1. An electronic device, comprising:
a touch-sensing unit; and
a light source, disposed adjacent to the touch-sensing unit;
wherein a light source driving signal of the light source has a voltage change period and a light source switching period, the touch-sensing unit performs a sensing operation in a sensing period, and the voltage change period and the sensing period at least partially overlap;
wherein a length of the voltage change period is longer than a length of the sensing period;
wherein a start point of the light source switching period is located at a midpoint between a start point of the voltage change period and a start point of the sensing period, an end point of the light source switching period is located at a midpoint between an end point of the voltage change period and an end point of the sensing period.
