[0081] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0082] Figure 1 It is a schematic structural diagram of a display panel provided by an embodiment of the present application. Refer to Figure 1 , the display panel 100 includes: a substrate 101, a plurality of light-emitting units 102, a plurality of first light-shielding portions 103, and a plurality of second light-shielding portions 104. Refer to Figure 1 , the substrate 101 includes a display area 101a and a peripheral area 101b surrounding the display area 101a. Refer to Figure 1 , a plurality of light-emitting units 102 are located in the display area 101a.

[0083] Figure 2 It is a partial top view of a display panel provided by an embodiment of the present application. Combining Figure 1 and Figure 2 , each light-emitting unit 102 includes a first sub-light-emitting unit 1021 and a second sub-light-emitting unit 1022 arranged along the first direction X. In the embodiments of the present application, a solid outer frame is used to represent the first sub-light-emitting unit 1021, and a dashed outer frame is used to represent the second sub-light-emitting unit 1022.

[0084] A plurality of first light-shielding portions 103 and a plurality of second light-shielding portions 104 both correspond to a plurality of light-emitting units 102. For example, the plurality of first light-shielding portions 103 and the plurality of light-emitting units 102 are in one-to-one correspondence, that is, the number of the first light-shielding portions 103 can be equal to the number of the light-emitting units 102. The plurality of second light-shielding portions 104 and the plurality of light-emitting units 102 are in one-to-one correspondence, that is, the number of the second light-shielding portions 104 can be equal to the number of the light-emitting units 102.

[0085] The first light-shielding portion 103 is located on the first side of the corresponding light-emitting unit 102, and the orthographic projection of the first 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 light-shielding portion 104 is located on the second side of the corresponding light-emitting unit 102, and the orthographic projection of the second 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.

[0086] 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.

[0087] Wherein, 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 Figure 1 and Figure 2 , the first side of the light-emitting unit 102 may refer to the left side of the light-emitting unit 102, that is, the first light-shielding portion 103 may be located on the left side of the first sub-light-emitting unit 1021 in the light-emitting unit 102. The second side of the light-emitting unit 102 may refer to the right side of the light-emitting unit 102, that is, the second light-shielding portion 104 may be located on the right side of the second sub-light-emitting unit 1022 in the light-emitting unit 102.

[0088] Optionally, referring to Figure 3 , the first side of the light-emitting unit 102 may also refer to the right side of the light-emitting unit 102, that is, the first light-shielding portion 103 may be located on the right side of the first sub-light-emitting unit 1021 in the light-emitting unit 102. The second side of the light-emitting unit 102 may also refer to the left side of the light-emitting unit 102, that is, the second light-shielding portion 104 may be located on the left side of the second sub-light-emitting unit 1022 in the light-emitting unit 102. The embodiments of the present application do not limit the left and right setting positions of the first light-shielding portion 103 and the second light-shielding portion 104. The subsequent embodiments of the present application will be described by taking the Figure 2 shown scheme as an example.

[0089] In the embodiment of the present application, since the first type of light-shielding portion 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 portion 103, and the light emitted by the first sub-light-emitting unit 1021 (such as large-angle light) will not exit from this side. At the same time, there is no light-shielding portion 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 normally exit from this side.

[0090] In addition, since the second type of light-shielding portion 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 portion 104, and the light emitted by the second sub-light-emitting unit 1022 (such as large-angle light) will not exit from this other side. At the same time, there is no light-shielding portion 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 normally exit from this other side.

[0091] Reference Figure 4 , in the plurality of light-emitting units 102 included in the display panel 100, the first sub-light-emitting units 1021 can jointly display a display screen, enabling a user to observe this display screen (hereinafter referred to as the first display screen) from the second side (such as the right side) close to the light-emitting unit 102. At the same time, in the plurality of light-emitting units 102 included in the display panel 100, the second sub-light-emitting units 1022 can jointly display another display screen, enabling a user to observe this other display screen (hereinafter referred to as the second display screen) from the first side (such as the left side) close to the light-emitting unit 102. That is to say, the display panel 100 can display multiple display screens, and the display flexibility of the display panel 100 is relatively high.

[0092] In summary, the embodiment of the present application provides a display panel, which includes a substrate, a plurality of light-emitting units, a plurality of first type of light-shielding portions, and a plurality of second type of light-shielding portions. The first type of light-shielding portion is located on one side of the first sub-light-emitting unit in the light-emitting unit, and the second type of light-shielding portion is located on the other side of the second sub-light-emitting unit in the light-emitting unit. Thereby, it can be made such that the first sub-light-emitting units of the plurality of light-emitting units in the display panel display one display screen, and the second sub-light-emitting units of the plurality of light-emitting units display another display screen, that is, the display panel can display multiple display screens, and the display flexibility of the display panel is relatively high.

[0093] In the embodiment of the present application, reference Figure 2, 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, and does not overlap with the orthographic projection of the second sub-light-emitting unit 1022 on the substrate 101 onto the reference plane C. Wherein, the reference plane C is perpendicular to the surface of the substrate 101 and parallel to the first direction X. Figure 2 The orthographic projection of the reference plane C on the substrate 101 is represented by a dashed line.

[0094] Optionally, the orthographic projection of the first type of light-shielding portion 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 portion 103, and further avoiding the light emitted by the first sub-light-emitting unit 1021 from interfering with and affecting the second display screen.

[0095] The orthographic projection of the second type of light-shielding portion 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, and does not overlap with the orthographic projection of the first sub-light-emitting unit 1021 on the substrate 101 onto the reference plane C.

[0096] Optionally, the orthographic projection of the second type of light-shielding portion 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 portion 104, and further avoiding the light emitted by the second sub-light-emitting unit 1022 from interfering with and affecting the first display screen.

[0097] In the embodiments of the present application, Figure 5 is Figure 2 a cross-sectional view along the AA' direction. Figure 6 is Figure 2 a cross-sectional view along the BB' direction. Refer to Figure 5 and Figure 6 , the display panel 100 further includes: a packaging film layer 105 located on the side of the plurality of light-emitting units 102 away from the substrate 101. At least a part of each type of light-shielding portion among the plurality of first type of light-shielding portions 103 and the plurality of second type of light-shielding portions 104 is located on the side of the packaging film layer 105 away from the substrate 101.

[0098] Refer to Figure 5 and Figure 6, the display panel 100 includes: a first light-shielding layer 106 and a first protective layer 107 which are located on the side of the encapsulation film layer 105 away from the substrate 101 and are stacked in a direction away from the substrate 101. The first light-shielding layer 106 includes a first light-shielding portion 1061 of the first type of light-shielding portion 103 and a first light-shielding portion 1061 of the 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 a first light-shielding portion 1061 located in the first light-shielding layer 106.

[0101] In the embodiment of the present application, taking the display panel 100 including the first light-shielding layer 106 and the second light-shielding layer 108 as an example, the stacking relationship and positions of the light-emitting units 102 at four different viewing angles are introduced.

[0102] Reference 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 the substrate 101, and the light-emitting device layer M includes 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.

[0103] The anode layer m1 includes a first anode portion m11 of the first sub-light-emitting unit 1021 of each light-emitting unit 102 among the plurality of light-emitting units 102, and a second anode portion m12 of the second sub-light-emitting unit 1022 of each light-emitting unit 102 among 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 the first direction X, and the first anode portion m11 and the second anode portion m12 are arranged at intervals.

[0104] The pixel defining layer m2 includes a plurality of first hollow areas m2a and a plurality of second hollow areas m2b. The plurality of first hollow areas m2a correspond to the plurality of light-emitting units 102. At least a part of the first anode portion m11 of the first sub-light-emitting unit 1021 of the corresponding light-emitting unit 102 is exposed in the first hollow area m2a. The plurality of second hollow areas m2b correspond to the plurality of light-emitting units 102. At least a part of the second anode portion m12 of the second sub-light-emitting unit 1022 of the corresponding light-emitting unit 102 is exposed in the second hollow area m2b.

[0105] The light-emitting layer m3 includes a first light-emitting portion m31 of the first sub-light-emitting unit 1021 of each light-emitting unit 102 among the plurality of light-emitting units 102, and a second light-emitting portion m32 of the second sub-light-emitting unit 1022 of each light-emitting unit 102 among the plurality of light-emitting units 102. The first light-emitting portion m31 is located in the first hollow area m2a and is connected to the first anode portion m11. The second light-emitting portion m32 is located in the second hollow area m2b and is connected to the second anode portion m12. Optionally, the first light-emitting portion m31 and the second light-emitting portion m32 may be arranged at intervals or may be connected as a whole, and the embodiments of the present application do not limit this.

[0106] The cathode layer m4 is located on the side of the first light-emitting portion m31 and the second light-emitting portion m32 away from the substrate 101, and the cathode layer m4 is connected to the first light-emitting portion m31 and the second light-emitting portion m32. That is, the cathode layer m4 can be used as a common cathode for the plurality of light-emitting units 102.

[0107] In the embodiments of the present application, with reference to Figure 14 and Figure 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 the first type of light-shielding portion 103 and a third light-shielding portion 1101 of the second type of light-shielding portion 104. Among them, the third light-shielding layer 110 may be located between the pixel defining layer m2 and the cathode layer m4.

[0108] In Figure 14In the display panel 100 shown, 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 third light-shielding portion 1101 located in the third light-shielding layer 110. 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 of the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display screens.

[0109] In Figure 15 In the display panel 100 shown, 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 third light-shielding portion 1101 located in the third light-shielding layer 110. 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, compared with the solution of one or two layers of light-shielding portions, the light-shielding effect can be further improved, and the mutual influence of different display screens of the display panel can be avoided.

[0110] In the embodiments of the present application, the above Figure 14 and Figure 15 The number of layers of the light-shielding portions included in the first type of light-shielding portion 103 is the same as the number of layers of the light-shielding portions included in the second type of light-shielding portion 104. In fact, the number of layers of the light-shielding portions included in the first type of light-shielding portion 103 and the number of layers of the light-shielding portions included in the second type of light-shielding portion 104 may also be different. For example, the first type of light-shielding portion includes two layers of light-shielding portions, and the second type of light-shielding portion includes three layers of light-shielding portions. The embodiments of the present application do not make specific limitations on this.

[0111] Optionally, when both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 include one layer of light-shielding portion, the light-shielding portion included in the first type of light-shielding portion 103 and the light-shielding portion included in the second type of light-shielding portion 104 may be located in the same layer or in 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 portions, the multiple layers of light-shielding portions included in the first type of light-shielding portion 103 and the multiple layers of light-shielding portions included in the second type of light-shielding portion 104 may be located in the same layer in one-to-one correspondence, or at least part of the multiple layers of light-shielding portions included in the first type of light-shielding portion 103 and the light-shielding portion included in the second type of light-shielding portion 104 may be located in different layers.

[0112] For example, Figure 5 the first light-shielding portion 1061 of the first type of light-shielding portion 103 shown in Figure 6 and the first light-shielding portion 1061 of the second type of light-shielding portion 104 shown in

[0113] For another example, Figure 7 the first light-shielding portion 1061 of the first type of light-shielding portion 103 shown in Figure 8 and the first light-shielding portion 1061 of the second type of light-shielding portion 104 shown in can both be located in the first light-shielding layer 106; Figure 7 the second light-shielding portion 1081 of the first type of light-shielding portion 103 shown in Figure 8 and the second light-shielding portion 1081 of the second type of light-shielding portion 104 shown in can be located in the second light-shielding layer 108. Alternatively, at least one of the first light-shielding portion and the second light-shielding portion of the first type of light-shielding portion 103 and the first light-shielding portion and the second light-shielding portion of the second type of light-shielding portion 104 are located in different layers.

[0114] In the embodiments of the present application, referring to Figure 16 and Figure 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 the first type of light-shielding portion 103 and a fourth light-shielding portion 1111 of the second type of light-shielding portion 104. Among them, the fourth light-shielding layer 111 can be located between the cathode layer m4 and the encapsulation film layer 105.

[0115] In Figure 16 the shown display panel 100, both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 can include: a first light-shielding portion 1061 located in the first light-shielding layer 106, and a fourth light-shielding portion 1111 located in the fourth light-shielding layer 111. 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 of the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display pictures. Alternatively, the number of layers of the light-shielding portions included in the first type of light-shielding portion 103 can be different from the number of layers of the second light-shielding portion.

[0116] In Figure 17 the shown display panel 100, both the first type of light-shielding portion 103 and the second type of light-shielding portion 104 can 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, compared with the scheme of one or two layers of light-shielding portions, the light-shielding effect can be further improved, and the mutual influence of different display pictures of the display panel can be avoided. Alternatively, the number of layers of the light-shielding portions included in the first type of light-shielding portion 103 can be different from the number of layers of the second light-shielding portion.

[0117] In the embodiments of the present application, referring to Figure 18 and Figure 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.

[0118] In Figure 18 In the shown display panel 100, the first type of light-shielding portion 103 and the second type of light-shielding portion 104 can both include: the 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 of the sub-light-emitting unit 102, which can improve the blocking effect and ensure the display effect of different display screens.

[0119] In Figure 19 In the shown display panel 100, the first type of light-shielding portion 103 and the second type of light-shielding portion 104 can both include: the first light-shielding portion 1061 located in the first light-shielding layer 106, the second light-shielding portion 1081 located in the second light-shielding layer 108, and the fifth light-shielding portion 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 portion 103 and the second type of light-shielding portion 104 include three layers of light-shielding portions, compared with the scheme of one or two layers of light-shielding portions, the light-shielding effect can be further improved, and the mutual influence of different display screens of the display panel 100 can be avoided.

[0120] In the embodiment of the present application, the display panel 100 further includes more layers of light-shielding layers, thereby improving the light-shielding effect on the light emitted by the sub-light-emitting unit 102. The embodiment of the present application does not specifically limit the number of light-shielding layers included in the display panel 100.

[0121] Optionally, the setting methods of the first type of light-shielding portion 103 and the second type of light-shielding portion 104 listed in the embodiment of the present application can be combined as needed. For example, the first type of light-shielding portion 103 can be Figure 15 the first type of light-shielding portion shown. The second type of light-shielding portion 104 can be Figure 16 the second type of light-shielding portion shown.

[0122] Optionally, in order to ensure the light-shielding effect, the distance range between the light-shielding layer farthest from the substrate 101 and the light-shielding layer closest to the substrate 101 in the display panel can be 5 μm (micrometers) to 50 μm.

[0123] For example Figure 16In the display panel 100 shown, 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 farthest from the substrate 101 in the display panel 100, and the fourth light-shielding layer 111 is the light-shielding layer closest to the substrate 101 in the display panel 100. The distance h between the first light-shielding layer 106 and the fourth light-shielding layer 111 can be 10 μm.

[0124] For example Figure 17 In the display panel 100 shown, 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 farthest from the substrate 101 in the display panel 100, and the fourth light-shielding layer 111 is the light-shielding layer closest to the substrate 101 in the display panel 100. The distance h between the second light-shielding layer 108 and the fourth light-shielding layer 111 can be 40 μm.

[0125] For example Figure 19 In the display panel 100 shown, the display panel 100 includes a first light-shielding layer 106, a second light-shielding layer 108, and a fifth light-shielding layer 112 (the pixel defining layer m2 made of a light-shielding material). The second light-shielding layer 108 is the light-shielding layer farthest from the substrate 101 in the display panel 100, and the fifth light-shielding layer 112 is the light-shielding layer closest to the substrate 101 in the display panel 100. The distance between the second light-shielding layer 108 and the fifth light-shielding layer 112 can be 45 μm.

[0126] In the embodiments of the present application, referring to Figure 20 , the display panel 100 further includes: a plurality of third types of light-shielding portions 113. The plurality of third types of light-shielding portions 113 are correspondingly arranged with at least some of the plurality of light-emitting units 102. The third type of light-shielding portion 113 is located on the third side of the corresponding light-emitting unit 102, and the third side and the light-emitting unit 102 are arranged along the first direction X. Optionally, each light-emitting unit 102 may correspond to one third type of light-shielding portion 113, and the third type of light-shielding portion 113 may be located on the third side of the light-emitting unit 102. Or, each light-emitting unit 102 may correspond to two third types of light-shielding portions 113, one of the third type of light-shielding portions 113 is located on the third side of the light-emitting unit 102, and the other third type of light-shielding portion 113 is located between the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022.

[0127] When the display panel 100 is applied to in-vehicle display, the light emitted from the light-emitting unit 102 from the upper side (or upper viewing angle) can be blocked by setting the third type of light-shielding portion 113, so as to prevent the light from being projected onto the in-vehicle windshield, reduce the influence on the driver, and improve driving safety.

[0128] Optionally, the third side of the light-emitting unit 102 may refer to the upper side of the light-emitting unit 102. For example, a plurality of third light-shielding portions 113 may be correspondingly disposed with a plurality of light-emitting units 102 in the upper half of the display area 101a of the display panel 100. That is, a plurality of third light-shielding portions 113 are located on the upper side of a plurality of light-emitting units 102 in the upper half. Alternatively, a plurality of third light-shielding portions 113 may be correspondingly disposed with a plurality of light-emitting units 102 in the display panel 100. That is, each third light-shielding portion 113 may be located on the upper side of a corresponding light-emitting unit 102.

[0129] In the embodiment of the present application, referring to Figure 21 shows three light-emitting units 102 (red light-emitting unit R, green light-emitting unit G, and blue light-emitting unit B), and correspondingly, there may be three data lines corresponding to the three light-emitting units 102. Referring to Figure 22 shows three light-emitting units 102, 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 then six data lines need to be designed to correspond to the six sub-light-emitting units. That is, 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 for providing data signals will also double, and then the number of chip-on-film (COF) connected to the data lines will double, and the interval of different bonding pins of the COF will also be greatly compressed, resulting in problems such as short circuit or open circuit.

[0130] 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 pole, and a second pole.

[0131] The gate of the first transistor T1 is connected to the first signal selection control line 1141, the first pole of the first transistor T1 is connected to the signal input line 115, and the second pole 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 pole of the second transistor T2 is connected to the signal input line 115, and the second pole of the second transistor T2 is connected to the second data signal line 117.

[0132] Among them, the first signal selection control line 1141 provides a first control signal for the gate of the first transistor T1, and the first transistor T1 is turned 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, and the first target sub-light-emitting unit is used to receive the data signal 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 for the gate of the second transistor T2, and the second transistor T2 is turned 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, and the second target sub-light-emitting unit is used to receive the data signal 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.

[0133] Optionally, the signal input line 115 may be connected to the first target sub-light-emitting unit and the second target sub-light-emitting unit. Moreover, the first target sub-light-emitting unit and the second target sub-light-emitting unit connected to the signal input line 115 may be the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 in the same light-emitting unit 102. Alternatively, the first target sub-light-emitting unit and the second target sub-light-emitting unit may be sub-light-emitting units 102 in different light-emitting units 102.

[0134] In the embodiment of the present application, the first pole of the first transistor T1 connected to the first target sub-light-emitting unit and the first pole of the second transistor T2 connected to the second target sub-light-emitting unit may be connected to the same signal input line 115. Thus, when the first transistor T1 is in the on state, 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 in the on state, 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. Furthermore, the signal input line 115 can transmit the data signal to the corresponding sub-light-emitting unit 102 through the transistor in the on state. That is to say, the multiplexer 114 can be a 1:2 driving scheme. In this case, the number of signal input lines 115 can be reduced, and then the number of COFs connected to the signal input line 115 can be reduced, and the interval between different bonding pins of the COF can also be appropriately increased, reducing the probability of short circuit or open circuit.

[0135] Optionally, refer 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 different from each other.

[0136] Optionally, the first color may be red (R), the second color may be green (G), and the third color may be blue (B). The light-emitting unit 102a of the first color may be a red light-emitting unit 102-R. The light-emitting unit 102b of the second color may be a green light-emitting unit 102-G. The light-emitting unit 102c of the third color may be a blue light-emitting unit 102-B.

[0137] Alternatively, the first color is red, the second color is blue, and the third color is green. The light-emitting unit 102a of the first color may be a red light-emitting unit 102-R. The light-emitting unit 102b of the second color may be a blue light-emitting unit 102-B. The light-emitting unit 102c of the third color may be a green light-emitting unit 102-G.

[0138] Wherein, one light-emitting unit 102a of the first color, one light-emitting unit 102b of the second color, and one light-emitting unit 102c of the third color constitute a light-emitting unit group Z. That is to say, 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.

[0139] Reference Figure 23 , taking one 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 arranged with the three first transistors T1 and the three second transistors T2. That is, each of the three signal input lines 115 is arranged with one first transistor T1 and one second transistor T2.

[0140] Among them, each of the three signal input lines 115 is connected to a corresponding first transistor T1 and a corresponding second transistor T2. The second poles of the three first transistors T1 are correspondingly connected to three first data signal lines 116. The three first data signal lines 116 are respectively connected to the first sub-light emitting units 1021 of the light emitting units 102a of the first color in the light emitting unit group Z, the first sub-light emitting units 1021 of the light emitting units 102b of the second color in the light emitting unit group Z, and the first sub-light emitting units 1021 of the light emitting units 102c of the third color in the light emitting unit group Z. The second poles of the three second transistors T2 are correspondingly connected to three second data signal lines 117. The three second data signal lines 117 are respectively connected to the second sub-light emitting units 1022 of the light emitting units 102a of the first color in the light emitting unit group Z, the second sub-light emitting units 1022 of the light emitting units 102b of the second color in the light emitting unit group Z, and the second sub-light emitting units 1022 of the light emitting units 102c of the third color in the light emitting unit group Z.

[0141] Reference Figure 23 , the first signal input line 115 among 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 light emitting unit 102a of the first color.

[0154] 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. Moreover, the first target sub-light-emitting unit, the second target sub-light-emitting unit, and the third target sub-light-emitting unit connected by the signal input line 115 can be different sub-light-emitting units 102.

[0155] Reference 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 two signal input lines 115 are correspondingly arranged with the two first transistors T1, the two second transistors T2, and the two third transistors T3. That is, each of the two signal input lines 115 is arranged with a first transistor T1, a second transistor T2, and a third transistor T3.

[0156] Among them, 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 poles of the two first transistors T1 are correspondingly connected to the two first data signal lines 116, and the two first data signal lines 116 are respectively connected to the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 of the light-emitting unit 102a of the first color in the light-emitting unit group Z.

[0157] Reference Figure 28, the first signal input line 115 among the two signal input lines 115 is connected to the first sub-light emitting units 1021 of the light emitting units 102a of the first color, the first sub-light emitting units 1021 of the light emitting units 102b of the second color, and the first sub-light emitting units 1021 of the light emitting units 102c of the third color.

[0158] Exemplarily, in Figure 28 In the scheme shown, the two first transistors T1 are respectively connected to the first sub-light emitting unit 1021 and the second sub-light emitting unit 1022 of the light emitting unit 102a of the first color. Correspondingly, two first data signal lines 116 are connected to the two first transistors T1 correspondingly.

Correspondingly, two third data signal lines 118 are connected to the two third transistors T3 correspondingly.

[0159] In the embodiment of the present application, for the 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 represent that the number of signal input lines 115 and the number of data signal lines are 1:3.

[0160] In the above embodiment of the present application, taking the light emitting unit being divided into two sub-light emitting units as an example, it is used to implement the dual-view display function of the display panel. In fact, 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 of the display panel can also be achieved. Exemplarily, the light emitting unit can be divided into two sub-light emitting units, four sub-light emitting units, six sub-light emitting units, and so on.

[0161] Optionally, in addition to implementing the dual-view display function, the display panel can also implement the functions of active privacy protection and shared display. The light-emitting unit can be divided into an even or odd number of sub-light-emitting units. For example, the light-emitting unit can be divided into a shared sub-light-emitting unit and multiple privacy protection 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. Assume that sub-light-emitting unit a1 is the shared sub-light-emitting unit, and sub-light-emitting unit a2 and sub-light-emitting unit a3 can be privacy protection sub-light-emitting units. Sub-light-emitting unit a1 can emit light when implementing the shared display function, and sub-light-emitting unit a2 and sub-light-emitting unit a3 can emit light when implementing the dual-view display, active privacy protection, and shared display functions.

[0162] Sub-light-emitting unit a2 can provide a display function of displaying to the first side (the first side can be the left side) and preventing peeping to the second side (the second side can be the right side), and sub-light-emitting unit a3 can provide a display function of displaying to the second side (the second side can be the right side) and preventing peeping to the first side (the first side can be the left side). When sub-light-emitting unit a2 and sub-light-emitting unit a3 emit light based on the same picture, they can provide the shared display function.

[0163] Take a light-emitting unit group Z including 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 as an example.

[0164] Assume that the first sub-light-emitting unit 1021 and the second sub-light-emitting unit 1022 included in the light-emitting units of the three colors are all privacy protection sub-light-emitting units. When the display panel is in the privacy protection display mode or the dual-view display mode, the first sub-light-emitting unit 1021 in the light-emitting units of the three colors can all display the first display picture to the second side without displaying the first display picture to the first side, and the second sub-light-emitting unit 1022 in the light-emitting units of the three colors can all display the second display picture to the first side without displaying the second display picture to the second side.

[0165] Assume that the first sub-light-emitting units 1021 included in the light-emitting units of three colors are all anti-peeking sub-light-emitting units, and the second sub-light-emitting units 1022 included in the light-emitting units of three colors are all shared sub-light-emitting units. When the display panel is in the shared display mode, the second sub-light-emitting units 1022 included in the light-emitting units of three colors can be made to emit light, or the first sub-light-emitting units 1021 and the second sub-light-emitting units 1022 included in the light-emitting units of three colors can be made to emit light simultaneously. In the shared display mode, the first sub-light-emitting units 1021 and the second sub-light-emitting units 1022 included in the light-emitting units of three colors can display the same picture. When the display panel is in the anti-peeking display mode, the first sub-light-emitting units 1021 included in the light-emitting units of three colors, which are all anti-peeking sub-light-emitting units, can be made to emit light, and the second sub-light-emitting units 1022 included in the light-emitting units of three colors do not emit light.

[0166] When a plurality of sub-light-emitting units obtained by dividing a light-emitting unit include shared sub-light-emitting units, a light-shielding portion may not be provided on the side of the shared sub-light-emitting unit, so that the light emitted by the shared sub-light-emitting unit will not be blocked by the light-shielding portion.

[0167] In the embodiments of the present application, the arrangement manner of the light-emitting units in the drawings is only an example. In fact, the light-emitting units can also be arranged in other ways, and the embodiments of the present application do not specifically limit the arrangement manner of the plurality of light-emitting units in the display panel. For example, the plurality of light-emitting units included in the display panel can be arranged in RGB arrangement, Pentile arrangement, diamond arrangement, Delta arrangement, and so on.

[0168] Optionally, the light-shielding portions between two adjacent light-emitting units in the second direction Y can be shared. Taking Figure 2 the shown arrangement manner as an example, between the second sub-light-emitting unit 1022 in the light-emitting unit 102b of the second color and the first sub-light-emitting unit 1021 in the light-emitting unit 102c of the third color, there are provided: a second type of light-shielding portion 104 corresponding to the light-emitting unit 102b of the second color, and a first type of light-shielding portion 103 corresponding to the light-emitting unit 102c of the third color.

[0169] Refer to Figure 29 and the second type of light-shielding portion 104 corresponding to the light-emitting unit 102b of the second color and the first type of light-shielding portion 103 corresponding to the light-emitting unit 102c of the third color can be connected together to form an integral light-shielding portion. That is, there can be no gap between the second type of light-shielding portion 104 corresponding to the light-emitting unit 102b of the second color and the first type of light-shielding portion 103 corresponding to the light-emitting unit 102c of the third color.

[0170] Or, refer to Figure 30, since the first type of light-shielding portion 103 corresponding to the light-emitting unit 102c of the third color is disposed on the second side of the second sub-light-emitting unit 1022 of the light-emitting unit 102b of the second color, it can be reused as the second type of light-shielding portion 104 corresponding to the light-emitting unit 102b of the second color. That is, the second type of light-shielding portion 104 corresponding to the light-emitting unit 102b of the second color can be omitted, and the first type of light-shielding portion 103 corresponding to the light-emitting unit 102c of the third color can be directly used to block the light emitted from the second sub-light-emitting unit 1022 of the light-emitting unit 102b of the second color to the second side. This can make the light-shielding portion disposed between the two light-emitting units occupy a smaller space, which is beneficial to the realization of high-resolution products.

[0171] In summary, the embodiment of the present application provides a display panel, which includes a substrate, a plurality of light-emitting units, a plurality of first types of light-shielding portions, and a plurality of second types of light-shielding portions. The first type of light-shielding portion is located on one side of the first sub-light-emitting unit in the light-emitting unit, and the second type of light-shielding portion is located on the other side of the second sub-light-emitting unit in the light-emitting unit. Thus, the first sub-light-emitting units of the plurality of light-emitting units in the display panel can display one display picture, and the second sub-light-emitting units of the plurality of light-emitting units can display another display picture, that is, the display panel can display multiple display pictures, and the display flexibility of the display panel is relatively high.

[0172] Figure 31 is a schematic structural diagram of a display device provided by an embodiment of the present application. Refer to Figure 31 , the display device includes: a power supply component 200 and the display panel 100 provided in the above embodiment. The power supply component 200 is connected to the display panel 100 for supplying power to the display panel 100.

[0174] Since the display device may have substantially the same technical effects as the display panel described in the previous embodiments, for the sake of simplicity, the technical effects of the display device are not repeated here.

[0175] The present disclosure describes multiple embodiments, but the description is exemplary rather than restrictive, and it will be apparent to those of ordinary skill in the art that there can be more embodiments and implementation solutions within the scope covered by the embodiments described in the present disclosure. Although many possible combinations of features are shown in the drawings and discussed in the detailed description, many other combinations of the disclosed features are also possible. Unless specifically restricted, any feature or element of any embodiment can be used in combination with any other feature or element in any other embodiment, or can replace any other feature or element in any other embodiment.

[0176] The present disclosure includes and contemplates combinations with features and elements known to those of ordinary skill in the art. The embodiments, features, and elements already disclosed in the present disclosure can also be combined with any conventional features or elements to form unique inventive solutions defined by the claims. Any feature or element of any embodiment can also be combined with features or elements from other inventive solutions to form another unique inventive solution defined by the claims. Therefore, it should be understood that any feature shown and / or discussed in the present disclosure can be implemented alone or in any suitable combination. Therefore, the embodiments are not subject to other limitations except those made in accordance with the appended claims and their equivalents. In addition, various modifications and changes can be made within the scope of the appended claims.

[0177] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not depend on the specific order of the steps described herein, the method or process should not be limited to the specific order of steps described. As will be understood by those of ordinary skill in the art, other step sequences are possible. Therefore, the specific order of steps set forth in the specification should not be construed as a limitation on the claims. In addition, the claims directed to the method and / or process should not be limited to performing their steps in the order written, and those skilled in the art can easily understand that these orders can vary and still remain within the spirit and scope of the embodiments of the present disclosure.

[0178] In the drawings, sometimes for clarity, the sizes of one or more constituent elements, the thicknesses of layers, or regions are exaggerated. In addition, the drawings schematically show ideal examples, and one aspect of the present disclosure is not limited to the shapes, values, etc. shown in the drawings.

[0179] The ordinal numbers such as "first", "second", "third", etc. in this specification are set to avoid confusion of constituent elements and are not intended to limit in terms of quantity. "Multiple" in the present disclosure means two or more in number.

[0180] The thickness range of the film layer in this specification from A to B is used to represent that the thickness is between A and B, including the two end values of A and B.

[0181] In this specification, for convenience, terms indicating orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are used to describe the positional relationship of the constituent elements with reference to the accompanying drawings. This is only for the convenience of describing this specification and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present disclosure. The positional relationship of the constituent elements changes appropriately according to the direction of the described constituent elements. Therefore, it is not limited to the terms described in the specification and can be replaced appropriately according to the situation.

[0182] In this specification, unless otherwise clearly defined and limited, the terms "mounted", "connected", and "coupled" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate member, or the internal communication of two elements. For those of ordinary skill in the art, the meanings of the above terms in the present disclosure can be understood according to the situation.

[0183] In this specification, a transistor refers to an element including at least three terminals: a gate electrode, a drain electrode, and a source electrode. The transistor has a channel region between the drain electrode (drain electrode terminal, drain region, or drain) and the source electrode (source electrode 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 where current mainly flows.

[0184] In this specification, the first pole of the transistor can be the drain electrode, the second pole of the transistor can be the source electrode, or the first pole of the transistor can be the source electrode, and the second pole of the transistor can be the drain electrode. In the case of using transistors with opposite polarities or when the current direction changes during circuit operation, etc., 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 with each other, and the "source terminal" and "drain terminal" can be interchanged with each other.

[0185] In this specification, "connection" includes the case where the constituent elements are connected together through an element having a certain electrical effect. The "element having a certain electrical effect" is not particularly limited as long as it can transmit the electrical signal between the constituent elements to be connected. Examples of the "element having a certain electrical effect" include not only electrodes and wirings, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having various functions.

[0186] In this specification, "parallel" means a state where the angle formed by two straight lines is more than -10° and less than 10°, and thus also includes a state where the angle is more than -5° and less than 5°. In addition, "perpendicular" means a state where the angle formed by two straight lines is more than 80° and less than 100°, and thus also includes a state where the angle is more than 85° and less than 95°.

[0187] In this specification, "film" and "layer" can be interchanged with each other. For example, sometimes "conductive layer" can be changed to "conductive film". Similarly, sometimes "insulating film" can be changed to "insulating layer".
