Claim Text:
1. An in-cell touch display device comprising: a panel including a plurality of data lines, a plurality of gate lines, a plurality of pixels located at intersections of the gate lines and the data lines, and a plurality of touch electrodes disposed thereon, wherein a touch driving signal is applied to the plurality of touch electrodes when a driving mode is a touch mode; a data driver configured to drive the plurality of data lines; a gate driver configured to drive the plurality of gate lines, wherein the gate driver sequentially outputs a scanning signal to the plurality of gate lines when the driving mode is a display mode, and outputs a load-free driving signal having same phase as the touch driving signal to at least one gate line of the plurality of gate lines when the driving mode is the touch mode; a level shifter configured to generate the load-free driving signal; and a multiplexer configured to input a scanning voltage or the load-free driving signal to the gate driver depending on the driving mode.
