[0079] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0080] In related technologies, display panels can only display a single type of image, resulting in poor flexibility.

[0081] Figure 1 is a schematic diagram of a display panel according to an embodiment of this application. Referring to Figure 1, the display panel 100 includes: a substrate 101, a plurality of light-emitting units 102, a plurality of first-type light-shielding portions 103, and a plurality of second-type light-shielding portions 104. Referring to Figure 1, the substrate 101 includes a display area 101a and a peripheral area 101b surrounding the display area 101a. Referring to Figure 1, the plurality of light-emitting units 102 are located in the display area 101a.

[0082] Figure 2 is a partial top view of a display panel provided in an embodiment of this application. Referring to Figures 1 and 2, each light-emitting unit 102 includes a first sub-light-emitting unit 1021 and a second sub-light-emitting unit 1022 arranged along a first direction X. In this embodiment, the first sub-light-emitting unit 1021 is represented by a solid outer border, and the second sub-light-emitting unit 1022 is represented by a dashed outer border.

[0083] Each of the multiple first-type light-shielding portions 103 and the multiple second-type light-shielding portions 104 corresponds to a multiple light-emitting unit 102. For example, the multiple first-type light-shielding portions 103 correspond one-to-one with the multiple light-emitting units 102, that is, the number of first-type light-shielding portions 103 can be equal to the number of light-emitting units 102. The multiple second-type light-shielding portions 104 correspond one-to-one with the multiple light-emitting units 102, that is, the number of second-type light-shielding portions 104 can be equal to the number of light-emitting units 102.

[0084] The first type of light-shielding portion 103 is located on the first side of the corresponding light-emitting unit 102, and the orthographic projection of the first type of light-shielding portion 103 on the substrate 101 and the orthographic projection of the first sub-light-emitting unit 1021 on the substrate 101 are arranged along the second direction Y. The second type of light-shielding portion 104 is located on the second side of the corresponding light-emitting unit 102, and the orthographic projection of the second type of light-shielding portion 104 on the substrate 101 and the orthographic projection of the second sub-light-emitting unit 1022 on the substrate 101 are arranged along the second direction Y.

[0085] The second direction Y intersects with the first direction X. Optionally, the second direction Y can be perpendicular to the first direction X. For example, the first direction X can be the pixel column direction of the display panel 100, and the second direction Y can be the pixel row direction of the display panel 100.

[0086] In this context, the first side and the second side are different sides of the light-emitting unit 102, and the first side and the second side are arranged along the second direction Y. Optionally, in Figures 1 and 2, the first side of the light-emitting unit 102 can refer to the left side of the light-emitting unit 102, that is, the first type of light-shielding part 103 can be located to the left of the first sub-light-emitting unit 1021 in the light-emitting unit 102. The second side of the light-emitting unit 102 can refer to the right side of the light-emitting unit 102, that is, the second type of light-shielding part 104 can be located to the right of the second sub-light-emitting unit 1022 in the light-emitting unit 102.

[0087] Optionally, referring to Figure 3, the first side of the light-emitting unit 102 can also refer to the right side of the light-emitting unit 102, that is, the first type of light-shielding part 103 can be located to the right of the first sub-light-emitting unit 1021 in the light-emitting unit 102. The second side of the light-emitting unit 102 can also refer to the left side of the light-emitting unit 102, that is, the second type of light-shielding part 104 can be located to the left of the second sub-light-emitting unit 1022 in the light-emitting unit 102. The embodiments of this application do not limit the left and right positions of the first type of light-shielding part 103 and the second type of light-shielding part 104. Subsequent embodiments of this application will be described using the scheme shown in Figure 2 as an example.

[0088] In this embodiment, since the first type of light-shielding part 103 is located on one side of the first sub-light-emitting unit 1021 in the light-emitting unit 102, the light emitted by the first sub-light-emitting unit 1021 can be blocked and absorbed by the first type of light-shielding part 103, and the light emitted by the first sub-light-emitting unit 1021 (such as wide-angle light) will not be emitted from this side. At the same time, no light-shielding part is provided on one side of the second sub-light-emitting unit 1022 in the light-emitting unit 102, so the light emitted by the second sub-light-emitting unit 1022 can be emitted normally from this side.

[0089] Furthermore, since the second type of light-shielding part 104 is located on the other side of the second sub-light-emitting unit 1022 in the light-emitting unit 102, the light emitted by the second sub-light-emitting unit 1022 can be blocked and absorbed by the second type of light-shielding part 104, and the light emitted by the second sub-light-emitting unit 1022 (such as wide-angle light) will not be emitted from this other side. At the same time, no light-shielding part is provided on the other side of the first sub-light-emitting unit 1021 in the light-emitting unit 102, so the light emitted by the first sub-light-emitting unit 1021 can be emitted normally from this other side.

[0090] Referring to Figure 4, the first sub-light-emitting unit 1021 among the multiple light-emitting units 102 included in the display panel 100 can jointly display a single display image, allowing the user to observe this display image (hereinafter referred to as the first display image) from a second side (e.g., the right side) closer to the light-emitting unit 102. Simultaneously, the second sub-light-emitting unit 1022 among the multiple light-emitting units 102 included in the display panel 100 can jointly display another display image, allowing the user to observe this other display image (hereinafter referred to as the second display image) from a first side (e.g., the left side) closer to the light-emitting unit 102. In other words, the display panel 100 can display multiple display images, exhibiting high display flexibility.

[0091] In summary, the embodiments of this application provide a display panel, which includes a substrate, multiple light-emitting units, multiple first-type light-shielding portions, and multiple second-type light-shielding portions. The first-type light-shielding portions are located on one side of a first sub-light-emitting unit among the light-emitting units, and the second-type light-shielding portions are located on the other side of a second sub-light-emitting unit among the light-emitting units. This allows the first sub-light-emitting units of the multiple light-emitting units in the display panel to display one display image, and the second sub-light-emitting units of the multiple light-emitting units to display another display image; that is, the display panel can display multiple display images, providing high display flexibility.

[0092] In this embodiment, referring to FIG2, the orthographic projection of the first type of light-shielding portion 103 on the substrate 101 onto the reference plane C overlaps with the orthographic projection of the first sub-light-emitting unit 1021 on the substrate 101 onto the reference plane C, but does not overlap with the orthographic projection of the second sub-light-emitting unit 1022 on the substrate 101 onto the reference plane C. The reference plane C is perpendicular to the surface of the substrate 101 and parallel to the first direction X. FIG2 uses dashed lines to represent the orthographic projection of the reference plane C onto the substrate 101.

[0093] Optionally, the orthographic projection of the first type of light-shielding part 103 on the substrate 101 onto the reference plane C can cover the orthographic projection of the first sub-light-emitting unit 1021 on the substrate 101 onto the reference plane C, thereby ensuring that the first sub-light-emitting unit 1021 can be blocked by the first type of light-shielding part 103, thereby preventing the light emitted by the first sub-light-emitting unit 1021 from interfering with and affecting the second display screen.

[0094] The orthographic projection of the second type of light-shielding part 104 on the substrate 101 onto the reference plane C overlaps with the orthographic projection of the second sub-light-emitting unit 1022 on the substrate 101 onto the reference plane C, but does not overlap with the orthographic projection of the first sub-light-emitting unit 1021 on the substrate 101 onto the reference plane C.

[0095] Optionally, the orthographic projection of the second type of light-shielding part 104 on the substrate 101 onto the reference plane C can cover the orthographic projection of the second sub-light-emitting unit 1022 on the substrate 101 onto the reference plane C, thereby ensuring that the second sub-light-emitting unit 1022 can be blocked by the second type of light-shielding part 104, thereby preventing the light emitted by the second sub-light-emitting unit 1022 from interfering with and affecting the first display screen.

[0096] In this embodiment, FIG5 is a cross-sectional view of FIG2 along the AA' direction. FIG6 is a cross-sectional view of FIG2 along the BB' direction. Referring to FIG5 and FIG6, the display panel 100 further includes an encapsulation film layer 105 located on the side of the plurality of light-emitting units 102 away from the substrate 101. At least a portion of each of the plurality of first-type light-shielding portions 103 and the plurality of second-type light-shielding portions 104 is located on the side of the encapsulation film layer 105 away from the substrate 101.

[0097] Referring to Figures 5 and 6, the display panel 100 includes a first light-shielding layer 106 and a first protective layer 107, which are stacked on the side of the encapsulation film layer 105 away from the substrate 101 and in a direction away from the substrate 101. The first light-shielding layer 106 includes a first light-shielding portion 1061 of a first type of light-shielding portion 103 and a first light-shielding portion 1061 of a second type of light-shielding portion 104. In this case, both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 include the first light-shielding portion 1061 located in the first light-shielding layer 106.

[0098] Referring to Figures 7 and 8, the display panel 100 further includes a second light-shielding layer 108 and a second protective layer 109, which are located on the side of the first protective layer 107 away from the substrate 101 and are stacked in a direction away from the substrate 101. The second light-shielding layer 108 includes a second light-shielding portion 1081 of a first type of light-shielding portion 103 and a second light-shielding portion 104. In this case, both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 include a first light-shielding portion 1061 located in the first light-shielding layer 106 and a second light-shielding portion 1081 located in the second light-shielding layer 108.

[0099] Compared to the display panels shown in Figures 5 and 6, the first type of light-shielding part 103 and the second type of light-shielding part 104 of the display panels shown in Figures 7 and 8 use more layers of light-shielding parts to block the light from the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display screens.

[0100] In this embodiment, taking a display panel 100 including a first light-shielding layer 106 and a second light-shielding layer 108 as an example, the stacking relationship and position of the light-emitting unit 102 under four different viewing angles are described. Referring to Figures 9 to 13, the second sub-light-emitting unit 1022 can be observed under the first viewing angle; the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 can be observed under the second viewing angle; the first sub-light-emitting unit 1021 can be observed under the third viewing angle; and the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 can be observed under the fourth viewing angle.

[0101] Referring to Figures 5 to 8 and Figures 10 to 13, the display panel 100 includes a light-emitting device layer M located on one side of a substrate 101, the light-emitting device layer M including a plurality of light-emitting units 102. The light-emitting device layer M includes an anode layer m1, a pixel defining layer m2, a light-emitting layer m3, and a cathode layer m4.

[0102] The anode layer m1 includes a first anode portion m11 of a first sub-light-emitting unit 1021 of each of the plurality of light-emitting units 102, and a second anode portion m12 of a second sub-light-emitting unit 1022 of each of the plurality of light-emitting units 102. The orthographic projection of the first anode portion m11 on the substrate 101 and the orthographic projection of the second anode portion m12 on the substrate 101 are arranged along a first direction X, and the first anode portion m11 and the second anode portion m12 are spaced apart.

[0103] The pixel defining layer m2 includes multiple first cutout areas m2a and multiple second cutout areas m2b. The multiple first cutout areas m2a correspond to multiple light-emitting units 102. The first cutout areas m2a expose at least a portion of the first anode portion m11 of the first sub-light-emitting unit 1021 of the corresponding light-emitting unit 102. The multiple second cutout areas m2b correspond to the multiple light-emitting units 102. The second cutout areas m2b expose at least a portion of the second anode portion m12 of the second sub-light-emitting unit 1022 of the corresponding light-emitting unit 102.

[0104] The light-emitting layer m3 includes a first light-emitting portion m31 of a first sub-light-emitting unit 1021 of each of the plurality of light-emitting units 102, and a second light-emitting portion m32 of a second sub-light-emitting unit 1022 of each of the plurality of light-emitting units 102. The first light-emitting portion m31 is located within a first hollow area m2a and is connected to a first anode portion m11. The second light-emitting portion m32 is located within a second hollow area m2b and is connected to a second anode portion m12. Optionally, the first light-emitting portion m31 and the second light-emitting portion m32 can be spaced apart or connected as a whole; this embodiment does not limit this.

[0105] The cathode layer m4 is located on the side of the first light-emitting part m31 and the second light-emitting part m32 away from the substrate 101, and the cathode layer m4 is connected to the first light-emitting part m31 and the second light-emitting part m32. That is, the cathode layer m4 can serve as a common cathode for multiple light-emitting units 102.

[0106] In this embodiment of the application, referring to Figures 14 and 15, the display panel 100 includes a third light-shielding layer 110 located on the side of the pixel defining layer m2 away from the substrate 101. The third light-shielding layer 110 includes a third light-shielding portion 1101 of a first type of light-shielding portion 103 and a third light-shielding portion 1101 of a second type of light-shielding portion 104. The third light-shielding layer 110 may be located between the pixel defining layer m2 and the cathode layer m4.

[0107] In the display panel 100 shown in FIG. 14, both the first type of light-shielding part 103 and the second type of light-shielding part 104 may include: a first light-shielding part 1061 located in the first light-shielding layer 106, and a third light-shielding part 1101 located in the third light-shielding layer 110. In this case, the first type of light-shielding part 103 and the second type of light-shielding part 104 use two layers of light-shielding parts to block the light from the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display images.

[0108] In the display panel 100 shown in Figure 15, both the first type of light-shielding part 103 and the second type of light-shielding part 104 may include: a first light-shielding part 1061 located in the first light-shielding layer 106, a second light-shielding part 1081 located in the second light-shielding layer 108, and a third light-shielding part 1101 located in the third light-shielding layer 110. In this case, since both the first type of light-shielding part 103 and the second type of light-shielding part 104 include three layers of light-shielding parts, the light-shielding effect is improved compared to a solution with one or two layers of light-shielding parts, thus preventing different display images on the display panel from interfering with each other.

[0109] In this embodiment, in Figures 14 and 15 above, the first type of light-shielding portion 103 includes the same number of light-shielding layers as the second type of light-shielding portion 104. However, the number of light-shielding layers in the first type of light-shielding portion 103 and the second type of light-shielding portion 104 can actually differ; for example, the first type of light-shielding portion may include two layers, and the second type of light-shielding portion may include three layers. This embodiment does not specifically limit this.

[0110] Optionally, when both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 include a single layer of light-shielding portion, the light-shielding portion included in the first type of light-shielding portion 103 may be located on the same layer as the light-shielding portion included in the second type of light-shielding portion 104, or they may be located on different layers. When both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 include multiple layers of light-shielding portion, the multiple layers of light-shielding portion included in the first type of light-shielding portion 103 may be located on the same layer in a one-to-one correspondence with the multiple layers of light-shielding portion included in the second type of light-shielding portion 104, or at least a portion of the multiple layers of light-shielding portion included in the first type of light-shielding portion 103 may be located on different layers from the light-shielding portion included in the second type of light-shielding portion 104.

[0111] For example, the first light-shielding portion 1061 of the first type of light-shielding portion 103 shown in FIG. 5 and the first light-shielding portion 1061 of the second type of light-shielding portion 104 shown in FIG. 6 can both be located in the first light-shielding layer 106. Alternatively, the first light-shielding portion of the first type of light-shielding portion 103 and the first light-shielding portion of the second type of light-shielding portion 104 can also be located in different light-shielding layers.

[0112] For example, the first light-shielding portion 1061 of the first type of light-shielding portion 103 shown in FIG. 7 and the first light-shielding portion 1061 of the second type of light-shielding portion 104 shown in FIG. 8 can both be located in the first light-shielding layer 106; the second light-shielding portion 1081 of the first type of light-shielding portion 103 shown in FIG. 7 and the second light-shielding portion 1081 of the second type of light-shielding portion 104 shown in FIG. 8 can both be located in the second light-shielding layer 108. Alternatively, at least one of the first and second light-shielding portions of the first type of light-shielding portion 103 is located in a different layer from the first and second light-shielding portions of the second type of light-shielding portion 104.

[0113] In this embodiment of the application, referring to Figures 16 and 17, the display panel 100 includes a fourth light-shielding layer 111 located on the side of the cathode layer m4 away from the substrate 101. The fourth light-shielding layer 111 includes a fourth light-shielding portion 1111 of a first type of light-shielding portion 103 and a fourth light-shielding portion 1111 of a second type of light-shielding portion 104. The fourth light-shielding layer 111 may be located between the cathode layer m4 and the encapsulation film layer 105.

[0114] In the display panel 100 shown in FIG. 16, both the first type of light-shielding part 103 and the second type of light-shielding part 104 may include: a first light-shielding part 1061 located in the first light-shielding layer 106, and a fourth light-shielding part 1111 located in the fourth light-shielding layer 111. In this case, the first type of light-shielding part 103 and the second type of light-shielding part 104 use two layers of light-shielding parts to block the light from the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display images. Alternatively, the number of light-shielding layers included in the first type of light-shielding part 103 may be different from the number of light-shielding layers in the second type of light-shielding part.

[0115] In the display panel 100 shown in FIG. 17, both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 may include: a first light-shielding portion 1061 located in the first light-shielding layer 106, a second light-shielding portion 1081 located in the second light-shielding layer 108, and a fourth light-shielding portion 1111 located in the fourth light-shielding layer 111. In this case, since both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 include three layers of light-shielding portions, the light-shielding effect is improved compared to a solution with one or two layers of light-shielding portions, thus preventing different display images on the display panel from interfering with each other. Alternatively, the number of light-shielding layers included in the first type of light-shielding portion 103 may be different from the number of layers in the second type of light-shielding portion.

[0116] In this embodiment, referring to Figures 18 and 19, the material of the pixel defining layer m2 in the display panel 100 can be a light-shielding material. In this case, the pixel defining layer m2 can be reused as the fifth light-shielding layer 112.

[0117] In the display panel 100 shown in FIG18, both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 may include: a first light-shielding portion 1061 located in the first light-shielding layer 106, and a portion located in the pixel defining layer m2 (the fifth light-shielding layer 112). In this case, the first type of light-shielding portion 103 and the second type of light-shielding portion 104 use two layers of light-shielding portions to block the light from the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display images.

[0118] In the display panel 100 shown in FIG19, both the first type of light-shielding part 103 and the second type of light-shielding part 104 may include: a first light-shielding part 1061 located in the first light-shielding layer 106, a second light-shielding part 1081 located in the second light-shielding layer 108, and a fifth light-shielding part 1112 located in the pixel defining layer m2 (the fifth light-shielding layer 112). In this case, since both the first type of light-shielding part 103 and the second type of light-shielding part 104 include three layers of light-shielding parts, the light-shielding effect is improved compared to a solution with one or two layers of light-shielding parts, thus preventing different display images of the display panel 100 from interfering with each other.

[0119] In this embodiment, the display panel 100 further includes multiple light-shielding layers, thereby improving the light-shielding effect on the light emitted by the sub-light-emitting unit 102. This embodiment does not specifically limit the number of light-shielding layers included in the display panel 100.

[0120] Optionally, the arrangement of the first type of light-shielding part 103 and the arrangement of the second type of light-shielding part 104 listed in the embodiments of this application can be combined as needed. For example, the first type of light-shielding part 103 can be the first type of light-shielding part shown in FIG15. The second type of light-shielding part 104 can be the second type of light-shielding part shown in FIG16.

[0121] Optionally, to ensure the light-shielding effect, the distance between the light-shielding layer furthest from the substrate 101 and the light-shielding layer closest to the substrate 101 in the display panel can range from 5 μm to 50 μm.

[0122] For example, in the display panel 100 shown in Figure 16, the display panel 100 includes a first light-shielding layer 106 and a fourth light-shielding layer 111. The first light-shielding layer 106 is the light-shielding layer in the display panel 100 that is furthest from the substrate 101, and the fourth light-shielding layer 111 is the light-shielding layer in the display panel 100 that is closest to the substrate 101. The distance h between the first light-shielding layer 106 and the fourth light-shielding layer 111 can be 10 μm.

[0123] For example, in the display panel 100 shown in Figure 17, the display panel 100 includes a first light-shielding layer 106, a second light-shielding layer 108, and a fourth light-shielding layer 111. The second light-shielding layer 108 is the light-shielding layer in the display panel 100 furthest from the substrate 101, and the fourth light-shielding layer 111 is the light-shielding layer in the display panel 100 closest to the substrate 101. The distance h between the second light-shielding layer 108 and the fourth light-shielding layer 111 can be 40 μm.

[0124] For example, in the display panel 100 shown in Figure 19, the display panel 100 includes a first light-shielding layer 106, a second light-shielding layer 108, and a fifth light-shielding layer 112 (a pixel delimiting layer m2 made of a light-shielding material). The second light-shielding layer 108 is the light-shielding layer in the display panel 100 furthest from the substrate 101, and the fifth light-shielding layer 112 is the light-shielding layer in the display panel 100 closest to the substrate 101. The distance between the second light-shielding layer 108 and the fifth light-shielding layer 112 can be 45 μm.

[0125] In this embodiment of the application, referring to FIG20, the display panel 100 further includes a plurality of third-type light-shielding portions 113. The plurality of third-type light-shielding portions 113 are correspondingly disposed with at least a portion of the plurality of light-emitting units 102, the third-type light-shielding portions 113 being located on the third side of the corresponding light-emitting unit 102, and the third side and the light-emitting unit 102 being arranged along a first direction X. Optionally, each light-emitting unit 102 may correspond to one third-type light-shielding portion 113, and the third-type light-shielding portion 113 may be located on the third side of the light-emitting unit 102. Alternatively, each light-emitting unit 102 may correspond to two third-type light-shielding portions 113, one of which is located on the third side of the light-emitting unit 102, and the other third-type light-shielding portion 113 is located between the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022.

[0126] When the display panel 100 is used in a vehicle display, the light emitted from the light-emitting unit 102 from the upper side (or upper viewing angle) can be blocked by setting a third type of light-shielding part 113, so as to prevent the light from being projected onto the vehicle windshield, reduce the impact on the driver, and improve driving safety.

[0127] Optionally, the third side of the light-emitting unit 102 can refer to the upper side of the light-emitting unit 102. For example, a plurality of third-type light-shielding parts 113 can be correspondingly arranged with a plurality of light-emitting units 102 located in the upper half of the display area 101a in the display panel 100. That is, the plurality of third-type light-shielding parts 113 are located on the upper side of the plurality of light-emitting units 102 in the upper half. Alternatively, the plurality of third-type light-shielding parts 113 can be correspondingly arranged with a plurality of light-emitting units 102 in the display panel 100. That is, each third-type light-shielding part 113 can be located on the upper side of a corresponding light-emitting unit 102.

[0128] In this embodiment, referring to FIG21, three light-emitting units 102 (red light-emitting unit R, green light-emitting unit G, and blue light-emitting unit B) are shown, and correspondingly, three data lines can be designed to correspond to the three light-emitting units 102. Referring to FIG22, three light-emitting units 102 are shown, and each light-emitting unit 102 includes a first sub-light-emitting unit 1021 and a second sub-light-emitting unit 1022. That is, the three light-emitting units 103 are divided into six sub-light-emitting units, and thus six data lines need to be designed to correspond to the six sub-light-emitting units. In other words, since the light-emitting unit 102 is divided into the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022, the number of data lines used to provide data signals is doubled, which in turn doubles the number of chip-on-film (COF) films connected to the data lines, and the spacing of the different bonding pins of the COF is greatly compressed, leading to short circuit or open circuit problems.

[0129] Referring to Figure 23, the display panel 100 further includes: a multiplexer 114, a signal input line 115, a first data signal line 116, and a second data signal line 117. The multiplexer 114 includes: a first signal selection control line 1141, a second signal selection control line 1142, a first transistor T1, and a second transistor T2. Both the first transistor T1 and the second transistor T2 include a gate, a first electrode, and a second electrode.

[0130] The gate of the first transistor T1 is connected to the first signal selection control line 1141, the first terminal of the first transistor T1 is connected to the signal input line 115, and the second terminal of the first transistor T1 is connected to the first data signal line 116. The gate of the second transistor T2 is connected to the second signal selection control line 1142, the first terminal of the second transistor T2 is connected to the signal input line 115, and the second terminal of the second transistor T2 is connected to the second data signal line 117.

[0131] The first signal selection control line 1141 provides a first control signal to the gate of the first transistor T1, which turns the first transistor T1 on or off under the action of the first control signal. The first data signal line 116 is also connected to the first target sub-light-emitting unit, which receives data signals transmitted from the signal input line 115 when the first transistor T1 is in the on state. The second signal selection control line 1142 provides a second control signal to the gate of the second transistor T2, which turns the second transistor T2 on or off under the action of the second control signal. The second data signal line 117 is also connected to the second target sub-light-emitting unit, which receives data signals transmitted from the signal input line 115 when the second transistor T2 is in the on state. The first target sub-light-emitting unit and the second target sub-light-emitting unit are different sub-light-emitting units.

[0132] Optionally, signal input line 115 can be connected to both the first target sub-light-emitting unit and the second target sub-light-emitting unit. Furthermore, the first target sub-light-emitting unit and the second target sub-light-emitting unit connected to signal input line 115 can be the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 within the same light-emitting unit 102. Alternatively, the first target sub-light-emitting unit and the second target sub-light-emitting unit can be sub-light-emitting units 102 from different light-emitting units 102.

[0133] In this embodiment, the first terminal of the first transistor T1 connected to the first target sub-light-emitting unit and the first terminal of the second transistor T2 connected to the second target sub-light-emitting unit can be connected to the same signal input line 115. Therefore, when the first transistor T1 is on, the signal input line 115 can transmit the data signal to the first target sub-light-emitting unit through the first transistor T1; when the second transistor T2 is on, the signal input line 115 can transmit the data signal to the second target sub-light-emitting unit through the second transistor T2. Optionally, the switching state of the first transistor T1 can be controlled by the first signal selection control line 1141, and the switching state of the second transistor T2 can be controlled by the second signal selection control line 1142, thereby enabling the signal input line 115 to transmit the data signal to the corresponding sub-light-emitting unit 102 through the transistor in the on state. That is, the multiplexer 114 can be a 1:2 driving scheme. In this case, the number of signal input lines 115 can be reduced, which in turn reduces the number of COFs connected to the signal input lines 115. The spacing between different bonding pins of the COFs can also be appropriately increased to reduce the probability of short circuits or open circuits.

[0134] Optionally, referring to Figure 23, the plurality of light-emitting units 102 include a plurality of light-emitting units 102a of a first color, a plurality of light-emitting units 102b of a second color, and a plurality of light-emitting units 102c of a third color. The first color, the second color, and the third color are all different from each other.

[0135] Optionally, the first color can be red (R), the second color can be green (G), and the third color can be blue (B). The first color light-emitting unit 102a can be a red light-emitting unit 102-R. The second color light-emitting unit 102b can be a green light-emitting unit 102-G. The third color light-emitting unit 102c can be a blue light-emitting unit 102-B.

[0136] Alternatively, the first color can be red, the second color blue, and the third color green. The first color light-emitting unit 102a can be a red light-emitting unit 102-R. The second color light-emitting unit 102b can be a blue light-emitting unit 102-B. The third color light-emitting unit 102c can be a green light-emitting unit 102-G.

[0137] In this group, a light-emitting unit 102a of a first color, a light-emitting unit 102b of a second color, and a light-emitting unit 102c of a third color constitute a light-emitting unit group Z. That is, the light-emitting unit group Z may include a red light-emitting unit 102-R, a green light-emitting unit 102-G, and a blue light-emitting unit 102-B.

[0138] Referring to Figure 23, taking a light-emitting unit group Z as an example, the display panel 100 includes three first data signal lines 116, three second data signal lines 117, and three signal input lines 115 corresponding to the light-emitting unit group Z. The multiplexer 114 includes three first transistors T1 and three second transistors T2 corresponding to the light-emitting unit group Z. The three signal input lines 115 are correspondingly configured with one first transistor T1 and one second transistor T2. That is, each of the three signal input lines 115 is configured with one first transistor T1 and one second transistor T2.

[0139] Each of the three signal input lines 115 is connected to a corresponding first transistor T1 and a corresponding second transistor T2. The second terminals of the three first transistors T1 are connected to three first data signal lines 116, which are respectively connected to the first sub-light-emitting unit 1021 of the first-color light-emitting unit 102a, the first sub-light-emitting unit 1021 of the second-color light-emitting unit 102b, and the first sub-light-emitting unit 1021 of the third-color light-emitting unit 102c in the light-emitting unit group Z. The second terminals of the three second transistors T2 are connected to three second data signal lines 117, which are respectively connected to the second sub-light-emitting unit 1022 of the first-color light-emitting unit 102a, the second sub-light-emitting unit 1022 of the second-color light-emitting unit 102b, and the second sub-light-emitting unit 1022 of the third-color light-emitting unit 102c in the light-emitting unit group Z.

[0140] Referring to Figure 23, the first signal input line 115 of the three signal input lines 115 is connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the first color light-emitting unit 102a. The second signal input line 115 of the three signal input lines 115 is connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b. The third signal input line 115 of the three signal input lines 115 is connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the third color light-emitting unit 102c.

[0141] For example, in the scheme shown in Figure 23, three first transistors T1 are connected to the first sub-light-emitting unit 1021 of the first color light-emitting unit 102a, the first sub-light-emitting unit 1021 of the second color light-emitting unit 102b, and the first sub-light-emitting unit 1021 of the third color light-emitting unit 102c, respectively. Correspondingly, three first data signal lines 116 are connected to the three first transistors T1. Three second transistors T2 are connected to the second sub-light-emitting unit 1022 of the first color light-emitting unit 102a, the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b, and the second sub-light-emitting unit 1022 of the third color light-emitting unit 102c, respectively. Correspondingly, three second data signal lines 117 are connected to the three second transistors T2.

[0142] In this embodiment, for a driving scheme where the multiplexer 114 can be 1:2, the three signal input lines 115 can be connected to any two different sub-light-emitting units 102 in the light-emitting unit group Z. The multiplexer 114 being 1:2 can be used to indicate that the number of signal input lines 115 is 1:2 with the number of data signal lines.

[0151] In this embodiment, referring to FIG28, the display panel 100 further includes a third data signal line 118. The multiplexer 114 further includes a third signal selection control line 1143 and a third transistor T3. The third transistor T3 includes a gate, a first electrode, and a second electrode.

[0152] The third signal selection control line 1143 provides a third control signal to the gate of the third transistor T3, which turns the third transistor T3 on or off under the action of the third control signal. The third data signal line 118 is also connected to the third target sub-light-emitting unit, which receives the data signal transmitted from the signal input line 115 when the third transistor T3 is in the on state. The third target sub-light-emitting unit, the first target sub-light-emitting unit, and the second target sub-light-emitting unit are different sub-light-emitting units from each other.

[0153] Optionally, the signal input line 115 can be connected to the first target sub-light-emitting unit, the second target sub-light-emitting unit, and the third target sub-light-emitting unit. Furthermore, the first target sub-light-emitting unit, the second target sub-light-emitting unit, and the third target sub-light-emitting unit connected to the signal input line 115 can be different sub-light-emitting units 102.

[0154] Referring to Figure 28, taking a light-emitting unit group Z as an example, the display panel 100 includes two first data signal lines 116, two second data signal lines 117, two third data signal lines 118, and two signal input lines 115 corresponding to the light-emitting unit group Z. The multiplexer 114 includes two first transistors T1, two second transistors T2, and two third transistors T3 corresponding to the light-emitting unit group Z. The two signal input lines 115 are correspondingly configured with the two first transistors T1, two second transistors T2, and two third transistors T3. That is, each of the two signal input lines 115 is configured with one first transistor T1, one second transistor T2, and one third transistor T3.

[0155] Each of the two signal input lines 115 is connected to a corresponding first transistor T1, a corresponding second transistor T2, and a corresponding third transistor T3. The second terminals of the two first transistors T1 are connected to two first data signal lines 116, which are respectively connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the first color light-emitting unit 102a in the light-emitting unit group Z. The second terminals of the two second transistors T2 are connected to two second data signal lines 117, which are respectively connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b in the light-emitting unit group Z. The second terminals of the two third transistors T3 are connected to two third data signal lines 118, which are respectively connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the third color light-emitting unit 102c in the light-emitting unit group Z.

[0156] Referring to Figure 28, the first signal input line 115 of the two signal input lines 115 is connected to the first sub-light-emitting unit 1021 of the first color light-emitting unit 102a, the first sub-light-emitting unit 1021 of the second color light-emitting unit 102b, and the first sub-light-emitting unit 1021 of the third color light-emitting unit 102c. The second signal input line 115 of the two signal input lines 115 is connected to the second sub-light-emitting unit 1022 of the first color light-emitting unit 102a, the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b, and the second sub-light-emitting unit 1022 of the third color light-emitting unit 102c.

[0157] For example, in the scheme shown in Figure 28, two first transistors T1 are connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the first color light-emitting unit 102a, respectively. Correspondingly, two first data signal lines 116 are connected to the two first transistors T1. Two second transistors T2 are connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b, respectively. Correspondingly, two second data signal lines 117 are connected to the two second transistors T2. Two third transistors T3 are connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the third color light-emitting unit 102c, respectively. Correspondingly, two third data signal lines 118 are connected to the two third transistors T3.

[0158] In this embodiment, for a driving scheme where the multiplexer 114 can be 1:3, the two signal input lines 115 can be connected to any three different sub-light-emitting units in the light-emitting unit group Z. The multiplexer 114 being 1:3 can be used to indicate that the number of signal input lines 115 is in a 1:3 ratio to the number of data signal lines.

[0159] The above embodiments of this application use the division of a light-emitting unit into two sub-light-emitting units as an example to achieve a dual-view display function for the display panel. In reality, the light-emitting unit can be divided into a larger number of sub-light-emitting units (for example, it can be divided into 2n sub-light-emitting units, where n is an integer and 2n represents an even number), and the dual-view display function of the display panel can still be achieved. For example, the light-emitting unit can be divided into two sub-light-emitting units, four sub-light-emitting units, and six sub-light-emitting units, etc.

[0160] Optionally, in addition to dual-view display, the display panel can also implement active privacy protection and shared display functions. The light-emitting unit can be divided into an even or even number of sub-light-emitting units. For example, the light-emitting unit can be divided into one shared sub-light-emitting unit and multiple privacy-protecting sub-light-emitting units. For instance, the light-emitting unit can be divided into sub-light-emitting unit a1, sub-light-emitting unit a2, and sub-light-emitting unit a3. Assuming sub-light-emitting unit a1 is the shared sub-light-emitting unit, sub-light-emitting units a2 and a3 can be privacy-protecting sub-light-emitting units. Sub-light-emitting unit a1 can emit light when implementing the shared display function, while sub-light-emitting units a2 and a3 can emit light when implementing dual-view display, active privacy protection, and shared display functions.

[0161] Sub-light-emitting unit a2 can provide a display function that shows to a first side (which can be the left side) and provides privacy protection to a second side (which can be the right side). Sub-light-emitting unit a3 can provide a display function that shows to a second side (which can be the right side) and provides privacy protection to a first side (which can be the left side). Sub-light-emitting units a2 and a3 can provide a shared display function when emitting light based on the same image.

[0162] Taking a light-emitting unit group Z as an example, which includes a light-emitting unit 102a of a first color, a light-emitting unit 102b of a second color, and a light-emitting unit 102c of a third color, and the light-emitting units of the three colors are all divided into a first sub-light-emitting unit 1021 and a second sub-light-emitting unit 1022.

[0163] Assume that the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the three-color light-emitting units are both privacy-protected sub-light-emitting units. When the display panel is in privacy-protected display mode or dual-view display mode, the first sub-light-emitting unit 1021 of the three-color light-emitting units can display the first display image to the second side but not to the first side, and the second sub-light-emitting unit 1022 of the three-color light-emitting units can display the second display image to the first side but not to the second side.

[0164] Assume that the first sub-light-emitting units 1021 of the three-color light-emitting units are all privacy-protected sub-light-emitting units, and the second sub-light-emitting units 1022 of the three-color light-emitting units are all shared sub-light-emitting units. When the display panel is in shared display mode, the second sub-light-emitting units 1022 of the three-color light-emitting units can be made to emit light, or both the first sub-light-emitting units 1021 and 1022 of the three-color light-emitting units can be made to emit light. In shared display mode, the first sub-light-emitting units 1021 and 1022 of the three-color light-emitting units can display the same image. When the display panel is in privacy-protected display mode, the first sub-light-emitting units 1021 of the three-color light-emitting units can be made to emit light as privacy-protected sub-light-emitting units, and the second sub-light-emitting units 1022 of the three-color light-emitting units can be made not to emit light.

[0165] When multiple sub-light-emitting units obtained by dividing the light-emitting unit include a shared sub-light-emitting unit, the side of the shared sub-light-emitting unit does not need to be provided with a light-shielding part, so that the light emitted by the shared sub-light-emitting unit will not be blocked by the light-shielding part.

[0166] In this embodiment, the arrangement of the light-emitting units in the accompanying drawings is only one example. In reality, the light-emitting units can be arranged in other ways. This embodiment does not specifically limit the arrangement of multiple light-emitting units in the display panel. For example, the multiple light-emitting units included in the display panel can be arranged in RGB, Pentile, diamond, Delta, etc.

[0167] Optionally, the light-shielding portion between two adjacent light-emitting units in the second direction Y can be shared. Taking the arrangement shown in Figure 2 as an example, a second type of light-shielding portion 104 corresponding to the second sub-light-emitting unit 1022 in the second color light-emitting unit 102b and a first type of light-shielding portion 103 corresponding to the third color light-emitting unit 102c are provided between the second sub-light-emitting unit 102b and the first sub-light-emitting unit 1021 in the third color light-emitting unit 102c.

[0168] Referring to Figure 29, the second type of light-blocking portion 104 corresponding to the second color light-emitting unit 102b and the first type of light-blocking portion 103 corresponding to the third color light-emitting unit 102c can be connected together to form a whole light-blocking portion. That is, the second type of light-blocking portion 104 corresponding to the second color light-emitting unit 102b and the first type of light-blocking portion 103 corresponding to the third color light-emitting unit 102c can be without gaps.

[0169] Alternatively, referring to Figure 30, since the first type of light-shielding part 103 corresponding to the third color light-emitting unit 102c is located on the second side of the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b, it can be reused as the second type of light-shielding part 104 corresponding to the second color light-emitting unit 102b. That is, the second type of light-shielding part 104 corresponding to the second color light-emitting unit 102b can be omitted, and the first type of light-shielding part 103 corresponding to the third color light-emitting unit 102c can be directly used to block the second sub-light-emitting unit 1022 of the second color light-emitting unit 102b from emitting light to the second side. This allows the light-shielding part between the two light-emitting units to occupy less space, which is beneficial for the realization of high-resolution products.

[0170] In summary, the embodiments of this application provide a display panel, which includes a substrate, multiple light-emitting units, multiple first-type light-shielding portions, and multiple second-type light-shielding portions. The first-type light-shielding portions are located on one side of a first sub-light-emitting unit among the light-emitting units, and the second-type light-shielding portions are located on the other side of a second sub-light-emitting unit among the light-emitting units. This allows the first sub-light-emitting units of the multiple light-emitting units in the display panel to display one display image, and the second sub-light-emitting units of the multiple light-emitting units to display another display image; that is, the display panel can display multiple display images, providing high display flexibility.

[0171] Figure 31 is a schematic diagram of a display device provided in an embodiment of this application. Referring to Figure 31, the display device includes a power supply component 200 and a display panel 100 as provided in the above embodiment. The power supply component 200 is connected to the display panel 100 and is used to supply power to the display panel 100.

[0172] Optionally, the display device can be an organic light-emitting diode (OLED) display device. The display device can be any suitable display device, including but not limited to mobile phones, tablets, televisions, monitors, laptops, digital photo frames, in-vehicle displays, navigators, and e-books, as well as any product or component with display functionality.

The embodiments, features, and elements disclosed in this disclosure may also be combined with any conventional features or elements to form a unique inventive scheme as defined by the claims. Any feature or element of any embodiment may also be combined with features or elements from other inventive schemes to form another unique inventive scheme as defined by the claims.

Furthermore, various modifications and changes may be made within the scope of the appended claims.

[0176] Furthermore, in describing representative embodiments, the specification may have presented methods and / or processes as a specific sequence of steps. However, the method or process should not be limited to the specific order of steps described herein, to the extent that the method or process does not depend on the specific order of steps described herein. As will be understood by those skilled in the art, other sequences of steps are also possible.

[0177] In the accompanying drawings, the size of one or more constituent elements, the thickness of layers, or areas are sometimes exaggerated for clarity. Furthermore, the drawings schematically illustrate ideal examples, and this disclosure is not limited to the shapes or numerical values ​​shown in the drawings.

[0178] The ordinal numbers such as "first," "second," and "third" used in this specification are used to avoid confusion among the constituent elements, not to limit the quantity. The term "multiple" in this disclosure refers to two or more quantities.

[0179] The thickness range of the film layer in this specification is A to B, which means that the thickness is between A and B, including the two endpoints of A and B.

[0180] In this specification, for convenience, terms such as "middle," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships in conjunction with the accompanying drawings. This is solely for the purpose of facilitating the description and simplification, and does not imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this disclosure. The positional relationships of the constituent elements may be appropriately varied depending on the orientation of the constituent elements being described. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0181] In this specification, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection via an intermediate component, or a connection within two components. Those skilled in the art will understand the meaning of these terms in this disclosure as appropriate.

[0182] In this specification, a transistor is a device that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between the drain electrode (drain terminal, drain region, or drain) and the source electrode (source terminal, source region, or source), and current can flow through the drain electrode, the channel region, and the source electrode. Note that in this specification, the channel region refers to the region through which current primarily flows.

[0183] In this specification, the first terminal of a transistor can be the drain electrode and the second terminal of a transistor can be the source electrode, or vice versa. In cases where transistors with opposite polarities are used or where the current direction changes during circuit operation, the functions of the "source electrode" and "drain electrode" are sometimes interchanged. Therefore, in this specification, the "source electrode" and "drain electrode" can be interchanged, and the "source terminal" and "drain terminal" can be interchanged.

[0184] In this specification, "connection" includes the situation where constituent elements are connected together by a component that has a certain electrical function. There are no particular limitations on the "component that has a certain electrical function," as long as it enables the transmission of electrical signals between the connected constituent elements. Examples of "components that have a certain electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other components with various functions.

[0185] In this specification, "parallel" refers to the state where the angle formed by two straight lines is greater than or equal to -10° and less than 10°, and therefore also includes the state where the angle is greater than or equal to -5° and less than 5°. Similarly, "perpendicular" refers to the state where the angle formed by two straight lines is greater than or equal to 80° and less than 100°, and therefore also includes the state where the angle is greater than or equal to 85° and less than 95°.

[0186] In this specification, the terms "film" and "layer" may be interchanged. For example, "conductive layer" may sometimes be replaced with "conductive film." Similarly, "insulating film" may sometimes be replaced with "insulating layer."

[0187] In this disclosure, "thickness" and "height" refer to the vertical distance between the surface of the film layer away from the substrate and the surface of the film layer closer to the substrate.

[0188] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
