The present disclosure is related to a touch sensing system and a display apparatus including: a touch screen panel defining sensor nodes by first lines and second lines formed in crossing directions, a loop type antenna, and a touch processor that performs a first touch process by receiving a signal with respect to driving pulses applied to each of the first lines and the second lines, through the antenna, and performs a second touch process by sequentially applying the driving pulses to each of two or more selected lines among the first lines and the second lines and by receiving a signal through the antenna.
