CAPACITIVE TYPE TOUCH DETECTION MEANS AND DETECTION METHOD

摘要

Disclosed herein are a capacitive type touch detection means and a detection method using a new scheme, which detects a touch signal using a difference between voltage magnitudes detected by a touch detector according to whether a touch is generated, when an alternating voltage is applied to a line equivalent capacitor formed between a sensing pad which is detecting a touch signal and a non-sensing pad adjacent to the sensing pad. The touch detection means includes: a sensing pad configured to generate the touch capacitance Ct between a sensing pad and the touch input means; an alternating voltage configured to be applied to a line equivalent capacitor Ceq formed between the sensing pad and a non-sensing pad adjacent to the sensing pad; and a touch detector connected to the sensing pad to detect a difference in voltage generated according to whether the touch is generated by the touch input means.
