Abstract: An electrical touch sensor is provided. The electrical touch sensor includes: a touch detection part having at least one touch pad and generating a first signal having a same delay time regardless of whether the object is in contact with the touch pad and a second signal having a varied delay time according to whether the object is in contact with the touch pad; and a contact signal generator generating a contact signal in response to the delay time-difference between the first and second signals.Therefore, it is possible to increase operation reliability by precisely determining whether the object is in contact with the pad, when the object has charge accumulation characteristics more than a certain level, although its conductive is insufficient. In addition, the electrical touch sensor can determine whether the object is in contact with the pad using only one pad to reduce a layout area of a product.
