1. A sensor panel connected to an integrated circuit for detecting the position of an active stylus in a detection area, comprising:
a plurality of first electrodes which are elongated and extending along a first direction in the detection area, wherein the plurality of first electrodes are arrayed along a second direction that is transverse to the first direction;
a plurality of first routing traces associated respectively with the first electrodes and connected respectively to the first electrodes; and
a plurality of first terminals associated respectively with the first routing traces and connecting the first routing traces to the integrated circuit, wherein
the first routing traces have a first portion and a second portion physically adjacent to each other along the second direction, in a first routing trace area disposed adjacent to the detection area along the first direction,
the first portion includes the first routing traces each having a first width, and
the second portion includes the first routing traces each having a second width, wherein the first width is larger than the second width.
