[0002] With the continuous development of display technology, consumers' requirements for display screens are constantly increasing. At present, various types of displays, including liquid crystal displays and organic light-emitting displays, are emerging in an endless stream and have been developing rapidly. On this basis, display technologies such as 3D display, touch display technology, curved display, ultra-high resolution display and anti-peep display are constantly emerging.

[0028] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0030] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0031] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0032] At present, flexible vehicle-mounted products generally have an anti-peep film mounted on the module cover. The principle of the anti-peep film is to reduce the distance between the blinds in a regular manner to form a blind layer of ultra-fine blades, so that the light on the screen is only blocked by the narrowest area of ​​the blades, ensuring that the human eye has the highest transmittance and the strongest visibility when looking at the screen; when the angle is tilted, the area of ​​light blocked by the blades increases, and the visible transmittance also decreases, making the screen gradually darker; when the angle is tilted to a certain degree, the degree of screen darkening is completely invisible to the human eye, thus achieving the purpose of 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 display.

[0033] In view of this, an embodiment of the present invention provides a display panel, such as Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of a display panel provided by an embodiment of the present invention, Figure 2 for Figure 1 A cross-sectional schematic diagram along AA′ shows that the display panel includes a substrate 1 , a light emitting element 2 , a first dimming interface 31 and a second dimming interface 32 .

[0034] like Figure 2 As shown, the light-emitting element 2 is located on one side of the substrate 1, the first dimming interface 31 is convex in the direction away from the substrate 1, and, along the direction perpendicular to the plane where the substrate 1 is located, the first dimming interface 31 is staggered with the light-emitting element 2. The second dimming interface 32 is concave in the direction close to the substrate 1, and, along the direction perpendicular to the plane where the substrate 1 is located, the second dimming interface 32 is staggered with the light-emitting element 2.

[0035] When the display panel is working, the light emitting element 2 will emit light with various exit angles. For the large-angle light emitted by the light emitting element 2, wherein the large-angle light refers to the light whose angle between the propagation direction of the light and the normal of the substrate is greater than the first preset angle, this part of the light can be adjusted by the first dimming interface 31 and the second dimming interface 32 to be a small-angle light to emit the display panel. Among them, the small-angle light refers to the light whose angle between the propagation direction of the light and the normal of the substrate is less than the first preset angle. The setting of the first preset angle can be set according to the viewing angle anti-peeping requirements of the display panel. For example, the embodiment of the present invention can set the first preset angle to 45° or 60°.

[0036] Specifically, Figure 2 As shown in the light L11 in FIG. 1 , the light L11 is reflected after being emitted to the first dimming interface 31, and the reflected light can be emitted from the display panel at a smaller emission angle than the light L11. The emission angle refers to the angle between the propagation direction of the light and the normal line of the substrate 1. And, as Figure 2As shown in the light L12 in FIG. 1 , the light L12 is refracted after being emitted to the first dimming interface 31 , and the refracted light can also be emitted from the display panel at a smaller emission angle than the light L12 .

[0037] like Figure 2 As shown in the light L21 in FIG. 1 , the light L21 represents the light emitted by the light emitting element 2, which is reflected by other film layers inside the display panel and emitted to the second dimming interface 32. After being refracted by the second dimming interface 32, the light can be emitted at a smaller emission angle. And, as Figure 2 As shown in the figure, the light L22 represents a large-angle light emitted by the light-emitting element 2 and directly emitted to the second dimming interface 32. After being refracted by the second dimming interface 32, the light can be emitted at a smaller angle.

[0038] It can be seen that based on the above-mentioned setting method provided by the embodiment of the present invention, it is possible to prevent the light emitted by the light emitting element 2 from being emitted from the display panel at a large emission angle, thereby preventing users at a large viewing angle from seeing or seeing the display screen clearly, thereby achieving a large viewing angle anti-peeping effect. Moreover, based on this setting method, the first dimming interface 31 and the second dimming interface 32 can also be used to adjust the original large-angle light to a small-angle light emitted from the display panel, which can improve the light emission utilization rate of the light emitting element 2, increase the brightness of the display panel at a normal viewing angle, and reduce the power consumption of the display panel while ensuring the display brightness of the display panel at a normal viewing angle.

[0039] When the display panel is used for a vehicle-mounted display screen, the first dimming interface 31 and the second dimming interface 32 can narrow the large-angle light emitted by the vehicle-mounted display screen, 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 anti-peeping.

[0040] For example, Figure 1 and Figure 2 As shown, 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 staggered with the light-emitting element 2, and the two are also staggered with each other, so as to avoid the first dimming interface 31 and the second dimming interface 32 from adjusting the small-angle light emitted by the light-emitting element 2, thereby ensuring the display effect of the display panel at a normal viewing angle. Moreover, the embodiment of the present invention can adjust a variety of large-angle light emitted by the light-emitting element 2 by staggering the first dimming interface 31 and the second dimming interface 32 in the direction perpendicular to the plane where the substrate 1 is located.

[0041] In addition, if Figure 2 As shown, the display panel further includes an array layer 30, and the array layer 30 includes metal traces ( Figure 2 ) and a pixel driving circuit (not shown) electrically connected to the light emitting element 2 Figure 2(not shown), the pixel driving circuit includes a thin film transistor. Exemplarily, for the light emitted by the light-emitting element 2 and propagating toward one side of the substrate 1, the metal wiring can reflect this part of the light, and the reflected light can be emitted to the second dimming interface 32 and after being dimmed by the second dimming interface 32, it can be emitted from the display panel at a smaller exit angle, thereby further improving the large-viewing angle anti-peeping effect and increasing the brightness of the display panel at a normal viewing angle. Moreover, based on this setting, it is also possible to prevent light from being emitted to the thin film transistor, thereby preventing the characteristics of the thin film transistor from changing due to light, and ensuring that the thin film transistor has reliable electrical performance.

[0042] For example, Figure 2 As shown, at least part 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 where the substrate 1 is located, at least part 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 part of the large-angle light emitted by the light-emitting element 2 and propagating toward the side away from the substrate 1 can be directed toward the first dimming interface 31, and the first dimming interface 31 adjusts the propagation direction of this part of the large-angle light, so that this part of the light is emitted from the first dimming interface 31 at a smaller exit angle.

[0043] For example, Figure 1 As shown, the embodiment of the present invention can make the first dimming interface 31 and the second dimming interface 32 located between two adjacent light-emitting elements 2. Based on this setting, the distance between the first dimming interface 31 and the second dimming interface 32 can be reduced, so that at least part of the large-angle light emitted by the same light-emitting element 2 can be adjusted by the first dimming interface 31 and the second dimming interface 32 in sequence, further reducing the exit angle of the emitted light.

[0044] For example, Figure 1 and Figure 2 As shown, in the embodiment of the present 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 the direction parallel to the plane where the substrate 1 is located. Based on this setting, at least part of the light emitted through the second dimming interface 32 can continue to be emitted to the first dimming interfaces 31 located on both sides thereof, so that this part of the light can continue to reduce the emission angle through the action of the first dimming interface 31.

[0045] For example, Figure 2As shown, at least part of the second dimming interface 32 is located on the side of the light emitting element 2 close to the substrate 1. Based on this arrangement, at least part of the large-angle light emitted by the light emitting element 2 and propagating toward the side close 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 part of the large-angle light, so that this part of the light is emitted from the second dimming interface 32 at a smaller exit angle.

[0046] For example, Figure 2 As shown, the display panel further includes a pixel definition layer 4 and a protrusion 5, the pixel definition layer 4 includes a first opening 41, the light-emitting element 2 includes a light-emitting layer 20, and at least a portion of the light-emitting layer 20 is located in the first opening 41. The protrusion 5 protrudes from the surface of the pixel definition layer 4 to the side away from the substrate 1; the protrusion 5 includes a first surface S11 on the side away from the substrate 1; and the first dimming interface 31 includes the first surface S11. That is, when the light emitted by the light-emitting element 2 is emitted toward the first surface S11, the emission angle of the light emitted through the first surface S11 can be reduced, thereby reducing the brightness of the display panel at a large viewing angle, and achieving a large viewing angle anti-peeping effect.

[0047] Optional, such as Figure 2 As shown, the pixel definition layer 4 further includes a second opening 42; at least a portion of the second dimming interface 32 includes a side wall S42 of the second opening 42. That is, after the light emitted by the light emitting element 2 is emitted toward the side wall S42, the emission angle of the light emitted through the side wall S42 can be reduced, thereby reducing the brightness of the display panel at a large viewing angle, and achieving a large viewing angle anti-peeping effect.

[0048] Exemplarily, the second opening 42 and the third opening 43 may be formed in the same patterning process. The protrusion 5 may be formed before or after the second opening 42 is formed.

[0049] Exemplarily, the material of the protrusion 5 may be different from the material of the pixel definition layer 4, or may be the same, which is not limited in the embodiment of the present invention.

[0050] For example, Figure 2 As shown, 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 portion of the side wall S42 forming the second opening 42 that is the farthest from the substrate 1. Figure 2 As shown, the first bottom surface S21 and the first top surface S31 are in the same horizontal plane, which is parallel to the plane where the substrate 1 is located. Figure 2The horizontal plane is indicated by a dotted line. The horizontal plane can be used as a boundary between the first dimming interface 31 and the second dimming interface 32, that is, along a direction perpendicular to the plane where the substrate 1 is located, the first dimming interface 31 and the second dimming interface 32 are located on both sides of the horizontal plane.

[0051] For example, Figure 2 As shown, this horizontal plane can be regarded as the surface S40 of the pixel definition layer 4.

[0052] For example, Figure 1 and Figure 3 As shown, Figure 3 for Figure 1 A cross-sectional schematic diagram along BB', the display panel also includes a support portion 6, which protrudes from the surface S40 of the pixel definition layer 4 to the side away from the substrate 1; the support portion 6 is used to support the mask in the evaporation process to ensure the uniformity of evaporation and improve the evaporation yield.

[0053] like Figure 3 As shown, the support portion 6 includes a second surface S12 on a side away from the substrate 1; along a direction perpendicular to the plane where the substrate 1 is located, the distance between the second surface S12 and the light emitting element 2 is h2. Figure 2 As shown, along the direction perpendicular to the plane where the substrate 1 is located, the distance between the first surface S11 and the light-emitting element 2 is h1. Among them, 0

[0054] Illustratively, in an embodiment of the present invention, the bottom surface of the support portion 6 close to the substrate 1 and the bottom surface of the protrusion 5 close to the substrate 1 can be on the same horizontal plane, and the height of the protrusion 5 can be smaller than the height of the support portion 6 to avoid contact between the mask and the protrusion 5 when the support portion 6 is used to support the mask.

[0055] For example, Figure 2 As shown, the first surface S11 intersects with the surface S40 of the pixel definition layer 4 at a first intersection line A1, and the angle between the tangent line of the first surface S11 at the first intersection line A1 and the plane where the substrate 1 is located is θ1. Figure 3 As shown, the second surface S12 intersects with the surface of the pixel definition layer 4 at a second intersection line A2, and the angle between the tangent line of the second surface S12 at the second intersection line A2 and the plane where the substrate 1 is located is θ2, wherein 45°≤θ1≤θ2≤90°.

[0056] ​Based on this setting, on the one hand, the angle between the tangent of the first surface S11 at the first intersection A1 and the plane where the substrate 1 is located can be made smaller, that is, the first surface S11 is less inclined relative to the plane where the substrate 1 is located, which is conducive to the first surface S11 receiving more large-angle light emitted by the light-emitting element 2, and adjusting more large-angle light to be emitted at a small angle, further improving the wide-angle anti-peeping effect of the display panel. On the other hand, the embodiment of the present invention makes the angle between the tangent of the second surface S12 at the second intersection A2 and the plane where the substrate 1 is located larger, so that the second surface S12 can be more inclined than the plane where the substrate 1 is located. While making the height of the support portion 6 reach the height required to support the mask, it can avoid setting the area of ​​the support portion 6 larger, which is conducive to using more space in the display panel to set the light-emitting element 2, that is, increasing the area of ​​the light-emitting element 2 and improving the aperture ratio.

[0057] Optional, such as Figure 1 As shown, along the direction parallel to the plane where the substrate 1 is located, the distance between the protrusion 5 and the nearest light-emitting element 2 is L1, and the distance between the support portion 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, so that the first surface S11 of the protrusion 5 can 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 is beneficial to reduce the large-angle light intensity and improve the anti-peeping effect.

[0058] For example, Figure 2 As shown, the width of the raised portion 5 gradually decreases in the direction away from the substrate 1. The light emitted by the light-emitting element 2 may be reflected when it is emitted to the first surface S11. By gradually reducing the width of the raised portion 5 in the direction away from the substrate 1, the embodiment of the present invention can make the light reflected by the first surface S11 emit toward the light-emitting side of the display panel, which is beneficial to improve the brightness of the display panel. Moreover, based on this arrangement, when other film layers are subsequently formed above the raised portion 5, it is possible to avoid the film layers arranged above the raised portion 5 from being disconnected at the position where the raised portion 5 is located. For example, when the cathode of the light-emitting element 2 is arranged above the raised portion 5, based on this arrangement, it is possible to avoid the cathode from being disconnected at the raised portion 5, which is beneficial to improve the connection reliability of the cathode.

[0059] For example, Figure 2As shown, the width of the second opening 42 gradually decreases in 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 arranged above the second opening 42 from being disconnected at the location where the second opening 42 is located. For example, when the cathode of the light-emitting element 2 is arranged above the second opening 42, based on this arrangement, it is possible to avoid the cathode from being disconnected at the second opening 42, which is beneficial to improving the connection reliability of the cathode.

[0060] For example, Figure 2 As shown, in the embodiment of the present invention, the side of the first dimming interface 31 away from the substrate 1 may include a curved surface. Figure 2 The cross-sectional shape of the first dimming interface 31 is an arc as an example. Alternatively, in the embodiment of the present invention, the side of the first dimming interface 31 away from the substrate 1 may include a plane. Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 for Figure 1 Two other cross-sectional diagrams along AA' are shown in Figure 4 In the embodiment, the cross-sectional shape of the first dimming interface 31 is a trapezoid. Figure 5 In the embodiment, the cross-sectional shape of the first dimming interface 31 is a triangle.

[0061] Optionally, in the embodiment of the present invention, the side of the second dimming interface 32 close to the substrate 1 may include a flat surface or a curved surface.

[0062] For example, Figure 6 As shown, Figure 6 for Figure 1 In another cross-sectional view along AA', the display panel further includes a first film layer 71 covering the protrusion 5, the first film layer 71 is in contact with the protrusion 5, and the first surface S11 is the contact surface between the two. In the embodiment of the present invention, the refractive index of the first film layer 71 is less than the refractive index of the protrusion 5.

[0063] When the light emitting element 2 is turned on, Figure 6 As shown, the large-angle light emitted by the light-emitting element 2 can irradiate the interface between the protrusion 5 and the first film layer 71, that is, the above-mentioned first surface S11. In the embodiment of the present invention, by making the refractive index of the first film layer 71 smaller than the refractive index of the protrusion 5, when the light passes through the first surface S11 from the inside of the protrusion 5 to 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 toward the normal direction close to the substrate 1, that is, the first surface S11 can adjust the large-angle light to emit a small-angle light, thereby improving the brightness at a positive viewing angle, and reducing the large-angle light intensity, thereby achieving a large-viewing angle anti-peeping effect.

[0064] For example, Figure 6 As shown, 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 in a direction perpendicular to the plane where the substrate 1 is located. In the embodiment of the present 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 part of the first sub-common layer 231 is located between the first electrode 21 and the light-emitting layer 20, and at least part 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 part of the second sub-common layer 232 includes an electron injection layer and / or an electron transport layer.

[0065] Optional, such as Figure 6 As shown, the display panel further includes a second film layer 72 at least partially located in the second opening 42, and the second film layer 72 is in contact with the side wall S42 of the second opening 42, and the second dimming interface 32 is a contact surface between the second film layer 72 and the side wall S42 of the second opening 42. In the embodiment of the present 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, the large-angle light emitted from the pixel definition layer 4 through the second dimming interface 32 to the second film layer 72 can be adjusted to a small-angle light.

[0066] For example, Figure 7 As shown, Figure 7 for Figure 1 In another cross-sectional schematic diagram along AA', the display panel further includes a planarization layer 8, and the planarization layer 8 is located on the side of the pixel definition layer 4 close to the substrate 1. The planarization layer 8 includes a third opening 43, and the third opening 43 at least partially overlaps with the second opening 42 along a direction perpendicular to the plane where the substrate 1 is located, and at least a part of the second dimming interface 32 includes a side wall S43 of the third opening 43. The provision of the third opening 43 can increase the area of ​​the second dimming interface 32 on the basis of the second opening 42, so that the second dimming interface 32 can be used to receive more large-angle light emitted by the light-emitting element 2, and more large-angle light emitted by the light-emitting element 2 can be adjusted to prevent more large-angle light from being emitted from the display panel, which can further improve the wide-viewing angle anti-peeping effect of the display panel.

[0067] For example, Figure 7As shown, at least part of the second film layer 72 is also located in the third opening 43, and the second film layer 72 is in contact with the side wall S42 of the second opening 42 and the side wall S43 of the third opening 43, respectively. The part of the second dimming interface 32 is the contact surface between the second film layer 72 and the side wall S42 of the second opening 42, and the other part of the second dimming interface 32 is the contact surface between the second film layer 72 and the side wall S43 of the third opening 43. In the embodiment of the present invention, the refractive index of the second film layer 72 is greater than the refractive index of the planarization layer 8. Based on this setting, according to the law of refraction, the large-angle light emitted from the planarization layer 8 through the second dimming interface 32 to the second film layer 72 can be adjusted to a small-angle light.

[0068] It should be noted that Figure 7 The third opening 43 penetrating the planarization layer 8 is only for illustration. In the embodiment of the present invention, the depth of the third opening 43 may be smaller than the thickness of the planarization layer 8 , that is, the third opening 43 may not penetrate the planarization layer 8 .

[0069] For example, Figure 7 As shown, 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 in a direction perpendicular to the plane where the substrate 1 is located, and the second film layer 72 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 part of the first sub-common layer 231 is located between the first electrode 21 and the light-emitting layer 20, and at least part 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 part of the second sub-common layer 232 includes an electron injection layer and / or an electron transport layer.

[0070] For example, the second film layer 72 and the first film layer 71 may be formed by using the same material and in the same process, and the two may be two parts of the same film layer in different regions, that is, there may be no boundary line between the two.

[0071] In this case, the refractive index of the protrusion 5 is different from the refractive index of the pixel definition layer 4, and the two can be formed of different materials.

[0072] like Figure 6 and Figure 7 As shown, based on the morphological characteristics of the protrusion 5, the path for the lateral leakage current to be transmitted between two adjacent light-emitting elements 2 through the common layer 23 can be extended, thereby suppressing the transmission of the lateral leakage current and avoiding the light-emitting element 2 that should not be lit from being lit secretly, thereby improving the display effect.

[0073] In addition, the common layer 23 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 for the lateral leakage current to be transmitted between two adjacent light-emitting elements 2 through the common layer 23 can be extended, thereby suppressing the transmission of the lateral leakage current and improving the display effect.

[0074] For example, Figure 1 As shown, the orthographic projection shape of the first dimming interface 31 and the second dimming interface 32 on the plane where the substrate 1 is located can be a strip structure, such as Figure 1 As shown, 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 of the first dimming interface 31 and the second dimming interface 32 in the second direction h2.

[0075] Alternatively, in the embodiment of the present invention, the orthographic projection shape of at least one of the first dimming interface 31 and the second dimming interface 32 on the plane where the substrate 1 is located may be set to a block structure.

[0076] For example, Figure 8 As shown, Figure 8 A schematic 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 arranged corresponding to the light-emitting elements 2; the orthographic projection of the first dimming interface 31 on 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, Figure 8 The shape of the orthographic projection of the first dimming interface 31 on the plane where the substrate is located is set to be a circle as an illustration. Of course, it can also be set to be a polygon, which is not limited in the embodiment of the present invention.

[0077] like Figure 8 As shown, 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 set corresponding to the first color light-emitting element 201 and a second sub-dimming interface 312 set corresponding to the second color light-emitting element 202. The second dimming interface 32 includes a third sub-dimming interface 321 set corresponding to the first color light-emitting element 201 and a fourth sub-dimming interface 322 set corresponding to the second color light-emitting element 202.

[0078] In the embodiment of the present 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 the first sub-dimming interfaces 311 is greater than the number of the second sub-dimming interfaces 312; and / or the number of the third sub-dimming interfaces 321 is greater than the number of the fourth sub-dimming interfaces 322. Based on this setting, the number of the first sub-dimming interfaces 311 and the 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, so that a larger number of first sub-dimming interfaces 321 are set around the periphery of the first color light-emitting element 201 with lower luminous efficiency, so that a larger number of first sub-dimming interfaces 311 can adjust the large-angle light emitted by the light-emitting element 2, and adjust more large-angle light to be emitted as small-angle light, thereby increasing the intensity of the small-angle light emitted by the first color light-emitting element 201 to compensate for the insufficient luminous efficiency of the first color light-emitting element 201.

[0079] Exemplarily, the light-emitting element 2 includes an organic light-emitting diode (OLED), the first color may be blue, the second color may be one of green and red, and the third color may be the other of green and red.

[0080] For example, Figure 8 As shown, the light-emitting element 2 further includes a third color light-emitting element 203. In the embodiment of the present invention, the luminous efficiency of the first color light-emitting element 201 is less than the luminous efficiency of the third color light-emitting element 203, the number of the first sub-dimming interfaces 311 is greater than the number of the first dimming interfaces 31 around the third color light-emitting element 203; and / or, the number of the third sub-dimming interfaces 321 is greater than the number of the second dimming interfaces 32 around the third color light-emitting element 203.

[0081] For example, Figure 8 As shown, the area of ​​the first color light emitting element 201 may be larger than the area of ​​the second color light emitting element 202 to compensate for the insufficient light emitting efficiency of the first color light emitting element 201 .

[0082] For example, Figure 1 As shown, 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. Figure 1Taking 2×2 light-emitting element groups in the display panel as an example, the first direction h1 intersects with the second direction h2; the light-emitting element group 200 includes a plurality of the above-mentioned light-emitting elements 2, and the light-emitting element 2 includes 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;

[0083] 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 the 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 the second direction h2. Exemplarily, the first color may be blue, the second color may be one of green and red, and the third color may be the other of green and red.

[0084] Optional, such as Figure 1 As shown, the first dimming interface 31 includes at least a fifth sub-dimming interface 313, and the orthographic projection of the fifth sub-dimming interface 313 on the plane where the substrate 1 is located is located between the third color light-emitting element 203 of one of the light-emitting element groups 200 and the second color light-emitting element 202 of the other light-emitting element group 200. The second dimming interface 32 includes at least a sixth sub-dimming interface 323, and the orthographic projection of the sixth sub-dimming interface 323 on the plane where the substrate 1 is located is located between the third color light-emitting element 203 of one of the light-emitting element groups 200 and the second color light-emitting element 202 of the other light-emitting element group 200. Based on this setting, the large-angle light emitted by the third color light-emitting element 203 of one of the light-emitting element groups 200 and the large-angle light emitted by the second color light-emitting element 202 of the other light-emitting element group 200 can be adjusted by the fifth sub-dimming interface 313 and the sixth sub-dimming interface 323 located therebetween, and emitted from the display panel as small-angle light, thereby achieving a large-viewing-angle anti-peeping effect of the display panel in the second direction h2.

[0085] Figure 1As an example, two fifth sub-dimming interfaces 313 and one sixth sub-dimming interface 323 are included 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 sixth sub-dimming interface 323 can adjust the large-angle light emitted by the third color light emitting element 203 of one light emitting element group 200, and can also adjust the large-angle light emitted by the second color light emitting element 202 of another light emitting element group 200.

[0086] For example, Figure 1 As shown, in the embodiment of the present invention, the orthographic projection of the support portion 6 on the plane where the substrate 1 is located can be located between two adjacent first color light-emitting elements 201 in the second direction h2. Based on this arrangement, the support portion 6 and the first dimming interface 31 and the second dimming interface 32 can be dispersedly arranged in different areas of the display panel, respectively, so that the space of the area where the light-emitting element 2 is not arranged in the display panel can be reasonably utilized.

[0087] For example, Figure 1 As shown, the display panel includes a dimming component 3, the dimming component 3 includes the above-mentioned first dimming interface 31 and second dimming interface 32, and the dimming component 3 and the support portion 6 are arranged along the 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 distribution uniformity of the dimming component 3 and the support portion 6 in the display panel.

[0088] Optional, such as Figure 1 As shown, 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.

[0089] When each first color light emitting element 201 is set, for example, Figure 1 As shown, 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.

[0090] Or, if Fig. 9 As shown, Fig. 9 A schematic top view of another display panel provided by 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 smaller than the distance d2 between the third sub-light emitting element 2013 and the fourth sub-light emitting element 2014. Fig. 9As shown, at least two of the support portion 6 , the first dimming interface 31 , and the second dimming interface 32 are included between the third sub-light emitting element 2013 and the fourth sub-light emitting element 2014 . Fig. 9 The support portion 6, the first dimming interface 31, and the second dimming interface 32 are provided between the third sub-light emitting element 2013 and the fourth sub-light emitting element 2014 as an example. Two first dimming interfaces 31 and two second dimming interfaces 32 are provided between the third sub-light emitting element 2013 and the fourth sub-light emitting element 2014 as an example. Based on this arrangement, the larger space between the third sub-light emitting element 2013 and the fourth sub-light emitting element 2014 can be reasonably utilized, and while ensuring that the support portion 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 portion 6, the first dimming interface 31, and the second dimming interface 32 can be reduced, which is conducive to reducing the process difficulty.

[0091] Optional, such as Fig.10 As shown, Fig.10 A top view schematic diagram of another display panel provided in an embodiment of the present invention, wherein the first dimming interface 31 also includes a seventh sub-dimming interface 314, and the orthographic projection of the seventh sub-dimming interface 314 on the plane where the substrate 1 is located 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 on the plane where the substrate 1 is located is located between the first color light-emitting element 201 and the third color light-emitting element 203.

[0092] like Fig.10 As shown, the second dimming interface 32 also includes an eighth sub-dimming interface 324, and the orthographic projection of the eighth sub-dimming interface 324 on the plane where the substrate 1 is located 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 on the plane where the substrate 1 is located is located between the first color light-emitting element 201 and the third color light-emitting element 203.

[0093] The setting 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 toward 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 wide-angle anti-peeping effect of the display panel in the first direction h1.

[0094] For example, Fig.10As shown, the display panel includes a dimming component 3, the dimming component 3 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.

[0095] It should be noted that Fig.10 The light emitting element 2 is designed to be a quadrilateral for illustration only. In the embodiment of the present invention, the light emitting element 2 can be designed to be other shapes according to different design requirements.

[0096] When the shape of the light emitting element 2 is designed to be a quadrilateral, as shown in FIG. Fig.10 As shown, each side of the light emitting element 2 is correspondingly 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 wide-angle light of the light emitting element 2 from multiple directions to reduce the wide-angle light intensity of the display panel in multiple directions and improve the wide-angle anti-peeping effect in multiple directions. Moreover, based on this arrangement, the light intensity of the display panel at a normal viewing angle can also be further improved.

[0097] It should be noted that Fig.10 It is only taken as an illustration that d1≠d2. When the dimming component 3 is set 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, and no further illustration is given here.

[0098] For example, Fig.10 As shown, the second dimming interface 32 in the first dimming component 301 can be multiplexed as the second dimming interface in the second dimming component 302, and can also be multiplexed 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 multiplexed as the second dimming interface 32 in the third dimming component 303.

[0099] For example, Fig.11 As shown, Fig.11A schematic top view of another display panel provided by an embodiment of the present invention, the display panel further comprises 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 the first dimming component 301 and the second dimming component 302 adjacent in the first direction h1, the second connecting component 82 connects the second dimming component 302 and the third dimming component 303 adjacent in the second direction h2, the third connecting component 83 connects the third dimming component 303 and the first dimming component 301 adjacent in the first direction h1, and the fourth connecting component 84 connects two first dimming components 301 adjacent in the second direction h2. The provision 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-like structure in the shape of the orthographic projection of the dimming component 3 on the plane where the display panel is located, which is conducive to improving the pattern consistency of different areas in the display panel.

[0100] For example, Fig.12 As shown, Fig.12 The schematic top view of another display panel provided by an embodiment of the present invention is as follows. At least one of the first dimming component 301 , the second dimming component 302 and the third dimming component 303 includes a notch 300 . Fig.13 For example, the first dimming interface 31 in the first dimming component 301 includes a notch 300 , the first dimming interface 31 in the second dimming component 302 includes a notch 300 , and the first dimming interface 31 in the third dimming component 303 includes a notch 300 .

[0101] The setting of the notch 300 can avoid the second electrode 202 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, and can make the second electrode 202 of the light-emitting element 2 form a continuous structure with a large thickness at the first dimming interface 31 and the second dimming interface 32, which is beneficial to reducing the voltage drop of the signal transmitted by the second electrode 202 during the transmission process, improving the voltage uniformity of the second electrode 202 in the display area, and improving the display uniformity of the display panel.

[0102] Based on the same inventive concept, an embodiment of the present invention further provides a display device, such as Fig.13 As shown, Fig.13 Schematic diagram of a display device provided in an embodiment of the present invention, the display device includes the above-mentioned display panel 100. The specific structure of the display panel 100 has been described in detail in the above-mentioned embodiment, and will not be repeated here. Fig.13The display device shown is for illustration only, and the display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a laptop computer, an e-reader, a car display screen or a television.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
