The electromagnetic touch portion 20 includes a plurality of first electromagnetic touch channels 21 arranged at intervals along the first direction X and a plurality of second electromagnetic touch channels 22 arranged at intervals along the second direction Y. The first electromagnetic touch channels 21 extend along the second direction Y, and the second electromagnetic touch channels 22 extend along the first direction X. The first direction X intersects the second direction Y. The first capacitive touch channels 11 are insulated between two adjacent first electromagnetic touch channels 21, and the second capacitive touch channels 12 are insulated between two adjacent second electromagnetic touch channels 22.
[0032] In the display panel 01 provided in the present application, since the first capacitive touch channel 11 is arranged between two adjacent first electromagnetic touch channels 21, the first electromagnetic touch channel 21 and the first capacitive touch channel 11 do not overlap in a direction perpendicular to the plane of the display panel 01. Since the second capacitive touch channel 12 is arranged between two adjacent second electromagnetic touch channels 22, the second electromagnetic touch channel 22 and the second capacitive touch channel 12 do not overlap in a direction perpendicular to the plane of the display panel 01. As a result, the capacitive touch portion 10 and the electromagnetic touch portion 20 can share space in a direction perpendicular to the plane of the display panel 01, realizing an architectural design in which both the capacitive touch portion 10 and the electromagnetic touch portion 20 are arranged in the touch layer 03, thereby achieving the purpose of reducing the thickness of the display panel 01 and simplifying the production and preparation process.
[0033] Furthermore, since the first capacitive touch channel 11 is insulated from the first electromagnetic touch channel 21 and the second capacitive touch channel 12 is insulated from the second electromagnetic touch channel 22, the display panel 01 has the functions of electromagnetic touch and capacitive touch, and the electromagnetic touch signal and the capacitive touch signal do not interfere with each other.
[0034] In some embodiments of the present application, the first direction X is the transverse direction in FIG. 2 , and the second direction Y is the longitudinal direction in FIG. 2 , but the present application does not limit the specific orientations of 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 longitudinal direction in FIG. 2 , and the second direction Y may be the transverse direction in FIG. 2 .
[0035] In some embodiments of the present application, the first ends 211 of every two of the first electromagnetic touch channels 21 are electrically connected to form a first electromagnetic touch channel group 40; the first ends 221 of every two of the second electromagnetic touch channels 22 are electrically connected to form a second electromagnetic touch channel group 50; wherein, the two first electromagnetic touch channels 21 in each first electromagnetic touch channel group 40 are not adjacent; and the two second electromagnetic touch channels 22 in each second electromagnetic touch channel group 50 are not adjacent.

[0044] Similarly, in the display panel 01 provided in the present application, since two second electromagnetic touch channels 22 are provided on the side of the second edge capacitive touch channel 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, the second electromagnetic touch channel group 50 located at the edge of the display panel 01 can also realize a ring design with other second electromagnetic touch channel groups 50.

[0047] Specifically, the touch electrode unit TRD can be surrounded by the first electromagnetic touch channel 21 and the second electromagnetic touch channel 22 that are arranged crosswise by reducing the area of the touch electrode unit TRD.
