Abstract
Disclosed are a capacitance-type touch panel device and an operation method for the same. In order that the effect of disturbance noise comprised in a receiving signal is minimized, a calculation for a digital code which has been converted into a digital signal type is performed. Information about the noise level of the digital code is compared to a reference value, and, when the frequency of the noise is determined to be similar to the frequency of the receiving signal, the frequency of an operation signal, which is supplied from a signal generation unit, is changed.
