A touch sensitive display device, a method for driving the same, and a driving circuit of the display device are disclosed. The touch sensitive display device comprises a display panel comprising a plurality of pixels and a plurality of touch sensors. Each touch sensor is connected to at least one respective pixel of the pixels, the display panel driven in a plurality of successive display frame periods and during each display frame period a respective frame of image data is driven to the pixels. A touch driving circuit drives touch driving signals to the touch sensors during a touch frame that begins in a first display frame period of the display frame periods and ends in a second display frame period of the display frame periods that immediately follows the first display frame period.

Display device, method for driving the same, and driving circuit thereof

In touch panel display device, a first touch electrode group has a first plurality of touch electrodes and a second touch electrode group has a second plurality of touch electrodes. A first current supplier circuit supplies a first current during a first current supply period to the first touch electrode group, and the second current supplier circuit supplies a second current during a second current supply period to the second touch electrode group. The sensing signal receiver circuit holds a first touch voltage for the first touch electrode group following the first current supply period, and holds the second touch voltage for the second touch electrode group following the second current supply period. The sensing signal receiver determines based on the first held touch voltage and the second held touch voltage, whether a touch occurred in each of the first touch electrode group and the second touch electrode group.
