[0002] As display technology expands into high-privacy applications, such as mobile electronic devices used in public places or financial and office terminals, privacy-protecting display panels have become an important research and development direction. The core advantage of privacy-protecting display panels is that they achieve controllable viewing angles through optical technology, effectively protecting screen information privacy. Content is clearly visible only from a specific angle directly in front, while the screen appears blurry or black from side views, preventing information leakage in public transportation, offices, shopping malls, and other similar scenarios.

[0047] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0048] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods and means well-known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0050] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0051] In the field of active privacy protection technology, to achieve dynamic switching between shared display mode and privacy display mode, for example, referring to... Figure 1 The diagram shows a top view of the display panel. In related art display panels, shared pixel SP1 and privacy pixel SP2 are separated and spaced apart. By driving shared pixel SP1 and privacy pixel SP2 separately, dynamic switching between shared display mode and privacy display mode is achieved. For example, see [reference needed]. Figure 2The schematic diagram shown is a top view of the display panel. The related technology's display panel includes multiple shared light-emitting devices 210 and multiple electrochromic devices 10, which are spaced apart along a direction parallel to the plane of the substrate 100. In shared display mode, the electrochromic devices 10 are highly transparent, allowing light to escape over a wide viewing angle. In privacy display mode, the electrochromic devices 10 are converted to a low-transparency or opaque state, thereby limiting the light propagation angle. In both of these schemes, the display panel has a low resolution and unsatisfactory display effect in both shared and privacy display modes.

[0052] In view of the above, the first aspect of this disclosure provides a display panel, referring to Figure 3 and Figure 4 The diagram shows a top view of the display panel structure and... Figures 5 to 20 The diagram shows a cross-sectional structure of the display panel, which includes a substrate 100, a shared light-emitting layer 200, and a privacy light-emitting layer 300.

[0053] For example, the shared light-emitting layer 200 is located on one side of the substrate 100, and the shared light-emitting layer 200 includes a plurality of shared light-emitting devices 210; the privacy light-emitting layer 300 is located on the same side of the substrate 100 as the shared light-emitting layer 200, and the privacy light-emitting layer 300 includes a plurality of privacy light-emitting devices 310; at least a portion of the orthogonal projection of the shared light-emitting device 210 on the substrate 100 surrounds the orthogonal projection of the corresponding privacy light-emitting device 310 on the substrate 100, and / or, at least a portion of the orthogonal projection of the privacy light-emitting device 310 on the substrate 100 surrounds the orthogonal projection of the corresponding shared light-emitting device 210 on the substrate 100.

[0054] For example, the orthographic projection of the shared light-emitting device 210 on the substrate 100 surrounds the orthographic projection of the corresponding privacy light-emitting device 310 on the substrate 100.

[0055] For example, the orthographic projection of the privacy light-emitting device 310 on the substrate 100 surrounds the orthographic projection of the corresponding shared light-emitting device 210 on the substrate 100.

[0056] According to the display panel provided in the embodiments of this disclosure, at least a portion of the orthogonal projection of the shared light-emitting device 210 on the substrate 100 surrounds the orthogonal projection of the corresponding privacy light-emitting device 310 on the substrate 100, or at least a portion of the orthogonal projection of the privacy light-emitting device 310 on the substrate 100 surrounds the orthogonal projection of the corresponding shared light-emitting device 210 on the substrate 100, which makes the pixel density or resolution of the display panel higher and helps to reduce the resolution difference of the display panel in the shared display mode and the privacy display mode; in addition, when switching between the lighting states of the shared light-emitting device 210 and the privacy light-emitting device 310, the change in brightness and resolution perceived by the user at the same screen position is small, and the visual experience is consistent and uniform.

[0057] It should be noted that the privacy light-blocking light-blocking device 310 corresponding to the shared light-emitting device 210 refers to the privacy light-blocking light-blocking device 310 whose orthographic projection has a surrounding relationship with the shared light-emitting device 210. That is, when at least a portion of the orthographic projection of the shared light-emitting device 210 on the substrate 100 surrounds the orthographic projection of the privacy light-blocking device 310 on the substrate 100, or when at least a portion of the orthographic projection of the privacy light-blocking device 310 on the substrate 100 surrounds the orthographic projection of the shared light-emitting device 210 on the substrate 100, the privacy light-blocking device 310 is the privacy light-blocking light-blocking device 310 corresponding to the shared light-emitting device 210. The shared light-emitting device 210 corresponding to the privacy light-blocking device 310 can be referred to the above explanation and will not be elaborated further.

[0058] It is understood that the shared light-emitting device 210 and the privacy light-emitting device 310 can be driven separately. For example, the shared light-emitting device 210 and the privacy light-emitting device 310 can be driven independently through different pixel circuits, or they can be driven using the same pixel circuit.

[0059] In one embodiment, refer to Figure 27 The schematic diagram of the cross-sectional structure of the substrate shown illustrates that the substrate 100 includes a pixel circuit (not shown) and a gating component 110. The gating component 110 is connected to the pixel circuit and is also connected to both the shared light-emitting device 210 and the privacy light-emitting device 310. The gating component 110 is used to selectively drive either the shared light-emitting device 210 or the privacy light-emitting device 310. Thus, either the shared light-emitting device 210 or the privacy light-emitting device 310 can be driven by the same pixel circuit. For example, when the privacy light-emitting device 310 needs to be lit, the gating component 110 connects the privacy light-emitting device 310 to the pixel circuit, while the shared light-emitting device 210 is not connected to the pixel circuit, and the shared light-emitting device 210 is not lit. Conversely, when the shared light-emitting device 210 needs to be lit, the gating component 110 connects the shared light-emitting device 210 to the pixel circuit, while the privacy light-emitting device 310 is not connected to the pixel circuit, and the privacy light-emitting device 310 is not lit.

[0060] Optionally, the shared light-emitting device 210 and the corresponding privacy-protecting light-emitting device 310 are connected to the same gating component 110. Thus, the shared light-emitting device 210 or the corresponding privacy-protecting light-emitting device 310 can be illuminated through the same gating component 110, thereby achieving the switching between privacy-protecting display mode and shared display mode. It can be understood that one gating component 110 is electrically connected to one pixel circuit; therefore, the switching between privacy-protecting display mode and shared display mode can be achieved through one pixel circuit. The pixel circuit in the substrate 100 hardly needs to be changed; simply adding the gating component 110 between the pixel circuit and the shared light-emitting device 210 and the corresponding privacy-protecting light-emitting device 310 is sufficient to achieve the switching between privacy-protecting display mode and shared display mode.

[0061] Optionally, the gating component 110 includes a first transistor 111 and a second transistor 112. The pixel circuit is connected to the shared light-emitting device 210 through the first transistor 111, and the pixel circuit is connected to the privacy light-emitting device 310 through the second transistor 112. By controlling the first transistor 111 and the second transistor 112 to turn on or off, the pixel circuit can drive the shared light-emitting device 210 or the privacy light-emitting device 310 respectively.

[0062] For example, the 7T1C pixel circuit will be used as an example for explanation, referring to... Figure 28 The schematic diagram shown illustrates the pixel circuit and gating component 110. The pixel circuit includes seven transistors (T1 to T7) and a storage capacitor (Cst). The pixel circuit includes: a first power supply line VDD, a second power supply line VSS, a first reference voltage line Vref1, a data line Vdata, a first transistor T5, a second transistor T2, a third transistor T3 (composed of a dual-gate structure formed by connecting the first sub-transistor T3-1 and the second sub-transistor T3-2 in series), a fourth transistor T4 (composed of a dual-gate structure formed by connecting the first sub-transistor T4-1 and the second sub-transistor T4-2 in series), a sixth transistor T6, a seventh transistor T7, and a storage capacitor Cst. It should be noted that the transistors can be thin-film transistors, and the first and second terminals can be source and drain terminals and are interchangeable.

[0063] For example, the gate of the first transistor 111 can be connected to a gate in panel (GIP) circuit, and the gate of the second transistor 112 can be connected to the GIP circuit.

[0064] Optionally, the shared light-emitting device 210 includes a first electrode 211, a first light-emitting structure 212, and a second electrode 213 stacked together, with the first electrode 211 located on the side of the first light-emitting structure 212 close to the substrate 100.

[0065] For example, one of the first electrode 211 and the second electrode 213 is a shared anode, and the other of the first electrode 211 and the second electrode 213 is a shared cathode. For instance, the first electrode 211 is a shared anode, and the second electrode 213 is a shared cathode.

[0066] For example, the first light-emitting structure 212 includes a first hole injection layer, a first hole transport layer, a first electron blocking layer, a first light-emitting material layer, a first hole blocking layer, a first electron transport layer, and a first electron injection layer stacked along a direction away from the substrate 100. The first light-emitting structure 212 may include one first light-emitting material layer, or a stacked light-emitting structure including multiple first light-emitting material layers.

[0067] Optionally, the privacy light-emitting device 310 includes a stacked third electrode 311, a second light-emitting structure 312, and a fourth electrode 313, with the third electrode 311 located on the side of the second light-emitting structure 312 close to the substrate 100.

[0068] For example, one of the third electrode 311 and the fourth electrode 313 is a privacy anode, and the other of the third electrode 311 and the fourth electrode 313 is a privacy cathode. For example, the third electrode 311 is a privacy anode, and the fourth electrode 313 is a privacy cathode.

[0069] For example, the second light-emitting structure 312 includes a second hole injection layer, a second hole transport layer, a second electron blocking layer, a second light-emitting material layer, a second hole blocking layer, a second electron transport layer, and a second electron injection layer stacked along a direction away from the substrate 100. The second light-emitting structure 312 may include one second light-emitting material layer, or a stacked light-emitting structure including multiple second light-emitting material layers.

[0070] Optionally, the first transistor 111 is electrically connected to the first electrode 211, and the second transistor 112 is electrically connected to the third electrode 311. Exemplarily, the substrate 100 further includes a planarization layer 120. The planarization layer 120 has a first via and a second via, with the first electrode 211 electrically connected to the first transistor 111 through the first via, and the third electrode 311 electrically connected to the second transistor 112 through the second via.

[0071] Optionally, the second electrode 213 and the fourth electrode 313 are disposed in the same layer.

[0072] It should be noted that the co-layer arrangement of the second electrode 213 and the fourth electrode 313 can be interpreted in a broad sense. For example, it can be understood as the second electrode 213 and the fourth electrode 313 being located in the same layer, or it can be understood as the second electrode 213 and the fourth electrode 313 being prepared through the same process.

[0073] In one embodiment, refer to Figure 5 and Figure 6 The shared light-emitting layer 200 and the privacy light-emitting layer 300 are set on the same layer.

[0074] It is understandable that the shared light-emitting layer 200 and the privacy light-emitting layer 300 being set in the same layer should be interpreted broadly. It can be understood that the shared light-emitting layer 200 and the privacy light-emitting layer 300 are located in the same layer, or it can be understood that the shared light-emitting layer 200 and the privacy light-emitting layer 300 are prepared through the same preparation process.

[0075] Optionally, the display panel further includes: a first pixel defining layer 410 located on one side of the substrate 100, the first pixel defining layer 410 enclosing a plurality of shared pixel openings GX and a plurality of privacy pixel openings FK, at least a portion of the shared light-emitting device 210 being located in the shared pixel opening GX, and at least a portion of the privacy light-emitting device 310 being located in the privacy pixel opening FK. At least a portion of the shared pixel opening GX surrounds the corresponding privacy pixel opening FK (see reference). Figure 5 ), and / or, at least a portion of the privacy pixel opening FK surrounds the corresponding shared pixel opening GX (see reference ). Figure 6 ).

[0076] Optionally, the area of ​​the shared pixel opening GX projected onto the substrate 100 is equal to the area of ​​the corresponding privacy pixel opening FK projected onto the substrate 100. Therefore, in both the shared display mode and the privacy display mode, the resolution of the display panel is the same, and when switching between the shared light-emitting device 210 and the privacy light-emitting device 310, the brightness and resolution perceived by the user at the same screen position are almost unchanged, resulting in a consistent and uniform visual experience.

[0077] Optionally, the color of the shared light-emitting device 210 is the same as the color of the corresponding privacy light-emitting device 310. Therefore, when switching between the lit states of the shared light-emitting device 210 and the privacy light-emitting device 310, the brightness and resolution perceived by the user at the same screen position remain almost unchanged, resulting in a consistent and uniform visual experience. If the color of the shared light-emitting device 210 is different from the color of the corresponding privacy light-emitting device 310, when switching between the lit states of the shared light-emitting device 210 and the privacy light-emitting device 310, the displayed image perceived by the user at the same screen position will exhibit greater abruptness, resulting in a relatively poor visual experience.

[0078] Optionally, the first electrode 211 and the third electrode 311 are arranged in the same layer. The meaning of the first electrode 211 and the third electrode 311 being arranged in the same layer can be referred to the meaning of the second electrode 213 and the fourth electrode 313 being arranged in the same layer, and will not be elaborated further here.

[0079] It should be noted that the first electrode 211 and the third electrode 311 are electrically insulated from each other, or the first electrode 211 and the third electrode 311 are spaced apart.

[0080] Optionally, the first pixel defining layer 410 further encloses a plurality of first openings 411, and the display panel further includes a light-shielding structure 500, at least a portion of which is located within the first openings 411. For example, see reference to Figure 5 At least a portion of the shared pixel opening GX surrounds the corresponding privacy pixel opening FK, and the first opening 411 is located between the shared pixel opening GX and the privacy pixel opening FK. For example, see reference... Figure 6 At least a portion of the privacy pixel opening FK surrounds the corresponding shared pixel opening GX, with the first opening 411 located on the side of the privacy pixel opening FK closest to and furthest from the shared pixel opening GX. Thus, the light emitted by the privacy light-emitting device 310 is blocked by the light-shielding structure 500, preventing some light from escaping at larger viewing angles, allowing for clear viewing of the display image at specific angles, while the display image appears black beyond those specific angles.

[0081] For example, the first opening 411 is located on the side of the privacy pixel opening FK that is close to and far from the shared pixel opening GX. This can mean that the first opening 411 is located on both sides of the privacy pixel opening FK that are opposite to each other, and the first opening 411 is located on the outer periphery of the shared pixel opening GX.

[0082] Optionally, along a direction perpendicular to the plane of the substrate 100, the height of the light-shielding structure 500 is greater than or equal to the thickness of the first pixel defining layer 410. Therefore, the light-shielding structure 500 has a better light-blocking effect.

[0083] For example, the distance from the end of the light-shielding structure 500 away from the substrate 100 to the substrate 100 is greater than or equal to the distance from the surface of the first pixel defining layer 410 away from the substrate 100 to the substrate 100; the distance from the end of the light-shielding structure 500 near the substrate 100 to the substrate 100 is equal to the distance from the surface of the first pixel defining layer 410 near the substrate 100 to the substrate 100.

[0084] For example, the material of the light-shielding structure 500 can be black organic adhesive.

[0085] It is understandable that when at least a portion of a shared pixel opening GX surrounds a corresponding privacy pixel opening FK, the spacing between adjacent shared pixel openings GX is relatively small. This small spacing necessitates higher fabrication precision when manufacturing the light-emitting device and the first pixel defining layer 410.

[0086] Optionally, refer to Figure 7 and Figure 8The display panel also includes an isolation structure 600 located on the side of the first pixel defining layer 410 facing away from the substrate 100. The isolation structure 600 encloses a plurality of first isolation openings 610 and a plurality of second isolation openings 620. The orthographic projection of the shared pixel opening GX on the substrate 100 lies within the orthographic projection range of the corresponding first isolation opening 610 on the substrate 100, and the orthographic projection of the privacy pixel opening FK on the substrate 100 lies within the orthographic projection range of the corresponding second isolation opening 620 on the substrate 100. The isolation structure 600 helps to improve the manufacturing precision and yield of the shared light-emitting device 210 and the privacy light-emitting device 310, and is more conducive to obtaining a display panel with better performance.

[0087] Optionally, the orthographic projection of the light-shielding structure 500 on the substrate 100 is located within the orthographic projection range of the isolation structure 600 on the substrate 100.

[0088] For example, refer to Figure 9 and Figure 10 The isolation structure 600 is reused as the light-shielding structure 500. It can be understood that the isolation structure 600 is made of metal, which has a certain light-shielding or light-blocking effect, which is conducive to achieving privacy display.

[0089] For example, when the isolation structure 600 is reused as the light-shielding structure 500, there is no need to set up an additional light-shielding structure 500.

[0090] In one embodiment, refer to Figures 11 to 14 The shared light-emitting layer 200 and the privacy-protecting light-emitting layer 300 are set in layers.

[0091] It is understandable that the layered arrangement of the shared light-emitting layer 200 and the privacy light-emitting layer 300 should be interpreted broadly. It can be understood that the shared light-emitting layer 200 and the privacy light-emitting layer 300 are not on the same layer. For example, the shared light-emitting layer 200 is located on the side of the privacy light-emitting layer 300 that is away from or close to the substrate 100. It can also be understood that the shared light-emitting layer 200 and the privacy light-emitting layer 300 are prepared through different preparation processes.

[0092] In one embodiment, the display panel further includes: a first pixel defining layer 410 and a second pixel defining layer 420. The first pixel defining layer 410 is located on one side of the substrate 100, and the first pixel defining layer 410 encloses a plurality of shared pixel openings GX, at least a portion of the shared light-emitting device 210 is located in the shared pixel opening GX; the second pixel defining layer 420 is located on the side of the first pixel defining layer 410 away from the substrate 100, and the second pixel defining layer 420 encloses a plurality of privacy pixel openings FK and a plurality of second openings 421, at least a portion of the privacy light-emitting device 310 is located in the privacy pixel opening FK; at least a portion of the orthographic projection of the privacy pixel opening FK on the substrate 100 surrounds the orthographic projection of the corresponding shared pixel opening GX on the substrate 100 (refer to...). Figure 11 ), and / or, at least a portion of the orthographic projection of the shared pixel opening GX on the substrate 100 surrounds the orthographic projection of the corresponding privacy pixel opening FK on the substrate 100 (refer to Figure 12 The orthographic projection of the shared pixel opening GX on the substrate 100 is located within the orthographic projection range of the corresponding second opening 421 on the substrate 100.

[0093] Optionally, the area of ​​the shared pixel opening GX projected onto the substrate 100 is equal to the area of ​​the privacy pixel opening FK projected onto the substrate 100; alternatively, the color of the shared light-emitting device 210 is the same as the color of the corresponding privacy light-emitting device 310.

[0094] Optionally, the second pixel defining layer 420 further encloses a plurality of third openings 422, and the display panel further includes a light-shielding structure 500, at least a portion of which is located within the third openings 422. For example, refer to Figure 11 At least a portion of the orthographic projection of the privacy pixel opening FK on the substrate 100 surrounds the orthographic projection of the corresponding shared pixel opening GX on the substrate 100, and the orthographic projection of the third opening 422 on the substrate 100 is located on the side of the orthographic projection of the privacy pixel opening FK on the substrate 100 that is closer to and farther away from the orthographic projection of the shared pixel opening GX on the substrate 100. For example, refer to... Figure 12 At least a portion of the orthographic projection of the shared pixel opening GX on the substrate 100 surrounds the orthographic projection of the corresponding privacy pixel opening FK on the substrate 100, and the orthographic projection of the third opening 422 on the substrate 100 is located between the orthographic projection of the privacy pixel opening FK on the substrate 100 and the orthographic projection of the shared pixel opening GX on the substrate 100.

[0095] It is understandable that separating the shared light-emitting layer 200 and the privacy light-emitting layer 300 into layers helps reduce the manufacturing difficulty of the shared light-emitting layer 200 and the privacy light-emitting layer 300, and the light-shielding structure 500 has less impact on the light emitted by the shared light-emitting device 210, resulting in a better shared display effect.

[0096] For example, the third electrode 311 is located on the side of the first pixel defining layer 410 facing away from the substrate 100, and at least a portion of the third electrode 311 is exposed to the privacy pixel opening FK; the first electrode 211 is located on the side of the first pixel defining layer 410 close to the substrate 100, and at least a portion of the first electrode 211 is exposed to the shared pixel opening GX. Exemplarily, a third via is provided in the first pixel defining layer 410, a second via in the planarization layer is connected to the third via, and the third electrode 311 is electrically connected to the second transistor 112 through the connected second and third vias; the first electrode 211 is electrically connected to the first transistor 111 through a first via in the planarization layer.

[0097] Optionally, along a direction perpendicular to the plane of the substrate 100, the height of the light-shielding structure 500 is greater than or equal to the thickness of the second pixel defining layer 420. Therefore, the light-shielding structure 500 provides excellent light-shielding effect and excellent privacy display performance.

[0098] For example, the distance from the end of the light-shielding structure 500 away from the substrate 100 to the substrate 100 is greater than or equal to the distance from the surface of the second pixel defining layer 420 away from the substrate 100 to the substrate 100; the distance from the end of the light-shielding structure 500 near the substrate 100 to the substrate 100 is equal to the distance from the surface of the second pixel defining layer 420 near the substrate 100 to the substrate 100.

[0099] Optionally, refer to Figure 13 and Figure 14 The display panel also includes an isolation structure 600 located on the side of the second pixel defining layer 420 opposite to the first pixel defining layer 410. The isolation structure 600 encloses a plurality of first isolation openings 610 and a plurality of second isolation openings 620. The orthographic projection of the shared pixel opening GX on the substrate 100 lies within the orthographic projection range of the corresponding first isolation opening 610 on the substrate 100, and the orthographic projection of the privacy pixel opening FK on the substrate 100 lies within the orthographic projection range of the corresponding second isolation opening 620 on the substrate 100. Therefore, the isolation structure 600 helps improve the manufacturing yield and precision of the shared light-emitting device 210 and the privacy light-emitting device 310, and also reduces the spacing between adjacent light-emitting devices, which helps to further improve the resolution of the display panel.

[0100] For example, refer to Figure 15 and Figure 16 The isolation structure 600 can be reused as the light-shielding structure 500. It can be understood that the material of the isolation structure 600 is metal, which has a certain light-shielding or light-blocking effect, which is conducive to achieving privacy display.

[0101] For example, when the isolation structure 600 is reused as the light-shielding structure 500, there is no need to set up an additional light-shielding structure 500.

[0102] In one embodiment, the display panel further includes: a first pixel defining layer 410 and a second pixel defining layer 420. The first pixel defining layer 410 is located on one side of the substrate 100 and encloses a plurality of privacy pixel openings FK, with at least a portion of the privacy light-emitting device 310 located in the privacy pixel opening FK. The second pixel defining layer 420 is located on the side of the first pixel defining layer 410 away from the substrate 100 and encloses a plurality of shared pixel openings GX and a plurality of second openings 421, with at least a portion of the shared light-emitting device 210 located in the shared pixel opening GX. At least a portion of the orthographic projection of the shared pixel opening GX onto the substrate 100 surrounds the orthographic projection of the corresponding privacy pixel opening FK onto the substrate 100 (see reference). Figure 17 ), and / or, at least a portion of the orthographic projection of the privacy pixel opening FK onto the substrate 100 surrounds the orthographic projection of the corresponding shared pixel opening GX onto the substrate 100 (refer to Figure 18 The orthographic projection of the privacy pixel opening FK on the substrate 100 is located within the orthographic projection range of the corresponding second opening 421 on the substrate 100.

[0103] Optionally, the first pixel defining layer 410 further encloses a plurality of first openings 411, and the display panel further includes a light-shielding structure 500, at least a portion of which is located within the first openings 411. For example, see reference to Figure 17 At least a portion of the orthographic projection of the shared pixel opening GX on the substrate 100 surrounds the orthographic projection of the corresponding privacy pixel opening FK on the substrate 100, and the orthographic projection of the first opening 411 on the substrate 100 lies between the orthographic projection of the privacy pixel opening FK on the substrate 100 and the orthographic projection of the shared pixel opening GX on the substrate 100. For example, referring to... Figure 18 At least a portion of the orthographic projection of the privacy pixel opening FK on the substrate 100 surrounds the orthographic projection of the corresponding shared pixel opening GX on the substrate 100. The orthographic projection of the first opening 411 on the substrate 100 is located on the side of the orthographic projection of the privacy pixel opening FK on the substrate 100 that is closer to and farther away from the orthographic projection of the shared pixel opening GX on the substrate 100. Therefore, the light-shielding structure 500 has almost no effect on the light emitted by the shared light-emitting device 210, and the light emitted by the privacy light-emitting device 310 can be effectively blocked by the light-shielding structure 500, resulting in a better privacy protection effect.

[0104] It is understandable that separating the shared light-emitting layer 200 and the privacy light-emitting layer 300 into layers helps reduce the manufacturing difficulty of the shared light-emitting layer 200 and the privacy light-emitting layer 300, and the light-shielding structure 500 has less impact on the light emitted by the shared light-emitting device 210, resulting in a better shared display effect.

[0105] For example, the height of the light-shielding structure 500 is greater than the thickness of the first pixel defining layer 410 and less than the sum of the thickness of the first pixel defining layer 410 and the thickness of the second pixel defining layer 420.

[0106] For example, the distance from the end of the light-shielding structure 500 away from the substrate 100 to the substrate 100 is less than the distance from the surface of the second pixel defining layer 420 away from the substrate 100 to the substrate 100, and greater than the distance from the surface of the first pixel defining layer 410 away from the substrate 100 to the substrate 100; the distance from the end of the light-shielding structure 500 near the substrate 100 to the substrate 100 is equal to the distance from the surface of the first pixel defining layer 410 near the substrate 100 to the substrate 100.

[0107] Optionally, the second pixel defining layer 420 covers the light-shielding structure 500.

[0108] For example, the material of the first pixel defining layer 410 can be yellow organic adhesive, and the material of the second pixel defining layer can also be yellow organic adhesive.

[0109] In another embodiment, refer to Figure 19 and Figure 20 The first pixel defining layer 410 is black. In this embodiment, there is no need to set up a light-shielding structure 500. The first pixel defining layer 410 can play the role of blocking light, thereby achieving a privacy protection effect; it can also reduce the manufacturing difficulty of the display panel and simplify the manufacturing process.

[0110] It is understood that when the color of the first pixel defining layer 410 is black, the shared light-emitting layer 200 and the privacy light-emitting layer 300 are layered, and the shared light-emitting layer 200 is located on the side of the privacy light-emitting layer 300 away from the substrate 100. The first pixel defining layer 410 encloses the privacy pixel opening FK, and at least a portion of the privacy light-emitting device 310 is located in the privacy pixel opening FK. The second pixel defining layer 420 encloses the shared pixel opening GX, and at least a portion of the shared light-emitting device 210 is located in the shared pixel opening GX.

[0111] For example, the first electrode 211 is located on the side of the first pixel defining layer 410 facing away from the substrate 100, and at least a portion of the first electrode 211 is exposed to the shared pixel opening GX; the third electrode 311 is located on the side of the first pixel defining layer 410 close to the substrate 100, and at least a portion of the third electrode 311 is exposed to the privacy pixel opening FK. Exemplarily, a fourth via is provided in the first pixel defining layer 410, and a first via in the planarization layer is connected to the fourth via. The first electrode 211 is electrically connected to the first transistor 111 through the connected fourth via and the first via; the third electrode 311 is electrically connected to the second transistor 112 through a second via in the planarization layer.

[0112] Optionally, the area of ​​the shared pixel opening GX projected onto the substrate 100 is equal to the area of ​​the privacy pixel opening FK projected onto the substrate 100. Optionally, the color of the shared light-emitting device 210 is the same as the color of the corresponding privacy light-emitting device 310. Therefore, when switching between the lighting states of the shared light-emitting device 210 and the privacy light-emitting device 310, the brightness and resolution perceived by the user at the same screen position remain almost unchanged, resulting in a consistent and uniform visual experience. If the color of the shared light-emitting device 210 is different from the color of the corresponding privacy light-emitting device 310, when switching between the lighting states of the shared light-emitting device 210 and the privacy light-emitting device 310, the displayed image perceived by the user at the same screen position will exhibit greater abruptness, resulting in a relatively poor visual experience.

[0113] In a preferred embodiment, the shared light-emitting layer 200 is located on the side of the privacy light-emitting layer 300 facing away from the substrate 100. Therefore, the privacy light-emitting layer 300 has almost no effect on the shared light-emitting layer 200, resulting in better display performance in shared display mode and better privacy protection in privacy display mode.

[0114] Optionally, refer to Figures 21 to 24 The display panel also includes an isolation structure 600 located on the side of the second pixel defining layer 420 opposite to the first pixel defining layer 410. The isolation structure 600 encloses a plurality of first isolation openings 610 and a plurality of second isolation openings 620. The orthographic projection of the shared pixel opening GX on the substrate 100 lies within the orthographic projection range of the corresponding first isolation opening 610 on the substrate 100, and the orthographic projection of the privacy pixel opening FK on the substrate 100 lies within the orthographic projection range of the corresponding second isolation opening 620 on the substrate 100. The isolation structure 600 helps improve the manufacturing precision and yield of the shared light-emitting device 210 and the privacy light-emitting device 310, and is more conducive to obtaining a display panel with better performance.

[0115] Exemplarily, the isolation structure 600 includes an isolation portion 602 and a blocking portion 601 stacked along a direction away from the substrate 100, wherein the width of the blocking portion 601 is greater than the width of the isolation portion 602. Thus, the two ends of the blocking portion 601 protrude compared to the sides of the isolation portion 602, and this shape of the isolation structure 600 is also referred to as a hanging shape. The isolation portion 602 and the blocking portion 601 are made of different materials, and the etching rate of the blocking portion 601 is lower than the etching rate of the isolation portion 602. The material of the isolation portion 602 includes a conductive material, specifically including at least one of aluminum (Al), aluminum alloys, and aluminum alloys including at least one of aluminum-neodymium alloy (AlNd), aluminum-yttrium alloy (AlY), or aluminum-silicon alloy (AlSi). The blocking portion 601 can be a single-layer structure or a multi-layer structure. When the blocking portion 601 is a single-layer structure, the material of the blocking portion 601 can include at least one of titanium, titanium nitride, molybdenum, tungsten, molybdenum-tungsten alloy, or molybdenum-niobium alloy. When the blocking part 601 has a multi-layer structure, one layer of the blocking part 601 is made of at least one of titanium, titanium nitride, molybdenum, tungsten, molybdenum-tungsten alloy or molybdenum-niobium alloy, and the other layer of the blocking part 601 may be made of conductive oxide or inorganic insulating material, such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0116] In some embodiments, the isolation structure 600 may further include a base 603 located on the side of the isolation portion 602 near the substrate 100. The base 603 protrudes relative to the isolation portion 602 in the direction toward the isolation opening 610, and the orthographic projection of the isolation portion 602 on the substrate 100 lies within the orthographic projection of the base 603 on the substrate 100. The material of the base 603 may include at least one of molybdenum (Mo), titanium (Ti), titanium nitride (TiN), molybdenum-tungsten alloy (MoW), or molybdenum-niobium alloy (MoNb).

[0117] It is understandable that the structure and manufacturing method of the isolation structure 600 can be referred to the relevant contents recorded in CN118251982A, CN115666161A, CN116648095A, CN117062489A, CN118678742A, CN118785761A, CN115224220A, CN118678729A, CN118660529A, and CN118660589A, and will not be elaborated further here.

[0118] For example, refer to Figure 25 and Figure 26 The isolation structure 600 can be reused as the light-shielding structure 500. It can be understood that the material of the isolation structure 600 is metal, which has a certain light-shielding or light-blocking effect, which is conducive to achieving privacy display.

[0119] For example, when the isolation structure 600 is reused as the light-shielding structure 500, there is no need to set up an additional light-shielding structure 500.

[0120] Optionally, the orthographic projection of the light-shielding structure 500 on the substrate 100 is located within the orthographic projection range of the isolation structure 600 on the substrate 100.

[0121] For example, the display panel also includes a packaging layer, a touch structure, and other structures, which will not be described in detail here.

[0122] It is understood that the display panel of this embodiment can achieve dynamic privacy protection without changing the resolution.

[0123] A second aspect of this disclosure provides a display panel, which includes a substrate 100, a shared light-emitting layer 200, and a privacy light-emitting layer 300.
