Beschreibung
Zusammenfassung:	An in-cell touch display device. A panel has a plurality of data lines, a plurality of gate lines and a plurality of touch electrodes disposed thereon. A touch driving signal is applied to the plurality of touch electrodes when a driving mode is a touch mode. A data driver drives the plurality of data lines. A gate driver drives the plurality of gate lines. The gate driver sequentially outputs a scanning signal for driving the plurality of gate lines to the plurality of gate lines when the driving mode is a display mode, and outputs a load-free driving signal corresponding to the touch driving signal to at least one gate line when the driving mode is the touch mode. A level shifter generates the load-free driving signal. A multiplexer inputs a scanning voltage or the load-free driving signal to the gate driver depending on the driving mode.
