Technical Field

[0001] This application relates to the field of display panel technology, and more particularly to a display panel and a display device. Background Technology

[0002] With the development of display technology, various display technologies have emerged, and various display devices have been developed, including liquid crystal display panels, organic light-emitting display panels, plasma display panels, and electrophoretic display panels.

[0003] Based on this, users are becoming increasingly aware of the importance of protecting their personal privacy when using display devices, and how to achieve privacy protection for display devices has become a research hotspot. Summary of the Invention

[0004] This application provides a display panel and a display device to improve the privacy protection effect of the display panel from a wide viewing angle.

[0005] In a first aspect, embodiments of this application provide a display panel, including:

[0006] A substrate and multiple light-emitting elements located on one side of the substrate;

[0007] The plurality of light-emitting elements include a first light-emitting element and a second light-emitting element, the second light-emitting element including a first light-emitting portion and a second light-emitting portion, the second light-emitting portion surrounding at least a portion of the first light-emitting portion;

[0008] The system includes a light-shielding structure and a pixel definition layer. The light-shielding structure is located on the side of the light-emitting element away from the substrate. The light-shielding structure includes a first opening, a second opening, and a first light-shielding portion. Along a direction perpendicular to the plane of the substrate, the first opening at least partially overlaps with the first light-emitting element, the second opening at least partially overlaps with the first light-emitting portion, and the first light-shielding portion at least partially overlaps with the second light-emitting portion. The pixel definition layer includes a first pixel opening and a second pixel opening. The second pixel opening includes a first pixel opening portion and a second pixel opening portion. The second pixel opening portion surrounds at least a portion of the first pixel opening portion. At least a portion of the first light-emitting element is located within the first pixel opening. At least a portion of the first light-emitting portion is located within the first pixel opening portion. Along a direction parallel to the plane of the substrate, the minimum distance between the edge of the first opening and the edge of the first pixel opening is d1, and the minimum distance between the edge of the second opening and the edge of the first pixel opening portion is d2, where d1 > d2.

[0009] The display panel includes a sharing mode and a privacy mode.

[0010] In the shared mode, the first light-emitting element, the first light-emitting portion, and the second light-emitting portion all emit light;

[0011] In the privacy mode, both the first light-emitting element and the first light-emitting portion emit light, while the second light-emitting portion does not emit light.

[0012] Secondly, embodiments of this application provide a display panel, including:

[0013] A substrate and multiple light-emitting elements located on one side of the substrate;

[0014] The plurality of light-emitting elements include a first light-emitting element and a second light-emitting element, the second light-emitting element including a first light-emitting portion and a second light-emitting portion, the second light-emitting portion surrounding at least a portion of the first light-emitting portion;

[0015] The maximum light emission angle of the first light-emitting element is greater than the maximum light emission angle of the first light-emitting portion, and the minimum light emission angle of the second light-emitting portion is greater than the minimum light emission angle of both the first light-emitting element and the first light-emitting portion.

[0016] The display panel includes a sharing mode and a privacy mode.

[0017] In the shared mode, the first light-emitting element, the first light-emitting portion, and the second light-emitting portion all emit light;

[0018] In the privacy mode, both the first light-emitting element and the first light-emitting portion emit light, while the second light-emitting portion does not emit light.

[0019] Thirdly, embodiments of this application provide a display device including the display panel described in the first and second aspects above.

[0020] In summary, the display panel provided in this application includes a light-emitting element, a light-shielding structure, and a pixel definition layer. The light-emitting element includes a first light-emitting element and a second light-emitting element, the second light-emitting element further including a first light-emitting portion. The light-shielding structure includes a first opening and a second opening. The pixel definition layer includes a first pixel opening and a first pixel opening portion. By reasonably setting the positional relationship between the first opening and the first pixel opening, and the positional relationship between the second opening and the first pixel opening portion, the maximum light emission angle of the first light-emitting element is greater than the maximum light emission angle of the first light-emitting portion. Furthermore, the second light-emitting element also includes a second light-emitting portion, the second light-emitting portion surrounding at least a portion of the first light-emitting portion; the light-shielding structure also includes a first light-shielding portion, the first light-shielding portion and the second light-emitting portion at least partially overlap, so that the small-angle light emitted by the second light-emitting portion is blocked by the first light-shielding portion and cannot be emitted, that is, the minimum light emission angle of the second light-emitting portion is larger, thus the second light-emitting portion can be used to compensate for the large-angle light emission of the first light-emitting portion. In shared mode, the first light-emitting element, the first light-emitting section, and the second light-emitting section all emit light, achieving normal display at a wide viewing angle. In privacy mode, the second light-emitting section does not emit light, and only the first light-emitting element and the first light-emitting section emit light, thus the light from the second light-emitting element is not visible at a wide viewing angle. At a wide viewing angle, at least some light-emitting element groups will exhibit color skipping due to the missing light-emitting section, causing the displayed information to be blurred or disordered at a wide viewing angle, achieving a privacy display effect at a wide viewing angle. In addition, it can also reduce the power consumption of the display panel. Attached Figure Description

Figure 3 yes Figure 1 The diagram shown is a partial structural schematic of the display panel. Figure 4 yes Figure 1 The diagram shows another partial structure of the display panel. Figure 5 yes Figure 1 The diagram shows another partial structure of the display panel, combined with... Figures 1 to 5 As shown, the display panel provided in this application embodiment includes a substrate 1 and a plurality of light-emitting elements 2 located on one side of the substrate; the plurality of light-emitting elements 2 include a first light-emitting element 21 and a second light-emitting element 22, the second light-emitting element 22 includes a first light-emitting portion 22a and a second light-emitting portion 22b, the second light-emitting portion 22b surrounding at least a portion of the first light-emitting portion 22a; a light-shielding structure 3 and a pixel definition layer 4, the light-shielding structure 3 being located on the side of the light-emitting element 2 away from the substrate 1; the light-shielding structure 3 includes a first opening 31, a second opening 32 and a first light-shielding portion 33, along a direction perpendicular to the plane of the substrate 1 (the Y direction shown in the figure), the first opening 31 at least partially overlaps with the first light-emitting element 21, the second opening 32 at least partially overlaps with the first light-emitting portion 22a, and the first light-shielding portion 33 at least partially overlaps with the second light-emitting portion 22b; the pixel definition layer 4 includes a first pixel opening 41 and a second pixel opening 42, the second pixel opening 41 and the second pixel opening 42 are shown in the figure. The opening 42 includes a first pixel opening portion 42a and a second pixel opening portion 42b, with the second pixel opening portion 42b surrounding at least a portion of the first pixel opening portion 42a; at least a portion of the first light-emitting element 21 is located within the first pixel opening 41; at least a portion of the first light-emitting portion 22a is located within the first pixel opening portion 42a; along a direction parallel to the plane of the substrate 1 (as shown in X1), the minimum distance between the edge of the first opening 31 and the edge of the first pixel opening 41 is d1, and the minimum distance between the edge of the second opening 32 and the edge of the first pixel opening portion 42a is d2, where d1 > d2; the display mode of the display panel includes a sharing mode and a privacy mode; in the sharing mode, the first light-emitting element 21, the first light-emitting portion 22a, and the second light-emitting portion 22b all emit light; in the privacy mode, the first light-emitting element 21 and the first light-emitting portion 22a both emit light, while the second light-emitting portion 22b does not emit light.

[0060] Combination Figure 1 and Figure 2As shown, the display panel includes a substrate 1 and a plurality of light-emitting elements 2 located on one side of the substrate 1. The light-emitting elements 2 may include light-emitting elements of different colors, such as at least one of red, green, blue, or white light-emitting elements. Furthermore, the light-emitting elements 2 may be one of organic light-emitting diodes (OLEDs), micro-OLEDs, or micro-LEDs. Taking an OLED as an example, the light-emitting element 2 may include a first electrode, a second electrode, and an organic compound layer located between the first and second electrodes. The organic compound layer may include a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, an electron transport layer, a hole blocking layer, and an electron injection layer, but is not limited thereto. Alternatively, the organic compound layer may also include a charge-generating layer, such as a P-type charge-generating layer and an N-type charge-generating layer. When a voltage is applied to the first and second electrodes of the OLED, holes passing through the hole transport layer and electrons passing through the electron transport layer move to the light-emitting layer to form excitons, causing visible light to be emitted from the light-emitting layer.

[0061] Further reference Figure 2 As shown, the display panel also includes a pixel definition layer 4, which has multiple pixel openings that define the light-emitting area of ​​the light-emitting element. Specifically, the light-emitting element 2 includes a first light-emitting element 21 and a second light-emitting element 22. The second light-emitting element 22 includes a first light-emitting portion 22a and a second light-emitting element 22b, with the second light-emitting element 22b surrounding at least a portion of the first light-emitting portion 22a. Correspondingly, the pixel definition layer 4 includes a first pixel opening 41 and a second pixel opening 42, with the second pixel opening 42 including a first pixel opening portion 42a and a second pixel opening portion 42b, with the second pixel opening portion 42b surrounding at least a portion of the first pixel opening portion 42a. At least a portion of the first light-emitting element 21 is located within the first pixel opening 41, meaning at least a portion of the light-emitting film layer of the first light-emitting element 21 is located within the first pixel opening 41, and the first pixel opening 41 defines at least a portion of the light-emitting area of ​​the first light-emitting element 21. At least a portion of the first light-emitting portion 22a is located within the first pixel opening portion 42a, meaning at least a portion of the light-emitting film layer of the first light-emitting portion 22a is located within the first pixel opening portion 42a, and the first pixel opening portion 42a defines at least a portion of the light-emitting area of ​​the first light-emitting portion 22a. At least a portion of the second light-emitting portion 22b is located within the second pixel opening portion 42b, meaning at least a portion of the light-emitting film layer of the second light-emitting portion 22b is located within the second pixel opening portion 42b, and the second pixel opening portion 42b defines at least a portion of the light-emitting area of ​​the second light-emitting portion 22b. By setting the pixel definition layer 4 and the pixel opening, and defining at least a portion of the light-emitting film layer of the light-emitting element through the pixel opening, crosstalk between different light-emitting elements can be reduced, and the light emission contrast between different light-emitting elements can be improved.

[0062] Further reference Figure 2 As shown, the display panel also includes a light-shielding structure 3 located on the light-emitting side of the light-emitting element 2. The light-shielding structure 3 is used to adjust the light emission angle of the light-emitting element 2. Specifically, the light-shielding structure 3 includes a first opening 31, a second opening 32, and a first light-shielding portion 33. Along the direction perpendicular to the plane of the substrate 1, the first opening 31 at least partially overlaps with the first light-emitting element 21, so that at least part of the light generated by the first light-emitting element 21 can be emitted from the first opening 31; the second opening 32 at least partially overlaps with the first light-emitting portion 22a, so that at least part of the light generated by the first light-emitting portion 22a can be emitted from the second opening 32; the first light-shielding portion 33 at least partially overlaps with the second light-emitting portion 22b, so that the positive angle light, or small angle light, generated by the second light-emitting portion 22b is at least partially blocked by the first light-shielding portion 33 and cannot be emitted, while the large angle light generated by the second light-emitting portion 22b can at least partially be emitted from the second opening 32. It is understood that the viewing angle in the embodiments of this application can be understood as the acute angle formed between the propagation direction of the light emitted by the light-emitting element and the thickness direction of the display panel. A narrow viewing angle, or small viewing angle, can be understood as a small acute angle formed between the direction of the light emitted by the light-emitting element and the thickness direction of the display panel, such as 0°, 5°, or 10°, or an acute angle less than 30°; a large viewing angle can be understood as a large angle between the direction of the light emitted by the light-emitting element and the thickness direction of the display panel, such as 50°, 60°, or 70°, or an acute angle greater than or equal to 45°. The concepts of narrow and large viewing angles in the embodiments of this application are relative, and the embodiments of this application do not numerically limit the size of the viewing angle corresponding to a narrow or large viewing angle.

[0063] Further reference Figure 2As shown, along a direction perpendicular to the plane of substrate 1, the first opening 31 covers the first pixel opening 41, and the second opening 32 covers the first pixel opening portion 42a. This ensures that more light emitted from the first light-emitting element 21 can exit from the first opening 31, and more light emitted from the first light-emitting portion 22a can exit from the second opening 32. Furthermore, along a direction parallel to the plane of substrate 1 (as shown in the X1 direction), the minimum distance d1 between the edge of the first opening 31 and the edge of the first pixel opening 41 and the minimum distance d2 between the edge of the second opening 32 and the edge of the first pixel opening portion 42a satisfy d1 > d2. In other words, the distance between the edge of the first opening 31 and the edge of the first pixel opening 41 is relatively large, while the distance between the edge of the second opening 32 and the edge of the first pixel opening portion 42a is relatively small. Thus, light rays with a larger viewing angle emitted from the first light-emitting element 21 can exit through the first opening 31 without being blocked by the light-shielding area outside the first opening 31, while light rays with a larger viewing angle emitted from the first light-emitting portion 22a will be blocked by the light-shielding area outside the second opening 32 and cannot exit through the second opening 32. That is, after the light-shielding structure 3, the maximum light emission angle of the first light-emitting element 21 is greater than the maximum light emission angle of the first light-emitting portion 22a. Furthermore, the first light-shielding portion 33 and the second light-emitting portion 22b at least partially overlap. Thus, the positive viewing angle light rays generated by the second light-emitting portion 22b are at least partially blocked by the first light-shielding portion 33 and cannot exit, while the large viewing angle light rays generated by the second light-emitting portion 22b can at least partially be emitted from the second opening 32. Furthermore, the second light-emitting portion 22b surrounds the first light-emitting portion 22a. This reasonable arrangement of the light-emitting timing of the first light-emitting portion 22a and the second light-emitting portion 22b ensures that the second light-emitting element 22 can emit light from both narrow and wide viewing angles. It should be noted that this embodiment does not limit the specific values ​​of d1 and d2. The values ​​of d1 and d2 can be reasonably set according to the panel size and display resolution, for example, 0 < d2 < 2μm, d1 > 2μm.

[0064] Specifically, the display panel has two display modes: a sharing mode and a privacy mode. In sharing mode, the first light-emitting element 21, the first light-emitting portion 22a, and the second light-emitting portion 22b all emit light. Thus, the light emitted by the first light-emitting element 21 is visible from both the direct viewing angle and the wide viewing angle, the light emitted by the first light-emitting portion 22a is visible from the direct viewing angle, and the light emitted by the second light-emitting portion 22b is visible from the wide viewing angle. In other words, the light emitted by both the first light-emitting element 21 and the second light-emitting element 22 is visible from both the direct viewing angle and the wide viewing angle, achieving normal display at different viewing angles. In privacy mode, both the first light-emitting element 21 and the first light-emitting portion 22a emit light, while the second light-emitting portion 22b does not emit light. Thus, the light emitted by the first light-emitting element 21 is visible from both the direct viewing angle and the wide viewing angle, and the light emitted by the first light-emitting portion 22a is visible from the direct viewing angle, ensuring that the display panel has normal display content and brightness from the direct viewing angle, achieving normal display. The light emitted from the second light-emitting portion 22b is invisible at wide viewing angles. This means that the light emitted from the second light-emitting element 22 is partially missing at wide viewing angles, causing color skipping due to this partial light loss. This results in blurred or disordered information displayed at wide viewing angles, thus achieving information confidentiality. In essence, privacy protection prevents information from being observed at wide viewing angles, preventing it from being seen or spied upon, thereby achieving visibility at narrow viewing angles but not at wide viewing angles.

[0065] Furthermore, the display panel includes multiple light-emitting element groups 20, each including at least one first light-emitting element 21 and at least one second light-emitting element 22. In shared mode, the light emitted by the first light-emitting element 21 and the second light-emitting element 22 within the same light-emitting element group 20 is visible at both normal and wide viewing angles, achieving normal display in shared mode. In privacy mode, at least one non-emitting second light-emitting portion 22b exists within the same light-emitting element group 20. This non-emitting second light-emitting portion 22b ensures that the light-emitting element 20 and other light-emitting element groups borrowing the second light-emitting portion 22b from this group will experience a missing second light-emitting portion 22b. This ensures that at least some light-emitting element groups will exhibit color skipping at wide viewing angles due to the missing second light-emitting portion 22b, and that at least some light-emitting element groups 20 will display blurred or disordered information at wide viewing angles. This achieves confidentiality of the display information of at least some light-emitting element groups at wide viewing angles, thereby ensuring the confidentiality of the display information throughout the entire display panel and realizing the privacy function.

[0066] Furthermore, such as Figures 3 to 5As shown, the light-emitting element group 20 may include a first-color light-emitting element 2R, a second-color light-emitting element 2B, and two third-color light-emitting elements 2G, that is, the light-emitting element group 20 can be an RGBG structure light-emitting element group. Thus, in at least a portion of the same light-emitting element group 20, in privacy mode, there are one to three non-emitting second light-emitting portions 22b. These non-emitting second light-emitting portions 22b ensure that the light-emitting element 20 and other light-emitting element groups that utilize the second light-emitting portions 22b in this group all exhibit the absence of second light-emitting portions 22b, thereby achieving privacy of the display information in at least a portion of the light-emitting element group in the wide viewing angle direction, and thus achieving privacy of the display information in the entire display panel, realizing the privacy function. Furthermore, as... Figures 3 to 5 As shown, in the same light-emitting element group 20, the first color light-emitting element 2R, the second color light-emitting element 2B, and the third color light-emitting element 2G can have a variety of different arrangements, and the embodiments of this application do not limit this.

[0067] It should be noted that, in combination Figure 1 and Figure 2 As shown, the area outside the first opening 31 and the second opening 32 in the light-shielding structure 3 is the area where the light-shielding portion of the light-shielding structure is set. Figure 1 The light-shielding structure is not shown in the image to clearly illustrate the light-emitting element; however, the light-shielding structure can be found in [reference needed]. Figure 2 As shown. Furthermore, the light-shielding structure is not shown in the subsequent top views of the display panel, and will not be described further.

[0068] In summary, the display panel provided in this application includes light-emitting elements, a light-shielding structure, and a pixel definition layer. By reasonably setting the correspondence between the positions of the light-emitting elements, the openings and light-shielding portions in the light-emitting structure, and the positions of the pixel openings in the pixel definition layer, the first light-emitting element emits light normally in both the forward and wide viewing angles, the first light-emitting portion emits light normally in the forward viewing angle, and the second light-emitting portion emits light normally in the wide viewing angle. Furthermore, by setting the emission timing of the light-emitting elements and light-emitting portions in different display modes, the display panel can display normally at different viewing angles in the shared mode, while some content is missing in the privacy mode at wide viewing angles, thus achieving a privacy function. Moreover, by setting each light-emitting element group to include at least one first light-emitting element and at least one second light-emitting element, it is ensured that each light-emitting element group can achieve normal display in the shared mode, while at least some light-emitting element groups experience blurred or disordered display information at wide viewing angles in the privacy mode, thus ensuring the confidentiality of the display information in at least some light-emitting element groups at wide viewing angles, thereby achieving the confidentiality of the display information in the entire display panel and realizing a privacy function.

[0069] Optional, continue to refer to Figure 1 , Figures 3-5As shown, in the first light-emitting element 21 and the second light-emitting element 22 with the same light emission color, the pixel opening area of ​​the first light-emitting element 21 is S1, the pixel opening area of ​​the first light-emitting portion 22a is S2, and the pixel opening area of ​​the second light-emitting portion 22b is S3; wherein, S1>S3, S2>S3, and 80%≤S1 / S2≤120%.

[0070] Among the first light-emitting element 21 and the second light-emitting element 22, which emit the same color light, the pixel opening S1 of the first light-emitting element 21, the pixel opening area S2 of the first light-emitting portion 22a, and the pixel opening area S3 of the second light-emitting portion 22b satisfy the following relationship: S1 > S3, S2 > S3. That is, the pixel opening area of ​​the first light-emitting element 21 is larger than that of the second light-emitting portion 22b, and the pixel opening area of ​​the first light-emitting portion 22a is larger than that of the second light-emitting portion 22b. In other words, both the first light-emitting portion 21 and the first light-emitting portion 22a have a large light-emitting area. Thus, in both sharing mode and privacy mode, the first light-emitting element 21 and the first light-emitting portion 22a can fully display the content, providing a good display effect and ensuring normal display of the display panel.

[0071] Furthermore, the pixel opening S1 of the first light-emitting element 21 and the pixel opening area S2 of the first light-emitting portion 22a satisfy 80%≤S1 / S2≤120%, that is, the pixel opening area of ​​the first light-emitting element 21 and the pixel opening area of ​​the first light-emitting portion 22a are equivalent or similar, ensuring that the first light-emitting element 21 and the first light-emitting portion 22a have equivalent or similar display effects in both sharing mode and privacy mode, at least ensuring the display effect under normal viewing angle.

[0072] Further reference Figure 1 , Figures 3 to 5 As shown, the shape of at least one of the first pixel opening 41, the first pixel opening portion 42a, and the second pixel opening 42b includes a circle.

[0073] like Figure 1 , Figures 3 to 5 As shown, the shape of at least one of the first pixel opening 41, the first pixel opening portion 42a, and the second pixel opening 42b is circular. This ensures that at least one of the first pixel opening 41, the first pixel opening portion 42a, and the second pixel opening 42b has a regular shape and avoids optical diffraction problems caused by sharp angles, thereby improving the light emission effect and display effect of the display panel.

[0074] Optional, such as Figure 1 , Figures 3 to 5As shown, the shapes of the first pixel opening 41, the first pixel opening portion 42a, and the second pixel opening 42b can all be set to be circular. This ensures that the light emitted from the first pixel opening 41, the first pixel opening portion 42a, and the second pixel opening 42b can avoid optical diffraction problems to the greatest extent, thus fully guaranteeing the display effect of the display panel.

Figure 12 This is a schematic diagram of another display panel structure provided in an embodiment of this application, combined with... Figure 1 , Figures 6 to 12 As shown, the display panel also includes a first color light-emitting element 2R, a second color light-emitting element 2B, and a third color light-emitting element 2G. The first color light-emitting element 2R, the second color light-emitting element 2B, and the third color light-emitting element 2G are all different from red, blue, and green light-emitting elements. The display panel also includes multiple light-emitting element columns CO arranged along a first direction (X2 direction as shown in the figure, hereinafter referred to as the first direction X2 in the explanation) and multiple light-emitting element rows RO arranged along a second direction (X3 direction as shown in the figure, hereinafter referred to as the second direction X3 in the explanation). The first direction X2 and the second direction X3 intersect. The i-th row of light-emitting elements RO... i Includes a first color light-emitting element 2R and a third color light-emitting element 2G arranged alternately along the first direction X2; the (i+1)th row of light-emitting elements RO i+1 Includes a second-color light-emitting element 2B and a third-color light-emitting element 2G arranged alternately along the first direction X2; the j-th column of light-emitting elements CO j Includes a first-color light-emitting element 2R and a third-color light-emitting element 2G arranged alternately along the second direction X3; and a (j+1)th column of light-emitting elements CO. j+1 It includes a second-color light-emitting element 2B and a third-color light-emitting element 2G arranged alternately along the second direction X3; where i and j are both positive integers.

[0076] Figure 1 , Figures 6 to 12Various arrangements of the first and second light-emitting elements of different colors are shown, such as... Figure 1 , Figures 6 to 12 As shown, the display panel includes multiple rows (RO) and columns (CO) of light-emitting elements; multiple light-emitting elements in the same row (RO) are arranged along a first direction X2, and multiple rows (RO) are arranged along a second direction X3; multiple light-emitting elements in the same column (CO) are arranged along the second direction X3, and multiple columns (CO) are arranged along the first direction X2. In two adjacent rows (RO) arranged along the second direction X3, the arrangement of light-emitting elements of different colors differs; for example, in the i-th row (RO)... i Including a first color light-emitting element 2R and a third color light-emitting element 2G arranged alternately along the first direction X2, and the (i+1)th row of light-emitting elements RO i+1 This includes second-color light-emitting elements 2B and third-color light-emitting elements 2G arranged alternately along the first direction X2. Furthermore, in two adjacent columns of light-emitting elements CO arranged along the first direction X2, the arrangement of light-emitting elements of different colors differs; for example, in the j-th column of light-emitting elements CO… j Includes a first-color light-emitting element 2R and a third-color light-emitting element 2G arranged alternately along the second direction X3; and a (j+1)th column of light-emitting elements CO. j+1 This includes a second-color light-emitting element 2B and a third-color light-emitting element 2G arranged alternately along the second direction X3. This ensures a uniform and regular arrangement of the first-color light-emitting element 2R, the second-color light-emitting element 2B, and the third-color light-emitting element 2G along the first direction X2 and the second direction X3. Furthermore, the first-color light-emitting element 2R, the second-color light-emitting element 2B, and the third-color light-emitting element 2G are all different from each other (red, blue, and green). This further ensures a uniform and regular arrangement of different colors of light-emitting elements along the first direction X2 and the second direction X3, guaranteeing better display rendering effects between different colors and further ensuring the color display effect of the display panel. Simultaneously, the distribution density of the third-color light-emitting element 2G is greater than that of the first-color light-emitting elements 2R and the second-color light-emitting elements 2B. The third-color light-emitting element 2G can be a green light-emitting element. This arrangement aligns with the physiological characteristic that the human eye is most sensitive to green light, ensuring that a higher visual clarity display effect can be achieved with lower power consumption.

[0077] It should be noted that the light-emitting element rows and columns in the embodiments of this application can be understood as collections of light-emitting elements formed by multiple light-emitting elements arranged along a specific direction. For example, a collection of light-emitting elements formed by multiple light-emitting elements arranged along the first direction X2 can be a light-emitting element row, and a collection of light-emitting elements formed by multiple light-emitting elements arranged along the second direction X3 can be a light-emitting element column. In subsequent embodiments, a collection of light-emitting elements formed by multiple light-emitting elements arranged along a third direction (X4 direction as shown in the figure, which will be used as an example in the following description) can also be a light-emitting element row, and a collection of light-emitting elements formed by multiple light-emitting elements arranged along a fourth direction (X5 direction as shown in the figure, which will be used as an example in the following description) can also be a light-emitting element column. The arrangement direction of multiple light-emitting elements in a light-emitting element row is not unique, and the arrangement direction of multiple light-emitting elements in a light-emitting element column is not unique.

[0078] Continue to refer to Figure 1 , Figures 6 to 12 As shown, the display panel also includes multiple light-emitting element columns CO arranged along a third direction X4 and multiple light-emitting element rows RO arranged along a fourth direction X5; wherein, the third direction X4 intersects with the first direction X2, the second direction X3 and the fourth direction X5, and the fourth direction X5 intersects with the first direction X2 and the second direction X3; wherein, the p-th row of light-emitting elements RO p Includes a first color light-emitting element 2R and a second color light-emitting element 2B arranged alternately along the third direction X4; row RO of the (p+1)th light-emitting element. p+1 Includes multiple third-color light-emitting elements 2G arranged along the third direction X4; column q of light-emitting elements CO q Includes a first color light-emitting element 2R and a second color light-emitting element 2B arranged alternately along the fourth direction X5; and a (q+1)th column of light-emitting elements CO. q+1 It includes multiple third-color light-emitting elements 2G arranged along the fourth direction X5; p and q are both positive integers.

[0079] Figure 1 , Figures 6 to 12 Various arrangements of the first and second light-emitting elements of different colors are shown, such as... Figure 1 , Figures 6 to 12 As shown, the display panel includes multiple rows (RO) and columns (CO) of light-emitting elements. Multiple light-emitting elements in the same row (RO) are arranged along a third direction (X4), and multiple rows (RO) are arranged along a fourth direction (X5). Similarly, multiple light-emitting elements in the same column (CO) are arranged along a fourth direction (X5), and multiple columns (CO) are arranged along a third direction (X4). In two adjacent rows (RO) arranged along the fourth direction (X5), the arrangement of light-emitting elements of different colors differs; for example, in the p-th row (RO)... pIncluding a first color light-emitting element 2R and a second color light-emitting element 2B arranged alternately along the third direction X4, and the (p+1)th row of light-emitting elements RO p+1 This includes multiple third-color light-emitting elements 2G of the same color arranged along the third direction X4. Furthermore, in two adjacent columns CO of light-emitting elements arranged along the third direction X4, the arrangement of light-emitting elements of different colors differs; for example, in the qth column CO... q Includes a first color light-emitting element 2R and a second color light-emitting element 2B arranged alternately along the fourth direction X5; and a (q+1)th column of light-emitting elements CO. q+1 This includes multiple third-color light-emitting elements 2G of the same color arranged along the fourth direction X5. This ensures a uniform and regular arrangement of the first-color light-emitting elements 2R, the second-color light-emitting elements 2B, and the third-color light-emitting elements 2G along the third direction X4 and the fourth direction X5. Furthermore, the first-color light-emitting elements 2R, the second-color light-emitting elements 2B, and the third-color light-emitting elements 2G are all different from each other (red, blue, and green). This further ensures a uniform and regular arrangement of different colored light-emitting elements along the third direction X4 and the fourth direction X5, guaranteeing better display rendering effects between different colored light-emitting elements and further ensuring the color display effect of the display panel. Simultaneously, the distribution density of the third-color light-emitting elements 2G is greater than that of the first-color light-emitting elements 2R and the second-color light-emitting elements 2B. The third-color light-emitting elements 2G can be green light-emitting elements. This arrangement aligns with the physiological characteristic that the human eye is most sensitive to green light, ensuring that a higher visual clarity display effect can be achieved with lower power consumption.

[0080] Optional, continue to refer to Figure 1 and Figure 2 As shown, the display panel also includes a pixel circuit 5 and a signal line 6 located on one side of the substrate; the signal line 6 includes a scan signal line 61 and a data signal line 62, and the pixel circuit 5 is electrically connected to the scan signal line 61, the data signal line 62 and the light-emitting element 2 respectively; the scan signal line 61 extends along a third direction X4, and the data signal line 62 extends along a fourth direction X5.

[0081] Combination Figure 1 and Figure 2 As shown, the display panel also includes a plurality of pixel circuits 5 and signal lines 6 located on one side of the substrate 1. The pixel circuits 5 may include transistors and capacitors. For example, the pixel circuits 5 may include at least two transistors and at least one capacitor. That is, the pixel circuits 5 may be a "2T1C" structure, a "6T2C" structure, a "7T1C" structure, or an "8T1C" structure. Here, "T" represents a transistor and "C" represents a capacitor. The specific structure of the pixel circuits 5 is not limited in this embodiment. Figure 2The pixel circuit is represented only by the transistors shown. The signal line 6 may include a scan signal line 61, a data signal line 62, and a power signal line (not shown in the figure). The pixel circuit 5 is electrically connected to the scan signal line 61, the data signal line 62, and the power signal line, respectively, and is used to convert the data signal provided by the data signal line 62 and the power signal provided by the power signal line into a driving current signal to drive the light-emitting element 2 to emit light, so as to achieve the purpose of driving the light-emitting element 2 to display light emission.

[0082] Furthermore, the scan signal line 61 extends along the third direction X4, and the data signal line 62 extends along the fourth direction X5. That is, the extension direction of the scan signal line 61 is the same as that of the p-th row of light-emitting elements RO. p and row (p+1) of the light-emitting element row RO p+1 The multiple light-emitting elements 2 are arranged in the same direction, and the extension direction of the data signal line 62 is the same as that of the qth column of light-emitting elements CO. q and column (q+1) of light-emitting elements CO q+1 The multiple light-emitting elements 2 are arranged in the same direction, which ensures that the arrangement direction of the light-emitting elements 2 is consistent with the extension direction of the signal lines 6, thus ensuring a neat arrangement of the light-emitting elements 2 and the signal lines 6. Furthermore, the scan signal lines 61 can be positioned between adjacent rows of light-emitting elements (RO), and the data signal lines 62 can be positioned between adjacent columns of light-emitting elements (CO). This reduces the impact of the signal lines 6 on the arrangement of the light-emitting elements 2, such as affecting the flatness of the anode surface in the light-emitting elements 2, thus ensuring the overall light emission effect of the light-emitting elements 2.

[0083] It should be noted that, in order to clearly show Figure 1 The light-emitting element in Figure 1 Only one scan signal line 61 and one data signal line 62 are shown as an example. It will be understood that the display panel includes multiple scan signal lines 61 and multiple data signal lines 62, with the multiple scan signal lines 61 arranged along the fourth direction X5 and the multiple data signal lines 62 arranged along the third direction X4, which will not be described in detail here.

[0084] Based on the above embodiments, continue to refer to Figure 1 , Figures 6 to 12As shown, the first color light-emitting element 2R includes a first color first light-emitting element 21R and a first color second light-emitting element 22R; the second color light-emitting element 2B includes a second color first light-emitting element 21B and a second color second light-emitting element 22B; the third color light-emitting element 2G includes a third color first light-emitting element 21G and a third color second light-emitting element 22G; the first light-emitting element 21 includes a first color first light-emitting element 21R, a second color first light-emitting element 21B, and a third color first light-emitting element 21G; the second light-emitting element 22 includes a first color second light-emitting element 22R, a second color second light-emitting element 22B, and a third color second light-emitting element 22G; the display panel also includes a plurality of light-emitting element columns CO arranged along a third direction X4 and a plurality of light-emitting element rows RO arranged along a fourth direction X5; wherein, the third direction X4 intersects with the first direction X2, the second direction X3, and the fourth direction X5, and the fourth direction X5 intersects with the first direction X2 and the second direction X3; wherein, in the same light-emitting element row, the first light-emitting elements 21 and the second light-emitting elements 22 of the same color are alternately arranged along the third direction X4.

[0085] like Figure 1 , Figures 6 to 12As shown in the embodiment of this application, the first light-emitting element 21 includes a first-color first light-emitting element 21R, a second-color first light-emitting element 21B, and a third-color first light-emitting element 21G. The second light-emitting element 22 includes a first-color second light-emitting element 22R, a second-color second light-emitting element 22B, and a third-color second light-emitting element 22G. That is, both the first light-emitting element 21 and the second light-emitting element 22 include multiple light-emitting elements of different colors. Thus, in the sharing mode, the first-color first light-emitting element 21R, the second-color first light-emitting element 21B, the third-color first light-emitting element 21G, the first-color second light-emitting element 22R, the second-color second light-emitting element 22B, and the third-color second light-emitting element 22G all emit light, achieving color display with both a positive viewing angle and a wide viewing angle in the sharing mode. In the privacy mode, the first-color first light-emitting element 21R, the second-color first light-emitting element 21B, the third-color first light-emitting element 21G, the first-color second light-emitting element 21R, the second-color second light-emitting element 21B, and the third-color second light-emitting element 22G all emit light, achieving color display with both a positive viewing angle and a wide viewing angle in the sharing mode. The first light-emitting portion 22a of the first light-emitting element 22R, the first light-emitting portion 22a of the second light-emitting element 22B, and the first light-emitting portion 22a of the third light-emitting element 22G emit light normally, realizing a positive viewing angle color display in the privacy mode; and the second light-emitting portion 22b of the first light-emitting element 22R, the second light-emitting portion 22b of the second light-emitting element 22B, and the second light-emitting portion 22b of the third light-emitting element 22G do not emit light, realizing the absence of the large viewing angle light-emitting portion in the privacy mode, causing at least some light-emitting element groups to have blurred or disordered large viewing angle display information in the privacy mode, thus achieving the privacy function by keeping the display information of at least some light-emitting element groups confidential in the large viewing angle direction.

[0086] Furthermore, within the same row RO of light-emitting elements, the first light-emitting element 21 and the second light-emitting element 22 of the same color are arranged alternately along the third direction X4. That is, the first light-emitting element 21R and the second light-emitting element 22R of the first color are arranged alternately in the third direction X4, and / or, the first light-emitting element 21B and the second light-emitting element 22B of the second color are arranged alternately in the third direction X4, and / or, the first light-emitting element 21G and the second light-emitting element 22G of the third color are arranged alternately in the third direction X4. In this way, the first light-emitting element 21, which includes light emission from a wide viewing angle, and the second light-emitting element 22R, which does not include light emission from a wide viewing angle, are evenly distributed in the third direction X4, which can ensure that the display panel has a uniform brightness in the third direction X4. To avoid the situation where the first light-emitting element 21, which contains a wide-viewing-angle light emission, is densely packed in the third direction X4, resulting in a large display brightness in this area, and the second light-emitting element 22, which does not contain a wide-viewing-angle light emission, is densely packed in the third direction X4, resulting in a small display brightness in this area, this method avoids uneven brightness display areas on the light-emitting display panel in the third direction X4, thus ensuring good uniformity of display brightness on the display panel.

[0087] For details, please refer to [link / reference]. Figure 1 , Figures 6 to 12 As shown, the p-th row of light-emitting elements is RO. p In the diagram, the first color first light-emitting element 21R and the first color second light-emitting element 22R are arranged alternately along the third direction X4, and the second color first light-emitting element 21B and the second color second light-emitting element 22B are arranged alternately along the third direction X4; p is a positive integer; the (p+1)th row of light-emitting elements is row RO. p+1 In the middle, the first light-emitting element 21G of the third color and the second light-emitting element 22G of the third color are arranged alternately along the third direction X4.

[0088] like Figure 1 , Figures 6 to 12 As shown, the two adjacent rows of light-emitting elements RO arranged in the fourth direction X5 include the p-th row of light-emitting elements RO. p And the (p+1)th row of light-emitting elements ROp+1, the pth row of light-emitting elements RO p In this configuration, the first-color light-emitting element 2R and the second-color light-emitting element 2B are arranged alternately along the third direction X4. Furthermore, the first-color first-color light-emitting element 21R and the first-color second-color light-emitting element 22R are arranged alternately along the third direction X4, and the second-color first-color light-emitting element 21B and the second-color second-color light-emitting element 22B are arranged alternately along the third direction X4. This ensures good uniformity of the emitted brightness of the first and second colors along the third direction X4. Additionally, in the (p+1)th row of light-emitting elements, row RO... p+1 In this configuration, the first light-emitting element 21G and the second light-emitting element 22G of the third color are alternately arranged along the third direction X4, thus ensuring good uniformity of the emitted light brightness of the third color along the third direction X4. This further ensures that the first, second, and third colors all have good uniformity of emitted light brightness throughout the entire display area, while also ensuring good consistency in the mixing of different colors, thus guaranteeing good uniformity of emitted light brightness in the color display of the display panel.

[0089] Optional, continue to refer to Figure 1 , Figures 6 to 12 As shown, in the same light-emitting element column CO, the first group GR1 and the second group GR2 are arranged alternately along the fourth direction X5; wherein, the first group GR1 includes two first light-emitting elements 21 of the same color, and the second group GR2 includes two second light-emitting elements 22 of the same color.

[0090] like Figure 1 , Figures 6 to 12As shown, the same light-emitting element column CO includes multiple groups GR. A group GR can be understood as a set of light-emitting elements formed by arranging two light-emitting elements 2 of the same color in the fourth direction X5. Furthermore, two groups GR arranged adjacent to each other in the fourth direction X5 include a first group GR1 and a second group GR2. The light-emitting elements contained in the first group GR1 and the second group GR2 have the same emission color, and the first group GR1 includes two first light-emitting elements 21, and the second group GR2 includes two second light-emitting elements 22. Thus, in the same light-emitting element column CO formed by multiple light-emitting elements 2 arranged along the fourth direction X5, the first light-emitting elements 21 and the second light-emitting elements 22 of the same color are arranged alternately in pairs along the fourth direction X5. That is, the first group GR1 containing two first light-emitting elements 21R of the first color and the second group GR2 containing two first light-emitting elements 22R of the first color are arranged alternately in the fourth direction X5; and / or, the first group GR1 containing two first light-emitting elements 21B of the second color and the second group GR2 containing two second light-emitting elements 22B of the second color are arranged alternately in the fourth direction X5; and / or, the first group GR1 containing two first light-emitting elements 21G of the third color and the second group GR2 containing two second light-emitting elements 22G of the third color are arranged alternately in the fourth direction X5. In this way, the first group GR1 containing the first light-emitting elements 21 with a wide viewing angle and the second group GR2 without the second light-emitting elements 22R with a wide viewing angle are evenly distributed in the fourth direction X5, which can ensure that the display panel has a uniform brightness in the fourth direction X5. To avoid the situation where the first group of GR1, which contains the first light-emitting element 21 with a wide viewing angle, is densely packed in the fourth direction X5, resulting in a large display brightness in this area, and the second group of GR2, which does not contain the second light-emitting element 22 with a wide viewing angle, is densely packed in the fourth direction X5, resulting in a small display brightness in this area, this method avoids uneven brightness display areas on the light-emitting display panel in the fourth direction X5, thus ensuring good uniformity of display brightness on the display panel.

[0091] Further reference Figure 1 , Figures 6 to 12 As shown, the first group GR1 includes the first subgroup GR11, the second subgroup GR12, and the third subgroup GR13; the second group GR2 includes the fourth subgroup GR21, the fifth subgroup GR22, and the sixth subgroup GR23; the q-th column of light-emitting elements is column CO. q In the diagram, the first subgroup GR11 and the fourth subgroup GR21 are arranged alternately along the fourth direction X5; the first subgroup GR11 includes two first-color first light-emitting elements 21R arranged adjacently along the fourth direction X5; the fourth subgroup GR21 includes two first-color second light-emitting elements 22R arranged adjacently along the fourth direction X5; q is a positive integer; the q-th column of light-emitting elements is column CO. qIn the middle, the second subgroup GR12 and the fifth subgroup GR22 are arranged alternately along the fourth direction X5; the second subgroup GR12 includes two second-color first light-emitting elements 21B arranged adjacently along the fourth direction X5; the fifth subgroup GR22 includes two second-color second light-emitting elements 22B arranged adjacently along the fourth direction X5; the (q+1)th column of light-emitting elements CO q+1 In the middle, the third subgroup GR13 and the sixth subgroup GR23 are arranged alternately along the fourth direction X5; the third subgroup GR13 includes two third-color first light-emitting elements 21G arranged adjacent to each other along the fourth direction X5; the sixth subgroup GR23 includes two third-color second light-emitting elements 22G arranged adjacent to each other along the fourth direction X5.

[0092] like Figure 1 , Figures 6 to 12 As shown, the two adjacent rows of light-emitting element columns CO on the third direction X4 include the q-th light-emitting element column CO. q And the (q+1)th column of light-emitting elements COq+1, the qth column of light-emitting elements CO q In this configuration, the first-color light-emitting element 2R and the second-color light-emitting element 2B are arranged alternately along the fourth direction X5, thus ensuring a good color mixing effect between the first and second colors. Furthermore, in the q-th column of light-emitting elements CO... q In this configuration, a first subgroup GR11 containing two first-color first-light-emitting elements 21R and a fourth subgroup GR21 containing two first-color second-light-emitting elements 22R are alternately arranged along the fourth direction X5, thus ensuring good uniformity of the emitted light brightness of the first color along the fourth direction X5. Furthermore, in the q-th column of light-emitting elements CO... q In this configuration, a second subgroup GR12 containing two second-color first light-emitting elements 21B and a fifth subgroup GR22 containing two second-color second light-emitting elements 22B are alternately arranged along the fourth direction X5, thus ensuring good uniformity of the emitted brightness of the second color along the fourth direction X5. Furthermore, in the (q+1)th column of light-emitting elements CO... q+1 In this configuration, the third subgroup GR13, containing two third-color first light-emitting elements 21G, and the sixth subgroup GR23, containing two third-color second light-emitting elements 22G, are alternately arranged along the fourth direction X5. This ensures good uniformity of the emitted light brightness of the third color along the fourth direction X5. Furthermore, it ensures good uniformity of emitted light brightness for the first, second, and third colors throughout the entire display area, while also ensuring good consistency in the mixing of different colors, thus guaranteeing good uniformity of emitted light brightness for the color display panel.

Figure 14This is a schematic diagram of another arrangement of the first color light-emitting elements provided in an embodiment of this application.

Figure 14 The arrangement of the first color light-emitting elements and Figure 6 , Figure 8 , Figure 10 and Figure 12 The arrangement of the first color light-emitting elements is the same. For example... Figure 13 and Figure 14 As shown, the display panel provided in this application embodiment may further include a first light-emitting group UN1, a second light-emitting group UN2, a third light-emitting group UN3, and a fourth light-emitting group UN4; the first light-emitting group UN1 includes four first-color light-emitting elements 2R arranged adjacently along the first direction X2, and along the first direction X2, two adjacent first-color first light-emitting elements 21R are located between two adjacent first-color second light-emitting elements 22R; the second light-emitting group UN2 includes four first-color light-emitting elements 2R arranged adjacently along the first direction X2, and along the first direction X2, two adjacent first-color second light-emitting elements 22R are located between two adjacent first-color first light-emitting elements 21R; the third light-emitting group UN3 includes four first-color first light-emitting elements 21R arranged adjacently along the second direction X3; the fourth light-emitting group UN4 includes four first-color second light-emitting elements 22R arranged adjacently along the second direction X3; the i-th row of light-emitting elements RO i In the middle, along the first direction X2, the first light-emitting group UN1 and the second light-emitting group UN2 are arranged alternately; in the j-th column of light-emitting elements, CO j Along the second direction X3, the third light-emitting group UN3 and the fourth light-emitting group UN4 are arranged alternately.

[0094] like Figure 13 and Figure 14 As shown, the i-th row of light-emitting elements is row RO. i The system includes a first light-emitting group UN1 and a second light-emitting group UN2 arranged alternately along the first direction X2. The first light-emitting group UN1 includes four first-color light-emitting elements 2R arranged adjacently along the first direction X2, and along the first direction X2, two adjacent first-color light-emitting elements 21R are located between two adjacent first-color second-color light-emitting elements 22R. The second light-emitting group UN2 includes four first-color light-emitting elements 2R arranged adjacently along the first direction X2, and along the first direction X2, two adjacent first-color second-color light-emitting elements 22R are located between two adjacent first-color first-color light-emitting elements 21R. This ensures that in the i-th row of light-emitting elements RO... iIn the first color, the first light-emitting element 21R and the second light-emitting element 22R are evenly and dispersedly arranged. That is, in privacy mode, the first color light-emitting element 21R containing light emitted from a wide viewing angle and the second color light-emitting element 22R not containing light emitted from a wide viewing angle are evenly and dispersedly arranged, thus ensuring good uniformity of the first color's emitted brightness in the first direction X2. This avoids the first color display brightness in the first direction X2 being too high due to the concentrated and dense arrangement of the first color light-emitting element 21R containing light emitted from a wide viewing angle, and the first color display brightness in the first direction X2 being too low due to the concentrated and dense arrangement of the second color light-emitting element 22R not containing light emitted from a wide viewing angle. In other words, it avoids uneven brightness areas of the first color on the display panel in the first direction X2, ensuring good uniformity of the first color's displayed brightness. Furthermore, in the j-th column of light-emitting elements, CO... j The system includes a third light-emitting group UN3 and a fourth light-emitting group UN4. The third light-emitting group UN3 includes four first-color first light-emitting elements 21R arranged adjacently along the second direction X3, and the fourth light-emitting group UN4 includes four first-color second light-emitting elements 22R arranged adjacently along the second direction X3. This ensures that the light-emitting element column CO in the j-th column is... j In the design, the first-color first light-emitting element 21R and the first-color second light-emitting element 22R are arranged in a four-by-four alternating pattern, meaning they are evenly and dispersedly arranged. In other words, in privacy mode, the first-color first light-emitting element 21R containing light emitted from a wide viewing angle and the first-color second light-emitting element 22R not containing light emitted from a wide viewing angle are evenly and dispersedly arranged, thus ensuring good uniformity of the first color's emitted brightness in the second direction X3. This avoids situations where the first-color first light-emitting element 21R containing light emitted from a wide viewing angle is densely packed in the second direction X3, resulting in excessive brightness in that area, or where the first-color second light-emitting element 22R not containing light emitted from a wide viewing angle is densely packed in the second direction X3, resulting in insufficient brightness in that area. In other words, it avoids uneven brightness areas of the first color on the display panel in the second direction X3, ensuring good uniformity of the first color's displayed brightness.

Figure 16The arrangement of the second color light-emitting elements and Figure 7 , Figure 8 , Figure 11 and Figure 12 The arrangement of the second color light-emitting elements is the same. For example... Figure 15 and Figure 16 As shown, the display panel provided in this application embodiment may further include a fifth light-emitting group UN5, a sixth light-emitting group UN6, a seventh light-emitting group UN7, and an eighth light-emitting group UN8; the fifth light-emitting group UN5 includes four second-color first light-emitting elements 21B arranged adjacently along the first direction X2; the sixth light-emitting group UN6 includes four second-color second light-emitting elements 22B arranged adjacently along the first direction X2; the seventh light-emitting group UN7 includes four second-color light-emitting elements 2B arranged adjacently along the second direction X3, and along the second direction X3, two adjacent second-color first light-emitting elements 21B are located between two adjacent second-color second light-emitting elements 22B; the eighth light-emitting group UN8 includes four second-color light-emitting elements 2B arranged adjacently along the second direction X3, and along the second direction X3, two adjacent second-color second light-emitting elements 22B are located between two adjacent second-color first light-emitting elements 21B; the (i+1)th row of light-emitting elements RO i+1 In the middle, along the first direction X2, the fifth light-emitting group UN5 and the sixth light-emitting group UN6 are arranged alternately; the (j+1)th column of light-emitting elements is column CO. j+1 In the middle, along the second direction X3, the seventh light-emitting group UN7 and the eighth light-emitting group UN8 are arranged alternately.

[0096] like Figure 15 and Figure 16 As shown, the (i+1)th row of light-emitting elements is row RO. i+1 It includes a fifth light-emitting group UN5 and a sixth light-emitting group UN6 arranged alternately in the first direction X2. The fifth light-emitting group UN5 includes four second-color first light-emitting elements 21B arranged adjacently along the first direction X2, and the sixth light-emitting group UN6 includes four second-color second light-emitting elements 22B arranged adjacently along the first direction X2. This ensures that the light-emitting element row RO in the (i+1)th row... i+1In the middle, the second-color first light-emitting element 21B and the second-color second light-emitting element 22B are arranged in a four-by-four alternating pattern, that is, the second-color first light-emitting element 21B and the second-color second light-emitting element 22B are evenly and dispersedly arranged. In other words, in privacy mode, the second-color first light-emitting element 21B containing wide-viewing-angle light and the second-color second light-emitting element 22B not containing wide-viewing-angle light are evenly and dispersedly arranged, thus ensuring good uniformity of the second-color light emission brightness in the first direction X2. This avoids the second-color display brightness in the first direction X2 being too high due to the dense concentration of the second-color first light-emitting element 21B containing wide-viewing-angle light, and the second-color second light-emitting element 22B not containing wide-viewing-angle light in the first direction X2 being too low, thus avoiding uneven brightness areas of the second color on the display panel in the first direction X2, and ensuring good uniformity of the second-color display brightness. Furthermore, the (j+1)th column of light-emitting elements CO... j+1 The system includes a seventh light-emitting group UN7 and an eighth light-emitting group UN8 arranged alternately in the second direction X3. The seventh light-emitting group UN7 includes four second-color light-emitting elements 2B arranged adjacently along the second direction X3, and along the second direction X3, two adjacent second-color first light-emitting elements 21B are located between two adjacent second-color second light-emitting elements 22B. The eighth light-emitting group UN8 includes four second-color light-emitting elements 2B arranged adjacently along the second direction X3, and along the second direction X3, two adjacent second-color second light-emitting elements 22B are located between two adjacent second-color first light-emitting elements 21B. Thus, the second-color first light-emitting elements 21B and the second-color second light-emitting elements 22B are evenly and dispersedly arranged. That is, in the privacy mode, the second-color first light-emitting elements 21B containing wide-angle light emission rays and the second-color second light-emitting elements 22B not containing wide-angle light emission rays are evenly and dispersedly arranged, thus ensuring good uniformity of the second-color light emission brightness in the second direction X3. To avoid the second color display brightness in this area being too high due to the concentrated and dense arrangement of the first light-emitting element 21B containing the second color with a wide viewing angle in the second direction X3, and the second color display brightness in this area being too low due to the concentrated and dense arrangement of the second light-emitting element 22B without the second color with a wide viewing angle in the second direction X3, in other words, to avoid the appearance of uneven brightness display areas of the second color on the light-emitting display panel in the second direction X3, and to ensure good uniformity of the second color display brightness of the display panel.

[0097] Optional, Figure 17 This is a schematic diagram of the arrangement of a third-color light-emitting element provided in an embodiment of this application. Figure 18 This is a schematic diagram of another arrangement of third-color light-emitting elements provided in an embodiment of this application. Figure 17 The arrangement of the third color light-emitting elements and Figure 1 , Figure 6 , Figure 7 and Figure 8 The third color light-emitting element is arranged in the same way. Figure 18 The arrangement of the third color light-emitting elements and Figure 9 , Figure 10 , Figure 11 and Figure 12 The third color light-emitting element is arranged in the same way. For example... Figure 17 and Figure 18 As shown, the display panel provided in this application embodiment may further include a ninth light-emitting group UN9, a tenth light-emitting group UN10, an eleventh light-emitting group UN11, and a twelfth light-emitting group UN12; the ninth light-emitting group UN9 includes two third-color first light-emitting elements 21G arranged adjacently along the first direction X2; the tenth light-emitting group UN10 includes two third-color second light-emitting elements 22G arranged adjacently along the first direction X2; the eleventh light-emitting group UN11 includes two third-color first light-emitting elements 21G arranged adjacently along the second direction X3; the twelfth light-emitting group UN12 includes two third-color second light-emitting elements 22G arranged adjacently along the second direction X3; the i-th row of light-emitting elements RO i In the middle, along the first direction X2, the ninth light-emitting group UN9 and the tenth light-emitting group UN10 are arranged alternately; the (i+1)th row of light-emitting elements is row RO. i+1 In the middle, along the first direction X2, the ninth light-emitting group UN9 and the tenth light-emitting group UN10 are arranged alternately; in the j-th column of light-emitting elements, CO j Along the second direction X3, the eleventh light-emitting group UN11 and the twelfth light-emitting group UN12 are arranged alternately; the (j+1)th column of light-emitting elements is column CO. j+1 In the middle, along the second direction X3, the eleventh light-emitting group UN11 and the twelfth light-emitting group UN12 are arranged alternately.

[0098] like Figure 17 and Figure 18 As shown, the i-th row of light-emitting elements is row RO. i and the (i+1)th row of light-emitting elements RO i+1 Each includes a ninth light-emitting group UN9 and a tenth light-emitting group UN10 arranged alternately along the first direction X2. The ninth light-emitting group UN9 includes two third-color first light-emitting elements 21G arranged adjacently along the first direction X2, and the tenth light-emitting group UN10 includes two third-color second light-emitting elements 22G arranged adjacently along the first direction X2. This ensures that in the i-th row of light-emitting elements, row RO... i and the (i+1)th row of light-emitting elements RO i+1In the middle, the third-color first light-emitting element 21G and the third-color second light-emitting element 22G are arranged alternately in pairs, that is, the third-color first light-emitting element 21G and the third-color second light-emitting element 22G are evenly and dispersedly arranged. In other words, in privacy mode, the third-color first light-emitting element 21G containing wide-viewing-angle light and the third-color second light-emitting element 22G not containing wide-viewing-angle light are evenly and dispersedly arranged, thus ensuring good uniformity of the third-color light emission brightness in the first direction X2. This avoids the third-color display brightness in the first direction X2 being too high due to the concentrated and dense arrangement of the third-color first light-emitting element 21G containing wide-viewing-angle light, and the third-color display brightness in the first direction X2 being too low due to the concentrated and dense arrangement of the third-color second light-emitting element 22G not containing wide-viewing-angle light. In other words, it avoids uneven brightness areas of the third color on the display panel in the first direction X2, ensuring good uniformity of the third-color display brightness. Furthermore, the j-th column of light-emitting elements CO... j and column (j+1) of the light-emitting element CO j+1 Both include an eleventh light-emitting group UN11 and a twelfth light-emitting group UN12 arranged alternately in the second direction X3. The eleventh light-emitting group UN11 includes two third-color first light-emitting elements 21G arranged adjacently along the second direction X3; the twelfth light-emitting group UN12 includes two third-color second light-emitting elements 22G arranged adjacently along the second direction X3. This ensures that in the j-th column of light-emitting elements CO j and column (j+1) of the light-emitting element CO j+1 In the design, the first light-emitting element 21G of the third color and the second light-emitting element 22G of the third color are arranged alternately in pairs, meaning they are evenly and dispersedly arranged. In other words, in privacy mode, the first light-emitting element 21G of the third color, which emits light from a wide viewing angle, and the second light-emitting element 22G of the third color, which does not emit light from a wide viewing angle, are evenly and dispersedly arranged, thus ensuring good uniformity of the third color's brightness in the second direction X3. This avoids the situation where the first light-emitting element 21G of the third color, which emits light from a wide viewing angle, is densely packed in the second direction X3, resulting in excessive brightness in that area, and conversely, the situation where the second light-emitting element 22G of the third color, which does not emit light from a wide viewing angle, is densely packed in the second direction X3, resulting in insufficient brightness in that area. In other words, it avoids uneven brightness areas of the third color on the display panel in the second direction X3, ensuring good uniformity of the third color's brightness on the display panel.

[0099] In summary, by reasonably setting the arrangement of the first and second light-emitting elements of the same color, as well as the arrangement of light-emitting elements of different colors, in the first, second, third, and fourth directions, good uniformity of the display of the first, second, and third colors can be ensured in different directions.

[0100] Furthermore, Figure 19 yes Figure 1 The diagram shows the arrangement of light-emitting elements visible on the corresponding display panel in privacy mode and at wide viewing angles. Figure 20 yes Figure 6 The diagram shows the arrangement of light-emitting elements visible on the corresponding display panel in privacy mode and at wide viewing angles.

Figure 22 yes Figure 8 The diagram shows the arrangement of light-emitting elements visible on the corresponding display panel in privacy mode and at wide viewing angles. Figure 23 yes Figure 9 The diagram shows the arrangement of light-emitting elements visible on the corresponding display panel in privacy mode and at wide viewing angles. Figure 24 yes Figure 10 The diagram shows the arrangement of light-emitting elements visible on the corresponding display panel in privacy mode and at wide viewing angles. Figure 25 yes Figure 11 The diagram shows the arrangement of light-emitting elements visible on the corresponding display panel in privacy mode and at wide viewing angles. Figure 26 yes Figure 12 The corresponding schematic diagram of the arrangement of light-emitting elements visible in privacy mode and at wide viewing angles is provided for reference. Figure 1 and Figure 19 , Figure 6 and Figure 20 , Figure 7 and Figure 21 , Figure 8 and Figure 22 , Figure 9 and Figure 23 , Figure 10 and Figure 24 , Figure 11 and Figure 25 as well as Figure 12 and Figure 26As shown, by reasonably setting the arrangement of the first and second light-emitting elements of the same color, and the arrangement of light-emitting elements of different colors, in the first, second, third, and fourth directions, it can be ensured that in the shared mode, the first light-emitting element 21, the first light-emitting section 22a, and the second light-emitting section 22b all emit light. Thus, the light emitted by the first light-emitting element 21 is visible in both the direct viewing angle and the wide viewing angle, the light emitted by the first light-emitting section 22a is visible in the direct viewing angle, and the light emitted by the second light-emitting section 22b is visible in the wide viewing angle. In other words, the light emitted by the first light-emitting element 21 and the second light-emitting element 22 is visible in both the direct viewing angle and the wide viewing angle, achieving normal display at different viewing angles. In the privacy mode and wide viewing angle, the light emitted by the first light-emitting section 22a is not visible due to the light-blocking structure, and the second light-emitting section 22b does not emit light. Thus, the light emitted by the second light-emitting element 22 is not visible in the wide viewing angle. Figures 19 to 26 As shown, the second light-emitting element 22 is not visible. This ensures that in privacy mode, color skipping occurs due to partial light loss in the wide viewing angle direction, causing the information displayed in the wide viewing angle to become blurry or disordered, thus achieving the confidentiality of the displayed information in the wide viewing angle direction.

[0101] Based on the above embodiments, continue to refer to Figures 1 to 12 As shown, the second light-emitting portion 22b surrounds the first light-emitting portion 22a. Thus, in the sharing mode, the second light-emitting portion 22b compensates for the wide-viewing-angle light of the first light-emitting portion 22a in all directions. That is, the second light-emitting portion 22b can compensate for the wide-viewing-angle light of the first light-emitting portion 22a in all directions, ensuring the wide-viewing-angle visual effect and brightness of the second light-emitting element 22 in the sharing mode, and ensuring good display effect in the sharing mode.

[0102] Based on the above embodiments, Figure 27 This is a schematic diagram of the structure of a second light-emitting element provided in an embodiment of this application, as shown below. Figure 27 As shown, the second light-emitting portion 22b surrounds a portion of the first light-emitting portion 22a; the second light-emitting portion 22b includes a first end B1 and a second end B2, the line connecting the first end B1 and the center O of the first light-emitting portion 22a is the first connecting line B1O, and the line connecting the second end B2 and the center O of the first light-emitting portion 22a is the second connecting line B2O; of the two included angles formed by the first connecting line B1O and the second connecting line B2O, the larger included angle α satisfies 180°≤α<360°.

[0103] like Figure 27As shown, the second light-emitting portion 22b includes a first end B1 and a second end B2. The first end B1 can be any point in one of the edge regions of the second light-emitting portion 22b, and the second end B2 can be any point in the other edge region of the second light-emitting portion 22b. The larger of the two included angles formed by the first connecting line B1O and the second connecting line B2O satisfies 180° ≤ α < 360°, meaning that starting from B1, a clockwise rotation of 180°–360° is required to reach B2. Alternatively, if the inner diameter of the second light-emitting portion 22b is circular, the angle range of the central arc angle corresponding to the arc B1B2 is 180°–360°. Figure 27 As shown, the azimuth angle corresponding to the first light-emitting portion 22a is 360°. This means that any point on the edge of the first light-emitting portion 22a, when rotated clockwise or counterclockwise back to that point, requires a 360° rotation. The larger of the two included angles α formed by the first line B1O and the second line B2O satisfies 180° ≤ α < 360°. Thus, although the second light-emitting portion 22b does not completely surround the first light-emitting portion 22a, it surrounds at least half of the area of ​​the first light-emitting portion 22a. This ensures that the second light-emitting portion 22b can compensate for the large-viewing-angle light of the first light-emitting portion 22a within a relatively large azimuth angle range. In other words, the second light-emitting portion 22b can compensate for the large-viewing-angle light of the first light-emitting portion 22a to a large extent, thus largely ensuring the large-viewing-angle visual effect and brightness of the second light-emitting element 22 in the shared mode, guaranteeing a good display effect in the shared mode.

[0104] Furthermore, Figure 28 This is a schematic diagram of the structure of two adjacent second light-emitting elements with the same emission color provided in an embodiment of this application, as shown below. Figure 28As shown, two adjacent second light-emitting elements with the same emitting color include a first second light-emitting element 221 and a second second light-emitting element 222; the first second light-emitting element 221 includes a first first light-emitting portion 22a1 and a first second light-emitting portion 22b1, with the first second light-emitting portion 22b1 surrounding a portion of the first first light-emitting portion 22a1; the second second light-emitting element 222 includes a second first light-emitting portion 22a2 and a second second light-emitting portion 22b2, with the second second light-emitting portion 22b2 surrounding a portion of the second first light-emitting portion 22a2; the display panel also... The system includes a first virtual line V1 and a second virtual line V2 arranged in parallel. The first virtual line V1 passes through the center O1 of the first first light-emitting portion 22a1 and intersects with the first second light-emitting portion 22b1 only at a first intersection position X1. The second virtual line V2 passes through the center O2 of the second first light-emitting portion 22a2 and intersects with the second second light-emitting portion 22b2 only at a second intersection position X2. The direction from the center O1 of the first first light-emitting portion 22a1 to the first intersection position X1 is opposite to the direction from the center O2 of the second first light-emitting portion 22a2 to the second intersection position X2.

[0105] like Figure 28 As shown, in the first and second light-emitting elements 221, the first and second light-emitting portions 22b1 partially surround the first and first light-emitting portions 22a1; in the second and second light-emitting elements 222, the second and second light-emitting portions 22b2 partially surround the second and first light-emitting portions 22a2. Two parallel virtual lines can be found in the display panel, such as a first virtual line V1 and a second virtual line V2. The first virtual line V1 passes through the center O1 of the first and first light-emitting portions 22a1 and intersects with the first and second light-emitting portions 22b1 only at a point X1. The second virtual line V2 passes through the center O2 of the second and first light-emitting portions 22a2 and intersects with the second and second light-emitting portions 22b2 only at a point X2. Furthermore, the direction in which the center O1 of the first light-emitting portion 22a1 points to the first intersection position X1 is opposite to the direction in which the center O2 of the second light-emitting portion 22a2 points to the second intersection position X2. Thus, it can be understood that the relative positional relationship between the first light-emitting portion 22a1 and the first and second light-emitting portions 22b1 differs from the relative positional relationship between the second light-emitting portion 22a2 and the second light-emitting portion 22b2. Figure 28 As shown in the example, the first and second light-emitting portions 22b1 surround the left side of the first light-emitting portion 22a1, and the second light-emitting portion 22b2 surrounds the right side of the second light-emitting portion 22a2. Alternatively, it can be understood that the azimuth angles corresponding to the first and second light-emitting portions 22b1 and the second light-emitting portion 22b2 are different. Figure 28As shown in the example, the azimuth angles corresponding to the first and second light-emitting portions 22b1 include an azimuth angle range of 180°-360°, while the azimuth angles corresponding to the second light-emitting portion 22b2 include an azimuth angle range of 0°-180°. In general, in the sharing mode, the wide-angle light compensated by the first and second light-emitting portions 22b1 for the first light-emitting portion 22a1 differs in azimuth angle from the wide-angle light compensated by the second light-emitting portion 22b2 for the second light-emitting portion 22a2.

[0106] Since the first and second light-emitting elements 221 and 222 are two adjacent light-emitting elements with the same light emission color, the first and second light-emitting portions 22b1 compensate for the first and second light-emitting portions 22a1 with a large viewing angle, and the second and second light-emitting portions 22b2 compensate for the second and first light-emitting portions 22a2 with a large viewing angle. When the first and second light-emitting elements 221 and 222 are displayed as a whole, the display effect can be that there is light emission with a large viewing angle at different azimuth angles, ensuring the overall large viewing angle display effect and large viewing angle display brightness of the second light-emitting elements 22 in the shared mode.

[0107] Further reference Figure 28 As shown, the display panel also includes a third virtual line V3 and a fourth virtual line V4 arranged in parallel. The third virtual line V3 passes through the center O1 of the first first light-emitting portion 22a1 and has two intersection points with the first second light-emitting portion. The fourth virtual line V4 passes through the center of the second first light-emitting portion 22a2 and has two intersection points with the second second light-emitting portion 22b2.

[0108] Continue to refer to Figure 28 As shown, a third virtual line V3 exists in the display panel. The extension direction of the third virtual line V3 intersects the extension direction of the first virtual line V1. The third virtual line V3 passes through the center O1 of the first light-emitting portion 22a1 and intersects with the first and second light-emitting portions 22b1 at two points, such as X3 and X4. That is, the first and second light-emitting portions 22b1 surround at least half of the area of ​​the first light-emitting portion 22a1, or in other words, the minimum azimuth angle range corresponding to the first and second light-emitting portions 22b1 is 180°.

[0109] The display panel also contains a fourth virtual line V4 parallel to the third virtual line V3. The extension direction of the fourth virtual line V4 intersects the extension direction of the second virtual line V2. The fourth virtual line V4 passes through the center O2 of the second first light-emitting portion 22a2 and intersects with the second second light-emitting portion 22b2 at two points, such as X5 and X6. That is, the second second light-emitting portion 22b2 surrounds at least half of the area of ​​the second first light-emitting portion 22a2, or in other words, the minimum azimuth angle range corresponding to the second second light-emitting portion 22b2 is 180°.

[0110] Thus, the splicing structure formed by joining the first and second light-emitting portions 22b1 and 22b2 together can form at least a complete ring structure that can completely surround the first light-emitting portion 22a. Alternatively, the splicing structure formed by joining the first and second light-emitting portions 22b1 and 22b2 has an azimuth range of 360°, allowing it to surround the first light-emitting portion 22a in all directions.

[0111] Since the first and second light-emitting elements 221 and 222 are two adjacent light-emitting elements with the same emission color, the first and second light-emitting portions 22b1 compensate for the first and second light-emitting portions 22a1 at a wide viewing angle of at least 180°, and the second and second light-emitting portions 22b2 compensate for the second and first light-emitting portions 22a2 at a wide viewing angle of at least 180°. When the first and second light-emitting elements 221 and 222 are displayed as a whole, the display effect can be that there is wide viewing angle light emission in the entire azimuth angle, or in other words, there is wide viewing angle light emission in the 360° omnidirectional angle. This fully ensures the overall wide viewing angle display effect and wide viewing angle display brightness of the second light-emitting elements 22 in the shared mode.

[0112] Based on the above embodiments, continue to refer to Figure 2 As shown, the display panel also includes a plurality of pixel circuits 5 located on one side of the substrate 1; the plurality of pixel circuits 5 include a first pixel circuit 51, a second pixel circuit 52 and a third pixel circuit 53, the first pixel circuit 51 is electrically connected to the first light-emitting element 21, the second pixel circuit 52 is electrically connected to the first light-emitting portion 22a, and the third pixel circuit 53 is electrically connected to the second light-emitting portion 22b; the first pixel circuit 51, the second pixel circuit 52 and the third pixel circuit 53 are independently arranged.

[0113] like Figure 1 and Figure 2 As shown, the display panel also includes a plurality of pixel circuits 5 and signal lines 6 located on one side of the substrate 1. The pixel circuits 5 may include transistors and capacitors. For example, the pixel circuits 5 may include at least two transistors and at least one capacitor. That is, the pixel circuits 5 may be a "2T1C" structure, a "6T2C" structure, a "7T1C" structure, or an "8T1C" structure. Here, "T" represents a transistor and "C" represents a capacitor. The specific structure of the pixel circuits 5 is not limited in this embodiment. Figure 2The pixel circuit is represented only by the transistors shown. The signal line 6 may include a scan signal line 61, a data signal line 62, and a power signal line (not shown in the figure). The pixel circuit 5 is electrically connected to the scan signal line 61, the data signal line 62, and the power signal line, respectively, and is used to convert the data signal provided by the data signal line 62 and the power signal provided by the power signal line into a driving current signal to drive the light-emitting element 2 to emit light, so as to achieve the purpose of driving the light-emitting element 2 to display light emission.

[0114] Furthermore, in the shared mode, the first light-emitting element 21, the first light-emitting portion 22a, and the second light-emitting portion 22b all emit light. In the privacy mode, the first light-emitting element 21 and the first light-emitting portion 22a both emit light, while the second light-emitting portion 22b does not emit light. This means that the light-emitting stages of different light-emitting elements or portions differ. Moreover, the brightness of different light-emitting elements or portions may vary. Therefore, the first pixel circuit 51 electrically connected to the first light-emitting element 21, the second pixel circuit 52 electrically connected to the first light-emitting portion 22a, and the third pixel circuit 53 electrically connected to the second light-emitting portion 22b are independently configured. The first pixel circuit 51, the second pixel circuit 52, and the third pixel circuit 53 independently control the light-emitting stages and brightness of the first light-emitting element 21, the first light-emitting portion 22a, and the second light-emitting portion 22b, ensuring that the light-emitting control logic of the first light-emitting element 21, the first light-emitting portion 22a, and the second light-emitting portion 22b is simple and efficient.

[0115] Based on the above embodiments, Figure 29 yes Figure 1 The diagram shows another cross-sectional structure of the display panel along section line A-A'. Figure 30 This is a schematic diagram illustrating the connection between the fourth pixel circuit and the first and second light-emitting portions according to an embodiment of this application. Figure 29 and Figure 30 As shown, the display panel also includes a plurality of pixel circuits 5 located on one side of the substrate 1; the plurality of pixel circuits 5 include a first pixel circuit 51 and a fourth pixel circuit 54, the first pixel circuit 51 being electrically connected to the first light-emitting element 21, and the fourth pixel circuit 54 being electrically connected to the first light-emitting portion 22a and the second light-emitting portion 22b respectively; the display panel also includes a switch unit 7 and a control module (not shown in the figure), the switch unit 7 being connected in series between the fourth pixel circuit 54 and the second light-emitting portion 22b, and the control module being electrically connected to the switch unit 7; the control module is used to control the switch unit 7 to conduct in the shared display mode, so as to conduct the fourth pixel circuit 54 and the second light-emitting portion 22b; the control module is also used to control the switch unit 7 to disconnect in the privacy mode, so as to disconnect the fourth pixel circuit 54 and the second light-emitting portion 22b.

[0116] Specifically, the pixel circuit 5 includes a first pixel circuit 51 and a fourth pixel circuit 54. The first pixel circuit 51 is electrically connected to the first light-emitting element 21 and is used to control the first light-emitting element 21 to emit light. The fourth pixel circuit 54 is electrically connected to the second light-emitting element 22 and is used to control the second light-emitting element 22 to emit light.

[0117] Furthermore, since the second light-emitting portion 22b surrounds at least part of the first light-emitting portion 22a to compensate for the light emitted from the first light-emitting portion 22a over a wide viewing angle, and the distance between the second light-emitting portion 22b and the first light-emitting portion 22a is small, the second light-emitting portion 22b and the first light-emitting portion 22a can share the fourth pixel circuit 54. This eliminates the need to add a pixel circuit 5 to the second light-emitting portion 22b, ensuring a simple arrangement of the pixel circuit 5 in the display panel. Moreover, since the first light-emitting portion 22a emits light while the second light-emitting portion 22b does not emit light in privacy mode, meaning there is a difference in the light emission stages of the first and second light-emitting portions 22a, a switching unit 7 can be provided between the fourth pixel circuit 54 and the second light-emitting portion 22b. Controlling the on and off states of the switching unit 7 allows for the control of the light emission of the first and second light-emitting portions 22a and 22b.

[0118] Specifically, the fourth pixel circuit 54 is electrically connected to the first light-emitting portion 22a and to the second light-emitting portion 22b via the switching unit 7. In shared mode, the control module controls the switching unit 7 to be turned on, and the fourth pixel circuit 54 controls both the first light-emitting portion 22a and the second light-emitting portion 22b to emit light, achieving normal light emission from the second light-emitting element 22 at both forward and wide viewing angles. In privacy mode, the control module controls the switching unit 7 to be turned off, and the fourth pixel circuit 54 controls the first light-emitting portion 22a to be turned off. At this time, the second light-emitting portion 22b does not emit light, achieving normal light emission from the second light-emitting element 22 at forward viewing angles and no light emission at wide viewing angles, thus realizing the privacy function.

[0119] Optional, Figure 31 yes Figure 1 The diagram shows another cross-sectional structure of the display panel along section line A-A', in conjunction with reference. Figure 2 and Figure 31 As shown, the display panel also includes a touch structure 81, a color resist structure, and a black light-shielding layer 82 located on the side of the light-emitting element 2 away from the substrate. The color resist structure includes color resist layers 83 of different colors. The light-shielding structure 3 includes at least one of the touch structure 81, at least two layers of color resist layers 83 of different colors stacked together, and a black light-shielding layer 82.

[0120] like Figure 2 and Figure 31As shown, the display panel also includes a touch structure 81 located on the side of the light-emitting element 2 away from the substrate. Users can perform touch operations on the display panel through the touch structure 81, enhancing the additional functions of the display panel. Furthermore, the touch structure 81 may include one or more touch function layers. Figure 2 and Figure 31 Taking the touch structure 81, which includes two layers of touch function layers, as an example, the corresponding touch structure 81 can be a touch structure in mutual capacitance mode. The touch structure in mutual capacitance mode can ensure that the touch operation of the touch structure 81 is sensitive and has high precision.

[0121] Furthermore, the display panel also includes a color resist structure located on the side of the light-emitting element 2 away from the substrate. The color resist structure can include color resist layers 83 of different colors. For example, a first-color light-emitting element can correspond to a first-color resist, thereby improving the color purity of the emitted light of the first color; a second-color light-emitting element can correspond to a second-color resist, thereby improving the color purity of the emitted light of the second color; and a third-color light-emitting element can correspond to a third-color resist, thereby improving the color purity of the emitted light of the third color. Moreover, by including the color resist structure in the display panel, interference light from the external environment can be filtered, reducing the interference of ambient light on the normal light emission of the display panel and ensuring the display effect of the display panel.

[0122] Furthermore, the display panel also includes a black light-shielding layer 82 located on the side of the light-emitting element 2 away from the substrate. This black light-shielding layer 82 blocks signal lines in the display panel, such as data signal lines or scan signal lines, to prevent them from becoming visible. Additionally, the inclusion of the black light-shielding layer 82 also filters out interfering light from the external environment, reducing interference from ambient light on the normal light emission of the display panel and ensuring its display performance.

[0123] Based on the above structure, the light-shielding structure 3 in the display panel may include at least one of the following: a touch structure 81, at least two layers of color resist layers 83 of different colors stacked together, and a black light-shielding layer 82. Figure 2 The explanation will take the light-shielding structure 3, which includes a black light-shielding layer 82, as an example. Figure 31 The following explanation uses an example where the light-shielding structure 3 includes at least two layers of color resist layers 83 of different colors. By setting the light-shielding structure 3 in the display panel to include at least one of the following: a touch structure 81, at least two layers of color resist layers 83 of different colors stacked together, and a black light-shielding layer 82, the setting method of the light-shielding structure 3 is kept simple, the existing structure in the display panel can be reused, and the film thickness of the display panel will not be increased, which is conducive to realizing a thin display panel design.

[0124] Based on the same inventive concept, this application also provides a display panel. Figure 32 yes Figure 1 The diagram shows another cross-sectional structure of the display panel along section line A-A', for reference. Figure 1 , Figure 32 as well as Figures 3 to 5 As shown, the display panel provided in this application embodiment includes a substrate 1 and a plurality of light-emitting elements 2 located on one side of the substrate; the plurality of light-emitting elements 2 include a first light-emitting element 21 and a second light-emitting element 22, the second light-emitting element 22 includes a first light-emitting portion 22a and a second light-emitting portion 22b, the second light-emitting portion 22b surrounding at least a portion of the first light-emitting portion 22a; the maximum light emission angle of the first light-emitting element 21 is greater than the maximum light emission angle of the first light-emitting portion 22a, and the minimum light emission angle of the second light-emitting portion 2b is greater than the minimum light emission angles of both the first light-emitting element 21 and the first light-emitting portion 22a; the display mode of the display panel includes a sharing mode and a privacy mode; in the sharing mode, the first light-emitting element 21, the first light-emitting portion 22a and the second light-emitting portion 22b all emit light; in the privacy mode, the first light-emitting element 21 and the first light-emitting portion 22a both emit light, and the second light-emitting portion 22b does not emit light.

[0125] Combination Figure 1 and Figure 32 As shown, the display panel includes a substrate 1 and a plurality of light-emitting elements 2 located on one side of the substrate 1. The light-emitting elements 2 may include light-emitting elements of different colors, such as at least one of red, green, blue, or white light-emitting elements. Furthermore, the light-emitting elements 2 may be one of organic light-emitting diodes (OLEDs), micro-OLEDs, or micro-LEDs. Taking an OLED as an example, the light-emitting element 2 may include a first electrode, a second electrode, and an organic compound layer located between the first and second electrodes. The organic compound layer may include a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, an electron transport layer, a hole blocking layer, and an electron injection layer, but is not limited thereto. Alternatively, the organic compound layer may also include a charge-generating layer, such as a P-type charge-generating layer and an N-type charge-generating layer. When a voltage is applied to the first and second electrodes of the OLED, holes passing through the hole transport layer and electrons passing through the electron transport layer move to the light-emitting layer to form excitons, causing visible light to be emitted from the light-emitting layer.

[0126] Further reference Figure 32As shown, the display panel also includes a pixel definition layer 4, which has multiple pixel openings that define the light-emitting area of ​​the light-emitting element. Specifically, the light-emitting element 2 includes a first light-emitting element 21 and a second light-emitting element 22. The second light-emitting element 22 includes a first light-emitting portion 22a and a second light-emitting element 22b, with the second light-emitting element 22b surrounding at least a portion of the first light-emitting portion 22a. Correspondingly, the pixel definition layer 4 includes a first pixel opening 41 and a second pixel opening 42, with the second pixel opening 42 including a first pixel opening portion 42a and a second pixel opening portion 42b, with the second pixel opening portion 42b surrounding at least a portion of the first pixel opening portion 42a. At least a portion of the first light-emitting element 21 is located within the first pixel opening 41, meaning at least a portion of the light-emitting film layer of the first light-emitting element 21 is located within the first pixel opening 41, and the first pixel opening 41 defines at least a portion of the light-emitting area of ​​the first light-emitting element 21. At least a portion of the first light-emitting portion 22a is located within the first pixel opening portion 42a, meaning at least a portion of the light-emitting film layer of the first light-emitting portion 22a is located within the first pixel opening portion 42a, and the first pixel opening portion 42a defines at least a portion of the light-emitting area of ​​the first light-emitting portion 22a. At least a portion of the second light-emitting portion 22b is located within the second pixel opening portion 42b, meaning at least a portion of the light-emitting film layer of the second light-emitting portion 22b is located within the second pixel opening portion 42b, and the second pixel opening portion 42b defines at least a portion of the light-emitting area of ​​the second light-emitting portion 22b. By setting the pixel definition layer 4 and the pixel opening, and defining at least a portion of the light-emitting film layer of the light-emitting element through the pixel opening, crosstalk between different light-emitting elements can be reduced, and the light emission contrast between different light-emitting elements can be improved.

[0127] Further reference Figure 32As shown, the display panel also includes a light-shielding structure 3 located on the light-emitting side of the light-emitting element 2. The light-shielding structure 3 is used to adjust the light emission angle of the light-emitting element 2. Specifically, the light-shielding structure 3 includes a first opening 31, a second opening 32, and a first light-shielding portion 33. Along a direction perpendicular to the plane of the substrate 1 (as shown in the Y direction), the first opening 31 at least partially overlaps with the first light-emitting element 21, so that at least a portion of the light generated by the first light-emitting element 21 can be emitted from the first opening 31; the second opening 32 at least partially overlaps with the first light-emitting portion 22a, so that at least a portion of the light generated by the first light-emitting portion 22a can be emitted from the second opening 32. In other words, at least the positive angle light or the narrow angle light of the first light-emitting element 21 can be emitted from the first opening 31, and the positive angle light or the narrow angle light of the first light-emitting portion 22a can be emitted from the second opening 32. The first light-blocking portion 33 and the second light-emitting portion 22b at least partially overlap. Thus, the frontal angle light, or narrow angle light, generated by the second light-emitting portion 22b is at least partially blocked by the first light-blocking portion 33 and cannot be emitted. The wide angle light generated by the second light-emitting portion 22b can at least partially be emitted from the second opening 32. That is, the minimum emission angle of the second light-emitting portion 2b is greater than the minimum emission angle of the first light-emitting element 21 and the first light-emitting portion 22a. Figure 32 As shown, the minimum light emission angle β1 of the second light-emitting portion 2b is greater than zero degrees, while the minimum light emission angles of the first light-emitting element 21 and the first light-emitting portion 22a are equal to zero degrees. Furthermore, along the direction parallel to the plane of substrate 1 (as shown in the X1 direction), the minimum distance d1 between the edge of the first opening 31 and the edge of the first pixel opening 41 and the minimum distance d2 between the edge of the second opening 32 and the edge of the first pixel opening portion 42a satisfy d1 > d2. That is, the distance between the edge of the first opening 31 and the edge of the first pixel opening 41 is relatively large, while the distance between the edge of the second opening 32 and the edge of the first pixel opening portion 42a is relatively small. Thus, light rays with a larger angle of emission from the first light-emitting element 21 can exit through the first opening 31 without being blocked by the light-shielding area outside the first opening 31, while light rays with a larger angle of emission from the first light-emitting portion 22a will be blocked by the light-shielding area outside the second opening 32 and cannot exit through the second opening 32. That is, after the light-shielding structure 3, the maximum light-emitting angle of the first light-emitting element 21 is greater than the maximum light-emitting angle of the first light-emitting portion 22a, such as Figure 32 As shown, the maximum light emission angle β2 of the first light-emitting element 21 is greater than the maximum light emission angle β3 of the first light-emitting portion 22a.

[0128] It is understood that the viewing angle in the embodiments of this application can be understood as the acute angle formed between the propagation direction of the light emitted by the light-emitting element and the thickness direction of the display panel. A narrow viewing angle, or small viewing angle, can be understood as a small angle between the direction of the light emitted by the light-emitting element and the thickness direction of the display panel, such as 0°, 5°, or 10°, or an acute angle less than 30°. A large viewing angle can be understood as a large angle between the direction of the light emitted by the light-emitting element and the thickness direction of the display panel, such as 50°, 60°, or 70°, or an acute angle greater than or equal to 45°. The narrow and large viewing angles in the embodiments of this application are relative concepts, and the embodiments of this application do not numerically limit the size of the viewing angle corresponding to a narrow or large viewing angle.

[0129] Specifically, the display panel has two display modes: a sharing mode and a privacy mode. In sharing mode, the first light-emitting element 21, the first light-emitting portion 22a, and the second light-emitting portion 22b all emit light. Thus, the light emitted by the first light-emitting element 21 is visible from both the direct viewing angle and the wide viewing angle, the light emitted by the first light-emitting portion 22a is visible from the direct viewing angle, and the light emitted by the second light-emitting portion 22b is visible from the wide viewing angle. In other words, the light emitted by both the first light-emitting element 21 and the second light-emitting element 22 is visible from both the direct viewing angle and the wide viewing angle, achieving normal display at different viewing angles. In privacy mode, both the first light-emitting element 21 and the first light-emitting portion 22a emit light, while the second light-emitting portion 22b does not emit light. Thus, the light emitted by the first light-emitting element 21 is visible from both the direct viewing angle and the wide viewing angle, and the light emitted by the first light-emitting portion 22a is visible from the direct viewing angle, ensuring that the display panel has normal display content and brightness from the direct viewing angle, achieving normal display. The light emitted from the second light-emitting portion 22b is invisible at wide viewing angles. This means that the light emitted from the second light-emitting element 22 is partially missing at wide viewing angles, causing color skipping due to this partial light loss. This results in blurred or disordered information displayed at wide viewing angles, thus achieving information confidentiality. In essence, privacy protection prevents information from being observed at wide viewing angles, preventing it from being seen or spied upon, thereby achieving visibility at narrow viewing angles but not at wide viewing angles.

[0130] Furthermore, the display panel includes multiple light-emitting element groups 20, each including at least one first light-emitting element 21 and at least one second light-emitting element 22. In shared mode, the light emitted by the first light-emitting element 21 and the second light-emitting element 22 within the same light-emitting element group 20 is visible at both normal and wide viewing angles, achieving normal display in shared mode. In privacy mode, at least one non-emitting second light-emitting portion 22b exists within the same light-emitting element group 20. This non-emitting second light-emitting portion 22b ensures that the second light-emitting portion 22b is missing from both the light-emitting element 20 and other light-emitting element groups that utilize it. This ensures that at least some light-emitting element groups will experience color skipping at wide viewing angles due to the absence of the second light-emitting portion 22b, resulting in blurred or disordered display information at wide viewing angles. This achieves confidentiality of the display information in at least some light-emitting element groups at wide viewing angles, thereby ensuring the confidentiality of the display information throughout the entire display panel and realizing the privacy function.

[0131] Furthermore, such as Figures 3 to 5 As shown, the light-emitting element group 20 may include a first-color light-emitting element 2R, a second-color light-emitting element 2B, and two third-color light-emitting elements 2G, that is, the light-emitting element group 20 can be an RGBG structure light-emitting element group. Thus, in at least a portion of the same light-emitting element group 20, there are one to three non-emitting second light-emitting portions 22b. These non-emitting second light-emitting portions 22b ensure that the light-emitting element 20 and other light-emitting element groups that utilize the second light-emitting portions 22b in this group all have their second light-emitting portions 22b absent, achieving privacy of the display information of at least a portion of the light-emitting element group in the wide viewing angle direction, thereby achieving privacy of the display information in the entire display panel and realizing a privacy protection function. Furthermore, as... Figures 3 to 5 As shown, in the same light-emitting element group 20, the first color light-emitting element 2R, the second color light-emitting element 2B, and the third color light-emitting element 2G can have a variety of different arrangements, and the embodiments of this application do not limit this.

[0132] In summary, the display panel provided in this application includes a first light-emitting element, a first light-emitting portion, and a second light-emitting portion. The maximum light-emitting angle of the first light-emitting element is greater than the maximum light-emitting angle of the first light-emitting portion, and the minimum light-emitting angle of the second light-emitting portion is greater than the minimum light-emitting angles of both the first light-emitting element and the first light-emitting portion. This ensures that the first light-emitting element emits light normally in both the forward and wide viewing angles, the first light-emitting portion emits light normally in the forward viewing angle, and the second light-emitting portion emits light normally in the wide viewing angle. Furthermore, by setting the light-emitting timing of the light-emitting element and the light-emitting portion in different display modes, the display panel can display normally at different viewing angles in the shared mode, while some content is missing in the privacy mode, thus achieving a privacy function. Moreover, by setting each light-emitting element group to include at least one first light-emitting element and at least one second light-emitting element, it is ensured that each light-emitting element group can achieve normal display in the shared mode, while at least some light-emitting element groups experience blurred or disordered information in the wide viewing angle in the privacy mode. This ensures the confidentiality of the display information in the wide viewing angle of at least some light-emitting element groups, thereby achieving the confidentiality of the display information in the entire display panel and realizing a privacy function.

[0133] Based on the above embodiments, continue to refer to Figure 1 , Figures 6 to 12 As shown, the display panel also includes a first color light-emitting element 2R, a second color light-emitting element 2B, and a third color light-emitting element 2G. The first color light-emitting element 2R, the second color light-emitting element 2B, and the third color light-emitting element 2G are all different from red, blue, and green light-emitting elements. The display panel also includes multiple light-emitting element columns CO arranged along a first direction (X2 direction as shown in the figure, hereinafter referred to as the first direction X2 in the explanation) and multiple light-emitting element rows RO arranged along a second direction (X3 direction as shown in the figure, hereinafter referred to as the second direction X3 in the explanation). The first direction X2 and the second direction X3 intersect. The i-th row of light-emitting elements RO... i Includes a first color light-emitting element 2R and a third color light-emitting element 2G arranged alternately along the first direction X2; the (i+1)th row of light-emitting elements RO i+1 Includes a second-color light-emitting element 2B and a third-color light-emitting element 2G arranged alternately along the first direction X2; the j-th column of light-emitting elements CO j Includes a first-color light-emitting element 2R and a third-color light-emitting element 2G arranged alternately along the second direction X3; and a (j+1)th column of light-emitting elements CO. j+1 It includes a second-color light-emitting element 2B and a third-color light-emitting element 2G arranged alternately along the second direction X3; where i and j are both positive integers.

[0134] Figure 1 , Figures 6 to 12Various arrangements of the first and second light-emitting elements of different colors are shown, such as... Figure 1 , Figures 6 to 12 As shown, the display panel includes multiple rows (RO) and columns (CO) of light-emitting elements; multiple light-emitting elements in the same row (RO) are arranged along a first direction X2, and multiple rows (RO) are arranged along a second direction X3; multiple light-emitting elements in the same column (CO) are arranged along the second direction X3, and multiple columns (CO) are arranged along the first direction X2. In two adjacent rows (RO) arranged along the second direction X3, the arrangement of light-emitting elements of different colors differs; for example, in the i-th row (RO)... i Including a first color light-emitting element 2R and a third color light-emitting element 2G arranged alternately along the first direction X2, and the (i+1)th row of light-emitting elements RO i+1 This includes second-color light-emitting elements 2B and third-color light-emitting elements 2G arranged alternately along the first direction X2. Furthermore, in two adjacent columns of light-emitting elements CO arranged along the first direction X2, the arrangement of light-emitting elements of different colors differs; for example, in the j-th column of light-emitting elements CO… j Includes a first-color light-emitting element 2R and a third-color light-emitting element 2G arranged alternately along the second direction X3; and a (j+1)th column of light-emitting elements CO. j+1 This includes a second-color light-emitting element 2B and a third-color light-emitting element 2G arranged alternately along the second direction X3. This ensures a uniform and regular arrangement of the first-color light-emitting element 2R, the second-color light-emitting element 2B, and the third-color light-emitting element 2G along the first direction X2 and the second direction X3. Furthermore, the first-color light-emitting element 2R, the second-color light-emitting element 2B, and the third-color light-emitting element 2G are all different from each other (red, blue, and green). This further ensures a uniform and regular arrangement of different colors of light-emitting elements along the first direction X2 and the second direction X3, guaranteeing better display rendering effects between different colors and further ensuring the color display effect of the display panel. Simultaneously, the distribution density of the third-color light-emitting element 2G is greater than that of the first-color light-emitting elements 2R and the second-color light-emitting elements 2B. The third-color light-emitting element 2G can be a green light-emitting element. This arrangement aligns with the physiological characteristic that the human eye is most sensitive to green light, ensuring that a higher visual clarity display effect can be achieved with lower power consumption.

[0135] It should be noted that the light-emitting element rows and columns in the embodiments of this application can be understood as collections of light-emitting elements formed by multiple light-emitting elements arranged along a specific direction. For example, a collection of light-emitting elements formed by multiple light-emitting elements arranged along the first direction X2 can be a light-emitting element row, and a collection of light-emitting elements formed by multiple light-emitting elements arranged along the second direction X3 can be a light-emitting element column. In subsequent embodiments, a collection of light-emitting elements formed by multiple light-emitting elements arranged along a third direction (X4 direction as shown in the figure, which will be used as an example in the following description) can also be a light-emitting element row, and a collection of light-emitting elements formed by multiple light-emitting elements arranged along a fourth direction (X5 direction as shown in the figure, which will be used as an example in the following description) can also be a light-emitting element column. The arrangement direction of multiple light-emitting elements in a light-emitting element row is not unique, and the arrangement direction of multiple light-emitting elements in a light-emitting element column is not unique.

[0136] Based on the above embodiments, continue to refer to Figure 1 , Figures 6 to 12 As shown, the first color light-emitting element 2R includes a first color first light-emitting element 21R and a first color second light-emitting element 22R; the second color light-emitting element 2B includes a second color first light-emitting element 21B and a second color second light-emitting element 22B; the third color light-emitting element 2G includes a third color first light-emitting element 21G and a third color second light-emitting element 22G; the first light-emitting element 21 includes a first color first light-emitting element 21R, a second color first light-emitting element 21B, and a third color first light-emitting element 21G; the second light-emitting element 22 includes a first color second light-emitting element 22R, a second color second light-emitting element 22B, and a third color second light-emitting element 22G; the display panel also includes a plurality of light-emitting element columns CO arranged along a third direction X4 and a plurality of light-emitting element rows RO arranged along a fourth direction X5; wherein, the third direction X4 intersects with the first direction X2, the second direction X3, and the fourth direction X5, and the fourth direction X5 intersects with the first direction X2 and the second direction X3; wherein, in the same light-emitting element row, the first light-emitting elements 21 and the second light-emitting elements 22 of the same color are alternately arranged along the third direction X4.

[0137] like Figure 1 , Figures 6 to 12As shown in the embodiment of this application, the first light-emitting element 21 includes a first-color first light-emitting element 21R, a second-color first light-emitting element 21B, and a third-color first light-emitting element 21G. The second light-emitting element 22 includes a first-color second light-emitting element 22R, a second-color second light-emitting element 22B, and a third-color second light-emitting element 22G. That is, both the first light-emitting element 21 and the second light-emitting element 22 include multiple light-emitting elements of different colors. Thus, in the sharing mode, the first-color first light-emitting element 21R, the second-color first light-emitting element 21B, the third-color first light-emitting element 21G, the first-color second light-emitting element 22R, the second-color second light-emitting element 22B, and the third-color second light-emitting element 22G all emit light, achieving color display with both a positive viewing angle and a wide viewing angle in the sharing mode. In the privacy mode, the first-color first light-emitting element 21R, the second-color first light-emitting element 21B, the third-color first light-emitting element 21G, the first-color second light-emitting element 21R, the second-color second light-emitting element 21B, and the third-color second light-emitting element 22G all emit light, achieving color display with both a positive viewing angle and a wide viewing angle in the sharing mode. The first light-emitting portion 22a of the first light-emitting element 22R, the first light-emitting portion 22a of the second light-emitting element 22B, and the first light-emitting portion 22a of the third light-emitting element 22G emit light normally, realizing a positive viewing angle color display in the privacy mode; and the second light-emitting portion 22b of the first light-emitting element 22R, the second light-emitting portion 22b of the second light-emitting element 22B, and the second light-emitting portion 22b of the third light-emitting element 22G do not emit light, realizing the absence of the large viewing angle light-emitting portion in the privacy mode, causing at least some light-emitting element groups to have blurred or disordered large viewing angle display information in the privacy mode, thus achieving the privacy function by keeping the display information of at least some light-emitting element groups confidential in the large viewing angle direction.

[0138] Furthermore, within the same row RO of light-emitting elements, the first light-emitting element 21 and the second light-emitting element 22 of the same color are arranged alternately along the third direction X4. That is, the first light-emitting element 21R and the second light-emitting element 22R of the first color are arranged alternately in the third direction X4, and / or, the first light-emitting element 21B and the second light-emitting element 22B of the second color are arranged alternately in the third direction X4, and / or, the first light-emitting element 21G and the second light-emitting element 22G of the third color are arranged alternately in the third direction X4. In this way, the first light-emitting element 21, which includes light emission from a wide viewing angle, and the second light-emitting element 22R, which does not include light emission from a wide viewing angle, are evenly distributed in the third direction X4, which can ensure that the display panel has a uniform brightness in the third direction X4. To avoid the situation where the first light-emitting element 21, which contains a wide-viewing-angle light emission, is densely packed in the third direction X4, resulting in a large display brightness in this area, and the second light-emitting element 22, which does not contain a wide-viewing-angle light emission, is densely packed in the third direction X4, resulting in a small display brightness in this area, this method avoids uneven brightness display areas on the light-emitting display panel in the third direction X4, thus ensuring good uniformity of display brightness on the display panel.

[0139] Optional, continue to refer to Figure 1 , Figures 6 to 12 As shown, in the same light-emitting element column CO, the first group GR1 and the second group GR2 are arranged alternately along the fourth direction X5; wherein, the first group GR1 includes two first light-emitting elements 21 of the same color, and the second group GR2 includes two second light-emitting elements 22 of the same color.

[0140] like Figure 1 , Figures 6 to 12 As shown, the same light-emitting element column CO includes multiple groups GR. A group GR can be understood as a set of light-emitting elements formed by arranging two light-emitting elements 2 of the same color in the fourth direction X5. Furthermore, two groups GR arranged adjacent to each other in the fourth direction X5 include a first group GR1 and a second group GR2. The light-emitting elements contained in the first group GR1 and the second group GR2 have the same emission color, and the first group GR1 includes two first light-emitting elements 21, and the second group GR2 includes two second light-emitting elements 22. Thus, in the same light-emitting element column CO formed by multiple light-emitting elements 2 arranged along the fourth direction X5, the first light-emitting elements 21 and the second light-emitting elements 22 of the same color are arranged alternately in pairs along the fourth direction X5. That is, the first group GR1 containing two first light-emitting elements 21R of the first color and the second group GR2 containing two first light-emitting elements 22R of the first color are arranged alternately in the fourth direction X5; and / or, the first group GR1 containing two first light-emitting elements 21B of the second color and the second group GR2 containing two second light-emitting elements 22B of the second color are arranged alternately in the fourth direction X5; and / or, the first group GR1 containing two first light-emitting elements 21G of the third color and the second group GR2 containing two second light-emitting elements 22G of the third color are arranged alternately in the fourth direction X5. In this way, the first group GR1 containing the first light-emitting elements 21 with a wide viewing angle and the second group GR2 without the second light-emitting elements 22R with a wide viewing angle are evenly distributed in the fourth direction X5, which can ensure that the display panel has a uniform brightness in the fourth direction X5. To avoid the situation where the first group of GR1, which contains the first light-emitting element 21 with a wide viewing angle, is densely packed in the fourth direction X5, resulting in a large display brightness in this area, and the second group of GR2, which does not contain the second light-emitting element 22 with a wide viewing angle, is densely packed in the fourth direction X5, resulting in a small display brightness in this area, this method avoids uneven brightness display areas on the light-emitting display panel in the fourth direction X5, thus ensuring good uniformity of display brightness on the display panel.
