Abstract
Provided is a moved touch sensing method. The moved touch sensing method according to an exemplary embodiment of the present invention includes: acquiring channel information corresponding a touch inputted into a contact region; converting each of first channel information and second channel information acquired as the touch moves into order information according to a predetermined order; and outputting a movement distance clock signal representing a movement distance of the touch on the basis of the converted order information. According to exemplary embodiments of the present invention, it is possible to reduce a burden of a control processor by outputting information regarding a movement distance and a movement direction of a moved touch by using two clock signals.
