Abstract:
A display device includes a display panel including data lines, gate lines crossing the data lines, and pixels arranged in a matrix form, a touch screen which is embedded in the display panel or is installed on the display panel, a data driving circuit supplying a data voltage to the data lines, a gate driving circuit supplying a gate pulse to the gate lines, and a touch sensing circuit which supplies a driving signal to lines of the touch screen and senses a touch input. The gate driving circuit alternately drives pull-down transistors connected in parallel to one gate line. The gate driving circuit drives one of the pull-down transistors or simultaneously drives the pull-down transistors during a drive period of the touch screen.
