Claim Text:
1. A display device integrated with a touch screen, comprising: a lower substrate configuring a liquid crystal panel, a plurality of gate lines and a plurality of data lines being arranged to intersect each other in the lower substrate; an upper substrate configuring the liquid crystal panel, the upper substrate being coupled to the lower substrate with a liquid crystal layer therebetween; a pixel electrode disposed in the lower substrate; a common electrode disposed in the lower substrate or the upper substrate; a gate driver supplying a scan signal to the plurality of gate lines; a data driver supplying data voltages to the respective data lines; a touch IC supplying a touch driving signal to the data lines; a switching unit switching input or output of signals such that a display signal for image display is supplied to the liquid crystal panel during a display period, and the touch driving signal is supplied to the data lines during a non-display period; and a timing controller controlling driving of each of the gate driver, the data driver, and the touch IC, wherein the switching unit comprises a plurality of switches, and the switching unit is provided inside the data driver, wherein during the non-display period, the data lines are driven as touch driving electrodes receiving the touch driving signal, and the common electrode or the gate lines are driven as touch sensing electrodes.
