DETAILED DESCRIPTION

[0096] 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.

[0097] In the description of the present application, it should be noted that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the application 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 orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0098] Improving the density of light-emitting devices in a display panel (i.e., pixel density) is an important way to improve the display effect. However, the display panels currently made using fine metal evaporation mask (FMM) technology are unable to further increase the density of light-emitting devices due to technical limitations. After long-term research, the inventors found that in order to solve the technical problem that the density of light-emitting devices cannot be further increased, an isolation structure is set in some display panels. When the light-emitting material layer and the cathode are evaporated in the entire layer, the light-emitting material layer and the cathode can be disconnected at the isolation structure position. Through multiple evaporation and multiple etching processes, light-emitting devices of different colors can be formed in different isolation openings. The above process is called light-emitting device patterning.

[0100] In the above-mentioned display panel, touch lines can be set in the same layer as the isolation structure. The distribution of the touch lines may affect the structural symmetry on both sides of the light-emitting device, so that different light-emitting devices have different light outputs at the same observation angle, thereby affecting the overall display effect of the display panel.

[0101] In order to solve the above problems, the inventor innovatively designed the following technical solution, and the specific implementation scheme of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that the defects existing in the above solutions in the prior art are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above technical problems and the solutions proposed in this embodiment below for the above problems should all be the contributions made by the inventor to the present application in the process of invention and creation, and should not be understood as the technical content known to those skilled in the art.

[0102] Please refer to Figure 1 and Figure 2 , Figure 1 The schematic diagram of the distribution of the isolation structure layer provided in this embodiment is illustrated. Figure 2 Example Figure 1 Schematic cross-sectional view of the AA position in FIG. In the present embodiment, the display panel 1 includes a substrate 11, an isolation structure layer 12, and a plurality of light-emitting devices 13. The isolation structure layer 12 is located on the substrate 11, and the isolation structure layer 12 includes an isolation structure 121 and a touch line 122 that are insulated from each other, that is, the isolation structure 121 and the touch line 122 are arranged on the same layer, and both have the same film layer structure. The isolation structure 121 encloses a plurality of isolation openings 1201 on the substrate 11, and there is a gap 1202 between adjacent isolation structures 121 and touch lines 122.

[0103] The plurality of light emitting devices 13 are at least partially located in the corresponding isolation openings 1201 , and the touch wiring 122 extends along a first direction (X direction in the figure) and is located between adjacent light emitting devices 13 in a second direction (Y direction in the figure), wherein the first direction intersects the second direction.

[0104] In the above structure, the touch line 122 is only located between the light-emitting devices adjacent to each other in the second direction, and will not be located between the light-emitting devices 13 adjacent to each other in the first direction. In this way, the display difference problem caused by the asymmetric structure of the light-emitting devices 13 on both sides when the touch line 122 is located between the light-emitting devices 13 adjacent to each other in the first direction can be improved, thereby ensuring that the display panel 1 has a good display effect and improving the user experience.

[0105] In a possible implementation of this embodiment, please refer to Figure 3 and Figure 4 , multiple light emitting devices 13 are arranged along a first direction (X direction in the figure) to form a pixel row 210, and at least part of the touch wiring 122 is arranged between adjacent pixel rows 210. In the first direction, multiple adjacent light emitting devices 13 form a pixel unit 30. For example, Figure 3As shown, a plurality of light emitting devices 13 are arranged in a straight line along a first direction to form a pixel row 30, wherein the plurality of light emitting devices 13 are arranged in a straight line along a first direction means that the center positions of the plurality of light emitting devices 13 are arranged in the first direction and are aligned with each other in the second direction; Figure 4 As shown, a plurality of light-emitting devices 13 are arranged non-linearly along a first direction to form a pixel row 30, wherein the plurality of light-emitting devices 13 are arranged non-linearly along the first direction means that the center positions of the plurality of light-emitting devices 13 are arranged in the first direction and are staggered with each other in a second direction. For example, the plurality of light-emitting devices 13 are arranged in a curve along the first direction to form a pixel row 30.

[0106] In another possible implementation of this embodiment, please refer to Figure 5 and Figure 6 , a plurality of adjacent light emitting devices 13 form a pixel unit 30, and a plurality of pixel units 30 are arranged along a first direction (the X direction in the figure) to form a pixel row 30. At least part of the touch wiring 122 is arranged between adjacent pixel rows 210. For example, Figure 5 As shown, a plurality of pixel units 30 are arranged in a straight line along a first direction to form a pixel row 30, wherein a plurality of pixel units 30 are arranged in a straight line along a first direction means that a plurality of pixel units 30 are arranged in a straight line along a first direction and are aligned with each other in a second direction; Figure 6 As shown, multiple pixel units 30 are arranged non-linearly along a first direction to form a pixel row 30, wherein multiple pixel units 30 are arranged non-linearly along the first direction means that multiple pixel units 30 are arranged along the first direction and are staggered with each other in a second direction, for example, multiple pixel units 30 are arranged in a curve along the first direction to form a pixel row 30.

[0107] In this embodiment, if Figure 3 and Figure 5 As shown, the touch line 122 may extend in a straight line in the first direction; Figure 4 and Figure 6 As shown, the touch line 122 may extend in a non-straight line in the first direction. The light emitting devices 13 located on opposite sides of the touch line 122 are equidistant from the touch line 122 in the second direction (the Y direction in the figure), that is, the touch line 122 is centrally disposed between adjacent light emitting devices 13 in the second direction.

[0108] In this embodiment, a plurality of pixel rows 210 are sequentially arranged along the second direction (the Y direction in the figure), and a plurality of light emitting devices 13 are arranged along the second direction (the Y direction in the figure) to form a pixel column 220, that is, the isolation openings 1201 where the light emitting devices 13 are located are also arranged along the second direction. A plurality of touch control traces 122 are also sequentially arranged along the second direction. Preferably, the first direction and the second direction are perpendicular to each other.

[0109] For further information, please refer to Figure 7and Figure 8 In this embodiment, the substrate 11 includes a connecting wire 111, the connecting wire 111 extends along the second direction (the Y direction in the figure) in the substrate 11, and a plurality of connecting wires 111 are distributed along the first direction (the X direction in the figure) in the substrate 11. The connecting wire 111 is connected to the touch wire 122, exemplarily, as Figure 3 and Figure 4 As shown, at the overlapping position of the orthographic projection of the connecting wiring 111 on the substrate 11 and the orthographic projection of the touch wiring 122 on the substrate 11 , the touch wiring 122 is electrically connected to the connecting wiring 111 through the film layer through hole at the overlapping position of the two.

[0110] The substrate 11 includes a substrate 1101 and a plurality of conductive layers 1102 stacked on the substrate 1101. The substrate 11 also includes an insulating layer 1103 located between adjacent conductive layers 1102. A pixel circuit for providing a driving signal for the light-emitting device 13 is formed in the substrate 11. In the present embodiment, the connecting wire 111 can be formed by the conductive layer 1102 in the substrate 11. Exemplarily, the connecting wire 111 can be formed by the conductive layer 1102 in the substrate 11 away from the substrate 1101. For example, when the substrate 11 includes four conductive layers M1, M2, M3 and M4, the connecting wire 111 can be formed by the conductive layer M4.

[0111] In this embodiment, please refer to Figure 7 The orthographic projections of the touch lines 122 and the connection lines 111 on the substrate 1101 are in a grid shape, that is, the touch lines 122 and the connection lines 111 form a grid-shaped touch pattern.

[0112] Optionally, the orthographic projection of the light-emitting device 13 on the substrate 11 does not overlap with the orthographic projection of the connecting wire 111 on the substrate 11. Such a setting can avoid the problem of uneven light-emitting surface of the light-emitting device caused by the connecting wire 111 being located below the light-emitting device 13, thereby ensuring that the light-emitting device 13 has good light-emitting effects at different angles.

[0113] Optionally, the orthographic projection of the pixel unit 30 on the substrate 1101 may be located within a corresponding grid in the grid pattern.

[0114] For further information, please refer to Fig. 9 and Fig.10 The display panel 1 also includes a pixel defining layer 14, which is located on one side of the substrate 11. The isolation structure layer 12 is located on the side of the pixel defining layer 14 away from the substrate 11. The pixel defining layer 14 defines a plurality of pixel openings 1401 on the substrate 11. The pixel openings 1401 are connected to the corresponding isolation openings 1201. Exemplarily, the orthographic projection of the pixel opening 1401 on the substrate 11 is located within the orthographic projection of the isolation opening 1201 on the substrate 11.

[0115] In this embodiment, the pixel defining layer 14 may be an organic pixel defining layer or an inorganic pixel defining layer. Preferably, the pixel defining layer 14 is an inorganic pixel defining layer. When the pixel defining layer 14 is an inorganic pixel defining layer, the pixel defining layer 14 may be a single layer structure of silicon oxide (SiOx) or silicon nitride (SiNx), or a stacked layer structure formed alternately of silicon oxide and silicon nitride.

[0116] Please refer again Fig. 9 The pixel defining layer 14 between adjacent pixel openings 1401 along the first direction (X direction in the figure) has a first size d1 in the first direction, and the first sizes d1 of the pixel defining layer 14 between different adjacent pixel openings 1401 are equal.

[0117] The pixel defining layer 14 between adjacent pixel openings 1401 along the second direction (Y direction in the figure) has a second size d2 in the second direction, and the second sizes d2 of the pixel defining layers 1401 between different adjacent pixel openings 1401 are equal.

[0118] Further, the first size d1 is smaller than the second size d2. Optionally, the second size d2 is larger than the first size d1 and smaller than twice the first size d2.

[0119] In this embodiment, the first size d1 is 12μm-16μm. Exemplarily, the size d1 includes 12μm, 12.1μm, 12.4μm, 12.6μm, 12.9μm, 13.5μm, 13.9μm, 14.4μm, 14.6μm, 15.1μm, 15.3μm, 15.6μm or 16μm, etc.

[0120] In this embodiment, the first dimension d2 is 18μm-30μm. Exemplarily, the dimension d2 includes 18μm, 20μm, 21.5μm, 22.3μm, 23.6μm, 24.6μm, 26.1μm, 27μm, 27.8μm, 28.6μm, 29μm, 29.6μm or 30μm, etc.

[0121] For example, please refer again to Figure 3 or Figure 4 , the size of the light emitting device 13 in the first direction (X direction in the figure) is smaller than the size of the light emitting device 13 in the second direction (Y direction in the figure), the sizes of the light emitting devices 13 of different light emitting colors in the second direction are equal, while the sizes of the light emitting devices 13 of different light emitting colors in the first direction are unequal. With such a design, the influence on the light emitting area of ​​the light emitting device 13 can be reduced while increasing the width of the touch line 122 extending along the first direction, and the light emitting efficiency of the light emitting device 13 and the touch performance of the touch line 122 can be taken into account at the same time.

[0122] For further information, please refer to Fig.11 , in the direction away from the substrate 11, the light emitting device 13 includes a first electrode 131, a light emitting material layer 132 and a second electrode 133 which are stacked, the first electrode 131 being distributed at intervals on one side of the substrate 11. For example, the first electrode 131 is distributed on the substrate 11, the pixel opening 1401 exposes at least part of the first electrode 131, and the first electrode 131 is connected to a pixel circuit (not shown in the figure) in the substrate 11. The light emitting material layer 132 extends from the pixel opening 1401 to the side of the pixel defining layer 14 away from the substrate 11, and the second electrode 133 extends from the pixel opening 1401 to the side of the pixel defining layer 14 away from the substrate 11 and is connected to the isolation structure 121. For example, the second electrode 133 extends from the pixel opening 1401 to the side of the pixel defining layer 14 away from the substrate 11 and overlaps with the isolation structure 121, wherein the isolation structure 121 is a conductive isolation structure. For example, the first electrode 131 can be an anode of the light emitting device 13, and the second electrode 133 can be a cathode of the light emitting device 13.

[0123] The isolation structure 121 can enclose a plurality of isolation openings 1201. The setting of the isolation structure 121 can form film layers of light-emitting devices of different colors in different isolation openings 1201 without the need for a fine metal mask, thereby reducing the manufacturing cost of the display panel. The isolation structure 121 can isolate the light-emitting material layer 132 and the second electrode 133 in the light-emitting device 13, so that different light-emitting devices 13 are independent of each other, so as to improve the crosstalk between adjacent light-emitting devices 13 and enhance the display effect. Adjacent light-emitting devices 13 can be independently packaged to improve the packaging yield. At the same time, due to the existence of the isolation structure 121, the light-emitting material layer 132 and the second electrode 133 in the light-emitting device 13 of each color in the display panel can be first prepared on the entire surface and then patterned, thereby eliminating the fine metal mask to save the manufacturing cost of the display panel 1.

That is, the touch line 122 extends in a direction parallel to the short side of the orthographic projection of the pixel opening 1401 on the substrate 11, so that when the line width of the touch line 122 is adjusted, the impact on the opening area of ​​the pixel opening 1401 can be minimized. Under the premise of increasing the line width of the touch line 122 to improve the touch performance, the impact on the aperture ratio is minimized.
