1. A touch panel, comprising:
a plurality of first channels parallel to each other and extending along a first direction;
a plurality of second channels parallel to each other and extending along a second direction; and
a plurality of third channels parallel to the first channels, wherein the third channels are arranged on at least an edge of the touch panel;
wherein a distance between a central axis of the third channel and a central axis of the adjacent first channel is less than a distance between central axes of each two adjacent first channels, and a width of each third channel along a direction perpendicular to the first direction is equal to a width of each first channel along the direction perpendicular to the first direction.
 
11. A touch device, comprising a display panel and a touch panel, wherein the touch panel is located in a light emitting direction of the display panel, and the touch panel comprises:
a plurality of first channels parallel to each other and extending along a first direction;
a plurality of second channels parallel to each other and extending along a second direction; and
a plurality of third channels parallel to the first channels, wherein the third channels are arranged on at least an edge of the touch panel;
wherein a distance between a central axis of the third channel and a central axis of the adjacent first channel is less than a distance between central axes of each two adjacent first channels, and a width of each third channel along a direction perpendicular to the first direction is equal to a width of each first channel along the direction perpendicular to the first direction.
