Description

Display panel and display device

[0001] This invention claims priority to Chinese Patent Application No. 202411448983.5, filed with the State Intellectual Property Office of China on October 16, 2024, entitled “Display Panel and Display Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display technology, and more specifically to a display panel and display device. Background Technology

[0003] With the continuous development of display technology, consumers' demands for displays are constantly increasing. Currently, various types of displays, including LCD screens and OLED screens, are emerging in large numbers and have developed rapidly. Based on this, display technologies such as 3D display, touch display technology, curved display, ultra-high resolution display, and privacy-protected display are constantly emerging.

[0004] Currently, researchers are paying close attention to improving the privacy protection performance of active-matrix displays, including organic light-emitting diodes (OLEDs). Summary of the Invention

[0005] In view of this, this application provides a display panel and a display device to improve the privacy protection effect of the display panel.

[0006] In a first aspect, embodiments of this application provide a display panel, including:

[0007] Substrate;

[0008] A light-emitting element located on one side of the substrate;

[0009] The first dimming interface protrudes in a direction away from the substrate, and is offset from the light-emitting element in a direction perpendicular to the plane of the substrate.

[0010] The second dimming interface is recessed towards the substrate, and is offset from the light-emitting element along a direction perpendicular to the plane of the substrate.

[0011] Along a direction perpendicular to the plane of the substrate, the first dimming interface and the second dimming interface are offset from each other.

[0012] Secondly, embodiments of this application provide a display device, including the display panel described above.

[0013] The display panel and display device provided in this invention, by setting a first dimming interface and a second dimming interface in the display panel, with the first dimming interface protruding away from the substrate and the second dimming interface recessed towards the substrate, can adjust the propagation direction of large-angle light emitted by the light-emitting element using the first and second dimming interfaces. The adjusted light can exit the display panel at a small angle, thereby preventing the light emitted by the light-emitting element from exiting the display panel at a large exit angle. This prevents users at a large viewing angle from seeing or clearly seeing the display screen, achieving a large-viewing-angle privacy protection effect. Moreover, based on this setting, the first and second dimming interfaces can also be used to adjust the original large-angle light to a small-angle light emitted from the display panel, improving the light utilization rate of the light-emitting element, increasing the brightness of the display panel at a normal viewing angle, and reducing the power consumption of the display panel while ensuring the display brightness at a normal viewing angle.

[0014] When the display panel is used in a vehicle display, the first and second dimming interfaces can narrow the large-angle light emitted by the vehicle display, such as light directed toward the windshield. For example, it can be adjusted to parallel light, improving the problem of windshield reflection and achieving privacy protection. Attached Figure Description

[0029] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0031] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0032] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0033] Currently, flexible automotive displays typically use a privacy film attached to the module cover. The principle behind this film is to reduce the distance between the slats of a louvered screen in a systematic way, creating an ultra-fine louver layer. This ensures that light from the front of the screen is only blocked by the narrowest area of ​​the slats, maximizing light transmittance and visibility for the human eye. As the viewing angle increases, the area blocked by the slats increases, and the visible light transmittance decreases, causing the screen to gradually darken. When the angle is tilted to a certain degree, the screen becomes so dark that no content is visible to the human eye, thus protecting the privacy of the screen content. However, this method increases the cost and thickness of the display device, which is not conducive to thin and light displays.

[0034] In view of this, the present invention provides a display panel, as shown in Figures 1 and 2. Figure 1 is a schematic diagram of a display panel provided by the present invention, and Figure 2 is a cross-sectional schematic diagram of Figure 1 along AA'. The display panel includes a substrate 1, a light-emitting element 2, a first dimming interface 31, and a second dimming interface 32.

[0035] As shown in Figure 2, the light-emitting element 2 is located on one side of the substrate 1. The first dimming interface 31 protrudes in a direction away from the substrate 1, and is offset from the light-emitting element 2 along a direction perpendicular to the plane of the substrate 1. The second dimming interface 32 is recessed in a direction closer to the substrate 1, and is offset from the light-emitting element 2 along a direction perpendicular to the plane of the substrate 1.

[0036] When the display panel is operating, the light-emitting element 2 emits light with various emission angles. For the large-angle light emitted by the light-emitting element 2, this refers to light whose propagation direction forms an angle greater than a first preset angle with the normal to the substrate. This portion of light can be adjusted by the first dimming interface 31 and the second dimming interface 32 to emit small-angle light from the display panel. Conversely, small-angle light refers to light whose propagation direction forms an angle less than the first preset angle with the normal to the substrate. The first preset angle can be set according to the viewing angle privacy requirements of the display panel; for example, in this embodiment, the first preset angle can be 45° or 60°.

[0037] Specifically, as shown by ray L11 in Figure 2, ray L11 is reflected after hitting the first dimming interface 31, and the reflected ray can exit from the display panel at a smaller exit angle than ray L11. Here, the exit angle refers to the angle between the direction of ray propagation and the normal to the substrate 1. Similarly, as shown by ray L12 in Figure 2, ray L12 is refracted after hitting the first dimming interface 31, and the refracted ray can also exit from the display panel at a smaller exit angle than ray L12.

[0038] As shown by ray L21 in Figure 2, ray L21 represents the light emitted by the light-emitting element 2 that is reflected by other film layers inside the display panel and strikes the second dimming interface 32. After refraction by the second dimming interface 32, this light can exit at a smaller exit angle. Similarly, as shown by ray L22 in Figure 2, ray L22 represents the large-angle light emitted by the light-emitting element 2 that directly strikes the second dimming interface 32. After refraction by the second dimming interface 32, this light can exit at a smaller exit angle.

[0039] As can be seen, based on the above-described configuration provided in this embodiment of the invention, the emitted light from the light-emitting element 2 can be prevented from exiting the display panel at a large angle, thereby preventing users at wide viewing angles from seeing or clearly viewing the display screen, achieving a wide-viewing-angle privacy protection effect. Furthermore, based on this configuration, the first dimming interface 31 and the second dimming interface 32 can be used to adjust the original large-angle light to a small-angle light emitted from the display panel, improving the light utilization rate of the light-emitting element 2, increasing the brightness of the display panel at a normal viewing angle, and reducing the power consumption of the display panel while ensuring the display brightness at a normal viewing angle.

[0040] When the display panel is used in a vehicle display, the first dimming interface 31 and the second dimming interface 32 can narrow the large-angle light emitted by the vehicle display, such as light directed toward the windshield. For example, it can be adjusted to parallel light to improve the problem of windshield reflection and achieve privacy protection.

[0041] For example, as shown in Figures 1 and 2, the first dimming interface 31 and the second dimming interface 32 are both offset from the light-emitting element 2 along a direction perpendicular to the plane of the substrate 1, and they are also offset from each other. This avoids the first dimming interface 31 and the second dimming interface 32 adjusting the small-angle light emitted by the light-emitting element 2, thus ensuring the display effect of the display panel at a normal viewing angle. Moreover, by making the first dimming interface 31 and the second dimming interface 32 offset from each other in a direction perpendicular to the plane of the substrate 1, this embodiment of the invention can adjust various large-angle light emitted by the light-emitting element 2.

[0042] Furthermore, as shown in Figure 2, the display panel also includes an array layer 30, which includes metal traces (not shown in Figure 2) and a pixel driving circuit (not shown in Figure 2) electrically connected to the light-emitting element 2. The pixel driving circuit includes thin-film transistors. For example, for light emitted by the light-emitting element 2 propagating towards the substrate 1, the metal traces can reflect this portion of the light. The reflected light can then be directed towards the second dimming interface 32 and, after dimming by the second dimming interface 32, exit the display panel at a smaller exit angle, thereby further improving the privacy protection effect at wide viewing angles and increasing the brightness of the display panel at a normal viewing angle. Moreover, based on this arrangement, light can be prevented from hitting the thin-film transistors, thus preventing changes in the characteristics of the thin-film transistors due to illumination and ensuring reliable electrical performance of the thin-film transistors.

[0043] For example, as shown in FIG2, at least a portion of the first dimming interface 31 is located on the light-emitting side of the light-emitting element 2. That is, along the direction perpendicular to the plane of the substrate 1, at least a portion of the first dimming interface 31 is located on the side of the light-emitting element 2 away from the substrate 1. Based on this arrangement, at least a portion of the large-angle light emitted by the light-emitting element 2 that propagates towards the side away from the substrate 1 can be directed toward the first dimming interface 31, and the first dimming interface 31 can adjust the propagation direction of this portion of large-angle light so that this portion of light is emitted from the first dimming interface 31 at a smaller emission angle.

[0044] For example, as shown in FIG1, in this embodiment of the invention, the first dimming interface 31 and the second dimming interface 32 can be located between two adjacent light-emitting elements 2. Based on this arrangement, the distance between the first dimming interface 31 and the second dimming interface 32 can be reduced, so that at least a portion of the large-angle light emitted by the same light-emitting element 2 can pass through the adjustment of the first dimming interface 31 and the second dimming interface 32 in sequence, further reducing the emission angle of the emitted light.

[0045] For example, as shown in Figures 1 and 2, in this embodiment of the invention, the second dimming interface 32 can be located on the side of the first dimming interface 31 away from the light-emitting element 2. At least two first dimming interfaces 31 and at least one second dimming interface 32 are included between two adjacent light-emitting elements 2, and the second dimming interface 32 is located between two adjacent first dimming interfaces 31 along a direction parallel to the plane of the substrate 1. Based on this arrangement, at least a portion of the light emitted through the second dimming interface 32 can continue to be directed towards the first dimming interfaces 31 located on both sides of it, thereby allowing this portion of light to further reduce its emission angle through the action of the first dimming interfaces 31.

[0046] For example, as shown in FIG2, at least a portion of the second dimming interface 32 is located on the side of the light-emitting element 2 closer to the substrate 1. Based on this arrangement, at least a portion of the large-angle light emitted by the light-emitting element 2 that propagates towards the side closer to the substrate 1 can be directed toward the second dimming interface 32, and the second dimming interface 32 can adjust the propagation direction of this portion of large-angle light so that this portion of light is emitted from the second dimming interface 32 at a smaller exit angle.

[0047] For example, as shown in FIG2, the display panel further includes a pixel definition layer 4 and a protrusion 5. The pixel definition layer 4 includes a first opening 41, and the light-emitting element 2 includes a light-emitting layer 20, at least a portion of which is located within the first opening 41. The protrusion 5 protrudes from the surface of the pixel definition layer 4 toward a side away from the substrate 1; the protrusion 5 includes a first surface S11 on the side away from the substrate 1; the first dimming interface 31 includes the first surface S11. That is, when the light emitted by the light-emitting element 2 strikes the first surface S11, the exit angle of the light emitted through the first surface S11 can be reduced, thereby reducing the brightness of the display panel at a wide viewing angle and achieving a wide-viewing-angle privacy protection effect.

[0048] Optionally, as shown in Figure 2, the pixel definition layer 4 further includes a second opening 42; at least a portion of the second dimming interface 32 includes a sidewall S42 of the second opening 42. That is, after the light emitted by the light-emitting element 2 strikes the sidewall S42, the exit angle of the light emitted through the sidewall S42 can be reduced, thereby reducing the brightness of the display panel at a wide viewing angle and achieving a wide-viewing-angle privacy protection effect.

[0049] For example, the second opening 42 and the third opening 43 can be formed in the same patterning process. The protrusion 5 can be formed before or after the second opening 42 is formed.

[0050] For example, the material of the protrusion 5 may be different from or the same as the material of the pixel definition layer 4. This embodiment of the invention does not limit this.

[0051] For example, as shown in FIG2, the protrusion 5 includes a first bottom surface S21 close to the substrate 1; the second opening 42 includes a first top surface S31 away from the substrate 1, wherein the first top surface S31 can be understood as the part of the sidewall S42 forming the second opening 42 that is furthest from the substrate 1. As shown in FIG2, the first bottom surface S21 and the first top surface S31 are on the same horizontal plane, which is parallel to the plane where the substrate 1 is located. FIG2 illustrates this horizontal plane with dashed lines. This horizontal plane can serve as the boundary between the first dimming interface 31 and the second dimming interface 32, that is, along the direction perpendicular to the plane where the substrate 1 is located, the first dimming interface 31 and the second dimming interface 32 are respectively located on both sides of this horizontal plane.

[0052] For example, as shown in Figure 2, this horizontal plane can be regarded as the surface S40 of the pixel definition layer 4.

[0053] For example, as shown in Figures 1 and 3, Figure 3 is a cross-sectional schematic diagram along BB' of Figure 1. The display panel also includes a support portion 6, which protrudes from the surface S40 of the pixel definition layer 4 toward the side away from the substrate 1. The support portion 6 is used to support the mask in the vapor deposition process to ensure vapor deposition uniformity and improve vapor deposition yield.

[0054] As shown in Figure 3, the support portion 6 includes a second surface S12 on the side away from the substrate 1; the distance between the second surface S12 and the light-emitting element 2 along the direction perpendicular to the plane of the substrate 1 is h2. As shown in Figure 2, the distance between the first surface S11 and the light-emitting element 2 along the direction perpendicular to the plane of the substrate 1 is h1. Wherein, 0 < h1 < h2 ≤ 3 μm. Based on this arrangement, when using the support portion 6 to support the mask, contact between the mask and the protrusion 5 can be avoided, thus preventing scratches and other abnormalities on the protrusion 5, improving the structural reliability of the protrusion 5, and allowing the protrusion 5 to be used to adjust the large-angle light emitted by the light-emitting element 2.

[0055] For example, in this embodiment of the invention, the bottom surface of the support portion 6 near the substrate 1 and the bottom surface of the protrusion 5 near the substrate 1 can be on the same horizontal plane, and the height of the protrusion 5 can be less than the height of the support portion 6, so as to avoid the mask from contacting the protrusion 5 when the support portion 6 is used to support the mask.

[0056] For example, as shown in Figure 2, the first surface S11 intersects the surface S40 of the pixel definition layer 4 at a first intersection line A1, and the angle between the tangent of the first surface S11 at the first intersection line A1 and the plane containing the substrate 1 is θ1. As shown in Figure 3, the second surface S12 intersects the surface of the pixel definition layer 4 at a second intersection line A2, and the angle between the tangent of the second surface S12 at the second intersection line A2 and the plane containing the substrate 1 is θ2, where 45°≤θ1≤θ2≤90°.

[0057] Based on this configuration, on the one hand, the angle between the tangent of the first surface S11 at the first intersection line A1 and the plane of the substrate 1 can be smaller, that is, the tilt of the first surface S11 relative to the plane of the substrate 1 is weaker. This is beneficial for the first surface S11 to receive more large-angle light emitted by the light-emitting element 2 and to adjust more large-angle light to be emitted at a smaller angle, further improving the privacy protection effect of the display panel from a wide viewing angle. On the other hand, by making the angle between the tangent of the second surface S12 at the second intersection line A2 and the plane of the substrate 1 larger, the tilt of the second surface S12 relative to the plane of the substrate 1 can be made larger. While ensuring that the height of the support part 6 reaches the height required to support the mask, it is possible to avoid setting the area of ​​the support part 6 to be too large. This is beneficial for using more space in the display panel to set the light-emitting element 2, that is, to increase the area of ​​the light-emitting element 2 and improve the aperture ratio.

[0058] Optionally, as shown in Figure 1, along a direction parallel to the plane of the substrate 1, the distance between the protrusion 5 and the nearest light-emitting element 2 is L1, and the distance between the support 6 and the nearest light-emitting element 2 is L2, where L1 ≤ L2. Based on this arrangement, the distance between the protrusion 5 and the light-emitting element 2 can be made closer, allowing the first surface S11 of the protrusion 5 to receive more large-angle light emitted by the light-emitting element 2 and convert more large-angle light into small-angle light for emission, which helps to reduce the intensity of large-angle light and improve the privacy protection effect.

[0059] For example, as shown in FIG2, the width of the protrusion 5 gradually decreases along the direction away from the substrate 1. The light emitted by the light-emitting element 2 can be reflected when it strikes the first surface S11. By making the width of the protrusion 5 gradually decrease along the direction away from the substrate 1, this embodiment of the invention allows the light reflected by the first surface S11 to be emitted towards the light-emitting side of the display panel, which is beneficial to improving the brightness of the display panel. Furthermore, based on this arrangement, when other film layers are subsequently formed above the protrusion 5, it is possible to avoid the film layers formed above the protrusion 5 from breaking at the location of the protrusion 5. For example, when the cathode of the light-emitting element 2 is disposed above the protrusion 5, this arrangement can prevent the cathode from breaking at the protrusion 5, which is beneficial to improving the connection reliability of the cathode.

[0060] For example, as shown in FIG2, the width of the second opening 42 gradually decreases along the direction close to the substrate 1. Based on this arrangement, when other film layers are subsequently formed above the second opening 42, it is possible to avoid the film layers formed above the second opening 42 from being broken at the location of the second opening 42. For example, when the cathode of the light-emitting element 2 is disposed above the second opening 42, based on this arrangement, it is possible to avoid the cathode being broken at the second opening 42, which is beneficial to improving the connection reliability of the cathode.

[0061] For example, as shown in FIG2, in an embodiment of the present invention, the side of the first dimming interface 31 away from the substrate 1 may include a curved surface. FIG2 illustrates the cross-sectional shape of the first dimming interface 31 as an arc. Alternatively, in an embodiment of the present invention, the side of the first dimming interface 31 away from the substrate 1 may also include a plane. As shown in FIG4 and FIG5, FIG4 and FIG5 are schematic diagrams of two other cross-sections along AA' of FIG1. ​​In FIG4, the cross-sectional shape of the first dimming interface 31 is trapezoidal. In FIG5, the cross-sectional shape of the first dimming interface 31 is triangular.

[0062] Optionally, in embodiments of the present invention, the side of the second dimming interface 32 near the substrate 1 may include a planar or curved surface.

[0063] For example, as shown in FIG6, which is another cross-sectional view of FIG1 along AA', the display panel further includes a first film layer 71 covering the protrusion 5. The first film layer 71 and the protrusion 5 are in contact, and the aforementioned first surface S11 is the contact surface between them. In this embodiment of the invention, the refractive index of the first film layer 71 is less than the refractive index of the protrusion 5.

[0064] When the light-emitting element 2 is lit, as shown in Figure 6, the large-angle light emitted by the light-emitting element 2 can illuminate the interface between the protrusion 5 and the first film layer 71, that is, the aforementioned first surface S11. In this embodiment of the invention, by making the refractive index of the first film layer 71 less than that of the protrusion 5, when the light passes from the inside of the protrusion 5 through the first surface S11 and shines on the first film layer 71, according to the law of refraction, the propagation direction of the light passing through the first surface S11 can be deflected towards the normal direction closer to the substrate 1. That is, the first surface S11 can adjust the large-angle light to a small-angle light, thereby increasing the brightness at the normal viewing angle and reducing the intensity of the large-angle light, thus achieving a large-view anti-spy effect.

[0065] For example, as shown in FIG6, the light-emitting element 2 includes a first electrode 21, a light-emitting layer 20, a common layer 23, and a second electrode 22 stacked along a direction perpendicular to the plane of the substrate 1. In this embodiment of the invention, the first film layer 71 includes the common layer 23. Optionally, the common layer 23 includes a first sub-common layer 231 and / or a second sub-common layer 232. At least a portion of the first sub-common layer 231 is located between the first electrode 21 and the light-emitting layer 20, and at least a portion of the second sub-common layer 232 is located between the second electrode 22 and the light-emitting layer 20. Optionally, the first electrode 21 includes an anode, and the second electrode 22 includes a cathode. The first sub-common layer 231 includes a hole injection layer and / or a hole transport layer. At least a portion of the second sub-common layer 232 includes an electron injection layer and / or an electron transport layer.

[0066] Optionally, as shown in FIG6, the display panel further includes a second film layer 72 at least partially located within the second opening 42. The second film layer 72 is in contact with the sidewall S42 of the second opening 42, and the portion of the second dimming interface 32 is the contact surface between the second film layer 72 and the sidewall S42 of the second opening 42. In this embodiment of the invention, the refractive index of the second film layer 72 is greater than the refractive index of the pixel definition layer 4. Based on this setting, according to the law of refraction, large-angle light rays from the pixel definition layer 4 passing through the second dimming interface 32 and directed to the second film layer 72 can be adjusted into small-angle light rays.

[0067] For example, as shown in Figure 7, which is another cross-sectional view of Figure 1 along AA', the display panel further includes a planarization layer 8 located on the side of the pixel definition layer 4 near the substrate 1. The planarization layer 8 includes a third opening 43, which overlaps at least partially with the second opening 42 along a direction perpendicular to the plane of the substrate 1. At least a portion of the second dimming interface 32 includes the sidewall S43 of the third opening 43. The third opening 43 increases the area of ​​the second dimming interface 32 based on the second opening 42, thereby allowing the second dimming interface 32 to receive more large-angle light emitted by the light-emitting element 2 and adjust the large-angle light emitted by the light-emitting element 2, preventing more large-angle light from escaping from the display panel, thus further improving the wide-viewing angle privacy protection effect of the display panel.

[0068] For example, as shown in FIG7, at least a portion of the second film layer 72 is located within the third opening 43. The second film layer 72 is in contact with the sidewalls S42 of the second opening 42 and S43 of the third opening 43, respectively. A portion of the second dimming interface 32 is the contact surface between the second film layer 72 and the sidewall S42 of the second opening 42, and the other portion is the contact surface between the second film layer 72 and the sidewall S43 of the third opening 43. In this embodiment of the invention, the refractive index of the second film layer 72 is greater than the refractive index of the planarization layer 8. Based on this arrangement, according to the law of refraction, large-angle light rays incident from the planarization layer 8 through the second dimming interface 32 onto the second film layer 72 can be adjusted into small-angle light rays.

[0069] It should be noted that the arrangement of the third opening 43 penetrating the planarization layer 8 shown in Figure 7 is only for illustration. In this embodiment of the invention, the depth of the third opening 43 may be less than the thickness of the planarization layer 8, that is, the third opening 43 may not penetrate the planarization layer 8.

[0070] For example, as shown in FIG7, the light-emitting element 2 includes a first electrode 21, a light-emitting layer 20, a common layer 23, and a second electrode 22 stacked along a direction perpendicular to the plane of the substrate 1, and the second film layer 72 includes the aforementioned common layer 23. Optionally, the common layer 23 includes a first sub-common layer 231 and / or a second sub-common layer 232. At least a portion of the first sub-common layer 231 is located between the first electrode 21 and the light-emitting layer 20, and at least a portion of the second sub-common layer 232 is located between the second electrode 22 and the light-emitting layer 20. Optionally, the first electrode 21 includes an anode, and the second electrode 22 includes a cathode. The first sub-common layer 231 includes a hole injection layer and / or a hole transport layer. At least a portion of the second sub-common layer 232 includes an electron injection layer and / or an electron transport layer.

[0071] For example, the second film layer 72 can be formed in the same process using the same material as the first film layer 71, and the two can be two parts of the same film layer in different regions. That is, there may be no dividing line between them.

[0072] In this case, the refractive index of the protrusion 5 is different from that of the pixel definition layer 4, and the two can be formed using different materials.

[0073] As shown in Figures 6 and 7, based on the morphological characteristics of the protrusion 5, the path of lateral leakage current through the common layer 23 between two adjacent light-emitting elements 2 can be extended, thereby suppressing the transmission of lateral leakage current, preventing the light-emitting elements 2 that should not be lit from lighting up, and improving the display effect.

[0074] Furthermore, the common layer 23, which is formed after the second opening 42, is formed on the side wall S42 of the second opening 42. Based on the morphological characteristics of the second opening 42, the path of lateral leakage current through the common layer 23 between two adjacent light-emitting elements 2 can be extended, thereby suppressing the transmission of lateral leakage current and improving the display effect.

[0075] For example, as shown in FIG1, the orthographic projection shape of the first dimming interface 31 and the second dimming interface 32 on the plane of the substrate 1 can be a strip structure. As shown in FIG1, the lengths of the first dimming interface 31 and the second dimming interface 32 in the first direction h1 are respectively greater than the lengths in the second direction h2.

[0076] Alternatively, in this embodiment of the invention, the orthographic projection shape of at least one of the first dimming interface 31 and the second dimming interface 32 onto the plane of the substrate 1 can be set as a block structure.

[0077] For example, as shown in FIG8, FIG8 is a top view of a display panel provided in an embodiment of the present invention. The display panel includes a plurality of first dimming interfaces 31 and second dimming interfaces 32 disposed corresponding to light-emitting elements 2. The shape of the orthographic projection of the first dimming interface 31 onto the plane where the substrate 1 is located is a block structure with approximately equal lengths in the first direction h1 and the second direction h2. FIG8 illustrates that the shape of the orthographic projection of the first dimming interface 31 onto the plane where the substrate is located is set as a circle. Of course, it can also be set as a polygon. The present invention does not limit this.

[0078] As shown in Figure 8, the light-emitting element 2 includes a first color light-emitting element 201 and a second color light-emitting element 202. The first dimming interface 31 includes a first sub-dimming interface 311 corresponding to the first color light-emitting element 201 and a second sub-dimming interface 312 corresponding to the second color light-emitting element 202. The second dimming interface 32 includes a third sub-dimming interface 321 corresponding to the first color light-emitting element 201 and a fourth sub-dimming interface 322 corresponding to the second color light-emitting element 202.

[0079] In this embodiment of the invention, the luminous efficiency of the first color light-emitting element 201 is lower than that of the second color light-emitting element 202; the number of first sub-dimming interfaces 311 is greater than the number of second sub-dimming interfaces 312; and / or, the number of third sub-dimming interfaces 321 is greater than the number of fourth sub-dimming interfaces 322. Based on this arrangement, the number of first sub-dimming interfaces 311 and second sub-dimming interfaces 312 can be matched with the luminous efficiency of the first color light-emitting element 201 and the second color light-emitting element 202, respectively. This allows for a greater number of first sub-dimming interfaces 321 to be arranged around the first color light-emitting element 201 with lower luminous efficiency. This enables a greater number of first sub-dimming interfaces 311 to adjust the large-angle light emitted by the light-emitting element 201 and to adjust more large-angle light into small-angle light, thereby increasing the intensity of the small-angle light emitted by the first color light-emitting element 201 and compensating for the insufficient luminous efficiency of the first color light-emitting element 201.

[0080] For example, the light-emitting element 2 mentioned above includes an organic light-emitting diode (OLED), the first color can be blue, the second color can be one of green and red, and the third color can be another of green and red.

[0081] For example, as shown in FIG8, the light-emitting element 2 further includes a third color light-emitting element 203. In this embodiment of the invention, the luminous efficiency of the first color light-emitting element 201 is less than that of the third color light-emitting element 203, the number of first sub-dimming interfaces 311 is greater than the number of first dimming interfaces 31 surrounding the third color light-emitting element 203; and / or, the number of third sub-dimming interfaces 321 is greater than the number of second dimming interfaces 32 surrounding the third color light-emitting element 203.

[0082] For example, as shown in FIG8, the area of ​​the first color light-emitting element 201 can be larger than the area of ​​the second color light-emitting element 202 to compensate for the insufficient luminous efficiency of the first color light-emitting element 201.

[0083] For example, as shown in FIG1, the display panel includes a plurality of light-emitting element groups 200 arranged in an array along a first direction h1 and a second direction h2. FIG1 uses a 2×2 light-emitting element group in the display panel as an illustration, and the first direction h1 intersects the second direction h2. The light-emitting element group 200 includes a plurality of the aforementioned light-emitting elements 2, and the light-emitting elements 2 include a first color light-emitting element 201, a second color light-emitting element 202, and a third color light-emitting element 203. The length y1 of the first color light-emitting element 201 in the second direction h2 is greater than the length y2 of the second color light-emitting element 202 in the second direction h2, and the length of the first color light-emitting element 201 in the second direction h2 is greater than the length y3 of the third color light-emitting element 203 in the second direction h2.

[0084] In the same light-emitting element group 200, the first color light-emitting element 201 and the second color light-emitting element 202 are arranged along a first direction h1, the first color light-emitting element 201 and the third color light-emitting element 203 are arranged along the first direction h1, and the second color light-emitting element 202 and the third color light-emitting element 203 are arranged along a second direction h2. For example, the first color can be blue, the second color can be one of green and red, and the third color can be another of green and red.

[0085] Optionally, as shown in Figure 1, the first dimming interface 31 includes at least a fifth sub-dimming interface 313. The orthographic projection of the fifth sub-dimming interface 313 onto the plane of the substrate 1 is located between the third color light-emitting element 203 of one light-emitting element group 200 and the second color light-emitting element 202 of another light-emitting element group 200. The second dimming interface 32 includes at least a sixth sub-dimming interface 323. The orthographic projection of the sixth sub-dimming interface 323 onto the plane of the substrate 1 is located between the third color light-emitting element 203 of one light-emitting element group 200 and the second color light-emitting element 202 of another light-emitting element group 200. Based on this arrangement, the large-angle light emitted from the third color light-emitting element 203 of one light-emitting element group 200 and the large-angle light emitted from the second color light-emitting element 202 of the other light-emitting element group 200 can both be adjusted by the fifth sub-dimming interface 313 and the sixth sub-dimming interface 323 located between them, and emitted from the display panel at a small angle, thereby achieving a large viewing angle privacy effect of the display panel in the second direction h2.

[0086] Figure 1 illustrates a setup where two fifth sub-dimming interfaces 313 and a sixth sub-dimming interface 323 are included between a third-color light-emitting element 203 in one light-emitting element group 200 and a second-color light-emitting element 202 in another light-emitting element group 200. The sixth sub-dimming interface 323 can adjust both the large-angle light emitted by the third-color light-emitting element 203 of one light-emitting element group 200 and the large-angle light emitted by the second-color light-emitting element 202 of the other light-emitting element group 200.

[0087] For example, as shown in FIG1, in this embodiment of the invention, the orthographic projection of the support portion 6 onto the plane of the substrate 1 is located between two adjacent first color light-emitting elements 201 in the second direction h2. Based on this arrangement, the support portion 6 can be distributed with the first dimming interface 31 and the second dimming interface 32 in different areas of the display panel, thereby making reasonable use of the space in the display panel where no light-emitting elements 2 are provided.

[0088] For example, as shown in FIG1, the display panel includes a dimming component 3, which includes the aforementioned first dimming interface 31 and second dimming interface 32. The dimming component 3 and the support portion 6 are arranged along a first direction h1. Based on this arrangement, the dimming component 3 and the support portion 6 can be located between two adjacent light-emitting element groups 200, which can improve the uniformity of the distribution of the dimming component 3 and the support portion 6 in the display panel.

[0089] Optionally, as shown in FIG1, the first color light-emitting element 201 includes a first sub-light-emitting element 2011 and a second sub-light-emitting element 2012 arranged along the second direction h2, and a third sub-light-emitting element 2013 and a fourth sub-light-emitting element 2014 arranged along the second direction h2.

[0090] When setting each first color light-emitting element 201, for example, as shown in FIG1, along the second direction h2, the embodiment of the present invention can make the distance d1 between the first sub-light-emitting element 2011 and the second sub-light-emitting element 2012 equal to the distance d2 between the third sub-light-emitting element 2013 and the fourth sub-light-emitting element 2014.

[0091] Alternatively, as shown in Figure 9, which is a top view of another display panel provided in an embodiment of the present invention, along the second direction h2, the distance d1 between the first sub-light-emitting element 2011 and the second sub-light-emitting element 2012 is less than the distance d2 between the third sub-light-emitting element 2013 and the fourth sub-light-emitting element 2014. As shown in Figure 9, at least two of the following are included between the third sub-light-emitting element 2013 and the fourth sub-light-emitting element 2014: a support portion 6, a first dimming interface 31, and a second dimming interface 32. Figure 9 illustrates the inclusion of the support portion 6, the first dimming interface 31, and the second dimming interface 32 between the third sub-light-emitting element 2013 and the fourth sub-light-emitting element 2014. Furthermore, it illustrates the arrangement of two first dimming interfaces 31 and two second dimming interfaces 32 between the third sub-light-emitting element 2013 and the fourth sub-light-emitting element 2014. Based on this configuration, the large space between the third sub-light-emitting element 2013 and the fourth sub-light-emitting element 2014 can be reasonably utilized. While ensuring that the support part 6, the first dimming interface 31, and the second dimming interface 32 do not affect the small-angle light emitted by the light-emitting element 2, the requirements for the manufacturing process capabilities of the support part 6, the first dimming interface 31, and the second dimming interface 32 can be reduced, which is conducive to reducing the difficulty of the process.

[0092] Optionally, as shown in Figure 10, which is a top view of another display panel provided in an embodiment of the present invention, the first dimming interface 31 further includes a seventh sub-dimming interface 314. The orthographic projection of the seventh sub-dimming interface 314 onto the plane of the substrate 1 is located between the first color light-emitting element 201 and the second color light-emitting element 202; and / or, the orthographic projection of the seventh sub-dimming interface 314 onto the plane of the substrate 1 is located between the first color light-emitting element 201 and the third color light-emitting element 203.

[0093] As shown in Figure 10, the second dimming interface 32 also includes an eighth sub-dimming interface 324, the orthographic projection of the eighth sub-dimming interface 324 onto the plane of the substrate 1 is located between the first color light-emitting element 201 and the second color light-emitting element 202; and / or, the orthographic projection of the eighth sub-dimming interface 324 onto the plane of the substrate 1 is located between the first color light-emitting element 201 and the third color light-emitting element 203.

[0094] The settings of the seventh sub-dimming interface 314 and the eighth sub-dimming interface 324 can adjust the emission direction of the large-angle light emitted by the first color light-emitting element 201 and the second color light-emitting element 202 towards both sides of the first direction h1, so that this part of the large-angle light is adjusted to be emitted as small-angle light, which can improve the privacy protection effect of the display panel in the first direction h1.

[0095] For example, as shown in FIG10, the display panel includes a dimming component 3, which includes a first dimming interface 31 and a second dimming interface 32; the dimming component 3 includes a first dimming component 301 that at least partially surrounds the first color light-emitting element 201, a second dimming component 302 that at least partially surrounds the second color light-emitting element 202, and a third dimming component 303 that at least partially surrounds the third color light-emitting element 203.

[0096] It should be noted that the quadrilateral shape of the light-emitting element 2 shown in Figure 10 is only an illustration, and the embodiments of the present invention can be set to other shapes according to different design requirements.

[0097] When the shape of the light-emitting element 2 is designed as a quadrilateral, as shown in Figure 10, each side of the light-emitting element 2 is provided with a first dimming interface 31 and a second dimming interface 32. Based on this arrangement, the first dimming interface 31 and the second dimming interface 32 can be used to adjust the large-angle light of the light-emitting element 2 from multiple directions, thereby reducing the light intensity of the display panel at large viewing angles from multiple directions and improving the privacy protection effect at large viewing angles from multiple directions. Furthermore, based on this arrangement, the light intensity of the display panel at a normal viewing angle can also be further improved.

[0098] It should be noted that Figure 10 is only used as an illustration with d1≠d2. When the dimming component 3 is configured to include a first dimming component 301 that at least partially surrounds the first color light-emitting element 201, a second dimming component 302 that at least partially surrounds the second color light-emitting element 202, and a third dimming component 303 that at least partially surrounds the third color light-emitting element 203, d1 can also be set to be not equal to d2. This will not be illustrated in the figure here.

[0099] For example, as shown in FIG10, the second dimming interface 32 in the first dimming component 301 can be reused as the second dimming interface in the second dimming component 302, or it can be reused as the second dimming interface 32 in the third dimming component 303. The second dimming interface in the second dimming component 302 can also be reused as the second dimming interface 32 in the third dimming component 303.

[0100] For example, as shown in FIG11, FIG11 is a top view schematic diagram of another display panel provided in an embodiment of the present invention. The display panel further includes at least one of a first connecting component 81, a second connecting component 82, a third connecting component 83, and a fourth connecting component 84. The first connecting component 81 connects adjacent first dimming components 301 and second dimming components 302 in the first direction h1. The second connecting component 82 connects adjacent second dimming components 302 and third dimming components 303 in the second direction h2. The third connecting component 83 connects adjacent third dimming components 303 and first dimming components 301 in the first direction h1. The fourth connecting component 84 connects two adjacent first dimming components 301 in the second direction h2. The arrangement of at least one of the first connecting component 81, the second connecting component 82, the third connecting component 83, and the fourth connecting component 84 can form a grid structure in the orthographic projection of the dimming components 3 onto the plane of the display panel, which is beneficial to improving the pattern consistency of different areas in the display panel.

[0101] For example, as shown in FIG12, FIG12 is a top view schematic diagram of another display panel provided in an embodiment of the present invention, wherein at least one of the first dimming component 301, the second dimming component 302, and the third dimming component 303 includes a notch 300. FIG13 illustrates the first dimming interface 31 in the first dimming component 301 including a notch 300, the first dimming interface 31 in the second dimming component 302 including a notch 300, and the first dimming interface 31 in the third dimming component 303 including a notch 300.

[0102] The notch 300 can prevent the second electrode 202, which is formed after the first dimming interface 31 and the second dimming interface 32, from being disconnected or thinned at the first dimming interface 31 and the second dimming interface 32. This allows the second electrode 202 of the light-emitting element 2 to be formed into a continuous structure with a large thickness at the first dimming interface 31 and the second dimming interface 32. This helps to reduce the voltage drop of the signal transmitted by the second electrode 202 during transmission, improve the voltage uniformity of the second electrode 202 in the display area, and improve the display uniformity of the display panel.

[0103] Based on the same inventive concept, this embodiment of the invention also provides a display device, as shown in FIG13. FIG13 is a schematic diagram of a display device provided by an embodiment of the invention, the display device including the display panel 100 described above. The specific structure of the display panel 100 has been described in detail in the above embodiments and will not be repeated here. Of course, the display device shown in FIG13 is merely illustrative; the display device can be any electronic device with display function, such as a mobile phone, tablet computer, laptop computer, e-reader, in-vehicle display screen, or television set.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
