Description

[0002] With the development of big data on the Internet, technologies related to human-computer interaction have become increasingly important. Touch technology is undoubtedly the most basic interaction technology. However, current electromagnetic touch technology (EMR) is mostly external electromagnetic touch modules, that is, electromagnetic touch modules are superimposed on the display panel.

[0003] During research and practice in the field, the inventors discovered that when integrating electromagnetic touch control into a display panel, the shared metal layer for the electromagnetic touch control and the display traces can interfere with each other. For example, in a MiniLED (Light-emitting diode) display panel, the connection line between two adjacent MiniLEDs inevitably creates overlapping capacitance with the electromagnetic touch coil. This causes the current flowing through the connection line to be periodically disturbed by the electromagnetic touch coil's transmitted or received signals. Summary of the Invention

[0049] The technical solutions 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 only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.

[0050] The embodiments of the present application provide a display panel and an electronic device. Detailed descriptions are provided below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments.

[0051] See also Figure 1-Figure 3 The present embodiment provides a display panel 100, comprising a substrate 110, a plurality of first touch coils 120, and a plurality of second touch coils 130. The first touch coils 120 and the second touch coils 130 are disposed on the substrate 110, and the first touch coils 120 and the second touch coils 130 are located in different structural layers and are insulated from each other. In the present embodiment, the first touch coils 120 and the second touch coils 130 are electromagnetic touch coils.

[0052] A plurality of first touch coils 120 are spaced apart along a first direction X, and the first touch coils 120 are configured to sense touch signals in a second direction Y. A plurality of second touch coils 130 are spaced apart along the second direction Y, and the second touch coils 130 are configured to sense touch signals in the first direction X. The first direction X and the second direction Y intersect, and the angle between the first direction X and the second direction Y can be, but is not limited to, a perpendicular angle.

[0053] In this structure, the first touch coil 120 senses touch signals in the second direction Y, thereby detecting the coordinates of the touch point in the second direction Y. The second touch coil 130 senses touch signals in the first direction X, thereby detecting the coordinates of the touch point in the first direction X. This allows the specific location of the touch point to be determined. In this embodiment, the display panel 100 further includes a control chip 190. The pins at both ends of the first touch coil 120 are connected to the control chip 190, and the pins at both ends of the second touch coil 130 are connected to the control chip 190.

[0054] Specifically, such as Figure 1As shown, the display panel 100 further includes a plurality of pad groups 140 and a plurality of light-emitting devices 150. The light-emitting devices 150 may be, but are not limited to, Mini LEDs (Light-emitting diodes). The pad groups 140 are disposed on the substrate 110, and the light-emitting devices 150 may be, but are not limited to, disposed on the corresponding pad groups 140 through a welding process. The plurality of pad groups 140 are arranged in an array in a multi-row × multi-column manner. The pad groups 140 are disposed on the side of the first touch coil 120 facing away from the substrate 110, and the pad groups 140 are insulated from the first touch coil 120. The projections of the pad groups 140 and the first touch coil 120 on the substrate 110 do not overlap. In this embodiment, the row direction of the pad groups 140 is the first direction X, and the column direction of the pad groups 140 is the second direction Y.

[0055] Specifically, such as Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the display panel 100 further includes a plurality of connecting wires 160. The connecting wires 160 are disposed on the substrate 110. The connecting wires 160 are disposed in a different layer from the first touch coil 120 and are insulated from the second touch coil 130. The connecting wires 160 are connected to two pad groups 140, such that the two pad groups 140 are connected in series via the connecting wires 160. The connecting wires 160 and the first touch coil 120 are located in different structural layers and are disposed in a different layer. The connecting wires 160 intersect with the first touch coil 120, forming an overlapping region 170 at the intersection. In this embodiment, the thickness direction refers to the third direction Z. Any two of the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other.

[0056] Specifically, such as Figure 4-Figure 6 As shown, a recessed portion 161 is defined on the surface of the connecting wire 160 near the first touch coil 120. The recessed portion 161 extends from the connecting wire 160 toward a direction away from the first touch coil 120. The recessed portion 161 corresponds to the overlapping region 170. It should be noted that to illustrate the recessed portion 161 of the connecting wire 160, the first touch coil 120 is omitted, and its position is indicated by a dotted line.

[0057] In the embodiment of the present application, the overlapping region 170 includes an outer region 173 disposed on at least one side of the recessed portion 161 along the width direction of the first touch coil 120 . Along the width direction of the first touch coil 120 , the width of the outer region 173 and the width of the first touch coil 120 are related by:

[0058] 0≤D1<2;

[0059] D1 is the width of the outer region 173, and D2 is the width of the first touch coil 120. In this configuration, when the width D1 of all outer regions 173 is 0, no outer region 173 is defined in the overlapping region 170 along the width of the first touch coil 120.

[0060] In the embodiment of the present application, outer regions 173 are provided on opposite sides of the recessed portion 161 along the width direction of the first touch coil 120. The width D1 of all outer regions 173 is equal to the width D3 of one outer region 173 plus the width D4 of another outer region 173. Of course, depending on actual circumstances and specific requirements, the outer region 173 may be provided on only one side of the recessed portion 161 along the width direction of the first touch coil 120.

[0061] Figure 7 is a partial enlarged structural diagram of the display panel 100 provided in the comparative embodiment of the present application, Figure 8 It is along Figure 7 Schematic diagram of the cross-sectional structure in the CC direction. Figure 7 and Figure 8 The main difference between the display panel 100 shown and the display panel 100 of the embodiment of the present application is that the connecting line 160 of the embodiment of the present application has a recessed portion 161 in the overlapping area 170 . The connecting wire 160 and the first touch coil 120 have overlapping capacitance in the overlapping region 170 . Besides the dielectric constant of the insulating medium, the main factors determining the capacitance are the overlapping area and distance. When the depth of the recess 161 is less than the thickness of the connecting wire 160 , that is, when the recess 161 is a groove that does not penetrate the connecting wire 160 , the distance between the connecting wire 160 and the corresponding recess 161 of the first touch coil 120 can be increased, which helps reduce the overlapping capacitance between the connecting wire 160 and the first touch coil 120 . When the depth of the recess 161 is equal to the thickness of the connecting wire 160 , that is, when the recess 161 is a through hole that penetrates the connecting wire 160 , the overlapping area between the connecting wire 160 and the first touch coil 120 can be reduced, which helps reduce the overlapping capacitance between the connecting wire 160 and the first touch coil 120 . The above configuration can improve the technical problem of mutual interference between the connecting wires 160 and the electromagnetic touch coils in the display panel 100 , reduce the risk of defects when the electromagnetic touch design is integrated into the display panel 100 , and effectively improve the display stability of the display panel 100 .

[0062] Specifically, the cross-sectional area of ​​the recessed portion 161 accounts for 10% to 25% of the total cross-sectional area of ​​the overlapping region 170 . Within this range, the signal transmission capability of the connecting wire 160 can be guaranteed while effectively improving the mutual interference problem between the connecting wire 160 and the electromagnetic touch coil.

[0063] Specifically, such as Figure 1 and Figure 5 As shown, the display panel 100 further includes a plurality of first power branch lines VDD and second power branch lines VSS. The first touch coil 120 and the second touch coil 130 are both insulated from the first power branch line VDD, and the first touch coil 120 and the second touch coil 130 are both insulated from the second power branch line VSS. Of the two pad groups 140 connected to the same connection line 160, one pad group 140 is connected to the first power branch line VDD, and the other pad group 140 is connected to the second power branch line VSS.

[0064] Specifically, such as Figure 4-Figure 6 As shown, a recessed portion 161 is provided in the middle of the overlapping region 170 along the width of the connecting wire 160. The recessed portion 161 penetrates the surface of the connecting wire 160 to form a first opening 1611 located on the surface of the connecting wire 160. The surface of the connecting wire 160 includes at least the surface of the connecting wire 160 that is close to the first touch coil 120. When the recessed portion 161 is a groove, the surface of the connecting wire 160 only includes the surface of the connecting wire 160 that is close to the first touch coil 120, and the first opening 1611 of the recessed portion 161 is provided on the surface of the connecting wire 160 that is close to the first touch coil 120. When the recessed portion 161 is a through hole, the surface of the connecting wire 160 also includes the surface of the connecting wire 160 that is away from the first touch coil 120, and the first opening 1611 of the recessed portion 161 is provided on the surface of the connecting wire 160 that is away from the first touch coil 120.

[0065] Specifically, such as Figure 4-Figure 6 As shown, the overlapping area 170 includes a first area 171 and a second area 172. The second area 172 is located on opposite sides of the first area 171 along the width direction of the connecting line 160, that is, the first area 171 is located in the middle of the connecting line 160, and the second area 172 is located on both sides of the connecting line 160. Figure 5 and Figure 6 In the illustrated embodiment, the first region 171 is provided with a recessed portion 161, that is, the middle portion of the connecting line 160 is provided with a recessed portion 161. This structure helps alleviate the technical issue of interference between the connecting line 160 and the electromagnetic touch coil in the display panel 100. In the embodiment of the present application, the width direction of the connecting line 160 is the second direction Y, and the meaning of the width direction of the connecting line 160 will not be repeated hereafter.

[0066] Specifically, such as Figure 4 、 Figure 9 and Figure 10As shown, a recessed portion 161 is provided on at least one side of the overlapping region 170 along the width direction of the connecting wire 160. The recessed portion 161 penetrates the surface of the connecting wire 160 to form a first opening 1611 located on the surface of the connecting wire 160. The recessed portion 161 also penetrates the side of the connecting wire 160 to form a second opening 1612 located on the side of the connecting wire 160. The surface of the connecting wire 160 includes at least the side of the connecting wire 160 that is close to the first touch coil 120. When the recessed portion 161 is a groove, the surface of the connecting wire 160 only includes the side of the connecting wire 160 that is close to the first touch coil 120. The first opening 1611 of the recessed portion 161 is provided on the surface of the connecting wire 160 that is close to the first touch coil 120. When the recess 161 is a through hole, the surface of the connecting wire 160 also includes the surface of the connecting wire 160 away from the first touch coil 120 , and the surface of the connecting wire 160 away from the first touch coil 120 also defines the first opening 1611 of the recess 161 .

[0067] Specifically, such as Figure 4 、 Figure 9 and Figure 10 As shown, the overlapping area 170 includes a first area 171 and a second area 172. The second area 172 is located on opposite sides of the first area 171 along the width direction of the connecting line 160, that is, the first area 171 is located in the middle of the connecting line 160, and the second area 172 is located on both sides of the connecting line 160. Figure 9 and Figure 10 In the embodiment shown, the Figure 4 The second area 172 is provided with a recessed portion 161, and the recessed portion 161 includes a first opening 1611 and a second opening 1612. The first opening 1611 is provided on the surface of the connecting line 160 close to the first touch coil 120, and the second opening 1612 is provided on the side of the connecting line 160, that is, the recessed portion 161 is provided on at least one side of the connecting line 160 along the second direction Y.

[0068] It is understandable that the selection and setting according to actual conditions and specific needs, such as Figure 4As shown, both the first region 171 and the second region 172 are provided with a recessed portion 161. Specifically, the overlapping region 170 is provided with at least two recessed portions 161, one of which is located in the middle of the overlapping region 170 along the width direction of the connecting line 160, and the other recessed portion 161 is located on at least one side of the overlapping region 170 along the width direction of the connecting line 160. In the recessed portion 161 located in the middle of the overlapping region 170, the recessed portion 161 penetrates the surface of the connecting line 160 to form a first opening 1611 located on the surface of the connecting line 160. In the recessed portion 161 located on one side of the overlapping region 170, the recessed portion 161 penetrates the surface of the connecting line 160 to form the first opening 1611 located on the surface of the connecting line 160. The recessed portion 161 also penetrates the side of the connecting line 160 to form a second opening 1612 located on the side of the connecting line 160.

[0069] Specifically, in the embodiment of the present application, the display panel 100 includes a first metal layer M1, a first insulating layer IL1, a second metal layer M2, a second insulating layer IL2 and a third metal layer M3 stacked sequentially on the substrate 110, and the first touch coil 120 is disposed on the second metal layer M2. Figure 5 、 Figure 6 、 Figure 9 and Figure 10 In the embodiment shown, the connection line 160 is provided in the first metal layer M1. Of course, according to the actual situation and specific requirements, the connection line 160 can be provided in other structural layers, for example, Figure 11-14 As shown, the connecting wire 160 may also be provided on the third metal layer M3, which is not limited here. In the embodiment of the present application, the second touch coil 130 is provided on the third metal layer M3.

[0070] Figure 11 and Figure 12 The corresponding embodiments and Figure 5 and Figure 6 The difference between the corresponding embodiments is only that: Figure 5 and Figure 6 In the corresponding embodiment, the connecting line 160 is provided on the first metal layer M1; Figure 11 and Figure 12 In the corresponding embodiment, the connection line 160 is disposed in the third metal layer M3.

[0071] Figure 13 and Figure 14 The corresponding embodiments and Figure 9 and Figure 10 The difference between the corresponding embodiments is only that: Figure 9 and Figure 10 In the corresponding embodiment, the connecting line 160 is provided on the first metal layer M1; Figure 13 and Figure 14In the corresponding embodiment, the connection line 160 is disposed in the third metal layer M3.

[0072] Specifically, the thickness of the first insulating layer IL1 is less than the thickness of the second insulating layer IL2, which is beneficial to further reduce the overlap capacitance between the connecting line 160 and the first touch coil 120. In this structure, when the thickness of the first insulating layer IL1 is less than the thickness of the second insulating layer IL2, by disposing the connecting line 160 in the third metal layer M3, the distance between the connecting line 160 and the first touch coil 120 can be further increased, which is beneficial to reduce the overlap capacitance between the connecting line 160 and the first touch coil 120. For example, Figure 11 and Figure 12 The overlap capacitance of the corresponding embodiment is less than Figure 5 and Figure 6 The overlap capacitance of the corresponding embodiment, Figure 13 and Figure 14 The overlap capacitance of the corresponding embodiment is less than Figure 9 and Figure 10 The overlap capacitance of the corresponding embodiment.

[0073] Specifically, the thickness of the first insulating layer IL1 is 1000 angstroms to 2000 angstroms, and the thickness of the second insulating layer IL2 is 10,000 angstroms to 20,000 angstroms. Specifically, the thickness of the first insulating layer IL1 can be 1000 angstroms, 1100 angstroms, 1200 angstroms, 1300 angstroms, 1400 angstroms, 1500 angstroms, 1600 angstroms, 1700 angstroms, 1800 angstroms, 1900 angstroms, or 2000 angstroms, and the thickness of the second insulating layer IL2 can be 10,000 angstroms, 11,000 angstroms, 12,000 angstroms, 13,000 angstroms, 14,000 angstroms, 15,000 angstroms, 16,000 angstroms, 17,000 angstroms, 18,000 angstroms, 19,000 angstroms, or 20,000 angstroms. Of course, the thicknesses of the first insulating layer IL1 and the second insulating layer IL2 can be appropriately adjusted according to actual conditions and specific requirements, and are not limited here.

[0074] Specifically, the dielectric constant of the first insulating layer IL1 is smaller than the dielectric constant of the second insulating layer IL2 . In this structure, by disposing the connecting wire 160 in the third metal layer M3 , the overlap capacitance between the connecting wire 160 and the first touch coil 120 is reduced.

[0075] Specifically, in the embodiment of the present application, the recessed depth of the recessed portion 161 is equal to the thickness of the connecting line 160, that is, the recessed portion 161 is set to pass through the connecting line 160. Of course, according to the actual selection and specific needs, the recessed depth of the recessed portion 161 can also be less than the thickness of the connecting line 160, that is, the recessed portion 161 is a groove.

[0076] Specifically, such as Figure 1and Figure 15 As shown, the display panel 100 further includes a plurality of thin film transistors T, and the first power branch line VDD is connected to the pad group 140 through the corresponding thin film transistors T. The display panel 100 further includes a gate insulating layer GI, and the thin film transistor T includes an active layer AL, a gate Ge, a source electrode Se, and a drain electrode De. The active layer AL is provided on the substrate 110, and the gate Ge is provided on the active layer AL. The first insulating layer IL1 covers the gate Ge, the active layer AL, and the substrate 110. The source electrode Se and the drain electrode De are provided on the first insulating layer IL1, and the source electrode Se and the drain electrode De are respectively in contact with the active layer AL. The gate Ge is provided on the first metal layer M1, and the source electrode Se and the drain electrode De are provided on the second metal layer M2.

[0077] Specifically, such as Figure 16-Figure 19 As shown, in the overlapping region 170, the first touch coil 120 includes a first connecting portion 121 and a second connecting portion 122 connected to each other. The second connecting portion 122 is arranged corresponding to the recessed portion 161.
