Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a display panel and a display device. Background Technology

[0002] Currently, touch display panels mainly support two methods: finger touch and stylus touch. Display panels supporting stylus touch primarily achieve this by attaching an electromagnetic resonance (EMR) module externally to the back of the display panel. When the stylus moves on the 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.

[0003] Since the electromagnetic resonant module itself has a certain thickness, attaching it externally will increase the thickness of the display module, which is not conducive to making the screen thinner and lighter. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a display panel and a display device, which enable the display panel to support finger touch and stylus touch, and reduce the thickness of the display panel to reduce the manufacturing cost of the display panel.

[0005] In a first aspect, embodiments of this application provide a display panel, including: Substrate; The touch layer is located on one side of the substrate. The touch layer includes capacitive touch units and electromagnetic touch units. The capacitive touch units are used to sense a first input operation, and the electromagnetic touch units are used to sense a second input operation. The capacitive touch unit includes a first capacitive electrode and a second capacitive electrode whose extension directions intersect; the electromagnetic touch unit includes a first electromagnetic electrode and a second electromagnetic electrode whose extension directions intersect; at least one of the first electromagnetic electrode and the second electromagnetic electrode is disposed in a different layer from the first capacitive electrode, or at least one of the first electromagnetic electrode and the second electromagnetic electrode is disposed in a different layer from the second capacitive electrode. The capacitive touch unit also includes a capacitive connection portion, which includes a first capacitive connection portion and a second capacitive connection portion; two adjacent first capacitive electrodes are electrically connected through at least one first capacitive connection portion, and two adjacent second capacitive electrodes are electrically connected through at least one second capacitive connection portion. The electromagnetic touch unit also includes an electromagnetic connection part, which includes a first electromagnetic connection part and a second electromagnetic connection part; two adjacent first electromagnetic electrodes are electrically connected through at least one first electromagnetic connection part, and two adjacent second electromagnetic electrodes are electrically connected through at least one second electromagnetic connection part; the first electromagnetic connection part is disposed on the same layer as one of the first capacitor connection part and the second capacitor connection part, or the second electromagnetic connection part is disposed on the same layer as one of the first capacitor connection part and the second capacitor connection part.

[0006] On the other hand, embodiments of the present invention provide a display device including the display panel described above.

[0007] The display panel and display device provided in this invention, by centrally arranging the capacitive touch unit and the electromagnetic touch unit within the touch layer of the display panel, avoids externally attaching the electromagnetic touch unit to the side of the display panel away from the light-emitting side, thus facilitating a reduction in the thickness of the display panel. Furthermore, it avoids the need for a separate assembly station during the manufacturing process to align and attach the electromagnetic touch unit and the display panel, thereby reducing the number of manufacturing steps and lowering the manufacturing cost of the display panel.

[0008] Furthermore, by having at least one of the first electromagnetic electrode and the second electromagnetic electrode disposed in a different layer from the first capacitor electrode, or by having at least one of the first electromagnetic electrode and the second electromagnetic electrode disposed in a different layer from the second capacitor electrode, the embodiments of the present invention can avoid the placement of the first electromagnetic electrode or the second electromagnetic electrode occupying the placement space of the first capacitor electrode or the second capacitor electrode. This can reduce the mutual influence between electromagnetic touch and capacitive touch, and is beneficial to setting the area of ​​the first capacitor electrode or the second capacitor electrode as large as possible to improve capacitive touch performance, and setting the area of ​​the first electromagnetic electrode or the second electromagnetic electrode as large as possible to improve electromagnetic touch performance.

[0009] Furthermore, by having the first electromagnetic connection portion and one of the first capacitor connection portion and the second capacitor connection portion disposed in the same layer, or by having the second electromagnetic connection portion and one of the first capacitor connection portion and the second capacitor connection portion disposed in the same layer, the first electromagnetic connection portion and one of the first capacitor connection portion and the second capacitor connection portion can be formed simultaneously in the same process, or the second electromagnetic connection portion and one of the first capacitor connection portion and the second capacitor connection portion can be formed simultaneously in the same process. This is beneficial for reducing the thickness of the display panel and reducing the number of manufacturing steps for the display panel. Attached Figure Description

Detailed Implementation

[0012] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0013] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0014] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0015] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0016] This invention provides a display panel, such as... Figure 1 As shown, Figure 1 This is a top view schematic diagram of a display panel provided in an embodiment of the present invention. Figure 2 for Figure 1 An enlarged schematic diagram of region A1 in the middle. Figure 3 for Figure 2 A cross-sectional view along BB' shows a display panel including a substrate 1 and a touch layer 2. The touch layer 2 is located on one side of the substrate 1 and includes a capacitive touch unit 21 and an electromagnetic touch unit 22. The capacitive touch unit 21 is used to sense a first input operation, and the electromagnetic touch unit 22 is used to sense a second input operation. The first input operation includes a finger touching the display panel. The second input operation includes a stylus touching the display panel. The stylus can emit electromagnetic waves and has a structure including an RC resonant circuit, a pressure-sensitive capacitor, and a coil.

[0017] For example, such as Figure 3 As shown, the display panel also includes a display film layer 30, in which sub-pixels (not shown) are disposed. The touch layer 2 is located on the side of the display film layer 30 away from the substrate 1.

[0018] In this embodiment of the invention, by integrating the capacitive touch unit 21 and the electromagnetic touch unit 22 into the touch layer 2, the electromagnetic touch unit 22 can be avoided by externally mounting it on the side of the display panel away from the light-emitting side, thus reducing the thickness of the display panel. Furthermore, it also avoids the need to set up a separate assembly station in the manufacturing process to align and attach the electromagnetic touch unit 22 and the display panel, which helps to reduce the manufacturing steps of the display panel and lower the manufacturing cost of the display panel.

[0019] For example, such as Figure 1 As shown, in this embodiment of the invention, the capacitive touch unit 21 can be configured to include a first capacitive electrode 211 and a second capacitive electrode 212 whose extension directions intersect. Figure 1The diagram illustrates a first capacitor electrode 211 extending along a first direction h11 and a second capacitor electrode 212 extending along a second direction h12, where the first direction h11 and the second direction h12 intersect. For example, one of the first capacitor electrode 211 and the second capacitor electrode 212 transmits a touch driving signal, and the other transmits a touch sensing signal.

[0020] like Figure 1 As shown, the electromagnetic touch unit 22 includes a first electromagnetic electrode 221 and a second electromagnetic electrode 222 whose extending directions intersect. Figure 1 and Figure 2 The diagram illustrates a first electromagnetic electrode 221 extending along a first direction h11 and a second electromagnetic electrode 222 extending along a second direction h12. The first electromagnetic electrode 221 is used to form a first electromagnetic coil, and the second electromagnetic electrode 222 is used to form a second electromagnetic coil.

[0021] In this embodiment of the invention, at least one of the first electromagnetic electrode 221 and the second electromagnetic electrode 222 is disposed in a different layer from the first capacitor electrode 211, or at least one of the first electromagnetic electrode 221 and the second electromagnetic electrode 222 is disposed in a different layer from the second capacitor electrode 212. That is, the first electromagnetic electrode 221 and the first capacitor electrode 211 are disposed in a different layer, or the second electromagnetic electrode 222 and the first capacitor electrode 211 are disposed in a different layer, or both the first electromagnetic electrode 221 and the second electromagnetic electrode 222 are disposed in a different layer from the first capacitor electrode 211; or the second electromagnetic electrode 222 and the first capacitor electrode 211 are disposed in a different layer, or both the first electromagnetic electrode 221 and the second electromagnetic electrode 222 are disposed in a different layer from the first capacitor electrode 211.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, Figure 4 for Figure 2 A cross-sectional schematic diagram along CC' shows that the touch layer 2 includes a first touch metal layer TM1, a second touch metal layer TM2 and a third touch metal layer TM3 stacked together, a first touch insulating layer TS1 located between the first touch metal layer TM1 and the second touch metal layer TM2, and a second touch insulating layer TS2 located between the second touch metal layer TM2 and the third touch metal layer TM3.

[0023] In this embodiment of the invention, the first electromagnetic electrode 221 can be located in the first touch metal layer TM1, the second electromagnetic electrode can be located in the second touch metal layer TM2, and the first capacitor electrode 211 and the second capacitor electrode 212 can be located in the third touch metal layer TM3.

[0024] Based on this configuration, the first electromagnetic electrode 221 or the second electromagnetic electrode 222 can be prevented from encroaching on the position of the first capacitor electrode 211, thus ensuring the area of ​​the first capacitor electrode 211. Alternatively, the first electromagnetic electrode 221 or the second electromagnetic electrode 222 can be prevented from encroaching on the position of the second capacitor electrode 212, thus ensuring the area of ​​the second capacitor electrode 212. This reduces the mutual influence between electromagnetic touch and capacitive touch, making the effect of capacitive touch close to or the same as the case where no electromagnetic touch unit 22 is provided in the display panel, and making the effect of electromagnetic touch close to or the same as the case where no capacitive touch unit 21 is provided in the display panel.

[0025] For example, the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3 mentioned above include metal materials such as molybdenum, molybdenum alloy, aluminum, aluminum alloy, copper, copper alloy, titanium, or titanium alloy. For instance, in embodiments of the present invention, at least one of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3 may be configured to include a titanium-aluminum-titanium stacked structure.

[0026] In this embodiment of the invention, the first capacitor electrode 211 and the second capacitor electrode 212 do not overlap at least partially in the direction h2 perpendicular to the plane of the substrate, and the two can be disposed in the same layer or in different layers; the first electromagnetic electrode 221 and the second electromagnetic electrode 222 do not overlap at least partially in the direction h2 perpendicular to the plane of the display panel, and the two can be disposed in the same layer or in different layers. Figure 2 The first capacitor electrode 211 and the second capacitor electrode 212 are disposed in the same layer on the third touch metal layer TM3, and the first electromagnetic electrode 221 and the second electromagnetic electrode 222 are disposed in different layers as an illustration.

[0027] For example, such as Figure 2 As shown, the capacitive touch unit 21 also includes a capacitive connection portion 213, which includes a first capacitive connection portion 2131 and a second capacitive connection portion 2132; two adjacent first capacitive electrodes 211 on the first direction h11 are electrically connected through at least one first capacitive connection portion 2131, and two adjacent second capacitive electrodes 212 on the second direction h12 are electrically connected through at least one second capacitive connection portion 2132. Figure 2 The diagram illustrates two adjacent first capacitor electrodes 211 on the first direction h11 connected by a first capacitor connection part 2131, and two adjacent second capacitor electrodes 212 on the second direction h12 connected by a second capacitor connection part 2132.

[0028] In this embodiment of the invention, the first capacitor connection portion 2131 and the second capacitor connection portion 2132 at least partially overlap in the direction h2 perpendicular to the plane of the substrate, and are disposed in different layers. For example, the first capacitor connection portion 2131 may be located in one of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3, and the second capacitor connection portion 2132 may be located in any of the other two layers of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3. Figure 2 and Figure 4 The diagram illustrates a first capacitor connection 2131 located in the first touch metal layer TM1 and a second capacitor connection 2132 located in the second touch metal layer TM2.

[0029] Continue to refer to Figure 2 As shown, the electromagnetic touch unit 22 also includes an electromagnetic connection part 220, which includes a first electromagnetic connection part 2201 and a second electromagnetic connection part 2202; two adjacent first electromagnetic electrodes 221 are electrically connected through at least one first electromagnetic connection part 2201, and two adjacent second electromagnetic electrodes 222 are electrically connected through at least one second electromagnetic connection part 2202.

[0030] In this embodiment of the invention, the first electromagnetic connection portion 2201 and the second electromagnetic connection portion 2202 at least partially overlap in a direction h2 perpendicular to the plane of the substrate, and are disposed in different layers. For example, the first electromagnetic connection portion 2201 may be located in one of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3, and the second electromagnetic connection portion 2202 may be located in any of the other two layers of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3. Figure 2 , Figure 3 and Figure 4 The diagram illustrates a first electromagnetic connection 2201 located in the first touch metal layer TM1 and a second electromagnetic connection 2202 located in the second touch metal layer TM2.

[0031] In this embodiment of the invention, the first electromagnetic connection portion 2201 is disposed in the same layer as one of the first capacitor connection portion 2131 and the second capacitor connection portion 2132, or the second electromagnetic connection portion 2202 is disposed in the same layer as one of the first capacitor connection portion 2131 and the second capacitor connection portion 2132. Based on this arrangement, when manufacturing the display panel, one of the first electromagnetic connection portion 2201 and the first capacitor connection portion 2131 and the second capacitor connection portion 2132 can be formed simultaneously in the same patterning process, or the second electromagnetic connection portion 2202 and the first capacitor connection portion 2131 and the second capacitor connection portion 2132 can be formed simultaneously in the same patterning process. This simplifies the manufacturing process of the display panel and further reduces its thickness.

[0032] Figure 4 The second electromagnetic connection portion 2202 and the second capacitor connection portion 2132 are disposed on the same layer of the second touch metal layer TM2 as an illustration.

[0033] In embodiments of the present invention, such as Figure 2 As shown, along direction h2 perpendicular to the plane of substrate 1, any capacitor connection 213 and any electromagnetic connection 220 are offset from each other. That is, along direction h2 perpendicular to the plane of substrate 1, the first capacitor connection 2131 and the first electromagnetic connection 2201 are offset from each other, the first capacitor connection 2131 and the second electromagnetic connection 2202 are offset from each other, the second capacitor connection 2132 and the first electromagnetic connection 2201 are offset from each other, and the second capacitor connection 2132 and the second electromagnetic connection 2202 are offset from each other. Based on this arrangement, while ensuring that any capacitor connection 213 and any electromagnetic connection 220 are mutually insulated, the first electromagnetic connection 2201 can be disposed in the same layer as one of the first capacitor connection 2131 and the second capacitor connection 2132, or the second electromagnetic connection 2202 can be disposed in the same layer as one of the first capacitor connection 2131 and the second capacitor connection 2132, so as to reduce the thickness of the display panel and simplify the manufacturing process of the display panel.

[0034] For example, in embodiments of the present invention, the first electromagnetic connection portion 2201 and the second electromagnetic connection portion 2202 may be disposed in different layers; and the first electromagnetic electrode 221 and the first electromagnetic connection portion 2201 may be disposed in the same layer; and the second electromagnetic electrode 222 and the second electromagnetic connection portion 2202 may be disposed in the same layer.

[0035] Combination Figure 2 and Figure 5 As shown, Figure 5 for Figure 2A top view of the first touch metal layer TM1, wherein the first electromagnetic electrode 221 and the first electromagnetic connection portion 2201 can be disposed in the same layer on the first touch metal layer TM1.

[0036] Combination Figure 2 and Figure 6 As shown, Figure 6 for Figure 2 A top view of the second touch metal layer TM2, wherein the second electromagnetic electrode 222 and the second electromagnetic connection portion 2202 can be disposed in the same layer as the second touch metal layer TM2.

[0037] It should be noted that when the first electromagnetic electrode 221 and the first electromagnetic connection portion 2201 are arranged on the same layer, they can be regarded as two parts located in different regions of a whole, that is, there is no interface between them. When the second electromagnetic electrode 222 and the second electromagnetic connection portion 2202 are arranged on the same layer, they can be regarded as two parts located in different regions of a whole, that is, there is no interface between them.

[0038] When the touch layer 2 is set to include, for example Figure 3 and Figure 4 When the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3 are shown, optionally, in this embodiment of the invention, the first touch metal layer TM1 may include one of the first electromagnetic electrode 221 and the second electromagnetic electrode 222; and the second touch metal layer TM2 may include the other of the first electromagnetic electrode 221 and the second electromagnetic electrode 222 and the second capacitor connection portion 2132. Figure 2 and Figure 5 The first touch metal layer TM1 includes a first electromagnetic electrode 221 and a first electromagnetic connection portion 2201. Figure 2 and Figure 6 The second touch metal layer TM2 includes a second electromagnetic electrode 222, a second electromagnetic connection portion 2202, and a second capacitor connection portion 2132 as an example.

[0039] Combination Figure 2 and Figure 7 As shown, Figure 7 for Figure 2 A top view of the third touch metal layer in the present invention. In this embodiment, the third touch metal layer TM3 may include a first capacitor electrode 211, a first capacitor connection portion 2131, and a second capacitor electrode 212.

[0040] In another implementation, the second electromagnetic electrode 222 and the second electromagnetic connection portion 2202 may be disposed in different layers, while the first electromagnetic electrode 221, the first electromagnetic connection portion 2201 and the second electromagnetic electrode 222 may be disposed in the same layer.

[0041] Combination Figure 8, Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, Figure 8 for Figure 1 Another enlarged schematic diagram of region A1 in the middle. Figure 9 for Figure 8 A top view of the first touch-sensitive metal layer. Figure 10 for Figure 8 A top view of the second touch-sensitive metal layer. Figure 11 for Figure 8 A top view of the third touch-sensitive metal layer. Figure 12 for Figure 8 A cross-sectional schematic diagram along DD' shows that the first touch metal layer TM1 includes a first electromagnetic electrode 221, a first electromagnetic connection portion 2201, and a second electromagnetic electrode 222; the second touch metal layer TM2 includes a second capacitor connection portion 2132 and a second electromagnetic connection portion 2202; and the third touch metal layer TM3 includes a first capacitor electrode 211, a second capacitor electrode 212, and a first capacitor connection portion 2131.

[0042] Combination Figure 8 and Figure 13 As shown, Figure 13 for Figure 8 A cross-sectional schematic diagram along EE' shows that the first touch insulating layer TS1 includes a first via H1, and the second electromagnetic connection portion 2202 located in the second touch metal layer TM2 is electrically connected to the second electromagnetic electrode 222 located in the first touch metal layer TM1 through the first via H1.

[0043] In another optional embodiment, the present invention may allow the first electromagnetic electrode 221 to include a first structure and a second structure stacked and electrically connected; and / or allow the second electromagnetic electrode 222 to also include a first structure and a second structure stacked and electrically connected. The first structure and the second structure in the first electromagnetic electrode are essentially connected in parallel, which can reduce the resistance of the first electromagnetic electrode 221. The first structure and the second structure in the second electromagnetic electrode 222 are essentially connected in parallel, which can reduce the resistance of the second electromagnetic electrode 222.

[0044] For example, one of the first structure and the second structure is disposed on the same layer as the first electromagnetic connection portion 2201; the other of the first structure and the second structure is disposed on the same layer as the second electromagnetic connection portion 2202.

[0045] For example, such as Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, Figure 14 for Figure 1 Another enlarged schematic diagram of the central region A1. Figure 15 for Figure 14 A top view of the first touch-sensitive metal layer. Figure 16 for Figure 14 A top view of the second touch-sensitive metal layer. Figure 17 for Figure 14 A top view of the third touch-sensitive metal layer. Figure 18 for Figure 14 A schematic diagram of a cross-section along FF'. Figure 19 for Figure 14 A schematic diagram of a cross-section along GG'. Figure 15 The first structure 201_1 of the first electromagnetic electrode 221, the first structure 201_2 of the second electromagnetic electrode 222, and the first electromagnetic connection portion 2201 are disposed on the same layer of the first touch metal layer TM1. Figure 16 The second structure 202_1 of the first electromagnetic electrode 221, the second structure 202_2 of the second electromagnetic electrode 222, and the second electromagnetic connection part 2202 are disposed in the same layer on the second touch metal layer TM2 as an illustration.

[0046] like Figure 18 and Figure 19 As shown, the display panel also includes a first insulating layer 231 located between the first structure 201 and the second structure 202, the first insulating layer 231 including a via 200.

[0047] It should be noted that when the first structure 201 is located in the first touch insulating layer TS1 and the second structure 202 is located in the second touch insulating layer TS2, the first insulating layer 231 is the first touch insulating layer TS1.

[0048] like Figure 18 As shown, the first structure 201_1 and the second structure 202_1 in the first electromagnetic electrode 221 are electrically connected through at least two vias 200. Figure 19 As shown, the first structure 201_2 and the second structure 202_2 in the second electromagnetic electrode 222 are electrically connected through at least two vias 200.

[0049] In an embodiment of the present invention, the first touch metal layer TM1 or the second touch metal layer TM2 includes a second capacitor connection portion 2132; Figure 14 and Figure 16 The second touch metal layer TM2 includes a second capacitor connection portion 2132 as an example.

[0050] like Figure 17 As shown, the third touch metal layer TM3 includes a first capacitor electrode 211, a second capacitor electrode 212, and a first capacitor connection portion 2131.

[0051] For example, an organic insulating layer is included between any two adjacent elements of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3. That is, Figure 3 , Figure 4 , Figure 12 , Figure 13 , Figure 18 and Figure 19 The first touch insulating layer TS1 and the second touch insulating layer TS2 are organic insulating layers containing organic materials. Compared with inorganic materials, organic materials have good bending performance. Therefore, based on this arrangement, the bending performance of the display panel can be improved, and the bending reliability of the display panel can be improved when it is used in a foldable display device.

[0052] For example, the organic insulating layer includes any one or more of polyethersulfone (PES), polyacrylate, polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate (PAR), polyimide (PI), polycarbonate (PC), and cellulose acetate propionate (CAP).

[0053] It should be noted that, Figure 3 , Figure 4 , Figure 12 , Figure 13 , Figure 18 and Figure 19 The arrangement of the first touch metal layer TM1, the second touch metal layer TM2, and the third touch metal layer TM3 from bottom to top is only an illustration. Their order can be changed according to different design requirements, and the embodiments of the present invention do not limit this.

[0054] Optional, such as Figure 20 As shown, Figure 20 This is a top view schematic diagram of another display panel provided in an embodiment of the present invention. The display panel further includes a display area AA and a non-display area NA; the display area includes multiple sub-pixels ( Figure 1 (not shown), so that the display area AA can display the image.

[0055] In this embodiment of the invention, at least a portion of the first capacitor electrode, the second capacitor electrode, the first electromagnetic electrode, and the second electromagnetic electrode are located in the display area AA. To more clearly illustrate the first electromagnetic electrode 221 and the second electromagnetic electrode 222, in... Figure 20 The first and second capacitor electrodes are omitted.

[0056] like Figure 20As shown, the non-display area NA includes a third electromagnetic electrode 223 and a fourth electromagnetic electrode 224. The third electromagnetic electrode 223 is electrically connected to one end of at least two first electromagnetic electrodes 221; the fourth electromagnetic electrode 224 is electrically connected to one end of at least two second electromagnetic electrodes 222. Figure 20 The diagram illustrates a scenario where the third electromagnetic electrode 223 is electrically connected to one end of the two first electromagnetic electrodes 221, and the fourth electromagnetic electrode 224 is electrically connected to one end of the two second electromagnetic electrodes 222.

[0057] When the electromagnetic touch unit is working, the third electromagnetic electrode 223 connects to the two first electromagnetic electrodes 221 to form a first electromagnetic coil, in which current can flow to form a circuit. Figure 20 The first arrow X1 indicates the direction of current flow in one of the first electromagnetic coils; the fourth electromagnetic electrode 224 connects to the two second electromagnetic electrodes 222 to form a second electromagnetic coil; current can flow in the second electromagnetic coil to form a loop; Figure 20 The direction of current flow in one of the second electromagnetic coils is indicated by the second arrow X2.

[0058] For example, such as Figure 21 As shown, Figure 21 This is a top view schematic diagram of another display panel provided in an embodiment of the present invention. The display panel further includes an electromagnetic control circuit 3. The electromagnetic control circuit 3 is electrically connected to the other end of the first electromagnetic electrode 221 or the other end of the second electromagnetic electrode 222. The other end of the first electromagnetic electrode 221 refers to the end of the first electromagnetic electrode 221 that is not connected to the third electromagnetic electrode 223. The other end of the second electromagnetic electrode 222 refers to the end of the second electromagnetic electrode 222 that is not connected to the fourth electromagnetic electrode 224.

[0059] For example, such as Figure 21 As shown, the electromagnetic control circuit 3 includes a first switch 311, an electromagnetic drive module 32, and an electromagnetic induction module 33. In this embodiment of the invention, the electromagnetic touch process of the display panel includes an electromagnetic driving stage and an electromagnetic induction stage. In the electromagnetic driving stage, such as... Figure 21 As shown, the first switch 311 is electrically connected to the electromagnetic drive module 32 and the aforementioned first electromagnetic electrode 221 or second electromagnetic electrode 222. The electromagnetic drive signal generated by the electromagnetic drive module 32 can be transmitted in a first electromagnetic coil formed by the third electromagnetic electrode 223 and the two first electromagnetic electrodes 221, or in a second electromagnetic coil formed by the fourth electromagnetic electrode 224 and the two second electromagnetic electrodes 222. The electromagnetic drive signal includes alternating current, the frequency of which can correspond to the resonant frequency of the stylus. When the stylus touches the display panel, the oscillation circuit within the stylus senses the change in the magnetic field and generates a feedback signal with a specific frequency.

[0060] In the electromagnetic induction stage, such as Figure 22 As shown, Figure 22 for Figure 21 The diagram shown illustrates the display panel in the electromagnetic induction phase, with the first switch 311... Figure 21 The state shown switches to an electrical connection between the electromagnetic induction module 33 and the aforementioned first electromagnetic electrode 221 or second electromagnetic electrode 222. The electrical signal within the first electromagnetic coil formed by the third electromagnetic electrode 223 and the two first electromagnetic electrodes 221 can be transmitted to the electromagnetic induction module 33; alternatively, the electrical signal within the second electromagnetic coil formed by the fourth electromagnetic electrode 224 and the two second electromagnetic electrodes 222 can be transmitted to the electromagnetic induction module 33. The electromagnetic induction module 33 can receive signals of a specific frequency emitted by the aforementioned first or second electromagnetic coil and calculate the coordinates of the stylus based on the electromagnetic signal quantity of different channels. Specifically, the first electromagnetic coil formed with the participation of the first electromagnetic electrode 221 can be used to locate the stylus's coordinates in the first direction h11, and the second electromagnetic coil formed with the participation of the second electromagnetic electrode 222 can be used to locate the stylus's coordinates in the second direction h12.

[0061] For example, such as Figure 20 , Figure 21 and Figure 22 As shown, in this embodiment of the invention, two adjacent second electromagnetic electrodes 222 on the first direction h11 can form a second electromagnetic coil, and two adjacent first electromagnetic electrodes 221 on the second direction h12 can form a first electromagnetic coil.

[0062] For example, such as Figure 21 and Figure 22 As shown, the electromagnetic control circuit 3 also includes a second switch 312. Of the two second electromagnetic electrodes 222 forming the second electromagnetic coil, one end of the second electromagnetic electrode 222 that is not connected to the fourth electromagnetic electrode 224 is connected to the first switch 311 via the second switch 312. The other end of the second electromagnetic electrode 222 that is not connected to the fourth electromagnetic electrode 224 can be connected to the fixed signal terminal VSS. Current can flow between the second electromagnetic electrode 222 and the fourth electromagnetic electrode 224 connected to the electromagnetic drive module 32 or the electromagnetic induction module 33, and between the second electromagnetic electrode 222 connected to the fixed signal terminal VSS and the fixed signal terminal VSS, forming a loop.

[0063] When the display panel is electromagnetically touched, the second switch 312 can switch between different second electromagnetic electrodes 222 that are not connected to the fixed signal terminal VSS, so that the electromagnetic drive module 32 can charge different second electromagnetic coils, or transmit electrical signals from different second electromagnetic coils to the electromagnetic induction module 33.

[0064] For example, such as Figure 21 and Figure 22 As shown, in the two first electromagnetic electrodes constituting the first electromagnetic coil, one end of the first electromagnetic electrode 221 that is not connected to the third electromagnetic electrode 223 can be connected to the first switch 311 via the second switch 312, and the other end of the first electromagnetic electrode 221 that is not connected to the third electromagnetic electrode 223 can be connected to the fixed signal terminal VSS. Current can flow between the first electromagnetic electrode 221 and the third electromagnetic electrode 223 connected to the electromagnetic drive module 32 or the electromagnetic induction module 33, and between the first electromagnetic electrode 221 connected to the fixed signal terminal VSS and the fixed signal terminal VSS to form a loop.

[0065] When the display panel is electromagnetically touched, the second switch 312 can switch between different first electromagnetic electrodes 221 that are not connected to the fixed signal terminal VSS, so that the electromagnetic drive module 32 can charge different first electromagnetic coils, or transmit electrical signals from different first electromagnetic coils to the electromagnetic induction module 33.

[0066] Figure 21 and Figure 22 The electromagnetic drive module 32 is electrically connected to the second electromagnetic electrode 222 via the first switch 311 and the second switch 312 as an illustration. The case where the second switch 312 is connected to the first electromagnetic electrode 221 is similar, and will not be illustrated in the attached figure.

[0067] In another alternative embodiment, the present invention may also electrically connect the third electromagnetic electrode 223 to at least three first electromagnetic electrodes 221, and the fourth electromagnetic electrode 224 to at least three second electromagnetic electrodes 222. For example... Figure 23 As shown, Figure 23 This is a schematic diagram of yet another display panel provided in an embodiment of the present invention. Figure 23 The third electromagnetic electrode 223 is electrically connected to eight first electromagnetic electrodes, which are labeled as 221_1, 221_2, ..., 221_7, 221_8 respectively. The fourth electromagnetic electrode 224 is connected to fourteen second electromagnetic electrodes, which are labeled as 222_1, 222_2, ..., 222_13, 222_14 respectively for illustration.

[0068] like Figure 23As shown, in addition to the first switch 311 and the second switch 312, the electromagnetic control circuit 3 also includes a third switch 313. One of the first electromagnetic electrodes forming the first electromagnetic coil is electrically connected to the first switch 311 via the second switch 312, and the other first electromagnetic electrode is electrically connected to the reference potential terminal 34 in the electromagnetic control module 3 via the third switch 313. One of the second electromagnetic electrodes 222 forming the second electromagnetic coil is electrically connected to the first switch 311 via the second switch 312, and the other second electromagnetic electrode 222 is electrically connected to the reference potential terminal 34 via the third switch 313.

[0069] based on Figure 23 The setup shown allows for the adjustment of the size and position of the first or second electromagnetic coil by controlling the selection of different first electromagnetic electrodes 221 or second electromagnetic electrodes 222 through the second switch 312 and the third switch 313, thereby improving the flexibility of the electromagnetic coil.

[0070] For example, when it is necessary for the second electromagnetic electrode 222_7 and the second electromagnetic electrode 222_8 to form a second electromagnetic coil, the second switch 312 is controlled to electrically connect the second electromagnetic electrode 222_7, and the third switch 313 is controlled to electrically connect the second electromagnetic electrode 222_8. When it is necessary for the second electromagnetic electrode 222_8 and the second electromagnetic electrode 222_9 to form a second electromagnetic coil, this can be achieved by controlling the second switch 312 to electrically connect the second electromagnetic electrode 222_8, and controlling the third switch 313 to electrically connect the second electromagnetic electrode 222_9, which is simple to operate.

[0071] In addition, in comparison Figure 23 and Figure 20 It can be seen that, Figure 20 The display panel shown has seven first electromagnetic coils formed by fourteen first electromagnetic electrodes (the fourteen first electromagnetic electrodes are labeled as 221_1, 221_2, ..., 221_13, 221_14 respectively), and thirteen second electromagnetic coils formed by twenty-six second electromagnetic electrodes (the twenty-six second electromagnetic electrodes are labeled as 222_1, 222_2, ..., 222_25, 222_26 respectively).

[0072] exist Figure 23 In the display panel shown, taking the first electromagnetic coil formed by any two adjacent first electromagnetic electrodes 221 as an example, Figure 23The display panel shown has seven first electromagnetic coils formed by eight first electromagnetic electrodes 221. These seven first electromagnetic coils are formed by first electromagnetic electrodes 221_1 and 221_2, first electromagnetic electrodes 221_2 and 221_3, first electromagnetic electrodes 221_3 and 221_4, ..., first electromagnetic electrodes 221_6 and 221_7, and first electromagnetic electrodes 221_7 and 221_8.

[0073] It can be seen that, using Figure 23 As shown, since the third electromagnetic electrode 223 can participate in forming the first electromagnetic coil formed by different first electromagnetic electrodes 221 at different times, when the number of first electromagnetic coils formed is the same, by selecting different first electromagnetic electrodes 221 through the second switch 312 and the third switch 313, the required number of first electromagnetic electrodes 221 can be reduced. This, in turn, reduces the number of first traces 41 electrically connected to the first electromagnetic electrodes 221, which is beneficial for reducing the width of the non-display area NA where the first traces 41 are located. In other words, when the number of first electromagnetic electrodes 221 is fixed, based on... Figure 23 The method shown, in which the third electromagnetic electrode 223 is electrically connected to at least three first electromagnetic electrodes 221, can increase the number of first electromagnetic coils formed and improve the reliability of electromagnetic touch control.

[0074] Furthermore, taking the second electromagnetic coil formed by any two adjacent second electromagnetic electrodes 222 as an example, Figure 23 The display panel shown has thirteen second electromagnetic coils formed by fourteen second electromagnetic electrodes 222. These thirteen second electromagnetic coils are formed by second electromagnetic electrodes 222_1 and 222_2, second electromagnetic electrodes 222_2 and 222_3, second electromagnetic electrodes 222_3 and 222_4, ..., second electromagnetic electrodes 222_12 and 222_13, and second electromagnetic electrodes 222_13 and 222_14.

[0075] As can be seen, embodiments of the present invention can electrically connect at least three second electromagnetic electrodes 222 to the fourth electromagnetic electrode 224, employing... Figure 23As shown, since the fourth electromagnetic electrode 224 can participate in forming the second electromagnetic coil formed by different second electromagnetic electrodes 222 at different times, when the number of second electromagnetic coils formed is the same, by selecting different second electromagnetic electrodes 222 through the second switch 312 and the third switch 313, the required number of second electromagnetic electrodes 222 can be reduced. This, in turn, reduces the number of second traces 42 electrically connected to the second electromagnetic electrodes 222, which is beneficial for reducing the width of the non-display area NA where the second traces 42 are located. In other words, when the number of second electromagnetic electrodes 222 is fixed, based on... Figure 23 The method shown, in which the fourth electromagnetic electrode 224 is electrically connected to at least three second electromagnetic electrodes 222, can increase the number of second electromagnetic coils formed and improve the reliability of electromagnetic touch control.

[0076] For example, such as Figure 20 , Figure 21 , Figure 22 and Figure 23 As shown, the non-display area NA also includes multiple first traces 41 and second traces 42. The first traces 41 are electrically connected to the first electromagnetic electrode 221, and the second traces 42 are electrically connected to the second electromagnetic electrode 222.

[0077] like Figure 20 , Figure 21 , Figure 22 and Figure 23 As shown, the non-display area NA includes a bonding area BA. Optionally, the bonding area BA may be located on one side of the display area AA in the second direction h12. For example, the bonding area BA may include multiple pads ( Figure 20 , Figure 21 , Figure 22 and Figure 23 (Not shown), the first trace 41 and the second trace 42 can extend to the bonding area BA and be bonded to the corresponding pads. The second switch 312 and the third switch 313 can be electrically connected to the first electromagnetic electrode 221 or the second electromagnetic electrode 222 through the corresponding pads.

[0078] Optionally, the electromagnetic control circuit 3 described above can be integrated into the driver chip, and the driver chip can be bonded to the pads.

[0079] For example, such as Figure 20 , Figure 21 , Figure 22 and Figure 23 As shown, in this embodiment of the invention, the first trace 41 and the third electromagnetic electrode 223 can be located on both sides of the display area AA.

[0080] Or, such as Figure 24 As shown, Figure 24This is a schematic diagram of another display panel provided by an embodiment of the present invention. In this embodiment, the aforementioned plurality of first traces 41 can be divided into two parts. Along the first direction h11, at least a portion of one part of the first traces 41 is located on one side of the display area AA, and at least a portion of the other part of the first traces 41 is located on the other side of the display area AA. Based on this arrangement, the width of the non-display area NA located on both sides of the display area AA can be balanced, avoiding excessive width of the non-display area NA located on one side of the display area AA.

[0081] For example, such as Figure 24 As shown, the third electromagnetic electrode 223 includes a first sub-electromagnetic electrode 2231 and a second sub-electromagnetic electrode 2232. The first sub-electromagnetic electrode 2231 is electrically connected to a portion of the first electromagnetic electrode 221, and the second sub-electromagnetic electrode 2232 is electrically connected to another portion of the first electromagnetic electrode 221. For example, the number of first electromagnetic electrodes 221 electrically connected to the first sub-electromagnetic electrode 2231 and the second sub-electromagnetic electrode 2232 can both be greater than 2.

[0082] Along the first direction h11, the first sub-electromagnetic electrode 2231 and the second sub-electromagnetic electrode 2232 are located on both sides of the display area AA to balance the width of the non-display area NA on both sides of the display area AA and avoid the non-display area NA on one side of the display area AA from being too wide.

[0083] It should be noted that, in order to more clearly show the first electromagnetic electrode 221 and the second electromagnetic electrode 222, in Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 24 The first and second capacitor electrodes are omitted.

[0084] like Figure 21 , Figure 22 , Figure 23 and Figure 24 As shown, along the second direction h12, the electromagnetic control circuit 3 is located on one side of the display area AA, and the fourth electromagnetic electrode 224 is located on the side of the display area AA away from the electromagnetic control circuit 3. By respectively placing the fourth electromagnetic electrode 224 and the electromagnetic control circuit 3 on opposite sides of the display area AA along the second direction h12, this embodiment of the invention avoids the problem of excessively wide single-sided bezels on the display panel caused by the fourth electromagnetic electrode 224 and the electromagnetic control circuit 3 being concentrated on the same side of the display area AA.

[0085] For example, such as Figure 25 As shown, Figure 25This is a schematic diagram of another display panel provided in an embodiment of the present invention. The display panel further includes a plurality of fourth switches 314 and a plurality of fifth switches 315. The first and second poles of the fourth switches 314 are electrically connected to the first electromagnetic electrode 221 and the third electromagnetic electrode 223, respectively. The first and second poles of the fifth switches 315 are electrically connected to the second electromagnetic electrode 222 and the fourth electromagnetic electrode 224, respectively. The control poles of the fourth switches 314 and the fifth switches 315 can receive touch mode control signals.

[0086] In this embodiment of the invention, the touch process of the display panel includes an electromagnetic touch stage and a capacitive touch stage; in the electromagnetic touch stage, the touch mode control signal can control at least two fourth switches 314 to be turned on, and the first electromagnetic electrode 221 and the third electromagnetic electrode 223 electrically connected to the at least two fourth switches 314 form a first electromagnetic coil; or, the touch mode control signal can control at least two fifth switches 315 to be turned on, and the second electromagnetic electrode 222 and the fourth electromagnetic electrode 224 electrically connected to the at least two fifth switches 315 form a second electromagnetic coil; During the capacitive touch phase, the aforementioned touch mode control signal can control the fourth switch 314 to open and the fifth switch 315 to open. The first electromagnetic electrode 221 is reused as the first capacitor electrode 211, and the second electromagnetic electrode 222 is reused as the second capacitor electrode 212. Based on this configuration, only one electrode structure needs to be provided in the display panel to enable the display panel to support both finger touch and stylus touch, simplifying the structure of the display panel.

[0087] For example, such as Figure 26 As shown, Figure 26 This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. In this embodiment, the display film layer 30 includes a pixel definition layer 5, which is located on the side of the touch layer 2 near the substrate 1. The pixel definition layer 5 includes a plurality of pixel openings 50. At least one of the first capacitor electrode, the second capacitor electrode, the first capacitor connection portion, the second capacitor connection portion, the first electromagnetic electrode, the second electromagnetic electrode, the first electromagnetic connection portion, and the second electromagnetic connection portion includes a grid opening 20. Along the direction h2 perpendicular to the plane where the substrate 1 is located, the grid opening 20 and the pixel openings 50 at least partially overlap.

[0088] like Figure 26 As shown, the display panel also includes a sub-pixel 3, which includes a first electrode 31, a second electrode 32, and a light-emitting layer 33. At least a portion of the light-emitting layer 33 is located within a pixel opening 50. The orthographic projections of the first metal line 201 and the second metal line 202 onto the plane of the substrate 1 are located between two adjacent pixel openings 50. Optionally, the sub-pixel 3 includes an organic light-emitting diode or an inorganic light-emitting diode.

[0089] Combination Figure 27 and Figure 28 As shown, Figure 27 This is a schematic diagram of an electromagnetic touch unit provided in an embodiment of the present invention. Figure 28 for Figure 27 An enlarged schematic diagram of region A2 shows that, in this embodiment of the invention, at least one of the first capacitor electrode 211, the second capacitor electrode 212, the first capacitor connection portion 2131, the second capacitor connection portion 2132, the first electromagnetic electrode 221, the second electromagnetic electrode 222, the first electromagnetic connection portion 2201, and the second electromagnetic connection portion 2202 includes a first metal line 201 and a second metal line 202 that intersect in their extending directions and are electrically connected; the first metal line 201 and the second metal line 202 intersect to form the aforementioned grid opening 20. The first metal line 201 and the second metal line 202 are arranged to avoid the pixel opening 50, that is, the orthographic projection of the pixel opening 50 on the plane of the substrate 1 and the orthographic projection of the first metal line 201 on the plane of the substrate 1 do not overlap, and the orthographic projection of the pixel opening 50 on the plane of the substrate 1 and the orthographic projection of the second metal line 202 on the plane of the substrate 1 do not overlap. Based on this arrangement, the first metal line 201 and the second metal line 202 can be prevented from affecting the light emission of the sub-pixels located within the pixel opening 50, thus ensuring the display effect of the display panel. For example, the line width of the first metal line 201 and the second metal line 202 is smaller than the spacing between two adjacent pixel openings 50, and the orthographic projection of the first metal line 201 and the second metal line 202 on the plane of the substrate 1 can be located between two adjacent pixel openings 50 respectively.

[0090] The cross arrangement of the first metal line 201 and the second metal line 202 is equivalent to connecting multiple first metal lines 201 in parallel, and connecting multiple second metal lines 202 in parallel. This increases the conduction path of the touch signal in the first capacitor electrode 211, the second capacitor electrode 212, the first capacitor connection 2131, the second capacitor connection 2132, the first electromagnetic electrode 221, the second electromagnetic electrode 222, the first electromagnetic connection 2201, and the second electromagnetic connection 2202. This reduces the resistance of the first capacitor electrode 211, the second capacitor electrode 212, the first capacitor connection 2131, the second capacitor connection 2132, the first electromagnetic electrode 221, the second electromagnetic electrode 222, the first electromagnetic connection 2201, and the second electromagnetic connection 2202. This reduces the delay of the touch signal during touch operation and improves the touch effect of the display panel.

[0091] It should be noted that, Figure 28 The first electromagnetic connection part 2201 is a linear structure, which is only for illustration. In this embodiment of the invention, the first electromagnetic connection part 2201 can also be a structure including a grid opening 20, which will not be shown in the figure here.

[0092] It should be noted that, Figure 28 The arrangement of the pixel openings 50 in the diagram is merely illustrative and is not intended to limit the scope of the invention. For example, as... Figure 29 As shown, Figure 29 This is a schematic diagram of a first electromagnetic electrode and a pixel opening provided in an embodiment of the present invention. The first metal line 201 constituting the first electromagnetic electrode 221 extends along a first direction h11, and the second metal line 202 constituting the first electromagnetic electrode 221 extends along a second direction h12. The pixel opening 50 may include a first pixel opening 501, a second pixel opening 502, and a third pixel opening 503. Along the second direction h12, the first pixel opening 501 and the second pixel opening 502 are alternately arranged in a first column L1, and multiple third pixel openings 503 can be arranged in a second column L2. The first column L1 and the second column L2 can be alternately arranged in the first direction h11.

[0093] For example, Figure 20 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 The third electromagnetic electrode 223 and the fourth electromagnetic electrode 224 shown can be configured to have a structure without grid openings. In the non-display area NA where the third electromagnetic electrode 223 and the fourth electromagnetic electrode 224 are located, there is no need to set sub-pixels. Therefore, by configuring the third electromagnetic electrode 223 and the fourth electromagnetic electrode 224 to have a structure without grid openings, this embodiment of the invention is beneficial to increase the width of the third electromagnetic electrode 223 and the fourth electromagnetic electrode 224, thereby reducing the resistance of the third electromagnetic electrode 223 and the fourth electromagnetic electrode 224.

[0094] Based on the same inventive concept, embodiments of the present invention also provide a display device, such as... Figure 30 As shown, Figure 30 This is a schematic diagram of a display device provided in an embodiment of the present invention. The display device includes the display panel 100 described above. The specific structure of the display panel 100 has been described in detail in the above embodiments and will not be repeated here. Of course, Figure 30 The display device shown is for illustrative purposes only. The display device can be any electronic device with display function, such as a mobile phone, in-vehicle display, tablet computer, laptop computer, e-reader or television.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
