Abstract
Exemplary embodiments of the present invention relate to a touch technology, and more specifically, to a signal control circuit, a power control circuit, a drive circuit, a timing controller, a touch system, and a touch sensitive display device and a driving method thereof that can simply swing various voltages in a display device for a touch mode period by using a modulated ground voltage obtained by swinging a ground voltage, thereby effectively providing touch driving and preventing unnecessary parasitic capacitance from being generated not only in an active area but also in all other areas.
