Abstract: The present inventive concepts relate to a noise compensation device and method of a touch-sensing panel, and to a noise avoiding device and method. The noise compensation device of a touch-sensing device according to some example embodiments includes: a noise compensation signal generator configured to generate mutually different noise compensation signals for at least portions of first to Nth channels included in the touch-sensing panel; and a noise cancelling signal output circuit configured to generate noise-compensated reception signals based on the mutually different noise compensation signals and provide the noise-compensated reception signals to each of at least two channels among the first to Nth channels, wherein N is an integer two or greater.
