Abstract: A touch sensing device includes: a touch panel on which a plurality of touch sensor electrodes are formed; a touch driver for supplying a touch driving signal to the touch sensor electrodes and receiving a touch detection signal generated by the touch driving signal; a touch controller for storing a history indicating that respective touch sensor electrodes are touched in the memory by using the touch detection signal; and a memory configured to communicate with the touch controller, wherein the touch controller controls the touch driver to read the history from the memory, determines electrodes for which a number of touch events is greater than a threshold number of touch events by using the history, and supply the touch driving signal to the determined electrodes.
