[0009] 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.

[0010] 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.

[0012] 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.

[0014] It should be understood that although the terms first, second, etc. may be used to describe directions, lens-like groups, sub-pixels, parts, etc. in the embodiments of the present application, these should not be limited to these terms. These terms are only used to distinguish directions, lens-like groups, sub-pixels, parts, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first direction may also be referred to as the second direction, and similarly, the second direction may also be referred to as the first direction. The applicant of this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0015] Figure 1 A schematic plan view of a display panel provided in an embodiment of the present application, Figure 2 A method provided in the embodiment of the present application Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0016] The present application embodiment provides a display panel 100, Figure 1 , Figure 2 As shown, the display panel 100 includes a substrate 10, and a plurality of film layers of the display panel 100 are prepared on one side of the substrate 10. The display panel 100 also includes a lens layer 20, and the lens layer 20 includes a lens group 20A, and the lens group 20A includes a plurality of lenses 20A1, and the lens 20A1 is away from the surface of the substrate 10 and convex toward the light-emitting surface of the display panel 100. Optionally, the lens 20A1 in the lens group 20A is a convex lens. Including a plurality of lenses in a lens group 20A is conducive to improving the light processing effect of the lens group 20A, and is conducive to avoiding the risk of a single light processing path when there is only one lens 20A1.

[0017] The display panel 100 further includes a light emitting layer 30, which is located between the lens layer 20 and the substrate 10, that is, the lens layer 20 is prepared on the side of the light emitting layer 30 facing the light emitting surface of the display panel 100, so that the light emitted from the light emitting layer 30 can pass through the lens layer 20. When the light emitted from the light emitting layer 30 passes through the lens layer 20, it passes through the multiple lenses 20A1 in the lens group 20A, and the multiple lenses 20A1 make the light produce a focusing effect.

[0018] In application scenarios such as driving, using the lens layer 20 in the display panel 100 indicated at the co-pilot position is beneficial for focusing the light emitted by the light-emitting layer 30 to avoid affecting the visual effect of the main driver when the light is relatively scattered.

[0019] The light emitting layer 30 includes a sub-pixel 30A, and in a direction perpendicular to the plane where the display panel 100 is located, at least one lens group 20A overlaps with the sub-pixel 30A. Optionally, one lens group covers one sub-pixel 30A. The extension length of the lens group 20A along the first direction X1 is set to be greater than the extension length of the sub-pixel 30A along the first direction X1, and the extension length of the lens group 20A along the second direction X2 is greater than the extension length of the sub-pixel 30A along the second direction X2, and the lens group 20A completely covers the sub-pixel 30A. The first direction X1 and the second direction X2 are both parallel to the plane where the display panel 100 is located, and the second direction X2 intersects with the first direction X1.

[0020] In the embodiment of the present application, the display panel 100 is provided with a lens layer 20, which is conducive to focusing the light emitted by the light-emitting layer 30 by using the lens layer 20, so that the display panel 100 has an anti-peeping effect at a certain angle, which is conducive to increasing the applicability in the anti-peeping field. In addition, multiple lenses 20A1 are provided in the same lens group 20A, which is conducive to using the combined effect of multiple lenses 20A1 to provide a possibility for reducing the height of a single lens 20A1; it is conducive to avoiding the risk that when the lens group 20A includes only one lens 20A1, in order to improve the processing effect of the lens 20A1 on light, the lens 20A1 is easily set higher, thereby generating a risk that is unfavorable to the lightness and thinness of the display panel 100. In addition, the multiple lenses 20A1 with smaller sizes distributed in the lens layer 20A are not only conducive to improving the lightness and thinness of the display panel when the anti-peeping function is included, but also conducive to improving the processing effect of the lens layer 20A on light, and on the basis of changing the light path, the uniformity of light distribution is improved as much as possible, the display effect of the display panel 100 is improved, and the user's visual experience is enhanced. Furthermore, in the embodiment of the present application, the lens group 20A is arranged to cover the sub-pixel 30A, which is beneficial for ensuring that all light emitted from the sub-pixel 30A toward the display panel 100 passes through the lens group 20A, thereby avoiding missing part of the light, and is beneficial for improving the processing effect of the light emitted by the sub-pixel 30A, thereby further improving the anti-peeping performance of the display panel 100.

[0021] Figure 3 A schematic plan view of a lens assembly provided for comparison and reference in an embodiment of the present application.

[0022] In one embodiment of the present application, continue to refer to Figure 1 , Figure 2 As shown, in the same lens group 20A, two adjacent lenses 20A1 at least partially overlap.

[0023] In order to better illustrate the technical solution of the present application, a lens schematic diagram is provided for comparison with the embodiment of the present application. Figure 3 . refer to Figure 3 As shown in FIG. (a), when the shape of the lens 20A1 is circular, although the multiple lenses 20A1 are arranged closely together, it is conceivable that there will be some gaps between the circular structures, and these gaps expose part of the light emitting layer 30, so there is a risk that the light emitted by part of the light emitting layer 30 cannot change the light path, which is not conducive to improving the anti-peeping effect of the display panel 100. Alternatively, continue to refer to Figure 3 As shown in FIG. (b), when the shape of the lens 20A1 is square, the surface of the square lens is convex toward the light-emitting surface of the display panel 100. When multiple lenses 20A1 are arranged closely together and there is no overlap between the lenses 20A1, the lens structure in the edge area between two adjacent lenses 20A1 is less convex, and the light processing effect corresponding to this part is poor. There is a risk that the light emitted from this edge area will be changed to a small extent, which is not conducive to improving the anti-peeping effect of the display panel 100.

[0024] In the embodiments of this application, continue to refer to Figure 1-Figure 2 As shown, setting two adjacent lenses 20A1 in the same lens group 20A to at least partially overlap is conducive to avoiding the presence of gaps between multiple adjacent lenses 20A1 in the prepared lens group 20A, thereby ensuring the coverage effect of the lens group 20A on the sub-pixel 30, ensuring that the light emitted by the sub-pixel 30 can pass through the lens group 20A before being emitted, which is conducive to improving the lens layer 20 to process the light more thoroughly. In addition, at least partially overlapping two adjacent lenses 20A1 is also conducive to avoiding the risk of poor light processing effect at the edge portion between the lens 20A1 and the lens 20A1, which is conducive to increasing the probability that the light can pass through the area where the light path change effect is more obvious, thereby improving the use effect of the lens group 20A, and thus improving the anti-peeping ability of the display panel 100.

[0025] Figure 4 Another embodiment provided in this application Figure 1 Schematic diagram of the cross section along the A-A' direction, Figure 5 Another embodiment provided in this application Figure 1Schematic diagram of the cross section along the A-A' direction, Figure 6 Another embodiment provided in this application Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0026] In one embodiment of the present application, Figure 1 , Figure 4-Figure 6 As shown, along the direction perpendicular to the plane where the display panel 100 is located, the maximum height of the portion of the lens 20A1 located in the lens layer 20 is H. Considering that the surface of the lens layer 20 facing the light-emitting layer 30 is parallel to the horizontal coordinate axis X and perpendicular to the vertical coordinate axis Y, the surface of the lens layer 20 facing the light-emitting layer 30 can be set as a horizontal plane, and the overlapping position coordinates of two adjacent lenses 20A1 are set as (0, D1), -1 H≤D1≤(4 / 5) H, so that the overlapping position coordinates of two adjacent lenses 20A1 are within a preset range, which is beneficial to improving the feasibility of the embodiment of the present application and the adaptability of adjusting the preparation of the lens 20A1, thereby improving the light processing effect of the lens group 20A and improving the anti-peeping effect of the display panel 100.

[0027] Alternatively, if Figure 4 As shown, the overlapping position coordinates of two adjacent lenses 20A1 are set to (0, -1 H), so that part of the lens 20A1 is located in the film layer between the lens layer 20 and the sub-pixel 30A in the light-emitting layer 30. Optionally, an encapsulation layer 40 is also included between the lens layer 20A1 and the sub-pixel 30A, and the encapsulation layer 40 can be used to flatten the surface of the sub-pixel 30A and protect the sub-pixel 30A from damage such as water and oxygen erosion. The encapsulation layer 40 has a certain thickness, and the light emitted by the sub-pixel 30A needs to pass through the encapsulation layer 40 before reaching the lens layer 20A1. Therefore, in the embodiment of the present application, the position where the two lenses 20A1 overlap is set to occupy part of the space of the encapsulation layer 40 under the lens layer 20, which is beneficial for at least part of the light to reach the lens 20A1 earlier and be processed, and is beneficial for reducing light loss and improving the display effect of the display panel 100.

[0028] Alternatively, if Figure 5 As shown, the overlapping position coordinates of two adjacent lenses 20A1 are set to (0, (1 / 2) H).

[0029] Alternatively, if Figure 6 As shown, the overlapping position coordinates of two adjacent lenses 20A1 are set to (0, (4 / 5) H), which helps to avoid the overlapping position of two adjacent lenses 20A1 being too high, causing the portion between the two adjacent lenses 20A1 to be close to a plane, thereby helping to avoid the position between the two adjacent lenses 20A1 having a good effect of changing the light path, thereby ensuring the light processing capability of the lens group 20A.

[0030] Figure 7 Another embodiment of the present application provides a Figure 1 Schematic diagram of the cross section along the A-A' direction.

[0031] In one embodiment of the present application, Figure 7 As shown, along the direction in which two adjacent lenses 20A1 are adjacent, the maximum width of the lens 20A1 is D, and the maximum width of the overlapping portion 20A2 of the two adjacent lenses 20A1 along the direction in which the two adjacent lenses 20A1 are adjacent is D2, 0≤D2≤(4 / 5) D.

[0032] In the embodiment of the present application, the width D2 of the overlapping portion 20A2 between two adjacent lenses 20A1 is set within a preset range, which is conducive to providing a feasible solution for the embodiment of the present application, and is also conducive to avoiding the existence of a gap between two adjacent lenses 20A1, thereby ensuring that the lens group 20A completely covers the sub-pixel 30A. In addition, it is conducive to the existence of an overlapping portion 20A2 between two adjacent lenses 20A, thereby improving the processing effect of the lens group 20A on light, so that the light emitted to the edge of the lens 20A1 can still have a relatively obvious effect of changing the light path, thereby improving the anti-peeping effect of the display panel 100.

[0033] Figure 8 A schematic plan view of a lens assembly provided in an embodiment of the present application, Fig. 9 A schematic plan view of another lens assembly provided in an embodiment of the present application.

[0034] In one embodiment of the present application, Figure 1 , Figure 8 , Fig. 9 As shown, the lens group 20A includes a plurality of lenses 20A1 arranged along the first direction X1 and / or along the second direction X2. The embodiment of the present application is described by taking one lens group 20A corresponding to one sub-pixel as an example.

[0035] Alternatively, if Figure 8As shown, the lens group 20A includes a plurality of lenses 20A1 arranged along the first direction X1. In combination with the above embodiments, it can be known that the extension lengths of the lens group 20A in the first direction X1 and the second direction X2 are both greater than the extension lengths of the sub-pixel 30 in the first direction X1 and the second direction X2. When the plurality of lenses 20A1 are arranged along the first direction X1, the diameter of the lens 20A1 in the second direction X2 can be set to be greater than the extension length of the sub-pixel 30A in the second direction X2.

[0036] Alternatively, if Fig. 9 As shown, the lens group 20A includes a plurality of lenses 20A1 arranged along the second direction X2. Combining the above content, it can be known that the diameter of the lens 20A1 in the first direction X1 can be set to be greater than the extension length of the sub-pixel 30 in the first direction X1.

[0037] Optionally, continue to refer to Figure 1 As shown, the lens group 20A includes a plurality of lenses 20A1 arranged along the first direction X1 and the second direction X2, which is conducive to more flexible adjustment of the preparation position of each lens 20A1 in the lens group 20A according to the size of the sub-pixel 30A, so that the lens group 20A better covers the sub-pixel 30.

[0038] In one embodiment of the present application, continue to refer to Figure 1 , Figure 2 As shown, the lens group 20A includes a first type lens group 20AA, the first type lens group 20AA includes a plurality of first type lenses 20AA1, the sub-pixel 30A includes a first type sub-pixel 30A1, and the first type lens group 20AA overlaps with the first type sub-pixel 30A1. In the embodiment of the present application, the first type lens group 20AA is configured to process the outgoing light of the first type sub-pixel 30A1, so that the optical path of the outgoing light of the first type sub-pixel 30A1 is changed by the first type lens 20AA1.

[0039] The surface of the first type lens 20AA1 away from the substrate 10 is set to be a curved surface in the first direction X1, and the surface of the first type lens 20AA1 away from the substrate 10 is also a curved surface in the second direction X2, so that the first type lens 20AA1 is a convex lens, and its surface has a focusing effect on light in multiple directions, which is beneficial to realize the anti-peeping function of the lens layer 20.

[0040] In one embodiment of the present application, reference Figure 2As shown, the same structure of multiple first-type lenses 20AA1 in the same first-type lens group 20AA is provided, which is conducive to unifying the processing effect of each first-type lens 20AA1 on light, improving the uniformity of light emitted from each position in the first-type lens group 20AA, and improving the display effect. In addition, the same structure of multiple first-type lenses 20AA1 in the same first-type lens group 20AA is conducive to reducing the difficulty of preparing the first-type lens group 20AA and improving the preparation efficiency of the first-type lens group 20AA.

[0041] Fig.10 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.11 A method provided in the embodiment of the present application Fig.10 Schematic diagram of the cross section along the B-B' direction.

[0042] In one embodiment of the present application, Fig.10 , Fig.11 As shown, at least some of the first-type lenses 20AA1 in the same first-type lens group 20AA have different structures, which is conducive to more flexible adjustment of the light emission path through the cooperation of the first-type lenses 20AA1 with different structures; and is conducive to achieving different processing effects on light emitted from different positions, more accurately adjusting the light emission path, thereby improving the light processing effect of the lens layer 20. Optionally, as Fig.10 As shown, at least some of the first type lenses 20AA1 in the same first type lens group 20AA have different diameters.

[0043] In one embodiment of the present application, continue to refer to Fig.10 , Fig.11 As shown, in the same first-type lens group 20AA, the diameter of the first-type lens 20AA1 close to the edge of the first-type sub-pixel 30A1 is larger than the diameter of the first-type lens 20AA1 far from the edge of the first-type sub-pixel 30A1. When the first-type sub-pixel 30A1 emits light, some of the light has a large emission angle, which is not conducive to achieving anti-peeping of the display panel 100.

[0044] In the embodiment of the present application, the diameter of the first type lens 20AA1 near the edge of the first type sub-pixel 30A1 is set to be larger than the diameter of the first type lens 20AA1 away from the edge of the first type sub-pixel 30A1, which is conducive to improving the coverage of the edge position of the first type sub-pixel 30A1 by the first type lens group 20AA, ensuring that light with a larger exit angle can also pass through the first type lens 20AA1, and changing the optical path to reduce the exit angle of the light. In addition, the diameter of the first type lens 20AA1 near the edge of the first type sub-pixel 30A1 is larger than the diameter of the first type lens 20AA1 away from the edge of the first type sub-pixel 30A1, which is conducive to improving the ability of the first type lens 20AA1 near the edge of the first type sub-pixel 30A1 to focus light, thereby improving the effect of the first type lens group 20AA focusing light.

[0045] Fig.12 A method provided in the embodiment of the present application Fig.10 Schematic diagram of the cross section along the B-B' direction.

[0046] In one embodiment of the present application, Fig.10 , Fig.12 As shown, in the same first-type lens group 20AA, the thickness of the first-type lens 20AA1 close to the edge of the first-type sub-pixel 30A1 in the direction perpendicular to the plane where the display panel 100 is located is greater than the thickness of the first-type lens 20AA1 away from the edge of the first-type sub-pixel 30A1 in the direction perpendicular to the plane where the display panel 100 is located.

[0047] In the embodiment of the present application, the first-type lens 20AA1 disposed near the edge of the first-type sub-pixel 30A1 has a greater thickness in a direction perpendicular to the plane of the display panel 100, which is beneficial for the first-type lens 20AA1 to focus the light, so that the first-type lens 20AA1 located at the edge of the first-type sub-pixel 30A1 can also block part of the light with a larger exit angle, so that the light with a larger exit angle passes through the first-type lens 20AA1 located at the edge of the first-type sub-pixel 30A1 again, thereby focusing it a second time.

[0048] Fig.13 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.14 A method provided in the embodiment of the present application Fig.13 Schematic diagram of the cross section along the C-C' direction.

[0049] In one embodiment of the present application, Fig.13 , Fig.14As shown, the plurality of first-type sub-pixels 30A1 include a first-type first-color sub-pixel 30A11, a first-type second-color sub-pixel 30A12, and a first-type third-color sub-pixel 30A13. Optionally, the first-type first-color sub-pixel 30A11, the first-type second-color sub-pixel 30A12, and the first-type third-color sub-pixel 30A13 proposed in the embodiment of the present application are red sub-pixels, green sub-pixels, and blue sub-pixels, respectively.

[0050] The first type lens group 20AA at least partially overlapping with the first type first color sub-pixel 30A11 includes a plurality of first type first lenses 20AA11, the first type lens group 20AA at least partially overlapping with the first type second color sub-pixel 30A12 includes a plurality of first type second lenses 20AA12, and the first type lens group 20AA at least partially overlapping with the first type third color sub-pixel 30A13 includes a plurality of first type third lenses 20AA13. The emitted light of the three color sub-pixels can all be emitted after passing through the lens, which is conducive to ensuring the overall anti-peeping effect of the display panel 100.

[0051] In the embodiment of the present application, the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 are arranged to have the same structure, which is conducive to reducing the difficulty of preparing the lens 20A1 in the lens layer 20 and improving the preparation efficiency of multiple lenses 20A1. In addition, the lens types covering sub-pixels of different colors are arranged to have the same structure, which is conducive to improving the light path processing effect of the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 on the sub-pixels 30A1 of three colors, respectively, and improving the display uniformity when the display panel 100 includes the lens layer 20, thereby improving the display effect of the display panel 100.

[0052] Fig.15 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.16 A method provided in the embodiment of the present application Fig.15 Schematic diagram of the cross section along the D-D' direction.

[0053] In one embodiment of the present application, Fig.15 , Fig.16As shown, the plurality of first-class sub-pixels 30A1 include a first-class first-color sub-pixel 30A11, a first-class second-color sub-pixel 30A12, and a first-class third-color sub-pixel 30A13. Optionally, the first-class first-color sub-pixel 30A11, the first-class second-color sub-pixel 30A12, and the first-class third-color sub-pixel 30A13 proposed in the embodiment of the present application are red sub-pixels, green sub-pixels, and blue sub-pixels, respectively. The first-class lens group 20AA at least partially overlapping with the first-class first-color sub-pixel 30A11 includes a plurality of first-class first lenses 20AA11, the first-class lens group 20AA at least partially overlapping with the first-class second-color sub-pixel 30A12 includes a plurality of first-class second lenses 20AA12, and the first-class lens group 20AA at least partially overlapping with the first-class third-color sub-pixel 30A13 includes a plurality of first-class third lenses 20AA13.

[0054] In the embodiment of the present application, the structures of the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 are different. It can be understood that the light emitting areas of the first type of first color sub-pixel 30A11, the first type of second color sub-pixel 30A12, and the first type of third color sub-pixel 30A13 in the display panel 100 can be different. When preparing the lens 20A1 on the sub-pixel 30A11 of the corresponding color, the structures of the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 can be adaptively arranged according to the size of the sub-pixel 30A1 of different colors, so as to improve the light path processing effect of the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 on the first type of first color sub-pixel 30A11, the first type of second color sub-pixel 30A12, and the first type of third color sub-pixel 30A13.

[0055] Alternatively, if Fig.15 , Fig.16 As shown, the light emitting area of ​​the first type third color sub-pixel 30A13 among the first type first color sub-pixel 30A11, the first type second color sub-pixel 30A12, and the first type third color sub-pixel 30A13 is larger, and the diameter of the first type third lens 20AA13 can be adaptively increased.

Fig.18 A method provided in the embodiment of the present application Fig.17 Schematic diagram of the cross section along the E-E' direction, Fig.19 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig. 20 A kind of Fig.19 Schematic diagram of the cross section along the F-F' direction.

[0057] In one embodiment of the present application, Figure 17-Figure 20 As shown, the lens group 20A in the display panel 100 further includes a second type lens group 20AB, and the second type lens group 20AB includes at least one second type lens 20AB1.

[0058] Continue to refer Fig.17 , Fig.19 As shown, the sub-pixel 30A further includes a second type of sub-pixel 30A2, and the second type of lens group 20AB overlaps with the second type of sub-pixel 30A2.

[0059] Alternatively, if Fig.17 , Fig.18 As shown, the lens group 20A included in the display panel 100 is a second type lens group 20AB, and the second type lens group 20AB covers the second type sub-pixel 30A2.

[0060] Alternatively, if Fig.19 , Fig. 20 As shown, the display panel 100 includes a first type lens group 20AA and a second type lens group 20AB, and the first type lens group 20AA covers the first type sub-pixel 30A1, and the second type sub-pixel 20AB covers the second type sub-pixel 30A2.

[0061] In the embodiments of the present application, Fig.17 As shown, the lens group 20A in the display panel 100 also includes a second type lens group 20AB, and the second type lens 20AB1 in the second type lens group 20AB includes at least a first portion 20AB11, and the first portion 20AB11 extends along the first direction X1 away from the surface of the substrate 10, which is conducive to setting the display panel 100 to include different types of lenses 20A, thereby facilitating the display panel 100 to change the optical path of light in different usage scenarios. And at least the first portion 20AB11 included in the second type lens 20AB1 extends along the first direction X1 away from the surface of the substrate, so that the light emitted from the light emitting layer in the first direction X1 may not have its optical path changed, which is conducive to making the second type lens 20AB1 suitable for scenes that process light in a targeted manner.

[0062] Or, if Fig.19As shown, the display panel 100 includes a first type lens group 20A1 and a second type lens group 20B, and the second type lens 20AB1 in the second type lens group 20AB includes at least a first portion 20AB11, and the first portion 20AB11 extends away from the surface of the substrate 10 along the first direction X1. The display panel 100 also includes a first type sub-pixel 30A1 and a second type sub-pixel 30A2, which is conducive to using different lens groups to make the light emitted by different sub-pixels 30A in the display panel 100 obtain different light path processing effects, which is conducive to making the display panel 100 suitable for more application scenarios. For example, when the display panel 100 needs a higher anti-peeping requirement, the first type sub-pixel 30A1 is used for display, and at this time, the first type lens group 20A1 can produce a good focusing effect on the light emitted by the first type sub-pixel 30A1. When the display panel 100 is not strict with the anti-peeping condition, the second type of sub-pixel 30A2 can be used for display. At this time, the second type of lens group 20B can selectively focus the light emitted by the second type of sub-pixel 30B, so that the anti-peeping direction of the display panel 100 is adjustable.

[0063] Fig.21 A schematic plan view of another display panel provided in an embodiment of the present application.

[0064] In one embodiment of the present application, Fig.21 As shown, the first portion 20AB11 of the second type of lens 20AB1 extends away from the surface of the substrate 10 along the second direction X2. Optionally, the first portion 20AB11 of the second type of lens 20AB1 extends away from the surface of the substrate 10 along the first direction X1 and extends along the second direction X2, which is conducive to making the surface of the second type of lens 20AB1 away from the substrate 10 a plane. The embodiment of the present application is described by taking the display panel 100 including the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 as an example.

[0065] It can be seen from the above embodiments that the surface of the first-type sub-pixel 30A1 covers the first-type lens group 20AA, and the surface of the first-type lens 20AA1 in the first-type lens group 20AA is a curved surface extending along the first direction X1 and the second direction X2, so that when the first-type sub-pixel 30A1 is displayed, the light emitted by the first-type sub-pixel 30A1 can be focused, so that when the display panel 100 needs to be in anti-peep mode, the first-type sub-pixel 30A1 can be selected to work.

[0066] In the embodiment of the present application, the display panel 100 is provided to further include a second type of sub-pixel 30A2, and the surface of the second type of lens 20AB1 covered by the surface of the second type of sub-pixel 30A2 at least includes a first portion 20AB11 whose surface extends in a straight line along the first direction X1 and in a straight line along the second direction X2, which is conducive to making the surface of the second type of sub-pixel 30A2 also covered with a lens, but the optical path of the light emitted by the second type of sub-pixel 30A2 can be selectively changed. The technical solution of the present application is conducive to making the display panel 100 also suitable for non-peep-proof or targeted peeping directions, at which time the second type of sub-pixel 30A2 can be set to work. In addition, after the surface of the first type of sub-pixel 30A1 is provided in the display panel 100 and covered with a lens, a lens is also prepared on the surface of the second type of sub-pixel 30A2 accordingly, which is conducive to improving the structural regularity of the display panel 100, and when the first type of sub-pixel 20A and the second type of sub-pixel 30A2 work at the same time, it is conducive to reducing the difference in the light output brightness of the two, thereby improving the display effect of the display panel 100.

[0067] In one embodiment of the present application, continue to refer to Fig.17 , Fig.19 As shown, the surface of the first part 20AB11 of the second type lens 20AB1 away from the substrate 10 is a curved surface in the second direction X2. In addition, the curved surface of the surface of the first part 20AB11 of the second type lens 20AB1 away from the substrate 10 in the second direction X2 is convex toward the light emitting surface of the display panel 100. In combination with the fact that the surface of the first part 20AB11 away from the substrate 10 extends in the first direction X1, it can be known that the first part 20AB11 of the second type lens 20AB1 can focus the light emitted from the second type sub-pixel 30A2 toward the second direction X2.

[0068] In the embodiment of the present application, the surface of the first part 20AB11 of the second type lens 20AB1 away from the substrate 10 is a curved surface in the second direction X2, which is conducive to the second type lens 20AB1 having the ability to change the optical path of the light emitted by the second type sub-pixel 30A2 toward the second direction X2, so that when the second type sub-pixel 30A2 of the display panel 100 is working, the light scattered in the second direction X2 is gathered as much as possible, which is conducive to the display panel 100 being used in a targeted anti-peeping direction. For example, when the display panel 100 is used in the field of automobile display, the display panel 100 is located at a position close to the front windshield of the car in the second direction X2. When the display panel 100 emits light, part of the light will be projected onto the windshield, which is likely to cause the risk of affecting the driver's observation of the road conditions. Therefore, the embodiment of the present application uses the surface of the second type sub-pixel 30A2 to cover the second type lens 20AB1, because the light emitted by the second type sub-pixel 30A2 is prevented from being projected onto the front windshield of the car in the second direction X2, thereby improving the clarity of the driver's observation of the road conditions and improving driving safety.

[0069] Fig. 22 A method provided in the embodiment of the present application Fig.19 Projection view of the second type of lens in .

[0070] In one embodiment of the present application, Fig.19 , Fig. 22 As shown, the projection area of ​​the first part 20AB11 of the second type of lens 20AB1 in the first direction X1 is different from the projection area of ​​the first part 20AB11 in the second direction X2. In combination with the above embodiments, it can be known that the first part 20AB11 extends along the first direction X1, and the curved surface extending along the second direction X2 is a surface, and the second type of lens 20AB1 can be set to a columnar structure with a curved surface away from the substrate 10.

[0071] like Fig. 22 As shown in FIG. (a) of the figure, the projection shape of the first part 20AB11 of the second type of lens 20AB1 in the first direction X1 is a fan shape, such as Fig. 22 As shown in FIG. 5( b ), the projection shape of the first portion 20AB11 of the second type of lens 20AB1 in the second direction X2 is a rectangle.

[0072] Fig.23 A schematic plan view of another display panel provided in an embodiment of the present application is shown in FIG. Fig.24 A method provided in the embodiment of the present application Fig.23 Schematic diagram of the cross section along the G-G' direction.

[0073] In one embodiment of the present application, Fig.23 , Fig.24As shown, the second type of lens 20AB1 also includes a second part 20AB12. Optionally, the first part 20AB11 and the second part 20AB12 of the second type of lens 20AB1 are continuous structures. Along the first direction X1, the second part 20AB12 is located on a side of the first part 20AB11 close to at least one edge of the second type of lens 20AB1. In other words, the second part 20AB12 of the second type of lens 20AB1 is located at the edge of the second type of lens 20AB1.

[0074] In the embodiment of the present application, the surface of the second portion 20AB12 away from the substrate 10 is set to be a curved surface in the first direction X1, which is conducive to the light emitted from the second portion 20AB12 toward the edge of the second sub-pixel 30A2 having the ability to change its optical path, and is conducive to reducing the scattered light of the edge portion of the second sub-pixel 30A2 in the first direction X1, so that when the second portion 20AB12 is used to reach the first sub-pixel 30A1 and the second sub-pixel 30A2 in the display panel 100, both can have an anti-peeping effect in the first direction X1. In addition, when the display panel 100 includes the first sub-pixel 30A1 and the second sub-pixel 30A2, optionally, the first sub-pixel 30A1 and the second sub-pixel 30A2 are adjacent in the first direction X1, which is conducive to avoiding the emission of the second sub-pixel 30A2 from affecting the emission of the first sub-pixel 30A1, and is conducive to avoiding the light crosstalk between the first sub-pixel 30A1 and the second sub-pixel 30A2, thereby improving the display effect of the display panel 100.

[0076] In one embodiment of the present application, Figure 25-27As shown, the second type lens group 20AB includes at least two second type lenses 20AB1, and the second type lenses 20AB1 in the same second type lens group 20AB are arranged along the first direction X1, and / or, the second type lenses 20AB1 in the same second type lens group 20AB are arranged along the second direction X2. The embodiment of the present application is described by taking a second type lens group 20AB covering a second type sub-pixel 30A2 as an example. In the embodiment of the present application, the number of the second type lenses 20AB1 in the second type lens group 20AB is set to be greater than or equal to 2, which is conducive to increasing the number of the second type lenses 20AB1 in the same second type lens group 20AB, thereby helping to reduce the size of a single second type lens 20AB1, thereby avoiding the risk of the second type lens group 20AB being set to be large in height, thereby increasing the thickness of the display panel 100. And the provision of multiple second type lenses 20AB1 is conducive to providing conditions for flexibly changing the optical path of the light through the cooperation of multiple second type lenses 20AB1.

[0077] In one embodiment of the present application, reference Figure 25-27 As shown, the structures of multiple second type lenses 20AB1 in the same second type lens group 20AB are the same, which is conducive to reducing the difficulty in preparing multiple second type lenses 20AB1, thereby improving the work efficiency of preparing the second type lenses 20AB1, and further improving the preparation efficiency of the display panel 100.

[0078] Fig.28 A method provided in the embodiment of the present application Fig.19 Schematic diagram of the cross section along the H-H' direction.

[0079] In one embodiment of the present application, Fig.19 , 28 As shown, at least some of the second type lenses 20AB1 in the same second type lens group 20AB have different structures. Optionally, the height of the second type lenses 20AB1 located at the edge of the second type lens group 20AB is greater than the height of the second type lenses 20AB1 located in the middle of the second type lens group 20AB.

[0080] In the embodiment of the present application, at least some of the second-type lenses 20AB1 in the same second-type lens group 20AB have different structures, which is beneficial to improving the structural diversity of the second-type lenses 20AB1. The second-type lenses 20AB1 with different structures have different focusing capabilities for light. Therefore, the outgoing light of the second-type sub-pixel 30A2 processed by the second-type lenses 20AB1 with different structures is beneficial to improving the accuracy of the second-type lens group 20AB in changing the optical path of the outgoing light of the second-type sub-pixel 30A2, thereby improving the anti-peeping performance of the display panel 100.

[0081] Fig.29A flow chart of an operating mode of a display panel provided in an embodiment of the present application.

[0082] In one embodiment of the present application, Fig.29 As shown, the display panel 100 includes a first working mode M1 and a second working mode M2. When the display panel 100 is in the first working mode M1, the first sub-pixel 30A1 is turned on and the second sub-pixel 30A2 is turned off. When the display panel 100 is in the second working mode M2, both the first sub-pixel 30A1 and the second sub-pixel 30A2 are turned on. In the embodiment of the present application, the first working module M1 is an anti-peeping mode and the second working mode M2 ​​is a non-anti-peeping mode as an example for explanation. When the display panel 100 is applied to the automotive field, the display panel 100 can be applied to a co-pilot display screen. Optionally, when the display panel 100 is working in the first working mode M1, the corresponding car is in the process of driving. From the perspective of the driver, it is not easy to receive the light emitted by the first sub-pixel 30A1. When the display panel 100 is working in the second working mode M2, the corresponding car is in a non-driving process. From the perspective of the driver, it is easier to receive the emitted light of the display panel 100.

[0083] In the embodiment of the present application, when the display panel 100 is set in the first working mode M1, the first type of sub-pixel 30A1 is controlled to be turned on. At this time, the light emitted by the first type of sub-pixel 30A1 can be focused by the first type of lens 20AA, so that the display content of the display panel 100 can be viewed more clearly by the co-driver, and the person in the main driver's seat is not easy to observe the display content, which is conducive to reducing the impact of the display panel 100 on the main driver when it is working, thereby helping to reduce the risk of distracting the main driver's attention and improve the driving safety of the car. When the display panel 100 is set in the second working mode M2, the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 are controlled to be turned on, which is conducive to increasing the number of pixels in the display panel 100 that are in operation, thereby improving the display effect of the display panel 100 and improving the viewing effect of the person in the main driver's seat at a wide viewing angle.

[0084] Fig.30 A flowchart of another operating mode of a display panel provided in an embodiment of the present application.

[0085] In one embodiment of the present application, Fig.30 As shown, the display panel 100 includes a first working mode M1 and a second working mode M2. When the display panel 100 is in the first working mode M1, the first sub-pixel 30A1 is turned on and the second sub-pixel 30A2 is turned off. When the display panel 100 is in the second working mode M2, the first sub-pixel 30A1 is turned off and the second sub-pixel 30A2 is turned on.

[0086] In the embodiment of the present application, the first working module M1 is in anti-peeping mode and the second working mode M2 ​​is in non-peeping mode as an example for explanation. When the display panel 100 is applied to the automotive field, the display panel 100 can be applied to the co-pilot display screen. Optionally, when the display panel 100 works in the first working mode M1, the corresponding car is in the process of driving, and from the driver's perspective, it is not easy to receive the light emitted by the first type of sub-pixel 30A1. When the display panel 100 works in the second working mode M2, the corresponding car is in a non-driving process. From the driver's perspective, the emitted light of the display panel 100 can be easily received.

[0087] In the embodiment of the present application, when the display panel 100 is set to be in the first working mode M1, the first type of sub-pixel 30A1 is controlled to be turned on. At this time, the light emitted by the first type of sub-pixel 30A1 can be focused by the first type of lens 20AA, so that the display content of the display panel 100 can be viewed more clearly by the co-driver, and the person in the main driving seat is not easy to observe the display content, which is conducive to reducing the impact of the display panel 100 on the main driver when it is working, thereby helping to reduce the risk of distracting the main driver's attention and improve the driving safety of the car. When the display panel 100 is set to be in the second working mode M2, the first type of sub-pixel 30A1 is controlled to be turned off and the second type of sub-pixel 30A2 is turned on, which is conducive to turning on the second type of sub-pixel 30A2 with a weaker anti-peeping effect on the main driving position, and is conducive to allowing the person in the main driving seat to view the display panel 100 normally; and, setting only one type of sub-pixel 30A to be turned on in a working mode is conducive to reducing the working energy consumption of the display panel 100.

[0088] Fig.31 A schematic diagram of a pixel circuit provided in an embodiment of the present application.

[0089] In one embodiment of the present application, the display panel 100 also includes a pixel circuit 50, which is located on the side of the light-emitting layer 30 facing the substrate 10. The pixel circuit 50 is used to generate a light-emitting driving current and transmit the light-emitting driving current to the sub-pixel 30A located in the light-emitting layer 30, thereby driving the sub-pixel 30A to emit light.

[0090] like Fig.31 As shown, the same pixel circuit 50 is electrically connected to the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, which is conducive to enabling the pixel circuit 50 to simultaneously have the ability to control the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, which is conducive to reducing the number of pixel circuits 50, thereby improving the thinness of the display panel 100. Optionally, the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 electrically connected to the same pixel circuit 50 have the same luminous color.

[0091] The pixel circuit 50 includes a first light-emitting control module 50A, a second light-emitting control module 50B, and a third light-emitting control module 50C. The control end of the first light-emitting control module 50A is electrically connected to the first light-emitting signal line E1, the first end is electrically connected to the first power supply voltage PVDD, and the second end is electrically connected to the first end of the second light-emitting control module 50C. When the first light-emitting signal line E1 transmits a valid signal, the pixel circuit 50 works in the light-emitting stage. At this time, the first power supply voltage PVDD drives the pixel circuit 50 to work, and transmits the first power supply voltage PVDD to the first light-emitting control module 50A. The first light-emitting control module 50A transmits the received first power supply voltage PVDD to the driving transistor Md, and the driving transistor Md generates a light-emitting driving current. Then, the light-emitting driving current generated by the driving transistor Md flows to the first type of sub-pixel 30A1 or the second type of sub-pixel 30A2.

[0092] The control end of the second light emitting control module 50C in the pixel circuit 50 is also electrically connected to the first light emitting signal line E1, and the second end is electrically connected to the first type of sub-pixel 30A1. The control end of the third light emitting control module 50C is electrically connected to the second light emitting signal line E2, the first end is electrically connected to the second end of the first light emitting control module 50A, and the second end is electrically connected to the second type of sub-pixel 30A2.

[0093] In the embodiment of the present application, when the display panel 100 is in the first working mode M1, the first light-emitting signal line E1 transmits a valid signal to control the first light-emitting control module 50A and the second light-emitting control module 50B to turn on, and the second light-emitting signal line E2 transmits an ineffective signal to control the third light-emitting control module 50C to turn off. When the display panel 100 is in the second working mode M1, the first light-emitting signal line E1 transmits a valid signal and the second light-emitting signal line E2 transmits a valid signal, and the first light-emitting control module 50A, the second light-emitting control module 50B, and the third light-emitting control module 50C are all turned on. This is conducive to realizing that the display panel 100 controls the first type of sub-pixel 30A1 to turn on and the second type of sub-pixel 30A2 to turn off when the display panel 100 is in the first working mode M1, and realizes that the display panel 100 controls the first type of sub-pixel 30A and the second type of sub-pixel 30B to turn on when the display panel 100 is in the second working mode M2.

[0094] In addition, if Fig.31 As shown, the pixel circuit 50 provided in the embodiment of the present application further includes: The data writing module 50D is used to receive the data voltage Vdata and transmit the data voltage Vdata to the driving transistor Md. The value of the data voltage Vdata is related to the brightness of the first sub-pixel 30A1 and the second sub-pixel 30A2.

[0095] The first reset module 50E is used to reset the gate of the driving transistor Md before the driving transistor Md receives the data voltage, and transmit the first reset voltage Vref1 to the gate of the driving transistor Md to ensure the accuracy of the light emitting driving current generated by the driving transistor Md.

[0096] The threshold writing module 50F is used to compensate the threshold voltage of the driving transistor Md to the gate of the driving transistor Md.

[0097] The second reset module 50G is used to reset the first type sub-pixel 30A1 before it receives the light-emitting driving current, and transmit the second reset voltage Vref2 to the first electrode of the first type sub-pixel 30A1 to ensure the accuracy of the light-emitting brightness of the first type sub-pixel 30A1.

In addition, since the arrangement uniformity of the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 is further improved, the display effect of the display panel 100 is improved.

[0110] Fig.35 A schematic plan view of another display panel provided in an embodiment of the present application.

[0111] In one embodiment of the present application, Fig.35 As shown, the light emitting layer 30 includes first type pixel units A30 and second type pixel units B30 alternately arranged along the first direction X1 and the second direction X2. The first type pixel unit A30 includes a plurality of first type sub-pixels 30A1 of different colors, and the second type pixel unit B30 includes a plurality of second type sub-pixels 30B of different colors.

[0112] In the embodiment of the present application, it is proposed that the first-type pixel single unit A30 and the second-type pixel unit B30 are alternately arranged, which is beneficial to improving the arrangement diversity of the first-type sub-pixel 30A1 and the second-type sub-pixel 30B, and is beneficial to improving the applicability of the technical solution of the present application, and there are more ways to prepare the first-type sub-pixel 30A1 and the second-type sub-pixel 30A2 in different application scenarios of the display panel 100.

[0113] In one embodiment of the present application, continue to refer to Fig.34 , Fig.35As shown, the first type of sub-pixel 30A1 includes a first type of third color sub-pixel 30A13 and the second type of sub-pixel 30A2 includes a second type of third color sub-pixel 30A23. The first type of third color sub-pixel 30A13 and the second type of third color sub-pixel 30A23 are alternately arranged along the second direction X2.

[0114] In the embodiment of the present application, the spacing between the first type of third color sub-pixels 30A13 and the second type of third color sub-pixels 30A23 adjacent to each other in the second direction X2 is the same, which is conducive to improving the uniform distribution of the first type of third color sub-pixels 30A13 and the second type of third color sub-pixels 30A23 prepared on the display panel 100, and is conducive to improving the display effect when the first type of third color sub-pixels 30A13 and the second type of third color sub-pixels 30A23 are both working.

The first type of third color sub-pixel 30A13 and the second type of third color sub-pixel 30A23 are alternately arranged along the second direction X2.

[0117] In the embodiment of the present application, the spacings between at least some of the first-type third-color sub-pixels 30A13 and the second-type third-color sub-pixels 30A23 adjacent in the second direction X2 are different, which is beneficial for optimizing the color uniformity of the entire display panel 100 by adjusting the spacings between the first-type third-color sub-pixels 30A13 and the second-type third-color sub-pixels 30B3. For example, when the first-type third-color sub-pixels 30A13 and the second-type third-color sub-pixels 30A23 are both blue sub-pixels, since excessively concentrated blue light may cause discomfort to the eyes, increasing the spacing between the blue sub-pixels can reduce the concentration effect of blue light, make the color distribution more uniform, and thus reduce visual fatigue.

[0118] In one embodiment of the present application, the lens 20A is a plano-convex lens or a bi-convex lens, which is helpful to provide relevant technical personnel with a variety of optional lens 20A structures and improve the applicability of the embodiment of the present application.

In addition, multiple lenses 20A1 are provided in the same lens group 20A, which is conducive to using the combined effect of multiple lenses 20A1 to provide a possibility for reducing the height of a single lens 20A1; it is conducive to avoiding the risk of setting the lens 20A1 higher to improve the light processing effect of the lens 20A1 when the lens group 20A includes only one lens 20A1, thereby generating a risk that is unfavorable to the lightness and thinness of the display panel 100. In addition, the multiple lenses 20A1 with smaller sizes distributed in the lens layer 20A are not only conducive to improving the lightness and thinness of the display panel 100 when the anti-peeping function is included, but also conducive to improving the light processing effect of the lens layer 20A, and improving the uniformity of the light distribution as much as possible on the basis of changing the light path, improving the display effect of the display panel 100, and enhancing the user's visual experience. Furthermore, in the embodiment of the present application, the lens group 20A is arranged to cover the sub-pixel 30A, which is beneficial for ensuring that all light emitted from the sub-pixel 30A toward the display panel 100 passes through the lens group 20A, thereby avoiding missing part of the light, and is beneficial for improving the processing effect of the light emitted by the sub-pixel 30A, thereby further improving the anti-peeping performance of the display panel 100.
