Abstract
A touch sensing system is disclosed. The touch sensing system includes an active stylus pen that generates a first pen driving signal for detecting a touch input in synchronization with a touch driving signal input from a touch screen and a second pen driving signal for detecting an additional input related to an additional function of the active stylus pen in a touch driving period and outputs the first and second pen driving signals to the touch screen; and a touch driving device that applies the touch driving signal to the touch screen, senses the first pen driving signal in a first period of the touch driving period, and senses the second pen driving signal in a second period of the touch driving period.
