Touch sensor with sliding structure

A touch sensor with a sliding structure, comprising:

• a first touch detecting plate, comprising a first tilt portion;
• a second touch detecting plate, comprising a second tilt portion, wherein a bevel edge of the second tilt portion is parallel to a bevel edge of the first tilt portion, and the first touch detecting plate and the second touch detecting plate form a parallelogram slide detecting area;
• and
• a capacitance-to-digital converter, having a first input terminal and a second input terminal, wherein the first touch detecting plate at one side of the slide detecting area is coupled to the first input terminal for transmitting a first detected capacitance, and the second touch detecting plate at another side of the slide detecting area is coupled to the first input terminal or the second input terminal for transmitting a second detected capacitance;
• wherein the capacitance-to-digital converter generates a sliding state detected value according to the first detected capacitance and the second detected capacitance.
