is the same as the color of the light-emitting element of the second sub-repeating unit 220 in the second repeating unit group 120 close to the first sub-repeating unit 210 in the first repeating unit group 110. Figure 2 As shown, the light emitting element 300 in the first sub-repeating unit 210 in the first repeating unit group 110 close to the second sub-repeating unit 220 in the second repeating unit group 120 is Figure 2 The light emitting element 300A shown in FIG. 3 is a light emitting element 300A, wherein the light emitting element 300 is located in the second sub-repeating unit 220 in the second repeating unit group 120 and is close to the first sub-repeating unit 210 in the first repeating unit group 110. Figure 2 In the minimum repeating unit 100 provided in the embodiment of the present invention, the light emitting element 300A and the light emitting element 300B are light emitting elements of the same color. Similarly, the light emitting element 300 in the second sub-repeating unit 220 in the first repeating unit group 110, which is close to the first sub-repeating unit 210 in the second repeating unit group 120, is Figure 2 In the light emitting element 300C shown in FIG, the light emitting element 300 of the first sub-repeating unit 210 in the second repeating unit group 120 close to the second sub-repeating unit 220 of the first repeating unit group 110 is Figure 2 As shown in FIG. 3 , in the minimal repeating unit 100 provided in an embodiment of the present invention, light-emitting element 300C and light-emitting element 300D are light-emitting elements of the same color. By arranging light-emitting elements 300 of the same color adjacent to each other, during the manufacturing process of the display panel 10, the adjacent light-emitting elements 300 can be manufactured by co-evaporation. This improves the aperture ratio and ensures the display effect while reducing the manufacturing cost of the display panel 10 and extending the service life of the components of the display panel 10.

[0035] Furthermore, in the first sub-repeating unit 210 and the second sub-repeating unit 220, two second color light emitting elements 320 are arranged along the second direction X2. Figure 2and Figure 6 As shown, in the first repeating unit group 110, the first sub-repeating unit 210 and the second sub-repeating unit 220 are arranged along the second direction X2. Therefore, in the first repeating unit group 110, the second color light-emitting element 320 in the first sub-repeating unit 210 is adjacent to the second color light-emitting element 320 in the second sub-repeating unit 220. Similarly, in the second repeating unit group 120, the first sub-repeating unit 210 and the second sub-repeating unit 220 are also arranged along the second direction X2. Therefore, in the second repeating unit group 120, the second color light-emitting element 320 in the first sub-repeating unit 210 is adjacent to the second color light-emitting element 320 in the second sub-repeating unit 220. Furthermore, in the minimum repeating unit 100, the second color light-emitting elements 320 are also arranged adjacent to each other, further improving the aperture ratio while also reducing the manufacturing cost of the display panel 10.

[0036] In general, reference Figures 1 to 6 As shown, there are differences in the arrangement of the light-emitting elements 300 in the first sub-repeating unit 210 and the second sub-repeating unit 220. By adjusting the arrangement positions of the first sub-repeating unit 210 and the second sub-repeating unit 220, the difference in the arrangement of the light-emitting elements 300 in the first repeating unit group 110 and the second repeating unit group 120 can be seen. By further adjusting the arrangement positions of the first repeating unit group 110 and the second repeating unit group 120, the arrangement pattern of the light-emitting elements 300 in the minimum repeating unit 100 can be seen. In other words, the first sub-repeating unit 210, the second sub-repeating unit 220, the first repeating unit group 110 and the second repeating unit group 120 can be understood as being used to divide the light-emitting elements 300 into regions, thereby reflecting the arrangement pattern of the light-emitting elements 300 in the minimum repeating unit 300.

[0037] In the minimum repeating unit 100, there are multiple light emitting elements 300 of the same color arranged adjacent to each other. Figures 1 to 6As shown, there are first color light emitting elements 310 arranged adjacent to each other, there are second color light emitting elements 320 arranged adjacent to each other, and there are third color light emitting elements 330 arranged adjacent to each other. When the adjacent light emitting elements 300 have the same color, they can be prepared by a common evaporation method, which can avoid the situation where the aperture ratio is small due to evaporation deviation. Moreover, such an arrangement of the light emitting elements 300 is not easy to cause color mixing or color loss when evaporating light emitting elements 300 of different colors. For example, in the preparation process of the light emitting elements 300, an evaporation process is generally adopted. In the actual evaporation process, there will be a certain amount of evaporation deviation. However, in the arrangement of the light emitting elements 300 provided in the embodiment of the present invention, there are more light emitting elements 300 of the same color arranged adjacent to each other. On the one hand, the light emitting elements 300 of the same color can be prepared by a synchronous evaporation process, reducing the difficulty of the process preparation. On the other hand, even if there is an evaporation deviation, the two light emitting elements 300 of the same color can still retain a complete light emitting element 300, thereby reducing the risk of color loss caused by evaporation deviation and ensuring the display effect of the display panel 10. In general, the arrangement of the light-emitting elements 300 provided in the embodiment of the present invention can improve the aperture ratio to ensure the display effect, while also reducing the process manufacturing cost of the display panel 10 and extending the device service life of the display panel 10.

[0038] In summary, an embodiment of the present invention provides a display panel, which adjusts the setting positions of light-emitting elements of different colors in the minimum repeating unit to achieve adjacent settings of multiple light-emitting elements of the same color in the minimum repeating unit, thereby reducing the difficulty of preparing the display panel and ensuring the overall display effect of the display panel.

[0039] Continue to refer Figures 1 to 6 As shown, the wavelength of the emitted light of the first color light emitting element 310 is a1, the wavelength of the emitted light of the second color light emitting element 320 is a2, and the wavelength of the emitted light of the third color light emitting element 330 is a3; wherein, a1>a2>a3.

[0040] Specifically, the minimum repeating unit 100 includes a plurality of first color light emitting elements 310, a plurality of second color light emitting elements 320, and a plurality of third color light emitting elements 330, and the arrangement of the first color light emitting elements 310, the second color light emitting elements 320, and the third color light emitting elements 330 in the minimum repeating unit 100 can refer to Figures 1 to 6 Optionally, in order to ensure the overall display effect of the display panel 10 , the arrangement of the first color light emitting element 310 , the second color light emitting element 320 and the third color light emitting element 330 may be adjusted according to the wavelength of the emitted light corresponding to the light emitting element 300 .

[0041] The wavelength of light emitted by the first color light-emitting element 310 is greater than the wavelength of light emitted by the second color light-emitting element 320, and the wavelength of light emitted by the second color light-emitting element 320 is greater than the wavelength of light emitted by the third color light-emitting element 330. The arrangement of the light-emitting elements 300 in the minimal repeating unit 100 is adjusted based on the difference in the wavelengths of the emitted light. Specifically, the wavelength of light emitted by the first color light-emitting element 310 is a1, the wavelength of light emitted by the second color light-emitting element 320 is a2, and the wavelength of light emitted by the third color light-emitting element 330 is a3, satisfying the following conditions: a1>a2>a3. Alternatively, the first color light-emitting element 310 may be a red light-emitting element with a wavelength of 700 nanometers, the second color light-emitting element 320 may be a green light-emitting element with a wavelength of 546 nanometers, and the third color light-emitting element 330 may be a blue light-emitting element with a wavelength of 436 nanometers. The specific values ​​of a1, a2, and a3 can be adjusted adaptively based on different display panels 10 and are not specifically limited in this embodiment of the present invention.

[0042] Continue to refer Figures 1 to 6 As shown, the first sub-repeat unit 210 and the second sub-repeat unit 220 each further include a fourth color light-emitting element 340; in the first sub-repeat unit 210, the fourth color light-emitting element 340 is located at the center of the first sub-repeat unit 210, and the first color light-emitting element 310, the second color light-emitting element 320 and the third color light-emitting element 330 surround the fourth color light-emitting element 340; in the second sub-repeat unit 220, the fourth color light-emitting element 340 is located at the center of the first sub-repeat unit 220, and the first color light-emitting element 310, the second color light-emitting element 320 and the third color light-emitting element 330 surround the fourth color light-emitting element 340.

[0043] Specifically, refer to Figures 1 to 6 As shown, the first sub-repeating unit 210 and the second sub-repeating unit 220 also include a fourth color light-emitting element 340, that is, the minimum repeating unit 100 includes a first color light-emitting element 310, a second color light-emitting element 320, a third color light-emitting element 330 and a fourth color light-emitting element 340. By adding the fourth color light-emitting element 340, the color diversity of the light-emitting element 300 in the minimum repeating unit 100 is reflected, and the combination of multiple light-emitting elements 300 of different colors further ensures the display effect of the display panel 10.

[0044] refer to Figures 1 to 6As shown, in the first sub-repeating unit 210, the fourth color light-emitting element 340 is located at the center of the first sub-repeating unit 210, and the first color light-emitting element 310, the second color light-emitting element 320, and the third color light-emitting element 330 surround the fourth color light-emitting element 340. The second sub-repeating unit 210 can be understood as the first color light-emitting element 310 and the third color light-emitting element 320 in the first sub-repeating unit 210 are swapped. Therefore, in the second sub-repeating unit 220, the fourth color light-emitting element 340 is also located at the center of the first sub-repeating unit 210, and the first color light-emitting element 310, the second color light-emitting element 320, and the third color light-emitting element 330 are arranged around the fourth color light-emitting element 340.

[0045] Continue to refer Figures 1 to 6 As shown, the wavelength of the emitted light of the first color light emitting element 310 is a1, the wavelength of the emitted light of the second color light emitting element 320 is a2, the wavelength of the emitted light of the third color light emitting element 330 is a3, and the wavelength of the emitted light of the fourth color light emitting element 340 is a4; wherein, a1>a4>a2>a3.

[0046] The wavelength a1 of the emitted light from the first color light-emitting element 310 is greater than the wavelength a2 of the emitted light from the second color light-emitting element 320, and the wavelength a2 of the emitted light from the second color light-emitting element 320 is greater than the wavelength a3 of the emitted light from the third color light-emitting element 330, i.e., a1>a2>a3. Based on the actual wavelengths of light, the first color light-emitting element 310 can be considered a red light-emitting element, the second color light-emitting element 320 can be considered a green light-emitting element, and the third color light-emitting element 330 can be considered a blue light-emitting element. Furthermore, the wavelength of the emitted light from the fourth color light-emitting element 340 is less than that of the first color light-emitting element 310, and the wavelength of the emitted light from the fourth color light-emitting element 340 is greater than that of the second color light-emitting element 320. Therefore, the fourth color light-emitting element 340 can be a yellow light-emitting element. The display panel 10 provided in this embodiment of the present invention, in addition to the red, green, and blue light-emitting elements 300 arranged in the display area AA, can increase the overall display brightness of the display panel 10, thereby improving the overall display quality of the display panel 10.

[0047] Figure 7 yes Figure 1 An enlarged schematic diagram of area A in the middle, Figure 8 yes Figure 5 An enlarged schematic diagram of area B in the middle, refer to Figure 7 and Figure 8As shown, two adjacent minimum repeating units 100 are arranged along the third direction X3; in the first sub-repeat unit 210 and the second sub-repeat unit 220, along the second direction X2, the two second color light-emitting elements 320 are located on both sides of the fourth color light-emitting element 340, and along the third direction X3, the center of the first color light-emitting element 310 and the center of the third color light-emitting element 330 are located on both sides of the center of the fourth color light-emitting element 340; the third direction X3 intersects with the second direction X1 and is perpendicular to the thickness direction of the display panel 10.

[0048] Specifically, the minimum repeating unit 100 is arranged along the third direction X3, and the third direction X3 can be understood as the row direction of the display panel 10, that is, the direction in which the scan lines (not specifically shown in the figure) in the display panel 10 extend. Figure 7 and Figure 8 As shown, Figure 7 and Figure 8 The two first sub-repeating units 210 (first sub-repeating unit 210a and first sub-repeating unit 210b) shown in the figure can be understood as the first sub-repeating units 210 corresponding to the same position in the two minimum repeating units 100; and the arrangement relationship between the first sub-repeating unit 210a and the first sub-repeating unit 210b can be understood as the arrangement relationship between the two minimum repeating units 100, that is, the two adjacent minimum repeating units 100 are arranged along the third direction X3. Similarly, Figure 7 and Figure 8 The two second sub-repeating units 220 (the second sub-repeating unit 220a and the second sub-repeating unit 220b) are shown, wherein the second sub-repeating unit 220a and the second sub-repeating unit 220b can be understood as the second sub-repeating units 220 corresponding to the same position in the two minimum repeating units 100; and the arrangement relationship between the second sub-repeating unit 220a and the second sub-repeating unit 220b can be understood as the arrangement relationship between the two minimum repeating units 100, that is, the two adjacent minimum repeating units 100 are arranged along the third direction X3.

[0049] Furthermore, the first sub-repeating unit 210 and the second sub-repeating unit 220 include a first color light-emitting element 310, a second color light-emitting element 320, a third color light-emitting element 330, and a fourth color light-emitting element 340. The first color light-emitting element 310, the second color light-emitting element 320, and the third color light-emitting element 330 are arranged around the fourth color light-emitting element 340, wherein along the second direction X2, the two second color light-emitting elements 320 are located on both sides of the fourth color light-emitting element 340, and along the third direction X3, the first color light-emitting element 310 and the third color light-emitting element 330 are located on both sides of the fourth color light-emitting element 340. Furthermore, for the first color light-emitting element 310, the third color light-emitting element 330 and the fourth color light-emitting element 340, along the third direction X3, the center of the first color light-emitting element 310 and the center of the third color light-emitting element 330 are located on both sides of the center of the fourth color light-emitting element 340. In this way, the first color light-emitting element 310, the second color light-emitting element 320 and the third color light-emitting element 330 are regularly arranged around the fourth color light-emitting element 340. The relatively regular arrangement of the light-emitting elements 300 facilitates the evaporation of the light-emitting elements 300, reduces the difficulty of the process preparation of the display panel 10, and can ensure the overall display effect of the display panel 10.

[0050] Continue to refer Figures 1 to 8 As shown, in the first sub-repeating unit 210 and the second sub-repeating unit 220, the area of ​​a first color light-emitting element 310 is s1, the area of ​​two second color light-emitting elements 320 is s2, the area of ​​a third color light-emitting element 330 is s3, and the area of ​​a fourth color light-emitting element 340 is s4; wherein, s1=s3>s4, s2>s4.

[0051] The first sub-repeating unit 210 and the second sub-repeating unit 220 each include a plurality of light-emitting elements 300 of different colors, which are used to achieve a color display effect on the display panel 10. In the first sub-repeating unit 210 and the second sub-repeating unit 220, the first color light-emitting elements 310 and the third color light-emitting elements 330 are located on opposite sides of the fourth color light-emitting elements 340. To ensure a regular arrangement of the light-emitting elements 300 in the display panel 10, the area of ​​the first color light-emitting elements 310 and the area of ​​the third color light-emitting elements 330 are set to be the same. This ensures the regularity of the first sub-repeating unit 210 and the second sub-repeating unit 220, and also reduces the difficulty of the process for preparing the light-emitting elements 300 of different colors, thereby reducing the production cost of the display panel 10.

[0052] Furthermore, the first color light-emitting element 310 may be a red light-emitting element, the third color light-emitting element 330 may be a blue light-emitting element, the second color light-emitting element 320 may be a green light-emitting element, and the fourth color light-emitting element 340 may be a yellow light-emitting element. In the first sub-repeating unit 210 and the second sub-repeating unit 220, the two second color light-emitting elements 320 are located on opposite sides of the fourth color light-emitting element 340. The yellow light-emitting element 340 is used to increase the overall display brightness of the display panel 10 and reduce the power consumption of the display panel 10. Therefore, the area of ​​the fourth color light-emitting element 340 can be set to be smaller than the areas of the light-emitting elements 300 of other colors. By adjusting the areas of the light-emitting elements 300 of different colors in the minimum repeating unit 100, while ensuring the overall display effect of the display panel 10, the difficulty and cost of manufacturing the display panel 10 can be reduced.

[0053] Continue to refer Figures 1 to 8 As shown, in the first sub-repeating unit 210 and the second sub-repeating unit 220 , the shape of the first color light emitting element 310 is the same as the shape of the third color light emitting element 330 .

[0054] Among them, the area of ​​the first color light-emitting element 310 in the first sub-repeating unit 210 and the second sub-repeating unit 220 is s1, and the area of ​​the third color light-emitting element 330 is s3, satisfying s1=s3. Furthermore, the shape of the first color light-emitting element 310 can be adjusted to be the same as the shape of the third color light-emitting element 330. On the one hand, it can better ensure that the shapes of the first sub-repeating unit 210 and the second sub-repeating unit 220 are regular. On the other hand, when performing the preparation process of the light-emitting element 300, it can reduce the difficulty of the process preparation and reduce the preparation cost of the display panel 10.

[0055] Figure 9 is a schematic diagram of the arrangement of light-emitting elements of a second display panel provided by an embodiment of the present invention, Figure 10 yes Figure 9 Schematic diagram of the structure of a minimal repeating unit, reference Figure 9 and Figure 10 As shown, in the first sub-repeating unit 210 and the second sub-repeating unit 220, the area of ​​a first color light-emitting element 310 is s1, the area of ​​two second color light-emitting elements 320 is s2, the area of ​​a third color light-emitting element 330 is s3, and the area of ​​a fourth color light-emitting element 340 is s4; wherein, s3>s2>s1>s4.

[0056] Among them, combined Figure 9 and Figure 10As shown, the first sub-repeating unit 210 and the second sub-repeating unit 220 both include a plurality of light emitting elements 300 of different colors, for achieving a color display effect of the display panel 10. Figure 7 、 Figure 8 and Figure 10 As shown, in the first sub-repeating unit 210 and the second sub-repeating unit 220, along the third direction X3, the center of the first color light emitting element 310 and the center of the third color light emitting element 330 are located on both sides of the center of the fourth color light emitting element 340. Figure 7 and Figure 8 The minimum repeating unit 100 is set with the area of ​​the first color light emitting element 310 and the area of ​​the third color light emitting element 330 being the same as that of the fourth color light emitting element 340; Figure 10 As shown, the area of ​​the first color light emitting element 310 located on both sides of the fourth color light emitting element 340 is smaller than the area of ​​the third color light emitting element 330, and the minimum repeating unit 100 is arranged. Figure 7 and Figure 10 The first sub-repeating unit 210 and the second sub-repeating unit 220 are arranged as regular hexagons. Figure 10 The center of the first color light emitting element 310, the center of the third color light emitting element 330 and the center of the fourth color light emitting element 340 are relative to Figure 7 As shown, the offset reduces the area of ​​the first color light-emitting element 310 and increases the area of ​​the third color light-emitting element 330, thereby achieving differentiated arrangement of the areas of the first color light-emitting element 310 and the third color light-emitting element 330. The area of ​​the first color light-emitting element 310 is s1, and the area of ​​the third color light-emitting element 330 is s3, satisfying s1<s3.

[0057] Among them, reference Figure 10 As shown, in the first sub-repeating unit 210 and the second sub-repeating unit 220, two second-color light-emitting elements 320 are located on opposite sides of the fourth-color light-emitting element 340, and the area of ​​the two second-color light-emitting elements 320 is s2. In order to better match the life attenuation degree of the display panel 10, s3>s2>s1 is adjusted. Furthermore, the fourth-color light-emitting element 340 can be a yellow light-emitting element. The additional yellow light-emitting element 340 is used to improve the overall display brightness of the display panel 10 and reduce the power consumption of the display panel 10. Therefore, the area of ​​the fourth-color light-emitting element 340 can be set to be smaller than the area of ​​the light-emitting elements 300 of other colors. By adjusting the area of ​​the light-emitting elements 300 of different colors in the minimum repeating unit 100, while ensuring the overall display effect of the display panel 10, the difficulty of the process preparation of the display panel 10 can be reduced, and the process preparation cost of the display panel 10 can be reduced.

[0058] With reference to Figures 1 to 4 , Figure 7 , Figure 9 and Figure 10 , the first sub-repeating unit 210 comprises a hexagonal first sub-repeating unit; the second sub-repeating unit 220 comprises a hexagonal second sub-repeating unit; the first direction X1 and the third direction X3 intersect.

[0059] As shown in reference to Figures 1 to 4 , Figure 7 , Figure 9 and Figure 10 , the first sub-repeating unit 210 comprises a hexagonal first sub-repeating unit, and the second sub-repeating unit 220 comprises a hexagonal second sub-repeating unit, i.e. the first sub-repeating unit 210 and the second sub-repeating unit used to compose the minimum repeating unit 100 are hexagonal, and the first sub-repeating unit 210 of the regular hexagon and the second sub-repeating unit 220 of the regular hexagon are realized by adjusting the area and shape of the light emitting elements 300 of different colors, which on the one hand can better reflect the array arrangement mode of the minimum repeating unit 100, and on the other hand can ensure the display uniformity of the display panel 10 and improve the overall display effect of the display panel 10 by adjusting the light emitting elements 300 of different colors.

[0060] Further, as shown in reference to Figures 1 to 4 , Figure 7 , Figure 9 and Figure 10 , when the first sub-repeating unit 210 and the second sub-repeating unit 220 are regular hexagons, there is an included angle between the first direction X1 and the third direction X3.

For example, a regular quadrilateral is shown in the figure. The regular quadrilateral first sub-repeating unit 210 and the regular quadrilateral second sub-repeating unit 220 are realized by adjusting the area and shape of light-emitting elements 300 of different colors. On the one hand, it can better reflect the array arrangement of the minimum repeating unit 100. On the other hand, by adjusting the light-emitting elements 300 of different colors, the display uniformity of the display panel 10 can be ensured, and the overall display effect of the display panel 10 can be improved.

[0063] For further reference, Figure 5 、 Figure 6 and Figure 8 As shown, when the first sub-repeating unit 210 and the second sub-repeating unit 220 are regular quadrilaterals, the first direction X1 and the third direction X3 are the same direction, which can be understood as the row direction in the figure. The first direction X1 is the arrangement direction of the first sub-repeating unit 210 and the second sub-repeating unit 220, and the third direction X3 is the arrangement direction of the first color light-emitting elements 310 and the third color light-emitting elements 330 in the first sub-repeating unit 210 or the second sub-repeating unit 220.

[0064] Continue to refer Figure 7 and Figure 8 As shown, the minimum spacing between the first color light-emitting element 310 in the first sub-repeat unit 210 and the first color light-emitting element 310 in the second sub-repeat unit 220 is b1; the minimum spacing between the second color light-emitting element 320 in the first sub-repeat unit 210 and the second color light-emitting element 320 in the second sub-repeat unit 220 is b2; the minimum spacing between the third color light-emitting element 330 in the first sub-repeat unit 210 and the third color light-emitting element 330 in the second sub-repeat unit 220 is b3; wherein, |b1-b2| / b2≤20%, |b2-b3| / b3≤20%.

[0065] Specifically, refer to Figure 7 and Figure 8As shown, the minimum spacing between the first color light-emitting elements 310 in the first sub-repeating unit 210 and the first color light-emitting elements 310 in the second sub-repeating unit 220 is b1, or it can be understood that the minimum spacing between the first color light-emitting elements 310 in the minimum repeating unit 100 is b1, or it can be understood that the distance between two adjacent first color light-emitting elements 310 in the minimum repeating unit 100 is b1. Similarly, the minimum spacing between the second color light-emitting elements 320 in the first sub-repeating unit 210 and the second color light-emitting elements 320 in the second sub-repeating unit 220 is b2, or it can be understood that the minimum spacing between the second color light-emitting elements 320 in the minimum repeating unit 100 is b2, or it can be understood that the distance between two adjacent second color light-emitting elements 320 in the minimum repeating unit 100 is b2. Similarly, the minimum spacing between the third color light-emitting elements 330 in the first sub-repeat unit 210 and the third color light-emitting elements 330 in the second sub-repeat unit 220 is b3, or it can be understood that the minimum spacing between the third color light-emitting elements 330 in the minimum repeat unit 100 is b3, or it can be understood that in the minimum repeat unit 100, the distance between two adjacent third color light-emitting elements 330 is b3.

[0066] Among them, |b1-b2| / b2≤20%, |b2-b3| / b3≤20%, which can be understood as b1, b2 and b3 are the same or similar in size, and can be understood as in the display panel 10, the gap value between the light-emitting element 300 in the first sub-repeating unit 210 and the light-emitting element 300 in the adjacent second sub-repeating unit 220 is similar, thereby reflecting that the arrangement of the light-emitting element 300 is regular, thereby ensuring that the overall display effect of the display panel 10 is better, and at the same time, the regularly arranged light-emitting elements 300 are beneficial to reducing the difficulty of the process preparation of the display panel 10 and reducing the preparation cost of the display panel 10.

[0067] Continue to refer Figure 7 and Figure 8 As shown, b1=b2=b3.

In order to further ensure the regularity of the display panel 10, b1=b2=b3 is adjusted.

[0069] Optionally, for b1, b2 and b3, which are the gaps between the same light-emitting elements 300 when they are arranged adjacent to each other, b1, b2 and b3 can be further adjusted to be close to zero, that is, two adjacent light-emitting elements 300 of the same color share an adjacent edge. In this way, there is no reduction between the light-emitting elements 300, which can provide an aperture ratio of the display panel 10, further improve the overall display effect of the display panel 10, and reduce the difficulty of vapor deposition during the preparation of the light-emitting elements 300.
