Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the development of technology, people are increasingly using devices with display panels to handle work and daily affairs. Typically, these devices have a wide viewing angle, allowing users at different viewing angles to see the displayed information. To prevent the display panel's content from being seen by others and causing inconvenience, people have put forward requirements for the anti-peeping performance of display panels.

[0003] In the related art, additional polarizing films, light control films, microlenses and other structures are usually provided on the light-emitting side of the display panel to achieve privacy protection, which increases the additional process cost and structural complexity. Summary of the Invention

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present disclosure provides a display panel and a display device, which have an anti-peep mode and a sharing mode and are conducive to reducing production costs.

[0005] The present disclosure provides a display panel, comprising: a substrate; a plurality of light-emitting elements, the light-emitting elements being located on one side of the substrate, the light-emitting elements comprising a first light-emitting element and a second light-emitting element; a pixel definition layer, the pixel definition layer being located on one side of the substrate, the pixel definition layer comprising a first pixel opening and a second pixel opening, the first light-emitting element being at least partially located within the first pixel opening, and the second light-emitting element being at least partially located within the second pixel opening; a light-shielding layer, the light-shielding layer being located on a side of the light-emitting element away from the substrate, the light-shielding layer comprising a first light-transmitting opening and a second light-transmitting opening, the first light-transmitting opening corresponding to the first pixel opening, and a vertical projection of the first pixel opening on the substrate being located within a vertical projection of the first light-transmitting opening corresponding to the first pixel opening, and the second light-transmitting opening corresponding to the first pixel opening. The second pixel opening corresponds to the first pixel opening, and the vertical projection of the second pixel opening on the substrate substrate is located within the vertical projection of the second light-transmitting opening corresponding to it on the substrate substrate; the maximum distance between the edge of the vertical projection pattern of the first light-transmitting opening on the substrate substrate and the edge of the vertical projection pattern of the first pixel opening corresponding to it on the substrate substrate is L1, and the maximum distance between the edge of the vertical projection pattern of the second light-transmitting opening on the substrate substrate and the edge of the vertical projection pattern of the second pixel opening corresponding to it on the substrate substrate is L2, wherein L1<L2; the display mode of the display panel includes an anti-peep mode and a sharing mode; in the anti-peep mode, the first light-emitting element emits light and the second light-emitting element does not emit light; in the sharing mode, the first light-emitting element does not emit light and the second light-emitting element emits light.

[0006] The present disclosure also provides a display device, comprising the above-mentioned display panel.

[0007] The technical solution provided by the present disclosure has the following advantages compared with the existing technology:

[0008] In the display panel provided by the present disclosure, the maximum spacing between the edge of the vertical projection pattern of the first light-transmitting opening on the substrate and the edge of the vertical projection pattern of the first pixel opening corresponding thereto is L1, and the maximum spacing between the edge of the vertical projection pattern of the second light-transmitting opening on the substrate and the edge of the vertical projection pattern of the second pixel opening corresponding thereto is L2, wherein L1<L2. That is, the maximum spacing between the edge of the vertical projection pattern of the first light-transmitting opening on the substrate and the edge of the vertical projection pattern of the first pixel opening corresponding thereto is small, so that the wide-viewing angle light emitted by the first light-emitting element in the first pixel opening cannot be emitted from the first light-transmitting opening corresponding thereto. The maximum spacing between the edge of the vertical projection pattern of the second light-transmitting opening on the substrate and the edge of the vertical projection pattern of the second pixel opening corresponding thereto is large, so that the wide-viewing angle light emitted by the second light-emitting element in the second pixel opening can be emitted from the second light-transmitting opening corresponding thereto. In anti-peep mode, the first light-emitting element emits light and the second light-emitting element does not. Since the wide-angle light emitted by the first light-emitting element in the first pixel opening cannot be emitted from the corresponding first light-transmitting opening, only the narrow-angle light and the normal-angle light can be emitted from the corresponding first light-transmitting opening. Since the user's human eye usually observes the display panel from the normal viewing angle, the user can view the display screen of the display panel normally. However, when the user at the wide-angle viewing position views the display panel, no wide-angle light is emitted from the light-emitting surface of the display panel, and the user at the wide-angle viewing position cannot view the display screen of the display panel, thereby achieving the anti-peep mode. In sharing mode, the first light-emitting element does not emit light, and the second light-emitting element emits light. The wide-angle light emitted by the second light-emitting element in the second pixel opening can be emitted from the corresponding second light-transmitting opening. The narrow-angle light and the normal-angle light emitted by the second light-emitting element in the second pixel opening can also be emitted from the corresponding second light-transmitting opening. Therefore, the user at the wide-angle viewing position can also view the display screen of the display panel without affecting the effect of the display screen viewed by the user at the wide-angle viewing position, thereby achieving the sharing function. At the same time, the display panel can have an anti-peep mode and a sharing mode by setting a light-shielding layer, without the need to set up an additional anti-peep film layer, which is conducive to reducing process difficulty and production costs.

[0009] Correspondingly, the display device provided by the present disclosure also has the above technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0025] Figure 1 is a planar schematic diagram of a display panel provided by the present disclosure, Figure 2 is a planar schematic diagram of a first pixel unit provided by the present disclosure, Figure 3 yes Figure 2 A cross-sectional view of the first pixel unit along AA', Figure 4 is a planar schematic diagram of a second pixel unit provided by the present disclosure, Figure 5 yes Figure 4 A cross-sectional view of the second pixel unit along BB', referring to Figure 1-Figure 5 , this embodiment provides a display panel, the display panel includes: a base substrate 10;

[0026] A plurality of light-emitting elements 20 , the light-emitting elements 20 are located on one side of the base substrate 10 , and the light-emitting elements 20 include a first light-emitting element 21 and a second light-emitting element 22 ;

[0027] A pixel definition layer 30 is located on one side of the base substrate 10 . The pixel definition layer 30 includes a first pixel opening 31 and a second pixel opening 32 . The first light-emitting element 21 is at least partially located within the first pixel opening 31 , and the second light-emitting element 22 is at least partially located within the second pixel opening 32 .

[0028] a light-shielding layer 40 , which is located on a side of the light-emitting element 20 away from the base substrate 10 , and includes a first light-transmitting opening 41 and a second light-transmitting opening 42 . The first light-transmitting opening 41 corresponds to the first pixel opening 31 , and a vertical projection of the first pixel opening 31 on the base substrate 10 is located within a vertical projection of the corresponding first light-transmitting opening 41 on the base substrate 10 . The second light-transmitting opening 42 corresponds to the second pixel opening 32 , and a vertical projection of the second pixel opening 32 on the base substrate 10 is located within a vertical projection of the corresponding second light-transmitting opening 42 on the base substrate 10 .

[0029] The maximum distance between the edge of the vertical projection pattern of the first light-transmitting opening 41 on the substrate 10 and the edge of the vertical projection pattern of the corresponding first pixel opening 31 on the substrate 10 is L1, and the maximum distance between the edge of the vertical projection pattern of the second light-transmitting opening 42 on the substrate 10 and the edge of the vertical projection pattern of the corresponding second pixel opening 32 on the substrate 10 is L2, where L1<L2;

[0030] The display modes of the display panel include anti-peeping mode and sharing mode;

[0031] In the anti-peeping mode, the first light-emitting element 21 emits light, and the second light-emitting element 22 does not emit light;

[0032] In the sharing mode, the first light emitting element 21 does not emit light, and the second light emitting element 22 emits light.

[0033] Specifically, the display panel provided in the embodiments of the present disclosure includes a base substrate 10. The base substrate 10 can be a rigid substrate made of glass. The base substrate 10 can also be a flexible substrate made of polyimide (PI), polycarbonate (PC), or polyethylene terephthalate (PET). The base substrate 10 is used to support and protect the film layers formed thereon.

[0034] Optionally, the display panel also includes an array layer 50 provided on the base substrate 10, the array layer 50 includes a pixel circuit for driving the light-emitting element 20 to emit light, a pixel circuit corresponds to at least one light-emitting element 20, and the light-emitting element 20 is electrically connected to the pixel circuit corresponding thereto, that is, the light-emitting element 20 electrically connected to the same pixel circuit constitutes a sub-pixel, or in other words, the pixel circuit and the light-emitting element 20 electrically connected to the pixel circuit together constitute a sub-pixel, and a plurality of sub-pixels display the screen together. For example, if two light-emitting elements 20 are electrically connected to the same pixel circuit, the two light-emitting elements 20 and the pixel circuit together constitute a sub-pixel. It should be noted that the specific circuit structure of the pixel circuit can be set by those skilled in the art according to actual conditions, for example, it can be a 2T1C (two transistors and one capacitor), 7T1C, 8T1C and other circuits in the related art, and this disclosure does not specifically limit this.

[0035] It should be noted that Figure 2 and Figure 4 The figure exemplarily shows that the vertical projection pattern of the light-emitting element 20 on the plane where the base substrate 10 is located is a rectangle. In other embodiments of the present disclosure, the vertical projection pattern of the light-emitting element 20 on the plane where the base substrate 10 is located can also be other shapes, which will not be repeated in this disclosure.

[0036] The display panel also includes a plurality of light-emitting elements 20 and a pixel definition layer 30. The light-emitting elements 20 are located on one side of the base substrate 10 and include a first light-emitting element 21 and a second light-emitting element 22. The pixel definition layer 30 is located on one side of the base substrate 10 and includes a first pixel opening 31 and a second pixel opening 32. The first pixel opening 31 and the second pixel opening 32 are each used to define a light-emitting area. The first light-emitting element 21 is at least partially located within the first pixel opening 31, i.e., the light-emitting area defined by the first pixel opening 31 is used to accommodate the first light-emitting element 21. The second light-emitting element 22 is at least partially located within the second pixel opening 32, i.e., the light-emitting area defined by the second pixel opening 32 is used to accommodate the second light-emitting element 22. Optionally, the light-emitting element 20 may be an organic light-emitting diode (OLED). The light-emitting element 20 includes a first electrode 201, a light-emitting layer 202, and a second electrode 203, which are sequentially arranged. The first electrode 201 is an insulated image-forming structure and serves as an anode. The second electrodes 203 of the light-emitting elements 20 are connected to each other. The second electrode 203 is a common electrode of each light-emitting element 20 and serves as a cathode.

[0037] It should be noted that Figure 2 and Figure 4 , the first electrode 201 is exemplarily shown as an anode and the second electrode 203 is a cathode. In other embodiments of the present disclosure, the first electrode 201 may also be a cathode and the second electrode 203 may also be an anode. Of course, in other embodiments of the present disclosure, the light-emitting element 20 may also be a micro-light-emitting diode (Micro-LED) or a sub-millimeter light-emitting diode (Mini-LED), which will not be described in detail in this disclosure.

[0038] The display panel further includes a light-shielding layer 40, which is located on a side of the light-emitting element 20 away from the base substrate 10. The light-shielding layer 40 includes a first light-transmitting opening 41 and a second light-transmitting opening 42. The first light-transmitting opening 41 corresponds to the first pixel opening 31, and the vertical projection of the first pixel opening 31 on the base substrate 10 is located within the vertical projection of the corresponding first light-transmitting opening 41 on the base substrate 10. That is, the first light-transmitting opening 41 exposes the corresponding first light-emitting element 21, and at least a portion of the light emitted by the first light-emitting element 21 can be emitted through the corresponding first light-transmitting opening 41. The second light-transmitting opening 42 corresponds to the second pixel opening 32, and the vertical projection of the second pixel opening 32 on the base substrate 10 is located within the vertical projection of the corresponding second light-transmitting opening 42 on the base substrate 10. That is, the second light-transmitting opening 42 exposes the corresponding second light-emitting element 22, and at least a portion of the light emitted by the second light-emitting element 22 can be emitted through the corresponding second light-transmitting opening 42. The maximum distance between the edge of the vertical projection pattern of the first light-transmitting opening 41 on the substrate 10 and the edge of the vertical projection pattern of the corresponding first pixel opening 31 on the substrate 10 is L1, and the maximum distance between the edge of the vertical projection pattern of the second light-transmitting opening 42 on the substrate 10 and the edge of the vertical projection pattern of the corresponding second pixel opening 32 on the substrate 10 is L2, where L1<L2. That is, the maximum distance between the edge of the vertical projection pattern of the first light-transmitting opening 41 on the substrate 10 and the edge of the vertical projection pattern of the corresponding first pixel opening 31 on the substrate 10 is small, so that the wide-angle light emitted by the first light-emitting element 21 in the first pixel opening 31 cannot be emitted from the corresponding first light-transmitting opening 41. The maximum distance between the edge of the vertical projection pattern of the second light-transmitting opening 42 on the substrate 10 and the edge of the vertical projection pattern of the corresponding second pixel opening 32 on the substrate 10 is large, so that the wide-angle light emitted by the second light-emitting element 22 in the second pixel opening 32 can be emitted from the corresponding second light-transmitting opening 42.

[0039] The display panel provided by the present disclosure has an anti-peeping mode and a sharing mode.

[0040] In anti-peeping mode, the first light-emitting element 21 emits light, and the second light-emitting element 22 does not emit light. Since the wide-angle light emitted by the first light-emitting element 21 in the first pixel opening 31 cannot be emitted from the corresponding first light-transmitting opening 41, only the narrow-angle light and the normal-angle light of the light emitted by the first light-emitting element 21 in the first pixel opening 31 can be emitted from the corresponding first light-transmitting opening 41. Since the user's eyes usually observe the display panel from the normal viewing angle, the user can normally view the display screen of the display panel. However, when a user at a wide-angle viewing position views the display panel, no wide-angle light is emitted from the light-emitting surface of the display panel, and the user at a wide-angle viewing position cannot view the display screen of the display panel, thereby achieving the anti-peeping function. In sharing mode, the first light-emitting element 21 does not emit light, while the second light-emitting element 22 emits light. The wide-angle light emitted by the second light-emitting element 22 in the second pixel opening 32 can be emitted from the corresponding second light-transmitting opening 42. The narrow-angle light and the normal-angle light emitted by the second light-emitting element 22 in the second pixel opening 32 can also be emitted from the corresponding second light-transmitting opening 42. As a result, users at a wide-angle position can also view the display screen of the display panel without affecting the effect of the display screen viewed by users at the wide-angle position, thereby realizing the sharing function. At the same time, the provision of the light-shielding layer 40 can realize the display panel having both anti-peeping mode and sharing mode, without the need for a separate anti-peeping film layer, which helps to reduce process difficulty and production costs.

[0041] It should be noted that the positive viewing angle light refers to the light emitted in the direction perpendicular to the light emitting surface of the display panel, the wide viewing angle light refers to the light having a larger angle with the direction perpendicular to the light emitting surface of the display panel, and the narrow viewing angle light refers to the light having a smaller angle with the direction perpendicular to the light emitting surface of the display panel. For example, among the light rays emitted from the backlight surface of the display panel toward the light emitting surface of the display panel, the light rays having an angle greater than 30° with the direction perpendicular to the light emitting surface of the display panel are wide viewing angle light rays, and the light rays having an angle less than 30° with the direction perpendicular to the light emitting surface of the display panel are narrow viewing angle light rays. Of course, in other embodiments of the present disclosure, the judgment of wide viewing angle and narrow viewing angle can also be judged based on other angles according to the angle between the light rays and the direction perpendicular to the light emitting surface of the display panel, and the present disclosure will not elaborate on them one by one here. In the relevant embodiments of the present disclosure, the relevant descriptions are applicable, and the present disclosure will not elaborate on them again.

[0042] Figure 6 is a planar schematic diagram of another first pixel unit provided by the present disclosure, Figure 7 yes Figure 6 A cross-sectional view of the first pixel unit along AA', referring to Figure 1 、 Figure 4-Figure 7 , in some optional embodiments, L1=0, L2>0.

[0043] Specifically, refer to Figure 4 and Figure 5 , L2>0, that is, the maximum distance between the edge of the vertical projection pattern of the second light-transmitting opening 42 on the substrate 10 and the edge of the vertical projection pattern of the corresponding second pixel opening 32 on the substrate 10 is greater than 0, so that the wide-viewing angle light emitted by the second light-emitting element 22 in the second pixel opening 32 can be emitted from the corresponding second light-transmitting opening 42. When the display panel is in sharing mode, the first light-emitting element 21 does not emit light, and the second light-emitting element 22 emits light. The wide-viewing angle light emitted by the second light-emitting element 22 in the second pixel opening 32 can be emitted from the corresponding second light-transmitting opening 42. The small-viewing angle light and the normal-viewing angle light emitted by the second light-emitting element 22 in the second pixel opening 32 can also be emitted from the corresponding second light-transmitting opening 42. Therefore, a user at a wide-viewing angle position can also view the display screen of the display panel without affecting the display screen effect of the display panel viewed by the user at the wide-viewing angle position, thereby realizing the sharing function.

[0044] refer to Figure 6 and Figure 7 , L1=0, that is, the maximum distance between the edge of the vertical projection pattern of the first light-transmitting opening 41 on the substrate 10 and the edge of the vertical projection pattern of the corresponding first pixel opening 31 on the substrate 10 is 0. Optionally, the edge of the vertical projection pattern of the first light-transmitting opening 41 on the substrate 10 and the edge of the vertical projection pattern of the corresponding first pixel opening 31 on the substrate 10 at least partially overlap. As a result, the wide-angle light emitted by the first light-emitting element 21 in the first pixel opening 31 cannot be emitted from the first light-transmitting opening 41 corresponding thereto. When the display panel is in anti-peep mode, the first light-emitting element 21 emits light and the second light-emitting element 22 does not emit light. Since the wide-angle light emitted by the first light-emitting element 21 in the first pixel opening 31 cannot be emitted from the first light-transmitting opening 41 corresponding thereto, only the small-angle light and the normal-angle light of the light emitted by the first light-emitting element 21 in the first pixel opening 31 can be emitted from the first light-transmitting opening 41 corresponding thereto. Since the user's eyes usually observe the display panel from the normal viewing angle, the user can normally view the display screen of the display panel. When a user at a wide viewing angle position views the display panel, no wide viewing angle light is emitted from the light emitting surface of the display panel. The user at the wide viewing angle position cannot view the display image of the display panel, thereby achieving an anti-peeping function.

[0045] Continue to refer Figure 1 、 Figure 4-Figure 7 In some optional embodiments, the area of ​​the vertical projection of the first pixel opening 31 on the base substrate 10 is smaller than the area of ​​the vertical projection of the second pixel opening 32 on the base substrate 10 .

[0046] Specifically, the first pixel opening 31 and the second pixel opening 32 are both used to define a light-emitting area. The first light-emitting element 21 is at least partially located within the first pixel opening 31, i.e., the light-emitting area defined by the first pixel opening 31 is used to accommodate the first light-emitting element 21. The second light-emitting element 22 is at least partially located within the second pixel opening 32, i.e., the light-emitting area defined by the second pixel opening 32 is used to accommodate the second light-emitting element 22. The area of ​​the vertical projection of the first pixel opening 31 on the substrate 10 is smaller than the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10. i.e., the area of ​​the vertical projection of the first pixel opening 31 on the substrate 10 is smaller. Accordingly, the area of ​​the vertical projection of the first light-emitting element 21 on the substrate 10 is smaller, while the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10 is larger. Accordingly, the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10 is larger. When the spacing between the light-shielding layer 40 and the light-emitting element 20 is the same, the smaller the size of the light-emitting element 20, the smaller the viewing angle of the light emitted by the light-emitting element 20 that can be emitted from the corresponding light-transmitting opening. The vertical projection area of ​​the first pixel opening 31 on the substrate 10 is relatively small, thereby further reducing the viewing angle of the light emitted by the first light-emitting element 21 within the first pixel opening 31 that can be emitted through the corresponding first light-transmitting opening 41. When the display panel is in privacy protection mode, the first light-emitting element 21 emits light, while the second light-emitting element 22 does not. This further reduces the viewing angle of the light emitted by the first light-emitting element 21 within the first pixel opening 31 that can be emitted through the corresponding first light-transmitting opening 41, thereby improving the privacy protection effect.

[0047] The second pixel opening 32 has a larger area vertically projected onto the substrate 10, thereby further increasing the viewing angle of the light emitted by the second light-emitting element 22 within the second pixel opening 32 that can be emitted from the corresponding second light-transmitting opening 42. When the display panel is in sharing mode, the first light-emitting element 21 does not emit light, while the second light-emitting element 22 emits light. This further increases the viewing angle of the light emitted by the second light-emitting element 22 within the second pixel opening 32 that can be emitted from the corresponding second light-transmitting opening 42, thereby improving the sharing effect.

[0048] Continue to refer Figure 1 、 Figure 4-Figure 7 In some optional embodiments, the display panel includes a first pixel group P10, and the first pixel group P10 includes at least one first light emitting element 21;

[0049] The sum of the areas of the vertical projections of the first pixel openings 31 on the base substrate 10 in the first pixel group P10 is the same as the area of ​​the vertical projections of the second pixel openings 32 on the base substrate 10 .

[0050] Specifically, the sum of the areas of the vertical projections of the first pixel openings 31 on the substrate 10 in the first pixel group P10 is the same as the area of ​​the vertical projections of the second pixel openings 32 on the substrate 10. Accordingly, the sum of the areas of the vertical projections of the first light-emitting elements 21 on the substrate 10 in the first pixel group P10 is the same as the area of ​​the vertical projections of the second light-emitting elements 22 on the substrate 10. In anti-peep mode, the first light-emitting element 21 emits light, and the second light-emitting element 22 does not emit light. In sharing mode, the first light-emitting element 21 does not emit light, and the second light-emitting element 22 emits light. In the display panel, the number of first pixel groups P10 is the same as the number of second light-emitting elements 22, and the sum of the areas of the vertical projections of the first light-emitting elements 21 on the substrate 10 in the first pixel group P10 is the same as the area of ​​the vertical projections of the second light-emitting elements 22 on the substrate 10. As a result, the display panel has the same resolution in anti-peep mode and in sharing mode, improving the user experience.

[0051] Continue to refer Figure 1 、 Figure 4-Figure 7 In some optional embodiments, the first pixel group P10 includes at least two first light emitting elements 21 .

[0052] Specifically, the first pixel opening 31 and the second pixel opening 32 are both used to define the light-emitting area, the first light-emitting element 21 is at least partially located within the first pixel opening 31, that is, the light-emitting area defined by the first pixel opening 31 is used to set the first light-emitting element 21, and the second light-emitting element 22 is at least partially located within the second pixel opening 32, that is, the light-emitting area defined by the second pixel opening 32 is used to set the second light-emitting element 22. The area of ​​the vertical projection of the first pixel opening 31 on the substrate 10 is smaller than the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10, that is, the area of ​​the vertical projection of the first pixel opening 31 on the substrate 10 is smaller, and accordingly, the area of ​​the vertical projection of the first light-emitting element 21 on the substrate 10 is smaller, and the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10 is larger, that is, the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10 is larger, and the first pixel group P10 includes at least two first light-emitting elements 21, so that the sum of the areas of the vertical projections of the first pixel openings 31 on the substrate 10 in the first pixel group P10 is the same as the area of ​​the vertical projection of the second pixel openings 32 on the substrate 10.

[0053] Continue to refer Figure 1 、 Figure 4-Figure 7 In some optional embodiments, in the same first pixel group P10, two adjacent first light-emitting elements 21 arranged along the first direction X are symmetrically arranged along a first symmetry axis L1, and the first symmetry axis L1 extends along a second direction Y, wherein the first direction X and the second direction Y intersect. Optionally, the first direction X and the second direction Y are perpendicular to each other.

[0054] Specifically, in the same first pixel group P10, two adjacent first light-emitting elements 21 arranged along the first direction X are symmetrically arranged along the first symmetry axis L1, that is, in the same first pixel group P10, two adjacent first light-emitting elements 21 are designed to be axisymmetric, ensuring that the light intensity distribution within the first pixel group P10 is consistent, which is beneficial to improving the light uniformity of the corresponding area of ​​the first pixel group P10, thereby improving the display effect of the display panel in the anti-peep mode.

[0055] It should be noted that Figure 6 2 shows an arrangement structure of the first light emitting elements 21 in the first pixel group P10. In this embodiment, the first direction X and the second direction Y are not specifically limited. They are only used to clearly describe the positional relationship between two adjacent first light emitting elements 21 in the first pixel group P10. For example, refer to Figure 8 , Figure 8 This is a planar schematic diagram of another first pixel unit provided by the present disclosure. When the first pixel group P10 includes two first light-emitting elements 21, it can also be used. Figure 8 The arrangement described above will not be described in detail in this disclosure.

[0056] It should be noted that Figure 6 and Figure 8 exemplarily shows that the first pixel group P10 includes two first light-emitting elements 21. In other embodiments of the present disclosure, the first pixel group P10 may also include other numbers of first light-emitting elements 21. For example, referring to Figure 9 , Figure 9 FIG1 is a planar schematic diagram of another first pixel unit provided by the present disclosure. A first pixel group P10 includes four first light-emitting elements 21. In this case, in the same first pixel group P10, two adjacent first light-emitting elements 21 arranged along the first direction X are symmetrically arranged along a first symmetry axis L1, and two adjacent first light-emitting elements 21 arranged along the second direction Y are symmetrically arranged along a second symmetry axis L2, which extends along the first direction X. Of course, the first pixel group P10 can also be provided with other numbers of first light-emitting elements 21 according to actual needs, and this disclosure will not elaborate on them one by one here.

[0057] Optional, reference Figure 1-Figure 3 In the same first pixel group P10, the anodes of the first light-emitting elements 21 are connected, so that it is convenient to set each first light-emitting element 21 to be electrically connected to the same pixel circuit.

[0058] Figure 10 This is a schematic plan view of another first pixel unit provided by the present disclosure, with reference to Figure 1 、 Figure 4 、 Figure 5 and Figure 10,in, Figure 10 The structural diagram of the first pixel unit can be referred to Figure 7 In some optional embodiments, the first pixel group P10 includes a first light-emitting element 21 , and the vertical projection pattern of the first light-emitting element 21 on the base substrate 10 is a ring structure.

[0059] Specifically, the first pixel opening 31 and the second pixel opening 32 are both used to define the light-emitting area, the first light-emitting element 21 is at least partially located within the first pixel opening 31, that is, the light-emitting area defined by the first pixel opening 31 is used to set the first light-emitting element 21, and the second light-emitting element 22 is at least partially located within the second pixel opening 32, that is, the light-emitting area defined by the second pixel opening 32 is used to set the second light-emitting element 22. The area of ​​the vertical projection of the first pixel opening 31 on the substrate 10 is smaller than the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10, that is, the area of ​​the vertical projection of the first pixel opening 31 on the substrate 10 is smaller, and accordingly, the area of ​​the vertical projection of the first light-emitting element 21 on the substrate 10 is smaller, and the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10 is larger, that is, the area of ​​the vertical projection of the second pixel opening 32 on the substrate 10 is larger, and the first pixel group P10 includes a first light-emitting element 21, and the vertical projection pattern of the first light-emitting element 21 on the substrate 10 is a ring structure, so that the sum of the areas of the vertical projections of the first pixel openings 31 on the substrate 10 in the first pixel group P10 can be the same as the area of ​​the vertical projection of the second pixel openings 32 on the substrate 10.

[0060] Continue to refer Figure 1 、 Figure 4-Figure 7 In some optional embodiments, the width of the vertical projection pattern of each first light-transmitting opening 41 on the base substrate 10 along the third direction a in the first pixel group P10 is the same as the width of the vertical projection pattern of the second light-transmitting opening 42 on the base substrate along the third direction;

[0061] And / or, the length of the vertical projection pattern of each first light-transmitting opening 41 on the base substrate 10 along the fourth direction b in the first pixel group P10 is the same as the length of the vertical projection pattern of the second light-transmitting opening 42 on the base substrate 10 along the fourth direction b, and the third direction a and the fourth direction b intersect. Optionally, the third direction a and the fourth direction b are perpendicular.

[0062] Specifically, the width of the vertical projection pattern of each first light-transmitting opening 41 in the first pixel group P10 onto the substrate 10 along the third direction a is W1, and the width of the vertical projection pattern of the second light-transmitting opening 42 onto the substrate 10 along the third direction is W2, where W1 = W2. The length of the vertical projection pattern of each first light-transmitting opening 41 in the first pixel group P10 onto the substrate 10 along the fourth direction b is H1, and the length of the vertical projection pattern of the second light-transmitting opening 42 onto the substrate 10 along the fourth direction b is H2, where H1 = H2. That is, the outer contour formed by the vertical projection pattern of each first light-transmitting opening 41 in the first pixel group P10 onto the substrate 10 is similar to the outer contour of the vertical projection pattern of the second light-transmitting opening 42 onto the substrate 10. In anti-peep mode, the first light-emitting element 21 emits light, while the second light-emitting element 22 does not emit light. Light emitted by the first light-emitting element 21 can be emitted through its corresponding first light-transmitting opening 41. In sharing mode, the first light-emitting element 21 does not emit light, while the second light-emitting element 22 emits light. Light emitted by the second light-emitting element 22 can be emitted through the corresponding second light-transmitting opening 42. The outer contour formed by the vertical projection pattern of each first light-transmitting opening 41 in the first pixel group P10 on the base substrate 10 is similar to the outer contour of the vertical projection pattern of the second light-transmitting opening 42 on the base substrate 10. As a result, the display effect of the display panel in anti-peeping mode and sharing mode is similar, which can improve the user experience.

[0063] It should be noted that Figure 6 It is exemplarily shown that the third direction a is the same as the first direction X, and the fourth direction b is the same as the second direction Y. In other embodiments of the present disclosure, the third direction a may be different from the first direction X, and the fourth direction b may be different from the second direction Y, which will not be repeated in this disclosure.

[0066] The second pixel unit P2 includes at least two second light emitting elements 22 arranged along the fifth direction c. In the same second pixel unit P2, the light emitting colors of the second light emitting elements 22 are different.

Exemplarily, in the first pixel unit P1, the first light-emitting element 21 in one first pixel group P10 emits red light, the first light-emitting element 21 in one first pixel group P10 emits green light, and the first light-emitting element 21 in one first pixel group P10 emits blue light.

[0069] The second pixel unit P2 includes at least two second light emitting elements 22 arranged along the fifth direction c. In the same second pixel unit P2 , the second light emitting elements 22 emit light of different colors. Figure 4 The figure exemplarily shows that the second pixel unit P2 includes three second light-emitting elements 22 arranged along the fifth direction c. The three second light-emitting elements 22 are filled with different patterns to indicate that the second light-emitting elements 22 in the same second pixel unit P2 emit different colors. Exemplarily, in the second pixel unit P2, one second light-emitting element 22 emits red light, one second light-emitting element 22 emits green light, and one second light-emitting element 22 emits blue light.

[0072] Along the fifth direction c, the first pixel unit P1 and the second pixel unit P2 are alternately arranged, and along the sixth direction d, the first pixel unit P1 and the second pixel unit P2 are alternately arranged, so that the first pixel unit P1 and the second pixel unit P2 in the display panel can be evenly distributed.

In the sharing mode, the first light-emitting element 21 does not emit light, and the second light-emitting element 22 emits light. Therefore, a better display effect can be achieved in both the anti-peeping mode and the sharing mode. Moreover, the display effects in the anti-peeping mode and the sharing mode tend to be the same, which is conducive to improving the user experience.
