Abstract
A touch sensor with a sliding structure is disclosed. The touch sensor includes a first touch detecting plate, a second touch detecting plate, and a capacitance-to-digital converter. The first touch detecting plate includes a first tilt portion, and the second touch detecting plate includes a second tilt portion, wherein a bevel edge of the second tilt portion is parallel to a bevel edge of the first tilt portion. The first touch detecting plate and the second touch detecting plate form a parallelogram slide detecting area. The first touch detecting plate transmits a first detected capacitance, and the second touch detecting plate transmits a second detected capacitance. The capacitance-to-digital converter generates a sliding state detected value according to the first detected capacitance and the second detected capacitance.
