Abstract:
A display device integrated with a touch screen and a method for driving the same are disclosed, in which parasitic capacitance is prevented from being generated. The display device comprises a panel including a plurality of electrodes; a rear resistance film provided on the plurality of electrodes of the panel; a touch integrated circuit (IC) applying a touch driving signal to the plurality of electrodes when a driving mode of the panel is a touch driving mode; and a gate driver sequentially applying scan signals to the plurality of gate lines and a data driver applying a data voltage to the plurality of data lines, when the driving mode of the panel is a display driving mode, wherein the touch driving signal or a signal corresponding to the touch driving signal is applied to the rear resistance film when the driving mode of the panel is the touch driving mode.
