DETAILED DESCRIPTION

[0051] 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.

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.

[0055] 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.

[0056] See also Figure 1 , Figure 1This is a schematic diagram of a display panel provided in this embodiment. The display panel may include an array substrate 110 , a first electrode layer 120 , a partition structure 130 , a light-emitting layer 150 , a second electrode layer 160 , a first encapsulation layer 170 and a filter layer 180 .

[0057] The array substrate 110 may be formed based on a hard substrate, such as a sapphire substrate; or, the array substrate 110 may also be formed based on a flexible substrate, such as a substrate based on a polyimide (Pi) material.

[0058] The array substrate 110 may include a plurality of drive units, each of which may include one or more semiconductor switch devices. The semiconductor switch device may be formed by the cooperation of a plurality of film layers in the array substrate 110, for example, the semiconductor switch device may be a thin film transistor (TFT) formed by the cooperation of a plurality of film layers.

[0059] The first electrode layer 120 is located on one side of the array substrate 110. The first electrode layer 120 includes a plurality of first electrodes arranged at intervals. The plurality of first electrodes can be electrically connected to a plurality of driving units respectively, and the driving units can provide driving voltages for the first electrodes.

[0060] The partition structure 130 is located on a side of the first electrode layer 120 away from the array substrate 110 , and includes a pixel opening exposing the first electrode. Adjacent first electrodes are isolated from each other by the partition structure 130 .

[0061] The light emitting layer 150 , the second electrode layer 160 and the first packaging layer 170 are stacked in sequence from the direction close to the array substrate 110 to the direction away from the array substrate 110 , and at least part of the light emitting layer 150 , the second electrode layer 160 and the first packaging layer 170 are located in the pixel opening.

[0062] When forming the light emitting layer 150 and the second electrode layer 160 , the partition structure 130 can disconnect the light emitting layer 150 and the second electrode layer 160 of adjacent sub-pixels, thereby patterning the light emitting layer 150 and the second electrode layer 160 without using a precision mask.

[0063] The filter layer 180 is located on a side of the first encapsulation layer 170 and the partition structure 130 away from the array substrate 110. The orthographic projection of the partition structure 130 on the array substrate 110 is located within the orthographic projection of the filter layer 180 on the array substrate 110. In this embodiment, the filter layer 180 can be provided as a whole layer, that is, the filter layer 180 can cover the partition structure 130 and the first encapsulation layer 170.

[0064] In this embodiment, the filter layer 180 can only allow light of a certain color to pass through and block light of other colors. In this way, by providing the filter layer 180 that can cover the partition structure 130, the filter layer 180 blocks the light from the outside that irradiates the partition structure 130, thereby reducing the reflective effect of the partition structure 130 or other film layers on the partition structure 130, thereby improving the user's visual experience.

[0065] In a possible implementation, the filter layer 180 includes at least two filter regions of different colors, two adjacent filter regions of different colors are in contact with each other, and the orthographic projection of the boundary position on the array substrate 110 is located between adjacent pixel openings.

[0066] Preferably, the orthographic projection of a pixel opening on the array substrate 110 is located within the orthographic projection of a filter region on the array substrate 110. That is, a filter region of one color can cover a pixel opening corresponding to a sub-pixel of one color.

[0067] For example, please refer again to Figure 1 , Figure 1 Two sub-pixels in the display panel provided by this embodiment are shown, and the two sub-pixels may be a red sub-pixel and a blue sub-pixel, wherein the filter layer 180 may include a filter region 180R covering the pixel opening of the red sub-pixel and a filter region 180B covering the pixel opening of the blue sub-pixel. Furthermore, the filter region 180R and the filter region 180B may be in direct contact, and the boundary position is located between the pixel openings corresponding to the red sub-pixel and the blue sub-pixel.

[0068] Based on the above design, in this embodiment, by setting the partition structure 130 to separate adjacent sub-pixels, the light mixing between adjacent pixels can be reduced. In this case, the filter layer 180 can be directly used to cover the partition structure 130 between the pixel openings, and there is no need to additionally set a black matrix layer corresponding to the pixel gap position. In this way, compared with the solution in the prior art that still needs to set a black matrix layer, the solution provided in this embodiment can reduce the manufacturing process and reduce the manufacturing cost of the display panel.

[0069] In a possible implementation, the display panel further includes a second encapsulation layer 190 located on a side of the filter layer 180 away from the array substrate 110 .

[0070] Preferably, the material of the first encapsulation layer 170 includes an inorganic material, and the material of the second encapsulation layer 190 includes an organic material.

[0071] Specifically, in this embodiment, in the process of forming the patterned light-emitting layer 150 and the second electrode layer 160 based on the partition structure 130, the first encapsulation layer 170 covering the second electrode layer 160 has been formed. In this case, after forming the light-emitting layer 150, the second electrode layer 160 and the first encapsulation layer 170 of each color sub-pixel, the filter layer 180 can be provided first, and then the second encapsulation layer 190 can be provided.

[0072] In this way, compared with the existing solution of setting the filter on the organic encapsulation layer by using the Color Filter on Encap (COE) technology, the solution provided in this embodiment can set the filter layer 180 under the second encapsulation layer 190, thereby reducing the distance between the filter layer 180 and the partition structure 130, avoiding the light from being transmitted from the side to between the filter layer 180 and the partition structure 130, so that the filter layer 180 can better block the partition structure 130 and reduce the reflective effect of the partition structure 130.

[0073] In one possible implementation, please refer again to Figure 1 The partition structure 130 may include a pixel defining layer 131 and a partition portion 132 located on a side of the pixel defining layer 131 away from the array substrate 110. The orthographic projection of the partition portion 132 on the array substrate 110 is located within the orthographic projection of the pixel defining layer 131 on the array substrate 110.

[0074] The partition portion 132 may be conductive, and at least part of the second electrode layer 160 extends from the pixel opening to the side of the pixel defining layer 131 away from the array substrate 110 and is in electrical contact with the partition portion 132. The orthographic projection of the light emitting layer 150 on the array substrate 110 is located within the orthographic projection of the second electrode layer 160 on the array substrate 110. The partition portion 132 may form a connection structure or wiring to connect the second electrode layer 160 in adjacent pixel openings or to connect the second electrode layer 160 to other circuits. In this way, the manufacturing difficulty of the display panel can be reduced.

[0075] Further, in a possible implementation, please refer to Figure 2 , Figure 2 This is a top perspective view of the display panel provided in this embodiment. The display panel provided in this embodiment may also include a connecting line 140 arranged on the same layer as the partition part 132, and the connecting line 140 is located between adjacent partition parts 132, and at least part of the connecting line 140 is electrically connected to at least part of the partition part 132.

[0076] For example, see Figure 3 , Figure 3 for Figure 2As shown in the cross-sectional view along the AA direction, the partition portion 132 and the connecting trace 140 can be formed by etching the same film layer.

[0077] The display panel provided in this embodiment may include a first operating mode and a second operating mode.

[0078] In the first working mode, the connecting wire 140 and the partition 132 are used to transmit a driving signal to the second electrode layer 160 to drive the light-emitting layer 150 to emit light. For example, the connecting wire 140 and the partition 132 connect the second electrode layer 160 to the driving circuit, so that the second electrode layer 160 and the first electrode layer 120 cooperate to drive the light-emitting layer 150 to emit light.

[0079] In the second working mode, the connection trace 140, the partition portion 132 and the second electrode layer 160 are used together as touch electrodes for transmitting touch signals. For example, the connection trace 140 and the partition portion 132 connect the second electrode layer 160 to the touch detection circuit.

[0080] Optionally, the connecting traces 140 and the partitioning portion 132 connect the second electrode layer 160 to a multiplexing control circuit.

[0081] The multiplexing control circuit is used to control the second electrode layer 160 electrically connected to the partition part 141 to cooperate with the first electrode to drive the light-emitting layer 150 to emit light in the first working mode. The multiplexing control circuit is also used to receive the touch sensing signal sensed by the second electrode layer 160 through the partition part 132 and / or transmit the touch detection signal to the second electrode layer 160 in the second working mode.

[0082] That is, in the first working mode, the second electrode layer 160 and the first electrode cooperate with each other as driving electrodes to drive the light-emitting layer 150 to emit light; in the second working mode, the second electrode layer 160 can be reused as a touch electrode together with the partition part 132 to realize touch detection.

[0083] Based on the above design, in the solution provided by this embodiment, since the partition part 132 is provided to disconnect the light emitting layer 150 and the second electrode layer 160 of adjacent sub-pixels, the second electrode layer 160 of each sub-pixel can be controlled separately, so that the partition part 132 and the second electrode layer 160 can be reused as a touch electrode. In this way, the number of film layers of the display panel can be reduced, and the overall lightness and thinness of the display panel can be improved.

[0084] For further information, please refer to Figure 2 or Figure 4 In one example, one partition portion 132 or a plurality of adjacent and electrically connected partition portions 132 form a touch electrode block, and the connecting traces 140 connect the touch electrodes to one side of the display panel.

[0085] In this way, the connection trace 140 connecting one partition portion 132 or a plurality of adjacent and electrically connected partition portions 141 can form a touch electrode layout in a self-capacitive form.

[0086] Please refer to Figure 5 In another example, one partition portion 132 or multiple adjacent and electrically connected partition portions 132 form a touch electrode block, and the connecting trace 140 includes a first connecting trace 141 extending along the first direction D1 and a second connecting trace 142 extending along the second direction D2.

[0087] The first connection line 141 connects a plurality of touch electrode blocks arranged along the first direction D1 into a first touch electrode strip, and the second connection line 142 connects a plurality of touch electrode blocks arranged along the second direction D2 into a second touch electrode strip.

[0088] In this way, the first connecting line 141 can connect multiple partition parts 132 to form a first touch electrode strip extending along the first direction D1, and the second connecting line 142 can connect multiple partition parts 132 to form a second touch electrode strip extending along the second direction D2. The first touch electrode strip and the second touch electrode strip can cooperate to form a touch electrode layout in the form of mutual capacitance.

[0089] Optionally, in Figure 5 On the basis of the shown scheme, the array substrate 110 or the first electrode layer 120 includes a touch bridge line 143, the second connecting line 142 includes at least one breakpoint, the breakpoints of the second connecting line 142 are interconnected through the touch bridge line 143, and the orthographic projection of the touch bridge line 143 on the array substrate 110 at least partially overlaps with the orthographic projection of the first connecting line 1421 on the array substrate 110. For example, the orthographic projection of the touch bridge line 143 on the array substrate 110 intersects with the orthographic projection of the first connecting line 1421 on the array substrate 110.

[0090] That is, the second connection line 142 is disconnected at a position where it may intersect with the first connection line 14, and the disconnected portion can be connected to each other through the touch bridge line 143. In this way, the first connection line 1421 extending along the first direction D1 and the second connection line 1422 extending along the second direction D2 can be prevented from being crossed and shorted.

[0091] Optionally, see Figure 6 The touch bridge line 143 may be located in the first electrode layer, and the second wiring 142 is electrically connected to the third wiring 143 through a through hole penetrating the pixel defining layer 131 .

[0092] In another possible implementation, see Figure 7The partition structure 130 may include a pixel defining layer 131 and a partition portion 132 located on a side of the pixel defining layer 131 away from the array substrate 110. The orthographic projection of the partition portion 132 on the array substrate 110 is located within the orthographic projection of the pixel defining layer 131 on the array substrate 110.

[0093] The display panel further includes a touch layer 220 located on a side of the partition portion 132 away from the array substrate 110, and the orthographic projection of the touch layer 220 on the array substrate 110 is located within the orthographic projection of the partition portion 132 on the array substrate 110. In addition, the filter layer 210 is located on a side of the touch layer 220 away from the array substrate 110.

[0094] Specifically, an insulating layer may be provided on a side of the partition portion 132 away from the array substrate 110 , and the conductive trace structure included in the touch layer 220 may be provided on a side of the insulating layer away from the array substrate 110 .

[0095] In this way, by providing the filter layer 180 that can cover the touch layer 220 , the filter layer 180 blocks the light from the outside irradiating the touch layer 220 , thereby reducing the reflection effect of the touch layer 220 and improving the user's visual experience.

[0096] In a possible implementation, a side of the partition portion 132 close to the pixel opening may form an undercut structure, so as to better disconnect the light emitting layer 150 and the second electrode layer 160.

[0097] For example, see Figure 8 The partition portion 132 may be composed of a first metal layer 1321, a second metal layer 1322, and a third metal layer 1323 which are stacked in sequence from a direction close to the array substrate 110 to a direction away from the array substrate 110. The first metal layer 1321 and the second metal layer 1322 may be retracted relative to the first metal layer 1323, that is, the orthographic projections of the first metal layer 1321 and the second metal layer 1322 on the array substrate 110 are located within the orthographic projection of the third metal layer 1323 on the array substrate 110.

[0098] Furthermore, the corrosion resistance of the first metal layer 1321 and the second metal layer 1322 may be weaker than that of the third metal layer 1323. In this way, the first metal layer 1321 and the second metal layer 1322 may be retracted relative to the third metal layer 1323 by side engraving to form the above-mentioned undercut structure. For example, the material of the first metal layer 1321 may include molybdenum (Mo), the material of the second metal layer 1322 may include aluminum (Al), and the material of the third metal layer 1323 may include titanium (Ti).

[0099] It should be noted that in other implementations, the partition portion 132 may also be composed of film layers of other materials, or may form an undercut structure by other methods, which is not specifically limited in this embodiment.

[0100] Please refer to Fig. 9 This embodiment also provides a method for manufacturing a display panel. The method can be used to manufacture the above-mentioned display panel provided in this embodiment. The method may include the following steps.

[0101] Step S110 , providing an array substrate 110 .

[0102] Step S120 , forming a first electrode layer 120 on one side of the array substrate 110 , wherein the first electrode layer 120 includes a plurality of first electrodes disposed at intervals.

[0103] In step S130 , a partition structure 130 is formed on one side of the array substrate 110 . The partition structure 130 includes a pixel opening exposing the first electrode layer 120 .

[0104] In step S140 , a light emitting layer 150 , a second electrode layer 160 , and a first encapsulation layer 170 are stacked in the pixel opening.

[0105] Step S150 , forming a filter layer 180 on the first packaging layer 170 and the partition structure 130 away from the array substrate 110 . The orthographic projection of the partition structure 130 on the array substrate 110 is located within the orthographic projection of the filter layer 180 on the array substrate 110 .

[0106] For details, please refer to Figures 7 to 10 Through step S110 and step S120, a plurality of first electrodes spaced apart from each other can be formed on the entire column of substrates.

[0107] Step S130 may include the following sub-steps.

[0108] Step S131 , forming a pixel defining layer 131 covering the first electrode.

[0109] Step S132, at least two metal layers are formed on the side of the pixel defining layer 131 away from the array substrate 110, wherein the corrosion resistance of at least one metal layer close to the array substrate 110 is weaker than the corrosion resistance of at least one metal layer away from the array substrate 110. Then, the at least two metal layers are patterned to etch away the metal layer covering the first electrode. Then, the at least two metal layers are side-etched. Since the corrosion resistance of at least one metal layer close to the array substrate 110 is weaker, an undercut structure can be formed at the edges of the at least two metal layers, thereby forming a partition portion 132.

[0110] In step S133 , the pixel defining layer 131 is patterned to form a pixel opening on the pixel defining layer 131 to expose the first electrode.

[0111] Step S140 may include the following sub-steps.

[0112] In step S141 , a light-emitting layer 150 - 1 corresponding to the first color, a second electrode layer 160 - 1 corresponding to the first color, and a first encapsulation layer 170 - 1 corresponding to the first color are sequentially formed to cover the entire surface.

[0113] In this step, since the partition portion 132 has a bottom cut structure, when the light-emitting layer 150-1 and the second electrode layer 160-1 are formed by evaporation, the light-emitting layer 150-1 and the second electrode layer 160-1 located on the side of the partition portion 132 away from the array substrate 110 and the light-emitting layer 150-1 and the second electrode layer 160-1 located at the pixel opening will be disconnected.

[0114] Meanwhile, by controlling the evaporation angle, the light emitting layer 150 - 1 may not contact the partition portion 132 , but the second electrode layer 160 - 1 may extend from the pixel opening to be in electrical contact with the partition portion 132 .

[0115] Step S142 , forming an etching protection layer 210 - 1 covering the pixel opening of the first color sub-pixel.

[0116] Step S143 , removing the first encapsulation layer 170 - 1 , the light emitting layer 150 - 1 , and the second electrode layer 160 - 1 that are not covered by the etching protection layer 210 - 1 .

[0117] Step S144, removing the etching protection layer 210-1.

[0118] Thus, the light emitting layer 150 - 1 and the second electrode layer 160 - 1 can be formed only in the pixel opening corresponding to the first color sub-pixel without a precise mask, and the second electrode layer 160 - 1 can be electrically connected to the partition portion 132 .

[0119] In step S145, a light emitting layer 150-2 corresponding to the second color, a second electrode layer 160-2 corresponding to the second color, and a first encapsulation layer 170-2 corresponding to the second color are sequentially formed to cover the entire surface.

[0120] Step S146 , forming an etching protection layer 210 - 2 covering the pixel opening of the second color sub-pixel.

[0121] Step S147 , removing the first encapsulation layer 170 - 2 , the light emitting layer 150 - 2 , and the second electrode layer 160 - 2 that are not covered by the etching protection layer 210 - 2 .

[0122] Step S148, removing the etching protection layer 210-2.

[0123] At this point, on the basis of forming the light-emitting layer 150 - 1 and the second electrode layer 160 - 1 , the light-emitting layer 150 - 2 and the second electrode layer 160 - 2 are formed only in the pixel opening corresponding to the second color sub-pixel, and the second electrode layer 160 - 2 can be electrically connected to the partition part 132 .

[0124] By analogy, by adopting the above similar steps, the light-emitting layer 150, the second electrode layer 160 and the first encapsulation layer 170 can be formed in the pixel openings corresponding to the sub-pixels of the third color or more other colors.

[0125] In step S150 , filter areas of different colors in the filter layer 180 may be formed in sequence by means of oil printing.

[0126] The present application also provides an electronic device, which includes the display panel provided by the present application.

[0127] In summary, the display panel, the manufacturing method of the display panel and the electronic device provided by the present application, by providing a filter layer that can cover the partition structure, the filter layer blocks the external light that shines on the partition structure, thereby reducing the reflective effect of the partition structure or other film layers on the partition structure, and improving the user's visual experience.
