Abstract

An embodiment provides a touch circuit including a touch driving circuit supplying touch driving signals to touch electrodes, a touch sensing circuit sensing capacitance changes of the touch electrodes through touch sensing lines, and multiplexers, connected with the touch sensing lines, each transferring a capacitance change of a touch electrode to the touch sensing circuit. Some of the touch electrodes of the touch circuit are selectively short-circuited depending on a driving mode of the touch circuit and the touch electrodes are electrically connected with each other through the connection of nodes of the touch electrodes.
