    Abstract: A touch sensitive display device (10), a method for driving the same, and a driving circuit of the display device (10) are disclosed. The touch sensitive display device (10) comprises a display panel (DIS) comprising a plurality of pixels (101) and a plurality of touch sensors (C1, ..., C4). Each touch sensor is connected to at least one respective pixel of the pixels (101), the display panel (DIS) driven in a plurality of successive display frame periods (Fn-1, Fn, Fn+1) and during each display frame period a respective frame of image data is driven to the pixels (101). A touch driving circuit (18) drives touch driving signals (Tx) to the touch sensors (C1, ..., C4) during a touch frame (TF) that begins in a first display frame period of the display frame periods (Fn-1, Fn, Fn+1) and ends in a second display frame period of the display frame periods (Fn-1, Fn, Fn+1) that immediately follows the first display frame period.

    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 (GND_PWM) 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.
