[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0020] It should be noted that similar reference numerals 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. It should be noted that, unless otherwise specified, different features in the embodiments of this application can be combined with each other.
[0021] Furthermore, when using terms such as "above," "above," "below," "below," and "relative" to define the positional relationship between two elements, this includes not only the state where the two elements are directly connected, but also the state where the two elements are separated by gaps or other elements. In addition, the terms "first," "second," and "third," etc., are only used for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.
[0022] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.
[0023] The display panel in the related technology includes a substrate, a pixel defining layer located on one side of the substrate, and a light-emitting unit located within a pixel opening formed by the pixel defining layer. The light-emitting unit emits light to realize the display function of the display panel.
[0024] The display panel also features touch functionality, primarily supporting both finger touch and stylus touch. Stylus-enabled display panels mainly achieve this through electromagnetic resonance (EMR). When the stylus moves on the display screen, the electromagnetic coils in the EMR module communicate electromagnetically with the stylus. By calculating the electromagnetic signal quantities of the electromagnetic coils in different channels, the coordinates of the stylus are determined.
[0025] However, the external electromagnetic resonant module design in related technologies, where the electromagnetic electrode film layer of the display panel is attached to the back of the display panel, makes the display panel thicker, more complex in structure, and more expensive.
[0026] To address the aforementioned technical problems, the following innovative technical solutions are designed. The specific implementation schemes of this application will be described in detail below with reference to the accompanying drawings. It should be noted that the deficiencies in the existing solutions are the result of practical experience and careful research. Therefore, the discovery process of the aforementioned technical problems and the solutions proposed in this embodiment below should be considered contributions made to this application during the invention process, and should not be construed as technical content known to those skilled in the art.
[0027] Please see Figures 1-4 This embodiment provides a display panel, which includes a substrate 1, a pixel defining layer 6, a plurality of light-emitting units 5, a first electrode layer 7, and a second electrode layer 8.
[0028] The pixel defining layer 6 is located on one side of the substrate 1, and the pixel defining layer 6 encloses and forms a plurality of pixel openings 61; at least a portion of the light-emitting unit 5 is located within the pixel openings 61.
[0029] The first electrode layer 7 is located on the side of the light-emitting unit 5 away from the substrate 1. The first electrode layer 7 includes a plurality of first touch electrodes 72, a plurality of first electromagnetic electrodes 71 and a first touch connection line 74. The first touch connection line 74 connects the plurality of first touch electrodes 72. The orthographic projection of the first touch electrodes 72 on the substrate 1 is offset from the orthographic projection of the first electromagnetic electrodes 71 on the substrate 1.
[0030] The second electrode layer 8 is located on the side of the first electrode layer 7 away from the substrate 1. The second electrode layer 8 includes a plurality of second touch electrodes 81, a plurality of second electromagnetic electrodes 82, and a second touch connection line 83. The second touch connection line 83 connects the plurality of second touch electrodes 81. The orthographic projection of the second touch electrode 81 on the substrate 1 is offset from the orthographic projection of the second electromagnetic electrode 82 on the substrate 1. The orthographic projection of the second touch electrode 81 on the substrate 1 is at least partially offset from the orthographic projection of the first touch electrode 72 on the substrate 1.
[0031] The combination of the first touch electrode 72 and the second touch electrode 81 enables the touch function of the display panel. The first electromagnetic electrode 71 and the second electromagnetic electrode 82 enable the electromagnetic function of the display panel. The first electromagnetic electrode 71 and the first touch electrode 72 are arranged in the same layer, and the second electromagnetic electrode 82 and the second touch electrode 81 are arranged in the same layer. Thus, the electromagnetic electrode film layer does not need to be externally attached to the back of the display panel. Furthermore, the thickness of the film layer of the display panel is not increased when the first electromagnetic electrode 71 and the second electromagnetic electrode 82 are arranged. Therefore, compared to the solution of externally attaching the electromagnetic electrode film layer to the back of the display panel, this embodiment integrates the electromagnetic electrode and the touch electrode in the same layer, thus integrating the electromagnetic pen function with the OLED display. This reduces the thickness of the external module and eliminates the need for a complex design for the first electromagnetic electrode 71 and the second electromagnetic electrode 82, thereby reducing the cost of the display panel and simplifying its structure.
[0032] The orthographic projection of the first touch electrode 72 on the substrate 1 is offset from the orthographic projection of the first electromagnetic electrode 71 on the substrate 1. That is, the first touch electrode 72 and the first electromagnetic electrode 71, which are located on the same layer, are insulated from each other. In this way, the first touch electrode 72 and the first electromagnetic electrode 71 do not affect each other.
[0033] The orthographic projection of the second touch electrode 81 on the substrate 1 is offset from the orthographic projection of the second electromagnetic electrode 82 on the substrate 1. That is, the second touch electrode 81 and the second electromagnetic electrode 82, which are located on the same layer, are insulated from each other. In this way, the second touch electrode 81 and the second electromagnetic electrode 82 do not affect each other.
[0034] The orthographic projection of the second touch electrode 81 on the substrate 1 is at least partially offset from the orthographic projection of the first touch electrode 72 on the substrate 1. That is, the first touch electrode 72 and the second touch electrode 81 on different layers are offset. In this way, the overlapping area of the first touch electrode 72 and the second touch electrode 81 can be reduced, thereby reducing the planar capacitance between the first touch electrode 72 and the second touch electrode 81, increasing the amount of touch signal, and thus improving the touch performance of the display panel.
[0035] Based on the above design, in this embodiment, by setting the first electromagnetic electrode 71 and the first touch electrode 72 in the same layer, setting the second electromagnetic electrode 82 and the second touch electrode 81 in the same layer, and setting the second touch electrode 81 and the first touch electrode 72 at least partially offset, electromagnetic electrodes can be integrated in the touch film layer. While integrating the electromagnetic pen function in the display screen, the planar capacitance between the first touch electrode 72 and the second touch electrode 81 can be reduced, the touch signal quantity can be increased, and thus the touch performance of the display panel can be improved.
[0036] In some possible implementations, please refer again. Figures 1-4 The orthographic projection of the second touch electrode 81 on the substrate 1 coincides with the orthographic projection of the first electromagnetic electrode 71 on the substrate 1.

[0038] The second touch electrode 81 and the first electromagnetic electrode 71 are identical in shape and size, and their orthographic projections on the substrate 1 completely overlap. Similarly, the second electromagnetic electrode 82 and the first touch electrode 72 are identical in shape and size, and their orthographic projections on the substrate 1 completely overlap. This arrangement of the second touch electrode 81 and the first touch electrode 72 completely offsets them, further reducing the planar capacitance between the first touch electrode 72 and the second touch electrode 81, increasing the touch signal strength, and ultimately improving the touch performance of the display panel.
[0039] Optionally, the orthographic projection of the second touch electrode 81 on the substrate 1 is rectangular, rhomboid, triangular, or circular.
[0040] Optionally, the orthographic projection of the second electromagnetic electrode 82 onto the substrate 1 is rectangular, rhomboid, triangular, or circular.
[0041] Optionally, the shape of the orthographic projection of the second touch electrode 81 on the substrate 1 is the same as the shape of the orthographic projection of the second electromagnetic electrode 82 on the substrate 1.
[0042] The first touch electrode 72, the second touch electrode 81, the first electromagnetic electrode 71, and the second electromagnetic electrode 82 can be designed as rectangles, rhombuses, triangles, or circles according to actual needs, thus increasing the flexibility in designing the first touch electrode 72, the second touch electrode 81, the first electromagnetic electrode 71, and the second electromagnetic electrode 82.
[0043] The first touch electrode 72, the second touch electrode 81, the first electromagnetic electrode 71, and the second electromagnetic electrode 82 in the same display panel have the same shape, which can improve the touch effect of the display panel.
[0044] Optionally, one of the first touch electrode 72 and the second touch electrode 81 is a touch receiving electrode and the other is a touch transmitting electrode; one of the first electromagnetic electrode 71 and the second electromagnetic electrode 82 is an electromagnetic receiving electrode and the other is an electromagnetic transmitting electrode.
[0045] For example, the first touch electrode 72 is a touch receiving electrode, and the second touch electrode 81 is a touch transmitting electrode. The combination of the first touch electrode 72 and the second touch electrode 81 can realize the capacitive touch of the display panel; the first electromagnetic electrode 71 is an electromagnetic receiving electrode, and the second electromagnetic electrode 82 is an electromagnetic transmitting electrode. The combination of the first electromagnetic electrode 71 and the second electromagnetic electrode 82 can realize the electromagnetic touch of the display panel.
[0046] In some possible implementations, please refer again. Figure 3 The same first touch connection line 74 connects to a plurality of first touch electrodes 72 arranged along the first direction X.
[0047] The first direction X is the row direction of the display panel. The same first touch connection line 74 electrically connects the first touch electrodes 72 in the same row, so that the first touch electrodes 72 in the same row form a touch strip extending along the first direction X.
[0048] The number of first touch connection lines 74 is multiple. Multiple first touch connection lines 74 can electrically connect multiple first touch electrodes 72 into multiple rows. That is, multiple first touch electrodes 72 can be connected through multiple first touch connection lines 74 to form multiple touch strips extending along the first direction X.
[0049] Optionally, please see again Figure 3 The first electrode layer 7 also includes a plurality of first electromagnetic connection lines 73, and the same first electromagnetic connection line 73 connects to a plurality of first electromagnetic electrodes 71 arranged along the first direction X.

[0052] Optionally, please see Figure 3 and Figure 5 The display panel includes a display area AA and a non-display area AB surrounding at least a portion of the display area AA. The display area AA includes a first side AA1 and a second side AA2 that are disposed opposite to each other. The first side AA1 and the second side AA2 are arranged along a first direction X.
[0053] The display panel also includes a chip 13, which is located in the non-display area AB. A first touch connection line 74 extends from the first side AA1 to the non-display area AB and is electrically connected to the chip 13. A first electromagnetic connection line 73 extends from the second side AA2 to the non-display area AB and is electrically connected to the chip 13.
[0054] Chip 13 is located on the lower edge of the display panel.

[0055] The first electromagnetic connection line 73 passes through the second side AA2 to the left edge of the display panel, then extends from the left edge of the display panel to the bottom edge of the display panel and is electrically connected to the chip 13.
[0056] Thus, the first electromagnetic connection line 73 and the first touch connection line 74, which are located on the same layer, are led out from different sides of the display panel and electrically connected to the chip 13, which makes it less likely for the first electromagnetic connection line 73 and the first touch connection line 74 to interfere with each other.

[0060] The first touch connection line 74, the first electromagnetic connection line 73, the first touch electrode 72, and the first electromagnetic electrode 71 located on the same layer are made of the same material. That is, the first touch connection line 74, the first electromagnetic connection line 73, the first touch electrode 72, and the first electromagnetic electrode 71 can be formed by the same process, thereby reducing the process cost of forming the first touch connection line 74, the first electromagnetic connection line 73, the first touch electrode 72, and the first electromagnetic electrode 71.

[0079] The plurality of second touch traces 811 of the second touch electrode 81 are staggered with the plurality of second electromagnetic traces 821 of the corresponding second electromagnetic electrode 82. That is, the plurality of second touch traces 811 of the second touch electrode 81 extend into the corresponding second electromagnetic electrode 82 but do not contact the second electromagnetic traces 821 of the corresponding second electromagnetic electrode 82; the plurality of second electromagnetic traces 821 of the second electromagnetic electrode 82 extend into the corresponding second touch electrode 81 but do not contact the second touch traces 811 of the corresponding second touch electrode 81. In this way, the horizontal space occupied by the second touch electrode 81 and the second electromagnetic electrode 82 on the display panel can be reduced, and the second touch electrode 81 and the second electromagnetic electrode 82 do not interfere with each other.
[0080] Optionally, the second touch trace 811 includes a third break 8111. The distance D3 between the orthographic projection of the side of the third break 8111 facing the second electromagnetic trace 821 onto the substrate 1 and the edge of the orthographic projection of the second electromagnetic trace 821 onto the substrate 1 is greater than or equal to 3μm and less than or equal to 8μm. For example, the distance D3 can be 3μm, 4μm, 5μm, 6μm, 7μm, or 8μm, etc. By reasonably setting the distance D3, the second touch electrode 81 and the second electromagnetic electrode 82 are less likely to interfere with each other.

[0083] The pattern formed by the orthographic projection of the second touch electrode 81 on the substrate 1 refers to the pattern formed by the orthographic projection of the second touch electrode 81 on the substrate 1 as a whole. The pattern formed by the orthographic projection of the first touch electrode 72 on the substrate 1 refers to the pattern formed by the orthographic projection of the first touch electrode 72 on the substrate 1 as a whole. The orthographic projection of the first touch trace 721 of the first touch electrode 72 on the substrate 1 is completely offset from the orthographic projection of the second touch trace 811 of the second touch electrode 81 on the substrate 1. The pattern formed by the orthographic projection of the first touch electrode 72 on the substrate 1 as a whole overlaps with the pattern formed by the orthographic projection of the second touch electrode 81 on the substrate 1 as a whole. In this way, while reducing the planar capacitance between the first touch electrode 72 and the second touch electrode 81, the horizontal width occupied by the first touch electrode 72 and the second touch electrode 81 on the display panel is not excessively increased.

[0085] In this way, the first touch trace 721 and the first electromagnetic trace 711 are less likely to block the light emitted by the light-emitting unit 5, thus not affecting the display effect of the display panel.
[0086] Optionally, the orthographic projection of the first touch trace 721 on the substrate 1 surrounds the orthographic projection of the pixel opening 61 on the substrate 1; and / or, the orthographic projection of the first electromagnetic trace 711 on the substrate 1 surrounds the orthographic projection of the pixel opening 61 on the substrate 1.
[0087] In this way, while making it less likely for the first touch trace 721 and the first electromagnetic trace 711 to block the light emitted by the light-emitting unit 5, the arrangement space of the first touch trace 721 and the first electromagnetic trace 711 can be more reasonable.
[0088] Optionally, please see Figure 7 The orthographic projection of the second touch trace 811 on the substrate 1 and the orthographic projection of the pixel opening 61 on the substrate 1 are spaced apart, and / or the orthographic projection of the second electromagnetic trace 821 on the substrate 1 and the orthographic projection of the pixel opening 61 on the substrate 1 are spaced apart.
[0089] In this way, the second touch trace 811 and the second electromagnetic trace 821 are less likely to block the light emitted by the light-emitting unit 5, thus not affecting the display effect of the display panel.
[0090] Optionally, the orthographic projection of the second touch trace 811 on the substrate 1 surrounds the orthographic projection of the pixel opening 61 on the substrate 1; and / or, the orthographic projection of the second electromagnetic trace 821 on the substrate 1 surrounds the orthographic projection of the pixel opening 61 on the substrate 1.
[0091] In this way, while making it less likely for the second touch trace 811 and the second electromagnetic trace 821 to block the light emitted by the light-emitting unit 5, the arrangement space of the second touch trace 811 and the second electromagnetic trace 821 can be more reasonable.

[0098] The second insulating layer 12 can protect the second electrode layer 8 to prevent the metal of the second electrode layer 8 from being scratched or corroded.
[0099] A third insulating layer 11 is also provided between the first electrode layer 7 and the second electrode layer 8. The material of the third insulating layer 11 includes inorganic materials. The third insulating layer 11 can separate the first electrode layer 7 and the second electrode layer 8 to prevent electrical contact between the first electrode layer 7 and the second electrode layer 8.
[0100] Optionally, along the thickness direction Z of the substrate 1, the thickness H1 of the first insulating layer 10 is greater than or equal to 0.3 μm and less than or equal to 0.6 μm. For example, the thickness H1 can be 3 μm, 4 μm, 5 μm, 6 μm, 7 μm or 8 μm, etc. By reasonably setting the thickness H1, the first electrode layer 7 can be made flatter.
[0101] Preferably, along the thickness direction Z of the substrate 1, the thickness H2 of the second insulating layer 12 is greater than or equal to 0.3 μm and less than or equal to 0.6 μm. For example, the thickness H2 can be 3 μm, 4 μm, 5 μm, 6 μm, 7 μm or 8 μm, etc. By reasonably setting the thickness H2, the protective effect of the second insulating layer 12 on the second electrode layer 8 can be improved.
[0102] For some possible implementations, please refer to Figure 9 This application also provides a method for manufacturing a display panel, the method comprising: S10: Provide substrate 1.
[0103] S11: A pixel defining layer 6 is formed on one side of the substrate 1, and the pixel defining layer 6 encloses and forms a plurality of pixel openings 61.
[0104] S12: A plurality of light-emitting units 5 are formed, at least a portion of which are located within the pixel opening 61.
[0105] S13: A first electrode layer 7 is formed on the side of the light-emitting unit 5 away from the substrate 1. The first electrode layer 7 includes a plurality of first touch electrodes 72, a plurality of first electromagnetic electrodes 71 and a first touch connection line 74. The first touch connection line 74 connects the plurality of first touch electrodes 72. The orthographic projection of the first touch electrodes 72 on the substrate 1 is offset from the orthographic projection of the first electromagnetic electrodes 71 on the substrate 1.
[0106] Please see Figure 3 and Figure 10 The first electromagnetic electrode 71, the first touch electrode 72, the first electromagnetic connection line 73, and the first touch connection line 74 are formed on the side of the light-emitting unit 5 away from the substrate 1 using the same process. In this way, the process cost of forming the first electromagnetic electrode 71, the first touch electrode 72, the first electromagnetic connection line 73, and the first touch connection line 74 can be reduced.
[0107] S14: A second electrode layer 8 is formed on the side of the first electrode layer 7 away from the substrate 1. The second electrode layer 8 includes a plurality of second touch electrodes 81, a plurality of second electromagnetic electrodes 82, and a second touch connection line 83.

In this way, the process cost of forming the second electromagnetic electrode 82, the second touch electrode 81, the second electromagnetic connection line 84, and the second touch connection line 83 can be reduced.
[0109] In this embodiment, the electromagnetic electrodes and touch electrodes are arranged on the same layer in the display panel formed by the above method, that is, the electromagnetic pen function is integrated with the OLED display screen. This can reduce the thickness of the external module, and the first electromagnetic electrode 71 and the second electromagnetic electrode 82 do not require a more complex design, thereby reducing the cost of the display panel and making the structure of the display panel simpler.
[0110] By using the above method, the orthographic projection of the second touch electrode 81 on the substrate 1 is at least partially offset from the orthographic projection of the first touch electrode 72 on the substrate 1. That is, the first touch electrode 72 and the second touch electrode 81 on different layers are offset. In this way, the overlapping area of the first touch electrode 72 and the second touch electrode 81 can be reduced, thereby reducing the planar capacitance between the first touch electrode 72 and the second touch electrode 81, increasing the touch signal quantity, and thus improving the touch performance of the display panel.
