DETAILED DESCRIPTION

[0081] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0082] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0083] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0084] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0085] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0086] See also Figure 1 The inventors have found that in some existing display panels, light-emitting devices of different colors are usually arranged in the same layer. For example, such a display panel usually includes an array substrate 910', a pixel defining layer 930' located on one side of the array substrate 910', and a light-emitting device located in a pixel opening of the pixel defining layer 930'. Among them, light-emitting devices of different colors are arranged in the same layer, for example, the anode 920' in the red light-emitting device R, the green light-emitting device G, and the blue light-emitting device B are all arranged in the same layer, the light-emitting material layer 950' in the red light-emitting device R, the green light-emitting device G, and the blue light-emitting device B are all arranged in the same layer, and the cathode 960' in the red light-emitting device R, the green light-emitting device G, and the blue light-emitting device B are all arranged in the same layer.

[0087] Therefore, this type of display panel has the problem that the pixels occupy a large area and the pixel density is difficult to further increase.

[0088] In view of this, this embodiment provides a solution that can further improve the pixel density. The solution provided by this embodiment is described in detail below.

[0089] See also Figure 2 , Figure 2 This is a schematic diagram of a display panel provided in this embodiment. The display panel may include a first device layer and a second device layer that are stacked.

[0090] The first device layer includes a first array functional layer 110 and a first light emitting functional layer 120 which are stacked.

[0091] The second device layer includes a second array functional layer 210 and a second light emitting functional layer 220 which are stacked.

[0092] The first array functional layer 110 , the first light-emitting functional layer 120 , the second array functional layer 210 , and the second light-emitting functional layer 220 are stacked in sequence.

[0093] The first light-emitting functional layer 120 can be manufactured based on the first array functional layer 110 , and the second light-emitting functional layer 220 can be manufactured based on the second array functional layer 210 .

[0094] Optionally, the display panel provided in this embodiment may further include a first transparent adhesive layer 801 located between the first light-emitting functional layer 120 and the second array functional layer 2110, that is, the first light-emitting functional layer 120 and the second array functional layer 210 may be bonded by the first transparent adhesive layer 801. The material of the second transparent adhesive layer 802 may include an optically transparent resin.

[0095] The first array functional layer 110 includes a first driving device region. In this embodiment, the first array functional layer 110 may include a plurality of film layer structures, such as a substrate, a buffer layer, an active layer, a plurality of metal layers, a plurality of insulating layers, and a planarization layer, etc. The plurality of film layer structures may form a plurality of thin film transistors (TFTs) at different positions of the first array functional layer 110, and the thin film transistors cooperate with each other to form a plurality of first pixel driving circuits.

[0096] The first light-emitting functional layer 120 includes a plurality of first light-emitting devices 121 arranged at intervals. For example, the first light-emitting functional layer 120 may include a first pixel defining layer 122 located on one side of the first array functional layer 110, the first pixel defining layer 122 includes a plurality of first pixel openings arranged at intervals, and the first light-emitting devices 121 are at least partially located in the first pixel openings.

[0097] Optionally, the first light-emitting device 121 includes a first electrode 1211, a first light-emitting material layer 1212, and a second electrode 1213 stacked in a direction away from the first array functional layer 110. The second electrode 1213 may be made of a transparent conductive material, such as silver that can transmit light. The first electrode 1211 is made of an opaque conductive material. The first array functional layer 110 may not have a light-transmitting area, or may have a light-transmitting area, which is not specifically limited in this embodiment.

[0098] The second array functional layer 210 includes a second driving device area 211 and a first light-transmitting area 212. The second array functional layer 210 may include a plurality of film layer structures, such as a substrate, a buffer layer, an active layer, a plurality of metal layers, a plurality of insulating layers, and a planarization layer, etc. The plurality of film layer structures may form a plurality of thin film transistors (TFTs) at different positions of the second array functional layer 210, and the thin film transistors cooperate with each other to form a plurality of second pixel driving circuits.

[0099] Optionally, see Figure 3 In the second array functional layer 210, the entire film layer (such as the substrate, the buffer layer, the insulating layer, and the planarization layer) can be made of a transparent material, and the wiring or electrodes (such as semiconductor wiring, metal wiring, and metal electrodes) forming the second pixel driving circuit can avoid certain areas, thereby forming a light-transmitting first light-transmitting area 212 on the second array functional layer 210.

[0100] The second light-emitting functional layer 220 includes a plurality of second light-emitting devices 221 arranged at intervals. For example, the second light-emitting functional layer 220 may include a second pixel defining layer 222 located on one side of the second array functional layer 210, the second pixel defining layer 222 includes a plurality of second pixel openings arranged at intervals, and the second light-emitting devices 221 are at least partially located in the second pixel openings.

[0101] The second light-emitting device 221 has light transmittance. For example, the second light-emitting device 221 includes a third electrode 2211, a second light-emitting material layer 2212, and a fourth electrode 2213 stacked in a direction away from the second array functional layer 210, wherein the third electrode 2211 and the fourth electrode 2213 can be made of a transparent conductive material, such as the third electrode 2211 can be made of indium tin oxide (ITO), and the fourth electrode 2213 can be made of silver that can transmit light.

[0102] In this embodiment, the orthographic projections of the first light-transmitting area 212 and the second light-emitting device 221 on the first light-emitting functional layer 120 at least partially overlap with the first light-emitting device 121. In this way, the light emitted by the first light-emitting device 121 can be emitted through the first light-transmitting area 212 of the second array functional layer 210 and the first light-emitting device 121.

[0103] Based on the above design, in this embodiment, by setting the second light-emitting device 221 in the second array functional layer 210 to be light-transmissive and providing the first light-transmissive region 212 in the second array functional layer 210, the second light-emitting functional layer 220 can be stacked with the first light-emitting functional layer 120. In this way, the area occupied by the light-emitting device can be reduced and the pixel density of the display panel can be improved.

[0104] In some possible implementations, the display panel may have only two light-emitting functional layers (ie, the first light-emitting functional layer 120 and the second light-emitting functional layer 220 ).

[0105] In this case, at least some of the first light emitting devices 121 emit the same light color, at least some of the second light emitting devices 221 emit the same light color, and the first light emitting devices 121 and the second light emitting devices 221 emit different light colors.

[0106] For example, the light emitting colors of the first light emitting device 121 may all be the first color, the light emitting colors of the second light emitting device 221 may include the second color and the third color, and the first color, the second color and the third color are different from each other; or the light emitting colors of the first light emitting device 121 may include the first color and the second color, the light emitting colors of the second light emitting device 221 may all be the third color, and the first color, the second color and the third color are different from each other. The first color, the second color and the third color may be one of red, green and blue, respectively.

[0107] It should be noted that the above example is only a possible implementation of this embodiment. In this embodiment, the light-emitting device may also include light-emitting devices with more colors, such as red, green, blue and white.

[0108] In some other possible implementations, the display panel may have more device layers.

[0109] Optionally, the display panel provided in this embodiment may further include a second transparent adhesive layer 802 located between the second light-emitting functional layer 220 and the third array functional layer 310 .

[0110] The third light emitting functional layer 320 can be manufactured based on the third array functional layer 310 , and then the second light emitting functional layer 220 and the third array functional layer 310 are bonded together through the second transparent adhesive layer 802 .

[0111] Optionally, the material of the second transparent adhesive layer 802 may include optical clear resin.

[0112] The third array functional layer 310 includes a third driving device area 311 and a second light-transmitting area 312. The third array functional layer 310 may include a plurality of film layer structures, such as a substrate, a buffer layer, an active layer, a plurality of metal layers, a plurality of insulating layers, and a planarization layer. The plurality of film layer structures may form a plurality of thin film transistors (TFTs) at different positions of the third array functional layer 310, and the thin film transistors cooperate with each other to form a plurality of third pixel driving circuits.

[0113] Optionally, see Figure 5In the third array functional layer 310, the entire film layer (such as the substrate, the buffer layer, the insulating layer, and the planarization layer) can be made of a transparent material, and the wiring or electrodes (such as semiconductor wiring, metal wiring, and metal electrodes) forming the third pixel driving circuit can avoid certain areas, thereby forming a second light-transmitting area 312 on the third array functional layer 310.

[0114] The third light-emitting functional layer 320 includes a plurality of third light-emitting devices 321 arranged at intervals. For example, the third light-emitting functional layer 320 may include a third pixel defining layer 322 located on one side of the third array functional layer 310, the third pixel defining layer 322 includes a plurality of third pixel openings arranged at intervals, and the third light-emitting device 321 is at least partially located in the third pixel opening.

[0115] The third light-emitting device 321 has light transmittance. For example, the third light-emitting device 321 includes a fifth electrode 3211, a third light-emitting material layer 3212, and a sixth electrode 3213 stacked in a direction away from the third array functional layer 310, wherein the fifth electrode 3211 and the sixth electrode 3213 can be made of a transparent conductive material, such as the fifth electrode 3211 and can be made of indium tin oxide (ITO), and the sixth electrode 3213 can be made of silver that can transmit light.

[0116] In this embodiment, the orthographic projections of the first light-transmitting area 212, the second light-emitting device 221, the second light-transmitting area 312, and the third light-emitting device 321 on the first light-emitting functional layer 120 at least partially overlap with the first light-emitting device 121. In this way, the light emitted by the first light-emitting device 121 can be emitted through the first light-transmitting area 212, the second light-emitting device 221, the second light-transmitting area 312, and the third light-emitting device 321 of the second array functional layer 210, and the light emitted by the second light-emitting device 221 can be emitted through the second light-transmitting area 312 and the third light-emitting device 321 of the third array functional layer 310.

[0117] In some possible implementations, the orthographic projections of the third driving device area 311 and the second driving device area 211 on the first array functional layer 110 at least partially overlap. In this way, the overlapping area of ​​the second light-transmitting area 312 and the first light-transmitting area 212 can be increased as much as possible to ensure the light extraction effect.

[0118] In this case, optionally, the light-emitting colors of the first light-emitting devices 121 are the same, the light-emitting colors of the second light-emitting devices 221 are the same, the light-emitting colors of the third light-emitting devices 321 are the same, and the light-emitting colors of the first light-emitting devices 121, the second light-emitting devices 221, and the third light-emitting devices 321 are different from each other. For example, the first color, the second color, and the third color can be one of red, green, and blue, respectively.

[0119] It should be noted that the above example is only a possible implementation of this embodiment. In this embodiment, the light emitting device may also include more light emitting colors, such as red, green, blue and white. The first light emitting device 121, the second light emitting device 221 and / or the third light emitting device 321 may also have two or more light emitting colors.

[0120] In some possible implementations, the orthographic projections of the light emitting centers of the first light emitting device 121 and the second light emitting device 221 on the first array functional layer 110 coincide. For example, the orthographic projections of the first light emitting device 121 and the second light emitting device 221 on the first array functional layer 110 are located within the orthographic projection of the first light-transmitting area 212 on the first array functional layer 110.

[0121] In the case where the display panel provided in this embodiment has three light-emitting functional layers, the orthographic projections of the light-emitting centers of the first light-emitting device 121, the second light-emitting device 221, and the third light-emitting device 321 on the first array functional layer 110 coincide. For example, the orthographic projections of the first light-emitting device 121, the second light-emitting device 221, and the third light-emitting device 321 on the first array functional layer 110 are located within the orthographic projections of the first light-transmitting area 212 and the second light-transmitting area 312 on the first array functional layer 110.

[0122] In this way, the obstruction of each array functional layer to the light emitting path of the light emitting device can be reduced, thereby ensuring the light extraction efficiency.

[0123] For some possible implementations, see again Figure 2 , the first light-emitting functional layer 120 further includes a first encapsulation layer 124 located on the side of the second electrode 1213 away from the first array functional layer 110, and the second light-emitting functional layer 220 further includes a second encapsulation layer 224 located on the side of the fourth electrode 2213 away from the first array functional layer 110.

[0124] Optionally, see again Figure 4 In the case where the display panel further includes a third array functional layer 310 and a third light-emitting functional layer 320, the third light-emitting functional layer 320 further includes a third encapsulation layer 324 located on a side of the sixth electrode 3213 away from the first array functional layer 110. In this case, the second transparent adhesive layer 802 may be located between the second encapsulation layer 224 and the third array functional layer 310, and adhere the second encapsulation layer 224 and the third array functional layer 310.

[0125] Optionally, in the above implementation, the first encapsulation layer 124, the second encapsulation layer 224 and / or the third encapsulation layer 324 may be a single-layer structure. For example, the first encapsulation layer 124, the second encapsulation layer 224 and / or the third encapsulation layer 324 may be a single-layer structure and may be an inorganic encapsulation layer formed by chemical vapor deposition (CVD).

[0126] Alternatively, the first encapsulation layer 124, the second encapsulation layer 224 and / or the third encapsulation layer 324 may also be a multi-layer structure. For example, the first encapsulation layer 124, the second encapsulation layer 224 and / or the third encapsulation layer 324 may respectively be an inorganic-organic-inorganic three-layer material composite structure.
