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.

Abstract: A touch sensor controller may include a transmitter configured to output a driving signal to sensor lines of a touch panel, a charge amplifier configured to generate and output a voltage signal by using a charge generated in the sensor lines, a sampling circuit including a first sampler and a second sampler for detecting the voltage signal, and a logic circuit configured to determine whether the transmitter is operating according to a magnitude of a noise signal included in the voltage signal, and, in response to an operation of the transmitter being interrupted, control one of the first sampler and the second sampler to sample the voltage signal according to a sign of the noise signal.
