Original Abstract Submitted
An input sensing device includes first driving electrodes, second driving electrodes, and sensing electrodes, and a sensing driver that transmits a first driving signal to the first driving electrodes at a first frequency, transmits a second driving signal to the second driving electrodes at a second frequency, and determines a touch or approach of an external object based on sensing signals received from the sensing electrodes. The sensing driver includes analog front-end circuits that separate a sensing signal of the first frequency and a sensing signal of the second frequency that are received from the respective sensing electrodes, and generate digital sensing data based on a result of a recombination of the separated sensing signals.
