[0042] The features and exemplary embodiments of each aspect of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than limiting the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0043] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without more limitations, the elements defined by the statement "including..." do not exclude the existence of additional identical elements in the process, method, article or device including the said elements.

[0044] In some usage scenarios, the display panel 100 needs to have different display images for users at different positions. Taking in-vehicle display as an example, the driver and the co-driver are located at different positions of the in-vehicle display. During vehicle driving, the driver may need to query road condition information through the in-vehicle display, while the co-driver may hope to watch some entertainment programs through the in-vehicle display. At this time, how to achieve "multiple functions on one screen" to meet the actual needs of different users has become one of the research directions of many manufacturers.

[0045] In view of the above problems, in a first aspect, please refer to Figure 1 FIG. 4, an embodiment of the present application provides a display panel 100. The display panel 100 includes a substrate 11, a device layer 12, a light-shielding portion 50, and a first light-shielding layer 40. The device layer 12 is disposed on one side of the substrate 11. The device layer 12 includes a plurality of sub-pixels 20. The plurality of sub-pixels 20 includes a first type of sub-pixel 21 and a second type of sub-pixel 22. The first type of sub-pixel 21 is used to display a first perspective image, and the second type of sub-pixel 22 is used to display a second perspective image. The light-shielding portion 50 is disposed on the side of the device layer 12 away from the substrate 11. Along the direction perpendicular to the plane where the substrate 11 is located, the light-shielding portion 50 is located between adjacent sub-pixels 20. The first light-shielding layer 40 is disposed on the side of the light-shielding portion 50 away from the substrate 11. The first light-shielding layer 40 includes a plurality of first light-shielding openings 41. Along the direction perpendicular to the plane where the substrate 11 is located, the first light-shielding openings 41 at least partially overlap with the first type of sub-pixel 21 and do not overlap with the second type of sub-pixel 22.

[0046] The display panel 100 further includes a first group 31. The first group 31 includes a plurality of sub-pixels 20 and a light-shielding portion 50. The plurality of first groups 31 are arranged in a first direction X and a second direction Y. The first group 31 includes a first type of sub-pixel 21 and a second type of sub-pixel 22. The first direction X and the second direction Y are both parallel to the plane where the substrate 11 is located and intersect with each other. Among them, in a single first group 31, all the second type of sub-pixels 22 are located on one side of all the first type of sub-pixels 21 along the first direction X, and at least a part of the light-shielding portion 50 is located on the side of the second type of sub-pixel 22 away from the first type of sub-pixel 21 along the first direction X.

[0047] The substrate 11 mainly plays a role of supporting and carrying. Other film layer structures and device structures are sequentially stacked on the substrate 11. The so-called stacked setting mentioned here means that other film layer structures and device structures are sequentially arranged along the thickness direction Z of the substrate 11. Among them, the thickness direction Z of the substrate 11 is usually consistent with the thickness direction Z of other film layers and perpendicular to the plane where the substrate 11 is located. For the convenience of understanding, the thickness direction Z and the direction perpendicular to the plane where the substrate 11 is located are indicated by the same direction in the embodiments of the present application.

[0048] The device layer 12 is the main film layer structure in the display panel 100 for realizing the light-emitting function. The device layer 12 is disposed on one side of the substrate 11 along the thickness direction Z. The device layer 12 includes a plurality of sub-pixels 20. Taking the display panel 100 as an organic light-emitting display panel 100 as an example, the device layer 12 includes an anode layer, a light-emitting layer, and a cathode layer stacked in a direction away from the substrate 11. The sub-pixel 20 includes an anode located in the anode layer, a light-emitting portion located in the light-emitting layer, and a cathode located in the cathode layer. The cathode and the anode jointly drive and control the light emission of the light-emitting portion. Among them, Figure 3 The anode and the light-emitting portion in the sub-pixel 20 are shown, while the cathode is not shown.

[0049] The plurality of sub-pixels 20 include a first-type sub-pixel 21 and a second-type sub-pixel 22. The first-type sub-pixel 21 is used to display a first-view image, and the second-type sub-pixel 22 is used to display a second-view image, that is, the first-type sub-pixel 21 and the second-type sub-pixel 22 are respectively used to display image frames of different viewing angles. For the convenience of understanding, in the following embodiments of the present application, it is taken as an example that the first-type sub-pixel 21 is used to display a front-view image frame and the second-type sub-pixel 22 is used to display a left-view image frame. Among them, Figure 4a The corresponding sub-pixel arrangement mode when the user observes the first-view image is shown. Figure 4b The corresponding sub-pixel arrangement mode when the user observes the second-view image is shown.

[0050] Specifically, for the light rays emitted from the plurality of first-type sub-pixels 21 at multiple angles, only the light rays emitted in the forward direction can leave the display panel 100, so that the user directly facing the display panel 100 can observe the image frame formed by the plurality of first-type sub-pixels 21, while users at other positions cannot observe the image frame formed by the plurality of first-type sub-pixels 21. For the light rays emitted from the plurality of second-type sub-pixels 22 at multiple angles, only the light rays emitted obliquely to the left can leave the display panel 100, so that the user on the left side of the display panel 100 can observe the image frame formed by the plurality of second-type sub-pixels 22, while users at other positions cannot observe the image frame formed by the plurality of second-type sub-pixels 22.

[0051] The light-shielding portion 50 and the first light-shielding layer 40 both include light-shielding materials and are located on the light-emitting surface side of the sub-pixel 20. For the light-shielding portion 50, in the direction perpendicular to the plane where the substrate 11 is located, the light-shielding portion 50 is located between adjacent sub-pixels 20. That is, on any plane in the direction perpendicular to the plane where the substrate 11 is located, the orthographic projection of the light-shielding portion 50 is located between the orthographic projections of adjacent sub-pixels 20. In other words, the orthographic projection of the light-shielding portion 50 on the substrate 11 is located between the orthographic projections of adjacent sub-pixels 20 on the substrate 11. Due to this positional relationship between the light-shielding portion 50 and the sub-pixel 20, part of the oblique light emitted by the sub-pixel 20 near the light-shielding portion 50 will propagate to the light-shielding portion 50 and be absorbed and blocked by the light-shielding portion 50.

[0052] For the first light-shielding layer 40, the first light-shielding layer 40 is provided with first light-shielding openings 41. The first light-shielding openings 41 penetrate the first light-shielding layer 40 in the thickness direction Z. There is a light-shielding material between adjacent first light-shielding openings 41. The light that propagates to the first light-shielding openings 41 can exit the display panel 100, while the light that propagates to the adjacent first light-shielding openings 41 is absorbed and blocked by the light-shielding material.

[0053] The light-shielding portion 50 and the first light-shielding layer 40 cooperate with each other to achieve a double screening of the emitted light. Specifically, since the first light-shielding layer 40 is located on the side of the light-shielding portion 50 away from the substrate 11, the light-shielding portion 50 can preliminarily screen the light emitted by the sub-pixel 20. Part of the light will propagate to the light-shielding portion 50 and be absorbed and blocked, while other parts of the light can propagate to the first light-shielding layer 40. At this time, the first light-shielding layer 40 can perform a secondary screening on the light. The light that propagates to the first light-shielding openings 41 can exit the display panel 100, while other light is absorbed and blocked by the first light-shielding layer 40.

[0054] In addition to the above structure, the display panel 100 further includes a first group 31. The first group 31 includes a plurality of sub-pixels 20 and a light-shielding portion 50. The number of the first groups 31 is multiple. The types of sub-pixels 20, the arrangement manner between the plurality of sub-pixels 20, and the relative positional relationship between the sub-pixel 20 and the light-shielding portion 50 in different first groups 31 remain the same or present a certain specific relationship. The multiple first groups 31 are arranged in the first direction X and the second direction Y. The first direction X, the second direction Y, and the thickness direction Z intersect pairwise. Further optionally, the first direction X, the second direction Y, and the thickness direction Z are pairwise perpendicular.

[0055] It should be noted that the display panel 100 may only include a plurality of first groups 31. In this case, the plurality of first groups 31 are arranged adjacent to each other in the first direction X and the second direction Y. That is, there are no other sub-pixels 20 between the two first groups 31 that are closest to each other in the first direction X, and there are no other sub-pixels 20 between the two first groups 31 that are closest to each other in the second direction Y. Alternatively, the display panel 100 may further include a second group 32 or even more groups. In this case, there may be a second group 32 or other groups between the two first groups 31 that are closest to each other. Among them, Figure 1 FIG. Figure 1 shows a case where the display panel 100 only includes the first group 31.

[0056] The first group 31 includes first-type sub-pixels 21 and second-type sub-pixels 22. In a single first group 31, all the second-type sub-pixels 22 are located on one side of all the first-type sub-pixels 21 along the first direction X. Taking the second-type sub-pixels 22 for displaying a left-view image as an example and combining Figures 1 to 3 it, the first direction X is the horizontal direction, and all the second-type sub-pixels 22 in a single first group 31 are located on the right side of all the first-type sub-pixels 21. Among them, the "all first-type sub-pixels 21" mentioned here refers to: all the first-type sub-pixels 21 located in a single first group 31. When there is only one first-type sub-pixel 21 in a single first group 31, all the first-type sub-pixels 21 refer to this one first-type sub-pixel 21. When there are multiple first-type sub-pixels 21 in a single first group 31, all the first-type sub-pixels 21 refer to these multiple first-type sub-pixels 21. The "all second-type sub-pixels 22" mentioned in the embodiments of the present application is the same by analogy, and the embodiments of the present application will not elaborate further.

[0057] It should be noted that when a single first group 31 includes multiple first-type sub-pixels 21, the embodiments of the present application do not limit the specific number, arrangement mode, and emission color of the multiple first-type sub-pixels 21 in a single first group 31, and the second-type sub-pixels 22 are the same by analogy. Exemplarily. The multiple first-type sub-pixels 21 in a single first group 31 may be arranged at intervals along the first direction X, or may also be arranged at intervals along the second direction Y. Further, at least one of the number, emission color, and arrangement mode of the first-type sub-pixels 21 and the second-type sub-pixels 22 in a single first group 31 may be the same, or may also be different, and the embodiments of the present application do not limit this either.

[0058] In a single first group 31, at least part of the light-shielding portion 50 is located on the side of the second-type sub-pixels 22 away from the first-type sub-pixels 21 along the first direction X. Through the mutual cooperation of the light-shielding portion 50 and the first light-shielding layer 40, the display panel 100 can correspondingly have different display images at different viewing angles.

[0059] Combined Figure 1 Specifically, with reference to FIGS. 3 and 4, for the first type of sub-pixels 21, in a direction perpendicular to the plane where the substrate 11 is located, the first light-shielding opening 41 at least partially overlaps with the first type of sub-pixels 21, and the light-shielding portion 50 does not overlap with the first type of sub-pixels 21. Therefore, the front-view light emitted by the first type of sub-pixels 21 will not propagate to the light-shielding portion 50 and can exit the display panel 100 through the first light-shielding opening 41.

[0060] Furthermore, the right-view light obliquely emitted to the right by the first type of sub-pixels 21 will propagate to the light-shielding portion 50 within the same first group 31 and be absorbed and blocked by the light-shielding portion 50, while the left-view light obliquely emitted to the left by the first type of sub-pixels 21 will propagate to the light-shielding portion 50 of the adjacent first group 31 and be absorbed and blocked by the light-shielding portion 50. Therefore, the first type of sub-pixels 21 can display a front-view image, but cannot display a left-view image and a right-view image.

[0061] For the second type of sub-pixels 22, the left-view light obliquely emitted to the left by the second type of sub-pixels 22 can exit the display panel 100 through the nearest first light-shielding opening 41. The right-view light obliquely emitted to the right by the second type of sub-pixels 22 will propagate to the light-shielding portion 50 within the same first group 31 and be absorbed and blocked by the light-shielding portion 50.

[0062] Furthermore, in a direction perpendicular to the plane where the substrate 11 is located, the first light-shielding opening 41 does not overlap with the second type of sub-pixels 22, and the front-view light emitted by the second type of sub-pixels 22 will propagate between the adjacent first light-shielding openings 41 and be absorbed and blocked. Therefore, the first type of sub-pixels 21 can display a left-view image, but cannot display a front-view image and a right-view image.

[0063] In summary, the first type of sub-pixels 21 can display a front-view image, but cannot display a left-view image and a right-view image. The second type of sub-pixels 22 can display a left-view image, but cannot display a front-view image and a right-view image. Thus, the front-view image corresponding to the display panel 100 is only controlled and displayed by a plurality of the first type of sub-pixels 21, and the second type of sub-pixels 22 will not affect the front-view image. The left-view image corresponding to the display panel 100 is only controlled and displayed by a plurality of the second type of sub-pixels 22, and the first type of sub-pixels 21 will not affect the left-view image. On this basis, by separately driving and controlling the first type of sub-pixels 21 and the second type of sub-pixels 22, the independent display of the front-view image and the left-view image can be realized, so that the front-view image and the left-view image can display different images at the same time, meeting the different image requirements of different users at different viewing angles, thereby achieving the display effect of "one screen with multiple functions".

[0064] It should be noted that, based on adjusting the positional relationship between the first-type sub-pixels 21 and the second-type sub-pixels 22, a light-shielding portion 50 is added in the display panel 100, and the size and position of the first light-shielding opening 41 are adjusted, so as to achieve independent control of the images at different viewing angles. On this basis, the embodiments of the present application may not adjust the structures of the first-type sub-pixels 21 and the second-type sub-pixels 22, that is, the first-type sub-pixels 21 and the second-type sub-pixels 22 of the same color may include the same light-emitting material and the same film layer composition form. In view of this, the first-type sub-pixels 21 and the second-type sub-pixels 22 of the same color can be formed together in the same process, thereby simplifying the manufacturing process of the device layer 12.

[0065] In addition, when a single first group 31 includes multiple first-type sub-pixels 21, as Figure 1 shown, multiple first-type sub-pixels 21 within a single first group 31 may be correspondingly arranged with the same first light-shielding opening 41, or as Figure 5 shown, multiple first-type sub-pixels 21 within a single first group 31 are respectively correspondingly arranged with multiple first light-shielding openings 41. The embodiments of the present application do not limit this.

[0066] In the embodiments of the present application, by adjusting the relative positional relationship between the first-type sub-pixels 21, the second-type sub-pixels 22, and the light-shielding portion 50 within a single first group 31, and defining the opening size and position of the first light-shielding opening 41 in the first light-shielding layer 40, the first-type sub-pixels 21 and the second-type sub-pixels 22 can respectively display corresponding images at different viewing angles without changing the structures of the first-type sub-pixels 21 and the second-type sub-pixels 22 themselves, and without interfering with the images at other viewing angles. In this way, the images of the display panel 100 at different viewing angles can display different image information. In this way, the "multiple functions on one screen" display effect of the display panel 100 is achieved, and independent display of the images at different viewing angles is realized.

[0067] In some embodiments, please refer to Figure 6 , the display panel 100 further includes a second group 32. The second group 32 includes multiple sub-pixels 20 and a light-shielding portion 50. The second group 32 includes first-type sub-pixels 21 and second-type sub-pixels 22. The light-emitting colors of the first-type sub-pixels 21 located in the first group 31 and the second group 32 are different from each other, and the light-emitting colors of the second-type sub-pixels 22 located in the first group 31 and the second group 32 are different from each other.

[0068] In a single second group 32, all the second-type sub-pixels 22 are located on one side of all the first-type sub-pixels 21 in the first direction X, and at least a part of the light-shielding portion 50 is located on the side of the second-type sub-pixels 22 away from the first-type sub-pixels 21 in the first direction X. Among them, the multiple first groups 31 and the multiple second groups 32 are arranged alternately in the first direction X; and / or, the multiple first groups 31 and the multiple second groups 32 are arranged alternately in the second direction Y.

[0069] In addition to the first group 31, the display panel 100 further includes a second group 32. Similar to the first group 31, the second group 32 also includes first-type sub-pixels 21, second-type sub-pixels 22, and a light-shielding portion 50, and the relative positions among the first-type pixels, the second-type sub-pixels 22, and the light-shielding portion 50 within a single second group 32 are consistent with those of the first group 31. On this basis, the first-type sub-pixels 21 located within the second group 32 are only used to display the front-view image, and the second-type sub-pixels 22 located within the second group 32 are only used to display the left-view image.

[0070] The emission colors of the first-type sub-pixels 21 within the first group 31 are different from those of the first-type sub-pixels 21 within the second group 32, that is, the emission colors of each of the first-type sub-pixels 21 within the first group 31 are not the same as those of each of the first-type sub-pixels 21 within the second group 32. Similarly, the emission colors of the second-type sub-pixels 22 within the first group 31 are different from those of the second-type sub-pixels 22 within the second group 32, that is, the emission colors of each of the second-type sub-pixels 22 within the first group 31 are not the same as those of each of the second-type sub-pixels 22 within the second group 32.

[0071] Under this design, through the cooperative emission of the first-type sub-pixels 21 within the first group 31 and the first-type sub-pixels 21 within the second group 32, a colorful display effect of the front-view image can be achieved, and through the cooperative emission of the second-type sub-pixels 22 within the first group 31 and the second-type sub-pixels 22 within the second group 32, a colorful display effect of the left-view image can be achieved.

[0072] It should be noted that the specific emission colors and quantities of the first-type sub-pixels 21 and the second-type sub-pixels 22 in the first group 31 and the second group 32 are not limited in the embodiments of the present application. The quantity of the first-type sub-pixels 21 in the first group 31 may be the same as or different from the quantity of the first-type sub-pixels 21 in the second group 32. The emission colors of at least some of the first-type sub-pixels 21 in the first group 31 may be the same as or different from the emission colors of at least some of the second-type sub-pixels 22 in the second group 32. Similarly, the emission colors of at least some of the second-type sub-pixels 22 in the first group 31 may be the same as or different from the emission colors of at least some of the first-type sub-pixels 21 in the second group 32.

[0073] The multiple first groups 31 and the multiple second groups 32 can have various arrangement manners. For example, Figure 6 as shown, the multiple first groups 31 and the multiple second groups 32 can be alternately arranged and set only in the first direction X, that is, there is a second group 32 between two closest first groups 31 in the first direction X, and there is a first group 31 between two closest second groups 32 in the first direction X. Or, as Figure 7 shown, the multiple first groups 31 and the multiple second groups 32 can be alternately arranged and set only in the second direction Y, that is, there is a second group 32 between two closest first groups 31 in the second direction Y, and there is a first group 31 between two closest second groups 32 in the second direction Y. Or, as Figure 8 shown, the multiple first groups 31 and the multiple second groups 32 can be alternately arranged and set both in the first direction X and in the second direction Y.

[0074] It should be noted that only the first group 31 and the second group 32 may exist in the display panel 100, or the display panel 100 may further include a third group 33 or even more groups in addition to the first group 31 and the second group 32, which is not limited in the embodiments of the present application. When only the first group 31 and the second group 32 are included in the display panel 100, the closest first group 31 and the second group 32 can be adjacently arranged, that is, there are no other sub-pixels 20 therebetween.

[0075] In the embodiments of the present application, in addition to the first group 31, the display panel 100 further includes a second group 32. The emission colors of the first-type sub-pixels 21 in the first group 31 and the second group 32 are different from each other, and the emission colors of the second-type sub-pixels 22 in both are different from each other. In this way, by means of the combined emission of the first group 31 and the second group 32, a colorful display effect corresponding to different viewing-angle images of the display panel 100 can be achieved, thereby improving the user's viewing experience. Further, in the embodiments of the present application, the relative positions of multiple first groups 31 and multiple second groups 32 are also restricted. The multiple first groups 31 and multiple second groups 32 are arranged alternately at least in one direction, so as to reduce the risk that the first-type sub-pixels 21 with the same emission color are overly concentrated in a local area, and the risk that the second-type sub-pixels 22 with the same emission color are overly concentrated in a local area, and improve the display uniformity of the display panel 100 in different areas.

[0076] In some embodiments, the emission colors of the first-type sub-pixels 21 and the second-type sub-pixels 22 in the first group 31 are different from each other, and the emission colors of the first-type sub-pixels 21 and the second-type sub-pixels 22 in the second group 32 are different from each other. The emission colors of the first-type sub-pixels 21 in the first group 31 and the second-type sub-pixels 22 in the second group 32 are the same, and the emission colors of the second-type sub-pixels 22 in the first group 31 and the first-type sub-pixels 21 in the second group 32 are the same.

[0077] For the convenience of understanding, in the embodiments of the present application, Figure 6 and Figure 9 The structure shown will be taken as an example for description. The first group 31 and the second group 32 are arranged alternately in the first direction X. For the first group 31, the distance between the first-type sub-pixels 21 and the second-type sub-pixels 22 in the same first group 31 is often relatively short. For adjacent first group 31 and second group 32, a light-shielding portion 50 needs to be provided between the second-type sub-pixels 22 in the first group 31 and the first-type sub-pixels 21 in the second group 32. Therefore, in order to meet the preparation requirements of the light-shielding portion 50, a certain distance needs to be provided between them in the first direction X. And between the first-type sub-pixels 21 in the first group 31 and the second-type sub-pixels 22 in the second group 32, not only the light-shielding portion 50 is provided, but also the second-type sub-pixels 22 in the first group 31 and the first-type sub-pixels 21 in the second group 32 exist. Therefore, there is also a relatively large distance between them in the first direction X.

[0078] Combined with the foregoing content, since the first-type sub-pixels 21 and the second-type sub-pixels 22 can have the same film layer composition method and material composition method, the first-type sub-pixels 21 and the second-type sub-pixels 22 with the same emission color can be prepared and formed together in the same process.

[0079] In view of this, in the embodiments of the present application, the first-type sub-pixels 21 and the second-type sub-pixels 22 located in the first group 31 are set to have different emission colors, and the first-type sub-pixels 21 and the second-type sub-pixels 22 located in the second group 32 are set to have different emission colors, so that the first-type sub-pixels 21 and the second-type sub-pixels 22 located in the first group 31 can be separately formed in different processes. Compared with the solution in which the first-type sub-pixels 21 and the second-type sub-pixels 22 in the first group 31 have the same emission color and are formed together in the same process, this design can improve the problem of excessive difficulty in preparing the photomask caused by the too-close distance between the mask openings corresponding to the sub-pixels 20 with the same emission color.

[0080] Furthermore, in the embodiments of the present application, the first-type sub-pixels 21 located in the first group 31 and the second-type sub-pixels 22 located in the second group 32 are set to have the same emission color, and the second-type sub-pixels 22 located in the first group 31 and the first-type sub-pixels 21 located in the second group 32 are set to have the same emission color, so that the first-type sub-pixels 21 located in the first group 31 and the second-type sub-pixels 22 located in the second group 32 can be formed together in the same process, and the second-type sub-pixels 22 located in the first group 31 and the first-type sub-pixels 21 located in the second group 32 can be formed together in the same process, thereby simplifying the manufacturing process of the device layer 12. At the same time, this design enables there to be at least one light-shielding portion 50 between the sub-pixels 20 with the same emission color. Therefore, in order to meet the preparation requirements of the light-shielding portion 50, a relatively large distance is required between the sub-pixels 20 with the same emission color, thereby reducing the problem of excessive difficulty in preparing the photomask caused by the too-close distance between the corresponding mask openings, and having strong practicability.

[0081] In some embodiments, as Figure 6 and Figure 9 shown, the multiple first-type sub-pixels 21 include a first sub-pixel 21a, a second sub-pixel 21b, and a third sub-pixel 21c with different colors, and the multiple second-type sub-pixels 22 include a fourth sub-pixel 22a, a fifth sub-pixel 22b, and a sixth sub-pixel 22c with different colors. The first group 31 includes the first sub-pixel 21a and the second sub-pixel 21b arranged in the second direction Y, and the fourth sub-pixel 22a located on the same side of the first sub-pixel 21a and the second sub-pixel 21b along the first direction X.

[0082] The second group 32 includes a fifth sub-pixel 22b and a sixth sub-pixel 22c arranged in the second direction Y, and a third sub-pixel 21c located on the same side of the fifth sub-pixel 22b and the sixth sub-pixel 22c along the first direction X. Among them, the first sub-pixel 21a has the same emission color as the fifth sub-pixel 22b, the second sub-pixel 21b has the same emission color as the sixth sub-pixel 22c, and the fourth sub-pixel 22a has the same emission color as the third sub-pixel 21c.

[0083] For the sake of easy understanding, in the embodiments of the present application, Figure 9 taking the structure shown as an example for description, the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c are used to realize the display of the front-view image, and the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c are used to realize the display of the left-view image. Among them, both the first sub-pixel 21a and the fifth sub-pixel 22b are red sub-pixels 20, both the second sub-pixel 21b and the sixth sub-pixel 22c are green sub-pixels 20, and both the fourth sub-pixel 22a and the third sub-pixel 21c are blue sub-pixels 20.

[0084] On this basis, the first sub-pixel 21a and the second sub-pixel 21b in the first group 31 and the third sub-pixel 21c in the second group 32 together form a single pixel unit corresponding to the front-view image, and the fourth sub-pixel 22a in the first group 31 and the fifth sub-pixel 22b and the sixth sub-pixel 22c in the second group 32 together form a single pixel unit corresponding to the left-view image. Herein, the "pixel unit" mentioned refers to: the smallest repeating unit for forming a specific display image.

[0085] In the embodiments of the present application, by providing the first sub-pixel 21a and the second sub-pixel 21b in the first group 31, providing the third sub-pixel 21c in the second group 32, and arranging the first group 31 and the second group 32 alternately in at least one direction, the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c in the first group 31 and the second group 32 with the closest distance together form a pixel unit corresponding to the front-view image. By adding different proportions of the three emission colors of the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c, a variety of colored lights are generated, so as to cover most of the colors that can be perceived by the user's eyesight and meet the multi-color display needs of the user when viewing from the front view.

[0086] Similarly, in the embodiment of the present application, the fourth sub-pixel 22a is provided in the first group 31, the fifth sub-pixel 22b and the sixth sub-pixel 22c are provided in the second group 32, and the first group 31 and the second group 32 are arranged alternately in at least one direction. Thus, the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c in the first group 31 and the second group 32 with the closest distance jointly form the pixel unit corresponding to the left viewing angle picture. By adding different proportions of the three emission colors of the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c, a variety of color lights are generated, so as to cover most of the colors that the user's vision can perceive, and meet the multi-color display requirements of the user when viewing from the left viewing angle.

[0087] Further, in the embodiment of the present application, the first sub-pixel 21a and the second sub-pixel 21b in the first group 31 are arranged in the second direction Y, and the third sub-pixel 21c and the light-shielding portion 50 are arranged on one side of the first sub-pixel 21a and the second sub-pixel 21b in the first direction X, so as to reasonably design the sizes of the first group 31 in the first direction X and the second direction Y, reduce the risk of the size of the first group 31 being too large in one of the first direction X and the second direction Y, and improve the rationality of the pixel arrangement.

[0088] Similarly, in the embodiment of the present application, the fifth sub-pixel 22b and the sixth sub-pixel 22c in the second group 32 are arranged in the second direction Y, and the fourth sub-pixel 22a and the light-shielding portion 50 are arranged on both sides of the fifth sub-pixel 22b and the sixth sub-pixel 22c in the first direction X, so as to reasonably design the sizes of the second group 32 in the first direction X and the second direction Y, reduce the risk of the size of the second group 32 being too large in one of the first direction X and the second direction Y, and improve the rationality of the pixel arrangement.

[0089] In some embodiments, as Figure 6 and Figure 9 shown, a plurality of first groups 31 and a plurality of second groups 32 are arranged alternately in the first direction X. In the first group 31 and the second group 32 adjacent in the first direction X, the first sub-pixel 21a and the fifth sub-pixel 22b are arranged in the first direction X, the second sub-pixel 21b and the sixth sub-pixel 22c are arranged in the first direction X, and both the fourth sub-pixel 22a and the third sub-pixel 21c are located between the first sub-pixel 21a and the fifth sub-pixel 22b.

[0090] It should be noted that, as Figure 6 shown, a plurality of first groups 31 and a plurality of second groups 32 may be alternately distributed only in the first direction X, while a plurality of first groups 31 are adjacent in the second direction Y, and a plurality of second groups 32 are adjacent in the second direction Y. Or as Figure 7As shown, multiple first groups 31 and multiple second groups 32 can also be alternately arranged in the first direction X and also alternately arranged in the second direction Y.

[0091] Multiple first groups 31 and multiple second groups 32 are alternately arranged in the first direction X, and there are no other sub-pixels 20 between the first group 31 and the second group 32 that are closest in the first direction X. In this way, in addition to being able to block the light emitted by the fourth sub-pixel 22a and obliquely emitted to the right, the light-shielding portion 50 located in the first group 31 can also be used to block the light emitted by the third sub-pixel 21c and obliquely emitted to the left. Similarly, in addition to being able to block the light emitted by the fifth sub-pixel 22b and the sixth sub-pixel 22c and obliquely emitted to the right, the light-shielding portion 50 located in the second group 32 can also be used to block the light emitted by the first sub-pixel 21a and the second sub-pixel 21b and obliquely emitted to the left, so as to meet the independent display needs of different viewing angles.

[0092] In addition, in the embodiment of the present application, the first sub-pixel 21a and the fifth sub-pixel 22b having the same emission color in adjacent first group 31 and second group 32 are arranged in the first direction X, and the second sub-pixel 21b and the sixth sub-pixel 22c having the same emission color are arranged in the first direction X, so that the multiple first-type sub-pixels 21 in the first group 31 and the multiple second-type sub-pixels 22 in the second group 32 have the same layout, improving the regularity of pixel arrangement and reducing the design and preparation difficulty of the sub-pixels 20 in the display panel 100.

[0093] Furthermore, in the embodiment of the present application, the third sub-pixel 21c and the fourth sub-pixel 22a having the same emission color in adjacent first group 31 and second group 32 are both arranged between the first sub-pixel 21a and the fifth sub-pixel 22b, so that the second-type sub-pixels 22 in the first group 31 and the second group 32 are all located on the same side of the first-type sub-pixels 21, so as to meet the independent display needs corresponding to different viewing angles.

[0094] In some embodiments, please refer to Figure 7 、 Figure 8 and Figure 10 , multiple first groups 31 and multiple second groups 32 are alternately arranged in the second direction Y. In the first group 31 and the second group 32 that are adjacent in the second direction Y, the third sub-pixel 21c, the first sub-pixel 21a, and the second sub-pixel 21b are arranged in sequence in the second direction Y, and the fifth sub-pixel 22b, the sixth sub-pixel 22c, and the fourth sub-pixel 22a are arranged in sequence in the second direction Y.

[0095] Such as Figure 7As shown, multiple first groups 31 and multiple second groups 32 can be arranged alternately only in the second direction Y. In this case, multiple first groups 31 are arranged adjacent to each other in the first direction X, and multiple second groups 32 are arranged adjacent to each other in the first direction X. In this way, the light-shielding portion 50 in the first group 31 is used to block the light emitted by the fourth sub-pixel 22a and obliquely emitted to the right, and is also used to block the light emitted by the first sub-pixel 21a and the second sub-pixel 21b and obliquely emitted to the left. The light-shielding portion 50 in the second group 32 is used to block the light emitted by the fifth sub-pixel 22b and the sixth sub-pixel 22c and obliquely emitted to the right, and is also used to block the light emitted by the third sub-pixel 21c and obliquely emitted to the left, so as to meet the independent display requirements corresponding to different viewing angles.

[0096] As Figure 8 shown, multiple first groups 31 and multiple second groups 32 can also be arranged alternately in the first direction X and also arranged alternately in the second direction Y. In this case, in addition to blocking the light emitted by the fourth sub-pixel 22a and obliquely emitted to the right, the light-shielding portion 50 in the first group 31 is also used to block the light emitted by the third sub-pixel 21c and obliquely emitted to the left. The light-shielding portion 50 in the second group 32 is used to block the light emitted by the fifth sub-pixel 22b and the sixth sub-pixel 22c and obliquely emitted to the right, and is also used to block the light emitted by the first sub-pixel 21a and the second sub-pixel 21b and obliquely emitted to the left, so as to meet the independent display requirements corresponding to different viewing angles.

[0097] Multiple first groups 31 and multiple second groups 32 are arranged alternately in the second direction Y, and there are no other sub-pixels 20 between the first group 31 and the second group 32 that are closest in the second direction Y. Under this design, the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c for displaying the front-view image can be arranged in the second direction Y, and the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c for displaying the left-view image can be arranged in the second direction Y.

[0098] Further, multiple first-type sub-pixels 21 in the first group 31 are arranged in the second direction Y, multiple second-type sub-pixels 22 in the second group 32 are arranged in the second direction Y, and multiple first-type sub-pixels 21 in the first group 31 and multiple second-type sub-pixels 22 in the second group 32 have the same arrangement manner, so that the sub-pixels 20 of the same color are arranged more regularly, thereby reducing the design difficulty and manufacturing difficulty of the sub-pixels 20 in the display panel 100.

[0099] In some embodiments, please refer to Figure 11, a plurality of sub-pixels 20 and a light-shielding portion 50 together form a third group 33. The third group 33 includes first-type sub-pixels 21 and second-type sub-pixels 22. The plurality of first groups 31, the plurality of second groups 32, and the third group 33 are alternately arranged in the second direction Y. The plurality of first-type sub-pixels 21 include a first sub-pixel 21a, a second sub-pixel 21b, and a third sub-pixel 21c with different emission colors. The plurality of second-type sub-pixels 22 include a fourth sub-pixel 22a, a fifth sub-pixel 22b, and a sixth sub-pixel 22c with different emission colors. The first group 31 includes the first sub-pixel 21a and the fourth sub-pixel 22a. The second group 32 includes the second sub-pixel 21b and the fifth sub-pixel 22b. The third group 33 includes the third sub-pixel 21c and the sixth sub-pixel 22c. Among them, in the first group 31, the second group 32, and the third group 33 adjacent in the second direction Y, the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c are arranged in the second direction Y, and the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c are arranged in the second direction Y.

[0100] In addition to the first group 31 and the second group 32, the display panel 100 may further include a third group 33. Similar to the first group 31 and the second group 32, the third group 33 also includes first-type sub-pixels 21, second-type sub-pixels 22, and a light-shielding portion 50. And the relative positions among the first-type pixels, the second-type sub-pixels 22, and the light-shielding portion 50 within a single third group 33 are the same as those of the first group 31. On this basis, the first-type sub-pixels 21 located in the third group 33 are only used to display the front-view image, and the second-type sub-pixels 22 located in the third group 33 are only used to display the left-view image.

[0101] The first group 31 includes the first sub-pixel 21a and the fourth sub-pixel 22a. The second group 32 includes the second sub-pixel 21b and the fifth sub-pixel 22b. The third group 33 includes the third sub-pixel 21c and the sixth sub-pixel 22c. In other words, the emission colors of the first-type sub-pixels 21 in the first group 31, the second group 32, and the third group 33 are different from each other, and the emission colors of the second-type sub-pixels 22 in the first group 31, the second group 32, and the third group 33 are different from each other. Among them, the first sub-pixel 21a and the fourth sub-pixel 22a may have the same emission color, or may have different emission colors. The same applies to the two sub-pixels 20 in the second group 32 and the two sub-pixels 20 in the third group 33. The embodiments of the present application do not limit this.

[0102] Furthermore, in the embodiments of the present application, the multiple first groups 31, the multiple second groups 32, and the third group 33 are alternately arranged in the second direction Y. The first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c are sequentially arranged in the second direction Y to form a pixel unit for displaying a front-view image. The fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c are sequentially arranged in the second direction Y to form a pixel unit for displaying a left-view image. This design makes the arrangement of the multiple sub-pixels 20 in the pixel unit for displaying the front-view image more compact, thereby helping to improve the display effect of the front-view image. Similarly, this design makes the arrangement of the multiple sub-pixels 20 in the pixel unit for displaying the left-view image more compact, thereby helping to improve the display effect of the left-view image.

[0103] In some embodiments, as Figures 1 to 5 shown, the multiple first-type sub-pixels 21 include the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c with different emission colors. The multiple second-type sub-pixels 22 include the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c with different emission colors. The first group 31 includes the first sub-pixel 21a, the second sub-pixel 21b, the third sub-pixel 21c, the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c. Within a single first group 31, the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c are located on the same side of the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c in the first direction X. Among them, two adjacent first groups 31 closest to each other in the first direction X are arranged adjacent to each other, and two adjacent first groups 31 closest to each other in the second direction Y are arranged adjacent to each other.

[0104] Since the first group 31 includes at least three first-type sub-pixels 21 including the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c, a pixel unit for displaying a front-view image can be formed by relying on the multiple first-type sub-pixels 21 within a single first group 31. And since the first group 31 includes at least three second-type sub-pixels 22 including the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c, a pixel unit for displaying a left-view image can be formed by relying on the multiple second-type sub-pixels 22 within a single first group 31.

[0105] On this basis, the display panel 100 only needs to be provided with the first group 31, without the need to be provided with the second group 32 and the third group 33, and can meet the requirements of front-view display and left-view display. In view of this, in the embodiment of the present application, the two first groups 31 closest to each other in the first direction X are arranged adjacent to each other, that is, there are no other sub-pixels 20 between the two first groups 31 closest to each other in the first direction X. And the two first groups 31 closest to each other in the second direction Y are arranged adjacent to each other, that is, there are no other sub-pixels 20 between the two first groups 31 closest to each other in the second direction Y, so as to improve the arrangement regularity of the multiple sub-pixels 20 and reduce the design difficulty and manufacturing difficulty of the multiple sub-pixels 20.

[0106] In some alternative embodiments, the first sub-pixel 21a, the second sub-pixel 21b, and the third sub-pixel 21c are each one of the red sub-pixels 20, the green sub-pixels 20, and the blue sub-pixels 20, and the fourth sub-pixel 22a, the fifth sub-pixel 22b, and the sixth sub-pixel 22c are each one of the red sub-pixels 20, the green sub-pixels 20, and the blue sub-pixels 20.

[0107] In some embodiments, please refer to Figure 12 and Figure 13 , a plurality of first groups 31 are arranged in the second direction Y. Along the direction perpendicular to the plane of the substrate 11, the projection of the first type of sub-pixels 21 in the plurality of first groups 31 arranged in the second direction Y overlaps with the projection of the same first light-shielding opening 41 on the substrate 11; and / or, a plurality of first groups 31 are arranged in the second direction Y, and the light-shielding portions 50 in the plurality of first groups 31 arranged in the second direction Y are integrally connected.

[0108] A plurality of first groups 31 are arranged in the second direction Y. According to different specific pixel arrangement methods, the two first groups 31 closest to each other in the second direction Y can be arranged adjacent to each other, that is, there may be no other sub-pixels 20 between them. Or a second group 32 may also be provided between the two first groups 31 closest to each other in the second direction Y, that is, there are other sub-pixels 20 between them.

[0109] As can be seen from the accompanying drawings, a plurality of first-type sub-pixels 21 respectively arranged in different first groups 31 are arranged in the second direction Y. In view of this, in the embodiments of the present application, the size of a single first light-shielding opening 41 can be increased, so that the projection of the single first light-shielding opening 41 overlaps with the first-type sub-pixels 21 in the plurality of first groups 31, thereby increasing the size of the single first light-shielding opening 41, which helps to improve the display brightness of the display panel 100 and reduce the manufacturing difficulty of the first light-shielding layer 40. Alternatively, in the embodiments of the present application, the light-shielding portions 50 in the plurality of first groups 31 can be integrally connected, thereby increasing the size of a single light-shielding portion 50, which helps to enhance the light-shielding effect of the light-shielding portion 50 on the oblique light and improve the reliability of the independent display of the display panel 100 for different viewing angle images.

[0110] In some embodiments, referring to Figures 14 to 1 FIG. 7, the device layer 12 further includes third-type sub-pixels 23 for displaying third-view images. In a single first group 31, all the third-type sub-pixels 23 are located on the side of all the first-type sub-pixels 21 away from the second-type sub-pixels 22 along the first direction X. In a single first group 31, the light-shielding portion 50 includes a first light-shielding sub-portion 51 and a second light-shielding sub-portion 52. The first light-shielding sub-portion 51 is located on the side of the second-type sub-pixels 22 away from the first-type sub-pixels 21 along the first direction X, and the second light-shielding sub-portion 52 is located on the side of the third-type sub-pixels 23 away from the first-type sub-pixels 21 along the first direction X.

[0111] In addition to the first-type sub-pixels 21 and the second-type sub-pixels 22, the device layer 12 further includes third-type sub-pixels 23 for displaying third-view images, that is, the first-type sub-pixels 21, the second-type sub-pixels 22, and the third-type sub-pixels 23 are respectively used to display image screens of different viewing angles. For the convenience of understanding, in the embodiments of the present application, the following is an example in which the first-type sub-pixels 21 are used to display a front-view image, the second-type sub-pixels 22 are used to display a left-view image, and the third-type sub-pixels 23 are used to display a right-view image. Among them, Figure 17a shows the corresponding sub-pixel arrangement when the user observes the first-view image, Figure 17b shows the corresponding sub-pixel arrangement when the user observes the second-view image, Figure 17c shows the corresponding sub-pixel arrangement when the user observes the third-view image.

[0112] With reference to the accompanying drawings, in a single first group 31, all the third-type sub-pixels 23 and all the second-type sub-pixels 22 are arranged on both sides of all the first-type sub-pixels 21 along the first direction X. On this basis, the front-viewing light emitted by the first-type sub-pixel 21 can be emitted from the display panel 100 through the first light shielding opening 41, the left-viewing light emitted by the second-type sub-pixel 22 can be emitted from the display panel 100 through the first light shielding opening 41, and the right-viewing light emitted by the third-type sub-pixel 23 can be emitted from the display panel 100 through the first light shielding opening 41.

[0113] The light shielding portion 50 includes a first light shielding sub-portion 51 and a second light shielding sub-portion 52, and the first light shielding sub-portion 51 and the second light shielding sub-portion 52 are both used to shield light. Optionally, the first light shielding sub-portion 51 and the second light shielding sub-portion 52 may include the same material. The first light shielding sub-portion 51 is located along the first direction X on the side of the second type sub-pixel 22 away from the first type sub-pixel 21, and the right viewing angle light emitted by the second type sub-pixel 22 will be blocked and absorbed by the first light shielding sub-portion 51, thereby satisfying the reduction of the display effect of the second type sub-pixel 22 on other viewing angles. The second light shielding sub-portion 52 is located along the first direction X on the side of the third type sub-pixel 23 away from the first type sub-pixel 21, and the left viewing angle light emitted by the third type sub-pixel 23 will be blocked and absorbed by the first light shielding sub-portion 51, thereby satisfying the reduction of the display effect of the third type sub-pixel 23 on other viewing angles.

[0114] In summary, in the embodiment of the present application, by providing the first type of sub-pixel 21, the second type of sub-pixel 22 and the third type of sub-pixel 23 in the device layer 12, the display panel 100 can display at least three viewing angles, thereby improving the applicability of the display panel 100. Furthermore, in the embodiment of the present application, the light shielding portion 50 in the first group 31 is provided to include a first light shielding sub-portion 51 and a second light shielding sub-portion 52, and the interference effect of the sub-pixel 20 of a specific viewing angle on the images of other viewing angles is reduced by means of the first light shielding sub-portion 51 and the second light shielding sub-portion 52, thereby meeting the independent display needs of each viewing angle image and improving the viewing experience of the display panel 100.

[0115] In some embodiments, Figure 15 As shown, a plurality of sub-pixels 20 and a light shielding portion 50 together form a second group 32, and the second group 32 includes a first-type sub-pixel 21, a second-type sub-pixel 22, and a third-type sub-pixel 23. The first-type sub-pixels 21 in the first group 31 and the second group 32 have different colors. In a single second group 32, all the second-type sub-pixels 22 are located on one side of all the first-type sub-pixels 21 in the first direction X, and all the third-type sub-pixels 23 are located along the first direction X on one side of all the first-type sub-pixels 21 away from the second-type sub-pixels 22;

[0116] In a single second group 32, the light-shielding portion 50 includes a third light-shielding sub-portion 53 and a fourth light-shielding sub-portion 54. The third light-shielding sub-portion 53 is located on a side of the second-type sub-pixel 22 away from the first-type sub-pixel 21 along the first direction X, and the fourth light-shielding sub-portion 54 is located on a side of the third-type sub-pixel 23 away from the first-type sub-pixel 21 along the first direction X. Among them, a plurality of first groups 31 and a plurality of second groups 32 are arranged alternately in the first direction X. In adjacent first group 31 and second group 32, the first light-shielding sub-portion 51 and the fourth light-shielding sub-portion 54 are integrally connected; or, the second light-shielding sub-portion 52 and the third light-shielding sub-portion 53 are integrally connected. Among them, Figure 14 The first dividing line L1 and the second dividing line L2 are shown by thick dashed lines. The first dividing line L1 is the dividing line between the first light-shielding sub-portion 51 and the fourth light-shielding sub-portion 54, and the second dividing line L2 is the dividing line between the second light-shielding sub-portion 52 and the third light-shielding sub-portion 53.

[0117] In the embodiment of the present application, the display panel 100 includes both the first group 31 and the second group 32. Similar to the first group 31, the second group 32 also includes the first-type sub-pixel 21, the second-type sub-pixel 22, and the third-type sub-pixel 23. And in a single second group 32, all the third-type sub-pixels 23 and all the second-type sub-pixels 22 are disposed on both sides of all the first-type sub-pixels 21 along the first direction X.

[0118] On this basis, in order to meet the independent display requirements of each perspective picture, the embodiment of the present application further sets the light-shielding portion 50 in the second group 32 to include a third light-shielding sub-portion 53 and a fourth light-shielding sub-portion 54. The third light-shielding sub-portion 53 is located on a side of the second-type sub-pixel 22 away from the first-type sub-pixel 21 along the first direction X. The right-viewing angle light emitted by the second-type sub-pixel 22 will be blocked and absorbed by the first light-shielding sub-portion 51, so as to meet the requirement of reducing the display influence of the second-type sub-pixel 22 on other perspective pictures. The fourth light-shielding sub-portion 54 is located on a side of the third-type sub-pixel 23 away from the first-type sub-pixel 21 along the first direction X. The left-viewing angle light emitted by the third-type sub-pixel 23 will be blocked and absorbed by the first light-shielding sub-portion 51, so as to meet the requirement of reducing the display influence of the third-type sub-pixel 23 on other perspective pictures.

[0119] Further, a plurality of first groups 31 and a plurality of second groups 32 are alternately arranged in the first direction X. On this basis, for some of the first group 31 and the second group 32 adjacent in the first direction X, there are no other sub-pixels 20 and other structures between the second light-shielding sub-part 52 and the third light-shielding sub-part 53. In view of this, in the embodiment of the present application, the second light-shielding sub-part 52 and the third light-shielding sub-part 53 can be integrally connected, so as to simplify the preparation of the light-shielding part 50. Similarly, for some of the first group 31 and the second group 32 adjacent in the first direction X, there are no other sub-pixels 20 and other structures between the first light-shielding sub-part 51 and the fourth light-shielding sub-part 54. In view of this, in the embodiment of the present application, the first light-shielding sub-part 51 and the fourth light-shielding sub-part 54 can be integrally connected, so as to similarly simplify the preparation of the light-shielding part 50.

[0120] It should be noted that Figure 14 only one layout form of the display panel 100 is shown. According to different actual needs, the internal layout form of the display panel 100 can also be flexibly adjusted. Exemplarily, the display panel 100 can also adopt Figure 18 the arrangement form shown. In this case, the sub-pixels 20 of the same color can be arranged side by side in the second direction Y, while the different light-shielding parts 50 in adjacent rows are misaligned in the first direction X. Among them, Figures 19a to 19c is Figure 18 the arrangement mode of the sub-pixels corresponding to different perspective images. Specifically, Figure 19a shows the arrangement mode of the sub-pixels corresponding to the first perspective image observed by the user, Figure 19b shows the arrangement mode of the sub-pixels corresponding to the second perspective image observed by the user, Figure 19c shows the arrangement mode of the sub-pixels corresponding to the third perspective image observed by the user.

[0121] In some embodiments, within a single first group 31, the emission colors of the first type of sub-pixels 21 and the second type of sub-pixels 22 are different from each other, and the emission colors of the second type of sub-pixels 22 and the third type of sub-pixels 23 are the same. Within a single second group 32, the emission colors of the first type of sub-pixels 21 and the second type of sub-pixels 22 are different from each other, and the emission colors of the second type of sub-pixels 22 and the third type of sub-pixels 23 are the same.

[0122] Combined with Figure 15 For example, a single first group 31 may include two first type of sub-pixels 21, one second type of sub-pixels 22, and one third type of sub-pixels 23. The two first type of sub-pixels 21 are respectively a red sub-pixel 20 and a green sub-pixel 20, and they are arranged in the second direction Y, while the second type of sub-pixels 22 and the third type of sub-pixels 23 are both blue sub-pixels 20.

[0123] In the embodiments of the present application, by setting the emission colors of the first-type sub-pixels 21 and the second-type sub-pixels 22 within a single first group 31 to be different from each other, a certain distance can be provided between sub-pixels 20 with the same emission color, thereby improving the problem of excessive difficulty in preparing the mask plate caused by the too-close distance between the mask openings corresponding to sub-pixels 20 with the same emission color. On this basis, in the embodiments of the present application, the emission colors of the second-type sub-pixels 22 and the third-type sub-pixels 23 within a single first group 31 are set to be the same, so that the two can be prepared and formed together in the same process, thereby simplifying the preparation process of the device layer 12. The relationship among the first-type sub-pixels 21, the second-type sub-pixels 22, and the third-type sub-pixels 23 in the second group 32 is the same, and the present application does not make any limitations in this regard.

[0124] In some alternative embodiments, as Figure 15 shown, the emission color of the first-type sub-pixels 21 in the first group 31 is the same as that of the second-type sub-pixels 22 in the second group 32, and the emission color of the second-type sub-pixels 22 in the first group 31 is the same as that of the first-type sub-pixels 21 in the second group 32. Exemplarily, the number of the first-type sub-pixels 21 in the first group 31, the second-type sub-pixels 22 in the second group 32, and the third-type sub-pixels 23 in the second group 32 is two each, and all include a red sub-pixel 20 and a green sub-pixel 20 arranged in the second direction Y. The number of the second-type sub-pixels 22 in the first group 31, the third-type sub-pixels 23 in the first group 31, and the first-type sub-pixels 21 in the second group 32 is one each and all are blue sub-pixels 20.

[0125] Under this design, the arrangement of the multiple sub-pixels 20 in the display panel 100 is a relatively common arrangement in the related art. In other words, the embodiments of the present application can achieve a multi-view display effect by additionally adding a light-shielding portion 50 and adjusting the position of the first light-shielding opening 41 in the first light-shielding layer 40 without changing the pixel arrangement, which has strong practicability.

[0126] In some embodiments, the display panel 100 includes pixel circuits, and the multiple pixel circuits include a first-type circuit and a second-type circuit. The first-type circuit drives the first-type sub-pixels 21 to emit light, and the second-type circuit drives the second-type sub-pixels 22 to emit light.

[0127] The pixel circuit is a circuit structure for driving and controlling the sub-pixel 20 to achieve light-emitting display. The multiple pixel circuit structures include a first-type circuit for driving the first-type sub-pixel 21 and a second-type sub-pixel 22 for driving the second-type sub-pixel 22. In other words, in the embodiments of the present application, the first-type sub-pixel 21 and the second-type sub-pixel 22 are respectively driven and controlled by different pixel circuits. In this way, different viewing angle images are respectively driven and displayed by different pixel circuits, so that different viewing angle images can display different image information, meeting the need for independent display of multi-viewing angle images.

[0128] It should be noted that the pixel circuit usually includes device structures such as storage capacitors and thin-film transistors. Through different composition methods of multiple device structures, the pixel circuit can correspondingly have multiple types. For example, the pixel circuit can have a 7T1C circuit structure, that is, a single pixel circuit includes seven thin-film transistors and one storage capacitor. Or the pixel circuit can have an 8T2C circuit structure, that is, a single pixel circuit includes eight thin-film transistors and two storage capacitors. On this basis, according to different actual needs, the first-type circuit and the second-type circuit can be the same type of pixel circuit, or the two can also be different types of pixel circuits. The embodiments of the present application do not limit this.

[0129] In some alternative embodiments, the device layer 12 further includes a third-type sub-pixel 23 for displaying a third viewing angle image, and the multiple pixel circuits further include a third-type circuit for driving the third-type sub-pixel 23 to emit light.

[0130] In the embodiments of the present application, the first-type sub-pixel 21, the second-type sub-pixel 22, and the third-type sub-pixel 23 are respectively driven and controlled by different pixel circuits. In this way, the three viewing angle images corresponding to the first-type sub-pixel 21, the second-type sub-pixel 22, and the third-type sub-pixel 23 can respectively display different images, thereby further improving the applicability of the display panel 100 in the case of multi-viewing angle display.

[0131] In some embodiments, the display panel 100 further includes a pixel definition layer 60 on one side of the substrate 11. The pixel definition layer 60 includes a pixel limiting portion and a pixel opening 61 formed by surrounding the pixel limiting portion, and the sub-pixel 20 is disposed to cover the pixel opening 61.

[0132] In adjacent first-type sub-pixels 21 and second-type sub-pixels 22 of a single first group 31, the pixel opening 61 corresponding to the first-type sub-pixel 21 includes a first edge E1 facing away from the second-type sub-pixel 22, the pixel opening 61 corresponding to the second-type sub-pixel 22 includes a second edge E2 facing the first-type sub-pixel 21, the first light-shielding opening 41 has a third edge E3 in the first direction X, and in a direction perpendicular to the plane of the substrate 11, the projection of the third edge E3 is located between the projections of the first edge E1 and the second edge E2. Wherein, the distance between the third edge E3 and the first edge E1 in the first direction X is d1, the distance between the third edge E3 and the second edge E2 in the first direction X is d2, and d2≥d1.

[0133] The pixel definition layer 60 is a film layer structure in the display panel 100 for defining the positions of the sub-pixels 20. The pixel definition layer 60 includes pixel defining portions and pixel openings 61 formed by enclosing the pixel defining portions. The number of pixel openings 61 is multiple, and multiple sub-pixels 20 are respectively disposed to cover the multiple pixel openings 61. Wherein, the pixel opening 61 can define the light-emitting region of the corresponding sub-pixel 20. The opening formed by enclosing the pixel definition layer 60 includes an upper opening and a lower opening. Since the inner sidewall of the pixel definition layer 60 at the pixel opening 61 has an inclined structure and the cross-sectional shape in the thickness direction Z of the display panel 100 should be an inverted trapezoid, the upper opening is larger in size and the lower opening is smaller in size, and the pixel opening 61 mentioned in the embodiments of the present application is the lower opening of the pixel definition layer 60.

[0134] Combined Figure 16 To put it another way, the first edge E1 is the left edge of the pixel opening 61 corresponding to the first-type sub-pixel 21, the second edge E2 is the left edge of the pixel opening 61 corresponding to the second-type sub-pixel 22, and the third edge E3 is the right edge of the first light-shielding opening 41. On this basis, in order to meet the independent display requirements of the multi-view images of the display panel 100, the embodiments of the present application limit the relative distance relationship between the first edge E1, the second edge E2, and the third edge E3.

[0135] Specifically, taking the display of a positive-view image as an example, the angles θ1 and θ2 respectively represent the inclination angles corresponding to the maximum-view light rays on the left and right sides of the first-type sub-pixel 21. When the central axis corresponding to the first-type sub-pixel 21 coincides with the first light-shielding opening 41, the values of the angles θ1 and θ2 are the same. The angle θ3 represents the critical inclination angle of the light emitted by the second-type sub-pixel 22 that can pass through the first light-shielding opening 41. The light with an inclination angle less than θ3 emitted by the second-type sub-pixel 22 will be absorbed by the first light-shielding layer 40, and part of the light with an inclination angle greater than θ3 will pass through the first light-shielding opening 41.

[0136] On this basis, in order to meet the requirements of the front view image display and reduce the interference of the second type of sub-pixels 22 on the front view image, it is necessary to make the forward light emitted by the first type of sub-pixels 21 exit the display panel 100, and block and absorb the forward light emitted by the second type of sub-pixels 22. Therefore, θ1 and θ3 need to be set such that θ3≥θ1. In the embodiment of the present application, by setting d2 and d1 as d2≥d1, it is made that d2 / h1≥d1 / h1, where h1 is the distance between the pixel aperture 61 and the first light shielding layer 40 in the thickness direction Z of the display panel 100. And tanθ3 = d2 / h1, tanθ1 = d1 / (h1 + h2), where h2 is the thickness dimension of the first light shielding layer 40. Usually, h2 is much smaller than h1. Therefore, tanθ1≈d1 / h1. Thus, the design of d2≥d1 can make tanθ3≥tanθ1, that is, θ3≥θ1.

[0137] Taking the display of the left view image as an example, the angles θ4 and θ5 respectively represent the minimum tilt angle and the maximum tilt angle of the light emitted from the corresponding second type of sub-pixels 22. The angle θ6 represents the critical tilt angle of the light emitted by the first type of sub-pixels 21 that can pass through the first light shielding opening 41. The light emitted by the second type of sub-pixels 22 with a tilt angle less than θ6 can pass through the first light shielding opening 41, while the light with a tilt angle greater than θ6 will be blocked and absorbed by the first light shielding layer 40.

[0138] In order to meet the requirements of the left view image display and reduce the interference of the first type of sub-pixels 21 on the left view image, it is necessary to make the light emitted by the second type of sub-pixels 22 and tilted to the left exit the display panel 100, and block and absorb the light emitted by the first type of sub-pixels 21 and tilted to the left. Therefore, θ4 and θ6 need to be set such that θ4≥θ6. Combining the foregoing content, it can be seen that in the embodiment of the present application, by setting d2 and d1 as d2≥d1, it can make θ3≥θ1. And since θ4≈θ3, θ6≈θ1, the design of d2≥d1 can make θ4≥θ6.

[0139] In summary, in the embodiment of the present application, the relative distance relationship between the first edge E1, the second edge E2, and the third edge E3 is restricted, and the relationship between d1 and d2 is set as d2≥d1 to make θ3≥θ1, so as to reduce the interference of the second type of sub-pixels 22 on the front view image and improve the display effect of the front view image. And the design of d2≥d1 also makes θ4≥θ6, so as to reduce the interference of the first type of sub-pixels 21 on the left view image and improve the display effect of the left view image.

[0140] It should be noted that when the third type of sub-pixel 23 is included in the device layer 12, in order to improve the display effect of the right-view image, the relative distance relationship between the pixel opening 61 corresponding to the third type of sub-pixel 23 and the first light-shielding opening 41 can be similar to that in the foregoing embodiments, and the embodiments of the present application will not be elaborated herein.

[0141] In some embodiments, please refer to Figure 20 , the display panel 100 further includes a second light-shielding layer 70 disposed between the light-shielding portion 50 and the first light-shielding layer 40. The second light-shielding layer 70 includes a plurality of second light-shielding openings 71. The second light-shielding openings 71 are correspondingly disposed with the first light-shielding openings 41, and in a direction perpendicular to the plane where the substrate 11 is located, the first light-shielding openings 41 cover and extend beyond the second light-shielding openings 71.

[0142] The display panel 100 in the embodiments of the present application includes two light-shielding film layers, namely the first light-shielding layer 40 and the second light-shielding layer 70. The first light-shielding layer 40 is located on the side of the second light-shielding layer 70 away from the substrate 11. The first light-shielding layer 40 includes first light-shielding openings 41, and the second light-shielding layer 70 includes second light-shielding openings 71. The first light-shielding openings 41 are correspondingly disposed with the second light-shielding openings 71, and the size of the first light-shielding openings 41 is larger than that of the second light-shielding openings 71, so that the first light-shielding openings 41 can cover and extend beyond the second light-shielding openings 71.

[0143] As can be seen from the accompanying drawings, although the size of the second light-shielding openings 71 is smaller, since the second light-shielding layer 70 is disposed closer to the sub-pixels 20, the presence of the second light-shielding layer 70 will not affect the tilt angle range of the light emitted from the corresponding first type of sub-pixels 21. However, the presence of the second light-shielding layer 70 can help absorb some of the forward light emitted by the second type of sub-pixels 22. On this basis, even if d2 < d1, due to the presence of the second light-shielding layer 70, the forward light of the second type of sub-pixels 22 can still be blocked and absorbed, thereby further reducing the interference effect of the second type of sub-pixels 22 on the front-view image. Further, through this design, the distance between adjacent first type of sub-pixels 21 and second type of sub-pixels 22 can be selectively reduced accordingly, so as to increase the distribution density of the plurality of sub-pixels 20 in the display panel 100, thereby helping to improve the display accuracy of the image.

[0144] In a second aspect, please refer to Figure 21 , the embodiments of the present application provide a display device 200, and the display device 200 includes the display panel 100 in any of the foregoing embodiments.

[0145] It should be noted that the display device 200 provided in the embodiments of the present application has the beneficial effects of the display panel 100 in any of the foregoing embodiments. For specific reference, please refer to the description of the beneficial effects of the display panel 100 above, and the embodiments of the present application will not be elaborated herein.

[0146] Further, please refer to Figure 22 , the display device 200 provided by the embodiment of the present application can be applied to the in-vehicle display field. Among them, the display device 200 is located at the co-pilot position. The co-pilot user can observe the front view screen of the display device 200 through the first type of sub-pixels 21, while the driver user can observe the left view screen of the display device 200 through the second type of sub-pixels 22. On this basis, different image information can be displayed on the front view screen and the left view screen respectively to meet the different needs of the co-pilot user and the driver user.
