In this embodiment, the traces 53 are respectively disposed on the two extending portions 502, so that the number of the traces 53 on each extending portion 502 is reduced, and under the condition that the area of the extending portion 502 is not changed, because the space is sufficient, the traces on the extending portions 502 can be made wider, so that the traces 53 are less prone to be broken in the bending process. On the other hand, the number of the wires 53 on each of the extending portions 502 is reduced, so that each of the extending portions 502 is more easily attached to the sidewall of the display module 60 during the bending process, thereby further saving space.
Referring to fig. 7, the present invention further provides an intelligent watch 1, where the intelligent watch 1 includes a main body 3 and a touch sensing module 50 disposed in the main body 3, and the touch sensing module 50 may be the touch sensing module provided in the present invention, such as the touch sensing module of the first embodiment or the second embodiment.
