[0022] The display panel 01 provided by the present application is arranged between two adjacent first electromagnetic touch control channels 21 adjacent to the first capacitive touch control channel 11. Therefore, in the direction perpendicular to the plane where the display panel 01 is located, the first electromagnetic touch control channel 21 does not overlap with the first capacitive touch control channel 11. The second capacitive touch control channel 12 is arranged between two adjacent second electromagnetic touch control channels 22. Therefore, in the direction perpendicular to the plane where the display panel 01 is located, the second electromagnetic touch control channel 22 does not overlap with the second capacitive touch control channel 12. Thereby, the capacitive touch control unit 10 and the electromagnetic touch control unit 20 share the space in the direction perpendicular to the plane where the display panel 01 is located, realizing the design of the structure in which both the capacitive touch control unit 10 and the electromagnetic touch control unit 20 are arranged in the touch control layer 03, and achieving the purpose of reducing the thickness of the display panel 01 and simplifying the production and manufacturing process.

[0023] In addition, the first capacitive touch control channel 11 is arranged insulated from the first electromagnetic touch control channel 21, and the second capacitive touch control channel 12 is arranged insulated from the second electromagnetic touch control channel 22. Thereby, the display panel 01 is provided with an electromagnetic touch function and a capacitive touch function, and the electromagnetic touch control signal and the capacitive touch control signal do not interfere with each other.

[0024] In some embodiments of the present application, the first direction X is the horizontal direction in FIG. 2, and the second direction Y is the vertical direction in FIG. 2. However, the present application does not limit the specific directions indicated by the first direction X and the second direction Y. For example, in other embodiments of the present application, the first direction X may be the vertical direction in FIG. 2, and the second direction Y may be the horizontal direction in FIG. 2.

[0025] In some embodiments of the present application, the first terminals 211 of every two of the first electromagnetic touch control channels 21 are electrically connected to form one first electromagnetic touch control channel group 40, and the first terminals 221 of every two of the second electromagnetic touch control channels 22 are electrically connected to form one second electromagnetic touch control channel group 50. Here, the two first electromagnetic touch control channels 21 in each first electromagnetic touch control channel group 40 are not adjacent, and the two second electromagnetic touch control channels 22 in each second electromagnetic touch control channel group 50 are not adjacent.

[0026] In the display panel 01 provided by the present application, the two first electromagnetic touch control channels 21 in each first electromagnetic touch control channel group 40 are not adjacent, and the two second electromagnetic touch control channels 22 in each second electromagnetic touch control channel group 50 are not adjacent. That is, at least one first electromagnetic touch control channel 21 in another first electromagnetic touch control channel group 40 is arranged between the two first electromagnetic touch control channels 21 in each first electromagnetic touch control channel group 40, and at least one second electromagnetic touch control channel 22 in another second electromagnetic touch control channel group 50 is arranged between the two second electromagnetic touch control channels 22 in each second electromagnetic touch control channel group 50.

As a result, the coil design for the electromagnetic coil is realized, and the electromagnetic driving function of the electromagnetic touch control unit 20 is greatly improved.

[0027] Furthermore, the first terminal 111 of the first capacitive touch control channel 11 is arranged insulated from the first electromagnetic touch control channel 21, and the first terminal 121 of the second capacitive touch control channel 12 is arranged insulated from the second electromagnetic touch control channel 22.

[0028] In some embodiments of the present application, the display panel 01 further includes a touch control drive chip 30, and the second terminal 112 of the first capacitive touch control channel 11, the second terminal 122 of the second capacitive touch control channel 12, the second terminal 212 of the first electromagnetic touch control channel 21, and the second terminal 222 of the second electromagnetic touch control channel 22 are all electrically connected to the touch control drive chip 30.

Thereby, the touch control accuracy of the electromagnetic touch control unit 20 can be greatly improved, and the quality of electromagnetic touch control can be improved.

[0032] Furthermore, the first capacitive touch control channel 11 located at the periphery of the display panel 01 is the first peripheral capacitive touch control channel 110, and two first electromagnetic touch control channels 21 are arranged on the side away from the other first capacitive touch control channels 11 of the first peripheral capacitive touch control channel 110.

The two second electromagnetic touch control channels 22 belong to different second electromagnetic touch control channel groups 50 respectively.

[0033] In the display panel 01 provided by the present application, two first electromagnetic touch control channels 21 are arranged on the side away from the other first capacitive touch control channels 11 of the first peripheral capacitive touch control channel 110, and the two first electromagnetic touch control channels 21 belong to different first electromagnetic touch control channel groups 40 respectively. Therefore, the first electromagnetic touch control channel group 40 located at the periphery of the display panel 01 can also realize the coil design with other first electromagnetic touch control channel groups 40.

[0034] Similarly, in the display panel 01 provided by the present application, on the side of the capacitive touch control channel 120 of the second periphery away from the other second capacitive touch control channels 12, two second electromagnetic touch control channels 22 are arranged. Since the two second electromagnetic touch control channels 22 belong to different second electromagnetic touch control channel groups 50 respectively, the second electromagnetic touch control channel group 50 located at the periphery of the display panel 01 can also realize the coil design with other second electromagnetic touch control channel groups 50.

[0035] FIG. 7 is a top schematic view showing the touch control electrode unit according to Embodiment 1 of the present application. Referring to FIGS. 1 to 7 together, in some embodiments of the present application, the first capacitive touch control channel 11 includes a plurality of first touch control electrodes 113 sequentially arranged along the second direction Y, and the second capacitive touch control channel 12 includes a plurality of second touch control electrodes 123 sequentially arranged along the first direction X. The adjacent first touch control electrode 113 and the second touch control electrode 123 constitute one touch control electrode unit TRD.

[0036] In the display panel 01 provided by the present application, in a manner that the touch control electrode unit TRD is surrounded by the first electromagnetic touch control channel 21 and the second electromagnetic touch control channel 22 arranged in an intersecting manner, in a direction perpendicular to the plane where the display panel 01 is located, the touch control electrode unit TRD is made not to overlap with the first electromagnetic touch control channel 21 and the second electromagnetic touch control channel 22, so as to realize the design of the structure in which both the capacitive touch control unit 10 and the electromagnetic touch control unit 20 are arranged in the touch control layer 03, and the purpose of reducing the thickness of the display panel 01 and simplifying the production and manufacturing process can be achieved.

[0037] Specifically, in a manner of reducing the area of the touch control electrode unit TRD, the touch control electrode unit TRD can be surrounded by the first electromagnetic touch control channel 21 and the second electromagnetic touch control channel 22 which are arranged in a crossed manner.

[0038] Furthermore, a dummy electrode B is arranged between the touch control electrode unit TRD and the first electromagnetic touch control channel 21 and the second electromagnetic touch control channel 22 which are arranged in a crossed manner, and the dummy electrode B is arranged in insulation from the touch control electrode unit TRD, the first electromagnetic touch control channel 21, and the second electromagnetic touch control channel 22 respectively.

[0039] In some embodiments of the present application, the first touch control electrode 113 includes one first main body portion 1131 and two first branch portions 1132. The first main body portion 1131 extends along the second direction Y, and the two first branch portions 1132 are respectively located on both sides of the first main body portion 1131. The second touch control electrode 123 includes one second main body portion 1231 and two second branch portions 1232. The second main body portion 1231 extends along the first direction X, and the two second branch portions 1232 are respectively located on both sides of the second main body portion 1231. Here, the first branch portion 1132 includes a plurality of first branch bars 1133 arranged at intervals, and the second branch portion 1232 includes a plurality of second branch bars 1233 arranged at intervals.

[0040] In the display panel 01 provided by the present application, since the first branch portion 1132 includes a plurality of first branch bars 1133 arranged at intervals, the capacitive coupling amount of the first touch control electrode 113 can be increased. Since the second branch portion 1232 includes a plurality of second branch bars 1233 arranged at intervals, the capacitive coupling amount of the second touch control electrode 123 can be increased. Thereby, the touch control accuracy of the capacitive touch control unit 10 can be improved, and the problem that the quality of capacitive touch control deteriorates due to the reduction of the area of the touch control electrode unit TRD can be avoided.

[0041] Preferably, the two first branch portions 1132 located on both sides of the first main body portion 1131 are axially symmetric with respect to the first main body portion 1131, and the two second branch portions 1232 located on both sides of the second main body portion 1231 are axially symmetric with respect to the second main body portion 1231.

Here, the first portion 041 and the third portion 042 are located in the first touch control layer 04, and the second portion 051 and the fourth portion 052 are located in the second touch control layer 05.

[0044] In the display panel 01 provided by the present application, the first portion 041 overlaps with the second capacitance touch control channel 12, and the third portion 042 overlaps with the second electromagnetic touch control channel 22. That is, the first portion 041 belongs to the bridge portion of the capacitance touch control unit 10, and the third portion 042 belongs to the bridge portion of the electromagnetic touch control unit 20. The second portion 051 does not overlap with the second electromagnetic touch control channel 22, and the fourth portion 052 does not overlap with the second electromagnetic touch control channel 22.

[0048] In some embodiments of the present application, the touch control layer 03 is disposed on the display side of the main body 02 of the display panel, where the display side refers to the side where a user can view the display screen of the display panel 01. Here, the first touch control layer 04 and the second touch control layer 05 are sequentially laminated on the display side of the main body 02 of the display panel, and a touch control insulating layer 06 is disposed between the first touch control layer 04 and the second touch control layer 05. Of course, the present application does not limit the relative positional relationship between the first touch control layer 04 and the second touch control layer 05 with respect to the main body 02 of the display panel. For example, in other embodiments of the present application, the second touch control layer 05 and the first touch control layer 04 are sequentially laminated and disposed on the display side of the main body 02 of the display panel.

[0050] Embodiment 2 FIG. 8 is a top schematic view showing a capacitive touch control unit and an electromagnetic touch control unit according to Embodiment 2 of the present application. As shown in combination with FIGS. 1, 3-4, 7-8, Embodiment 2 of the present application provides a display panel 01 and a display device. The display panel 01 includes a touch control layer 03.

The first capacitive touch control channels 11 extend along the second direction Y, and the second capacitive touch control channels 12 extend along the first direction X. The electromagnetic touch control unit 20 includes a plurality of first electromagnetic touch control channels 21 arranged at intervals along the first direction X and a plurality of second electromagnetic touch control channels 22 arranged at intervals along the second direction Y.

Here, the first direction X intersects the second direction Y. The first capacitive touch control channels 11 are arranged insulatedly between two adjacent first electromagnetic touch control channels 21, and the second capacitive touch control channels 12 are arranged insulatedly between two adjacent second electromagnetic touch control channels 22. The display device includes a housing and the display panel 01. Here, the housing has an accommodation space, and the display panel 01 is arranged in the accommodation space.

[0051] It should be noted that the configurations of the display panel 01 and the display device according to Embodiment 2 of the present application are similar to the configurations of the display panel 01 and the display device according to Embodiment 1 of the present application.
