The first capacitive touch control channels 11 are insulatingly arranged between two adjacent first electromagnetic touch control channels 21, and the second capacitive touch control channels 12 are insulatingly arranged between two adjacent second electromagnetic touch control channels 22.

[0032] For the display panel 01 provided by the present application, since the first capacitive touch control channels 11 are arranged between two adjacent first electromagnetic touch control channels 21, in a direction perpendicular to the plane where the display panel 01 is located, the first electromagnetic touch control channels 21 and the first capacitive touch control channels 11 do not overlap. Since the second capacitive touch control channels 12 are arranged between two adjacent second electromagnetic touch control channels 22, in a direction perpendicular to the plane where the display panel 01 is located, the second electromagnetic touch control channels 22 and the second capacitive touch control channels 12 do not overlap. Thus, the capacitive touch control part 10 and the electromagnetic touch control part 20 can share the space in the direction perpendicular to the plane where the display panel 01 is located, realizing the architectural design that both the capacitive touch control part 10 and the electromagnetic touch control part 20 are arranged in the touch control layer 03, achieving the purpose of reducing the thickness of the display panel 01 and simplifying the production and preparation process.

[0033] Moreover, since the first capacitive touch control channels 11 and the first electromagnetic touch control channels 21 are insulatingly arranged, and the second capacitive touch control channels 12 and the second electromagnetic touch control channels 22 are insulatingly arranged, while the display panel 01 has the functions of electromagnetic touch control and capacitive touch control, the electromagnetic touch control signals and the capacitive touch control signals do not interfere with each other.

[0034] In some embodiments of the present application, the first direction X is Figure 2 the horizontal direction in Figure 2 and the second direction Y is Figure 2 the vertical direction in Figure 2the longitudinal direction in it, and the second direction Y is Figure 2 the lateral direction in it.

[0040] In some embodiments of the present application, two first electromagnetic touch channels 21 are arranged between any two adjacent first capacitive touch channels 11; two second electromagnetic touch channels 22 are arranged between any two adjacent second capacitive touch channels 12.

[0041] In the display panel 01 provided by the present application, since two first electromagnetic touch channels 21 are arranged between any two adjacent first capacitive touch channels 11; two second electromagnetic touch channels 22 are arranged between any two adjacent second capacitive touch channels 12, the touch accuracy of the electromagnetic touch part 20 can be greatly improved, and the electromagnetic touch quality can be improved.

[0042] Further, the first capacitive touch channels 11 located at the edge of the display panel 01 are first edge capacitive touch channels 110, and two first electromagnetic touch channels 21 are arranged on the side of the first edge capacitive touch channels 110 away from other first capacitive touch channels 11, and the two first electromagnetic touch channels 21 belong to different first electromagnetic touch channel groups 40; the second capacitive touch channels 12 located at the edge of the display panel 01 are second edge capacitive touch channels 120, and two second electromagnetic touch channels 22 are arranged on the side of the second edge capacitive touch channels 120 away from other second capacitive touch channels 12, and the two second electromagnetic touch channels 22 belong to different second electromagnetic touch channel groups 50.

[0043] In the display panel 01 provided by the present application, since two first electromagnetic touch channels 21 are arranged on the side of the first edge capacitive touch channels 110 away from other first capacitive touch channels 11, and the two first electromagnetic touch channels 21 belong to different first electromagnetic touch channel groups 40, the first electromagnetic touch channel group 40 located at the edge of the display panel 01 can also achieve a loop design with other first electromagnetic touch channel groups 40.

[0044] Similarly, in the display panel 01 provided by the present application, since two second electromagnetic touch channels 22 are provided on a side of the second edge capacitance touch channel 120 away from the other second capacitance touch channels 12, and the two second electromagnetic touch channels 22 belong to different second electromagnetic touch channel groups 50, the second electromagnetic touch channel group 50 located at the edge of the display panel 01 can also achieve a loop design with other second electromagnetic touch channel groups 50.
