Abstract
A display device with an integrated touch screen and a method of driving the same are provided. The display device with an integrated touch screen includes a gate driver that is configured with a plurality of stages that include a pull-up transistor and first and second pull-down transistors and are respectively connected to a plurality of gate lines. The method includes: turning on the pull-up transistor to output a pull-up signal to each of the plurality of gate lines and, after the pull-up signal is outputted, turning on the first pull-down transistor to output a pull-down signal to each of the plurality of gate lines, during an image output period in each frame; and turning on the second pull-down transistor to output the pull-down signal to each of the plurality of gate lines, during a touch sensing period in each frame.
