Abstract
The present invention relates to a device and a method for detecting a capacitive touch signal of a finger of a human body or a touch input means having similar conductive properties to the finger, and relates to a device and a method for detecting a capacitive touch signal, in which alternating driving voltage is applied to one side of a sensing equivalent capacitor formed between a sensing pad and a non-sensing pad, and a touch detection unit detects a voltage difference generated from the sensing pad according to the occurrence or non-occurrence of a touch, thereby determining whether the touch occurs or not.
