Abstract
An input sensing device includes an input sensing panel including driving electrodes and sensing electrodes, a driving signal generator that provides driving signals to the driving electrodes, respectively, and a sensing unit that receives sensing signals according to the driving signals from the sensing electrodes, and determines whether a touch is performed based on the sensing signals. Each of the driving signals includes a sinusoidal wave, and frequencies of at least some of the driving signals are different from each other.
