Display device with integrated touch screen and method of driving the same

A display device with integrated touch screen, comprising:

• a panel including a plurality of electrodes;
• a data driver for converting RGB data inputted from a timing controller into a data voltage, and supplying the data voltage to data lines;
• a gate driver for sequentially supplying a gate-on signal to first to nth gate lines so as to apply the data voltage to pixels of the panel when a driving mode of the panel is a display driving mode;
• and
• a touch IC for generating a touch scan signal and supplying the touch scan signal to the plurality of electrodes of the panel when a driving mode of the panel is a touch driving mode,
• wherein the gate driver sequentially supplies the gate-on signal to the first to nth gate lines, divides the gate lines into at least two groups, and then separately supplies the gate-on signal by group, and
• the data driver supplies the data voltage of the same level to the data lines.

A method of driving a display device with integrated touch screen comprising a panel including a plurality of electrodes, a data driver for supplying a data voltage to data lines, a gate driver for supplying a gate-on signal to first to nth gate lines, and a touch IC for applying a touch scan signal to the panel, comprising:

• converting RGB data into the data voltage, and supplying the data voltage to the data lines;
• when a driving mode of the panel is a display driving mode, sequentially supplying the gate-on signal to first to nth gate lines so as to apply the data voltage to pixels of the panel, simultaneously supplying the gate-on signal to the first to nth gate lines, and supplying the data voltage of the same level to the data lines;
• and
• when a driving mode of the panel is a touch driving mode, generating the touch scan signal and applying the touch scan signal to the plurality of electrodes of the panel.
